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.

Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
