- 2025: Rust & more visualizations
- 2024: Rustaceans assemble! Focusing on faster solutions this year. Caching in rust feels quite clumsy compared to python's
@lru_cachedecorator. - 2023: Going with rust again!
- 2022: Using this as an opportunity to learn rust. I did use python on some of the puzzles where I was racing against colleagues. :D
