2021.51 Transiting

Arne Sommer was inspired by public transport developments in their native Oslo. This resulted in a cool new module Transit::Network, but also a serious blog post: Planning Public Transportation with Raku (/r/rakulang comments), a semi-serious Reindeer Express blog post, and a followup on the original: Bugs R Us – A Transit::Network Update (/r/rakulang comments). And Arne was still being able to find the time to do a blog post for the Weekly Challenge: Stealthy Calculator.

Adventing Continues

It’s also still Advent Calendar time! These are the entries of the past week:

If you’re up to it, there is still one slot available!

FOSDEM 2022 CFP expanded

The Call for Participation for the Raku DevRoom at FOSDEM 2022 is still open! The deadline has been moved to 31 December! This means you will have more time to consider your Raku presentation as there is still time to submit your proposal (comments on /r/rakulang: 1, 2)!

Fez Orgs Arrive

Tony O’Dell has implemented organizations in the zef ecosystem, which allow multiple people to be responsible for a distribution (which will be handy when moving Raku Community Modules to the zef ecosystem). Tony explains in Fez Orgs – A Winter Solstice Miracle!


Tomasz Wegrzanowski decided to take the Raku Programming Language for a spin in episode 26 of the 100 Languages Speedrun. This resulted in some discussions on /r/rakulang and in the comments section of the blog post itself.

NNFS with Raku

Khalid Elboray has started a series of implementing Neural Networks with Raku. The first part: NNFS with Raku, was already published three weeks ago, but had somehow escaped detection by yours truly. My apologies!

Flavio’s Corner

Flavio Poletti was again very inspired by the Weekly Challenge and the Advent of Code 2021:


Weekly Challenge #144 is available for your perusal.
