Names are not type safety

Almost…

SLS vs. Starship
NASA just announced the lunar landers for the Artemis program. To everyone’s surprise, SpaceX’s massive Starship is one of three landers NASA chose alongside Blue Origin and Dynetics.

Measuring keyboard-to-photon latency with a light sensor
For a long time when I’ve wanted to test the latency of computers and UIs I’ve used the Is It Snappy app with my iPhone’s high speed camera to count frames between when I press a key and when the screen changes.

Rust After the Honeymoon
Two years ago, I had a blog entry describing falling in love with Rust . Of course, a relationship with a technology is like any other relationship: as novelty and infatuation wears off, it can get on a longer term (and often more realistic and subdued) footing – or it can begin to fray. So well one might ask: how is…

An Intuition for Lisp Syntax
Every lisp hacker I ever met, myself included, thought that all those brackets in Lisp were off-putting and weird. At first, of course. Soon after we all came to the same epiphany: lisp’s power lies in those brackets ! In this essay, we’ll go on a journey to that epiphany.
