Anki is a nice spaced repetition system (
Leitner-style flashcard program) with a debian package. If you are interested in
learning the kanji, for example, you might like to check it out.
I'm trying it under debian arm (oabi) but am having problems with floats in the sqlite database, so I'm wondering if the changes to fpe under eabi might make a difference. If anyone tries it out on their eabi system please let me know. Details of the bug can be found
here, but the basic problem is that a deck copied from a debian/i386 system will have wacky random dates when opened on the z.
Thanks!
