Alasdair Allan

Alasdair Allan is a Scientist, Author, Hacker and Tinkerer, and co-founder of a startup working on fixing the Internet of Things. He is the author of a number of books, and from time to time he also stands in front of cameras. You can often find him at conferences talking about interesting things, or deploying sensors to measure them. Last year rolled out a mesh network of five hundred sensors motes covering the entire of Moscone West during Google I/O. He's still recovering. He sporadically writes blog posts about things that interest him, or more frequently provides commentary in 140 characters or less. He is a contributing editor for MAKE magazine, and a contributor to the O'Reilly Radar. A few years ago he caused a privacy scandal by uncovering that your iPhone was recording your location all the time. This caused several class action lawsuits and a U.S. Senate hearing. Several years on, he still isn't sure what to think about that. Alasdair is a former academic. As part of his work he built a distributed peer-to-peer network of telescopes which, acting autonomously, reactively scheduled observations of time-critical events. Notable successes included contributing to the detection of what—at the time—was the most distant object yet discovered.
