Most companies buy servers from the likes of Dell, Hewlett-Packard, IBM, or Sun Microsystems. But Google, which has hundreds of thousands of servers and considers running them part of its core expertise, designs and builds its own. Ben Jai, who designed many of Google’s servers, unveiled a modern Google server before the hungry eyes of a technically sophisticated audience.
Google’s big surprise: each server has its own 12-volt battery to supply power if there’s a problem with the main source of electricity. The company also revealed for the first time that since 2005, its data centers have been composed of standard shipping containers–each with 1,160 servers and a power consumption that can reach 250 kilowatts.

My iPhone battery gets hot occasionally so, of course, I googled it. It turns out that, despite Apple’s restrictions on third-party applications that prevent them from running in the background, they aren’t preventing problems from their own applications.
The standard iPhone apps like Safari, Mail, iPod, Youtube, Stocks, etc do not neccessarily close themselves when you hit the Home button. You need to hold the button down for 8-10 seconds while in the application to force it to quit. Umm, okay.
An alternative is to shut down your iPhone a few times a week. (Hold down the power button till you get a screen asking if you want to power down.)
Heat really reduces battery life so this is definitely worth keeping an eye on and powering down whenever it starts overheating.
