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 -

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 -
"Can't we extract the UNIX from Linux and use it as our server operating system?"
fml
Linux isn't even based on UNIX, but this piece of shit of a bitch of client was so freaking stubborn, and wanted a RAR file of UNIX from me7 -
Real Linux fuck up coming up.
Be me.
Working on a project.
Accidentally used sudo with git pull, every file now is only accessible for root users.
Thinking to myself.. okay I'll just do chmod 777 to the current directory
Forgot how to use chmod
At first something like
Sudo chmod ./ 777
Not working
Maybe
Sudo chmod / 777
Not working
Remembering that it's the other way around
sudo chmod 777 /
Now... I fucked up. I forgot the dot, and for a sec I forgot that '/' means root directory and not current like './' does.
Few moments later the permission system of Ubuntu is utterly fucked. Everything is not working.
Need sudo in order to fix everything but sudo isn't working.
Few hours of crying later,I solved it thanks to some nice ppl online helping stupid people like me who used that command...😂10 -
Windows troubleshooting:
- Works on my system, therefore it's not an issue.
- Must be a hardware error.
- Obviously it's just cheap hardware.
- Have you tried turning it off and on again?
- Here's some obscure error code that leads nowhere.
- Have you tried "sfc /scannow"?
AS IF SFC IS A FUCKING SILVER BULLET!!!
- Our Indian support chap from answers.microsoft.com will help you.
RRRREEEEEEEEEEEEE!!!!!!!
Solution: quietly weep and reinstall your system.
Linux troubleshooting:
- There are good quality log files.
- You can run the program from the command-line and read both stdout and stderr from it.
- You can usually run the program with high verbosity options to help you track down the error.
- Even daemons can have their commands spawned from a dedicated shell, to see why they failed.
- Usually it's a configuration error and you can easily edit the configuration file.
- More often than not, the program will tell you why it failed.
Solution: usually easy to find.
I fucking love Windows. Because you know, it's so easy to troubleshoot and the support is so great!!!2 -
I've found and fixed any kind of "bad bug" I can think of over my career from allowing negative financial transfers to weird platform specific behaviour, here are a few of the more interesting ones that come to mind...
#1 - Most expensive lesson learned
Almost 10 years ago (while learning to code) I wrote a loyalty card system that ended up going national. Fast forward 2 years and by some miracle the system still worked and had services running on 500+ POS servers in large retail stores uploading thousands of transactions each second - due to this increased traffic to stay ahead of any trouble we decided to add a loadbalancer to our backend.
This was simply a matter of re-assigning the IP and would cause 10-15 minutes of downtime (for the first time ever), we made the switch and everything seemed perfect. Too perfect...
After 10 minutes every phone in the office started going beserk - calls where coming in about store servers irreparably crashing all over the country taking all the tills offline and forcing them to close doors midday. It was bad and we couldn't conceive how it could possibly be us or our software to blame.
Turns out we made the local service write any web service errors to a log file upon failure for debugging purposes before retrying - a perfectly sensible thing to do if I hadn't forgotten to check the size of or clear the log file. In about 15 minutes of downtime each stores error log proceeded to grow and consume every available byte of HD space before crashing windows.
#2 - Hardest to find
This was a true "Nessie" bug.. We had a single codebase powering a few hundred sites. Every now and then at some point the web server would spontaneously die and vommit a bunch of sql statements and sensitive data back to the user causing huge concern but I could never remotely replicate the behaviour - until 4 years later it happened to one of our support staff and I could pull out their network & session info.
Turns out years back when the server was first setup each domain was added as an individual "Site" on IIS but shared the same root directory and hence the same session path. It would have remained unnoticed if we had not grown but as our traffic increased ever so often 2 users of different sites would end up sharing a session id causing the server to promptly implode on itself.
#3 - Most elegant fix
Same bastard IIS server as #2. Codebase was the most unsecure unstable travesty I've ever worked with - sql injection vuns in EVERY URL, sql statements stored in COOKIES... this thing was irreparably fucked up but had to stay online until it could be replaced. Basically every other day it got hit by bots ended up sending bluepill spam or mining shitcoin and I would simply delete the instance and recreate it in a semi un-compromised state which was an acceptable solution for the business for uptime... until we we're DDOS'ed for 5 days straight.
My hands were tied and there was no way to mitigate it except for stopping individual sites as they came under attack and starting them after it subsided... (for some reason they seemed to be targeting by domain instead of ip). After 3 days of doing this manually I was given the go ahead to use any resources necessary to make it stop and especially since it was IIS6 I had no fucking clue where to start.
So I stuck to what I knew and deployed a $5 vm running an Nginx reverse proxy with heavy caching and rate limiting linked to a custom fail2ban plugin in in front of the insecure server. The attacks died instantly, the server sped up 10x and was never compromised by bots again (presumably since they got back a linux user agent). To this day I marvel at this miracle $5 fix.1 -
*edits file on remote server*
WanBLowS: naah you can't 😈
*le wild BSOD appears for the over 9000-th time*
... Yeah. Windows, great job. Who needs system integrity when they're working on remote servers anyway, right?!
And to top it all off, le reboot mentions that they're working on fucking "features" again. That's what you needed to BSOD for?! For a goddamn motherfucking feature?!! Fucking piece of shit.
At least when I opened vim on that server again, it's saved everything neatly in the .swp files, ready for recovery. Now that's neat, isn't it? Microsoft, the Linux community has already moved on to nvim in terms of development, but maybe, just maybe, you can learn a thing or two from our "legacy software", vim.
As for me, maybe it's time to take out my Arch laptop again. At least that won't crap out on me because the sun and the stars are in a position that the OS doesn't like, or something stupid like that. FUCK YOU MICROSHIT!!!11 -
Day #01 of my brother's switch to Linux:
So far so good, he's really happy with the Linux (surprisingly). The Witcher 3, Payday 2, Minecraft run flawlessly, although I had to make some small configurations in disk mounting, because of the fact that the games disk is still in NTFS file system4 -
I've never used Windows in my day-to-day life. No kidding.
When I got my father's first computer, I used an old distribution called BBC Linux. I didn't have any computer knowledge, it was my first contact with a computer, so I went to a friend's house and asked for a CD to install on my computer. I don't know if this friend ended up making a "gotcha" and thought I'd give up, but I just read the manuals and fell in love. That was year 2000.
Then I used Conectiva Linux, then I went to Red Hat 9, then Slackware, then in 2007 I started using Solaris. And I stayed on Solaris (Solaris 10, Solaris Nevada and OpenSolaris) until 2011.
In 2011 I bought a Mac. I stayed at Apple until 2020, when I couldn't stand Apple forcing me to buy new computers (I still don't understand how a 2011 iMac, i5 (4 Hyper Thread cores) with 16GB of RAM, 1TB SSD only runs up to High Sierra).
Then I bought a Dell. It came with Windows 10, the first thing I did was install WSL2. I could not stand it, the system is bad, sorry. I installed OpenSuse and have been using it for two years.
It's just that every day someone tells me "how can you use this"? "There is no alternative to Windows, do you want to be different?"
I know that my story was the reverse of the "mainstream", so I'm going to talk about my vision of Windows, that in my brain it is actually the "alternative".
- Having a file explorer without "tabs" in 2022 is unthinkable for me.
- I love terminal. And the Windows terminal is very limited. "ps ... | awk ... | xargs ..." is a must for me. "find ./ -name '...' -exec ..."... these things on Windows are totally "different" and have the "powershell way" while all other operating systems keep the same form. And cygwin is not an option. As Wine for serious work is also not.
- Dragging a file into the terminal, and having it write its path, is so natural, that when Windows didn't do it, I was dismayed.
- I've always used StarOffice, OpenOffice and now LibreOffice. All the people in my story received my documents and reports as a PDF and no one complained. Until a coworker saw me editing in LibreOffice and said "oh I want it in word format". As long as he didn't know, everything was fine, right?
- Windows is paid. And is there advertising? I don't understand. And I refuse. If you want to display advertising, then excuse me. I have no problem paying, I'm not an opensource shiite. It's just that paying and not working bothers me much more than an opensource that I can fix or expect a fix knowing the good will of the people involved.
- Hyper-V is a joke. QEMU/KVM is better, and Bhyve on FreeBSD which is a very young project, is already a million times better than Hyper-V.
- Developing in C/C++ for Windows is only possible in two ways: Either you've always lived in Windows and your brain is conditioned, or you compile with MSYS2 (CLang or GCC).
- There is no significant evolution of the windows desktop since 95.
- Multiple workspace support with multiple monitors, not ready. It's another joke.
- REGEDIT does not need any comment.
- The system loses performance over time. I still don't know how Windows achieves this.
- I've seen people complain about desktop fragmentation on Unix and Linux. Many DEs end up leaving applications with different themes (like running a Qt application in Gnome and GTK in KDE), but to be quite honest, the lack of Windows standard bothered me much more. Even Microsoft's own software is completely different: Control Panel, Calculator, Paint and Office, To-Do, and Settings, have horrible style differences and look-and-feel fragmentation.
- Dark mode has not been implemented. It's another joke. Many applications are white while everything else is dark. Sorry, even on Linux which is a mess, this has been resolved. And well resolved.
- NTFS? Serious?
- C:, D:.. It doesn't convince me since DOS.
- Bloatware.
- News "biased" in the search bar is a lack of respect for those who use the computer to work.
And that. For me, Windows is the alternative operating system. I can't take Windows seriously, for me it's an experimental one like Haiku or ReactOS. It's good to play.
About market share, it doesn't convince me to use it. But convinces me to sell. I've always developed applications to run on Windows. And when I need it, I turn on a VM to compile the project. But in everyday life? Impractical.15 -
I used to use WinBtrfs on Windows to get away from the clusterfuck that is NTFS on my WD Elements. But today I figured.. why? Why not just mount the drives to my file server already? I mean even over a USB 2.0 link, a USB 3.0 drive will perform decently. Not as good as my RAID-0 array there for sure, but still. So, that's it.. fuck it. Done with trying to get WanBLowS to adapt to my needs. Decent drives for a decent operating system, all the 10TB straight to my file server!! Then WanBLowS can go jerk itself in its clusterfuck of NTFS and SMB shit, while the actual grunt work is done by something that's at least reliable and won't shit itself - Linux. As it should be done!!! Trying to get WanBLowS to manage something more important than browsing the Phasebuk, what was I even thinking?!17

So turns out getting drunk and installing arch Linux was a bad idea, somehow managed to format the installation USB instead of my secondary hardrive, set my home directory as the root file system and somehow managed to half install the needed packages to the USB so I wasn't booting and had to go back to a fresh windows install just to redo the USB...
Don't drink and Linux kids...2 -
So I'm writing some multithreaded shit in C that is supposed to work cross-platform. MingW has Posix threads for Windows, so that saved already half of the platform dependency. The other half was that these threads need to run external programs.
Well, there's system(), right? Uhm yes, but it sucks. It's incredibly slow on Windows, and it looks like you can have only one system() call ongoing at the same time. Which kinda defeats the multithreaded driver. Ok, but there's CreateProcessA(), and that doesn't suck.
Fine, now for Linux. The fork/exec hack is quite ugly, but it works and is even fast. Just never use fork() without immediate exec(). First try under Cygwin... crap I fork bombed my system! What is this shit? Ah I fucked up the path names so that the external executable couldn't be run.
Lesson learnt: put an exit() right after the exec() in the path for child process. Should never be reached, but if it goes there, the exit() at least prevents a fork bomb.
Well yeah, sort of works under Cygwin, but only with up to 3 threads. Beyond that, it seems like fork() at some point gives two processes the same PID, and then shit hangs.
Even slapping a mutex around the fork and releasing it only in the parent process didn't help. Fork in Cygwin is like a fork in the ass. posix_spawn() should work better because it can be mapped more easily to the Windows model, but still no dice.
OK, testing under real Linux. Yeah, no issues with that one! But instead, I get some obscure "free(): invalid size" abort. What the fuck would that even mean?! Checking my free() calls: all fine.
Time to fire up GDB in the terminal! Put a catch on the abort signal, mh got just hex data. Shit I forgot to compile with -O0 and -g. Next try. Backtrace shows the full call trace, back to the originating line in my program - which is fclose() on a file.
Ahhh I remember! Under Linux, fclosing a file that is already closed makes the program crash. So probably I was closing it twice. Checking back.. yeah that's where it was.
Shit runs fast on several cores now!8 -
Supervisor has me making a web app in this badass new stack called the LAP (linux, apache, php) stack because he would he would like the app to be "simple". He's spot on though.. having a three letter acronym saves so much time.... and then we don't need to worry about a database... or querying.... or efficiency.... or even the web app itself because clearly he expects the fucking code gods to come down and turn this piece of shit web app into a fucking masterpiece if he thinks this shit can be done based on a hacked together file management system. Please save me code gods4

OBS is advertised as the expert's screen recording and streaming tool, every list on the internet makes it out to be some incredibly difficult program not recommended for newbies.
It's also the only linux screen recorder that works out of the box on Pipewire, records both microphone and system sounds and all configuration was to
1. select recording as my main use case in the setup wizard which is a very verbose English popup, then accept all defaults
2. add a new source, following the instructions written in the box which are also the only instructions on screen after application launch
3. set the output directory (optional) by going to File > Settings > Output > Recording Path, all of which were the first items I guessed. If I had not done this, it would've written everything to my home folder which is a bit dumb but not confusing at all
4. click Start Recording
5. click Stop Recording when done
Some newbie-oriented screen recorders have a more complicated setup procedure than this super advanced experts' tool don't touch without safety gloves and a degree in video engineering.11 -
I am a Windows person. I always argue how great it is.
Well, not today.
I was today years old when I learned that you CANNOT uninstall store app via store ;p You need to go to settings / apps and functionality / your app / uninstall
The photo app (Yes the one bundled with win10) doesn't work if you use Hard drive compression AND it is a symlink for OneDrive (So you don't need to keep all photos on the drive). Fucking Paint works without problems.
Email client : If you alt+tab too fast after hitting 'Send email", there is 50% chances that email won't be send. Basiclly you need to hit "send" and wait until you see it in "sent" folder.
Well, as i'm ranting, here for Linux too :
I have a small ubuntu server VM, worked very well for last 6 months. Now "System in read only mode". Fucking apt-get upgrade fucked with something. I don't want to look, so I'll just rebuild a fresh vm.
And macOS should take sometyhing too : Who the fuck decided "enter" is for editing the name of file ?! really !
Well, ALL os are shit, all have downsides, I need my own OS. But I still want AA games... So windows for me.25 -
When you're developing it's very well advised to run your software locally in an environment as much as possible matching the real environment.
So for example, if you're running linux on production then you also run it locally to run your code.
Here's where people need to shut the fuck up:
No, mac is not good for linux development. Not unless portability is already a concern that you have and even then it might be counter productive. So many times when people say this, portability isn't not a concern. What runs on servers is up to them.
If your servers are going to be centos, then you develop with centos. Not with debian, gentoo, ubuntu, maxosx, etc.
Even different linux distros are a headache for portability when it's just to support a few desktops for development so don't think that macosx is going to cut it. It might not be as radical a difference as between windows and linux traditionally is but it's still not good for "linux" development. I don't think people making that statement really know what linux is now how different distributions work.
What you use for your graphical operating system doesn't matter to much but when you run your code then there's a simple solution.
Another thing people need to shut up about. It's not docker, unless you're already in Linux where docker is one of many options such as chroot or lxc.
This question always comes up, how do you developer for linux in windows? No it's not docker it's virtual machine.
It's that simple. You download the ISO for the distro you want and then install it on a VM. What does docker for windows do? It runs a linux VM that runs docker.
This may come as a great shock to developers around the world but it is possible to run linux in a VM and then any linux application your want including docker.
Another option is to shove a box in the corner, install what you need on it, share the file system and have people use that to run their code. It really is that easy.6 -
Suicide Linux:
You know how sometimes if you mistype a filename in Bash, it corrects your spelling and runs the command anyway? Such as when changing directory, or opening a file.
I have invented Suicide Linux. Any time - any time - you type any remotely incorrect command, the interpreter creatively resolves it into rm -rf / and wipes your hard drive.
It's a game. Like walking a tightrope. You have to see how long you can continue to use the operating system before losing all your data.
Please install: https://qntm.org/suicide9 -
So recently I installed Windows 7 on my thiccpad to get Hyperdimension Neptunia to run (yes 50GB wasted just to run a game)... And boy did I love the experience.
ThinkPads are business hardware, remember that. And it's been booting Debian rock solid since.. pretty much forever. There are no hardware issues here. Just saying.
With that out of the way I flashed Windows 7 Ultimate on a USB stick and attempted to boot it... Oh yay, first hurdle to overcome. It can't boot in UEFI mode. Move on Debian, you too shall boot in BIOS mode now! But okay, whatever right. So I set it to BIOS mode and shuffled Debian's partitions around a bit to be left with 3 partitions where Windows could stick in one more.
Installed, it asks for activation. Now my ThinkPad comes with a Windows 7 Pro license key, so fuck it let's just use that and Windows will be able to disable the features that are only available for Ultimate users, right? How convenient would that be, to have one ISO for all the half a dozen editions that each Windows release has? And have the system just disable (or since we're in the installer anyway, not install them in the first place) features depending on what key you used? Haha no, this is Microsoft! Developers developers developers DEVELOPERS!!! Oh and Zune, if anyone remembers that clusterfuck. Crackhead Microsoft.
But okay whatever, no activation then and I'll just fetch Windows Loader from my webserver afterwards to keygen my way through. Too bad you didn't accept that key Microsoft! Wouldn't that have been nice.
So finally booted into the installed system now, and behold finally we find something nice! Apparently Windows 7 Enterprise and Ultimate offer a native NFS driver. That's awesome! That way I don't have to adjust my file server at all. Just some fuckery with registry keys to get the UID and GID correct, but I'll forgive it for that. It's not exactly "native" to Windows after all. The fact that it even has a built-in driver for it is something I found pretty neat already.
Fast-forward a few hours and it's time to Re Boot.. drivers from Lenovo that required reboots and whatnot. Fire the system back up, and low and behold the network drive doesn't mount anymore. I've read that this is apparently due to Windows (not always but often) mounting the network drive before the network comes up. Absolutely brilliant! Move out shitstaind, have you seen this beauty of an init Mr. Poet?
But fuck it we can mount that manually after every single boot.. you know, convenient like that. C O P E.
With it now manually mounted, let's watch a movie! I've recently seen Pyro's review on The Platform and I absolutely loved it. The movie itself is quite good too. Open the directory on my file server and.. oh. Windows.. you just put db.thumb on it and db.thumb:encryptable. I shit you not, with the colon and everything. I thought that file names couldn't contain colons Windows! I thought that was illegal in NTFS. Why you doing this in NFS mate? And "encryptable", am I already infected with ransomware??? If it wasn't for the fact that that could also be disabled with something as easy as a registry key, I would've thought I contracted ransomware!
Oh and sound to go with that video, let's pair up some Bluetooth headphones with that Bluetooth driver I installed earlier! Except.. haha nope. Apparently you don't get that either.
Right so let's just navigate the system in its Aero glory... Gonna need to flick the mouse for that. Except it's excruciatingly slow, even the fastest speed is slower than what I'm used to on Linux.. and it's jerky as hell (Linux doesn't have any of that at higher speed). But hey it can compensate for that! Except that slows down the mouse even more. And occasionally the mouse driver gets fucked up too. Wanna scroll on Telegram messages in a chat where you're admin? Well fuck you mate, let me select all these messages for you and auto scroll at supersonic speeds! And God forbid that you press delete with that admin access of yours. Oh maybe I'll do it for you, helpful OS I am!
And the most saddening part of it all? I'd argue that Windows 7 is the best operating system that Microsoft ever released. Yeah. That's the best they could come up with. But at least it plays le games!11 -
Tried to dual boot Arch with Windows yesterday.
Everything was going smoothly. Shrunk the C: partition, ran the installer, installed the OS fine. But it was still booting straight to Windows.
So I edited the BCD to point to Grub instead of Wilndows. Then the plan was to boot into Arch, find Windows, and add it to Grub, problem solved.
Wrong. I had forgotten to disable secure boot. Arch and Grub were booting in BIOS mode, but Windows was UEFI. Grub couldn't boot or even see Windows.
So now I was stuck with just Arch. So I flashed a Windows drive, booted from that, automatic startup repair failed. Opened up the command prompt, tried to rebuild the BCD from there. Surely I can just rebuild it and forget about trying to dual boot right? I just want to get back to being able to use my PC.
Wrong again. Didn't find Windows. Had to get rid of the BCD file before I could rebuild it, but couldn't find it. Found out that I could use diskpart to mount the system partition and assign it a drive letter, renamed the BCD, rebuilt it, and finally was able to reboot into Windows.
Learn from my arrogance. First time Linux users should not attempt to install Arch, let alone do it alongside Windows on the same disk.4 -
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 -
macOS fuckup continued. Today I used a camelcase name for some new file and a directory. Later I didn't like it and wanted to change to lowercase. Pushed it to bitbucket: now I had both versions! Hold my goji berries, what's going on? Maybe some git config screw up? After a bit of fiddling I remembered an old Linus' rant on Apple's file system when they wanted to adopt case insensitivity. So wait, did they actually do that shit? I thought I was on a unixoid, bastardized BSDish system, that apart from all the oddities that Apple bestowed on it, that there was still some sanity left... But, no there isn't. AFP really defaults to case insensitivity.
I have no words.
So switched to my Debian, where I resolved the duplication in two secs. Now Linux feels even much more comfy and home.29 -
I was once asked to create a fully secure chat system prototype (the ui didn't matter) in 2 days. We ended up building a client in python (which I wrote) and it kinda worked and a c# backend that didn't really work.
1 hour before we had to present the project to some high up management we decided that we couldn't fix the bugs in the system.
So I came up with a cool idea. Why not use ssh?
So I set up a bash script that writes to a file and tail -f that reads from the file. That way you could chat securely with another person.
I made it 15 minutes before the presentation with no Internet working :) they said it was hacky but a cool solution they saw that day :p I felt happy and that I had to thank Linux for being there for me2 -
Linux software RAID and LVM are pretty powerful.
Bought a new server case for my home file server / VM host. 3U with 16 hotswap bays. Had 2x software RAID1 mirrors already with everything on them. Inserted 2 new disks with system running. Created new RAID10 array using these, with their mirrors as "missing".
Created new physical volume. Extended volume group into it, then used pvmove to transfer every logical volume across. Shrunk volume group to no longer use the old RAID1 array, disassembled that array, added its disks to the new array... Now just waiting for the mirror disks to sync up.
All this, with the system and several VMs still running.
And with a backup, of course ;)3 -
I continue to internally read and study about Smalltalk in an effort to see where we might have FUCKED UP and went backwards in terms of software engineering since I do not believe that complex source code based languages are the solution.
So I have Pharo. Nothin to complex really, everything is an object, yet, you do have room for building DSL's inside of it over a simple object model with no issue, the system browser can be opened across multiple screens (morph windows inside of a smalltalk system) for which you can edit you code in composable blocks with no issues. Blocks being a particular part of the language (think Ruby in more modern features) give ample room for functional programming. Thus far we have FP and OO (the original mind you) styles out in the open for development.
Your main code can be executed and instantly ALTER the live environment of a program as it is running, if what you are trying to do is stupid it won't affect the live instance, live programming is ahead of its time, and impressive, considering how old Smalltalk is. GUI applications can be given headless (this is also old in terms of how this shit was first distributed) So I can go ahead and package the virtual machine with the entire application into a folder, and distribute it agains't an organization "but why!!!! that package is 80+ mbs!") yeah cuz it carries the entire virtual machine, but go ahead and give it to the Mac user, or the Linux user, it will run, natively once it is clicked.
Server side applications run in similar fashion to php, in terms of lifecycles of request and how session storage is handled, this to me is interesting, no additional runtimes, drop it on a server, configure it properly and off you go, but this is common on other languages so really not that much of a point.
BUT if over a network a user is using your application and you change it and send that change over the network then the the change is damn near instant and fault tolerant due to the nature of the language.
Honestly, I don't know what went wrong or why we are not bringing this shit to the masses, the language was built for fucking kids, it was the first "y'all too stupid to get it, so here is simple" engine and we still said "nah fuck it, unlimited file system based programs, horrible build engines and {}; all over the place"
I am now writing a large budget managing application in Pharo Smalltalk which I want to go ahead and put to test soon at my institution. I do not have any issues thus far, other than my documentation help is literally "read the source code of the package system" which is easy as shit since it is already included inside. My scripts are small, my class hierarchies cover on themselves AND testing is part of the system. I honestly see no faults other than "well....fuck you I like opening vim and editing 300000000 files"
And honestly that is fine, my questions are: why is a paradigm that fits procedural, functional and OBVIOUSLY OO while including an all encompassing IDE NOT more famous, SELECTION is fine and other languages are a better fit, but why is such environment not more famous?9 -
Gamemaker studio 2's 2019 roadmap just got released.. Still no Linux IDE (FFS) but it only took them how many years to realise that not every developer is a malicious cunt and give us the ability to disable to sandbox file system?!
I swear they add and change stuff that is so trivial instead of focusing on the engines major problems and absent features, eg. Can't use SVG graphics, the need to be exported in flash (SWF) because you know, makes sense?

I fucked up. I used the shebang line #!/usr/bin/env python3 in a script that was being ran every 5 minutes with a cron job. This generated an email to a system that dropped a file for processing and sent an age email for each file every minute. Because the Linux OS generated emails didn’t contain a keyword the script closed by design but I forgot to uncomment the delete temp file line. This started on Wednesday before a 4 day weekend. By the time I got in on Monday I was 40GB over my email quota and receiving 2500 emails a minute. I fixed the script and stopped the emails but down I have to clear out those emails. Here it is Wednesday and I am deleting 1 MB every 3 seconds. This is painful.

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 -
Warning long rambling story cause sleep deprivation
I never really bothered with ssh outside of using putty to remote into my servers and rpi's from my desktop to run updates, install something, or whatever else.
But today I was on a call with my cousin bored cause she was just rambling, so I opened vscode to clean my install of unnecessary extensions I installed and haven't used more than once or twice.
I saw Remote - SSH and as I was bored listening to a teenager complain about high school just like I used to (lol) and responding when she asked me something. I scrolled through the page, then the documentation just casually skimming the text
I setup an ssh key on an rpi I threw manjaro arm following the instructions on their tips and tricks page
I then moved the key to my desktop using winscp (cause lazy)
leading to having a minor hicup of rsa not being an accepted keytype (thanks 'your favorite search engine' for the help)
Finally, I was able to connect using the private key
at this point my cousin went to bed cause she has school tomorrow. But I was still doing stuff with ssh, I created a new ssh connection in VSCode, but had to go to the documentation to figure out how to make it use my fancy new key file, not hard took 30 seconds of looking to get it working.
Now that I was in, I moved to my development folder, created a folder for PiHole, created a compose yml, created a pihole-data folder.
I opened the yml and pasted in a compose from dockerhub.
at this point I thought 'i can't just run this from terminal can I'. and Obviously it worked cause there's literally no reason it wouldn't I'm just stupid to think it might not.
So I created folders and files on a remote system, launched a docker container, checked for package updates after on a linux machine. All from VS-Code on a windows machine.
I know this is simple for some people, i know some people are like 'where's the interesting part'. but ehhh I thought it was cool to get it setup, I now really regret not getting into ssh sooner, and I'm definitely going to uninstall vscode on all my smaller graphical VM's in favor of doing this. and this will definitely help with my headless vm's.
I also will have to thank my cousin, might not have done this if I wasn't stuck at my computer on messenger call with her lol
I'm gonna go to bed now, But I feel accomplished for the first time in a while even if it's for something so simple as setting up anssh key for the first time3 -
Any Windows Sysadmins here? I have a question for you - How do you do it?
I only very rarely have to do something that would fall under "Windows System Administration", but when I do... I usually find something either completely baffling, or something that makes me want to tear our my hair.
This time, I had a simple issue - Sis brought me her tablet laptop (You know, the kind of tablets that come with a bluetooth keyboard and so can "technically" be called a laptop) and an SD card stating that it doesn't work.
Plugging it in, it did work, only issue was that the card contained file from a different machine, and so all the ACLs were wrong.
I... Dealt with Windows ACLs before, so I went right to the usual combination of takeown and icacls to give the new system's user rights to work with the files already present. Takeown worked fine... But icacls? It got stuck on the first error it encountered and didn't go any further - very annoying.
The issue was a found.000 folder (Something like lost+found folder from linux?) that was hidden by default, so I didn't spot it in the explorer.
Trying to take ownership of that folder... Worked for for files in there, safe for one - found.000\dir0000.chk$Txf; no idea what it is, and frankly neither do I care really.
Now... Me, coming from the Linux ecosystem, bang my head hard against the table whenever I get "Permission denied" as an administrator on the machine.
Most of the times... While doing something not very typical like... Rooting around (Hah... rooting... Get it?! I... Carry on) the Windows folder or system folders elsewhere. I can so-so understand why even administrators don't have access to those files.
But here, it was what I would consider a "common" situation, yet I was still told that my permissions were not high enough.
Seeing that it was my sister's PC, I didn't want to install anything that would let me gain system level permissions... So I got to writing a little forloop to skip the one hidden folder alltogether... That solved the problem.
My question is - Wtf? Why? How do you guys do this sort of stuff daily? I am so used to working as root and seeing no permission denied that situations like these make me loose my cool too fast too often...
Also - What would be the "optimal" way to go about this issue, aside for the forloop method?
The exact two commands I used and expected to work were:
takeown /F * /U user /S machine-name /R
icacls * /grant machine-name\user:F /T7 -

Deploying into linux containers (lxc) as of 2013 before docker even was da hype.
(Experience was a bit problematic tho, as it was in a highly virtualized environment whose backup would really badly kill the whole container every now and then: you could still ssh to the machine but with every access to the file system you'd lose your shell. and only the "echo 1 > /proc/sys/kernel/sysrq" would help to restart the box.) -

So last night I ran out of space on my root partition, apparently 30GB isn't enough for `/` besides `/home` and `/data` because both `/var` and `/usr` used around 14GB each so I decided to create partitions for them, had 500GB unallocated disk space on my SSD for if I wanted to install windows on my machine besides Arch Linux.
I edited the fstab file and sure enough, the partitions were mounted on boot, everything went fine. Then U realised the data wasn't actually removed from the first partition so I decided to mount the drive again and remove the files, the system still worked fine.
Untill I rebooted. Apparently the bit scripts require files in the`/usr` folder which wasn't mounted at boot, but right after. F*ck, system won't boot and now I'm in a recovery shell in busybox. After googling and reading the arch wiki I noticed a small message saying what you should do if you want to have `/usr` on another partition. I didn't do any of that.
After a couple of hours and a lot of reboots and chroots from a live USB to the broken installation it was fixed without losing any data! I did learn to read the manual or wiki to see any specifics when using more partitions. 😂2 -
Every time I try to use Android Studio in any linux distribution it makes file system read only mode and I have to use fsck command every time. Is there anybody who have the same problem as me 😐😐3

Out of the Operating Systems, I think Windows has the best file moving system.
Yes, you're unable to transfer files if they're currently in use, but you can start new file moving jobs in the middle of a current file moving process, and as of Windows 7, files that are unable to be moved for whatever reason don't cancel out the entire move.
Linux is next best because files will move regardless of if they're in use or not, and a file that is unable to be moved for whatever reason also won't cancel the entire move. However, if a new file move process is started, it will pause until the current move job is completed, which is a pain if moving a lot of large files.
Mac is the worst. One failed move results in cancelling the entire process. If a file will be duplicated or is unable to be moved, if you cancel that specific move, you have to start it all over again. No way to cancel or skip, just start it all over.4 -
Follow-up rant to my company. Today's day is fairly good, so let's talk about infra.
We're building upon an existing open-source project which is not intended to be extended (e.g. plugins).
Our backend-team somehow hacked symfony into the app, which made the actual work a little bit less annoying. But on the other side, there is absolutely no automation. Everything is setup by hand and I need to upload my sources to my dev-server and watch what files exactly are overwritten. Because if not, I accidentally overwrite core sources which will break the whole app, no matter what. If I forget what file I wrongly overwrote, I have no choice but to setup the core from scratch and apply our sources on-top, AGAIN.
The first time setup took me almost five days.
Oh yeah and the team shares one dev server, so whenever I feel like fucking with a mate, I can easily fuck up his system, since everyone has root-rights.
We're required to use windows, but our dev is linux and I am the only knowledgable linux guy. They need cheatsheets (to be fair, I need my powershell-cheatsheet).
We market the same app with some additional functionality, but we also have clients which require their own stuff. This case has never been thought-out, since for these specific clients, we also modify some core-parts. Which makes it a real hassle to add a basic new feature to that special customer.
At least our frontend is somewhat decent. Simple and without critical thinking, but it works and is decently understandable. I'll rant about that for another day, it's still tedious.
I know I won't stay there for long since I start my own stuff, but it's sad. Nothing is perfect and they _do_ want to make it better, but it's the usual "there is no time, client first" talk. On the other hand, they tell that we should be more efficient, but there is no way to be without looking back at the fundamental structure and what takes us so long.
I don't think I am able to change anything here and as I heard from co-workers, they already look for something new.

Experience with Plasma Mobile:
After an hour of confusion and bash file trolling (as in scrolling through a bash file, not trolling someone with a script), I ended up needing to reinstall Lineage OS on my phone.
While it's a new and seemingly exciting expanse for modern Linux and Android phones, it's very obviously not ready yet.
Even after fixing some bugs within the bash file, my phone seemed to have a mind of its own; prematurely attempting to boot into the OS during a critical part of the setup. Even after finishing the setup correctly, my phone never actually boots into the system.
While I like the concept behind Plasma Mobile, it does still have a ways to go. But I have some hopes that the project will start getting bigger and better as the time goes on.1 -

I remember the day I used Linux to enforce size quotas on user directories oh what a day
I was surrounded by horrible monsters wearing manho suits that made them appear superficially human... though the sounds screeching forth from their many toothed mouths in whining jarring tones would suggest otherwise and I used this wonderful feature : you can call most of the file systems commands on files !
did a dd to create a disk image specified to the correct size made an fs inside and mounted it straight into the home directory adding entries to the fstab to auto mount and setting the io permissions
It was so wonderful and the little bastards refused to use the server !5 -

So today my teacher told me to do that project for some competition or something(frankly, I don't remember clearly what this is for). He gave us the machines we need, the CDs with the systems we have to work with. We are supposed to make a properly working Beowulf cluster from the things I've been given.
Well, no.
Fucking no.
I am really okay with making this the way my teacher wants us to do. I am okay with installing an ubuntu 16.04 server that is completly irrevelant to the project, because it's not part of the cluster. I am really okay with using some weird linux distribution on the master nobody has ever heard of. But I'm not okay when the software we've been given(including operating system) has seven pages of documentation, escpecially when fucking screenshoots of how PXE booting should look like are roughly 70% of it. No, I couldn't find a thing on the internet about it. I couldn't read the fucking manual. There was no fucking manual. There was no fucking --help. There was no motherfucking english language. Everything was motherfucking spanish, including that 7 pages long document that was supposed to guide us through our work. It was planned to be done until march. The only reason I can think of about why doing the stuff the document tells us to do would take four motherfucking months is that we'd have to learn spanish to do this. And I'm not going to do that. Not because I don't like spanish or learning. Simply because I didn't sign up for this to learn languages.
And no. I can't switch to other, human purposed software. I am only allowed to use the things the teacher has given us. Because somebody has worked on it already couple of years ago and they had left a pdf file about how to install that ubuntu server I've been writing about a while ago. Which, by the way, was the "installation guide for animals". Showing how to install a system, screenshoot after screenshot.
It took about an hour to figure out the thing supposed to handle pxe booting computers all the time was telling us that it can't work because we had to configure ethernet interface manually. Because why the fuck not.

I have decided to set up a full Linux desktop pc, and go for everyday use and learn, mostly to catch up and understand better the whole UNIX and to get familiar with the command line there.
The problem is that there are hundreds of them, so if you can write some tips which one shall I go for?
Here is the info about what I need:
1 - I'm a web developer, so later I will move the work there too, capable of running a web server.
2 - I'm NOT looking for windows likeness or easiness, I'm looking for a distro which will help me the most to understand how it works in general, the file system, and the command line.5 -
First issue with Manjaro. I am not sure when it begun, but now, every single time linux uses the SWAP file, the entire system stays unresponsive, freezing (not even the mouse moves), so I need to wait until it finishes using the SWAP to be able to use it again.
I have 16GB RAM and I was not noticing that, but for some reason, Chromium started to use a little bit of the SWAP when the Hardware Acceleration were turned on and the mouses started to stop moving for a few ms/seconds.
So I tried it out: opened a VM with 8GB RAM and done, my PC were frozen for about 10 minutes, until I were able to use it again.
When I turn on the swap file, everything works fine again, even the VM. It does not matters with the SWAP is on a SSD or not.12 -
TL;DR As time goes by, I'm feel deeply in love with linux. An infatuation? :D
Before, I really dont mind how the file system works, permission setup, library installation, etc. as long I finished my project (before like 90% of the time I copy paste cmds). But now, after many hair pulling while debugging times, crying while rolling on the floor moments, and painful production deployments (wtf! it's working on my machine/dev server rants), it helps me clearly realized how amazing it is. I might be relatively new with the OS compare to others so maybe what I feel like now is like having a crush on someone in a bus :). But still, I just wanted to say thank you to all who are giving their time in developing/improving linux distros - you are heroes!
I'm hoping that I can contribute something soon :)

Goes to my comment on on of the rants to "Why linux cannot AVER be used by a normal user"
I'm pretty good with techs, OS, dev etc.
But here you go, a random error message which tells me nothing (Absolutelly nothing) and no way to fix it. No way to fix it, not even a hint where to look for solution, outside google. Sure, It took me around 5 minutes to find the problem googeling and copy/pasting some bash commands, but next time it happens and I don't have internet ? Well fucked.
This shit never happens on Wiondows or MacOs :) And that's why these 2 will always be user firendly ans linux will never be.
That's why linux will never be used by normal humains.
You 100% linux addict will point out directlly 'TYeah yours repos sources are fuckied" or whatever, but it IS NOT to user to know how sources, packages etc work. I want just update my system, if one source is not found, ignotre it by default ! How hrd is that ?

Hello everyone
Do any of you python programmers have any tips for simple projects you can do to learn python?
I am mainly a backend/system engineer comig from C++, slowly picking up rust and have been using bash as my scripting language so far. bash is nice because it is so fundamental in the linux world but you just dont get very far with it and its usually not pleasant to write.
So I would like to learn python, though I have no idea what I can do to practice it, so that I can just quickly whip up a script the next time I need something done in the file system or want to write a simple parser for something.
Do you guys have an idea of something small (not necessarily useful) which makes use of pythons strengths? Just looking for ideas here, so stick it all out 👋💕12 -
I've got a Linux Server running with 2 NVMe disks in RAID 1 configuration using mdadm. But if I want to create a big file, say 4GB, the whole system starts to hang.
I found out it's because of the journaling process which gives the CPU a long IOWAIT.
My problem is, I want to unzip a huge file, but this results in an immense server hang. Is there any way to do this without the server hang?
I unzip it inside of a docker container, if that is of any help.7 -

I am a programmer and I totally prefer windows.
1. I'm (besides other things) a game programmer, so I use the platform I develop for.
2. Linux is the best OS for developing... Linux. But I'm not developing linux. I want to use my OS and have it get in the way as little as possible, not test and debug and fix and develop the OS while i'm using it, while trying to do my actual work.
The less the OS gets in my way, the less stuff it requires me to do for any reason, the less manual management it needs me to do, the better.
OS is there to be a crossroads towards the actual utility. I want to not even notice having any OS at all. That would be the best OS, the one that I keep forgetting that I'm actually using. File access, run programs, ...DONE.
p.s.
if i can't trust you, a programmer, to be able to distinguish and click the correct, non-ad "download" button, or find a source that's not shady in this way, I don't want you to be my programmer. Everything you're expected to do is magnitude more complicated than finding a good site and/or finding the correct "Download" button and/or being able to verify that yes, what you downloaded is what you were after.
Sorry, but if "i can't find the right download button" is anywhere in your list of reasons why "linux is better", that's... Ridiculous.
6:15 "no rebooting" get outta here with this 2000 crap. because that's about the last year I actually had to reboot after installing for the thing to run.
Nowadays not even drivers. I'm watching a youtube video in 3d accelerated browser window while installing newest 3d drivers, I get a half-second flicker at the end and I'm done, no reboot.
the only thing I know still requires reboot within the last 15 years is Daemon Tools when you create a virtual drive, but that one still makes sense, since it's spiking the bios to think it has a hardware which is in fact just a software simulation....
10:00 "oops... something went wrong"
oh c'mon dude! you know that a) programs do their own error messages, don't put that on the OS
b) the "oops... something went wrong" when it's a system error, is just the message title, instead of "Error". there's always an "error id" or something which when you google it, you know precisely what is going on and you can easily find out how to fix it...18 -
I hate that I need to have Adobe Creative Cloud and its accompanying bullshit on my computer to use Adobe XD for mockups... how it intrudes on my file explorer as a shared drive... how their idea of "free" is planting a seed on my system to leech off of me in the future... how it just crashed my explorer while updating... this is why I run Linux on my laptop, why I wouldn't use Windows at all if it weren't for gaming, and why I ALWAYS use open source alternatives when they are comparable in functionality and performance. In the same sense that people don't like big government, I don't like BIG SOFTWARE.2

I try to delete a partition from my sundisk Pendrive using GParted but when I do this I got the error that is shown in the image.
And If I try to use "fdisk" which run `sudo fdisk /dev/sda` following command it gives me ```welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
fdisk: cannot open /dev/sda: Read-only file system```
following error does that mean my pendrive permanently broke can anybody help me!

I want to learn about Linux file system. My searching led me here => https://refspecs.linuxfoundation.org/...
Is this a good place to start with file system?
P.S. I barely know Linux apart from basic commands.3
