Project Notes

Bitdevs WhatsApp

  • Public target group for Bitdevs announcements: Bitdevs Brasília
  • Group JID: 120363221288772343@g.us
  • Do not send Bitdevs public announcements to:
    • BitDevs BSB - Organização
    • Bitdevs Hosts Brasil
  • User explicitly confirmed on 2026-04-16: the correct destination is Bitdevs Brasília, not the other groups.

Cross-Post Groups

  • Bitdevs Brasília -> 120363221288772343@g.us
  • Web3 Brasília -> 120363045416474611@g.us
    • Local group name may appear as web3 - Brasília.
  • Mensa DF -> 556184020538-1393452040@g.us
    • Local group name may appear as Mensa DF Regional.
  • MB | Bitcoin -> 120363295670541188@g.us
    • There are duplicate MB | Bitcoin groups in the local DB; prefer the one above because it is the more recent active chat.

Bitdevs Signal

  • Public target group for Bitdevs Signal announcements: Brasília BitDevs
  • Group ID: pvnObTw2yKtcxxaqn2vityymra0e+kmQU7UZVruXnNo=
  • Confirmed from the local signal-cli group list on 2026-06-12.
  • Use this concrete group id for Signal sends; do not infer a recipient from the public invite link alone.
  • Latest square banner used for WhatsApp previews:
    • /Users/breno/Downloads/_Banner quadrado Convite Bitdevs BSB (7).png
  • Latest horizontal banner found alongside it:
    • /Users/breno/Downloads/Banner Convite Bitdevs BSB (30).png
  • The square version is a good default for WhatsApp group sends.

Sending Workflow

  • Prefer the square banner for WhatsApp group sends:
    • /Users/breno/Downloads/_Banner quadrado Convite Bitdevs BSB (7).png
  • Use the release binary in ~/.local/bin/wacli; Homebrew may still resolve to the broken 0.2.0 build if the shell PATH is wrong.
  • Before sending, validate the active binary:
    • hash -r && which wacli && wacli --version
  • Smoke-test connectivity before group sends:
    • wacli sync --once
  • Send the banner + caption to a group:
wacli send file \
  --to "<group-jid>" \
  --file "/Users/breno/Downloads/_Banner quadrado Convite Bitdevs BSB (7).png" \
  --caption $'Na próxima quinta, 23/04, tem mais um Bitdevs, onde conversamos sobre os aspectos técnicos do Bitcoin. Não se esqueçam de fazer seu cadastro gratuito e convidar seus amigos interessados. Haverá pizza!\n\n🗓 23/04\n📍 UnB - Faculdade de Tecnologia, Sala BT-52/15\n🕒 19h\n🔗 https://app.evento.so/e/evt_Vxg654Hj8g5vJdmd'

Source of Truth

  • Confirm event details from the event page and the newest banner in ~/Downloads.
  • For this event, the banner confirmed:
    • date: 23 de Abril
    • time: a partir das 19h
    • location: UnB - Faculdade de Tecnologia, Sala BT-52/15

Agenda Sources

  • Every agenda topic must link directly to the specific source item or section that supports its title. For newsletters and release notes, use the relevant anchor instead of linking to the publication’s front page.
  • Do not use a generic list of recent commits or pull requests as the source for a topic. A topic must link to the specific commit, PR, issue, post, release section, or discussion being proposed.
