Pair Your Compilers at the ABI Café
Not sure if your compilers have matching ABIs? Then put them through the ultimate compatibility crucible and pair them up on a shift at The ABI Café! Find out if your one true pairing fastcalls for each other or are just another slowburn disaster. (Maid outfits optional but recommended.)

Decoding UTF8 with parallel extract
As a side-quest I recently decided to write a branchless utf8 decoder utilizing the pext or "parallel extract" instruction. It's compliant with rfc-3629 , meaning that it doesn't just naively decode the code-point but also checks for overlong encoding, surrogate pairs and such. Compiled with gcc -O3 -march=x86-64-v3…

A 100x speedup with unsafe Python
We're going to speed up some numpy code by 100x using "unsafe Python." Which is not quite the same as unsafe Rust, but it's a bit similar, and I'm not sure what else to call it... you'll see. It's not something you'd use in most Python code, but it's handy on occasion, and I think it shows "the nature of Python” from…

Swift's native Clocks are inefficient
In absolute terms they don’t have much overhead – think sub-microsecond for most uses. Which makes them perfectly acceptable when they’re used sporadically (e.g. only a few times per second).

Using a LLM to compress text
Introduction Large language models are trained on huge datasets of text to learn the relationships and contexts of words within larger documents. These relationships are what allows the model to generate text. Recently I've read concerns about LLMs being trained on copyrighted text and reproducing it. This got me…

Rewriting the Technical Interview (2020)
Update, November 2023: here are the full term rewrite and language macros which formed the seed of this story. These files include OO notation as well as the basic Algol syntax shown here. There is also a sketch of an object-oriented language with classes and inheritance, implemented as a Clojure macro. I do not…

LLMs can't do probability
I've seen a couple of recent posts where the writer mentioned asking LLMs to do something with a certain probability or a certain percentage of the time. There is a particular example that stuck in my mind which I've since lost the link to (If you're the author, please get in touch so I can link through to you): The…

Flow Field Pathfinding
You may know me for my interactive tutorials. But before that, I was writing visual but non-interactive tutorials. In particular, there wasn’t a lot of information about A* on the web, so I decided to collect all my notes about pathfinding [1] together in one place in the 1990s. But then in the 2010s I started making…

How to improve the RISC-V specification
My main project is to create an executable spec of the Intel Architecture but, every now and then, I get to take a broader look at ISA specifications and think about the strengths and weaknesses of other ISA specs: what makes them work well; and what techniques they could borrow from other specifications. Earlier this…
