IN CONTROL Offer -- I guess Attain liked Matt Neuburg's review of IN CONTROL in the last issue since they have made it easier for TidBITS readers to check out the program and expand their wardrobes at the same time. If you order via email to <firstname.lastname@example.org> you will receive IN CONTROL 2.0 and an IN CONTROL t-shirt for $75, which includes shipping within the U.S. That's about $10 cheaper than mail order, and you get the t-shirt. I didn't receive further details in time, but I assume you would have to include your shipping address, telephone number, and credit card type, number, and expiration date.
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.
