iPhone Programming courses

I have stumbled across a quite nice introductory course on iphone programming on iTunesU. Its from the university of Utah and they got a nice video podcast along with slides and some sample code. Definitely a good way to start developing for the iPhone.



Another course can be found at


However, I havent had time to check that one out yet.

Made some changes to Audiobook Maker

If you are an audiobook fan like I am, then you probably often wondered how to create nice audiobooks with chapters and all. I am such a guy and have been using Audiobook Maker for a while since its open source and free. However, it has a few shortcomings that made me want some modifications. Unfortunately, it seems that the author has stopped maintaining the app and thus I went to work and made the changes I needed.


  • added warning when file > 350MB or > 14h since usually then ChapterTool bombs out
  • added support to process m4a and mp4 files (however, no bitrate transcoding yet)
  • fixed issues with files containing special characters like spaces, quotes, …

I will ask the developer to integrate the changes, if not, I will post the sources here.

A big thanks to the guys at




which tools I have used in order to process mp4 files.
