Official Motorola Library -- In TidBITS-322 we mentioned a PowerPC math library compiled from Motorola's PowerPC SDK. The library was later withdrawn due to licensing concerns and Motorola's intent to release their own version. Though it's a few weeks late, Motorola has indeed released LibMoto, which improves the performance of some floating point math functions on Power Macs. The shared library is available for free (a developers version is also available), although Motorola asks users to register online to download the library. If you don't do extensive number-crunching or graphics work on your Power Mac, you probably won't significant benefit from this library, but some users could see worthwhile performance improvements. I've seen unconfirmed reports of problems using LibMoto with the GeoPort Express Modem and some fax software (surprise!), so be sure to take normal precautions before installing this (or any) system software.

Arrange Icons on the iPhone/iPod touch Home Screens
Unhappy with the arrangement of your icons? You can move them around as follows: First, hold down on any Home screen icon until all the icons wiggle. Now, drag the icons to their desired locations (drag left or right to get to other screens). Finally, press the physical Home button on your device. (Unlike earlier releases, iPhone Software 2.1 doesn't move just-updated apps to the end of your Home screens, so your icons should be more stationary once you've installed the update.)
Remember that you can replace Apple's default icons in the four persistent spots at the bottom of the screen with your four most-used apps!
