Doesn't work for me:

    $ npm start

    > coder-base@0.0.1 start     /Users/seclorum/hak/coder/coder-base
    > node server.js

    no certificate found. generating self signed cert.
    WARNING: unhandled exception: Error: ENOENT, no such file or directory 'certs/server.key'

EDIT: I figured it out - turns out I had a buggy version of Postgress.app installed on my machine, which had been shipped with a poorly configured openssl binary. Removing this from my PATH, so as to be using the system version of openssl (/usr/bin/openssl) fixed the problem ..
