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.

Mocking time and testing event loops in Go
Initially I wanted to write articles on those two topics separately (mocking time and testing event loops), but during the process I realized that the things I want to talk about are too interrelated: when I need to mock time, it's usually to test some event loop with it, and when I test event loops, typically mocked…
