If you want to check the progress of a recursive grep, going trough lots of files, just sudo ls -lah /proc/[GREP PID]/fd. You'll see which files grep is accessing at the moment, which will give you an idea how far it is in the search.
After changing from bash to zsh I found it quite annoying that ⌥ + ← was always jumping to the closest white character, instead to space or slash (or some other special characters considered to be word-separators).
Fortunately it's possible to change this behaviour by editing the WORDCHARS env variable.

Today I learned that our GitLab runner deploys itself. Which means that if you push a change which breaks it, later when you'll try to fix it, it won't be there to deploy the fix.
Today I learned that even though cloud tasks are a separate product now they still need your App Engine project to be enabled. Otherwise, all tasks will just hang and any attempt of forcing them to execute will result in a 500 error.
