Latest TIL

Here are interesting things I found while browsing the web. It's ideas and thoughts, new findings, and reminders regarding software development. I see it as a second brain for all things related to development and a way for me to practice Learning in public.

This is heavily inspired by Lee Byron's TIL and builds on top of my initial attempt with my Devlog.
