I think it was Prominerone. I think he had BFL singles?  I'm sure they're not profitable right now, but they would provide a great learning experience for anyone who wants to know about mining. I hope he is able to dole them out to people would be willing to run them on Uno altruistically.

I keep about 100 ghs on Uno at all times, no matter what. I find about 2 to 4 blocks daily. If I could get some cloudmine hash that I could point at Uno, I would do it that way, but cloudhashing Uno doesn't seem possible at the moment. All the cloudhash I own is at cex.io, but sadly it can only be used in their pools.

I keep a few other low volume sha256 coins moving using usb block erupters, just because I can. The cost in electricity (2w each) is virtually zero, and the computer would be on anyway, so wth. I just do it for fun, and because I like sha coins for their efficiency.  I wanted to know more about 51% attacks so a few months ago I actually did one against one of these coins... rolling it back 5000 blocks to reclaim coins that I had sent to a bad address. It worked (was not a real attack as there had been no transactions in those blocks other than my own muffed up transfer, but the process would have been similar).
