Introduction

PUZ is a file format commonly used by commercial software for crossword puzzles. There is, to our knowledge, no documentation of the format available online. This page (and the implementations) is the result of a bit of reverse engineering work.

HVM3's Optimal Atomic Linker (with Polarization)

Atomic linking is at the heart of HVM's implementation: it is what allows threads to collaborate towards massive parallelism. All major HVM versions started with a better atomic linker. From slow, buggy locks (HVM1), to AtomicCAS (HVM1.5), to AtomicSwap (HVM2), the algorithm became simpler and faster over the years.

On the initial HVM3 implementation, I noticed that one of the cases on the atomic linker never happened. After some reasoning, I now understand why, and

Beginner's Guide To Console Input In C#

Note: I recommend reading this gist in order because Examples 1-6 build on each other.

Example 1: Getting Console Input With Console.ReadLine
_{How to get console input.}

Example 2: Parsing The Console Input From String To Int32
_{How to convert the console input into a numeric value.}

Example 3: Validating Console Input With Int32.TryParse
_{How to validate numeric input to prevent bugs in your code.}

[Example 4: Looping Until User Provides Valid Input](https://gist.github.com/ZacharyPatten/798ed612

Then mathematical neatness became a goal and led to pruning some features from the core of the language.

— John McCarthy, History of Lisp

If you prefer programming languages with a tidy and tiny core, you're in for a treat. This article drills down to the singleton primitive at the heart of Raku's metamodel ("model of a model") of a model of computation ("how units of computations, memories, and communications are organized")¹.

The reason I've written this article

It began with u/faiface's reddit post/thread "I'm impressed with Raku"². One of their sentences in particular stood out for me:

Architecture

Use Onion architecture
- Dependencies go inwards. That is, the Core domain doesn't know about outside layers
Use pipeline model to implement workflows/use-cases/stories
- Business logic makes decisions
- IO does storage with minimal logic
- Keep Business logic and IO separate
Keep IO at edges
