It was a nonstop game of my IDE’s refactoring features, a bunch of `xargs perl -pi -e 's/foo/bar/;', and repeatedly running `cargo check` and `cargo clippy --fix` until it all compiled. It was a 4000+ line change in the end (net 700 lines removed), and it took me all of that 8.5 hours to finish.
Could an AI have done it faster? Who knows. I’ve tried using Cursor with Claude on stuff like this and it tends to take a very long time, makes mistakes, and ends up digging itself further into holes until I clean up after it. With the size of the code base and the long compile times I’m not sure it would have been able to do it.
So yeah, a typical day is basically 70% coding, 20% meetings, and 10% slack communication. I use AI only to bounce ideas off of, as it seems to do a pisspoor job of maintenance work on a codebase. (I rarely get to write the sort of greenfield code that AI is normally better at.)
