Someone (presumably Apple Bottom) found a new (I think) p9 in D8_1: Yup, that's from one of my recent hauls (for the record: "This haul was submitted by Apple Bottom on 2018-09-14 at 00:15:24 UTC"). Also, replying to the older ones--- x = 10, y = 10, rule = B3/S23 3b2o$2bobo$2bo2b2o$2obobobo$bobo2b...

Afraid not --- I'm squarely in the "cargo cult" camp of programming here, so my only idea is this: "Doctor, it hurts when I do this." -- "Don't do that then."

Could you be so kind and stop posting this sort of thing? It's hardly relevant, and not worth notifying every single last subscriber to the thread of.

If you think about this for a few minutes, I think you'll be able to figure out the answer on your own.

I would think that the thrill (both personal and from the community at large) of finding a new spaceship or oscillator would far exceed the thrill of getting a badge indicating the same. I think the question worth asking here is "what are badges supposed to accomplish"? Or, more precisely, "how are...

Looks like the stylesheet didn't load properly. Move along, nothing to see here.

You're probably right. I could've sworn, though... oh well.

Remember that although it was known right from the start that Life was universal (based, indeed, on one of those rather more abstract results previously proven for certain classes of CAs), even the glider wasn't found immediately. Is this true? I thought GoL was only proven universal once some glid...

I think one major factor in the recency of CA research, specifically CGoL, is that, to study the evolution of anything but the most basic patterns, you really need computing power. Before the 1970s, there really wasn't any way to simulate those larger patterns in any feasible time. Mind, CAs were s...

I don't know if this is off-topic, but is there any way we can prove that certain rules are not Turing-complete? B1 rules are trivially not Turing-complete, because every pattern expands at light speed, and so can't do the computation necessary (I believe). Is there some way to prove that any non-e...

I really despise the idea of downloading C++ just so apgsearch can run. C++ is such an unreadable and confusing language that it's really almost impossible to work with. :? You can't really "download C++" as such, but I understand what you mean. I think. That said, even if C++ is unreadable and/or ...

I'm a bit confused by this thread, because the latest version of apgsearch is already compatible with Python 3.x , without needing any further modifications. In fact, calcyman's comments in the link suggest it should be compatible with both 3.x and 2.x. Mind, that refers to the Python parts of apgl...

I installed Golly from the Debian package manager and wanted to tweak my hotkey settings. Since the built in hotkey editor is pretty bad (sorted by keys instead of actions), I can't see a list of all hotkeys there. On Windows, I was just able to find and edit my "GollyPrefs" file, but I can't find ...

...yeah, that defies common sense, not to mention the ample warning given on the wiki.

Slow down cowboy!

EDIT: Calcyman tells me he's fixed this, by increasing the minimum required for that rule.

The object https://catagolue.appspot.com/object/xp4_199aaooaa991/b3s23 displays the correct object and links to soups, but instead of the correct name, it shows "?p4". Perhaps somebody gave this pattern the explicit name "?p4"? Yes, a few objects have names like that: xp3_69ba99b606b99ab96z69d599d6...

For example, :GPSE: and :BLSE: made it in, and they were in the final couple of weeks' changes. Do you see any other "for instance"s, besides the Sir Robin (2,1)c/7 problem? Nope --- that's the only one I spotted (and only because I'd fixed that myself in the source txt). What's the process for bui...

As objects get rarer, why don't we start including discoveries on people's pages for *all* objects, rather than everything but xs<30's? New discoveries are getting rarer, but they're certainly not rare yet. Compare my latest stats update on the wiki; there were (if I didn't miscount now) 223 new ob...

Nice, kudos to everyone involved for your excellent ongoing work!

The latest Lexicon fixes don't seem to have made it into the bundled Lexicon in this release though --- for instance, Sir Robin is still listed as (2,1)c/7 in :spaceship:.

Yes.

Already corrected (but I can't build/push updated lexicons, so it's not showing up anywhere yet).

Noticed this in a quote on the forum - [b]:sparse Life[/b] ... but it is not at all clear that there is any mechanism for these to deal with _the all_ junk produced by switch engines.

Congratulations! I've edited the wiki accordingly, and awaiting Apple Bottom to change the protected number 329 to 59. Oh, oops. The template itself shouldn't be protected -- isn't, in fact -- but I foolishly used it on Template:CurrentNews, which is included on the Main Page, and as a result it en...

I've made some major speed improvements to object detection in apgluxe v4.45-ll1.54 , lessening the effect of 'tail soups'. Can you confirm whether it beats 3.28 on C4_4 now? I just checked, using the same test seed ("MiAmoreCadenza") as before. Here's the soup timing breakdown for 4.45-ll1.54: 0 t...

Because it's highly dependent on the soups themselves, you'll get a more accurate comparison by using the -s option to coerce apgluxe and apgmera to have the same seed and therefore run the same sequence of soups. I'd be interested to see if there are cases in which v3.28 outperforms v4.44 on the s...
