David Heineimeier Hansson, the creator of Ruby on Rails and partner at 37signals in Chicago, says that planning is guessing, and for a start-up, the focus must be on today and not on tomorrow. He argues that constraints–fiscal, temporal, or otherwise–drive innovation and effective problem-solving. The most important thing, Hansson believes, is to make a dent in the universe with your company. This clip was taken from Stanford University’s Entrepreneurship Corner

Even Mashable’s Ben Par recently shared PhotoSketch:

PhotoSketch is an “Internet Image Montage” project from five Chinese Computer Science and Technology students at Tsinghua University and the National University of Singapore. The basic premise, works like this:

Step 1. Draw the outlines of the figures you want in your picture – anything from seagulls to a Mercedes, whatever tickles your fancy,

Step 2. Add labels for each of the items, as well as for the background.

Step 3. PhotoSketch will then find real-life images to match your doodles and put them together in a Photoshopped image that will make your jaw drop.

Yes, this thing has such great image recognition technology that it can determine which dog fits best in your canine doodle. Their demo video unveils the true power of PhotoSketch:
