2. Be civil
- Understand the difference between a joke and an insult.
- Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
- Don't get baited into back-and-forth insults. We are not animals.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
- Bigotry will not be tolerated.
3. Post Linux-related content
- Including Unix and BSD.
- Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of
sudoin Windows. - No porn, no politics, no trolling or ragebaiting.
4. No recent reposts
- Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.
5. π¬π§ Language/ΡΠ·ΡΠΊ/Sprache
- This is primarily an English-speaking community. π¬π§π¦πΊπΊπΈ
- Comments written in other languages are allowed.

6. (NEW!) Regarding public figures
We all have our opinions, and certain public figures can be divisive. Keep in mind that this is a community for memes and light-hearted fun, not for airing grievances or leveling accusations. - Keep discussions polite and free of disparagement.
- We are never in possession of all of the facts. Defamatory comments will not be tolerated.
- Discussions that get too heated will be locked and offending comments removed. Β
Please report posts and comments that break these rules!
Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't remove France.

But if it's just an old api, why is it still in the spotlight? I understand compatibility is important, but I'm almost never hearing half as much about any of the other old apis--can't even really think of one either
It covers the majority of basic things you need your computer to do and it works practically everywhere. If you target POSIX (and you avoid uncommon features that some systems don't implement), your program will probably run on Linux, macOS, *BSDs, random OSes you've never heard of, Windows (with certain setups), maybe your toaster, etc. It has a lot of inertia behind it at this point.
How do you improve upon perfection?
Ohhh, so it's old but also best by test, this makes it pretty cool then
Because it avoids this
Itβs the baseline of UNIX, with Linux maintaining most compatibility, meaning servers around the world, desktop environments including MacOS and GNU/Linux, gaming machines (including video game consoles like PlayStation and Steam Deck), mobile devices like Android and Apple Devices, mainframe computing systems, embedded systems, so on and so forth. It makes up the backbone of our technology infrastructure. It continues to be iterated on, and is tightly bound with the C programming language and its improvements and iterations.
