I don't have an engineering failure story, but once I sent a multicast to every port of every computer on the college campus of the first batman movie. Our entire switch room lit up like a cristmas tree and the network admin literally screamed.
I was working on a new streaming media server and misunderstood the documentation.
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.
