Why is the silverfish so much smaller than the centipede? Long story short, in 2014 chris_c had found a way to support a block-trail-creating "silverfish" front end of a 31c/240 spaceship, using only two streams of upward-traveling spaceships instead of the six in the centipede. The number of upwar...

NewLifeCA #43, 3 December 2023: ever yet more superer diehards, new toggle conduits, engine-collecting, and a new knightship caterpillar Suddenly it has been over three months since the last NewLifeCA bulletin.  It's hard to get caught up properly after such a long hiatus, but I'll give it a try.  ...

I was referring to a loop involving only three-block shifters.

Um. Given that they're shifters and not reflectors, how do you plan to make them into a loop?

Are these puffers [known]? (Moved question to Basic Questions, since these definitely aren't spaceships.) These puffers are probably not in the "knowable" category. Someone may possibly have seen them before, but wouldn't have kept track of them -- there are just too many medium-to-large puffers th...

Is there a three-block shifter loop?

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.

50c/154 helix... 50c/154 is the speed of this H track... Wow, that's ambitious -- Coe ships as part of a helix definitely seem like a first. The Coe ship does seem to do an unusually good job of pushing the burning reaction forward much faster than a glider's normal speed. Has any research been don...

(6,3)c/1024 spaceship: 6,3c1024.mc.gz I feel like this pattern needs a round of applause, or something bigger than "likes" anyway. It's a really impressive construction! The .mc.gz file is 123938x112640, minimum bounding box 123938x112538, population minimum 346912 and maximum 356383 -- smaller tha...

This is not going to be anything checked in Golly, but could be a helpful addition/supplement to everything else that already exists. Hmm. This thread was created with the purpose of collecting terms and definitions specifically to be added to the version of the Life Lexicon that is checked in to G...

Anyone cares to complete... for style points (and repeat time)? How's this for style points? It works at 74/75/78+ ticks due to an internal syringe. The H-to-2G splitter happens to fit exactly with the minimum possible number of Snarks -- no adjustability needed on the north side -- and the trombon...

Probably. It's gotten to be a defined term by this time, but it's not easy to find the definition . The LifeWiki has "spacefiller" and "space nonfiller", but not "space cleaner". I would think the definition would go on the LifeWiki first in this case. It's not a specific small pattern that can get ...

I believe and state it here that your quoted post below is an instance of harassment, directed at me. Sigh... you're quoting my executive decision on this issue. I've re-read it, and it looks to me like a moderator's good-faith effort to improve a difficult situation. I'm pretty happy with the job ...

Why does Catagolue have a hat on the eater 2? https://catagolue.hatsya.com/ Tradition! This has happened in previous years. It's December now -- holiday season. It seems eminently reasonable that something hosted on hatsya.com should add a Santa hat to its icon in December. Switching the eater2 to ...

here to ask for permissions to edit/create pages after procrastinating making an account for like 2 years and lurking on cgolcord (may i have said permissions i want to share my barely successful attempts at rulegolfing) Done! Maybe try posting some of your rulegolfing attempts on the OCA board her...

What is the smallest glider splitter that produces two gliders in the same lane? Assuming you're talking about starting from a glider -- these things are called "G-to-G0" converters. Unfortunately the tandem-glider outputs were too awkward to keep in newer versions of the Elementary Conduits Collec...

I do say that you are intimidating me in various ways. Well, here's the thing. I've got no interest in making you uncomfortable unnecessarily. These discussions are very time-consuming and no fun at all for me either. However, when someone breaks forum rules as often as you've been doing recently, ...

Can eat glider... I experimentally changed the title of this thread to "Patterns involving sparks". If that wasn't the intended meaning, feel free to change it again. Just a note about the glider-eating ability of the dying sparks at the end of the reaction: this is an extremely common feature of c...

What I say is that you (dvgrn) were involved in the dispute on the content of OCA:tlife from the very beginning. You were objecting to my rewording and participating in an edit war with me as a side. You are involved and biased in this disagreement. I'll try a brief response here, but honestly I've...

g-to-ship with dubious usefulness... Apologies for the dubiously useful response, but it's really very strange that those last three catalysts are basically a syringe mounted backwards -- same orientation of everything, just a few cells off the standard position. You're really messing with my brain...

Does this answer your questions? No, it really doesn't. There were two questions in my last post. Both of them allow the possibility of yes-or-no answers. I've asked for yes-or-no answers. You haven't given any yes-or-no answers. So your response doesn't answer those two questions in any way. You a...

You are linking twice to the same post. I believe I already replied to you to the best of my ability. Yes, same post. Not a mistake. Really important questions. Do you understand the LW:DR rules now? When disputes arise in the future, do you intend to carefully follow those rules? If I've missed yo...

I believe I already attempted to reply to your posts, to the best of my ability. Also, multiple people don't use the quote feature on the forums much or at all, without adverse effects on the ability to communicate. There's a difference between replying to posts and answering questions. In my capac...

@confocaloid, could you please try quoting one of my questions, and then answering it? Then repeat the procedure with another one of my questions? That is something that you haven't done yet, during any of our discussions that I can recall. I'm really hoping that it starts happening soon. -- Okay, t...

Transitions are events that can happen, when certain conditions are met. An example of a transition would be "an alive cell survives". An example of a condition would be that an alive cell survives when it has 2 alive neighbours. Question #1: @confocaloid, given our recent discussions, might it not...

what is the difference between "condition" and "transition" when talking about CA rules? Transitions are events that can happen, when certain conditions are met. An example of a transition would be "an alive cell survives". An example of a condition would be that an alive cell survives when it has ...

Old Synthesis for safekeeping... Yikes, that old synth still had one of the "X marks the spot" synthesis steps in it. @Anyone -- what's the best way to locate all the remaining "X marks the spot" stages that are probably still hiding on Catagolue, and replace them with something ... you know ... mo...
