Day 18 – Hallo, Wêreld!
by habere-et-dispertire The first elf language is the sharing of emotions. Next comes their mother tongue. When elves start speaking their first programming language, then they are already onto their third language! Santa imagines raku draws inspiration from many principles of Unix philosophy In particular, localization of raku plays into the robustness principle. When writingContinue reading “Day 18 – Hallo, Wêreld!”
Day 17 – An issue with evaluation
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 15 – An expression language for Vixen
#raku-beginners: korvo: Hi! I’m trying out Raku in stead of META II for a toy compiler. (5 minutes later) korvo: I’m merely trying to compile a little expression language because my angle of repose has slightly increased, and multiple folks have recommended Raku for parsing and lightweight compilers. (20 minutes later) korvo: [T]hanks for aContinue reading “Day 15 – An expression language for Vixen”
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”
Day 13 – Christmas Crunching Part II
Christmas is nearly on us, 10 shopping days to go. Things at the pole were gathering pace, with so much left to do. Rudolph (him again) was pacing up and down, mashing his cheroot. He cast his mind back to the App::Crag calcs he had done last time – sure all the distances, times andContinue reading “Day 13 – Christmas Crunching Part II”
Day 12 – Mathematician’s Yahtzee
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”
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. However, an inspection by a firm hired to evaluate efficiency practices found some room for improvement. Much of the work dayContinue reading “Day 10 – Santa’s Finance Department”
Day 8 – HARC The Herald Angels Sing
Rudoph had long wanted wanted to write a website – he longed to share his hobbies and opinions with all the children, so that they wouldn’t just think of him as a first class pilot and navigator. He knew about Raku and he had skim read some information about Cro and Humming-Bird. But, being quiteContinue reading “Day 8 – HARC The Herald Angels Sing”
