I’m helping out with SciFoo for the third year running, which is a blast. Neal Stephenson is back again, which is fun. Anyway, there is always a bit of hurry up and wait at conferences, so I got a chance to finish off this book. Its an ok read, but suffers from the hard-to-believe time travel that The Stainless Steel Rat Saves The World suffered from as well. It was ok though. I’d say 3 out of 5 stars if I had a star rating system.
