garith is a game similar in spirit to BSD's "arithmetic" or TuxMath. The game asks you to perform a simple arithmetic operation within a certain time frame. It improves your skills by stressing the operations you get more frequently wrong or that longer to answer. The statistics are saved/restored across games, so that each game is tuned for your current arithmetic abilities.
Web4thejob is a Java framework for rapid development of data-centric Web applications. It is ideal for those who seek a component-based event-driven full-stack Web development framework capable of producing elegant desktop-style Web applications which can automate any business domain. The framework addresses the automation needs of business domains by introducing "joblets". A joblet is the equivalent of an app on a mobile platform. Similarly to mobile apps which can turn a cellular phone to a social meeting point, a game console, or TV set (i.e., the smartphone), joblets can turn Web4thejob into a Web application suitable for any business domain.
