https://git.kernel.org/…/ke…/... sure some of you are working on the patches already, if you are then lets connect cause, I am an ardent researcher for the same as of now.
So here it goes:
As soon as kernel page table isolation(KPTI) bug will be out of embargo, Whatsapp and FB will be flooded with over-night kernel "shikhuritee" experts who will share shitty advices non-stop.
1. The bug under embargo is a side channel attack, which exploits the fact that Intel chips come with speculative execution without proper isolation between user pages and kernel pages. Therefore, with careful scheduling and timing attack will reveal some information from kernel pages, while the code is running in user mode.
In easy terms, if you have a VPS, another person with VPS on same physical server may read memory being used by your VPS, which will result in unwanted data leakage. To make the matter worse, a malicious JS from innocent looking webpage might be (might be, because JS does not provide language constructs for such fine grained control; atleast none that I know as of now) able to read kernel pages, and pawn you real hard, real bad.
2. The bug comes from too much reliance on Tomasulo's algorithm for out-of-order instruction scheduling. It is not yet clear whether the bug can be fixed with a microcode update (and if not, Intel has to fix this in silicon itself). As far as I can dig, there is nothing that hints that this bug is fixable in microcode, which makes the matter much worse. Also according to my understanding a microcode update will be too trivial to fix this kind of a hardware bug.
3. A software-only remedy is possible, and that is being implemented by all major OSs (including our lovely Linux) in kernel space. The patch forces Translation Lookaside Buffer to flush if a context switch happens during a syscall (this is what I understand as of now). The benchmarks are suggesting that slowdown will be somewhere between 5%(best case)-30%(worst case).
4. Regarding point 3, syscalls don't matter much. Only thing that matters is how many times syscalls are called. For example, if you are using read() or write() on 8MB buffers, you won't have too much slowdown; but if you are calling same syscalls once per byte, a heavy performance penalty is guaranteed. All processes are which are I/O heavy are going to suffer (hostings and databases are two common examples).
5. The patch can be disabled in Linux by passing argument to kernel during boot; however it is not advised for pretty much obvious reasons.
6. For gamers: this is not going to affect games (because those are not I/O heavy)
Meltdown: "Meltdown" targeted on desktop chips can read kernel memory from L1D cache, Intel is only affected with this variant. Works on only Intel.
Spectre: Spectre is a hardware vulnerability with implementations of branch prediction that affects modern microprocessors with speculative execution, by allowing malicious processes access to the contents of other programs mapped memory. Works on all chips including Intel/ARM/AMD.

My first job: The Mystery of The Powered-Down Server
I paid my way through college by working every-other-semester in the Cooperative-Education Program my school provided. My first job was with a small company (now defunct) which made some of the very first optical-storage robotic storage systems. I honestly forgot what I was "officially" hired for at first, but I quickly moved up into the kernel device-driver team and was quite happy there.
It was primarily a Solaris shop, with a smattering of IBM AIX RS/6000. It was one of these ill-fated RS/6000 machines which (by no fault of its own) plays a major role in this story.
One day, I came to work to find my team-leader in quite a tizzy -- cursing and ranting about our VAR selling us bad equipment; about how IBM just doesn't make good hardware like they did in the good old days; about how back when _he_ was in charge of buying equipment this wouldn't happen, and on and on and on.
Our primary AIX dev server was powered off when he arrived. He booted it up, checked logs and was running self-diagnostics, but absolutely nothing so far indicated why the machine had shut down. We blew a couple of hours trying to figure out what happened, to no avail. Eventually, with other deadlines looming, we just chalked it up be something we'll look into more later.
Several days went by, with the usual day-to-day comings and goings; no surprises.
Then, next week, it happened again.
My team-leader was LIVID. The same server was hard-down again when he came in; no explanation. He opened a ticket with IBM and put in a call to our VAR rep, demanding answers -- how could they sell us bad equipment -- why isn't there any indication of what's failing -- someone must come out here and fix this NOW, and on and on and on.
(As a quick aside, in case it's not clearly coming through between-the-lines, our team leader was always a little bit "over to top" for me. He was the kind of person who "got things done," and as long as you stayed on his good side, you could just watch the fireworks most days - but it became pretty exhausting sometimes).
Back our story -
An IBM CE comes out and does a full on-site hardware diagnostic -- tears the whole server down, runs through everything one part a time. Absolutely. Nothing. Wrong.
I recall, at some point of all this, making the comment "It's almost like someone just pulls the plug on it -- like the power just, poof, goes away."
My team-leader demands the CE replace the power supply, even though it appeared to be operating normally. He does, at our cost, of course.
Another weeks goes by and all is forgotten in the swamp of work we have to do.
Until one day, the next week... Yes, you guessed it... It happens again. The server is down. Heads are exploding (will at least one head we all know by now). With all the screaming going on, the entire office staff should have comped some Advil.
My team-leader demands the facilities team do a full diagnostic on the UPS system and assure we aren't getting drop-outs on the power system. They do the diagnostic. They also review the logs for the power/load distribution to the entire lab and office spaces. Nothing is amiss.
This would also be a good time draw the picture of where this server is -- this particular server is not in the actual server room, it's out in the office area. That's on purpose, since it is connected to a demo robotics cabinet we use for testing and POC work. And customer demos. This will date me, but these were the days when robotic storage was new and VERY exciting to watch...
So, this is basically a couple of big boxes out on the office floor, with power cables running into a special power-drop near the middle of the room. That information might seem superfluous now, but will come into play shortly in our story.
So, we still have no answer to what's causing the server problems, but we all have work to do, so we keep plugging away, hoping for the best.
The team leader is insisting the VAR swap in a new server.
One night, we (the device-driver team) are working late, burning the midnight oil, right there in the office, and we bear witness to something I will never forget.
The cleaning staff came in.
Anxious for a brief distraction from our marathon of debugging, we stopped to watch them set up and start cleaning the office for a bit.
Then, friends, I Am Not Making This Up(tm)... I watched one of the cleaning staff walk right over to that beautiful RS/6000 dev server, dwarfed in shadow beside that huge robotic disc enclosure... and yank the server power cable right out of the dedicated power drop. And plug in their vacuum cleaner. And vacuum the floor.
We each looked at one-another, slowly, in bewilderment... and then went home, after a brief discussion on the way out the door.
You see, our team-leader wasn't with us that night; so before we left, we all agreed to come in late the next day. Very late indeed.9 -
Dells XPS are made of magic. [long story, major fuckup, 10k+ damages]
It all started in December. One morning I was late to work, drove there as fast as possible. (I live like 3 minutes away so me being late really meant *late*) Parked my car in a secluded car park, grabbed my backpack and ran to work. The car park is like 100 meters away from work so I took my feet into my hands and ran. Next thing I know my heels loose all grip while I go down a small slope and I drop on my back full force. On a sharp edged stone. With only my 1700$ XPS in it. Fuck.
I paniced, but got up and ran to work. I checked on the notebook, praying it would boot. It booted! Holy shit. I flipped the notebook and saw two small dents in the aluminum shell. I was thorougly impressed. I later discovered that it left a small shadow on the display, but given what a hit that was (I am not exactly a lightweight), impressive would be a massive understatement.
Fast forward to February, I am weighing my options to get the screen replaced maybe, as damage on my hardware (even if neglectable) triggers some sort of OCD and makes me feel bad 24/7. Also my laptop tends to shut off from time to time, looked into the Event Viewer and saw kernel panic. I figured that the battery probably still took a hit and that it drops voltage from time to time and the kernel assumes a critical situation, thus shutting off.
It stayed quite snowy in Austria up until March, so occasional snowing wasn't rare. Got out of work one day, saw it snowed a bit. Whatever. I had my moms car at the time, so I tried if it would slide a bit if I donut on the now (5pm) empty parking space. Nothing. Drove done a small hill, ABS triangle lit up red (board computer can't outbalance the snow). I drove out to the main street where everything was salted and drove along towards my house. Took a turn into my street, accelerated for a bit and then went off the gas so the car would smoothly drive along with the speed slowly degrading. So I went off the gas and noticed I was a bit to the right, no wonder, centrifugal forces.
*steers left*
"Huh seems like I need a bit more"
*car still doesnt move much*
"What the- go to the left!"
*steers left hard*
"Fuck that wall is coming closer"
*Breaks*
*car doesnt break*
"FUCK FUCK FUCK FUCK!!!"
Everything got quiet in seconds, me waking up to an open airbag, ripped pants, a hurting wrist, the radio somewhere on the ground and fumes that smellt like burning wires. I grabbed my backpack that was now somewhere on the floor instead of on the seat and ran outside, tears in my eyes and the phone on my ear calling my mom. I walked inside as she walked outside, hearing a weeping scream that I haven't heard from her since I am alive. While walking inside I noticed my backpack was wet on the bottom, my 2 litre water jug shattered when my backpack hit the dashboard. I tried to stay calm and act rational, knowing that every second counts when It comes to water damage. I hastely searched for some rice and a bag to put my laptop into, stuffed the bag with both and went outside. The car was totaled, my mom pissed and crying. And I was in shock, sad, angry and hurting.
I kept the laptop on my heater for a few days, bagged in rice. I dared to try a boot after a while and you wont believe me, it fucking booted. Even the keyboard backlight worked, just the screen was obviously broken in the back (no color distortion or bad pixel rows though!!) and the aluminum shell had a dent on the front. I talked with Dell Support a few days later, asking if it would be ok to open the XPS up so I could drain all of the water. She said yes thats fine, as long as I dont touch anything or screw around with it.
She said I can send it in and get it checked, but the pickup and analysis will cost 150$ and I can go from there.
I sent it in and estimated that, because battery, screen and other things probably needed changing, it will be around 900$.
Got a call a few weeks later:
"Hello beggarboy, the repair team reported back to us and said that they will have to replace everything, which will be 1700$."
"Fuck... Buying a new one is cheaper.."
"Yeah I know I am sorry about that, I can offer you a voucher so you can buy a new one for 250$ off if you would prefer that"
"Sorry but I will need some time to consider"
"I understand."
The agent clearly noticed I was bummed about it.
After going back and forth what to do I got another call a few days later.
"Hello beggarboy, we talked a few days ago. I have good news"
"Hello, yes, speak up?"
"I was able to get a special offer for you after putting in a few words..."
The next thing she said seemed unreal to me.
She was able to cut 600$ (!!!), making the new offer 1100$, instead of 1700$ or a new one for 1500$. I figured the reason she probably did that was because I am always very polite with support members. Always.
My XPS is back and healty again.
Thank you for taking the time to read this.
Dells XPS are made of magic.13 -
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!

Modern software has gotten so bad that it even gets sluggish at times on late 2018 flagship devices. Slow, cheap hardware like is usually developers' and fanboys' excuse, particularly when it comes to Windows stuff? Like hell it is.
Software "engineering" has become so.. terribly inefficient. I'd dare any developer worth their salt to rewrite their program to make it work on an early 2000's machine. After all, those can run pretty advanced GUI's, have a reasonable amount of hardware (just think about how large a gigabyte of RAM really is) yet should be able to make for a reasonable limitation set.
Hardware limitations are the mother of optimization. Not every person on the planet has a 32-core Xeon workstation with 64GB of DDR4 RAM and a GTX Titan in it. Whether your application performs reasonably well on your machine shouldn't be the metric. Try deploying it on that laptop you tucked into a shelf years ago and reevaluate.. please.
And definitely you Slack!! Slacking off, is that what inspired the name of that pile of junk?! 😡26 -
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 -

Edit, gotta add this one: Cable porn3 -
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 -
Hi,
I'm not a ranty person so I never actually thought I'd post anything here but here it goes.
From the beginning.
We use ancient technologies. PHP 5.2, Symfony 1.2 and a non RFC complient SOAP with NO documentation.
A year ago We've been thrown a new temporary project. An VOIP app for every OS.
That being iOS, Android, MAC, PC, Linux, Windows mobile. With a 3 month deadline. All that thrown at 4 PHP developers. The idea being that They'll take it, sign the delivery protocol, everyone happy. No more updates for the app needed. They get their funds they needed the app for and we get paid.
Fast forward to today...
Our dev team started the year with great news that We'll most likely have to create a new project. Since the amount of new features would be far greater than current feature set, we managed to finally force our boss to use newer technologies (ie. seperate backend symfony4 PHP7+/frontend react, rest api and so on). So we were ecstatic to say the least. With preestimates aimed at a minimum 3 month development period. Since we're comfortable with everything that needs to be done.
Two days later our boss came to me that one of our most annoying clients needs a new feature. Said client uses ancient version written on a napkin because They changed half of the specification 2 weaks before deadline in a software made not by a developer but some sysadmin who didn't know anything. His MVC model was practically VVV model since he even had sql queries in some views. Feature will take 3 days - fixing everything that will break in the meantime - 1-2 months.
F*** it, fine. A little overtime won't kill me.
Yesterday boss comes again... Apparently someone lost a delivery protocol for a project we ended that half a year ago. Whats even better at the time when we asked for hardware to test we never got any. When we asked about any testing enviornment - nothing. The app being SEMI-stable on everything is an overstatement but it was working on the os'es available at the time. Since the client started testing now again, it turns out that both Android app does not work on 8.1/9 and the iOS app does not work on ios12. The client obviously does not want to pay and we can do little with it without the protocol, other than rewriting the apps.
It will take months at least since all of those apps were written by people that didn't know neither the OS'es nor the languages. For example I started writing the iOS one in swift. Only to learn after half of the development time, that swift doesn't like working by C Library rules and I had to use ObjC also. With some C thrown in due to the library. 3 unknown languages, on an unknown platform in 3 months. I never had any apple device in my hand at that time nor do I intend to now. I'm astonished it worked out then. It was a clusterf**k of bad design and sticking everything together with deprecated apis and a gum. So I'll have to basically fully rewrite it.
If boss decides we'll take all those at the same time I'll f***ing jump of a bridge.8 -
So, there is this guy whose arguments on "How Apple is bad" are
1) "while copying files in Finder, you don't see a speed graph (like in Windows)"
2) "MacBooks don't have a Touchscreen"
3) "it's slow"
4) "you can't play games (like GTA V)"
5) "having app menus always on the top of the screen instead of in every window makes no sense"
Arguments on "why Linux is bad":
1) "it's ugly"
2) no gaming (same as point 4 above)
3)... And other biased irrelevant shit
Yet his amazing old Windows 10 computer with the most recent Insider build has only a 65% chance of booting on the first attempt. Almost nothing works properly on his hardware yet he always blames something unrelated to him.
Recently I was having trouble with the workplace wifi (for few minutes I wasn't having full speed like he on the other side of the room had), and his reaction "aha, it's your macOS, never working".
Like wtf. I don't hate Windows or I don't love Linux, but I night hate him for being an arrogant cunt and I want to punch his face.8 -
Why does almost everyone act as if the world they live in is perfect, or is supposed to be perfect?
This is about approaching IT infrastructures, but goes way beyond IT, into daily lives.
Daniel Kahneman wrote about the "Econs" - a mythical creature that behaves according to rules and rational thoughts, that everybody is guided by, as opposed to Humans, who are irrational, intuitive and emotional.
My beef is with a wider perception, beyond economical analysis, profit, investment and so on.
Examples:
Organization A uses a 15 year old system that is crappy beyond description, but any recent attempt to replace it have failed. Josh thinks that this is a crappy organization, any problem lies within the replacement of that system, and all resources should be devoted to that. Josh lives in a perfect world - where shit can be replaced, where people don't have to live with crappy systems. Josh is stupid, unless he can replace that old system with something better. Don't be Josh. Adapt to the fucking reality, unless you have the power to change it.
Peter is a moron who downloads pirated software with cracks, at the office. He introduced a ransomware that encrypted the entire company NAS. Peter was fired obviously, but Sylvia, the systems administrator, got off easily because Peter the moron was the scapegoat. Sylvia truly believes that it's not her fault, that Peter happened to be a cosmic overgrown lobotomized amoeba. Sylvia is a fucking idiot, because she didn't do backups, restrict access, etc. Because she relied on all people being rational and smart, as people in her imaginary world would be.
Amit finished a project for his company, which is a nice modern website frontend. Tom, the manager says that the website doesn't work with Internet Explorer 8, and Amit is outraged that Tom would even ask this, quoting that IE8 is a dinosaur that should've been euthanized before even hatching. Amit doesn't give a shit about the fact that 20% of the revenue comes from customers that use IE8, what's more important to him is that in his perfect imaginary world everybody uses new hardware and software, and if someone doesn't - it's their fault and that's final. Amit is a fucking asshole. Don't be like Amit.
React to the REAL world, not what you WANT the world to be. Otherwise you're one of them.
The real world can be determined by looking at all the fuck ups and bad situations, admit that they happen, that they're real, that they will keep happening unless you do something that will make them impossible to happen or exist.
Acting as if these bad things don't exist, or that they won't exist because someone would or should change it, is retarded.10 -
Had 2 days of vacation. Theoretically (plus weekend, plus 2 days) 6 days.
Worked today… At Saturday.
Some administrators forgot to properly check bandwidth limitations....
*rolls eyes*
We had a major version upgrade of some server software at Monday.
Guess why I got called...
Of course it MUST be the software upgrade.
It couldn't be the new hardware that was setup 2 weeks ago and on which a lot of "important" VMs were migrated.
*eyes roll inside till only white is visible*
The even more annoying thing is that it wasn't that hard to figure out.
Looking at monitoring, we had spikes on 20 Gbit/s (roughly 2.x Gigabyte/sec - Ethernet) connection of some server at roughly 1.9 plus Gigabyte/sec.
IO latency spikes that made the graph look like a heartbeat EKG with severe tachycardia...
*additionally to white eyes starts cursing in reverse latin*
Incompetent admin answer: Booboo that can only be your fault - the developers must investigate.
Me (just a tad more polite): Meep Meep mother fucker, get your shit together. If the software would eat that much, the network would be a niece chunk of charcoal. Plus the time (sending instead of links to monitoring pictures… guess the lazy fucktard who's brain is a vacuum didn't even bother to check it)...
NOTICE SOMETHING?!
Incompetent admin: It starts at the same time. Always.
After wasting roughly another hour of time discussing with him, I just hanged up the video call.
Called someone I knew from the admin department and turns out that - drumrolls please - the incompetent admin was someone who got recruited 3 months ago…
*turning into antichrist*
I then had a not so polite discussion about how the only competent people could take days off (all except incompetent admin were on vacation) and the seemingly incompetent fresh recruit - who by the way NEVER mentioned this - was the only one left of the admin department. Which would be bad alone, but no - he even got the 24/7 emergency support role for the whole weekend.
Sometimes this company and HR especially notoriously drive me insane...
Guess next week there will be some HR barbecue.
But yeah. After a lot of raging around we nailed it down to the traffic of backups and could fix it.
Roughly 4 hours of analysis, communication, raging and hatred.
Just one hour implementing shit.

Fuck Apple sideways! (Wait for it, the original part begins)
HOW can a company that keeps on boasting about UX, to the point that last WDC they took more time speaking about a fucking kaleidoscope animation for their watch then about the whole changes to their MacBook's hardware, even consider putting that turd of a remote on market.
If you have an Apple Store in reach, I invite you to get up, flush, and go there. Try that atrocity that is the AppleTV, and laugh at how incredibly bad it is. Then do your best to refrain from burning the place down in your inevitable rage, that might cause you legal issues.
The previous AppleTV was fine, it was practically useless, but usable. But for some reason they decided a touchpad with low precision and no gestures was a good idea to put on a remote to a thing that will, due to its target audience, most likely be plugged into a fancy TV that has a 300ms lag due to fancy image processing. That thing gives no feedback, appart from visual, has so little precision that in a movie, the smallest step I've achieved was 5 fucking minutes, while being really fucking careful not to spoil the movie.7 -
Microsoft Office Sharepoint Server.
There is no technology on Earth that speaks worse of Microsoft than is this crap. Nothing they ever made (not even Comic Sans) is as bad as Sharepoint.
No proper editor. Everything is slooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooow. To run it you need a state-of-the-art server. There is no way to make the UI modern, as Sharepoint itself is built upon 1995 era HTML. Tables in tables in tables in tables in tables. And even if you do a web part that's readable, it will be wrapped in shit and presented to the client anyway.
It's so easy to break too. Most of the time I was just watching why the fuck it didn't work. Huge problem with caching as well. Deploying any change requires 10 minutes of manual labor.
I get why companies want to use it. Out of the box it's got quite a few very nice features, and aside from the problems setting it up, and hardware requirements, it works decently well.
But I won't come near it unless I'm paid 100$ per hour or starving to death.10 -
My mom's laptop is always on 80-90% CPU even in idle and it is obviously hella slow and I am the one who has to work with it usually (since my mom is too afraid to use any kind of technology and can't remember any of her passwords), I tried to solve it but I came to the conclusion that the problem is probably Windows 10 itself. Okay, the hardware is bad too but still.
I started thinking about installing Linux on it, but It's not my laptop and I do not want to mess it up and I never did it before.19 -
I fucking love HP.
Why, you may ask, given that I've ranted about their crap so many times now? Great question!
I love HP because every time I go to town on their hardware because yet again it got me infuriated somehow, I don't feel bad about it afterwards. Instead I feel oddly satisfied, liberated from another piece of crap from them. And besides, usually it's their or Acer's shitty hardware that gets me worked up anyway.
That said, fuck you HP. Filthy Microsucking pieces of shit.
.. anyway. I've just went around disassembling an old vacuum cleaner this morning, to liberate its 800W single phase AC motor. I'll probably have to underrun it with a step-down transformer but at e.g. 200VAC it should probably work no problem 🙂12 -

Every type of noise Trafic, Air, hardware, your breath if there is nothing! the software will cut your voice and send only a few parts.4 -
A colleague of mine had to debug performance problems in a foreign, proprietary application that is ancient.
To be crystal clear: Only reason that thing exists is because some old geezers fear change.
Asked me for help cause it's an _ancient_ MS SQL server that is luckily running on hardware owned by us.
Finding the credentials was already a funny task.
We had to access the vault (not joking here, we have a physical vault for storing sensitive data and critical backups), grab a folder and find the necessary data cause no one ever dares to touch that thing.
The application is btw for a sort of ERP / inventory system that is used in some ancient shops not yet migrated...
Yeah. Story speaks for itself.
Anyway, after dusting off ourselves, we were able to connect.
Was a bit ... Interesting. Everything's in german. The worst kind of german.
After looking at the first tables, I started giggling.
My colleague knew immediately that this was a sign of danger (insert Simpson meme here), raised his eyebrows and asked "How bad is it....".
Me, still giggling, "lemme take a further look, this is gold".
*long sigh from the colleague*
Well... It ended with me putting my hands in front of my eyes, turning around and saying: "I cannot look at it anymore, it hurts too much...."
To summarize:
- German table names
- When a table exceeded 300 plus columns, they added another table with the same plus suffix "_ddd"… where ddd is an zero filled integer sequence like 001
- To join this mess, they created views... Named "generator" - Sequence Number ... Some had the beginning of table names appended, which doesn't make it less confusing.
- the process list was listing queries running longer than 5 mins.
Which isn't at all surprising when generating carrtesian products of N tables with left join.
I've seen shit.... I've seen a lot of shit.
But that shit scared me.1 -
I find it annoying when non-tech savvy people criticize the Parler devs for using AWS because "it's Amazon they had it coming", I don't know the devs or company behind that website, I've never used it, but wtf man do you have any idea what's involved in building, deploying and maintaining a platform like that or any other similar? ffs you would barely be able to write an HTML blog by yourself and you dare judge devs for using AWS. fuck off.
I agree with the sentiment, it sucks, if my platform was removed from AWS I probably would keep it that way because I don't have the money to afford the hardware nor am I somewhere that's readily available and that's what is really sad it would suck that just because Amazon doesn't like you or you don't have the influence to fight it you and your userbase can go fuck off. Very bad precedent, it is discouraging.68 -
I haven't ranted for today, but I figured that I'd post a summary.
A public diary of sorts.. devRant is amazing, it even allows me to post the stuff that I'd otherwise put on a piece of paper and probably discard over time. And with keyboard support at that <3
Today has been a productive day for me. Laptop got restored with a "pacman -Syu" over a Bluetooth mobile data tethering from my phone, said phone got upgraded to an unofficial Android 9 (Pie) thanks to a comment from @undef, etc.
I've also made myself a reliable USB extension cord to be able to extend the 20-30cm USB-A male to USB-C male cord that Huawei delivered with my Nexus 6P. The USB-C to USB-C cord that allows for fast charging is unreliable.. ordered some USB-C plugs for that, in order to make some high power wire with that when they arrive.
So that plug I've made.. USB-A male to USB-A female, in which my short USB-C to USB-A wire can plug in. It's a 1M wire, with 18AWG wire for its power lines and 28AWG wires for its data lines. The 18AWG power lines can carry up to 10A of current, while the 28AWG lines can carry up to 1A. All wires were made into 1M pieces. These resulted in a very low impedance path for all of them, my multimeter measured no more than 200 milliohms across them, though I'll have to verify and finetune that on my oscilloscope with 4-wire measurement.
So the wire was good. Easy too, I just had to look up the pinout and replicate that on the male part.
That's where the rant part comes in.. in fact I've got quite uncomfortable with sentences that don't include at least one swear word at this point. All hail to devRant for allowing me to put them out there without guilt.. it changed my very mind <3
Microshaft WanBLowS.
I've tried to plug my DIY extension cord into it, and plugged my phone and some USB stick into it of which I've completely forgot the filesystem. Windows certainly doesn't support it.. turns out that it was LUKS. More about that later.
Windows returned that it didn't support either of them, due to "malfunctioning at the USB device". So I went ahead and plugged in my phone directly.. works without a problem. Then I went ahead and troubleshooted the wire I've just made with a multimeter, to check for shorts.. none at all.
At that point I suspected that WanBLowS was the issue, so I booted up my (at the time) problematic Arch laptop and did the exact same thing there, testing that USB stick and my phone there by plugging it through the extension wire. Shit just worked like that. The USB stick was a LUKS medium and apparently a clone of my SanDisk rootfs that I'm storing my Arch Linux on my laptop at at the time.. an unfinished migration project (SanDisk is unstable, my other DM sticks are quite stable). The USB stick consumed about 20mA so no big deal for any USB controller. The phone consumed about 500mA (which is standard USB 2.0 so no surprise) and worked fine as well.. although the HP laptop dropped the voltage to ~4.8V like that, unlike 5.1V which is nominal for USB. Still worked without a problem.
So clearly Windows is the problem here, and this provides me one more reason to hate that piece of shit OS. Windows lovers may say that it's an issue with my particular hardware, which maybe it is. I've done the Windows plugging solely through a USB 3.0 hub, which was plugged into a USB 3.0 port on the host. Now USB 3.0 is supposed to be able to carry up to 1A rather than 500mA, so I expect all the components in there to be beefier. I've also tested the hub as part of a review, and it can carry about 1A no problem, although it seems like its supply lines aren't shorted to VCC on the host, like a sensible hub would. Instead I suspect that it's going through the hub's controller.
Regardless, this is clearly a bad design. One of the USB data lines is biased to ~3.3V if memory serves me right, while the other is biased to 300mV. The latter could impose a problem.. but again, the current path was of a very low impedance of 200milliohms at most. Meanwhile the direct connection that omits the ~200ohm extension wire worked just fine. Even 300mV wouldn't degrade significantly over such a resistance. So this is most likely a Windows problem.
That aside, the extension cord works fine in Linux. So I've used that as a charging connection while upgrading my Arch laptop (which as you may know has internet issues at the time) over Bluetooth, through a shared BNEP connection (Bluetooth tethering) from my phone. Mobile data since I didn't set up my WiFi in this new Pie ROM yet. Worked fine, fixed my WiFi. Currently it's back in my network as my fully-fledged development host. So that way I'll be able to work again on @Floydian's LinkHub repository. My laptop's the only one who currently holds the private key for signing commits for git$(rm -rf ~/*)@nixmagic.com, hence why my development has been impeded. My tablet doesn't have them. Guess I'll commit somewhere tomorrow.
(looks like my rant is too long, continue in comments)3 -
I just signed up to get this off my chest.
Dear Windows, you god damn moronic, ugly, unuseable abomination of an excuse for an OS. I wonder how we could end up here in this situation. You suck, in every way imaginable. I didnt choose Linux or Mac, you made me do it.
I know no other OS that can screw you up this bad when setting up. My friend is an experienced windows user and the last install took him 2 days. I just spend the last day trying to get this uncompatible sucker installed. I manage to set up an hackintosh quicker than I was able to install Windows the last three times I checked, you scumbag.
Your error messages suck ass, there is nothing I cant figure out given enough time, except your useless hints and pathetic attemps to get anything done on your own.
And you are fucking slow. Just why, do you keep installing stuff I didnt ask you to. Now I got this ugly ass Bing-Toolbar because I missed a damn checkbox in an .exe, which could have also been an exploit, you never know.
You are cluttered with useless stuff. I dont care about you lame ass app store, idc about your cortana annoying spy assistant and I certainly dont care about your forced updates.
Just sit back and feel your PC getting slower every day by background processes. Watch your productivity decline while dealing with their brain dead privilege and file system.
You ugly malformed mutation of software. When I look at your UI I feel disgust while wondering how you can fail with the most basic principles of UX.
How pathetic, badly supported, bug ridden and dangerously unsecure can an OS be you ask while trying to navigate through the settings, a pile of legacy software debt this garbage pile was build on. And your shell... what a sick joke.
I hate you Windows. For screwing other OS with your asshole boot manager, hardware driver requirements and making people send me .zip and .docx. You should be embarrassed to charge money for this unfunctional junk, but you do, a lot.
I really try to see the positive here. You got all the software, but thats not on you, thats because all those poor suckers are trapped with you and the effort to change is too big.
This OS is the most disappointing thing technology could come up with today. I would rather set myself on fire than work with this pain in the ass software professionally. I mean if you are a serious developer at some point you have to admit that you just cant develop on windows. You will get fucked 5 times as often as any Mac or Linux user. Fuck you, Windows.
Hey Microsoft, thanks for Typescript and VSCode and all the other good things you have done. But burn in hell for what you have done to all of us with this piece of shit OS.10 -
I finally fucking made it!
Or well, I had a thorough kick in my behind and things kinda fell into place in the end :-D
I dropped out of my non-tech education way too late and almost a decade ago. While I was busy nagging myself about shit, a friend of mine got me an interview for a tech support position and I nailed it, I've been messing with computers since '95 so it comes easy.
For a while I just went with it, started feeling better about myself, moved up from part time to semi to full time, started getting responsibilities. During my time I have had responsibility for every piece of hardware or software we had to deal with. I brushed up documentation, streamlined processes, handled big projects and then passed it on to 'juniors' - people pass through support departments fast I guess.
Anyway, I picked up rexx, PowerShell and brushed up on bash and windows shell scripting so when it felt like there wasn't much left I wanted to optimize that I could easily do with scripting I asked my boss for a programming course and free hands to use it to optimize workflows.
So after talking to programmer friends, you guys and doing some research I settled on C# for it's broad application spectrum and ease of entry.
Some years have passed since. A colleague and I built an application to act as portal for optimizations and went on to automate AD management, varius ssh/ftp jobs and backend jobs with high manual failure rate, hell, towards the end I turned in a hobby project that earned myself in 10 times in saved hours across the organization. I felt pretty good about my skills and decided I'd start looking for something with some more challenge.
A year passed with not much action, in part because I got comfy and didn't send out many applications. Then budget cuts happened half a year ago and our Branch's IT got cut bad - myself included.
I got an outplacement thing with some consultant firm as part of the goodbye package and that was just hold - got control of my CV, hit LinkedIn and got absolutely swarmed by recruiters and companies looking for developers!
So here I am today, working on an AspX webapp with C# backend, living the hell of a codebase left behind by someone with no wish to document or follow any kind of coding standards and you know what? I absolutely fucking love it!
So if you're out there and in doubt, do some competence mapping, find a nice CV template, update your LinkedIn - lots of sources for that available and go search, the truth is out there! -
Hey guys.
Arduino + Bluetooth + L293D + car Chacis and 4 DC motors.
Finaly finished my second bot/Drone.
Actually finished it yesterday but had lots of problems with hardware bugs (learned so fucking much in a day).
Tought I fucked two unos with bad soldering... No they are fine, just won't turn on in the circuit that was already working (was fine running the code).
Redone everything from scratch with a arduino uno, it's perfect now.
Funniest part is how I got my hands on a 50€ car kit for almost free... So some Chinese store sended this kit instead of some cheap stuff. Saved another arduino with the chip rack (that one that you can trade the atmega chip), I'll save it to program single chips. Plus a h bridge and lot lot more cool stuff.
Used only the Chacis.
Next: esp8266 and camera... And maby a gun? Would be cool32 -
AAARGH ELECTRON IS SO FUCKING...decently pleasant to use?
So I've been working on a FPGA based synthesizer on a Xilinx Arty A7 board (that little Artix 35T chip is surprisingly capable), and since I hate typing commands into a serial stream for anything even decently complex just like any sane person should, I needed something to build a UI for controlling it and other synth projects while I make the Eurorack compatible enclosure and knobs and stuff. I chose Electron because they said it was simple and easy to make cool looking stuff, fast.
And they were right. In like two hours, with Electron and p5.js, starting from zero since I don't know jack about frontend, I had a pretty nice UI driving the hardware synth and effects modules. Not bad. I should use this more often.11 -
If you ask me, you're a bad developer if you don't know hardware. You have to know how it all works and fits together to write code for it.18

This is the craziest shit... MY FUCKING SERVER JUST SET ON FIRE!!!
Like seriously its hot news (can't resist the puns), it's actually really bad news and I'm just in shock (it's not everyday you find out your running the hottest stack in the country :-P)... I thought it slow as fuck this morning but the office internet was also on the fritz so I carried on with my life until EVERYTHING went down (completely down - poof gone) and within 2 minutes I had a technician from the data centre telling me that something to do with fans had failed and they caught fire, melted and have become one with the hardware. WTF? The last time I went to the data centre it was so cold I pissed sitting down for 2 days because my dick vanished.
I'm just so fucking torn right now because initially I was absolutely fucking ecstatic - 1 week ago after a year of doomsday bitching about having a single point of failure and me not being a sysadmin only to have them look at me like I'm some kind of techie flat earther I finally got approval to spend around 5x more per month and migrate all our software to containerized micro services.
I'll admit this is a bit worse than I expected but thanks to last week at least I have recent off site images of the drives - because big surprise I have to set this monolithic beast back up (No small feat - its gonna be a long night) on a fresh VPS, I also have to do it on premises or the data will only finish uploading sometime next week.
Pro Tip: If your also pleading for more resources/better production environment only to be stone walled the second you mention there's a cost attached be like me - I gave them an ultimatum, either I deploy the software on a stack that's manageable or they man the fuck up and pay a sys admin (This idea got them really amped up until they checked how much decent sys admins cost).
Now I have very flexible pockets because even if I go rambo the max server costs would only be 15-20% of a sys admins paycheck even though that is 13 x more than our current costs. -
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 -
Sat down with the Project Management team today to discuss a signage installation. This is how the conversation went...
Me: Right, so we need to get the hardware on-site asap so we can get this configured before it goes over to the production guys to have the facisa installed.
Them: That's fine we have plenty of time. Stop rushing things.
Me: Okay, so do we have the story board in place ready for development?
Them: Nope. Hasn't been done by the designer yet because he is in a bad mood.
Me: Okay so when does the client want this?
Them: 3 Weeks' time
Me: But it is atleast a week of dev time?
Them: Sure. But you can work late if needed...right?
This is a typical conversation between them and me. I'm the sole developer here. So done with today.12 -
I have been working for my current employer about 3 years now. When I first got to work I was asked by another employee to work on an editor for certain types of files. We will call this employee Ed. Because his name is Ed.
Ed is a verifiable genius, and a genuinely great guy to work with. He is amazing with hardware and math. Ed has a need, or shall I say fetish. He wants an editor for some our proprietary files called "Settings files". They are just xml. Nothing special.
However, I have always had other priorities. We actually had a tense moment when I had to tell Ed my boss doesn't want me to work on the editor. I had started looking into working on the editor when my boss said stop working on this file. So since then it had become a running joke between Ed and myself. Well, I think it is funny, Ed smiles, but I know he wants this editor bad. Our boss even suggested at one time that Ed write this editor. He looked into it, but "other priorities" trumped this effort.
Okay, so now it has been 3 years and we still don't have this editor. Then I had an epiphany. Since Ed wants this editor I found an idea for the name of this program. "Settings Editor" is just too mundane. I now think it should be called: "Mr. Edit". I also found that the library we use for most of our development has text to speech built in. So when the program starts I can have it say: "Hello, I am Mr. Edit, the talking Settings Editor". I have never wanted to write this program so badly before. Muahahahahaha!5 -
After 9 weeks of waiting for my much delayed dell xps 15 i opened the box and it's fucking azerty ... While i clearly, CLEARY requested qwerty. I mentioned it 4 fucking times for the love of god make sure the keyboard is fucking QWERTY .. THEY GAVE ME AZERTY .. on top of that shittrain they also forgot to include my integrated fingerprint reader which i paid extra for.. man what a fucking shit company .. they might make half decent hardware but they piss all costumers of with their insanely bad braindead costumer service and sales team.
9 weeks of waiting , receiving the wrong configuration, probably again 5 more weeks of waiting.. man im starting to hate this shit company.7 -

Never buy crappy, consumer-grade SSDs for use in production servers/RAIDs. This might sound obvious but at the company I used to work for, through a series of bad decisions by management and cheapness, we ended up with the cheapest consumer SSDs you can imagine powering all of our storage.
This turned into a nightmare spanning years of failed hard drives and a continues cycle of ridiculousness. Drive failed after a few days, gets taken out, sent back to manufacturer and then replaced with another equally crappy drive destined to fail within days/weeks.
Our ops people were going to the data center multiple times per week to replace failed drives. Lesson I learned: cheaping out on system-critical hardware and software can have long standing consequences and in the end usually doesn't end up actually saving money when you account for time employees have to spend dealing with issues that result from it. -
Sometimes I just don't know what to say anymore
I'm working on my engine and I really wanna push high triangle counts. I'm doing a pretty cool technique called visibility rendering and it's great because it kind of balances out some known causes of bad performance on GPUs (namely that pixels are always rasterized in quads, which is especially bad for small triangles)
So then I come across this post https://tellusim.com/compute-raster... which shows some fantastic results and just for the fun of it I implement it. Like not optimized or anything just a quick and dirty toy demo to see what sort of performance I can get
... I just don't know what to say. Using actual hardware accelerated rasterization, which GPUs are literally designed to be good at, I render about 37 million triangles in 3.6 ms. Eh, fine but not great. Then I implement this guys unoptimized(!) software rasterizer and I render the same scene in 0.5 ms?!
IT'S LITERALLY A COMPUTE SHADER. I rasterize the triangles manually IN SOFTWARE and write them out with 64-bit atomic image stores. HOW IS THIS FASTER THAN ACTUAL HARDWARE!???
AND BY LIKE A ORDER OF MAGNITUDE AT THAT???
Like I even tried doing some optimizations like backface cone culling on the meshlets, but doing that makes it slower. HOW. Im rendering 37 million triangles without ANY fancy tricks. No hi-z depth culling which a GPU would normally do. No backface culling which a GPU with normally do. Not even damn clipping of triangles. I render ALL of them ALL the time. At 0.5 ms7 -
So I enventually spent 2 years working for that company with a strong b2b market. Everything from the checkouts in their 6 b2c stores to the softwares used by the 30-people sales team was dependant on the main ERP shit home-built with this monstruosity we call Windev here in France. If you don't know it just google and have some laugh : this is a proprieteray FRENCH language. Not french like made by french people, well that too, but mostly french like the fucking language is un fucking french ! Instructions are on french, everything. Hey that's my natural language okay, but for code, really ?
The php website was using the ERP database too, even all the software/hardware of the massive logistic installation they had (like a tiny Amazon depot), and of course the emails of all employees. Everything was just handled by this unique shitty and so sloooooow fucking app. When there was to many clients on the website or even too many salespeople connected to the ERP at the same time, every-fuckin-piece of the company was slowing down, and even worse facing critical bugs. So they installed a monitor in the corner of a desk constantly showing the live report page of Google analytics and they started panic attacks everytime it was counting more than 30 sessions on the website. That was at the time fun and sad to observe.
The whole shit was created 12 years ago and is since maintened locally by one unique old-fashion-microsoft dev who also have to maintain all the hardware of all the fucking 150+ people business. You know, when the keyboard of anyone is "broken" cause it's unplugged... That's his job too. The poor guy was totally overstressed on a daily basis and his tech knowledge just saddly losts themeselves somewhere in the way. He was my n+1 in a tech team of 3 people : him, a young and inexperimented so-called "php developer" who was in charge of the website (btw full of security holes I discovered and dealed with when I first arrive at the job), and myself.
The database was a hell of 100+ tables of business and marketing data with a ton of specific logic added on-the-go during years. No consistent data model or naming. No utf8. Fucked up relations that ends with queries long enough to fill books. And that's not all, all the customers passwords was just stored there uncrypted. Several very big companies and administrations were some of these clients. I was insisting on the passwords point litterally all the time, that was an easy security fix and a good start... But no, in two years of discussions on the subject I never achieved to have them focusing on other considerations than "our customers like that we can remind them their password by a simple phone call if they lost it". What. The. Fuck. WHATTHEFUCK!
Eventually I ran myself out of this nightmare. I had a few bad jobs already, and worked on shitty software already. But that one really blows my mind (and motivation for a time too). Happy it's over.1 -
Me: Hmm... My Android phone has been acting strange lately, cell signal keeps dropping... Maybe I picked up a virus... let's flash the latest update.
Phone: Updating Done
Me: Hm... signal is still bad... maybe it's hardware... *Angry*
Phone: By the way you lost root
Me: @#$%$&&$%^#$!#$@$%$#%^ OK LETS SEE, SUPERSU, REINSTALL THE BINARIES... YES!!!
Phone: Reinstalling... Restarting...
......................................................
......................................................
Me: it's not loading.... why? NO! I bricked it..... NO NO NO NO.....
*1 hour of flailing...*
Hey Recovery still works! OK, let's try to reflashing the OS
Phone: Flashing... Restarting...
Me: Please, please... let this work.... it's not starting............. wait. IT LOADED!!!! WOOT!!!! AWESOME...
Phone: still no root...
Me: Eh...
And there went my most of my evening which I was supposed to spend preparing for an interview tomorrow....6 -
Going out on a limb here... have any of you done any bare-metal phone programming (not counting compiling like AOSP and such, like totally arbitrary code at boot-time, or bootloader coding, ideally) or know someone that has? A friend got bit by a bad iOS app on a jailbroken iPhone 8 (checkra1n, so no unsigned firms or anything) that has installed a bad iCloud lock on the device, and I need checkm8 shellcode to zero most of if not all of the NAND to get rid of it (since an iTunes restore preserves that data) and I can't figure out jack shit about how any of this works, since ARM isn't strict on what goes where in the address space or how to access hardware.11

TIL if you know the password for a WIFi SSID, you can replicate it with your hardware. All devices that have credentials for that SSID will connect to yours if your signal is stronger. The encryption just needs to be the same (wpa2/wep) The underlying UUID doesn’t matter.
Not bad for a quick and dirty man-in-the-middle attack. The WiFi spec needs a bit more work.
TLS all the things!4 -
The good: use the hardware watchdog in your application control flow.
The bad: don't use a watchdog.
The ugly: trigger the watchdog from a fucking timer interrupt.3 -
Decided to go back to windows for a bit after not using it for about 6 months (on physical hardware) and literally forgot there was a start menu, minimise button, taskbar and that the window controls are on the right...
I have done the impossible and almost forgotten how to use windows, not sure if this is a good or bad sign9 -
Inspired by @NoMad. My philosophy is that technology is a means to and ends. We’re a tool oriented species. As it relates to software and hardware, they should be your means to achieve your ends without you needing to think. Think of riding a bicycle or driving a car. You aren’t particularly conscious of them - you just adjust input based on heuristics and reflex - while your doing the activity.
For a long time Software has been horrendously bad at this. There is almost always some setup involved; you need to front-load a plan to get to your ends. Funny enough we’re in the good days now. In the early days of GUI you did have to switch modes to achieve different things until input peripherals got better.
I’ve been using windows from 95 and to this day, though it’s gotten better it’s not trivial to setup an all in one printer and scan a document - just yesterday I had to walk my mother through it and she’s somewhat proficient. Also when things break it’s usually nightmare to fix, which is why fresh installing it periodically is s meme to this day. MS still goes to great lengths with their UI so that most people can still get most of their daily stuff done without a manual.
I started Linux in University when I was offered an intro course on the shell. I’ve been using it professionally ever since. While it’s good at making you feel powerful, it requires intricate knowledge to achieve most things. Things almost never go smoothly no matter how much practice you have, especially if you need to compile tools from source. It also has very little in the ways of safe guards to prevent you from hurting yourself. Sure you might be able to fix it if you press harder but it’s less stress to just fresh install. There is also nothing, NOTHING more frustrating than following documentation to the T and it just doesn’t work! It is my day job to help companies with exactly this. Can’t really give an honest impression of the GUI ux as the distros have varying schools of thoughts with their desktop environments. Even The popular one Ubuntu did weird things for a while. In my humble opinion, *nix is better at powering the internet than being a home computer your grandma can use.
Now after being in the thick of things, priorities change and you really just want to get things done. In 2015 I made the choice to go Mac. It has been one of my more interesting experiences. Honestly, I wish more distros would adopt its philosophy. Elementary only adopted the dock. It’s just so intuitive. How do you install an application? You tap the installer, a box will pop up then you drag the icon to the application folder (in the same box) boom you are done. No setup wizards. How to uninstall? Drag icon from app folder to trash can. Boom done. How to open your app? Tap launch pad and you see all your apps alphabetically just click the one you want. You can keep your frequent ones on the dock. Settings is just another app in launchpad and everything is well labeled. You can even use your printers scanner without digging through menus. You might have issues with finder if your used to windows though and the approach to maximizing and minimizing windows will also get you for a while.
When my Galaxy 4 died I gave iPhone a chance with the SE. I can tell you that for most use cases, there is no discernible difference between iOS and modern android outside of a few fringe features. What struck me though was the power of an ecosystem. My Mac and iPhone just work well together. If they are on the same network they just sync in the background - you need to opt in. My internet went down, my iMac saw that my iPhone had 4g and gave me the option to connect. One click your up. Similar process with s droid would be multi step. You have airdrop which just allows you to send files to another Apple device near you with a tap without you even caring what mechanism it’s using. After google bricked my onHub router I opted to get Apples airport series. They are mostly interchangeable and your Mac and iOS device have a native way to configure it without you needing to mess with connecting to it yourself and blah. Setup WiFi on one device, all your other Apple devices have it. Lots of other cool stuff happen as you add more Apple devices. My wife now as a MacBook, an IPad s d the IPhone 8. She’s been windows android her life but the transition has been sublime. With family sharing any software purchase works for all of us, and not just apples stuff like iCloud and music, everything.
Hate Apple all you want but they get the core tenet that technology should just work without you thinking. That’s why they are the most valued company in the world14 -
New programmer who just pick up Python be like , C is shot , is bad , python better blablabla....
Why anyone hate C so much? I personally use C for Embedded Programming, for hardware or is better compare to using python for my case.
I love python , but I love C more. Because without C the rest don't exist. Right?
So stop hating on C. Because you might use it someday.17 -
How ignorant we all are about the world. It's not necessarily a bad thing, just a fact. After a four year degree I've learnt so much, how a computer works from the physical phenomena on the hardware level to the inner workings of an OS to the highest level abstractions of modern web development, a wide array of programming languages covering several different paradigms, mathematics from calculus to statistics to algebra, how to work with databases, how to administrate a server, how to build a website, and much more.
And that's just in a degree. I have knowledge in one domain and I wouldn't even call myself an expert in it. Medicine, physics, biology, the hundreds of branches of engineering from civil to nautical to aerospace to automobile, to geology to meteorology to astronomy, to the practical application of this knowledge in hundreds of trades. There's so much more to know in so much depth and only recently have I realized how little we all know on an individual level.
Finding this out has been a mixed bag, on the one hand it's made me value what I know and what others can teach me a hell of a lot more, on the other, knowing that people haven't realized this and adamantly discuss and impose from a position of ignorance isn't very nice.
tl;dr I know that I know nothing3 -
Fuck you AMD for being too lazy to implement VK_EXT_fragment_shader_interlock even though your hardware supports it [1]
It's literally *the* best way to implement any sort of order independent transparency ( https://web.archive.org/web/... )
But noo, not enough people are using it so too bad. Now you just have to render transparent objects all fucked up and bad looking on AMD hardware because "we don't feel like it"

I've been a Macbook user for over a decade, after the initial disappointment of the 2016 MacBook Pro release I decided to move to a PC, against my better judgement I decided to buy a new Dell XPS 15, after reading all the reviews praising it's build quality and performance + it seems to have good hardware for Linux compatibility.
Soo much regret, I couldn't be more disappointed, it's such a piece of shit, I admit I probably got a bad egg, but dealing with Dell support is like pulling hairs from my testicle sack. If I have to pay an extra $500-$1000 on my next laptop for an "Apple Tax" to get a product that has been through proper quality control and has awsome customer service so be it, last time I try something new.
BTW I'm not a PC hater, I just wish more companies made high quality products.10 -
One of our customers wants our mobile app to log out the user after 15 minutes of inactivity because of SeCuRiTy…
Why? The phones protect the apps with their hardware encryption from any malicious access.
And we are not dealing with super sensitive data here like some banking app or so.
Why do some people want to have bad UX for no reason?12 -
So recently I installed Windows 7 on my thiccpad to get Hyperdimension Neptunia to run (yes 50GB wasted just to run a game)... And boy did I love the experience.
ThinkPads are business hardware, remember that. And it's been booting Debian rock solid since.. pretty much forever. There are no hardware issues here. Just saying.
With that out of the way I flashed Windows 7 Ultimate on a USB stick and attempted to boot it... Oh yay, first hurdle to overcome. It can't boot in UEFI mode. Move on Debian, you too shall boot in BIOS mode now! But okay, whatever right. So I set it to BIOS mode and shuffled Debian's partitions around a bit to be left with 3 partitions where Windows could stick in one more.
Installed, it asks for activation. Now my ThinkPad comes with a Windows 7 Pro license key, so fuck it let's just use that and Windows will be able to disable the features that are only available for Ultimate users, right? How convenient would that be, to have one ISO for all the half a dozen editions that each Windows release has? And have the system just disable (or since we're in the installer anyway, not install them in the first place) features depending on what key you used? Haha no, this is Microsoft! Developers developers developers DEVELOPERS!!! Oh and Zune, if anyone remembers that clusterfuck. Crackhead Microsoft.
But okay whatever, no activation then and I'll just fetch Windows Loader from my webserver afterwards to keygen my way through. Too bad you didn't accept that key Microsoft! Wouldn't that have been nice.
So finally booted into the installed system now, and behold finally we find something nice! Apparently Windows 7 Enterprise and Ultimate offer a native NFS driver. That's awesome! That way I don't have to adjust my file server at all. Just some fuckery with registry keys to get the UID and GID correct, but I'll forgive it for that. It's not exactly "native" to Windows after all. The fact that it even has a built-in driver for it is something I found pretty neat already.
Fast-forward a few hours and it's time to Re Boot.. drivers from Lenovo that required reboots and whatnot. Fire the system back up, and low and behold the network drive doesn't mount anymore. I've read that this is apparently due to Windows (not always but often) mounting the network drive before the network comes up. Absolutely brilliant! Move out shitstaind, have you seen this beauty of an init Mr. Poet?
But fuck it we can mount that manually after every single boot.. you know, convenient like that. C O P E.
With it now manually mounted, let's watch a movie! I've recently seen Pyro's review on The Platform and I absolutely loved it. The movie itself is quite good too. Open the directory on my file server and.. oh. Windows.. you just put db.thumb on it and db.thumb:encryptable. I shit you not, with the colon and everything. I thought that file names couldn't contain colons Windows! I thought that was illegal in NTFS. Why you doing this in NFS mate? And "encryptable", am I already infected with ransomware??? If it wasn't for the fact that that could also be disabled with something as easy as a registry key, I would've thought I contracted ransomware!
Oh and sound to go with that video, let's pair up some Bluetooth headphones with that Bluetooth driver I installed earlier! Except.. haha nope. Apparently you don't get that either.
Right so let's just navigate the system in its Aero glory... Gonna need to flick the mouse for that. Except it's excruciatingly slow, even the fastest speed is slower than what I'm used to on Linux.. and it's jerky as hell (Linux doesn't have any of that at higher speed). But hey it can compensate for that! Except that slows down the mouse even more. And occasionally the mouse driver gets fucked up too. Wanna scroll on Telegram messages in a chat where you're admin? Well fuck you mate, let me select all these messages for you and auto scroll at supersonic speeds! And God forbid that you press delete with that admin access of yours. Oh maybe I'll do it for you, helpful OS I am!
And the most saddening part of it all? I'd argue that Windows 7 is the best operating system that Microsoft ever released. Yeah. That's the best they could come up with. But at least it plays le games!10 -
We are so fucked up at our company:
While the support for our client hardware is running out, our operation departement has just found out that Windows 7 is no longer supported on new HW. Well, that for itself is not bad, but we have a really old tool for reporting our daily work. And because that mo*fu*ing piece of customized software still runs in 16bit mode, it will not run on Win 10 anymore.
Alternative solutions are too expensive, so I see that we will have to port that crap somehow from 1997 to 2017 ourself 😲 Replacing is not an option because there are a ton of Excel sheets connected to the database, even the company balance is made with that data (and also in Excel). At least it is our CEO which has built that crap. So he has to pay for his twenty year old sins!4 -
At work we have to split a potentially large ID into 2 10-digit long parts that will be passed to an outside system that will later return them with some more data to us.
A colleague had implemented it using regular expression, it passed code review, everything was ok, until he noticed a potential problem. For some cases, because the outside system stores them as int and therefore will remove any leading zeros, there will be no way to reconstruct the number.
So we brainstorm and I propose ether a modified regex, or to just use math like part1 = id % 10^10 and part2 = floor(id % 10^10) and then we can reconstruct it simply by: part2 * 10000000000 + part1
Colleague: - Well, the regex will be faster, there won't be any calculations
Me: - :| I disagree but ok..
We do some more brainstorming and testing and find a case where the proposed new regex fails as well
So I bring up my previous proposal, I explain what exactly it does.
Colleague: - I don't like the math, it has calculations, which won't be needed before we reach the 11th digit
Have I missed some major development in computer hardware? When did they become bad/slow at doing math? :|8 -
HEYYY!!
Glad to see ya all, how have ya been?
Gosh, it has been forever since the last time! I feel like I forgot about this platform too much, it feels good to have a place full of wonderful people to speak to, and you don't see those everywhere. I'm sorry I haven't been here much, it was mostly due to me not being able to practice programming much and thus falling back on tech stuff.
BUT - that period is now over. Maybe.
I'm gonna be more active on here, in the past recent years I've seen how bad most social medias turned out to be, with a few very special exceptions. I think devRant deserves more activity, so for better or for worse (hopefully better), I'm back!
I think my biggest problem right now is the need for a better PC, one Italians would call "a PC with the controcazzi", lol. A good one, is what I'm sayin. But would ya look at that, thr moment I start searching up for one, a friggin pandemic takes place and prices skyrocket! Ain't that fun. XD
I would probably have found an awesome PC build by now if I knew jack shit about hardware, but unfortunately I was always more into software than hardware. ^^"
So if anybody has any idea, I mean, I'm open to suggestions~ they'd be very appreciated, and thanks in advance. <3
But enough about that - how are you holding up? I hope you're doing good.
Misadventures and bad stuff happen, but I promise you we're all gonna get out of it soon. In the meantime, always remember to drink water, eat properly, keep yourself sanitized, exercise, and do things you love doing. That's what life is about. I'm looking forward to hearing from y'all, once again. 💙
Keep fighting the good fight, and kick ass! And chew gum, too.rant tag you're it still dunno in what order tags are in lol i'm back baby! you're lookin cute today~2 -
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 -
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 -
Today, I have installed/uninstalled a combination of [windows 7, arch linux, dual-boot] a total of 9 times...
I wouldn't be surprised if my 120G SSD fails next week
It all started when I had to whip up a GUI-wrapped youtube-dl based program for a windows machine.
Thinking a handy GUI python library will get it done in no time, I started right away with the Kivy quick-start page in front of me.
Everything seemed to be going fine, until I decided it would be "wise" to first check if I can run Kivy on said windows machine.
Here I spent what felt like a day (5 hours) trying to install core pip modules for kivy.. only before realizing my innocent cygwin64 setup was the reason everything was failing, and that sys.platform was NOT set to "win32" (a requirement later discovered when unpacking .whl files)
"Okay.. you know what? Fuck........ This."
In a haze of frustration, I decided it was my fault for ever deciding to do Python on windows, and that "none of this would've happened if I were installing pip modules on a Linux terminal"...
I then had the "brilliant" idea of "Why don't I just use Linux, and make windows a virtual machine within, for testing."
And so I spent the next hour getting everything set up correctly for me get back to programming.... And so I did.
But uh... you're doing GUI stuff, right? -> Yeah...
And you uh.. Kivy uses OpenGL on windows, doesn't it? -> Yeah..?
OpenGL... 2.
-> Fuck.
That's when I realized my "brilliant" idea, was actually a really bad prank. Turns out.. I needed a native windows environment with up-to-date non-virtual graphics drivers that supported at least OpenGL2 for Kivy GUI programs!
Something I already had from square 1.
And at this point, it hurts to even sigh knowing I wasted hours just... making... poor decisions, my very first one being cygwin64 as a substitution for windows cmd.
But persistent as any programmer should be in order to succeed, I dragged my sorry ass back to the computer to reinstall windows on the actual hardware... again.
While the windows installer was busy jacking off all over my precious gigabytes (why does it need that much spaaace for a base install??? fuck.). I had "yet another brilliant idea" YABI™
Why not just do a dual-boot? That way, you have the best of both worlds, you do python stuff in Linux, and when it's time to build and test on the target OS, you have a native windows environment!
This synthetic harmony sounded amazing to the desperate, exhausted, shell of a man that I had become after such a back-breaking experience with cygwin
Now that my windows platter with a side of linux was all set-up and ready-to-go, I once again booted up windows to test if Kivy even worked.
And... It did!
And just as I began raising my victory flags, I suddenly realized there was one more thing I had to do, something trivial, should take me "no time" to do, being in a native windows environment and all.................... -.- (sigh)
I had to make sure it compiles to a traditional exe...
Not a biggy, right? Just find one of those py2exe—sounding modules or something, and surprisingly enough, there was indeed a py2exe—sounding module, conveniently named... py2exe.
Not a second thought given, I thought surely this was a good enough way of doing it, just gonna look up the py2exe guide and...
-> 3 hours later + 1 extra coffee
What do you meeeeean "module not found"? Do I need to install more dependencies? Why doesn't it say so in the DAMN guide? Wait I don't? Why are you showing me that error message then????
-------------------------------
No. I'm not doing this.
I shut off my computer and took a long... long.. break.
Only to return sometime the next day and end up making no progress, beating my SSD with more OS installs (sometimes with no obvious reason to do so).
Wondering whether I should give up Kivy itself as it didn't seem compatible with py2exe.. I discovered pyInstaller, which seemed to be the way Kivy wants exe's to be made on windows..
Awesome! I should've looked up how Kivy developers make exe's instead of jumping straight into py2exe land, (I guess "py2exe" just sounded more effective to me then)
More hours pass, and you'd think I'd have eliminated all of my build environment problems by now... but oh, how wrong you'd be...
pyInstaller was failing, and half the solutions I found online were to download some windows update KB32946..whatever...
The other half telling me to downgrade from Python 3.8.1 to Python 3.8.0000.009 (exaggeration! But you get the point)
At the end of all that mess, I decided it wasn't worth some of my lifespan, and that maybe.. just maybe.. it would've been better to create WINDOWS GUI with the mother fuc*ing WINDOWS API.
Alright, step 1: Get Visual Studio..
Step 2: kys
Step 3: kys again.6 -
Damn. I am so blessed to have friends that i have. 90% of them don't even care if you live or die (60% of them would be the first to throw me in fire if that's benefitting to them) remaining 10% would be someone that slightly care, but will move on pretty quickly.
But the best thing about 1 of them is that he is bluntly honest , and willing to share his opinion.
Today we were just talking about stuff when i see this placement offer in my mail.
I have been recently feeling bad about my grades, my choice of persuing android , my choice of leaving out many other techs (like web dev or data sciences , whose jobs are coming in so much number in our college) and data structures, and my fear of not getting a good career start.
This guy is also like me in some aspects. He is also not doing any extreme level competitive programming. He doesn't even know android , web dev, ai/ml or other buzz words. He is just good in college subjects. But the fascinating thing about him,is that he is so calm about all of this! I am losing my nuts everyday my month of graduation , aug2020 is coming . And he is so peaceful about this??
So i tried discussing this issue with him .Let me share a few of his points. Note that we both are lower middle class family children in an awful, no opportunity college.
He : "You know i feel myself to be better than most of our classmates. When i see around , i don't see even 10 of them taking studies seriously. Everyone is here because of the opportunity. I... Love computer science. I never keep myself free at home. I like to learn about how stuff works, these networking, the router, i really like to learn."
"That's why i dont fear. Whatever the worst happens , i have a believe that i will get some job. Maybe later, maybe later than all of you , but i will. Its not a problem."
me: "but you are not doing anything bro! I am not doing anything ! So what if our college mates suck , Everyone out there is pulling their hairs out learning data structures, Blockchain, ai ml , hell of shit. But we are not! Why aren't you scared bro? Remember the goldman sach test you gave ? You were never able to solve beyond one question. How did you feel man? And didn't you thought maybe if i gave a year to that , i will be good enough? Don't you too want a good package bro? Everyone's getting placed at good numbers."
Him : "Again, its your thoughts that i am not doing things. I am happy learning at my own pace. Its my belief that i should be learning about networking and how hardware works first , then only its okay to learn about programming and ai ml stuff. I am not going to feel scared and start learning multiple things that i don't even wanna learn now."
"My point is whatever i am doing now, if its related to computers , then someday its gonna help me.
And i am learning ds too , very less at a time. Ds algo are things for people with extreme knowledge. We could have cleared goldman sachs if we had started learning all this stuff from 1st year, spend 2-3 years in it and then maybe we could have solved 2 -3 questions. I regret that a little, but no one told us that we should be doing this."
"And if i tell you my honest thoughts now, you ar better off without it. You are the only guy among us with good knowledge of android , you have been doing that for last 2 years. Maybe you will get better opportunity with android then with ds/algo."
"You know when i felt happy? When we gave our first placement test at sopra. I was thinking of going there all dumb. But at 11 am in night i casually told my brother about this ,and he said that its a good company. So i started studying a little and next day i sat for placement. And i could not believe myself when they told me that am selected. I was shit scared that night, when my dad came and said " you don't even want that job. Be happy that you passed it on your own". And then i slept peacefully that night and gave the most awesome interview the next day."
"Thus now i am confident that wherever my level of skills are, it is enough to get into a job . Maybe not the goldman sachs ,but i will do well enough with a smaller job too."
"Bro you don't even know... All my school mates are getting packages of 8LPA, 15LPA, 35LPA. You see they are getting that because they already won a race. They are all in better colleges and companies which come there, they will take them no matter what (because those companies want to associate themselves with their college tags). But if worst comes to worst, i won't be worried even if i have to go take 4lpa as job offer in sopra"
Damn you Aman Gupta. Love you from all my heart. Thanks for calming me down and making me realise that its okay to be average3 -
I need help.
I love software and hardware development but over a period of 4 years now i have lost motivation. I hardly finish anything i have started and if i finish, it's never rewarding.
I also feel like i live a very boring life. Staring at the screen all day and doing very little.
What do you guys do for fun? What activities or books do you read to keep yourselves busy or entertained?
I have been having this desire for someone to love but something makes me think that it's just a reaction to a soul that has lost purpose and only feels like loving someone will be a source of happiness. Luckily, nobody has been available for the mess i have been.
I really admire busy people. People who are passionately working on something they have chosen to do and still have fun.
I think talking to someone about how bad i feel about myself will help a little but what i really need is help on how to restore the motivation i had 4 years ago.
Can someone give me a fun project i can work on? Not for making money but something i will do, learn and feel happy about it.
I will also appreciate if someone can recommend a good book that will help me learn. Get me motivated and also hide me from this reality.
Thank you.1 -
okay just had a mind blown moment.
there are never 'technical errors'
everything is human error.
because at some point, a human started/caused whatever went wrong.
whether it was the fact that a human didn't account for something or made bad code, or made bad hardware,
every tech issue is a human one.

1. Windows is unreliable and crappy.(I have had a lot of bad experience with windows.)
2. Mac is good but doesn't have a lot of things to tinker with.(Used mac, it runs on specific hardware only, for rich people who don't know how to use computers or for chad programmers )
3. Linux is the best. (The real programmer shit that has it all.)
What do you think?40 -
I'm opening a case against Lenovo due to their bad warranty support. It's been over a month and a half since I reported an issue with my ThinkPad and they still haven't fixed it. The laptop was bought in September, the case opened in October and in December I still have a faulty screen with which I can't no longer work because it was frying my eyes. Note that this machine has a Warranty Extension for 3 years Onsite next business day repair.
TL;DR if you own a ThinkPad, pray that it doesn't have any hardware issues. If you're thinking about buying one, DON'T!5 -
Acer vs MSI Laptops.
Five years ago I bought an acer aspire vn7-591 laptop in Redcoon. It was the expensive laptop I bought ever in those days. My experience at the beginning was really bad because the battery laptop crashed after few months and the screen had some vague/dead pixels, but the worst was the imminent bankruptcy of Redcoon. So I couldn't use the warranty. Anyway, It didn't bother so much I have been enjoying this laptop and still doing it. However, last year the screen put me on alert since it started to fail with vertical bars and color changes.
It was time to buy a new computer and due to the problems with some of the components, I've decided to buy a laptop from a company with a better reputation than Acer in aspects as the reliability of the components.
My choice was a Msi Prestige 15 because of the thunderbolts, since the rest of specs are 'more or less similar', although it has more updated hardware, it is lighter, battery holds up to 4-5 hours etc... But... It is really noisy compared to my Acer computer. 2 CPU fans are around 3000 rpm in idle state... Acer seems to be working without using the fans if you are doing intensive work. I google it as I thought it was a factory problem, but it seems to be not a malfunctioning... In fact I found other users complaining about the same and the community proposed to reduce the fan speed through software.
Right now I have both laptops working and since the new boy is in house, Acer is working flawlessly. I am preparing the Acer for my girlfriend as a gift, otherwise it is a pitty to shut it down and store it in a wardrobe.
So, this is my impression about ACER and MSI. I m still experiencing with the new laptop, but I find weird things like the fan speed or how hot it gets in idle despite it uses a new generation of intel i7 cpu with lower consumption... I should monitor the power consumption...8 -
The universe has taken a cactus.
It proceeded to gift the cactus with a toxin that greatly enhances the stimulus of pain.
After the universe watched it's miraculous creation it decided to shove it up so far my arse that my gag reflex turned on and I puked a lot of cactus.
Didn't sleep well, weekend hardware migration finish, today an old server got moved.
Some part, most likely the redundant PSU, had a short circuit - decided to take the switches out... Which are the only non redundant hardware...
There was only one critical system in the whole rack, that was one redundant firewall.
Guess what happened..... Naaaa?
*drum roll*
For whatever reason, the second firewall didn't kick in, so large part of internal network unreachable as VPN was on the firewall.
:thumbsup:
That's not cactus level yet.
Spontaneously a large part of the work at home crew decided to call, cause getting an email wasn't enough.
So while all the phones were ringing and we had the joyful fun to carefully take apart a whole rack to check for possible faulty wiring / electric burns / hardware damage and getting firewall up and running again...
Some dev decided to run a deployment (doable as one of the few working at the company at the moment -.-).
I work from home, but we had a conference phone call running the whole time so I could "deescalate" and keep others up-to-date. So me on headphone with conference call, regular phone for calls, while typing mails / sms for de-escalation.
Now we're reaching cactus level, cause being tortured by being annoyed out of hell by all telephone ringing, the beeping of UPS (uninterruptible power supplies), the screaming of admins from the server room and the roaring of air coolers…
Suddenly said dev must have stood in the midst of the chaos… and asked for help cause "the deployment broke, project XY is offline"...
I think it was the first time since years that I screamed at the top of my lungs.
Bad idea (health issues)… but oh boy was it a pleasure to hear my own voice echo through the conference speaker and creating an echoic sound effect.
It was definitely worth coughing out my loungs for the next hour and I think it was the best emotional outburst ever.
I feel a bit sorry for the dev, but only a tiny bit.
After the whole rack thing, the broken deployment fixing and the "my ears are bleeding and I think I will never be able to talk again" action...
We had to roll out several emergency deployments to fix CVEs (eg libexpat).
This day was a marvelous shit show.
I will now cry myself to sleep with some codein.1 -
Since day 0, I have been fond of computers. One of my first plush was called "DataDog" and looked like a CRT screen with dog ears around. According to my mum I was "addicted" to it.
At year 2, my dad was arranging some music on some software while I was watching him on his lap. Quick jump to the present: nowadays and since 10 years I run my own home studio with three guitars, two keyboards, one bass, three monitors, a microphone, an amp and a cabinet... coincidence? I think not!
Fast forward 5 years later (so I'm 6-7 years old), and I was playing with the legendary pinball game on Win95, as well as Flight Simulator. Then I was hogging mum's laptop to play settlers II (<3 that game), I eventually got my computer, and got into Quake III Arena being aged 10 (and had to tell my mum that game was safe for my age haha - I eventually removed the blood effects).
The Quake 3 Arena chapter is interesting: it got me into router configuration as I wanted to open a port through the router to host my own dedicated games with friends, it got me into DNS configuration (I was running a no-DNS client that allowed friends to join me through a DNS while having a dynamic IP) and eventually... to modifying .cfg files to tune my server as I wanted it. No programming here but a nice intro into :)
Then I hated the fact everybody would point their finger at me and say "geek" - I was only 13, fragile, sensitive, and I wanted everything but a bad image on me.
Meanwhile I continued on getting interested in hardware and configure my own computers, and investing myself into music production.
Then, university. "What do you want to study?" I thought of everything but IT, fleeing the image of a "geek". Turns out it was a waste of time, and at 21 yo I got into web development (well, just html and css), then learned a bit of PHP, finally got a specialized 2-year training and now here I am!
I was bound to be in IT either way since day 0, and funny fact, I've used every windows edition since Win95. -
Why is so Fitbit so bad at multiple time zones??
Guess what, people get on planes and travel.
Every time, my Fitbit gets so screwed up, including things like changing previous step counts, or duplicating an entire day of steps.
I understand MTZ is a tough problem, but this is just unacceptable. I'm not obsessed with my steps, but when your product is all about counting something, seems like you should be more careful to avoid double counting or not counting at all. Seriously, how much R&D have they invested in their hardware and apps, but it completely fails when you travel. Get it together!1 -
A picture of the powerful cloud behind retoor1b, the hardware such model deserves: https://devrant.molodetz.nl/2024112...
It's blazing fast atm though: https://llm.molodetz.nl. It's just the base model.
Remote uploading of pictures isn't that bad tbh, now it's easy to share multiple and high quality. It won't be down as much as the LLM. This service runs on the VPS itself. Uploading is bit slow, don't know why. Probably buffer size related why using async to write the file to the disk. Disk is SSD, that's not it. LLM's run on different servers.4 -
Time for a 00:30 rant that has no structure!
(There is a theme tho)
TI-BASIC optimization (framecount is from TI-84 Silver, with the higher Z80 clock):
"0→S": 3 frames
"DelVar S": 2 frames
```
0
Ans →S
```
1 frame???
(Variable "Ans" holds the last answer given to the normal calc functions. This makes it blazing fast to use [for some reason])
also refreshing the real TI-8x line's LCD at its actual, normal rate is bad and *SOMEHOW* ends in LCD overvolting (makes parts of the LCD blue instead of dark gray) after ~15 frames. The TI-8x line's normal OS thing refreshes the LCD at 30-45FPS depending on their clock speed, the LCD is native 80FPS. Just figured i should point this out. (Yes, TI, you do make hardware, it's just that sometimes you should make it when SANE)
why the fuck did they make a multitasking machine that runs on a Z80 at, like, 7/8 the original Gameboy's speed (the B/W DMG, the original. The CGB had DoubleSpeed mode.)1 -
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 -
Dude in my Calc 2 class just bitched about iPhones having "shitty software" referencing that bug from around ~6 years ago, when a specific iMessage text would reboot your phone. IMO, 99% of what Apple does well is software. UI is subjective, but final cut pro is unbelievable in terms of functionality for its price, their software is so well optimized that iPhones have been able to use comparably tiny batteries and still compete. They are consistent throughout their company with software design, while companies like Google are so stratified it took years before their material design had been implemented in all their services, there are still a few that aren't (not to mention the meme of Google killing off all their projects). I hate tablets, but the iPad pro has the best software/hardware implementation of any I've ever seen. Apple's interconnectivity between devices is unbelievable, whether it's Continuity features or the setup process just recognizing group devices around and pulling data to create consistent account info and saving you taps. Siri is shit, but apart from that their software isn't bad enough that you should complain about that instead of...
Their Macs are fucking pressure-cookers, and their fuckin marketing department is like a different company all-together, and their anti-fix-it-yourself policies are so user hostile that they're toe-to-toe with being as abusive to customers as Oracle.
TL;DR the biggest scam Apple has pulled off is not that the sheep still think Android and PC users are living in 2010, but they've convinced the sheep that they know what shitty software is. At that point they're too many levels deep and there is no red-pill strong enough for them.2 -
I used to be an iPhone user since iPhone 3, every year switching to the new model, always complaining about limitations and jailbreaking it with the concerns this brings up to the table, anyway, I also tried other cellphones like Samsung Galaxy XXX, worse shit ever, and those annoying Samsung apps you cannot uninstall, pfff, worst of the worst.
I started with pure Android phones some years ago, first with pixel 2, holly shit, software is amazing, I was amazed an happy with my phone, "infinite cloud storage for free" yes please!!!
The problem comes after 5 months of use, battery drains in less than 3 hours, even with the cellphone screen off and not using it, it was under warranty and got a new battery for free, well, no that bad. Suddenly the apps start blocking each other and takes a lot to open or switch between apps. I bought also the famous PIXEL BUDS, worst purchase ever, you never know if they are charging or still connected, no matter how hard do you try, it randomly connects, I tried all the possible solutions, didn't work, one random day, the buds went off, got new ones thanks to the warranty, now they are starting to fail again.
Bought the pixel 3, same exact shit as before, same errors, same shitty hardware, battery drains in hours, and I am a regular user, I do not have games or use it in an intensive way.
Conclusion:
- Google: Shitty hardware, great software, no limitations(I can send you one of my songs through Whatsapp and copy anything form my computer as a file), but god, why your hardware is so bad?
Also, a lot of free apps, but very bad designed, just look for any app to listen podcasts, you have to waste 10secs every fucking time to listen your shit, freedom comes with a price no doubt.
- Samsung: I have no idea who want that shit and why, , not satisfaction at all
- Apple: Fucking expensive, have to pay for everything, but quality is much better, hardware is flawless, I have to admit it, my GF has a freaking iPhone 7 and her phone is fine the whole day, on the downside, well, costs and limitations relative to sharing and use
So, I will switch again to fucking Apple, best of the 3 bad evils14 -

When you hear “Haskell performance”, what comes to your mind? I was never really interested in Haskell since I had Clojure, and I thought Haskell might be slow.
Haskell with GHC is actually as fast as C or even faster. Haskell runs right on your hardware, no VM or interpreter.
When a program is small, the performance is comparable to C. Sometimes it’s quicker, sometimes not. But when a program is large, Haskell implementation would be faster if you’re not a robot that generates perfect C code.
It’s both very high-order AND very fast. You don’t need math to code in Haskell.
Too bad there are no kewl libraries.12 -
"hey come try this good chat program called demonsaw"
5 days later:
developer: "i have no idea why it's so unstable for you only, at this point i'd suggest trying a different distro"
me: *tries a bunch of distros* "yeah all of them are just as fucked"
we went through "well is it DS' config? Is it your kernel? systemd? debian misconfig? libs? hardware? network? other shit running? ulimit settings? does Windows do this too? How about OSX?"
i feel so bad but we have no idea what is happening6 -
Hi devRant. Wanna rant with some shit about my company. First some good parts. I work in company with 600+ employees. It's one of the best companies in my region. They provide you with any kind of sweets(cookies, coffee, tea, etc), any hardware you need for your work (additional monitor, more ram, SSDs, processor, graphics card, whatever), just about everything you need to make your work faster/comfortable. Then, we have regular reviews (every 6 months), which rise salary from $0.75 to $1.5 per hour. (I live in poor country, where $15 per hour makes your more solvent then 70% of people, so having 100-200 bucks increase every half year is quite good rise).
The resulting increase of review depends on how team leader and project manager are satisfied with my work. And here starts the interesting (e.g. the shit comes in).
1) Seniority level in our company applies depending on the salary you have. That't right. It does not depend on your skill. Except the case when you're applying to vacancy. So if you tell that you're senior dev and prove it during interview, you'll have senior's salary. This is fine if you're just want money. But not if you love programming (as me) because of reasons bellow.
2) You don't need to have lots of programming experience to be a team leader. You can even be a junior team leader (but thanks god, on research projects only). You start from leading research projects and than move to billable if the director of research department is satisfied with your leading skills.
As a consequence our seniors are dumb AF. This pieces me off the most. Not all of them. A would say half of them are real pro guys, but the rest suck at programming (as for a senior). They are around junior/middle level.
I can understand if guy has $15 rate but still remains junior dev. That's fine. But hell no, he is treated as a middle, because his rate is $10+ now! And his mind has priority over middles and juniors. Not that junior have lof of good tougths but sometimes they do.
I'm lucky to work yet on small project so I'm the only dev, and so to speak TL for myself. But my colleague has this kind of senior team leader who is dumb AF. They work on ASP.NET Core project, the senior does not even know how to properly write generic constraints in C#. Seriously.
Just look at this shit. Instead of
MyClass<T> where T: class {}
he does this:
abstract class EnsureClass {}
MyClass<T> where T: EnsureClass {}
He writes empty abstract class, forces other classes to inherit it (thus, wasting the ability to inherit some useful class) just to ensure that generic T is a class. What thA FUCK is wrong with you dude?! You're a senior dev and you don't even know the language you're codding in.
And this shit is all over the company. Every monkey that had enough skill just to not be fired and enough patience to work 4-5 years becomes a senior! No-fucking-body cares and reviews your skill increase. The whole review is about department director asking TL and PM question like "how is this guy doing? is he OK or we should fire him?" That's the whole review. If TL does not like you, he can leave bad review and the company will set you on trial. If you confront TL during this period, pack your suitcase. Two cases of such shit I know personally. A good skilled guy could not just find common language with his TL and got fired. And the cherry on top of the case is that thay don't care about the fired dev's mind. They will only listen to reviewer. This is just absurd and just boils me down.
That's all i wanted to say. Thanks for your attention. -
I don't wanna be specific today, so I'll just post a song exerpt.
I love you, I hate you, I'm on the fence, it all depends
Whether I'm up or down, I'm on the mend, transcending all reality
I like you, despise you, admire you
What are we gonna do when everything all falls through?
I must confess, I've made a mess of what should be a small success
But I digress, at least I've tried my very best, I guess
This, that, the other, why even bother?
It won't be with me on my deathbed, but I'll still be in your head
Put me on a pedestal and I'll only disappoint you
Tell me I'm exceptional, I promise to exploit you
Give me all your money, and I'll make some origami, honey
I think you're a joke, but I don't find you very funny

Linux vs Windows (vs AnyOtherOS) | The Age Old Question
The short answer: It depends. And probably isn't even up to you to choose
The long answer:
No one's forcing you to choose. And you have more than 2 options. (The 3rd being... both. (Unless you're running out of hardware))
You have to mentally replace "Which is better? Linux or Windows?" with "Which one gets me sooner to a completed task that more closely matches the end-user's expectations"
If it's something you're developing for yourself, then use whatever the hell you want, because you know where you want that "finished product" to be used, and in what manner.
But often, everyone around you and their cats are not using what you're using
Have to write a document? Oh.. there's this blue program thingy (no one talks like that), I think it was called "Microsoft Word"
Oh, you don't have that?? How the hell do you edit documents then?

psd? More like PTSD at this point

Hate Photoshop? Love Gimp? Too bad.
When that god forsaken PSD is emailed to you, you better have a copy of Windows and Photoshop just in case it looks like garbage in.. OR OUT of gimp..
Bottom Line:
Don't use what people use. Just have everything ready in case your boss still uses MS Word 1839 and you want to ENSURE, it'll look the same on his screen
*It's wrong to limit yourself to just ONE SINGLE OS2 -
when programming fails.
when I updated the firmware on this piece, something went wrong and the device broke.
Google'd and learned that the only way to unbrick is to break the other side open and remove a non-removable battery, to reset. else it will stay bricked forever -
Disclaimer: I'm surprisingly bad with hardware.
Bonus will come in soon and its time for a new laptop. Had my xps13 since ~2016 and I absolutely loved it - the keyboard is amaaazing.. But the display is broken and as its a touch, its ridiculously expensive to replace so that's not an option..
Want to keep it around 1k$ and mostly care about the keyboard being nice, robust case (not plastic), size (no bigger than 13") and storage (at least 1TB SSD).
Ideally it would have an integrated SD slot and at least 1 USB-A...
Any suggestions? I'm gonna put Linux on it anyway so performance just has to be medium.
Thinking about getting another xps but they got a good bit more expensive and I know there's other devices our there nowadays that check the boxes, like thinkpad for example.
Just looking for some opinions, advice and suggestions.
Thanks in advance1
