The Electronic Frontier Foundation is asking for your help to fight a patent troll who wants to kill podcasting. Personal Audio claims to have a patent on key podcasting technologies, and has been legally threatening many podcasters, including Adam Carolla and HowStuffWorks. Though the EFF has already raised over $60,000 as of this writing, beating its $30,000 goal in under 10 hours, legal fees can get expensive, and they need all the help they can get. So if you love podcasting, or just hate patent trolls, consider supporting their cause!follow link
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.
