DrFPGA: wind river has built an embedded hypervisor(which is a pretty good way to secure applications against malware) , in 10K lines of code. I don't know what micruim has, but lines of code is not a good way to judge it.
@Rick, the growth numbers for Micrium were interesting. Do you know if they are from developers moving up from programming to bare metal or dropping back from more-complex Linux environments? My bet would be on the former.
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.
