An anonymous reader writes: Andrew Kelley was a big fan of the Amarok open source music player. But a few years ago, its shortcomings were becoming more annoying and the software's development path no longer matched with the new features he wanted. So he did what any enterprising hacker would do: he started work on a replacement. Three and a half years later, his project, Groove Basin, has evolved into a solid music player, and it's still under active development. Kelley has now posted a write-up of his development process, talking about what problems he encountered, how he solved them, and how he ended up contributing code to libav.
