How we will see unregistered users

Hi!

You get this message because you are an admin on a Wikimedia wiki.

When someone edits a Wikimedia wiki without being logged in today, we show their IP address. As you may already know, we will not be able to do this in the future. This is a decision by the Wikimedia Foundation Legal department, because norms and regulations for privacy online have changed.

Instead of the IP we will show a masked identity. You as an admin will still be able to access the IP. There will also be a new user right for those who need to see the full IPs of unregistered users to fight vandalism, harassment and spam without being admins. Patrollers will also see part of the IP even without this user right. We are also working on better tools to help.

If you have not seen it before, you can read more on Meta. If you want to make sure you don’t miss technical changes on the Wikimedia wikis, you can subscribe to the weekly technical newsletter.

We have two suggested ways this identity could work. We would appreciate your feedback on which way you think would work best for you and your wiki, now and in the future. You can let us know on the talk page. You can write in your language. The suggestions were posted in October and we will decide after 17 January.

Thank you. /Johan (WMF)

Query

Hello, David,

I saw you closed Wikipedia:Articles for deletion/Dilar Dirik and I noticed that Draft:Dilar Dirik also exists. The deleted page actually directs the reader to the draft page. Do you think this draft falls within the scope of the AFD? Thanks for considering this query. Liz ^{Read! Talk!} 06:17, 8 January 2022 (UTC)

Unfortunately I think that would be a stretch. The main reason for deletion was speedy G7 and the draft creator, User:Czar, appears unrelated to anyone who edited the article. Maybe Czar would be willing to tag their draft G7 as well, based on the arguments in the AFD? —David Eppstein (talk) 06:24, 8 January 2022 (UTC)

block of 2402:7500:917:30C4:54AA:108F:3ECB:103F

Hi, thanks for blocking the LTA at the above IP. Could you also block the /64 range of that at Special:Contributions/2402:7500:917:30C4:0:0:0:0/64? See WP:/64 - ISPs treat IPv6 /64 ranges like single IPv4 addresses. For example earlier today the LTA was using 2402:7500:917:30C4:F49C:9CA3:EEE6:A404, another IP in the range, so blocking the /64 would be better for preventing block evasion. Thanks, eviolite (talk) 19:28, 14 January 2022 (UTC)

Ok, done. I wasn't aware of WP:/64 before but it makes a clear enough case for how to block IP6's as a general rule. That range turned up another edit to domino tiling which also looks like X. —David Eppstein (talk) 20:07, 14 January 2022 (UTC)

Recent edits in Paulette Libermann

Hi David Eppstein, I believe there have been some misunderstandings regarding my last edits, so I thought it was better to discuss them here. I apologise in advance if I misinterpreted your edit summaries.

Regarding the citations: I was not aware of this difference between citations styles 1 and 2, thanks for letting me know. I have always created them automatically (e.g. using DOI), while, as far as I understood, Citation Style 2 needs a manual input of the various data, so it looks to me a much less convenient method. Is there maybe some argument why citation style 2 should be preferred in general (e.g. it makes easier/better something else I am not seeing)? Anyways, I understand that it was already used before my edits and, according to WP:CITEVAR, it should be kept that way, so I'll try to fix it.

Regarding using Libermann's papers as references about Libermann: in your previous edit you transformed the links to those papers into a separate list of "selected publications". In my last edit I didn't touch those references at all, nor I added new papers, so I don't understand why you claim I kept making the same mistake. Or am I missing something?

Last question: in the previous edit I used Zentralblatt MATH as source (to prove that Libermann had a certain amount of papers), which you dismissed as "search engine results are unacceptable as sources". I thought that zbMATH was a reliable source, since it doesn't simply collect random papers/books but review them as well (unlike for instance Google Scholar, which is indeed much less reliable on this matter). Then would also MathSciNet (which I had not used since it's subscription only, and I thought it would be better to use an open access resource) not be allowed as well?

Thanks! Francesco Cattafi (talk) 22:34, 13 February 2022 (UTC)

The argument is WP:CITEVAR. You should not change citation styles. It is usually a simple matter of using the {{citation}} template instead of the {{cite}} templates. It is easier, because you do not need to choose which of the many {{cite}} templates to use. If your automatic software is incapable of doing that, fix it. As for zbMATH: individual signed reviews on zbMATH are reliable sources for what that paper is about. A search result for all papers by someone is not. Search engine results are always disallowed as links. A carefully curated author profile (like the ones on Google Scholar) can be included in the external links but not as a reference. In general, most of our academic biographies avoid saying "they have published 371 papers". It is not particularly useful information to readers. Why include it? I can't even accurately count my own papers. Instead, a carefully selected small set of the most influential papers and books seems a better choice to me. —David Eppstein (talk) 22:38, 13 February 2022 (UTC)

Unsolved problems and solved problems in mathematics

Hi, @David Eppstein, I would like to ask about the unsolved and solved problems in mathematics. My first question is why the solved problems have been written in unsolved problems of mathematics? Is it better to make a new page about the solved problems in mathematics? Is it better to write about who's solved the problems and what are the solutions (if the idea, that is, to make a new page about solved problems in mathematics, is acceptable)?

Charles G. Häberl

Hi there. Hate to bug you, but could you take a look at this article and give me your opinion? Thanks. Onel5969 ^{TT me} 15:00, 18 February 2022 (UTC)

I'm not much of an expert on religious studies scholars, and tend to stay out of their deletion discussions, because the non-academic side of their notability is somewhat opaque to me. But from the academic side, this one looks ok. Citation counts are low but I think that's to be expected for the field. I would start by looking for published reviews of his books. The Neo-Mandaic Dialect of Khorramshahr has three on JSTOR [1], [2], [3]. I also found one review for The Mandaean book of John [4]. That's enough to make at least a weak case for WP:AUTHOR. President of the International Linguistic Association might also be WP:PROF#C6. So I don't see a lot of reason for questioning this article's legitimacy, and a reasonable likelihood that it would be kept in an AfD. —David Eppstein (talk) 17:41, 18 February 2022 (UTC)

Journal of Schenkerian Studies

Hi. Thanks for all your constructive engagement on the Timothy L. Jackson article. I genuinely appreciate your willingness to have a serious conversation, and I acknowledge that I don't always succeed at being as dispassionate as one would hope.

In that vein... The anonymous IP contributor to that discussion basically bounces back and forth between that page, Philip Ewell's page, and the Journal of Schenkerian Studies page pushing their point of view. (Also the page for Heinrich Schenker himself, but I ain't going NEAR that one.) As I have now reached the point where any more edits on my part on those pages could reasonably be considered edit warring, I was wondering if you'd be willing to have a look at the recent edits to the JSS page in particular? I'm utterly baffled by the distinction being drawn between "biological racism" and "racism," and I don't know how to respond.

Thanks for your time. PianoDan (talk) 03:48, 21 February 2022 (UTC)

It's simple. Biological racism is based on race; cultural racism is based on the differences between cultures. Racism against Blacks in America is biological. Germans' hatred of the French and English after WWI is cultural. Schenker's racism was cultural because he criticized other peoples, especially the French and the English, not other races.

Ewell tried to show that Schenker was a cultural racist by distorting Schenker's quotes. Wiener in the article I added last night to the JSS entry said this. So did Jackson in the Quillette article that PianoDan keeps deleting. Most of the writers in JSS are acknowledging Schenker's cultural racism. Only the Beaudin article is clearly using the term in the biological sense. — Preceding unsigned comment added by 24.184.26.105 (talk) 00:50, 22 February 2022 (UTC)

If you think that race actually exists as a biological rather than social construct, you are mistaken and probably mistaken in a racist way. There is no biological basis to racism. It is all purely cultural. And by trying to distinguish acceptable from unacceptable racism, you are coming across as an apologist for racism and as someone not here to build a neutral encyclopedia. It is all unacceptable. —David Eppstein (talk) 01:42, 22 February 2022 (UTC)

I am not giving my opinion. This is an existing argument. I am only summarizing it.

The point is that Schenker was talking about national peoples--English and French--not Blacks. Wikipedia is not a place to accuse others as racists. — Preceding unsigned comment added by 24.184.26.105 (talk) 03:03, 22 February 2022 (UTC)

If you think that Schenker was not also talking about Black people (and dude, "Blacks" is not the preferred nomenclature) than you have either not been paying attention or are willfully blind. —David Eppstein (talk) 06:47, 22 February 2022 (UTC)

Response to Talk Page Response for Catherine L. Ross

Hi again! So sorry, I'm really new to Wikipedia, so please excuse me if I am fumbling around. I am an intern for a center affiliated with her, I manage a lot of her online websites and it came to the center's attention her Wikipedia had a strange undisclosed paid editing tag. Again, I'm very new to Wikipedia pages and the talk pages I was in prior to this one, told me to come to this page and ask for a review, as I wouldn't be able to review/ edit it myself due to my affiliation, and the Women in Red talk page was super passionate about notable women bios on the website. I looked through her page myself and everything on it seemed accurate, to my knowledge, with sourcing for most of the biography. So I would really appreciate if you could review it or refer me to someone who could review it, and if it still doesn't comply I would be more than willing to ask for sources from around the center if that's what's missing. Thanks again for your response and apologies again for any fumbling! ReginaDevi (talk) 19:48, 23 February 2022 (UTC)

Calculus references

I've been brushing the cobwebs out of the calculus article, since it is highly visible and prone to cruft accumulation. As you might be the project's expert on books about mathematics and its history, I was wondering if you had any suggestions for the references and the (perhaps over-exhaustive) "further reading" section. It would be nice to direct readers to books for which we have articles, where possible. I found a few, e.g., The History of Mathematics: A Very Short Introduction, but it's quite possible that I missed some opportunities.

I don't have the time or the focus to shepherd the article through a formal process like WP:GAN, but I figure improvements here and there will be beneficial anyway. XOR'easter (talk) 08:16, 24 February 2022 (UTC)

I don't have much opinion on this, other than having edited biographical articles on a couple members of the Harvard Calculus Reform Project (Andrew M. Gleason and Deborah Hughes Hallett). I don't actually know much about calculus pedagogy since I'm in a CS department and don't have to deal with it, and I've been tending to avoid routine textbooks in my editing on mathematics book related topics, but maybe what you want here actually is the routine textbooks. I suspect that if it's difficult to find something in those texts, that may be a sign that it's not central enough to be worth mentioning in the article. —David Eppstein (talk) 21:53, 25 February 2022 (UTC)

Derangements

Hi, you reverted my edit of Derangement, commenting “other than using more technical jargon like codomain, how does this differ from the material already in this section?”. It differs in that it's clearer and more concise—at the very least, the hat-check explanation would be simplified if the hat labelled $1$ is relabelled to $i$ after the $1$st person has taken the $i$th hat. lammbda^talk 00:13, 27 February 2022 (UTC)

More concise, in this context, usually means more WP:TECHNICAL. I think this topic should be written in a way that can be understood by people not familiar with jargon like "codomain". —David Eppstein (talk) 00:21, 27 February 2022 (UTC)

In that case, I'll go ahead with the hat relabelling explanation—although I don't necessarily agree that adding an alternative explanation would make the article more difficult to understand, since it's not supplanting the original. lammbda^talk 00:30, 27 February 2022 (UTC)

It makes it more difficult in two ways. (1) People unfamiliar with the terminology will hit a wall of terminology that they don't understand, stop reading, and leave the article thinking that they understood none of it and that Wikipedia is useless for trying to understand mathematics. This happens far too frequently already for Wikipedia articles, because of well-meaning edits like yours. (2) People familiar with the terminology will be confused at why the two new paragraphs look the same as the first two paragraphs of the section, almost as if someone editing the article made a copy-and-paste error, and be distracted from understanding the actual text. —David Eppstein (talk) 00:36, 27 February 2022 (UTC)

Ah, you're right. lammbda^talk 00:38, 27 February 2022 (UTC)

Doubling the cube

My apologies re edits to Doubling the cube. We were stepping over each other's toes. While I was composing my fix, you fixed the article. Seeing that, I backed it up, and my second (last) edit left the article as you had edited it, referring to your fix as the "probably superior" one (as I am not so familiar with the math markup). _signed, Willondon (talk) 16:58, 9 March 2022 (UTC)

Categories

I'm grouping the superclass categories for templates. Please discuss prior to mass reverting. WikiLinuz {talk} 🍁  07:50, 11 March 2022 (UTC)

You are making a royal disaster of our categories. A graph is a mathematical structure; a data structure is a computational structure; graphs should not be categorized as data structures. They are different things. And you are violating our categorization requirements by putting articles in parent categories when they are already in child categories. I suggest YOU stop and mass-revert your own edits before this escalates to the drama-boards. —David Eppstein (talk) 07:52, 11 March 2022 (UTC)

Primary data structures are the ones listed under list of data structures, and I've only added categories to those on the page. Your reverts on the articles listed under the WP:SAL articles don't make sense. WikiLinuz {talk} 🍁  07:55, 11 March 2022 (UTC)

And the categories added to the articles under the list article do not violate any policies. The categories on DS-related articles were incomplete or immature earlier. WikiLinuz {talk} 🍁  07:56, 11 March 2022 (UTC)

A huge fraction of your edits violate WP:CATSPECIFIC. "If a page belongs to a subcategory of C (or a subcategory of a subcategory of C, and so on) then it is not normally placed directly into C." And many others are placing articles into categories for which they are totally inappropriate (mathematical objects like graphs into categories for computer science concepts like data structures). And you are making those edits so quickly that it appears you are using automated tools to do so, making your bad edits more problematic. —David Eppstein (talk) 07:58, 11 March 2022 (UTC)

Template:Data structures should contain Category:Data_structures or the subcategory. But most of the articles do not follow this pattern. And, the category was added to the articles that fall under Template:Data structures but doesn't have any categories. (I'm not objecting to your "graph theory" or "graph structure" related reverts here, to make myself clear.) WikiLinuz {talk} 🍁  08:03, 11 March 2022 (UTC)

Stop making excuses for your miscategorization and start paying attention to WP:CATSPECIFIC. Also, stop using some particular list article that some editor or editors threw together as an excuse for spreading its mistakes across the rest of the encyclopedia. —David Eppstein (talk) 08:05, 11 March 2022 (UTC)

I believe I misunderstood the concept of "subcategories" and "supercategories" in the context of Wikipedia, and how they're inter wired. I will revert myself where an article might belong to a subcategory (categories like a Category:Linked lists, Category:Trees (data structures), Category:Hashing, etc.) and arrange them in accordance with super-categories' page. WikiLinuz {talk} 🍁  08:14, 11 March 2022 (UTC)

So, things that are already in this subcategories shouldn't have Category:Data structures category, right? (since we categorized to the most specific one already). But what about this category like Category:Hashing? Hash tables is best categorized to "data structures" category, but since "hashing" isn't a subcategory within "data structures" (from the link I shared prior), we can categorize them into both of those categories, right? (I believe the "super" and "sub" categories are chosen at the time of the creation of a category?). WikiLinuz {talk} 🍁  08:33, 11 March 2022 (UTC)

Because "hashing" is not (last I looked) a subcategory of data structures, it's not affected by the categorization rules and has to be decided based on the actual content of the articles. But my opinion on the matter is that if it's related to hashing and is a data structure, it belongs in the child category, Category:Hash based data structures‎. So if it was placed in the parent category Category:Hashing, it was probably placed there because it is not a hash based data structure, but is something else related to hashing (like hash functions, which are not data structures). Such an article probably does not belong in the data structures category tree. Categories are for defining characteristics of topics; they are not for listing other topics to which they are vaguely related. —David Eppstein (talk) 08:53, 11 March 2022 (UTC)

I see, that makes sense. Apologies for my misunderstanding of the inter-wiring of categories and subcategories. Thanks. WikiLinuz {talk} 🍁  09:00, 11 March 2022 (UTC)

Self-reverted the categorizations. WikiLinuz {talk} 🍁  09:30, 11 March 2022 (UTC)
