Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

# Diff the headers and response body of two different urls with curl

COMMAND="diff <(curl -is '$1') <(curl -is '$2')"

if [ $# -ne 2 ]
then
  echo "Usage: $NAME <http://foobar.com> <http://bazqux.com>" 1>&2
  exit 1
