Ask HN: How do you manage knowledge you accumulate as a developer?

I mean the practical stuff: bug fixes you figured out, architecture decisions, things you learned the hard way, solutions you'll probably need again in 6 months.

I've talked to ~20 developers over the past week and the pattern I keep seeing is: everyone writes things down somewhere, almost nobody can find it when they need it. The problem isn't capturing — it's retrieval.

Notion, Obsidian, plain files, GitHub wikis, Confluence — all have the same issue: search is keyword-based and only works if you remember exactly what you wrote.

Curious if others have found something that actually solves this, or if you've just accepted that you'll Google the same problem twice.
