Calendar self-hosting software, personal dev stack "what's in your dev portfolio", IPFS, DIDs, and llm haters club.

Introductions

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

• Daniel -- I don't do infrasturcture. Web dev. Mod thinkpads
• MrName, aka Kevin -- mod thinkpads also, working on some ai stuff, with llms and older stuff. Building android app, with Kotlin, interesting and terrible
• Ben, bengo -- write typescript, linux stuff -- into web standards, social web working group, activity pub wg, working on stuff with credentials wg, DID decentralized identifiers. did chaining.
  • foaf? [Friend-of-a-Friend RDF](http://xmlns.com/foaf/spec/) Indemedia.org project, which led to odio, which became twitter.com.
• Alex -- owrk on machine learning stuff, no topic requests today
• Sarah -- used to do infrastructure, now embedded linux
• Loren -- scraping
• Sameer -- i like computers, done infra in the past. Now doing it re
• Cole --

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!

Decentralized Identifiers

Ben spoke at length about DID. Some of that was [captured here](https://pad.riseup.net/p/M6tjosrPIJrgHeNOV2E9-keep).

• Calendar app -- cross platfrom
  • trying NextCloud. yunohost.org -- see other apps

• Sharing dev stacks
  • cli:
    • llm (simonw tool)
    • uv (pip, in rust, with VC money).
    • fzf -- enables better Ctrl-R recall of previous cli incantations, easier file search (`fzf` indexes from current directory and enables quick file/pathname search)
  • aider (claude code?)
  • storybook: keep it sandboxes away from the rest of the project. Great simple success.
    • https://storybook.js.org/
  • node js -- now ships TypeScript support. Not complete support. Strips type annotations at runtime w/o precompile. (zod).
    • node js now has built-in test runner

• • http://www.incompleteideas.net/IncIdeas/BitterLesson.html

• • Sameer's righteous war against macOS Spotlight -- fzf

function resc
    set file (cat ~/.cache/files/cache | sort | uniq | cat - ~/.cache/files/documents_downloads_resources | fzf -i --layout=reverse)
    if test "$argv[1]" != ""
        set flag '-R'
    end
    if test "$file" != ""
        echo "$file" >> ~/.cache/files/cache
        open $flag $file
    end
end

function index_resc
    fd --absolute-path \
        --type directory \
        --type file \
        --search-path ~/Documents/ \
        --search-path ~/Downloads/ \
        --search-path ~/Applications/ \
        --search-path ~/Resources/ \
        --search-path ~/Dropbox/ \
        > ~/.cache/files/documents_downloads_resources
end

• IPFS -- & similar content addressable storage systems
  • Tahoe-LAFS (least-authority file system)
  • IPFS -- 10 years old now

Name data networking system (prev academic lit).
IP address -- [to a "location"].
URL / URI / URN -- Uniform Resouce... "Location" / "Identifier" / "Name"
hash-based name -- don't have to care about as much where you get data / who you get it from, 

-- cubo (go ipfs)
What thrived? What were takeaway lessons?
Worked on NFT (moxie blogpost) -- without a cryptographic commitment.  As "hash" of media -- good. As pointer to location -- "bad".

• DID WG @ W3C.
  • recommend, skip: w3c did-core

• indy user agent projects
  • ladybird
  • peersky?
  • Agregore browser Mauve

• • beaker browser -- stalled out now.

• delegatable permission format -- identifier to identifier
  • called "Z-caps", similar to macaroons

• Jane Street podcast -- Signals & Threads
  • recent topics include: development on MirageOS Unikernel, Xen hypervisor
  • MirageOS -- unikernel -- Xen lineage, conceptually

• llm haters group / +
• pulse of group -- llms to generate code -- what's the story here -- llm haters
  • small scripts --
  • architecting (even multi-model). & "Spec-driven development"
    • llms not keeping track of --
