+# Git repositories
+
+You can find all my git repositories at
+[git.tronto.net](https://git.tronto.net/) or on
+[my github page](https://github.com/sebastianotronto).
+You can clone a repository with `git clone https://git.tronto.net/[NAME]`.
+
+## Tutorials
+
+* [fmctutorial](https://git.tronto.net/fmctutorial): an in-depth
+  tutorial for the Rubik's cube *Fewest Moves Challenge*, or FMC.
+
+## Programs and scripts
+
+I started writing code in 2005, with a toy programming language called Dark
+Basic first and with Java shortly after that. In the past I enjoyed learning
+different programming languages (C++, J, Python...), but I have recently found
+more pleasure in writing software in plain C.
+
+* [nissy](https://git.tronto.net/nissy): A Rubik's cube solver,
+  intended primarily as a tool for practicing FMC.
+* [sdep](https://git.tronto.net/sdep): A minimalistic
+  "date+event" line parser. Can be used in combination with some shell scripts
+  as a reminder / calendar application.
+* [scripts](https://git.tronto.net/scripts): Various scripts
+  for Unix-like systems.
+
+## Math courses and programs
+
+Here are some scripts I wrote and lecture notes for some courses
+I taught at the [University of Luxembourg](https://wwwen.uni.lu)
+(2018-2022).
+
+* [mathsoftware](https://git.tronto.net/mathsoftware): a full
+  course (3 ECTS) on LaTeX and SageMath.
+* [preplogic](https://git.tronto.net/preplogic): notes and
+  exercises for two introductory lectures on elementary logic.
+* [kummer-degrees](https://git.tronto.net/kummer-degrees): a
+  SageMath script for computing the degrees of Kummer extensions of the

+# Research
+
+After obtaining a bachelor degree in Trento in 2016 I have completed the
+[ALGANT](https://algant.eu) Master Program (Milano and Leiden), with special
+focus on number theory and algebraic geometry. I am now working on my PhD
+under the supervision of [Antonella Perucca](http://antonellaperucca.net) and
+[Peter Bruin](https://www.math.leidenuniv.nl/~pbruin).

+# Speedcubing
+
+![Me solving a Rubik's cube during an official competition](cubing.png "Me solving a cube")
+
+I have been practicing [speedcubing](https://en.wikipedia.org/wiki/Speedcubing)
+since 2008, and since 2011 I have competed in 49 officially recognized
+[WCA](https://www.worldcubeassociation.org) competitions. I currently hold the
+world record for the single best result in the *3x3x3 Fewest Moves* event
+(16 moves), and some national records in different blindfolded events. I am
+also the leader of the WCA Disciplinary Committee. You can see all my official
+results [here](https://www.worldcubeassociation.org/persons/2011TRON02).
+
+If you are interested in Fewest Moves solving, check out my
+[FMC Tutorial](https://github.com/sebastianotronto/fmctutorial). I also
+upload irregularly on 
+[my YouTube channel](https://www.youtube.com/c/SebastianoTronto), but most
+videos are just me solving the cube.
