Making a Stainless Steel Rubik's Cube
I wasn't entirely satisfied with the aluminum cube , so after thinking about the design for a while, I decided to make another one out of stainless steel. Just for fun, I thought I would make all the pieces using only manual machines. How hard could it be?

What I learned in 2017 writing Go
A little over a year ago, I joined Cloud Foundry to work on Loggregator , Cloud Foundry's application logging component. Its core concern is best-effort log delivery without pushing back on upstream writers. Loggregator is written entirely in Go.

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.

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…

Must ride mule to and from work location
“David, this one, tell me about it …” He’d let me look at his domain name portfolio. Not names he owned and parked, but domains he owned & developed. This was another early project of his – a job board solely focused on the ranching industry. All aspects – cattle, outfitters, dude/guest, hunting, and even ... Read more

When not to use deep learning
I know it’s a weird way to start a blog with a negative, but there was a wave of discussion in the last few days that I think serves as a good hook for some topics on which I’ve been thinking recently.

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.

A Christmas tree bauble that plays Doom
Christmas is coming again, and generally that means christmas trees and everything in it: lights, streamers, and ofcourse baubles. The holiday is all very jolly and everything, so I decided it was lacking some doom... errm, I mean Doom. So I 3d-printed a small Christmas bauble modeled on an IBM PC, stuffed it with the…
