      # fixtures transaction; from the model's standpoint, the completed
      # transaction is the real deal. Send commit callbacks to models.

      # If the transaction block raises a Rollback, we need to know, so we don't

Here's the idea,

You work in tech. You're in the NYC area.
You care about "people" issues. You think the hardest problem in computing is "people".
You are interested in how we work. How to structure work. How to work together.
How to help your colleagues succeed. 

And...

There's so much to learn:

a = { foo: 'foo', bar: 'bar' }
b = { foo: 'fooo' }

# Reconcile duplicate keys
a.merge(b) {|k, old_v, new_v| [old_v, new_v].min}
# => { foo: 'foo', bar: 'bar' }

# Ever wanted Hash#map to return a hash? This is a workaround
a.merge(a) {|k, v| v.upcase}
# => { foo: "FOO", bar: "BAR" }
