Porting 100k lines from TypeScript to Rust using Claude Code in a month
I read this post “Our strategy is to combine AI and Algorithms to rewrite Microsoft’s largest codebases [from C++ to Rust]. Our North Star is ‘1 engineer, 1 month, 1 million lines of code.” and it got me curious, how difficult is it really?

Implementing a tiny CPU rasterizer (2024)
In the OpenGL course I'm teaching at a university, my students learn that the GPU uses something called rasterization to draw stuff on the screen. Then, I explain how — in theory — rasterization works, e.g. how would one write the code to draw a fixed triangle on screen. Of course, the GPU does that for us, but it is…

Memory layout in Zig with formulas
I was recently encouraged to watch A Practical Guide to Applying Data Oriented Design (DoD) by Andrew Kelley, the creator of Zig1. Just 10 minutes into the talk, I was confronted with a skill I had never formally learned… the arithmetic behind memory layout of types. Zig is a modern, C-like programming language which…

80386 Multiplication and Division
When Intel released the 80386 in October 1985, it marked a watershed moment for personal computing. The 386 was the first 32-bit x86 processor, increasing the register width from 16 to 32 bits and vastly expanding the address space compared to its predecessors. This wasn't just an incremental upgrade—it was the…

Improving the usability of C libraries in Swift
There are many interesting, useful, and fun C libraries in the software ecosystem. While one could go and rewrite these libraries in Swift, usually there is no need, because Swift provides direct interoperability with C. With a little setup, you can directly use existing C libraries from your Swift code.
