jHepWork (jWork) is an environment for scientific computation, data analysis, and data visualization for scientists, engineers, and students. The program is fully multi-platform (written in Java). Programs can be written in the Java, Jython/Python, and BeanShell scripting languages. Matlab/Octave is supported for symbolic calculations. The program can be used to display data and functions in D and 3D. It comes with a friendly IDE and a code assist.
astateful is a unique approach to Web development. It incorporates a solid theoretical foundation based on Dynamic Programming in which a Web site is programmed in such in a way that it can be "solved" using a 'top down' or 'bottom up' approach. It is very scalable. Caching and encryption are included by default. It has a steep learning curve.
The PDM library aids in inspecting and managing Python programs running as daemons, allowing client programs to connect to the daemon process in order to interact with it in various ways. Primarily, it provides an interactive read-eval-print loop, and a non-interactive programmatic interface not entirely unlike Java's JMX.
New Internet is an all-purpose resilient serverless network system that overcomes the distinction between "server" and "client" and extends the idea of peer-to-peer networking to any kind of application or service. It implements a growing set of protocols and could be used for direct file transfer or as a serverless mail network.
