Well that was a fun call I just had.
Owner of the company I freelance for: Hey I forgot to tell you something.
Me: What?
Owner: I bought you a plane ticket to fly to Puerto Rico. You're heading out in a month.
Me: What?! Why????
Owner: To set up cryptocurency mining rigs.
Me: Just because I know a bit about mining doesn't make me an expert.
Owner: We have $80k in our pocket in investments from outside parties, with another $20-30k on the way. You get 20% of the coins mined for as long as you manage it.
Me: So we're gonna set up several rigs, utilizing a b250 motherboard, g4400 CPU, 8GB of RAM and 10 GPUs each. We'll have AMD rigs for monero and Nvidia rigs for Ethereum and others. We'll use awesome miner for profitability switching on the fly. Each machine is probably going to be $5k each, possibly $4k with bulk discounts. We'll need at least 1500W per rig for power, 2000W to be safe, so we need to make sure we have ample power delivery to the mining warehouse.
Owner: I thought you weren't an expert?
Me: I'm not, but when there's money involved my motivation to Google goes into overdrive.28 -
After listening to two of our senior devs play ping pong with a new member of our team for TWO DAYS!
DevA: "Try this.."
Junior: "Didn't work"
DevB: "Try that .."
Junior: "Still not working"
I ask..
Me:"What is the problem?"
Few ums...uhs..awkward seconds of silence
Junior: "App is really slow. Takes several seconds to launch and searching either crashes or takes a really long time."
DevA: "We've isolated the issue with Entity Framework. That application was written back when we used VS2010. Since that application isn't used very often, no one has had to update it since."
DevB: "Weird part is the app takes up over 3 gigs of ram. Its obviously a caching issue. We might have to open up a ticket with Microsoft."
Me: "Or remove EF and use ADO."
DevB: "That would be way too much work. The app is supposed to be fully deprecated and replaced this year."
Me: "Three of you for the past two days seems like a lot of work. If EF is the problem, you remove EF."
DevA: "The solution is way too complicated for that. There are 5 projects and 3 of those have circular dependencies. Its a mess."
DevB: "No fracking kidding...if it were written correctly the first time. There aren't even any fracking tests."
Me:"Pretty sure there are only two tables involved, maybe 3 stored procedures. A simple CRUD app like this should be fairly straight forward."
DevB: "Can't re-write the application, company won't allow it. A redesign of this magnitute could take months. If we can't fix the LINQ query, we'll going to have the DBAs change the structures to make the application faster. I don't see any other way."
Holy frack...he didn't just say that.
Over my lunch hour, I strip down the WPF application to the basics (too much to write about, but the included projects only had one or two files), and created an integration test for refactoring the data access to use ADO. After all the tests and EF removed, the app starts up instantly and searches are also instant. Didn't click through all the UI, but the basics worked.
Sat with Junior, pointed out my changes (the 'why' behind the 'what') ...and he how he could write unit tests around the ViewModel behavior in the UI (and making any changes to the data access as needed).
Today's standup:
Junior: "Employee app is fixed. Had some help removing Entity Framework and how it starts up fast and and searches are instant. Going to write unit tests today to verify the UI behaivor. I'll be able to deploy the application tomorrow."
DevA: "What?! No way! You did all that yesterday?"
Me: "I removed the Entity Framework over my lunch hour. Like I said, its basic CRUD and mostly in stored procedures. All the data points are covered by integration tests, but didn't have time for the unit tests. It's likely I broke some UI behavior, but the unit tests should catch those."
DevB: "I was going to do that today. I knew taking out Entity Framework wouldn't be a big deal."
Holy fracking frack. You fracking lying SOB. Deeeep breath...ahhh...thanks devRant. Flame thrower event diverted.13 -
So I visited my aunt's house a few days back.
They heard I write code (read: Google and copy-paste from Stack Overflow), and wanted me to help repair their computers.
Saw my cousin playing Battlefield 4 at sub-20 fps with a GTX 750 Ti on the lowest settings. His fucking CPU fan was bust, and judging by the amount of dust in his system, I literally thought he was cramming dust in there on purpose.
After a heavy dusting, another stick of RAM (4GB -> 12GB), a new heatsink (CoolerMaster T400i), and a fresh copy of Windows 10 (along with Office, etc.), he could play games at 60+ fps again.
What do I get? Not even a fucking thank you. Just a "you done yet? I want to play video games."
I mean... Gee. Your cousin flew all the way to a new continent, spent his precious vacation time helping you out, and all he gets is a cold-ass shoulder.
Even my fucking ex gave me more than that.16 -
At age of 20, I got hired as junior dev at a mobile gaming company. We were 2 junior devs hired at the same time and one of our senior colleagues made a prank: he came in the office before us and rearranged our offices in a "funny" manner.
Two days later I waited for him to go home. I opened his PC case, removed the power button cable from the motherboard and then re-arranged everything back to normal. Well, I couldn't resist...
Next day he came into the office and, well, surprise... the PC was not starting. He went to the IT department and they spent 4 hours trying to figure out why it was not working. They replaced the CPU, RAM memory, including the PSU.
I had to go and tell them: "maybe it's the power button jack?!".
I got into some problems for that prank. Indeed I crossed a line, but what the hell... that was a bad IT department.19 -
Bought that server from a friend yesterday.
About to buy a second dedicated server (second hand) with 32gb's of ram!
This is getting out of hand 😅26 -
I'm getting ridiculously pissed off at Intel's Management Engine (etc.), yet again. I'm learning new terrifying things it does, and about more exploits. Anything this nefarious and overreaching and untouchable is evil by its very nature.
(tl;dr at the bottom.)
I also learned that -- as I suspected -- AMD has their own version of the bloody thing. Apparently theirs is a bit less scary than Intel's since you can ostensibly disable it, but i don't believe that because spy agencies exist and people are power-hungry and corrupt as hell when they get it.
For those who don't know what the IME is, it's hardware godmode. It's a black box running obfuscated code on a coprocessor that's built into Intel cpus (all Intell cpus from 2008 on). It runs code continuously, even when the system is in S3 mode or powered off. As long as the psu is supplying current, it's running. It has its own mac and IP address, transmits out-of-band (so the OS can't see its traffic), some chips can even communicate via 3g, and it can accept remote commands, too. It has complete and unfettered access to everything, completely invisible to the OS. It can turn your computer on or off, use all hardware, access and change all data in ram and storage, etc. And all of this is completely transparent: when the IME interrupts, the cpu stores its state, pauses, runs the SMM (system management mode) code, restores the state, and resumes normal operation. Its memory always returns 0xff when read by the os, and all writes fail. So everything about it is completely hidden from the OS, though the OS can trigger the IME/SMM to run various functions through interrupts, too. But this system is also required for the CPU to even function, so killing it bricks your CPU. Which, ofc, you can do via exploits. Or install ring-2 keyloggers. or do fucking anything else you want to.
tl;dr IME is a hardware godmode, and if someone compromises this (and there have been many exploits), their code runs at ring-2 permissions (above kernel (0), above hypervisor (-1)). They can do anything and everything on/to your system, completely invisibly, and can even install persistent malware that lives inside your bloody cpu. And guess who has keys for this? Go on, guess. you're probably right. Are they completely trustworthy? No? You're probably right again.
There is absolutely no reason for this sort of thing to exist, and its existence can only makes things worse. It enables spying of literally all kinds, it enables cpu-resident malware, bricking your physical cpu, reading/modifying anything anywhere, taking control of your hardware, etc. Literal godmode. and some of it cannot be patched, meaning more than a few exploits require replacing your cpu to protect against.
And why does this exist?
Ostensibly to allow sysadmins to remote-manage fleets of computers, which it does. But it allows fucking everything else, too. and keys to it exist. and people are absolutely not trustworthy. especially those in power -- who are most likely to have access to said keys.
The only reason this exists is because fucking power-hungry doucherockets exist.26 -
I have been a mobile developer working with Android for about 6 years now. In that time, I have endured countless annoyances in the Android development space. I will endure them no more.
My complaints are:
1. Ridiculous build times. In what universe is it acceptable for us to wait 30 seconds for a build to complete. Yes, I've done all the optimisations mentioned on this page and then some. Don't even mention hot reload as it doesn't work fast enough or just does not work at all. Also, buying better hardware should not be a requirement to build a simple Android app, Xcode builds in 2 seconds with a 8GB Macbook Air. A Macbook Air!
2. IDE. Android Studio is a memory hog even if you throw 32GB of RAM at it. The visual editors are janky as hell. If you use Eclipse, you may as well just chop off your fingers right now because you will have no use for them after you try and build an app from afresh. I mean, just look at some of the posts in this subreddit where the common response is to invalidate caches and restart. That should only be used as a last resort, but it's thrown about like as if it solves everything. Truth be told, it's Gradle's fault. Gradle is so annoying I've dedicated the next point to it.
3. Gradle. I am convinced that Gradle causes 50% of an Android developer's pain. From the build times to the integration into various IDEs to its insane package management system. Why do I need to manually exclude dependencies from other dependencies, the build tool should just handle it for me. C'mon it's 2019. Gradle is so bad that it requires approx 54GB of RAM to work out that I have removed a dependency from the list of dependencies. Also I cannot work out what properties I need to put in what block.
4. API. Android API is over-bloated and hellish. How do I schedule a recurring notification? Oh use an AlarmManager. Yes you heard right, an AlarmManager... Not a NotificationManager because that would be too easy. Also has anyone ever tried running a long running task? Or done an asynchronous task? Or dealt with closing/opening a keyboard? Or handling clicks from a RecyclerView? Yes, I know Android Jetpack aims to solve these issues but over the years I have become so jaded by things that have meant to solve other broken things, that there isn't much hope for Jetpack in my mind 😤
5. API 2. A non-insignificant number of Android users are still on Jelly Bean or KitKat! That means we, as developers, have to support some of your shitty API decisions (Fragments, Activities, ListView) from all the way back then!
6. Not reactive enough. Android has support for Databinding recently but this kind of stuff should have been introduced from the very start. Look at React or Flutter as to how easy it is to make shit happen without any effort.
7. Layouts. What the actual hell is going on here. MDPI, XHDPI, XXHDPI, mipmap, drawable. Fuck it, just chuck it all in the drawable folder. Seriously, Android should handle this for me. If I am designing for a larger screen then it should be responsive. I don't want to deal with 50 different layouts spread over 6 different folders.
8. Permission system. Why was this not included from the very start? Rogue apps have abused this and abused your user's privacy and security. Yet you ban us and not them from the Play Store. What's going on? We need answers.
9. In Android, building an app took me 3 months and I had a lot of work left to do but I got so sick of Android dev I dropped it in favour of Flutter. I built the same app in Flutter and it took me around a month and I completed it all.
10. XML.
If you're a new dev, for the love of all that is good in this world, do NOT get into Android development. Start with Flutter or even iOS. On Flutter and build times are insanely fast and the hot reload is under 500ms constantly. It's a breath of fresh air and will save you a lot of headaches AND it builds for iOS flawlessly.
To the people who build Android, advocate it and work on it, sorry to swear, but fuck you! You have created a mess that we have to work with on a day-to-day basis only for us to get banned from the app store! You have sold us a lie that Android development is amazing with all the sweet treat names and conferences that look bubbly and fun. You have allowed to get it so bad that we can't target an API higher than 18 because some Android users are still using devices that support that!
End this misery. End our pain. End our suffering. Throw this abomination away like you do with some of your other projects and migrate your efforts over to Flutter. Please!

More sysadmin focused but y’all get this stuff and I need a rant.
TLDR: Got the wrong internship.
Start working as a sysadmin/dev intern/man-of-many-hats at a small finance company (I’m still in school). Day 1: “Oh new IT guy? Just grab a PC from an empty cubicle and here’s a flash drive with Fedora, go ahead and manually install your operating system. Oh shit also your desktop has 2g of ram, a core2 duo, and we scavenged your hard drive for another dev so just go find one in the server room. And also your monitor is broken so just take one from another cubicle.”
Am shown our server room and see that someone is storing random personal shit in there (golf clubs propped against the server racks with heads mixed into the cabling, etc.). Ask why the golf clubs etc. are mixed in with the cabling and server racks and am given the silent treatment. Learn later that my boss is the owners son, and he is storing his personal stuff in our server room.
Do desktop support for end users. Another manager asks for her employees to receive copies of office 2010 (they’re running 2003 an 2007). Ask boss about licensing plans in place and upgrade schedules, he says he’ll get back to me. I explain to other manager we are working on a licensing scheme and I will keep her informed.
Next day other manager tells me (*the intern*) that she spoke with a rich business friend whose company uses fake/cracked license keys and we should do the same to keep costs down. I nod and smile. IT manager tells me we have no upgrade schedule or licensing agreement. I suggest purchasing an Office 365 subscription. Boss says $150 a year per employee is too expensive (Company pulls good money, has ~25 employees, owner is just cheap) I suggest freeware alternatives. Other manager refuses to use anything other than office 2010 as that is what she is familiar with. Boss refuses to spend any money on license keys. Learn other manager is owners wife and mother of my boss. Stalemate. No upgrades happen.
Company is running an active directory Windows Server 2003 instance that needs upgrading. I suggest 2012R2. Boss says “sure”. I ask how he will purchase the license key and he tells me he won’t.
I suggest running an Ubuntu server with LDAP functionality instead with the understanding that this will add IT employee hours for maintenance. Bosses eyes glaze over at the mention of Linux. The upgrade is put off.
Start cleaning out server room of the personal junk, labeling server racks and cables, and creating a network map. Boss asks what I’m doing. I show him the organized side of the server room and he says “okay but don’t do any more”.
... *sigh* ...20 -
So I finally got my head out of my ass and decided to install some OS on that 500MB RAM legacy craptop from earlier.
*installs Tiny Core Linux*
Hmm.. how do I install extra packages into this thing again? *Googles how to install packages*
Aha, extensions it's called.. and you install them through their little package manager GUI, and then you also have to dick around with some TCE directory, and boot options for that. Well I ain't gonna do that. Why the fuck would I need to dick around with that? Just install the fucking files in /bin, /var, /etc and whatever the fuck you need to like a decent distro. I'll fucking load them whenever I need them, BY EXECUTING THE FUCKING BINARY. But no, apparently that's not how TCL works.
Also, why the fuck is this keyboard still set to US? I'm using a Belgian keyboard for fuck's sake.. "loadkeys be-latin1"
> Command not found.
Okay... (fucking piece of shit) how do I change the fucking keyboard layout for this shit?!
*does the jazz hand routine required for that*
So apparently I need to install a package for that as well. Oh wait, an EXTENSION!! My bad. And then you can use "loadkmap < /usr/share/kmap/something/something" to load the keyboard layout. Except that it doesn't change the fucking keymap at all! ONE FUCKING JOB, YOU PIECE OF SHIT!!!
That's fucking it. No more dicking around in TCL. If I wanted to fuck around with the system this much, I'd have compiled my own custom Linux system. Maybe I can settle with Arch Linux, that's a familiar distro to me.. I can easily install openbox in that and call it a day. But this is an i686 machine.. Arch doesn't support that anymore, does it?
*does another jazz hand routine on Arch Linux 32 and sees that there's a community-maintained project just for that*
Oh God bless you fine Arch Linux users for making a community fork!! I fucking love you.. thank you so much!! Arch it'll be then <318 -
About two years ago I get roped into a something when someone was requesting an $8000 laptop to run an "program" that they wrote in Excel to pull data from our mainframe.
In reality they are using our normal application that interacts with the mainframe and screen scrapping it to populate several Excel spreadsheets.
So this guy kept saying that he needed the expensive laptop because he needed the extra RAM and processing power for his application. At the time we only supported 32 bit Windows 7 so even though I told him ten times that the OS wouldn't recognize more than 3.5 GB of RAM he kept saying that increasing the RAM would fix his problem. I also explained that even if we installed the 64 bit OS we didn't have approval for the 64 bit applications.
So we looked at the code and we found that rather than reusing the same workbook he was opening a new instance of a workbook during each iteration of his loop and then not closing or disposing of them. So he was running out of memory due to never disposing of anything.
Even better than all of that, he wanted a faster processor to speed up the processing, but he had about 5 seconds of thread sleeps in each loop so that the place he was screen scrapping from would have time to load. So it wouldn't matter how fast the processor was, in the end there were sleeps and waits in there hard coded to slow down the app. And the guy didn't understand that a faster processor wouldn't have made a difference.
The worst thing is a "dev" that thinks they know what they are doing but they don't have a clue.7 -
Today, I was told to investigate why the software doesn't work on "some" computers. I had no previous experience with that particular software but I just had to make some tests... easy, right? As soon as I ran the software, my computer crashed (I literally had to restart the pc). I asked my colleagues if I did something wrong but the set up seemed ok.
Later, in a random discussion about the software I found out it does "a little memory allocation". I opened the performance tab in task manager and ran the software again. In an instant, the RAM went from 1.3GB to 7.66GB (my pc has 8GB of RAM).
In an attempt to find how such a monstrosity was creater, I found out the developer that made the software had 16GB of RAM on his pc.
I have found something that eats RAM more than Chrome... brace yourselves.8 -
What kind of supercomputer you have to use to get these fucking websites to work smoothly????
I'm on a fucking gigabit connection, ryzen 7 7700x, 32GB ram, and a fucking nvme, all it takes is opening a fucking recipe site and I'm instantly transported back to the 80s. I swear if i see another 4k asset I'm gonna punch something.
WHAT THE FUCK HAPPENED TO FUNCTION OVER FORM????
Oh do you want me to disable my addblocker??? How about: you make a site that works you fuck. No i will not fucking subscribe to your brain-dead newsletter why the fuck would I???
And since when are cookies needed for a fucking plaintext site you asshat??? Tracking??? I swear if you could you would generate metadata from my clipped fingernails if it meant you could stick "Big data" next to that zip-bomb you call a website.
I WOULD like to read your article, possibly even watch a couple of ads on my sidebar for you, but noooooo you had to have the stupid fucking google vinegrette or however the fuck they are calling the fucking thing now.
The age of the web sucks the happiness out of life, and despite having all of this processing power, I am jealous of my fathers RSS feeds.
I'm sorry web people, I know it's not your fault, I know designers and management don't give a shit how long a website takes to load. I just wanted to make a fucking omelette.15 -
I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.
So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.
It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.
Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).
Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!
The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.
Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.
So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.
There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D12 -
My first internship was unpaid. "For the experience" and shit. My first task was to clear out an entire office full to the literal ceiling with the phones of people who had been laid off or quit. There were now just three old guys in the entire office. And me. Go figure. I need to find that picture, it's truly unbelievable.
My next task was to sort cables in the store room. Mind you, this was supposed to be a software dev internship.
I consistently had to ASK for work to do. If I didn't, I would just sit in my new office all day doing homework and playing with linux liveCDs and nobody cared.
So the third task they gave me was to try to restore a very old (like XP old) computer that had a broken hard drive, literally broken. Said they wanted to "repurpose it." As busy work I guess.
So I scrounged around the cleptomaniacal cesspool of dated and neglected tech and found a hard drive. Pop it in, chkdsk, fdisk, good to go. Spend hours installing XP while sorting more random cables and doing my homework because honestly writing a history paper is more valuable to my dev career than this complete bullshit. Finally get the thing working and go to report the miracle of rebirth to my higher-up. He says "oh cool," doesn't smile, and hands me a list of software to install.
I come back 20 minutes later - "Hey, most of these require corporate licenses."
Guy says "yup" and goes back to ignoring me. Never gives me a company card to buy licenses, or a list of ones already bought. I've revived the computer equivalent of Moses from the computer equivalent of permadeath just for this asshole to completely disregard that and give me an(other) impossible task, just to get me off his back. Excuse me for imposing with free (then-child) labor, you ass.
I spend maybe another week there doing homework in the office I cleaned and contemplating stealing everything of value. I guarantee they wouldn't have noticed though, which somehow made the idea less appealing.
I quit by texting my boss.
He never replied.
I wish I had stolen their laptop RAM.
It's probably still sitting on boss's shelf collecting dust and being a miserable, outdated fucking waste of space, just like him and his two remaining coworkers.4 -
I tried the beta version of Mozilla Firefox Browser.
I opened 10 sites which consists of social media, email and youtube. And I found out it consumes less RAM resources than Google Chrome. Not bad Mozilla.
Here is an article about it: https://thenextweb.com/tech/2017/...25 -
Made a program to list primes until stopped. I got to about 2 billion when it took 8 GB of RAM and I more or less had to stopped it.
Only took 10% of CPU though.13 -
!rant & story_time
This happend to the startup I was working for at ~2011. I was a junior Android dev, working on a very popular app.
During experiments for a new feature, I discovered that the system AlarmManager has a serious bug - you can set a repeating alarm with interval=0ms. If your app takes more then 1 ms to handle the Intent, then the AlarmManager will start to fill up the intent Queue, with unexpected results to the OS. causing it to slow down, and reboot when it ran out of Ram. Why? my guess was that because the AlarmManager was part of the OS, then any issues caused by it caused the system process to ran out of ram, crashing it, and the whole system with it. the real kicker was that even after a reboot, the AlarmManager still had Intents queued, causing the device to bootloop for a while, untill the queue was cleared. My boss decided to report the problem to google, as this was an issue in the OS. I built an example app, that caused the crash 10-30 seconds after starting, and submitted to Google. Google responded later that day with "not an issue, no one will ever do this".
Well... At this point I decided to review the autoupdate feature in our app, to make sure this will not happen to us. We just released a new feature where a user can set an update schedule option in the app settings - where you could setup a daily, weekly, or hourly update for the app. after reviewing it, It looked good, and the issue was not triggered in the manual QA I did. So, it was all good. And we released an updated version to the store.
After we did an update-install, we discoverd that, there was a provlem reading the previous version SharedPrefs value for the update schdule settings, and the value defaulted to 0...
the result was, our app caused all our users to go into a bootloop, and because the alarm was reset when the devices booted up, the bootloop could only be solved in a factory reset, or removing our app, before the device rebooted, and then waiting a few reboot cycles.
We lost 50 places in the market, and it took us 6 months to get back to where we were.
It was not my fault, but it sucked big time!4 -
I have a laptop which I bought for the sole purpose of gaming and I bought a hell lot of games off steam to startup.
But the problem here is I have to run those games on Windows (nvidia graphics card) and I only have a primary hdd and no ssd. Even though the ram and processor is up to speed due to high I/O on disk, I am not able to get a good performance out of it. To top it off random Windows processes hogging hdd in the background.
Any suggestions on what to do?3 -
The tech stack at my current gig is the worst shit I’ve ever dealt with...
I can’t fucking stand programs, especially browser based programs, to open new windows. New tab, okay sure, ideally I just want the current tab I’m on to update when I click on a link.
Ticketing system: Autotask
Fucking opens up with a crappy piss poor sorting method and no proper filtering for ticket views. Nope you have to go create a fucking dashboard to parse/filter the shit you want to see. So I either have to go create a metric-arse tonne of custom ticket views and switch between them or just use the default turdburger view. Add to that that when I click on a ticket, it opens another fucking window with the ticket information. If I want to do time entry, it just feels some primal need to open another fucking window!!! Then even if I mark the ticket complete it just minimizes the goddamn second ticket window. So my jankbox-supreme PC that my company provided gets to strugglepuff along trying to keep 10 million chrome windows open. Yeah, sure 6GB of ram is great for IT work, especially when using hot steaming piles of trashjuice software!
I have to manually close these windows regularly throughout the day or the system just shits the bed and halts.
RMM tool: Continuum
This fucker takes the goddamn soggy waffle award for being utterly fucking useless. Same problem with the windows as autotask except this special snowflake likes to open a login prompt as a full-fuck-mothering-new window when we need to open a LMI rescue session!!! I need to enter a username and a password. That’s it! I don’t need a full screen window to enter credentials! FUCK!!! Btw the LMI tools only work like 70% of the time and drag ass compared to literally every other remote support tool I’ve ever used. I’ve found that it’s sometimes just faster to walk someone through enabling RDP on their system then remoting in from another system where LMI didn’t decide to be fully suicidal and just kill itself.
Our fucking chief asshat and sergeant fucknuts mcdoogal can’t fucking setup anything so the antivirus software is pushed to all client systems but everything is just set to the default site settings. Absolutely zero care or thought or effort was put forth and these gorilla spunk drinking, rimjob jockey motherfuckers sell this as a managed AntiVirus.
We use a shitty password manager than no one besides I use because there is a fully unencrypted oneNote notebook that everyone uses because fuck security right? “Sometimes it’s just faster to have the passwords at the ready without having to log into the password manager.” Chief Asshat in my first week on the job.
Not to mention that windows server is unlicensed in almost every client environment, the domain admin password is same across multiple client sites, is the same password to log into firewalls, and office 365 environments!!!
I’ve brought up tons of ways to fix these problems, but they have their heads so far up their own asses getting high on undeserved smugness since “they have been in business for almost ten years”. Like, Whoop Dee MotherFucking Doo! You have only been lucky to skate by with this dumpster fire you call a software stack, you could probably fill 10 olympic sized swimming pools to the brim with the logarrhea that flows from your gullets not only to us but also to your customers, and you won’t implement anything that is good for you, your company, or your poor clients because you take ten minutes to try and understand something new.
I’m fucking livid because I’m stuck in a position where I can’t just quit and work on my business full time. I’m married and have a 6m old baby. Between both my wife and I working we barely make ends meet and there’s absolutely zero reason that I couldn’t be providing better service to customers without having to lie through my teeth to them and I could easily support my family and be about 264826290461% happier!
But because we make so little, I can’t scrap together enough money to get Terranimbus (my startup) bootstrapped. We have zero expendable/savable income each month and it’s killing my soul. It’s so fucking frustrating knowing that a little time and some capital is all that stands between a better life for my family and I and being able to provide a better overall service out there over these kinds of shady as fuck knob gobblers.5 -
I like memory hungry desktop applications.
I do not like sluggish desktop applications.
Allow me to explain (although, this may already be obvious to quite a few of you)
Memory usage is stigmatized quite a lot today, and for good reason. Not only is it an indication of poor optimization, but not too many years ago, memory was a much more scarce resource.
And something that started as a joke in that era is true in this era: free memory is wasted memory. You may argue, correctly, that free memory is not wasted; it is reserved for future potential tasks. However, if you have 16GB of free memory and don't have any plans to begin rendering a 3D animation anytime soon, that memory is wasted.
Linux understands this. Linux actually has three States for memory to be in: used, free, and available. Used and free memory are the usual. However, Linux automatically caches files that you use and places them in ram as "available" memory. Available memory can be used at any time by programs, simply dumping out whatever was previously occupying the memory.
And as you well know, ram is much faster than even an SSD. Programs which are memory heavy COULD (< important) be holding things in memory rather than having them sit on the HDD, waiting to be slowly retrieved. I much rather a web browser take up 4 GB of RAM than sit around waiting for it to read the caches image off my had drive.
Now, allow me to reiterate: unoptimized programs still piss me off. There's no need for that electron-based webcam image capture app to take three gigs of memory upon launch. But I love it when programs use the hardware I spent money on to run smoother.
Don't hate a program simply because it's at the top of task manager.6 -
Okay lets write this before i go mad...
I'm one of those guys who says "use the os which suits you the most, or you're most familiar with", and i'v always been a windows guy, didn't really have any reason to use linux, because for school stuff, or programming (java and android and c) windows was great enough...
BUT MOTHERF@CKERS at microsoft, i'v had enough...
First my handheld computer goes nuts, because windows is eating 80% of processor, and if i fix it, then some other kind of windows related thing eats up that much, and you know what? I've been okay with that, because thats only a handheld computer, but boy, didn't my main computer start to do the same?!?
I cannot do anything, basically i start something trivial up (by trivial i mean trivial, like idk, a texteditor not even a browser, or an ide or anything that would take a bit of more ram) and my computer cant do shit....
I'm so mad.... Currently installing elemantary os... F@ck this shit i'm out...
(And lets not forget the hours of 'updates' which dont do shit....)13 -
This happend to me around 2 weeks ago. For some reason, I decied to post this now.
I won the lottery, yey! I mean, bot really, but I am <19yo student, "less than junior dev" in my office, but sonce I am the only one who is capable of working with hardware, I was working month back as a sysadmin for a few days. Our last sysadmin was really good working but really, really toxic guy, so he got fired on a spot after argument with some manager or whatever, no big deal, we could have another guy hired in a week. But, our backup server literally was on fire, all data probably dead because bad capacitor or whatever. This was our only backup of everything at the time. Everyone in full fucking panic mode, we had literally no other working HW we could use for backup, but then comes me, intern employed on his first dev job for 3 months. That day I bought some HW for my own personal server at home (Intel NUC with some Celeron, 4GB DDR4 RAM and two 240GB SSDs for RAID 1. My manager asked everyone in the office for sollution how to survive next 4 days before new server arrives. People there had no idea what tk do and no knowedgle about HW, I just came from a break and offered my components for a week, since there was noone else who can work with HW, servers and stuff like this, manager offered me $500+HW cost if I, random intern, can make it work. I installed Debian on that little PC, created RAID1 from both SSDs, installed MySQL server and mirrored GIT server from our last standing server (we had two before one of them went lit 🔥), made simple Python script to copy all data on that RAID, with some help of our database guy copied whole DB from production to this little computer and edited some PHP so every SQL request made on our server will run on that NUC too. Everything after ±2 hours worked perfectly. Untill a fucking PSU burned in our server and took RAID controller with him in sillicon heaven next night, so we could not access any data unltill we got a new one. Thanks to every god out there, I was able to create software RAID from survived HDDs on our production server and copy all data from that NUC on the servers software RAID and make it working at 3 AM in the night before an exam 😂. Without this, we would be next ±40 hours without aerver running and we might loose soke of our data and customers. So my little skill with Linux, Python, MySQL and most importantly my NUC hardware I got that day running as a backup server saved maybe whole company 😂.
Btw, guess who is now employee of the year with $2500 bonus? 😀
Sorry for bragging and log post, but I was so lucky an so happy when everything worked out, good luck to all sysadmins out there! 👍
TL:DR: Random intern saved company and made some money 😂7 -
I have a whatsapp group with my friends, none of which are techies. A while ago one of them was looking for a phone to buy, so he started looking at models, specs and all that, but got pretty confused and asked a pretty well-informed question to the group:
"Guys, what is that quad core thing?
And what is a RAM? Is it something like the processor of the phone or what? "
OK, pretty typical stuff up until this point. The guy knows nothing about this sort of things, I wouldn't criticize him or insult him or anything like that. No, that's not the problem. The problem is the person that responded to him. This... This melted my brain so much I will never forget:
"Don't worry about that, you only have to look at how many gigahertz does the processor run at. Don't worry about the number of cores or ram. The GHz are the result of the amount of ram and cores, so the more the gigahertz, the better the phone."
PD: "Also take a look at how many megapixels does the camera have if you want to take photos".
Some people just talk out of their ass and pretend like they're experts on any topic they've read about for 5 minutes on the Internet7 -
Around 27 hours at new customer location.
They had a server failure due to incompetence.
They had fired their own IT guy and called us 6 months later because the server stopped responding.
First diagnostic. 2 drives are dead in a raid 5 with one hot spare. Raid controller then proved to be broken once the disks was replaced.
Waiting for new raid controller and installing.
Backup non existing, no one changed dat tape during the 6 months without IT. The tape was just a transparent plastic band, no media left.
Raid config is stored in static ram on controller, no backup!
Several hours in tech support to find out how to rebuild raid config from existing disks.
Proves to be impossible to rebuild raid set due to some checksum failures.
More hours with support to enable some diagnostic read only mode to mirror low level content to external drive.
Then many more hours to copy parts of the tree until it gets an error, restart after that and go on.
In the end we got around 70% back.
During this time I manage to be in contact with the raid manufacturers all support centers, one in europe, one in the us and one in Taiwan, switching each time one if them closed for the night.
The customer later declined a steady support contract due to us being to expensive ;)
Some just don’t want to learn.6 -
To any fellow Linux sysadmin out there, is it true that 32 bits systems can handle a max of 16gb ram?
Running a 32 bits CentOS live disc in my dedi which shows 16gb ram available while the BIOS shows 32gb installed...

Welp, I just created a Minecraft server on a 48-Core Epyc with 256GB of RAM.
...I just hope I remember to turn it off when the free credits run out 😱18 -
Sooo win has updated itself (in a short 6 hours) and I was wondering what eats my pocket pc's 4 gb ram, so i checked, and turns out system is eating 40-50% of it and its processor ever since the update... *Sigh* Awesome....

*Notices that SMPlayer takes a lot of the iGPU and CPU*
*Relaunches SMPlayer to use dedicated Nvidia GPU*

> MPlayer crashed by bad usage of CPU/FPU/RAM.
(that last one is an actual log btw)
Alright, got it. I bought this fucking PC just for its fucking "powerful" GPU. It already locked me into using WanBLowS on that piece of garbage. Yet now that NvuDiA piece of garbage is gonna act worse than a fucking paperweight?! Seriously?!!
FUCK YOU NVIDIA!!! Linus Torvalds called your shitty cards shit on Linux.. I call it shit on every fucking OS out there!!! MOTHERFUCKERS!!!3 -
Not just another Windows rant:
*Disclaimer* : I'm a full time Linux user for dev work having switched from Windows a couple of years ago. Only open Windows for Photoshop (or games) or when I fuck up my Linux install (Arch user) because I get too adventurous (don't we all)
I have hated Windows 10 from day 1 for being a rebel. Automatic updates and generally so many bugs (specially the 100% disk usage on boot for idk how long) really sucked.
It's got ads now and it's generally much slower than probably a Windows 8 install..
The pathetic memory management and the overall slower interface really ticks me off. I'm trying to work and get access to web services and all I get is hangups.
Chrome is my go-to browser for everything and the experience is sub par. We all know it gobbles up RAM but even more on Windows.
My Linux install on the same computer flies with a heavy project open in Android Studio, 25+ tabs in Chrome and a 1080p video playing in the background.
Up until the creators update, UI bugs were a common sight. Things would just stop working if you clicked them multiple times.
But you know what I'm tired of more?
The ignorant pricks who bash it for being Windows. This OS isn't bad. Sure it's not Linux or MacOS but it stands strong.
You are just bashing it because it's not developer friendly and it's not. It never advertises itself like that.
It's a full fledged OS for everyone. It's not dev friendly but you can make it as much as possible but you're lazy.
People do use Windows to code. If you don't know that, you're ignorant. They also make a living by using Windows all day. How bout tha?
But it tries to make you feel comfortable with the recent bash integration and the plethora of tools that Microsoft builds.
IIS may not be Apache or Nginx but it gets the job done.
Azure uses Windows and it's one of best web services out there. It's freaking amazing with dead simple docs to get up and running with a web app in 10 minutes.
I saw many rants against VS but you know it's one of the best IDEs out there and it runs the best on Windows (for me, at least).
I'm pissed at you - you blind hater you.
Research and appreciate the things good qualities in something instead of trying to be the cool but ignorant dev who codes with Linux/Mac but doesn't know shit about the advantages they offer.undefined windows 10 sucks visual studio unix macos ignorance mac terminal windows 10 linux developer22 -
What an absolute fucking disaster of a day. Strap in, folks; it's time for a bumpy ride!
I got a whole hour of work done today. The first hour of my morning because I went to work a bit early. Then people started complaining about Jenkins jobs failing on that one Jenkins server our team has been wanting to decom for two years but management won't let us force people to move to new servers. It's a single server with over four thousand projects, some of which run massive data processing jobs that last DAYS. The server was originally set up by people who have since quit, of course, and left it behind for my team to adopt with zero documentation.
Anyway, the 500GB disk is 100% full. The memory (all 64GB of it) is fully consumed by stuck jobs. We can't track down large old files to delete because du chokes on the workspace folder with thousands of subfolders with no Ram to spare. We decide to basically take a hacksaw to it, deleting the workspace for every job not currently in progress. This of course fucked up some really poorly-designed pipelines that relied on workspaces persisting between jobs, so we had to deal with complaints about that as well.
So we get the Jenkins server up and running again just in time for AWS to have a major incident affecting EC2 instance provisioning in our primary region. People keep bugging me to fix it, I keep telling them that it's Amazon's problem to solve, they wait a few minutes and ask me to fix it again. Emails flying back and forth until that was done.
Lunch time already. But the fun isn't over yet!
I get back to my desk to find out that new hires or people who got new Mac laptops recently can't even install our toolchain, because management has started handing out M1 Macs without telling us and all our tools are compiled solely for x86_64. That took some troubleshooting to even figure out what the problem was because the only error people got from homebrew was that the formula was empty when it clearly wasn't.
After figuring out that problem (but not fully solving it yet), one team starts complaining to us about a Github problem because we manage the github org. Except it's not a github problem and I already knew this because they are a Problem Team that uses some technical authoring software with Git integration but they only have even the barest understanding of what Git actually does. Turns out it's a Git problem. An update for Git was pushed out recently that patches a big bad vulnerability and the way it was patched causes problems because they're using Git wrong (multiple users accessing the same local repo on a samba share). It's a huge vulnerability so my entire conversation with them went sort of like:
"Please don't."
"We have to."
"Fine, here's a workaround, this will allow arbitrary code execution by anyone with physical or virtual access to this computer that you have sitting in an unlocked office somewhere."
"How do I run a Git command I don't use Git."
So that dealt with, I start taking a look at our toolchain, trying to figure out if I can easily just cross-compile it to arm64 for the M1 macbooks or if it will be a more involved fix. And I find all kinds of horrendous shit left behind by the people who wrote the tools that, naturally, they left for us to adopt when they quit over a year ago. I'm talking entire functions in a tool used by hundreds of people that were put in as a joke, poorly documented functions I am still trying to puzzle out, and exactly zero comments in the code and abbreviated function names like "gars", "snh", and "jgajawwawstai".
While I'm looking into that, the person from our team who is responsible for incident communication finally gets the AWS EC2 provisioning issue reported to IT Operations, who sent out an alert to affected users that should have gone out hours earlier.
Meanwhile, according to the health dashboard in AWS, the issue had already been resolved three hours before the communication went out and the ticket remains open at this moment, as far as I know.5 -
Every time someone rants about Visual Studio I'm like: WTF are they talking about? it is the best IDE I ever used!!
but now after using VS 2017 I must say:
WHAT THE FUCK MICROSOFT DID TO THIS THING! IT RANDOMLY FREEZE EATS OUT ALL CPU AND NOW USES A GOOD 1.5GB RAM!
my previous experience:
barely 20% of CPU
at max 700MB RAM
Guess those days are over :\13 -
Contenders for arseholes this week
- Elasticsearch as their implemented product identification and integration in client libraries like Python to exclude OpenSearch made a lot of things very painful. Yay....
- Microsoft decided to integrate kill switches in Exchange. Yeah.... Great stuff.
- Atlassian has another week of dumbness - after they botch release after release, they killed Slack with DNS
- Adoptium still hasn't managed to provide repositories after fucking up it's transition from AdoptOpenJDK
- No, a project with JDK 8 makes no sense anymore, take that shit and burn it. JDK 11 the same, would be great if we had a Repository working for JDK 17 Adoptium....
- unwanking a TLS setup by integrating an intermediary load balancer to deal with several outdated TLS implementation is a kind of thing that's really scary...
(TLS 1.3 in, TLS 1.1 - TLS 1.3 out... Theoretically all solutions have TLS 1.2… most of them non working. Solutions is a wild bunch from different vendors)
- If you buy a fucking new Apple with an Arm Chipset, ram it up so far up your arse it gets dissolved in stomach acid.
It's an arm. There's tons of compatibility problems of course. No you shouldn't listen to what the marketing says. No I cannot shit rainbows and make it work.
- German election. No politics I know, but still.
- New neighbors decided to move in. Friendly person's. Except I wanted to murder them since they choose 22 o clock for moving time.
- I forgot putting the heater on. Ever woken up frozen like fuck and having a hard week... It's a good combo to break any form of motivation.
The company next to me is renovating. Waking up to the feeling of an earth quake because they demolish their old building is another thing that makes me unhappy.
It's Friday. I survived.17 -
That moment when you thought you've fortified yourself with enough RAM for the future (32GB) and Blender fails to work with a large project because...it runs out of memory (just in the loading phase, building them intermediate data structures pushes it over the edge I guess).

It was kind of fascinating to watch the memory usage indicator creep up though. Morbid fascination.3 -

GPU only displays out of 2 DP ports
and for the very first time... Have had an SSD fail...

(Best read while listening to AEnima by Tool, loudly)
Dear Current Workplace,
Fuck you, for the reasons enumerated below.
Fuck your enterprise grey blue offices, the stifling warm air of a hundreds of bodies and sub par "development laptops".
Fuck your shitty carbonated water machines which were a cost saving measure over decent drinkable water.
Fuck your fake "flexi time", "you can do home office whenever you want" bullshit. You're still inviting me to mandatory meetings at 09:00 regularly.
Fuck your shitty, in house, third part IT provider sister company. They're the worst of all worlds. If it was in company, we'd get to give out to them, if it was an external company we'd fire them. And yes, when I quit I will quote the dumpster fire that is our corporate VPN as a major factor.
Fuck your cheery, bland, enterprise communication. Words coming under the corporate letterhead seem to lose all association with meaning. Agile, communication, open are things you write and profess to respect, but it seems your totally lack understanding of their meaning.
Fuck your client driven development. Sometime you actually have to fix the foundations before you can actually add new features. And fuck you management who keep on asking "why are there so many bugs and why is it always taking longer to deliver new releases". Because of you, you fucknuts, Because you can't say "NO" to the customer. Because you never listen to your own experienced developers.
Fuck your bullshit "code quality is important to us" line. If it's so important, then let us fix the heap of shit you're selling so that it works like a quasi functional program.
Fuck you development environment which has 250 projects in a single VS solution. Which takes 5mins plus to compile on a quad core i7 with 32 gb of ram.
Fuck this bullshit ball of mud "architecture". I spend most of my time trying to figure out where the logic should go and the rest of the time writing converters between different components. All because 7 years ago some idiot "architect" made a decision that they didn't have to live with.
Actually, fuck that guy in particular. Yeah, that guy who was the responsible architect for the project for 4 years and not once opened the solution to look a the code.
Fuck the manual testing of every business process. Manual setup of the entities takes 10mins plus and then when you run, boom either no message or some bullshit error code.
Fuck the antiquated technology choices which cause loads of bugs and slow down development. Fuck you for forcing me to do manual tests of another developers code at 20:00 on a Friday night because we can't get our act together to do this automatically.
Fuck you for making sure it's very clear I'm never going to be anything but a code monkey in this structure. Managers are brought in from outside.
Fuck you for being surprised that it's hard to hire competent developers in this second rate, overpriced town. It's hard to hire anywhere but this bland shithole would have anyone with half a clue running away at top speed.
Fuck you for valuing long hours and loyalty over actual performance. That one guy who everyone hated and was totally incompetent couldn't even get himself fired. He had to quit.
Fuck you for your mediocrity.
Fuck you for being the only employer for my skill-set in the region; paying just well enough that changing jobs locally doesn't make sense, but badly enough that it's difficult to move.
Fuck you for being the stable "safe" option so that any move is "risky".
Fuck your mediocrity.
Fuck you for being something I think about when I'm not at work. Not only is it shit from 9 to 5 you manage to suck the joy out of everything else in my life as well?
Fuck you for making me feel like a worse developer every day I work here. Fuck you for making every day feel like a personal and professional failure. Fuck you for making me seriously leave a career I love for something, anything else.
Fuck you for making the most I can hope for when I get up in the morning is to just make it until the night.6 -
I've been lurking for a while but I had it up to here with these goddamned "js sucks" posts.
I'm not gonna deny js has severe design problems,
or that chromium is a motherfucking vampire
or that it's a goddamn pain in the ass to understand how to babel webpack + plugins correctly
that is all true.
the problem is that it's just a lazy damn circlejerk at this point where no learning is gained, with no outlook on any possible solution of these problems, let alone ANY type of actual collaboration to help the situation.
sometimes people don't even care to specify what is specifically wrong with js. It's just "js sucks" and that's it, farm ++.
slack is a ram hog, yes, yes, we know... WE KNOW.
every 5 days someone has to remind that!
is there any solution? why is it a ram hog? is electron the problem, or is the slack source code doing weird shit?
are there any lightweight alternatives to electron?
That's actual good conversation, but no, apparently it's impossible to drop the snarky tone for 2 seconds.
I think it's fine to point out defficiencies in applications, but it's not ok to shitpost on and on.
I would very ok with someone shitcomplaining about js is if they were doing something about it.
I'm still ok with people letting of some steam, I'm fine with people expressing frustration from direct work experience with js. I'm not ok with people and their ignorance and snarky comments and non helpfulness while comfortably laughing from their own camp of totally unrelated technologies.
Hearing sysadmins or people that code exclusively in c shit on js makes me feel my insides twirl.
Imagine I didn't do shit for linux, but I went around forums pointing out the defficiencies, like the lack of standards, and saying that mac is way better.
Or I if yapped on and on about openvpn and having an obscure as fuck api, meanwhile not doing a single fucking thing about it, or not even using it in a day to day basis.
do you hate slack's ram usage? me too and js isn't going anywhere in the next 5 years, so either do something or provide smart conversation, diagnosis of the problem or possible alternstives/solutions, otherwise stfu12 -
Hello devRant, a question for you.
I'm looking to redisign/setup my server 'infrastructure'.
It'll exist out of:
7 vps's (6+gb ram/500gb+/100mbs up/down per vps)
2 dedicated servers running as virtualization servers. (16gb/4tb/1gbit up/down and another one but let's leave that one out for now because it's gonna take a shit ton of time to solve that clusterfuck)
One server will function as an entry point for all websites I run, multiple database servers and multiple backup ones.
Any advices/tips/ideas?
Just a very serious hobby thing :)18 -
Dev: Hi Guys, we've noticed on crashlytics that one of your screens has a small crash. Can you look?
Me: Ok we had a look, and it looks to us to be a memory leak issue on most of the other screens. Homepage, Search, Product page etc. all seem to have sizeable memory leaks. We have a few crashes on our screens saying iPhone 11's (which have 4gb of ram) are crashing with only 1% of ram left.
What we think is happening is that we have weak references to avoid circular dependencies. Our weak references are most likely the only things the system would be able to free up, resulting in our UI not being able to contact the controller, breaking everything. Because of the custom libraries you built that we have to use, we can't really catch this.
Theres not really a lot we can do. We are following apples recommendations to avoid circular dependencies and memory leaks. The instruments say our screens are behaving fine. I think you guys will have to fix the leaks. Sorry.
Dev 1: hhhmm, what if you create a circular dependency? Then the UI won't loose any of the data.
Dev 2: Have you tried looking at our analytics to understand how the user is getting to your screens?
=================================
I've been sitting here for 15 minutes trying to figure out how to respond before they come online. I am fucking horrified by those responses to "every one of your screens have memory leaks"2 -
I bumped into my PC early this morning, and it took me 12 hours to realize that 3 out of 4 RAM sticks were chilling on top of my graphics card... together with the CPU cooler.
I'm not sure whether I should be amazed that it kept running (with a few random reboots) with just a crusty chunk of thermal paste as a cooling block, or worried about how fried my hardware is now.12 -
One of those things that put a smile on my face happened today.
I (like many devs) am fond of Linux. So I use Linux on everything.
I'm currently doing an internship abroad in Finland(Linus Torvald's country!) for my college.
So there is this Finnish student who uses Linux. And after a while he asked what I was using so I told him that I'm running linux(arch+i3 like all the cool kids).
So one day he was like; But can you game on Linux?
I was like, yeah sure, might not work as well as Windows but some games run native and some can be emulated through wine. He was like; Hmm maybe I'll try it out.
So he installed Linux mint on his laptop and came to work. I was rather proud (even though he installed the bastard child of Debian and Ubuntu).
So far I've helped him set up streaming games from his pc to Linux and port forwarding.
But then came the big boy. Since I always try to teach him some stuff since they don't teach him a lot at his school.
He asked me if I could help him set up a plex streaming server on Linux.
So we took an old computer and installed Ubuntu Server(Lot's of information for it).
Installed and configured plex server, qtbittorrent-knox and all kind of goodies.
I started showing him how to use ssh, how the rights system works, etc.
It broke my heart a little that he want to be able to teamviewer in it.(since it's running openSSH daemon)
So he installed Ubuntu's desktop ontop of it as well as teamviewer.
It ran slow as hell because the PC has an old crummy core2duo and ddr2 2gb of ram. It chokes when multitasking.
So seeing that as well as telling him everything that can be done with a GUI can be done in CLI.
I saw the lightbulb lighting up. He gets it now. He understand the power of Linux.
That just made me smile all the way home.1 -
So, today for my SO's father who is already over 70 and wants to try Linux. However, he doesn't want Linux on his main PC for now, rather on the old one so that he can take his time to get familiar, which is a reasonable plan.
But holy crap, what a machine! Intel Core2 Duo 4400, 2 GB DDR2(!) RAM, 250 GB IDE(!) HDD, DVD RW drive. Graphics, sound and LAN integrated on the mobo chipset. It's half a miracle that it doesn't run on steam. The machine had been delivered with Vista and has always been painfully slow.
It doesn't even support booting from USB, but I had prepared a DVD just in case. Surprise: it booted from DVD without issues and with full HW support!
Partitioned and installed, deleted Vista in the process (felt good). I went with the full blown Mint 20 Cinnamon edition because XFCE isn't as beautiful. Also, having XFCE now and then Cinnamon looking different on the other PC would be confusing.
Installation took some time, but worked. Cinnamon's RAM usage is at 750 MB idle, and at 1.1 GB with Firefox started. Once the PC is booted, it runs pretty OK with reduced swappiness and noatime on all file systems, plus unnecessary startup applications disabled. Updates took long, but ran through successfully. Installed LibreOffice and some small games, Firefox got uBlock Origin, Youtube worked OOTB.
That PC somehow had escaped disposal several times - and now has a proper OS for the first time in its miserable existence. It runs so much better than it ever has. Just wow, a "big" Linux desktop from 2020 blows a contemporary Vista out of the water on such an old machine!16 -
Went back to KDE over the weekend from i3wm. I was getting tired of having to configure my setup manually everytime I wanted to change a setting, and having things break, and having to bug fix said breaks, while also trying to handle Java MVC and node.js dev work.
Nope. Too much. I want the macOS experience but with the control of Linux. Much happier with KDE. It does use about 720MB more RAM on an average session but when you have 8GB does it really matter?
Now to figure out how to get Firefox to play nice with Plasma, or give Konqueror a spin.15 -
Does anyone here code on a machine with 64GB of RAM? I'm tired if running out of RAM but 64 is probably overkill.32

Well, for starters there was a cron to restart the webserver every morning.
The product was 10+ years old and written in PHP 5.3 at the time.
Another cron was running every 15 minutes, to "correct" data in the DB. Just regular data, not from an import or something.
Gotta have one of those self-healing systems I guess.
Yet another cron (there where lots) did run everyday from 02:00 to 4ish to generate the newest xlsx report. Almost took out the entire thing every time. MySQL 100%. CPU? Yes. RAM? You bet.
Lucky I wasn't too much involved at the time. But man, that thing was the definition of legacy.
Fun fact: every request was performed twice! First request gave the already logged-in client an unique access-token. Second request then processed the request with the (just issued) access-token; which was then discarded. Security I guess.
I don't know why it was build this way. It just was. I didn't ask. I didn't wanted to know. Some things are better left undisturbed. Just don't anger the machine. I became superstitious for a while. I think, in the end, it help a bit: It feels like communicating with an alien monster but all you have is a trumpet and chewing gum. Gentle does it.
Oh and "Sencha Extjs 3" almost gave me PTSD lol (it's an ancient JS framework). Followed by SOAPs WSDL cache. And a million other things.5 -
Had nothing to do today, so I thought I´ll test the migration of SVN to Git in Gitlab.
Boss sent me a mail today, that when I migrate we need to preserve the history, so I actually have to put some effort in it. *sigh*
Shout-out to the Gitlab documentation at this point.
That´s probably the best doc I´v ever read...
Well so I tried to use svn2git. And well...
Who the fuck thought that this piece of shit software is in any way usable?
Holy crap!
If it fails, it just does so without any info why. Even in verbose mode.
And the RAM usage? What the actual fuck?
This whole thing is a complete memory leak!
32Gigs of RAM full in Minutes and the whole system starts to stall!
And then when I thought it finally runs through.
Bam another git checkout error...
Googling for that error then I found something. A version of svn2git made in .Net Core.
Didn´t expect much but I tried it anyways.
And would you look at that!
It ran so smooth and didn´t need that much RAM , I had some doubt it did work correctly.
But it did!
I think I´m gonna pay a coffee or two to some guy over in China now!6 -
I've just revived an old desktop computer today. Turns out that it was running Windows XP, Avast free antivirus, and had Bearshare as a default search engine (in other words, that thing is NOT going to be connected to my network).
But, it also had Chrome installed. So I thought to myself, with 1.25GB of RAM, there's no way that it could run Chrome smoothly. Opened it, and....
It consumed 80MB of RAM. 80 MEGABYTES. And that's not even a clean installation of it, it's a (likely) malware-infested one from a user! Compare that to the Chrome of today.21 -
Fuck it. It's Friday EOD.
Enough is enough.
It's time to close my lappy and go for a nice long stroll, get all those work thoughts out of my RAM and get ready for two whole days of slacking!!!!
See you next week, suckers!5 -
Can ppl stop bitching out about their ides not running smoothly with 8gb+ ram? I mean 8gb ram wise is enough, unless you have 20+ browser tabs open, watching some casual porn, downloading some more porn in the background and maybe running some benchmarks just for the sake of not letting your dollars go to waste...15

I fuckin love i3wm.
Especially on laptops. Not having to carry mouse around and being it so light, which saves you a lot of battery alongside with cpu/ram makes me wanna cry out of joy.1 -
This isn't as much of a rant as the story of my worst abuse of computer knowledge.
This happened a couple years ago. When I was in high school, I had this friend/enemy relationship with this guy, lets call him Thomas. He loved to pull pranks on people. He had a similar firend/enemy relationship with my brother, and after one prank, my brother decided to get revenge. And by revenge, he meant asking me to make a virus.
I knew the guy, and I agreed. We thought about what type of virus we could make that would be funny, and not too damaging. We decided on a program that would play annoying sound effects every few minutes. Short enough to be noticable, long enough that Thomas would give up and not try to investigate.
I won't bore you with the details of the program. It was a very simple C app, very small, named "Counter-Strike-Global-Offence-Free-Download-Totally-Legit.exe". It was clearly visible in task manager, but since it was so small and barely used CPU or RAM it would stay near the bottom. I tried loading a custom sound effect, but it turned out the windows default "invalid sound effect" was much more annoying than any custom sound I could find.
The "Infecting" portion consisted of moving the .exe to the start menu startup folder while Thomas left his laptop unattended. My brother handled this part.
I unfortunaly left the country soon after and never actually saw the effect the program had on Thomas. I assumed my brothers laughing would give it away rather fast and he could simply remove it from his startup folder. However, my brother told me he still complained about it for months, before finally bringing the laptop to a repair center that found the totally legit CS:GO exe. My brother ended up telling him soon after, but this was still the best prank I ever pulled. -
So, I decided to post this based on @Morningstar's conundrum.
I'm dissatisfied with the laptop market.
Why THE FUCK should I have to buy a gaming laptop with a GTX 1070 or 1080 to get a decent amount of RAM and a fucking great processor?
I don't game. I program. I don't even own a fucking Steam library, for clarification. Never have I ever bought a game on Steam. Disproving the notion that I might have a games library out of the way, I run Linux. Antergos (Arch-based) is my daily driver.
So, in 2017 I went on a laptop hunt. I wanted something with decent specs. Ultimately ended up going with the system76 Galago Pro (which I love the form factor of, it's nice as hell and people recognize the brand for some fucking reason). Matter of fact, one of my profs wanted to know how I accessed our LMS (Blackboard) and I showed him Chromium....his mind was blown: "Ir's not just text!"
That aside, why the fuck are Dell and system76 the only ones with decent portables geared towards developers? I hate the prospect of having to buy some clunky-ass Republic of Gamers piece of shit just to have some sort of decent development machine...
This is a notice to OEMs: yall need to quit making shit hardware and gaming hardware with no mid-range compromise. Shit hardware is defined as the "It runs Excel and that's all the consumer needs" and gaming hardware is "Let's put fucking everything in there - including a decent processor, RAM, and a GTX/Radeon card."
Mid-range that is true - good hardware that handles video editing and other CPU/RAM-intensive tasks and compiling and whatnot but NOT graphics-intensive shit like gaming - is hard to come by. Dell offers my definition of "mid-range" through Sputnik's Ubuntu-powered XPS models and what have you, and system76 has a couple of models that I more or less wish I had money for but don't.
TBH I don't give two fucks about the desktop market. That's a non-issue because I can apply the logic that if you want something done right, do it yourself: I can build a desktop. But not a laptop - at least not in a feasible way.23 -
The Cloud Of Bullshit
Every day I wake, and I think of my one true mission in life. To mock and ridicule paint huffing idiots. Something recently that drew my ire, like the hemorrhoids on my ass is this idea of 'the cloud', THE CLOUD and the buzzword lingo-bingo bullshit that providers use to hype and sell it.
For example, airtable is an amazing service. I love that I can insert just about anything into a row, create any of my own row datatypes, that it's flexible as all hell.
I love it.
And I hate that I'm essentially locked in to the cloud.
I fucking hate how if my internet goes down (thanks you pie eating inbred dipshits at comcast) I have no access.
If the company is bought, they'll shut down like all the rest , to be "relaunched at a later time" (or never).
I hate that if the company doesn't make enough money, or it's investors change their mind, woopsie, service is shut down.
I hate that the cloud is synonymous with massive data leaks and IOT-levels of stupidity in security practices.
Every time someone says "but its in the cloud! Isn't it amazing!"
I always think 1. YEAH IF IM AN INVESTOR I GET TO MILK LOW BROW FINGER PAINTING FUCKWITS EVERY MONTH like Adobe sucking the blood from infants who are still in college.
2. Why? So I can get locked into their platform, have them segment off previously free features (fucking youtube and the 'subscribe so you can continue playing audio with your screen off' bullshit), and then have fees increase month over month?
3. Why, so every four years during the presidential selection, if I piss off some fuckstick braindead lemming literally sucking his girlfriends BFs cock, they can potentially shut me out from my own data completely?
The Cloud is built on shit-colored hype sold to knob gobbling idiots, controlling idiots, profiting at the expense of idiots, and later fucking them for buyout payola. The Cloud is a Cloud of Bullshit shat out by huckster messiahs straight into the lapping mouths of fanatics worshiping slavishly like toilet drinking scum at the porcelain alter of a neon god, invisible, untouchable, and like a spigot, easily shut off without anyone noticing. And when it happens, I'll be there, shouting "WHERE IS YOUR CLOUD NOW?"
Native any day. 100% native or I don't fucking want it
None of this node.js-gone-native bullshit either with notetaking apps taking up hundreds of megabytes of ram, where everything is bootstrap or react, in a browser, in a window container, because people are so fucking incompetent we have to hold their hand WHILE they give themselves a reach around.
Native or nothing.
For my favorite notetaking app, I use Microsoft OneNote. "OH god, a heathen, quick, stick his body up on a stake!"
But hear me out. I'll be the first one in a crowd to kick bill gates in the nuts (not because I particularly hate microsoft, just because I think hes kind of a cunt).
So when I say onenote is good, I really fucking mean it. Sure they did some cunty things like 'dumbed down' the interface, and cut out some options. But you know what they can't do?
Shut down the damn service (short of a system update completely removing the whole app, which, frankly, wouldn't surprise me).
It's so god damn good it waxed my balls, cured my cancer, fixed my relationship with my father, found my long lost brother, and replaced ALL my irl notebooks.
It's so good that if it was cocaine I'd be hospitalized for overusing it.
So god damn good it didn't just replace all my notebooks, it even replaced and sped up my mockup process three to five times. Want layers?
Built in. Just drag an image on to the notebook to import instantly.
Want to rearrange layers? Right click select "send forward/back/bring to front/send to back".
Everything snaps to grid by default and is easily resizeable.
I had all the elements for a UI sliced and diced. Wanted to try a bunch of layouts. Was gonna take me two damn days.
Did it in three hours with the notebook features of onenote.
After I started using onenote, me and my bodypillow finally conceived even.
Sweet marries mammaries I just fucking jizzed. Thank you onenote.
P.s. It really did speed up my UI design, allows annotated images, highlighted text. Shit, it can even do kanban.
And all I can think is "good job microsoft making an awesome product for free, being dumb as fuck for not charging for it, and then not marketing it at ALL."
It was sheer fucking luck that I discovered it while was I was looking for vendor STD bloatware to blast off my new install.
OneNote: Worth a try even for the kick-gates-in-the-nuts fan club.
The cloud can suck my balls.18 -
Swithced to Ubuntu, this is my first ever OS outside of windows. Man I am loving this shit.
Bought my laptop with windows 8, was working like charm and then came windows 10, I updated it and it was working fine untill they started releasing the patch updates. My laptop became slow as fuck, taking forever to boot and bitch was I afraid to connect to my wifi fearing the background data consumption and the antivirus clogging the ram.
I am free now, I am finally free. I am ready suck the developer's dick just to please him for this masterpiece and helping me get out of this misery.19 -
Let me just get right down to it.
FUCK YOU Hewlett-fucking-Packard FOR YOUR SHITTY LAPTOPS! Don't you even keep your customer's needs in mind when you design these things? Besides all the bloatware you stuff into the Windows you ship it with, at least make the quality of your shit better. These flimsy screens and loose hinges, I've had to get that shit replaced multiple times in just the past year.
Want to upgrade to an SSD or plug in more RAM? Guess what! I've to tear the whole thing apart! Keyboard, palm rest, all if it! What even happened to just popping a cover at the bottom to swap out the hard drive!? I have to fucking congratulate you, you fucking cunts, for making an easy process as difficult as it can fuckin possibly get. You guys deserve an award for this, preferably presented to you, shoved up your asses.10 -
Fucking shit, this university's website is so damn slow! Basically Every Semester, every student need to enroll to certain classes in University Website.
But the Infrastructure is not enough to handle such a big amount of students, we have approx. 7000 students enrolling at the same fucking time.
And here i am can't enroll to any class at all this semester. Fuck such a waste of time. This always been a thing since they digitalize enrolling system.
I don't want this to happen again. The student always be a victim since they cannot handle the request. Now, as a dev, i want to propose something better to optimize the server, i have some connection to pass some bureaucracy. I am going to do some brainstorming and I will need some solution.
Here some data i gather when i am mad from my univ infrastructure division :
1. The Server is a simple Local Server Forwarded to the Internet.
2. The Server use Windows Server 2007.
4. Web Server Using Microsoft IIS
3. The Website built using ASP.NET
4. The connection is not SSL encrypted (yes its fucking use the http)
5. Hardware Spec (not confirmed officialy, i got this information from my professor) :
- Core i5 4460
- 4 GB Ram
- 1 Gbit NIC
I will summon some expert here and i hope want to help me(us all) out.24 -
I spent the last three weeks+ (literally THREE full weeks, weekends too) building something I thought was really cool, powerful, and useful. Made a blog post, posted a giant thread on the company Twitter.
Literally one person gave it a like.
I don't know why I give shit anymore, cuz nowadays if it isn't about getting rich quick, cHaTgPt, or some other made up hype, no one cares. Apparently I shouldn't either...
Meanwhile my 16 GIGABYTE RAM MAC, yes 16 GIGABYTE RAM can't even hold power while plugged in, and I'm still clowning around with an ancient iPhone 6 (actually one of my mom's old iphones) that barely stays above 20% battery for more than an hour...
And FINALLY, my FUCKING ISP is for sure screwing me, since I've been doing some hard core data streaming and broadcasting, even though I pay $60+ month for that shit it, keeps dropping out, shit doesn't load.... I mean wtf this isn't 1990 dialup AOL anymore
When I step back I just feel like the worlds biggest loser, maybe the world's biggest 🤡7 -
Set out to copy the iOS alarm on android because a) android's stock alarm is fugly and b) all other sleep reminder apps either offer me way too much or no functionality.
Week 1: "Oh, custom UIs need a lot of math... Ok."
Week 2 "Why on earth is my ram usage at 400 mb?!"
Week 6: "I have come to the realisation that android's ByteArrayDecoder should burn in hell.
Week 7: "Man... They sure made the management of intents and pending intents a pain."
Week 10: There. It works. Two classes, 7000 lines of code.... Hmmmm maybe apply MVP."
Week 11: I discovered embarrassment driven development, throw away all my code and start from scratch.
Week 12: Oh ButterKnife, where have you been all my life?
Week 17: I might actually finish this in my life time!
Week 28: Man, this MVP and managing Context, intents, SQLITE DB and pending intents do not mix well.
Week 46: I discover RxJava and Dagger 2
Week 47: I discover that the 'V' in MVP does not refer to an 'Activity'
Week 48: My StudyBudy says to me "Man, exams are only a month away!"
Week 49: I put all your code in my github, delete it locally and focus back on being a student.2 -
Felt like a real badass in middle school when I made my first .bat script that would recursively open itself. Took only two words. Four if you wanted exponential recursion rather than linear. And I came up with it by myself.
Cheesiest thing ever, but I really loved freaking people out by opening it and just watch windows grind to a halt as it would run out of ram opening thousands of terminal windows. Hell, it still gives me a kick today when I show it to people the first time :D7 -
I had spent the last year working on a online store power by woocommerce with over 100k products from various suppliers. This online store utilized a custom API that would take the various formats that suppliers offer their inventory in and made them consistent. Now everything was going swimmingly initially, but then I began adding more and more products using a plug-in called WP all import. I reached around 100k products and the site would take up to an entire minute to load sometimes timing out. I got desperate so I installed several caching plugins, but to no avail this did not help me. The site was originally only supposed to take three to four months but ended up taking an entire year. Then, just yesterday I found out what went wrong and why this woocommerce website with all of these optimizations was still taking anywhere from 60 to 90 seconds to load, or just timing out entirely. I had initially thought that I needed a beefier server so I moved it to a high CPU digitalocean VM. While this did help a little bit, the site was still very slow and now I had very high CPU usage RAM usage and high disk IO. I was seriously stumped the Apache process was using a high amount of CPU and IO along with MYSQL as well. It wasn't until I started digging deeper into the database that I actually found out what the issue was. As I was loading the site I would run 'show process list' in the SQL terminal, I began to notice a very significant load time for one of the tables, so I went to go and check it out. What I did was I ran a select all query on that particular table just to see how full it was and SQL returned a error saying that I had exceeded the maximum packet size. So I was like okay what the fuck...
So I exited my SQL and re-entered it this time with a higher packet size. I ran a query that would count how many rows were in this particular table and the number came out to being in the millions. I was surprised, and what's worse is that this table belong to a plugin that I had attempted to use early in the development process to cache the site. The plugin was deactivated but apparently it had left PHP files within the wp content directory outside of the actual plugin directory, so it's still executing scripts even though the plugin itself was disabled. Basically every time I would change anything on the site, it would recache the whole thing, and it didn't delete any old records. So 100k+ products caching on saves with no garbage collection... You do the math, it's gonna be a heavy ass database. Not only that but it was serialized data, so when it did pull this metric shit ton of spaghetti from the database, PHP then had to deserialize it. Hence the high ass CPU load. I had caching enabled on the MySQL end of things so that ate the ram. I was really desperate to get this thing running.
Honest to God the main reason why this website took so long was because the load times made it miserable to work on. I just thought that the hardware that I had the site on was inadequate. I had initially started the development on a small Linux VM which apparently wasn't enough, which is why I moved it to digitalocean which also seemed to not be enough, so from there I moved to a dedicated server which still didn't seem to be enough. I was probably a few more 60-second wait times or timeouts from recommending a server cluster to my client who I know would not be willing to purchase it. The client who I promised this site to have completed in 3 months and has waited a year. Seriously, I would tell people the struggles that I would go through with this particular site and they would just tell me to just drop the site; just take the money, just take the loss. I refused to, this was really the only thing that was kicking my ass. I present myself as this high-and-mighty developer like I'm just really good at what I do but then I have this WordPress site that's just beating the shit out of me for a year. It was a very big learning experience and it was also very humbling as well, it made me realize that I really don't know as much as I think I might. It was evidence that there is still so much more to learn out there, I did learn a lot from that experience especially about optimizing websites the different types of methods to do that particular lonely on the server side and I'll be able to utilize this knowledge in the future.
I guess the moral of the story is, never really give up. Ultimately things might get so bad that you're running on hopes and dreams. Those experiences are generally the most humbling. Now I can finally present the site that I am basically a year late on to the client who will be so happy that I did not give up on the project entirely. I'll have experienced this feeling of pure euphoria, and help the small business significantly grow their revenue. Helping others is very fulfilling for me, even at my own expense.
Anyways, gonna stop ranting. Running out of characters. If you're still here... Ty for reading :')7 -
I've got a rant-type question:
Why would you EVER use Google Chrome?
There are a million browsers in the world, you could've used Firefox, Opera, Vivaldi, Brave, Bad Wolf, Qute, st, Epiphany etc, but you chose to uss Google Chrome.
What would be the reason you would ever choose Google Chrome over any of the million browsers, out of which many of them get the job done much better than Chrome? Okay, I get it why you might use IE or Edge, cause you might be too lazy to install any other browser or you just want the performance benefits you get with Edge which totally, most definatelly, a very big plus point for Edge.
*"Chrome has a balanced-bloat out of all browsers"*
But how tf does that matter? That doesn't even help performance wise anyways.
I can't get over the fact that I have to see/hear about 'Chrome hogging RAM' EVERYWHERE. Like, why do you even care about the god damn browser? Why is it a standard over the million other browsers that exist? Why can't the general public be educated that browsers have choices (just like phones) and you don't have to spit crap over people who don't use Chrome.
It just drives me crazy of how many people hate Chrome, and still it's a 'default' browser.
I would quote Vivaldi (the company/browser):
'A browser should adapt to you, not the other way around.'
(Disclaimer: Rant of a former Firefox, qute, st, Opera, OperaGX, Edge, and ofcourse, Chrome user. Currently in deep love with Vivaldi.)
I'm done ranting. Have a nice day!
(My first post here, if I did something wrong, let me know! I'll make sure I don't do it again!)55 -
Just found out about Yue, a GUI library for Node.js, Lua and C++ (and owners of the "gui" package on npm).
It is so awesome! The RAM usage is so low compared to Electron! Of course it has its limitations and doesn't use HTML + CSS + JavaScript, but you can still build really good applications with it!
I'll show you what I'm making at the moment soon, so stay tuned!
Anyways I've built the same application in Electron and Yue, here's the comparison of the RAM usage:16 -
After a few weeks of being insanely busy, I decided to log onto Steam and maybe relax with a few people and play some games. I enjoy playing a few sandbox games and do freelance development for those games (Anywhere from a simple script to a full on server setup) on the side. It just so happened that I had an 'urgent' request from one of my old staff member from an old community I use to own. This staff member decided to run his own community after I sold mine off since I didn't have the passion anymore to deal with the community on a daily basis.
O: Owner (Former staff member/friend)
D: Other Dev
O: Hey, I need urgent help man! Got a few things developed for my server, and now the server won't stay stable and crashes randomly. I really need help, my developer can't figure it out.
Me: Uhm, sure. Just remember, if it's small I'll do it for free since you're an old friend, but if it's a bigger issue or needs a full recode or whatever, you're gonna have to pay. Another option is, I tell you what's wrong and you can have your developer fix it.
O: Sounds good, I'll give you owner access to everything so you can check it out.
Me: Sounds good
*An hour passes by*
O: Sorry it took so long, had to deal with some crap. *Insert credentials, etc*
Me: Ok, give me a few minutes to do some basic tests. What was that new feature or whatever you added?
O: *Explains long feature, and where it's located*
Me: *Begins to review the files* *Internal rage wondering what fucking developer could code such trash* *Tests a few methods, and watches CPU/RAM and an internal graph for usage*
Me: Who coded this module?
O: My developer.
Me: *Calm tone, with a mix of some anger* So, you know what, I'm just gonna do some simple math for ya. You're running 33 ticks a second for the server, with an average of about 40ish players. 33x60 = 1980 cycles a minute, now lets times that by the 40 players on average, you have 79,200 cycles per minute or nearly 4.8 fucking cycles an hour (If you maxed the server at 64 players, it's going to run an amazing fucking 7.6 million cycles an hour, like holy fuck). You're also running a MySQLite query every cycle while transferring useless data to the server, you're clusterfucking the server and overloading it for no fucking reason and that's why you're crashing it. Another question, who the fuck wrote the security of this? I can literally send commands to the server with this insecure method and delete all of your files... If you actually want your fucking server stable and secure, I'm gonna have to recode this entire module to reduce your developer's clusterfuck of 4.8 million cycles to about 400 every hour... it's gonna be $50.
D: *Angered* You're wrong, this is the best way to do it, I did stress testing! *Insert other defensive comments* You're just a shitty developer (This one got me)
Me: *Calm* You're calling me a shitty developer? You're the person that doesn't understand a timer, I get that you're new to this world, but reading the wiki or even using the game's forums would've ripped this code to shreds and you to shreds. You're not even a developer, cause most of this is so disorganized it looks like you copy and pasted it. *Get's angered here and starts some light screaming* You're wasting CPU usage, the game can't use more than 1 physical core, and after a quick test, you're stupid 'amazing' module is using about 40% of the CPU. You need to fucking realize the 40ish average players, use less than this... THEY SHOULD BE MORE INTENSIVE THAN YOUR CODE, NOT THE OPPOSITE.
O: Hey don't be rude to Venom, he's an amazing coder. You're still new, you don't know as much as him. Ok, I'll pay you the money to get it recoded.
Me: Sounds good. *Angered tone* Also you developer boy, learn to listen to feedback and maybe learn to improve your shitty code. Cause you'll never go anywhere if you don't even understand who bad this garbage is, and that you can't even use the fucking wiki for this game. The only fucking way you're gonna improve is to use some of my suggestions.
D: *Leaves call without saying anything*
TL;DR: Shitty developer ran some shitty XP system code for a game nearly 4.8 million times an hour (average) or just above 7.6 million times an hour (if maxed), plus running MySQLite when it could've been done within about like 400 an hour at max. Tried calling me a shitty developer, and got sorta yelled at while I was trying to keep calm.
Still pissed he tried calling me a shitty developer... -
We had a blind auction at work. Selling off 'redundant hardware'
Most of it was old crap but a bit a couple of bids in for shits and giggles. Also, I'm a desktop man but we have rolling blackouts so an older laptop for the simple sake of having something bigger than my phone to browse definitely has some appeal.
So there was an old HP Elitebook 8540W. A chonky boi if ever I did see one.
Spec sheet as listed
4GB DDR3
i7 M 640 @ 2.80 Ghz
128GB SSD
Win 10 Pro
"not booting up/ power button flashing"
So bid R100. Now for context, a petrol is R22 a liter. A Big Mac is R43, a Big Mac meal is R90
So basically I big so I could harvest the SSD. And I won.
Much to my surprise, I simply attached the correct charger and it boots fine. The drive was empty though but that's fine cause I was gonna chuck Ubuntu on it anyway. Also found it was in fact 8GB of RAM. It also has a blu ray drive
So in summary, for the price of 1.1 Big Macs I got:
Full 1080p 15.6"
128GB Samsung SSD
8GB ram
First gen i7
Blu ray player
I'm most not sad about the 900x that I bid on as well. It was a cute little thing, my plan was to steal the ram and ssd out of this thing and put it in that, then boom ultra portable little machine for R400. Oh I also got an old monitor with a feint line down the screen for a grand total of R18 -
Problems with redis... timeout everywhere...
30k READs per minute.
Me : Ok, How much ram are we actually using in redis ?
Metrics : Average : 30 MB
Me ; 30 MB, sure ? not 30 GB ?
Metrics : Nop, 30 MB
Me : fuck you redis then, hey memory cache, are you there ?
Memory cache : Yep, but only for one instance.
Me ok. So from now on you Memory cache is used, and you redis, you just publish messages when key should be delete. Works for you two ?
Memeory cache and redis : Yep, but nothing out of box exists
Me : Fine... I'll code it my selkf witj blackjack and hookers.
Redis : Why do I exist ?2 -
So I have a script that runs every time I turn on my PC. The script copies a few files to a ftp server in my basement. Forgot to turn off logging....
Opend the file in Notepad, and would you look at that, 1 GB of ram..? WTF?
Edit: Managed to open the file, turns out that it's been exactly one year since I started using the script.3 -
I think I finally found a reason to have a phone with 8GB of RAM.
So that when TWRP craps out on data decryption and decides not even to ask for a password, at least I can push a whole fucking ROM into RAM to unfuck the phone. Because why not?! Why on Earth would software work properly when you can just throw more hardware at it?
Long live FBE, TWRP what craps out on it, and you remember those things.. SD cards for data storage? I could've used an unencrypted SD card so fucking badly right now, you know... Long live soldered in storage that's encrypted, "for security". Except for when the person who owns said data actually wants to use the bloody data.
FUCK!2 -
La me working on a new chrome extension:
- ok, this page has some hidden divs, I need to tell the extension to make windows scroll to the bottom while there are still elements with a hidden class
- creates a while(1) loop with a condition inside it to break if no elements with hidden class are longer there.
- happy with the code
- uploads the extension
- goes to page
- brings out developer tools
- goes to console
- clicks on extension on chrome
- right clicks the extension and then inspect
- ok here we go: la me click on button inside extension popup
- console shows some logs
- nice it's still looking.
.
.
.
- wait! Why is the page not scrolling ???
- looks at logs, WTF nothing changes in logs .....
- OMMMMG a infinite loop .... infinite loop inside chrome ....
- OMMMMMG my pc's gonna crash .
-stop please stop stop.
- wait! how do I stop this?
- tries CTRL+C ... nothing
- tries CTRL+Z ... nothing ...
.
.
.
.
Abort abort Aboooooort.
.
.
.
- Deletes extension from chrome.
-..... loop still running
- clicks on X to close Chrome.....
- not closing O_o
- Oh God, i need to do something before Chrome sucks all the RAM left.
- remembers the savior...
.
.
.
- Task Manager heeeelp me.
- opens Task manager
- chrome is consuming ~ 2 GB of RAM.
- WTF! Kills chrome.
Thanks for reading my lil adventure 😅5 -
Linker crashed while building LLVM from source AT FUCKING 97% ARE YOU FUCKING KIDDING ME?
(Antergos , GCC 7)
The error was that it exhausted the memory. How the fuck does a system with 16GB RAM and a swapfile run out of memory while building something? Dayum.5 -
Here's an issue I've been having with my PC for the past year;
*gets blue screen of death* (every 5 mins)
*takes out my second pair of ram cards, blue screening stops*
*waits a day, puts cards back in, has no more problems for 1-2 weeks*
*gets more blue screens*
*repeats*
If I leave the cards out, the system NEVER has any issues.
But, I can't play games smoothly on 4gb of ram.
Also, I can't afford new cards.18 -
imagine having kernel memory leaks in 2020
AT&T or Huawei, whichever, pushed an update for my already-struggling-to-exist phone that made the kernel memory leak go from 480KB/hr avg to 22.5MB/hr avg. When my free RAM is never under 50% of 2GB after the kernel starts loading other shit and i'm able to express free RAM, at any time in use, in megs, with 8 bits... this means my phone crashes, with no apps running aside from a trimmed list of stock apps, every 3-4 hours due to running out of RAM. The only usable (read: not R/O because unrooted) swapfile is located on a tmpfs, so it's completely fucking useless (and eats another 100MB of RAM that I could be using for LITERALLY anything else, that's like another 3 hours of full idle between crashes) and I can't unlock the bootloader to fix any of this as Huawei no longer hands out keys and it'd take 7 years or so to brute (32-bit @ 10/sec)
tl;dr: fuck15 -
Despite common sense, I think technology is not making our lives easier. It's just build chaos on top of chaos.
Take server-side programming for instance.
First you have to find someone to host your thing, or a PaaS provider. Then you have to figure out how much RAM and storage you need, which OS you're going to use. And then there's Docker (which will run on top of a VM on AWS or GCP anyway, making even less sense). And then there's the server technology: nginx, Apache (and many many more; if, that is, you're using a server at all). And then there are firewalls, proxies, SSL. And then you go back to the start, because you have to check if your hosting provider will support the OS or Docker or your server. (I smell infinite recursion here.)
Each of these moving parts come with their own can of worms in terms of configuration and security. A whole bible to read if you want to have the slightest clue about what you're doing.
And then there's the programming language to use and its accompanying frameworks. Can they replace the server technology? Should you? Will they conflict with each other and open yet another backdoor into your system? Is it supported by your hosting provider? (Did I mention an infinite recursion somewhere?)
And then there's the database. Does it have a port to the language/framework of your choosing? Why does it expose an web interface? Is it supposed to replace your server? And why are its security features optional again? (Just so I have to test both the insecure and the secure environments?)
And you haven't written a single line of code yet, mind you.4 -
Area of focus: Native iOS dev
Why: Spent years trying hybrid tools, dealing with the most ridiculous errors, bugs and issues you can begin to comprehend and then ... something magical happened. I got a book on Objective-c, learned a little, tried a simple app ... and it worked ... like properly worked, and on all the devices without taking half the RAM.
I'll say that again as I don't think it landed. In Objective-c, I got no issues where only the CEO's phone + OS version meant I couldn't load a map and a pin (looking at you titanium!!!)
In Objective-c, I wasn't promised storyboards and autolayout, only to find out they are completely different, and may god help you trying to google the issues, as the only ones to show up would be the native tools (looking at you Xamarin)
In Objective-c, my app doesn't instantly consume 125mb of RAM to load a fucking webview (looking at you ... well nearly every other hybrid tool)
... it just works. Then Swift came along and things only got better.13 -
My setup: AMD Phenom-2 1100T with fat cooler for silent PC, 16 GB ECC RAM, AMD Radeon HD-6850 passively cooled, WD Blue 1 TB HDD. One 22 inch monitor with 1650 x 1050.
The mouse is a bit broken because the click switch under the mouse wheel doesn't work anymore. The empty bottle in front of the PC is necessary for lying on the room light switch, or else it won't work. And the black/yellow tape is a fix for the worn out seat cover.
But the best, under the monitor, is the little green troll that serves as rubber duck. -

Medium long story about POP!_OS
TL;DR : A true K.I.S.S. OS. Very well designed UI. In general suitable for everyone. Any distro-hoppers MUST try out. If your current OS is already heavily customized to your needs, DON'T bother with POP. (Read till the end if you are on toilet, nothing to lose)
Backstory : I am never a fanboy of anything although I am loyal to the tools I use daily. So OS is also something I picked and use to meet my needs except when I was a student. My first linux experience was about a decade ago with ubuntu. Have tried almost all kinds of light-weight and minimal distros after that (lubuntu, arch, mint, puppylinux, fedora, centos and others I forgot) during my student years.
I like all things minimal. ("Keep It Simple Stupid" is my email signature.) When I started working, Windows became the sole OS I use since it met my needs better than others. Except that one time when I tried Elementary. Although I found it a good OS, it didn't get installed as a dual-boot. I don't find Elementary minimal. It is one of well designed OSs but I still think it can be improved. (Plus I had this weird feeling that it is similar to Mac OS)
At the start of this year, Widows alone was not enough for my needs. Decided to look for a minimal linux distro. My old i7 ASUS has 8GB RAM and roughly 250GB free storage. So I am not that worried about hardware requirements. My main struggle is downloading stuffs. (Few of you guys must know by now the speed of my internet LOL.) Well, even if I had a good speed, I will still look for minimal distro as first priority. So I went with minimal ubuntu image and xubuntu environment. Although I do not like the UI design, it is acceptable. Through out the years, I have configured it to suit my needs and currently pretty happy with it.
Thoughts on POP!_OS : To me, it is literally like meeting a young girl who is perfect for my life. She has the perfect body, beautiful face, amazing appearance and good manners. And she is young, of course there is a lack of experience issue. But it can be taught and she has a very high chance to become a wonderful lady if she continues like this. Only crap is I already have someone and in a committed relationship. So I could not go any further than introduction. I do save her contact and will keep in touch with her online. You know? Things change. Things always change somehow.2 -
So I just spent the last few hours trying to get an intro of given Wikipedia articles into my Telegram bot. It turns out that Wikipedia does have an API! But unfortunately it's born as a retard.
First I looked at https://www.mediawiki.org/wiki/API and almost thought that that was a Wikipedia article about API's. I almost skipped right over it on the search results (and it turns out that I should've). Upon opening and reading that, I found a shitload of endpoints that frankly I didn't give a shit about. Come on Wikipedia, just give me the fucking data to read out.
Ctrl-F in that page and I find a tiny little link to https://mediawiki.org/wiki/... which is basically what I needed. There's an example that.. gets the data in XML form. Because JSON is clearly too much to ask for. Are you fucking braindead Wikipedia? If my application was able to parse XML/HTML/whatevers, that would be called a browser. With all due respect but I'm not gonna embed a fucking web browser in a bot. I'll leave that to the Electron "devs" that prefer raping my RAM instead.
OK so after that I found on third-party documentation (always a good sign when that's more useful, isn't it) that it does support JSON. Retardpedia just doesn't use it by default. In fact in the example query that was a parameter that wasn't even in there. Not including something crucial like that surely is a good way to let people know the feature is there. Massive kudos to you Wikipedia.. but not really. But a parameter that was in there - for fucking CORS - that was in there by default and broke the whole goddamn thing unless I REMOVED it. Yeah because CORS is so useful in a goddamn fucking API.
So I finally get to a functioning JSON response, now all that's left is parsing it. Again, I only care about the content on the page. So I curl the endpoint and trim off the bits I don't need with jq... I was left with this monstrosity.
curl "https://en.wikipedia.org/w/api.php/...=*" | jq -r '.query.pages[0].revisions[0].slots.main.content'
Just how far can you nest your JSON Wikipedia? Are you trying to find the limits of jq or something here?!
And THEN.. as an icing on the cake, the result doesn't quite look like JSON, nor does it really look like XML, but it has elements of both. I had no idea what to make of this, especially before I had a chance to look at the exact structured output of that command above (if you just pipe into jq without arguments it's much less readable).
Then a friend of mine mentioned Wikitext. Turns out that Wikipedia's API is not only retarded, even the goddamn output is. What the fuck is Wikitext even? It's the Apple of wikis apparently. Only Wikipedia uses it.
And apparently I'm not the only one who found Wikipedia's API.. irritating to say the least. See e.g. https://utcc.utoronto.ca/~cks/...
Needless to say, my bot will not be getting Wikipedia integration at this point. I've seen enough. How about you make your API not retarded first Wikipedia? And hopefully this rant saves someone else the time required to wade through this clusterfuck.12 -
I fucking hate the Internet
day before Yesterday, I was searching for a software on internet(which is not free) I found a site (unofficial) giving me both free full & trial version. so I thought, why not get the full version. I downloaded it, installed it. awesome.
everything was going great until I found out that all of my files in a folder were encrypted by some WankDecrypt. I was lucky the files in that folder were useless. but next day some mysterious links started to pop up into my browser. and today some fucking wank decentralized shit started eating up my ram. FML
Somebody fucking stuck his shit with cracked version of software. so beware devs.13 -
My friend recently tried to install apt on fedora 🤦♂️
Some how this created a zombie process And used a ton of the ram and the ram usage leaked out of the VM and into the host server
And I had to explain to him why a package manager meant for a system with dpkg will not work on one that uses rpm12 -
Finally, I can play around with a proper server.
HP ProLiant DL380 G6 = dual 8-core Xenons @ 2.4GHz with 32GB RAM and 12TB / RAID1-0 of WD Purples (we happened to have them for some reason).
Already pissed at HP because they don't support JBOD and already pissed at myself for using CentOS, but other than that, enjoying the hell out of it!
And it's ALL MINE! ... Well, technically it's the org's, but it won't go into production for half a year and I'm the only one with the root access so, for now, it's MINE! 😅13 -
A customer brought in an older, beat-up machine and told us it wasn't booting. We noticed that his power supply was damaged, but checked it in for other diagnostics.
I found out he had a corrupted operating system, but with everything else on the computer, I didn't recommend fixing the computer.
Now, for reference, this is a Windows 7 computer with 10GB of RAM. But it also has a bent side-panel, the front-panel is hanging on by a thread, and it would also need the new power supply -- all of which would be over $200 USD.
When I finally relayed this info to him over the phone, we started talking about the system.
Him: So what do you think?
Me: I mean, this computer has some good specs, but with the damage, I wouldn't recommend repairing the computer. Now, this is your computer and you are more than welcome to tell me to shove it, but I'd recommend replacing it. We're at the breaking point of doing whatever you want to do, and it's your money that you're spending, but in my professional opinion, I don't think it's worth saving.
Him: Well, okay. I'll come in later and see what options I have6 -
My 27" 8-core imac, i7, 3.8ghz, AMD radeon pro 5500, 40 GB RAM 512 GB storage,

But never stuttered.
Never lagged.
Never glitched
Never failed
Never ran out of memory
I can just hear how hard the the ventilation was going. It was getting loud.
I touched its ass from behind. It was heated up and there was lots of dust from the holes
This has been going on for several days but i ignored it knowing what kind of a beast machine i have (big mistake)
Intellj popped up notification to disable hints in order to improve cpu usage performance.
Immediately it struck me. Hold on lemme check the activity monitor stats and find out why my imac has been screaming for days
Turns out intellj is using over 1090% of my fucking CPU?????
THAT SHIT U SEE ON THE IMAGE WENT ABOVE 1100% OF CPU USAGE AND IT WAS ONLY 1 PROCESS CAUSING IT - INTELLIJ

I bought a new laptop yesterday and just fell like superheroes at the end on movies when they find out exactly how powerful they are and what real power tastes like :D
Moving from 4gb to 8gb of RAM and a to a working battery i just bliss :)4 -
This is a guide for technology noobies who wants to buy a laptop but have no idea what the SPECS are meaning.
1. Brand
If you like Apple, and love their !sleek design, go to the nearest Apple store and tell them "I want to buy one. Recommendations?"
If you don't like Apple, well, buy anything that fits you. Read more below.
2. Size
There are 11~15 inches, weight is 850g ~ 2+kg. Very many options. Buy whatever you like.
//Fun part coming
3. CPU
This is the power of the brain.
For example,
Pentium is Elementary Schoolers
i3 is Middle Schoolers
i5 is High Schoolers
i7 is University People
Dual-core is 2 people
Quad-core is 4 people
Quiz! What is i5 Dual-core?
A) 2 High Schoolers.
Easy peasy, right?
Now if you have a smartphone and ONLY use Messaging, Phone, and Whatsapp (lol), you can buy Pentium laptops.
If not, I recommend at least i3
Also, there are numbers behind those CPU, like i3-6100
6 means 6th generaton.
If the numbers are bigger, it is the most recent generation.
Think of 6xxx as Stone age people
7xxx as Bronze age people
8xxx as Iron age people
and so one.
4. RAM
This is the size of the desk.
There are 4GB, 8GB, 16GB, 32GB, and so one.
Think of 4GB as small desk to only put one book on it.
8GB as a desk to put a laptop with a keyboard and a mouse.
16GB as a normal sized desk to put some books, laptop, and food.
32GB as a boss sized desk.
And so one.
When you do multitasking, and the desk is too small...
You don't feel comfortable right?
It is good when there are spacious space.
Same with RAM.
But when the desk becomes larger, it gets expensive, so buy the one with the affordable price.
If you watch some YouTube videos in Chrome and do some document words with Office, buy at least 8GB. 16GB is recommended.
5. HDD/SSD
You take out the stuffs such as books and laptop from the basket (HDD/SSD), and put in your desk (RAM).
There are two kinds of baskets.
The super big ones, but because it is so big, it is bulky and hard to get stuffs out of the basket. But it is cheap. (HDD)
There are a bit smaller ones but expensive compared to the HDD, it is called SSD. This basket is right next to you, and it is super easy to get stuffs out of this basket. The opening time is faster as well.
SSDs were expensive, but as times go, it gets bigger as well, and cheaper. So most laptops are SSD these days.
There are 128GB, 256GB, 512GB, and 1024GB(=1TB), and so one. You can buy what you want. Recommend 256GB for normal use.
Game guy? At least 512GB.
6. Graphics
It is the eyesight.
Most computers doesn't have dedicated graphics card, it comes with the CPU. Intel CPUs has CPU + graphics, but the graphics powered by Intel isn't that good.
But NVIDIA graphics cards are great. Recommended for gamers. But it is a bit more expensive.
So TL;DR
Buying a laptop is
- Pick the person and the person's clothes (brand and design)
- Pick the space for the person to stay (RAM, SSD/HDD)
- Pick how smart they are (CPU)
- Pick how many (Core)
- Pick the generation (6xxx, 7xxx ....)
- Pick their eyesight (graphics)
And that's pretty much it.
Super easy to buy a laptop right?

Man wk89 awesome... bringing back a lot of memories. The one thing really stands out to me though is the software.
I see a lot of rants about people shocked that turboC is still in use or other DOS programs are still in production. A lot can of bad be said here but I think often it's a case of we truly don't build things like we did in the good old days.
What those devs accomplished with such limited resources is phenomenal and the fact that we still haven't managed to replicate the feel and usability of it says a lot, not to mention just how fucking stable most of it was.
My favourite games are all DOS based, my most favourite of all time Sherlock is 103kb in size. When I started coding games I made a clone of it and to this day I am still trying to figure out what sorcery is in the algorithm that generates/solves puzzles that makes it so fast and memory efficient. I must have tried 100+ ways and can't even come close. NB! If you know you can hint but don't tell me. Solving this is a matter of personal pride.
Where those games really stand out is when you get into the graphics processing - the solutions they came up with to render sprites, maps and trick your eyes into seeing detail with only 4-16 colours is nothing short of genius. Also take a second to consider that taking a screen shot of the game is larger than the entire game itself and let that sink in...
I think the dramatic increase in storage, processing power and ram over the last decade is making us shit developers - all of us. Just take one look at chrome, skype or anything else mainline really and it's easy to see we no longer give a rats ass about memory anywhere except our monthly AWS/GCE bill.
We don't have to be creative or even mindful about anything but the most significant memory leaks in order to get our software to run now days. We also don't have constraints to distribute it, fast deliver-ability is rewarded over quality software. It's only expected to stay in production 3-4 years anyway.
Those guys were the true "rockstars" and "ninja" developers and if you can't acknowledge that you can take ya React app and shovit. -
It's 00:54. I'm supposed to wake up at 8.30AM. Not even tired. In front of my computer, with a frozen Visual Studio Code on the left screen and a frozen Madeon music on the right screen.
My CMS won't get compiled anymore, due to lack of memory. I have 16gb of RAM, gave it 4 of them, and it froze. If I give it less, it just won't compile. Why. I can't figure out wether if it's my code which has some memory leaks or if there's just too much JavaScript in it. What did fuck up? My code? React? Material-UI? The way I want to mix them all together? Maybe I just shouldn't have used React to cover up everything, and maybe I shouldn't have used Ruby on Rails the way I did.
Fuck.
What do I do now.10 -
I have not gotten a new phone in years. I am happy with my current one but unfortunately you need fucking at least 4gb of ram in your PHONE to run apps nowadays so it freezes frequently.
Watched the launch event for the OnePlus 7 very impressed. Price: high but not too high.
What they failed to mention, and I only found out a few hours later from a reviewer (Linus) is that they removed the audio jack. Come on guys that's just a dick move.
There are still enough redeeming qualities that I will purchase the device (90hz amoled 1440p 93% screen display? *Drooling*) but I am disappointed and feel slightly conned that in your detailed, 30 minute overview of the phone, you avoided mentioning this.21 -
We'd just finished a refactor of the gRPC strategy. Upgraded all the containers and services to .Net core 3, pushed a number of perf changes to the base layer and a custom adaptive thread scheduler with a heuristic analyzer to adjust between various strategies.
Went from 1.7M requests/s on 4 cores and 8gb ram to almost 8M requests/s on the same, ended up having to split everything out distributed 2 core instances because we were bottlenecking against 10gb/e bandwidth in AWS.2 -
First of all, a great channel to follow and where all this is from: https://youtube.com/watch/...
It listed a lot of open source news I missed myself and I'm sure others did too, for those that are too lazy to watch the video or open the description, I've stripped away the links and "X version got released" just to give an idea of what he covers.

*Furiously cracks fingers and starts typing*
When I first tried out mobile app development some weeks ago I found it pretty fun. Now when I have a internship with a company to create a Android app I was kind of excited. Now after just a week I don't think I will come back to Android development again. Android studio eats my RAM and made my computer hang itself, and the thing I despise the most is gradle! AS f**ks with my gradle also so now they are all gone and i'm trying to rewrite them by myself...
*Furiously tries to calm down*10 -
!rant
I started learning to use Hadoop recently, and am running a VM with all I need installed on it (the HDF Sandbox to be exact). The VM wants 8GB to run and my laptop only has just that, except it also needs to run Windows at the same time...
At first I thought I was screwed, that I'd need a more capable computer to learn. I gave it a shot anyway, and told VirtualBox to give the VM 4GB, hoping the VM itself would use RAM swap to function. And it did!
What I didn't expect was Windows not slowing down even a bit. Turns out Windows can triple the computer's RAM with virtual memory that it keeps on disk.
So the bottom line is: my VM is using 4GB as if it was 8GB, and at the moment my Windows is using 8GB as if they were 14GB. All of this without breaking a sweat. The more you know!3 -
So recently I had an argument with gamers on memory required in a graphics card. The guy suggested 8GB model of.. idk I forgot the model of GPU already, some Nvidia crap.
I argued on that, well why does memory size matter so much? I know that it takes bandwidth to generate and store a frame, and I know how much size and bandwidth that is. It's a fairly simple calculation - you take your horizontal and vertical resolution (e.g. 2560x1080 which I'll go with for the rest of the rant) times the amount of subpixels (so red, green and blue) times the amount of bit depth (i.e. the amount of values you can set the subpixel/color brightness to, usually 8 bits i.e. 0-255).
The calculation would thus look like this.
2560*1080*3*8 = the resulting size in bits. You can omit the last 8 to get the size in bytes, but only for an 8-bit display.
The resulting number you get is exactly 8100 KiB or roughly 8MB to store a frame. There is no more to storing a frame than that. Your GPU renders the frame (might need some memory for that but not 1000x the amount of the frame itself, that's ridiculous), stores it into a memory area known as a framebuffer, for the display to eventually actually take it to put it on the screen.
Assuming that the refresh rate for the display is 60Hz, and that you didn't overbuild your graphics card to display a bazillion lost frames for that, you need to display 60 frames a second at 8MB each. Now that is significant. You need 8x60MB/s for that, which is 480MB/s. For higher framerate (that's hopefully coupled with a display capable of driving that) you need higher bandwidth, and for higher resolution and/or higher bit depth, you'd need more memory to fit your frame. But it's not a lot, certainly not 8GB of video memory.
Question time for gamers: suppose you run your fancy game from an iGPU in a laptop or whatever, with 8GB of memory in that system you're resorting to running off the filthy iGPU from. Are you actually using all that shared general-purpose RAM for frames and "there's more to it" juicy game data? Where does the rest of the operating system's memory fit in such a case? Ahhh.. yeah it doesn't. The iGPU magically doesn't use all that 8GB memory you've just told me that the dGPU totally needs.
I compared it to displaying regular frames, yes. After all that's what a game mostly is, a lot of potentially rapidly changing frames. I took the entire bandwidth and size of any unique frame into account, whereas the display of regular system tasks *could* potentially get away with less, since most of the frame is unchanging most of the time. I did not make that assumption. And rapidly changing frames is also why the bitrate on e.g. screen recordings matters so much. Lower bitrate means that you will be compromising quality in rapidly changing scenes. I've been bit by that before. For those cases it's better to have a huge source file recorded at a bitrate that allows for all these rapidly changing frames, then reduce the final size in post-processing.
I've even proven that driving a 2560x1080 display doesn't take oodles of memory because I actually set the timings for such a display in order for a Raspberry Pi to be able to drive it at that resolution. Conveniently the memory split for the overall system and the GPU respectively is also tunable, and the total shared memory is a relatively meager 1GB. I used to set it at 256MB because just like the aforementioned gamers, I thought that a display would require that much memory. After running into issues that were driver-related (seems like the VideoCore driver in Raspbian buster is kinda fuckulated atm, while it works fine in stretch) I ended up tweaking that a bit, to see what ended up working. 64MB memory to drive a 2560x1080 display? You got it! Because a single frame is only 8MB in size, and 64MB of video memory can easily fit that and a few spares just in case.
I must've sucked all that data out of my ass though, I've only seen people build GPU's out of discrete components and went down to the realms of manually setting display timings.
Interesting build log / documentary style video on building a GPU on your own: https://youtube.com/watch/...
Have fun!20 -
So for a while I have wanted to build a raspberry pi cluster. In the spirit of shia labeouf I got started last saturday.
I had two pies lying around so I figured I'd run some experiments before I invested in a lot of hardware. After about a day I had turned the two pies into a shared cluster when disaster struck....
I had completely ignored the fact that you cannot run 32 or 64bit software on an arm processor (I know... I'm a java developer). So when I booted my service and the load balancer, I found that nothing worked. So pretty bumbed out, I quit the project.
Later that day I found a crazy guy who had bought a batch of 400 small form factor PSUs (300W) and internally I laughed at him a little. I mean, who's gonna sell 300W irregular power supplies. Then, just as I was about to go to bed I found this guy, he was selling from a batch of CPU-onboard motherboard for 10 bucks each and everything clicked!
I did some quick calculations and decided I could probably gather enough cash to get: 10 motherboards, 10 2GB ram dimms, 10 Sata disks and 14 PSU (in case some fail) and some misc hardware for networking and such.
So... Long story short, I am going to build a cluster computer, the first version is going to have 10 nodes and I am waiting for delivery right now!12 -
TLDR: There's some days where the Gods of IT are not with you. Just lost a whole day of work.
So this morning, we (me and my team) big performance issues with our web app. Lot's of requests time out, big latency, etc
Try to ssh to VPS, latency of 10 seconds between user input and output.
Usual checks: RAM ok, Proc ok, hard drive ok, reboot server (20 minutes), update/upgrade
We decide to call OVH. After 15 minutes call, we try to reboot in rescue mode. Reboot fails at 60% + everything freezes.
After an hour, OVH opens an incident ticket on +200 vps instances (including mine) everything is down during +1h
Finally everything is okay ! Even had time to migrate my new database schema.
Still, quick heavy on the mind but feels good to go home with everything working out correctly -
A Rant that took my attention on MacRhumors forum.
.
I pre-calculated projected actual overall cost of owning my i5/5/256 Haswell Air, which I got for $1500.
After calculations, this machine would cost me about $3000 for 3 years of use.
(Apple Care, MS Office Business, Parallels, Thunderbolt adapter to HDMI, Case... and so on).
Yea... A lot of people think it's all about the laptop with Apple. nah... not at all. There's a reason Apple is gradually dropping the price of their laptops.
They are slowly moving to a razor and blade business model... which basically is exactly what it sounds like - you buy the razor which isn't too expensive, but you've got no choice but to buy expensive additional blades.
I doubt Apple is making much money from laptop sales alone... well definitely not as much as they were making 5 years or so ago (remember the original air was about $1800 for base model, and if i remember correctly - $1000 additional dollars to upgrade to 64GB SSD from the base HDD.
Yes, ONE THOUSAND DOLLARS FOR 64GB SSD!
Well, anyways, the point is that Apple no longer makes them BIG bucks from the laptop alone, but they still make good profits from upgrades. $300 to go to 512GB SSD from 256, $100 for 4GB extra ram, and $150 for a small bump in processor. They make good profits from these as well.
But that's not where they make mo money. It's once you buy the Macbook, they've got you trapped in their walled garden for life. Every single apple accessory is ridiculously overpriced (compared to market standards of similar-same products).
And Apple makes their own cables and ports. So you have to buy exclusively for Apple products. Every now and then they will change even their own ports and cables, so you have to buy more.
Software is exclusive. You have no choice but to buy what apple offers... or run windows/linux on your Mac.
This is a douche level move comparable to say Mircrosoft kept changing the usb port every 2-3 years, and have exclusive rights to sell the devices that plug in.
No, instead, Intel-Microsoft and them guys make ports and cables as universal as possible.
Can you imagine if USB3.0 was thinner and not backwards compatible with usb2.0 devices?
Well, if it belonged to Apple that's how it would be.
This is why I held out so long before buying an apple laptop. Sure, I had the ipod classic, ipod touch, and more recently iPad Retina... but never a laptop.
I was always against apple.
But I factored in the pros and cons, and I realized I needed to go OS X. I've been fudged by one virus or another during my years of Windows usage. Trojans, spywares. meh.
I needed a top-notch device that I can carry with me around the world and use for any task which is work related. I figured $3000 was a fair price to pay for it.
No, not $1500... but $3000. Also I 'm dead happy I don't have to worry about heat issues anymore. This is a masterpiece. $3000 for 3 years equals $1000 a year, fair price to pay for security, comfort, and most importantly - reliability. (of course awesome battery is superawesome).
Okay I'm going to stop ranting. I just wish people factored in additional costs from owning an a mac. Expenses don't end when you bring the machine home.
I'm not even going to mention how they utilize technology-push to get you to buy a Thunderbolt display, or now with the new Air - to get a time capsule (AC compatible).
It's all about the blades, with Apple. And once you go Mac, you likely won't go back... hence all the student discounts and benefits. They're baiting you to be a Mac user for life!
Apple Marketing is the ultimate.

This always gets me:
Developers complaining that their 4 year old / cheap ass computer is slow.
Get. A. New. One.
It's not that hard.
Here, let me do one for you:
https://computeruniverse.net/en/...
I just went to a site that delivers across Europe, and selected a cheap laptop with a decent CPU and SSD. Short on RAM, sure, and without a Windows License. But you can buy RAM for an additional 50$, and that brings you to a total of 550€, delivery included. And it will WORK. And it will be fast.
It's too expensive?
No, not exactly. Wherever you are in the world, if you can code decently, good enough to have the right to complain about development tools, you are eligible to at least 10$ per hour income as a freelancer across the globe. I've had such opportunities offered to me by many organizations, especially non-profit ones that need cheap employees. I actually was offered more but let's stick to 10$ per hour.
So that's 1600$ per month. Enough to buy 3 such laptops. Oh, taxes, I forgot. So you get 2 laptops. Wait! You need food and everything else. Well if you're in a country where that offer actually makes sense, then it's likely that you can live off of 400$ per month quite well. Maybe 800$ if you need to pay rent.
So that's roughly 1 month of work for a laptop that will make you not waste time on waiting for stuff.
Sweet! 1 Month! What does it get me?
Well assuming that you have no laptop, it gets you A JOB that pays you 1600$ per month.
But if you DO have a laptop, you can sell it for cheap, and benefit from the following:
1. Boot-up time from 30-60 seconds to 10 seconds.
2. Installing software - from 1 minute to 10 seconds.
3. Opening a browser - from 10 seconds to 1 second.
4. Opening an advanced text editor (Atom, VS.Code) - from 10 seconds to 1 second.
5. Searching for a file on your entire hard drive - from 1 hour to 2 minutes.
....
You get the point. Waiting is reduced by several times.
So how much do you really wait when coding?
Well are you compiling? Are you opening a new project and the IDE needs to re-index the files? Are you opening programs like a terminal emulator, browser and such? Are you using virtual machines for dev environments?
Well all of these processes become several times faster. Depending on how often you do it, you'll be saving yourself from 1 hour per day to upto 4 hours per day (my case, where a HDD would be just out of the question).
How much is that time worth? At least 10$ per day. If you're working for 20 days per month, 240 days per year, that's a total of 2400$. And for the life time of that crappy laptop of 2 years, that's 4800$ saved. And that's with hugely conservative numbers. Nobody pays 10$ per hour any more, except if you've just started in the industry. I know because I've been there.
Please, for all that's sacred to you, justify right here, right now, HOW THE FUCK can you not afford to get that 8GB of RAM, that cheap ass SSD for 100$, or even a brand new laptop (hey! it's even portable and has FHD graphics on it!) for 550$.
That's why every time I hear someone who is a professional developer complain that they don't have money for a decent machine, I have to ask: why the fuck are you wasting yours and everyone else's time?!10 -
I already wrote a rant about this yesterday, but since I'm a sysadmin trying to convert to dev.. I dunno, maybe it's not a bad idea to muddy the waters a bit and talk about why not to be a sysadmin.
Personally I think it's that the perceived barrier to entry is just too high, while it isn't. You don't need a huge Ceph cluster and massive servers when you're just starting out. Why overbuild an appliance like that if it's gonna start out at maybe 5 requests a minute?
Let's take an example - DNS servers! So there's been this guy on the bind-users mailing list asking how to set up a DNS server on 2 public servers, along with a website. Nothing special I guess - you can read the thread here: https://0x0.st/ZY-d. Aside from the question being quite confusing, there was advice to read RFC's, get a book, read the BIND ARM, etc etc. And the person to deny this? No one less than Stephane Bortzmeyer, one of the people who works for nic.fr (so he maintains the .fr TLD) and wrote some of those RFC's as part of the DNSOP working group in the IETF. As for valid reasons to set up a DNS server? Could just be to learn how the DNS works, or hell even for fun. As far as professional DNS servers go.. this (https://0x0.st/ZYo9) is the nugget that powers the K root server, one of the 13 root servers that power the root zone of the internet, aka the zone apex. 2 RJ45 connections, and a console connection. The reason why this is possible is the massive recursor networks that ISP's, Google DNS, Cloudflare DNS, Quad9, etc etc provide. Point is, you don't need huge infrastructure to run a server!
Or maybe your business needs email. How many thousands of emails per second are you gonna need to build your mail server against? How many millions will you need to store? If your business has 10 employees and all of those manage about 10k emails total.. well that's easy, 100k emails total. Per second? Hundreds of emails per second per employee? Haha, of course not. Maybe you'll see an email a minute at most. That is not to say that all email services are like this - it is true that ISP's who offer email to their customers, and especially providers like Microsoft and Google do need massive mail servers that can handle thousands of emails per second. But you are not Microsoft or Google. So yeah, focus on the parts of email that are actually hard.. and there is plenty.
Among sysadmins you have this distinction between "professional" sysadmins and homelabbers. I don't mind the distinction itself but I think both augment each other. If you've started out by jumping into a heap of legacy at an established company, you will have plenty of resources, immediately high complexity, and probably a clusterfuck right away. But you will have massive amounts of resources. If you start out with a homelab, you will have not many resources, small workloads, and something completely new for you to build and learn with. And when running a server like that, you'll probably find that the resources required are quite small, to provide you with your new services. My DHCP servers take 12MB memory each. My DNS servers hover around the 40MB mark. The mail server.. to be fair that one consumes around 150. But if you'd hear the people saying that you need huge servers.. omg you need at least a TB of RAM on your server and 72 cores, massive disks and Ceph!1!
No you don't. All that does is scaring people away and creating a toxic environment for everyone. Stop it.1 -
I started out on a Sinclair ZX 80. It has just 512 bytes of ram and you had to use a function button together with a key for each command since it did not have enough memory to keep the source in memory ;)
I attended few basic courses and then went on to hold them.
After a year there was suggestions of starting pascal courses so during the summer I read up in turbo pascal 5.5 but since the summer home did not have electricity I had to do it all theoretically for the first month before getting to try it out.
I got to try visual basic when doing school practice with Microsoft but the name was not set by then as it was a few months before the release.
Thats also where the more professional programming got going even though I did one pascal program that was used professionally before that. -
Question: What was the worst mistake you made in Linux?
So... Because I've finally upgraded my PC (rip money on bank account) I can now run a VM with Linux all the time that isn't slow as a snail.
I installed Linux mint, with 4Gb of Ram and 6 cores, and it runs like a brize, while I play on windows and stuff. BTW I'll be using the VM for programming stuff, since I'm finally at home (homesick because of burn out), when I'm better I'll finally have the patience and memory to learn new stuff and get my projects up and going.
And because I've never really used Linux I'm watching YouTube videos about Linux, and found a Perl I've watched before, #Linux Sucks
And It's great... I get so many laughs, but also, learn stuff I didn't know, like, how Linux Pros make mistakes that Windows users can't even do, like breaking the OS.
So... I would love to know, what was the worst mistakes you ever done on Linux? How did you brake you're system?
BTW this would also be great for noobs like me to not make them... I hope. Since I'll be moving full Linux when I'm comfortable.
BTW @dfox this would be a great wk ...18 -
I'll post a rant (will be long) soon-ish on the root of the asinine problem...
TL;DR
Anyone got a better suggestion of killing a WLAN router signal than a Faraday Cage?
-----------------------
As to the point as I can manage atm...
My ISP forces a proprietary router/modem for them to script my static IPv4 block (/28, aka 13 usable). Modifying this equipment in any way or using the vast majority of tactics to modify its behaviour = Federal Felony... with my history, it couldn't be construed as mistake/ignorance of this fact, so I'd likely end up working for some branch of the gov to mitigate the costs of standard prison (on both ends... handicapped af = expensive af to comply with base human rights laws... plus I'd be a dangerous prisoner from what I've been told).
I NEED the ipv6 functionality TOTALLY off... I've written this into every kernel and every container config at kernel level.
The issue is, I don't trust their shit device (which "should" also be set to no ipv6 via gui... non-GUI = fed felony).
This horrid device, they apparently made them for home use initially (to be fair it has decent specs and tolerable RAM), so included WiFi... that comes on by itself.
Disable the WiFi!... except I cant (at least not without 'tampering').
Why? Well acc to the GUI it's not enabled in the first place. Acc to the 'tech support' it's apparently a paid feature (yes, nonsense) that I have not paid for (nor would I), meaning on their end's GUI and DBs I also don't have WiFi ability from that dev.
So... Not trusting the other settings and the dev, being something im not allowed to directly config outside of their GUI that doesn't realise it's putting out a usable signal despite registering DHCP on behalf of that non-existent signal. I NEED to kill those signals.
I realise it likely sounds extreme to make and use a Faraday Cage for a router/modem (secondary modem, it parses the initial modem's output, via script, to allow the static block to be accessed). I really dont know any other way that's legal to restrict it.
Oh, in case unclear, I have tried so many ways to get them to just allow me to use any device (pref. mine, but even their's) that i can simply script myself... it's a no-go.20 -

Pro tip: always make sure your methods return the correct variable.
I’m currently working with deep neural networks using tensorflow. I needed to generate some test data and wrote a program to create it. I had two text files which each consisted of approximately 5000 lines of text.
I wrote a method that should sort out some words, and make my final data shorter. When I executed the program first time on our server, it spent about 25 minutes, then crashed due to MemoryError (which in Python means that the server didn’t have enough ram). That seemed quite weird since I only had about 10k lines of text, and I even sorted out a bunch of it, and the server has 128gb ram, and nothing’s using it.
Apparently I returned the wrong variable. That meant that my program tried to save 750 quadrillion lines of text rather than just a few thousand.
Always make sure to return the correct variables!1 -
Somebody ranted about his teacher showing windows presentation and teaching nothing. I wanted to comment that post but i have enough material to make the whole rant out of it.
Well at least you have those presentations! In my school we have 2 IT classrooms one with win xp, 1ghz cpu, 0,5gb ram computers and one with win vista, 2 core 2ghz cpu and 2gb of ram PCs.
Guess what room our teacher is using... of course the worse one! The second one is fine, few years ago another theacher had been using it!
I tried to convince him to change rooms but he is coming up with silly exciuses! (like "server is not working here!", well i fixed it with my friend but why are you even talking about it when you are not using yours in old class!)
PS. That server is useless anyway, every pc is connected to router that is connected to internet so supervisor pc is not mandatory, only acces restriction is enforced by win accounts.
I heard from students from my class (that picked that optional IT course) (i'm in high school) that gimp is not working because pc's are so bad!
Sometimes even notepad frezzes.🤔
Not only class is shite but teacher clearly has no idea what is he doing. (in order to pass the final from IT you need to learn simple C++, up to simple foo objects) and of course he isn not even talking about that! On one lesson about sorting algorithms he gave everybody 10 small pieces of paper with numbers on them and told everybody to sort them manualy, because he didnt know how to do it himself! So there is no doubt they wont be able code it.
I need to mention that i volontered to "clean, fix" that classroom (in order to convince teacher to move). And in that class i saw programms written in c++ on every computer! That means somebody was teaching propely before! 😣
I feel sorry for those guys, they are just waisting time. I would fall for it as well but i decided i can learn coding in home ;).
Well, results are shocking, after 1 month of coding i learned C# and i can basicly make any algorithm i ever wish. I learned about computer operation so well that i can nearly teach computer science. (i helped my friend in usa that is a electronic student with that and i'm very proud of it 😁) and it class still can't even use all 3 loops correctly... 😥 Ok i must admit i have been coding for a looooong while so i had time to learn basic c,c++ and pc operations before, but point still stands.
Why the hell are you wasting life of those studends? Why are you giving them a choice to learn coding WHEN YOU CANT EVEN USE PC YOURSELF?! (that it course is optional so you can apply if you want so)
I dont regret not bothering about it.1 -
A few days ago I decided to install Windows 7 on a VM (bad idea as it turned out). All fine and dandy and I ran Windows Update a few times to get it at least as up-to-date as it'll get.
I noticed that out of the 4GB RAM I had allocated, an svchost process responsible for the updates was gobbling up all the available memory, just leaving 82MB for everything else. The process itself was as you might imagine consuming over 3GB RAM just for itself. That's how an OS should work right after installation, I'm sure you'll agree.
So I complained about it. Haven't used Windows anywhere for a while so I wasn't used anymore to this level of efficiency. Disk activity went through the roof, though to be fair the underlying disk wasn't an SSD (qcow2 on ZFS on a spinning drive). RAM consumption is something I already covered. CPU temperature shot up to 95C.
So as any idiot would do, I disabled the service related to that process (the svchost process for wuauserv) and the problem went away. But I complained of course, saying that such amazing system utilization metrics wasn't something I expected. I mean for 4GB allocated, having as much as 82MB usable to get stuff done with! 95C on the CPU, on a lot of chips that's the junction temperature! Absolutely beautiful.
When I complained I heard that I had to replace the thermal grease. I do that twice a year. I wrote a custom fan driver for my system that works absolutely great. It was obviously shit. I must be a horrible sysadmin for solving a problem by eliminating the cause, and companies hiring me must be ashamed of themselves. My hardware must be shit (that's a common one with Windows users) despite being a business laptop and the guest system being a VM. Oh and I'm an idiot of course for complaining about such amazing system metrics in Windows.
I love Windows and its community...8 -
Time for a rant about shitstaind, suspend/hibernate, and if there's room for it at the end probably swappiness, and Windows' way of dealing with this.
So yesterday I wanted to suspend my laptop like usual, to get those goddamn fans to shut up when I'm sleeping. Shitstaind.. pinnacle of init systems.. nope, couldn't do it. Hibernation on the other hand, no problem mate! So I hibernated the laptop and resumed it just now. I'm baffled by this.
I'll oversimplify a bit here (but feel free to comment how there's more to it regardless) but basically with suspend you keep your memory active as well as some blinkenlights, and everything else goes down. Simple enough.. except ACPI and I will not get into that here, curse those foul lands of ACPI.
With hibernation you do exactly the same, but on top of that, you also resume the system after suspending it, and freeze it. While frozen, you send all the memory contents to the designated swap file/partition. Regarding the size of the swap file, it only needs to be big enough to fit the memory that's currently in use. So in a 16GB RAM system with 8GB swap, as long as your used memory is under 8GB, no problem! It will fit. After you've moved all the memory into swap, you can shut down the entire system.
Now here's the problem with how shitstaind handled this... It's blatantly obvious that hibernation is an extension of suspend (sometimes called S3, see e.g. https://wiki.ubuntu.com/Kernel/...) and that therefore the hibernation shouldn't have been possible either. The pinnacle of init systems.. can't even suspend a system, yet it can hibernate it. Shitstaind sure works in mysterious ways!
On Windows people would say it's a hardware issue though, so let's talk a bit about that clusterfuck too. And I'll even give you a life hack that saves 30GB of storage on your Windows system!
Now I use Windows 7 only, next to my Linux systems. Reason for it is it's the least fucked up version of Windows in my opinion, and while it's falling apart in terms of web browsing (not that you should on an EOL system), it's good enough for le games. With that out of the way... So when you install Windows, you'll find that out of the box it uses around 40GB of storage. Fairly substantial, and only ~12GB of it is actually system data. The other 30-ish GB are used by a hibernation file (size of your RAM, in C:\hiberfil.sys) and the page file (C:\pagefile.sys, and a little less than your total RAM.. don't ask me why). Disable both of those and on a 16GB RAM system, you'll save around 30GB storage. You can thank me later.
What I find strange though is that aside from this obscene amount of consumed storage, is that the pagefile and hibernation file are handled differently. In Linux both of those are handled by the swap, and it's easy to see why. Both are enabled by the concept of virtual memory. When hibernating, the "real" memory locations are simply being changed to those within swap. And what is the pagefile? Yep.. virtual memory. It's one thing to take an obscene amount of storage, but only Windows would go the extra mile and do it twice. Must be a hardware issue as well.
Oh, and swappiness. This is a concept that many Linux users seem to misunderstand. Intuitively you'd think that the swappiness determines what percentage of memory it takes for the kernel to start swapping, but this is not true. Instead, it's a ratio of sorts that the kernel uses when determining how important the memory and swap are. Each bit of memory has a chance to be put into either depending on the likelihood of it being used soon after, and with the swappiness you're tuning this likelihood to be either in favor of memory or swap. This is why a swappiness of 60 is default most of the time, because both are roughly equally important, and swap being on disk is already taken into account. When your system is swapping only and exactly the memory that's unlikely to be used again, you know you've succeeded. And even on large memory systems, having some swap is usually not a bad idea. Although I'd definitely recommend putting it on SSD in a partition, so that there's no filesystem overhead and so that it's still sufficiently fast, even when several GB of memory are being dumped in.6 -
Concerning my last post on the two Commodores, (https://devrant.com/rants/963917/...) here's the great story behind the boxed one.
So at the place where I interned over the summer, I helped the tech dept. (IT herein) move to a new bldg. We had to dismantle most of the network infrastructure stuff, so we were in the server room a lot. First day on the job, Boss shows me server room, I'm amazed and all because this is my first real server room lol.
We walk around, and there's a Commodore 64 box on a table, just kinda there. I ask, "Uh, is that actually a C64?" B: "Yeah, that's E's." Me: "E?" (name obfuscated) B: "Yeah, E's a little crazy." Me: "Is it actually in there?" B: "Absolutely, check it out!" *opens box and sees my jaw drop* Me: "Well, alrighty then!" So that lingers in my mind for a while until I meet E. He is a fuckin hilarious guy, personifying the C64, making obscure and professionally inappropriate references. Everyone loves him, until he pranks them. He always did.
We’re in the server room, wiping some Cisco switches or something, and we have some downtime, so I ask him about the 64, and he's like "Yeah, I haven't had time to diagnose her issues much. If you want her, go ahead, see if you can make it work!" Me: "You're kidding, right?" E: "Nah, not at all!"
That day I walked out with a server motherboard, 2 Xeon CPUs and some RAM for the server (all from an e-waste bin, approved for me to take home from boss) and a boxed C64. Did a multimeter test on the PSU pins, one of the 9vAC pins is effectively dead (1.25v fluctuating? No thanks.) but everything else is fine except for a loose heatsink and a blown fuse in each C64. Buying the parts tonight. I wanna see this thing work!1 -
I finally managed to install Gentoo on my laptop.
My experience with it was very good. The hand book is enough but I got an error which the handbook didn't mention so I looked online and asked in their Discord. Everyone was fast, friendly and very helpful. If I compare NixOS to Gentoo, NixOS is rather the opposite. Heavily lacking documentation, community is rather slow and from what I've seen on reddit, there is a drama going on lol.
Time wise:
It should have taken me 2 days. But it took me 2+ weeks instead (I also got lazy at one point and procrastinated). And today when I reinstalled Gentoo (my previous Gentoo install didn't boot) and knew what I was doing, I did it in 3 hours.
Before that I tried out NixOS and I liked it but it had its flaws.
https://devrant.com/rants/10817333/...
Now I will experiment with Hyprland and i3.
I will also create an install script out of all of it at one point.
I'm really impressed by the very low RAM usage btw. Holy shit!
A tip for new comers: Begin with the dist-kernels. Later on you can still customize new kernels and build them from source. Otherwise you'll face issues.13 -
Got myself a new work computer. Aside from setting everything back up, it's been an absolute treat. I didn't even have to move to Windows 11.
Why Dell feels the need to put 7TB of garbage, including literal adware that spews notifications, escapes me. All it does is hurt their reputation.
I would have been allowed to build my own from scratch, but I didn't even ask since it's been so long since I built my last machine and I don't even know where to start hardware wise these days.
12th gen i7
GTX1080 that has all the video memory I could need
RAM just pouring out of the thing

I wrote a parody of Sound of Silence based on the struggles of cleaning up people's shit in the shop
============
Hello problems, my old friends
I've come to talk with you again
Because a driver softly creeping
Left its seeds while RAM was leaking
And the vision that was planted in my brain
Still remains
Within the sound of crashing
In restless dreams I walked alone
Narrow bands of networking
'Neath the halo of a burned-out fan
I turned my collar to the hot and spinning
When my eyes were stabbed by the flash of an LED light
That split the night
And touched the sound of crashing
And in the naked light I saw
Ten thousand tasks, maybe more
Programs malloc with no swap
Programs writing with no space
Programs writing bits that voices never play
And no one dared
Disturb the sound of crashing
"Fools, " said I, "You do not know
Malware, like a plague, it grows
Hear my words that I might teach you
Take my tools that I might help you"
But my words, like silent raindrops fell
And echoed in the wells, of crashing
And the programs bowed and prayed
To the malware god they made
And Windows flashed out its warning
In the words that it was forming
And Windows said, "The words of the prophets are written in the event log
And dumped over COM"
And whispered in the sounds of crashing2 -
Just started as an intern as a web developer in a small company. I have about 4 semester of coding experience and was hoping to learn a lot new things. Well it turns out that the main developer who's responsible for building our product has no fucking clue what he's doing. Our biggest document has about 6k lines and it kills my 8 GB ram notebook. Instead of writing one nice function, solving the problem which is occurring frequently, he wrote the same fucking thing multiple times... In the same fucking document. That's just one of many things.
Well now my job is mostly trying to stay cool, while my notebook gets hot af and somehow keeping my code OCD bearable7 -
My uncle has definitely been my biggest influence. My parents never understood computers and refused to buy one. Eventually my uncle gave me an old Win95 box with an 8GB HDD, and 512 MB of RAM(most other people in the world were running XP at this point). The thing was completely useless as a computer to do work on when I received it.
The internet wasn't really a thing yet back then, but I managed to figure out how to clean up the OS, as well as taking it a part and figuring out the parts.
He was the one who taught me that with computers, all things are possible.
From there he was always buying me books about programming, and pointing me in the right direction. He was never one to give me the answer, but always told me where to look or what to ask.
Now I'm the main web developer at my company and I love what I do. -
I need to estimate how much ram and CPUs my team will need next year for our apps... That have yet to be built.
We load a lot of data feeds with batch processes running on a few large machines, some can use like 30 GB RAM at times...) which should be a lot less if we get the data real time I hope...
But wondering how to estimate well... I sorta did a worse case analysis where I just multiply and sum # CPUs/memory* nodes*approx apps...
Comes out to be like 600 CPUs and 800 RAM... So wondering if that's ok...
RAM is ok but # of CPUs is way higher bc now all the apps basically run on their own machines...13 -
I'm fully convinced that VS Code is a fork of MS Word. How else could they manage to make their autocompletion features so disgustingly intrusive?
I'm actually surprised that it hasn't tried to capitalize the first letter of each sentence... yet.
I WISH TO END MY HTML TAGS WHEN I FUCKING WANT TO! I WANT TO WRITE A SINGLE QUOTE SIGN IF I WANT TO!
And fuck their fucking "Preferences" menu. Those dropdown boxes are absolute fucking garbage.
Fuck their fucking JSON fuckery. If they cant fit their custom settings into a GUI, it's gonna suck anyway.
Fuck their fucking CPU and RAM requirements. If it manages to lag on a Thinkpad T420, fuck it.
For everything that Microsoft has created, there's an objectively better alternative out there. I'll stick to fucking Atom.4 -
I'm considering to build a powerful, small/semi-portable mini-ITX PC. Just small box you can easily travel with, kinda like a laptop but a lot cheaper and without a screen, keyboard and battery - I can't really work on laptops anyway (ergonomics!). Stuffed with something like a 4400G when Renoir (mainstream Zen2) comes out, so lots of processing power. Add 32GB+ RAM and one or two SSDs.
I'd say the reason is that I might work from abroad (remotely) next year, but honestly, it just gives me an excuse to break my piggy bank!
What do you think?11 -
Its 5:32 am been working on a new social media website opened up devrant to check whatsup and found out people really have amazing pc setups ♥️ I couldn’t post mine because my laptop has a broken keyboard and i use a usb keyboard also my laptop overheats so i stuck skateboard wheels to two of the back supports its an i5 processor with 3gb of ram but I love it,its what you do with your resources that really matters right ? with that broken keyboard i created a website for my college department which now 720 students and teachers use and we have around 8k entries in 3 days. Running the website on a local server at my college so no money spent on hosting. Taking small steps towards my goals and hopefully one day i’ll publish my setup1

About a month ago I sorted out some old electronic stuff and found my old laptop from 2011. A 2:nd Gen i7 8gb ram. I replaced it due to several bluescreens a day that later turned out to be caused by a faulty RAM module (was 16Gb back then).
Well, back then it became a backup laptop and went on the shelf and almost forgotten.
I went through all the old files on it and copied them to the NAS, replaced the mechanic drive with cheep SSD.
Used the old Win7 license key to upgrade to win 10 , dust off the fan, and it turned out to be usable.
I have much better computers so I would not use it for anything but today I gave it to my 6 year old nephew so he can start using a computer and build his knowledge. Worse case; If he spills soda on it he'll learn not to do that with the more expensive computers he will use in future.
So win win. I got to get rid of some junk that had been gathering dust for many years by giving my nephew an opportunity to get started with computers.
Finally, the timing: Microsoft announced a few days back that any new upgrade from windows 7&8 to 10 is no longer supported, but that computer still has a valid win 10 license as it was updated a month ago. -
Discovered this dumb backdoor into http://tutorialspoint.com/codinggro... months ago (June 2019). It's in Project>Compilation Options
It lets you execute any command on their server. I found a lot out:
The system is Red Hat based (Fedora/CentOS/RHEL)
It uses Linux kernel 3.20
It has 251GB of RAM
It has an 800GB HDD
Its IP is 172.17.0.2
Its main username is cg
It uses systemd init8 -
Say what you will, but nothing compares to the excessive pleasure one derives from transitioning from a top-tier development machine, the mere sight of which inspires awe from computer enthusiasts everywhere - the type of machine that seems to glisten in the light of the sunset as choirs ring out from nowhere in particular yet everywhere at once to sing it's praises as it's many full HD screens aluminate the room to offset the dying of the light.
To a mandatory, work provided claptrap with a Core 2 Duo, 2gb of RAM, 90GB of storage and an integrated GPU that can barely stomach 720p before it starts choking on its own mucous.
Truly fucking marvellous. -
When I was creating pixel art creator program and each pixel was an separated object, performance was horrible, and after 2 days of intensive thinking I figured it out. I made working canvas. Ram usage dropped by 1800% and speed increased by 40000%. My satisfaction was unimaginable.3

Needed my Windows 10 vm for parallax propeller development again. Should be pretty straightforward:
Start VM. Very unresponsive and Interface glitches with 2GB RAM so I give it 4GB to get on the desktop. Bruh, off to a good start.
Turns out that there are a few updates. So I try to install them. After two fucking hours Virtualbox screams at me for being out of storage. FFS Window$ updates managed to take up like 20GB extra.
Had to install it from scratch since my drive is full. Now my key won't activate because it is already activated. 15min support hotline, because 6*8 characters are necessary for a f*cking Phone activation.
Damage assessment:
1h of my life I will never get back, a barely viable operating system and I'm not even sure if USB passthrough works.
PSA:Gnome-Boxen has a superb unattended installer.8 -
TLDR; After my dad was lazy, I assembled the parts myself.
As far back as I can remember, if I think of my father he is sitting behind his pc playing games. It was like me, his escape.
When I was between 3-5 years old he upgraded his pc to one that supported windows 95. The most exciting thing I remember about his new pc is that it had a sound card or what passed as one anyway - think polyphonic ring tones in place of onboard beeps. It was fucking awesome.
He gifted his old 386 to my brother and I which we spent a blissful year or so playing DOS games on until it finally died. I wouldn't have access to a home computer again until I was 11 - touching my fathers computer was out of the question, never mind actually using it.
The reason I didn't have access to a pc was simply because he didn't replace his pc - he made minor upgrades to it until he died with a whopping 512mb of RAM. Seriously his pc specs were a bragging factor like geek porn - better than any else's I ever saw including his I.T friends (he was an electrical engineer), everyone knew this apparently aside from his boss...
Auto-cad started becoming a thing and my father for the first time ever had a reason to actually do work on a computer, he immediately used the opportunity to leverage his company into paying for a pc. To get better "value" for the company he ordered the parts in place of a pre-built machine - in reality he blew 90% of the budget on a new motherboard and graphics card to upgrade his own pc and the cheapest entry level components for everything else. The day they arrived he upgraded his own pc, threw the excess parts into a box and told us it was our new computer which he would put together over the weekend. He didn't.
After 3 months of nagging I was fed up and taking liberties with him that landed me more than one hiding, at some point he was over it and told me if I wanted something that badly I should do it myself. He walked into my room after becoming concerned if I had run away/hurt myself since he hadn't heard a whistle from me in 6 hours and I was battling my ass off trying to install windows 98.
He inspected my assembly gave me an approving nod and showed me that the hard drives physical jumper was set to slave and the rest is history. I hadn't used windows before, or built a computer let alone used one in years but somehow I always knew, it just clicked and made sense to me.
I didn't truly recognise just how much I had learn't watching him play DOS games over his shoulder and clean/upgrade his pc. It changed everything and thanks to only being allowed to watch him use a pc, once I finally had access to my own computer again I revered it and all it's possibilities. I knew I should use it to do something special. -
We specified a very optimistic setup for a data science platform for a client....
Minimum one machine with a 16 core CPU with 64GB RAM to process data.....
Client's IT department: Best we can do is an 8 core 16GB server.
Literally what I have on my laptop.
Data scientist doesn't use any out-of-memory data processing framework, e.g. Dask, despite telling him it's the best way to be economical on memory; ipykernel kills the computation anyway because it runs out of memory.
Data scientist has a 64GB machine himself so he says it's fine.
Purpose of the server: rendered pointless.5 -
So guys you all remember or know or will know how it is to be a student. Not that much money around, have to be responsible for the first time of your life and I don't know since we're all programmers here our Desktop/laptop that we invested our money on for the university is our life.
Recently I have found out that something is up with my laptop. My Ram should have been 8GB but it shows only 4. I almost fainted, I thought the seller caught an idiot (me) and sold it like that. So I decide, for some reason, to buy 2x8gb ram so I can have 16 since its the max support of the system.
I open the laptop and what to see but my laptop had 2x4gb in there.
Regardless I installed the new ones to find out what else but my PC is now showing just 8gb.
"Calm down Nick" I said maybe GPU uses it but no it only shows 4gb ram, the same amount the laptop came with so I guess it's integrated.
So now I can only think that the problem is occurred because my Father, dropped the laptop when I specifically told him to not have it in dangerous high places. I Googled around but everyone is talking just swaping the ram chips well yeah I did that 100 times, still the same.
Tl;Dr I'm freaking out because theres something up with my laptop9 -

Every time I write a rant or a comment from my phone, and I want to temporarily switch to another app to search or copy something, it's a fucking Russian roulette.
Will there be enough RAM, or will Android stop devRant thus losing all my content forever? Let's find out! The gun is loaded.
(What about handling the full activity lifecycle like Android requires?)
Now, I would like to attach a picture of the feared "task switch button", but I'm too afraid to lose everything, so fuck it3 -
I’m so frustrated and I don’t know whether to blame my 2015 Mac, Audacity, both, or my present inability to be able to afford a new Mac because EVERYTHING/EVERYONE IN MY HOUSE IS BREAKING, NEEDS THERAPY OR BRACES, AND LIFE IS NOTHING BUT EXPENSES!
I had just finished tediously transferring, restoring, and trying to export tracks from some old cassette I had of a jazz concert I played in years ago. Audacity froze because my Mac is now apparently underpowered at 8GB of RAM. But Audacity autosaves and on restart usually can restore you back to where you left off. So I tried to force quit it.
I couldn’t even force quit the stupid app and had to totally restart. I think that ruined whatever autosave I had because it could only restore half of the work I’d done. Another freeze finished off the Audacity project, making it TOTALLY BLANK AND WORTHLESS. I just deleted the whole damned thing and will have to start over. I WAS MINUTES AWAY FROM BEING DONE AFTER HOURS OF WORK!!!!!
Now the Mac wants to update to a supplemental release. With each release this expensive boat anchor gets slower and slower.
I just wanna throw all tech out the window. Every damned thing is planned obsolescence in 2 years and made in China anymore and I HATE giving that totalitarian regime any more of my money. Apple is complicit. ALL computer companies are. They could just bring the jobs back here and walk the walk, but they’re all talk.3 -
Accepting a 3 year old scratched and beaten PowerBook as my "new" dev machine. Especially when my personal, 4 year old one is as powerful but with double the disk space (SSD) and RAM... Then of course the new guys just joining actually do get new out of the box devices just as we're accepting that it's just not how the company works... I guess that's the bane of doing dev in a company that does resourcing as it's main focus thereby never understanding what's needed by us developers and why it is, or rather should be, different from the rest of the company.2

After waiting for almost a month, yesterday I went to check on how my computer was doing, since I hadn't got any messages or calls ever since.
I go to the store and ask one of the workers about how my laptop is doing, and that I'd left it there almost a month ago and that they'd tell me when it was time to get the papers and then the laptop itself. The girl asks me for my phone number and then my name, and found nothing on the computer. She goes somewhere inside the store and comes back with a colleague, who tells me that I need a process paper. I pull out the receipt the technician photocopied and signed because that was the only thing I had. I hadn't touched that part of my paste for the whole time after I left the computer there and I was 100% sure I didn't have the process paper with me until he started pressing me for it. I kept repeating that the technician told me that they'd call or message me when said process paper was ready, which I hadn't got any of those to go pick it up. The guy asks me if that were the number and name I'd given the tech guy and I said yes. Both of them disappear into the store again. They come back with a cardboard box and say that the surname written there was wrong by a char (as I've said before my name is unusual, and my surname is also unusual where I'm studying, but where I'm from there's like 5 or 6 families with that surname), so that's why they couldn't find it in the computer. After that they went through all the details I gave on the time of handing the PC and the number they told me was there was off by miles. I think I may have said a wrong digit but that number was way off. There should be some person who got calls or messages about a computer they don't even own LoL
They told me to try it and see if it was running OK and that I had 15d to go back if something was wrong
When I got home I turned it on, afraid it would start dying on me again LoL
I pass the login screen and the fan just starts working really hard and I'm worried. The ASUS guys reinstalled Win8 and the CPU is running wild already, going at about 3,5 GHz (2,5 max) and over 30% usage on nothing
After some minor inconveniences (making the USB with Win10 took longer than expected) I finally installed Win10 and the CPU usage drops to < 10% and runs at way below the 2,5 GHz max. It constantly uses <= 10-15% CPU and the fan makes no noise unless I put in a heavier game (like Oxygen Not Included - it asks for 4GB RAM minimum 8I), in which case it goes up a bit and runs at around 3 GHz, but it doesn't make as much noise as before, thank jesus. I'm gonna keep trying to see how it does and hope I don't have to go back to the store after the next 15d 8I
I can finally work and not be a leech on my friends because my old toshiba - which I forgot I'd brought with me to uni - is really old and it makes a lot of noise (the fan is constantly working too much but it's so old I don't bother anymore) and it heats my room a lot, so it's gonna be a nice change of pace HaHa4 -
My personal laptop suddenly broke.
Clearly, something in the motherboard got broken, because no LED is working, long press for hard reset is not working: only fans are on when I power on the button. To disconnect I should remove the battery.
It's an old (and very loved by me) laptop, but I explained it in the repair shop, and they told me they "will do all possible to repair it" by a reasonable price, so worth it.
After some days the call me to tell me that, after some tests like a display test or ram test, the problem is probably in the motherboard and they don't have the tools to fix that.
They can bring the laptop to another specialized shop for, of course, a much more expensive price.
How should I react? I'm very angry. When you told me you could "do all possible to repair it" after I told you where the problem probably is, it implies you have the tools, at least, to find out if the problem were there.
When we talk I said "yes, I accept I'll pay that price if you aren't able to fix it".
Being coherent, are you expecting to me to have the tools to pay you in that case?
I'm so tired of the impunity of companies for treating customers as if they had no idea about technology always even if in the most of cases is it. (My laptop was not apple)
What a waste of time and money.7 -
TL:DR linux newbie, looking for advice/links (skip to bottom for questions)
!rant
After i had been looking for a job for quite some time, a couple of months ago i got hired by "smaller" company doing web stuff. So far it have been a great place, good colleagues, and overall just having a great time!.
They seem to value me alot, so that's great!.
Anyway, yesterday i got called into a meeting - and got told they wanted me to start learning "Server stuff (linux)". That got me quite excited, because it always was something i wanted to learn - but never really got around to doing.
But i never touched a linux installation before, so i'm really on ground zero - but im not afraid, i'm a quick learner and quite efficient at googling :)
I figured i would ask here, since other people here always seems to be happy to help other people out.
So far i have manage to setup a server, install various stuff (php, mysql and so on) and done setup a couple of domains/subdomains on my server. Also got a vestacpinstallation working - so overall im quite happy so far.
I figured maybe somebody had some good links/advice for a linux newbie :).
* Performance/Security, will obviously be a big focus - anything i should look at? - any must look at?
* Monitoring tools, how do i monitor various websites running on my server? Here i'm thinking bandwitch, cpu/ram usage and so on pr site basis.
* Any other stuff i should be looking at?
Little about what the server will/should be running :)
* Centos
* vestacp
* WordPress installations only (e-commerce mainly)
* PHP 7 / MySQL / phpmyadmin5 -
The past couple of weeks I've been struggling with my laptop. It regularly ran out of memory and when that happens everything runs in a snail pace. I always thought 8GB would be enough for developing software, but I was terribly wrong.
So I ordered another 8GB and installed it yesterday. Later at work I looked at the ram usage and noticed that it was up to nearly 13GB!
I have no idea how I managed to get by with only 8 for so long. 🤔
FYI: I usually have 2 to 3 IDEs and a gazillion chrome tabs open 😅6 -

wk195 sounds like people are describing the weirdest places they had sex. Lmao, I'm sure this has gone through somebody's mind at one point.
Let's see, what else to vent about. Ah yes, today I took the public transport because I had to be somewhere in the evening and I wanted to avoid traffic congestion. Guess what? I ended up sandwiched between hordes of people in public transport. I hate that much more than sitting in my car dragging the clutch. At least I was somewhat relaxed and I had my own space (so to speak). Being smooshed between a horde of stressed people? And pushy people trying to ram their way through others "I have to get out, I have to get off here" while the others are clearly heading out too? No, that's not for me.
And I know what's gone through one's mind at one point: "Look at this sad state of the world, look at the highway inefficiently and disrespectfully stuffed, look at these people, most of them wearing sad looks on their faces from the routine of life and their subconscious dissatisfactions. The current system has many shortcomings. In fact, the entire system is wrong."
Well, I'm glad I'm home now. Space, temporal as well as physical and psychological, is indeed a core component of one's space (no pun intended). It's at times like these we need to look at our lives and make the necessary changes to change at least our own lives, there that the system is hard to change.4 -

Ranters, I would like your suggestion:
I have an early 2011 13" macbook pro with 4gb ram, 320gb hdd and <400 battery cicles, which I use mostly for web dev. I started to get some annoying slow downs since last osx update, and now I am trying to figure out what to do.
I could buy an SSD hd and a new set of 16gb ram (8gb x2) and replace the internals. This would increase the performance greatly.
Or I could sell it and buy a new Retina version (with 8gb ram and 128gb ssd), at the expense of not being able to update the ram or the hard drive in the future.
It is a ~$200 option against a $1200 one. What would you do if you were in my situation?11 -
The company I worked for had to do deletion runs of customer data (files and database records) every year, mainly for legal reasons. Two months before the next run they found out that the next year would bring multiple times the amount of objects, because a decade ago they had introduced a new solution whose data would be eligible for deletion for the first time.
The existing process was not be able to cope with those amounts of objects and froze to death gobbling up every bit of ram on the testing system. So my task was to rewrite the exising code, optimize api calls and somehow I ended up in multithreading the whole process. It worked and is most probably still in production today. 💨 -
So I recently finished a rewrite of a website that processes donations for nonprofits. Once it was complete, I would migrate all the data from the old system to the new system. This involved iterating through every transaction in the database and making a cURL request to the new system's API. A rough calculation yielded 16 hours of migration time.
The first hour or two of the migration (where it was creating users) was fine, no issues. But once it got to the transaction part, the API server would start using more and more RAM. Eventually (30 minutes), it would start doing OOMs and the such. For a while, I just assumed the issue was a lack of RAM so I upgraded the server to 16 GB of RAM.
Running the script again, it would approach the 7 GiB mark and be maxing out all 8 CPUs. At this point, I assumed there was a memory leak somewhere and the garbage collector was doing it's best to free up anything it could find. I scanned my code time and time again, but there was no place I was storing any strong references to anything!
At this point, I just sort of gave up. Every 30 minutes, I would restart the server to fix the RAM and CPU issue. And all was fine. But then there was this one time where I tried to kill it, but I go the error: "fork failed: resource temporarily unavailable". Up until this point, I believed this was simply a lack of memory...but none of my SWAP was in use! And I had 4 GiB of cached stuff!
Now this made me really confused. So I did one search on the Internet and apparently this can be caused by many things: a lack of file descriptors or even too many threads. So I did some digging, and apparently my app was using over 31 thousands threads!!!!! WTF!
I did some more digging, and as it turns out, I never called close() on my network objects. Thus leaving ~30 new "worker" threads per iteration of the migration script. Thanks Java, if only finalize() was utilized properly.1 -
The Jio phone out of India actually looks like a cheap ($10ish dollars) but worthy little option if you just want something to mess around on but don't want to drop $30-40 (plus shipping) on a pi.
Only 4gb storage, 512mb ram, 240x320 screen, dual core 1ghz, just enough to experiment if you're broke.
What do you think? Any indian programmers familiar with the Jio?
I'm not running out to buy it or anything. I stumbled across it and wonder what people's opinions of it are.14 -
Spent 2 days installing different versions of nvidia-driver, nvidia-cuda-toolkit, cudnn.
Disassembled pc due to some ram memory problems and pc not starting after freeze.
Looks like sometimes plug out and plug in various components on your motherboard fix pc lol. Destroyed PC casing that collapsed due to me sitting on it.
All of this to just find out tensorflow error and all crashes are from graphics card overheating after keeping it for some time at 82 celsius.
Added time.sleep to python code and looks like it's working, keeping temperature below 65 celsius.
Still ~100 times faster than cpu training so I can live with that.3 -
Having ram problems with my x299 system. When ever i put 2 8gb sticks in my pc just bluescreens on startup. But if i just put one in, in the b1 slot then it works just fine. But if i put the 2 8gb sticks in one in b1 and one in a2 then take out b1, then the a2 works. This works with both of the sticks so i dont think either one is dead. They are compatible, but blue screens whenever installed together. My bios is updated. Any ideas how to fix?8

Hardware dying again as of last night. Tried each RAM stick individually and my two original ones seem to be the cause so far. If it dies again with the extra sticks I had in, them I'm going to assume motherboard is packing up. Already tried a spare PSU and ruled that out.
Memtest died midway at random points several times and once it tried to boot around 10 times and died at various points along the way.
I just wish there was a more reliable way to test motherboards and power supplies on the PC itself. Also, I'll be stuck with only 4GB RAM from me new sticks 😭 -
Programming is like religion.
- you are making sombody to obey your will
- you have limited amount of resources (churches, processors, RAM, holy items)
- when you torture it, usually it will comply but not in way you are expecting
- smashing nail with hammer is not good idea (you can run out of resources again. Getting new CPU is costly as same as getting new believer)
So, who's in for new Church of Unhandled Exception?1 -
Let's increase my ram in my acer laptop. 1. It took me a week online to find out how many slots there are. 2. Then finding a manual with pictures for how to do it. No such thing. Technical manual from Acer? No such thing. I had to find a forum with one comment about my model.
There is no access to the location of ramslots. I had to completely unscrew everything because it's located at the bottom of the motherboard.4 -

Recep Tayyip Erdogan had a problem — after his army service, he got so used to cold that he could only sleep on a raw, cold metal grill. Usually, normal people put mattress on top, but Erdogan didn’t feel right this way. So, in one of his personal prisons, he established a social project for making a full metal bed for himself.
For starters, to calculate the shape, he took the smallest man ever (3 inches high) with his fingers and sunk him into molten plastic. “What are you doing?! It hurts!” — man screamed. “Shut up. You’re on an important mission. Your motherland won’t forget you.”
After three months, the bed was ready. It was more of the same — metal bars, but this time with some kind of structure built of metal hinges, rebar and strong springs. This was the day — this was the big reveal event. It took place in the same prison — three prisoners were ready to lay on their new full metal beds, while news crews congratulated Erdogan and celebrated his greatness. “Well, it is time!” — he said.
Prisoners laid flat. An awful screeching sound. Prisoner number two is bleeding out. The spring mechanism broke out and impaled his chest onto a large metal bar. He’s not breathing.
“Shut it down. Shut it all down. No more cameras, no more news”, — said Erdogan.
“Yes, our master”, — said news crews.
They wanted to draft me to Afghanistan.
“No!”, — a young officer shouted, misgendering me — “He doesn’t know the stages of pain. Useless.”

“You are a rave. Nothing but a rave.”
Raves spawned near your doors at night. Sometimes, they even spawned on the inside. I can’t say you were in danger, but it certainly wasn’t a pleasant thing to happen to anyone. They looked ugly. They dressed weird. They spoke in riddles.
“How do I move to Europe?”, — a rave asked.
“I…”
“Shut up!”
Rave took a door, suspiciously painted over and over multiple times, and started to slam my door with it, using it as a ram.
My door started giving in.
Alarm system.
On a separate note, to disable the alarm system, you have to speedrun Stanley Parable. It’s the hardest speedrun ever, specifically its hidden ending. It disables all alarm systems in three-mile radius IRL. No one knows how it works, but it does. Back to the danger zone!

It is a little known fact, but the liquid that Northern cities use to clean up snow isn’t quite what it seems like. It’s not salt — in reality, there are bases on Mars, and they store pink goo that… “iMpRoVeS” dead bodies. The liquid is biological in nature, and it expires. Expired liquid is recycled as snow melter. You learn that in high school, but now, living on a train, you should know that there are special learning rooms here, in every. single. carriage. The small gym ball with two handles on its sides is called Gandhi ball. Fun fact: if you wear headless Segways on top of your shoes, and then lay flat holding a Gandhi ball, you can reach the speed of 270 kph!

I have enough CPU/RAM to spare that any benefit I could get over using Rust instead of a higher level language is far outweighed by how ugly the syntax is.6 -
Amazon prime days sale...
I find a Fire 7 for $30 instead of $50. I think that would be great to put books on. I am thinking Kindle is an Android type device. Even some searches for Android tablets bring up Kindles on Amazon and web.
I get my kindle and like it. I signed up for trial of Kindle Unlimited. There is almost no selection for Kindle Unlimited for technical books. So I think I can just put the Paktpub app on the Kindle. No app for Kindle. That is okay, I can just put the Play store on there. Technically you can, if you side load it, but it will stop functioning after a day. Not an officially licensed Android device so cannot use Google services.
At this point I am not happy with the Kindle. I got it to read technical books and the selection of technical books is poor. At least on Kindle Unlimited. So I start looking at tablets on Amazon.
I find that there is a serious price breakpoint on Android tablets (cannot get Paktpub app for Windows tablets). For $100 (US) they are not very good. At > $150 they start getting really good feature wise. I end up buying a Samsung tablet for $200. It has 2GB ram and 8 cores at 1.6GHz.
I have been using the tablet for a few days now and am happy with what I can do with it. Now I have to wonder if Kindle is actually an upsell product rather than a serious product. I might not have went for a $200 tablet unless I had not had issues with the Kindle. Not sure there. Amazon made out for both product sales as I just gave the Kindle to the kids.
In the end I am very happy. Paktpub has all the tech books I can handle at the moment. Will probably not consider Kindle Unlimited again. This tells me that competition is good in the book sector. Good for the end user.5 -
My computer has gone to repair so for the meantime I'm computer-less. Which sucks big time because I have projects and tests coming up (not to mention personal projects and other stuff I've been asked to do) and I kinda have to leech off my friends and I don't like doing that, but, for now, it's what I'm doing. My old toshiba couldn't handle whatever I have to do, damn thing should be going through menopause or something. I wasn't a good owner LoL
I never really know if it'll boot during the first minute after I turn it on or if'll take it hours to do so, so I don't wanna risk it taking it with me to uni 😬 Not to mention it's still running Vista 😅
So my brother left to go to a friend's house until sunday so for the today and tomorrow I have access to the beast that is his computer ☺
I don't mean beast as a bad thing, it's a good computer, but it has an almost full SSD and I need to install a couple things so I can work on it :') (I'll uninstall them later and try to leave it as I found it LoL)
I can finally take a bit to play as well 😥 as I haven't been able to do so, as not only my PC is on repair, but I've been leaving uni late (after midnight - I valour my sleep OK). Luckily one of my house mates lets me use her PC after she goes to bed or her bf arrives to our house. The other day I managed to install steam and play a bit (she gave me permission to do so and I uninstalled them later) 😂 her computer almost died on me, it only has 4GB of RAM :') poor thing was over working to keep up LoL
Now, my brother's computer has a mechanical keyboard and besides the macro keys (they're on the far end of the keyboard, where you'd expect the shift/ctrl/caps lock/etc keys to be), I'm loving it tbh. It's a cheap keyboard, my mom didn't want to buy anything too fancy for him, but I like the sounds it makes 😅 may get one for myself (a mechanical keyboard I mean LoL. I really liked one I saw here on devRant that looked like a typewriter but it's WAY out of my league for now HaHa) -
During my small tenure as the lead mobile developer for a logistics company I had to manage my stacks between native Android applications in Java and native apps in IOS.
Back then, swift was barely coming into version 3 and as such the transition was not trustworthy enough for me to discard Obj C. So I went with Obj C and kept my knowledge of Swift in the back. It was not difficult since I had always liked Obj C for some reason. The language was what made me click with pointers and understand them well enough to feel more comfortable with C as it was a strict superset from said language. It was enjoyable really and making apps for IOS made me appreciate the ecosystem that much better and realize the level of dedication that the engineering team at Apple used for their compilation protocols. It was my first exposure to ARC(Automatic Reference Counting) as a "form" of garbage collection per se. The tooling in particular was nice, normally with xcode you have a 50/50 chance of it being great or shit. For me it was a mixture of both really, but the number of crashes or unexpected behavior was FAR lesser than what I had in Android back when we still used eclipse and even when we started to use Android Studio.
Developing IOS apps was also what made me see why IOS apps have that distinctive shine and why their phones required less memory(RAM). It was a pleasant experience.
The whole ordeal also left me with a bad taste for Android development. Don't get me wrong, I love my Android phones. But I firmly believe that unless you pay top dollar for an android manufacturer such as Samsung, motorla or lg then you will have lag galore. And man.....everyone that would try to prove me wrong always had to make excuses later on(no, your $200_$300 dllr android device just didn't cut it my dude)
It really sucks sometimes for Android development. I want to know what Google got so wrong that they made the decisions they made in order to make people design other tools such as React Native, Cordova, Ionic, phonegapp, titanium, xamarin(which is shit imo) codename one and many others. With IOS i never considered going for something different than Native since the API just seemed so well designed and far superior to me from an architectural point of view.
Fast forward to 2018(almost 2019) adn Google had talks about flutter for a while and how they make it seem that they are fixing how they want people to design apps.
You see. I firmly believe that tech stacks work in 2 ways:
1 people love a stack so much they start to develop cool ADDITIONS to it(see the awesomeios repo) to expand on the standard libraries
2 people start to FIX a stack because the implementation is broken, lacking in functionality, hard to use by itself: see okhttp, legit all the Square libs, butterknife etc etc etc and etc
From this I can conclude 2 things: people love developing for IOS because the ecosystem is nice and dev friendly, and people like to develop for Android in spite of how Google manages their API. Seriously Android is a great OS and having apps that work awesomely in spite of how hard it is to create applications for said platform just shows a level of love and dedication that is unmatched.
This is why I find it hard, and even mean to call out on one product over the other. Despite the morals behind the 2 leading companies inferred from my post, the develpers are what makes the situation better or worse.
So just fuck it and develop and use for what you want.
Honorific mention to PHP and the php developer community which is a mixture of fixing and adding in spite of the ammount of hatred that such coolness gets from a lot of peeps :P
Oh and I got a couple of mobile contracts in the way, this is why I made this post.
And I still hate developing for Android even though I love Java.3 -

Hardware Nerd Rant...
Spend nearly a year waiting for a super high end developer laptop. Tricked out MacBook Pro 2016: $4200+, Tricked out Surface Book 2/i7, $3700+
No 32GB ram because of Intel power consumption pre-Cannonlake. Mac doesn't have a touchscreen at its price point...
My gut ultimately says: NOPE.JPG
General hope is for GPU Docks like the Razer Core to come to Apple in 2017. Thoughts?5 -
Woo time for a Chromebook rant against Samsung!
So they just 'revised' the Chromebook plus (Currently using v1 to write this) and I was intrigued because they ditched the Samsung made ARM chips for an intel CPU.... Buuuuuuuuuut... It's a fucking celeron... Of all fucking things to put in a half thousand dollar laptop, at least an m3 would be useful. Then I find out they are ditching the full metal body, it's heavier, thicker, same 3GB of RAM, ditching the 3:2 aspect ratio (Fucking why?!) and the 'upgraded' keyboard doesn't even have back lighting...
Ugh, makes me want a pixel book more, double the price and a million times the performance and quality -.-5 -
*rewrites rust mpsc*
you did it wroooong
I thought my threads were locking if I had thousands of jobs spawning thousands of more jobs. turns out it's fine. actually if I organize my data locks in the way everyone wants to do them my CPU fans go off but my original way you don't feel jack shit and processes faster
turns out it's because 320k jobs is a bit much for mpsc. because my jobs can spawn more jobs the whole thing just grinds to a halt. and there's sync-mpsc which allows you to have a maximum number of data you send through it, therefore I can just have 245 sent jobs instead of 320k but then this locks all the threads because for a thread to finish it needs to finish sending jobs, but a sync mpsc won't let you send a job if current jobs are over the specified limit. so all the threads get stuck sending jobs. smart. not. what's even the point of that?!
and evidently there's no built-in way to prioritize certain jobs. the AI thinks you should just send jobs in and each thread should have a priority queue. I don't know sounds dumb to me. then you could by random luck have threads with lots of jobs that need to be prioritized to be done and other threads stuck hanging waiting for previous jobs / the other threads. no thanks
so clearly the solution is to rewrite mpsc but allow prioritization when a thread goes in to ask for a job to do
since my jobs are intended to start other jobs, it makes sense to have no actual upper bound limit to the number of jobs in the queue but to favour doing jobs that won't start new jobs to lower the RAM and compute necessary to juggle all this
hope this is the actual problem. cuz the code works for like 200 jobs spawning 500 jobs each, which is 100k jobs total
but it stalls to a halt doing 8300 jobs spawning 500 jobs each (which if I do the math -- in my tests it stalls at 320k jobs and seems the number should be 4,150,00 jobs -- yeah I think this is probably the damned problem)8 -
So I have a question to anyone familiar with the General Transit Feed Specification...
Why is the data provided in text files? Is there not a way to format the data to allow for random access to it?
Like I'm currently writing a transit app for a school project, and as far as I can tell, the only way to get all specific stops for a route, is to first look up all trips in a route, then look up all the stopids that are associated with a trip in stoptimes.txt (while also filtering out duplicates since the goal is to get stop ids, not specifically stop times) and then look up those stop ids in the stops.txt file.
The stoptimes file alone is over 500000 lines long, unless there is a way better way to be parsing the data that I'm not aware of? Currently I'm just loading the entire stoptimes file into a data structure in memory because the extra bit of ram used seems negligible compared to the load times I'm saving...
Would it be faster if I just parsed all the data once and threw it into a database? (And then updated the database once a month when the new data comes in?)3 -
grrrr
last week my laptop died out of nowhere. it stopped recognizing the one drive in it. I lost a bunch of files, code. evidently ssds fail out of nowhere unlike hdds which slow down and error all the time before ultimate failure
my warranty for this 4k$ laptop expires in 12 months and this was month 13. nice. I don't like warranties anyway, and the site said they would replace things with "comparable hardware, sometimes refurbished" wtf no thanks
so I found some guides of people upgrading the drive in this laptop. seemed easy enough, unlike older laptops from back when I was in school where you had to take out 12 things first to get to anything
unfortunately I needed a specific screwdriver. I walked several miles to the nearby hardware store thinking they would have said screwdriver. the old guy in the basement said there was a kit where it started from t4 (I needed t5), but he had just sold out his last one. I checked their online store with a friend for a while on my way back home and we kept finding torx screws but the wrong sizes. fuck.
he said screwdrivers this small are only used for electronics, asked if there's any other hardware stores and there aren't near me
however it occurred to me this strip mall has a lot of suspicious computer stores on it. so I walked back up the street looking for one.
found one with a suspicious poster, saying it was an internet cafe but the last point on their poster said they do repairs. walked in. nobody is in there, suspiciously 2 desks with old computers all empty, then you go forward in this dark cave, with plastic wrapped implements on the walls, you finally find a glass shield and behind it was a meek Asian man that took me a moment to notice
I asked him if he had t5
he handed me a plastic baggy full of tiny screwdrivers, for me to take one
I asked if they're t5
the shape looked right, but I can't tell the size
I took one out and tried to find size marking, but nothing
he didn't seem to know what I was asking when I asked about its size
he said if it's wrong I can come back and trade what I took for another. lol
I asked him if I can buy it, since that wasn't evident to me due to how sus this random bag of screws is being thwarted on me lmao
he said 5$ cash
I gave him a fiver
this sus shop literally avoiding taxes lmao
walked back home, ate food cuz starving, tried the screw and FUCK, it's too big. put laptop in a bag and hauled ass fast, checked on maps the store I got this from closes in a few minutes so I really wanted to make it there because what if the receptionist changes and they don't know I took this screw. I got no receipt
got there right before closing, put my laptop down, said it was too big. he used a few screws until he found one that fit, said I could try it and I did (so scam aware!). bingo bango. now I got a screwdriver that fits the laptop.
walked home, sat down and took apart the laptop. been a few years since I did so. the hardware inside looks entirely unrecognizable to me. started cycling through YouTube videos of laptops of the same name as mine, but their insides don't look like mine. is this ram? is this the NVMe? what the fuck is anything?
finally found a video guide where the guy was quite informative. not the same laptop but he's informative enough I figure it out. ram and drives are so different and weird now. took parts out, put them back in, rebuilt laptop, tried to boot, same problem. jiggling parts like this works with desktops often, guess not with a failed NVMe
so I'm screwed. get on Newegg and bought a new NVMe. should arrive in 3 days via Purolator
yesterday was day 3. it was at a sort facility near me, then out on delivery, but nobody ever came. then it went back to sorting. now it's out on delivery again. I'm sitting here thinking that's a little weird, wasn't Purolator the delivery company that had me go 2 hours outside of town to pick up a 15lb desktop case once?
... and then I looked up Reddit comments... then reviews on the purolator facility it's at... I am screwed. last time iirc they were out for delivery for 3 days, never tried delivery, then on the last day at the end of day they stated they attempted delivery but no go. that was bullshit. then it ended up at that facility. which takes 2 hours to fucking reach.
the reviews are so bad... the facility has 1.2 star reviews with thousands of them. they won't leave even a stub, then seem to not know where your package is at the facility, or they deny you have the right to pick it up despite ample IDs, or someone ELSE picks it up and it's not there. they also ship your package back after 5 days, so if they don't leave a note and you miss it tough luck...
fucking hell
also rumours that they just hire "contractors" in normal cars to drop off packages? wat? lol
AND EVERY REVIEW HAS A BOT COMMENT. THEIR SUPPORT IS JUST A CHATBOT
I thought this was just a small hiccup
I think I might not have a drive for weeks now
fucking hell
now I'm sitting on my porch2 -
I'm a full stack developer, I have been using windows all my life but I purchased a new laptop recently, it has only 4gigs of RAM and I will upgrade it in the future but that's gonna take a while but mean while its running windows and its a pain in the ass! Memory is always almost full, disk(HDD 5400rpm) usage is 100% when I don't expect it to be. Chrome and VSCode hogs my memory and the laptop lags like crazy because of that webstorm and pycharm are all out of the question. I'd like to switch to a Linux distro, dual boot it since my windows is a genuine copy. Which Linux distro would be the best for me?9

Folks
I need your input on the following
how important do you think having high core count in CPUs in your daily workflow?
I'm planning on buying a new ryzen 5000 processor, while I am going to game the hell out of it I'm also planning to run wsl2, a ton of chrome tabs, maybe have multiple IDEs for developing random stuff, maybe some virtual machines for some experimentations, some docker containers for some selfhosted software and lastly open demanding games while having everything else open.
Will a 6 core 5600x be enough? or do you think investing in a 5900x will be worth it down the line? (lets say for the next 7 years)
Assume that the GPU will handle the games im going to play and the RAM is going to be 32gb for now11 -
One year after planning, ideation, development. We were finally ready to launch our client’s product. Everyone was super excited to finally be done with the project. I was responsible to launch it, on a Monday, overnight.
Launch successful. Everyone is happy.
But then it happened... we got the call.. the application is not working. Our team started working to figure out what may have gone wrong, error logs weren’t useful, Application monitors were calm.
Finally, after a tiresome 24 hours, I logged into the hosting account of our client, and there it was, in big bold letters, “Ram: 512MB”.
Apparently, our client thought it would be best to get a cheaper dedicated server instead of the one we fucking recommended.2 -
Using grafana together with tinc+promotheus, has been a blast.
Initially I wanted to get into ELK with Kibana and all that, but that required 8G of ram, the instructions to get it running in the open source "mode" was nearly non-existent, together with all the ready docker compose stacks out there simply not working or the images being broken.
I'm sure I could've managed around most of those issues, but the fact it is as hungry as gitlab, made it a literal no-go for the usual server resources my clients host or my own scaled down server recently.
Thankfully I remembered that there's grafana and me having experimented some time ago with tinc, so I can have very lightweight beat'esque prometheus agents deployed listening on tinc local net only, with the typical nginx auth and some whitelists to all of the servers I host and all those of my clients.
The dashboard creation was especially great in grafana (tbf promotheus does actually most of it), literally what I always wanted out of those "complicated" solutions, that do it all, but have no proper query language, complex documentation, heavy collectors with no properly named data points, expensive resource runtimes, ..
with grafana I can just easily put dashboards into folders, create users to look only at certain stats or even dashboards (opened up some interesting contracts actually, because now I can also offer proper monitoring for all things delivered), easily drag and drop around stuff to fit more information (most others fix you to a small 3x2 grid, a too big grid for a TV or simply non resizable tiles, making that one counter take up an entire row) and resize to my hearts desire
tinc of course allows me to easily create private networks that are resistant to failure across any region and the routing is done for me, so I don't have to run around it all that much either
P.S: a damn tiny fly went into one of my now 4 monitors and died right in the middle, because I thought it's just some dirt and I pressed it in while trying to wipe it off, so that monitor now serves as the top most on a vesa mount5 -
What tools do you have access to at work?
I don't work a tech company, far from it. I love it but both the hardware and software at my disposal are so shitty I'm starting to lose it.
Running Windows locally, I'm not allowed any Linux distro because "security." Indeed, I don't even have admin rights on my machine. It was rejected. The excuse being that I am sudoer on a server, which (and can only be) physically located in our headquarters.
Today I found out this server's CPU from the dark ages does not support tensorflow, so here I will be building that shit from source tomorrow (no GPU of course).
And thanks for 4G of RAM on what you refer to as a "power" machine.3 -
Know that feeling when you break out of a really deep relationship, end up with someone else who's prettier and better in many ways than your ex yet still, during those intimate moments, you can't help but think about your ex and how good life was with them?
My previous laptop even though it had the same processor, lesser RAM, was less prettier and the SSD being the only upgrade to my new one, somehow worked faster, smoother and felt a lot better. :( -
First issue with Manjaro. I am not sure when it begun, but now, every single time linux uses the SWAP file, the entire system stays unresponsive, freezing (not even the mouse moves), so I need to wait until it finishes using the SWAP to be able to use it again.
I have 16GB RAM and I was not noticing that, but for some reason, Chromium started to use a little bit of the SWAP when the Hardware Acceleration were turned on and the mouses started to stop moving for a few ms/seconds.
So I tried it out: opened a VM with 8GB RAM and done, my PC were frozen for about 10 minutes, until I were able to use it again.
When I turn on the swap file, everything works fine again, even the VM. It does not matters with the SWAP is on a SSD or not.12 -
Need some help choosing a laptop (budget is up to 2000 EUR)
Initially 6 months ago I bought Dell G5 (5587) for 1300 EUR and it had i7 8750H CPU, 6GB NVDIA GeForce GTX 1060 Max-Q GPU, 16GB RAM, 256GB SSD+1TB HDD.
However turned out to be a piece of shit because dell fucked up their thermal management badly and they don't give proper access for their users to control the fans. Even when you force fan control via Windows test build then you will face a dissapointment since most games won't run properly on Windows test mode. So anyways I got rid of that laptop. For more info you can have a look here https://dell.com/community/... and there are dozens of topics on reddit about that.
So yeah currently looking for a decent gaming/movies/coding laptop which gives full access to undervolting/fan control.
Currently I'm looking into Razer Blade 152 -
based on my previous rant about dataset I downloaded
https://devrant.com/rants/9870922/...
I filtered data from single language and removed duplicates.
The first problem I spotted are advertisements and kudos at movie start and at end in the subtitles.
The second is that some text files with subtitles don’t have extensions.
However I managed to extract text files with subtitles and it turned out there is only 2.8gb of data in my native language.
I postponed model training for now as it will be long, painful process and will try to get some nice results faster by leveraging different approach.
I figured out I can try to load this data to vector database and see if I can query it with text fragment. 2.8gb will easily fit into ram so queries should be fast.
Output I want is time of this text fragment, movie name and couple lines before and after.
It will be faster and simpler test to find out if dataset is ok.
Will try to make it this week as I don’t have much todo besides sending CVs and talking with people.2 -
How much ram do you generally need in a Linux server? I'm already using 70% out of 2GB on my LAMP stack, and I'm planning to deploy my website prototype to show off in interviews next year. Is 8-16GB of EEC RAM a better option for future proofing? The only thing holding me back is I don't plan to make money on this server in the immediate future so I'm trying to weigh the pros and cons. 🤔
This CentOS server runs on CLI only so the GUI isn't a factor. Eventually I'll have it host Java Spring API's which will easily take up what RAM I have left. On top of that I have 10 db on mySQL so that's another likely culprit.7 -
Bullshittery continues. This time around, absolutely innocent, clamav is root cause. For once not incompetent idiot, but piece of software. IDK if that makes me happy or upset.
So our email server that I configured and took care of died. RIP. Damn, better put it back together ASAP. So Im under pressure, while still pissed at everything that I ranted before (actually my last 2 rants were throttled, and in total all of that happened past 60 minutes but devrant rate limiting) I start auditing logs. You imagine, we kindda need it NOW, and it's second time last month clamav is pulling stunts and MTA refuses (properly) to work without antivirus. So pressurized, I look at logs, what the fuck went wrong.
clamav deamonize() failed - cannot allocate memory
Hmm. Intresting, but sounds like bullshit. I know server is quite micro becouse they wanted to save on costs as much as possible, but it has well over half a gig free ram just before it crashes (like 800MB) with that message. Is it allocating almost gig in one call or what? Looked carefully at trusty htop while it was starting, and indeed, suddenly it just dies with quite a bit of ram free, almost as much as it weights already. And I remember booting it up when I was configuring it, and it had fair bit of headroom.
Google, help me friend... Okay, great, so apparently at some point clamav loads virus DB into ram (dafuq?), and than forks, which causes spike of 2x the ram usage, and than immidietely frees it up.
Great, that sounds like great design decision... At least I know, I can just slap on SWAP file, restart it and call it a day.
It worked, swap file is almost empty (used 15megs, 900 megs free ram, whatever).
That leaves me wandering, who figured out to load DB to ram? That means pretty much that clamav will eat a little bit more ram each vir db update, and that milisecond "double ram" spike will confuse innocent people who just wanted to run clamav and it worked last *long period of time* and now crashes without warning without any changes to configuration.
Maybe there is logical explanation, I want to know it.8 -
Part number idk of TheCapeGreek's Ship of Theseus:
PC dying again. Either now all 4 of my (admittedly old) RAM sticks are dead within 3 weeks of each other or the motherboard is conking out. Either way I need to finance a new rig on Black Friday. At least I have a working hard drive and 2 monitors.3 -
I drank two pots of coffee and am now paranoid. I want to do memory test of my new ram. So I am going to use memtest from https://memtest.org/ . Out of paranoia I decide to test with VirusTotal. It passes 68 out of 70 tests. 2 say its bad. Windows Defender says it is fine. I usually just rely on Windows defender. I test with another site and it says it is clean. But is it really clean? Why do so many assholes ruin a good thing? Scammers and blackhat hackers are scum.4

I was so bored the other day, that I wrote a fat client in C# to calculate happy numbers. I used BackgroundWorker class, because I was hoping to be able to cancel the calculation process. It turned out I couldn't. Rats.
Out of pure frustation, I wrote the same program in Java using Swing and SwingWorker. Here, the cancel feature worked just fine.
And then I had this "Wait ... What?!" moment, when I realized, that one of the programs was incredible slow. So I rewrote both codes, so that they used the same algorithm and similar classes. I compiled the C# program as release and ran it stand-alone, while I started the Java application from within the eclipse IDE.
The C# program needed 42.681 seconds for 100,000 happy numbers, while the Java application completed the same task after 0.986 seconds. The result sets of both programs are the same.
Maybe I need a new PC (2007, 64 bit, 8 GB RAM, Windows 10). Or I'll get rid of C#.9 -
My PC just stopped working and I can't figure out why. There's absolutely no feedback to pushing the power switch. I feel like I tried everything the internet recommends, made sure the button works (it does, and so do the connected pins on the MB), held it down for a minute with the PSU unplugged, shorted the power pins manually, re-plugged all the cables, changed the CMOS battery, tried turning it on with just one RAM stick at a time.
I'm out of ideas.12 -
TL;DR: Embedded software guy needs to create a multi-instance sandbox environment in Jenkins for testing and not sure what good solutions are out there. Looking for suggestions.
So at work, we have these really cool integration tests that validate our system for flight safety. What's not so cool is that due to factors outside of my control, each test has to be run serially and the entire test suite can take many many hours. This is mostly due to a hardware limitation (not enough physical NICs), but there are other SW factors as well.
What I would like to do is somehow be able to wrap up all the resources into a neat little package and then deploy that package into some kind of virtual environment that can be instantiated on a Jenkins job. The NIC issue would be replaced with a virtual one and *theoretically* I should be able to spawn as many instances of this virtual environment as my CPU and RAM can handle. In short, I want to pseudo parallelize our test suite and drive down our testing time. Somehow I would need to be able to control this entire thing from a script of some sort.
Does anyone know of something out there that would satisfy these kinds of requirements? Double internet points if it's open source. -
I'm fucking tired of my computer having random
2 seconds latency on any basic action and being slow as fuck regardless of powerful processor, ssd and 32GB RAM. Music via bluetooth is basically unusable since every few seconds the music stops for a 0.2s then plays again. I installed this system (opensuse tumbleweed) in February this year and it's just sad that I have reinstall again (any ideas for distro) ?
I made a dummy mistake of buying a CPU without internal graphics and this resulted in having to buy a GPU. So I got myself Nvidia(another mistake) since i though i would be using CUDA on the university. Turnes out CUDA cannot be installed for some retarded reason.
With Nvidia GPU the screens on my two monitors are swapping every time I use a hdmi switch to use other computer. On AMD GPU this problem does not exist. AMD GPU pro drivers are impossible to install. Computers barely fucking work, change my mind. Shit is breaking all the time. Everything is so half assed.
The music player that i use sometimes swaps ui with whatever was below it like for example the desktop background and i need to kill the process and start again to use the program. WTF.
Bluetooth seems to hate me. I check the bluetooth connected devices on my computer, it says headphones connected. BULLSHIT. The headphones are fucking turned OFF. How the fuck can they be connected you dumbass motherfucker computer. So I turn on the headphones. And I cannot connect them since the system thinks that they are already connected. So I have to unpair them and pair them again. WTF. Who fucking invents this bullshit?
Let's say i have headphones connected to the computer. I want to connect them to phone. I click connect from the phone settings. Nothing happens. Bullshit non telling error "could not connect". So I have to unpair from computer to pair to phone. Which takes fucking minutes, because reasons. VERY fucking convenient technology.
The stupid bluetooth headphones have a loud EARRAPE voice when turning them on "POWER ON!!! PAIRING", "CONNECTED", "DISCONNECT". Loudness of this cannot be modified. The 3 navigation buttons are fucking unrecognizable so i always take few seconds to make sure i click the correct button.
Fucking keyboard sometimes forgets that I remapped esc key to caps lock and then both keys don't work so i need to reconnect the keyboard cable. At least it's not fucking bluetooth.
The only reason why hdmi switches exist is because monitor's navigation menus have terrible ui and/or infrared activated, non-mechanical buttons.
Imagine the world where monitors have a button for each of it's inputs. I click hdmi button it switches it's input to hdmi. I click display port button - it switches to display port. But nooo, you have to go through the OSD menu.
My ~ directory has hundred of files that I never put there. Doesn't feel like home, more like a crackhead crib.
My other laptop (also tumbleweed) I click on hibernate option and it shuts down. WTF. Or sometimes I open the lid and screen is black and when i click keyboard nothing happens so i have to hold power button and restart.
We've been having computers for 20 + years and they still are slow, unreliable and barely working.
Is there a cure? I'm starting to think the reason why everything is working so shitty and unreliable, is because the foundations are rotten. The systems that we use are built with c, ridden with cryptic abbreviated code, undefined behavior and security vulnerabilities. The more I've written c programs the more convinced I am, that we should have abandoned it for something better long ago. Why haven't we? And honestly what would be better? Everything fucking sucks. The rust seems to be light in the tunnel but I don't know if this is only hype or is it really better. I'm sure it can't be worse than c or c++. Either we do something with the foundations or we're doomed.22 -
This question might make you lose a brain cell because of stupidity in the question. Read with caution
Is there a way to compile a game for Windows from Linux in Unreal engine? I did google some posts but the answer was either use a Virtual machine which will not be done or use the the theoretical method of using mingw but the forum posts state that it will be tricky business or use a windows machine. I have dual booted windows with linux on my machine.
However since the machine has a 512 gb ssd most of the storage space is devoted to unreal engine which takes 47 gigs in itself and have a lot of programs installed I have a usable 20 gigs left out of 145 gig partition. Windows has around 318 gigs of storage to it but I have 100 gigs free at most. So after installing the windows sdk, visual studio with extensions, unreal engine and some other stuff I don't have much space left for myself. I need that much space since I install a lot of games to my ssd. So now I cant load my bigger projects for playing on my windows. I could use my hdd which is mostly used for backups and 100+ gig stuff. Though the hdd's are of course far slower than ssd's which shouldn't be a problem however last time I used visual studio it ate more than 2 gigs of ram for a solution meaning that the compiler has very low memory for itself to actually compile so for any large files the hdd has more of a bottleneck.
Oh and I can't upgrade my ssd's or ram because I don't have enough money.
Thanks for the answers in advance4 -
spent a few days trying to track down the cause of a thermal shutdown in my workstation. intel 4790k with no overclock would spike to 95C on one core (core1) whenever maxing out all 8 threads, be it real work, mprime, anything with 100% cpu being used. I quadrupled my RAM from 8gb to 32, because its cheap and id like to have all data in memory sometimes, not because I thought that was the problem. I reseated my watercooling block. I checked out the PSU. I unplugged all unnecessary peripherals, drives, etc. It turned out to be a bug in Gigabyte MOBO BIOS (causing temps to be read incorrectly i think, still not exactly sure...) updated from version 5 to 10 and poof now temps are back in the high 50's at full load. it only took 2 days to figure out and i think i learned something

When your laptop runs out of ram due to your environments and it begins writing to swap. Your hard drive fails resulting the computer to crash and restart -_-.

hey everyone like a the past few months i got my laptop but now im planing to get a mac just for the sake on developing ios apps more on practice and by far project execution like a mid level project the question is will the new macbook air(2018) the one with the i5-y proci do good in terms of development? my options are entry level only mainly for swift and react-native dev
Options:
MBA 2018
RAM 8gb
SSD 256gb
i5(Amber Lake-Y 7 W Dual-Core)
or
MB Pro 2018

i5(7th-generation)
please help me out since im planing to get it later, thanks3 -
Ram drives are a very good and useful thing why has no one made a nice ram drive caddy using laptop ram, the speeds on the older ram and drives out do any drive on the market and the unit is not a lot to make, I happy to put some old DDR 2 ram a new life as a USB ram drive using as a page or swop drive or Live CD Drive.
Or am I missing something and they really hiding somewhere, the ram drives I seen are stupid price and offer functions we don't need or aimed at big server companies but this would really help privacy, or better still anyone know if we can make some kind of ram drive with maybe a maker board and laptop ram ?1 -
//not a rant
In Semptember I will be attending information technology at university, and I was wondering what kind of laptop should I buy:
optimal screen size? (13.3 or 15.6)
ram? (for VMs)
processor?
dedicated graphics? (or should I just stick to integrated)
I will be mainly coding, running VMs and school stuff(maybe some casual game like League or Minrcraft), so I was wondering if you guys could help me out with the decision18 -
I have a laptop with 8gb ram, 1Tb HDD, i5 7th gen running windows 10 and Ubuntu. Right now I'm using windows 10 as my primary OS, I'm simply addicted to the gestures especially the four finger swipe to switch desktops. I have been thinking of adding an SSD to the mix and my budget only permits a 120gb M.2 or a 250gb normal ssd.
The advantage with m.2 is that I can keep my HDD and boot my OS from the ssd and maybe install my IDEs on there but with the other ssd I'm gonna have to take my HDD out and use it as an external.
I read somewhere that 250gb above SSDs are the ones worth spending money on and that the 120 and 250 doesn't justify the price or life.
So my question is, should I go for an SSD? and if I do which one to go for m.2 or the normal one?3
