Why should professors care that VLC is back? Because it’s awesome for playing back video files on an iOS device – making it invaluable if you teach by projecting your device using a cable or by AirPlay to an Apple TV or AirPlay server. The best part? Simply connect your device to your computer, go into iTunes and choose the device, and then navigate to VLC in the apps list. You can then add/remove video files directly, making it a breeze to load up several clips for one lecture, then remove them and load up several more for another lecture. I prefer this over the built-in tools (i.e. Videos, Music, Podcasts app) since I’ve found all of those to have sync issues at times. Plus it’s nice to isloate your teaching content from your personal content.
