@astrid AAAA is also a battery! Very uncommon but you can still get some if you know where to look for em! 9V batteries sometimes have six cells slightly smaller than AAAA inside of them, too.

@anthropy I remember poking my paw at Dreamweaver once and hating the experience so much (as well as the garbage code it spat out) that for the entire rest of the class I hand-coded 100% of the html, css, and javascript myself, and I got way better results than the entire rest of the class.
