Asides[edit | edit source]

Greg Rust OS programming https://www.redox-os.org/

Anecdote from job interview programming questions, strace, debugging.

Loren Lineage of Mac cmd line tools.

Doug What is rust? A compiled language? Loren/Greg: Yes, compiled, safer memory management and access, strict and expressive typing. Manual garbage mgt., tracks lifetimes of objects to manage unsafe behavior. "Static garbage collection" at combile time; objects dropped when they go out of scope.

Questions, Discussion, or Coworking[edit | edit source]

Questions[edit | edit source]

Justin (Justin will dig through Wiki to answer these, or ask again, or ask around)

  • Does a Network & Infrastructure (graphic) map exist?
  • SNMP?
  • Ping/Uptime/Status monitoring?
  • Backup systems?
  • Outbound IP traffic obfuscation? Need for it? Plausabile Deniability?

Loren: Monkeybrains, Wireless ISP and IP provider for the NB space.

"Enduring Hosted Services"

Justin: Do we have status.noisebridge.net ?

Loren: We're personally monitoring various services, e.g.: metrics endpoint someone may be running.

NB Systems are "robust because we don't make long dependency chains."

Justin: If Loren and Mark dropped out, would anyone else be able to effectively manage infrastructure? What documentation exists for even who the current maintainers and are? How do we map and guage various volunteers current, ongoing, or waning interest in infrastructure projects (infrastructure broadly defined as things most visitors at NB rely on daily) ?

[Conversation interrupted - Trash day!]

For next time[edit | edit source]

Possible TODO[edit | edit source]

Ideas / Proposals[edit | edit source]

Justin[edit | edit source]

EtherPad self-host enabing plugins like Wikitext parser

Embed Etherpads in MediaWiki: https://www.mediawiki.org/wiki/Extension:EtherpadLite

Import and Export WikiText from Etherpad (plugin) https://www.npmjs.com/package/ep_mediawiki

Local mesh-network or near field coms, to connect those present in the physical space? Discuseed at 11-25-24 meeting, Who's In The Office

Consider also: Bridgefy messaging App and SDK (Signal protocol included)

Standing Issues[edit | edit source]

Discord blocked from our IP range. J: Can outbound network traffic obfuscation solve this? L: Probably not an issue of scale that folks would devote time/resources to solving it. See no other practical reason or application for IP layer security at NB [paraphrasing]
