On this page, you can find a few code projects.
C Compiler : Here is a compiler for the language C written with Abel Douzal during our years in ENS. The zip archive can be downloaded here. There is a readme inside which explains how to use it.
Baby OS : Here is a basic OS written in C and assembly. The zip archive can be downloaded here. There is also a readme inside explaining how it works.
Spectral radii in free groups : Here is a little Python project made to optimize the computation of spectral radii of convolution operators acting on the free group algebra. It crucially uses assymptotic freeness of random matrices, see this paper for details.
