PraxisCORE is a modular JVM runtime for cyberphysical programming, supporting real-time coding of real-time systems. It is the heart of PraxisLIVE. With a distributed forest-of-actors architecture, runtime code changes and comprehensive introspection, PraxisCORE brings aspects of Erlang, Smalltalk and Extempore into the Java world ... a powerful platform for media processing, data visualisation, sensors, robotics, IoT, and lots more!
