Berkeley DB (libdb) is a programmatic toolkit that provides embedded database support for both traditional and client/server applications. It includes b+tree, queue, extended linear hashing, fixed, and variable-length record access methods, transactions, locking, logging, shared memory caching, database recovery, and replication for highly available systems. DB supports C, C++, C#, Java, PHP, and Perl APIs. It supports key-value pair (NoSQL), SQL, and Java Object formatted data. It is available for a wide variety of Unix platforms as well as QNX, Android, Mac OS X, and several varieties of Windows.
Universal Password Manager (UPM) allows you to store usernames, passwords, URLs, etc. in an encrypted database protected by one master password. Its three strongest features are simplicity (it provides a small number of very strong features with no clutter), the ability to run cross-platform, and database sharing. Rather than having many separate databases (home, work, etc.), database sharing allows you store your database at a remote location (password protected HTTP URL, for example) and then have UPM automatically keep your local database in sync with the remote database.
The KaufKauf Shoppingmanager is a Web-based application that allows you to manage your goods at home. It supports barcode scanners for faster management, and it automatically creates shopping lists that can be printed out or downloaded by cellphone. It also watches "best before" dates and informs you via email or SMS when foods reach that date. The complete application is a system that can be accessed from nearly everywhere and offers you the possibility to find out what you really need next from the supermarket.
Janus is a platform designed to deal with the implementation and deployment of holonic and multi-agent systems. It is based on the CRIO organizational metamodel. The concepts of role and organization are supported as first-class entities. Janus provides a comprehensive set of features for developing, running, displaying, and monitoring multi-agent-based applications. The platform also natively manages the concept of recursive agents (holon or agents composed of agents). It can also run threaded and non-threaded agents without using the organizational and holonic API. It provides features equivalent to those of TinyMAS or MadKit.
libnode is a C++ implementation of Node.js. Just like Node.js, libnode provides non-blocking I/O, which enables you to develop scalable Web applications in C++. The memory management of libnode is automatic, based on either shared_ptr or bdw-gc. libnode is good to use on embedded devices because its system resource consumption is lower than Node.js.
