Well I tried to search for this but came up empty. Currently solo farming for feathercoin when I see this:
Rejected 000001f9 Diff 8.49M/5432796 BLOCK! GPU 1 pool 0
What does this mean? I solved for higher than the current diff. Did some one else beat me to the punch?
If blocks come in quickly on your altchain, and you were mining solo on your *coind then it doesn't have a way of telling you blocks have changed (like longpoll or stratum), so you risk mining on old blocks and increasing rejects. Lots of ways to improve this, someone else might have time to tell you.
