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.
Zooko provides a nice example of the problems with most distributed version control systems merge algorithms. He gives an example of a merge situation that most version control systems, including git, get wrong, but that darcs, Codeville, SCCS, and perhaps BitKeeper get correct.
Why I built superlite, an autonomous build workflow for Claude Code that doesn't ask permission every four minutes: how it works, how to use it, and the benchmarks.
This essay explores the connection between Erlang's process supervision, state management and durable execution.
Still not really about LAPACK. It's a second part of the “outperforming” series explaining how the C++ metaprogramming can appear useful for efficient code generation.
A presentation of why, and how, I started using Emacs

I will try to solve all of the advent of code with as little human input as possible
A trampoline is a loop that iteratively invokes thunk -returning functions ( continuation-passing style ). A single trampoline is sufficient to express all control transfers of a program; a program so expressed is trampolined, or in trampolined style; converting a program to trampolined style is trampolining…
Hello everyone. I'm proud to release the result of a Facebook-sponsored study on the feasibility of using the RPython toolchain to produce ...
The git repo as art.
Here's a recipe you can follow when you want to add tests on Legacy Code, but you don't have much ti
I find myself thinking about a particular design principle of Rust today. I’m not sure I’ve ever seen it named specifically before, but it gets referred to from…
From the highly eclectic blog of Mark Dominus
There are a few things you'll need for a productive programming session.
I teased at this a bit in my previous posts and finally have a setup I’m happy with, so I thought I’d do a more in-depth writeup.
Most teams are curious about fine-tuning and how it might help their AI products, but they don't know what to expect from the process, how to measure success, or where to start.
Enable JavaDoc documentation comments to be written in Markdown rather than solely in a mixture of HTML and JavaDoc @ -tags.
Making programs slower can be useful to find...
Interactive C++ for Data Science In our previous blog post “Interactive C++ with Cling” we mentioned that exploratory programming is an effective way to reduce the complexity of the problem. This post will discuss some applications of Cling developed to support data science researchers.
We've already covered the basics of tree data structure in three posts. If you haven't gone through those yet, I would strongly going through the…
Turborepo 1.2 introduces improved task filtering, artifact signing and integrity, human-readable and JSON dry runs, and more!
Although I try to make good use of the debugger, I am quite used to print-based debugging, especially for unit tests. I wanted to explore some tricks to improve print-based debugging, and also incorporate the debugger more.
Discovering a JDK Race Condition, and Debugging it in 30 Minutes with Fray I’ve been adding more integration tests for Fray recently. To ensure Fray can handle different scenarios, I wrote many creative test cases. Many of them passed as expected, while some failures led to epic fixes in Fray. Then something…
A deep dive into the infrastructure of .NET Core. Challenges, changes and the future.
Some thoughts on why git’s complex user interface works so well in practice.
Markdoc delivers a good user experience without compromising the authoring experience. It enables writers to express interactivity and simple page logic without mixing code and content.
I was intrigued by Jev and the self-hostable projects appearing around it, such as OpenJev and SemIf . Reading about them introduced me ...
