I was poking around in my ~/.cache/ folder using OmniDiskSweeper when I spotted something interesting. The OpenAI Codex desktop app (since rebranded to just ChatGPT) has 1.7GB of stuff in …
From the Zed Blog: Ted Nelson specified the docuverse sixty years ago. The technology finally arrived, and so did its native users.
After 15 years at Google, the creator of JJ joins ERSC as Chief Technology Officer.
The one where I build my own text editor (until I get bored).
Someone opened a PR to implement readahead in Turso. It was a throwaway implementation, but a good excuse to measure io_uring and understand more about it.
The optimizations behind Wasmi 2.0, and how they compare to Wasm3 and Stitch.
Read this Tcl/Tk hands-up/primer to find out how the open-source Command Tool Language toolkit can help you develop cross-plaform tools for Windows, Linux, macOS and even Android.
We are rebuilding Monica from scratch, and this new series will document how.
An Introduction to File Formats and ImHex by Reverse Engineering FEZ's Save File Format
Memoryfields - a vastly simpler way to do agent memory
In 2019 I bet on the no-code revolution. That bet aged so-so. Here is the new one.
Julia, the programming language that originated as a research project at MIT, has gained a loyal following among scientists, engineers, mathematicians, and others. The free and open-source language counts more than 1 million users, including people at thousands of companies and universities around the world.
An introduction to diffusion language models and the research advances that underlie today's diffusion LLMs. We describe the building blocks of recent open-source models, starting from simple masking diffusion, and including techniques for iterative refinement, post-training, and variable-length generation. Material…
I used to wonder why I see so many more bugs than most people. I easily observe hundreds to thousands of bugs per week and nothing seems to work , but most people I talk to don't see anything like this . For a long time, I thought this had something to do with how I use computers but, over time, I've realized that…
I never questioned why code should be highlighted until I tried to make my own theme.
I've spent most of my career working inside the JVM, with a sidebar of Python. So the first time I hit incompatible libc with containerized Bifrost, and GPT suggested musl as the solution, not only did I jump on it, I moved my other Rust projects to musl as
Release announcement, 2026-08-28.
The following presents a fast algorithm for volume computation of a simple, closed, triangulated 3D mesh. This assumption is a consequence of the divergence theorem. Further extensions may generalise to other meshes as well, although that is presently out of scope.
Successful contributions to open source projects are a kind of currency. GitHub in particular encourages this in a number of ways: by showing avatars of contributors on repository pages, by showing your contributions to your followers via the activity feed and by signalling contributions per day on the activity graph…
There is a misunderstanding about software engineering that AI is making increasingly visible: we tend to confuse writing code with building software.

Models are commodifying. The harness - skills, extensions, a scriptable app - is where the work and the leverage now live.
A customer's Go application kept crashing on a 32-bit embedded Linux system. We traced the fatal netpoll error to a pointer aliasing bug in the Go runtime.
Picture this, the year is 1996. You find yourself frustrated with the incumbent search engines like AltaVista, which primarily does a content-based search (it'll give you an article on "Hotels for Chickens" if you search "Hotels" because the word matches). There's gotta be a better way, right? Well, in hindsight, of…
I write code roughly the same way I did ten years ago 1 1 Well, this was true when I started drafting this article. I have since adopted robots to do much more of the actual typing of code, unless it’s a project where (a) I care about code quality, or (b) I try to learn something. : I make edits in my text editor, I…
First, a PSA: Do NOT use Omarchy if you care about security of your machine even a little bit. You can't polish a turd Omarchy 4.0 shipped with a collec...
python has 6 pre-declared "constants": True , False , None , __debug__ , Ellipsis (or equivalently ... ), and NotImplemented . but they all behave slightly differently, for some reason.
Some internet standards only support ASCII characters, but the world uses much more than the Latin alphabet. Thus, a mapping from Unicode to ASCII for use in domain names is required. NamePrep was...
I have too many git branches and like many people I developed a convoluted script to show me the most recent ones. I ran this command many times a day for years:
How do you migrate 2.4 million lines of code?
