Tactile Marking with Hot Glue

A little dab'll do ya.

If you find yourself forever plugging in a USB cable upside down, holding your Apple TV remote backwards, or otherwise dealing with a device with an ambiguous plug orientation, you can add some tactile feedback by placing a spot of hot glue to indicate the top side. - Gareth's Tips, Tools, and Shop Tales - Issue #74

I'm posting this because whenever we run into a sticky problem, the first words out of Jack's mouth are 'hot glue'. Also, come the revolution, the first ones we're going after are the ones who designed the USB connectors. Gawd I hate those things. I mean why would you design a four dimensional object to use in a three dimensional world? You think they aren't four dimensional? Then why do you have to turn them over three times before they will plug in?
