Wikitty is a key/value storage and search system. A Java object or a relational table is frozen when writing code or creating a database. To make them evolve, you have to go back into the code, write a migration process, etc. It is also hard to maintain coherent code when you want to develop the same application for similar needs with only small differences. Between the common code and the specific code, it can easily become a real burden. Wikitty tries to answer those problems, bringing a technical solution which is easy to put into place and to use.
The J2DGAMEFRAMEWORK provides the necessary classes to implement a simple 2D game in a window enviroment using Java Swing libraries. This framework also provides a Sprite Collision Manager and a simple GUI template. By using this framework, the developers only concern is how to implement classes, and not the 2D World, the collisions, etc. It uses the Observer Design Pattern. It has double-buffered rendering, simple use of collisions, and user-transparent multi-threading for collision classes. You can move sprites like a vector with speed and angle, and simply save and load your game.
Java distributed framework is a framework for distributed grid and / or volunteer computing. It's divided into a server and client library. You can create new or implement it into existing applications in no time; you don't need knowledge about network connections, sockets, etc. The Framework does almost everything automatically. It provides secure automatic client <-> server communications, unique IDs, automatic resending of jobs to new clients if needed, user stats, and much more. The client framework supports the detection of the computer's user state (idling, away, online, etc.). It also offers many other useful features and helpers for developing a distributed client application.
