America could have $4 lunch bowls like Japan but for zoning laws
Zoning and food safety laws add up to outlaw tiny restaurants operated by one or two staff.
Starlink militarization and its impact on global strategic stability (2023)
In this piece, two researchers from PLA-affiliated National University of Defense Technology argue that Starlink will negatively impact global stability, in light of its clear military applications, increased risks of accidents and collisions in space, and SpaceX's close relationship with the U.S. military. The…

Debunking an alarmingly common HTML misconception.
Rust is just a tool
A programming language should not be your identity.
America's Cyber Defense Agency Is Burning Down and Nobody's Coming to Put It Out
CISA lost a third of its staff and its acting leader uploaded sensitive docs to public ChatGPT, while China sits inside U.S. critical infrastructure.

The Rise of the Bullshittery
A few thoughts on how the modern economy has stopped rewarding people who know what they are doing, and started rewarding people who know how to look like they do.
It wasn't AI that flipped Proton's charge
Proton's CEO called a request for security testing "loser thinking". Using AI to write code is fine, but for a privacy company, the guardrails around that code are the product.
Creativity is the new moat
AI makes it fast and easy to copy what’s already out there—but your competitive edge could learn a little something from web history
Many hells of WebDAV
Standards are great, until they aren't
An ode to bzip
The story goes like this. ComputerCraft is a mod that adds programming to Minecraft. You write Lua code that gets executed by a bespoke interpreter with access to world APIs, and now you’re writing code instead of having fun. Computers have limited disk space, and my /nix folder is growing out of control, so I need to…
The development pipeline is a production system
Various thoughts on programming and technology.
RTK reports token savings, but our cost benchmarks disagree
We tested RTK (Rust Token Killer) with Claude Code on Fable 5.0, and OpenCode with DeepSeek V4 Pro 0813 on Terminal-Bench 2.1.
Adaptive PDFs
An idea for PDFs that render normally for humans while exposing clean markdown structure to extractors and LLMs in the same file.
A shell exclamation mark is not for yelling. Be lazy
Event designators have been hiding in not-so-plain-sight since the late 1970s — so powerful that forgetting might be part of a massive conspiracy to wear out developer keyboards faster than otherwise.
Allocating on the Stack
A description of some of the recent changes to do allocations on the stack instead of the heap.
Servo 2025 Stats
Some numbers about the evolution of the Servo project and its community during the last years.
What else do people draw on gradient.horse?
Since gradient.horse went online in January 2026, six months have passed, and more than 600 000 horses (and non-horses) were drawn. There are now more horses on gradient.horse than in the wild. The image model I trained to filter out vandalism works very well, but it also hides a lot of ingenious drawings. You could…
Electric motor scaling laws and inertia in robot actuators
Engineering contraptions
Signals, the push-pull based algorithm
We have been using Signals in production for years via several modern front-end frameworks like Solid, Vue, and others, but few of us are able to explain how they work internally. I wanted to dig into it, especially diving deep into the push-pull based algorithm, the core mechanism behind their reactivity.

The Physics of GPS
An interactive exploration of how GPS works: from the speed of light and trilateration to the cheap clock problem and Einstein's relativity corrections.
Policy on the AI Exponential
In one of the side plots to The Lord of the Rings , two of the Hobbits attempt to rouse Treebeard—a wise but ponderous sentient tree—to defend his forest from an army that is cutting it down. The problem is that Treebeard operates at a very different speed than the Hobbits. It takes him a full day simply to say hello…
Please do not A/B test my workflow
Anthropic is silently A/B testing Claude Code's plan mode on paying users. This isn't a consumer app. Stop treating it like one.
Fraud investigation is believing your lying eyes
The financial industry has paid tens of billions of dollars in tuition on fraud detection. Here are some observations for investigators with badges, press cards, or GoPros.
