My Top 100 Programming, Computer and Science Books: Part One
I was recently interviewed by Fog Creek and one of the questions was about my favorite programming, coding and development books. I got very excited by this question as I'm a huge book nerd. I love books about computers, programming, and science. Every few months I spend a day or two researching the latest…

Baba Is Eval
Baba is You is a sokoban puzzle game where the rules themselves have to be manipulated to win. (For the uninitiated, the store page should explain the idea best.) The level of abstraction required to solve most levels makes it a formidable reasoning benchmark, with many reasoning steps being completely orthogonal to…

The Transformer Family
Many new Transformer architecture improvements have been proposed since my last post on “The Transformer Family” about three years ago. Here I did a big refactoring and enrichment of that 2020 post — restructure the hierarchy of sections and improve many sections with more recent papers. Version 2.0 is a superset of…

Hash-based bisect debugging in compilers and runtimes
Does this sound familar? You make a change to a library to optimize its performance or clean up technical debt or fix a bug, only to get a bug report: some very large, incomprehensibly opaque test is now failing. Or you add a new compiler optimization with a similar result. Now you have a major debugging job in an…

Lossy CSS compression for fun and loss (or profit)
Late last year, I had an idea that’s been steadily brewing in my head. I’ve found myself with some free time recently (it coincided with vacation, go figure), and I’ve hacked together some proof-of-concept code. Whether or not it is actually proving the concept I’m not sure, but the results are somewhat interesting…

Who is vfmaddrnd231pd?
vfmaddrnd231pd is a unique instruction from the FMA instruction set. Most instructions in that set have mnemonics like vfmadd231pd, but here rnd means something very specific. The Intel Software Development Manual documents it as: VFMADDRND231PD – Fused Multiply-Add of Packed Double-Precision Floating-Point Values…

I love building a startup in Rust but wouldn't pick it again
For almost two years now, the vast majority of our backend code was written in Rust (aside from a little bit of Python). I love Rust, it’s by far my favorite language. I find myself missing match in pretty much every other language I go to. However, if I was doing it over, I wouldn’t choose Rust. This advice is…

Rust to C compiler – 95.9% test pass rate, odd platforms
I am experimenting a bit with a new article format: instead of an overarching theme, this is more of a collection of smaller bits and pieces, sewn together.

Some programming language ideas
Programming languages seem to have somewhat stagnated to me. A lot of shuffling around ideas that already exist, not a lot of new ones.

A Desperate Plea for a Free Software Alternative to Aspera (2018)
I work at the Childhood Cancer Data Lab, where we use very big data to find cures for childhood cancers. To move data around the internet at very high speeds, we are forced to use a proprietary software suite called Aspera. If somebody could make a Free Software alternative, the future of the internet would be way…
