Re: Pattern viewer for forum threads

I'm used to Golly's version of Advance Selection at this point, so I tend to find LifeViewer's floating-selection behavior kind of puzzling -- I don't expect to need an extra [Enter] after advancing. Also, it's sometimes kind of hard to see what the advanced pattern looks like with some themes and s...

Re: Unproven conjectures

Yes, the Eater1 recovers in 3 ticks. But does the last reaction's cell count ? In this case, the RT is 4 ticks. Yup, Scorbie pointed this out several years ago. Probably the intention of the Did-You-Know from which this item was copied was something like " All known glider eaters take at least four...

Re: Stable universal regulator

EDIT: It works! Does it? Better than before, for sure -- but with a p287 test input gun and a p143 drive gun, if you haven't run your pattern and confirmed a p41041 oscillator, you don't actually know if it works or not. Gun periods can be pretty much anything above the repeat time of the circuitry...

Here's the proof of concept for a stable universal regulator using the new L141 conduit: ... A beehive does occur, but it doesn't seem to mess anything up. That's a long way from universal, I'm afraid. You've picked drive gun and test input periods that are both a multiple of 13. If the test glider...

It's probably about time for another NewLifeCA issue or two. I intend to write up an issue on the new c/4 diagonal technology soon (especially given today's new discoveries). Before that, there should be an issue covering the various other Life results... I've done a relatively brief email summary ...

Re: Thread for basic questions

is there anything stopping me from naming the L141 conduit "Lucy"? I can't think of anything offhand. L141 would be the only H-to-H conduit that has gotten a non-systematic name, though. Speaking for myself... I'm probably not going to want to expend much effort trying to remember that L141 = Lucy....

what makes the recently-discovered L141 so interesting? Details can be found here .

Re: Thread for your speculative elementary conduits

L141... Wow! That's a rare one. There are even a couple of completely Spartan versions, in the oldest sense of "Spartan" -- a sidesnagger works, and/or there's no need to weld the eater to the boat, unless additional clearance is needed for the output. And two of them can be chained together: x = 5...

You don't really have to know Python to do that. The script currently has a sample pre-defined character map that looks l...

The word 'transition', as used on these forums, is local forum jargon. It's not a technical term, and doesn't have a single well-defined universal meaning.
