I realized I read quite a lot on the web. I spend a lot of time browsing answers on StackOverflow and reading documentation.

For the most part, such information is only useful once and it's OK to forget it. But occasionally, I'd come across a new bug that reminds me of an older problem I had seen before. At that time, I'd wish I could remember how I solved that problem earlier.

I take notes in Obsidian when I try to seriously learn something new. In the meantime, I'd create flashcards in Anki if I find what I'm learning really useful. ⋯
