The new "Fractal" operating system kernel, developed at MIT, gives researchers a clearer look at how computer chips work internally. It was used to study the branch predictors inside Apple's M1 processor, where it revealed a potential vulnerability to major speculative attacks.
A presentation of why, and how, I started using Emacs
Gribouille 0.3.0 gives guides and axes a much finer on/off switch, lets compose() carry its own theme, and makes geom-area() stack by default. A long list of legend and annotation fixes rounds it out.
Emacs features have a discoverability problem, and we’re chipping away at it one demo at a time. The years since I wrote the last one of these have yielded more surprising and useful finds, so it’s time again for a “batteries included” report. Note This is the third in a series of articles highlighting useful but…
Eight long held and common beliefs about the network have been shown, time after time, to be false. What are they, and what do they mean?
2. Functions delay binding; data structures induce binding. Moral: Structure data late in the programming process.
I’ve been telling people for the last 25 years that Jane Street as an organization was just not interested in formal methods.
LiveView 1.2 is a small release that adds support for colocating CSS.
I always felt a little bad for the ghosts in Pac-Man. They patrol the maze, they corner the guy, and then he eats a glowing pellet and suddenly they're the ones running for their lives. So I built a small game where you finally get to play the other side.

Once upon a time, a frontend ticket landed on my queue which was not properly mine, but the only other Arabic reader on the team was on leave. It went roughly as follows; a block of mixed-content Arabic prose on the …
How imprecise UI animations erode trust in product
TrueType is a widely used vector font standard for rendering text in web pages, PDFs, operating systems, and applications. Familiar fonts like Helvetica, Garamond, and Monaco are all built on TrueType outlines. The format specifies a hinting interpreter intended to help outlines rasterize faithfully on low-resolution…

WASI 0.3 is official, and async is now native to WebAssembly Components. The WASI Subgroup voted to ratify WASI 0.3.0, rebasing WASI onto the WebAssembly Component Model’s async primitives. The 0.3.0 specification is now stable, and runt...
A tour of erm, a local CLI that removes disfluencies from English speech recordings using faster-whisper, a few detectors that look at the audio directly, and ffmpeg.

Large DELETEs add work instead of reclaiming it. Structure your database so deletion becomes DROP TABLE or TRUNCATE.
From the Zed Blog: Agents turned the conversation into the real source of our software. DeltaDB is the version control built for it.
We benchmarked Claude Fable 5 on 200 real-world coding tasks for the Agent Security League.
Once I wrote users.select { |u| u.admin? }.map(&:email) and realized I’d written Lisp.
Meet North Mini Code, Cohere's first open-source agentic coding model: a 30B MoE that codes strongly on minimal hardware.
A case against measuring AI-assisted engineering by code volume and other vanity metrics instead of outcomes.
In this blog post, I will share the adventures I had creating my own LLM, from (almost) scratch, trained only on old texts. I made my own base-training and fine-tuning scripts, data processing pipelines and custom datasets. ("almost from scratch" means I did use existing programming languages and libraries, I didn't…
An overview of DiffusionGemma, an exceptionally fast text generation model with up to 4x faster speeds.
Last year I've fixed a bug in Linux kernel OHCI (USB 1.1) stack , which rendered my old printer unreliable: OHCI adds artificial delay of 1ms for each USB transfer of send-read pattern, while my very old, host-based printer expects very tight timings and constant latency, like some kind of CnC machine.
Thank you for the support, this blog post got featured on the front page of Hacker News (YCombinator).
Our next npm major version, v12, introduces security-related default changes to npm install. All these changes are available behind warnings in npm today on 11.16.0 or newer, so you can…
We used agents to port all of Git to library-first, memory-safe Rust and it passes the entire C Git test suite.
