I was planning to focus on open source work after finishing my company work today, but I ended up spending time on an unexpected CVE instead.
If in a few years no humans are writing code anymore, then this might be the last moment we truly get to enjoy it. So enjoy it fully and appreciate the present, so you won’t look back with regret in the future.

Going to report a bug literally any Python project on GitHub to find @hugovk.dev already got there before you, reported it and fixed it. Every time.
Most of my recent OSS contributions are connected to projects at my company, even if the contributions are small or simple. So I still believe the best way to start contributing to open source is by working on, or aligning with, your day-to-day projects :)
Sometimes it is good to try to keep a distance from the topic that I am biased on
