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.

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

VXL (the Vision-something-Libraries) is a collection of C++ libraries designed for computer vision research and implementation. The project was created from TargetJr and the IUE with the aim of making a light, fast and consistent system. VXL is written in ANSI/ISO C++ and is designed to be portable over many platforms.

The core libraries in VXL are:

vnl (numerics): Numerical containers and algorithms. e.g. matrices, vectors, decompositions, optimisers.
vil (imaging): Loading, saving and manipulating images in many common file formats, including very large images.
vgl (geometry): Geometry for points, curves and other elementary objects in 1, 2 or 3 dimensions.
vsl (streaming I/O), vbl (basic templates), vul (utilities): Miscellaneous platform-independent functionality.

As well as the core libraries, there are libraries covering numerical algorithms, image processing, co-ordinate systems, camera geometry, stereo, video manipulation, structure recovery from motion, probability modelling, GUI design, classification, robust estimation, feature tracking, topology, structure manipulation, 3d imaging, and much more.

Each core library is lightweight, and can be used without reference to the other core libraries. Similarly, the non-core libraries dont depend on more than absolutely necessary, so you can compile and link just the libraries you really need.

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.

Mono is a comprehensive open source development platform based on the .NET framework that allows developers to build Linux and cross-platform applications with unprecedented productivity. Monos .NET implementation is based on the ECMA standards for C# and the Common Language Infrastructure.

Sponsored by Novell the Mono project has an active and enthusiastic contributing community. Mono includes both developer tools and the infrastructure needed to run .NET client and server applications.

Mono includes a compiler for the C# language, an ECMA-compatible runtime engine (the Common Language Runtime, or CLR),and class libraries. The libraries include Microsoft .NET compatibility libraries (including ADO.NET, System.Windows.Forms and ASP.NET), Monos own and third party class libraries.Gtk#, a set of .NET bindings for the gtk+ toolkit and assorted GNOME libraries can be found in the later.

This library allows you to build fully native Gnome application using Mono and includes support for user interfaces built with the Glade interface builder. Furthermore, Monos runtime can be embedded into applications for simplified packaging and shipping. In addition, the Mono project offers an IDE, debugger, and documentation browser.

The OpenSCADA project aims to create a full-featured and state-of-the-art SCADA (Supervisory Control and Data Acquisition) system to be used in industrial and civil engineering applications to control distributed systems from a master location.
The OpenSCADA project was started in order to create a common standard for SCADA applications. This includes specifications, interfaces and reference implementations.
Enhancements:
- This release has many new features and enhancements to existing functionality.
- The interfaces and the reference implementation were cleaned up a little bit.
- The new upstream version of Utgard was added.
