Will running a copy of Catagolue locally cost me money? No, it won't. Running Catagolue costs money because it is hosted on Google App Engine. When you run it locally it runs on your own machine and the only cost is the electricity bill. [Edit: ninja'd] I can't find a better place to put this quest...

I can't submit custom inputs using STDIN for some reason; I can use them only as files. Where does the EOF character go? Are you getting stdin by redirecting from a file or by pasting to the console? If the former then the EOL char comes from the file. If the latter then the EOL char can be provide...

Without having looked at the changes you've made to ikpx, I can't say anything with much certainty. But I just want to mention something in case you weren't yet aware. apgoucher has said elsewhere, and possibly here as well, that assumptions about B3/S23 are baked into ikpx in numerous places. You w...

At the OCA thread on adjustable ships, there was a discussion of spaceships with fixed speed and adjustable period. They consist of a spaceship bouncing back and forth between two copies of another spaceship, like this one with a c/2d ship between two c/2o's: #Arie Paap, 22 June 2020 x = 6, y = 17,...

Have all orthogonal speeds 3c/n been proven yet? As mentioned by "2718281828", they're definitely possible, but I don't think anyone has posted a set covering all periods here. I vaguely recall I even had some search results aiming to achieve that result, but I never completed them or posted them h...

Is there a script to convert a non-totalistic hex rule to a MAP rule?

From earlier in this thread: https://conwaylife.com/forums/viewtopic ... 715#p55715

Is this an interesting enough reflection reaction that it would be worthwhile finding p3, p4, p5, and other periodic completions for this reaction? I wouldn't say Definitely No, but it's hard to see where these would be used very often. They'd all be color-changers, and we already have bumpers with...

there is a b-to-r/g that nearly works, but I could not find a way to insert an eater: x = 28, y = 44, rule = LifeHistory 26.C$25.C$25.3C11$7.4B$8.4B$9.4B$10.4B$11.4B3.B$12.4B2.B$13.4B.B7.A$ 14.5B5.3A$13.6B4.A$2.A11.6B.B.2A$.A.A10.D10B$.A.A8.3BD7B$2.A8.4B2D6B$ 11.3B2D6B$12.2BD7B$12.7B.3B$14.5B.B2A$2...

Sadly, for the 9-bit snake, the Mateon1_Glider8_4_5_Test hauls just show random rectangular soups (none of which actually result in the object in question), and the one 5G_stdin haul shows a 0x0 empty RLE. That's because Catagolue itself doesn't support those Test symmetries, so you need to generat...

1. Is it possible to adapt knightt for INT rules? Probably, but given Tim Coe's comments about his own coding style I don't expect it would be straightforward. 2. How to modify dr to support specific INT rules? Also can't help you much with this one, but there is/was a modification for dr to suppor...

Can a gun be made using spaceship converters?

If the converter input is a glider and the output is a different spaceship then a spaceship gun is made by driving the converter with any glider gun having period greater than the repeat time of the converter. Is that what you were asking about?

Is there such a thing called "Whiteship"? There's one :(known a long time ago) x = 49, y = 34, rule = B3678/S34678 11bobobobobobobobobobobo5bo$10bobobobobobobobobobob2o2bo9bo$10b24ob3ob o4b2obo$4b2o4b21o2b2ob3ob2obob3o$2bo2b10ob14o6b2ob2ob2o3b2o$b3obo2b5o 2b16o6b2o$4o2b6obo2bob14obo4b2o$b2obobob4o5...

I think the problem is in test.txt. Possibly it has something to do with how Windows treats newlines differently from Linux. Can you try again using this file? test2.txt Yes, that seems quite likely. The following search pattern causes the same output: 0 0 0 0 0 a b 0 0 c d 0 0 0 0 0 I'm a bit surp...

A c/7o partial that's run into a photon barrel. Via LSSS. <snip supported c/7o> That's very nice. It's not impossible that a p6 gun could be found to support the frontend, but considering that there's no known gun above p4 and that there's only one known p6 oscillator, it seems unlikely. But there ...

double post. please delete.

Bump Probably the first known elementary example from an OT rule; it was found in apgsearch by dmqwerty in May 2020. (The spaceship is 2c/4o, and this oscilllator is p260) x = 10, y = 10, rule = B024/S0123 o$2o$o6$8bo$7b3o! Fascinating OMoS, but are you forgetting the monster which you pointed out ...

It's also possible to extend a partial like this using logic life search, but it would only be feasible to find a completion if it's relatively short. I'd guess that a 10 column extension is doable, perhaps a bit longer if searching for a partial, but currently a new search needs to be run for each ...

Looking through this thread, so much been happening while I've been inactive, but I have been reading during my absence. Thank you everyone for the great work keeping the project going, and special thanks to LaundryPizza03 for keeping an up to date collection and being able to answer questions about...

Can anyone please link to the Russian Herschel Displacement article (I forgot the author)? I think you meant this article about the Pi heptomino by Nicolay Beluchenku: http://beluch.ru/life/crow/crow1.htm Rokicki said he improved a few items in the list, while he also included Iwona in the list. I'...

How do you define 'small'? And as far as I know Iwona is definitely not small. Or are you saying that list is using the measure mentioned below? I was referring solely to the patterns discovered by Rokicki. I agree, Iwona is not contained within a small bounding box, though it's not particularly la...

Are you familiar with WLS 0.71 and Nicolay Beluchenkos WLS version? Nope. I downloaded WLS at the official link and played a bit (but never figured out how to find predecessors etc.) What is Nicolay's modification? Nicolay's modification of WLS is, as the name suggests, a version of WLS (based on v...

2. Much more cryptic is, what kind of restriction did this page use to prevent Trivial Glider+Blinker Collision Pseudo-Methuselah(TM) from getting into the collision? All of the methuselae on that page are contained within small bounding boxes so presumably all the candidate patterns were also cont...

What is sngdetect? From the readme: About sngdetect This program generates patterns that are combinations of common objects, and for each one, it determines what happens when a glider hits it. In particular, it checks whether the original pattern re-appears, possibly translated but at its original ...
