Change the Notification Center Background Pattern in Mac OS X
Tired of seeing that linen wallpaper in the background of Notification Center of OS X? You can change that linen pattern to something else, giving a nice customized appearance to the Notifications panel when you’re checking alerts on the Mac.

We’ll cover three tricks to fix major iOS crashes, the first will attempt to just exit out of the crashing application, the next will forcibly restart the device, and finally for the worst scenarios, we’ll restore iOS as new, though that really should be a last resort that is rarely applicable to most situations.
If you’re a heavy command line user, you’re probably well aware that the arrow keys can be used to flip through previously executed commands and the tab key can complete them. But both of these functions can be significantly improved upon for searching through past command history by adding a few modifications to your .inputrc file.
