Thankfully, there are many (too often unknown) gems, either built in the language/compiler or as third-party libraries. Some time ago, I introduced SymPy, which allows one to use symbolic maths in Python, and do things such as solving equations or integrating functions. In this article, I will introduce you another nice library, for Rust this time: uom (units of measurement). https://blog.nodraak.fr/2020/11/symbolic-maths-in-python/ Sat, 21 Nov 2020 00:00:00 +0000 https://blog.nodraak.fr/2020/11/symbolic-maths-in-python/ While working on my Moon lander guidance software, I am making several small prototypes to test ideas. One of them involves testing several control laws (of the acceleration), which implies quite a lot of manual calculations (to integrate to obtain the velocity and position). Doing these calculations by hand is tedious and error prone, and I thought about using a symbolic math program. Usually, a programming language can not manipulate variables without predefined values, but I found a Python library which can: SymPy. https://blog.nodraak.fr/2020/09/software-quality-notes-nested-for-loops/ Wed, 30 Sep 2020 00:00:00 +0000 https://blog.nodraak.fr/2020/09/software-quality-notes-nested-for-loops/ While working on Exomars as a software engineer, I was notified an issue to fix. I thought it was an interesting one, and spent some moments to think about how it could have been prevented in the first place. I care about code quality, and always try to build reliable software. For this purpose, I do not believe in rockstar developers (we are all fallible humans), but rather in (automatically enforced) processes and tools. https://blog.nodraak.fr/2020/07/rust-wasm-2-hello-world/ Tue, 14 Jul 2020 00:00:00 +0000 https://blog.nodraak.fr/2020/07/rust-wasm-2-hello-world/ For the second part of my Rust &amp; WebAssembly journey, I will write a basic hello world project. Note: you can jump to the demo by clicking here. This will give me the opportunity to demonstrate how to write a simple Wasm module in Rust. I will focus on a simple frontend and ignore the backend: no complicated GET or POST requests, no websockets, etc. This article will present how to build a simple game, such as Matt&rsquo;s Pont. https://blog.nodraak.fr/2020/06/rust-wasm-1-introduction/ Sat, 27 Jun 2020 00:00:00 +0000 https://blog.nodraak.fr/2020/06/rust-wasm-1-introduction/ In this article, I would like to talk about two technologies I&rsquo;ve been playing with recently: the Rust programming language and the WebAssembly standard. I&rsquo;ll start by presenting each of these two technologies and which problems they are trying to solve. Then, I&rsquo;ll explain what are the advantages of a Rust-powered Wasm module, and why it can be useful. Finally, I&rsquo;ll provide links to interesting documentation. WebAssembly Since many years, client side web applications, implemented in JavaScript, have been becoming larger and larger.
