A refreshingly simple data-driven game engine built in Rust

Hello! 👋

⚠️ Recruiters I'm very happily employed and not looking for a job, sorry.

I'm Alec, I live in San Diego. I'm an adrenaline junkie software engineer.

• Coding 🖥️
• Flying airplanes and aerobatics 🛩️
• Rock climbing 🧗‍♂️
• Skiing ⛷️
• My adorable dog Ada (yes, named after Ada Lovelace) 🐶

I've been all over the software stack, working on ChromeOS (low level firmware, and high level CI systems) at Google, games at Sunblink, and web stacks all over the place. I have a passion for GPUs, hardware and bare-metal software, and cutting edge web tech (WASM, WebRTC and WebGPU).

In 2020 I founded Tungsten Labs with my tech lead back from Google, we created Maglev, a peer-to-peer RPC framework built on WebRTC. I'm still very passionate about that project, but it's on hold for now.

Projects

My favorite personal project is https://github.com/AThilenius/logic-paint-rs It is:

• Based on a game by Zachtronics called KOHCTPYKTOP, which sadly isn't playable any more because it's a flash game
• Written in Rust (because I'm obsessed with Rust)
• Compiled to WASM
• Uses WebGL2 for fixed-cost (by pixels) hardware accelerated rendering
  • Each 'cell' is a single 16 bit unsigned texel and rendered entirely in a fragment shader.
• Lets you edit and simulate transistors (something between BJT and CMOS, for you hardware people)

Once I finished with the editor I then built a functional 16 bit CPU in it, modeled after the CL-3B ISA. It's micro-coded with a common 16-bit bus, 8 registers with dual output and a 16K of RAM (not drawn here).

I love this project dearly, because it requires knowledge of how a computer works all the way from the transistor up to WASM running in Chromium (which is what VSCode is build with). Next up is a toy language with a homemade compiler for it 😊 Have to rewrite my parser-generator first though!
