(TODO summary)

Introductions

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

• Loren -- anubis. links. talk about infra, self-hosting, noisebridge infra
• Robert -- i like linux in the same way some people like football, parlays, head trauma,
• Wolf -- I self-host, playing this week with DuckDB
  • how do you deploy? dl, unzip, run it
• Jameson -- I run a small startup, host sites on cloudflare sites, hoped to work with Erikk tonight on Noisebridge LTE hosting, open-source network core, MAGMA core self-hosting. Terraform & K8s

- rob Q, does it have to be adapted to terraform and k8s? or could you deploy k8s on a server and do it "normally" - l: it's written for ubuntu 18? so,

• Greg -- programming, run some infra, anubis might be of interest for me
• Zaccy -- mostly sitting in, somewhat of a ... free software absolutist. Our compute is an extension of us. Interested in Noisebridge as a testbed of it, digital autonomy for it.
• Skanda -- interested in free software, have worked for big tech and startups. Using cloud does not seem sane, cost and control-wise, trying self-hosting. With AI tools -- can I replace SaaS tools. Would like to share some slides today.
• Chris, sitting in, designer, full-stacker -- hosted some services
• Sylvia -- self-described creature, , set up auth on CF Worker, hosted something on home server and put on internet in last month
• John -- quit corpo job recently, getting back in touch with OSS, linux. Scaffolding new learning with Obsidian, devops/sre experience
• Matty -- 18 taking a gap year, at NB for 2mo, here to observe
• Lukas -- Work on LLM visualization. Voxel rendering, mistral 7b. Pytorch, tensor ouotput. OpenGL bind and output.
• Grady -- in our day job, Lukas has developed a new post-training method.
