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. While 2026 may not stand out significantly in number theory, it offers a great opportunity to create elaborate visualizations that highlight some interesting aspects of the number.

Day 18 – Hallo, Wêreld!

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 writing to Santa,Continue 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 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 18 – Dissecting the Go-Ethereum keystore files using Raku tools

Generally the Ethereum (Web3) keystore file is a kind of container for the private key, it has the specific structure mostly related to encryption details. Actually you will not find the private key there as a plain text, but the keystore file has everything to decrypt the private key… with some tricks surely. When youContinue reading “Day 18 – Dissecting the Go-Ethereum keystore files using Raku tools”

Day 14: Trove – yet another TAP harness

Since the early Pheix versions, I have paid a lot of attention to testing system. Initially it was a set of unit tests – I tried to cover a huge range of units like classes, methods, subroutines and conditions. In some cases I have combined unit and functional testing within one .t file, like it’sContinue reading “Day 14: Trove – yet another TAP harness”

Day 23 – The Life of Raku Module Authoring

by Tony O’Dell Hello, world! This article is a lot about fez and how you can get started writing your first module and making it available to other users. Presuming you have rakudo and zef installed, install fez! Make sure that the last line is in your $PATH so the next set of commands all run smoothly. Now we can start writing the actualContinue reading “Day 23 – The Life of Raku Module Authoring”

Day 20 – Create beautiful text charts

Santa got his weekly gift-wrapping report from the Gift Wrapping department. It contained lots of numbers Every number corresponded to the gifts wrapped by every elf in the department in alphabetical order, starting with Alabaster Snowball, and continuing with Bushy Evergreen. But numbers don’t sing, and that made Santa not sing either. A simple wayContinue reading “Day 20 – Create beautiful text charts”

Day 12 – A long journey to Ethereum signatures

The Ethereum blockchain is essentially a transaction-based state machine. We begin with a blank state, before any transactions have happened on the network, and move into some final state when transactions are executed. The state of Ethereum relies on past transactions. These transactions are grouped into blocks and each block is chained together with itsContinue reading “Day 12 – A long journey to Ethereum signatures”
