You found it. 🍌
The banana at the Next Gen Roadster reveal wasn't an accident. It was an analog stopwatch.
A laser triggered the drop the instant the tires started to roll. We hung it at exactly the car's 0-60 time at the time of 1 second.
Banana hits the ground. Car hits the laser wall. Same frame.
Here's how we did it 🧵

There are now 200,000 Teslas registered in Norway
That's around 20% of EVs in the country

Depth-aware light injection in TypeGPU
I got a 448x448 monocular depth model down to ~8 ms on my M4 Pro across ~250 dispatches, which is fast enough to use in realtime :D
Since the inference is written directly in TypeGPU, I can just feed the depth buffer straight into the lighting pass. It never has to leave the GPU or go through any extra synchronization/interop step
Inference, lighting and draw all go through the same command encoder.

Andrej Karpathy:
"Prompting is going away.
Delete everything, keep Graph."
In 1 hour he shows how to build Graphs, and why it's the only thing that will be left standing at the end.
The missing piece most people don't get: LLMs, prompts, agents, they're all steps. Graph is where you end up.
Watch it, then read the full guide on Graphs below.

The video is Andrej Karpathy's Stanford CS25 lecture from 2023 explaining Transformer neural network architecture and attention mechanics. It does not discuss agent 'graphs' or prompting going away, and there is no record of Karpathy making the attributed quote. youtube.com/watch?v=XfpMkf…

This is the true shape of our planet, known as GEOID.
Readers added context they thought people might want to know
The geoid is a mathematical equipotential surface approximating mean sea level under gravity, not the physical shape of Earth's surface. en.wikipedia.org/wiki/Geoid oceanservice.noaa.gov/education/tuto…
