Alasdair Allan is a Scientist, Author, Hacker and Tinkerer. He is the author of a number of books, and a contributing editor for MAKE magazine. Last year he rolled out a mesh network of five hundred sensor motes which covered Moscone West during Google I/O. Before that he caused a privacy scandal by uncovering that your iPhone was recording your location, which caused several class action lawsuits and a U.S. Senate hearing. Several years on, he still isn't sure what to think about that.
