Zombie Docker Container
A Docker container can end up stuck in Up state while actually being dead inside — docker stop and docker kill both fail with 'did not receive an exit event', and the app inside is unresponsive. Here's the root cause and a script that recovers it…
Kitty Terminfo
If you've started using Kitty as your terminal emulator, you may eventually hit a particularly annoying problem when working over SSH: everything works fine as your normal user, but as soon as you sudo into another account, terminal applications start behaving strangely…
