Santa was playing and losing yet another game of Yahtzee with Mrs. Claus and the elves when a thought occurred to him: why don’t you get points for rolling the first 5 digits of the Fibonacci sequence (1, 1, 2, 3, 5)? For that matter, why isn’t there a mathematician’s version of Yahtzee where you get points for rollingContinue reading “Day 12 – Mathematician’s Yahtzee”

Datastar is a hypermedia systems library in the same tradition as htmx, Unpoly, Alpine AJAX, and Hotwire‘s Turbo.

Day 10 – Santa’s Finance Department
Cron Meets Raku The Finance Department’s computers had been converted to Debian Linux with Rakuized software along with all the other departments at the North Pole headquaters, and its employees enjoyed the Windows-free environment.

While doing a small visit to the corridors, she ran into Nanunanu, one of the IT elves.

Day 5 – Tools for Gnome::Gtk4
A short while ago, Santa Claus came to me for a short visit to drink a cup of tea together. That was very pleasant, but I had the idea that there was something more, knowing that he is always busy, especially these days. After some time, he came forward and said that the elves hadContinue reading “Day 5 – Tools for Gnome::Gtk4”
Day 4 – Gift yourself a merry little PDF journal
I wanted to give myself the Xmas gift of a 2026 pdf journal this year. I had grand plans to create a fully fledged library for doing this, but ironically enough I just wasn’t that organised! But courtesy or the comprehensive PDF api by dwarring https://raku.land/zef:dwarring/PDF::API6 and with help from tbrowder’s Date::Names for human datesContinue reading “Day 4 – Gift yourself a merry little PDF journal”
Day 3 – Christmas Crunching Part I
“Advent is here”, the buzz was all around, the elves were getting nervy and the reindeer pawed the ground. Rudolph (for it was he) stood in quiet contemplation as the elves increased their pace and the din grew ever louder.
