The quiet resurgence of RF engineering

As a retro-computer enthusiast, it seems that parts are either insanely expensive or dirt cheap. If the first case has obvious problems, the second can also lead to issues.
For years, the best way to get 10 gigabit networking on laptops was to buy an expensive, large, and hot 10 GbE Thunderbolt adapter. With new RTL8159-based 10G USB 3.2 adapters coming onto the market, the bulky adapters might be a thing of the past. Just look at the size of the thing in comparison to my Thunderbolt…
I bought a Rodecaster Duo to solve some audio woes, and found that it has ssh enabled by default. I captured the firmware update process and created custom firmware to enable password authentication for ssh.
How does Intel's new Arc Pro B70 32GB professional GPU stack up against the competition in media editing, rendering, AI, CAD, and BIM applications?
Porting a 2012 OpenCV paper to YOLOv8 and CoreML on iOS to score rifle shooting targets from a photo - replacing the brass-plug scoring gauge with on-device computer vision.
iPads should be radically touch only, and MacBooks should be keyboard-first
An overview of Google’s eighth generation TPUs, built for the agentic era.
An interactive exploration of how GPS works: from the speed of light and trilateration to the cheap clock problem and Einstein's relativity corrections.
Before GPS, how did aircraft navigate? One important technique was celestial navigation: navigating from the positions of the stars, planets...
Today, we’re announcing Ternary Bonsai, a new family of 1.58-bit language models designed to balance strict memory constraints with high accuracy requirements.
We gave Codex a foothold. It popped a root shell.
Gemma 2B scored ~8.0 on MT-Bench. GPT-3.5 Turbo scored 7.94. An 87-times-smaller model on a laptop CPU, no GPU anywhere in the stack. We published the full tape — every question, every turn, every score — so anyone can verify it. We found seven failure classes. Not hallucinations. Specific patterns: arithmetic where…
36 mechanical keyboards. Click. Type. Listen. From IBM Model M (1985) to modern thocky customs.
Gemini Robotics ER 1.6 upgrades spatial reasoning and multi-view understanding, unlocking new capabilities like instrument reading for autonomous robots.
The FPGA 386 core I've been building now boots DOS, runs applications like Norton Commander, and plays games like Doom. On DE10-Nano it currently runs at 75 MHz. With the core now far enough along to run real software, this seems like a good point to step back and look at one of the 80386's performance-critical…
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…

If you often get static electricity shocks when touching your laptop or your office chair, or your monitor goes black when you stand up, this may interest you.
This was a long one–I spent a fair bit of time with the Orange Pi 6 Plus over the past few months, and what I expected to be a quick look at another fast ...
The killer app for the 486 didn't come out until a year or so later
Researchers at ETH Zurich have realised particularly stable quantum logical operations with qubits made of neutral atoms. Since these operations, called quantum gates, are based on geometric phases they are extremely robust against experimental noise and can be used in quantum computers in the future.
Passive radar is radar that doesn't need a transmitter; it uses existing broadcasts of opportunity.
In this blog I will look at some of the drivers for the growth of RISC-V, its value proposition and explain why supporting RISC-V is important to Canonical. […]
Pedestrians wearing headphones are exposed to an increased risk of accidents. In an effort to reduce collisions with cyclists, Škoda Auto, in collaboration with scientists, introduces an innovative bicycle bell whose sound can penetrate even active noise cancellation systems. In doing so, it helps prevent injuries to…
How to move fast when building for the physical world
I spent years building one of the most popular LED strip visualizers on GitHub. It's the kind of project that's easy to get started but diabolically hard to master.
Any Boolean function can be computed with Tofolli gates, and Tofolli gates are reversible, and so any Boolean function can be computed reversibly.
49 graphics cards. 30 years. From Quake to Cyberpunk.
As the eleventh hour dawns all the pieces start to fall into place. I lived my life knowing this would happen, yet when it is I may be just as unprepared as anyone else. As any self driving car maker knows, predicting doesn’t mean you can act.
