California’s bill, AB 2047, will not only mandate censorware on all 3D printers; it will also criminalize the use of open-source alternatives. Repeating the mistakes of DRM won’t make anyone safer, but it will hurt innovation in the state and risks a slew of new consumer harms ranging from surveillance to platform…
ML, Biotech, Hardware, and Coordination Problems. Sometimes I write about hard problems and how to solve them.
NVIDIA’s latest AI servers can run on coolant warmer than a hot tub — and that counterintuitive choice is one of the biggest efficiency leaps in data center history.
BYD sold 4.6M vehicles in 2025, but Americans can't buy one. We CT scanned four components from its lineup to reveal what vertical integration looks like at the part level.
Introducing Robostral Navigate: 8B model achieving 76.6% on R2R-CE with just a single RGB camera. No depth sensors, LiDAR, or multiple cameras needed.
People still tell me that CPUs are boring. That nothing much happens anymore. Let us look at AMD Ryzen 7 processors from 2022 to 2024: the 5800X3D (Zen 3), the 7800X3D (Zen 4) and the 9800X3D (Zen 5). They are comparable 8-core chips with 3D V-Cache. I have written about them before, in How stagnant … Continue reading…
Disclaimer: None of this is written by AI, I’m still a real person writing my own blog like its 1999 I finally figured out how to do Gigabit Ethernet over my existing phone wires. Powerline adapter…
I’m starting a new build-in-public project: oomwoo, an open-source robot vacuum you build yourself. Raspberry Pi, ROS 2, 2D LiDAR, Home Assistant, 3D printed, local-first — and open from the first commit.
The Leica G9ii
Today we're releasing Bonsai Image 4B, compact 1-bit and ternary diffusion models built on FLUX.2 Klein 4B that run image generation on laptops and phones.
If you're giving me e-paper, I'm going to make an e-printer.
An overview of Google’s eighth generation TPUs, built for the agentic era.
an adventure in image processing and taking very wide photographs (blog post; 4,600 words)
I reverse engineered the hardware and firmware of my Egret GT E-Scooter. I describe how I got in, analysed communication between components, and reverse engineered firmware. I speak about writing custom firmware for the display unit.
High-bandwidth memory (HBM) accounts for 63% of AI chip component costs, up from 52% in Q1 2024. Epoch AI's breakdown of component cost shifts across major chip designers.
Apple today announced the new 14-inch MacBook Pro with M6, delivering more performance, powerful on-device AI capabilities, and faster connectivity.
Apple announced the new iPad Air featuring M4 and more memory, giving users a big jump in performance and making it more versatile than ever.
My old 2016 MacBook Pro has been collecting dust in a cabinet for some time now. The laptop suffers from a “flexgate” problem, and I don’t have any practical use for it. For quite some time, I’ve been thinking about repurposing it as a guinea pig, to play with FreeBSD — an OS that I’d aspired to play with for a long…
Porting Linux to Apple Silicon
Before GPS, how did aircraft navigate? One important technique was celestial navigation: navigating from the positions of the stars, planets...
A startup called Taalas , recently released an ASIC chip running Llama 3.1 8B (3/6 bit quant) at an inference rate of 17,000 tokens per seconds. That's like writing around 30 A4 sized pages in one second. They claim it's 10x cheaper in ownership cost than GPU based inference systems and is 10x less electricity hog…
My experience fixing my Framework 13” laptop with AMD 7060 series that was bricked due to a failed BIOS update with US$20 worth of tools, instead of replacing the motherboard as suggested by Framework support.
Apple today announced the new MacBook Air with M5, bringing exceptional performance and expanded AI capabilities to the world’s most popular laptop.
Arm introduces the Arm AGI CPU to power agentic AI infrastructure with rack-scale performance, efficiency and scalable compute for next-generation data centers.

A look at what current models can build, where they fail, and how EEBench tests the electronics in simulation.
Building a custom octocopter from scratch with an RL controller that sustains flight through motor failures. Follow the build log.
Almost a decade ago, I released a hackintosh guide on running macOS 10.14 through a VM with an x86 host. A "Hackintosh" is the feat of running macOS on non-Apple hardware, and has a history dating back to the late 1980s. At the time KVM and PCI
