== Mathbot and disambiguation pages ==
 
Hi, I've noticed that Mathbot adds pages to the "List of mathematics articles ..." articles based on transclusion of the {{tl|mathdab}} template. Problem is, that leads to these articles having links to disambiguation pages. For instance, [[List of mathematics articles (S)]] links to no less than 41 disambig pages, as you can see [http://toolserver.org/~jason/disambigs_in_an_article.php?title=List_of_mathematics_articles_(S) here]. This is a problem for the [[WP:DPL]] project; not only does it give us false positives for which articles need fixing, but eventually we want to use a bot to tag articles with excessive number of dablinks (the {{tl|dablinks}} template that was on the article a few days ago); this would lead to a once-a-day edit war as one bot adds the tag and the other removes it.
 
Since all of these dablinks are intentional, there's an easy solution: [[WP:INTDABLINK]]. It's a convention we use to identify dablinks that don't need "fixing", and our Toolserver scripts are instructed to ignore links with the INTDABLINK format.
 
For instance, say you have a link to '''<nowiki>[[Secant]]</nowiki>'''. To mark it as intentional, pipe it through the (disambiguation) redirect: '''<nowiki>[[Secant (disambiguation)|Secant]]</nowiki>'''.
 
The logic is, if you're linking directly to a (disambiguation) page, it must be intentional. (For instance, the {{tl|otheruses}} template.) So we tell our reports - the same ones that will eventually be used by the bot - to ignore links like this. This works even when you link to a redirect with (disambiguation) in its title.
 
Do you think you could modify your bot to use this syntax when you get articles that transclude the {{tl|mathdab}} template? Thanks, --[[User:JaGa|<b><span style="color:#990000;">Ja</span><span style="color:#000099;">Ga</span></b>]][[User_talk:JaGa|<span style="color:#000000; font-size:small;"><sup>talk</sup></span>]] 03:33, 14 January 2011 (UTC)
 
:I don't think that would work. I routinely use this page to do joins in the toolserver database: the canonical way to get a list of all mathematics pages is to make a list of pages linked directly from one of the subpages of [[list of mathematics articles]]. If we changed so that it doesn't link to the dab pages, then those dab pages won't show up in our lists based on pagelinks.
 
:I appreciate the maintenance script problem, but it would probably be simpler to just tell the tool that lists pages with too many dablinks to skip the lists of mathematics articles, since we know they will have lots of dablinks. &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 03:14, 15 January 2011 (UTC)
::It would still link to the dab page; [[Secant (disambiguation)]] redirects to the dab page. --[[User:JaGa|<b><span style="color:#990000;">Ja</span><span style="color:#000099;">Ga</span></b>]][[User_talk:JaGa|<span style="color:#000000; font-size:small;"><sup>talk</sup></span>]] 03:27, 15 January 2011 (UTC)
:::So... any decisions made about this? --[[User:JaGa|<b><span style="color:#990000;">Ja</span><span style="color:#000099;">Ga</span></b>]][[User_talk:JaGa|<span style="color:#000000; font-size:small;"><sup>talk</sup></span>]] 04:59, 5 February 2011 (UTC)
::::It won't work to link to a redirect instead of linking to the page itself, because that will not put the correct entry into the pagelinks table in the mediawiki database. The actual target of the link matters here, not just the eventual destination you would get to by clicking on the link. The best solution is to have the maintenance script skip any page whose title starts with "List of mathematics articles". These pages are intended to link to dab pages if the dab pages are in the scope of the math project. &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 14:37, 5 February 2011 (UTC)
:::::I'm not going to hard-code article titles into the scripts, for obvious maintenance reasons. I've got a Toolserver account myself. Could you let me know more about what you're doing? I could probably write a solution for you. BTW, why are you answering instead of Oleg? --[[User:JaGa|<b><span style="color:#990000;">Ja</span><span style="color:#000099;">Ga</span></b>]][[User_talk:JaGa|<span style="color:#000000; font-size:small;"><sup>talk</sup></span>]] 17:37, 5 February 2011 (UTC)
::::::I help maintain the bot that updates the list of math articles. It runs from the 'wpmath' multi-mainatainter project on toolserver. Oleg is not as active anymore, although it's usually possible to get him by email. So it's faster for me to respond.
 
::::::The bot goes through a list of mathematics categories and makes a list of all articles in those categories. The list is useful for people who want to browse through math articles, and also useful for maintenance.
 
::::::In its maintenance capacity, I use queries something like this, which makes a list of all math articles that have prod tags on them:
 
<syntaxhighlight lang="sql">select art.page_title
from page as art
join categorylinks on art.page_id = cl_from
join pagelinks on pl_title = art.page_title and art.page_namespace = 0
and pl_namespace = 0
join page as src on src.page_id = pl_from
where src.page_namespace = 0
and src.page_title regexp '^List_of_mathematics_articles'
and cl_to = 'All_articles_proposed_for_deletion'
order by art.page_len asc;
</syntaxhighlight>
 
:::::::If the list of math articles linked to a redirect instead of linking directly to the article, this query would fail to find those articles, because the necessary entries in the pagelinks table for the third join wouldn't be there.
 
:::::::I use similar queries for many other things, for example to make a list of all non-free images on math articles. The key point is that if you join the pagelinks table against all the subpages of [[List of mathematics articles]], you get a complete list of mathematics articles that can itself be joined with other tables in the database.
 
:::::::This is an example of a time when it is perfectly correct to link to the dab pages, because we want the links to the dab pages to be in the pagelinks table.
 
:::::::I don't see it as worth a significant amount of effort to completely redesign our system simply to avoid linking to dab pages. It's trivial to just skip the lists of math articles in a dab-fixing tool. Or not; if someone changes them accidentally, the math bot will fix it the next time it runs, no real harm done. &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 12:56, 6 February 2011 (UTC)
{{od}}(Sorry for the long absence.) I started looking at the data today, and noticed there are already many redirects on these pages. For instance, [[List of mathematics articles (M)]] has 39 redirects that I can see (for instance, [[Mann's theorem]] and [[Metra Potential Method]]). I'm still going to take a stab at the query, I just wanted to let you know it would be an improvement beyond its usefulness to the [[WP:DPL]] project, since there are already redirects on these pages that are slipping through your queries. --[[User:JaGa|<b><span style="color:#990000;">Ja</span><span style="color:#000099;">Ga</span></b>]][[User_talk:JaGa|<span style="color:#000000; font-size:small;"><sup>talk</sup></span>]] 20:37, 18 April 2011 (UTC)
 
OK, here's the new query:
<syntaxhighlight lang="sql">SELECT art.page_title AS title,
art.page_len AS len
FROM page AS art
JOIN categorylinks ON art.page_id = cl_from
JOIN pagelinks ON pl_title = art.page_title
AND art.page_namespace = 0
AND art.page_is_redirect = 0
AND pl_namespace = 0
JOIN page AS src ON src.page_id = pl_from
AND src.page_namespace = 0
AND src.page_title REGEXP '^List_of_mathematics_articles'
AND cl_to = 'All_articles_proposed_for_deletion'
 
UNION
 
SELECT art.page_title AS title,
art.page_len AS len
FROM page AS art
JOIN categorylinks ON art.page_id = cl_from
JOIN redirect AS red ON art.page_title = red.rd_title
AND art.page_namespace = 0
JOIN page AS r ON r.page_id = red.rd_from
AND red.rd_namespace = 0
JOIN pagelinks ON pl_title = r.page_title
AND r.page_namespace = 0
AND r.page_is_redirect = 1
AND pl_namespace = 0
JOIN page AS src ON src.page_id = pl_from

AND src.page_title REGEXP '^List_of_mathematics_articles'
AND cl_to = 'All_articles_proposed_for_deletion'
 
GROUP BY title
ORDER BY len ASC;
</syntaxhighlight>
It looks like a lot of changes, but there's really little to it. I'd be happy to rewrite all your queries if that would help. Also, I'd recommend you use queries like this regardless of whether you decide to support [[WP:INTDABLINK]] or not; as it stands, the many redirects already on the bot-maintained pages slip through the original query. --[[User:JaGa|<b><span style="color:#990000;">Ja</span><span style="color:#000099;">Ga</span></b>]][[User_talk:JaGa|<span style="color:#000000; font-size:small;"><sup>talk</sup></span>]] 06:51, 20 April 2011 (UTC)
 
The reason that redirects such as [[Mann's theorem]] are on the list is because the redirect pages themselves are categorized; see [http://en.wikipedia.org/w/index.php?title=Mann%27s_theorem&redirect=no]. Provided that each page is categorized correctly, the redirects that appear on the list are exactly the redirects that should be there. On the other hand, redirects that are not categorized won't be added to the list by the bot. &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 11:25, 8 May 2011 (UTC)

Mathbot seems to be glitching now for titles with parentheses in them. It replaces them with random numbers, causing the articles to display as red links. Any ideas why?

== Colors of animation for Heat Equation article ==
 
Oleg, hello. I was just doing some minor proofreading fixes to the Heat Equation article, when I noticed that your nice animation is actually showing a 2D system, and that the caption for the animation did not match the system being simulated. I made some changes to the caption, which I think now better explains what is going on.
 
Along the way I realized that in the animation right now green=hot and red=cold. This is opposite to the more usual coloring, where red typically means hot. The pictures would be easier for a beginner to understand, I think, if that assignment of colors could be changed, maybe using blue for cold, red for hot.
 
I see your Matlab code to generate the pictures. I would try to change the coloring myself, but I don't have Matlab. So I was wondering how you might feel about making that change and re-uploading the animation -- or maybe suggesting some way I could run Matlab online, or something like that.
 
Thank you.

==Can you redraw image?==
 
Hi! I see that on 16 July 2007 you did a revision for the colors in the image File:Kepler-first-law.svg [[File:Kepler-first-law.svg]]. I wonder if you could alter the image to make it more accurate. Right now the foci are drawn way too far apart from each other for the ellipse shown. This can easily be seen by looking at the point at the top of the minor axis: the sum of its distances to the two alleged foci is obviously much greater than twice the semi-major axis. Could you move both foci so that each one is at least twice as close to the center as they are now? Thanks very much!

:: Surprisingly enough, the image is correct. I measured the distances in Inkscape. The equation of an ellipse is <math>x^2/a^2 + y^2/b^2 = 1.</math> In this picture <math>a = 120,\ b = 84.</math> Then the distance from the center of symmetry of the ellipse to any of the two focii is <math>\sqrt{a^2-b^2} = 86.</math> What I measured was 84 or so. So all it takes is a little squashing of an ellipse for its focii to diverge a lot. [[User:Oleg Alexandrov|Oleg Alexandrov]] ([[User talk:Oleg Alexandrov#top|talk]]) 03:39, 28 April 2011 (UTC)
 
:::Thanks for looking into it -- you're right. Now I've used a ruler to measure the sum of distances to the foci from the top of the minor axis, and it does indeed equal twice the semi-major axis. It really doesn't look that way to me -- if you take the segment from the sun to the top of the minor axis, and slide its right endpoint down to the center while sliding its left endpoint to the left, it looks to me like the left endpoint ends up well outside the ellipse; but that's not true.

I like the suggestion of creating a separate list of mathematics disambiguation pages, but I don't think it should be maintained manually. If necessary, it can be moved into the [[WP:WPM]] project namespace. Since these lists are important for the day-to-day functioning of [[WP:WPM]], I think the {{tl|nobots}} templates should be removed, the other edits that you made reverted, and we should instead try to pursue a mutually satisfactory solution. I don't think dab links need to be ''urgently'' removed, especially not at the expense of productive areas of the project, even if they are technically not permitted under the Manual of Style.

:::::The bot does not worry about nobots on these pages anyway. Nobots is for bots that go around finding pages to edit. This bot is explicitly supposed to edit these list pages, and the pages are supposed to be edited by the bot, so it's somewhat meaningless to use a nobots tag here, and the bot has never implemented any detecton of the tag (the entire nobots system is optional for bots). The bot was not designed to ''remove'' the nobots tag, either, but because it was put at the bottom of the page the bot will probably remove it the next time it runs, just as the bot would remove any other stray wikitext put in there. &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 12:35, 9 May 2011 (UTC)

The main points here are:
* These lists are a case where we do want to link directly to some disambiguation pages. The MOS page about it does not prohibit all links whatsoever; the box at the top of that page explicitly says there will be exceptions.
* These lists and the bot go hand in hand. The bot has never followed the "nobots" thing, which is always optional for bots to implement. The bot will continue to update the lists. It has been updating the lists for years, and the lists are intended to be updated by the bot, not to be "cleaned up" at whim. The bot will remove stray wikitext from the bottom of the lists when it edits them; categories, templates, and such have to go near the top to remain in the list. Again, these lists are meant to be edited by the bot. The bot is designed to accept it if someone manually adds a new item to the list, but it will clean up many other manual edits as a side-effect of updating the list.
* If these pages bother you or confuse one of your tools, please simply filter them out of your tool. This cannot be very hard in any programming language. &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 12:18, 9 May 2011 (UTC)
 
Now let me point out the ''reason'' that we normally don't link to dismbiguation pages is that we want readers to go somewhere useful when they click a link when reading an article. That reason ''does not apply'' to this list: readers are not looking for the meaning of a word, they are expecting to go to a page that has a category marking it as a mathematics article. The organization of the list is that it contains redirects only if those redirects are themselves categorized as mathematics articles (and some are). Otherwise, the list simply links directly to the page, be it an article, list, disambiguation page, etc.
 
Because of the manual additions of pages like [http://en.wikipedia.org/w/index.php?title=A_posteriori_probability_%28disambiguation%29&redirect=no], someone will have to manually remove these from the list. Because they are not categorized as math articles, they are should not be listed (the bot tries to keep manually-added articles on the theory that people will add articles that the bot misses for some exceptional reason). On the other hand, the reason that [[A_posteriori_probability]] is added by the bot is that it is categorized in the "Applied statistics" and "Statistical terminology" categories, both of which are in the [[List of mathematics categories]]. As long a page is in any of those categories, it should be listed on the list of mathematics articles. &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 12:51, 9 May 2011 (UTC)
:I think part of the problem here arises from disambiguation choices. [[A posteriori probability]] is at least a [[WP:TWODABS]] situation and likely should not exist as a disambiguation page at all on that basis alone. If a page addresses different but related uses of mathematical terminology, as it appears many of these pages do, then it likely should be an article on the term per [[WP:DABCONCEPT]], and not a disambiguation page. On the other hand, I wonder why, for example, the list for "U" includes [[Unification]], which has no math terminology tag on the page (I guess maybe it had one in the past).
:I am well aware of the reason why we don't normally link to disambiguation pages, but nevertheless the encyclopedia contains [[Wikipedia:Disambiguation pages with links/The Daily Disambig|hundreds of thousands of these bad links]], and the number swells each day, only to be beaten back by a very hard-working crew of disambiguators. The job of fixing those links is complicated by intentional links, and although I can ignore these pages in my searches, they can not be filtered from the "what links here" page for the general disambiguator. I still do not see why these lists can not just use "foo (disambiguation)" redirects. I also see no reason why this bot can not be taught to ignore disambig links, or to post them up with a pipe through the disambig redirect, or to collect disambig links on a separate page (since they are not, in fact, actual articles ''about'' anything). If none of these options are available, we could simply move all of these disambig pages to their "Foo (disambiguation)" titles. That would also run against the MOS, but at least it would do so in a way that makes fixing errant links easier. I see from the discussion at the top of this page that I am not the first disambiguator to address this problem, and surely there will be others after me - let's find a solution that keeps it from generating this circular dilemma.

::I would not mind moving them to the "(disambiguation)" titles as a compromise. I would also be happy to go through the list of them manually and remove any, like [[Unification]], that should not be there any more.
 
::The reason that we cannot use "Foo (disambiguation)" links is that then we would not have the right links in the pagelinks table ("what links here"). What we want is this:
:::* Every article categorized as math is linked to directly from the list
:::* Other articles are not linked to directly from the list
 
::This is necessary, for example, for the "RecentChangesLinked" ("Related changes") tool to work correctly. That tool does not bypass redirects. For example, this page [http://en.wikipedia.org/wiki/Special:RecentChangesLinked/User:CBM/Sandbox] does not show the edit I made to [[Unification]] just now, because the page that is being used ([[User:CBM/Sandbox]]) does not link directly to the edited page. Compare [http://en.wikipedia.org/wiki/Special:RecentChangesLinked/Unification_%28disambiguation%29].
 
::I think that the best solution (apart from cleaning up any outdated entries in the lists) would be to educate disambiguators that the lists of mathematics articles are not like ordinary articles and are an exception to the general principle not to link to disambiguation pages. The MOS makes it clear that there are exceptions. &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 15:14, 9 May 2011 (UTC)
::: Unfortunately, disambiguators - like most Wikipedians - are not a monolithic group, and intermitant or incoming participants in that project would require constant "reeducation". That's why I am here having this discussion now, having come here unaware that this dispute had been raised before by others. Having thought it over, I now think the best solution for all would be to generally move these pages to their "Foo (disambiguation)" titles. It will be far easier to educate the much smaller group of people who attend to malplaced disambig pages, and to instruct the bots that generate those lists to ignore {{tl|mathdab}} pages. However, I would also suggest taking a very careful look at these pages and determining what terms are really "ambiguous" and what are really just variations of the same concept, or could be handled in other ways. For example, a page like [[Carathéodory's theorem]] need not be a disambig at all; it could changed into a short article at [[List of theorems associated with Constantin Carathéodory]], providing a bit more context as to each item on the list; or it could redirect to [[Constantin Carathéodory#Works]], which already duplicates the list currently found on the disambig page. There is probably a great deal that could be done to whittle down the collection to those terms which are truly ambiguous in the sense of the same word or phrase referring to completely unrelated concepts.

::::Actually, I somewhat like the idea of making things like [[Carathéodory's theorem]] into lists, but I know there are concerns with notability and with maintenance. The advantage of disambiguation pages is that they are easy to keep pruned and there are no notability concerns.
 
::::In the short term, though, I think that renaming them would solve the problem. And if we do it manually, it will give people a chance to check which of these disambig pages should still be listed on the list of math articles in the first place. Do you have a sense of how many there are? &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 19:33, 9 May 2011 (UTC)
::::: There are 260 articles with the {{tl|mathdab}} tag, which is probably a good place to start. Also, non-notable information should definitely not be in disambig pages any more than it should be in any other articles. In fact, there should be nothing on a disambig page that is not either an article itself, or discussed in an article.

I think the root problem here is that these lists are maintenance pages doubling as articles. Is there a reason (other than the amount of work involved in setting it up) that these two functions could not be separated? That is, the maintenance pages (more-or-less in their current form) going in the Wikipedia namespace, and the current location being occupied by list articles that do not have hidden talk page links or direct links to disambiguation pages without "(disambiguation)". Nobody would worry about the links to disambiguation pages if they weren't in article namespace (though neither JaGa nor BD2412 seems to have made this very clear). --[[User:Zundark|Zundark]] ([[User talk:Zundark|talk]]) 16:13, 9 May 2011 (UTC)
: That is also correct. We are unconcerned with links in project space, and many projects do maintain lists like these in project space rather than article space. That would definitely solve the problem from the perspective of the disambiguator.

::Project space would be good.

:::Using the "(disambiguation)" titles would be a compromise to help the people who are confused by the fact that these lists are supposed to link to dab pages. The problem is not the lists being in mainspace; they have been there since at least 2004 (in different locations) and are useful for browsing articles by title, not just for maintenance. The issue is editors who have a inner need to remove links to dab pages even when those links are intentional and appropriate. Now there is no universal policy against linking to dab pages; the MOS page on it even says there will be times when it is desired. But I willing to moving some dab pages to have the word "disambiguation" in their title, thus making use of an exception to a different MOS page, if that makes things easier for people who want to blindly replace links to dab pages. &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 23:54, 9 May 2011 (UTC)
:::: That these lists have been in mainspace for so long doesn't mean they belong there. You could, with no more effort than adding an additional instruction for the bot, maintain two sets of lists, one in mainspace listing only unambiguous titles of substantive articles, and one in project space indiscriminately listing everything in any math category for maintenance purposes. Regarding the "inner need to remove links to dab pages", this is a function of the need to parse through a thicket of hundreds of thousands of errant links that do require fixing. If we didn't have editors constantly making bad links, it would be less of a concern - and even {{tl|mathdab}} pages do have a collection of bad links made to them.

:::::I suppose that in principle we could maintain five lists. But there's no reason to do that; the lists themselves are fine. The difficulty here is entirely with the perceived difficulty for people who remove links to dab pages.
 
:::::Here is a question: the MOS makes it clear that there are exceptions (such as these pages) to the general principle not to link to dab pages directly. Is there no way that you keep track of pages that are intentionally linking to disambiguation pages other than to force those pages to be named "disambiguation"? The problem here seems to be that the MOS on linking to dab pages assumes it is acceptable to link to redirects, which it isn't for these lists. It seems easier to me to simply realize that these pages are exceptions to the general rule (as the MOS explicitly says there will be). &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 02:00, 10 May 2011 (UTC)
:::::: The MOS acknowledges that there will be instances when it is correct to link intentionally to a disambig page; it also says ''how'' to do this. Disambiguators use a wide variety of tools, but the most common is simply clicking on the "what links here" button to see what links are coming into a particular page. Do you have any particular objection to having two sets of lists? I'd be glad to copy them over to project space and cull the disambig links from the lists in article space.

:::::::: Linking to a redirect is not the same as linking to the dab page, and sometimes it is actually necessary to link to the dab page, in order to get that link into "what links here" to make the related changes tool work. How do you propose that people who edit disambig links should handle these exceptions?
 
:::::::: Nobody can simply move the lists to project space; the bot also needs to be updated, or it will simply recreate them in the present locations. People at the math project are also discussing moving the lists to project space (and updating the bot). But it seems like a pity to me to do that simply to make it easier for some people to edit disambig links without thinking about what they are doing, which seems to be the main justification for doing it. It's not hard to simply ignore these lists when replacing dab links. &mdash;&nbsp;Carl <small>([[User:CBM|CBM]]&nbsp;·&nbsp;[[User talk:CBM|talk]])</small> 11:00, 10 May 2011 (UTC)
::::::::: There is no need to insult disambiguators by suggesting that its "a pity" that we are trying to edit "without thinking about" what we are doing. We are only trying to improve the encyclopedia by attacking an endemic pattern of errors. Wikipedia has bots that remove vandal additions of vulgar terms from articles without "thinking" about it, and the bot at issue in this discussion is inidiscriminately adding links to lists without "thinking" about it; making it possible to automate or semi-automate processes to the greatest degree possible is a logical and beneficial trajectory for the encyclopedia. We have not encountered a problem like this with any other wikiproject, despite the widespread use of maintenence bots in this fashion, so clearly it is possible to use bots to maintain lists without making direct links to disambiguation pages in article space.

As I see it, the main purpose of the [[list of mathematics articles]] is browsing. Navigating is at most a secondary purpose. When you're browsing you're not looking for some particular thing; you're trying to find things you don't expect to find. If you didn't know that [[Xology]] is a concept with six distinct meanings in mathematics, each with its own article, then you would find out when you come across it in the [[list of mathematics articles]] and click on it. People who are browsing would be deprived of that opportunity if disambiguation pages were not listed there.

:This can be accommodated with [[WP:INTDABLINK]].

== need help with Random Matrix article ==
 
Hi Oleg,
 
I need some general advise if that's OK. I have tried to make
a major revision in the [[random matrix]] article, which was a BIG MESS
(a mixture of serious things and ref-s to some articles which
appeared on arxiv a month ago, in the style of ''applications
to radio transmitting on high frequency''). I rewrote it
completely, but, unfortunately, it seems that I have offended
several users who made previous contributions (though I tried
to add an explanation on the comments page both before and
after I made the changes, and also on their personal talk
pages suggesting a more serious discussion). So now the article
is an even bigger mess (the new version into which arbitrary
pieces of the old one have been inserted in arbitrary order).
 
Is there a standard wiki-way to manage a discussion about a major
revision? If there is a procedure of this kind, I think it
would also be great if an administrator would supervise it
for a while (e.g. check that the revision is not too aggressive,
and also to keep some order). I would also be grateful for any
general advise (on how to make major revisions in "popular"
articles without creating an even bigger mess).
 
Thank you very much!

: You may need to do some thorough work, such as checking which pages link to the lists, looking at redirects, etc. And I believe they have to be real page moves, rather than copy&paste. Once you are done, let me know. It won't be much work on bot's side.

== About a the merge proposal Hartogs'lemma -> Hartogs' extension theorem' ==
 
Hi Oleg. I am writing you since I would like to start the merging of the entry "[[Hartogs' lemma]]" into the entry "[[Hartogs' extension theorem]]", as proposed by the [[User:Set theorist|Set theorist]] ([[User talk:Set theorist|talk]]). I discussed the matter in the [[Talk:Hartogs' extension theorem|talk page]] of the target entry, and also I discussed the matter with [[User talk:Charles Matthews|Charles Matthews]] on his [[User talk:Charles Matthews|talk page]], who was the creator of the former one: he agrees on the merge (he also note that the exposition should be improved. :D ) and I produced evidence that the two topics dealt coincide. Is [[WP:Merge]] the only guideline I must follow or is there a need for an administrator, in order to do operations not described there? Thank you very much for your help.

== A question about wikilinks in the "See also" section of an entry ==
 
Hi Oleg, that's me again. This time I have a question about the wikilinks which can be included in the section "See also". Recently an editor has removed several meaningful wikilinks from that section of the entry [[Francesco Faà di Bruno]] motivating it by saying "wlink already included in the main article": I tried to find a style motivation on the [[WP:MOS]] but I did not find anyting. Is this a rule of style in [[Wikipedia]]? It seems strange to me such a way of including or not wlinks: if this were a rule, the link "[[Sobolev space]]" should not be placed in the "See also" section of the entry "[[Sergey Sobolev]], therefore a visitor willing only to search a reference to the results of Sobolev in the entry, without reading it will be disappointed. [[User:Daniele.tampieri|Daniele.tampieri]] ([[User talk:Daniele.tampieri|talk]]) 17:59, 29 June 2011 (UTC)
: I think that editor is right. But I am not sure if this is a strong policy. If you feel some links are important enough to be included in "see also" even if they are in the main article anyway then I guess it is OK to add them. [[User:Oleg Alexandrov|Oleg Alexandrov]] ([[User talk:Oleg Alexandrov#top|talk]]) 18:24, 29 June 2011 (UTC)
::Personally, I do not see the value of that rule. I would revert the deletion of a link from "See also" if the link in the main text is not readily apparent, for example, if the link in the main text were <nowiki>[[Sobolev embedding theorem|his work on weak derivatives]]</nowiki>.

== LaTeX to wiki translation preview not working ==
 
Hi Oleg I tried the [[User:Jmath666/latex2wiki|LaTeX to wiki translation tool]] we worked on few years back. Your preview script still submits the page to Wikipedia but it gets instantly deleted. I tried to change the page name to subpage in my user space but it still gets deleted. I think it was deleted before also but it would show the wikicode; now it does not do even that. Any ideas? Thanks! [[User:Jmath666|Jmath666]] ([[User talk:Jmath666|talk]]) 05:49, 15 August 2011 (UTC)
: Uh. Try looking at the logic in the functions named print_head nad print_foot in [http://en.wikipedia.org/wiki/User:Jmath666/latex2wiki.pl the source code] of your script. I tried to emulate there how a redlinked Wikipedia page would look like, to bootstrap its preview function. Compare that html code there with the html code of an [http://en.wikipedia.org/w/index.php?title=dummy_red_link_page&action=edit&redlink=1 actual redlinked page]. Perhaps the html format changed in the meantime.

* [[:Category:Rotation in three dimensions]]
(I added [[:Category:Applied mathematics]], so maybe it will now get added to the list.) I don't recall whether it's your bot or Jitse's that handles this.

== EOM ==
 
Hi,
 
I have a stupid question, perhaps you know the answer or you could direct me to someone who knows it. Once there was a template "eom" for Encyclopaedia of math. Apparently, today it was moved to SpringerEOM. For some reason, it was done in such a way that
 
{{eom|id=A/a010030|title=A posteriori distribution}}
 
appears instead of
 
{{SpringerEOM|id=A/a010030|title=A posteriori distribution}}
 
So the questions are:
 
* does this look like a bug or a feature?
* if the former, whom should I ask to fix it?
* if the latter, is there a nice bot owner whom I could ask to fix all the places where the old template was used?
 
Thank you very much,
[[User:Sodin|Sasha]] ([[User talk:Sodin|talk]]) 00:03, 8 September 2011 (UTC)
 
:PS I think I see the problem. Someone moved Template:eom to SpringerEOM (rather than Template:SpringerEOM), and apparently I do not have the permissions to fix this.

== Advice on two probable cases of self-promotion ==
 
Hi, Oleg. I'm writing you again to ask for an advice regard two edits that appear self promotion (at least to me):
#[[User:Mohsen.soltanifar|Mohsen.soltanifar]] has added a section on the "[[Bounded variation]]" entry just to describe his work and place a reference to an undergraduate paper written by him. This would be good if the contents of the paper (his work) were of some scientific interest: however, the actual "[[Bounded variation#Algebraic Operations with BV Functions|Algebraic Operations with BV Functions]]" section is a (fortunately short) mere collection of trivial facts: the space of ''BV'' functions is a [[vector space]], therefore is closed under subtraction and addition, and is an algebra as already stated in the Wikipedia article, therefore is also closed under multiplication. The quotient of two functions of such space could not belong to the same space, as the trivial example <math>1</math> ∈ ''BV''([<math>-1</math>,<math>1</math>]) and <math>x</math> ∈ ''BV''([<math>-1</math>,<math>1</math>]), and also the closure under composition is trivially false. I'd like to straightly remove it, but I would like to listen to your advice since you are surely more used than me to such matters. It is also interesting to note that this user's contributions all aim to promote his papers published in various undergraduate research journals, as I personally checked.
#[[User:Shazux|Shazux]] has added a short statement and a reference to a paper to the "[[Stefan problem]]" entry: I moved it in the separate section "[[Stefan problem#Applications|Applications]]" (created for this purpose). His statement is ambiguous, but since the work he refers to is published by the [[Begell House]] which is a publisher very active in the field of heat transfer theory, I would like to give him a chance to explain it by contacting him at his talk page. Am I doing the right thing?

==New AfD Template==
Hi Oleg, so after over a week, the response to the idea of having a new AfD template added to all new AfD pages have been a bit minimal.

== math article classification ==
 
Peace be with you, Oleg,
Thanks for welcoming me years ago... possibly I said that earlier. I started '[[synergetics coordinates]],' and I am pretty sure you helped me on it. The place I read about them, listed on the talk page, defines polysign numbers, i.e. numbers in which one axis is positive, and the two others that go from the origin through the vertices of a regular triangle each have a different sign: negative, and half-positive/half-negative. I would like to start or request an article, but I do not know how to classify this in WikiProject Mathematics. Do you know, or know where to ask? I used to be pretty skeptical about the numbers, and though they can be converted to Cartesian coordinates, I guess with those three axes there really must be three signs.

== Possible Mathbot bug at AfD ==
 
See [[Wikipedia_talk:Articles_for_deletion#Deletion_discussions_not_transcluded_to_this_page]]. Apparently, the bot failed to recognize an open AfD from a month ago, leading to the discussion still being open over a month it was started. You might want to take a look at this. Also, if one slipped through the cracks here, it's possible others even older might have, so it might be worth figuring out a way to check all AfDs to locate any others that have slipped through in a similar fashion.

== MSU Interview ==
 
Dear Oleg Alexandrov,
 
My name is Jonathan Obar [[user:Jaobar]], I'm a professor in the College of Communication Arts and Sciences at Michigan State University and a Teaching Fellow with the Wikimedia Foundation's Education Program. This semester I've been running a little experiment at MSU, a class where we teach students about becoming Wikipedia administrators. Not a lot is known about your community, and our students (who are fascinated by wiki-culture by the way!) want to learn how you do what you do, and why you do it. A while back I proposed this idea (the class) to the community[[Wikipedia:Village_pump_(proposals)/Archive_82#Learn_to_be_a_Wikipedia_Administrator_-_New_class_at_MSU|HERE]], where it was met mainly with positive feedback. Anyhow, I'd like my students to speak with a few administrators to get a sense of admin experiences, training, motivations, likes, dislikes, etc. We were wondering if you'd be interested in speaking with one of our students.
 
 
So a few things about the interviews:
* Interviews will last between 15 and 30 minutes.
* Interviews can be conducted over skype (preferred), IRC or email. (You choose the form of communication based upon your comfort level, time, etc.)
* All interviews will be completely anonymous, meaning that you (real name and/or pseudonym) will never be identified in any of our materials, unless you give the interviewer permission to do so.
* All interviews will be completely voluntary. You are under no obligation to say yes to an interview, and can say no and stop or leave the interview at any time.
* The entire interview process is being overseen by MSU's institutional review board (ethics review). This means that all questions have been approved by the university and all students have been trained how to conduct interviews ethically and properly.
 
 
Bottom line is that we really need your help, and would really appreciate the opportunity to speak with you. If interested, please send me an email at obar@msu.edu (to maintain anonymity) and I will add your name to my offline contact list. If you feel comfortable doing so, you can post your name[[User:Jaobar/Admins_to_Interview_List_1|HERE]] instead.
 
If you have questions or concerns at any time, feel free to email me at obar@msu.edu. I will be more than happy to speak with you.
 
Thanks in advance for your help. We have a lot to learn from you.
 
Sincerely,

If you need financial assistance or help with visa or hotel, then please register by May 1st and mention it in [https://wmberlin.eventbrite.com/ the registration form].
 
This is the premier event for the MediaWiki and Wikimedia technical community. We'll be hacking, designing, teaching, and socialising, primarily talking about [[mw:ResourceLoader|ResourceLoader]] and Gadgets ([[mw:Gadget kitchen|extending functionality with JavaScript]]), the switch to [[mw:Lua scripting|Lua for templates]], [https://meta.wikimedia.org/wiki/Wikidata Wikidata], and [[mw:Wikimedia Labs|Wikimedia Labs]].
 
We want to bring 100-150 people together, including lots of people who have not attended such events before. User scripts, gadgets, API use, Toolserver, Wikimedia Labs, mobile, structured data, templates -- if you are into any of these things, we want you to come!
 
I also thought you might want to know about [[mw:MediaWiki developer meetings|other upcoming events]] where you can learn more about MediaWiki customization and development, how to best use the [[mw:API|web API]] for bots, and various upcoming features and changes. We'd love to have power users, bot maintainers and writers, and template makers at these events so we can all learn from each other and chat about what needs doing.

== Vector potential ==
Hi Oleg, I was looking at the [[Vector potential]] article, and found it quite misleading. The reality is very simple, is it not, that if div(F) = 0 and F is defined on all of R^3, then F has a vector potential. No decay conditions required. Shouldn't this be the primary thing the article says? Maybe we should start changing it in that direction. Thanks, [[User:Kier07|Kier07]] ([[User talk:Kier07|talk]]) 15:12, 8 August 2012 (UTC)
: I think the assumption of decay comes in when you start proving that F has a vector potential.

[[User:Oleg Alexandrov|Oleg Alexandrov]] ([[User talk:Oleg Alexandrov#top|talk]]) 16:09, 8 August 2012 (UTC)
: I'm no expert, but I'm pretty sure decay conditions aren't necessary for the existence of a vector potential. Only that particular choice may not work if you don't have enough decay...

== [[Christmas in the Park (San Jose)]] ==
 
Hi! I notice you have been around here a long time and have made many valuable contributions in the field of math. Thanks for your contributions. Writing about social things is very different than writing about science. Notability for articles on places, things and events is established by citing third-party references such as newspapers, magazines and books. Basically, the standards are that the world has to have noticed it before it can be in Wikipedia. I looked in the category "Christmas" and there are no articles whatsoever on Christmas festivals. I am guessing these are covered in the article on the settlement in which they occur. My suggestion to you would be to look for some references of the type I have mentioned above. There is a large Christmas festival in Wabash, Indiana that I know has been covered in the AAA magazine for Michigan, ''Michigan Living''. If you could find any coverage like that, from away from the SF/SJ area, that would go a long way toward showing notability.
 
Secondly, your argument at the AfD is not at all an effective one. See[[WP:OTHERSTUFFEXISTS]]. I think we put way too much emphasis on Pokemon and the like, too. But, like it or not, things like that have their own notability standard. Schools, or at least high schools, are considered definitively notable. There are many arguments for that, mostly centering on the percentage of time in one's life that is spent there. An effective argument would be based in policy, or using defense of your sources.
 
I hope you can find more and more appropriate sources for your article. I will look too. But, I have to say, I wouldn't have nominated the article if I thought there was much hope of that.

== Great Circle-distance formula is missing the radius ==
 
Greetings,
 
hmmmm, I see what you mean about citing a unit sphere.
 
For a consistent article, is it more appropriate to drop the "r" from the following equation since it equals one too?
 
d = r \Delta\widehat{\sigma}.\,\!
 
That gives d = the central angle in radians.
 
I think people would find the article more useable in the general case.
 
By the way, I am new to editing Wikipedia pages.
On reflection, is there a strategy to leaving mistakes in web pages to force people to think about what they are using?
Trip up students?
Give a learning experience to the unwary?

==Note on Mathbot AfD process==
I noticed that Mathbot wasn't removing one of the AfD listings for 8 September, even though it was closed. After checking further, the nominator erroneously made a "2nd nomination" page for the request, then after noticing this, redirected it back to the standard nomination page. Apparently, Mathbot didn't notice the redirection and thought the discussion was still open. Bypassing the redirect fixed the problem [https://en.wikipedia.org/w/index.php?title=Wikipedia:Articles_for_deletion/Log/2013_September_8&diff=prev&oldid=573948683]. That would come up so rarely that I doubt it would be worth fixing, but thought you might want to know in case it ever comes up.

You are right, I see what you mean. I think the confusion is that the other pictures on the Wikipedia page are using optimal step sizes, and so show search directions which are orthogonal. Perhaps the captions could be changed to add something along the lines of "using optimal step length" or "using fixed or non-optimal step length"? <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/108.168.65.229|108.168.65.229]] ([[User talk:108.168.65.229|talk]]) 23:12, 23 October 2013 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->
 
== Seeking a Lift of my Permanent Block, Can You Help ==
 
Hi, Mr Alexandrov, I am looking for an administrator with the time and thoughtfulness to look into my claim that I am wrongly blocked for sockpuppetry. I decided to ask an administrator with username beginning "O" and come to you secondly after "Orlady" who turned me down. I was no-warn/no-diffs/no-discussion blocked in May 2012 by Timotheus Canens who only clicked his Twinkle or Pop-Ups button that generated an hyperlink to WP:SOCK. I am a long-time Wikipedia editor (since 2005 or 2006) who has authored several articles and substantially contributed to many more. Early last year I switched to a new account for privacy reasons. This is authorized by the policy WP:CLEANSTART. Timotheus used the fact that I had a prior account to accuse me of "socking." He mischaracterized "switched to new account and never went back" as "using alternate accounts abusively."
 
He never said much more than that but several people (five or six) from WP:AN/ANI descended on my talkpage to criticize me and make allegations against me. I didn't handle it well. I didn't know who was administrator, who was not. I was inexperienced in responding to blocking. I was a bit angered because I took "sock" as an attack on my honesty.
 
Orlady told me "no, I will not help you, you must convince him that blocked you." But Timotheus Canens will not speak to me and has never spoken to me. Plus I feel his or any no-warn/no-diffs/no-discussion block is obviously an abuse of his or any administrator's powers. It was done out of irritation and a click of his mouse button.
 
There is a lot more to the story. I can answer your questions and tell you what you need to know to make a just decision about unblocking. The best way that I know of to begin is if you unblock merely my talkpage, and we have a conversation. My talkpage was blocked to me by Spartaz after Beeblebrox whispered in his ear. Spartaz claimed I was using it as a "pulpit." That is a shaky rationale, also without warning, and talkpage blocks are supposed to be used for truly egregious behavior. I state that I will not mislead you. I certainly state that I never socked, I switched accounts, and never went back. You can see I told the truth about that in my first edit. I see, Mr. Alexandrov, that it is not the kind of thing you usually do, but that really makes you more suited to it in my mind than a WP:AN/ANI regular. You just need to learn about it and apply rules to evidence. Lastly I am "block evading" right now, by signing my username to a raw IP edit. I know that is against the rules but I feel I've no other way to proceed.

== Mathbot, Category Trees, Talk links on List of Mathematics Articles ==
 
* I really admire your work with Mathbot. Is it being used on other subjects besides Mathematics? I would like to learn more about it. I am mainly interested in classification, so your lists of articles and categories for mathematics are good material. I would like to run mathbot on other subjects. Is that possible?
* I have been looking at the category tree for [[:Category:Mathematics]] to see if it could be improved, and how. I added the category tree boxes at the top of that page, because I think that particular tool could make it easier to navigate. It is faster to scroll down the tree, opening categories where appropriate, than to click through all the individual category pages. That way there is only one main page for Category:Mathematics -- you never leave it. I have also tried a few parent trees, starting from the bottom, but that is in worse shape. A little work could make category trees a very useful tool for wikis. I would even go so far as to suggest that a better category tree could be placed on every article, and do away with category pages altogether.
:* I was trying to think of a way to automatically open a category tree for mathematics and trace the categories to a particular page - highlighting in red, for instance. Just a thought. Or start from an article and trace the way to mathematics.
* Visiting [[Wikipedia:WikiProject_Mathematics/List_of_mathematics_articles_(A)]], I looked at the html generated, and the edit source. I noticed that all the Talk: pages are there, but there is nothing to click on. I suppose this is intentional. Is there a way to turn on the talk links? A keyboard shortcut or click I am missing?

Greetings.
 
* The tool is not used on other projects. What exists however, is a cgi script, which make suggestions for which articles to add to a list. See [[Talk:List of numerical analysis topics]] for an example.
 
* You are welcome to use the tool on other subjects. It should be easy to tweak. The code is public. But note that the code is written in Perl which is not the most readable language (I would write it in python if I had to start from scratch). See [https://code.google.com/p/mathbot/ https://code.google.com/p/mathbot/]. You are welcome to use it.
 
* This tool requires supervision, in the form of dedicated users who examine its output and weed out articles categorized by mistake or borderline relevant ones.
 
* Regarding the links to the empty talk pages, there used to be some reason for that, something about tracking both articles and talk pages from the list of recent changes. I am not sure how relevant that is anymore.
 
:[[User:Oleg Alexandrov|Oleg Alexandrov]] ([[User talk:Oleg Alexandrov#top|talk]]) 06:38, 13 June 2014 (UTC)
 
::* I looked at the code, and it '''is''' hard to read. If I had to start from scratch, it seems to take the list of mathematics category pages, extract all the links to article talk & categories, maybe portal, maybe foreign wikis, maybe templates. If there are new categories or pages or namespaces, notify someone. Write the article names to the list of names (A-Z). Write the category names to the list of categories. Make the article names list available to the random page in subject tool. Make the category tree data available to others. Manually update the master lists according to human input.
::* The problem, for a new subject, it to build the original list of categories. That can be done automatically by doing a supervised search of the category tree for a main category from the top, and searching articles and categories for keywords in the subject. A few iterations and a pretty clean list comes out. I can do this manually now. I am trying to automate steps.
::* It is possible to do an exhaustive list of all the article and category links in all the category and article pages for a given starting list, (going inside each page and looking at all wikipedia links) then manually classify the resulting links to produce a category tree dataset that can be used for navigating. I have experimented with this a few times, and get decent results. I have manually classified 100,000 links to assign useful classes, but there are probably 30,000*40= 1,200,000 links in the mathematics pages. Many are duplicates, and most point within the core mathematics area, so maybe 100,000 links to classify? Just thinking...
::* What do you think of the [[Template:Category tree all]] examples at [[:Category:Mathematics]]? They are rough, but useful even now. I see opportunities to improve them.
::* I extracted the page and category links from the list of math articles A-Z and got 22673 articles, 19322 talks, and 1284 categories, not counting redlinks. I do not know how this matches with your numbers; but, if I write my own, we should be able to compare numbers at some point. I left out the 0-9 pages for now. The 0-9 yields 502 talk and 502 articles, some red links.

:::: The code is messy indeed. I have not been involved in any work involving categories or scripting for many years.

Hi,
 
I started a topic at [[Wikipedia_talk:Articles_for_deletion#August_30th_is_missing_from_lists_of_open_AFDs]] about August 30th being missing from [[Wikipedia:Articles for deletion/Old]] and [[Wikipedia:Articles for deletion/Old/Open AfDs]].

== Afd log and [[Template:Cent|Cent]] ==
 
I was curious why Mathbot adds {{tl|Cent}} to the new AfD log for each day. There's some discussion on streamlining [[Wikipedia_talk:Articles_for_deletion#Lighter_templates|transclusions on the page]] to reduce load times or avoid the transclusion limit and while cent is just a single transclusion on the page I'm not sure it is useful. Thanks. [[User:Protonk|Protonk]] ([[User talk:Protonk|talk]]) 15:15, 19 September 2014 (UTC)
 
* I usually check the daily AfD logs and this is the main way that I get to see those centralised discussions. If I didn't see them there, I'm not sure where I'd get to see them instead. So, while the connection between them isn't obvious, I'd oppose changing this without having a good alternative in place.

== Applied mathematics and mathematical physics ==
 
Hi, Oleg! As an applied mathematician, how do you see the relation between applied math and mathematical physics? Is there mathematical physics included in applied math?--[[Special:Contributions/5.15.185.216|5.15.185.216]] ([[User talk:5.15.185.216|talk]]) 21:59, 18 January 2015 (UTC)
 
== List of math red-links is out of date ==
 
Dear Oleg: Could you please have Mathbot update [[User:Mathbot/List of mathematical redlinks]]. {{user|Mark L MacDonald}} complained to me about it being out-of-date and thus having a large fraction of blue-links (and perhaps missing red-links). Mathbot appears to have last updated it in 2007. [[User:JRSpriggs|JRSpriggs]] ([[User talk:JRSpriggs|talk]]) 15:42, 6 March 2015 (UTC)
: JRSpriggs, yours is a valid request and I am glad the list is still being considered helpful. That being said, the amount of metaphorical dust on that code and the amount of time with a rested mind that I have is such that probably it will take some while before I can revisit this issue.

== Bot question ==
 
Hi Oleg,
 
We haven't interacted in a while, but hopefully you still remember me.
 
A company I used to work for, SimilarWeb, is trying to get their bot accepted to Wikipedia, for displaying information from their analytics platform. So far they haven't managed to get it approved.
 
Is there any help or guidance you can give on this matter? I figured your experience with Mathbot would be handy.

== Nice catch at The Revenant before the week-end. ==
 
Thanks for your good catch at the film article for The Revenant. Another editor also tried to change the Pawnee Indians, which you corrected, to another tribe which appears in the book version but not in the film version which identifies the Pawnee Indians in the captions included in the film. I fixed it again this morning to your correct version.
 
I orignially wrote the short Plot summary there before the week-end to get things started. It seemed to get alot of good responses. By this morning, however, I found that the article appeared to have been tag bombed, and the Plot section expanded to almost two times the MoS recommended length of 700 words. I spent a good deal of time on rewrites this morning and correcting the tag bombing issues, and I started a Talk page section for it as well. Can you offer a little help since the 35,000 daily page count is likely to get much, much higher when the general release of the film goes world-wide right after the New Year. May I request a short-term partial page protection for a two week period, only to get through the week of the big general release. I think its ok for regular editors but I don't think I will be able to keep up with all the unestablished accounts from the daily 35,000 page counts. If you prefer me to make the formal request for the page request then that's ok as well. Thanks for you edit on the "Pawnee Indians" from last week. Cheers.

== Extended confirmed protection ==
 
{{ivmbox|1=Hello, Oleg Alexandrov. This message is intended to notify administrators of important changes to the protection policy.
 
[[WP:BLUELOCK|Extended confirmed protection]] (also known as "30/500 protection") is a new level of page protection that only allows edits from accounts at least 30 days old and with 500 edits. The automatically assigned [[WP:EXTENDEDCONFIRMED|"extended confirmed" user right]] was created for this purpose. The protection level was created following [[Wikipedia:Village pump (proposals)/Archive 129#New usergroup with autopromotion to implement arbitration "30-500" bans as a page protection|this community discussion]] with the primary intention of enforcing various arbitration remedies that prohibited editors under the "30 days/500 edits" threshold to edit certain topic areas.
 
In July and August 2016, [[WP:ECP2016|a request for comment]] established consensus for community use of the new protection level. Administrators are authorized to apply extended confirmed protection to combat any form of disruption (e.g. vandalism, sock puppetry, edit warring, etc.) on any topic, subject to the following conditions:
* '''Extended confirmed protection may only be used in cases where semi-protection has proven ineffective'''. It should not be used as a first resort.
* '''A bot will post a notification at [[Wikipedia:Administrators' noticeboard]] of each use'''. MusikBot currently does this by updating [[User:MusikBot/ECPMonitor/Report|a report]], which is transcluded onto the noticeboard.
Please review [[Wikipedia:Protection policy#Extended confirmed protection|the protection policy]] carefully before using this new level of protection on pages. Thank you. <br><small>This message was sent to the administrators' [[Wikipedia:Administrators/Message list|mass message list]].

==Mathbot skipped days on AFD==
Hi!
 
I noticed that the days 26 October (Wednesday), 27 October (Thursday), and 28 October (Friday) were missing from the list of old articles for deletion. I looked at [[Wikipedia:Articles for deletion/Administrator instructions]] out of curiosity (I'm not an admin) due to the missing days on the Old AFD page. On that page, under the '''Closing out an AfD log page''' heading I clicked the "here" (http://tools.wikimedia.de/~mathbot/cgi-bin/wp/afd/afd.cgi) external link ("If all deletion discussions on an AfD log page have been closed, then please go to Wikipedia:Articles for deletion/Old and remove that AfD log page (which Mathbot can do automatically by clicking [http://tools.wikimedia.de/~mathbot/cgi-bin/wp/afd/afd.cgi here])" which ran [[User:Mathbot|Mathbot's]] script (although I wasn't aware that was what the link would do - sorry if I did anything wrong). It updated the number of open discussions for 25 October (Tuesday) - 18 October (Tuesday), and added 28 October (Friday) to the top of the Old discussions list and to this page: [[Wikipedia:Articles for deletion/Old/Open AfDs]], but skipped [[Wikipedia:Articles for deletion/Log/2016 October 27|27 October (Thursday)]] and [[Wikipedia:Articles for deletion/Log/2016 October 26|26 October (Wednesday)]], despite the fact that there are still open discussions from both of those days. I then tried clicking on the [http://tools.wmflabs.org/mathbot/cgi-bin/wp/afd/afd.cgi Refresh the number of open discussions] external link (http://tools.wmflabs.org/mathbot/cgi-bin/wp/afd/afd.cgi) on the [[Wikipedia:Articles for deletion/Old]] page, to see if it helped, but it did not.
 
I would add the missing days in manually, but the edit tab of [[Wikipedia:Articles for deletion/Old]] says "Admins: New days are added by Mathbot normally, and should NOT be added manually. Please don't remove the very last day when it has reached 0 open, as the format is specific and must be maintained." I am not an admin and don't want to mess anything up (further) but did want to bring the problem to someone's attention.
I just looked at Mathbot's contributions and it looks like there weren't any for November 3rd - 4th on AFD related pages. Note: I also posted this on the Old Articles for Deletion talk page before I realized this would be a better place to post it. Thanks! [[User:Scatter89|Scatter89]] ([[User talk:Scatter89|talk]]) 05:59, 5 November 2016 (UTC)
: Edited to add - I just looked at [[Wikipedia:Articles for deletion/Administrator instructions]] again on the Old AFD page. It says: "'''Closing out an AfD log page'''
Every day, the AfD log page (e.g. [[Wikipedia:Articles for deletion/Log/{{ #time: Y F j | -7 days }}]]) that is ''more'' than seven days old should be moved to [[Wikipedia:Articles for deletion/Old]] (currently, this is automatically done by [[User:Mathbot]]). With few exceptions (e.g., an AFD-nominated article that qualifies for [[Wikipedia:Speedy keep]] or deletion under [[WP:CSD]]), the decision to keep or delete a page is to be implemented only ''after'' this move has been performed.
If ''all'' deletion discussions on an AfD log page have been closed, then please go to [[Wikipedia:Articles for deletion/Old]] and remove that AfD log page (which Mathbot can do automatically by clicking [http://tools.wikimedia.de/~mathbot/cgi-bin/wp/afd/afd.cgi here]). Then, go to [[Wikipedia:Archived deletion discussions]] and paste that AfD log page at the top in the appropriate month (currently, this is also automatically done by Mathbot)."
However on the [[Wikipedia:Archived deletion discussions]] page, achieved discussions are listed under October 2016 for October 1 - 18, and then October 19 - 25 are not listed (they aren't missing; those days still have open discussions), and then October 26 and 27 are listed in list of archived deletion discussions despite having open discussions.) Odd. Hope that helps! [[User:Scatter89|Scatter89]] ([[User talk:Scatter89|talk]]) 06:47, 5 November 2016 (UTC)

: Thank you for letting me know. Last time I did not dig deep enough. The Tools server is being upgraded, and my dependencies needed to be rebuilt. Done now. I hope it works. [[User:Oleg Alexandrov|Oleg Alexandrov]] ([[User talk:Oleg Alexandrov#top|talk]]) 03:55, 12 November 2016 (UTC)
 
Is Mathbot down again? I'm trying to "Refresh the number of open [AFD] discussions", using this link [http://tools.wmflabs.org/mathbot/cgi-bin/wp/afd/afd.cgi], and I get an error.

: [[User:Natg 19|Natg 19]], thank you. The problem is due to the fact that the Tools web server runs an older version of Ubuntu than the main system. Unfortunately I spent quite some time on this and could not figure out how to connect to an old Ubuntu system that also has a compiler that would compile that dependency causing the error above. I will keep on digging. It may take up to a week as I have quite limited free time. Thank you for letting me know. [[User:Oleg Alexandrov|Oleg Alexandrov]] ([[User talk:Oleg Alexandrov#top|talk]]) 07:02, 29 November 2016 (UTC)
:: I could not make it work, due to the fact that I was unable to find an Ubuntu 12 development machine on the toolserver to compile the dependency. I'll have to turn off the cgi script. The bot will still run, I set it now to doing it every hour, but the user won't be able to click on the link to refresh the bot. This will be temporary. Per https://wikitech.wikimedia.org/wiki/Tools_Precise_deprecation in a few months all of the tools servers will run the newer Ubuntu, then I will bring back the link to the CGI script.

== Two-Factor Authentication now available for admins ==
 
Hello,
 
Please note that [[Time-based One-time Password Algorithm|TOTP]] based two-factor authentication is now available for all administrators. In light of the recent compromised accounts, you are encouraged to add this additional layer of security to your account. It may be enabled on your [[Special:Preferences|preferences page]] in the "User profile" tab under the "Basic information" section. For basic instructions on how to enable two-factor authentication, please see the [[Help:Two-factor authentication|developing help page]] for additional information. '''Important''': Be sure to record the two-factor authentication key and the single use keys. If you lose your two factor authentication and do not have the keys, it's possible that your account will not be recoverable. Furthermore, you are encouraged to utilize a unique password and two-factor authentication for the email account associated with your Wikimedia account. This measure will assist in safeguarding your account from malicious password resets. Comments, questions, and concerns may be directed to the [[Wikipedia:Administrators%27_noticeboard#Two-Factor_Authentication_now_available_for_admins|thread on the administrators' noticeboard]].

== A new user right for New Page Patrollers ==
 
Hi {{BASEPAGENAME}}.
 
A new user group, [[Wikipedia:New pages patrol/Reviewers|'''New Page Reviewer''']], has been created in a move to greatly improve the standard of new page patrolling. The user right can be granted by any admin at [[Wikipedia:Requests for permissions/New page reviewer|PERM]]. It is highly recommended that admins look beyond the simple numerical threshold and satisfy themselves that the candidates have the required skills of communication and an advanced knowledge of notability and deletion. Admins are automatically included in this user right.
 
It is anticipated that this user right will significantly reduce the work load of admins who patrol the performance of the patrollers. However,due to the complexity of the rollout, some rights may have been accorded that may later need to be withdrawn, so some help will still be needed to some extent when discovering wrongly applied deletion tags or inappropriate pages that escape the attention of less experienced reviewers, and above all, hasty and bitey tagging for maintenance. User warnings are available [[Wikipedia:New pages patrol/Templates|here]] but very often a friendly custom message works best.
 
If you have any questions about this user right, don't hesitate to join us at [[WT:NPR]]. <small>''(Sent to all admins)''</small>.[[User:MediaWiki message delivery|MediaWiki message delivery]] ([[User talk:MediaWiki message delivery|talk]]) 13:48, 15 November 2016 (UTC)

== Romanian history - aviator Constantin Cantacuzino ==
 
Oleg,
 
Did you know Cantacuzino rescued 1274 American prisoners of war held in Romania?
 
I decided to share this with you because just one day after editing the Wikipedia entry for Mr. Cantacuzino, I learned that you are my assigned contact on Wikipedia and that you are Romanian. So I thought you might be interested in this small piece of Romanian history. I realize how poorly the Wehrmacht treated its Romanian conscripts (e.g., using them as cannon fodder at the battle of Stalingrad. So it was nice to learn about Cantacuzino's valor.
 
https://en.m.wikipedia.org/wiki/Constantin_Cantacuzino_(aviator)
 
I edited the page by replacing what I felt was an irrelevant fact (how long it took to fly from Romania to Italy) with a more relevant fact (the number of American POWs rescued and the number and type of planes - B-17s - used to transport them out of Romania). I cited my source.

== Running on Beta ==
 
If if it's not too much trouble, could you configure MathBot to also do the 'Initializing a new AfD day' task on https://en.wikipedia.beta.wmflabs.org/ (same page names as production)? We do QA testing for PageTriage there before it hits production, and that would save a bit of time. [[User:Mattflaschen-WMF|Mattflaschen-WMF]] ([[User talk:Mattflaschen-WMF|talk]]) 00:03, 7 February 2017 (UTC)
: Done. You can see [https://en.wikipedia.beta.wmflabs.org/wiki/Special:Contributions/MathbotBeta the bot contribs]. Hopefully you will mirror the exact convention which already exists on this (non-beta) en.wikipedia, then the bot will simply do the same thing on beta as here. [[User:Oleg Alexandrov|Oleg Alexandrov]] ([[User talk:Oleg Alexandrov#top|talk]]) 05:55, 7 February 2017 (UTC)
::Thanks! I appreciate it. It does indeed use the same AfD page name conventions, and it should use all the same other conventions (there is on-wiki JS config which has to be manually synced currently). I won't ask you to do anything different on Beta. If we ran into an inconsistency, that would just indicate we need to re-sync some part of the Beta config or templates.

== Invitation to Admin confidence survey ==
 
Hello,
 
Beginning in September 2017, the Wikimedia Foundation Anti-harassment tool team will be conducting a survey to gauge how well tools, training, and information exists to assist English Wikipedia administrators in recognizing and mitigating things like sockpuppetry, vandalism, and harassment.
 
The survey should only take 5 minutes, and your individual response will not be made public. This survey will be integral for our team to determine how to better support administrators.
 
<big>To take the survey sign up '''[[en:Wikipedia:Community health initiative on English Wikipedia/Administrator confidence survey|here]]''' and we will send you a link to the form.</big>
 
We really appreciate your input!

== Possible merger candidate? ==
 
You are a major contributor to two articles:
* [[Unitary transformation]]
* [[Unitary operator]]
 
A reader contacted Wikimedia ([[ticket:2017072510014582]]) suggesting that there was enough overlap in material that these two article should be merged. Do you have thoughts on this proposal?--[[User:Sphilbrick|<span style="color:#000E2F;padding:0 4px;font-family: Copperplate Gothic Light">S Philbrick</span>]][[User talk:Sphilbrick|<span style=";padding:0 4px;color:# 000;font-family: Copperplate Gothic Light">(Talk)</span>]] 16:44, 10 October 2017 (UTC)
: [[User:Sphilbrick]], the standard way I recall of doing this kind of thing is to put a proposed merge note on top of the articles in question. I happen to think they should not be merged. It is true that a unitary operator is also a unitary transform, but unitary operators are a very important special case, much more studied than unitary transforms, from what I know, and with a lot more interesting properties. The analogy here would be between the article on cars, and the one on electric cars, for example. Certainly the latter deserves its own article.

I modified all these articles yesterday to add a DEFAULTSORT, so that they would list correctly in [[:Category:Mathematics-related lists]], but Mathbot has removed all those changes. Why? [[User:Colonies Chris|Colonies Chris]] ([[User talk:Colonies Chris|talk]]) 17:38, 21 September 2018 (UTC)
 
== Looking for Category expert help ==
 
Greetings Oleg Alexandrov, In addition to doing article assessments, I've been contributing input for daily ''WP 1.0 bot'' assessment processing.
 
There are on-going issues with the bot stalling, repeating WP deadlocks, not creating daily log files.
 
Details are at [[Wikipedia talk:Version 1.0 Editorial Team/Index#Conflicting project tags]].
 
Hoping you are able to help solve the complex issue of Conflicting project tags. Regards, [[User:JoeHebda|JoeHebda]] ([[User talk:JoeHebda|talk]]) 01:08, 24 October 2018 (UTC)

My guess is that the issue is the bot's password is less than 10 characters long, as the error when running the bot manually is "Error is: Can't log in in as Mathbot! Result was '1'." (the WMF recently changed the requirements for bot password lengths and deployed it on the [[WP:THURSDAY|Thursday]] December 20) [[User:Galobtter|Galobtter]] ([[User talk:Galobtter|pingó mió]]) 13:13, 24 December 2018 (UTC)

Hello Oleg Alexandrov,
 
I really liked your animated illustration of Snell's Law at https://commons.wikimedia.org/wiki/File:Snells_law_wavefronts.gif
 
Would it be possible to upload all the Matlab code for this? There seems to just be a fragment at https://commons.wikimedia.org/wiki/File:Snells_law_wavefronts.gif#Source_code
 
For instance you have uploaded Matlab source code for your related figure at https://commons.wikimedia.org/wiki/File:Spherical_wave2.gif

== [[User:Mathbot/Recent changes]] ==
This page is not about a critic of Judaism, but it is still in the category [[:Category:Critics of Judaism]] because the bot adds that category to that page.
 
It should handle categories differently: it should add <nowiki>[[:Category:Critics of Judaism]]</nowiki> and not <nowiki>[[Category:Critics of Judaism]]</nowiki>. That way, the page contains a link to the category instead of being in the category. --[[User:Hob Gadling|Hob Gadling]] ([[User talk:Hob Gadling|talk]]) 15:52, 3 April 2019 (UTC)

==Mathbot error page==
I'm receiving an error page on attempting to use Mathbot to refresh open AfD discussions. It returns a 503 with the following error text:
 
No webservice
 
The URI you have requested, /mathbot/cgi-bin/wp/afd/afd.cgi, is not currently serviced.
 
If you have reached this page from somewhere else...
This URI is part of the mathbot tool, maintained by Oleg Alexandrov .
 
That tool might not have a web interface, or it may currently be disabled.
 
If you're pretty sure this shouldn't be an error, you may wish to notify the tool's maintainers (above) about the error and how you ended up here.

== Administrator account security (Correction to Arbcom 2019 special circular) ==
 
ArbCom would like to apologise and correct our previous mass message in light of the response from the community.
 
Since November 2018, six administrator accounts have been compromised and temporarily desysopped. In an effort to help improve account security, our intention was to remind administrators of existing policies on account security — that they are [[Wikipedia:Administrators#Security|required]] to "have strong passwords and [[Wikipedia:Personal security practices|follow appropriate personal security practices]]." We have [[Special:Permalink/891851004#Return of permissions for compromised administrator accounts|updated]] our procedures to ensure that we enforce these policies more strictly in the future. The policies themselves have not changed. In particular, [[WP:2FA|two-factor authentication]] remains an ''optional'' means of adding extra security to your account. The choice not to enable 2FA will not be considered when deciding to restore sysop privileges to administrator accounts that were compromised.
 
We are sorry for the wording of our previous message, which did not accurately convey this, and deeply regret the tone in which it was delivered.

== [[Wikipedia:Articles for deletion/Old]] ==
 
Hi there. On [[Wikipedia:Articles for deletion/Old]], there is a handy [https://tools.wmflabs.org/mathbot/cgi-bin/wp/afd/afd.cgi link] that is supposed to trigger Mathbot to refresh the number of open AfDs listed on the page. However, clicking on that link only seems to bring up a page with a bunch of seemingly meaningless text, and does not trigger the bot to refresh the page outside of its hourly update schedule. Any idea what's caused that link to break? [[User:Scottywong|<span style="font:small-caps 1.2em Garamond,Times,serif;color:#772277;letter-spacing:0.2em;">‑Scottywong</span>]][[User talk:Scottywong|<span style="font:0.75em Verdana,Geneva,sans-serif;color:#777777;">|&nbsp;verbalize&nbsp;_</span>]] 02:19, 30 July 2019 (UTC)
: Howdy. This is discussed a couple of sections earlier. Basically the web server on which the cgi script runs when triggered by the user uses a different perl version than the sever on which this script runs on its own every hour. I cannot access the web server to debug this, and nobody seems willing to help. Hence I turned off the ability for the user to run the cgi script manually (and I also cleaned the meaningless text). Hence, one will have to wait for the bot to run each hour on its own. Sorry I can't be of more help.

# Move the articles to [[Wikipedia:WikiProject Mathematics/List of mathematicians (A)]], etc.
# Put them in a new category [[:Category:WikiProject Mathematics list of mathematicians]], which will be a subcategory of [[:Category:WikiProject Mathematics list of articles]]
# Use a sortkey of A, B, etc.

== Need new bot password for WP 1.0 Bot ==
 
Hello Oleg, I (along with {{u|Kelson}}) am the current maintainer of the WP 1.0 Bot. We've made a lot of progress with the bot over the past two years, but long story short: we need your help. I accidentally leaked the "bot password" of the bot on Github. I don't have access to the login password for the bot, but the bot password was revoked and we need to log in and create a new one. According to the discussion on [https://phabricator.wikimedia.org/T269513 this phabricator ticket], the bot's email address is your email. Can you help me login and create a new bot password? Thanks! [[User:Audiodude|audiodude]] ([[User talk:Audiodude|talk]]) 23:51, 8 December 2020 (UTC)
 
: I tried to reset my password, but I am not getting an email with instructions saying how I should reset it, and I waited at least 5 minutes. I don't even recall if I am still the owner of this account, so if it is my email address that figures on the record, as I passed on the responsibility for it a long time ago.
 
: Even if I was able to reset the password, I don't know how I can share that with you folks in a way which is safe and guaranteed to go to the right people.
 
: Can the Wikipedia system folks take care of this somehow? [[User:Oleg Alexandrov|Oleg Alexandrov]] ([[User talk:Oleg Alexandrov#top|talk]]) 00:16, 9 December 2020 (UTC)
 
:: Thanks for the quick reply, and for trying to reset the password. As stated on the [https://phabricator.wikimedia.org/T269513 Phabricator task], the email is a .edu email address, if that helps. I'm crafting a reply on Phabricator right now and will let you know if there's anything else you can do. Thanks! [[User:Audiodude|audiodude]] ([[User talk:Audiodude|talk]]) 01:47, 9 December 2020 (UTC)
 
::: The only address I ever used on anything Wikipedia-related is my gmail address, so at gmail.com.
 
::: Likely you going around asking previous operators is not the best way of doing it. I'd think the bot password should be declared unreachable and the right folks who deal with such issues should be notified.

== How we will see unregistered users ==
 
<section begin=content/>
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 [[m:IP Editing: Privacy Enhancement and Abuse Mitigation/Improving tools|better tools]] to help.
 
If you have not seen it before, you can [[m:IP Editing: Privacy Enhancement and Abuse Mitigation|read more on Meta]]. If you want to make sure you don’t miss technical changes on the Wikimedia wikis, you can [[m:Global message delivery/Targets/Tech ambassadors|subscribe]] to [[m:Tech/News|the weekly technical newsletter]].
 
We have [[m:IP Editing: Privacy Enhancement and Abuse Mitigation#IP Masking Implementation Approaches (FAQ)|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 [[m:Talk:IP Editing: Privacy Enhancement and Abuse Mitigation|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.
