EZ Red Skin Fix is a script-fu based on a technique by lylejk of dpreview.com that can be used to improve skin that has a reddish tint.

Database Functions is a PHP class that can be used to build and execute MySQL database queries.

It can build SELECT, INSERT, UPDATE and DELETE queries from lists of parameters and values.

The class can also execute the generated queries and retrieve the SELECT query results into associative arrays.

burnCDDA is a console frontend to cdrdao, cdrecord, mpg123, oggdec, mppdec, normalize, and mp3_check.

It can be used to create audio CDs from an M3U playlist (the playlist format of XMMS).

burnCDDA supports MP3, Musepack, OGG Vorbis and WAV files, and it might be the easiest way to copy an audio CD.

NameSpawner can be used to generate random names with a specific theme. Some of the themes included in the main distribution are: elvish, barbaric, dwarvish, angelic, demonic, and Tolkien-like.

Names are "spawned" via random walks on Markov Chains. New themes can be created using existing lists of names. Random walk settings can be tweaked to obtain more variance in the output names or more faithfulness to the original list of names.

BpmDj is a program that can be used to DJ. It works under Linux and plays Mp3s/Oggs. It has a fully automatic BPM counter.
It can determine the sound color. BpmDJ project has a full fledged QT based interface. It will help you manage a large amount of songs. Further it can help in creating playlist and has proven to be very robust.
The program also allows offline automatic mixing and contains a wavelet based beat graph analyzer to visualize audio tracks.
Enhancements:
- This version was ported to Qt4.

GUASI library implements a thread based generic asyncronous execution engine, to be used to give otherwise syncronous calls an asyncronous behaviour. GUASI comes from Generic Userspace Asyncronous Syscall Interface.
It can be used to wrap any syncronous call, so that it can be scheduled for execution, and whose result can be fetched at later time (hence not blocking the submitter thread).
The GUASI library can be used as complement to standard event retrieval interfaces like poll(2), select(2) or epoll(4).
Enhancements:
- The GUASI handle creation API was changed to remove the stack size.

Image rotator can be used to automatically detect and rotate landscape/portrait photos from digital cameras.
Currently, only outdoor photos are recognized. Image rotator is a command line tool which uses an artifical neural network to detect the orientation of images. Image reading, scaling, and rotation are done with the ImageMagick library.
Enhancements:
- The --verify option can now be used to decrease the number of false decisions.
- This is done by running the image three times (original, rotated left, rotated right) through the neural network.
- A small memory leak was fixed.

bench is a tool that times how long an application was running.

The project can be used to test algorithms for speed changes, since it counts in microseconds.
