Peter Lynds[edit]

Hi -- Thought you might be interested in this: http://en.wikipedia.org/wiki/Talk:Peter_Lynds#NPOV_tag --75.83.65.81 (talk) 00:04, 27 June 2014 (UTC)

Hi David. I see I had the same idea. It would be very helpful if you could take a look at this article and its history. In a nutshell, there is quite a bit of undue content promoting the (unpublished) views in physics of this person. I've attempted several times to redact this content and to add a source (from a peer-reviewed journal article), but the article is being guarded aggressively (a new SPA has already been blocked once for repeated reverts). It has already been at the BLP noticeboard as well (my edits restored by a disinterested editor), but these have been reverted yet again. I think we're at an impasse. Your assessment would be extremely helpful. Agricola44 (talk) 23:07, 5 July 2014 (UTC).

Hi David. Please read my comments on the talk page. I think there are good reasons to hold on to the original, stable version while we talk through the issues. SamW2 (talk) 23:37, 5 July 2014 (UTC)

Hi David. I think your action and comment was really unfair. I'm trying to do this in good faith, and now this. What is crankery about it? What exactly is wrong with the text? Please be specific. SamW2 (talk) 04:54, 6 July 2014 (UTC)

Hi David (again). I remind you of your edit summary. "Revert continued edit warring and POV-pushing by SPA. Despite the edit summary he continues to put back non-notable writings and rewords to make this crankery sound more mainstream. Protection needed?" That followed an edit by myself in which, in good faith, I tried to make you happy by removing some material (crazily, I actually thought it would). That followed an edit by myself in which I tried to merge the conflicting edits of Agricola and myself, to which you said, "Still no. Far too much material of the form "X wrote a paper" which is just not noteworthy." Clearly Agricola has a negative bias towards Lynds work. He wants the page to be negative and also deleted. It's now evident that you hold a similar bias. I've asked what exactly is wrong with including a short mention of Lynd's other work on his BLP page, as it's obviously relevant to it, and have justified doing so on the talk page, though just a quick google search should really be enough. These other papers seem to have received a good amount of attention. Arxiv papers also seem to be fine for BLP pages, as thousands of other BLP pages will show. No one has given me a valid reason why this material shouldn't be included or why it's NPOV. As an admin, you're now threatening to protect a page from editing from me and calling me pov pushing, while Agricola and yourself are clearly pushing a negative POV, and as far as I can tell anyway, I'm the only one who is willing to properly enter into a give and take discussion about it. So, again, what exactly is POV pushing about the text when these papers are clearly relevant to the subject (Peter Lynds) and have received a good amount of attention?

SYSTOR[edit]

Hi David.

Yesterday, I tried to add ACM SYSTOR to the "List of computer science conferences". I see that you removed it.

What do I need to do in order to get it back?

Thank you very much, Doron (cdoron@il.ibm.com) — Preceding unsigned comment added by 195.110.40.7 (talk) 09:29, 7 July 2014 (UTC)

What you need to do is (1) find reliably published sources that are completely independent of SYSTOR that describe it and its impact, and (2) include those sources as references when you add it. —David Eppstein (talk) 15:51, 7 July 2014 (UTC)


All concerns are addressed[edit]

AjoChhand Machine[edit]

All your concerns are addressed, all references are added, please check the publications, those are all highly reputed peer reviewed journal, why do not you see the changes. I am surprised, that you come online and just deleting everything even though your own concerns are respected. I am shocked and surprised.

Sir, I thank you for reverting my recent edit here [1]. Am facing a challenge on the article sir. The article was proposed for deletion by Demiurge1000 (talk · contribs) despite all the good reference from reliable sources I added sir. In my WP:NPOV The article is far better than this [2]. Compare the two article sir. I reali want you to help me on [3] sir. I don't want my selfless effort to be futile sir. Thanks in anticipation sir Wikicology (talk) 19:54, 30 July 2014 (UTC)

That's a WP:OTHERSTUFF argument. You're also WP:CANVASSing. You also haven't yet provided an apology or retraction for this allegation about another editor made without evidence.
As for Sola Olorunfemi, the article relies entirely on primary sources, and associate professors are not normally considered notable. I wonder if being "editor-in-chief of Pakistan Journal of Social Sciences" gets around that problem. If not, that article too may need to go to WP:AFD. I've de-puffed it slightly in the meantime. --Demiurge1000 (talk) 21:42, 30 July 2014 (UTC)

References at abc conjecture[edit]

Dear Prof. Eppstein, I saw all my references were removed by you. I added refinement of abc conjecture and those links were broken now. I'm wondering if you particularly don't like these two sources. The result of Robert and Tenenbaum is on the distribution of square-free kernels(in the language of article, radicals) using the stationary phase methods. With this understanding, Robert, Stewart and Tenenbaum recently made a precise conjecture on this subject. Here is the link to the first paper in mathscinet. [4]

I also added a link to preprint paper. It is not a permenent DOI, but still it is Prof. Tenenbaum's webpage I believe, and is pretty official in my view. [5] — Preceding unsigned comment added by 121.162.206.111 (talk) 09:39, 2 August 2014 (UTC)

There were two issues with your edit which caused me to undo it. First, you added the citations without using them as sources for anything in the article itself, so I didn't think the addition would be particularly helpful for the readers. (I was later pointed to an edit you made before this one where you did use the citations as sources, but I didn't see them at the time because they were not part of the edit where you added the citations themselves.) And second, they are brand-new papers, in one case not even really published yet. Our policy on self-published sources allows for preprints from recognized experts, but as a new primary source it is too new to have accumulated enough citations from other people that would allow us to judge the impact and significance of these works. —David Eppstein (talk) 06:11, 3 August 2014 (UTC)
Well, these authors were recognized experts. For one thing, C.L. Stewart already appeared three times in the reference, and G. Tenenbaum is pretty well known in this field; at least he has 150 papers and 1200 citations only in mathscinet. [6]. But I see the point. I'll come back to this when things are published. Thanks. — Preceding unsigned comment added by 141.223.214.199 (talk) 02:13, 5 August 2014 (UTC)
I do agree with that. Tenenbaum, at least, is notable enough for his own article here, Gérald Tenenbaum, so I think it's clear that he is indeed a recognized expert. It's less that and more the primary nature of the source that I was concerned with. —David Eppstein (talk) 03:07, 5 August 2014 (UTC)

Formal English[edit]

The exclusion of any semantics is an unnecessary constraint for a formal language. Formal languages also include sets of strings of symbols that constrain the strings to strings that also occur in natural languages. Gellish Formal English is an example of such a formal language. Please restore the deleted extensions. — Preceding unsigned comment added by ASHPvanRenssen (talkcontribs) 19:26, 1 August 2014 (UTC)

I think you want formal language to be about a different subject than it actually is about. Maybe you should figure out what that different subject is actually called and put this content there. —David Eppstein (talk) 19:42, 1 August 2014 (UTC)
Looks like you found it? I see you added a hatnote to the formal language article linking to Formal semantics (linguistics), which seems more appropriate. —David Eppstein (talk) 16:59, 4 August 2014 (UTC)

Reviving the WikiProject Computer science[edit]

Hi! I've noticed that the WikiProject Computer science is inactive. I would like to revive it, to improve the coverage of the field. As you know Wikipedia better than I, I would be very grateful if you could give me a hand or some advice. I have summed up my plans on the talk page of the project. Thanks a lot! --Pintoch (talk) 16:31, 3 August 2014 (UTC)

The more-active WikiProject I'm most familiar with is WikiProject Mathematics, but the activity I pay attention to there isn't organized group editing activities — it's more a culture of active discussion on the project talk page and a few bot-maintained maintenance lists (notably Wikipedia:WikiProject Mathematics/Current activity and Wikipedia:Pages needing attention/Mathematics/Lists). —David Eppstein (talk) 19:28, 4 August 2014 (UTC)
These two lists look very useful indeed, I will try to see if I can get something similar for computer science. Thanks! -- Pintoch (talk) 14:02, 5 August 2014 (UTC)

AfD strike-throughs[edit]

Thank you for adding miscellaneous templates to AfD/Vivek Kumar Pandey (2nd nomination). I'd been going to do the same, but sloth prevented me.

However, I wonder about your deletion of:

Keep. As a Cadet and Scientist he is position holder: He visited ICTP, Italy in August, 2004 as visiting scientist to join the course on climate dynamics and he is also position holder in 96 Uttar Pradesh Battalion (UP BN), Jaunpur and thus the Varanasi group of Indian NCC (Army Wing) in 2007.

(plus its markup). I've already twice removed the strike-through (except for the initial "Keep"); I could do it a third time, but this might look like edit warring; plus I can't get so worked up about the matter; plus you're an admin so you should know what you're doing. As an admin myself, I too should know what I'm doing; but sometimes I don't. Indeed, I start to think that here I might actually be wrong -- this has happened on occasion in the past -- and so I pop up on your talk page not to complain but to ask. The reasoning presented for this would-be vote seems IMHO utterly worthless; but (as it's not offensive, libelous, etc), surely this is by the way. While concision is a virtue, somebody who has already "!voted" is able to present additional supporting/opposing arguments later; so all in all what's the inappropriate/objectionable material here other than the dupe opening word "Keep"? -- Hoary (talk) 01:10, 5 August 2014 (UTC)

The reason I did it was that, if I'm not being careful reading an AfD, a struck-through "Keep" with non-struck text looks extremely similar to a normal Keep. The strike-out really isn't very obvious when it's on a short word in a bold font that appears in such a formulaic way in these discussions. By striking the whole comment it makes it much more obvious that there's a repeat, while still making it possible with some effort to read the added text. But if you have some better way of showing the same thing, I won't object to it being changed again. —David Eppstein (talk) 01:13, 5 August 2014 (UTC)
"Keep", perhaps? - Hoary (talk) 09:18, 5 August 2014 (UTC)
Sure, that looks much more distinctive. —David Eppstein (talk) 15:36, 5 August 2014 (UTC)

p = np[edit]

Hi, I was involved in editing p=np, I do not see why you feel a secondary source is necessary there. It's not like anyone will publish that a problem has shown interest outside of the core mathematical community, that's not exactly a journal worthy observation or anything. It is just something obvious from the fact that it is referenced elsewhere, and so those references are the sources. And even if you do think it is just random trivia, the page you cited specifically says that such sections should not be removed, they are better left there than just taken away (see the section about what the guidelines are not intended for). So your removals were unwarranted and I will do whatever wiki says to do next if necessary, so I just ask that you follow the guidelines given and put the section back. It simply detracts from the article to remove the section that shows its reach beyond the core mathematical community. — Preceding unsigned comment added by Kyle1009 (talkcontribs) 04:03, 9 August 2014 (UTC)

See WP:OR, and compare the entry above the deleted ones that does have an appropriate secondary source. Without secondary sources we have no way of assessing the significance of these details to the plot of these works or the significance of these works in the context of the P vs NP problem. It is appropriate to use primary sources (the shows themselves) to source a plot summary in an article about the show, but not here when the very inclusion of the show in the article relies on an interpretation of those plot points as being significant somehow, and WP:OR warns us "Any interpretation of primary source material requires a reliable secondary source for that interpretation." —David Eppstein (talk) 05:02, 9 August 2014 (UTC)

There is no interpretation given, what I said about that is explaining why the material may be of interest. As the section was written, it was a simple list of popular cultural references to the problem, with primary sources (the references themselves). Wikipedia does not support simply removing pop culture references like that, the page you cited shows that it is preferred to be more incorporated, but not removed entirely if not more incorporated. The material is cited and appropriate, it should be put back in.

Not without a secondary source, it shouldn't. —David Eppstein (talk) 22:00, 10 August 2014 (UTC)

Like a hole in the head[edit]

Talk:Lobotomy#Further_discussion BTW, in the link given at the end there, it occurred to me to search for a Traveling Salesman "trope", but all that seems to get us is the farmer's daughter and so on. [7] Perhaps you can think of better search terms. EEng (talk) 18:16, 20 August 2014 (UTC)

TV tropes is one of those sites where you go in with good intentions of just looking for one thing and wake up hours later wondering what happened to the time. But I'm disappointed in the choice of quote the lobotomy link there used — I would have preferred this one: "Friend of mine had one. Designer of the neutron bomb. You ever hear of the neutron bomb? Destroys people - leaves buildings standing. Fits in a suitcase. It's so small, no one knows it's there until - BLAMMO. Eyes melt, skin explodes, everybody dead. So immoral, working on the thing can drive you mad. That's what happened to this friend of mine. So he had a lobotomy. Now he's well again." —David Eppstein (talk) 19:04, 20 August 2014 (UTC)
I always look only just before I absolutely must go urinate, so that my exposure is limited to the EPA-recommended limit of 5 tropes per day. This I've avoided addiction.

Actually, I was hoping you might comment at Talk:Lobotomy since this has been a regular problem there. Not that I'm canvassing or anything. EEng (talk) 21:10, 20 August 2014 (UTC)

Jacob Barnett[edit]

Hi, it's not me that is opposing the use of the Skeptic source for the savant claim. I have no problem with it at all! Viewfinder (talk) 22:49, 10 August 2014 (UTC)

Sorry, I seem to have misremembered. It was Oleryhlolsson that made the edits that I was thinking of. —David Eppstein (talk) 22:51, 10 August 2014 (UTC)

Neil Gaiman and Scientology[edit]

You reversed my inclusion of Neil Gaiman in the category Category:Former Scientologists claiming there is no "textual evidence" he ever was one. Actually there is - first of all the article itself says that as a child he referred to himself as "Jewish and Scientologist" but, moreover, there's this. Downwoody (talk) 04:03, 13 August 2014 (UTC)

The artcle says that his sister referred to herself as Jewish and Scientologist. Not the same. The interview is clearer but I'm not convinced that what he was coached to say at age seven really counts as his (former) religion. —David Eppstein (talk) 04:12, 13 August 2014 (UTC)
It strains credulity to say otherwise. If someone is a practitioner of a religion as a child, as Gaiman clearly was being in a Scientologist family and put forward as a model Scientologist child, and no longer practices by the time they are an adult (or even by late childhood) they are still a former practitioner of that faith. He says he is not a Scientologist, he does not say he has never been one. Downwoody (talk) 11:39, 13 August 2014 (UTC)
If you don't mind, I'm going to copy this discussion onto Gaiman's talk page. Downwoody (talk) 11:51, 13 August 2014 (UTC)

Victoria Kaspi[edit]

As the originator of the aricle on VK you might be interested in commenting on her work (confirmation from Australia) about which I just read (in French) in The Atlantico

Thanks for the link. Alas, my French is not good enough to read it easily in the original — Google translate is still pretty crude even for French to English, but it gets the sense across. —David Eppstein (talk) 06:55, 13 August 2014 (UTC)
Sorry, my fault, I read it wrongly. The confirmation came from the Canadian side. They cite VK's article in the 10th July copy of the Astrophysical Journal LouisBB (talk) 07:36, 13 August 2014 (UTC)

Infinity Cat Recordings[edit]

I was trying to make a Wikipedia page for Infinity Cat Recordings and Wikipedia told me that a previous entry had been made and deleted. I'm not sure what the previous page looked like, but Wikipedia suggested that I contact you about it. Thanks! — Preceding unsigned comment added by Olive875 (talkcontribs) 16:20, 20 August 2014 (UTC)

I can WP:USERFY it for you (i.e. undelete it and move it to your User: area) if you'd like. —David Eppstein (talk) 16:37, 20 August 2014 (UTC)

Yes! That'd be fantastic. Thanks. — Preceding unsigned comment added by Olive875 (talkcontribs) 20:10, 20 August 2014 (UTC)

Yes check.svg Done Ok, it's at User:Olive875/Infinity Cat Recordings. I've enclosed the category and stub tags at the end of the article inside <nowiki>...</nowiki> because user pages aren't supposed to be listed in categories...you should remove that part when you're ready to move the article back into main article space. See also Wikipedia:Articles for deletion/Infinity Cat Recordings for the reasons this article was previously deleted (primarily: lack of independently published reliable sources covering the label in-depth as required by WP:ORG) and therefore what you need to address to make it more likely to survive if someone tries again to get it deleted. —David Eppstein (talk) 20:24, 20 August 2014 (UTC)

Thank you. Except, I'm a bit confused since I am new to using Wikipedia. How can I remove that part? What are the steps I take? Will the article be available to be viewed by the public after I remove that part? — Preceding unsigned comment added by Olive875 (talkcontribs) 20:43, 20 August 2014 (UTC)

You remove that part by deleting the codes of the form "<nowiki>" and "</nowiki>" leaving in place the stuff between them. (This is in the standard editor for Wikipedia; I'm not sure exactly how it looks in the Visual Editor, if you're using that.) But no, that wouldn't cause it to become part of the public part of the encyclopedia; to do that you would need to move the page from your user space to Infinity Cat Recordings (there should be a tab near the top of the page labeled "move", or if you have trouble with that you could ask me to move it for you). I would recommend not performing such a move until you have addressed the concerns from the previous deletion discussion, because if you move it back into the encyclopedia in its current state it is likely to be quickly deleted again. —David Eppstein (talk) 21:05, 20 August 2014 (UTC)
Just want to interject that no one knows for sure how anything looks in Visual Editor. That's part of VE's charm. EEng (talk) 22:01, 20 August 2014 (UTC)

Ok, I deleted the <nowiki> parts. I do need help moving it. I think the page is ready to be moved because we now have articles talking about our label from several very credible sources such as the Huffington Post, The Guardian, and Billboard. — Preceding unsigned comment added by Olive875 (talkcontribs) 21:26, 20 August 2014 (UTC)

Rather than just saying they have press from those sources, could you provide specific references to articles in those sources? Preferably they should also be used to document specific claims within the article. For instance, how do we know that the list of bands given in the article is accurate? Ideally, there should be a source for the whole list or for each entry in the list. See Wikipedia:Citing sources or Help:Introduction to referencing. —David Eppstein (talk) 21:33, 20 August 2014 (UTC)

Alright, I wrote that all of the band names were "retrieved from the Infinity Cat website" and inserted a link which goes to the website that lists the artists. That works, right? They're all listed on there. Do you think that's enough information?

No. You still have a sentence "Infinity Cat artists have enjoyed national press from The New York Times, Rolling Stone, Entertainment Weekly, The New Yorker, NPR and more". The phrasing of that comes across as very promotional and it's also far too vague. What I would like to see is references to specific stories in the NYT etc, with enough detail about the title, date, and author of those stories that other people can tell which stories you're referring to, used to source specific statements in the draft article. —David Eppstein (talk) 22:40, 20 August 2014 (UTC)
Oh, wait. I see I've been looking at the location where I made the copy for you, not at User:Olive875/sandbox where you've been doing the actual editing. Sorry about that. The article is much closer to ready to move back into article space than I thought. Some suggestions for how you could make it better:
  1. Instead of a list of all the artists on the label, it would probably work better to say that some of the artists on the label include ... and then only list the ones that have articles of their own. This is probably the biggest content issue that makes it look unready; the rest are more minor formatting issues.
  2. Where you have just a url as a reference, include the name of the publication (e.g. The Guardian, title of the article, and date of publication as well. See Wikipedia:Bare URLs for why.
  3. What is the difference between an external reference and an external link? Maybe you could have an "Additional reading" section that includes the seven things currently formatted as references at the end of the References section?
David Eppstein (talk) 00:08, 21 August 2014 (UTC)

Thanks for your help. Ok, I deleted the artists on the label who do not have their own Wiki page. As far as your second point, I have put all of the References in the format that Wikipedia wants which is Empty citation (help)  But for some reason the references don’t show up how they’re supposed to. Go to the page and see how at the bottom of the References section, the format for the Guardian is correct now but it links to different things it’s not supposed to. I’m a bit confused about this. Also, I changed it “External References” to “Additional Reading.” Maybe I should just get rid of “Additional Reading” and include those links in the “External Links” section. Thoughts?

Any thoughts? — Preceding unsigned comment added by Olive875 (talkcontribs) 17:20, 27 August 2014 (UTC)

Your DYK re Jim Hart[edit]

I noticed your DYK was on its way out of the current nominations and have reviewed it. My DYK nomination, Template:Did you know nominations/Pierre Thouvenot is also sliding towards oblivion with plenty of commentary but no review yet. I hoped that you might reciprocate but understand if you're too busy. Best regards--Ykraps (talk) 09:39, 22 August 2014 (UTC)

It's pretty typical for reviewers to take a while to get to a nomination; it usually just means a delay. As long as you made the nomination in time it isn't considered expired. But if I find time I'll try to take a look. Thanks for the review! —David Eppstein (talk) 16:03, 22 August 2014 (UTC)
Ah, well that's a relief. I was afraid that once it left the current nominations, it no longer qualified.--Ykraps (talk) 17:30, 22 August 2014 (UTC)

MathSciNet[edit]

David, would you consider listing in MathSciNet enough for a new journal to be considered notable? Thanks. --Randykitty (talk) 13:51, 25 August 2014 (UTC)

Probably not. Their aim is to be comprehensive: every mathematics journal should be listed. But that means that listing carries little information about notability. —David Eppstein (talk) 15:57, 25 August 2014 (UTC)
OK, Thanks, I'll take this to AfD then. --Randykitty (talk) 16:02, 25 August 2014 (UTC)
David, would you mind having a look at that article and the AfD discussion? Based on the above conversation, I took it to AfD, but most people there seem to disagree about MathSciNet. The journal is also included in Zentralblatt MATH. Does that confer notability in your opinion? Thanks. --Randykitty (talk) 17:33, 27 August 2014 (UTC)
Zentralblatt and MathSciNet are very similar to each other. Ok, I'll take a look. —David Eppstein (talk) 17:53, 27 August 2014 (UTC)

Please (1) do not copy text wholesale from AE sites, or copy text without marking it as a quote from the site (2) make sure all information is reliably sourced to publications independent of AE, and (3) do not copy text from those sites either. Otherwise your changes are likely to be reverted again. Also, re your connection to AE: please see WP:COI. As someone closely connected to AE you should probably not be editing the article at all. —David Eppstein (talk) 17:08, 27 August 2014 (UTC)

Dear David Eppstein. Dr Nowak is the manager of the Wroclaw Knowledge Hub of the Academia Europaea (The Academy of Europe)- we have three regional hubs. I (Dr David Coates) am the Executive Secretary of the Academy (of 14 years standing) based at our corporate HQ in London (21 Albermarle Street London W1S 4HS (execsec@acadeuro.org) . We are the Pan European Academy of Sciences Humanities and Letters and are incorporated in UK and also registered as not for profit Charity. We have over 3000 Leading European Academic Scholars as members (including many Nobel prize winners etc). Dr Nowak was asked recently by me to try to update the Wikipedia page which is years out of date and was not even created by permission of the Academia Europaea Board of Trustees in the fist place. It very inaccurate as it stands. (please see our URL www.ae-info.org). I will submit by email one of your permissions statements/authorisations. — Preceding unsigned comment added by 62.49.58.194 (talk) 10:46, 28 August 2014 (UTC)

We do not need your permission to have an article. You do not have any ownership rights of an article here about you. And all articles here MUST be based on reliably published sources, preferably ones beyond the direct control of the subject. If there is inaccurate information about AE floating around, the solution is to get people to publish accurate articles about AE, and then bring those articles to our attention. It is not to try to edit the article yourself using only your direct knowledge of the subject. —David Eppstein (talk) 17:55, 28 August 2014 (UTC)

Decidability of the first-order theory of the real numbers[edit]

Hi. You redirected the article Decidability of the first-order theory of the real numbers to a section in Real closed field. In my opinion, this misses the point: The theory of real-closed fields is just ONE SPECIFIC special case of formalization of the real numbers. There are many more. Especially, people have been studying decidability of real numbers with function symbols such as sine or the exponential functions. This is NOT part of the theory of real-closed fields. Hence I suggest to revert the Decidability of the first-order theory of the real numbers to its original content, maybe adding some of the information from the model theory section in Real closed field. Nahabedere (talk) 08:14, 29 August 2014 (UTC)

Yes, it is one specific instance. It is the specific instance that people call "the first-order theory of the real numbers". So it is the instance that is relevant for this redirect. —David Eppstein (talk) 16:34, 29 August 2014 (UTC)
What do you suggest? What about calling the article "decidability of first-order theories of the real numbers" or something similar? It may be the case that, when saying "the first-order theory of the real numbers" people often really have in mind the first-order theory of real closed fields. But clearly there is more than one first-order theory of the real numbers, and decidability of real closed fields does not cover this.

Nahabedere (talk) 21:03, 29 August 2014 (UTC)

If you have a reliable source that surveys different first order theories relating to the real numbers and their decidability, feel free to use it as the basis for an article. But with the definite article "the" in the title of this one, it seems unambiguously to refer to the theory of real-closed fields. —David Eppstein (talk) 22:15, 29 August 2014 (UTC)
