Good news from the FOSDEM organizers: there will be an online Raku DevRoom at FOSDEM 2022. Please stay tuned for more information on how to make sure you can get a presentation in. And of course, this should not prevent you from submitting a presentation to any of the other tracks to spread the word of the Raku Programming Language. Such as the Declarative and Minimalistic Computing track to name but one example.

Still not so happy on the M1

Steve Roe continues their journey with Raku on their new M1 laptop with MacOS Monterey in “Raku at the Monterey Docks (Part II)“. Comments and suggestions are still welcome!

Wenzel’s Corner

Wenzel P.P. Peppmeyer wrote two blog posts this week, inspired by recent events.

Flavio’s Corner

Flavio Poletti wrote two blog posts inspired by the Weekly Challenge:

Adoptions

JJ Atria has adopted the Jonathan Scott Duff‘s AI::FANN distribution in the past week, and Elizabeth Mattijsen has adopted Timothy Totten‘s HTTP::Status distribution. Check out the Raku Module Adoption Center if you would like to adopt a module, and you don’t know which one!

Still coming closer!

Only a few days to go, and it’s Advent Calendar time again! Make sure you get a slot in this year’s Advent Calendar for the Raku Programming Language, by adding your blog post proposal to the preliminary list of authors and articles!
