Kaspaliste is a knowledge database which handles all types of books, articles, journals, webpages, etc.
This program is BETA software! It is based on a reliable database server, so complete data loss is not very likely. But other (hopefully minor) problems may occur. BACKUP YOUR DATABASE FRREQUENTLY AND KEEP OLD BACKUPS! I think its obvious: Im not a native english speaker. Corrections are welcome.
Kaspaliste is a literature database. It handles all kinds of books, articles, journals, webpages etc. The database goes beyond storing bibliographical information. There is the possibility to create annotated links between pieces of information (like the content of a book chapter) and to group links into categories.
The user interface works just like a web browser: You may follow the links to open records. You may walk back and forward through previously edited records, change fields, and create or delete links, publication, authors etc. on the fly with just one mouseclick.
Kaspaliste does not only store pieces of information about publications. It stores files as well. Kaspaliste handels various formats like html, pdf, ps, dvi and pictures (depends on your KDE-installation since the kpart-technology is used). You can for example store ocred parts of interesting publications. The fulltext search covers these files.
Another feature is the automatic generation of BibTex files.
Enhancements:
- circumvents a bug in the pdf-KPart.
- bugfix release for kde 3.2

Google Hacks project is a compilation of carefully crafted Google searches that expose novel functionality from Googles search and map services.

For example, you can use it to view a timeline of your search results, view a map, search for music, search for books, and perform many other specific kinds of searches.

FMS stands for Fully Modular Synthesizer and is a tool to create all kinds of sounds from scratch.
You can play and sound (sine, triangular, etc.) with any property settings (frequency or volume) and modulations thereof.
It also features tools to save sounds, play .MUS music, graphically display sounds, and make real noise.
Main features:
Playing sounds
- with any frequency and volume
- one after another or at the same time (mixer) or both
- stereo (different sounds on different channels)
- like speech synthesis
- both on-the-fly playing with direct user access and asynchronous, pre-computed output
- with all modulation options described below
Making noise
- now although it tends to get noisy in any way, we mean real noise here
- in 4 different ways
- nearly-white noise
- narrow band noise
Modulating
- amplitude (volume)
- frequency
- minima, maxima, amplitude and frequency of the modulation (here the "Fully Modular" comes to existence)
- narrowness of the noise frequency band - experimental
Making music
- some-kind-of-midi-mapping mode (sound + envelope => instrument, FMS midi file format)
- auto-converter and player for MUS file format (Musplay)
- auto-composer for those who like a rather modern kind of music - experimental
- chords - experimental
Displaying
- spectrum of a sound
- oscillogram of a sound
Saving
- sounds as oscillograms in FMS file format (mathematical description, not complete wavetables)
- sounds as Fourier overtone amplitudes
- music in FMS midi format
- FMS output in wave format
- wave file sounds in FMS file format (auto-converter) - experimental
GUI
- a somewhat ugly and extremely limited tcl/tk gui
- FROCOR, an installation that connects the FMS sound backend to graphical interfaces and outputs
- a fully modular Qt GUI - experimental
Enhancements:
- synchronous mode (no more waiting!)
- bugfixes (no more screaming!)
- unscrewed display tools (no more segfaulting!)
- improved exacticity (no more discalculating!)
- UDS controlled sound backend (no more stupid jokes!)

libEtPans purpose of this mail library is to provide a portable, efficient middleware for different kinds of mail access.
When using the drivers interface, the interface is the same for all kinds of mail access, remote and local mailboxes.
libEtPan! project can read mbox, MH format, and Maildir mailboxes, and does MIME parsing.
Installation:
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.
Running `configure takes awhile. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Optionally, type `make check to run any self-tests that come with the package.
4. Type `make install to install the programs and any data files and documentation.
5. You can remove the program binaries and object files from the source code directory by typing `make clean. To also remove the files that `configure created (so you can compile the package for a different kind of computer), type `make distclean. There is also a `make maintainer-clean target, but that is intended mainly for the packages developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.
Enhancements:
- This release is just a bugfix release for the compile errors in 0.50, namely with enabled SASL, GnuTLS, and BIOs handling with openSSL.

FullSync is a universal file synchronization and backup tool which is highly customizable and expandable. It is especially for developers, but the basic functionality is easy enough for everyone.
Main features:
Publication and update of websites, synchronization of local directories and making backups of your data.
- Because of the large amount of options provided, you can use FullSync to publish and update websites, synchronize files between your pc and your notebook or even backup files to a storage device every few hours.
multiple modes: update destination, synchronize source with destination
- FullSync can be configured to look for changes in different ways. you can decide to make it look only on source changes, or both, source and destination or only on the destination. Additionally you can decide whether deletions should be performed or just reported.
flexible rules, allowing all kinds of exclusion/inclusion
- The rules that can be defined are very powerful. For example pattern matches can be regular expressions and you can first tell FullSync which files to take and can then define exceptions. Additionally you can configure criterias which decide whether a file has changed or not. This is good when using filesystems which can not set modification times or where the size changes while transferring from the source to destination (ftp).
configuration and rule-rewriting per directory possible
- For advanced configuration you can deploy xml files in the synchronized paths which can overwrite the rules for this branch. So you could for example change the synchronization direction for a single directory, or you could change filters or even disallow rule rewriting.
buffered filesystems (so the tool only sees files it created itself)
- To allow updating just the important parts or a directory tree, FullSync can buffer the view of the destination filesystem and keeps track which files it transferred. This way additional files on the destination are ignored and changes on destination files can be reported. Reporting or finding changes will be implemented for the source later.
multiple protocols (FTP,SFTP,SMB...)
- The structure of FullSync makes it easy for a developer to add new types of filesystems, which can be used as source or destination in the synchronization process. Currently local files, ftp, sftp and samba are supported. Zip is planned.
read/write access bufferable and multithreadable
- The way the file data is copied is very customizable. This allows to use a buffer which loads large masses of source data into the memory and writes it all in one run if the buffer is full. That reduces harddisk-jumps and is especially good for making backups or synchronizations on one harddisk. For updating webpages multithreaded writing is good for using full bandwidth.
Enhancements:
- added compatible and passive url-query options to ftp urls compatible=true should solve the problem with - and spaces in paths (bug #1090385) this really needs gui support !
- added FullSync internal logging (say loggers per class,...)
- corrected logging.xml
- added French localization

VideoJack is a patched Jack audio server supporting video. Unicap VideoJack plug-in is a VideoJack client that can generate a video out connection for all devices supported by unicap.
The client was tested with the jack_video_output client and with LiVES. libunicap and libunicapgtk need to be installed for this client to work.
About Unicap:
unicap provides a uniform API for all kinds of video capture devices. The API was designed keeping simplicity in mind so that developers can focus on their actual image processing tasks when using video capture devices.
Device drivers are handled via a plugin mechanism. Support for new devices can be added on the fly, without recompilation of the library. The API remains the same for each device so that an application using unicap immediately works with all devices supported by unicap.
unicap is distributed under the terms of the General Public License (GPL).
Commercial licenses are available for projects planning to use unicap but should not be released under the terms of the GPL.
Enhancements:
- This release adds a command line client and the ability to save and restore the device state.
