LLMs are surprisingly good at reducing crash samples. I've had success with "this project crashes my static analysis tool with the following command, try to shrink the repro whilst preserving the crash. Commit each smaller version to a branch".

I'm experimenting with jj this weekend. It seems pretty nice so far, but the mental model is pretty different from git. For example, there's no `checkout` command. You do `jj new ABC` to switch to a commit, which creates a new empty commit on top of ABC.

It's a small thing, but I'm much happier with --version in the latest version of difftastic. It shows the release number and the commit date. This gives you a reproducible build with age info. It also shows OS, arch and compiler, because those are useful in bug reports.
