Re: PotY 2020 Nomination Thread
Another issue is that, as far as I can tell, there's no set end date for voting. Unlike with nominations, I believe there should be a specific date and time when voting should end. The voting period needs to be long enough that infrequent visitors have a chance to vote. Back to my earlier point: alt...

Re: Spaceship Discussion Thread
How did you find that? I found the small 2c/6 tagalong back in 2010 . However, I did not have a way to support multiple copies at the time. Then in 2016 I found this p6 ship which would have solved the problem, except the leading p3 part was too wide. Even using 117P9H3V0 didn't work: x = 33, y = 9...

Re: qfind - a spaceship search program
It would depend on your compiler. I suggest searching the web for how to use OpenMP with your compiler. If you figure it out, it could be helpful to other users if you post your solution here.LaundryPizza03 wrote: ↑February 2nd, 2021, 4:54 pmHow do I determine the equivalent of -fopenmp on my system?
