Re: Thread for basic questions

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). However,that last likely appeared because I had a Draw brush back then but is pretty weirdly behaving and putting bigger lines. Solution? I went ah...

It can also work at any period above 72—although that doesn't look like it will make inserting the spark much easier. Ah, interesting -- I had missed that detail, that sparking the stable boats works the same way as sparking the pre-boats: x = 40, y = 23, rule = LifeHistory 7.2B25.BABA$6.4B24.B2AB$...

Re: How to OCTA Metapixel

There are also a few pre-built examples of OTCA metapixel patterns in Golly's Patterns/HashLife folder -- the three files that start with the word "metapixel". Turn up the step size in Golly to somewhere between 8^3 and 8^6 before running these. The 'galaxy' pattern is Life in Life, and the others a...

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.

I will not be running the program any more.

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

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...
