@antedeluvian: I seem to remeber someone making the apt suggestion of a shiver of sharks. In my case would work for snakes as well.
A "shiver of sharks" is an "official" one -- they don't use that for snakes although I agree it would be apt (as would a "scream of spiders"). You can have a "knot of snakes" and a "rhumba of rattlesnakes".
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
