I need to quench my thirst for knowledge and learn something new just for the sake of it.
I’ve already learned:
-
Equations and pivot tables in Excel
-
Vector graphics in Inkscape
-
Music mixing in rekordbox
-
Personal VPN on a raspberry pi 4 with OpenVPN
-
LAMP stack web hosting
-
Streaming & video capture with OBS
-
Manual & automatic backups with FreeFileSync
Things I’m open to:
-
FOSS (even beta) or free-as-in-beer software
-
A high or low learning curve
-
Tools for niche fields that I’d otherwise have no reason to learn


Get your finances in order with Firefly III and Waterfly III (Android app, available in F-Droid)
I like numbers and was really tempted to go all in into this rabbit hole but this ends up being a lot of work and stress if you try to maintain it manually. It’d be ideal to be able to automate imports from your banking apps but those don’t really exist, or depend on some possibly sketchy 3rd party services that I dont trust with my finances
I use a paid service (which might itself depend on one of those 3rd party bank syncing companies, idk), but it’s wild to me that banks haven’t figured this out yet and cut out the middleman. They can’t want their customers to be exposed to more risk than necessary
