GNOME Speech is a simple general API for producing text-to-speech output.

KMag is a small utility to magnify a part of the screen. KMag is very useful for people with visual disabilities and for those working in the fields of image analysis, web development etc.

KMouseTool clicks the mouse whenever the mouse cursor pauses briefly. It was designed to help those with repetitive strain injuries, for whom pressing buttons hurts.

KMouth is a program which enables persons that cannot speak to let their computer speak, e.g. mutal people or people who have lost their voice. It has a text input field and speaks the sentences that you enter. It also has support for user defined phrasebooks.

Papi, the Python Accessibility Programming Interface, is a Python wrapper around the GNOME ATK toolkit. It allows a developer to make python objects and applications easily accessibility aware without the need to install PyGTK and the GNOME accessibility components. Instead it only depends on ATK and - on the developers behalf - the ATK/AT-SPI bridge shipped with AT-SPI.

AdvanceCOMP is a collection of recompression utilities for your .ZIP archives .PNG snapshots .MNG video clips .GZ files The main features are: * Recompress ZIP, GZ, PNG and MNG files using the Deflate 7-Zip implementation * Recompress MNG files using Delta and Move optimization

amigadepacker depacks compressed Amiga formats. PowerPacker, XPK SQSH, MMCMP and StoneCracker 4.04 (S404) formats are supported. Amigadepacker will automatically determine the compressed format by content. Among other things, the tool is useful for playing packed Amiga music formats with uade.

Bicom is a data compressor in the PPM family. It is freely available and Open Source. Its most unique characteristic is that compression with bicom is completely bijective -- any file is a possible bicom output that can be decompressed, and then recompressed back to its original form. Of course, any file is also a possible bicom input that can be compressed, and then decompressed back to its original form. To support encryption applications, bicom also includes a passphrase-protection option that will automatically encrypt after compressing, or decrypt before decompressing.

Use of bzip2, which is intended to replace bzip, is recommended. The algorithms used in bzip2 are different and incompatible with those used in bzip. To open .bz archives, you must use bzip, and to open .bz2 archives you must use bzip2. Although bzip2 sometimes yields slightly larger output, it is faster, more reliable, maintained, much more widely used and is believed to be patent-free. Julian Seward, the author of bzip, gives this warning: This program may or may not infringe certain US patents pertaining to arithmetic coding and to the block-sorting transformation itself. Opinions differ as to the precise legal status of some of the algorithms used. Nevertheless, you should be aware that commercial use of this program could render you liable to unfriendly legal action.

Take file, compress each block with 1 of 256 algorithms (including no compression) and use algorithm on a per block basis.
