[Cory House @housecor]

I spent 25 years getting good at web dev.

I memorized syntax, browser APIs, accessibility techniques, and performance optimizations, security patterns, and learned dozens of libraries and frameworks.

Now I'm trying to decide what knowledge still has value.

[Ayaan 🐧 @twtayaan]

One developer reverse-engineered Apple's GPU from scratch.

5 years later, Linux runs on it with full graphics acceleration. 🐧⚡️

Meet Alyssa Rosenzweig 🇨🇦

> Canadian software developer.
> Started reverse-engineering GPUs in high school, 2017.

> Stayed for five years instead.
> Apple's M1 GPU had zero public documentation.
> Zero drivers. Zero help.
> She bought a Mac Mini and started decoding it from scratch.
> Drew her first working triangle within weeks.
> Once you can draw a triangle, you can do anything.
> Shader compiler. Command streams. Full rendering pipeline.
> Built complete Mesa drivers.
> OpenGL 4.6. OpenGL ES 3.2. Vulkan 1.4. OpenCL 3.0.
> All open source. All fully upstream.
> Her work is why Proton and 3D gaming run on Linux on M1 and M2 Macs.
> Did most of this as a CS student at the University of Toronto.
> Coursework. A part-time job. Reverse-engineering Apple Silicon. All at once.
> Finished in August 2025.
> Then moved on to Intel.

Apple never opened the door.
