FOSS or otherwise
Obsidian.
Since the Internet in general is getting harder to find genuine information, it is becoming increasingly important to save anything important to you. One day it could just disappear without warning. Obsidian can be used for an offline knowledge base. Design it however you like. I do recommend NOT watching YouTube Obsidian “gurus”, their system works for them not you.
Personally for me, it allows me to dump stuff out of my noggin good or bad. That way I can stop thinking about it and move on. A form of self reflection. I have a bad habit to hold onto thoughts and go down a rabbit hole with them in an unhealthy fashion. Basically journaling but I can store things I have learned long term.
The beauty of it is Obsidian (or really any other writing app) allows you to develop a system of writing for you. I’m not the typical writer but Obsidian allows me to write without worrying about the organization so much.
Yep, today I’d say obsidian and syncthing, they’re the bread and butter of my life right now. Although it feels sad and weird to see the small app I discovered 2 years ago starting to enter the «selling template» and «enhance your experience» that notion also took a few years ago «althought it’s a completly different company culture»

One of these is actually what got me started with it. I do not rigidly adhere to their system but it was a nice starting point I have since adapted to my own style. If I had gone into it blind I would have made a lot less progress because I’m kind of dumb when I have nothing to go off.
