The Gettext Commons project provides Java classes for internationalization through GNU gettext and Java ResourceBundles. This makes it possible to use the original text instead of custom property keys, which is less cumbersome and makes programs easier to read. It supports the easy extraction of user visible strings, marks strings as fuzzy when the original text changes to allow translators to check translations, powerful plural handling, and build process integration through Maven.
iList is an intelligent playlist for the KDE media player Noatun. It is intelligent in the sense that songs are selected from a (possibly large) repository of audio files in a smart manner. Think of it as your personal radio station that plays your favourite songs all day long. iList supports implicit song ranking, incremental search, a song history, independent queueing, multiple collections, and fast access to large repositories with auto detection of new files.
