+
+This is a detailed account of the work done to build Colossus at Bletchley Park during WWII.
+There is a lot of information that I haven't read elsewhere, including a lot of detail about the individual Fish links and variants of ciphers used by the Germans.
+
+A lot of the details are reserved for the appendix, so you can follow the narrative without getting too bogged down.
+(I've read so many accounts of wheel breaking, wheel setting, and so on, I did skip those passages in this book.)
+
+I took lots of notes and learnt quite a few things, and something I was struck by is the number of parallels to modern software development.
+Although the output looks very different, many of the design principles look very familiar.
+
+I'd recommend this for anybody interested in the history of Bletchley Park.
