You've picked some good ones. I haven't read The End of Eternity for probably 25 years, but it's still fairly fresh in my memory. I'd put that very high on my list of time travel books/movies, if not number one. I think I'll hunt down a copy and read it again.
A Sound of Thunder is very good as well. I just re-read that one a few months ago while revisiting a couple of Bradbury short story collections.
The movie that comes to mind is rather predictable and campy, but I liked it. The Final Countdown. The U.S.S Nimitz gets sucked into a time vortex, arriving off Hawaii on the Eve of the Pearl Harbor attack.
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
