🕰️ Historical projects (from Higher School Preparatory Class)

WARNING: These old projects are written mostly in french language.

• DES-Crypto-CaML – In 🇫🇷 language
  Copyright © 2008 Hermès Bélusca-Maïto and Guillaume Frèche, Lycée Pierre De Fermat.
  An implementation of the DES cryptographic algorithm, written in the CaML language, with an interactive GUI demonstration that allows choosing what to encrypt/decrypt, as well as choosing different parameters. This was made as part of a mathematics/computer programming project.

• CamlCAS – 🇬🇧 and 🇫🇷 languages
  Copyright © 2008 - 2009 Hermès Bélusca-Maïto, Lycée Pierre De Fermat.
  A simplistic computer-algebra system (CAS), written in the CaML language. Its main purpose is to perform symbolic integration of multivariate rational functions over the reals or complex fields, with the Risch algorithm:

  • Square-free factorization, using either the Yun or the Tobey-Horowitz (see e.g. arXiv:1306.4342) algorithms;
  • Partial fraction decomposition;
  • Hermite reduction for the rational part;
  • Rothstein-Trager method for the logarithmic part.

⚡ Recent projects

• MathematicaSSHRemote
  Copyright 2018 Hermès Bélusca-Maïto, under the GPL-2.0+ license.
  A Mathematica package that implements remote kernels launch through tunnelled SSH connections.

• pdf-LaTeX Compilation Script
  A quick & dirty compilation script for LaTeX, written in CMD batch (Windows-only).

  Syntax:
  pdflatex.cmd build[-fast] name_of_tex_file
  pdflatex.cmd clean [name_of_tex_file]
  

👨‍💼 Public Contributions
