What even is an OS now?

Computers now work the way I thought they did when I was 8. What does computing look like when most applications have an audience of 1-2 people? I’m leaving Fly.io to build a phone for that world.

Plan mode is dead

Earlier this year, I believed planning was going to become the most important part of building software with AI.

Running a Jev-Style Decision Model on One TPU v6e: What Fits, What It Costs, and What Changes From a GPU

Gemma 4 E2B, E4B, 12B and a 26B-A4B fp8 build read by their label probabilities with vLLM on one TPU v6e chip, checked against the same read on an NVIDIA L4 and against Jev 1.13.0's published results. What fits one chip, how to read labels when vLLM on TPU returns only the top 32 log-probabilities, speed, cost, and why no 31B loads today.

Two and a half years without a gallbladder

Two and a half-ish years ago (late February 2024) I had emergency surgery to remove my gallbladder. I had been meeting with a nutritionist about my digestive issues for a couple years (after trying to figure diet improvements out myself), and working my way through tests and specialists trying to hunt down the source of my issues: H. Pylori test, low FODMAP+ elimination diet, trying to regulate my cortisol levels better, taking a proton pump inhibitor, probably more I don’t remember… Turns out, I just had atypical symptoms and/or described them poorly, which made me skeptical* when I finally got the diagnosis.

Fourier Analysis: Drawing Llamas with Circles

The Fourier transform is a method of transforming an input signal from the time domain to the frequency domain. It has a huge range of applications, for instance audio engineers can pick out individual undesired frequencies in a song with the Fourier transform and then get back the sound without that frequency using the inverse Fourier transform. We can make use of the Fourier transform in digital image processing for filtering images, like gaussian blurs and compressing images using the JPEG format. Lastly, as this article will go into: drawing!

Plain Gemma 4 26B vs Jev on One EC2 L4: 2.1 Points Behind Overall, Level on Yes/No, 4.5 Behind on Multiple Choice

Plain Gemma 4 26B read by its label probabilities against DiffusionGemma's one-step read, both as community 4-bit (AWQ) builds on one EC2 L4, on 1,200 labelled examples and on the 3,880-record public suite where Jev 1.13.0 has published results. Pre-registered, with accuracy, calibration, calibration after 0 to 150 labels, latency and cost.
