I finished off William Barton's
Radio Silence. It was an enjoyable read, and one of the better "Gray Goo" stories I've read. Though the ultimate solution puzzled me, and left me wondering why it wasn't implemented way before. I may need to go back and reread the last few pages.
I'm going to start working my way through Jeremy Silman's
How to Reassess your Chess 4th Edition. It's a huge chess workbook, and I expect it to take up most of my free time over the next few weeks. I only wish it was available as an ebook. I'm tempted to order
Lessons with a Grandmaster instead, since it is available as an ebook, and the sample was very good.
