The LinuxClassLibrary is a growing set of classes which everyone needs every day, that runs on all types of *nix and also on Win32. Currently it is a library that works in the background (non GUI). Current features are character handling, file descriptors (sockets, file, etc.), a database system (like the Perl DBI), an event system, template collection classes (set, heap, hash, etc.), IPC, protocols, plug-ins, and images.
LGI is a lightweight GUI library and application framework. It supports cross-platform widgets, threads, Unicode, a multi-language resource file in XML (with graphical editor), drag and drop, common dialogs, network support with implementations of common protocols, and an HTML control.
Libc-X provides extensions to the standard C library implementing useful and powerful data structures and functions. Its Unix name is libcx. It is not a template layer. It is made entirely with the C standard language, compatible with C++, and portable. All developed structures are designed to be used in stand-alone mode with limited dependencies with other features of Libc-X. For example, you can easily extract the header and the .c source of Hashtable and use it outside Libc-X.
LinCE is a programming environment that is simple, pluggable, multiplatform, and multilanguage. LinCE allows you to create and load Ant projects, compile them, and browse errors line by line. It also allows you to execute PMD on Java projects. PMD is a tool that statically checks Java code, looking for potential problems. LinCE generates configuration GUIs from configuration Java objects. It has Apache Ant scripts for plugin development. LinCE provides technical documentation in Spanish.
MARIE is a new design tool for mobile and autonomous robot applications, designed to facilitate the integration of multiple heterogeneous software elements. It is a flexible tool based on a distributed model, thus allowing the realization of an application using one machine or various networked machines, architectures, and platforms.
MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.
MV3D is a virtual world and multi-player game framework for use with Python. It was designed with scalability in mind and is able to distribute a world across as many servers as needed while dynamically balancing the load. The simulation framework is not specifically slanted towards any one genre of online game or virtual world, and can just as easily be used for a space game as a fantasy setting. Objects on an MV3D server can be simulated using the ODE physics engine for realistic interactions. A single server is able to host thousands of of simulated objects. The client works with both the Ogre3D and Panda3D renderers.
Mergence is a high-performance HL7 integration engine and application platform based on Apache ServiceMix. It was developed to fill the need for an open source, fully transactional health care integration system capable of handling millions of messages per day and thousands of concurrent LLP connections. Message transformation and scripting is done using Groovy.
