Community rules (click to expand)

1. Follow the site-wide rules

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 sudo in Windows.
  • No porn, no politics, no trolling or ragebaiting.
  • Don't come looking for advice, this is not the right community.
    • 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. πŸ‡¬πŸ‡§ Language/язык/Sprache
  • This is primarily an English-speaking community. πŸ‡¬πŸ‡§πŸ‡¦πŸ‡ΊπŸ‡ΊπŸ‡Έ
  • Comments written in other languages are allowed.
  • The substance of a post should be comprehensible for people who only speak English.
  • Titles and post bodies written in other languages will be allowed, but only as long as the above rule is observed.
    • 6. (NEW!) Regarding public figuresWe 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.

    Yeah if the url is https://i_hack.you/ yeah that will be easy to spot. But imagine an attacker just to a "patch update", updating the url and hash to the malicious repository, and use a typo squatted domain/repository, that will make it harder to spot.

    No, it would actually be quite easy to spot.

    Nixpkgs templates the source code url fro the url, and then it injects a variable

    Here is an example from bash:

    pname = "bash${lib.optionalString interactive "-interactive"}";
    version = "5.3${fa.patch_suffix}";
    patch_suffix = "p${toString (builtins.length upstreamPatches)}";

    src = fetchurl {
      url = "mirror://gnu/bash/bash-$%7Blib.removeSuffix fa.patch_suffix fa.version}.tar.gz";
      hash = "sha256-DVzYaWX4aaJs9k9Lcb57lvkKO6iz104n6OnZ1VUPMbo=";
    };

    If the url were to be changed, it would show up as a change in git when someone is reviewing before merging.
