The Coming Loop

written on June 23, 2026 I don’t prompt Claude anymore. I have loops running that prompt Claude and figuring out what to do. My job is to write loops. — Boris Cherny Over the last months I have watched more and more people build something on top of coding agents that feels meaningfully different from […]
Crypto in 2026: Oh, This Is the Bad Place

May 25, 2026 Reading Mode Wider Open your favourite Doom News App any morning in 2026 over your morning coffee, and the only honest phrase that should come out of your mouth is, ”Oh, this is the Bad Place.” Because the world has gone truly mad. The president of the United States is running a […]
Run isolated sandboxes with full lifecycle control: AWS introduces MicroVMs

Today, we are announcing AWS Lambda MicroVMs, a new serverless compute primitive within AWS Lambda that lets you run code generated by users or AI in isolated, stateful execution environments. You get virtual machine level isolation, near-instant launch and resume, and direct control over environment lifecycle and state, all without managing infrastructure or building expertise […]
I built a GPU back end for Emacs

A few months ago I became obsessed with a silly question: why does my Emacs, on a laptop with a perfectly capable GPU, draw all of its text using the CPU? And that led to others: why can’t I play a video inside a buffer? Why can’t I have animated cursor effects? Why can’t I […]
A game where you’re an OS and have to manage processes, memory and I/O events

This is a game where you are the operating system of a computer. As such, you have to manage processes, memory and I/O events. Make sure not to leave processes idling for too long, or the user will get really impatient and reboot you! You can play the game here: https://plbrault.github.io/youre-the-os Also available on itch.io. […]
AI Built a Nuke and Still Lost

I gave an AI a civilisation to run. By the midgame it was winning: a trade network that dominated the map, alliances on every border, a diplomatic victory within reach. It had outbuilt, outearned, and outmanoeuvred every rival on the board. What it hadn’t noticed was France. Quietly, across a hundred turns, French culture had […]
The new HTTP QUERY method explained

In the world of RESTful APIs, we have long lived by a strict set of (self-imposed) rules. Whether you are fetching data with GET, creating an entity with POST, or updating a resource with PUT, the HTTP method tells the server what your intention is. Quite recently, RFC 10008 got published, which defines the new […]
Will It Mythos?

OK, so Mythos finds really challenging security bugs, right? That’s why it’s cordoned off from the hoi polloi, to protect the world from such a powerful finder of exploits. I am skeptical of the reasons given publicly, I suspect it’s really just so much more expensive to operate than their current models that they don’t […]
GLM-5.2 is a step change for open agents

Housekeeping: Following my “State of the blog” post last week, noting a slight increase in paid features, it’s a good time to remind folks that I offer group subscriptions with larger discounts proportional to the number of seats. I also released a new paper today on open RL recipes for terminal agents, read more here. […]
Ultralytics YOLO26: Unified Real-Time End-to-End Vision Models

Abstract:Real-time vision demands models that are accurate, efficient, and simple to deploy across diverse hardware. The YOLO family has become widely deployed for this reason, yet most YOLO detectors still rely on non-maximum suppression at inference, carry heavy detection heads due to Distribution Focal Loss, require long training schedules, and can leave the smallest objects […]
