In a technical dimension I expect to get comfortable with:

• Deep Ruby - Rails/Rack internals, JRuby/Rubinius, EventMachine/RabbitMQ, MongoDB/CouchDB/Redis, Unicorn/Rainbows/Sunshowers, RhoMobile
• JavaScript - Node.js, JQuery, CoffeeScript
• Clojure - LISP on the JVM, looks prety awesome
• Python - rich linux libraries
• Factor - stack-based approach
• Emacs - advanced usage
• Linux tools - bash/zsh, screen, grep/ack
