The Wall Street Journal reports that IBM is offering a system that delivers open-source business applications to thin clients - computers without hard drives or powerful innards. Like with Google applications, central servers at a company handle the heavy lifting. Cost savings could be $500 to $800 per year, plus a reduction in IT support costs. This has been tried before, but IBM says Microsoft Office alternatives are now good enough to compete.follow link
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.
