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
• JavaScript, JQuery, Angular.js, Backbone.js
• Redis, MongoDB, PostgreSQL, MySQL
• GoLang
• CSS/HTML, because you can never master the basics well enough.

The tools I use:

• Git, Unix, Heroku, AWS, Sublime Text 2, RSpec
