Last Week's Minutes

• Announcements
  • micro:bit rewrite of discovery book nearing completion!
• Discovery book
  • Discussed how to organise multiple books
  • Perhaps one subfolder per book, all in the same repo, with a landing page that links to each book
  • The new micro:bit becomes the main and recommended book, but we keep hosting the old one for people with an f3
  • A new risc-v version of the book can be written and live alongside these two
    • Perhaps using the Longan Nano?
    • HiFive inventor?
    • The risc-v version can be "extension chapters" to the main discovery book, covering risc-v without recovering the introductory material
• Commercial involvement:
  • We sometimes get people from companies asking how they can help; what can we do to get them involved?
  • https://github.com/rust-embedded/awesome-embedded-rust/issues/337 asking about new testimonials from embedded users to help demonstrate Rust's industrial use
  • To discuss next week
