The thirteenth is actually a lucky number. It represents the number of times the moon cycles through the sky. Just think how much easier it would be to have a calendar of thirteen 28 day months instead of trying to remember which months have thirty-one, thirty, twenty-eight or twenty-nine days.
The fear of 13 is irrational and unsubstantiated.
Just my opinion,
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.
