Did you know that any glider-constructible pattern can be made with at most forty-seven initial cells due to the reverse caber-tosser?
Did you know that although there are no known stable 5x pulse dividers, any glider stream with a constant period can be divided by five?
Did you know that the repeat time of a stable glider reflector has been reduced by over two orders of magnitude since the first was created?
Did you know that stable reflectors were known to exist for over two decades before the first was created?
Did you know that despite MWSSes being larger and about four times as rare as LWSSes, it is easier to convert a glider signal into the former than the latter?
Did you know that despite being over nine times as large as a clock, a pulsar is over 150 times as common and requires less gliders?
Did you know that the fishhook is cheaper (in terms of gliders) than nine more common objects?
Did you know that despite sparks always dying by themselves, it is possible to preserve certain sparks forever using only other sparks of the same type?
Did you know that it is possible to construct patterns that temporarily exhibit cubic growth?

One month has passed so a new post for two issues:
LifeWiki:Did_you_know/56&oldid=61721 and LifeWiki:Did_you_know/96&oldid=50601 conflict subtly and may be outdated.
LifeWiki:Did_you_know/154&oldid=103010 is more or less a duplicate of LifeWiki:Did_you_know/100&oldid=62073, and the same topic (stable glider reflector) has LifeWiki:Did_you_know/18&oldid=35847 and LifeWiki:Did_you_know/155&oldid=103011 as well which seems a bit too many.
Also, the DYK column on the wiki main page is significantly longer than other sections - maybe we can display less items, or make it wider?

I don't see a conflict there. The 0E0P was made public on 12 November 2018, enabling an infinite series of (ridiculously huge and un-runnable) strictly volatile oscillators that are powers of its period... whereas the first infinite series of Golly-verifiable strictly volatile oscillators didn't show up until 21 November.GUYTU6J wrote: ↑March 21st, 2022, 12:30 amOne month has passed so a new post for two issues:

For what it's worth, I went through just now and made a minor change to the "wing" DYK item. Something more radical could be done, since "wing" has been used to refer to the lateral edges of a lot of different spaceships, not just Corderships specifically. It's kind of complicated and the full story doesn't boil down to a reasonable-sized DYK. A couple of the other new DYKs might go out of date at some point, but that's not uncommon among DYK's (cf. DYK 88, 89, 90).confocaloid wrote: ↑November 24th, 2023, 3:09 amCould someone other than myself review recent additions to LifeWiki:Did_you_know_archive?
So the new additions seem to be passing my personal DYK criteria for the moment. Not saying that I didn't miss something, though -- other reviews are welcome.

Misleading DYK item:
In this case, I do not see a single simple method to calculate "the number of ticks" that would give 1973 for the first G-to-LWSS posted in Thread for basic questions, and give 73 for the recent G-to-LWSS (G-to-LWSS (2023)).
After said claims about the number of ticks are removed, there's not much left for a DYK item.
Claims about the exact number of ticks to produce the output object from the input object are false precision, when the input and/or the output is a spaceship.

(b) by evolving separately the glider and the stationary device and then combining the results via cellwise "OR" or "XOR",
with identical results.
At T = 79, the output LWSS does indeed appear. However, if you remove the LWSS from that generation, then the temporary beehive does not get restored to the boat. The spark produced by the LWSS at T = 82 is necessary. So maybe it would make sense to say "83 ticks" rather than "79 ticks".
T = 83 is the earliest generation such that for this or any later generation, you can choose either
(a) to evolve the entire pattern for n ticks, or
(b) to evolve separately the output LWSS for n ticks and the rest for n ticks and then combine the results via cellwise "OR" or "XOR",

To define "the number of ticks" for such cases, one would need precise explanations to choose the initial generation and the final generation. I don't think the resulting numbers are going to be particularly intuitive to someone reading a "did you know?" item.
Note also that the documentation of Template:Conduit on LifeWiki directly states that parameters "m" (output orientation), "step", "dx", "dy" should only be specified if neither the input object nor the output object is a spaceship. These values are undefined when a spaceship is consumed and/or produced.

Re: LifeWiki Did-You-Knows
Then both "73 ticks" and "78 ticks" are wrong. There is no LWSS at T = 78 in the above pattern - only a predecessor that lacks the spark. (And later the LWSS interacts again, so it cannot be removed yet.)Haycat2009 wrote: ↑December 18th, 2023, 1:28 amI meant "Starting from the initial catalysis" and "Ending when it first appears"
Why, exactly? Right now it is an unexplained assertion.Haycat2009 wrote: ↑December 18th, 2023, 1:28 amStep for spaceship conduits is actually an important concept, like it or not.
I already explained in my post above, why I consider "the number of ticks from input to output" meaningless when the input object and/or the output object is a spaceship. In these cases, there is no single natural choice for the initial/final generations (especially taking into account actual connections with other conduits in a track).
Template:Conduit says that "step" should not be used when spaceships are involved. In other words there's no concept to begin with (unless you precisely define it for these cases).

Re: LifeWiki Did-You-Knows
Yeah, but it allows for comparison - for example, the first G-LWSS is obviously slower than the smallest G-LWSS, but by your defination, I can swap both and not worry about LWSSes arriving too late, ruining a mechanism. The 1st generation is the first step of the initial catalysis. The last generation is when the spaceship/an equivalent form first appears.confocaloid wrote: ↑December 18th, 2023, 1:40 amWhy, exactly?

That's another story. If you just want to be able to say that one device is much faster than another, then you don't need precise numbers like "1973" or "73" or "27" at all. For example I think LifeWiki:Did you know/176 could be rewritten along the lines ofHaycat2009 wrote: ↑December 18th, 2023, 1:53 amYeah, but it allows for comparison - for example, the first G-LWSS is obviously slower than the smallest G-LWSS, but by your defination, I can swap both and not worry about LWSSes arriving too late, ruining a mechanism.
Note that all the exact numbers are gone (with the exception of the year 2023). Putting those numbers is false precision when there's no single generally understood and accepted way to compute them....that the first stable [[G-to-LWSS]] took almost two thousand ticks to produce the output [[LWSS]] from the input [[glider]], and that has been improved to less than one hundred ticks by [[G-to-LWSS (2023)|a compact converter discovered in 2023]]?
There's still no explanation what counts as "equivalent form", and what counts as "first step of the initial catalysis". And either "78" or "1973" is going to be wrong.Haycat2009 wrote: ↑December 18th, 2023, 1:53 amThe 1st generation is the first step of the initial catalysis. The last generation is when the spaceship/an equivalent form first appears.

EDIT by dvgrn: The DYK with the specific numbers has been completely replaced. Seems like confocaloid's version could still be added as a separate DYK item, if it seems like a good one. I've pretty much stopped trying to think about how to do quality control on the Did-You-Knows, and will instead leave it up to individual objections and suggested improvements like confocaloid's post.

Re: LifeWiki Did-You-Knows
DYK 177 should not exist. This is the LifeWiki, and Dominoplex and B2ein3cijn4cnrwy5cnq6e/S1c2-ai3acny4anqy5c6ek8 are nowhere even close to Life.

Re: LifeWiki Did-You-Knows
My opinion on non-Life content in the Did-You-Knows has always been somewhat similar to this. A big part of keeping things strictly related to B3/S23 was that the alternative seemed to be opening the door to a potential avalanche of notability questions about OCA Did-You-Knows.
I guess I still wouldn't want to see OCA items become the majority of new DYK entries.
On the other hand, if it's just one DYK out of ten or so, that seems like we'll mostly get just a rare occasional OCA tidbit for variety, that ties back to Conway's Life somehow. In this case there's a link to the B3/S23 "Orthogonoid" article. The other two (#146 and #166 are the only other OCA items at the moment, right?) are comparisons with nearby Life-like rules that differ by just one outer-totalistic transition.
We do have the OCA namespace now, and it's starting to get a lot more attention. Maybe we should think about adding a separate OCA Did-You-Know list? Seems to me that idea came up at some point recently, but I'm not finding the reference at the moment.

Re: LifeWiki Did-You-Knows
DYK #179 overlaps with DYK #132 (both are about 12-bit oscillators). I think #179 should be merged into #132.
On the other hand, both Dominoplex and B2ein3cijn4cnrwy5cnq6e/S1c2-ai3acny4anqy5c6ek8 are notable CA rules (OCA Discovery of the Year).
On the other hand, there are sufficiently many notable alien rules to turn the LifeWiki "Did you know?" into a CAWiki "Did you know?" where the majority of items would be on alien rules/patterns.
Currently DYK items mentioning alien rules/objects are #61, #69, #146, #166, #174, #175, #177. Out of these, all but #177 mention Life-like cellular automata (square grid, two cellstates, range-1 Moore neighbourhood, outer-totalistic/neighbour-counting conditions for birth and survival), but not any other rulespaces.

I think at least two out of those cases need some other idea, due to absence of a certain neighbour-counting condition in the rule definition. But it would be better indeed if the errors were understood and corrected by their author.post173619 wrote: ↑December 18th, 2023, 6:10 amEDIT by dvgrn: At least at a first glance, it looks to me like these three proofs are all easy to patch up, basically with the same trick in each case: "Then the dead cell to the left of C will be born in the next generation, via B3 (if the cell 'x' is dead) or B4 (if the cell 'x' is alive)." I've asked Haycat2009 to take responsibility for repairing these incomplete proofs before making any further edits -- and to use edit summaries more consistently instead of just leaving them blank.
