Unless you're ingesting insane amounts of caffeine, you're probably not staying awake around the clock to listen to your favorite podcasts the second they're put online. Juice, an open source podcast receiver, lets you snag your favorite audio programs from the Internet and store them on your computer until you're ready to listen.

Juice is a cross-platform app that runs on Linux, Mac, and Windows. Once installed, simply point it to the URL of your favorite podcasts and decide whether you want it to download them automatically or manually.
