Re: Golly 3.3 can't find python27.dll

I am using Golly 3.3 to try and run the apgsearch 1.1. I have downloaded python 2.7.16 from the official python website. However, when I try to run a .py file, Golly says "could not load the python library." I am using windows. Why is this? Most likely you either downloaded 32-bit Golly and 64-bit ...

Re: Thread for basic questions

Is it possible to build a "fast HBK" treating the half-bakery reaction as a climber? (probably yes) If so, why hasn't anybody build one yet? (or thought of it yet?) It's definitely been thought of. I remember vaguely working through the implications back when the half-baked knightships were still i...

Re: Synthesis challenges

Re: Langton's Ant unit cells?

But there could be some other issues. How would the grid of unit cells handle multiple active elements (i.e. more than one ant)? And should the cell display the ant's location and orientation that makes visualization more complex with states beyond binary black/white? Yup, just wiring up some kind ...

In my Pi puffer life thread I cannot make the big LifeViewer collections openable. Also,parts of them get removed and (some) a weird line(s) appear(s).

It can also work at any period above 72—although that doesn't look like it will make inserting the spark much easier.

Does anyone know if the dual pi hassler above, at 82 cells, is the smallest known p76?

Re: LifeViewer - Life simulator in HTML5

is the source code available? The short answer is "no". The medium-length answer is that LifeViewer was written as an exercise in learning Javascript, so it would have to be rewritten from the ground up before it would be ready to share. Just the minified-with-Closure-Compiler version of the source...

IMHO most of the agar patterns are easier in the eyes if we showcase them over toruses... Most of the times it's just adding the " :T_width,_height " modifier to the rule.

This (or a variation thereof) might potentially allow a faster-recovery post-elbow-2c/3-to-G... It certainly seems like there are a lot of variants to explore here.
