Improper pseudo-SL separation, it appears.
I'm thinking maybe we shouldn't separate pseudo-SLs with larger than, say, a 10x10 bounding box, because this has happened before as well...

Looks like an improperly separated pseudo-still life; this should be (as best as I can tell) one copy fo xs48_ckjhe0ehjkczcai2s0s2iaczw11x11 and three copies of xs25_g8861v0ccz11dd11. (A fourth one was presumably separated already.)

"Nicknames" are based on apgcodes, so objects with the same code receive the same nickname.

The fact that the same apgcode can in turn encode different objects in different rules is well-known -- see for example xp2_2a54 (the clock), which has several pseudo-variants.

A number of non-totalistic rules containing "v" instead of the correct "n" have been searched, suggesting that someone has been using an older version of my hacked apgsearch. Here's the update to fix: http://conwaylife.com/forums/viewtopic. ... 227#p27227

Use /textcensus/b3s23/C1/sorted to sort by frequency. I made this decision a while ago so as to reduce server-side CPU and memory usage.

Not all that high on the oddness scale, but I'm unable to wrap my head around it: although scorbiclife contributed a haul to B348/S4 way back in February 2015, the pie chart for that rule is, right now, only showing me and C. Wang. What gives?

The root for that haul is missing an "m_" flag that the other hauls have.
This appears to interfere with whatever script generates the pie chart although individual census pages and individual object pages recognize the existence of the haul. The pie chart's percentages would be perfect if the haul from scorbiclife is treated as nonexistent, but for example xp6_7o2zo7g1z1 has two sample soups; one from scorbiclife's haul and one from a different hone.
EDIT: Unrelated, but the odd separation issues people have seen appear to be caused by apgsearch only removing the first extraneous object whenever the pseudo-SL-separation script is called.

I don't think so. The pie chart feature got added in 2015-02-27, over a year before apgmera got released. On the other hand, the haul was submitted on 2015-02-26. I remember that when the pie chart was released, it didn't count already existing hauls.

There are a few other cases of this, where a rule has been barely touched since the beginning of Catagolue. For example, Adam submitted hauls to b36s23/D4_+1 on 2015-02-21, but he is not shown on the pie chart, while the others are.

Ah, apgsearch 1.x hauls have no prefix; that's normal and expected. A prefix ("n_", probably for "new") got added for apgnano, presumably to allow for easy identification of apgnano-generated data in case a bug tainting said data was found. The "m_" ("mera") prefix similarly indicates hauls apgmera-generated data.

That would be the problem then, most likely.

It makes sense when you think about it -- for well-searched rulesyms like B3/S23/C1, it wouldn't be economical to regenerate the pie chart data all the time, not to mention that information on older hauls isn't even necessarily available anymore.

That happens fairly often, it seems -- the number of PATHOLOGICALs in B2e3ai4arw5678/S3-an4ar5i678/C1 has long been one less than the number of sample soups, too. (However, since the number of sample soups now exceeds 500, Catagolue isn't listing them all, so it's not obvious anymore that this is indeed the case.)

8x32 soups should be 8x32 in length, but Catagolue records them as 16x32 (The lower 8 rows are blank)

### Re: Catagolue Oddities

This haul, submitted by muzik, contains several still lifes that are just the soup itself partitioned into objects, dots, and smaller groups of cells. It was committed, making the still life list look massive, when before it was just several 20-cell-and-under still lifes.

I feel like this could shed some light on the error checking that catagolue does, and maybe some extra checks could be done?

Also, to clarify, this rule isn't anything like B/S012345678 where this type of behaviour could be understandable. Plus, the object pages don't work:

EDIT: I'm certain this was a bug in the script and not actual malicious intent, since things like this happen to be pretty common judging by the 44 other replies in this thread.

Well that's perfectly normal behaviour and not concerning at all.

EDIT: oh yay, seems like that was the most recent haul, and nothing has been uploaded since, and it is not certaintly not sticking up to its schedule...

### Re: Catagolue Oddities

Another oddity: Catagolue keeps on getting new non-totalistic rules with "v" neighbor alignment; recent examples include b2cvs and b2c3ae4ai56cs2-kv3-eqv4.

As far as I recall, "v" used to denote the "n" neighborhood; it was briefly used when Catagolue started census'ing non-totalistic rules, used in e.g. b2iv3s123a. But it's long been obsolete, and I'm surprised to see it being used still for new submissions.

In these two cases, yes. I don't have the time right now to check the rest, but here's a list of all rules I know to have been looked at that have a "v":

Code: Select all

b2-a3s2-akv
b2ei3ajkr4-cjrvy5-eiqvy6-ak7-e8s1-c2ak3-acjkr4jrvy5-acjkr6ak7-c
b2ei3ajkr4-cjrvy5-eiqvy6-ak7-es1-c2ak3-acjkr4jrvy5-acjkr6ak7-c
b2i34cik7s23-a4cikv7
b2iv3s123a
b34ajs2-a35v
b35-v6cs2-i34q
b35v7-es23
b35vs23-a
b35ys2-i34qv
b3-e468s2-ck4ekvy6-v
b3s1-e2-cv3
b3s2-i34v

For b2c3ae4ai56cs2-kv3-eqv4 at least, the "regular" version of that rule, using the "n", also exists on Catagolue: b2c3ae4ai56cs2-kn3-enq4.
