We have grown accustomed to slogans like "computing is bits, not atoms"---suggesting that bits are not physical and the properties of the physical world are less and less important for understanding computation.</p> Sun, 01 Jan 20120423 00:00:00 GMT Peter J. Denning 2188285 http://ubiquity.acm.org/article.cfm?id=2160599 <p>As computing technologists, we tend to think of innovations in terms of new products or services supported by, or made of, computing technologies. But there are other types of innovation besides products. There are process innovations, such as McDonald's method of making hamburgers fast; social innovations, such as Mothers Against Drunk Driving; and business model innovations, such as Starbucks replacing a coffee shop with an Internet cafe. In all these categories, we tend to think of innovations as new ways of doing things that positively impact many people.</p> Wed, 01 Jan 20120319 00:00:00 GMT Peter J.
