@argv_minus_one@mastodon.sdf.org Somehow I get the feeling that you need to retry and maybe get more practice with it. Maybe use a better model than in your last try. Maybe give it more context. Claude >= Opus, maybe also a recent Gemini [Pro] (High). I have the paid plan (~20 EUR/m), not sure if the free plan is as good. Maybe use Python and C code (I had quite a lot of success with that). It also worked great for html/css/js (Claude Fable + Opus). That's just my experience, initially I was also skeptical.

@argv_minus_one@mastodon.sdf.org To get a bit more practical / specific: Did you notice the increased amount of bugs being fixed recently? Tons of CVEs and also lots of non-CVE fixes. Commercial SW as well as FOSS. Quite a lot of these were discovered by AI. A lot of these were in the code since many years and were NOT discovered by humans - neither in code review at commit time, nor in the years after that.

April 1st is now globally over - relax! AI won't decide about what's in your backups.

@argv_minus_one@mastodon.sdf.org "this bad at programming" seems to be something you experienced. My experience is quite different, so I disagree. It's hard to see whether something was reviewed, but that is not an AI specific problem. You can also not see how much a human developer was thinking while they developed some piece of code. A small bit of evidence (but no proof) sometimes can be seen if there is a big change (AI assisted) followed by some small changes (human corrections).

borg 1.4.4: if you package for big-endian architectures (most stuff is little-endian nowadays), you will need this patch: https://github.com/borgbackup/borg/issues/9521

1.4.4: broken on big endian architectures · Issue #9521 · borgbackup/borg

In the new header value validation code, due to missing _le32toh() calls for num_buckets and num_entries, it crashes with this on big endian architectures, like s390x, hppa, sparc64: E ValueError: ...

@frank Good idea, guess we need an option for that. Some users may want more, some less!

@argv_minus_one@mastodon.sdf.org It's not the same task, but considering these amounts, I think some people should re-think their point of view that "human written code is good and AI written code is bad". Obviously human written code isn't THAT good, otherwise AI would not find tons of bugs in it. And if the developers had used AI while writing the code, maybe the bugs would not be found in production, but before release. Years ago that was not possible, but nowadays it would be quite good for quality.
