Write NOW, Run Anytime
summary
Live coding system built on NetBeans called Praxis LIVE supports real-time Java hot-reloading by compiling class bodies in memory with a fresh classloader per edit, splitting identity/state/code so crashes fail fast. Runtime uses a forest-of-actors runtime with graph-root mailboxes, process-splitting for low-latency audio/video, and a 48 kHz Java synthesis path. Demo includes hardware I/O (TinkerForge), Processing/GL shaders, and a working single live-coded Java lambda that mangles the Amen drum loop live.
