Oh HTML5 WebSockets, Push Data to my Mobile!

At last a slightly geeky post ūüėČ ! A few days ago I was at Google Zurich (GTUG) to present a more technical remix of a talk I originally gave at Jazoon 2011. In a nutshell, the talk was about how HTML5 WebSockets would soon be ready for pushing data to mobile phones in a standard way (and possibly soon to/from any embedded device?). In a Web of Things context, we used this at the MIT Auto-ID labs to push data “directly” from RFID readers to Android or iOS mobile phones within a few lines of Javascript code (for the...


What is the Web of Things?

Note: this article was first published in the IoT Technica Curiosa magazine. The Internet of Things – IoT for short – is here to stay and to change our world for the better. This grand vision depicts a world where people, buildings, and physical objects are connected to a single and common network. Bottles of soda, lighting systems, cars and everything in between can provide services and exchange data with each other. You might have noticed that the Internet of Things feels very much like an Intranet of Things: to interact with 10 different devices from your phone, you have...

Node.js, GPIO and the Raspberry Pi

This post is an excerpt of the Chapter 4 “Getting Started with Embedded Systems” in Building the Web of Things, a Manning book by Dominique Guinard and Vlad Trifa. In a previous post we talked about the increasing importance of Node.js for embedded systems in the IoT but we didn’t have a concrete look at what using Node.js on an embedded device looked like. In this post we’ll look at what it means for the Raspberry Pi. Installing Node.js on a Raspberry Pi The first step is to install Node on your Pi. The latest versions of Raspbian (the Pi...


Web of Things vs Internet of Things: 1/2

In this series of articles, excerpted from the first few chapters of our shiny new book: Building the Web of Things, we wanted to clarify what is the difference between the Internet of Things and the Web of Things, should there be one. Let’s put it straight first: the pun was intended! We always used the term Web of Things and opposed it to the Internet of Things to provoke a little but for a good cause: raising the awareness on the need for protocols to converge at the application layer. In the first part (a cross-post of our DZONE...


What’s in HTTP/2 for the Internet of Things? 1/2

If you followed this blog you probably know that the motto of the Web of Things community is to re-use Web protocols to build a truly interoperable Application Layer for the Internet of Things. One of the key protocols we are talking about is HTTP currently massively deployed on the Web in its 1.1 version. HTTP/1.1 is a great protocol when used correctly to build Web Services as illustrated in this book! However, it dates back from 1999. Remember this time? Back then we were using Windows 95, wired phones to call each other and the IoT term had just...


The Web of Things has a Book!

In 2007, Vlad and I were working at SAP Research on a European project called “SOCRADES” (disclaimer: vintage video content inside, remember this was 2007 :)). The goal of that project was to create a service layer for the Internet of Things. In short it was all about integrating real-world Things to applications so that the media gap between, say, real-world sensors and ERP applications would be drastically reduced. The idea was sound, really sound. The approach we used much less… We started looking at WS-* (aka big Web Services, or SOAP WS) services and pushing them down to devices....


First WoT W3C Interest Group Face to Face Meeting

Note: although this is a summary of the ideas and discussions I was involved in at the WoT W3C IG meeting these are my views and they may not necessarily reflect the views of the W3C WoT IG.   A couple of weeks ago we had the chance to participate to the first face to face meeting of the W3C WoT (Web of Things) Interest Group (IG).¬†We were reporting a little while back about the foundation of this group which was officially kicked off recently with a first face 2 face meeting that took place in Munich. This group is...


Thread Group: Q & A

After a recent comment request from the press on the news that The Thread Group have announced a new protocol for connected devices in the home, I thought this would be a good opportunity to share some of the insights we pulled together for the piece. The format of the Press comment was a simple Q & A, and went as followed:


ebay’s IoT Collections: The Mashable Web of Things Home

Welcome to our final blog from the¬†eBay Internet of Things collections¬†series! In our penultimate post in this series, we were showing you how to implement a low-tech version of home automation using NFC and the EVRYTHNG engine. This time we’ll look at the bleeding-edge version of our connected home! A home where appliances can be piped together easily to create a dynamically reconfigurable home. Just like you can use IFTTT¬†or Yahoo Pipes¬†to create smart workflows for your data (e.g. if I tweet this, post this to my LinkedIn profile and update this Google Spreadsheet) you should be able to configure...
