Two days of just stuff about the Raku Programing Language at the second Raku Conference this weekend. Online only, alas. Hopefully in person next year! Ah, and if you would like to give a lightning talk, there’s still room for that! And don’t forget to register if you haven’t already!

Podlite server

Alexandr Zahatski, the author of Podlite (pod6 markup editor) announced Podlite-web, a lightweight starter for creating blogs/sites using nexjs and pod6 markup language (/r/rakulang comments). Intriguing usages and examples!

Anton’s Corner

Anton Antonov continues their work on Machine Learning, this week again with an extensive blog post, this time about Clustering analyses with the K-means and K-medoids algorithms, among many others! Good progress!

$ say (^5).map({ $_, $_ + 1 })
# ((0 1) (1 2) (2 3) (3 4) (4 5))

Well, actually in this case, it’s still a single value, which happens to be a List. However, you can really return multiple values, as long as you put them in a Slip.

$ say (^5).map({ ($_, $_ + 1).Slip })
# (0 1 1 2 2 3 3 4 4 5)

A Slip is a List that automatically flattens into an outer List (or other list-like container or iterable). You can also use the prefix pipe to create a Slip. In the above example, that would be: |($_, $_ + 1).

Winding down

A record week in Raku module land! Quite a number of new modules, and updates (with Jonathan Stowe updating and moving all of their modules to the zef ecosystem!).

This week’s image background again there to remind us to support Ukraine in their and our fight against the Russian aggression. Слава Україні!  Героям слава!

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

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