My speeches in no way resemble verbal muck, as you have been pleased to put it in the presence of a lady, but rather a sequence of tightly packed syllogisms, the merit of which would be appreciated by such connoisseurs as Sextus Empiricus, Martianus Capella, and, for all I know, Aristotle himself.'

And so, donna,' Woland addressed Margarita, 'I present to you my retinue. This one who is playing the fool is the cat Behemoth...”

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.
