I worked for a sole proprietorship where every dollar went into or out of the owner's pocket. In winter, the office was so cold that I kept a water bottle that I'd run through the microwave to warm my hands. That was in the days when we still wore ties to work and I kept my jacket on all day, not to be formal but to be less cold.
I think wearing long pants in an office environment is a high risk venture, it results in worse coffee burns :-)
Anyhow I fixed that by getting a spiffy coffee machine that grinds the beans and froths the milk and keeps it at a lower temperture than instant made with hot water from a jug. Because of that I can wear jeans again :-)
I've got to say, I do prefer jeans I can regulate my temperature better and yes barefoot in summer.
Years ago, I kept a kilt in my desk at the office for warm early-spring days before the air conditioning was turned on for the season. When the office got hot, I'd change from pants to the kilt for the rest of the day.
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.
