    TortoiseSVN

    TortoiseSVN

    An Apache SVN client, right where you need it most

    TortoiseSVN is a Subversion (SVN) client, implemented as a windows shell extension. Which means it's available right where you need it: in the Windows file explorer. It's intuitive and easy to use, since it doesn't require the Subversion command line client to run. Simply the coolest Interface to (Sub)Version Control!

    TurboVNC

    TurboVNC

    High-speed, 3D-friendly, TightVNC-compatible remote desktop software

    TurboVNC is a high-performance, enterprise-quality version of VNC based on TightVNC, TigerVNC, and X.org. It contains a variant of Tight encoding that is tuned for maximum performance and compression with 3D applications (VirtualGL), video, and other image-intensive workloads. TurboVNC, in combination with VirtualGL, provides a complete solution for remotely displaying 3D applications with interactive performance. TurboVNC's high-speed encoding methods have been adopted by TigerVNC and libvncserver, and TurboVNC is also compatible with any other TightVNC derivative. TurboVNC forked from TightVNC in 2004 and still covers all of the TightVNC 1.3.x features, but TurboVNC contains numerous feature enhancements and bug fixes relative to TightVNC, and it compresses 3D and video workloads much better than TightVNC while using generally only 5-20% of the CPU time of the latter. Using non-default settings, TurboVNC can also be made to compress 2D workloads as "tightly" as TightVNC.

    vJoy
    This project was originally designed to provide an open-source replacement for PPJoy. The product, at this point, consists of virtual joystick devices that is seen by the system as a standard joystick but its position-data is written to it by a feeder application. An existing feeder application that takes advantage of this product is SmartPropoPlus. If you are an application writer you can very easily write an application that controls a joystick (e.g. mouse-to-joystick, keyboard-to-joystick). If you are a beginner in device drivers you can take this code and enhance it to support more (or less) axes, buttons or POVs.
