Re: Oscillator Discussion Thread

It's the Python code I posted earlier... ... g.clear(0) g.clear(1) I think you'll find that the only problem here is that you don't call g.new("") anywhere in your script. If you do that, then Golly won't try to record and remember in its Undo buffer every single individual step that your script ta...

Re: Oscillator Discussion Thread

I will not be running the program any more. Whenever I run the program (and don't end it immediately or near-immediately), Golly will not close normally, and when I either start a new file or have to quit, I have to force quit. One time, I decided to keep it going on the same file for as long as po...

{whatever the smallest p76N Herschel loop is}... As of 2012, I think the smallest known true-period p76 gun was this, adapted from a period-doubled version with a smaller bounding box from Jason Summers' guns1j collection: x = 164, y = 64, rule = B3/S23 32bo49bo49bo$30b3o20b2o6b2o17b3o20b2o6b2o17b3...

Re: Oscillator Discussion Thread

Does anyone know if the dual pi hassler above, at 82 cells, is the smallest known p76? (I would imagine it is; what else do we have besides Herschel tracks and glider loops, especially since 76/2=38 and 76/4=19 are unknown periods?) Yup, I just took a quick look at my copies of DRH-oscillators, jsl...

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...

Re: Agar crawlers

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. Some others, like requires far more tweaking. This particular sample is fairly straightforward to stabilize, at least enough to...

Re: Stable signal converters

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. You can get a slightly dirty B-heptomino out at the cost of four gliders, or two gliders plus a Herschel-to-beehive, so it's a 3-signa...

I think that this W->G is new. The glider may look like the default glider output, but it's two lanes off. Sure seems to be new. Might be hard to attach anything to it, though. (?)
