I found it difficult to sleep last night. The reason is that I attended a symposium yesterday, and was exposed to so many new ideas that I’m having to do quite a bit of processing. Actually, that’s quite exciting. I often enjoy conferences, but rarely come away buzzing from them. Now, I normally wouldn’t write about a conference so soon after attending it, but I wanted to bring a few things to your attention straight away. I’m sure you’ll find them interesting in their own right (at least, I hope you do), and you may wish to discuss them with your students. It’s all part of my quest to show that computing and ICT can be interesting and enjoyable, and not just for geeks.
