Porcupine is an open source object oriented Web application server that features an integrated transactional object database, the Porcupine Object Query Language and QuiX , an AJAX powered XML user interface language.

The HelenOS project is an effort to develop a portable operating system with some experimenting and research in mind. HelenOS supports SMP, multitasking, and multithreading on 32-bit and 64-bit, little-endian and big-endian processor architectures, among which are AMD64/EM64T (x86-64), IA-32, IA-64 (Itanium), 32-bit MIPS, 32-bit PowerPC, and SPARC V9. The extent to which these architectures are supported differs from architecture to architecture. Some run on real hardware, and some run only in a simulator.

Lightweight 100% Java SQL Database Engine

J2ME Polish is suite of tools for creating "polished" J2ME applications.
Each tool meets a definite need of J2ME developers: Build-tools with an integrated device-database, a powerful GUI, a framework for building localized applications, a game-engine, a logging framework and a collection of utility classes and tools.

Joone (Java Object Oriented Neural Engine) is an artificial neural network Java framework. It can be used to build and train neural networks with a powerful visual environment. It has a modular design and can be easily extended by writing new modules to implement new learning algorithms or architectures.

infoRSS is a lightweight, non intrusive, RSS, ATOM, NNTP and HTML headlines reader for Firefox, Mozilla, Netscape and thunderbird, designed by Didier Ernotte. The extension installs a small icon (looks like an earth) in the status bar. The headlines are displayed in the beside this icon in the status bar or in a separate bar (top or bottom of the screen). The interface is very simple to use: drag and drop new url of feed onto the extension icon to add a new feed or click on the extension icon to select a specific feed to read. The feeds can be grouped to allow multi feed fetch and filter can be used to limit the number of headlines.

Ultimate++is an attempt to provide the optimal development platform. By utilizing of new ideas in C++ development, Ultimate++ achieves significant reduction of code complexity for most applications when compared to other development platforms.

The goal of the Ibis project at the Vrije Universiteit Amsterdam is to design and implement an efficient and flexible Java-based programming environment for Grid computing, in particular for distributed supercomputing applications. Java has many advantages for Grid computing. It is inherently more portable than traditional, statically compiled languages, making it much easier to execute Java applications in a heterogeneous Grid environment. Also, Java is based on a high-level, object-oriented, type-safe programming model and it has built-in support for multithreading and distributed computing.

Unfortunately, Java's support for distributed computing, Remote Method Invocation (RMI), has important shortcomings for high-performance Grid computing: it is difficult to implement efficiently and only expresses client-server style communication. Ibis addresses the first problem by providing by providing a faster RMI implementation. Ibis also addresses the lack of expressiveness of Java RMI. The Ibis programming environment supports a range of programming and communication paradigms, integrated cleanly into Java. Other systems typically resort to extensions that are less well integrated with Java's object-oriented model, such as using a native MPI library.

In addition to RMI, Ibis currently supports the following programming models:

GMI provides group communication and collective communication.
Satin provides a divide-and-conquer style programming model.
MPJ provides a pure Java implementation of the MPI Message

Passing Interface.

VMPC is a family of cryptographic algorithms designed by Bartosz Zoltak. The algorithms provide simple to implement, fast and secure methods of symmetric data encryption (VMPC Stream Cipher), key scheduling (VMPC Key Scheduling Algorithm), and message authentication (VMPC-MAC scheme). The VMPC algorithms were publicly presented at an international cryptography conference FSE'04 in India. The project also includes the VMPC Data Security application, which is based on the algorithms. It enables to encrypt files/folders/emails, unrecoverably wipe files from disk and generate hard-to-break passwords from random mouse moves. The basic version of the application for home purposes can be downloaded for free from www.VMPCfunction.com
