David J.C. MacKay, Machine Learning pioneer, dies
I know him from his pioneering work on sustainable energy. Actually working out from physics principles what is possible that can balance supply and demand in an ongoing way.<p>You can read it free online - I like the print copy though! (It's for the UK, but has lots of useful referenced data for anywhere)<p><a href="http://www.withouthotair.com/" rel="nofollow">http://www.withouthotair.com/</a><p>I met him a few times in Cambridge trying to organise a campaign about Climate Change. He was passionate and fun. Sad that I never really delivered for him.<p>Rest well David, combining a scientist's accuracy and detail with a human's care for the world.
