I was hired as a PHP developer, but I'm gradually transitioning them over to Ruby. I still need a manual for both of these languages; PHP for the ludicrous amount of functions (http://www.php.net/manual/en/function.levenshtein.php http://www.php.net/manual/en/function.levenshtein.php anybody?), and Ruby for the frequently confusing code I come across. Ruby is my current hobby language. I also use Javascript for jQuery, and for Node.js in my spare time.
