Upgrading to Vista

I just upgraded to Windows Vista – the Home Premium version. I haven’t had enough time to develop a fair view of the new OS, but I’ll be writing a comprehensive account of my thoughts on Vista sometime soon. My early impressions are that, first, the interface is quite nice and a definite improvement, and, […]

What are your chances of dying?

As an avid mountaineer and extreme sportist, I often face barrages of criticism from people questioning my common sense. I routinely have to defend myself against people questioning my desire to live. “It’s so dangerous!” they say, “aren’t you scared of ending up like Mallory?”.

More on Moore’s Law

Most people will have heard of Moore’s Law, that the number of transistors in microprocessors doubles every two years. For example, in 1970, Intel’s original microprocessor, the 4004, had a few thousand transistors. Today, state of the art processors have on the order of half a billion transistors. While these statistics are certainly very interesting, […]
