Ask HN: Just graduated from a dev bootcamp. What now?

I've just finished twelve weeks at Makers Academy, a twelve-week dev course in London, where I cut my teeth in Ruby, Rails, Sinatra, and a little node.js/Javascript.

What's the next step? I plan on applying for junior dev jobs, naturally. What technologies should I be focusing on to stay sharp and keep learning? If you could go right back to the beginning, what would you do differently?
