Vadim Belman has kicked off a series of blog posts about advanced Raku subjects, but for beginners! And what a kick off it was! With already three blog posts to savour:
Looking forward to future instalments!
Alexey Melezhik has also started a series of blog posts, called RakuOps, about how you can use Raku in daily DevOps tasks. The first episode is called: How to Build Docker Containers Using Raku and Sparrow (/r/rakulang comments).
Grant Extension Request
Jonathan Worthington has requested an extension of the Raku Performance and Reliability Engineering grant. Please leave your thoughts about this requests with that request (/r/rakulang comments).
A Thousand Times Faster
Timo Paulssen has published a blog post about their grant work called: How would you like a 1000x speed increase. It’s about how tracking allocations in the profiler can be done much better (/r/rakulang comments).
Mark Carter returns for another week with a blog post that’s about grammar hints about creating a templating system (/r/rakulang comments).
Close, But Yet Another Two
Wenzel P. P. Peppmeyer almost didn’t make it to publish 2 blog posts this week, but the second one appeared just for the Rakudo Weekly News’ deadline. As usual, each addressing some feature or quirk of the Raku Programming Language.
- Piping made easy (/r/rakulang comments)
Jeff Goff’s Blog Posts
Andrew Shitov took to the Wayback Machine, and managed to recreate the blogs that Jeff Goff (aka DrForr) has written in the period 2015-2019 (/r/rakulang announcement).
The entries for Challenge #67 that have Raku solutions:
- Weekly Challenge #67 by Luca Ferrari.
- Numbers and Letters with Raku by Arne Sommer.
- Weekly Challenge #67 by Javier Luque.
- Weekly Challenge #67 by Shahed Nooshmand.
- Weekly Challenge #67 by Mohammad S Anwar (videos task #1, task #2).

- Combinations in Raku by Andrew Shitov
- Number Combinations and Letter Phone by Laurent Rosenfeld.
- Weekly Challenge #67 by Jaldhar H. Vyas.
- Combinations by Donald Hunter.
Andrew Shitov provided a complete index of solutions they made to previous challenges. And Challenge #68 is up for your perusal!
Most of the work of the past week has been done behind the scenes in branches again: Stefan Seifert worked on in-process pre-compilation, Jonathan Worthington and Timo Paulssen worked on the new dispatch mechanism and the RakuAST grant, Elizabeth Mattijsen abandoned (at least for now) their work on refactoring the way
Match objects are populated.
- Timo Paulssen added various constant folding optimizations in MoarVM.
- Elizabeth Mattijsen made reading a single byte with
IO::Handle.readabout 3x as fast and fixed an improper implementation of
Supply.tail(*-10)semantics. They also made
List.permutationsbetween 23x and 85x faster, after a spot by Jan-Olof Hendig.
- And a few other fixes, optimisations, and improvements.
