(TODO summary)

Introductions

• [name] - [background]. [goals for meetup, or interests to explore]

• Loren - background in cloud and platform engineering things, quantum doomsday
• Elan - like declarative infra, resurrectionist
• Daniel - web dev, hobbiest of many things, enjoys simplifying infrastracture, dislikes perfoa
• Derek - Applying to jobs and applying to more jobs
• Doug - likes computers and economics and business logic
• Kevin - likes computers, AI, Data, data engineering, API and today, navigation systems, working with a
• Victor - like all things computers, works in playform stuff
• Sam - Lies wikis and hates computers
• Alex - big push to multi agent architecture, 100 agents, XMTP quantum resistant crypto
• Azmath - hardware engineer, making games, wikipedia games, excited to be here
• Gwen -
• Max - Code Wizard, infra is cool, again on an NLP grind.

Lesson or Demo

• Read aloud: clarify for meetup. We are taking notes in a riseup pad (or I am--help appreciated, and links). We have meeting notes posted to the wiki. noisebridge.net, search Infra, or Meetups/Infra. (the Infrastructure page has a disambiguation link.)
• Shell, web services, self-hosting, networking!

• Daniel - Mulvad VPN? Is it post quantum?
• Derek - Interested in the garden move to Talos
• Doug - wishes he was better at number theory
• Kevin - interesting, dooms days strictly online, air gap plan underway.
