OpenJUMP is a community driven fork of JUMP the "Java Unified Mapping Platform" GIS software. The original JUMP was developed by Vivid Solutions, released under GPL2 in 2003 and discontinued in 2006. During 2004 already some enthusiastic developers joined together to enhance further the features of JUMP. They launched an independent development branch called OpenJUMP. The name gives credit to the original JUMP development, and at the same time describes the objectives of this project to be fully open to anyone wanting to contribute. These days OpenJUMP is developed and maintained by (some few) volunteers around the globe. If you need functionality or even better want to contribute you are very welcome to contact us at our mailing list.

Flashcards application with Spaced Repetition method
Fresh Memory is an education application for studying languages with Spaced Repetition method and flashcards. Its primary purpose is to study and repeat vocabulary of foreign languages. But other disciplines can be studied as well: history, geography, medicine, mathematics. The study material is stored as collections of flashcards. The flashcards may have several fields, and the user controls what combination of fields to learn. The flash cards can have formatted text and images. The look of flashcards and studying parameters are can be flexibly configured.
