Rogue Amoeba has released a downgrade to Airfoil Speakers Touch, the app that enabled an iOS device to act as an AirPlay receiver. The downgrade was necessary because Apple pulled the app a few weeks ago, and the only way Rogue Amoeba could get it back in the App Store was by removing the AirPlay capabilities. Airfoil Speakers Touch can still receive audio from a Mac or a PC (and from an iOS device or iTunes through one of the above), but it can no longer appear as an AirPlay destination for iOS or iTunes directly. In this blog post, it becomes clear that Apple chose to restrict the app purely for unspecified and capricious reasons rather than any rule infractions. follow link
Set Password Activation Time in Snow Leopard
In Snow Leopard, you can now set an amount of time after your Mac goes to sleep or engages the screen saver before it requires a password to log back on. In Leopard, the option was simply to require the password or not. Choose among several increments, between 5 seconds and 4 hours, from System Preferences > Security.
Airfoil Speakers Touch Back in App Store without AirPlay Support
(again I don't know anything about how Rogue Amoeba chose to implement this feature, this is merely a possibility)
Such reverse engineering (I believe) is prohibited by Apple's developer policies; plus it is in fact a violation of the Digital Millennium Copyright Act (DMCA), since the private key that was reverse engineered is a form of encryption.
