Understanding the Go Compiler: The Linker
In the previous post , we watched the compiler transform optimized SSA into machine code bytes and package them into object files. Each .o file contains the compiled code for one package—complete with machine instructions, symbol definitions, and relocations marking addresses that need fixing. But your program isn’t…

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.

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…

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.

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…

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.

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…

Provide agents with automated feedback
Back pressure for agents You might notice a pattern in the most successful applications of agents over the last year. Projects that are able to setup structure around the agent itself, to provide it with automated feedback on quality and correctness, have been able to push them to work on longer horizon tasks. This…
