Cosmopolitan v3.9.2
Cosmopolitan's Windows support may finally be feature complete. It's now possible to send signals between processes using kill() on Windows. Ten new torture test programs have been written to tease out more fixes and offer a high level of assurance that signal handling is correct. Some of these tests are good enough to deadlock the signal handling of UNIX OSes but not our ...
Rust for Linux revisited
Ugh. Drew’s blogging about Rust again.
– You
I promise to be nice.
Two years ago, seeing the Rust-for-Linux project starting to get the ball rolling, I wrote “Does Rust belong in the Linux kernel?”, penning a conclusion consistent with Betteridge’s law of headlines. Two years on we have a lot of experience to draw on to see how Rust-for-Linux is actually playing out, and I’d like to renew my thoughts with some hindsight – and more compassion. If you’re one of the Rust-for-Linux participants burned out or burning out on this project, I want to help. Burnout sucks – I’ve been there.
The people working on Rust-for-Linux are incredibly...
AI Training Shouldn't Erase Authorship
In a world of infinite automation and infinite surveillance, survival is going to depend on being the least boring person. Over my career I've written and attached my name to thousands of public source code files. I know they are being scraped from the web and used to train AIs. But if I ask something like Claude, "what sort of code has Justine Tunney wrote?"...

So you want to compete with or replace open source
We are living through an interesting moment in source-available software.1 The open source movement has always had, and continues to have, a solid grounding in grassroots programmers building tools for themselves and forming communities around them. Some looming giants brought on large sums of money – Linux, Mozilla, Apache, and so on – and other giants made do without, like GNU, but for the most part if anyone thought about open source 15 years ago they were mostly thinking about grassroots communities who built software together for fun. With the rise of GitHub and in particular the explosion of web development as an open platform, commercial stakeholders in...
text coordinate systems
Interesting discussion of some of the subtleties which come up when writing code to display and manipulate text:
https://zed.dev/blog/zed-decoded-text-co...te-systems
Much of this echoes Finseth's classic book on implementing emacs-style editors, but with updates to reflect our Unicoded world.
(Many people will avoid dealing with these issues by simply dropping in whatever text widget their favorite library provides, but I enjoy cooking from scratch.)
