View From The Peak
Welcome to the foremost industry blog covering current issues in Digital Video and Audio, Embedded Devices and Mobile and Set Top Apps. 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.
I’ve got a new blog post up at EE Times, talking about how to architect the network communications protocols for Internet-of-Things devices: Crafting a communications software stack tailored to the needs of your Internet of Things design is crucial — […]
I came across the article “Why the ‘Next Silicon Valley’ is Always Silicon Valley” during my lunchtime reading today and found it really interesting. I would summarize it—obviously not justly!—as follows: Excellence is a snowball rolling down hill. Excellence attracts more […]
The heartbleed bug in OpenSSL has been all over the news. XKCD perhaps had the most succinct explanation. I’d like to take a deeper look at this bug and the process that allowed it to be created. Catastrophic failures are […]
We have recently had several prospective customers approach us who are self-funded startups. Each of these customers was hoping we could help them develop an embedded product to the point where it could be sold on Kickstarter. And each of […]
We’re a little late in posting this, but I wrote a blog entry for EDN last week that discusses how to choose the correct video sampling format. An excerpt: To process signals digitally, they must first be sampled and quantized. […]
In Part One of this blog post I discussed how to state an experiment in the form of probability spaces. Determining the sample space and the event space is necessary to be able to talk intelligently about probability measures, which […]
I recently read this article by John Carbone about using UDP in embedded systems. The advice in the article is accurate, but there are some other issues to consider when designing UDP based protocols in embedded systems that Carbone did […]
One meme that has been making the rounds recently is Joy’s Law, supposedly named after Bill Joy, one of the founders of Sun Microsystems: “No matter who you are, most of the smartest people work for someone else.” It’s a […]
Cardinal Peak’s big data practice is expanding as we continue adding data scientists to our staff. In a recent discussion regarding a data set we’re analyzing, a probability problem conceptually equivalent to the following arose: In a room filled with […]
Hash-based message authentication code, or HMAC, is an important building block for proving that data transmitted between the components of a system has not been tampered with. HMAC is a widely used cryptographic technology. I recently came across its use […]
