Deme is a Web tool to host asynchronous meetings including discussions, document comments and collaborations, straw polls, and decision- making for small to medium groups of people.
It also provides features useful for groups including file storage, member lists, and the like. It is intended to create an environment to allow participation and help strengthen organizations critical to civil society.
Deme is free software, licensed under the AGPL, for asynchronous interactions that include discussions, document collaboration, polls and decision making among small to medium sized groups of people. Our intent in creating Deme is to support the type of deliberation critical to the functioning of smaller, informal organizations in civil society. Read the Deme white paper (pdf format) for more detail on the priciples behind Deme.
Enhancements:
- Full email integration and interface tweaking along with standard bugfixes.

wGui is a platform independent dialog management library based on SDL (Simple Direct-Media Layer) and Freetype 2.
wGuis purpose is to fill the small niche of a GUI library for SDL. There are actually three well known alternatives: LibUta, ParaGUI and aedGui. wGui was spawned from the work of another project (as was LibUta), which I may someday actually get back to.
This was designed to have as few dependencies as possible, and currently only relies upon SDL and Freetype. There is also no platform dependent code, which means it should work properly on any platform that has SDL and Freetype.
wGui was also designed to take advantage of C++, the Standard Library, and the latest Object Oriented techniques. Unfortunately both SDL and Freetype are regular C projects, so not everything is strict C++.
Enhancements:
- The big change in this release was to support Unicode.
- Support for building in Microsoft Visual Studio 2005 has also been added.

Jimm is a native ICQ clone for Java 2 Platform Micro Edition (J2ME), Mobile Information Device Profile (MIDP) 1.0 and 2.0 . It supports the new v8 protocol, former protocols are not supported.

Jude is a rapid application development tool that permits to formalize a problem and then obtain a full featured and easy to use data management, workgroup application that can be further adapted implementing specific agents.

Jude is based on a knowledge-base with an object-oriented structure on the server side and a compound-document, agent-based user interface on the client side.

Relational database, Object-Oriented database, document-management systems, XML documents, compound-documents, declarative programming, agent-based systems and Java are well understood technologies but when you use them alone in order to build data-management applications you encounter many problems.

For example relational databases management systems cannot support new data types and for some applications the allowed data are not sufficient. They lack support for long-transactions.

The development of an application using object-oriented database management systems encourages procedural coding over declarative coding and this tends to produce code hard to maintain because there are many relationships between different parts of the program. Jude tries to join all benefits of these technologies in a coherent application framework.

Jude permits developers to specify an abstract, simplified view of the world we wish to represent using an high-level, declarative, object-oriented language and then to obtain a full functional work-group application. Jude try to join in a simple but powerful way many powerful programming paradigms: object-oriented, declarative, agent-based and compound-document.

Developers can extend application functionalities adding new agents to the system. Developers can reuse already specified knowledge-base clusters (there are already clusters related to physics, organization relationships, chemical). Developers can reuse already specified agents, in particular agents related to user interface.

Jude permits users to manage (view, edit, retrieve) documents and structured informations using a coherent and simple to grasp environment based on Java and Swing library.

The Prex project is an open source initiative to provide a portable real-time operating system for embedded systems.
This project originally started to make a royalty-free OS for mobile phones and PDA in order to spread open source movement to such proprietary OS field. And now, the project target has been shifted to the wider area of real-time and embedded systems.
Prex is designed specifically for small memory footprint platforms. It is written in C language based on traditional micro-kernel architecture. The Prex kernel provides only fundamental features for task, thread, memory, ipc, exception, and synchronization.
The other basic OS functions, process, file system, application loading, and networking, are provided by the user mode servers. In addition, Prex provides a POSIX emulation layer in order to reuse the existing applications.
Prex is an open source royalty-free OS for mobile phones and PDA.
This design allows system to perform both of the native real-time task and the generic *NIX process simultaneously without degrading the real-time performance. Furthermore, it helps the platform designer to construct OS by choosing suitable server tasks for their target requisition.
Prex is royalty-free software released under BSD License
Main features:
- Task and thread control: preemptive priority scheduling with 256 priority levels
- Memory management: virtual address mapping, shared memory, memory protection, with MMU
- IPC: synchronous message passing among threads, object name space in kernel
- Exception: framework for POSIX signal emulation
- Synchronization: semaphores, condition variables, and mutexes with priority inheritance
- Timers: sleep timers, alarm timers
- Interrupt: nested interrupt service routines, and prioritized interrupt service threads
- Device I/O: minimum synchronous I/O interface
- Real-time: low interrupt latency, high resolution timers, periodic timers, and scheduling quantum control
- Cross platform portability: well defined architecture dependent layer and driver-kernel interface
- Modular design: OS servers and BSP module separated from kernel
- Small memory footprint: kernel size < 25k bytes
- Low power consumption: control of processor idle state, support of DVS (Dynamic Voltage Scaling)
- Disk-less: on-core kernel, no memory page swapping
- Instantly available: minimal OS boot time, system suspend/resume, kernel warm restart
- File systems: VFS framework, RAM/FAT/Flash file systems optimized for embedded systems
- Networking: TCP/IP stack, BSD socket interface

Pydar is a digital audio recorder providing scheduled recording of radio programs. It provides scheduling recording of radio programmes. Pydar can compress programmes on the fly into either Ogg Vorbis or Ogg Speex formats as well as recording to uncompressed Microsoft WAV files. Pydar is free software licensed under the GNU General Public License.
Pydar will run only on GNU/Linux or similar operating systems which have the Linux binary interface exactly (pydar directly uses the kernel interface to tune the radio.
Pydar requires Python >= 2.2 (probably), PyGTK >= 2.0.0, Libglade >= 2.0.0 to run together with at and sox to schedule recordings. Pydar does not require any GNOME specific libraries but does follow the GNOME Human Interface Guidelines (please report deviations from the HIG as bugs).
Users running Redhat GNU/Linux 9.0 must upgrade PyGTK before pydar will function correctly. The RPMs provided in Fedora Core (pygtk2, pygtk2-devel, pygtk2-libglade) have been tested and are known to work.
Enhancements:
- TODO, pydar, src/pydar.glade, src/pydar/gui.py, src/pydar/tuner.py: Added a few warning/confirmation dialogs. Added a few beeps when dumb stuff happens. Improved error reporting by being more conservative about swallowing exceptions
