Discussion & lesson derived from questions, comments on recent solutions or ongoing problems. Fixed the NB network issue after the meeting.

Introductions

Welcome to infrastructure (computing, not civil/roads/power). We also discussion self-hosting, FOSS software, & the deep roots of standards enabling the internet. RFCs.

• Zander - interested in the definition of instrcture, just build my first road, (..)
• Joe - just moved here from the UK, getting into
• MisterName - like coming here for the discussions, working on a project hoping to present in a few weeks, hopefully under nix
• Ryan - first time actually coming, meaning to for a bit. I do robotics during the day, self-host some, some use of cloud stuff. Experiencing information overload, trying to bring some order, instead of hacking it together
• Elan - do a lot of self-hosting at home, vested interest in NB having good infra as well
