@cshore0: I too like "a murmuration of starlings" -- I'd not heard "a blessing of unicorns" before but that is perfect (unless you meet a bunch of the angry and mean kind, in which case you're in trouble [unless you're a virgin, in which case you have other problems]).
I do like a "community of cores" -- and David already mentioned "a wunch of bankers" :-)
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
