Op Color Plots
A lot of my work involves staring at visualizations trying to get an intuitive feeling for what a system is doing. I’ve been working on a new visualization for Jepsen, a distributed systems testing library. This is something I’ve had in the back of my head for years but never quite got around to.

Inkwell Games
Inkwell Games bills itself as “Daily puzzles worth thinking about” and that’s a great tagline. Right now they offer two daily puzzles: Stars and Fields. Both are enjoyable but I rank Stars as a bit above Fields but as I get better at understanding the patterns of Fields it’s growing on me each day.

Clues by Sam
Clues By Sam is a daily puzzle game where you get to uncover a criminal conspiracy by following the clues… made by Sam… err… Johannes. It’s a little if-this-then-that logic puzzle where Pam implicates Bob as a criminal and because Bob is a plumber and there’s one innocent plumber then Sally is innocent. It starts simple but overtime but often the clues will feel like they lead to a dead end… but there’s always a way to solve the puzzle. It has a sudoku-like quality to it. Like the NYT crossword...

Deeper than the Skin
Ariadne saw two kinds of people leave the brain tattoo parlor: she could tell them apart by the type of hope in their eyes. Some looked eagerly at everything in the hope that it would trigger the Proustian payload they had paid the parlor to build random associations for. Some, it was clear from the frozen curve of their necks, had spent a long time trying not to look at anything. They were glancing skittishly at random things now, afraid they would trigger the payload they had come to regret, h...
