Meetups/Infra/2025-12-01

Advent of code + advent of sad servers, systemd linting pursuits, uv neat tricks (uvx + uv tool) (and uv run --script #! "sha-bang"s in files), git worktrees, and 1996 AR hardware shown off. 🐈

Introductions

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

• Loren - cloud engineer, infra, "our site feels a little slow right now"
• Alex - ML, iot weather station mgmt
• Maxsym - serverless workflow,
• Alex also - robotics, openwrt meshnet, agents and k8s writing software
• Jeanie - devops/sysadmin, reading about noisebridge in the news
• Derek - getting back into rust, looking into systemd linters, uv https://github.com/bmad-code-org/BMAD-METHOD
• Daniel - mesh network drones
• Danny - pen testing, 2nd time at noisebridge, smart smoke alarms
• Doug - likes computers, retail data
• Kevin (mister_name) - here to learn, ML, python, node, linux, "blah blah blah"
• Dan - digital signal processing, giving c++ another try by doing AoC
• Jet - has a cat🐈, drones, automation, cybersecurity, AI (learned about it this morning)
• Wheezy - data nerd, GPU, computers, software, building data sets, scraping
• Josh - i came here for a quiet room with nobody around. also into vintage computers
• Erik - brought a fun piece of 1996 hardware, want to show and tell. Glasstron Sony PLM-50 original Japanese version. see https://github.com/dontriskit/anti-anti-scraping for scraping tips
• Frank - software, thinking about 2038
• Robert - interest in consumer computing technology (laptops, phones, PCs)

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!

• Advent of code (25 d) + advent of sad servers (12 d)
  • http://adventofcode.com/ -- jet says, please just do it by hand. See site's QA.
  • https://sadservers.com/advent

• systemd -- derek looked for linters
  • cuelang.org -- dhall
  • augeas.net

• uv -- neat trick
  • you can install things globally! uv tool install, uvx for temporary use
  • uv -- building toward profitability

git work trees: https://git-scm.com/docs/git-worktree something that can help agents work on multiple features in different branches. Hard for humans to use but maybe it's getting some improvements in recent versions of git.

• someone shared at a meetup. using git-worktrees plus docker containers, then giving claude code access to tmux, logging in to each of the containers -- there they have more freedom to do whatever, and you don't need to e.g. use environment variables to set and look up separate ports for separate dev servers for each of the worktree instances

• the ai checkins.

• vpn for circumventing price discrimination -- on ai tools, dev tools, flights.

• close with Glasstron

Outros

• Erik - scraping techniques
  • Jet - as a webmaster, I post a sitemap. (It's like shooting yourself in the face with a shotgun)

• Alex - do lots of test driven develop.
• Property-based testing https://github.com/HypothesisWorks/hypothesis https://hypothesis.works
• Maxsym - learning next week, how to get back from Europe. How to certify workers in use of online tools, with HAR and broad use, exploring.
• Alex - cuda + gpu optimization. PyTorch. esp tips & tricks.
• Jet - want to host shark tank time.
• Robert - fun vr devices from Eric
• Jeanie - uv
• Daniel - git worktrees, embedded use, how to leverage
• Danny - uv run --script #! sha-bang. Agent workflows.
• Doug -- uv! have to dig in more, pip install
• Kevin - agents, agents, agents --
• Dan - uv
