  • Video about a C++ “flaw”
    My latest video blog is now available. This time I am looking at an interesting aspect of C++, where there seems to be a small design flaw. You can see the video here or here: Future video blogs will continue to look at topics of interest to embedded software developers. Suggestions for topics are always […]

  • How I do cooking
    If I start listing my interests, away from embedded software, there are a fair number. I have often written about photography, but others include reading/writing and food and drink. I have written posts in my “6 of The Best” series covering drinks, food and cheese specifically. There has never been a list of my favourite […]

  • ESE Kongress
    This week I am on my travels again. I am attending Embedded Software Engineering Kongress in Sindelfingen, near Stuttgart, Germany. I have attended and presented at this conference quite a few times before and was pleased to be invited back again. On this occasion my talk is How to Measure RTOS Performance. If you are […]

  • Photos that are not pictures
    As I have written about before, when I am not thinking about embedded systems, one of my main interests is photography. I have been taking pictures all my life, but, in recent years, I have started to think more about what I photograph and why I do it. I regard this as evidence of an […]

  • RTOS event groups
    This is the latest in my occasional series of posts about RTOS features and I want to talk about event groups – also called event flags. This is a feature available in many RTOS products, including, of course, our own Nucleus RTOS. Although my comments are inspired by the Nucleus implementation, they are very similar […]

  • A reward for donating blood
    This is a subject that I return to from time to time, as it is a matter about which I have strong feelings. Hence, I offer no apology if I am repeating myself. My simple message is that most healthy adults are able to give blood, with absolutely no ill effects to themselves. If you […]

  • Video about RTOS semaphores
    My latest video blog is now available. This time I am looking at semaphores with a real time operating system. You can see the video here or here: Future video blogs will continue to look at topics of interest to embedded software developers. Suggestions for topics are always welcome via comment, email or social networking.

  • More on what3words
    A few weeks ago, I wrote about a technology that was exciting me: what3words. Since then, I have been giving this matter a lot of thought. As I have gone about my usual business – traveling for work, leisure activities, photography-related engagements – I have constantly stumbled across situations where what3words could have made my […]

  • It is just not fair!
    I have long been of the opinion that anyone with the last name Adams is a genius. It started with the late [great] Douglas Adams, but, nowadays, I am likely to be talking about Scott Adams [author of Dilbert cartoons]. He seems to have a constant stream of interesting ideas. Some are rather off the […]
