C++26 brings us a small but meaningful cleanup to the language: deprecating ellipsis parameters without a preceding comma. This change, proposed in P3176R1, aims to improve C compatibility, reduce confusion, and pave the way for future language features. The proposal’s name is a playful reference to the Oxford comma …
This post is an expanded version of a presentation I gave at the recent WebAssembly CG meeting in Munich. WebAssembly has come a long way since its first release in 2017. The 1.0 version of WebAssembly was already a great fit for low-level languages like C and C++, and immediately enabled many new kinds of…
A programmer's text editor is their castle

Python loses every public benchmark by 21-875x. I took the exact problems people use to dunk on Python and climbed every rung of the optimization ladder -- from CPython version upgrades to Rust. Real numbers, real code, real effort costs.
Over the course of four weeks in January and February, I built a new programming language using Claude Code. I named it Cutlet after my cat. It’s completely legal to do that. You can find the source code on GitHub , along with build instructions and example programs .
Turing Award winner and former Oxford professor Tony Hoare passed away last Thursday at the age of 92. Hoare is famous for quicksort, ALGO...
I read Ian Whitlock’s article on why he can’t quit Magit and it inspired me to share more about Magit from my perspective. This article will focus on rebasing.
AI's coding ability is outpacing our ability to wield it effectively. That gap closes in levels — 8 of them. Here's the progression from tab complete to autonomous agent teams.

I touched "every" OS so you don't have to
Literate programming is the idea that code should be intermingled with prose such that an uninformed reader could read a code base as a narrative, and come away with an understanding of how it works and what it does. Although I have long been intrigued by this idea, and have found uses for it in a couple1 of different…
I built a tiny programming language where programs are candy grids, complete with a renderer, photo decoder, AST tree, and execution trace.
AI coding is blurring the lines between engineers, PMs, and designers. In the short-term, it's going to cause havoc. What happens long-term?
It’s looking like I’m going to need to build a reactive engine for work, so I’m going to prepare for that by writing down what I know about them. I want to look at three ways of building reactive engines: push reactivity, pull reactivity, and the hybrid push/pull combination that is used in a bunch of web frameworks…
I’ve forgotten how to write code, or at least I think I have. Hard to be sure, I haven’t done it for a while. But then, I start to muse…
In early December 2023, I wrote a drawing program called WigglyPaint and published it on Itch.io.
One of the simplest tests you can run on a database:
If you're using Dapper with anonymous objects to query varchar columns, you're probably sending nvarchar(4000) parameters — causing CONVERT_IMPLICIT on every row and defeating your indexes. Here's the fix.
Today we are excited to announce the Release Candidate (RC) of TypeScript 6.0! To get started using the RC, you can get it through npm with the following
I’m sometimes late to notice new and terrible things about macOS 26 Tahoe, because I use it only for testing, on a secondary Mac. My main Mac remains on Sequoia, as enforced by Little Snitch . I was of course aware that app windows on Tahoe have exaggerated corner radiuses, but I was unaware until now that the window…

Good software knows what problem it solves and what needs to be tackled by another tool
The four-pane System Browser has shaped Smalltalk development for forty years. It’s still brilliant at providing context. But the real problem may not be the browser itself—it may be the lack of composition between the tools that surround it.
