Apple has announced that the company’s annual Worldwide Developers Conference will take place from 11 June 2012 to 15 June 2012 in San Francisco. Tickets cost $1,599 and sold out within the first two hours (much to the consternation of West Coast developers who woke up to discover they couldn’t attend).follow link
Move the Dock Quickly
You may find it convenient to move the position of the Dock when working in certain programs or with certain files. Rather than choosing a different position from the Dock preferences pane or using a submenu in the Apple menu's Dock submenu, you can move your Dock to a different screen edge merely by Shift-dragging the separator that divides the application and document sections.
