luckyBackup is a powerful, fast, reliable, and fully customizable backup and sync tool. It can backup any directory (the source) to another (the destination). luckyBackup copies over only the changes you've made to the source directory and nothing more, saving a great deal of time for backups after the first one. Whatever changes you make to the source, including adding, moving, deleting, modifying files or directories, will have the same effect on the destination. Owner, group, time stamps, links, and permissions of files are preserved (unless directed otherwise). The synchronization feature works on any pair of directories, keeping the files that were most recently modified on both of them. It includes many safety checks to prevent accidental loss of data.
SolarCalc is a program for estimating the solar radiation and electrical energy yield in a given site around the world. The software has been written in Qt and uses the most recent models of solar radiation conversion by PV effects. The software can take into account many aspects of solar systems such as detailed diffuse/beam correlation models, temperature effects, and shadowing effects. The system allows you to build a user-based archive of components, like solar panels and inverters. Many printing and exporting functions are available, as well as ready-to-use PDF report export.
Ozirion is an experimental Web browser allowing people and groups to improve their privacy on the Internet by hiding their IP address through a network of virtual tunnels. The current release of Ozirion relies on the Tor technology. It includes a built-in Tor server and provides the ability to choose or ban countries in order to use an IP address from a specific country. The Privoxy local proxy is used for better privacy. Ozirion is totally independent from the Tor and Privoxy projects.
PySide provides a full set of Qt bindings and automated binding generation tools. The binding generation tools can be useful for creators of Python bindings to any Qt-based library or to any C++ library in general. Although based on a different technical approach, PySide will initially be API-compatible with existing Python bindings for Qt.
Soprano (formerly known as QRDF) is a library that provides a highly usable object-oriented C++/Qt4 framework for RDF data.

It has been optimized for easy usage and simplicity.
YUMRepoManager is a YUM configuration manager. It allows users to easily manage repository configurations, use most of YUM's options, enable and disable YUM plugins, and edit configuration files. It supports drag-and-drop of .repo files from and to your file manager, the option to change the createrepo arguments, and creation of a local repository from a directory which contains .rpm files or a YUM cache in a directory specified by the user. When finished, the YUM cache will be linked to the place where the repository has been created, unifying the YUM cache into a single folder, so that the packages installed after this point will be placed in this new path instead of the YUM cache.
