New HRI Podcast Episode Available: The Case For Rude Robots
I worked with Merel on a new HRI Podcast Episode: The Case For Rude Robots. It is surprising how hard it is for a robot to understand politeness.
Swim Training Patterns books travel around the world
Swimming is much more fun in a community. We share a passion for the sport and I would like to give others the opportunity to enjoy my latest book, Swim Training Patterns. I sent the first two hardcover books I received on their way around the planet. One will travel predominantly westwards and the other eastwards.

The books can only travel by being given from person to person. It should not be send by mail or courier. Given that we are all only six degrees apart, it should not take long for the books to return to Christchurch. Both books contain a tracker, so I can roughly know where they are. Right now, both books are still in Christchurch, but I hope that this will change soon.

If you receive the book, please sign the log and enjoy the book. Once you are done then please simply give it to the next person. This is not a race, so don’t worry if it takes a long time for the book to move forward. If you want to, please send me a photo of the book from where you are.
