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


One thing I want to learn which seems important to me career wise is HEC-RAS, a hydrological River Analysis Software. I think it’s free?
From this you can build your own predictions of when flooding (or drought!) will occur in your local area
As a professional water engineer it seems unfathomable to me that someone would learn HEC for fun, but it’s really cool that you want to! Yes, it is free and maintained by the US Army.
Just make your inputs are right. Garbage in, garbage out.
