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).

A High-Level Technical Overview of Homomorphic Encryption
About two years ago, I switched teams at Google to focus on fully homomorphic encryption (abbreviated FHE, or sometimes HE). Since then I’ve got to work on a lot of interesting projects, learning along the way about post-quantum cryptography, compiler design, and the ins and outs of fully homomorphic encryption. If…

Time-Based CSS Animations
In my earlier post Time Uniform For CSS Animation, I took a note about a way to do CSS animations with time ticks instead of keyframes. It was limited applicable because CSS lacked the ability of doing complex Math calculations. After years of wait, CSS now has enough Math functions supported, particularly mod()…

A love letter to bicycle maintenance and repair
It was the 28th of June, 2020; the perfect summer day. I remember it distinctly because of two important events that took place on that day.
