Some groups have 1 engineer working on code. SCM doesn't help too much 1 engineer.
But that said (most groups have multiple people) people who don't use SCM tools are not doing professional work. They can do it this way but they should not be PAID.
Too much 'I don't wanna'...
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.
