Bad news for Microsoft — North Korea doesn’t even want to copy Windows anymore. The latest version of Red Star OS, the nation’s official Linux distribution, now bears a striking resemblance to Mac OS X, as opposed to earlier versions that mimicked the Windows interface. Of course, no North Korean operating system would be complete without propaganda, such as setting the year to 103 — the number of years since Kim Il-sung, the founder of North Korea, was born. follow link
Avoid Long Hierarchical Menus
If you right-click (or Control-click) on some item, such as a file in the Finder, and one of the sub-menus has many options (Open With is a frequent culprit), it may take several seconds to open, even on a fast machine, which is annoying if you did not actually want that sub-menu.
The trick is to not pull the cursor through the menu, but in a curve around it, so the cursor does not touch any menu items until lower on the list where you wanted to go.
