Tests & Fixes for Defective Palm DRAM -- Palm, Inc. has posted testing software for a problem caused by a batch of defective memory modules in Palm IIIc, IIIxe, and Vx handhelds manufactured between October 1999 and May 2000. The problem affects only 8 MB DRAM chips and can cause random data to be written to the handheld's memory. If you own one of these machines, go to the support section of Palm's Web site and enter your machine's serial number to determine if your device falls into the timeline. (Your serial number is on the back of your unit; if it has rubbed off, Palm provides instructions for accessing your serial number via software.) If your unit is potentially affected you'll be able to download the testing application, and a software patch is available to fix affected Palm IIIc and Vx units. (As of this writing, a patch is not yet available for the IIIxe.) The faulty DRAM also made its way into a few other Palm OS devices: Handspring, Inc. has posted a testing application (though it doesn't currently offer a fix) for its Visor line, while the Technology Resource Group (TRG) recommends that owners of TRGPro devices upgrade to its version of Palm OS 3.5.1.

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.
