Santa’s Sad

Santa is really sad to see only 3 slots of the 25 of the 2024 Raku Advent Calendar have been claimed so far. Surely there must be people reading the Rakudo Weekly that have written something in the Raku Programming Language (such as an ecosystem module, or a handy script used in every day production) and who are proud of their work? Proud enough to write a blog for the Raku Advent Calendar for it? “Yeah”, Santa mumbled, “there must be!”.

Elizabeth’s Corner

Elizabeth Mattijsen was reminded about an X-Y problem, and wrote a blog post about it: A path to paths.

Hillel’s Corner

Hillel Wayne (of “A Language For Gremlins” fame) wrote another nice blog post. This time fully dedicated to the Raku Programming Language: Five Unusual Raku Features, describing it as a laboratory for language features (HackerNews, lobste.rs, /r/rakulang comments).

Anton’s Corner

Anton Antonov has published another nice video about neat examples of the use of their Graph module: Graph neat examples in Raku (Set 2) (/r/rakulang comments).

Steve’s Corner

Steve Roe was reminded of their interactions at the last London workshop, and put their presentation about the production logic they use for migrating WordPress sites in writing: raku & perl – A Reconciliation.

Timo’s Corner

Timo Paulssen produced a nice ASCII animation, showing their progress on their upcoming Hexdump::Async module.
