Once upon a time, I was nearly laughed out of the room for suggesting that, someday in the distant future, everyone would have their own computer. Now, of course, you probably have several computers. But you actually have a lot more computers than you think.
Some of your computers are in obvious places, like your laptop or cell phone or game system. But others are invisible to you: In your car. (Your car probably has multiple computers in it already!) In your microwave. In your television.In your refrigerator. In your thermostat. Did you know there is probably a tiny computer inside your microSD card? (It's a modified ARM processor that maps out bad memory location and remaps the file-system so the FLASH memory gets exercised evenly).
Soon, there will be computers inside everything. Imagine your disposable soda cup at the restaurant with a video advertisement playing on the cup! Or food packaging that turns black (or green or yellow) when it's expired. But the next really big step will be that these computers won't just be standalone computers: they'll be networked and able to talk to one another. Welcome to the Internet of Things.
We're offering a class about Maker Technologies and the Internet of Things because, although the future is not quite here yet, you can already start exploring this new world. And begin developing the basic skills that will allow you to start using these technologies immediately.
Some of the skills are basic: Navigating the Linux operating system using the bash shell and a text editor; Applying fundamentals of computer communication and Internet Protocol networking; Programming with Python. Others are more specialized: Collecting and transforming data from sensors using a GPIO; Controlling electronic devices; Building and using client-server applications.
Finally, there's a dark underside to being surrounded by all of these computers: Who really controls them? Are they collecting data about you? Who can see that data? It's imperative to think through the security implications of these systems to prevent intrusions and mitigate their effects when compromised.
The course is being offered by Steven D. Brewer, Director of the Biology Computer Resource Center, and Christine Olson, a doctoral student in the Department of Communication at UMass. They are co-founders of Makers at Amherst Media, a local group focused on building community and making technology accessible to the public.
Former UMass student and entrepreneur Wayne Chang, talking about technology startups recently, identified the Internet of Things as the "next big thing". We agree — and hope you'll join us this summer for Maker Technologies and the Internet of Things July 12 through 25.
