Have more contributors to open source such as Scala and Spark. I was at a (Apache) Spark conference yesterday and IBM was demoing a Spark interface to iPython 3 notebooks. Something really useful. Microsoft wasn't even exhibiting. Mimic the Unix command line environment of Mac that runs the various untilies (eg, homebrew).
