Alasdair Allan is a Scientist, Author, Hacker and Tinkerer, who is currently thinking about trying to fix the Internet of Things, which he thinks is broken.

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. He recently 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 contributor to MAKE magazine, and 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 the most distant object yet discovered, a gamma-ray burster at a redshift of 8.2.

3D printing from your fingertips

February 21 2013

The 3Doodler is a 3D printer, but it’s a pen. This takes 3D printing and turns it on its head … In fact the 3Doodler rejects quite a lot of what most people would consider necessary for it to be … read more

The inevitability of smart dust

January 08 2013

I’ve put forward my opinion that desktop computing is dead on more than one occasion, and been soundly put in my place as a result almost every time. “Of course desktop computing isn’t dead — look at the analogy you’re drawing … read more

Mining the astronomical literature

August 15 2012

There is a huge debate right now about making academic literature freely accessible and moving toward open access. But what would be possible if people stopped talking about it and just dug in and got on with it? NASA’s Astrophysics … read more

They promised us flying cars

August 03 2012

We may be living in the future, but it hasn’t entirely worked out how we were promised. I remember the predictions clearly: the 21st century was supposed to be full of self-driving cars, personal communicators, replicators and private space ships. … read more

The next, next big thing

May 19 2011

Those evangelizing the revolutionary qualities of "the next big thing" (whatever it may be) would do well to revisit past "big things." Truth is, computing goes in cycles. read more

"Overall, this is a fast read and an excellent resource. I can't call it a definitive guide, but it is a great primer on the most useful geolocation features in iOS, with a set of real-world examples."
--Chris Mattmann, Computing Reviews

"A 'must' for any aspiring developer. "
--James A. Cox, The Midwest Book Review: The Bookwatch, The Computer Shelf, June 2012, Volume 7, Number 6

"His pacing is superb, the content detailed, and his examples spot on."
--David Bishop, Bishop Universe

"I cannot stress how brilliant the book Learning iPhone Programming Development by Alasdair Allan is."
--Nick Reffitt, iOS Blog

"I love the way the series is set up. Unlike other video tutorials I've tried, Introduction to iOS Programming is broken into smaller sections. You can start and stop the videos whenever you want, which is great when you have to reference certain aspects of the program or need to backup and watch something again."
--Ricky Tucker, Game Vortex

"So, if you are interested in a crash course into iPhone programming before you dig into it with a more detailed book, this is the one to get. But, it will leave you with the thirst to learn more. Me? I am heading to the O’Reilly catalog to look for an Objective-C book..."
--Richard Slywczak, GRApple, Volume 12, Issue 1, February 2011

" "
--Jerry Pournelle, Chaos Manor, The User's Column, May 2010, Column 358

"The great strength of Allan's book is that it gives you a clear view of the big picture about iPhone development, and fills in most of the essential details. I can hardly imagine a better book to begin the great adventure of developing extraordinary apps."
--Michael Pastore, ePublishers Weekly

"I recommend the book to anyone considering diving into iPhone programming...Learning iPhone Programming is reasonably priced and should remain a solid introductory text for new iPhone developers for some time to come."
--Mike Riley, Dr. Dobb's CodeTalk
