Re: Unfinished Herschel Climber (28,3)

just to mention the HBK reaction... Isn't that an "uncontrollable glider". Not that I can see! In the various HBKs, here's what makes the perpendicular output gliders completely controllable: x = 103, y = 29, rule = B3/S23 100bobo$32bobo65b2o$32b2o67bo$33bo9$89b2o$21b2o56bo8bo2bo$11bo8bo2bo54b o9bo...

Re: Unfinished Herschel Climber (28,3)

ideally, the debris could be converted to one or more spare gliders, so we could build another caterpillar based on it. If some or all of the objects in the debris can be used as one-time turners or splitters, it may be possible. There is a long boat in the debris, which may be useful. Um. It's cer...

Re: Spaceship Discussion Thread

After building my newest sawtooth, I realized that its ignition mechanism could also be used for a spaceship. This makes my recent high period diagonal c/4 spaceships obsolete. Here is the new design which allows for a much lower period... I really like the fuse design with the glider stream burnin...

No, it still doesn't explain what the . in ./zfind is A period in that context just means "look in the current directory". Two periods would mean "look in the next directory above the current directory". (Unfortunately, three periods do not mean "look in the next directory above that"... that would...

Perhaps more controversially, should O(sqrt(log(t))) be moved to make use of the √ character?

in terms of hive five oscillators, it might be a better idea to collide gliders... 63 is quite close to 61, the repeat time of the speed tunnel, which is kinda sorta as low as you can go with an engineered X-to-V-spark converter where a single signal gets split and synchronized to make a V.

Re: Defining volatility for spaceships

In my opinion, only strict volatility is defined for spaceships - technically, the volatility of all spaceships is 1 or it would be a puffer/wickstretcher. Not sure what you mean by "technically". Wouldn't the volatility of, let's say, a very long pufferfish spaceship technically be lower than the ...

Just a question: If the Mikipedia pages are just irrelevant, can you just move them to a new wiki for this?
Anyone is certainly completely welcome to do this. It just won't be a new wiki on the server that hosts the LifeWiki, with a "conwaylife.com" URL.

Yes, there are the adjustable oscillators from way back, and then this modern construction by David Bell seems like it must count as a loop. The link is right there in the three-block shifter article.
