Yes Linus Torvalds is an asshole and the world is better because of it.
In short Linus's acid takes on code quality over developer fee fee's might be one of the things that has made the Linux kernel and the GNU/Linux project such a long lasting open source success and in my opinion the risk of him falling for all this "let's be nice and non offensive" bs trend may impact negatively on code quality.
Being an asshole has it's downsides and it's not always the best response, I'll give you that, but personally I think most of us who are viewed as assholes are seen like that because we put quality over convenience, facts before feelings and dedication over mediocrity; it is not because we hate you, it's because we measure ourselves with the same stick.
It depends on one's character, but when you've been toughened up because of bullying(I don't doubt many devs have been since being a nerd has never been hip) or life in general, you learn to stop whining & pick yourself up and you expect everyone to be competitive and competent as you are and it gets frustrating to manage people who don't fulfill your expectations.
Pros: You get shit done and you do it well.
Cons: People won't like you and you don't tolerate failure (much less mediocrity).
Yes Linus is an asshole, my coach was an asshole, some of my best teacher's have been assholes, I had friends who were assholes, heck I'm an asshole!
But I thank them because they made me better than I was, just as people have thanked me for being the right amount of asshole.
A warm thank you and fuck you Linus, keep being the asshole we need.36 -
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.

Linux developers threaten to pull the kill switch...talking about giving people the finger this week...
If you have been following the nerd news these last weeks you may have heard about Linus leaving Linux (temporarily) and implementing the new CoC (pronounced cock) code of conduct thanks to the constant pressure of the ABC of inclusion (LGBTQLMNOP+ groups).
This new code of conduct aims, believe it or not, to change the predominantly white, straight, and male face of programming and it also seems to "mitigate the consequences of dogmatic meritocracy".
That's right, are you white, male, straight or otherwise pull yourself out of the mud? Yes, YOU are part of the problem (also racist, sexist and probably islamophobic).
Bullshit I know, these SJW privileged upper class assholes are pushing for these changes to inspire witch-hunts against good devs like Larry Garfield (cause: sexual fetishes) and give themselves more power over the free speech of people.
Ironic if you ask me because I haven't seen anything similar for oil rigging which is riddled with cis males (but ain't as comfy).
But not everything is lost and that's why this hasn't been a mouth foaming rant because boy I'm proud to know there are devs with balls out there; It seems there's a little detail with the GPL2 license and all those unjustly banned by the new stupid racist ass CoC can withdraw the license to their contributions crippling the Linux kernel project.
I'm not happy that GNU/Linux is being threatened like so, but it was about time we put a stop to this, your politics, skin color, religion and ideas should not matter when developing code, what matters is the code you produce.
Want to politicize our repos and kick out devs just because they don't think the way you do? Let's see how long you last without the contributions of the "deplorables"; let us see how many good contributions your new "diverse", PC stack do (other than changing master/slave or other terms).
My guess...as I've said earlier, everything these PC busybodies touch, if unchecked, crumbles to dust. (EA 😉)

26 years ago Linus Torvalds sent out this message to the comp.os.minx newsgroup.
Hello everybody out there using minix -
I’m doing a (free) operating system (just a hobby, won’t be big and
professional like gnu) for 386(486) AT clones. This has been brewing
since april, and is starting to get ready. I’d like any feedback on
things people like/dislike in minix, as my OS resembles it somewhat
(same physical layout of the file-system (due to practical reasons)
among other things).
I’ve currently ported bash(1.08) and gcc(1.40), and things seem to work.
This implies that I’ll get something practical within a few months, and
I’d like to know what features most people would want. Any suggestions
are welcome, but I won’t promise I’ll implement them :-)
- Linus
PS. Yes — it’s free of any minix code, and it has a multi-threaded fs.
It is NOT protable (uses 386 task switching etc), and it probably never
will support anything other than AT-harddisks, as that’s all I have :-(.
Fast forward to today and Linux has more than 12 000 contributors from over 1300 companies that contribute to the Linux kernel.
The Linux Foundation released a fairly detailed progress report, including an infographic which I was tempted to include here but you can view it in it’s original context here.
While you’re over there, remember you can be a sponsor of the Linux Foundation too.
Happy Birthday Linux and a giant thanks to not only Linus but every single one of the contributors that have taken part of it over the years.5 -
Apparently this guy's pull request claims that his code is "very fast" (Official Linux github repository). I can't stop laughing looking at the file changes xD

The Linux Kernel, not just because of the end product. I find it's organizational structure and size (both in code and contributors) inspirational.
Firefox. Even if you don't use it as your main browser, the sheer amount of work Mozilla has contributed to the world is amazing.
OpenTTD. I liked the original game, and 25 years after release some devs are still actively maintaining an open source clone with support for mods.
Git. Without it, it would not just be harder working on your own source code, it would also be harder to try out other people's projects.
FZF is possibly my favorite command line tool.
Kitty has recently become my favorite terminal.
My favorite thing open source has brought forth though is a certain mindset, which in the last decade can be felt most heavily in the fact that:
1. Scientific papers with accompanying GitHub urls, especially when it comes to AI. Cutting edge research is one git clone away.
2. There are so many open hardware projects. From raspberry pi to 3d printers to laser cutters, being a "maker" suddenly became a mainstream hobby.12 -
So yet another follow up rant on the Linux job hunting! (yes hello this is @linuxxx).
Got send a list with questions (for candidate screening) and was literally mentally preparing to answer all the questions (I expected shit like Linux commands, kernel stuff etc etc).
Then I saw the questions. Mother of god.
1. Have you ever worked with a Linux distro and if yes, which one(s)?
😶. Uhm I expected some more difficult stuff.
2. Have you ever worked with a hosting interface like CPanel etc?
😶😶. Alright I should adjust my view on the difficulty level of these questions.
And so it went on and on. I think I make a pretty good chance 😆.
I'll hear more at Monday and if all is good then I will get an interview through Skype with their American office!10 -
"Arch Linux is actually not that difficult".
I ssh'ed into my home server yesterday.
I was greeted by a message from an ext3 disk about needing fsck. Fine, "I haven't been in here for a while, might as well do some maintenance". fsck /dev/sda6, let's go!
This nicely "repaired" the sshd service (i.e. cleared the sectors), I cursed at myself for pressing enter at "repair (y)" right before the connection broke.
So I connected a display and keyboard... ok so let's just pacman -Sy sshd or whatever. We can do this! Just check the wiki, shouldn't be that hard!
Wait... pacman has not run since 2010? WAIT IT'S ACTUAL UPTIME IS 9 YEARS??? I guess we know why I'm a DB admin and not devops...
Hmm all the mirrors give timeouts? Oh. The i686 processor architecture isn't even supported anymore...?
4 hours, 11 glasses of cognac, 73 Arch32 wiki/forum pages, 2 attempts at compiling glibc, and 4 kernel panics later: "I think I'll buy a new server".16 -
fork() can fail: this is important
Ah, fork(). The way processes make more processes. Well, one of them, anyway. It seems I have another story to tell about it.
It can fail. Got that? Are you taking this seriously? You should. fork can fail. Just like malloc, it can fail. Neither of them fail often, but when they do, you can't just ignore it. You have to do something intelligent about it.
People seem to know that fork will return 0 if you're the child and some positive number if you're the parent -- that number is the child's pid. They sock this number away and then use it later.
Guess what happens when you don't test for failure? Yep, that's right, you probably treat "-1" (fork's error result) as a pid.
That's the beginning of the pain. The true pain comes later when it's time to send a signal. Maybe you want to shut down a child process.
Do you kill(pid, signal)? Maybe you do kill(pid, 9).
Do you know what happens when pid is -1? You really should. It's Important. Yes, with a capital I.
...
...
...
Here, I'll paste from the kill(2) man page on my Linux box.
If pid equals -1, then sig is sent to every process for which the calling process has permission to send signals, except for process 1 (init), ...
See that? Killing "pid -1" is equivalent to massacring every other process you are permitted to signal. If you're root, that's probably everything. You live and init lives, but that's it. Everything else is gone gone gone.
Do you have code which manages processes? Have you ever found a machine totally dead except for the text console getty/login (which are respawned by init, naturally) and the process manager? Did you blame the oomkiller in the kernel?
It might not be the guilty party here. Go see if you killed -1.
Unix: just enough potholes and bear traps to keep an entire valley going.

Seriously, just how exponentially fucked did this world just become.
I'm pretty sure that this post's format would be more tailored towards devrant.com (well, hereby). But I wanted to vent about it, here, now.
A copy of this post is available at https://facebook.com/irc.condor/....
Just the other day the EU Parliament accepted that widely disapproved copyright directive - article 11 and 13. Despite direct lobbying on our end. And by whom? Not by young, competent parties like the Pirates. No, instead the old fucks from the conservative party had their say, driven by nothing but incompetence and lobbying from label companies.
Then the whole ordeal with the Master/slave issue in Python started. Again met with significant outrage - and again approved while completely ignoring the voices of everyone else. I even ended up making a fork for it at https://github.com/toloveru/cpython. Please star it to show your support for the cause. It is made in response to a denied revert at https://github.com/python/cpython/....
And then we had the issue of Linus Torvalds leaving the Linux project. The single most important person when it comes to Linux.. and he left, just because he admits to be an asshole - something which apparently needs to be changed?! Dude, be a fucking asshole! That's what made the Linux kernel great in the first place!!! Yet even you give in to those SJW cunts?!!
AND THEN... If Linus' disappearance wasn't enough already, core developer at the LLVM project Rafael Avila de Espindola leaves the project as well, because of an influx of SJW's and political correctness.
It started with feminism in the past century. Now it's superiority and pink-/blue-haired warriors going for OUR SUPERIORITY AND UNIQUENESS and being offended by whatever they can possibly get offended with. Fucking cunts they are. You heard that right. FUCKING CUNTS!!! Because yeah, in my house I swear like that. Anyone who doesn't like that can fuck right off.
But what good does my criticism towards all this still serve.. nothing, does it. Those live wires that I've avoided touching for so long.. they suddenly don't feel all that repulsive anymore. Thanks society!23 -
Whoever designed UEFI, FUCK YOU!! Giving the OS control over every fucking thing in the hardware instead of letting the BIOS do that separately, WHO IN THEIR RIGHT FUCKING MIND THOUGHT THAT THAT WAS A GOOD IDEA?!!
And same goes to fucking you Microsoft! How difficult is it to do a fucking ACPI shutdown and do it properly?! How fucking difficult is it to not make the fans spin like jet engines because why the fuck not?! And yes the fucking PC is dust-free and bloat-free so I don't want to see any fucking Wintard comment that.
You know where else I saw the inability to power down? In Linux 4.20-rc2. A kernel that is within active development, and rc2 at that!! A kernel branch that's designed to be unstable, for testing purposes. Meanwhile the stable branch of MS Windows does the same. Also designed to be unstable because fuck QA?! Filthy fucking motherfuckers!!27 -
--- Linux wants some hugs, and everyone gives a hug about it! ---
After the CoC controversy revolving around the Linux Kernel project, a change introduced by the CoC is being put into practice:
Jarkko Sakkinen, from Intel, started replacing words comments containing "fuck" with their "hug" variant. This means comments such as
/* master list of VME vectors -- don't fuck with this */
might look a bit different in the future:
/* master list of VME vectors -- don't hug with this */
People that oppose this change criticize that the comments will make much less sense to people that aren't fluent in English yet. They also do not like the redundant censoring - the actual meaning is still implied, just no longer included as clear text. It might also cause misunderstandings to people working with the code.
Those supporting this change, aside from jokingly mentioning that this change will save one character per f-word comment, note that this can give the Linux Kernel project a more positive feeling with anyone who works with the code, with "fuck" mostly associated with bad feelings, while "hug" is indeed mostly going to call positive feelings in our subconscious minds.
Who doesn't like a good hug? :)
What is your opinion on this rather controversial topic? Feel free to let us know in the comments, as we are very interested in your stances and arguments on this!

Preface: This client, let's call him dickhead, is running a successful brick-and-mortar based business in one of the top cities of the world. He is highly qualified in a non-IT field.
Rant: This son of a shitbag things he knows everything because he can search on Google, has a degree, owns an expensive business, and of course has money. Does not listen to my suggestions on which framework to use, how to integrate stuff, etc. because he thinks he is the fucking father of Linus Torvalds, and Linus built Linux kernel out of his super-intelligent sperm.
But that titbag can't understand the simple fact that he has spent the last 2 fucking years building stupid websites which he thought from his brain located alongside his balls. None of those websites are in the condition to launch, forget making a difference. Primary reason being using wrong frameworks for wrong purpose, but his half-assed brain can't understand this.6 -

So this year I had a subject at university called "Linux internal architecture", and for the last assignment I had to write a kernel module and interact with it with a separate program written in C.
Once I had finished and tested the driver, I went on to write the other program, which was supposed to use system calls to read and write data to the module. While debugging this program (~500 lines of code) I reached the level of frustration where you just start printing absurd messages everywhere in your code to see what's wrong. So for example instead of printing "This error happened in this function", my error messages were more like "Fuck this fucking function it doesn't fucking work".
Guess who forgot to delete all those messages before sending the code to the teacher...
Also, if a specific mode is selected, the program enters a while(1) that, apart from doing what it's expected to do, also creates a file in the user's home directory called something like 'motherfucker' and appends the words 'fuck this shit' to it. INFINITELY.
I really really hope this teacher doesn't try to run the program in his own computer, or he's in for a big surprise.8 -
Found this on discord.
Could be copypasta but I decided to share it anyway.
"I use Linux as my operating system," I state proudly to the unkempt, bearded man. He swivels around in his desk chair with a devilish gleam in his eyes, ready to mansplain with extreme precision. "Actually", he says with a grin, "Linux is just the kernel. You use GNU+Linux!' I don't miss a beat and reply with a smirk, "I use Alpine, a distro that doesn't include the GNU coreutils, or any other GNU code. It's Linux, but it's not GNU+Linux."
The smile quickly drops from the man's face. His body begins convulsing and he foams at the mouth and drops to the floor with a sickly thud. As he writhes around he screams "I-IT WAS COMPILED WITH GCC! THAT MEANS IT'S STILL GNU!" Coolly, I reply "If windows was compiled with gcc, would that make it GNU?" I interrupt his response with "-and work is being made on the kernel to make it more compiler-agnostic. Even you were correct, you wont be for long."
With a sickly wheeze, the last of the man's life is ejected from his body. He lies on the floor, cold and limp. I've womansplained him to death.14 -
I'd just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use.
Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.20 -
I remember when my professor in Linux Kernel Programming told us this is a programmers bible, everyone has this one right ?12

Working with a client...the resident """sysadmin""" hasn't actually been a sysadmin since the early 90s, the last OS he _actually_ managed was SunOS 5 or something. I can't remember what he said. He hasn't kept up AT ALL with modern technologies/terminologies. He's convinced SELinux is a security hardened kernel. We've explained to him several times that it's not but he sees Linux and thinks Linux 1.0 from the 90s. It's downright embarrassing.
Now this would all be well if I didn't have to interface with him often, but the client WILL NOT give me access to their systems. So I have to go through him to get anything done. Which is over webex. So I get to watch this guy type (and mess up) basic commands over and over (he isn't aware of tab completion of any of the bash features that are super useful). So I'm telling him what to type and the delay is always just enough for him to get too far in the command to back out, so its like SSH-over-incompetence with a 500ms ping. It's truly infuriating.
Every once in a while he'll get frustrated enough to hand me control of his webex session, which isn't as painful but once again the delay is bad enough it's still a pain.
Best part is that he looks EXACTLY like Milton from Office Space. So thats one plus to this whole situation!3 -
How to from hapiness 100 to 0 in seven simple steps:
1. Buy a new 2018 gaming laptop..
2. Install Linux on it for work..
3. Figure out your touchpad is not supported even by latest kernel rc..
4. Spend four days going through forums, bugzillas and overflows while messing around with recompiling kernel, drivers, configs and 3rd party libraries..
5. Lie down and pray someone will add support for your device in kernel in near future..

(I wrote most of this as a comment in reply about Microsoft buying GitHub on another rant but decided to move it here because it is rant worthy. Also, no, I'm not a Microsoft employee nor do I have any Microsoft stock).
Microsoft buying GitHub makes sense. They contribute more to the open source community on GitHub than any other company. (Side note, they also contribute/have contributed to the Linux Kernel).
Steve Ballmer isn't running the show anymore. Because of that, we have awesome things like:
* Visual Studio Code - Completely free and powerful light weight IDE for coding in just about any script or language. This IDE is also open source, hosted on GitHub. It can be installed on Win/Mac/Linux.
* Visual Studio Community Edition: fully featured flagship IDE free for solo developers and students, can be installed on Win/Mac.
* Fully featured Sql Server running in a Docker container.
* .Net Core, which can be compiled to native binaries of Windows, MacOS AND Linux. You can't even do that with Java, you have to first have the JVM installed in order to run any kind of Java code on any of those operating systems. .Net Core is also an absolutely beautiful framework with so many features at your disposal.
...and more.
Yes, they've done bonehead things in the past but who/which company hasn't. Yes, they have Cortana. Yes, they force Bing on you when searching with Cortana (does anyone actually regularly use Cortana? Or Bing?). Yes, their operating system costs money. Yes, their malware-style Upgrade-to-Windows-10 tactics were evil and they admitted such. Yes, they brought ads and other unfortunate things to Skype. I'd be lying if I said I wasn't concerned about that Skype bit translating over into GitHub. BUT, the fact that so many of their employees use GitHub daily means they are dogfooding the platform, which is a positive thing.
Despite the flaws, from the perspective of a software engineer they really should be given a lot of credit for all these new directions they are moving in now. They directly aim to help and contribute to the developer community. Plus, Windows 10 is finally getting a dark theme! haha.
I think Microsoft buying GitHub makes a lot of sense. Of course do what you want about it, feel how you want about it, but casting the same ol' shade at them for anything they do seems a bit like automatic reflex more than anything else.
I'm bracing myself for the impending wave of angry hornets from the nest I just kicked. In all seriousness though, I welcome discussion on the topic even if you feel differently than I do. I'm not saying there's no reason to dislike them, just saying there are lots of new reasons to hate them less and/or appreciate what they are doing now.19 -

GNU? Linux? Ha! How ancient! Everyone uses systemd-coreutils and systemd-kernel. Nobody needs those useless old programs. In fact, systemd is so good that even Microsoft recently released their own systemd distro, and adopted the motto: “We Really Do Love Open Source This Time”. To show their love for open source, they’ve released the source for Snipping Tool under a BSD license.
systemd is super lightweight! My system uses around 600 gigs of RAM, whereas Windows uses upwards of a terabyte! I currently use the systemd-gnome desktop environment. I used to use KDE Plasma 18, but it didn’t integrate well with the rest of my operating system. systemd-braininterface doesn’t work very well with my Nvidia graphics card, so I use systemd-x11 like a hipster.
I’ve had no regrets switching to systemd. I feel bad for those BSD nerds. What a laughing stock, sticking to POSIX. Nobody writes POSIX programs anymore.
I wonder what lies in the future for systemd... I hope they fix systemd-oomd.13 -
I've got a confession to make.
A while ago I refurbished this old laptop for someone, and ended up installing Bodhi on it. While I was installing it however, I did have some wicked thoughts..
What if I could ensure that the system remains up-to-date by running an updater script in a daily cron job? That may cause the system to go unstable, but at least it'd be up-to-date. Windows Update for Linux.
What if I could ensure that the system remains protected from malware by periodically logging into it and checking up, and siphoning out potential malware code? The network proximity that's required for direct communication could be achieved by offering them free access to one of my VPN servers, in the name of security or something like that. Permanent remote access, in the name of security. I'm not sure if Windows has this.
What if I could ensure that the system remains in good integrity by disabling the user from accessing root privileges, and having them ask me when they want to install a piece of software? That'd make the system quite secure, with the only penetration surface now being kernel exploits. But it'd significantly limit what my target user could do with their own machine.
At the end I ended up discarding all of these thoughts, because it'd be too much work to implement and maintain, and it'd be really non-ethical. I felt filthy from even thinking about these things. But the advantages of something like this - especially automated updates, which are a real issue on my servers where I tend to forget to apply them within a couple of weeks - can't just be disregarded. Perhaps Microsoft is on to something?11 -
Me a while ago talking to a recruiter over the phone. This was for a C++ dev position.
(R)ecruiter : So except for the development things, we are looking for someone who has experience configuration linux. Do you have any experience with that?
(M)e : Sure, I use Linux all the time. What do you mean.
R : Well, Just using Linux isn't enough for this position, you need to have experience in configuration Linux.
M : Well. I can't answer your question if you don't specify what you mean. Do you mean that I need to be able to install my own packages? Set up my dev environment? Bash scripting? Being able to configure my bash profile to have good aliases? Use Linux to develop software? Because I can do all of these.
M : Or do you need someone who can write Kernel modules for the OS, because I don't have any experience in that but would like to learn.
R : Oh, I don't really know what it means. But the paper says that you need to have experience configuration Linux. So what would you say your experience with that is?
Me internally : JESUS CHRIST I JUST TOLD YOU WHAT I KNOW AND WHAT I DON'T KNOW HOW ARE YOU GOING TO ASSESS ME CORRECTLY.
Me 😎 : I use Arch and you have to set it up completely from the ground by your self so I know everything there is to know.
Basically every question was like this with the recruiter. I got further in the process but quit because the workplace looked like it would drain my soul when I got interviewed by the employees of the company.
Jesus Christ though, some recruiters could be replaced by an automated phone system.17 -
This rant is particularly directed at web designers, front-end developers. If you match that, please do take a few minutes to read it, and read it once again.
Web 2.0. It's something that I hate. Particularly because the directive amongst webdesigners seems to be "client has plenty of resources anyway, and if they don't, they'll buy more anyway". I'd like to debunk that with an analogy that I've been thinking about for a while.
I've got one server in my home, with 8GB of RAM, 4 cores and ~4TB of storage. On it I'm running Proxmox, which is currently using about 4GB of RAM for about a dozen VM's and LXC containers. The VM's take the most RAM by far, while the LXC's are just glorified chroots (which nonetheless I find very intriguing due to their ability to run unprivileged). Average LXC takes just 60MB RAM, the amount for an init, the shell and the service(s) running in this LXC. Just like a chroot, but better.
On that host I expect to be able to run about 20-30 guests at this rate. On 4 cores and 8GB RAM. More extensive migration to LXC will improve this number over time. However, I'd like to go further. Once I've been able to build a Linux which was just a kernel and busybox, backed by the musl C library. The thing consumed only 13MB of RAM, which was a VM with its whole 13MB of RAM consumption being dedicated entirely to the kernel. I could probably optimize it further with modularization, but at the time I didn't due to its experimental nature. On a chroot, the kernel of the host is used, meaning that said setup in a chroot would border near the kB's of RAM consumption. The busybox shell would be its most important RAM consumer, which is negligible.
I don't want to settle with 20-30 VM's. I want to settle with hundreds or even thousands of LXC's on 8GB of RAM, as I've seen first-hand with my own builds that it's possible. That's something that's very important in webdesign. Browsers aren't all that different. More often than not, your website will share its resources with about 50-100 other tabs, because users forget to close their old tabs, are power users, looking things up on Stack Overflow, or whatever. Therefore that 8GB of RAM now reduces itself to about 80MB only. And then you've got modern web browsers which allocate their own process for each tab (at a certain amount, it seems to be limited at about 20-30 processes, but still).. and all of its memory required to render yours is duplicated into your designated 80MB. Let's say that 10MB is available for the website at most. This is a very liberal amount for a webserver to deal with per request, so let's stick with that, although in reality it'd probably be less.
10MB, the available RAM for the website you're trying to show. Of course, the total RAM of the user is comparatively huge, but your own chunk is much smaller than that. Optimization is key. Does your website really need that amount? In third-world countries where the internet bandwidth is still in the order of kB/s, 10MB is *very* liberal. Back in 2014 when I got into technology and webdesign, there was this rule of thumb that 7 seconds is usually when visitors click away. That'd translate into.. let's say, 10kB/s for third-world countries? 7 seconds makes that 70kB of available network bandwidth.
Web 2.0, taking 30+ seconds to load a web page, even on a broadband connection? Totally ridiculous. Make your website as fast as it can be, after all you're playing along with 50-100 other tabs. The faster, the better. The more lightweight, the better. If at all possible, please pursue this goal and make the Web a better place. Efficiency matters.9 -

An alternative kernel to Linux that is being rewritten in C++.35 -
I love Linux, but its community can be so full of incompetent assholes..
Just now I asked in Freenode ##linux how to get the process ID of my current running process in bash. I got my answer - it's a shell built-in called "$$".
Then people start to nitpick some more - why do you need it? How is that different from an exit? - to which my response was.. well I know the whole idea behind exit codes, and I'd use it whenever possible, in all defined behavior that allows my program to terminate itself whenever it can. This pidfile however would be used to exit itself and provide diagnostic information whenever the program enters undefined behavior - a segfault in C language. Scenarios in which I don't have full control over the script's behavior anymore, such as the system entering an unworkable state where the system stalled, still got some binaries in RAM but the rootfs got unwritable, such as now - very helpfully, thanks HP! - when my laptop likely overheated and shat itself. I issued sudo reboot into it, but even that wouldn't issue properly anymore due to the /sbin/poweroff binary becoming inaccessible too. I had to issue a hard power cycle.. one of the few times in which I'm thankful to HP for actually causing shit like this, lol.
Point is, that undefined behavior is what I'm trying to mitigate against. I certainly can't let any files other than diagnostics remain in nonvolatile storage like that, especially when their state should be predictable in order to ensure good operation (like files expressing whether the script is already running or not, i.e. lock files).
Back to that IRC chat. Aside from the answer, I got ridicule from people who probably don't even know how to properly compile a kernel. Ubuntu users, overconfident scum. Sometimes I feel like I should ask questions in channels like #archlinux only, where such incompetency is ridiculed on its own.13 -
DISCLAIMER: UNPOPULAR OPINION
I'm tired of the Linux community, they effectively discourage me of taking part in any discussion online
I'm currently making Windows-only soft, some game stuff, some legacy DirectX stuff you got it.
Everytime I go online, this shitty pattern happens, when I stumble upon a problem in project I don't know how to fix and I ask for help
These are responses
- HA, HA, WINDOWS BAD, HA, HA, GET REAL SYSTEM
- In Linux, we can do X too. I mean it has 4x less functionality and way shittier UX and is even harder to implement but it can probably work on too Linux, so it's better, yes, just move to Linux
- btw you didn't like Linux before? Try this distro man, it's better <links random distro>
Is there anything valuable in the Linux community? I feel like these people don't like Linux anyway, they just hate Windows. Every opinion, tip is always opinion based. Anyone who works on internals knows how much better and how well thought is Windows kernel compared to Linux kernel. Also, if someone unironically uses Linux distro on desktop PC then he's a masochist because desktop Linux is dieing. So many distros ceased work only this year.
Is it a good tool for servers and docker containers? I don't have my head stuck up my ass to admit that yes, it's much better than Windows here.
This community got me stressed right now, I fear that when I go to bathroom or open my microwave there's gonna be a Linux distro recommendation there

*gets countless amounts of shit with Windows because of my "nonstandard use"*
WanBLowS fanbois: "Cheap hardware!! Hardware error!! Unstable drivers!!! Can't be anything else, this OS is rock solid."
I really wish that I had your ignorance. I know when I see a shitty OS in front of me. And mind you, it actually ran Linux a while back.. just that I couldn't use my Nvidia GPU in it and had to compile a kernel with all of that crap excluded to make it work decently.. fuck Nvidia. And you know what, it actually did run fucking rock solid!!! But over time I lost the config and X.org doesn't like my dualhead setup all that much, especially the ultrawide display.
So, how about we address this issue for what it is already. THE OS FUCKING SUCKS!!!21 -

Linux gives you so much freedom, for example the freedom to fuck your system.
When i was experimenting with bootsticks i typed the following in the terminal:
sudo dd if=bootstick.iso of=/dev/sdb
Where is the mistake? The usb-stick was already plugged in at boot-time and since it was bootable linux mint named it /dev/sda.
You propably already realized it, i wrote the iso the my harddrive. My attempts to restore the partition-table failed, but luckily the kernel still had it in memory and i was able to backup my files via nautilus.
Still, i nearly had a heart attack11 -

So probably about a decade ago at this point I was working for free for a friend's start-up hosting company. He had rented out a high-end server in some data center and sold out virtualized chunks to clients.
This is back when you had only a few options for running virtual servers, but the market was taking off like a bat out of hell. In our case, we used User-Mode Linux (UML).
UML is essentially a kernel hack that lets you run the kernel in user space. That alone helps keep things separate or jailed. I'm pretty sure some of you can shed more light on it, but that's as I understood it at the time and I wasn't too shabby at hacking the kernel when we'd have driver issues.
Anyway, one of the ways my friend would on-board someone was to generate a new disk image file, mount it, and then chroot to that mount path. He'd basically use a stock image to do this and then wipe it out before putting it live.
I'm not sure exactly what he was doing at the time, but I got a panicked message on New Years Day saying that he had deleted everything. By everything, he had done an rm -fr /home as root on what he had thought was the root of a drive image.
It wasn't an image. It was the host server.
In the stoke of a single command, all user data was lost. We were pretty much screwed, but I have a knack for not giving up - so I spent a ton of time investigating linux file recovery.
Fun fact about UML - since the kernel runs in user space as a regular ol' process, anything it opens is attached to that process. I had noticed that while the files were "gone", I could still see disk usage. I ended up finding the images attached to their file pointers associated with each running kernel - and thankfully all customers were running at the time.
The next part was crazy, and I still think is crazy. I don't remember the command, but I had to essentially copy the image from the referenced path into a new image file, then shutdown the kernel and power it back on from the new image. We had configs all set aside, so that was easy. When it finally worked I was floored.
Rinse and repeat, I managed to drag every last missing bit out of /proc - with the only side effect being that all MySQL databases needed to be cleaned up.3 -
Just now, I managed to compile my first linux kernel for my laptop on the first try :D
Granted, it was just a single line to get my touchpad to work, still a great feeling.
Also, Nvidia is still going strong on my laptop, no problems whatsoever :)6 -
I bricked my Manjaro install by interrupting a kernel update like a fucking doofus.
After two hours of painstaking troubleshooting using a live image I finally resolved the issue. And man is that a good feeling. Solving complex problems (at least to me) on Linux is just such an amazing feeling ♥️12 -
To this day I can't figure out why people still drink the windows koolaid.
It's less secure, slower, bloatier (is that a word?), Comes with ads, intrudes on privacy, etc. People say it's easier to use than Linux, but 99% of what anyone does happens on a chrome based web browser which is the same on all systems!
When it comes to dev, it boggles the mind that people will virtualize a Linux kernel in Windows to use npm, docker, k8s, pip, composer, git, vim, etc. What is Windows doing for you but making your life more complicated? All your favorite browsers and IDEs work on Linux, and so will your commands out of the box.
Maybe an argument can be made for gaming, but that's a chicken an egg scenario. Games aren't built for Linux because the Linux market is too small to be worth supporting, not that the games won't work on it...25 -

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
*WiFi Connected*
YESSSS!!!!!!!!! My uptime is saved!
403 days and counting! YEAH BABY!!!

I'm the only one working on this anymore and every toolchain supporting the system (remember, we're using an ARM9 [initial strap CPU] AND an ARM11 (give or take an ARM7 slaved to the ARM9 that we don't have support for yet), all in tandem, and the only toolchain that remotely works is for ARM6 for some reason) hates the Linux kernel. Current goals: SD R/W support (currently RO), X, GNUTools, maybe a better fucking softkey driver (i'll have to find whoever made this one and fucking beat him), and a working joy2mouse/touch2mouse driver. Oh, and figure out if Swap would work either with the New 2DS/3DS' Bonus Drive (unused 64MB partition on NAND) without killing the NAND as the SD access is max. 1.2 MB/s read/write speed or so, which isn't fast enough for swap AND other things.
Currently working:
Busybox
Read-only SD support
Weston (term only, can't click)
Standard 3DS/Standard 2DS/New 3DS (Models before 2017, the non-foldables, rebranded standard 2DSes) features only, not yet New 3DS/New 2DS-enhanced
Currently failing final compile because toolchain:

"Kernel memory leaking Intel processor design flaw forces Linux, Windows redesign"
"Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we're looking at a ballpark figure of five to 30 per cent slow down"
"It is understood the bug is present in modern Intel processors produced in the past decade. It allows normal user programs – from database applications to JavaScript in web browsers – to discern to some extent the layout or contents of protected kernel memory areas."
"The fix is to separate the kernel's memory completely from user processes using what's called Kernel Page Table Isolation, or KPTI. At one point, Forcefully Unmap Complete Kernel With Interrupt Trampolines, aka FUCKWIT, was mulled by the Linux kernel team, giving you an idea of how annoying this has been for the developers."
>How can this security hole be abused?
"At worst, the hole could be abused by programs and logged-in users to read the contents of the kernel's memory."

With the announcement of WSL2, I am really concerned for linux DEs.
I use linux distros not just for the kernel but because most linux DEs do a far better job that windows ever will.
But the next gen programmers probably will never leave their shit systems for any distro because guess what... thay can just use WSLs.
I would probably have done the same.
You need to use a linux DE (Gnone/KDE/etc.) for at least a couple days to understand how great it is but people won't do it because windows is good enough and they can achieve most tasks in wsl.
Linux Foundation already doesn't care about DEs. (And why would they... Microsoft is filling their pockets).
I hope people still find wsl crap and have enough reasons to give any linux DE at least a few days try.

So my laptop is a Lenovo y50-70 and it's quite good. The keyboard is amazing compared to most other Laptops I've tried the screen is nice, it's durable and it's got some decent specs. With it (and also my desktop) I dual boot Kubuntu and Windows 10.
About three years ago I decided I wanted to reinstall both OS' since they were starting to get cluggered. Lo and behold I wasn't able to do that because, and I quote: "EFI USB Device boot failed".
Hours were spent trying to Google different things to the point where I was even desperate enough to go beyond page 0 on the different searches with (as you might have guessed), no luck. "Fuck that" I thought. It worked and I could clean it manually anyway.
Fast forward to the last part of August this year where I upgraded my Kubuntu from 17.10 to 18.04 and shit got weird. You can read more about it here:
https://reddit.com/r/kde/...
but the TL;DR is in the link. Windows was also quite annoing as well (but don't take my word for it).
As you might understand it made me really frustrated. I couldn't update my BIOS since they were already at the current version, but one way or another I had to fix it. After a while was almost about to give up when I decided to give this:
https://forums.lenovo.com/t5/...
https://bugs.launchpad.net/ubuntu/...
a go. It was weird though. Like imagine the conversation:
"Can't boot from USB bro, what do I do?"
"Just update your kernel, bro"
Well IT. FUCKING. WORKED.
So I imideatly installed Linux and have just now bothered installing Windows (since all of the teachers are vacation so I had plenty of time to set it all up).
But got damn.4 -
- booting Linux
- starting Clonezilla
- kernel panic after some time
- WTF, this used to work
- look at sensor values
- CPU is really hot
- CPU fan doesn't work
- BIOS warning disabled because the lowest regular fan level is 0 RPM
Luckily, I still had some cheap 120mm fan which is a bit louder, but works. What's astonishing is that in normal operation, i.e. without full load, the case fans alone provided enough air stream for the CPU cooler.8 -
The Linux Kernel is propably the best working example for open source.
Personally I had the most exciting experiences with open source games, like Super Tux Cart, OpenTTD, 0 A.D.
Once I watched a streamer playing OpenRCT2, but the Twitch integration server, which allows to have the names of the people in chat appear in the game, was offline. Because the game is open source, I was able to have a look at the API, write my own server in a couple of hours and share it. Was a really funny stream then!
Wine is a great project, too. I really like the idea that people cooperate with each other to bypass commercial limitations and on this way be able to play their favourite games on a free operating system. -
"CTO" here.
Two week ago the CEO informs me that the "investor" want to put me in contact urgently with an external software house to help me with my "bottlenecks".
The investor goes immediately on holiday, so it's not available for explanations. The CEO doesn't know much.
Today I meet the software house CTO and CEO.
They tell me that I should do a transfer of knowledge with them. That they will respect my requirements, my schedule and that they want to help me.
During the meeting the business consultant explains "his" vision. Some new development nobody understand. Not even the CEO. The other cofounder is probably in disagreement but stay silent.
I agree to cooperate with them in due time and with due scope and planning.
It appears they already signed a contract with the investor. The investor is offering to us 40 days of a senior developer, for "free".
The CEO doesn't even know the economical details of the contract and he is surprised that has been signed.He also didn't know that a person will come over for 40 (?) days and that we will have to pay the transfer expenses.
I try to be friendly. I explain to them the issues I need to solve. I say specifically that I need help on certain tasks and that my wish is that nothing "new" will start until we fix some obvious problems.
After leaving, in the evening I receive an email from the software house guy, telling me that next week I MUST allocate a slot for technical transfer and the 2 weeks after for on site training. Like that. He also mention we "agreed" on that which is false. We agreed on me deciding the timing.
We are only 2 developers, at the moment and the other one will be on holiday next week, so I'm trying to get from him a lot of things I don't know because I don't know everything.
I'm not even sure I'll be able to explain how to prepare all the environment.
Worst thing is that I don't know what will be the scope of the project.
I really don't know how to behave.
I wrote back setting my conditions. I have holiday too. I have to prepare "documentation", explanation, etc.
I don't want the "senior dev" coming when I'm not present.
Maybe I was too weak answering and I should have started a fight immediately. Because he actually AGREED to let me decide and after that he set conditions on me immediately.
I don't know.
My stomach is burning, I had a very bad digestion with fever and headache, feel like puking, plus I spent several evening hours fixing the fucking Linux kernel bug.
I want to survive. I don't want to let them oust me in this stupid way. I want to fight.
I know that if I will explode, scream or whatever I will be at fault and I'll accelerate my demise.
When I try to be "diplomatic" actually I end up being weak.
When I try to be assertive I'm in fact rude and hysterical.
I can't think anything else.
This is what burnout looks like.20 -

Ya'll know what... If humans weren't such annoying vulnerability-searching little shits then we wouldn't have had to implement any protection against them and think of all the performance that would be saved on that. Take branch prediction vulnerability mitigation in the Linux kernel for example, that's got to make a performance hit of least 10% on basically everything.
Alas, I do get why security is important and why we keep such vulnerability mitigation running despite the performance hit. I get why safe code is necessary but still... if these people weren't such annoying little bastards.
Yeah, I was just kind of set off by the above. So much would be faster and easier if only the programmers wouldn't have to plan for people exploiting their software. Software would be written much faster and humans would progress to stuff that actually matters like innovation.8 -

About a year ago, I started a new position as a Full Stack Java Developer. When I started my employer got me a brand new, shiny, Asus laptop. As I prefer Linux (mint) to perform my magic I had to whipe Windows 10 and reinstall it. It turned out that my new shiny laptop was in fact so shiny that Linux (mint) didn't support/contain all the necessary drivers (yet), especially the network/bluetooth drivers and the gfx's drivers turned out a bit of a pain.. Over the year things slowly got better with every new kernel update that came in. However, due to me trying to fix things before those updates, Linux also had become somewhat unstable.
So ... last week I took some time to re-install that laptop and also take the opportunity to upgrade from Linux mint 18 to Linux mint 19 ... or so I thought ... Linux mint 19 was running (very) hot to the point where the laptop would shutdown due to the MOBO's thermal protection mechanims kicking in. ... Ok ...maybe Linux mint 19 was not such a good choice .... let's see if Ubuntu 18.04 is an option ... Nope ... Linux would lock up within a minute after booting up ... no mouse, no keyboard ... nothing. .... *sigh* ... let's (re)install Linux Mint 18.3 again ... and behold, I can start performing magic again.
Linux, it can be such a pain at times. I still prefer it, but running into all those 'weird' things on my laptop when reinstalling, I have to admit I have seriously considered 'just' installing windows 10 again and be done with it. Luckily I could also remind myself of what a pain Windows is to do serious docker/java development in comparison to Linux which gave me the strength to keep going ... :)6 -

More often than not, I hear that the mission-critical stuff in Linux is done by paid people, the folks that work from 9 to 5 with a fixed time/resource schedule. Is software in Linux all like that? Say for example, Linux (kernel), systemd, Xorg, all the desktop environments, LibreOffice, Mozilla, Chromium and such.
The reason why I'm asking is because I kind of feel like the premise behind Linux "free, libre, *philanthropic*" and such is kinda wrong. Especially the latter. Do the people in the mission-critical stuff really care about its stability any more than commercial software devs do? Sure the projects driven by personal needs that are published are philanthropic in their nature, I'm having some of those too. But those are all non-critical and maintained as such. The stuff that's behind the steering wheel however? I'm not sure...
In essence, is the mission-critical part of the Linux ecosystem - however open-source it is - any different from other commercial software products QA-wise?3 -
finally got TI to cough up their SDK and I noticed there's no compiler or linker or anything. Turns out I need to use TASM.
...TASM is for MS-DOS or compatible. I'm on Linux.
Well, it went poorly, as usual, specifically like this:
- tried to automate building with DOSBox config and Python script: output binary always corrupted. Manually repeated, TASM mangles output on DOSBox every time. No PCem or 86box, and i'm on a Ryzen, so no KVM DOS. Out of luck there.
- TASM Linux build or wrapper? No build, but there is a wrapper! ...wait, it needs... 4 things written by random people to be made from source. I mean, that's not actually that bad... oh, after setting all of them up (and struggling through some autoconf/automake bullshit, one of the programs only had source for a 2.x kernel and autoconf/automake were not happy about it) it fails because one project's been worked on a lot more and dropped support for working with the other 3... goddammit.
- Community SDK? Several options for this... but all of them need .NET 2 to run on Win9x, don't work in Wine, or require... hey look, TASM! GODDAMMIT!
- DOS on a real machine? It's a massive bitch to shuttle files to and from a real DOS machine quickly and I can't take 30 minutes between builds that take me 4 minutes to change enough to need tested again.
why must i suffer like this22 -

This guy is wrong in so many ways.
"Windows/macOS is the best choice for the average user. Prove me wrong."
There are actually many Gnu/Linux based operating systems that's really easy to install and use. For example Debian/any Debian based OS.
There are avarage users that use a Gnu/Linux based operating system because guess what. They think its better and it is.
Lets do a little comparision shall we.

Cost $139 Free
Spyware Yes. No
Freedom Limited. A lot
"[Windows] It's easy to set up, easy to use and has all the software you could possibly want. And it gets the job done. What more do you need? I don't see any reason for the average joe to use it. [Linux]"
Well as I said earlier, there are Gnu/Linux based operating systems thats easy to set up too.
And by "[Windows] has all the software you could possibly want." I guess you mean that you can download all software you could possibly want because having every single piece of software (even the ones you dont need or use) on your computer is extremely space inefficient.
"Linux is far from being mainstream, I doubt it's ever gonna happen, in fact"
Yes, Linux isn't mainstream but by the increasing number of people getting to know about Linux it eventually will be mainstream.
"[Linux is] Unusable for non-developers, non-geeks.
Depends heavily on what Gnu/Linux based operating system youre on. If youre on Ubuntu, no. If youre on Arch, yes. Just dont blame Linux for it.
"Lots of usability problems, lots of elitism, lots of deniers ("works for me", "you just don't use it right", "Just git-pull the -latest branch, recompile, mess with 12 conf files and it should work")"
That depends totally on what you're trying to. As the many in the Linux community is open source contributors, the support around open source software is huge and if you have a problem then you can get a genuine answer from someone.
"Linux is a hobby OS because you literally need to make it your 'hobby' to just to figure out how the damn thing works."
First of all, Linux isnt a OS, its a kernel. Second, no you dont. You dont have to know how it works. If you do, yes it can take a while but you dont have to.
"Linux sucks and will never break into the computer market because Linux still struggles with very basic tasks."
Ever heard of System76? What basic tasks does Linux struggle with? I call bullshit.
"It should be possible to configure pretty much everything via GUI (in the end Windows and macOS allow this) which is still not a case for some situations and operations."
Most things is possible to configure via a GUI and if it isnt, use the terminal. Its not so hard

Dev of 15 years here. All my career historically started and evolved/revolved around Microsoft in one way or the other, so was my exposure to only DOS and the Windows as a child and growing up.
Like already discussed in multiple rants here, I was one of those naturally Windows -favoring ppl through all my life. That is not to say I didn't try Linux here and there, for hosting of personal projects, as one usually does. But it never quite stuck with me as a personal daily driver, mainly because all I ever needed for personal use was a browser, discord, and Steam/GOG/Epic Games store for gaming (work-wise I always had and still have company provided laptops which are OF COURSE Windows powered)
Anyway, maybe you can see where I'm going with this... I recently gave Nobara Linux a go (Glorious Eggroll's Fedora flavor, with some custom kernel patches) and I have to say, not thinking of going back to Windows at all.
Just a few thoughts on comparing two sets of experiences with Win vs Nobara
- Win definitely feels more sluggish
- Nobara's default desktop env was Gnome 42 with some extensions pre-enabled. I dove right into hacking/customizing it to my tastes and it looked glorious. Never would have achieved this customization with Win
- I was using RDP to remote into my work laptop from my personal desktop setup with Windows and I still successfully do so with Remmina now in Linux
- A week ago I dove deeper and installed Awesome window manager as a UI and mh boy does this feel intimidating at first. But then the allure of having nice window managing experience was too strong, and 15 years of coding do help with just seeing a new language and kinda feeling at home instantly (Lua language for AwesomeWM customization/themes). Fast forward a week and now I'm sitting happily with 3 monitor setup, one of them vertical, all properly auto aligned with arandr on startup, variety+wal for wallpaper auto circling and applying a theme out of main wallpaper colors every so often (+wrote a script to put those main colors into my RGB peripherals via OpenRGB)
- Gaming. I still game, Steam Deck from steam gave me all the confidence to set up Linux gaming that I needed. I think I am now properly versed in all things Wine/Proton/Lutris/Bottles/Heroic Games Launcher, you name it. Recently finished Cyberpunk 2077.
ANYWAY, thank you for coming to my Linux appreciation TED talk. It's amazing. -
Compiling software on Linux:
Python interpreter? Easy peasy, just some dependencies here and there. Make does a good job.
Linux kernel? Piece of cake, 20 years of development will be freshly served on your machine after one hour compiling (I have a pretty powerful computer).
Tensorflow? Fuck this shit I am outta.
What is your story with self-built software? Which piece of code has the most terrible dependency hell?5 -
Today, Linux kernel 5.8 was released, here is how it runs on my new laptop.
- Realtek shit ethernet still doesn't work (no, I didn't return it, because I would have to buy at least 2 times as expensive docking station instead and it is just not worth it), but considering Realtek, it is probably not a Linux kernel issue
- Battery life while watching videos was improved pretty significantly from 6.5 hours to about 7.3 hours (1080p HEVC)
- All temperature sensors are now working correctly
- Fan is a little more silent overall, probably because of some power draw improvements
- Subjectively, the system is a little bit more responsive overall4 -
Professors today in colleges don't know...
.
1. the proper denominations of outputs of basic shell commands like "ls -l", "cat", "cal" (pronounces linux as laynux)
.
2. how memory management works
.
3. how process scheduling actually takes place and not in the outdated bookish way.
.
4. how to compile a package from scratch and including digital signatures
.
5. cannot read a man page properly, yet come to take OS labs.
.
6. how to mount a different hardware
.
7. how to check kernel build rules, forget about compiling a custom kernel.
.
.
.
n. ....
Yet we are expecting the engineers who are churned out of colleges to be NEXT GEN ?!
It is not entirely because of syllabus, its also because of professors who had not updated their knowledge since they got a job. Therefore they cannot impart proper basics on students.
If you want things to change, train students directly in the industry with versions of these professors UPDATED.6 -
I really really really need more RAM. 16GB is far from enough. Had to witness the kernel kill all of my Chrome extensions and most of my tabs and an IDE and still it wasn't able to run that container in the 8G RAM it just freed up...
I remember the days when 8G RAM was an overkill.
The times have changed. Now I'm looking into getting a Linux lappy w/ 96GB and still worried whether it'll suffice my needs....11 -
I'm freaking done trying to get Linux on my machine. I've tried every distro with many different versions of the kernel and I always run into the same problem on my desktop.
The computer super stutters for 2 seconds ish than freezes.
I've spent DAYS looking into this issue trying to find something. The worst part is that it can happen 5 minutes when I boot or 5 hours. At first I thought it was Compton. Then I thought I installed arch wrong. Maybe an update to the BIOS? How about downloading updated microcode? Maybe this obscure bug with AMD processors and setting power idle to typical? Nothing. I'm now behind on my school work because of the massive amount of time ive spent getting this fixed. It works just fine on my laptop, but it doesn't work on the machine I built to code with. I'm done. Give me Force Lightning, a red lightsaber, and call me a Sith baby because I'm joining the dark side. Here I come Windows.
For those who are wondering my setup:
Ryzen 7 1700
Rx 480
Asus x-370 prime
16 gb Corsair RAM
And no, Windows has never had this bug.31 -
Tl; dr: Linux on Ryzen is a pain at the moment.
Now for the long part: Our student council got new computers because the old ones where slow as hell. As one of the admins, the others and I together decided that ryzen would be a good option, because they are not that expensive and we wouldn't have to buy gpus. (Wrong decision it turns out.) We settled on the ryzen 3 2200G and bought three systems to replace the old ones.
We meet Saturday morning and build the systems. All was fine and we were happy. The we tried to install ubuntu via preseeded netboot, which seemed to work fine at first. Then we started having weird screen issues and couldn't proceed with the installation. (See image) we then grumpily decided to just install them all one by one, flashed two usbs and started installing. On two systems the installation worked and we installed our packages, we weren't so lucky with the third one. It would crash on us all the time, even in bios. While that was going on we tried to set the other two up, turns out those two were also crashing but not as frequent as the other one. So we start to google and find people saying that kernel 4.19 kinda fixes it. We install it on the two working machines and the crashes get less frequent but are still there. At that point it was midnight and we went home.
Sunday morning: we reseated the cpu on the third system and it seems to be better now (it installed on the second try) and we were able to change the kernel. Yay. Now all three are in a state where they will sometimes randomly reset. :/ and we don't know what to try anymore.... Any suggestions?1 -
A bug is born
... and it's sneaky and slimy. Mr. Senior-been-doing-it-for-ears commits some half-assed shitty code, blames failed tests on availability of CI licenses. I decided to check what's causing this shit nevertheless, turns out he forgot to flag parts of the code consistently using his new compiler defines, and some parts would get compiled while others needed wouldn't .. Not a big deal, we all make mistakes, but he rushes to Teams chat directing a message to me (after some earlier non-sensible argument about merits of cherry picking vs re-base):
Now all tests pass, except ones that need CI license. The PR is done, you can use your preferred way to take my changes.
So after I spot those missing checks causing the tests to fail, as well as another bug in yet another test case, and yet another disastrous memory related bug, which weren't detected by the tests of course .. I ponder my options .. especially based on our history .. if I say anything he will get offended, or at best the PR will get delayed while he is in denial arguing back even longer and dependent tasks will get delayed and the rest of the team will be forced to watch this show in agony, he also just created a bottleneck putting so many things at stake in one PR ..
I am in a pickle here .. should I just put review comments and risk opening a can of worms, or should I just mention the very obvious bugs, or even should I do nothing .. I end up reaching for the PM and explained the situation. In complete denial, he still believes it's a license problem and goes on ranting about how another project suffering the same fate .. bla bla bla chipset ... bla bla bla project .. bla bla bla back in whatever team .. then only when I started telling him:
These issues are even spotted by "Bob" earlier, since for some reason you just dismissed whatever I just said ..
("Bob" is another more sane senior developer in the team, and speaks the same language as the PM)
Only now I get his attention! He then starts going through the issues with me (for some reason he thinks he is technical enough to get them) .. He now to some extent believes the first few obvious bugs .. now the more disastrous bug he is having really hard time wrapping his head around it .. Then the desperate I became, I suggest let's just get this PR merged for the sake of the other tasks after may be fixing the obvious issues and meanwhile we create another task to fix the bug later .. here he chips in:
You know what, that memory bug seems like a corner case, if it won't cause issues down the road after merging let's see if we need even to open an internal fix or defect for it later. Only customers can report bugs.
I am in awe how low the bar can get, I try again and suggest let's at least leave a comment for the next poor soul running into that bug so they won't be banging their heads in the wall 2hrs straight trying to figure out why store X isn't there unless you call something last or never call it or shit like that (the sneaky slimy nature of that memory bug) .. He even dismissed that and rather went on saying (almost literally again): It is just that Mr. Senior had to rush things and communication can be problematic sometimes .. (bla bla bla) back in "Sunken Ship Co." days, we had a team from open source community .. then he makes a very weird statement:
Stuff like what Richard Stallman writes in Linux kernel code reviews can offend people ..
Feeling too grossed and having weird taste in my mouth I only get in a bad hangover day, all sorts of swear words and profanity running in my head like a wild hungry squirrel on hot asphalt chasing a leaky chestnut transport ... I tell him whatever floats your boat but I just feel really sorry for whoever might have to deal with this bug in the future ..
I just witnessed the team giving birth to a sneaky slimy bug .. heard it screaming and saw it kicking .. and I might live enough to see it a grown up having a feast with other bug buddies in this stinky swamp of Uruk-hai piss and Orcs feces.1 -
I like how a co-worker is expecting a Windows Container to work in Linux, and vice versa.
No, it doesn't work like that you fucking baffoon, Linux rootfses needs the Linux kernel (hence why it runs on WSL2 or Hyper-V using LCOW), and same can be said for Windows Containers.
How dumb of a human being must you assume everything should "just work" in a container?5 -
I love Nvidia's apathetic attitude to Linux support. It makes it so much more economical for me every time I need to upgrade my GPU - the mid-upper tier previous generation cards are always available for around the same price as a lower tier current generation card. There is no buyers remorse when the only things I'm missing out on by not going bleeding edge are kernel panics and random reboots.4

Well shit, now I (re-)learned C,
And all I want to do is program in C,
But all C jobs are like -
"C guru that merged to Linux kernel"
"Driver writing low level must know Assembly"
"Military-grade realtime hardware design"
Isn't there a C job that's like Python - "here I wrote this script in 5 minutes and spent the rest of the day playing Eve Online" :D :D10 -
First of all, a great channel to follow and where all this is from: https://youtube.com/watch/...

Proxmox team, go fuck yourselves.
Now I'm sure that I'll receive a lot of flack for this, but hear me out.
I've tried Proxmox and was quite pleased with its web UI. But I hate how much it locks me into their own little ecosystem.
I want to use btrfs on my drives. Why is this impossible, yet the hack that is ZoL is your obvious alternative? An alternative wherein I can't even compile and run my own kernel, because then ZoL suddenly fails? And don't you tell me to compile your stock config, when it's well over 15GB large in your source tree.
Proxmox is literally the MacOS of Linux distributions. Which was even more so made clear by me being called an idiot by possibly wanting to run Same on the PVE host. Because why on Earth would sysadmins want to?! Why on Earth would sysadmins be competent for wanting to?!!
You know what? I'll just convert those Proxmox servers to Arch and say fuck you to all the bells and whistles that's Proxmox' web UI. Because at least Arch allows me to make my own fucking choices, limited only by what's supported by the Linux operating system.
Perhaps Proxmox will consider btrfs stable in 2021. Because you know, despite it being stable today in 2018, Debian and Proxmox alike live 3 years in the past, i.e. 2015. I hate the Debian ecosystem because of that, but boy do I hate Proxmox even more so. Bloody fucking piece of shit it is!!! 😡6 -
Okay so my brother in law has a laptop that is... To put it mildly, chockful of viruses of all sort, as it's an old machine still running w7 while still being online and an av about 7 years out of date.
So my bro in law (let's just call him my bro) asked me to install an adblock.
As I launched chrome and went to install it, how ever, the addon page said something like "Cannot install, chrome is managed by your company" - wtf?
Also, the out of date AV couldn't even be updated as its main service just wouldn't start.
Okay, something fishy going on... Uninstalled the old av, downloaded malware bytes and went to scan the whole pc.
Before I went to bed, it'd already found >150 detections. Though as the computer is so old, the progress was slow.
Thinking it would have enough time over night, I went to bed... Only to find out the next morning... It BSoD'd over night, and so none of the finds were removed.
Uuugh! Okay, so... Scanning out of a live booted linux it is I thought! Little did I know how much it'd infuriate me!
Looking through google, I found several live rescue images from popular AV brands. But:
1 - Kaspersky Sys Rescue -- Doesn't even support non-EFI systems
2 - Eset SysRescue -- Doesn't mount the system drive, terminal emulator is X64 while the CPU of the laptop is X86 meaning I cannot run that. Doesn't provide any info on username and passwords, had to dig around the image from the laptop I used to burn it to the USB drive to find the user was, in fact, called eset and had an empty password. Root had pass set but not in the image shadow file, so no idea really. Couldn't sudo as the eset user, except for the terminal emulator, which crashes thanks to the architecture mismatch.
3 - avast - live usb / cd cannot be downloaded from web, has to be installed through avast, which I really didn't want to install on my laptop just to make a rescue flash drive
4 - comodo - didn't even boot due to architecture mismatch
Fuck it! Sick and tired of this, I'm downloading Debian with XFCE. Switched to a tty1 after kernel loads, killed lightdm and Xserver to minimize usb drive reads, downloaded clamav (which got stuck on man-db update. After 20 minutes... I just killed it from a second tty, and the install finished successfully)
A definitions update, short manual skimover, and finally, got scanning!
Only... It's taking forever and not printing anything. Stracing the clamscan command showed it was... Loading the virus definitions lol... Okay, it's doing its thing, I can finally go have dinner
Man I didn't know x86 support got so weak in the couple years I haven't used Linux on a laptop lol.9 -
I always feel inspired by programming when I create some algorithms or programs which I can use when I need to.
Small utilities and command line programs r what I make at times... and I also enjoy trying to implement them awesome algorithms 😍
However, most inspiration I get is from looking at C code though ( especially the Linux kernel... that code is SO clean 😍😍 )2 -
It's amusing how every time something doesn't work with Linux somebody spent a bunch of time customising their OS into oblivion (because well, the whole point of using Linux is the ability to have it your way, d'oh), and it's never their fault for changing everything or using some distro with 0.05% market share, it's the company's fault not providing bulletproof support for their exact setup and not testing everything they put out on every combination of kernel & system software.6
-
Don't understand what the hype about Elementary OS was. Used for ca. half a year, do not see any benefit.
If this is supposed to provide "usability" on a Linux kernel, then I am sorry, but in this regard it is a tremendous failure.
All tasks take long, there are all sorts of bugs, today I needed a multi-monitor setup for a presentation "real quick", dear lord was that a shitshow.
Nah, this thing is not for me.14 -
Avoid ACPICA if at all possible. It's one garbage tier cluster fuck of bad design, horrible documentation and downright misleading and wrong code
It's meant to consist of an ASL compiler, disassembler, debugger, dumper, various user space utitilies and a kernel resident OSPM implementation *if* you can figure out what belongs to what. Even just compiling this pile of trash is a mystery in itself. Think you need the source files in source/common? EEEEH, wrong. Well, at least partially since most of them seem to be for the user space stuff..? Other ones *are* needed on the other hand. At least the disassembler and/or debugger and/or dumper components seem to reference them. Not that I could figure out how to compile those anyways. The real path to your goal seems to be to ignore a seemingly arbitrary subset of source and header files until your linker stops complaining
There's also a bunch of configuration defines, some of which *you* define, some defined *for* you, based on again others. Of course most of them do stupid shit. Enabling the debugger automatically enables debug logging. Enabling the disassembler force enables debug allocation tracking... What?
The code itself isn't of much help either. Looking in "os_specific/service_layers" you find what looks to be reference implementations of acpica functions in certain os' like windows and unix. Of course I had a look because AcpiOsReadMemory is supposed to read physical memory and I don't know how I would even implement that. But hey, osunixxf.c (xf for interface... of course) should tell me. I'll let you see for yourself in the attached image. Apparently it does fuck all and just returns AE_OK. No error, no logging, no nothing. Just ok. As you can imagine, AcpiOsWriteMemory doesn't do much more either.
...okay so maybe physical memory accesses aren't actually used and these functions are some sort of relic from past times? Nope! They are absolutely necessary for doing low level device interaction. WTF. So finally I went to the linux source and checked how *they* implemented them, and just as I thought, these functions are anything but no-ops...
...So for what fucking reason do these stupid interface implementations even exist but to purposefully mislead you?? They aren't used for fucking anything! As far as I know Windows doesn't even *use* ACPICA and Linux have their own fork with working implementations... They just sit there, just to tell you how to NOT do it
So that's some of my thoughts about ACPICA. Note that I haven't even used it as a library yet, I just got it to compile and link and it already fucked with me this much.
There's also so much more I didn't mention like that you *have* to modify the acpica source in order to get your own platform header working (else #error) eventhough the docs explicitely instruct you not too but you get the point
Don't use ACPICA if you don't have to. Save your sanity for something that's worth it -
I can't decide on a linux distro because all I've tried are great. Seriously.
I'd call myself a novice-to-intermediate linux user (heavy on the novice part) and since I work as a web developer it's been a great learning experience to use the same OS on my workstation as the webservers my projects run on. (Ie I started out with Ubuntu and a LAMP setup).
The thing is I distrohop ad infinitum... Feels like I've tried out every desktop environment known to mankind (I just can't stop myself when I see a new one or a new take on an old one) and I've dipped my toes in Arch territory to. Loved Antergos when that still was a thing. Found EndeavourOS this weekend, kernel panic ensued. I'm a noob with sudo and that's never a good thing. 😆 (Try out in a virtual machine first you say? Bah. Where's the fun in that?!)
So now I'm on Linux Mint w Cinnamon because why not. (Because it's sluggish and boring, that's why...) I had to just get something up and running quickly so I could get back to work. 😬
But one day in and I'm realising I actually miss GNOME. And Ubuntu feels like home. I would feel much cooler using Arch but honestly I don't think I can be trusted with it. I love tinkering with settings, look and feel and whatnot but I can honestly do that just as well in an Ubuntu/GNOME environment.
Maybe Pop!_OS... could be something for me. 😏20 -
fuck oracle. fuck my company.
Using Oracle VM Manager/Servers to host Oracle Phone transfer solution without support coverage from Oracle.
Requiring Unix sysadmins to update to latest release and not telling that we do not have coverage from Oracle if anything goes wrong.
Gues what.. We've updated to Oracle VM Manager/Server 3.4.5 which was released this year and it uses fucking XEN hypervisor version 4.4.4 which has been deprecated and dead since who knows when. Latest release of XEN is 4.11. But that is not an issue, whatever, enterprise, legacy software, etc.
This fucking update introduced memory leak on the hypervisor which has been reported as per xen 4.4.4 history. Furthermore, we have no support from Oracle which means that I have to dig through mailing lists and limited information on the net since oracle has freakin support wall on nearly each of the major bugs found on that shitty software.
I have no idea whether any newer version of xen will work with that old Oracle Linux kernel or not.
Furthermore, Oracle provided great documentation on how to rollback the fcking update. Reinstall the hypervisor. Riiiight. XEN does not have export/import feature.

When did the meaning of
"Statically linked", under Linux, change from
This binary includes all libraries it depends on and will run on any device that runs a sufficiently compatible hardware and kernel.

I'd just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use.
Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.9 -
Time for a rant about shitstaind, suspend/hibernate, and if there's room for it at the end probably swappiness, and Windows' way of dealing with this.
So yesterday I wanted to suspend my laptop like usual, to get those goddamn fans to shut up when I'm sleeping. Shitstaind.. pinnacle of init systems.. nope, couldn't do it. Hibernation on the other hand, no problem mate! So I hibernated the laptop and resumed it just now. I'm baffled by this.
I'll oversimplify a bit here (but feel free to comment how there's more to it regardless) but basically with suspend you keep your memory active as well as some blinkenlights, and everything else goes down. Simple enough.. except ACPI and I will not get into that here, curse those foul lands of ACPI.
With hibernation you do exactly the same, but on top of that, you also resume the system after suspending it, and freeze it. While frozen, you send all the memory contents to the designated swap file/partition. Regarding the size of the swap file, it only needs to be big enough to fit the memory that's currently in use. So in a 16GB RAM system with 8GB swap, as long as your used memory is under 8GB, no problem! It will fit. After you've moved all the memory into swap, you can shut down the entire system.
Now here's the problem with how shitstaind handled this... It's blatantly obvious that hibernation is an extension of suspend (sometimes called S3, see e.g. https://wiki.ubuntu.com/Kernel/...) and that therefore the hibernation shouldn't have been possible either. The pinnacle of init systems.. can't even suspend a system, yet it can hibernate it. Shitstaind sure works in mysterious ways!
On Windows people would say it's a hardware issue though, so let's talk a bit about that clusterfuck too. And I'll even give you a life hack that saves 30GB of storage on your Windows system!
Now I use Windows 7 only, next to my Linux systems. Reason for it is it's the least fucked up version of Windows in my opinion, and while it's falling apart in terms of web browsing (not that you should on an EOL system), it's good enough for le games. With that out of the way... So when you install Windows, you'll find that out of the box it uses around 40GB of storage. Fairly substantial, and only ~12GB of it is actually system data. The other 30-ish GB are used by a hibernation file (size of your RAM, in C:\hiberfil.sys) and the page file (C:\pagefile.sys, and a little less than your total RAM.. don't ask me why). Disable both of those and on a 16GB RAM system, you'll save around 30GB storage. You can thank me later.
What I find strange though is that aside from this obscene amount of consumed storage, is that the pagefile and hibernation file are handled differently. In Linux both of those are handled by the swap, and it's easy to see why. Both are enabled by the concept of virtual memory. When hibernating, the "real" memory locations are simply being changed to those within swap. And what is the pagefile? Yep.. virtual memory. It's one thing to take an obscene amount of storage, but only Windows would go the extra mile and do it twice. Must be a hardware issue as well.
Oh, and swappiness. This is a concept that many Linux users seem to misunderstand. Intuitively you'd think that the swappiness determines what percentage of memory it takes for the kernel to start swapping, but this is not true. Instead, it's a ratio of sorts that the kernel uses when determining how important the memory and swap are. Each bit of memory has a chance to be put into either depending on the likelihood of it being used soon after, and with the swappiness you're tuning this likelihood to be either in favor of memory or swap. This is why a swappiness of 60 is default most of the time, because both are roughly equally important, and swap being on disk is already taken into account. When your system is swapping only and exactly the memory that's unlikely to be used again, you know you've succeeded. And even on large memory systems, having some swap is usually not a bad idea. Although I'd definitely recommend putting it on SSD in a partition, so that there's no filesystem overhead and so that it's still sufficiently fast, even when several GB of memory are being dumped in.6 -
How long is your operation system running?
Linux - since the first kernel release I've ever touched.
Windows - depends on the update cycle, mostly 2 weeks up to 6 month.
And there goes another night with reconfiguring my windows session 🤬.6 -
It's fucking sad that when you buy a new laptop with good specs, good nvidia graphics, good sound and install Arch Linux because you hate fucking windows and arch way is the right way. But, then Linux fucks you because there is no proper nvidia support and you have to use wine which doesn't support new games and you run frequently into problems like audio (P.s. maybe in linux 4.10.11). You have to configure microphone everytime while using Skype and see some other guy having same laptop playing happily latest games without much burden.😣😣😥😥😔😔
When will Linux kernel be amazing for gaming??13 -
Hello! My name is opalqnka and I am a Windows user.
I followed the 12-step program and now I am a step away to being certified LPIC Linux Engineer.
As step 12 preaches, here I humbly share the Program:
1. We admitted we were powerless over Windows - that our lives had become unmanageable.
2. Came to believe that a Power greater than ourselves could restore us to sanity.
3. Made a decision to turn our will and our lives over to the care of Linus as we understood Him.
4. Made a searching and fearless moral inventory of ourselves.
5. Admitted to Linus, to ourselves and to another human being the exact nature of our wrongs.
6. We’re entirely ready to have Linus remove all these defects of character.
7. Humbly asked Him to remove our shortcomings.
8. Made a list of all persons we had harmed, and became willing to make amends to them all.
9. Made direct amends to such people wherever possible, except when to do so would injure them or others.
10. Continued to take personal inventory and when we were wrong promptly admitted it.
11. Sought through bash scripting and kernel troubleshooting to improve our conscious contact with Linus as we understood Him, praying only for knowledge of His will for us and the power to carry that out.
12. Having had a spiritual awakening as the result of these steps, we tried to carry this message to Windows users and to practice these principles in all our affairs.4 -
You may soon have a new operating system from Google to run on your Raspberry Pi. Details are still extremely sparse, the only description on the GitHub page is “Pink + Purple == Fuchsia (a new Operating System)”. But, here’s what we do know:
The new OS, called Fuchsia, will be based on Magenta, which is in turn built on LittleKernel. That means that, surprisingly, Google will not be using a Linux kernel for the new OS but something more like an embedded RTOS. Although Google is targeting embedded systems, the possibility of being able to run it on a desktop has been mentioned, so it may not be too minimalistic.
Google’s Travis Geiselbrecht has named the Raspberry Pi 3 specifically as one system it will run on, and said that it’ll be available soon. But, it seems Google is aiming to make it run on a variety of ARM devices (both 32 bit and 64 bit), as well as 64 bit PCs. This is a direct effort to compete against other commercial embedded operating systems that are currently available, and especially on IoT devices.1 -
Oh boy, linux NFS bugs! this was supposed to be fixed in 2.x, but here I am, in kernel 6.1, same issue! `nfsiod` hangs, can't SIGKILL/SIGSEGV/SIGXCPU as root, `/proc/$pid/maps` is empty, strace/gdb are denied while running as root for only this process, `/proc/$pid/stack` only shows a single kthread that's stuck waiting for a fork to return, and... what the hell is `rescuer_thread`? apparently, deprecated in kernel 3.10, whatever the hell it is... wait, how did this even make a call without memory?
it's gonna be one of those days, isn't it?2 -
is it fair to say linux is the most popular operating system kernel?
i mean, it powers android, the most popular mobile os, chrome os, nearly all servers, raspberry pi’s, embedded devices and linux desktop operating systems. it has the be the most popular kernel, right?7 -
First rant that I really want to get out of my chest!
Never hated a job as much as this one. Haven’t done any development/programming related work since I joined. I have been mostly configuring Linux systems for IoT devices. When I get stuck at an issue, it takes me many frustrating nights to figure it out because no one on the team wants to deal with Linux shit… they’d rather be doing real development work (someone actually stated this!). There’s no one else on the team that knows Linux. Even the manager that was supposedly a Linux fanatic can’t even answer some of my questions and if they do, it’s the wrong fucking answer. Joined the company because they sold it as startup team with big money backing. Was excited to learn new technologies, new best software engineering practices, add new programming languages to my resume. But nope, been stuck at configuring Linux systems. At one point I was just pumping out updated Linux images with our updated application for a month straight. I was so excited when a development task was assigned to me a couple weeks back, but guess what?! There were Linux configuration tasks that no one knows how to do or don’t want to look at it, so my one and only fucking development work was swapped out!
And the funny thing is, I barely had any Linux experience when I joined. Why the fuck was I hired?
Man, I even bought books related to Linux programming (application and kernel) before I joined. Those books barely have a crease in them. What a waste.
Now in my free time, I’ve been learning new technologies on my own. Doing my own projects. But damn, I lose a lot of family time. Sorry wifey, I haven’t been paying a lot of attention to you!
But who knows, maybe this experience will have a silver lining in the end.
Thanks for reading :)2 -
Setting up npm private registry and mirror is like setting up machine for handling ddos attack.
Last time I was tuning linux kernel tcp ip stack by adjusting default variable values was ages ago but if you see 100 open sockets in a matter of second after you try to install single frontend dependency you start questioning your life. -
Why is it that the tech Youtubers of this world (and tech reviewers in general) tend to completely skip development as a use case, and instead (if they do ever move off gaming) focus on things like Rendering & Modelling / CAD work? I'm sure there's *way* more devs in the world than CAD guys, surely?!
And if they *do* give it the light of day, it's always a quick benchmark based on "Firefox compile time", "Linux kernel compile time" or similar. Dude, it's 2020. Much as some would like to believe otherwise, most guys stopped compiling swathes of heavy C & C++ as part of their normal workflow over a decade ago.
Real-world tests I want to know about are things like docker performance, common IDE startup performance, compile performance of different sized applications on a bunch of langs like Kotlin, C#, Java, Clojure - or node.js performance, Tensorflow performance on NVidia's vs AMDs latest GPUs, etc. I care about how many IntelliJ instances & VMs I can have open way more than how many Chrome tabs I can forget to close.
But noooo - forget that, here's how fast Blender can render a BMW! 😬5 -
it would help if i had time to learn even a little more C, as I'm bumbling my way through the Linux kernel and GodMode9 (an amazingly powerful 3DS manip tool for everything from the SD card to the NAND to literally raw FIRM0/FIRM1 bootloader access) to try amd patch some code from GM9 into the kernel to handle the SD card *properly* so Linux 3DS doesn't constantly hang when reading/writing to the SD card, to enable Wi-Fi access (same bus location and similar bus structure as SD/NAND access, different processor,) enable NAND decryption and access (yes, really, NAND is encrypted via software, which is... ...fun...) and more.
tl;dr: the 3DS hardware, C, and others' code collectively make me wanna slit my fucking wrists. Hopefully my sacrifice allows higher-level programming languages to be visble for low-level jobs in the future.4 -
Erm not sure if this qualifies. Not so long ago I was tackled with having to read a device memory at a very high address in 32-bit linux process (kernel is 64). The 32-bit mmap is unfortunately limited to range of protected mode PAE so it just wouldnt reach that high. So! I wrote my own syscall in assembly that would switch to long mode first so I could use long registers and then I got my page and switched back :)
In retrospective not a big deal, but it made me really happy for the rest of the day when I saw that address in pmap :)1 -
School made me a stickler for the Linux kernel coding conventions in regards to the C language. And even though I shouldn't feel bothered by reading other coding styles.....i still get annoyed.
I try not to get irked cuz I find it a small thing to get annoyed at.... but i still do.....bad.
And even then i dislike how there is not padding inside of funcion parametes
void
fu(int here, int there) {}
Should be
void
fu( int here, int there ) {}
That space man...its needed.
Man this is such a small thing to be annoyed at..3 -
Quick question/update over a previous rant.
My netbook battery status was always 100% on Lubuntu 18.10, I switched to Xubuntu and the same happens, but it reports correctly with Puppy Linux (old version). I thought the problem was in the battery itself, but now I think it's due to some broken drivers in newer version of Debian-based distros, or it is a bug in newer Linux kernel. But since I have no time to spend on a spare netbook, I'm not willing to test more options.
Anyone has a clue? 🤔

Reading about tasklet and workqueue in linux kernel and this happened:
Caution
The name 'tasklet' is misleading: they have nothing to do with 'tasks', and probably more to do with some bad vodka Alexey Kuznetsov had at the time.
This rant is brought to you by official linux kernel documentation.

Ugh am so done with linux.
I dualbooted ubuntu 16.4 LTS alongside win10 on my new laptop 3 years ago. Back then , the whole os and kernel stuff were new for me, but once i understood how things work in it, i always found linux to be a superior alternative for doing any development related task than windows.
The way terminal gives us sheer raw power to handle services and applications ourselves makes everything easy in linux.
Wanna run a lamp server? Install all parts by yourselves. Problems with the lamp server? You are just 1 command away to know which service/package is causing issue. Some python module fucked up? You can go on checking every package present anywhere on your disk. No permissions? Sudo.
But recently i got so much fed up of its gui. I have gone from 16.4 to 18.4 to 20.4 , but no version seems to handle multiple gui s/w running parallely .
I usually have the requirement to open 2-3 windows of chrome with 30-40 tabs, 1-2 projects of Android studio and studio emulator. But this shit blows even with just 1 project open on studio and nothing else! The even the keyboard and mouse gets stuck when i studio is making a built.
And don't get me started on how slow my system becomes when switching b/w AS and chrome :''( . Maybe there's issue with the dual boot or because i gave very large swap/root partitions when i first dualbooted or something else , but i am in so much pain :/
Finally i went back to win10 a month ago and was a little surprised to find that it sucks a little less now. Aside from the ugly forceful updates, it has been a breeze for working . The builds take longer time (fuck windows defender), but My Android studio (and everything else) does not lag when switching between multiple processes. I even once ran an emulator instance and it was still working fine . The process management of windows is very good.
I have heard that mac is kind of in middle of the 2 and better than both providing rich process management and powerful terminal commands . Waiting for the day when i have enough money(or no longer require my kidney) to buy and maintain a MacBook :/14 -
I've recently gotten this idea to take a Chromebook and run Linux on it.
Why a Chromebook, you ask? Well ChromeOS is a Linux kernel, boots using coreboot, and Google now requires that OEMs support LVFS (fwupd), i.e. the Chromebook is a very Linux friendly laptop.
Some other reasons I would use a Chromebook are: it's cheap, basically useless otherwise, amongst other things.
So, what do you guys think, good idea or not?14 -
Discovered this dumb backdoor into http://tutorialspoint.com/codinggro... months ago (June 2019). It's in Project>Compilation Options
It lets you execute any command on their server. I found a lot out:
The system is Red Hat based (Fedora/CentOS/RHEL)
It uses Linux kernel 3.20
It has 251GB of RAM
It has an 800GB HDD
Its IP is 172.17.0.2
Its main username is cg
It uses systemd init8 -
Working with the Intel Edison. My god that thing sucked. So the thing ships with this tiny custom yocto Linux with almost no common packages the default repositories. Getting basic tools like Git and Vim were a task on its own, let alone getting the latest version of Node running. Another company Emutex made a Debian distro for it called Ubilinux but they never planned support or updates and officially took it down a few months ago. Both the Yocto build and the Debian build shipped with the 3.10 Linux kernel and upgrading it without breaking it was nearly impossible because they monkey patched device support into it rather than making a patcher. The team at Linux responsible for the Edison released 3 broken versions of the MRAA library in a row, crippling my code for weeks before I realized what they had done. The hardware hasn't received a refresh since it came out and only 1.4 GB of the 4 GB on the device is actually available.
It may be fine for hobby projects but please don't ever try to prototype a commercial product on it. Fuck the Edison and fuck Intel2 -
Ahem id like two superpowers please ,
Then first one would be to telepathically nerf down parasitic ideas instantly, I could actually be the next superman if I had this.. Could save a lot of lives in the developer realm.
The second one is the power to instantly fix any kernel / driver / boot problem and make everything compatible with Linux2 -
I've been noticing that without any specialization development can become repetitive, as in, a bunch of fancy ways of doing the same CURD operations.
Something that just calls me is low level development, wether it is embedded development (microcontrollers and such) or Linux Kernel and device drivers. I've been polishing my C skills for a while now and started to look into kernel development and uff, is it overwhelming!
I just wanted to see if some of you guys are or had experience in system development and how you got there. Thx!3 -
TLDR; WINE+me=system binaries gone. (HOWTHEFUCKDIDIDOTHAT) Kernel panic. Core program files gone. I'll never have it fixed right. Will backup, then install fedora tomorrow.
I really like games and I'm sure there are many of you who can relate. Imagine my perpetual pain, being on the job hunt, no money, and only my Linux laptop for games. (It's only Linux because of a stupid accident and a missing windows installation disk, partly explained in a previous rant). My stack of games my dad and I have played over the years, going back to populous and before, looked light enough for my laptop to run them smoothly. I wanted to see if I could get one to work. My eyes settled on simcity 4 and Sid Meier's railroad tycoon, 13 and 10 years old, respectively. Simcity didn't work as many times as I tried following online instructions. Disk 1 went fine. Disk 2 showed up as Disk 1. Didn't think much of it, so long as the computer could read the contents. I downloaded playonlinux as that could apparently do the complex stuff for me. Didn't work. I gave up with it after an hour and a half.
Next was railroads. Put the disk in aaaand it says SimCity disk 1 is in the tray. Fuck right off, thank you very much. Eject, put back, reject, eject, fiddle in wineconfig, eject, more of this, and voilà it read as railroads :) Ran autoplay.exe with wine, followed instructions, installed it, and it worked! Chose single player, then the map and setting, pressed play, and all the models of the buildings and track were floating in the air over a green plane, the UI is weird and the map doesn't represent anything but trains. All the fkin land is gone, laying track is gonna be a ballache.
I quit it and decided bedtime.
Ctrl+alt+t
sudo shutdown -h now
shutdown not found.
sudo reboot
reboot not found
Que?
Nope, I don't like this.
Force choked my laptop by the power button. Turned it on again.
Lines of text appear.
Saw a phrase I've only ever seen on Mr Robot.
Kernel panic.
Nooooo thanks, not today, this is fiction.
I turned it off and on. Same thing. I read the logs and some init files couldn't be found. I got the memory stick I used to install mint in the first place and booted from that. I checked the difference between my stick's bin and sbin and the laptop's, and it was indeed missing binaries. Fuck knows what else has happened, I only wanted to play games but now I don't know what is or isn't in my computer. How can I trust what's on it now?
I go downstairs and tell my dad. He says something about rpm, but this is Linux so it won't work. I learn that binaries can be copied over, so maybe I can fix it.
Go upstairs again, decide not to fix it. Fedora is light, has a good rep for security, and is even more difficult to get games on, which is my vice. There are more reasons, but the overriding one is that I'm spooked by the fact that something I did went into and removed system binaries, maybe even altered others, so I want something I'm less likely to do that with. Also my fellow cs students used to hate on it but my dad uses and recommended it so I want to try it.
Also, seriously, fuck wine/PlayOnLinux/my inability to follow instructions(?)/whatever demons haunt me. Take your pick, at least one if not more is to blame and I can't tell which, but it's prooooobably the third one.
It's going to be 16 hours before I touch my laptop again, comments before I backup then install fedora are welcome, especially if they persuade me to do differently.
P.S thanks for reading this mind dump of a post, I'm writing while it's fresh but I'm tired AF.6 -
I've spent months with like 200ms+ ping and I just read the Arch wiki for my network card for the first time. Turns out its a common issue that is fixed with one dam kernel parameter. Now my ping is <30ms. Linux just be like that ig.4

The fact that the latest Linux kernel added support for 32 bit systems to function past 2038 is one of the most baffling things I've ever seen in development history... Not saying it's a bad thing... But.... Why3

So I salvaged some computer that was about to be thrown out by IT because it works perfectly fine and would be a waste to lose.
The (current) problem is, there is no built-in wi-fi adapter so I had to order a usb adapter to plug into the machine.
Fortunately enough it supports Linux but cones with a cd with the _source_ of the driver in it and we are supposed to build it. Now what's the problem with that?
First problem: building needs all sorts of build tools, starting from gcc and make. Since it's a fresh install, though, I _cannot_ install those normally because -- you guessed it -- I don't have a WiFi connection, which is why I needed the bloody adapter in the first place, so I spent hours trying to fetch the binaries from the apt register using another computer and bringing them over via USB.
Once that was (more or less) successful, the next problem came around; Second problem: the instructions clearly state to run make, but there is no fucking makefile anywhere so that obviously fails spectacularly. What _is_ there are some bash scripts so I try running those.
Now, just when I think it's finally done (one of the scripts has been running for a while and seems to work) the compiler dies with an error: the fucking driver won't build for the current kernel version. And not just that, but it is clear nobody is using basic things like include guards because gcc kept screaming at me about the same macros being defined over and over due to header file re-inclusion. Like, seriously? Come on!
Long story short the fucking adapter is going back to the seller, let's see if the next one I order more civilized.8 -
whelp. fuck you grub2
fuck you for presneting yourself as a problem to be solved all over again.
fuck you for the efi partition containing a search for the fucking boot/efi partition by uuid
fuck my host system for taking a cloned drive and fucking around because it couldn't tell which drive the uuid was emanating from
fuck them using entries files with linux options specifying the uuid of the root partition which ALSO now must have a subvol parameter supplied to a rootoptions parameter to find the fucking root drive
fuck them for making it look like the fucking software is smarter than it seems.
and fuck them for not creating some kind of autoprobe fucking utility added to teh initial boot drive which is smart enough to load a stub of grub2 and then pull in teh rest of the slice partitions it shouldn't be using in the first place
and fuck you fedora for using btrfs in the first place and mounting a different partition for linux images and yet another under /boot/efi
and fuck you virtualbox for not producing teh shit the kernel finds IMMEDIATELY once in rescue mode !!!7 -
A friend of mine who wants to learn about Linux has a stronger will than me, as I think installing Linux in 2020 is gonna break me but he's still stoked as shit. I'm fucking serious. He asked me to install several distros, in order of interest (because they all fucking failed, because of fucking course they did) on a USB HDD he was using just for this.
We tried, in order:
Arch: initramfs wiped his Windows HDD when it crashed. IDFK how, but it zeroed the top 32KB of the drive. It wasn't even the right HDD...
Linux Mint: nvidia drivers refused to see his GPU after install. No matter what we did. Live media saw it fine until it was installed on the external drive, too.
Debian: Installer couldn't see the external HDD, ever. No matter what we did. It had a /dev entry, lsblk and fdisk saw it, I could format and mount it, but the installer crashed when it refreshed the device list when it was present. Every goddamn time.
Fedora: Installer broke halfway through as an executable (or 70) were corrupted, but the disc matched the ISO and the ISO sums correctly, so this is apparently how it was packed and shipped.
CentOS: Refused to boot. Just entirely. GRUB would go to load the kernel and it'd hang.
All ISOs and discs were verified as matching provided sums using MD5 and SHA256. How the fuck is Linux so fucking hard to get working on older hardware in 2020? Worked great in 2008, worked great in 2018, why is 2020 such a goddamn issue?11 -
I make a mistake today.
The incident happens when I opened my computer, open Vivaldi, and after all tabs are loaded, I update my Linux distro.
Unfortunately, when it updates the kernel, it got lagged, really lagged. My CPU load goes up to 14,56 (which is also the PB of CPU load of my computer). I barely can move my mouse. I decided to Ctrl-C, nothing happened. Then I decided to turn off my computer by pressing the power button once, nothing happened. Then I hold the power button for a few seconds, don't really hesitate or think of anything.
When I start my computer again, it goes to the GRUB. I realized that the GRUB load is slower than usual, but I don't really think of anything. When I choose the 'Alter Linux' option (which is the name of my distro), the GRUB says that it cannot find the kernel and thus it cannot boot. At this point it's pretty fucked up.
2 lessons that I have learned after this incident:
1. Turn off every single other window (except the Update window) when you are going to update.
2. Never turn off the computer while it's still updating, especially if there is kernel update in it.
(Luckily, I have an old version of the distro burned to a Kingston USB, so I can run the live environment of the distro from the USB, and then install another distro to that USB)20 -
sigh. I hope one day Linux can be rewritten in something with more sensible package management. C/C++ can just be a real pain more often that not. My case was trying to install CUDA on ubuntu 16 following the OFFICIAL developer guide. gave up after trying for an hour. It needed the kernel headers for compile the drivers and it was jsut alot of pain dealing with files being in the wrong place and gcc version mismatching and tons of other cryptic errors. and this is for ubuntu which is a pretty mainstream distro.8

Where do i start , if i am interested to contribute to Open Source projects in C ?
I have a good understanding of C language. Even if i am not able to contribute , it would be nice learn from those projects .
The problem with big projects like the linux kernel is that i dont understand or cant comprehend most of the code , except for few sections like gpios..5 -
someone i know well saw that i rolled a couple linux 3ds kernels at one point and said he'd fucking pay me if I made a distro rolled from totally-uncompiled code and a raw kernel and isn't based on any other distro
is this really something people want? i mean fuck I can prolly fill that niche if need be but is that really something there's a demand for???4 -
So I found the reason of kernel panic, my laptop's hdd is fucked, lost all the data. Now using a live usb until I get a replacement. Silver lining is I won't install windows for dual boat and replace elementaryOS with arch linux. I want a proper fight now.1

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 safari7 -
Was running personal laptop on 4.10 kernel (running Manjaro).
Was having problems for some reason with an audio program I'm using and so needed to run some older kernel that is real time for better latency.
Installed that kernel and booted with it.
Attempted to remove kernel 4.10, I don't need it anymore.
Rebooted, some kernel modules aren't loading. Xorg not creating a session.
I have no input working.
Not even wifi.
I can't detect USB devices.
Tried to fix it all night.. going through a ton of forums online...
Finally I give up. I didn't have access to anther computer to get a bootable USB image to. FUCK. IM NOT SMART ENOUFG FOR THIS SHIT.
I have 3 USB drive that I carry around all the time. Why don't I have a live image in one of them?
I went to sleep.
Next day I download Lubuntu (just to boot and backup some stuff before downloading and reinstalling Manjaro).
When I was burning the ISO to the USB, turns out I actually had a bootable Ubuntu on it the whole time.
I feel so stupid.
Last week I don't remember why, but I did sudo chmod 770 /
Which also broke my system.
Took me 3 hours to realize that this was the problem and make it work.
I love Linux. It keeps things interesting..3 -
Tldr; Rust community could definitely be way less annoying, but it's way more annoying listening to everyone bitch about it all the fucking time.
rant()
Tired of the Rust hype? Too fucking bad. Quit complaining that people like well-designed languages more than shitty ones. Yeah, rust devs can be real fucking zealous, but at least the language is good. If you don't like listening to people say "why not rust?" ignore them or ask yourself the same fucking question ahead of time so you don't feel defensive when someone asks it later.
Read some shit about how "it doesn't matter what you build it with if the software is good, its all the same". Ever heard of "right tool for the right job"? Rust has applications all over the place, so people are going to talk about it a lot. Also, just no. Like, Python shouldn't be in the Linux kernel for a lot of reasons, so the tools you choose can constrain whether or not your software is actually "good."
Ever heard of "unsubstantiated trust"? Yeah, you might be good at writing C, but you can get that shit to compile with nasty fucking problems and C's a straight up foot gun in my hands. It's hard to write shitty functioning Rust that does what you say it does, which is less unsubstantiated trust.2 -
Is that me or Lenovo cannot figure out the bios issue I am having with my ideapad-100. The Linux kernel says that the bios has a bug in it and then Windows can't update because the bios has a bug, the bios updater tells me the bios is perfectly fine. This is weird because the laptop is unstable whatever the Os and yeah it did that since I bought it and sent it to be repaired and still the issues goes on

Finally decided to work on my kernel update script a bit (basically I compile the mainline kernel and configure it to slim it down a ton for my laptop, and that gets annoying so I wrote a script to do it for me). As of right now it is functional, it MAY require some babysitting, cause sometimes shit goes wrong, but it hasn't given me any problems the last few times I've run it. But it's also written with Arch in mind (using linux-mainline AUR package), because I use Arch btw. At some point in the future I want to add support for other distros, but I also want to get everything functional on Arch first.
If anyone has any suggestions or anything:

tl;dr Which new laptop + Linux distro combo should I get when seeking for minimal configuration and maintenance hassle?
Hey devRant gang!
I'm looking for a new laptop: which one is supported out-of-the-box by Ubuntu based Linux distros like Elementary OS?
Why Elementary OS you ask? Well, I want to move away from macOS and/but keep the minimal (and pretty) design/interface!
But: I don't want to waste time configuring stuff after install or a kernel update. I don't have time for that: I need to get shit done.
As much as I dislike closed source/evil corporate stuff the fact of the matter is that my MacBook Pro Just Works (and lets me get shit done).3 -
Looks like the full heat of the Linux CoC is finally being felt:

Let me tell you about my wonderful weekend. It all started with a game that doesn't run in wine and it ended up in the biggest nightmare of Windows Update and EFI configuration.
1 - let's boot on my Windows partition to play trackmania 2.
2 - Windows Update interrupts me while driving a track.
3 - Update keep failing over and over again.
4 - I keep trying things to fix Windows Update, but with no success.
5 - Let's try system restore, failed
6 - Let's try to do a reset. "You don't have a recovery drive". Oh, right...
7 - Let's try to upgrade Windows 10 to Windows 10, just because. Nope, "we could not determine if your pc can run Windows 10". Wait what....
8 - I guess I'll be reinstalling this trash. "Nope, can't. Don't like that partition I just formatted". Of course you can't...
9 - Had to delete the partition and let it create new ones. It created a new EFI partition. Just why???
10 - Okay that worked. Let's fix grub now.
11 - Maybe not, let's try rEFInd, because it looks fancy.
12 - After rebooting on the live USB for about 50 times and reconfiguring rEFInd without any luck, I realised the install script didn't install fs drivers for ext4. Oh, right... That's why you didn't find any Linux kernel...
13 - It can't boot windows, they're using a different EFI partition. Let's move rEFInd to the new EFI partition windows created for me.
14 - Finally everything works again. So much effort to play a freaking game without being bothered by windows update. And rEFInd abience theme looks beautiful.
I've got to say though, I learned a lot and the Arch wiki is awesome!6 -
After getting fed up of “being productive” I fooled around on GitHub and had a look at the Stuxnet virus source code which was obtained using a decompiler. Experts who reverse-engineered it found out that it was written in “object-oriented C.” While C is not an object oriented language, anything you can do with classes you can do with structs, static functions, pointers & function pointers. You can see this coding style in the Linux kernel, CPython interpreter and many other places. That was the first indication that a government agency or defence industry was responsible. Amazing stuff !6

So, today, I wanted to try setting up a wireguard VPN server on my little raspberry pi at home. I... expected /some/ issues, but what I found dumbfounded me.
1 - I already had the wireguard package from the unstable branch of the main raspbian repo installed... Huh, okay.
2 - Setting up config was extremely easy... Wow, so the rumors were true. Wireguard really is almost dumb-simple.
3 - Failed to create a network interface? Oh, trouble, here it is! So lets see... modprobe wireguard... Nope. Don't have the module? What?
4 - Reconfigure package to rebuild the module - missing kernel headers? Huh... weird
This was the simple stuff... Then I went down the rabbit hole of the Raspberry Pi ecosystem:
1 - There is the Raspberry Pi Bootloader, that is apparently separate from the Kernel itself. And I didn't seem to have any of the standard linux-image-* installed... What? Weird, yet there I was, running a 4.19.42-v7+ kernel...
2 - No kernel and no headers... What... The... Fuck
3 - Okay, so... Lets just... try to install the latest kernel image then? One apt-get install... It downloaded the image, but during package configuration, it failed because... I didn't have... its headers? What? What for? And if it needs them (for whatever reason), why isn't the headers package as a dependency? Ugh, whatever...
4 - Another apt-get install and... Okay, building the initrd image aaaaand...
FAIL
WHAT. What is it this time!?
Oh... Ran... No more space on device? What? Is /boot independent? Of course it is, it has to be, its a bloody different filesystem
Okay, so, lets che-OH MY GOD WTF.
Its just bloody 45 MBs big! The entire /boot is just 45 MBs large. WHY. THE. FUCK.
This was a default raspbian install from I have no idea when. But... Why. Oh WHY would ANYONE pre-configure /boot to be this incredibly tiny!?
No wonder the new init ramdisk couldn't fit in there! Its already used up from 64%!
Thanks, Raspbian Devs, now I gotta reinstall the whole system because, yes, the /boot is, of course, sector 8192. Just far enough from 2048 that there are *some* sectors free - About 3 MBs.
So what did I try? Remove the partition and recreate it from the very beginning. Only... I never tried in in the past, and okay, kernel doesn't like having the partition where its image resides deleted on the fly, it will not give up FDs pointing there or something.
So now, I have a system I cannot reboot, or it will never boot back up :|
Thanks, Raspbian!
I need to get a cheap 1U somewhere or something T.T1 -
A colleague of mine has built a kernel module that is part of our system. He wrote it for Linux 4.4 but in the meantime our servers got updated to 4.15. The kernel API changed from 4.4 to 4.15 so the module does not build anymore. He said he will update it, but in the mean time I figured it would be easiest to just use 4.4 in the meantime. I downloaded the kernel deb package and installed it. Now, after reboot I can't ssh into the machine any more. I just started this project and I'm already tired of it. Every time I fix something a new issue appears. And I did not even start what I am supposed to do1

Currently trying to make a multi boot machine, with a lot of linux distros inside, like debian, fedora, gentoo and arch.
I know I will have to format everything a lot of time, because of stupid mistakes, I want to try to put /home in common, and play with some more SSD, and to put a preempt_rt patched kernel somewhere.
I am starting from debian,
Format counter: 3
Reason 0: because i need to install at least once...
Reason 1: I am stupid
Reason 2: I disconnected the SSD,to connect a disk with windows. Now bootloader doesn't find any os in the SSD anymore... still no clue, and in case of doubt: give windows the fault 😠😠😠
DAMN YOU WINDOWS, how did you find that I want to use debian? What did you do to break it?? (Despite it wasn't even connected?!?)
I have checked everything about secure boot, and I am sure it is disabled...
And every search online gives results about dual boot, but it is not my case... :/ -
My mind is not stable.
Office work requires - Linux Internals (knowledge on kernel, Device Drivers, Yocto etc) & Networking ( security ) -> CR on C/C++
Office work also requires - Python for tool development
My personal project requires - NodeJs, React
And I also want to appear for Interviews so also require DS & Algorithm
I hope you don't judge me3 -
Just finished building a new Linux workstation that my company bought me! That Ryzen 2700X is just ridiculously fast! I'm not talking about irrelevant FPS benchmarks on some hip game...
I'm talking about compile time for the Linux kernel and buildroot!
Long story short, is about 5x my previous workstation with a Xeon 3.
Now I wanna get my hands on a 32 threadripper for my personal computer!! -
If I was to create a movie in which there should be a scene with a hacker in front of his computer, I'd never hire professional designers and animators to create fancy videos that can be played back on the computer said hacker is working on. Instead, I'd just run make on the Linux kernel, unplug the keyboard and let the actor hit it as fast as he can. Should look professional enough.1

I hate interviewing with these FAANG or FAACK companies. I just finished 3 rounds of mind torturing coding sessions involving some obscure algorithms that I was expected to come up with on the fly! Thinking that the hard part is over and next is the behavioral round, I just received an email from the recruiter telling me that the next round is some obscure Linux kernel internals I need to be ready for.
How do people get jobs at these companies?!!!7 -
now i know this is devrant and not su-rant or sysadminrant or anything alike,
but it cringes me everytime i see rants like "linux this" or "linux that".
now those who does it, do understand that the term "linux" refer to the kernel and not the os in it's entirety, right?6 -
Linux needs a KBI. That driver recompilation thing when upgrading a minor kernel version is so annoying. Solaris, HP-UX, AIX, BSDs had already solved this in the early 2000s.2

Okay, so because my desktop has an APU (AMD A8-3850) and a dedicated GPU (AMD R9 380) in it, and i'm finally getting a (small, probably 240GB because budget) SSD for it, what Linux distro should I use? I'm planning on doing libvirt passthrough for Windows using my APU because fuck running it as a main anymore, it breaks too often. As far as I can tell, my options are as such, family-wise:
- Debian kernel: amdgpu doesn't like that I have an APU and GPU and refuses to see a screen (yes, even after all the Xorg configs and xrandr bullshit and kernel flags and...)
- RHEL: a lot of Red Hat-based distros (mainly Fedora) have packages that are broken out-of-repo and out-of-box recently, but maybe it'll like my hardware? (It's been a few Fedora releases since I last tried it, is this fixed? CentOS has such old packages that it's not even worth bothering with for my needs.)
- Arch kernel: go fuck yourself, i don't wanna take 1000 hours to get it running for a week, nor would the updates be any better than Windows' current problem (or even more so, as slightly more often than not Windows' broken updates just add annoyances and don't hose the system.)
did I miss any?25 -
New Year's goal: find out if linux vulkan/mesa drivers work on my desktop as there's no real reason to not switch now other than maybe that.
Proton, DXVK and Gallium Nine support like 80% of games now (suck it, nvidia users, we get the good ones!) and i've seen performance improvements after switching from Windows builds on Windows to Windows builds on Proton using the same hardware.
Question is: how the hell do I carry over almost 2TB of shit to the new partitions? Also, Virtualbox is a bitch on Linux as if my kernel updates it's fucked and Boxes is trash...11 -
Ubuntu 🤬
only releasing amd64 image !! , supporting an instruction set architecture does not mean code is optimised for other microarchitecture
i thought linux distributions are do less and do way better than others, so why so much bloatware!!!.
ideally best way is to compile your own kernel and add minimal gui support as required, too much work !!!
also just a heads-up if you are using Catalina use virtual-box 6.0.22
also vivado 2019.2 is suable with ubuntu 18.04 + lightdm , remove that gnome shit15 -
Who the fuck thought it is a good idea to disable i2c_hid module in Linux kernel 5.12 by default?
I compiled the kernel 3 times and was wondering why is my touchpad not working...5 -
Fucken great.
Managed to "finish reparing" my second Razer blade 14, swamped around some ssds and now both don't boot from my ssd.
So, I just disabled my mobile workstation.
Great.
3 days twiddling with it later and I still haven't managed to boot it.
Linux from a usb boots fine, Linux from the ssd, nope, no chance.
Csm looks good,
Bios sees the drive, should be good.
But I can only boot it legacy, which goes nowhere.
No uefi mode for the SSD.
But it worked before, so what the heck.
So when I boot grub of a usb stick, the live image runs fine.
I can also boot the ssd with the usb grub.
Most craziest thing for me right now is, I now have an nvme in the blade, but the blade doesn't fully support nvme as boot device.
And the external grub can boot it, and it seems to work properly once grub and the kernel take over, has full "support".
Just a side note, the other drive is a sata m.2 that worked fully before so i still have no reason why it isn't working.
So I thought I could now use a usb stick with grub to boot the nvme.
But nope, can't boot the usb stick anymore.
What the fuck is going on?!
And for all those realising that the nvme will not be running at pcie 3.0 by 4, yes, but it's not a high-end drive, Samsung pm951 so that doesn't matter. -
Today I had a look at the Linux kernel on GitHub. There was a commit made by someone else which I tried to comment on. But my comment was not getting added— probably because it is not my PR. Is this a feature or a bug ?10
-
Fucking Apples hold my bananas! Collegue and me see our naïve thought refuted that a commercial vendor, most valuable company would create an OS that is not as split and fucked up as Linux distros.
It is hard even where to begin, so deep is the shitfest they are putting developers through with Mojave and Catalina.
Our testers weren't hardly able to install Catalina beta 6-7. Behavior of kernel extension and full disk access varying on a daily basis. Fixing these bugs is like nailing a pudding to the wall.
Makes me wanna quit software. Whom should you trust if even your OS is flaky as hell?8 -
Has anyone spidered the web and repos and found info about the Linux distros for comparison ? Like packages and vendor support and kernel ? I feel like fedora is just debian with newer software that uses rpm
On another note I'm wishing these idiots had just let me work straight through as a developer or tax auditor etc because I'm not working in Dickson just so they can steal my car again after working hard and honestly to improve my fucking situation
As I said as I remember things and that was a pretty big one
All the time people spent fucking around and the world went in a circle and I said this last time
Fucking people should have to hand me over a check for the number of times I bought that damn car !2 -
So, despite being pretty experienced with Linux server management, today, I failed, even after hours spent tinkering, to get Bumblebee working on an older laptop of mine (Intel i3 + Geforce 960m).
What's funnier is that before I wiped that laptop with a clean install, it was working, albeit it on an out of date kernel / driver combo.
Though curiously, despite using the newest release of Xubuntu, the Bumblebee PPA repo wasn't signed (Missing InRelease file), and further lacked one of the Package index files (For i386 i believe)
I'm about to sell the laptop tomorrow. Anyone has any hints or things I could have missed? I still have a day to work on it, and if I don't manage, I'll just put on a clean win install...4 -
I think I finally reached a point where I Have to completely reinstall my RPi.
Running Raspbian, I was under the impression their kernel releases worked the same way a pure Debian release worked - That the kernel was somewhere in the system repository.
Turns out it was, but in a different pool. And also turns out the new kernel and initramfs won't fit into my /boot as, for some reason, it is under 50 MBs in size. I dunno why, but I don't have any unallocated space left to grow the partition...
I have no idea why the boot is so small (Probably because, when I was setting the system up, I wasn't really that good with Linux yet, and just went with defaults).
What do you guys think - Is it better to run the native Raspbian system (Formerly RaspberryPi OS), or go with a pureblood Debian for Arm? (Yes, I already checked, my HW revision [3B+] is already compatible])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.
