Programming

The problem When we write our programs or libraries, usually we ship to the end user a packaged binary. If a user wants to report a bug or ask for a feature, one of the most important information to have is “which version of the software are you using ?” Since as any good programmer you likely use a source code control system, you should not rely only on the numeric version, but it’s practical to include also the git commit hash of the software you are actually shipping. ...

Nostalgia time! Today I decided to play with Raylib and the Crystal Programming Language. Technically speaking, the “plasma” effect is just a two variables noise function. Some used Perlin Noise, others the Diamond-square algorithm. A more interesting pattern can be obtained with trigonometrical functions, as explained here. The interesting part here is the easyness of graphics programming in a Linux environment with a high level, yet performant and statically typed programming language. The code is straightforward and a simple port of the original ‘C’ source, I got surprised how the Crystal Language is easy to use and produces a quite fast native binary. If you want to check it out, you can find on my github account; in the meantime enjoy the mandatory video/screenshot :) ...

Once in a while I like to play with Advent Of Code problems 🎄. Today I decided to tackle an easy one and, since the answer was almost trivial to find, I wanted to go deeper and understand how to measure and improve the performance of the solution. ...

Inspired by a tweet from a fellow developer, I decided to take a look at Karax, a nifty framework for developing single page applications in Nim. After following the basic tutorials and examples, I searched for something more complex and found very sparse documentation, so I’ll write my findings here. As usual, the complete source code is on my github repo, where you can find also a working live demo. In this example I wanted to experiment with the component pattern, and create a stateful module that can be reused. So I modeled a nim clock object, here the source: ...
