FBAC-LSM is a security mechanism for Linux which retricts applications based on the features they provide, such as "Web Browser" or "Image Editor". By restricting the actions of applications, the damage which can be caused by malware or software vulnerabilities can be significantly reduced. Reusable policy abstractions, known as functionalities, can be used to grant the authority to perform high level features (for example using the Web_Browser functionality) or lower level features (such as using the HTTP_Client functionality) or to grant privileges to access any specified resources. Functionalities are parameterized, which allows them to be adapted to the needs of specific applications. Functionalities are also hierarchical; that is, functionalities can contain other functionalities.
Quassel IRC is a modern, cross-platform, distributed IRC client, meaning that one or more clients can attach to and detach from a central core, much like the popular combination of screen and a text-based IRC client, but graphical. In addition to this unique feature, it aims to be a comfortable chatting program.
AstroAviBrowser is a small tool for astronomy imaging capture/processing. It allows you to open a video file, select the good frames, and save the new sequence in a new avi file using raw or lossless codecs. You may also de-bayer your frames and separate RGB plans. It's a kind of "AviRaw" for Linux.
DireKtion is a satellite navigation project based on data from OpenStreetMap.org. It aims to provide a free (not just as in beer) satellite navigation solution for any vehicle/person that can carry a Linux device. It is able to calculate a route between any two points on a map, and displays directions for traveling between them.
QSource-Highlight is a Qt4 front-end for GNU Source-Highlight. You can highlight your code on the fly, and have the highlighted output in all the formats supported by source-highlight (e.g. HTML, LaTeX, Texinfo, etc.). You can then copy the formatted output, and paste it (e.g. in your blog) or save it to a file. A preview of the highlighted output is available for some output formats (e.g. HTML, XHTML, etc.).
Trojita is a Qt IMAP email client. It is a pure Qt4 application with no additional dependencies. It has a robust IMAP core implemented using Qt's Model-View framework. Standards compliance is a design goal. It has support for bandwidth-saving mode aimed at mobile users with expensive connections. In addition to the usual SSL/TLS connections, the server can be accessed via SSH. It has on-demand body part loading, offline IMAP support, and safe dealing with HTML mail (actually more robust than Thunderbird's).
SynScope is an offline visualization and alignment tool for time-varying signals acquired from multiple sources that may differ in offset and/or sample rate. SynScope allows you to define reference points that correspond to identical events between source pairs. It then estimates the offset and resample rate to link these sources. It maps sample time from one source to the other via a link equation. Signal alignment can be inspected with synchronous visualization or resampling. With synchronous visualization, linked signals scroll together according to the link relation. With resampling, linked signals are resampled to the highest sample rate and offset-compensated.
YAGF is a graphical frontend for the cuneiform and tesseract OCR tools. It lets you open already scanned image files or obtain new images via XSane (scanning results are automatically passed to YAGF). Once you have a scanned image you can prepare it for recognition, select particular image areas for recognition, set the recognition language and so on. Recognized text is displayed in an editor window where it can be spell-checked, corrected, saved to disk, or copied to clipboard. YAGF also provides some facilities for a multi-page recognition.
