If you attended my DDD East Anglia talk “A Raspberry Pi2, Azure ML and Project Oxford to unlock that door!” where I integrate a Raspberry Pi running Windows 10 IoT core with the service bus , Project Oxford for face recognition and a Windows Store App to take my picture and hopefully unlock my door. Yes I did bring a door with me. Thanks for attending and for your nice comments.
I have started to put my code up on GitHub. The code for the Raspberry Pi is already there - https://github.com/sdspencer-mvp/RaspberryPi2-UnlockTheDoor. More will appear later as I tidy it up and remove all my config secrets 
I will be repeating this talk at Smart Devs in Hereford on 12 October 2015 and again at DDD North in Sunderland on 24 October 2015.
I’ve just finished presenting my talk on “Successfully Adopting the Cloud: TfGM Case Study”and there were a couple of questions that I said I would clarify.
1. What are the limits for the numbers of subscriptions per service bus topic. the answer is 2000. further details can be found at:http://msdn.microsoft.com/en-us/library/windowsazure/ee732538.aspx
