Aorta is a load-balancing clustered P2P application. It executes Tasklets (which have the ability to split themselves into sub tasks that can be executed in pararell). A typical cluster contains of a LAN with 1-256 computers, each one running aorta. A Tasklet can be of any type ranging from encoding MP3s, Genomic DNA Alignment, or simply to rendering Web pages for high speed/heavily loaded Web sites. You can make functions calls to C/C++, applications like Matlab, etc.
OAF is the Object Activation Framework for GNOME. It has a similar purpose to gnorba, the GNOME 1.x CORBA activation library, and will replace it for GNOME 2.0. It allows you to do much more powerful activation queries than gnorba. Each server is described by an XML file that defines its attributes. When querying or activating, one may specify complex requirements using the OAF query language.
COID is an object-oriented networking library with a tool that automatically generates a lightweight communication layer directly from a C++ class declaration. The coidgen tool automatically extracts designated classes and methods from specified header files and generates a corresponding client class and host dispatcher. The server library manages networked and local connections and provides various services to running objects. The communication layer establishes either remote connection through TCP or direct (vtable) connection between the client and the server (if they reside in the same process).
CarrierWave provides a set of facilities that automate and extend the EJB Value Object (or Data Transfer Object) pattern into supporting arbitrary value graphs. Specifically, CarrierWave provides a code generator that creates typed value objects from the source code of corresponding business objects, a client interface supporting the selection, modification, deletion, and invocation of business objects, and near-transparent business object persistence through various object persistence applications and interfaces like JDO.
DataManager is a library that provides a shared memory pool to allocate buffers from. It includes the necessary things to build servers which regulary produce data and provide them via ringbuffers to clients. It includes the common framework to have locking and various access methods. The use generally boils down to simple get()s and put()s. This project is no longer under active development.
Glib Binding properties is a system that allows developers to bind properties of GLib and GTK+ objects (Ada95 bindings are also available). This makes it possible to synchronize the properties of several objects, so that when one property changes the properties bound with it automatically change accordingly. This often eliminates the need to write callbacks watching for changes of properties. It supports one-way and mutual bindings and bindings with transformation functions.
Ice is a modern alternative to object middleware such as CORBA or COM/DCOM/COM+. It is easy to learn, yet provides a powerful network infrastructure for demanding technical applications. It features an object-oriented specification language, easy to use C++ and Java mappings, a highly efficient protocol (including protocol compression), asynchronous method invocation and dispatch, dynamic transport plug-ins, TCP/IP and UDP/IP support, SSL-based security, a firewall solution, and much more.
JacORB is a CORBA 2.0 implementation written in Java. It contains an IDL compiler, a name service with graphical management interface, an event and notification service implementation, and a transaction service. DII, DSI, DynAny, native IIOP (1.2), Interceptors, OBV, AMI, and ETF are supported. Tools for applets are included. The language mapping complies with rev. 2.3 of the Java language.
