   All desktop software calculators are wrong, so I had to build my own▲286

   A new calculator software cannot really bring attention (https://chachatelier.fr/chalk/) However, I wrote a full article explaining why I had to build something "new" that does not behave like usual desktop calculator softwares : TL;DR All "small" calculator softwares I know share the same design flaws. And the GUI is not the only stumbling block in their poor efficiency. Handling correctly numerical approximations - expected or not - is crucial to trust the results. It is usually not done in lightweight tools. It should. So I prove that if I could do it, OS manufacturers…

   Chebyshev approximation calculator▲278

   Hi everyone, here's a web app I made that generates code for efficiently approximating mathematical functions. This is useful when performance matters more than perfect accuracy, for example in embedded systems. The app uses Chebyshev expansions, which despite their theoretical depth result in suprisingly compact and readable code in practice. This code is generated for you and using it does not require any knowledge of the underlying theory. Source code and more info: https://github.com/stuffmatic/chebyshev-calculator
