Mixxx is software for DJs that provides everything needed to create live mixes. It allows you to beatmatch songs and crossfade them together, like you would with turntables and a mixer. It runs without any extra hardware, and offers a wide range of advanced features including comprehensive MIDI controller and vinyl control support. To obtain the lowest latency and highest responsiveness, it uses hardware video acceleration and takes advantage of multi-core CPUs.
localcast is designed for Mac users who want to be able to resume podcast downloads after an error or unexpected sleep, something that iTunes cannot do by itself. Systems without iTunes can use localcast as an alternative to bashpodder. localcast depends on Mac OS X personal Web sharing and on wget. With localcast, interrupted downloads can be resumed, because wget fetches the podcasts. Podcasts appear fully integrated in iTunes just as if localcast was not in use.
