AirPort 3.1 Supports Third Party 802.11g PC Cards -- Owners of pre-AirPort Extreme PowerBooks with PC Card slots can now connect to higher-speed AirPort Extreme networks using third-party 802.11g cards. It turns out that Apple's recent AirPort 3.1 update also provides support for PC Cards that use the same Broadcom chip set that Apple uses for internal AirPort Extreme cards. So, if you've been lamenting the poor signal strength of your Titanium PowerBook G4, you can improve signal strength and jump up to 802.11g's faster throughput with a third party card. Both Asante and Buffalo Technologies claim their 802.11g cards work with Mac OS X and the AirPort 3.1 update; other manufacturers using Broadcom's chip set are likely compatible as well. Buffalo Technology's card costs about $60 and is available now; the Asante card costs $100 and should be available this month. [ACE]
Extract Directly from Time Machine
Normally you use Time Machine to restore lost data in a file like this: within the Time Machine interface, you go back to the time the file was not yet messed up, and you restore it to replace the file you have now.
You can also elect to keep both, but the restored file takes the name and place of the current one. So, if you have made changes since the backup took place that you would like to keep, they are lost, or you have to mess around a bit to merge changes, rename files, and trash the unwanted one.
As an alternative, you can browse the Time Machine backup volume directly in the Finder like any normal disk, navigate through the chronological backup hierarchy, and find the file which contains the lost content.
Once you've found it, you can open it and the current version of the file side-by-side, and copy information from Time Machine's version of the file into the current one, without losing any content you put in it since the backup was made.
