Free implementation manager software for linux

My cOLLection manager is a manager program for your collections. My cOLLection manager is a fast and easy to use frontend for gdbm with an ncurses interface.

The program was originally designed to organize a large music CD collection, but it is has no restrictions on the entry of any other large range of items. Its main goal is flexibillity.

Fast MD5 Implementation in Java is a heavily optimized implementation of the MD5 hashing algorithm written in Java.
Fast MD5 Implementation in Java includes an optional native method for even greater speed improvements.
How Fast Is It?
Short answer:Much faster than any other Java implementation that I have tested and (surprisingly) even faster than the native, non-Java MD5 implementation on some systems.
Long answer:First of all, it is important to note that the term "fast" is used here in relative terms. The implementation of the MD5 message digest algorithm available on this page is written in Java and is fast compared with other implementations written in Java, both because it is heavily optimized by itself and because there is an optional native method that makes it even faster when the platform supports it. How it compares to a sensible implementation written in a language, such as C, that is compiled directly to machine code, is heavily dependent upon how good of a job the JIT compiler in your JVM does in compiling the code or whether you are able to use the optional native method.
Enhancements:
- Martin West contributed a bug fix and some code refactoring to make all targets work out of the box in the Ant build file. Previously, the "dist" target did not work if the "docs" directory was not present.

M3U-Playlist Manager is an administration of loose m3u-playlists in tree structure. Simple mouse-click to add or remove a song from playlist with currently running Song in the Player.

And other interesting functions. Supporting only XMMS at the moment.

My File Manager is a small and lightweight file manager. It was developed to provide a small and fast file manager, which has only a few dependencies from other packages, but including some interestings things like mount partitions, minimalistic burning capability and mass renaming files. MFM use FLTK graphics toolkit.
Main features:
- Selectable shown fields (permissions, users, groups, date and size)
- Various sort options
- Rename group of files
- Change attributes of group of files
- Compress files
- Burn CD/DVD
- Find files by name or by content
- Mount/umount partitions

Suffix tree implementation library is a C library, an implementation of the suffix trees algorithm to store/retrieve key/data pairs.
The main advantages are a linear indexing time, little memory usage, and very fast retrieving.
It has been developped on FreeBSD/gcc but should be fairly portable.
The source code "testsfx.c" show an example of how to use the library both for inserting, retrieving, and deleting data. There arent many functions and comments should be enough to give you an idea of how to use the library. (read the header of the source file)
You should edit sfxdisk.h to suit your needs: you can change the alphabet size and the offset type. It should be OK to use "long long" 64 bits ints instead of long, in fact I tested it succesfully but havent gone to the point of filling more than 2 GB of data (needless to say you need a 64 bits filesystem).
Two "tools" come with the library (new with version 1.2): dumpsfx and loadsfx. dumpsfx is used to dump the database: dumpsfx [-s separator] if you want to output the result as readable text or dumpsfx < file.sfx > -h to output it for reloading with loadsfx.
dumpsfx outputs on stdout and loadsfx reads from stdin. loadsfx < suffix tree file to create > < dumped_file
Enhancements:
- removed an useless offset incrementation in STwritenode

Pure FTP Manager allows a user to access multiple FTP chrooted sites with a single username and password. The program uses pure-ftpd and PostgreSQL for FTP and authentication. A site is chosen by adding @sitename to the users login

HFM is a font manager for Unix systems. With it you can control the avaliability of fonts in all of the supported applications from a central place. Currently included are modules to support:

* X-Window
* Ghostscript
* TeX

A PostScript module handles PS Fonts. Other fonts remain untouched by this program.
