AKA what i do for a living.
Don't be fooled though -- I actually enjoy doing it: Javascript, ASP (classic and asp.net), HTML, CSS, PHP, a little Ruby. Worked with the Prototype and Scriptaculous JS libraries, Google Maps APIs, and Google Earth KMLs. Work on straight code, and in things like Omniture Publish, Joomla, Convio, Wordpress, Typepad, Blogger, but mostly a nice text editor.
