some things I learned today

learned today:

* installed Go, and thus learned a little about Go package installation
* remembered some things about Python virtualenvs
* it doesn't matter what directory you're in when you run a psql command to, for instance, create a new PostgreSQL user
* when helping a newer team member who seems to be floundering, it really does help with overwhelmption to say "ok, is this a list of all the problems you are facing? ok, let us address them one at a time" and then knock off the easy ones first
* petl is a Python library to make it easier to extract, transform, and load data
