Only half way through this book but it's one of the best I've read in a very long time. The chapter on Babbage and Lovelace filled me with rapture and awe, and a little bit of jealousy, peeking in on these great discoveries and the heady conversations and frequent advances and discoveries. What must it have been like to work at that level, to discover those things, to be so far ahead of your time? Incredible writing, so well researched, I just love this book... And as a bonus, highly applicable to my day job!
