One that I especially like is Tech Support Cheat Sheet. Some people do seem to think that just because one has basic problem solving skills and exploits the reversibility of most actions that one is a computer expert.
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.
