Re: Thread for basic questions

OK, another question Independent of whether we have a constructor at both ends or not, has anyone built a Gemini-like spaceship that uses streams of LWSSs instead of gliders to store the instructions? This would be less compact overall, but it would minimize one of the dimensions. It seems straight...

Re: Like button in forum request

I also think that the sprites for the like button should be switched, where it would be hollow by default and filled in when you like a post. This would give liked posts a higher contrast with the rest of the page, and stand out relative to other posts. If this is something we can pick I'd make it ...

Re: Logic Life Search

Is there a way to constrain the population of each generation, rather than just the first one? Yes. In the develop branch you do -p followed by the population constraint, followed by a list of generations to sum over. So for example -p =40 7 means generation 7 must have a generation of 40. -p <100 ...

Re: Golly speeding up

I also set QuickLife to step size 2. I don't think there's anything magical about 10. If anything I seem to remember that QuickLife works in 2s, so that areas of ash containing still lifes and blinkers become unchanging. That might just be lifelib though.

Re: Golly speeding up

I'd advise changing the step size in File > Preferences > Control > Set default base step to "2" for HashLife, instead of "8" -- that gives much better control over simulation speed, at the cost of having to hit + or - a few more times, on occasion. Does anyone actually like 8? We could just make 2...

Re: Thread for your script-related questions

I don't think that's likely to work, because oscar.py/oscar.lua relies on the idea of keeping track of a list of just the lowest hash values in a range of tested generations. For a period-P pattern I don't see how you can be sure that you're going to find the matching hash value until you've tested...

I think I did calculate it last year but didn't post it. Of course the threads are still there, so you can calculate it if you want. It'll just take a bit of boring data entry.

I believe B14/S0124V is a valid rule for the above pattern? Not quite. It contains black dots with red surrounds in the top right and bottom left, so it wouldn't be stable under B14/S0124V but would under B01/S0124V.
