Smarter Parental Controls

If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.

To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.

Just a couple of quick multimedia bits for you this week — Adam talking about security on the Tech Night Owl podcast and a video about how Pixar almost lost “Toy Story 2” to a bad backup.

Adam Discusses Mac Security on the Tech Night Owl Live -- Security is one of those topics you wish would just disappear — because then no one would need to think about it. But until that happens, we’ll end up trying to explain just what’s going on and how you can protect yourself, as happens in this discussion Adam has with Tech Night Owl host Gene Steinberg.

Bad Backup Nearly Obliterated “Toy Story 2” -- We frequently harp on not only keeping data backups, but also on ensuring that your backups are good. (That’s why Adam Engst has designated every Friday the 13th as International Verify Your Backups Day.) It’s inconvenient to lose some recent files or email messages, but a good backup policy is even more essential for larger projects — like an entire movie. Two people involved explain how Pixar nearly lost a year’s worth of work on the movie “Toy Story 2” after someone accidentally entered rm * (the Unix command to delete all files) and the company discovered their backup had been compromised. The film’s salvation came from an unexpected source.
