Why we don’t use AI
We get asked about AI a lot. Whether we’re going to add it to Yarn Spinner, whether we use it ourselves, what we think about it. Fair questions. Time to write it all down. Yarn Spinner doesn’t use the technology that’s currently being called AI. We don’t have generative AI features in the product, and we don’t use…

Date is out, Temporal is in
Temporal is the Date system we always wanted in JavaScript. It's extremely close to being available so Mat Marquis thought it would be a good idea to explain exactly what is better about this new JavaScript date system.

LLVM: The bad parts
A few years ago, I wrote a blog post on design issues in LLVM IR . Since then, one of these issues has been fixed fully (opaque pointers migration), one has been mostly fixed (constant expression removal), and one is well on the way towards being fixed (ptradd migration).

Reproducing DeepSeek's MHC: When Residual Connections Explode
DeepSeek replaced standard residuals with massive Hyper-Connections, and then watched them explode. I reproduced the 9x signal amplification to understand their fix: the Sinkhorn-Knopp algorithm. Part 1 of 2.

HTML-only conditional lazy loading (via preload and media)
The accepted practice is to not add lazy-loading to images above the fold, especially the LCP image, since doing so can delay their loading until the browser has determined they are definitely in the viewport. One problem though is that "above the fold" depends on screen size: an image can be above the fold on desktop…

Finding and fixing Ghostty's largest memory leak
A few months ago, users started reporting that Ghostty was consuming absurd amounts of memory, with one user reporting 37 GB after 10 days of uptime. Today, I'm happy to say the fix has been found and merged . This post is an overview of what caused the leak, a look at some of Ghostty's internals, and some brief…

Generate QR Codes with Pure SQL in PostgreSQL
As my cat woke me up way too early for a Saturday morning, I decided to put all this extra time (and my ChatGPT Pro subscription) into good use and generated a QR-code generator for PostgreSQL, written as a single pure SQL statement. No external libraries or Postgres extension installation needed! The pqr.sql example…
