Greenfoot is an integrated development environment that makes it easy to write games and simulations in Java. It comes with a broad range of demo scenarios and documentation that gets newcomers started very quickly. Greenfoot may be used to learn or teach programming, or just to write a cool game and maybe put it up on a Web site. (it can export the game to a Web page). It was originally developed for school age learners, but is now used by all age groups.
CryptoCD is a collection of user-friendly documentation for software that provides secure communication through the Internet. The programs cover tasks like email encryption, secure chat, and anonymous Web browsing. CryptoCD comes with comprehensive documentation explaining step by step installation and use of the software for inexperienced users. At the moment, the documentation is only available in German.
The massXpert software package is a mass spectrometry environment for linear (bio-)polymers. It inherits all the innovations of GNU polyxmass. It allows the detailed definition of new polymer chemistries in the XpertDef module. These chemistry definitions are then used in the desktop calculator-like mass calculator (XpertCalc) and in the sophisticated polymer sequence editor and (bio-)chemical/mass spectrometric simulations module (XpertEdit). Available simulations include polymer and monomer chemical modifications, polymer sequence cleavage, gas-phase fragmentation, m/z ratio calculations, and more.
iDMC is user-friendly software for the simulation and analysis of non-linear models. It was designed both as a teaching and research tool, and is very easy to use (a user’s guide is available). Numerical calculations are performed on models included in the package, or any model formulated by the user and easily encoded (a few lines with no compilation necessary). The Java graphical user interface provides fast generation of graphical data of good quality, which can be saved as .png files. Hard computational tasks are delegated to a separate, small C library.
Vocatra is a console-based vocabulary trainer. It takes one or more vocabulary files, queries you for each word, and lets you try to give the correct answer. You can enable different learning modes. If you prefer to learn sequentially it has an order mode. Otherwise, there is also a random mode available.
