View From The Peak
Welcome to the foremost industry blog covering current issues in Embedded Devices, Mobile & Web Clients and Digital Video. You'll also find specific information on a wide range of other issues including hardware and software/firmware design; and video, mobile application and signal processing technologies. We cover a wide range of industries including security, cable/satellite, enterprise video, oil and gas, law enforcement, smartphone, defense and communications, among others.
Attacks that are initially restricted to the realm of esoteric, government-backed spooks become accessible over time to run-of-the-mill cybercriminals. Take, for example, the Linux.Darlloz worm, which attacks embedded devices and is interesting for a couple of reasons. First, it propagates by exploiting a vulnerability that was patched in May 2012. 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 […]
I’ve got a new blog post up today at EE Times, discussing how to secure devices on the Internet of Things: It used to be academically interesting, perhaps, that an attacker could compromise an unconnected home thermostat. Today, it’s another […]
We recently needed a simple C++ class for linear phase FIR filtering, and I figured it might be useful to others, as well. You can download it here. Here’s how to use this class: Specify the desired filter type (low-pass, […]
Originally this was going to be a blog post ranting about remote controls for home entertainment systems. For the most part, they have way too many buttons! I don’t think I have a particularly high-end setup at home—but I still […]
One of my partners pointed this Slate article out to me about healthcare.gov. It is clear at this point that there have been a ton of embarrassing problems with the rollout of this site. I don’t want to get into […]
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), […]
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.

Regression testing is a simple (and wonderful) idea. The idea is that once you have working software, you should easily be able to ensure it keeps working after further changes are made. This is achieved by constructing a set of tests along with their known-correct outputs, and then re-running these tests after any modifications to ensure the known-correct outputs are still obtained.
