This document (notebook) describes three ways of making mazes (or labyrinths) using graphs. The first two are based on rectangular grids; the third on a hexagonal grid.
Day 23 – A Day Late and A Fish Short
Hello again! I return during this week of winter solstice to tell you about my experience participating in the Langjam Gamejam. I planned to use Raku, partially so that you could have an advent blogpost to read today, but also because Raku’s builtin support for grammars ensure that I would not get stuck when writingContinue reading “Day 23 – A Day Late and A Fish Short”
Day 22 – Numerically 2026 Is Unremarkable Yet Happy
This document explores the properties and relationships of the integer 2026. It is classified as a semiprime and a happy number, with 365 serving as one of its primitive roots.

Day 21 – A Terminal’s Tale

(TUI == Text User Interface, i.e. apps like tmux, vim, k9s)For those that wonder, there is a yet to be finished TUI debugger application I’m working on, theContinue reading “Day 21 – A Terminal’s Tale”

Day 18 – Hallo, Wêreld!

Lizzybel was walking the corridors of North Pole Central when Steve, the Physics Elf, came up to her. “Have you seen my issue on this very nice module of yours?”, he asked. “Oof, I guess I must have missed that, sorry!”, said Lizzybel, while thinking to herself “I really should look more at my modulesContinue reading “Day 17 – An issue with evaluation”
Day 16 – Melian and the Helpers of Evergreen
by Sawyer X Operation Evergreen began quietly that winter. Santa had announced it as a workshop-wide initiative to improve the speed and efficiency of analytics across every team (logs, metrics, scheduling, routing, and storage). The elves who maintained the Workshop’s growing systems found themselves gathered around long benches, examining slow queries, performance charts, and theContinue reading “Day 16 – Melian and the Helpers of Evergreen”
Day 14 – Taming Concurrency
Hello everyone and a merry advent time! Today I’d like to show case a neat little mechanism that allows building concurrent applications without having to worry about the concurrency much. I’ve built this tool as part of the (yet to be released) Rakudo CI Bot. That’s a middle man that watches GitHub for things toContinue reading “Day 14 – Taming Concurrency”
