Very small Turing machines
I am pretty busy with work now, so one of the things I had planned to do – write a simple Turing Machine in Groovy – will have to wait. In the meantime here are some very small Turing machines to wonder over. Related articles A turing machine in 133 bytes of javascript (swizec.com) Is […]

Stirling’s approximation
Trying to find a way to calculate the factorials of large (very large) numbers, so as to at least work through my example for Uranium 235 that I considered when working out, for my own benefit, how the binomial distribution worked. Got this via Twitter: https://twitter.com/#!/Our_Frank/status/141032793961529344 In fact, wikipedia states the approximation in a slightly […]

The binomial distribution, part 2
(Part 1 is here – these notes are to assist me, rather than contain any real news!) So, if the probability that an event will happen to a single entity in a unit of time is and the probability it will not happen is , what is the probability that a large number of events, […]

The tyranny of the arts graduates continues
I imagine in Michael Gove‘s world, this has been a good week. The UK’s secretary of state for education has been in the news a lot this week, and that seems to be the key metric for him – after all his qualifications for the job essentially seem to be that he was once a […]

An example of the poor editing in O’Reilly’s “Programming Android”
OK, I don’t really want to sound like I am bashing this book – Programming Android: Java Programming for the New Generation of Mobile Devices – because, by its very nature, writing a technical book must be highly demanding in terms of accuracy and I see no signs of any mistakes – just what I […]

Making sense of Android’s complex development process
Back in about 1997 I bought a book about this new programming environment – it seemed something bigger than a language but smaller than an operating system – called Java. Back then the idea seemed great – write once, run anywhere – but there was a lot of scepticism and, of course, Microsoft tried to […]
