To paraphrase Socrates, the only thing that I know is that I know nothing about programming.
Thus, I'm always re-learning:
- Ruby, Rails, Sinatra
- Redis, MongoDB, PostgreSQL, MySQL
- CSS/HTML, because you can never master the basics well enough.
The tools I use:
- Git, Unix, Heroku, AWS, Sublime Text 2, RSpec
