What do you know today that you didn't know yesterday?

There are two different orientations of right-angle SATA power connectors. I always assumed that they all would be identical, but I went to hook up the DVD drive in the small form factor computer that is my home until the other is fixed, and went to plug things in, only to realize that one of the connectors was bass ackward. Being a Lenovo compact desktop computer, it has a proprietary power supply with two SATA power cables, one oriented one way for the hard disk, and the other the opposite for the DVD drive. That was something of a rude awakening for me, but I was able to make it work with the power splitter that I had on hand.
