The Omega Project is a universe simulator accessible remotely by registered users over the JSON-RPC protocol. This allows the highest number of users and developers to access the universe and control ships / stations / other entities in via many mechanisms. The server listens for requests over a variety of protocols including TCP, HTTP, Websockets, AMQP, and more, and clients written in any language running on any platform may use these transports to communicate with it. Omega also ships with a WebGL frontend based on three.js, providing an interactive view into running simulations.
HHVM (aka the HipHop Virtual Machine) is a virtual machine designed for executing programs written in Hack and PHP. It uses a just-in-time compilation approach to achieve superior performance while maintaining the flexibility that PHP developers are accustomed to. To date, HHVM (and its predecessor HPHPc before it) has realized over a 9x increase in Web request throughput and over a 5x reduction in memory consumption for Facebook compared with the PHP 5.2 engine + APC. HHVM should be used together with a FastCGI-based Web server like Nginx or Apache.
