BokaBB, please don't report your own Sandbox posts just because you're vaguely worried that the moderators will notice Something Bad and suddenly ban you. If you're that worried about a post, just don't post it. Moderators are not going to spend a lot of time patrolling the Sandbox. The Sandbox was ...

wow - no new nominations ? well, here is static conduit glider-to-loafer converter print head technology... Is this second post a pattern nomination, or no? I know the loafer bitmap printer was from 2020, but is this p46/stable cyborg new in 2021? By now, a month or so into the new year, the usual ...

What's the next step now? ... There was some mention of LifeViewer labels. How would those work in Golly? The next step is probably for me to do a trial run of having this script generate readable LifeViewer labels as well as the old-style comments. For variety I'll try doing the ones that only sho...

By the way, is there any python3-compatible version of synthesise-constellation.py that I'm missing?

Yeah, I checked in a Python3 version here a couple of weeks ago, for wildmyron's improved version of the database (duplicates removed, and a subset of 4G collisions added).

... there are actually 3 remaining problems. The first problem is that I need to re-design your frontend (or make a similar frontend that uses the same idea as Upward LWSS + NE-travelling glider = block ) so that NW gliders can travel through the LWSS streams, but I am having trouble with this. The...

Fun fact: The ship that a Herschel creates is from a glider-blinker collision. Suppressing the blinker allows the glider to escape... See HSE19T42 in the Elementary Conduits collection (though it isn't elementary, of course, so it's colored yellow): x = 47, y = 81, rule = LifeHistory D3.D2.3D2.5D3....

Progress I made so far on the above frontend design. It's not much and I'm having trouble figuring out how to complete it. Once the LWSS and XWSS lanes are finished and once the NW glider rakes in the above design is complete (not the blue lone the grey line) I can complete the caterpillar frontend...

Do we have examples of an intermitting glider gun (or intermittent) that can be added to the LifeWiki? (And also, is it related to regulator s?) There's not really any relation to regulators, which take unsynchronized signals and get them synchronized to some particular period. In an IMG, usually e...

The R-pentomino doesn't have to be formed that way. I tend to include the original reaction that I found the reaction in, but should I stop doing that? No need to stop, but maybe make it a little more parenthetical? "(originally found in this reaction at T=227): [ RLE ]". This one had a particular ...

That being said, if you place your blinkers and pre-blocks very carefully, you can get really-long-lived methuselahs with less cells than that. True... except I still would be very careful not to call those "methuselahs", because at this pattern size, there are still probably more of them than ther...

is this considered a methuselah? Not really. There are probably more different Life patterns of that size that last longer than 36,000 ticks, than there are electrons in the observable universe. A methuselah generally starts with a much smaller bounding box and population than that; otherwise you c...

Is that not 15G, instead of 16G? The glider and pattern shown in the middle step is duplicated in the last step, and the initial blinker comes from 2G. Yup, I did the layout wrong -- should have been x = 236, y = 81, rule = B3/S23 214bobo$214b2o$215bo$124b2o78b2o$123bo2bo4bo71bo2bo4bo$123b2obo3bobo...

Observe the interaction in the upper-right starting at generation 227... At T=227 you have an R-pentomino heading leftward, and the fishhook turns it into a century, but the century shows up in the middle of a bunch of already-used territory from T=140 to T=160 or so. Why would a century be useful ...

Is there in CGoL such a thing as "moving" or "flowing" conduits, or signals which act as conduits for other signals ? I am envisioning bi-directional universal construction, with feedback flowing in both directions that modifies the construct... I remember there was a small amount of discussion aft...

Transfer search solved 44, 429 remaining, of which 99 have at least one soup. Thanks for the new list! Here's xs20_8kid2cggzx3543 in 16G, probably improvable with some pain and Seeds-of-Destruction searching, from the last of the five soups : x = 236, y = 81, rule = B3/S23 214bobo$214b2o$215bo$124b...

Has anyone done a systematic investigation of p3 agars? I mean, I don't really know what they're good for, but I wasn't aware they even existed. Gabriel Nivasch did some systematic searches for p3 agars back in 2002: Subject: P3 agar search results I used my toroidal adaptation of Lifesrc to search...

Can there be a LifeWiki page on Hexagonal Life (B2/S34H)? Sure! We didn't create the OCA namespace on the LifeWiki last year so that people would be afraid to use it. A certain amount of notability is still a good idea, but I'd say things can be a little more relaxed in the Wild West OCA universe. ...

Okay, so your source was probably the relevant 2G->P collision: No, I was thinking about this . Aha, yet another category of conduit, where examples have been cropping up for decades, but we don't have a dedicated collection thread. I've been calling them "stop-and-go" or "stop-and-restart" conduit...

I think that I figured out how to get the pi input in a while ago. Okay, so your source was probably the relevant 2G->P collision: x = 104, y = 36, rule = LifeHistory 5.A69.A$4.2BA67.2BA$4.3AB66.3AB$5.4B4.2A5.2B53.4B$6.4B3.A.A2.4B54.4B$ 7.4B3.A8B54.4B13.A$8.4B4.7B55.4B10.3A$9.4B3.6B57.4B8.A$10.4B.6...

are there any known conduits that can edgeshoot a loaf? The best known one is the one in modern highway robber s. This is really a standard H-to-pi followed by a pi-to-loaf: x = 65, y = 43, rule = LifeHistory 62.2A$62.A$60.A.A$59.A.A$55.2A3.A$55.2A2$59.4B$52.2A4.3B$51.B2AB2.4B$ 52.2B2.4B$25.A25.2B2...

What can it connect to?

EDIT: Argh. Why not start conduit searches with actual working input conduits, rather than vague memories or hopes? It's hard to connect up a conduit when one of the stages is a rumor.

Here is a chaos-edgeshooting reaction starting with a Herschel: x = 18, y = 23, rule = LifeHistory 2A$.A$A$2A2$16.2A$16.A$14.A.A$14.2A6$14.2A$14.A.A$16.A$16.2A3$9.3C$10.C$8.3C! I can almost get a Spartan H-to-G out of that with catgl, but not quite (yet): x = 32, y = 36, rule = B3/S23 21b2o$21b2o6$...

My xs20 for today is the lovely xs20_4s39mkiczw121 . Is it known to be easy to spark a mango to kill one of the cells at its pointy ends, as in the sample at right below? I'd like to give the mango another job: x = 59, y = 17, rule = B3/S23 2o4bo43b2o$2o3bobo42b2o3b3o$5bobo47b3o$6bo$51bo$4b2o45b2ob2...

how small can a spaceship predecessor get population-wise? and is it affected by the population of said spaceship? I can't think of a good general answer to this question. It's hugely dependent not only on the population of the spaceship, but also on its structure. For example, predecessors can eas...
