  • Understand the difference between a joke and an insult.
  • Do not harrass or attack members of the community for any reason.
  • 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.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
    • 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. Even if you watch it on a Linux machine.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.

    Zip makes different tradeoffs. Its compression is basically the same as gz, but you wouldn't know it from the file sizes.

    Tar archives everything together, then compresses. The advantage is that there are more patterns available across all the files, so it can be compressed a lot more.

    Zip compresses individual files, then archives. The individual files aren't going to be compressed as much because they aren't handling patterns between files. The advantages are that an error early in the file won't propagate to all the other files after it, and you can read a file in the middle without decompressing everything before it.

    Yeah that's a rather important point that's conveniently left out too often. I routinely extract individual files out of large archives. Pretty easy and quick with zip, painfully slow and inefficient with (most) tarballs.

    Can you evaluate the directory tree of a tar without decompressing? Not sure if gzip/bzip2 preserve that.

    Nowhere in here do you cover bzip, the subject of this meme. And tar does not compress.

    [–] [email protected] 7 points 5 months ago (1 children)

    It's just a different layer of compression. Better than gzip generally, but the tradeoffs are exactly the same.

    Well, yes. But your original comment has inaccuracies due to those 2 points.
