I'm experimenting with live-evaluating tests in my programming language project. It's relatively fiddly to hook up a UI for this, but it saves a precious keystroke to run the tests! I'm hoping that it results in more, better tests due to the convenience.

I'm still experimenting with patch display in difftastic. The change to the imports are clearer in the patch mode, but the side-by-side mode does make the if/else changes more readable. Patches are probably worthwhile anyway due to their machine readability.

Software is typically malleable. What software is the hardest to change? For me, the obvious cases are APIs near the bottom of the stack (e.g. imagine changing a Linux syscall) or systems with a large number of users (due to Hyrum's Law).
