  3. crystal-docker-quickstart

    A project template for quickly working with the Crystal programming language in a Docker container, no installation needed.

    This is great Serdar.

    As an alternative to Chapter 2 I’ll also share https://github.com/compumike/crystal-docker-quickstart my project template which lets you get a Crystal (currently 1.6.2) dev environment running with just Docker. Good for kicking the tires, which is what I think your audience is probably wanting to do! And then eventually can install a binary package as you suggest.

  4. adventofcode

    Advent of Code solutions of 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023 and 2024 in Scala (by sim642)

    With advent of code coming up I'm torn between Kotlin and maybe Crystal.
