Free implementation services software for linux

Open Project Services (OPS) is a project collaboration platform, integrating server components such as e-mail, calendaring, timesheets, documents, knowledge, etc. with standards complient clients. Open Project Services consists of a project server and a set of client extensions.
We are building a project collaboration platform. It consists of a project server that integrates with services needed within a project, e.g. e-mail, calendaring, timesheets, documents, knowledge, etc.
The project server is a Webservices hub based on Java (J2EE). The persistence layer for project information is LDAP. We use OpenLDAP now, but others should also be possible. The e-mail backend makes use of a standard IMAP server. Our reference implementation uses Courier.
We are building extensions/plugins for clients, making them OPS-enabled. We support e.g. Mozilla Thunderbird (XUL) and Squirrelmail (PHP) for e-mail clients. For the calendaring and timesheet components we have a Mozilla Sunbird extension (XUL).
In short: we are building a project collaboration environment on an OSS stack, enriching services with project information, using COTS clients/servers and open standards.
Enhancements:
- This release includes some changes to the underlying LDAP schema to make it possible to disable tasks when they are completed.
- To make use of this new feature, the Web services and the sunbird timesheet client have to be updated.

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.

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

The QDS library allows Qt applications to access features provided in common desktop APIs in a portable way, without requiring dependencies on any desktop platform library.
This is especially useful for applications targeting the Unix desktops, because Qt/X11 is very generic and only provides features it can implement on all sub platforms. All library code is licenced under 2-clause BSD licence.
Service implementations are loaded from plugins which link to the respective desktop libraries. The plugin to use can be specified on the applications commandline, in the QDS configuration file or QDS can try to autodetect the currently running platform.
Enhancements:
- Autodetection to use GNOME plugin in case GNOME_DESKTOP_SESSION_ID is set
- Replaced the primitive example application with a simple but network aware text editor application
- Support for wildcards in mailcap entries

Bellagio is a sample implementation of OpenMAX IL for Linux.
It enables software developers and ISVs to familiarize themselves with the OpenMAX IL API and to develop their own OpenMAX multimedia and streaming media components for mobile devices, including codecs, video I/O, and audio mixers.
Included sample components comply with the OpenMAX base and interoperability profiles and can be tunnelled together.
Main features:
- a shared library with the IL core and a "reference" OpenMAX component
- a number of OpenMAX components which pass Khronos conformance tests
- a set of GStreamer plugins that use the IL API (not available yet)
Enhancements:
New video components:
- ffmpeg based MPEG4/H.264 decoder
- color converter component YUV -> RGB
- video renderer based on devFB
New audio component:
- audio file reader based on ffmpeg audio format
- volume component
Fixed known bugs:
- FFMPEG audio decoder now works on FC6 and other distributions with the latest ffmpeg release (0.4.9-0.35.20070204)
Known pending bugs:
- some ogg streams can not be decoded properly
- the tunneling between file reader, mp3 dec based on ffmpeg - alsa sink ends in a deadlock sometimes.
- This behavior has been detected some times using FC6 and UBUNTU, not with the FC4
Full list of components:
Audio:
- ogg decoder based on libvorbis (stand alone components, and multiple roles component)
- mp3 decoder based on mad decoder
- mp3 decoder based on ffmpeg (multiple roles component)
- volume component
- alsa audio sink
- ffmpeg audio file reader (to be used with mp3 ffmpeg decoder)
Video:
- MPEG4 decoder based on ffmpeg (multiple roles component)
- H.264 decoder based on ffmpeg (multiple roles component)
- Color converter based on ffmpeg
- video renderer based on devFB
- Major additions to the 0.2
- New port classes
The components are:
- multiple formats audio decoder component that supports mp3 and ogg audio formats
- alsa sink component
- all the other components are NOT compatible with the new architecture.
- They have been removed and will be ported to the new architecture in a further delivery

PHP P10 Oper Services project is a small IRCD operator services written in the PHP scripting language.
It supports levels, and it uses a database. It currently supports the IRCU P10+ IRC server and the PostgreSQL database.

Firebird .NET Data Provider is an ADO.NET data provider for Firebird. Firebird .NET Data Provider is written in C# and provides a high-performance native implementation of the Firebird API. It also includes an implementation of the Firebird Services API and Firebird array datatype support.

Firebird is a relational database offering many ANSI SQL standard features that runs on Linux, Windows, and a variety of Unix platforms. Firebird offers excellent concurrency, high performance, and powerful language support for stored procedures and triggers. It has been used in production systems, under a variety of names since 1981.

Firebird is a commercially independent project of C and C++ programmers, technical advisors and supporters developing and enhancing a multi-platform relational database management system based on the source code released by Inprise Corp (now known as Borland Software Corp) on 25 July, 2000 under the InterBase Public License v.1.0

Objective Modula-2 programming language is a hybrid between Smalltalk and Modula-2 based on the object model and runtime of Objective-C.
The design is an example how native Cocoa/GNUstep support can be added to static imperative programming languages without implementing a bridge.
Objective Modula-2s scope encompasses the design of the Objective Modula-2 programming language and the implementation of a compiler to implement it. The initial compiler will generate Objective-C source code.
Enhancements:
- This code is used to verify ideas and concepts which come up in the course of defining the language.
- It is in an early stage, incomplete and subject to frequent changes.
