Coffee in Italy
I enjoy drinking tea and coffee, but I am aware that caffeine is a drug and I am conscious of the implications. Some years ago, I gave up caffeine for a week. It took about two days for the headache to go away. This proved to me that I was physiologically addicted to the stuff [...]

Measuring RTOS performance – a Web seminar
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 [...]

The Italian cuckoo
I have just returned from a short vacation. We have been to Italy. We visited Padua, where my daughter is living for a year, and Bologna, where we have some friends. It was a good trip in lots of ways. A little sunshine was nice. In the UK, we had a scorching March, that made [...]

I am not a networking specialist, so I would expect that messing with the settings inside a router would be hard, but [...]

PowerPoint hints and tips #2
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 [...]

New book
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 [...]

Video
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 [...]

How do you tell the time?
A simple enough question, I would think. Most people would reply with: “I look at my watch.” Or, if they are younger, maybe: “I look at my cell phone.” In any case, there are numerous sources of time all around us. However, there is the question of accuracy. How do you set your watch etc. [...]
