Interesting licence terms on WordWeb - you can only use the free version permanently if you make a return flight at most once a year, otherwise it's only free for 30days. Not very enforceable, I'd say, but an interesting way of discouraging excessive emissions (or at least making money out of it...).
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.
