Ouch! Claymore could have just included the copyright notice and there wouldn't have been any problems...
silentarmy's optimization is actually pretty clever, and the original author definitely deserves a credit.
This makes you wonder how much of other people's code Claymore steals without giving credit.
Other of his binaries are "packed" to avoid disassembling. Gee, I wonder what he is hiding.
Well, it's fairly clear that his works are derivatives of other people's works.
Although they are circumstantial, performance indexes of his miners unmistakably point in this direction.
I just thought he was more careful about licensing terms. It would be a real shame if this case is actually true.
