rust Marching Squares in Rust+WebAssembly After previous forays into creating fancy backgrounds using JavaScript, I've been playing with an implementation of one of my favourite computer graphics algorithms in Rust. It seems that my second, more efficient implementation
rust Cross-compiling Rust Code using GitLab CI I've been excited to learn the Rust language for two years now since it compiles the performance properties of statically-compiled languages with modern language ergonomics (and allows you to parallelize things you normally
programming A bot that learns how you play rock-paper-scissors As a small project, I wrote a bot for learning player patterns when playing rock-paper-scissors using a first-order Markov chain. This is definitely not the first time someone has had this idea, but

python Inspecting multidimensional C/C++ matrices by putting NumPy into GDB Developing numerical programs in C, C++ or Fortran or even just fast C extensions like in my previous post, the chance of introducing a bug increases as complexity increases. One of my favorite
analyses The most popular random seeds When developing programs that rely on some sort of randomness, it is often a good idea to make the random number generator behave more deterministically. For example, you could have a procedurally generated
hpc Fast Interstellar Travel with NumPy and C I absolutely love Python (and NumPy!) for the flexibility it gives me in quickly building up complex data structures and programs to arrive at interesting solutions. Still, sometimes handling larger amounts of data
