The DUP System is a language for productive, parallel, and distributed stream processing on POSIX systems. Programming with DUP is similar to writing shell scripts with pipes except that filters can have multiple inputs and outputs. Furthermore, the computation can be spread across multiple computers. A distinguishing characteristic of DUP compared to other streaming languages is that filters can be written in almost any programming language. The DUP System distribution includes the runtime system and a collection of over a dozen multi-stream filters.
Falcon is a simple, fast, and powerful programming language, easy to learn and to feel comfortable with. It is also a scripting engine, easily embeddable in any complex, multi-threaded and mission-critical application. Falcon provides its users with four integrated programming paradigms: procedural, object oriented, functional, and message oriented. And you don't have to master all of them; you just need to pick the paths that are ingredients you prefer, and let the code to follow your inspiration.
Mutabor is a program that allows you to perform and compose microtonal music using a normal MIDI keybord and normal MIDI equipment. Its powerful description language is intended to allow permanent retunings and complex tuning logic. One application is just tuning. Mutabor has been used for this purpose to make available all pitches that can be reached by stacking perfect thirds and perfect fifths. The stable version 3.0x is available in German only and runs under Windows and Wine. The unstable branch can be accessed via CVS (but build bugs should be expected) or downloaded from the Berlios developer site.
Hormiga is a language designed to be simple and powerful, allowing users without software programming knowledge to make the programs needed to automate the calculations of everyday problems. Generally, it is necessary only for the users to be aware of the problem they want to solve. The language allows programmers to focus on the problem and not to worry about the interactive interface with the user. The programmer will have to state the instructions to solve a problem, in the same way they would do manually. The steps may depend one upon the other. Like most languages, Hormiga has support for functions and the possibility of creating libraries of commonly used code. Unlike most languages, Hormiga automatically and dynamically creates the graphical user interface (GUI) for programs, has support for calculating definite integrals in multiple dimensions, and incorporates a new concept called Step, similar to a procedure of Pascal, but allowing you to state dependences between them.
The Objeck computer language is an object-oriented computing language with functional features that has ties with Java, C#, and Pascal. In this language, all data types are treated as objects. The language consists of a compiler and VM with an accompanying memory management and JIT compiler.
OpenTeacher is a vocabulary training application that helps you learn a foreign language. It uses a list of words in both a known and a foreign language and tests you. It supports smart question asking and interval training with Think answers, shuffle answer, and repeat answer input modes. It has easy symbol, Greek, and Cyrillic input, and reads and writes T2K (Teach2000) and WRTS files, and reads ABBYY Lingvo Tutor files. It is available in Arabic, Australian English, Brazilian Portuguese, Chinese (Traditional), Croatian, Czech, Danish, Dutch, French, German, Hebrew, Hungarian, Japanese, Korean, Polish, Russian, Serbian, Slovenian, Spanish, Swedish, and Turkish.
