Remote Methode Call is a project to enable calls to methods in remote C++ classes. The transport is implemented as a library, and is free from dealing with the internal RMC stuff, so any C/C++ programmer is able to write a transport for his own purpose. RMC(2) currently has a sockets transport library as reference implementation. It is developed on Linux, and supports Linux on iX86 and PPC. RMC should also work on BeOS. Testers and developers are welcome to the project.
UAE is a mostly complete software emulation of the hardware of the Commodore Amiga 500/1000/2000. A Commodore Amiga, for those who don't know, is a 16/32 bit computer system based on the Motorola 680x0 CPU and a few specially designed custom chips that provide very good graphics and sound capabilities. Its first incarnation, the A1000, appeared in 1985, followed by the highly successful A500 and A2000 models. But if you didn't know, you probably don't want an emulator.
TestTrack Pro is a powerful defect tracking/bug tracking application. The application's server component runs on Linux servers and can be accessed by both Web and Windows clients. A full-featured defect management solution, TestTrack Pro includes multiple security configurations, integrated email notification, email importation, XML support, and much more. It easily scales from a single user to hundreds.
Lua FLTK is a binding of the FLTK widget set (www.fltk.org) to the language Lua (www.lua.org). It tries to make the use of FLTK widgets seem natural to Lua programmers. It uses a simple constructor syntax, remaps C++ values onto Lua conventions, and provides direct set/get access to widget properties.
bttvgrab is a program for grabbing video sequences using a bt848-based frame grabber card (e.g. Hauppauge WinTV, Miro PCTV...). The goal of bttvgrab is to provide high-quality grabbing suitable for video recording. Currently, this is accomplished by trying hard not to leave out a single frame, and to catch temproary delays by buffering several frames. In the future, synchronized sound will be part of it. Then you can create mpeg movies using mpeg2enc, the output files will be prepared for that, so that the conversion can be done by a simple shell script.
Calendars for the Web provides a server based calendar and scheduling application. It allows unlimited users to share unlimted events per calendar. Calendars for the Web comes with a full-featured browser based interface, is completely customizable (sixteen different calendar view types), fully documented, and supports online administration.
