How To: No-Stress Thanksgiving Desserts That Don't Require an Oven

Oven space is scarce on that fated fourth Thursday of November. Even if you can find a spare space for pumpkin pie on the bottom shelf, you risk turkey drippings overflowing from above and ruining your beautiful dessert — not to mention a burnt crust from different temperature requirements. The bottom line is: oven real estate is valuable, and it's tough to multitask cooking for Thanksgiving when every dish requires baking or roasting.

How To: Jailbreak iOS 8.0-8.1.1 on Your iPad, iPhone, or iPod Touch (& Install Cydia)

The release of iOS version 8.1.1 brought some much needed bug fixes to Apple's mobile operating system, but with it came a patch for Pangu's jailbreak method, which worked on iOS 8.0 to iOS 8.1 using a Mac or Windows computer. Luckily, it didn't take very long for a new team of developers to come up with a method for jailbreaking iOS 8.1.1 devices, and much like its predecessor, the process is a cinch.
