This is about all new technologies. Really for geeks. With source code, with new tools.

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...

Operating Systems for IoT Embedded Systems

This post is an excerpt of the Chapter 4 of “Getting Started with Embedded Systems” in Building the Web of Things, a Manning book by Dominique Guinard and Vlad Trifa. There are two broad categories of physical objects in the Web of Things: tagged objects and connected objects. The first category comprises various tagging technologies that are attached to a product, such as barcodes, QR codes, NFC or RFID tags, IR/AR and so on. In this case, objects are not directly connected to the web but only passively, because there’s a need for another device or application to interact with...

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...

Influencer Series event at USVP

Hi all, we have a short notice but great opportunity for our Californian followers: an invitation to participate to the next Influencer Series. A high profile evening that will be focused on “Unearthing Software & Service Winners in IoT”. These series are high end networking events, capped at 60 leaders chosen by a hosting committee, and hosted at a VC fund office. The event will be the night of Tuesday, September 13 (specific location will be disclosed if an invite is extended) in Menlo Park from 5:30 PM to 9:00 PM. Because these invites are invite-only and capped, a screening...

Supporting ThingMonk 2016 & IoT Diversity Program

In the early days of the IoT there were a handful of conferences you had to attend every year. Most of these early birds are still in play such as Ubicomp & Pervasive, ACM IoT, RFID Journal Live, O’Reilly Solid or smaller ones such as the very fine Sketching in Hardware or our very own WoT Workshop (edition 2016 taking place real soon!). Things have changed however, with the IoT developing at light speed, conferences and events started to mushroom. There isn’t a city that isn’t organizing it’s dozen of IoT events every month. This is all a bit overwhelming...

Building the Web of Things Book is Out!

December 1oth, 2014 Vlad and I signed a contract with Manning Publications for a book on the Web of Things, a year and 8 month later, we are thrilled to announce that Building the Web of Things is out! We learned the hard way that writing a book is not as trivial as it seems. “Oh, we’ll just refresh our PhD theses and we’re done in a few weeks” has gradually turned into “OK, well, I guess we’ll have to write these chapters from scratch over the next few months. What about the source code? Which source code? Let’s just...

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...

6th International Workshop on the Web of Things: WoT 2015

After a successful 5 years anniversary in 2014 it is our pleasure to announce that the International Web of Things workshop (#wot2015) will take place this year again, submissions are now open so hurry up, craft your best WoT papers and submit them. As usual, the WoT Workshop will take place collocated with the IEEE IoT conference, one of the first and most successful IoT conference out there: CALL FOR PAPERS – Sixth International Workshop on the Web of Things (WoT 2015) in conjunction with IoT 2015, Seoul, South Korea, October 26-28, 2015. http://www.webofthings.org/wot/2015 * Workshop Abstract Continuing the successful Web of Things...

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...
