M2M Community at EclipseCon

Day 2 of EclipseCon 2013 and we’ve already been seeing some strong interest in the M2M community and the kinds of projects we have been working on!

The story so far

There were two  M2M events on day one. The first was the M2M tutorial featuring some real hardware (Raspberry Pi and Arduino), using the Koneki Lua Development Tooling to deploy scripts to the embedded Mihini runtime on the Pi to drive and take input from sensors over Modbus. I cheated a little and mixed in a bit of MQTT using the Paho Lua client, to have my kit publishing temperature and light data to a broker instead 🙂 It is early days for Eclipse Mihini, but it was a really slick demo and tutorial, and I’m looking forward to playing with this a lot more.

The evening Birds of a Feather session gave a group of us a couple of open hours to hack around with our Pi and Arduino kits. My own efforts were slightly thwarted by a European soldering iron and a 110V power supply, so I wasn’t able to assemble the add-on board I wanted for my Raspberry Pi, but I’ll get back to that in the future. For those looking to explore their new Raspberry Pis and hardware / GPIO interaction from Java, take a look at the pi4j project.

Building a community

One useful “war story” that was told today was in Benjamin Cabé’s Building the M2M Community talk. The slides will follow, but it was good to hear about the progress of the community and projects involved (yes, ok, I’m a Committer on one of them…) and also to hear about his “Community Manager Toolbox” for tracking and responding to community discussions. I use a very similar set of tools when I engage with the Cloud Foundry and MQTT communities (and others that I’m involved with).

Here’s a summary:

  • Slideshare – monitor who favourites and downloads slides related to your project
  • Twitter – monitor hashtags, engage complainers
  • YouTube – screencasts, demos, build channel to aggregate content
  • StackOverflow – answer questionss (even old ones), find answers that need to be complemented)
  • Github – monitor forks, stars, look for people using your tech (include Gists)
  • Google Alerts
  • IFTTT – e.g. if Eclipse wiki changes get Gtalk notification recipe
  • Google Analytics for your site
  • LinkedIn – monitor groups, post news and relay blog posts

In short: Engage the community. Be very public about what you are working on and where the roadmap is going. Get management buy-in for your projects to persuade them of the value of opening them to the community (use metrics to demonstrate take-up).

Working on standards

The other thing that has been going on today “behind the scenes” at EclipseCon has been the first meeting of the OASIS MQTT Technical Committee. It is exciting to see that Richard Coppen and Raphael Cohn have been elected as co chairs of the group, with seven sponsoring organisations from across the technology and messaging market and 35 publically-visible members – lots of interest in MQTT!

What a week for MQTT!

Part of my role as WebSphere Messaging Community Lead involves IBM’s MQ Telemetry Transport protocol. I spend a chunk of my time talking about how MQTT relates to building a Smarter Planet, and explaining how it can be used to build some very cool new applications and solutions.

MQTT logoFolks from IBM and Eurotech may have jointly authored MQTT, but it has been published online with terms enabling royalty-free use and implementation of the protocol. The next stage is to put it forward for standardisation. Last Friday, the call for participation in a standards discussion was published on mqtt.org. It’s open to anyone to join, and given the excitement I’ve personally seen in the developer community, I’m hopeful that we’ll see plenty of interest.

Friday saw even more big news, from an entirely unexpected source. As I stood chatting to people arriving at the OggCamp party that evening, my Twitter alerts and email went crazy with MQTT chatter… Facebook announced that their new Facebook Messenger application (a result of their acquisition of the Beluga team earlier in the year) uses MQTT! I’d been aware of different mobile app developers using MQTT for a while now – in fact we recently highlighted what a great match the protocol is for Android applications, on the mqtt.org blog – but had not known about Facebook’s interest or usage. In their post talking about how Facebook Messenger works, they call out the characteristics that make it a strong protocol for a mobile group messaging application – low bandwidth, low overheads, low power cost… all of the things that have made MQTT successful in sensor networks and solutions, make it ideal for these kind of applications as well.

Well… as I said, a big week, with some exciting news. So it seemed only right that I should give a talk about MQTT and all of these latest developments at OggCamp this past weekend – the event which three years ago, resulted in Roger Light creating his mosquitto broker.

You may recognise the slides as a remix of the talk I gave at LinuxConf in January, but I’ve updated them to highlight the OggCamp dimension and to talk about the recent news. There will be more to come during the coming weeks, so join the chat in channel #mqtt on Freenode IRC, and keep an eye on mqtt.org!
