Today is a national holiday in Switzerland: the Jeûne Fédéral, or national fasting day (here is some related information), although I have to admit I haven't done anything of the sort. In fact I may just have done the complete opposite. Oh well.
I didn't get the chance to put together a technical post for today, but did want to share a book I'm re-reading, 15 years after I first read it, and getting on for 30 years since it was written. This book is an incredible piece of literature, and is certainly the geekiest (in a good way) Pulitzer-winner I've read: Gödel, Escher, Bach: an Eternal Golden Braid by Douglas Hofstadter. I have another couple of Hofstadter's books on my bookshelf and have promised myself I would work my way through them over the coming months. Anyone who has any interest in cognitive science or artificial intelligence (or simply finds fractals cool) will lap this one up, I'm sure.
I won't get into an exhaustive book review - I don't feel qualified to attempt it, in fact I feel incredibly humbled just reading it - but I recommend looking it up on Amazon or Wikipedia, to see what others think about it. I'm a huge fan, that much I can say for certain.
