Also, when did the old HP Semi group (aka Avago) become a Singapore company?

Does that mean for tax (or tax evasion)reason, it is registered in Singapore, but for business reason, it still likes to claim itself a US company?
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.
