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.

    I forgot but do browsers download binaries as executable?

    One of the big issues with windows is the fact that it uses file extensions for determining file type, so EXEs can just be instantly run after downloading, which led to MSFT making the "Mark Of Th Web" attribute, which moved hackers into finding every type of bypass for MOTW.

    I think straight bin downloads require you to chmod +x first, but you could also probably bypass it with any archive format like .tar.gz or opting for a .deb or .rpm.

    The upside is that you really shouldn't be downloading raw bins outside of the package manager, but there are a bunch of tools that only ship as appimages, so you're kinda screwed if you download and execute from an untrusted source.

    The weak link on Linux is the number of tools that trained the users to curl ... | bash

    Sometimes! I've definitely had some executable files that have downloaded with the x bit flagged.
