I would have expected to see that come out of Berkeley, not LA! Either way, it really is ridiculous. I realize that people living in other states probably see stuff like this happening in California and laugh at it (rightfully so). They should watch out though, for a trend like this could easily spread like a fungus (and appears to be doing so).
Well you know, personally I can see why people may be somewhat offended by the terms - master/slave. I fully agree though that to officially ban the terms - especially without recommending a good replacement - is over-the-top, futile and downright silly.
What would a good replacement be, anyway ? I cannot come up with one off the top of my head. Master/slave is a good way of explaining in a very concise way what the relationship between a group of parts or machines is, IMO.
