Two weeks ago, I posted a guest blog from my Colleague Brooks Moses, who was getting ready for a conference, where he was presenting a paper. That event is now done and Brooks is back with his impressions of of NVIDIA’s GPU Technology Conference …
I’m writing this on the evening after the last day of NVIDIA’s GPU Technology Conference, wondering how a single event can be so … Read More
There is still a common misconception that a real time system is simply one that responds quickly to demands. Although a real time system may, indeed, be fast, its key characteristic is predictability. A real time system is deterministic – its response to an event will occur in a timely fashion, neither too quickly nor too slowly.
It is common to use a real time operating system [RTOS - like … Read More
HCC-Embedded (www.hcc-embedded.com) recently released a version of its MISRA-C:2004-compliant TCP/IP stack for Texas Instruments’ Hercules ARM microcontrollers. The stack combines MISRA with HCC’s own coding standard to create a concise C language subset capable of “clear and robust code without ambiguities,” and thus suitable for many safety critical embedded applications, according to the … Read More

This week, I am please to introduce a guest blogger. My colleague Brooks Moses is getting ready for a conference:
Colin has graciously let me use this space to tell you about the things I’m doing to get ready for my presentation at NVIDIA’s GPU Technology Conference on May 15th. So, hello! …
Now, wait a minute, you’re probably wondering; what are we doing talking about GPUs? … Read More
I was having some trouble with my Internet connection recently. I will probably never know exactly what was wrong [as ADSL is, for intents and purposes, magic], but investigating the problem was interesting. I am not a networking specialist, so I would expect that messing with the settings inside a router would be hard, but the manufacturers have made it very simple.
I began to wonder why there are … Read More

As I mentioned in my previous blog, much confusion exists around terminology. I think this is especially true when we speak of recipes and packages in the Yocto context. In the early days of Open Embedded (OE) , on which Yocto is based, there was a very simple relationship between recipes and packages. The relationship is still a close one, but it has become more complicated, as everything does over … Read More
I wrote before about my angle on presentation techniques. As I spend a lot of my time in front of an audience, I have given a lot of thought to how PowerPoint can be used as an effective tool for communication, instead of an instrument of torture.
I would like to share some more of those ideas with you today …
I have 3 tips to pass on in this posting. The first 2 are about starting the presentation … Read More

My recent visit to California, to attend ESC, had many highlights, but a key one was when somebody handed me a book. This was the first time that I had seen a finished copy of Embedded Software: The Works, 2nd Edition. At that point, it had not yet been “officially” published, but the Elsevier/Newnes rushed a modest number of copies for sale at the show and for us to use in prize drawings. … Read More
I am not really sure that I should be promoting this, but here goes …
When I was at ESC the other week, I made the mistake of not hiding or looking frantically busy at some point. The result was that I got interviewed by some guys from ARM about the Stella robot that we were showing and the Nucleus RTOS that powers her. It has now been posted on YouTube.
I do not think that this one is going … Read More
I have historically been somewhat skeptical about open source software [OSS]. I am always wary of anything that is “free” and subscribe to the TANSTAAFL ["there ain't no such thing as a free lunch"] principle. It has taken me quite a few years to understand that open software is not free – it is just a different business model from the usual “we make it, you buy it” approach.
I … Read More
