jHepWork ("jWork") is an interactive environment for scientific computation, data analysis and data visualization designed for scientists, engineers and students. The program incorporates many open-source math software packages into a coherent interface using the concept of scripting, rather than only-GUI or macro-based concept.

jHepWork can be used with several scripting languages for the Java platform, such as Jython, (the Python programming language), JRuby (the Ruby programming language) and BeanShell. This brings more power and simplicity for scientific computing. The programming can also be done in the native Java.

Ace is a standalone code editor written in JavaScript. Our goal is to create a web based code editor that matches and extends the features, usability and performance of existing native editors such as TextMate, Vim or Eclipse. It can be easily embedded in any web page and JavaScript application. Ace is developed as the primary editor for Cloud9 IDE and the successor of the Mozilla Skywriter (Bespin) Project.

The Mozilla Skywriter project (formerly Bespin) is a Mozilla Labs experiment to explore ideas around “coding in the cloud”. We’re happy to announce that the project has found a new, permanent home as part of the Ajax.org Cloud9 Editor (Ace) and Cloud9 IDE projects. Read on to hear more about the transition and what we’ve learned along the way.

The audio file editor, baptised 'Eisenkraut', came into existance (as a scaffold) during a project class on audio programming in Java at the SeaM in Weimar. It is distinguished by a number of traits which makes it particularly interesting in the field of computer music: There are no restrictions with regard to the number of channels in a file, and there is an OSC interface via which the functionality can be extended, for example using the SuperCollider language. Possible applications of such extensions are the transfer of marker information or the maintainance of meta data for segmented files, the algorithmic editing (cut/copy/paste) of files, or the addition of your own sound transformations or special decoders (e.g. an MS matrix).
