For a long time I have not found more interesting book in the field of software, because of new developments and trends you will be better informed by journals.
The past 15 years, I am programming for working days in Python and really bad the source of our team certainly is not.
Through the book me some opportunities for improvement were aware that ever firmly integrated into everyday life.
So there was not only in the "yes, you should even if time is ...." (so that in finally everything remains the same). No, it can be seen clear improvements in our team.
The book was also well received by colleagues.
So: The book is really recommended for those who for some time more so programmed only in passing.
