I just released v1.0.0 of my actions-rust-release action. This is a big, breaking change. See the release notes for details, but the summary is that this splits the action into two pieces. The first…

A series on how software architecture shapes AI-driven code degradation. An objection to the last post turned out to be right, and fixing it produced a better result than the one it demolished. Every…

A series on how software architecture shapes AI-driven code degradation. This post reports the strongest result against the position these posts have been arguing. It replicated in both runs, so here…

Sometimes, you create a branch off another branch, do some work on it, and want to know what the original branch was pointing at. For instance, if you're looking to clean up your Git history, but…
