message: Will we try to update our PlanetMath article lists as new articles are created on PlanetMath? Paul August  ☎ 15:31, Feb 1, 2005 (UTC)
:These days I will try to learn how to fetch wiki-markup code from Wikipedia, and how to upload it back. I have some hints that this should be possible. If so, it will be very easy to automate completely the process of maintaining the lists. Then, from time to time I would just need to run my script to update these pages with new PlanetMath articles. 
: And in connection with Ben's comments. If it becomes easier to maintain these pages, it will be possible to suggest more intelligent guesses for corresponding Wikipedia articles and then again rerun the script to update the pages (this will not overwrite any comments or anything already in there).

thread_title:  New articles on PlanetMath? 

message: There is a list of unclassified PlanetMath articles at http://planetmath.org/?op=unclassified that might need to be processed as well.  Fortunately there is only one article there right now.  CryptoDerk 23:59, Feb 1, 2005 (UTC)
: Well, it is not unclassified because it cannot be. Hopefully articles stay there only temporary, until somebody puts them where they belong. I will keep on eye there too from time to time. Oleg Alexandrov  | talk 02:03, 2 Feb 2005 (UTC)
thread_title: Unclassified PlanetMath articles

message: The alt text for images won't always work.  Specifically in cases of long LaTeX lines.  As an example, see Conway's chained arrow notation.  I'll update the relevant instructions to tell people to watch out for this, but I wanted to let everyone know here as well. CryptoDerk 06:35, Feb 2, 2005 (UTC)
:I guess there is a limit to how long the alt could be. It is good you noticed that. Oleg Alexandrov  | talk 16:00, 2 Feb 2005 (UTC)
thread_title: Copying the page doesn't always work!

message: Of course, much of PM's content is appropriate for WP also, but I just discovered a set of articles on neutrosophic probability, statistics, sets and logic that appear to be quite unsuitable.  It seems that articles on neutrosophic sets, logic and 'neutrosophy' in general have been deleted from WP (they are still in Google's index, however).  My guess is that on WP it was deemed a neologism, original research or somesuch.  I think I've noted them all as Not needed on WP.  Again its something to keep an eye out for, but I'm sure we'll catch most of these cases.  Ben Cairns 06:24, 3 Feb 2005 (UTC)

thread_title:  Unsuitable articles on PlanetMath 

message: I've just added a 'status update' to 60-XX Probability theory and stochastic processes, despite there being 46 unreviewed articles (29 have been reviewed).  I think that provided it's not overused in small or barely-examined categories, the benefits of this outweigh the disadvantages (such as the added clutter), but wanted to ask the rest of you what you thought.

thread_title:  Status updates 

message: Eventually all the ugly characters which did not get encoded properly in the autogenerated list will need to be replaced when an automatic update is performed (again, for now wix is broken). 
In spite of looking very carefully through several pages I did not find any more than the two I listed at Wikipedia:WikiProject Mathematics/PlanetMath Exchange/encoding issues. If you run into more, just put them there. Oleg Alexandrov 04:31, 17 Feb 2005 (UTC)

thread_title: Encoding issues

message: I finished and tested the code for automatically updating things from PlanetMath. I must say it took forever for me to finish that, both because of technical issues (like Wikipedia changing some of their protocols, etc), and due to my laziness. 
But either way, I mirrored this project at User:Oleg Alexandrov/PlanetMath Exchange/, and then wrote over it the updates from PlanetMath. So, if you visit that page, go to each individual lists, and do a diff of the current version (with updates from PlanetMath) and the one before it (which is just a copy of what we have here), you will see what the changes are.
Two remarks are in order. First, on PlanetMath they sort the articles alphabetically, with the exception of the names of mathematicians, which are sorted by last name, and with the exception of article titles starting with formulas, which are sorted separately. I was not able to reproduce that, I sort everything alphabetically, so in a few places things are a bit displaced. 
Second, now all the sections are sorted by section number. Before that, the order was a bit strange, and I suspect I might have inherited that from the PlanetMath structure. So in some (just a few) places, some sections are interchanged. 
I looked at around 10 diffs and it seems my script does not screw anything up (except it removed some of Paul's comments which were not attached to a specific article, but rather, to certain sections; but that happened only in one section, and is I think, not crucial).
When you get to it, I would like to ask you to check some diffs too, to see if there are any problems. Then, at some point, we will need to stop the work on our project for around 15 minutes to do the updates. This does not have to happen anytime soon, as we do have still plenty of work. 
Our exchange project is going well, and I (and hope you too) am happy. Oleg Alexandrov 01:14, 14 Mar 2005 (UTC)
replies: text: Brilliant, Oleg!  I checked 60-XX and 39-XX and they seemed to work fine.  The only suggestion I would make is that if _NOTOC_ has been removed from the page, then it would save removing it again if it wasn't added in the update -- of course this is a very minor thing.  Overall it seems to work very well; thank you!  Ben Cairns 00:59, 15 Mar 2005 (UTC)
replies: text: Ok, great, but how do I use this? I see for example, that  33-XX special functions on PM has changed. Should I copy those changes to here? If so, then how will I detect future changes?  Note that I have been hacking 33-XX over here since you last updated over there. linas 18:41, 26 Mar 2005 (UTC)
replies: text:  I would need to copy over the new stuff from PlanetMath to my computer, then copy our project too, merge them, and upload back here. All of that is automated. One day when we feel we did a lot of work and want new stuff, I will do that. Oleg Alexandrov 18:57, 26 Mar 2005 (UTC)
thread_title: Status of automated updates (it seems it works)

message: I was wondering if it might be appropriate to add category listings to the Template:PlanetMath attribution and Template:PlanetMath reference templates, so as to identify those articles that use PM material under license or that cite a PM article.  I'm not exactly sure on the suitability of such categories (although there are stub categories so why not these?) -- could someone else comment on the suitability of this?  On particular concern is that it might clog up the category listing at the bottom of a page if it licenses PM text and cites an article.  Perhaps there is a way to get around this?  Cheers, Ben Cairns 01:07, 15 Mar 2005 (UTC)

message: Is any one else experiencing problems viewing the images in PlanetMath articles? For example when I try to download this page: axiom of power set: My browser (Safari) reports errors of "can't connect to host", for each png on the page.

thread_title:  Problem with PlanetMath site? 

message: There's a thread right now at Planetmath discussing the content exchange between the sites, and it has been raised the point that wikipedia may not be holding GFDL as well as PM does. So I would like some feedback. The thread is at PM's embedding entry. Basically, jac comments:
Copying or copy-and-modifying from Wikipedia is NOT fine in my view, since until the site admins (for both sites, actually) take action, such copying is not going to be GFDL compliant.
I asked for comments got the reply
Simply put: I don't think Wikipedia is conforming to the GFDL's requirements for acknowledging GFDL'ed source materials, and I also think that they have set up their site in such a way that it is infeasible to conform to the GFDL when using their materials. 
and a further analysis of most itens on the GFDL and his comments on each.
At the botom he also states that
In my view, none of the articles can be copied (using them as references is of course OK, the same way you would use non-FDL'ed works) until further work has been done by the admins of both sites. When the appropriate steps WRT licensing have been taken, then all of the wikipedia articles should be usable.
so, I wanted more eyeballs on the issue to see what can be done from each side if indeed there's an issue (for instance I think WP articles taken from PM do not cite at least (or fewer if less) 5 authors from the original PM entries. Comments, anyone?

thread_title:  Planet math links 

message: If not, I could have the bot put the status of all proof articles as N, meaning not needed. This would overwrite the status field when the status field is empty, and leave it the way it is otherwise. Oleg Alexandrov (talk) 08:40, 22 October 2005 (UTC)
replies: text: I don't like that; I wish to keep a human element here. For instance, proof of Schur decomposition is a proof article, but I still decided that the proof should be included in Wikipedia because it is a constructive proof, and the construction is actually important in numerical algebra when one wants to compute a Schur decomposition. -- Jitse Niesen (talk) 13:25, 22 October 2005 (UTC)

text: I agree with Jitse. Paul August ☎ 17:56, 22 October 2005 (UTC)
replies: text:  Yes, good points. But putting the tag N on a proof could be a good initial guess, and may give us a better idea of how many articles are left to copy. Oleg Alexandrov (talk) 19:08, 20 November 2005 (UTC)
thread_title:  So, are proofs needed or not? 

message: We were wondering who is clicking so often on the mathbot link having it update the statistics. Well, I started keeping a log, at Wikipedia:WikiProject Mathematics/PlanetMath Exchange/Log. Except for a couple of clicks from Berkely last night, most are clicks from the google page crawler and an Inktomi search bot. Interesting. Oleg Alexandrov (talk) 23:02, 26 October 2005 (UTC)
replies: text: This is as amusing as it must be frustrating.  When I first checked the logs for my professional web page a few years back, I quickly noticed that the VAST majority of hits were from bots, particularly my own university's search bot!  Eventually, I had to add a dummy link, invisible to graphical browsers, so that I could establish a rough baseline.  No doubt you are able to put in place a more elegant solution than mine!  Ben Cairns 10:55, 27 October 2005 (UTC)

text: A more elegant solution ... who cares? :) A bot calculates the statistics, other bots prod it to do work, and all left for humans is do their little part, reviewing PlanetMath articles. :) Oleg Alexandrov (talk) 12:39, 27 October 2005 (UTC)

text: Well, what could be more elegant than doing nothing? :)  I was under the (false) impression that the 'culprits' had done a bad thing.  These bots are pretty useful little triggers for things that need occasional updating.  I wonder what else they could be used for... Ben Cairns 14:35, 27 October 2005 (UTC)

replies: text: Redirects?  It is pretty silly, for example, that "Mathieu groups" doesn't redirect to "Mathieu group." This is a somewhat delicate process, but it could probably be automated to some degree.  Jtwdog 18:56, 27 October 2005 (UTC)
replies: text:  That would be very complicated. We are talking about tens of thousands of redirects and without any background information about the articticles to redirect to, one can also get it wrong. About the "Mathieu groups" though, the Wikipedia convention is that in absolute majority of cases one should not link to plural anyway. Oleg Alexandrov (talk) 02:23, 28 October 2005 (UTC)
thread_title:  I found the culprit 

message: There's an image on http://planetmath.org/?method=l2h&from=objects&id=968&op=getobj which I don't know how to copy, since I don't think it falls under fair use. Since it IS PS of some sort (*.eps) isn't it possible to copy that source, then have the typesetter reconstruct it over here, or am I just going to have to omit it? - CorbinSimpson 06:32, 21 January 2006 (UTC)
replies: text: The whole of PlanetMath, including the pictures (as far as I can see), falls under the GFDL, like Wikipedia. So I think you can just copy the PNG image to either the English Wikipedia or the Commons and tag it as GFDL, including the URL where you got it from. I assume you only have problems with the legal issues; if your problems concern the technical process, please let me know and I'll copy it for you. -- Jitse Niesen (talk) 13:20, 21 January 2006 (UTC)
