from Lifehacker:
The No Thick Manuals wiki details how to learn a language efficiently using two free, open source applications. The first is jVLT (java Vocabulary Learning Tool), a completely cross platform flash card application. The second is StarDict, a Windows/Linux-only dictionary that provides an impressive array of features and dictionaries. Granted, most of us would require some textbooks and/or audio supplements, but anyone learning a language needs a good dictionary and some flash cards, and these free desktop applications sound a lot simpler than making flash cards by hand and manually looking up words in your dictionary.
