Congratulations, Dave, and Andy. Nice to see someone make a courageous move and have it pay off.

If you haven’t read these books yet (and you’re a software developer), you really should do yourself a favor and make the time. Don’t let "Starter" in the title fool you. Sure, the books are about fundamental and could be used as a "starter kit" (as the name suggests). But, greatness is (almost always) built on strong fundamentals, and you’re never too good to need more practice.
