Arseny Kapoulkine (h/t John Regehr) wrote a nice exploration of how LLVM from 2010 compares to the performance we get today. I decided to try out an old version of Racket, and compare performance to a modern version.

The versions I compared were:

• MzScheme 206p1, released January 2004
• Racket 8.0.0.4, compiled February 2021 (using the Chez Scheme backend)

I measured exactly one benchmark, a mandelbrot set computation from the Computer Language Benchmarks Game, using the implementation in the Racket repository. Of course, that code won't run on v206p1, so I modified it to avoid new features of Racket. The modified version is below.

Of course, many of the features that have been added make the program faster, so it's important to compare with the performance of the modern code. There's even a [parallel version](https://githu

CUSTOM GAME ENGINES: A Small Study

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like Unreal or Unity for their games (or that's what lot of people think) because d

raylib: 6 years of fun

raylib has been in development for more than six years now, it has been an adventure! I decided to resume how it was my personal experience working in this free and open source project for such a long time. Just note that the following article explains raylib from a personal point of view, independently of the technical aspects and focusing on the personal adventure; for technical details on raylib evolution, just check raylib history and raylib changelog.
