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.

WinDirStat (Windows Directory Statistics) is a disk usage statistics viewer and cleanup tool for Windows. On start up, WinDirStat reads the whole directory tree once and then presents it in three useful views: - The directory list, which resembles the tree view of the Windows Explorer but is sorted by file/subtree size, - The treemap, which shows the whole contents of the directory tree straight away, - The extension list, which serves as a legend and shows statistics about the file types. Visit the WinDirStat blog for more up-to-date information about the program. Note: If you are looking for an alternative to WinDirStat for Linux, then you are looking for KDirStat (apt-get install kdirstat on Debian-derivatives), and the alternative to WinDirStat for MacOS X is Disk Inventory X or GrandPerspective.

NSudo offers a series of System Administration tools and is based on SuperCMD, a software that allows you to run your program as SYSTEM with TrustedInstaller token. NSudo is a step up from SuperCMD in that it offers many other capabilities. Like SuperCMD it is also capable of launching programs with the TrustedInstaller access token, as well as the System access token and the current user access token. It can also launch programs with the current process access token with or without the LUA restriction. It supports launching programs with various specifications, such as specified privileges options, mandatory level (or integrity level) options, and process priority options. NSudo comes in multiple languages, with full DPI Support and accessibility support.

DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+) more details at: http://dar.linux.free.fr/doc/Features.html

This project now hosts the third-generation of Java SSH API, Maverick Synergy. This API builds on the Maverick Legacy commercial APIs and delivers a new API in a unified client/server framework. This API is available to the community under the LGPL open source license. This update includes ed25519 support, support for the new OpenSSH private key file format and stronger key exchange algorithms. The project continues to host both the original API and legacy applications created around it, however, these are now considered deprecated and we do not recommend their use in anyway.
