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.
