# My git repositories
In this page you can find all my public git repositories. It is a collection
of programs, tutorials, configuration files and more. All my repositories
are also mirrored on [my GitHub page](https://github.com/sebastianotronto).
Here are some highlights; for a full list, see [the index](../).
## Programs
* [ancient-projects](../ancient-projects) is a collection of my early coding
projects (2006-2010), mostly written in Java.
* [nissy-core](../nissy-core) is my biggest hobby project. It is a Rubik's
cube solver focused on finding optimal solutions. It uses a standard A*
search method supported by a custom set of pruning tables. It can be
included as a library in your C, C++ or Python projects, and it can build
to [WebAssembly](https://en.wikipedia.org/wiki/WebAssembly).
* [nissy-classic](../nissy-classic) is another Rubik's cube solver, focused
on assisting the user in exploring [domino
reduction](https://www.speedsolving.com/wiki/index.php/Domino_Reduction)
solutions.
* [minesweeper](../minesweeper) is an unremarkable attempt at building a
graphical application with [raylib](https://www.raylib.com/) and
[Hare](https://harelang.org/).
* [zmodn](../zmodn) is a small library for [integers modulo
N](https://en.wikipedia.org/wiki/Modular_arithmetic) written in
modern C++. I also ported it to Rust, see [zmodn-rs](../zmodn-rs).
## Configuration, scripts and website sources
* [config](../config) contains the configuration files (a.k.a. dotfiles) for
my Alpine Linux laptop setup, as well as a collection of scripts for my
daily desktop use.
* [sebastiano.tronto.net](../sebastiano.tronto.net) contains the source code
(Markdown) for [my personal website](https://sebastiano.tronto.net),
including template HTML and CSS files, and build scripts.
* [cgit-config](../cgit-config) contains the configuration files for this
cgit page.
## Programming challenges
* [aoc](../aoc) contains my solutions to (some of) the [Advent of
Code](https://adventofcode.com) problems.
* [cses](../cses) contains my solutions to (some of) the
[cses.fi](https://cses.fi) problems.
## Math
* [ecm](../ecm) is a Python implementation of the
[Elliptic Curve factorization
Method](https://en.wikipedia.org/wiki/Lenstra_elliptic-curve_factorization)
that I have used for a couple of
[talks](https://sebastiano.tronto.net/talks).
* [kummer-degrees](../kummer-degrees) is a
[SageMath](https://www.sagemath.org/) library to compute
the degrees of [Kummer extensions](https://en.wikipedia.org/wiki/Kummer_theory)
over the rational numbers.
* [mathsoftware](../mathsoftware) containes slides, exercises and references
for the course Mathematical Software that I taught at the
[University of Luxembourg](https://uni.lu) in the Fall of 2021.
* [arithmeticbilliard](../arithmeticbilliard) contains code for [Arithmetic
Billiard](https://en.wikipedia.org/wiki/Arithmetic_billiards) simulations.
* [platonicsolids](../platonicsolids) is a collection of Latex files for
drawing [Platonic solids](https://en.wikipedia.org/wiki/Platonic_solid)
with [TikZ](https://en.wikipedia.org/wiki/PGF/TikZ).
## Tutorials and proofs of concept
* [fmctutorial](../fmctutorial) is my tutorial for
[solving the Rubik's Cube](https://sebastiano.tronto.net/speedcubing)
in as few moves as possible. You can download the pdf from
[fmcsolves.cubing.net](https://fmcsolves.cubing.net).
* [emscripten-tutorial](../emscripten-tutorial) contains the codes for
the example of [a blog post of
mine](https://sebastiano.tronto.net/blog/2025-06-06-webdev) about
[WebAssembly](https://en.wikipedia.org/wiki/WebAssembly)
and [Emscripten](https://en.wikipedia.org/wiki/Emscripten).
* [python-c](../python) is a minimal example of Python module written in C.
