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

I learned a decent bit about how biometric authentication works (or at least this specific implementation) by installing, setting up, and tweaking settings for Biopass. I also learned about how when you do first login using this method, it can fail to unlock keyrings because the password authentication has been bypassed so no password has been provided to unlock the keyring. It includes anti-spoofing local AI models, and the dev plans to have the option for the user to download and use any model for anti-spoofing/recognition. Interesting stuff.
