From The New York Times: Leandre Nsabi, a senior at Rainier Beach High School here, received some bluntly practical advice from an instructor recently. “My teacher said there’s a lot of money to be made in computer science,” Leandre said. “It could be really helpful in the future.” That teacher, Steven Edouard, knows a few things about the subject. When he is not volunteering as a computer science instructor four days a week, Mr. Edouard works at Microsoft. He is one of 110 engineers from high-tech companies who are part of a Microsoft program aimed at getting high school students hooked on computer science. In doing so, Microsoft is taking an unusual approach to tackling a shortage of computer science graduates — one of the most serious issues facing the technology industry, and a broader challenge for the nation’s economy.
