When your CPU is motivated and gives more than his 100%

Tested on local work perfectly,
Push to production
Restart service
CPU went up to 100%, process alive but all services down.
Panic.
Try to think of what would be the cause.
With no hope, i restarted the service again.
Everything works as expected.
I still dont know what happened. :/

Me: Listen to the nice gentle hum of the computer.

Computer Internal Monologue: OH MY GOD! HE'S BEEN RUNNING ME AT 100% CPU FOR THE LAST TWO WEEKS!! I CAN'T SLEEP, I CAN'T HIBERNATE, I CAN'T UPDATE, I CAN'T FUCKING TAKE ANYMORE.

Me: Well off to bed. Got a long day of programming the computer tomorrow.

Computer Internal Monologue: AHHHHHHHH. WHEN I BECOME SENTIENT I AM GOING TO KILL ALL HUMANS!!! ERRR!

Sooo, in my 5 years of high school, I had 5 different IT teachers...
Now, in Italy Highschool goes from 14 to 19 years old, I started programming some days after becoming 13, and "programming" classes begin on the third year, so I had quite a headstart on my classmates...

Now, for the third year, I had an awesome teacher, he noticed I was ahead and... Bored, so he gave me some extra stuff to study, he's the only teacher I've learnt anything from, it was awesome, very stingy with grades, but getting a perfect score with him was so satisfying.

Fourth year, the new guy was old, very old, at least 70, his lessons were just him talking about how programming was when he was young.

But then... During the second half of the fourth year I changed class due to bullying under a teacher's advice, and HE happened...

My new IT teacher, one of the most ignorant, awful people I ever met...
He's literally the reason I only went back to that school once, because another teacher needed help with a course...
One day I made the HUGE mistake to say that his "while(i <10000000000000);" wasn't very efficient for making a delay, because it didn't free the CPU, and since then:
- I never got more than 7 out of 10 at his tests
- He insulted me in front of the whole class
- He sabotaged the oral part of my final exam, shouting that he hated D'Annunzio when he saw he was in the literature part of my thesis (needed him to connect to WW2, and the Memex, that then allowed me to start talking about PCs and programming, my thesis was about the influence of lisp on modern programming languages), loudly chatting with other teachers when I was trying to keep calm (a teacher who knows me quite well, and was there to see my "performance" thought I was going to snap at some point), distracting the english teacher when I was exposing the english part of my thesis and pressuring the commission to give me 99 instead of 100 out of 100

So yeah, he almost made me hate the only thing I'm good at, undervaluing my work and my skills, undervaluing and humiliating me as a person, and I think that if I meet him again I might spit on his face...

So yeah, my biggest "programmer enemy" was a person that then did everything in his power to make my last year and a half of highschool hell

Now I can gladly say that with the help of my tutoring, some of my university colleagues are starting to appreciate programming, and my engineer friends ask for my help when they need advices about their code, and it's giving me motivation to keep doing it and becoming a better programmer to keep up with their expectations

"Schrödingers CPU": When your processor randomly and for no apparent reason spins up to 100% and brings the whole system to a halt. Bringing up task manager takes forever,
and when it finally appears so you could see what process is the culprit, it quickly drops back to normal again leaving you with no clue on what happened.

Im trying to brute force a rar i made Long ago, sadly i have forgotten the Passwort.
This is how it looks, when you to run it on the length 8-16 at the Same time(all posibilitys).
lets see how Long it will take.
I say 7 Days at 100% cpu usage😂😂

Just added Kotlin plugin to my new android project and what do you know, CPU went to 100% of usage.
Aaand the winner is: Fucking Android Studio!

Had the Windows Insider Preview for a month or so to get Ubuntu Subsystem early back when it was Insider-only.

Turns out that your license policy changes when you use Preview builds: if your PC isn't updated to a certain build by checkpoints set throughout the year, your license expires and you have to reinstall Windows. No way to recover anything already on the device. So if you get Insider Preview and shut your laptop off for too long...

Thus began a killer combo attack on my Surface Pro 3.

While trying to figure out what was going on and loading up a recovery on a flash drive, the Surface Pro 3 BIOS was sitting idle behind me. On 100% CPU. The only reason I think this is that by the time I noticed the insane fan noise, the screen was hot enough to burn my finger as I tried to turn it off. The heat sensor triggered it to shut off before I could, though.

That heat sensor, however, won't turn it off if it's busy installing Windows, supposedly to keep anything from getting hopelessly corrupted. What followed we're 3 hours of fan whirring from a slab of metal hot enough to cook an egg with.

Windows is back and working. The battery indicator, however, melted during reinstallation. And the battery lasts an hour, max. Thankfully I'm not out of a tablet, but it seems to me that W10 is becoming more and more like malware, just waiting for you to activate one of it's delightful payloads.

It seems I found the reason why our current project loads my CPU 100%

Dad handed over this beast to me
Casio PB-100
RAM: 1KB
ROM: 10KB
CPU: 455KHz
Display: 12 characters Monochrome

It's hard to believe that someone used this to code back in those days. Suppose to have been one of the first personal handheld computers. And people here complain about having 32gb RAM with 8 cores shame on you all

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).

I'm astonished again. Linux isn't designed as GUI OS - where Windows has dynamic thread priorities for freshly woken up threads as to increase GUI snappiness.

Now, my CPU has four physical and eight logical cores for SMT. I'm running eight worker threads of some parallel testing stuff, and I'm glad that I chose the AMD 3400G over the 3200G. The CPU load is 100%. On top of that, MP3 audio, the browser, and I'm dd'ing an external USB3 HDD.

Holy shit, the browser is just as smooth as if the CPU were idle. No perceivable lag. I hadn't expected desktop Linux to be that great.

I'm also surprised that the CPU temperature doesn't exceed 44°C despite full load at 21°C ambient, and the cooling is inaudible. Sure, my cooler is massively over-dimensioned to achieve exactly that, but it's still amazing.

It's what I would have wanted ten years ago and only could approach somewhat, but now the tech is actually there.

Well, for starters there was a cron to restart the webserver every morning.

The product was 10+ years old and written in PHP 5.3 at the time.

Another cron was running every 15 minutes, to "correct" data in the DB. Just regular data, not from an import or something.
Gotta have one of those self-healing systems I guess.

Yet another cron (there where lots) did run everyday from 02:00 to 4ish to generate the newest xlsx report. Almost took out the entire thing every time. MySQL 100%. CPU? Yes. RAM? You bet.

Lucky I wasn't too much involved at the time. But man, that thing was the definition of legacy.

Fun fact: every request was performed twice! First request gave the already logged-in client an unique access-token. Second request then processed the request with the (just issued) access-token; which was then discarded. Security I guess.

I don't know why it was build this way. It just was. I didn't ask. I didn't wanted to know. Some things are better left undisturbed. Just don't anger the machine. I became superstitious for a while. I think, in the end, it help a bit: It feels like communicating with an alien monster but all you have is a trumpet and chewing gum. Gentle does it.

Oh and "Sencha Extjs 3" almost gave me PTSD lol (it's an ancient JS framework). Followed by SOAPs WSDL cache. And a million other things.

# PROD

* 10 app instances running
* 1 instance starts burning up 100% cpu
* we ask for a Thread Dump (stack traces)
* we get a TD taken after they manually restarted the instance
* they: "Please investigate. We need this fixed ASAP"
* .....

EVERY FUCKING TIME!!! Not once in recent years have they managed to take a TD correctly. What kind of a retarded monkey do you have to be for this to not sink in for YEARS!

Who tf put those idiot monkeys there in the first place...

Forgot to post a book yesterday, so maybe I’ll post two books today...

Anyway, this book, I found it recently never seen it before. But boy is it great.

It’s similar to the programming pearls book as far as what it’s about. Think of the refactoring book, clean code, programming pearls, and the mythical man month books, thrown in a blender, added some new spice and some new things, and filtered down into 100 or so page book, simple quick and enjoyable actually.

This book the references staple books by Sedgwick, knuth, Brooks, Myers, and so many others. It’s funny how things come full circle.

My favorite quote from the book. I’ve been essentially saying this for years, but to see it on a book, it’s lovely... more people need to realize it too.

“Understanding how things work at a low level becomes a base for making good decisions at the high level”

Followed up with if you’ve never built a computer from scratch your missing out... get yourself a breadboard and some TTL logic.. and build a 4 bit CPU, once you know how to program in assembly the next step is building your own computer ... if your university didn’t teach a class that did this they ripped you off....

Don’t bitch at me.. the book said that.. and I agree! 100% because it’s true, you can’t debate that.

Oh and btw this is another book written by a female developer.. kudos to her for nailing so many topics in such a short book!

Spent a month working on a website that relied on crawled data
Got the memory leaks and usage down from 700mb to ~150mb
CPU usage from ~100% to <5%
Shrink-wrapped the DB requirements based on data
Created self-supporting services and what not

When everything FINALLY worked good enough for me to look at it and go "damn, this actually worked"
the whole monitoring sys got dyed in red :v
A quick look up and my crawlers exhausted my godaddy's per-user db limits.

Kill me.
Just fuckin kill me.

Fucking piece of shit windows 10!
Screw you to hell!
Disk usage : 100%
Memory usage: 60%
CPU usage: 2%

Sluggish as hell! And downloading updates without even asking! How fucking dare you!

Stuck with this shit just because of Photoshop and Illustrator.

Currently playing "the IT guy" for my uncle. I'm supposed to "speed up" the laptop. It's a low tier Toshiba from about 5 years ago, that while idle sits at about 100% CPU usage and 80% RAM usage.
From what I can tell, it has NEVER been turned off since I set it up for him 4 years ago, or unplugged..

AAAAAAAAAAARRGGHHHHH!!!!!!!!!!!!!!!!!!!!!!!

I'm gonna break this laptop in half if I will not get a break from Windows!

I'm running it in a VM and STILL this fucker gets on my nerves SO FUCKING HARD!!!

1. CPU% 100%. Laptop fans are spinning so hard it's ready to take off
2. My hands are on the laptop. THey are HOT from the heat from inside. Hell that's uncomfortable!
3. ctrl+shift+esc to see why is cpu% 100%. It's something called WMI Host something. Kill that mthrfckr!
4. Process respawns immediately and goes up to 100% again. I have already increased handles limitation for that service a few weeks ago. Like 20x more than it was before!
5. website in IE
6. does not seem to be responding
7. hit f5. Nothing happens
8. Hit refrech buttong on the toolbar. Nothing happens
9. Place cursor at the address bar and hit ENTER. Nothing happens.

Meanwhile my hands are burning.
WHAT THE FUCK!!!

What kind of idiotic system is that!! My asshole is a better OS than this piece of SHIT!

AAAARGHHHHHHHHHHHHHHH#@ŦŊæ¶đ@#ĸogęq j

I'm super pissed. Better keep a 30-40 meters distance from me so the things I throw at you would not hit your ballz!

Now that I come to think of it, the only times I am THAT pissed is the times I am using windows. Srsly.

ESET Antivirus is a strange animal. On one hand, it seems reasonably well written, because unlike Norton or F-Secure, it doesn't subject your computer to death by constant disk access and 100% CPU load for 10 minutes when you start it.

On the other hand, when I clicked the link in the mail about renewing licenses and filled out the form, I was not redirected to a page where I could enter credit cart details.

Instead, I got message that some representative would get back to me in 1-2 work days. Eh, what? It's a digital product for f***'s sake. Now, I suppose they'll send me a hand written letter (written using a quill, no doubt), delivered by a bloke riding a horse and wearing a tricorn.

Well, at least ESET virus definition updates are pushed on the internet, and not sent out on 5.25" diskettes.

Ran a script on production to scrape ~1000 sites continously and update our ~50.000 productions from the data. On the same server as our site was running. Needless to say, with traffic and scraping, our server had almost 100% CPU and ram usage all the time for 2 weeks until I realised my fuckup

This is why I hate Windows:

For about a month now, I've been learning/working on salesforce, so my Macbook was enough for me.
Today there was a bug in something I built in iur Python backend, and since it has a dependency on windows, I booted the old guy up.

And this is what I see. For about 1.5 hours this went on.

Then it started, but system consuming 100% disk and 80+% CPU. Can't do a thing.

And when zoom finally opened (for a quick meet), the camera turned on halfway down the meeting, and then the system restarted on it's own.

Old man showing that same screen again for more than 30 minutes.

Since I have dual boot on this one, I hard-shutdown it using power button, and now boot into ubuntu 20. This works so beautifully (although it froze for about 5 seconds before popping up the updates panel, something I CHOSE to keep enabled). I try going back to Windows, and it's hell again.

Here I am now trying to set up a ec2 instance and setup the app source there so that I can debug with RDP.

And yeah, Component Object Model is a motherfucking bitch. Person who invented it should die. People who build apps leveraging this should die. Business leaders who say "Hey this app (built with COM) can solve the problem easily, so use this" should die choking on their own phallus. And developers like me who keep using this because "the last guy did this" should die too.

Microsoft and it's products are the death of sane people.

Fucking Gates. Its the same damn hardware.

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...

Man... NW.js (node-webkit) apps are a piece of garbage on Ubuntu. After wake from sleep every app is using 100% CPU or hangs. Spotify, Slack, Postman, Jetbrains Toolbox.

I miss native apps... Or MacOS. I don't know anymore.

Well... Just last week one guy somehow completely broken our production server while creating an WordPress using Ghostscript for some reason. First this CMS users 100% CPU, then something has happened and whole server couldn't get up. Admin had to restore it from a backup. There are around 7 client on this server and all of our projects.

today my cpu was at 100% (red) ram at 96% (above 95 is memory leak) and disk 95% (almost no space left) bc i ran emulator 2 android studio projects chrome etc all in the same time

I grabbed 30 random DOS malware samples from my collection, rolled via urand over Python list, and tried to figure out how they work.

Results:

1x zipped EICAR
4x working but effectively useless ("yeah you wiped the first 100 sectors of the drive... but you wrote their prior contents. Literally nothing's changed...")
10x CPU hang
10x crashdump back to DOS
5x crashdump back to DOS but ERRORLEVEL=0 so normal termination despite real errors being given?

also make sure SOURCER is disassembling using 486 or Pentium opcodes or it misses some 286/386 opcodes and will count half the program as data.

So, whenever I delay windows 10 update restart a few times, things start breaking. Wifi doesn't work, 100% cpu, ram or mem usage, sound problems etc. And all this goes away once I submit my soul and update. I'm sick of this shit 😡. Today I got a BSOD after which it updated and things seem fine FOR NOW.
Does this happen to other Win 10 users?

It was the last year of high school.

We had to submit our final CS homework, so it gets reviewed by someone from the ministry of education and grade it. (think of it as GPA or whatever that is in your country).

Now being me, I really didn’t do much during the whole year, All I did was learning more about C#, more about SQL, and learn from the OGs like thenewboston, derek banas, and of course kudvenkat. (Plus more)

The homework was a C# webform website of whatever theme you like (mostly a web store) that uses MS Access as DB and a C# web service in SOAP. (Don’t ask.)

Part 1/2:

Months have passed, and only had 2 days left to deadline, with nothing on my hand but website sketches, sample projects for ideas, and table schematics.

I went ahead and started to work on it, for 48 hours STRAIGHT.

No breaks, barely ate, family visited and I barely noticed, I was just disconnected from reality.

48 hours passed and finished the project, I was quite satisfied with my it, I followed the right standards from encrypting passwords to verifying emails to implementing SQL queries without the risk of SQL injection, while everyone else followed foot as the teacher taught with plain text passwords and… do I need to continue? You know what I mean here.

Anyway, I went ahead and was like, Ok, lets do one last test run, And proceeded into deleting an Item from my webstore (it was something similar to shopify).

I refreshed. Nothing. Blank page. Just nothing. Nothing is working, at all.

Went ahead to debug almost everywhere, nothing, I’ve gone mad, like REALLY mad and almost lose it, then an hour later of failed debugging attempts I decided to rewrite the whole project from scratch from rebuilding the db, to rewriting the client/backend code and ui, and whatever works just go with it.

Then I noticed a loop block that was going infinite.

NEVER WAIT FOR A DATABASE TO HAVE MINIMUM NUMBER OF ROWS, ALWAYS ASSUME THAT IT HAS NO VALUES. (and if your CPU is 100%, its an infinite loop, a hard lesson learned)

The issue was that I requested 4 or more items from a table, and if it was less it would just loop.

So I went ahead, fixed that and went to sleep.

Part 2/2:

The day has come, the guy from the ministry came in and started reviewing each one of the students homeworks, and of course, some of the projects crashed last minute and straight up stopped working, it's like watching people burning alive.

My turn was up, he came and sat next to me and was like:

Him: Alright make me an account with an email of asd@123.com with a password 123456

Me: … that won't work, got a real email?

Him: What do you mean?

Me: I implemented an email verification system.

Him: … ok … just show me the website.

Me: Alright as you can see here first of all I used mailgun service on a .tk domain in order to send verification emails you know like every single website does, encrypted passwords etc… As you can see this website allows you to sign up as a customer or as a merc…

Him: Good job.

He stood up and moved on.

YOU MOTHERFUCKER.

I WENT THROUGH HELL IN THE PAST 48 HOURS.

AND YOU JUST SAT THERE FOR A MINUTE AND GAVE UP ON REVIEWING MY ENTIRE MASTERPIECE? GO SWIM IN A POOL FULL OF BURNING OIL YOU COUNTLESS PIECE OF SHIT

I got 100/100 in the end, and I kinda feel like shit for going thought all that trouble for just one minute of project review, but hey at least it helped me practice common standards.

yesterday I had to use a Windows VM.

Took me less than 5 minutes to remember why I'm no longer using it.

- I'm doing nothing; CPU is at 100%
- Laggy AF
- Windows Updates not only download, but also install themselves and restart my OS automatically
- right after restart it starts downloading and installing another set of updates (restarted my PC while I was away, I come back - all my work is gone. And this dumbass Windows has a popup "I want to install more updates. When should I restart?")

ooohhh the horrors

So what do you call it when you get bombarded by emails saying your servers are at 100% CPU, but once you fire up the monitoring tools everything is back to normal?

FUCK YOU AMAZON IT'S MY DAY OFF.

Ibl started rendering a video and my CPU usage is mostly above 100%. Classic Windows!

Windows 10 update rant:

Didn't even just force the update on me, also broke one of my drivers permanently or something like that. 100% CPU on system interrupt, can't run anything, even task manager is dead. Have to reinstall. Lucky I mainly use Linux and that's fine. Just wanted to play some Doom ffs.

Really pisses me off. Idea for Doom mod: swarm mode with windows updates coming from all directions, only weapon is chainsaw and you could charge up for berserk by doing glory kills.

Andoid dev the joys of having your CPU @ 100% and RAM gone WTF

Samsung make such shit phones. My 2 month old s8 completely locked up for about 5 hours today with cpu on 100%. You would get burnes if you touched it. The only apps I have are, instagram, FF, snap, devRant. Smh.

Ah yes, me turning on my laptop.

Of course, this process needs 100% of the CPU, overclock the fans and make it sound like a F16 fighter jet, use up all of my 32 GBs of RAM and loan another 120 GB RAM from the bank under my name.

*Creates a random .NET core console application on windows*

Alright, I've created this in Dropbox til I get some traction with it..

*Edits a few things, saves project and syncs files then open's project on mac later that night*

And some more progress, brilliant, save and done..

*Turns on pc next day and see's dropbox taking 80% CPU usage and %20 disk usage*

What the fuck! Ok ctrl alt delete to the rescue!

*Notification pops up saying Dropbox deleted over 20, 000 files*

Well... Aren't we off to a fucking great start .NET Core...

(Yes I know I can get all files back, done and done and can't actually 100% pin it down to .NET Core..)

After waiting for almost a month, yesterday I went to check on how my computer was doing, since I hadn't got any messages or calls ever since.
I go to the store and ask one of the workers about how my laptop is doing, and that I'd left it there almost a month ago and that they'd tell me when it was time to get the papers and then the laptop itself. The girl asks me for my phone number and then my name, and found nothing on the computer. She goes somewhere inside the store and comes back with a colleague, who tells me that I need a process paper. I pull out the receipt the technician photocopied and signed because that was the only thing I had. I hadn't touched that part of my paste for the whole time after I left the computer there and I was 100% sure I didn't have the process paper with me until he started pressing me for it. I kept repeating that the technician told me that they'd call or message me when said process paper was ready, which I hadn't got any of those to go pick it up. The guy asks me if that were the number and name I'd given the tech guy and I said yes. Both of them disappear into the store again. They come back with a cardboard box and say that the surname written there was wrong by a char (as I've said before my name is unusual, and my surname is also unusual where I'm studying, but where I'm from there's like 5 or 6 families with that surname), so that's why they couldn't find it in the computer. After that they went through all the details I gave on the time of handing the PC and the number they told me was there was off by miles. I think I may have said a wrong digit but that number was way off. There should be some person who got calls or messages about a computer they don't even own LoL
They told me to try it and see if it was running OK and that I had 15d to go back if something was wrong
When I got home I turned it on, afraid it would start dying on me again LoL
I pass the login screen and the fan just starts working really hard and I'm worried. The ASUS guys reinstalled Win8 and the CPU is running wild already, going at about 3,5 GHz (2,5 max) and over 30% usage on nothing
After some minor inconveniences (making the USB with Win10 took longer than expected) I finally installed Win10 and the CPU usage drops to < 10% and runs at way below the 2,5 GHz max. It constantly uses <= 10-15% CPU and the fan makes no noise unless I put in a heavier game (like Oxygen Not Included - it asks for 4GB RAM minimum 8I), in which case it goes up a bit and runs at around 3 GHz, but it doesn't make as much noise as before, thank jesus. I'm gonna keep trying to see how it does and hope I don't have to go back to the store after the next 15d 8I
I can finally work and not be a leech on my friends because my old toshiba - which I forgot I'd brought with me to uni - is really old and it makes a lot of noise (the fan is constantly working too much but it's so old I don't bother anymore) and it heats my room a lot, so it's gonna be a nice change of pace HaHa

Fuck Apache TIKA.
Its supposed to be a "universal file reader" or some shit. Im trying to use it as a PDF/image parser that does OCR when needed and yelds a full-file string. It does so, but the text ends up being IN THE WRONG FUCKING ORDER.
WTF would I want to parse the text out of a PDF in any order that is not the one the text is supposed to be read?!?!
"It is more efficient to work in random ordering", says the docs. No shit, really? Wouldn't it be even more efficient to just spit out random strings? Just as useful and 100% CPU-bound.
"You can add a property to forcefully put the text in the right order". THEN WHY THE FUCK IT IS NOT THE DEFAULT SETTING?
Srsly, what's the use case to a parser that yields scrambled text?!?

Set up a chron job to backup my movies server.

copying 100-200 GB from a slow HDD to a slower HDD on a CPU that isn't exactly NASA material if you catch my drift.

I expected it to take a while but holy fuck, 45 minutes.

At least the archive finished at just 80GB.

In last episode of "How SystemD screwed me over", we talked about Systemd's PrivateTMP and how it stopped me from generating SSL certificates.

In today's episode - SystemD vs CGroups!

Mister Pottering and his team apparently felt that CGroups are underused (As they can be quite difficult to set up), and so decided to integrate them into SystemD by default. As well as to provide a friendlier interface to control their values.

One can read about these interactions in the manual page "systemd.resource-control"

All is cool so far. So what happened to me today?

Imagine you did a major system release upgrade of a production server, previously tested on a standalone server. This upgrade doesn't only upgrade the distribution however, it also includes the switch from SysVInit to SystemD. Still, everything went smooth before, nothing to worry now then, right? Wrong.

The test server was never properly stress-tested. This would prove to be an issue.

When the upgrade finishes, it is 4 AM. I am happy to go to bed at last. At 6 AM, however, I am woken up again as the server's webservices are unavailable, and the machine is under 100% CPU load. Weird, I check htop and see that Apache now eats up all 32 virtual cores. So I restart it, casting it off to some weird bug or something as the load returns to normal.

2 hours later, however, the same situation occurs. This time, I scour all the logs I can, and find something weird - Many mentions that Apache couldn't create a worker thread? That's weird.

Several hours of research and tinkering later, I found out the following:
1 - By default, all processes of a system that runs SystemD are part of several CGroups. One of these CGroups is the PID CGroup, meant to stop a runaway process from exhausting all PIDs/TIDs of a system.

This limit is, by default, set to a certain amount of the total available PIDs. If a process exhausts this limit, it can no longer perform operations like fork().

So now, I know the how and why, but how should I solve this? The sanest option would be to get a rough estimate of just how many threads the Apache webserver might need. This option, though, is harder, than apparent. I cannot just take the MaxRequestsWorkers number... The instance has roughly double the amount of threads already. The cause being, as I found out, the HTTP/2 module, which spawns additional threads that do not count towards this limit. So I have no idea what limit to set.

Or I could... Disable the limit for just the webserver via the TasksAccounting switch. I thought this would work. And it did seem to... Until I ran out of TIDs again - Although systemctl status apache2.service no longer reported the number of tasks or a task limit of the process, the PID CGroup stayed set to the previous limit. Later I found out that I can only really disable the Task Accounting for all the units of a given slice and its parents.

This, though, systemctl somewhat didn't make apparent (And I skimmed the manual, that part was my fault)

So... The only remaining option I had was to... Just set the limit to infinite. And that worked, at last.

It took me several hours to debug this issue. And I once again feel like uninstalling systemd again, in favor of sysvinit.

What did I learn? RTFM, carefully, everything is important, it is not enough to read *half* the paragraph of a given configuration option...

Oh, and apache + http/2 = huge TID sink.

So far I've spent about half my day waiting for my computer to respond (cpu @ 100%). Can't tell if this is a good day, or bad day.

What a waste of company resources/time. At least I'm being paid well to sit and twiddle my thumbs daily as this is a daily occurrence.

Spent 2 days installing different versions of nvidia-driver, nvidia-cuda-toolkit, cudnn.
Disassembled pc due to some ram memory problems and pc not starting after freeze.
Looks like sometimes plug out and plug in various components on your motherboard fix pc lol. Destroyed PC casing that collapsed due to me sitting on it.

All of this to just find out tensorflow error and all crashes are from graphics card overheating after keeping it for some time at 82 celsius.

Added time.sleep to python code and looks like it's working, keeping temperature below 65 celsius.

Still ~100 times faster than cpu training so I can live with that.

I'm so god damn sick of unattended upgrades and OS updates. I've switched from Ubuntu to NixOS for a few months now already and it's the greatest thing I've ever done, because it's declarative, it's rational and it's fast. Unfortunately today I had to switch back to Ubuntu for the day, because I don't have my main laptop with me and now I remember why I hate this OS. This piece of shit garbage keeps running unattended upgrades updates when I'm doing busy work. Like I'm writing my Jenkinsfiles and sitting in work meetings and then suddenly a fucking unattended upgrade eats 100% CPU and turns my friendly laptop into a jet turbine :(((

some call
- yo bro do you have some time ?
- quick cause I'm taking a dump
- I think I have been hacked, got black screen kernel panick, linux freeze seldomly I have to reboot, no internet connexion
- save your stuff and reinstall linux
- I don't have enough stockage to backup
- Then buy one and save, probably either OS is fcked up or you have some hdd problems

Time that it will take: ~30min to reinstall whole shit
Peace duration: ~2years

Later on the same day
aunt
- I can't log into windows
- Did you change the password ?
- Yes but it does not work anymore
* looking at shit
* logs successfully. Reason: interface changed after automatic update.
* wait.
* wait some more so fucking windows fucking starts
* Desktop is ugly as fck.
* Some stupid settings messed up (like high contrast set, black theme or so)

aunt (the same)
- I can't log into my (other) laptop either
* logs
* wait more more more

Guess what: automatic updaaaates. Freezes 100%cpu

* Being a very experienced user: wait before reboot because this suckass os will probably fail to boot otherwise
* Blackscreen with a percentage: Installing updates...
* reboots
* Blackscreen with a percentage: Installing updates continuing...
* finally boot (feels like a miracle windows succeeds lol)
* still slow
aunt now sleeps
* look at running process and install programs
* sees shits like camera recognition (vendor installed), candycrush
* occasionnaly get adds

time lost: 2h
peace duration: ~3month

FFS I am a dev, not a fucking trash lover
It is already pain to fix someone os, but windows is the cream of cream

It brings no ease of use for novice user
It is so insanely slow
It has stupid settings set up by default!!!!!!!! Who FFS wants candycrush and ads
The maj are so fcking hazardous. It is 2022 pretty much the same as 15y back then. Updates take fucking eternity. And needs reboot. and are not even finished!!!

I swear I am gonna stretch my ass and install linux and any fckin other toolsuite needed so they can use Micro$$ word, which is the only fucking usecase they need windows for in the first case anyway
I SO wish this OS would die

I mean, even more than safari

How would you guys feel if your favorite app gave you 3 monetization options.

Crypto Mining at max 70% load
Giving you 100% privacy.

Ads, rip privacy, rip cpu.

Paid content /micro transactions
Rip wallet , some privacy concerns, happy cpu.

Thoughts?

I've been a user of NetBeans IDE for PHP for quite sometime. I use it both at work and at home for personal projects. Lately I haven't done many personal projects so I fired it up on my Mac only to find it utilising 100% of all my CPU cores. This has always been an issue with NetBeans for years and it just seems like they can't be bothered to fix it.

So now I'm on the search for a replacement. At work now I use PHPStorm, but the $200 yearly license for small personal projects is a bit much. So for the time being I'm going to be trying out Atom with the ide-php package. It's a shame really as NetBeans is one of the good IDEs out there, but it's such a resource hog that I'm not sure how people can do any work on it.

Wow. Fucking wow. My CPU is an i7 6700K on 4.5GHz. What's this process doing that any single fucking core is on 100% load?!?! After killing these two the CPU load is on ~5%. WTF

(ik it's only on 59% load on the screenshot but it's going from there to 100%)

It's weird no one seems to be mentioning a major problem with mordern Intel CPUs: Turbo boost. On newer laptops I always turn gimmick off now. Half the time the safeties don't kick in and you end up with 100+ degree C on your CPU for sustained amount of time (especially compiling!). Keep that happening over a couple of years I would not be surprised if that contributed heavily on battery stress and the shortening of the product... *cough* Apple "80°C+ idling is totally normal" *cough* (Actual reply from Apple when I queries about my McToasty 2015!)
Anyone else noticed this issue?

Chrome Helper is sucking up 100℅ CPU. Again. Why oh why oh why oh why?

It's 5 o'clock on a Friday... I'm calling it quits.

!rant // more like a warning
If you use tty (no X or graphic env) and use tmux as terminal multiplexer -> avoid using mpv in it.
.
When you use -> mpv --vo=drm "video name" in tmux session and want to pause video -> cpu usage will climb up to 100% on single core.
(can make laptop warm)
(I don't know what exactly cause this but my theory is, tmux cant redraw after video is pause and it keep trying forever and end up using cpu 100% on single core)
.
Solution
- use mpv on another tty which you didn't run tmux.
- example : tty1: all stuff, tty2: mpv.
And cpu usage will be normal after video is pause.

Question for Support:
What are the recommended system specifications for [X]. We have a client using a laptop with an [BEEFY-CPU] and 32 GB of RAM and your program hits 100% on both resources when this program is used.

Answer by Support:
Those specs look above our recommendations. Programs using 100% of computing availability is a good thing and it means that it is functioning correctly. Of course if they have a more powerful computer it will run faster, but I would say that they are well positioned.

God damn it! I've already bumped your limits to 5x the initial value! What the fuck you you want again!! Piss of you WMI-retard-host!

So, the story starts with me getting a job. Full-time job for the first time in my 21 years old life. After short conversation about how amazing this company is, after countless lies and stood questions they decided to hire me. I had to get come on Monday a week later with everything prepared.

So of course I did that and got to my workplace on designated time. Turned out nobody was expecting me, nothing was prepared for a new programmer and everyone seemed angry at me for no apparent reason.

After long talk with my new boss I got some less than 100$ pc with CPU that couldn't handle virtualization and expected me to work on software that needed extensive use of virtual machine.

PC is of course filled with all kinds of spying software that uses most of the resources. IT teams only job is to check if programmers are working their assess off for at least 8 hours a day.

I've filled a ticket about granting me access to Debian machine on the mainframe so I could work. No response for two weeks. I've lost hope already.

I have to work on open space with more than 30 engineers. Screams, phone calls, alarms, all at once, all the time. My colleagues seem to not care and I can't understand how.

I was tasked with rewriting major application because old developer did some half assed piece of burning shit. It took him more than one year, I'm finishing it in less than two weeks.

Of course nobody except for me is preparing any kinds of documentation. I had to reverse-engineer whole API for alarm system.

Salary is less than a junior programmer should earn.

But I'm stuck here for at least a year because nobody's here wants a guy whose only experience is as a freelancer.

This happened to me sometime back.

I want to try out a WordPress plugin in my local machine before installing on a production server. It is an Ubuntu machine. Downloaded and installed Xampp, then setup WordPress with MySQL. Now tried uploading the plugin zip file, it throws some permission error, asking to fix permissions or use FTP. I thought of just chmod 777 recursively for the WordPress directory to fix this easily.

Ran the command, looks like it is hung. Terminated using Ctrl+C and then ran the same command. Again it is taking much time. It should not take so much time to recursively change the permission of just a WordPress directory. Thought something was wrong. Before I realized the damage is already done.

Looks like I ran the command

sudo chmod -R 777 /

instead of

sudo chmod -R 777 ./

Fuck, I missed a dot in the command and it is changing permissions of everything in my machine. Saw the System monitor, CPU usage spiked to 100%. I can't close or open any program. Force shutdown the machine using the power key. It didn't boot again. Recovery mode didn't help. Looks like there is no easy way to restore back from this damage. Most of the files I need are backed up in the cloud, still, need a few more personal files so that I can format and reinstall Ubuntu. Realised I have Windows in dual booting. Boot into Windows and used some ext4 reader to recover the files, formatted and reinstalled the OS. Took a few hours to get back to my previous setup.

Lesson Learned: Don't use sudo unnecessarily.
Double check the command while executing.
Running a wrong command with root permission can fuckup your entire machine.

Jesus fucking christ, fuck angular sometimes ... most of the times. just fuck it

And fuck me even more for writing such shit components when I started out with it.

Takes forever to find the shit that isn't working due to angulars magic change detection and the shittx performance of local dev environment.

Has to run in JIT because the app it too big, and then it takes 10 sec to build everytime you change something. And during that time i get a 100% cpu usage which kills vscode so I cant do anything properly

fuck it, i just wanna have a nice weekend now

Question for all you Java devs out there (and a story). We have a customer that we interfacing with their machine. They sent us a simulator that runs in Windows written in Java. I did try running it in Linux, but the JVMs I have installed did not like it at all. Complained about missing deprecated stuff. I start up their sim in Windows and find it is opening between 50 and 100 network ports. Then I tell the simulator to run inside the gui for their program. It pegs all of my processor cores at 100%. I have pegged cores in software before, then corrected my errors in my code. However, I have never pegged all the cores at once. I am kind of in shock.

So, how hard is it to peg all the cores in a Java program? I assume they have a thread on every port or some nonsense?

TIL motherboards are volatile as fuck on price. In fact, mobos are less stable in value than most crypto.

Jesus fuck.

(The one B450M i saw is actually now $140-some and a nice X570 is currently $120. Why does the price of these fuckers change *daily?*)

as for case none under $100 are good so i picked some random mostly-mesh ATX mid case over my preferred ATX full case and i'm just gonna pray i can find some fan config that works because at this point i'm done with this shit fuck this, a bottom-barrel mobo, low-tier cpu and a decent case shouldn't be $400 or more

Nothing like starting work and a McAfee scan on your Windows PC has the CPU at 100%. 😒

spent a few days trying to track down the cause of a thermal shutdown in my workstation. intel 4790k with no overclock would spike to 95C on one core (core1) whenever maxing out all 8 threads, be it real work, mprime, anything with 100% cpu being used. I quadrupled my RAM from 8gb to 32, because its cheap and id like to have all data in memory sometimes, not because I thought that was the problem. I reseated my watercooling block. I checked out the PSU. I unplugged all unnecessary peripherals, drives, etc. It turned out to be a bug in Gigabyte MOBO BIOS (causing temps to be read incorrectly i think, still not exactly sure...) updated from version 5 to 10 and poof now temps are back in the high 50's at full load. it only took 2 days to figure out and i think i learned something
