EO is a templates-based, ANSI-C++ compliant evolutionary computation library. It contains classes for any kind of evolutionary computation (specially genetic algorithms) you might come up to. It is component-based, so that if you don't find the class you need in it, it is very easy to subclass existing abstract or concrete class.
Deva is a programming language that is small, dynamic, and has some similarities to C and Python. It is designed for embedding in C++ applications, and is also suitable for basic programming tasks. It is written to be as simple as possible, but no simpler. Deva is a multi-paradigm language: it is essentially procedural and imperative, but with support for basic functional and object-oriented idioms.
Agnos is a cross-language, cross-platform, lightweight RPC framework with support for passing objects by value or by reference. Agnos is meant to allow programs written in different languages to easily interoperate, by providing the needed bindings (glue-code) and hiding all the details from the programmer. The project essentially serves the same purpose as existing technologies like SOAP, WSDL, CORBA, and others, but takes a minimalistic approach to the issue at hand. Unlike the aforementioned technologies, which tend to require integration with Web servers, using verbose XML-based protocols on top of textual transports (HTTP), often also requiring complex topologies (such as name servers for registering objects, etc.). Agnos is designed to be simple, efficient, and straightforward, allowing for direct communication between two ends using a compact binary protocol.
CLOGS is a library for higher-level operations on top of the OpenCL C++ API. It is designed to integrate with other OpenCL code, including synchronization using OpenCL events. Currently only two operations are supported: radix sorting and exclusive scan. Radix sort supports all the unsigned integral types as keys, and all the built-in scalar and vector types suitable for storage in buffers as values. Scan supports all the integral types. It also supports vector types, which allows limited multi-scan capabilities.
libquickmail is a library intended to give C/C++ developers a quick and easy way to send email from their applications. It supports multiple To/Cc/Bcc recipients and multiple MIME attachments without size limitation. It uses libcurl for SMTP communication, but a light version is also included without the libcurl dependancy. The library can also be used to just create a multipart MIME message body. It also comes with a command line application for sending mail (with optional attachments).
