Discovering a JDK Race Condition, and Debugging It in 30 Minutes with Fray
Discovering a JDK Race Condition, and Debugging it in 30 Minutes with Fray I’ve been adding more integration tests for Fray recently. To ensure Fray can handle different scenarios, I wrote many creative test cases. Many of them passed as expected, while some failures led to epic fixes in Fray. Then something…

Interfaces – The Most Important Software Engineering Concept
An interface can be thought of as a contract between the system and the environment. In a computer program, the 'system' is the function or module in question, and the 'environment' is the rest of the project. The interface formally describes what can pass between the system and the environment. An 'implementation'…

Unpacking Elixir: Real-Time and Latency
Elixir was built on Erlang. Erlang was built to provide "consistently low latency" and a few other audacious goals. Note, this is not a hard realtime constraint. It is soft, squishy and yet, important and real. It makes Erlang unusually suitable to systems where latency matters and where a near-realtime experience is…

Preload, prefetch and other link tags
There’re lots of ways to improve web performance (see Web Performance 101 for a full overview). One of those ways is to preload content you’ll need later in advance. Prefetch a CSS file, prerender a full page, or resolve a domain ahead of time – and you won’t have to wait for it when it’s actually needed! Sounds cool.
