Why writing a book?

§  Encourage people to build Web connected Things -  Interoperability, openness!

§  Provide an end-to-end methodology to build IoT products -  For universities -  For makers -  For innovators -  For developers -  => Just the “right amount of tech!”

§  Report on our experience @W3C WoT and talk about future standards §  On our “bucket list”!

Chapter 3: Node.js for Embedded Devices?

§  Before: −  C rules −  Windows based IDEs, 1 per platform −  Small community, highly specialized −  Very resource constrained devices −  Integration via specialized SDKs

§  After −  Node.js is taking over! −  Larger community, more reach, more

innovation −  Huge ecosystem of libraries −  Integration via the Internet and the

Web

Problem 2. Am I really talking to the

heater? Or to a fake device trying to steal my

passwords?

Problem 3. Is it really Lena who sent me

this request? If so, is she allowed to change my

temperature?

Yo Heater!Set Temperature to 10° C

Lena's Mobile AppHeater Unit

Problem 1. Am I sure that no one can see the message I

am sending to the heater?
