I real­ize I’ve turned quiet as far as the blogs are con­cerned. I’ve been work­ing on trans­lat­ing the draft con­tent for the Answer Fac­to­ries book into pub­lished man­u­script. Mark­down is lovely, but talk­ing in detail about the process of soft­ware devel­op­ment still requires an awful lot of cutting-​​and-​​pasting, it turns out….

I recently updated the pub­lished draft; if you’re behind, feel free to go update your copy now. New con­tent includes a descrip­tion of the iPad game Cargo-​​bot, and a detailed test-​​driven re-​​implementation of the game logic in an emu­la­tor we’ll use for GP in forth­com­ing chap­ters. I spent a lot of time on the test-​​driven devel­op­ment, so I’d like some feed­back if you’re willing.
