  • SonarLint - Clean code begins in your IDE with SonarLint
  • InfluxDB - Collect and Analyze Billions of Data Points in Real Time
  • Mergify - Updating dependencies is time-consuming.
  • Charm

    Source code for the Charm programming language (by tim-hardcastle)

    I'm not sure what counts as cool. It's just dogfooding at the moment. I did a bunch of other languages (only the BASIC and the Forth are up to date with the current version of the language I think), and I did a tiny adventure game (and used it as the basis for a tutorial).

  • advent-of-code-jq

    Solving Advent of Code with jq

    I used the Advent of Code 2022 problems as a way to test out my Jactl language. Have solved them all and written a blog post about most of them. It was a lot of fun to actually use my own language to solve "real world" problems as opposed to simple tests and it did lead to a few minor improvements such as using negative indices to express an offset from the end of a collection. E.g. x[-1] instead of x[x.size() -1] to access the last element.

  • Innf107

    The build system for my blog is written in polaris.

  • polaris

    A functional programming language with shell scripting capabilities (by Innf107)

  • flora

    A pure embeddable functional programming language with algebraic effects and direct access to evaluation environments (by Innf107)

    In fact, I'm in the process of adapting the curently quite ad-hoc templating system to use another language of mine right now.

  • openflow

    A ventilation system built around Itho Daalderop's DemandFlow system, written in Inko (by yorickpeterse)

    A program that controls my central ventilation system. The code isn't as nice as I wanted due to having to avoid various bugs, but that's something I hope to fix in the near future.
