Romer notes that business keeps evolving as new companies introduce new rule sets. The good ideas are copied, and workers migrate from failing companies to the new and old ones where the new rules are working well. The same goes for countries. Starting about 1970, China took some of the effective rules of Hong Kong (which was managed from afar by England) and set up four special economic zones along the coast operating as imitation Hong Kongs. They worked so well that China rolled out the scheme for the whole country, and its Gross Domestic Product took off. “Hong Kong was the most successful economic development program in history.
As newsgathering continues to evolve, new ways of keeping track of current events are developing. Dave Winer joins Phil and Scott to discuss how Twitter and other social networking tools are changing the way that people read and react to the news. He talks about how he followed prior major news stories and why he now has started using social networking tools as a better way.
He then discusses his work with Twitter stats and reviews what can be learned from how Twitter works. He also reviews the possible future of these tools and assesses some of the ways that information is compiled and distributed and what might be different as time goes on.
This scheme produces a sampled sine waveform with 12 samples per cycle. In addition to the desired frequency component, f0, this waveform contains higher-frequency components at (12k+1)f0 and (12k−1)f0, k=1,2,3, and so forth. The lowpass filter comprising IC2B, R7, R8, C3, and C4 easily filters out these undesired components of smaller amplitude. Listing 1 is the assembly-program code that implements the Bell 202 FSK standard. When the control input Data In is high, the output frequency is 1200 Hz; when the control is low, the output frequency is 2200 Hz. The transition from one frequency to the other occurs in a manner that retains phase continuity.
