Big event. Massive traffic in production, so we were monitoring all night.
I was in a room with 2 devs of my team, a marketting girl, my boss and a designer... chilling.
Suddenly the production is down.
Boss: production is down, anyone can check?
Me: already on it
Dev1: it looks ok for me
Dev2: me too
Me: wait what? Impossible everything is down
Dev1: oh I refreshed the page it's not working
Me: don't stay on the page refreshing it like you are fucking monkeys. Give me useful intel or be quiet.
Market girl: is it working?
...
Guys is it working?
...
Hello?
Me: Not yet we are looking. Don't distract me.
Boss: client called us. They want it online now.
Dev1&2: he's looking
... 1 min later...
Boss: is it working?
Boss: is it working?
Boss: is it working?
Me: SHUT THE FUCK FOR FUCKING ONE SECOND. ALL OF YOU, OUT NOW. YOU ARE FUCKING MONKEYS WHO CAN'T DO SHIT. IF YOU CAN'T HELP JUST SHUT YOUR DAMN SHITHOLE. DEVS, LOOK WITH ME. MARKET GIRL PREPARE A FUCKING POST-MORTEM MAIL. BOSS GET THE CLIENT ON THE PHONE AND STALE. DO. YOUR. FUCKING. JOBS.
That's how I ended up screaming at everyone... the rest of the night went in complete silence and I fixed the issue 2min after the got quiet or busy.24 -

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.
For updates refer the kernel tree: https://git.kernel.org/…/ke…/...

A group of Security researchers has officially fucked hardware-level Intel botnet officially branded as "Intel Management Engine" they did so by gathering it all the autism they were able to get from StackOverflow mods... though they officially call it a Buffer Overflow.
On Wednesday, in a presentation at Black Hat Europe, Positive Technologies security researchers Mark Ermolov and Maxim Goryachy plan to explain the firmware flaws they found in Intel Management Engine 11, along with a warning that vendor patches for the vulnerability may not be enough.
Two weeks ago, the pair received thanks from Intel for working with the company to disclose the bugs responsibility. At the time, Chipzilla published 10 vulnerability notices affecting its Management Engine (ME), Server Platform Services (SPS), and Trusted Execution Engine (TXE).
The Intel Management Engine, which resides in the Platform Controller Hub, is a coprocessor that powers the company's vPro administrative features across a variety of chip families. It has its own OS, MINIX 3, a Unix-like operating system that runs at a level below the kernel of the device's main operating system.
It's a computer designed to monitor your computer. In that position, it has access to most of the processes and data on the main CPU. For admins, it can be useful for managing fleets of PCs; it's equally appealing to hackers for what Positive Technologies has dubbed "God mode."
The flaws cited by Intel could let an attacker run arbitrary code on affected hardware that wouldn't be visible to the user or the main operating system. Fears of such an attack led Chipzilla to implement an off switch, to comply with the NSA-developed IT security program called HAP.
But having identified this switch earlier this year, Ermolov and Goryachy contend it fails to protect against the bugs identified in three of the ten disclosures: CVE-2017-5705, CVE-2017-5706, and CVE-2017-5707.
The duo say they found a locally exploitable stack buffer overflow that allows the execution of unsigned code on any device with Intel ME 11, even if the device is turned off or protected by security software.

Client: "we need a piece of software to have our son be able to talk again"
Me: "what can your son do physically?"
Client: "He can only grip something"
Me: "well, I suppose that is possible by using Intel ACAT, some synthesizer and some switches"
Client: "Never heard of ACAT, probably some small program that nobody else heard of"
Me: "It was used by a great man called Stephen Hawking. If it worked for him, it should work for your son"
Client: "Who is Stephen Hawking?"

Absolutely hate the awful Machines we have to code on at the office, went through three laptops in the space of a year.
All of the them the exact model and specs probably purchased from some tech museum. They would hang and BSOD several times a day and made me look bad when my bit of code wasn't ready on time for a delivery.
Lol , even running spotify while running a couple of dev tools wasn't possible without causing the music to stutter.
After a year i managed to get my hands onto an old Dell desktop when a colleague left that had better specs that would sort of do the job. Wished i could reformat it but alas we aren't allowed to do anything remotely like that.
Finally got fed up of it all, since i bought myself a little treat, an Intel Skull canyon.
Awesome little piece of kit , pretty damn powerful and looks cool too.
Oh an on quiet afternoons I do get to game a little 🤗
The integrated iris pro gpu is surprisingly powerful, it can handle some of the older AAA titles although I haven't really put it through the test yet.
i leave it in the office
Secured with a kensingon lock and locked in my desk drawers

Monday morning, went to the local grocery store to get myself some croissants and 2 bottles of wine.
Cashier: "Already at it in the morning, you sure about that?"
Me: "Long story short, I've got a Wi-Fi driver from Intel to debug and rewrite, and it's a fucking piece of shit.. can't go at it without hitting or preferably exceeding the Ballmer Peak... Also I'm awake since yesterday evening already."
Why even ask? Yeah I'm a fucking alcoholic, and guess why that is.. stupid nontechnical fucks, certified enganeers like that motherfucker at Intel who wrote this pile of garbage called ipw2200, and technology that can't be arsed to work properly on its own unless I build the fucking thing myself, just to name a few reasons.
You know what, fucking piece of shit from Intel, whoever it is? How about I let you choke on my dick while fucking hanging you with a sharp metal wire that's carrying 2kVAC from a microwave transformer, just to see whether I'd nut first, or you either choke, get electrocuted, or get your fucking throat slit first. Certificates aren't an excuse for committing this fucking pile of shit and calling it a fucking product!!
Now, it's time to dive into this giant stinking fucking turd I guess.. first glass of wine to get myself prepared for the shitstorm that's a giant 20k LoC C file with barely any comments, to look what the fuck causes this fucking pile of shit to disconnect and ask for WPA credentials after a while, despite having them stored.. and not reconnect after that, because why the fuck would you?!10 -
I have a new woman in my life. She has an amazing contoured body, smooth to touch and yeah she is wonderful on the inside. She is a pleasure to be around and is always there for me. She enables to DO amazing things and she empowers my personal aswell as my professional development. I THINK I'm falling in love no I DO love her.
She is my Lenovo ThinkStation P310 Intel Xeon 3.60GHz 32GB RAM 1.2TB SSD 6GB/s also known as Suzie.9 -
Why people keep installing shit on their computers and then asks me if I can fix their PC that "randomly" stopped to run as fast as before?
If you, fucking retard, installed combos of 2 or sometimes even 3 antivirues, the worst ones by the way (e.g. Avast + Norton + Avira), some bullshit utilites like BoostMyFuckingPC 9000, SpeedMyGPU, etc. it's normal that it doesn't work, especially if you have a low end laptop with Intel i3 and 4 GB of RAM…
And it's not true I'm a magician if I make it work properly again, I just undone the fucking decisions you made when you started to search on bing how to increase FPS in LoL…
Fuck you, and fuck me because since we're friends/relatives I HAVE to help you little bastard.6 -
This happend to me around 2 weeks ago. For some reason, I decied to post this now.
I won the lottery, yey! I mean, bot really, but I am <19yo student, "less than junior dev" in my office, but sonce I am the only one who is capable of working with hardware, I was working month back as a sysadmin for a few days. Our last sysadmin was really good working but really, really toxic guy, so he got fired on a spot after argument with some manager or whatever, no big deal, we could have another guy hired in a week. But, our backup server literally was on fire, all data probably dead because bad capacitor or whatever. This was our only backup of everything at the time. Everyone in full fucking panic mode, we had literally no other working HW we could use for backup, but then comes me, intern employed on his first dev job for 3 months. That day I bought some HW for my own personal server at home (Intel NUC with some Celeron, 4GB DDR4 RAM and two 240GB SSDs for RAID 1. My manager asked everyone in the office for sollution how to survive next 4 days before new server arrives. People there had no idea what tk do and no knowedgle about HW, I just came from a break and offered my components for a week, since there was noone else who can work with HW, servers and stuff like this, manager offered me $500+HW cost if I, random intern, can make it work. I installed Debian on that little PC, created RAID1 from both SSDs, installed MySQL server and mirrored GIT server from our last standing server (we had two before one of them went lit 🔥), made simple Python script to copy all data on that RAID, with some help of our database guy copied whole DB from production to this little computer and edited some PHP so every SQL request made on our server will run on that NUC too. Everything after ±2 hours worked perfectly. Untill a fucking PSU burned in our server and took RAID controller with him in sillicon heaven next night, so we could not access any data unltill we got a new one. Thanks to every god out there, I was able to create software RAID from survived HDDs on our production server and copy all data from that NUC on the servers software RAID and make it working at 3 AM in the night before an exam 😂. Without this, we would be next ±40 hours without aerver running and we might loose soke of our data and customers. So my little skill with Linux, Python, MySQL and most importantly my NUC hardware I got that day running as a backup server saved maybe whole company 😂.
Btw, guess who is now employee of the year with $2500 bonus? 😀
Sorry for bragging and log post, but I was so lucky an so happy when everything worked out, good luck to all sysadmins out there! 👍
TL:DR: Random intern saved company and made some money 😂7 -
I attended a data science meetup recently. There were many suits walking around the corridors because of some startup night taking place at the same time.
After some time a guy appeared infront of me, telling me he was afraid at first that this was a meetup for suits only. Until he saw all the dev and rock stickers on my notebook. He was reliefed that there was some nerd at least.
He asked what I was doing so I told him about my startup about optimization of heat generation plants jada jada. I asked him back.
He replied, "Well, I'm also part of some small startup. Among the things we develop processors and stuff. It's called Intel."
Well dude, that was nicely played. I had a lot of fun that evening.5 -
Fucking cloud providers always trying to steal your shit and spy on your things, fucking prying eyes. That's why i've decided to go back hosting my own private cloud from home. Running on some very energy efficient shit: dual core intel atom cpu (so slow that it can't fucking run windows normally), 16gb of ram, because why the fuck not? and 1tb 2.5"hdd, along with unlimited data - 100/100 Mbit/s internet connection with a server response time less than 95ms just to backup my shitty Iphone selfies and cat pics, host some very important files and regularly back up my contacts. This shit runs CentOS, Nginx, https, bitch! This platform is more trustworthy than your shitty dropbox or whatever other shit they offer you. I can choose whether i back-up my shit from local network or over internetz, Costing me no more than 25€ annually(just to keep the machine on 24/7/365).14

Lots of fun open source stuff, but I had a lot of fun working on a survey taking m&m dispenser. The goal was to encourage students to answer survey questions that would help the faculty get a better idea of what the students found most valuable (different things they wanted to learn, classes they found useless, etc.). So me and another student built this :) Its a node server running on an Intel Galileo, which served up an admin and survey interface using React. When a student answered a survey question, a servo would turn a gear, which interfaced with a rack and pinion that had two little pits in it. When it would slide under the jar, two m&ms would fill the pits, then the rack and pinion would push them out. Then we had a webcam hooked up to the end of it that would compare the colors of the m&ms to see if they were the same. If they were the same, the student would get more m&ms. The gear pieces were 3D printed.
We could never get the webcam stuff to work right with the Galileo because OpenCV (the computer vision library we were using to interact with the webcam) could not be built/compiled on such a specific version of Linux. Later, I was able to do it with a RaspberryPi, but never got it reintegrated.5 -
I do not like the direction laptop vendors are taking.
New laptops tend to feature fewer ports, making the user more dependent on adapters. Similarly to smartphones, this is a detrimental trend initiated by Apple and replicated by the rest of the pack.
As of 2022, many mid-range laptops feature just one USB-A port and one USB-C port, resembling Apple's toxic minimalism. In 2010, mid-class laptops commonly had three or four USB ports. I have even seen an MSi gaming laptop with six USB ports. Now, much of the edges is wasted "clean" space.
Sure, there are USB hubs, but those only work well with low-power devices. When attaching two external hard drives to transfer data between them, they might not be able to spin up due to insufficient power from the USB port or undervoltage caused by the impedance (resistance) of the USB cable between the laptop's USB port and hub. There are USB hubs which can be externally powered, but that means yet another wall adapter one has to carry.
Non-replaceable [shortest-lived component] mean difficult repairs and no more reserve batteries, as well as no extra-sized battery packs. When the battery expires, one might have to waste four hours on a repair shop for a replacement that would have taken a minute on a 2010 laptop.
The SD card slot is being replaced with inferior MicroSD or removed entirely. This is especially bad for photographers and videographers who would frequently plug memory cards into their laptop. SD cards are far more comfortable than MicroSD cards, and no, bulky external adapters that reserve the device's only USB port and protrude can not replace an integrated SD card slot.
Most mid-range laptops in the early 2010s also had a LAN port for immediate interference-free connection. That is now reserved for gaming-class / desknote laptops.
Obviously, components like RAM and storage are far more difficult to upgrade in more modern laptops, or not possible at all if soldered in.
Touch pads increasingly have the buttons underneath the touch surface rather than separate, meaning one has to be careful not to move the mouse while clicking. Otherwise, it could cause an unwanted drag-and-drop gesture. Some touch pads are smart enough to detect when a user intends to click, and lock the movement, but not all. A right-click drag-and-drop gesture might not be possible due to the finger on the button being registered as touch. Clicking with short tapping could be unreliable and sluggish. While one should have external peripherals anyway, one might not always have brought them with. The fallback input device is now even less comfortable.
Some laptop vendors include a sponge sheet that they want users to put between the keyboard and the screen before folding it, "to avoid damaging the screen", even though making it two millimetres thicker could do the same without relying on a sponge sheet. So they want me to carry that bulky thing everywhere around? How about no?
That's the irony. They wanted to make laptops lighter and slimmer, but that made them adapter- and sponge sheet-dependent, defeating the portability purpose.
Sure, the CPU performance has improved. Vendors proudly show off in their advertisements which generation of Intel Core they have this time. As if that is something users especially care about. Hoo-ray, generation 14 is now yet another 5% faster than the previous generation! But what is the benefit of that if I have to rely on annoying adapters to get the same work done that I could formerly do without those adapters?
Microsoft has also copied Apple in demanding internet connection before Windows 11 will set up. The setup screen says "You will need an Internet connection…" - no, technically I would not. What does technically stand in the way of Windows 11 setting up offline? After all, previous Windows versions like Windows 95 could do so 25 years earlier. But also far more recent versions. Thankfully, Linux distributions do not do that.
If "new" and "modern" mean more locked-in and less practical and difficult to repair, I would rather have "old" than "new".12 -
5 stages of failing WIFI connectivity on Linux
This morning I woke up my laptop to start my work day. I have 2 very important meetings today, so I better get all prepared.
"Wifi connection failed"
Syslog says:
- wpa_supplicant: wlp9s0: SME: Trying to authenticate with <MAC>
- kernel: wlp9s0: authenticate with <MAC>
- kernel: wl9s0: send auth to <MAC> (try 1/3)
- kernel: wl9s0: send auth to <MAC> (try 2/3)
- kernel: iwlwifi: Not associated and the session protection is over already...
- kernel: wl9s0: send auth to <MAC> (try 3/3)
- kernel: wl9s0: authentication with <MAC> timed out
#### DENIAL #####
No biggie, let's try another AP (I have 3). All 3 failed to connect. Fine, let's try my phone's hotspot! FAILED!!!!!
w00t.... okay, let's restart the router... but failing to connect to a phone hotspot is already a worrying sign.
Wifi connection failed
wtf.. disable and re-enable wifi
Wifi connection failed
#### ANGER #####
the fuuuuuuck. Maybe my router is dead. But my phone connects to it, no fuss. My personal lappy also connects there easily.
wtf... Does that mean I'm about to lose my uptime?? Come one!! It's Linux - there MUST be something I could do! I don't see processes hanging in D state so the radio must be fine - it's gotta be a software issue!
ChatGPT – type all the log entries manually, via phone (that took a while...). Nothing useful there: update firmware, restart NetworkManager, etc.
#### BARGAINING #####
Alright... How about a USB dongle? Plug it in and wifi connects immediately! Yayyy!!! But that's only b/g/n and I'd very much like to have ac. It works well as a limping backup, but not something I'd use for the meetings.
rfkill block/unblock all the radios. No change. USB dongle connects right away but the PCIe adapter keeps throwing notifications at me with failure messages. It's annoying, to say the least.
So I've already tried
- restarting the router(s)
- disabling/reenabling the radios
- multiple APs
- suspending/waking again several times
- praying
#### DEPRESSION #####
The only thing I haven't tried yet is the most cruel one - restarting the laptop. But that's unfair... It's LINUX! How could it disappoint me. I have so many tmux sessions open, so many unsaved leafpad notes, terminal histories with oh so comfy ^r and ! retriggers all ready and waiting to be executed...
#### ACCEPTANCE #####
But I can't miss the meeting. So I slowly start closing off apps, starting with the least important ones, trying to preserve as much history and recent commands as I can. I'm gonna lose my uptime, that's the inevitable obvious truth... Linux has failed me. Or maybe it's a hardware issue... I can't be sure until I restart.
I must reboot.
#### A NEW HOPE #####
Hold on.. What if... What if before restarting I try to reload the Intel wifi kernel module? Just for the giggles. I've got nothing to lose anyway...
rmmod iwlmvm
rmmod iwlwifi
modprobe iwlwifi
modprobe iwlmvm

Probably a little different shitty teacher!
Had a course in basic computer architecture and the teacher was way to over qualified to have that course. This is a guy who presents his research to Nvidia and Intel but is forced to teach a intro level course...
The result? He was completely unmotivated and unprepared for the lectures and was of no help on the assignments. Fortunately we had a awesome teaching assistant who saved the entire course for me and my friends. Seriously, kudos to that guy!1 -
Fuck you Intel.
Fucking admit that you're Hardware has a problem!
"Intel and other technology companies have been made aware of new security research describing software analysis methods that, when used for malicious purposes, have the potential to improperly gather sensitive data from computing devices that are operating as designed. Intel believes these exploits do not have the potential to corrupt, modify or delete data"
With Meltdown one process can fucking read everything that is in memory. Every password and every other sensible bit. Of course you can't change sensible data directly. You have to use the sensible data you gathered... Big fucking difference you dumb shits.
Meltown occurs because of hardware implemented speculative execution.
The solution is to fucking separate kernel- and user-adress space.
And you're saying that your hardware works how it should.
Shame on you.
I'm not saying that I don't tolerate mistakes like this. Shit happens.
But not having the balls to admit that it is because of the hardware makes me fucking angry.5 -
Lessons I've learnt so far on programming
-- Your best written code today can be your worst tomorrow (Focus more on optimisation than style).
-- Having zero knowledge of a language then watching video tutorials is like purchasing an arsenal before knowing what a gun is (Read the docs instead).
-- It's works on my machine! Yes, because you built on Lenovo G-force but never considered the testers running on Intel Pentium 0.001 (Always consider low end devices).
-- "Programming" is you telling a story and without adding "comments" you just wrote a whole novel having no punctuation marks (Always add comments, you will thank yourself later for it I promise).
-- In programming there is nothing like "done"! You only have "in progress" or "abandoned" (Deploy progressively).
-- If at this point you still don't know how to make an asynchronous call in your favourite language, then you are still a rookie! take that from me. (Asynchronous operation is a key feature in programming that every coder should know).
-- If it's more than two conditions use "Switch... case" else stick with "If... else" (Readability should never be under-rated).
-- Code editors can MAKE YOU and BREAK YOU. They have great impact on your coding style and delivery time (Choose editors wisely).
-- Always resist the temptation of writing the whole project from scratch unless needs be (Favor patching to re-creation).
-- Helper methods reduces code redundancy by a large chunk (Always have a class in your project with helper methods).
-- There is something called git (Always make backups).
-- If you don't feel the soothing joy that comes in fixing a bug then "programming" is a no-no (Coding is fun only when it works).
-- Get angry with the bugs not the testers they're only noble messengers (Bugs are your true enemy).
-- You would learn more than a lot reading the codes of others and I mean a lot! (Code review promotes optimisation and let's you know when you are writing macaroni).
-- If you can do it without a framework you have yourself a big fat plus (Frameworks make you entirely dependent).
-- Treat your code like your pet, stop taking care of it and it dies! (Codes are fragile and needs regular updates to stay relevant).
Programming is nothing but fun and I've learnt that a long time ago.6 -
YOU. If you can't be arsed to change the default wallpaper, the terminal/gtk theme on a fucking laptop you use everyday, turn off Intel graphics screen rotation shortcuts, move the taskbar somewhere, install a Vue.js/Augury (Angular tool) Chrome plugin so you can actually debug stuff, Git for Windows or even this fucking trash of a player that is VLC, comb your hair the other way for once in your fucking lifetime if you have it, buy a different shirt than the same one you already have, fucking anything at all - fuck you!
BTW Don't be surprised when I don't take your fucking advice about the layout of the site I'm working on.
Also I secretly FUCKING HATE YOU just because.
Nothing personal kiddo. Except it is.
Fucking go out there and make the world around more suited to your tastes, every fucking human has them! Just change the fucking wallpaper, so I'll know you have at least a little bit of fucking personality in you! Slap a pic of some hi-rez tits on that screen! ANYTHING AT ALL.

I started working at my company a year ago.
Back then I was just graduating from sofware engineering degree.
The position was Junior Web Dev, But actually it is full stack developer.
When I joined I wanted salary X (because I "got offers"), which was a bit above what big companies like Intel gives to graduates back then.
The offered back 80% of it, which was a bit more than was most graduates got in startups.
I settled on their offer and we agreed that after a year I'll get the raise if I'll do good.
A year passed.
The team leader left for a bigger company, and I became the unofficial team leader (and was always the scrum master )
Bare in mind that there are two developers that are in the company for 2-3 years, yet I got the unofficial roll.
We had the talk, and my manager asked me straight away "under what salary would you start to search other jobs? We want to keep you here"
I said that under my initial X salary that we agreed a year ago.
He claimed to have forgotten that we agreed on 20% raise.
I answered that it's the least I ask, beneath it and I'll start looking for another job.
He replied that he'll do his best to make the owner give me that.
A week passed and I got no update....
What should I do in your opinion?12 -
Can someone help me understand?
I subscribed to a nifty IT-releated magazine, and on its back, there's an ad for "Dedicated root server hosting", nothing unusual at a first glance, but after I read the issue, I decided to humor them and see what it is that they offered, and... It just... Doesn't make sense to me!
An ad for "Dedicated Root Server" - What is a dedicated root server first of all? Root servers of any infrastructure sound pretty important.
But, the ad also boasts "High speed performance with the new Intel Core i9-9900K octa-core processor", that's the first weird thing.
Why would anyone responsible enough want to put an i9 into a highly-reliable root server, when the thing doesn't even support ECC? Also, come on, octa-core isn't much, I deal with servers that have anywhere between 2 and 24 cores. 8 isn't exactly a win, even if it has a higher per-core clock.
Oh, also, further down the ad has a list of, seeming, advantages/specs of the servers, they proclaim that the CPU "incl. Hyper-Threading-Technology"... Isn't that... Standard when it comes to servers? I have never seen a server without hyperthreading so far at my job.
"64 GBs of DDR4 RAM" - Fair enough, 64 gigs is a good amount, but... Again, its not ECC, something I would never put into a server.
"2 x 8 TB SATA Enterprise Hard Drive 7200 rpm" - Heh, "enterprise hard drive", another cheap marketing word, would impress me more if they mentioned an actual brand/model, but I'll bite, and say that at least the 7200 rpm is better than I expected.
"100 GBs of Backup Space" - That's... Really, really little. I've dealt with clients who's single database backup is larger than that. Especially with 2x8 TB HDD (Even accounting for software raids on top)
This one cracks me up - "Traffic unlimited"
Whaaaat?! You are not gonna give me a limit to the total transferred traffic to the internet for my server in your data center? Oh, how generous of you, only, the other case would make the server just an expensive paperweight! I thought this ad was for semi-professionals at least, so why mention traffic, and not bandwidth, the thing that matters much more when it comes to servers? How big of a bandwidth do I get? Don't tell me you use dialup for your "Dedicated Root Server"s!
"Location Germany or Finland" - Fair enough, geolocation can matter when it comes to latency.
"No minimum contract" - Oooh, how kiiiind of you, again, you are not gonna charge me extra for using the server only as long as I pay? How nice!
"Setup Fee £60" - I guess, fair enough, the server is not gonna set itself up, only...
The whole ad is for "monthly from £55.50", that's quite the large fee for setup.
Oh, and a cherry on top, the tiny print on the bottom mentions: "All prices exclude VAT and are a subject to..." blah blah blah.
Really? I thought that this sort of almost customer deceipt is present only in the common people's sphere!
I must say, there's being unimpressed, and then... There's this. Why, just... Why? Anyone understands this? Because I don't...12 -
Ye, so after studying for an eternity and doing some odd jobs here and there, all I can show for are following traits:
* Super knowledgeable in arm/Intel assembly language
* C-Veteran with knowledge of some sick and nasty C-hacks/tricks which would even sour the mood of your grandma
* Acquired disdain of any and all scripting languages (how dare you write something in one line for which I need a whole library for!)
* All-in-all low-level programmer type of guy (gimme those juicy registers to write into!)
After completing the mandatory part of my computer science studies, all I did was immerse myself into low-level stuff. Even started to hold lectures and all.
Now I'm at the cusp of being let free into the open market.
The thing is: I'm pretty sure that no company is really interested in my knowledge, as no one really writes assembly anymore.
Sure, embedded programming is still a thing, but even that is becoming increasingly more abstract, with God knows how many layers of software between the hardware and the dev, just to hide all the scary bits underneath.
So, are there people in here who're actually exposed to assembly or any hands-on hardware-programming?
Like, on a "which bit in which register/addr do I need to set" - kind of way.
And if so, what would you say someone like me should lookout for in a company to match my interest to theirs?
Or is it just a pipe dream, so I'd need to brace myself to a mundane software engineer career where I have to process a ticket at a time?
(Just to give a reference: even the most hardware-inclined companies I found "near" me are developing UIs with HTML5 to be used in some such environment ....)12 -
I was on a interview two weeks ago, got a mail today that I had been selected to the third round (government intel stuff)
I got clean sheet from the police and the "Security Service" in the country.
And now, in the mail. The recruiter wanted me to give contacts to my current boss. I am one of 4 and I dont want to sacrifice the trust that my boss have on me.
What the '''' should I do?2 -
Install 18.04 they said. It will be fine they said...
Well.
Apperently it hates my intel graphics card. It was giving me artifacts already during installation. It didnt boot after installation and got stuck on a purple screen with the mouse on it.
Got past that with recovery mode. Googled the solution snd they said "move mouse while booting" yeah that doesn't help.
It also didn't recognize the other monitors connected to it and since it comes without unity now everything was not where I'm used to look for it.
3 hours of grub mangleing, driver installing and a unity installation later, it finally works.
Installed terminator and oh, look, one of the most used short cuts is overwritten by some emoji pick bs.
Ffs.
Longest ubuntu installtion ever and it almost fked up the 16.04 aswell which is in dual boot atm.
And before someone says use Arch: ubuntu is a project requirement and Arch is not supported by the tools we need to use.12 -

Guys, we need talk raw performance for a second.
Fair disclaimer - if you are for some reason intel worker, you may feel offended.
I have one fucking question.
What's the point of fucking ultra-low-power-extreme-potato CPUs like intel atoms?
Okay, okay. Power usage. Sure. So that's one.
Now tell me, why in the fucking world anyone would prefer to wait 5-10 times more for same action to happen while indeed consuming also 5-10 times less power?
Can't you just tune down "big" core and call it a day? It would be around.. a fuckton faster. I have my i7-7820HK cpu and if I dial it back to 1.2Ghz my WINDOWS with around lot of background tasks machine works fucking faster than atom-powered freaking LUBUNTU that has only firefox open.
tested i7-7820hk vs atom-x5-z8350.
opening new tab and navigating to google took on my i7 machine a under 1 second, and atom took almost 1.5 second. While having higher clock (turbo boost)
Guys, 7820hk dialled down to 1.2 ghz; 0.81v
Seriously.
I felt everything was lagging. but OS was much more responsive than atom machine...
What the fuck, Intel. It's pointless. I think I'm not only one who would gladly pay a little bit more for such difference.
i7 had clear disadvantages here, linux vs windows, clear background vs quite a few processes in background, and it had higher f***ng clock speed.
TL;DR
Intel atom processors use less power but waste a lot of time, while a little bit more power used on bigger cpu would complete task faster, thus atoms are just plain pointless garbage.
PS.
Tested in frustration at work, apparently they bought 3 craptops for presentations or some shit like that and they have mental problems becouse cheapest shit on market is more shitty than they anticipated ;-;
fucking seriously ;-;16 -
Well, I wanna specialize in low-level software as I get older. Everyone is telling me to go out and learn a processor architecture. I'm willing to be patient, so I do what people recommend to me and I download the Intel x86_64 manual. I was excited... UNTIL I REALIZED THE MANUAL WAS 4474 PAGES LONG! Like, how am I supposed to jump into assembly, machine language, and low-level programing with a beginner's task like that? I cannot find ANY resources online to simplify the transition, and college sure ain't gonna teach me anytime soon.10

Any other Screeps players here?
for the people running into a "Screeps is not defined":
Screeps is a MMO RTS where you code your "army" to do stuff in Javascript (a la NodeJS).
Code how your harvesters should behave, how your soldiers should behave, how your builders should behave etc. etc.
So far, it is quite a fun game, tho my (Intel Nehalem based) laptop has issues handling it (thanks to a awfully slow GPU...) so it's difficult to play for me at the moment (I'm on holiday, my home PC is a LOT faster).
It costs about 15 euro on steam, and if you're into this stuff, it's well worth it.
Just make sure you finish the tutorial first... I didn't and I regretted it when I bought the game (it's a huge pain in the buttocks to get started if you don't understand the API and such).
Currently just playing on my own localhosted private server to discover how the game works and such, but will be setting up a public server later down the road to play with others.
Tho it would be nice if Screeps would allow for "team-based" gameplay as well so it'll be slightly harder for early players to bully the newer ones.2 -

Can anyone help me choose an antivirus for Windows ? If it is free it would be great !!
I am a full time linux lover, but I have to set up a windows pc for my parents, possibly win 7 on Intel NUC with atom processor.

A Rant that took my attention on MacRhumors forum.
.
I pre-calculated projected actual overall cost of owning my i5/5/256 Haswell Air, which I got for $1500.
After calculations, this machine would cost me about $3000 for 3 years of use.
(Apple Care, MS Office Business, Parallels, Thunderbolt adapter to HDMI, Case... and so on).
Yea... A lot of people think it's all about the laptop with Apple. nah... not at all. There's a reason Apple is gradually dropping the price of their laptops.
They are slowly moving to a razor and blade business model... which basically is exactly what it sounds like - you buy the razor which isn't too expensive, but you've got no choice but to buy expensive additional blades.
I doubt Apple is making much money from laptop sales alone... well definitely not as much as they were making 5 years or so ago (remember the original air was about $1800 for base model, and if i remember correctly - $1000 additional dollars to upgrade to 64GB SSD from the base HDD.
Yes, ONE THOUSAND DOLLARS FOR 64GB SSD!
Well, anyways, the point is that Apple no longer makes them BIG bucks from the laptop alone, but they still make good profits from upgrades. $300 to go to 512GB SSD from 256, $100 for 4GB extra ram, and $150 for a small bump in processor. They make good profits from these as well.
But that's not where they make mo money. It's once you buy the Macbook, they've got you trapped in their walled garden for life. Every single apple accessory is ridiculously overpriced (compared to market standards of similar-same products).
And Apple makes their own cables and ports. So you have to buy exclusively for Apple products. Every now and then they will change even their own ports and cables, so you have to buy more.
Software is exclusive. You have no choice but to buy what apple offers... or run windows/linux on your Mac.
This is a douche level move comparable to say Mircrosoft kept changing the usb port every 2-3 years, and have exclusive rights to sell the devices that plug in.
No, instead, Intel-Microsoft and them guys make ports and cables as universal as possible.
Can you imagine if USB3.0 was thinner and not backwards compatible with usb2.0 devices?
Well, if it belonged to Apple that's how it would be.
This is why I held out so long before buying an apple laptop. Sure, I had the ipod classic, ipod touch, and more recently iPad Retina... but never a laptop.
I was always against apple.
But I factored in the pros and cons, and I realized I needed to go OS X. I've been fudged by one virus or another during my years of Windows usage. Trojans, spywares. meh.
I needed a top-notch device that I can carry with me around the world and use for any task which is work related. I figured $3000 was a fair price to pay for it.
No, not $1500... but $3000. Also I 'm dead happy I don't have to worry about heat issues anymore. This is a masterpiece. $3000 for 3 years equals $1000 a year, fair price to pay for security, comfort, and most importantly - reliability. (of course awesome battery is superawesome).
Okay I'm going to stop ranting. I just wish people factored in additional costs from owning an a mac. Expenses don't end when you bring the machine home.
I'm not even going to mention how they utilize technology-push to get you to buy a Thunderbolt display, or now with the new Air - to get a time capsule (AC compatible).
It's all about the blades, with Apple. And once you go Mac, you likely won't go back... hence all the student discounts and benefits. They're baiting you to be a Mac user for life!
Apple Marketing is the ultimate.

Rant on me myself.
After being a professional coder (ie having a bachelor degree) for 11 years now, I finally have a decent and reasonable backup.
I use borg to backup to my raid 1, which is local, in my corridor near the ceiling. I use a Intel NUC with two external USB3 HDDs attatched. As I already had data on them, I went for a btrfs raid 1.
The second level of my backup solution is my brother. It's 50km to his flat. He's got a banana pi with my third HDD attached. I connect to his pi via VPN. The VPN is done via an AVM Fritz! Box. No ads, I just like those boxes (modem and router).
The backup is encrypted, of course.
Now, after ten years, I finally got a decent backup solution. Wow. This feels great! 😎 -
TL;DR: intel stripped the hosted network function from the drivers for my wifi chip. Older versions can still so it
Every month I travel by bandbus to neighbouring countries for a show.
This usually takes 7+ hours.
So i have my laptop with me and if my brother is along as well, we game in the bus.
Using a cable for internet connection isnt handy, since we sit on opposite sides of the bus. So i looked up if I can use a hosted wifi network for this.
We both checked out our drivers and both said no hosted network support.
And some posts on the internet said that customer support told them that the chip can't do it
But thats weird. My laptop is high end. So I searched a little only to find out that I can do a hosted wifi network if I DOWNGRADE my drivers.....
Fuck you intel. Fuck you hard for stripping that function from the drivers1 -

When you your computers graphics card keeps crashing the computer.

The next 2 seconds involve me trying to type in device into start menu... Next I will type in manager.

Hey fellow devRanters,
I'm sure some of you have read about the newest vulnerabilities in Intels Management Engine (ME). I feel like ME and similar "features" are unacceptable backdoors into our systems. Unfortunately Intel and AMD do not offer their customers the option to acquire CPUs that lack these backdoors and make disabling them rather impossible 😒
Thus my question: Do you guys know of any 64-bit "open-source" CPU on the market that is production-ready and suitable for high-traffic web applications? Please note that I don't consider FPGAs to be viable options, since I don't trust Xilinx and Altera either.15 -
Boss assigned code cleanup to me. We put up eslint and fixed a couple of issues, all nice and cute. Now, he wants me to find any redundant code and remove it (redundant fields in config objects). Sounds doable right?
WRONG!
Because we're writing fucking ExtJS. This abomination that is still called a "web framework" in lieu of its former glory supports no typescript, no code intel, no JSDoc, no nothing. Absolutely heinous and deplorable. Add insult to injury, our code on it is even worse. NO single component reused except from a couple REALLY fucking badly written ones, because every component queries for shit outside its jurisdiction so it's all a dependency spaghetti. Everything else is just copy-paste. Barely anything works as intended anymore in this bloody joke of an app.
I tell him in a meeting, I can prepare an automated solution. Some script or something that runs on a file watcher. All nice and dandy. A weekend and a Monday later, I get tired and do something else to clear up my mind. Show him some progress in that other thing. He's like:
Boss: that's good and all but did you remove *insert misused config that got everywhere during copy paste* like I told you to?
Me: I'm still working on it. I switched cause I got tired a bit with the automation.
Boss: automation?
Me: We were talking about in the meeting. *Explains again*
Boss: That's not what we agreed upon
Mfw I've been rambling uselessly on the meeting about it just for you to put me down and make me remove all that copy pasted GUNK from the melting hot garbage that is our codebase BY HAND? All the 150 occurrences of it? What do you think I am, a fucking robot?2 -
Oh, me? I am so excited about all the computing power that's gonna be stolen from people who had updated their Intel CPUs last month.

Intel 8085 micro-processor, anyone?
In my graduation, one of the semesters had Intel 8085 programming in the curriculum. It's because of that dev-kit I understood what assembly-level language means.
A simple scenario of adding two numbers would result in half a page long sequence of commands that literally didn't excuse any mistakes.
It made me understand the semantics or basically what we get taught as "middle level" languages.
We had to memorize the exact pins of the thing and had to draw it from memory. And we had to learn the instruction set it had.
Later we had to learn Intel 8086 but its instruction set was way too complicated and I gave up on it.
I know it sounds geeky but I randomly remembered it today.13 -

Yet three other flaws...
Now it's pretty clear that Intel, either kept their backdoors pretty much knowingly and patch them when they find a better way to access data(yes I see you the functioning of ME) or it's like in the race of faster clock, took the safety of the data for granted.
Anyways, one word, Assholes. The management of Intel -
Are you fucking kidding me?
Just read about Intel ME (I'm trying to secure my computer). Why the holy fuck does Intel need something that powerful? FUCK YOU, CORPORATE BASTARDS IN SUITS THAT RESEMBLE MATRIX AGENTS.

Me : "What are these files on the c: ? I'll move them into a folder"

Have defective supermicro server, but the ipmi is working and could tell me what's going on.
Only problem is, I don't have access to it since the last owner didn't provide it to me.
So I thought let's try metasploit.
Setup local network with a second server, connect to local* address.
"Welcome to intel integrated BMC web console"
What? Its a Supermicro, did the owner reflash the ipmi? What the heck.
Msf: scan adress ....
ipmi found bla bla bla.
Msf: zero cipher scan.
... Voulnerable to zero cipher.
Was pretty happy but the doubt kept creeping in.
On my WS that isn't connected to the ipmi of my server, I go to that ip address.
Bam
"Welcome to intel BMC ......"
MOTHERFUCKER.
What are the odds that some fucker has his ipmi open to the public on that exact same address that my board was configured to.
Well, actually pretty high I guess.
Fuck. Shit.
That didn't go as planned. -

Then I setup dhcp (I really don’t know what I’m doing, just following the tutorial), the ltsp configs thing, build the client image and then, I HAVE NO FUCKING INTERNET CONNECTION. Continues, boot up the thin client... WHY CAN’T YPU FUCKING FIND THE SERVER!! Then I realise the vm is not an ubuntu one, so delete it and make a new one... WHY DOES IT STILL DOESN’T WORK!!!!!! Oh wait forgot to connect to the network! Goes to put the network adaptor, and: wait! I don’t need NAT! So I replace the NAT by the correct network, and: Wait it lets me choose the weird thingy intel/pce thingy, oh I remember now! It said we needed the “...III FAST...”! Activate it and... IT WORKS ! !!!! CONNECTS TO THE SERVER!!! GOT THE DHCP!!! WAIT!!!!! What is THAT 🤬 TFTP LOADING THING!!!:

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 -
I feel like writing or telling people about the time I jumped from Windows 7 Ultimate and jumping to Windows 10. (I'm not against 10, but I'm never updating after what had happened to me)
It all starts when none of my games will play due to a possible issue with my graphics card. I look up "3D source game bug" and not many results pop up. I go on Microsoft's Qna areas and ask this question but to my surprise nothing they say would make sense. "Clean the pins of your graphics card, make sure you verify the games on Steam". I verified the games and they checked out as perfectly fine. I don't have access to my graphics card because this is a laptop, sadly not a tower.
Two months pass and my computer is already showing signs of stress, like it didn't want to live in a sense. It was three times slower than when I was on Windows 7 and it was unallocating areas of my main hard drive where I could make virtual hard drives.
Instantly I start looking up Linux distros and find Linux Mint. 17.3 was the current version at the time. I downloaded it and burned it onto a DVD-rom and rebooted my computer. I loaded into the disc and to my surprise it seemed almost like Windows 7 apart from the Linux part. I grab my external hard drive and partition it to hold the Linux distro and leave it plugged in incase Windows 10 does actually fail.
On December 19, a few months after Windows 10 had released. I start my laptop to try and continue my studies in video game development. But to my surprise, Windows 10 had finally crashed permanently. The screen flickered blue and black, and an error box saying Loginui.exe failed to start. I look at it for a solid minute as my computer had just committed suicide in a sense.
I reboot thinking it would fix the error but it didn't. I couldn't log in anymore.
I force shutdown the laptop and turn it back on putting it into safe mode.
To my surprise loginui.exe works and I sign in. I look at my desktop, the space wallpaper I always admired, the sound files, screen shots I had saved.
I go into file explorer and grab everything out of my default hard drive Windows was installed on. Nothing but 400gb got left behind and that was mainly garbage prototypes I had made and Windows itself. I formatted my external hard drive and placed everything on it. Escaping Windows 10 with around 100GB of useful data I looked at the final shutdown button I would look at.
I click it and try to boot into normal Windows 10. But it doesn't work. It flickers and the error pops up once more.
I force it to shutdown and insert the previous Linux Mint disc I made and format the default hard drive through Linux. I was done. 10 gave me a lot of shit. Java wouldn't work, my games has a functional UI but no screen popped up except a black abyss and it wouldn't even let me try to update my graphics card, apparently my AMD Radeon 5450 was up to date at the AMD Radeon 5000's.
I installed Linux Mint and thinking the games would actually play I open steam and Launch Half-Life 2 to check if Linux would be nicer to me than Windows 10 had been.
To my surprise the game ran. The scene from Highway 17 popped on screen and the UI was fully functional. But it was playing at 10-15fps rather than the usual 60-70fps. Keep look at my drivers and see my graphics card isn't in use. I do some research and it turns out I have a Hybrid Laptop.
Intel HD Graphics and an AMD Radeon 5450 and it was using the Intel and not the AMD. Months of testing and attempts of getting the games to work at high frame rates pass and the Damn thing still functions at a low terrible fps. Finally I give up. I ask my mom for a Windows 7 disc and she says we can't afford it. A few months pass and I finally get a Windows 7 installation disc through money I've saved up. Proudly I put it into my optical disc drive and install it to my main hard drive deleting Linux completely. I announced to all my friends my computer was back in working order and I install everything I needed, Steam, Skype, Blender, and Unity as well as all my games. I test Half-Life 2 and it's running exceptionally smoothly, I test Minecraft at max settings and it's working beautifully. The computer was functioning properly once again and my life as a developer started as I modeled things and blender, learned beginners C# and learned a lot of Batch. Today the computer still runs at a great speed and I warn others of what happened to me after I installed Windows 10 to my machine if they are thinking of switching from 7 or 8 on an older machine.
Truly the damage to my data cannot be undone. But the memory of the maintenance, work, tests, all are a memory of how Windows 10 ruined me and every night before the one year anniversary of Windows 10's release, I took out the battery of my laptop and unplugged it from the a.c. power, just so Windows 10 doesn't show it's DLLs, batch scripts, vbs scripts, anything on my computer. But now, after this has happened and I have recovered, I now only have a story to tell5 -
Me: Ok I'm not going to bother upgrading my PC, just going to use it and buy a whole new system later on...
PC: Yo' bro, remember when you had no clue at what you were doing and you didn't buy an 80 Plus certified PSU and used stock intel cooler? Yeah man you're going to need to replace both of these things, that'll be $280!
Of course this fucking happens, knew I should have waited till I actually knew what I was doing with PC hardware!5 -
Compiled Gentoo after ~5 days.
It's not ever yet though.
My kernel is now 7.3M, and it contains almost everything I need. Even my network drivers (intel) firmware is built-in.
It boots straight off UEFI (default BOOT/bootx64.efi), and
Managed to install X, Waylan (sway!)
Got dvorak programmer's keyboard defaulted.
df -h:
root 4.7G/14G (exact) used
boot 21M/127M (exact) used
var 701M/~5.5G used
AAAAAAAAAAAAAAAARRRRRRRRRRRRRGHHHHHHHHH
Was doing the installation from a Live CD (UEFI) during school hours, with my toughpad not working and no mouse with me. I feel bad for TAB.
I am, at this moment, still compiling...1 -
So apparently the Android emulator only works well on Intel processors
And there was me trying to be the good guy and buy AMD5 -
so, in latest news (source: trust me bro)
Intel cut off 15K employees from their workforce. But but but, they re-introduced free tea.
Win-Win, right?11 -
So continuing on my PC buying post, my friend found a cheaper, by $300, option but it's sort of a give and take. And not sure which one is the best. Plus AMD * still gives me a bad impression.

After some time, planning to install Linux again for personal use and some dev work at home. My current pc is getting too slow sometimes and it irritates me a lot.
My current pc 2gb RAM, Dual core Intel, 32 bit.
Main criteria, os should be fast, I can compromise on GUI, should be stable, should support my old configuration. I like to work on Java/Scala, python, js and sql. Eclipse will be there since I use it at work.
Short listed Ubuntu 16.04.2 LTS,
mint (huge confusion on gui),
Opensuse, elementary OS and arch. I had Ubuntu, mint for some time as secondary OS. Arch will be totally new world for me. I have tried few OS in USB boot but couldn't fix one.
Right now I am confused about which one to choose, since everything looks fine but I want the best choice based on my criteria.9 -
Recommend me a lightweight operating system for about 6 years old laptop with Intel Atom. 'nuff said I guess...21

Anything made by asus is a fucking garbage.
My first asus laptop was eee pc 701. It had only 2 gigabytes “ssd” which was just a flash drive using usb 2.0 inside. Doing this instead of using a proper sata ssd is like using bunch of rats glued to a frisbee instead of roomba vacuum. It displayed “intel 800mhz processor” in settings but this was only the processor’s name string, in fact it was only 640mhz single core. I still managed to install totally stripped version of windows xp to it and play some old games but overall it was horrible. It also heated up as hell.
My second asus laptop was infamous z99h. It had windows vista and was slow as hell right out of the box. Also BOTH hinges broke in just like six months. It was horrible as well. The screen itself broke in a year.
I also used asus rt-series router and it required a restart every day just to deliver some wifi. Don’t you dare tell me to “uPdATe fIrMwArE”, I pay money for the product and I expect it to work right outside the box.
Asus smartphones was also garbage.
So why have asus laptop if you can have a real laptop like MacBook or thinkpad? Why have asus phone if you can have a real smartphone like iPhone or pixel? Why have asus router if you can have ubiquiti?
Asus drivers suck, and all of asus software is just bloatware.10 -
I don't know what the devs at ProShow are smoking but I want some. Their product, specifically ProShow Production, is garbo. Don't get me wrong, the stuff is great for making slideshow with effects and stuff but good GOD.
+ If your image's name or the full path to the image contains anything that is not (I think) ASCII, the program will refuse to work with it.
+ If you're using non-English characters for eg. caption ("ẫ" for example) even on a Unicode font that supports that char, it will render a box. You know which box it is. You have to specifically use a font family to have it rendered correctly at the exchange of ugly-ass fonts that has been overused.
+ A majority of keyboard shortcuts are not supported while editing a slide (Ctrl + A, Ctrl + Z being my two favorite).
The best part? I'm forced to use this thing because of time constraints. I'd rather fry my puny 4GB RAM stick and crappy Intel HD Graphics 550 working with Premiere/After Effects than using ProShow. But nooope. ProShow. Fuck you. -
So, i have that assignment about docker stuff. nifty piece of software i must say.
anyways im installing docker software on windows bc im thinking if i have something that gives me at least the correct structure and some skeletal syntax i will have a faster grasp of the thing. expecting some sort of high level ide but end up instead with what looks like a blank window, with the only obvious choice being sign into some bullshit i dont need. but thats another story
my point is:
when installing the thing it prompted me to install WSL2. which i supposedly am not supposed to have because my cpu doesnt support intel virtualisation. but being impatient (thats why i came to look for an assisted solution), i pursued the installation.
lo and behold: i end up with a shell prompt at the root of a linux filesystem!
i ran 2 or 3 muscle-memory commands and closed the prompt, i was in docker stuff up to the neck.
later on, when i go back to my project, in a virtual machine its sluggish af and screams at me that amd-v is not supported because of something something nested pages (will look up later how that one works).
dont have time to explore it some more yet, and especially experiment or even barely look at this glorious mess because i have something barely working and no time to have it fail.
but this story definitely left me perplexed.
and also : you can run WSL2 on an fx83508 -
What machine(laptop) you rocking?
I own a very cheap hp product, looking for upgrade. There are so much option I don't think I can solo decide on this one.
I looked at Acer Aspire R 15 Convertible Laptop, 7th Gen Intel Core i5, 15.6" and HP Pavilion Laptop 15-cc5xx .
Suggest me some products please.(~$600)13 -
I just completed this heartfelt and sincere little cry for help on another ste but it wasn't verified because I'm not special enough to format it like a PAD, whatever that means. I cannot seem to simply burn music files anymore. I'm using a Samsung laptop Device name DESKTOP-AII2T2S

The music is a combination of commercially relased material as well as bootleg recorded material.
I am not looking for a "This is Why We Can No Longer Burn Our Music Files" Intro. All you need to tell me is the corporations that eat the world are protecting their copywrighted music and I must be up earlier and eat bettter breakkie than those individuals. That I can handle. Although I'm not a dev, I'm sure you can understand the feelling after you have worked for hours on attempting something, only to discover your effort has been in vain (much like my former relationships). Again, if you can give me any direction aside from hanging it up and attempting to find happeniness elsewhere, sock it to me. I deserve it. Thanks.
11 years ago when I used a Macbook putting together a playlist, inserting a blank CDR, and burning the file onto the CDR was very easy. I\'m am now faced with hurdles I sometimes scale, only to fall on my face.
I\'m not stupid, or uneducatated about flac, blah blah. I learnt it all myself. I\'m now using a windows operating system. Afew weeks ago I was able to burn what ever I pleased and it was OK.
Then one day, it just wouldn\'t do it. I was following no altered procedures. Since then it\'s been misery. I remember that ocenaudio once burned music files for me.
I don\'t know how to go about retrieving an instruction manual that will take me step by step as to how to do this.
You help would be appreciated.
Cheers,
Jonno
I've been lurking here since 2017 when my Macbook died. I've always enjoy the level of sanity and have attempted to add my jaded, distant and nihilistic spin on a few threads. It won't destroy me if I can't burn files anymore, I'll just go back on heavy tranques and change my name to Ben Zo. Dia Za P.een3 -
I was trying to set up my own "cloud" for iot experiments. I planned to use Intel Edison with mqtt broker (using mosca) and a node js app for providing API for mobiles and browser. And also to do other book keeping.
I spent the half day trying figure how to expose these servers to internet.
I configured ddns in noip.com and ddns settings configured to it in my router.
Port forwarded to the local server services I needed.
And then tested. Worked perfectly on any device in my router connected network. Tested on mobile network. Bam! It fucking doesn't work.
Then connected another router.
Double port forwarded. Again worked perfectly on router network. And failed on mobile.
Tested if ddns is right. Did nslookup it was fine as fuck.
Then disabled port forwarding. Did dmz. Nope. Nadda. No luck.
Then scratched my head so hard that I lost more already losing hairs.
Then remembered about router hardware firewall. Disabled it.
Tested
And there it didn't work.
My dreams shattered like a fucking deer hit by car on highway.
Didn't work.
Then I see the IP pointing to my router in nslookup. Its 172.20.xx.xx. Its a fucking private IP.
My Asshole ISP is running another private network behind firewall. Which I fucking can't port forward
Now I think how much of a noob and idiot I am. Fuck this shit. Fuck all of these shit.
I am going for SaaS option for mqtt broker.
(Or help me?)
Once again.
Asshole ISP.
Fuck your firewall.
(PS: I had test the next day. FML)2 -
Woo time for a Chromebook rant against Samsung!
So they just 'revised' the Chromebook plus (Currently using v1 to write this) and I was intrigued because they ditched the Samsung made ARM chips for an intel CPU.... Buuuuuuuuuut... It's a fucking celeron... Of all fucking things to put in a half thousand dollar laptop, at least an m3 would be useful. Then I find out they are ditching the full metal body, it's heavier, thicker, same 3GB of RAM, ditching the 3:2 aspect ratio (Fucking why?!) and the 'upgraded' keyboard doesn't even have back lighting...
Ugh, makes me want a pixel book more, double the price and a million times the performance and quality -.-5 -
Intel management engine pwned over USB
https://bleepingcomputer.com/news/...
With everyday that passes, this Intel ME rabbit hole just keeps getting deeper. -
It seems like they are going forward with the project…
Me like: I am ALREADY IN PAIN!
Sometimes I just stop…
and is just astounded of how things are, you know, managed. Leadership. What do they think about? At this corporation.
I mean. This going to hurt so, so much.
There is this movie made from a book that Tom Clancy wrote, The sum of all fears. In it Jack Ryan (Ben Affleck) needs to relay paramount intel (yes, i want to be an agent god damn it!) to POTUS. And I am like…
I AM JACK RYAN! I NEED TO GET THIS INFORMATION TO THE CEO. HE IS MAKING DECISIONS ON SOME VERY BAD INFORMATION.
But, I am far from actually getting even near to that individuals closest team.
So, things are what they are …and it it going to be boring and it will mean really hard work. For years. So, what to do… -
What I need to do today:
* terraform init
* terraform plan
* terraform apply
What I'm doing today:
* Rebuilding a docker container, because our outdated version of Terraform doesn't run on M1 Macs natively.
* Fighting with corporate IT man-in-the-middle SSL certs, because those aren't trusted inside the Docker container. These are now applied to all internet traffic, not just traffic destined to the VPN. Terraform doesn't like it, so it won't download any modules.
* Waiting for a blazing fast 1.5 Mbps connection rate when connected to the VPN.
* Learning I can no longer turn off the VPN, as it's a forced policy on my laptop.
Not sure if I'd be more productive today fighting these issues, or just waiting around for days (weeks?) for IT to mail me an Intel mac.6 -
You're all programmers, right? How do I get my Grandpa's ASUS (Intel Pentium, Windows 10) to run faster? Please please he asked me to help.4

Fucking Intel. Only allowing specific SFP transceivers on their x520-da2 card. I gotta load the firmware with a flag to be allowed to use my ubiquti transceivers.
And for some reason grub doesn’t let me use the “array” as the firmware said. So only one sfp port is active on boot. So I gotta find a clever way to get it to load properly. Maybe add a script to run at boot that does what I want. -
1997 Olivetti, 122 MHz Intel processor, 8MB RAM and 1GB HDD and Win 95. I mostly used software for children learning and games.
But my first “computer” was a shoebox with a keyboard drawn by hand on the cover and a screen on the bottom where I could change the “software” by swapping different drawings inside a transparent envelope.
All hardware and software made by me 😁 -
Fucking hate to explain basic shit to computer illiterate. Usually I don't mind, but right know I working on the project, want to automate one thing I need to do every morning, put two numbers to web page(I will explain details maybe in next rant). So I am only one who fix, buys computers, printer(for some problems I call for other repair man.). Generally speaking working as IT guy. Firm has like 50 computers, some of them has SCADA software. Some computers have Win 7, some win 8 and others win 10, can't upgrade those computers, not enough money(I can deal with this problem). And yes, computer buying is not the fastest, easiest thing too. Because is public firm, I need to do public buying(I don't know how to translate to english), and most of the time wins the lowest price, I am ok with that. But I can't on item specification write I want that model pc or it components. Example: I can't write I want intel processor, however I can write number of cores, frequency. But it's not that bad, usually i have template for all things I buy. One of the worst thing is this, our firm bought new bookkeeping software version, old version was using visual foxpro framework. Good thing I didn't initiate the purchase, because right know I would be jobless, not because I would be fired, but because our senior accountant would drive me crazy. In fact accountants drive me crazy, but I can handle it for now. As I wrote before our form has about 120 workers, major part of workers are old, like my parents age. (I am 28 btw. Mom is 55.). As you all know what happens if you say you work with computers. So our accountants are like 60 years old, got new program, don't know how to work with it, and they ask me how to do certain things. if I don't know how to I ask program's support, every question is like 90 Eur. So in short accountants expect I should know their work and how program works. If I try say something they don't like, they try to make my day hard. Next thing is our billing program. Man that worked before me done some payments import. And when I came everyone expect me to do that. Ok I did that because that people working with billing program would probably fuck it up. And I semi automated that, so I don't mind that much. Sometimes that program fucks up, like it happened yesterday, it send email invoices attachment without filename. Example: people got this attachment ".pdf"(no filename, only extension), And if you save it you need do OPEN WITH command and then select pdf reader or rename file (I don't know what easier). And surprise surprise our firm, customer support redirects all phone calls, emails to me. But I did explain to customer support what to say to people. Still they redirect it to me.
PS: This is my first job after school. I work as part time.
TL;DR Thinking my life, carrier choices. accountants are not the nicest people.8 -
Can someone suggest a new laptop for me?
- ~15 inches
- 12GB-16GB
- Ryzen 5 gen 1-2(or intel equivalent)
- No good videocard needed
I already have a good desktop to game, just need a laptop to code7 -
So i tried getting some games i play on windows to work with wine and steam.
After swearing and installing all the shitty dependencies it doesnt feel any good. And worst of all i knew not all games are going to work though.
As i wanted a good and portable setup i thought alright maybe this is going to be a good use case for docker. But its a pure nightmare to get everything running fine. At the end i gave up that shit.
So dual boot is still the only way for me to be able to play games without hacks and an unreasonable amount of work.
Using gpu passthrough to kvm is a pure nightmare too. I mean what the hack, the best way to use it is to have two fcking video cards?! And yeah the integrated intel shit graphics are no option.
I mean why the fuck is it even necessary to perform dirty hacks because the most game publishers dont give a fuck about linux.
Seriously it isnt that fucking hard! And Proton is a good step for some games, but only as a temporarily solution, that only exists because of shitty game publishers.
It is horrible, its 2020 and i still cant get fully independent from windows, no matter how hard i try.
Is it that fucking hard to add builds for linux to their shitty games?!14 -
I want to build a small personal linux server from an old PC

sata hard drives
I was going to go for free nas but I read that I'll need to connect the PC to the router via a lan cable, I dont have a router and very costly for me rn to purchase one.
I also feel like it will end in tears but I'll try
pass or nah?16 -
Fuuu!!!
I'm currently on elementary.
I have two monitors, one plugged to my Rx 560 and GPU and the other to onboard graphics.
Despite this my main monitor is rendered on the Intel inbuilt GPU and I have stuttery gui on my primary monitor.
(My second one is an old monitor and I can't find VGA to dvi converters, on Windows it just works so I haven't had an issue)
Please help me guys !1 -
Question for the dev community about best laptops. I'm coming from developing on frankly outrageous desktop machines for the past two years (8700K with 32 gigs of memory and Intel Optane SSDs). I'm starting a new job soon where I'll need to buy a laptop to use at work for portability reasons. Company is giving me money to pay for it, budget is $2,000. What's a fairly portable laptop that isn't going to feel really slow switching over from crazy desktop builds like that?3

I open Photoshop, I open an image, I start editing colors. I think to myself "I need to change units to pixels instead of inches". I open the "Preferences - Units" menu. I approach the mouse and click on the selection box for units.... My screens go crazy suddenly and I get a BSOD...
The computer reboots, refuses to repair, complains it can't write on the disk. I launch UBCD, start TestDisk, it tells me my MFT and the mirror MFT are both completely messed up and the partition contents as well... Wow wow... What the...?!
Complete reinstall.
Thank you Intel GFX system driver. -
Learning system development. Period. Heck, I'm still looking for resources that don't cost hundreds of dollars, require me to open-source everything I want to make, require that I read a 4000-page Intel manual, and/or ask that I be in a graduate program or have a degree that I am still earning.3

*tried to install latest intel GPU driver on a notebook*
Intel: this driver isn't design for your system please contact your device manufacturer
*Check again the compatibility list ... The CPU is present*
Me: okay, let's try this one, using display driver uninstaller to clean the old driver, reboot and launch the new one.
Intel: This program will install the new component graphic driver Intel®
Me: Well ... I guess I win this time ?
Still don't know why the previous one seems to block any installation of I don't manually clean it.
My previous version doesn't seems to be specific to anything ...1 -

I have been working on a long time, low progress project of mine that keeps on giving and giving.
Let's begin like two years ago where I dipped my toes into "more then gigabit" networking thanks to a Linus Techtips video about infiniband.
I had the dream of booting my Workstation from my NAS, a so called diskless setup.
Well, since I run FreeNAS on my Nas , a very nice Freebsd based Nas OS, everything's gonna be good.
In the beginning, there was no infiniband support.
Turns out, you don't need it, since the mellanox CX2 nics can do ETH too.
Yay.
Just took me a few weeks of anger.
So, to be able to boot something over the network, you need firmware that finds the bookable stuff and loads it.
That protocol and firmware is called PXE.
PXE needs a DHCP telling it what to do, and what is where and etc.
Freenas here I come! Installing dnsmasq on the actual freenas install turned out to be not that great of an idea because freenas thinks of itself as being an "appliance" that you don't fiddle with. So things work, until you update/ upgrade when everything will basically be wiped, except what you have done through the ui.
Ok. So I gona use a jail, a container like thing for that.
Everything is great, jail has internet, everything Installs fine, what could go wrong?
Dnsmasq can launch and work, but not as dhcp server. Some thing about permissions.
Turns out, jails have permission like things.
A few days of head scratching later, it has ALL the permissions.
Dnsmasq still can't work as DHCP server though, why you ask?
Because it needs a specific kernelmodule that isn't contained in the jail. Since jails are kind of like a docker container, they run on the same OS kernel, who does not have this module, I'd need to patch the freenas, which is an appliance, so fuck that.
Like a year later, freenas has finally added good VM support, so why not make a VM for the dhcpserver?
Well, about a year ago, I didn't know that the virtual Intel nic is a fucken unstable piece of garbage, crashing nearly any OS at some point.
So that was it for a while again.
Now to the last few weeks.
Finally dnsmasq is running in a freebsd VM with a good and working configuration which is rather simple, if those tutorial fuckers out there would explain shit instead of just telling you to copy, paste and replace X.
Now back to the PXE side.
I'm using iPXE because I have no clue how to boot anything over tftp so iSCSi it is, since that is what I can relate too.
The idea behind iscsi is to fake a SCSI disk over the network. Attached devices appear as if they are actually directly connected to the machine instead of over the network.
iPXE gets a lease from the server, can connect to it, everything is fucken great. Finally.
Except that if it "sanBoots" the iscsi drive, it can't find anything to boot.
Well fuck.
If I attach a Linux live USB over iscsi, it boots, finds grub, and crashes because the live iso isn't configured for network-boot.
But it boots.
So what's so different?
Well iPXE is booted in legacy mode, where as the content of the target is windows 10 in efi mode.
Ffff.
Ok. Can I get iPXE to boot in EFI mode?
Well yes, after like 3 days fiddling with it.
But it only finds the onboard Intel nic instead of the new Mellanox CX3 cards, and can't even connect to the target....
Sooo, I guess my options are as follows.
Either, get PXE efi to work on the network cards directly, its called flexboot and might be able to since I just found some firmware options for that.
Or give up on efi and install windows in legacy mode.
Which isn't that easy when it has to end up on a drive on my nas. -
Well, it's me again from yesterday, so i did a minimal debian install and i think i did what the debian site said regarding the graphic drivers for ati but here's the deal:
xrandr --listproviders only shows the intel provider, the dedicates amd gpu [RX 550] is not shown. (Also on doing lspci it is shown as a Display controller instead of vga adapter.)
+ the laptop heats a lot too
Any idea regarding what should i do? Or maybe where do i get help?
Off topic question: What is the difference between vga adapter and display controller??
