While on the train heading to Paul Graham's Startup School, I brought along quite a bit of reading material. I was hoping to sleep, but I was also hoping to catch up on some reading while I couldn't be distracted with various tasking, email, etc, etc.
For example, the first thing I read was an article on "Software Development Cost Estimating" and I dug into it with interest. I happen to have a very particular way that I do my estimating - which seems to be quite accurate by the way - but I'm always looking out for more and better methods. This wasn't one of them... let me analyze this one step by step.
