Unfortunately, Linux manuals are pretty scattered around. I’ll try to find something for you:

• If you want to learn the very basics of Linux command line, here’s what I found on the web: http://www.ee.surrey.ac.uk/Teaching/Unix/ ;
• For on how to use GNU user-land tools (Bash, cat, less, grep, sed, etc.), I recommend the GNU manuals which are very well-written: https://www.gnu.org/manual/blurbs.html (example: Bash manual);
  • GNU manuals are also downloaded for offline read by default. These manuals are provided with info.
• For GUI desktop, it depends on what Desktop Environment (DE) you use:
  • KDE wiki with tutorials: https://userbase.kde.org/Tutorials
  • GNOME app overview with documentation: https://apps.gnome.org/
  • If you don’t know what DE you use, KDE uses sharp edges for windows and GNOME uses round edges ( 👁️👄👁️ ).
• For system, as @[email protected] pointed out, for system-specific stuff, there’s ArchWiki that has topics about everything.
• If you want to understand what are the /usr, /usr/local, /etc, /dev, etc. filesystem directories, you want to look at the Filesystem Hierarchy Standard: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html
• There is also a free training course for Linux: https://training.linuxfoundation.org/training/introduction-to-linux/
• If you’re a developer and want to find out how deep the rabbit hole is, you may want to look at an online book Operating Systems: Three Easy Pieces: https://pages.cs.wisc.edu/~remzi/OSTEP/

EDIT: Forgot this important material:

• If you need to know command-line argument specifics for a particular program, use manpages (For example, to find brief information about grep, type man grep in your shell, and info grep if you need a complete manual).

You can try to enroll into Linux Foundation Certified Sysadmin course. It is quite a respectable certification. Try to have some practice every day as well.

That profile pic looks cool, though

I’d recommend rather boring Debian. Archlinux as well if you want to dive deeper.

EDIT: For Debian, you want Debian Testing.

I got used to XFCE, but, with my new awesome Tuxedo laptop, I got KDE as a DE for a stock OS, and I could say it feels much more complete. But the performance drops, when opening a terminal, for example.

I could only tolerate ElectroBoom-style “This video is sponsored by oscilloscope company” ads.

Haha, I want to see a race condition going on with real matter.

It’s more efficient for memory until you start working with different data. Threads also rely on the same syscall on Linux, clone(2), but they don’t share the entire context by default, so they’re more lightweight. It is recommended to use pthreads(3) API instead of fork(2).

If you fork a process, then it’s the two separate processes but sharing the same memory with copy-on-write mapping.

It depends on non-free Google Play Services for push notifications, which puts you into a requirement to use an unmodified Google Android, which is potentially dangerous for a privacy app like this.

Anyways, when it comes to E2EE IMs, Matrix ecosystem is much better.

Yes, there are.

As the others made a good point, Linux is the kernel (program that connects hardware altogether and manages processes). GNU is an organisation beginning in 1983 that made some vital userland programs (Bash, GCC, readline, GNOME, GTK, GIMP, etc.) as a replacement of the proprietary ones found in UNIX and Windows. Linux is created by a Finnish student Linus Torvalds and is not a part of the GNU project but it’s been licensed under the GNU General Public License (GPL), the first free software license.

Linux is used by a lot of companies, and some of the products that have Linux inside refuse to accept the paradigm of software freedom. Examples of this are: Chrome OS, Windows Subsystem for Linux, Google Android and some (but not all) appliances (like routers) that are locked-in and contain proprietary blobs.

Therefore, in technical discussions, I use the word “Linux” to refer to the OS, as “this software is compatible with Linux”. But, when I want to stress out software freedom, given a large influence of the GNU project, I say “GNU/Linux”.

Add a user agent checker to your website and add tag: ‘Your browser, Google Chrome, is not supported. Please open this website on Firefox.’

I used to use Arch Linux. It’s really good, honestly, especially if you want to know how the OS components work from inside or make something custom. For anything else, I would recommend Debian and its non-snap-based derivatives (Linux Mint Debian Edition or Tuxedo OS, or KDE Neon).

IDK, I used to have a dedicated software for playing with CUDA. Most of the image-specific AI stuff from the internet require 8 GB of VRAM or more, though.

Nowadays, I don’t feel the need for GPU-accelerated computing, though. If I needed, I would write Vulkan compute shaders for that thing.

There are programs (LyX, TexMacs) that implement WYSIWYG for LaTeX, TexMacs is exceptionally good. I don’t know about the standards, though.

Another problem with LaTeX and most of the other document formats is that they are so bloated and depend on many other tasks that it is hardly possible to embed the tool into a larger document. That’s a bit of criticism for UNIX design philosophy, as well. And LaTeX code is especially hard to make portable.

There used to be a similar situation with PDFs, it was really hard to display a PDF embedded in application. Finally, Firefox pdf.js came in and solved that issue.

The only embedded and easy-to-implement standard that describes a ‘document’ is HTML, for now (with Javascript for scripting). Only that it’s not aware of page layout. If only there’s an extension standard that could make a HTML page into a document…
