title Constraint System dated Fall 2023 author Summary of work on relax-pk At the beginning of phase 2, we weren’t sure what to do about constraints. Based on past exploration, constraints seemed to hold a lot of promise but were notoriously unreliable. A good constraint system could unify and power a number of key aspects of the dynamic medium we seek. It would allow for mechanical constructions, like a rope and pulley, that feel physically correct. It would allow for a computational model tha

Summary Introduce scoped values, which enable a method to share immutable data both with its callees within a thread, and with child threads. Scoped values are easier to reason about than thread-local variables. They also have lower space and time costs, especially when used together with virtual threads (JEP 444) and structured concurrency (JEP 505). History The scoped values API was proposed for incubation by JEP 429 (JDK 20), proposed for preview by JEP 446 (JDK 21), and subsequently impro

ASCII lookup utility in Ada When working with old digital synthesizers from the 1980s and 1990s (and some newer ones too) I often have the need to quickly look up the identity of a byte that seems like an ASCII character code. For example, in MIDI System Exclusive format files there are often names of sound patches or "voices". When writing programs to process these formats it is handy to do a quick check, because even (or especially?) after nearly 40 years at this thing I still haven't memoriz

Websockets are powerful tools that have become a fan-favorite for building realtime applications, but you might be using them for all the wrong reasons. Let's explore the pitfalls of websockets and how we can use plain old HTTP to get the same job done. What’s a WebSocket?
