Tyler Limkemann returns (after an extended absence) with a very nice article about how they used the Raku Programming Language to solve Wordle challenges. With plenty of code and theoretical background.

Alexey’s Corner

Alexey Melezhik invites the Raku (and devops) community to comment on the design of the SparkyCI DSL, the Continuous Integration testing running on Sparky.

Wenzel’s Corner

Just before the Weekly’s deadline, Wenzel P.P. Peppmeyer published a blog post about yet another way of using subsets, inspired by Fernando Correa de Oliveira‘s work on Red (the ORM of choice in the Raku Programming Language).

say (1..5).head(*-2);  # (1 2 3)

And conversely, you can do the same with the .tail method, to limit from the beginning:

say (1..5).tail(*-2);  # (3 4 5)
