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:
However recently it added a killer feature: generated columns . (This was added in 3.31.0, released 2020-01-22.)
An interactive explaination of how QR codes work and techniques for rendering artistic QR codes
Emacs 31.1 adds a slew of quality-of-life features. It retires its quirky unexec dumper; there are general improvements to tree-sitter, including a much-wanted auto-installer for grammars; and much more.
I'm a designer and creative technologist based in Brooklyn, NY.
An agent harness is a piece of software that provides an environment for an AI model to operate within.
Build a copy-and-patch JIT compiler in Rust, generate ARM64 machine code, and benchmark it against an interpreter and handwritten implementation.
People pick languages differently with LLMs.
The macOS command-line tool hdiutil is used to manipulate disk images. From the WHAT'S NEW section of man hdiutil on the latest macOS 27 Golden Gate beta:
This was a very old draft I’ve had sitting around for years. The recent discussions of new query languages like Acadia spurred me to revisit, revise, and publish this. I think one of the biggest causes of NoSQL is that… Continue reading →
The other day, I saw a viral tweet saying that people talking about how LLMs are causing slow, bloated, code are going to eat crow once they re-write everything in super-optimized assembly. We're not quite at the point where we want to write everything in assembly , but some variant of what Nolan Lawson said about…
I built an (almost) fully self-hosted, sandboxed, agentic software factory.

I've always had a fascination with simpler and low power computing. This lead me to run Photoshop on a 60 pence computer chip and it amazes me that this is possible.
std.Io.Threaded is one of the implementations of Zig's new Io interface that enables concurrency. This is a boring just use threads impl. I personally find it neat though --- it does this weird thing that I wanted to do for ages, that to my knowledge no one else is doing properly, and implements it better than I…
It's time to stop drawing user interfaces with punctuation characters. Native UI is a completely solved problem.
TL;DR: I believe Odin's inline assembly is currently the best out of any language.The most important aspects are of this article listed below. I am not aware of any other assembly (GCC/Clang/Rust/Go...) that would combine all of these aspects:Inline assembly is organized into "templates", similar to and callable as…
Solid core + capability-based sandboxes + LLMs = Users with superpowers
You need simplicity if you want to move fast. PostgreSQL can very well replace Kafka, Redis, Clickhouse and Elastic. And many successful companies are doing exactly that. Let's check out how.
I care about Bun. I have been rooting for it since the initial release in 2022. I switched all my development from Node to Bun. I used it in the development of the Nue framework and now with my new project Hertta .
There's been a lot of talk about the vulnpocalypse, to which I don't have much to add because I'm not a security person, but I haven't seen much discussion on the closely related (and to be fair, less serious, issue), the benchmarkpocalypse.
The secret is humble UITextField.
A range of fast modulus techniques that beat compiler output
The manifestation of my imposter syndrome, for me and today, is what does it mean to be a software engineer. There’s a lot more noise than signal on the Internet about agentic engineering, wh…
For many years, I sometimes discovered that commands I was sure I had run were no longer present in my Z shell history file (~/.zsh_history). In this article, I will show you how I tracked down the bug. Spoiler: ultimately, patching Zsh to make it crash loudly and analyzing the crash’s core dump was the winning…
It will ask you hunk by hunk for the things to include in the first commit, and then bring up the editor for the first and second commit message. It couldn’t be simpler than that.
