Git 3.0's upcoming SHA-256 default will be a costly mistake

    So they’ve been talking about this for many years, planning, and finally announce when they’re going to switch the default.

    So this is the right time to post that everything they’re doing is wrong? Did you engage in all the discussions about it and how best to handle it? Whether SHA-256 was the best solution?

    I don’t see anywhere that it talks about alternate proposals or why they might have been better. Why the particular suggestions here were rejected.

    This seems like a bunch of Monday morning quarterbacking.

      The plans have been on display in a cellar. Beware of the leopard.

        I don’t understand what this is supposed to mean.

          nofunsir is a stoichastic parrot, matching to a bit in Hitchhikers Guide to the Galaxy, wherin the protagonist should have known to protest a plan to demolish his home where plans where clearly documented in a hard to find place that they could not have known about. It is not a good pattern match, because git has been discussing this in public on documented mailing lists for years.

            No I'm not. Real thumbs here. If anything this paragraph sounds like LLM slop

              Run it through pangram if you want, I wrote it with my human brain. What I did not do, however, was parrot an inapplicable quote.

              In what way has git's discussion of their move been hidden away in a metaphorical basement?

                I'm sure the cellar was also documented, Arthur eventually found it, did he not?

                Mailing lists are basements in 2026

                  Since 1999, we've had Google to help people find things. True, a mailing list isn't an Instagram reel delivered directly to your face with audio and blasted out on Fox News, but if one was interested in the development of git, an LLM or a Google search would readily tell you about the existence of those mailing lists.
