prbeditor is an editor for Java property resource bundle files. The application's intent is to help in the localization (l10n) of those programs that have been internationalized with Java's standard i18n mechanism. In contrast to other similar tools, it shows the keys and values of several languages at the same time in a spreadsheet, giving a global view of the resource files. The tool relies on the application of regular expresions to organize the keys and filter the visibility of the files. It includes a spell checker for several languages, based on word lists which may be downloaded separately.
Biogenesis simulates in a visual fashion the processes involved in the evolution of unicellular organisms in nature. It tries to be a didactic approximation to the ideas of mutation or evolution, and can be enjoyed also as an entertainment. It's intended to serve as a support to show students some basic biological facts. The idea of Biogenesis is taken from Primordial Life, but it's an independent project.
