- 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.
- 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.

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.

- 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.

Download of 6GB is wild, is that re-downloading the entire package for each one that needs an update? Shouldn't it be more efficient to download only the changes and patch the existing files?
At this point it seems like my desktop Linux install needs as much space and bandwidth than windows does.
Patching means rebuilding. And packagers don't really publish diffs. So it's use all your bandwidth instead!
Which is WAY more economical.
Rebuilding packages takes a lot of compute. Downloading mostly requires just flashing some very small lights very quickly.
Yeah, totally is. There's a reason nobody publishes diffs
openSUSE Leap does have differential package updates. Pretty sure, I once saw it on one of the Red-Hat-likes, too.
But yeah, it makes most sense on slow-moving, versioned releases with corporate backing.
Ooh, got any links on how Leap does this? My searching isn't yielding much
Had to search for a bit, too, but finally found the relevant keyword: Delta RPMs
(Which also explains why it's a Red Hat / SUSE thing. π )
Here's a decent article, which links to some more in-depth explanations: https://www.certdepot.net/rhel7-get-started-delta-rpms/
Thanks, really well hidden feature here for someone I'm sure
I don't think anyone actually uses these
