In June 2026 I have been offering a revised version of this lecture as HGS-HIRe power week. At the end of each session, the material has been revised and some typos have been fixed. All the lecture material is attached here in a unique PDF file (including exercises). Hyperlinks and bookmarks should work as in the files of the single days. 🔝 😎 All solutions to exercises and practice sessions can be found in the repository. A Bash implementation of the Conway's Game of Life has also been uploaded next to the solutions of the practice sessions. 😏
