More Thoughts on Security and the Internet of Things

Attacks that are initially restricted to the realm of esoteric, government-backed spooks become accessible over time to run-of-the-mill cybercriminals.

But the firmware images on many embedded devices are much older than that. The second reason I find it particularly interesting is it targets PHP, a scripting language largely used for web development.

When I was a freshman in college, we had an engineering seminar where the Dean told us that we should expect to re-educate ourselves many times throughout our career. This has certainly been true in my career. In the Web and Mobile development world it seems like if you blink your skills are out of…


Four Approaches to Building Digital Video Processing Systems

Mike Perkins and I wrote an article for Electronic Component News about the various approaches — hardware and software — to building a video encoder or decoder. Raw IC processing power has multiple manifestations including General Purpose CPUs (GP-CPUs), Systems on a Chip (SoCs), custom ASICs and FPGAs. Not surprisingly, all of these approaches can…

The Internet of Things — and How Those Things Phone Home

There’s a lot of buzz about the Internet of Things — a catchphrase designed to encompass a range of embedded devices that connect to cloud servers to act more intelligently than they could on their own.
One problem that comes up is how to design the Thing to connect back to the Cloud Server — how does the Thing phone home? It’s tricky, because, usually, we are trying to balance several factors.
