While an increasing amount of data and computing power is moving into the cloud, this paper by Microsoft Research and researchers at the University of Virginia proposes relocating the servers that host cloud services into residential dwellings, where the heat produced can be used to heat the home during the cold months. Most interesting is the researchers’ calculation that using their “data furnace” concept could result in savings of up to $300 per server per year, in comparison to traditional data centers. Regardless of whether the numbers would bear out in reality, I can say with assurance than a single Mac Pro and two 24-inch monitors makes my office significantly more comfortable in the winter. 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.

Hot servers are sad servers...
Stirling and other heat engines can BE the air conditioning; charge electric vehicles; supply standby power for the building. The best way the government can help is to stand clear out of the way!
