5 Free Collaborative Whiteboard Apps For the iPad
It seems as though the minute the iPad was announced, innumerable light bulbs went off as developers and entrepreneurs everywhere came to the same realization: "We could totally use this device as a digital whiteboard!" Indeed, a search for the word "whiteboard" in the App Store returns a whopping 170 iPad apps. Although the device's 10-inch screen may not compare to a full-sized, physical whiteboard, it can be quite handy to use a virtual whiteboard with team members remotely, and the iPad's form factor suits itself quite well to exactly that. As we mentioned, the App Store is loaded with these kinds of apps, and many of them are quite good.

UPDATE: we're doing a live, updated MOOC of this course at stanford-online July-2014 (not this Coursera version). See here: CS101 teaches the essential ideas of Computer Science for a zero-prior-experience audience. Computers can appear very complicated, but in reality, computers work within just a few, simple patterns. CS101 demystifies and brings those patterns to life, which is useful for anyone using computers today. In CS101, students play and experiment with short bits of "computer code" to bring to life to the power and limitations of computers. Here is another video Nick created for this class.

Reorder everything Put your most obvious argument first. Then put weird off the wall stuff, regardless of importance. Put the strongest argument for your case next. Now list the incidents that will help argue for your point. It's best to keep all this in the form of an outline. Spaces Now print it out. Write Go Back Inside
