This Saturday (3 December 2022 at 20:00 UTC), Vadim Belman will be giving the first online class about Rakudo core development (/r/rakulang comments). Requirements are a working knowledge of the Raku Programming Language, use of git and Github, and a willingness to self-learn things. It will be a kind of seminar where things may significantly divert from the initial plan.

Anton’s Corner

Anton Antonov did another of their blog post / YouTube video combos with Interactive Mermaid diagrams generation via Markdown evaluation (video, /r/rakulang comments).

San Francisco Raku Study Group

There will be an online SF Raku Study group at 9 GMT on 18 December (password: 4RakuRoll), the meeting on the 4th of December has been cancelled due to scheduling conflicts.

Steering Council

The minutes of the November 26th, 2022 meeting are available.

Also, the deadline for the acceptance of nominations for the Rainbow Butterfly Award has been moved to the 8th of December. Please consider who you would like to receive the Rainbow Butterly Award 2022 by sending your nomination by email to: rainbow@raku.org .

Special offer on Raku (e)Books!

It looks like Springer Verlag still has the special offer on two Raku Books, each at about 10€ / 10$, and the ebook at about 7€ / 7$! It is unclear how long this offer will last! This would make an excellent Christmas present!

Winding down

Amazing to see how much interest #RakuLang is generating on Mastodon! And a new name in core development. And that while many people are preparing their entries for the Raku Advent Calendar!

This week’s picture is of a treetop in the setting sun! To remind us Ukraine is still fighting the Russian aggression. Слава Україні!  Героям слава!

In the meantime, please keep staying safe, keep staying healthy, and keep up the good work!

If you like what I’m doing, committing to a small sponsorship would mean a great deal!
