A look under our trunk: what's in our compute
Compute is the brain of the Waymo Driver, translating raw sensor data into real-time driving commands. Operating demonstrably safe, physical AI on the road demands a fundamental shift towards a system engineered for deterministic, low-latency performance. Over the past decade, we have co-designed our hardware…

A third world engineer responds to “RISC-V: They should have known better”
Dmitry Grinberg published a long piece explaining his distaste for RISC-V, you can read his article here: RISC-V: They Should Have Known Better - Dmitry.GR . It went to the front page of Hacker News and it started a good argument on Lobsters. It is the most substantial criticism the architecture has had in a while and…

A True Telnet BBS on a Casio Calculator
About a eight weeks ago I had virtually no interest in calculators. Blank, dull, tedious-looking objects that remind me of long, arduous rainy afternoons in 1980’s/1990’s school maths classes.

Making holograms with a pen plotter
I have a pen-plotter! It’s great. It’s like having a printer but slow and it breaks more often. I got it on eBay and it came sorta broken and I immediately spent the difference between what I paid and the price of new one fixing it. Now it’s fixed!

Triton: DirectX 11 Driver for QEMU
In the prequel, we introduced Neptune, a Direct3D protocol forwarding layer for VirtIO. Neptune allowed us to serialize Direct3D API calls across the hypervisor boundary and this allowed us to run Wine games on a Linux guest with a Linux host faster than with DXVK directly in the guest. Admittedly, the payoff there…

Can you reverse engineer an ASIC?
Earlier this year we published a puzzle that handed you a complete neural network and asked you to figure out what it did. The response was great, so we’ve made another one! This time, we’re going much deeper down the tech stack.

The simple elegance of the integrated timing belt loopback fastener
I’ve recently been working on a mechatronics project that involves constructing an X-Y cartesian motion system. I opted to use stepper motors to drive each axis, and timing belts and pulleys for translating the rotational torque of the steppers into linear motion. The timing belts need to be anchored to the component…
