## jScott Trapp vs jScott.trapp

Hi Oleg.

I happened to see your welcome message to User_talk:JScott_Trapp. However there is no user by that name it should have been User_talk:jScott.trapp. This was do to a mistake I made on the Wikipedia:WikiProject Mathematics/Participants. So you inadvertently created User_talk:JScott_Trapp. Perhaps you should request that the page be speedy deleted, this should work since you are the sole editior of the page. In case you don't know how, you just add the template {{delete}} to that page, you could also list the article here Wikipedia:Speedy deletion to provide an explanation. Sorry for the trouble. Paul August 18:02, Mar 22, 2005 (UTC)

Hi Paul. I put the speedy deletion template and explained on that page why it should be deleted. Thanks for pointing this out! Oleg Alexandrov 18:12, 22 Mar 2005 (UTC)

## Vacation?

Help! Somebody highjacked Paul's account while he is on vacation, and doing all kinds of things in here! Or is it a clerverly devised bot Paul wrote? :) Or does Paul mean this is what vacation means, away from work, able to concentrate on Wikipedia full time? Oleg Alexandrov 17:48, 22 Mar 2005 (UTC)

I'm just nervously doing a little editing while waiting till it's time to go to the airport, and then it's off to Sicily ;-) Paul August's Bot

Welcome back! Hope you had a good time, and are now ready to plounge back in the virtual world. :) Oleg Alexandrov 19:06, 12 Apr 2005 (UTC)

Thanks. I'm back, but I'm a bit addled, so "plounge" sounds about right ;-) Paul August 22:00, Apr 12, 2005 (UTC)

## Bot bug

Hi Oleg,

Your categories/language links bot has a minor bug. See its change to Template:0-9.

Cheers, dbenbenn | talk 03:25, 23 Mar 2005 (UTC)

Thanks. I inspect a good chuck of the changes by the bot, and I did see this particular one. However, I thought that it does not matter so much if the space is there or not. Do you think that can be an issue? Oleg Alexandrov 04:06, 23 Mar 2005 (UTC)
I can answer my own question. I think that extra space in the template introduces extra space in the article. So, sorry!
And the reason for the bug is very simple. The bot did not expect to find a page where there is absolutely nothing but a category. I will fix it. Thanks again! Oleg Alexandrov 04:27, 23 Mar 2005 (UTC)

## Matrix chain multiplication

Well, if my comment looked annoyed, but that made you finish the article, then that is good!
The article looks indeed more complete now. Forgive me for not saying more, but I don't know much about that math area. Thanks and enjoy! Oleg Alexandrov 16:00, 24 Mar 2005 (UTC)

## The two IMAs may be quite different

I don't know much about the Institute OF Mathematic and Its Applications, but the article says it's a professional society. Usually professional society means an organization that anyone in, or in many cases anyone interested in, the profession can join. I don't think the Institute FOR Mathematics and Its Applications is that kind of thing. It employs professors, mostly but not all with temporary appointments, and zillions of postdocs, and I suspect nearly no one else is affiliated with that organization. So I have doubts about the appropriateness of the category link you added. Michael Hardy 23:43, 25 Mar 2005 (UTC)

You are very right. When I added that category I did think something was odd, but did not pay much attention to it.
And I certainly should have known better. I was a grad student at the Unversity of Minnesota until last August, and being in applied math I certainly intersected with the institute on quite a bit of occasions.
PS The above also implies that we were at the same time and at the same place for at least one year, but somehow we never intersected. (Though I remember seeing you in the computer labs quite often, but that was before I started contributing here, so I had no obvious reason to get to talk to you :) Oleg Alexandrov 23:52, 25 Mar 2005 (UTC)

## Thank You

I appreciate the help and advice you have given me, and have adapted my editing accordingly. Guardian of Light 04:40, 28 Mar 2005 (UTC)

## Geometry of Complex Numbers

I am moving this to User:Pmurray_bigpond.com/Geometry of Complex Numbers while I am still investigating it.

If you are interested, ulimately I hope to build a java screen saver that does quasifuchan limit sets. (User:Pmurray bigpond.com forgot to sign)

Great you moved it. I might visit it from time to time.
About the java screen saver, I am not sure I understand what that has to do with Wikipedia. Enjoy! Oleg Alexandrov 05:09, 29 Mar 2005 (UTC)

Well, the screensaver isn't strictly to do with wikipedia, but seeing as I am going to the trouble of getting on top of all this math, it seems a shame not to write it down somewhere. Most of the stuff in Mobius Transformation is mine.

I already have a couple of other screensavers. One is an implementation of "quasitiler" (for which I had to find out about zonotopes), and the other projects world costline data onto the screen using various map projections and rolls the globe around in arbitrary directions - the idewa being that it allows you to see how the various projections distort the map. (User:Pmurray bigpond.com forgot to sign)

Got it. Just one remark. It is good to sign your posts. That is accomplished by putting four tildas one after another — ~~~~, which Wikipedia will replace by your username and date, like this: Oleg Alexandrov 05:36, 29 Mar 2005 (UTC)

## Would you assist me with a problem?

It's an integral I'm working on and it's deceptively difficult.

Guardian of Light 03:06, 30 Mar 2005 (UTC)

I can try. I cannot do it today, as I have to go home now, but you can post it on my talk page and I will look at it tomorrow. Cheers, Oleg Alexandrov 03:10, 30 Mar 2005 (UTC)

It's on my talk page in the problems section; last one.

Guardian of Light 03:13, 30 Mar 2005 (UTC)

Any leeway? Guardian of Light 04:36, 31 Mar 2005 (UTC)

do you have a page explaining how your spell checking pseudo-bot works? - Omegatron 04:08, Mar 30, 2005 (UTC)

I actually do all the changes by hand. All the bot does, is (a) identify the pages with likely misspellings from a local copy of math articles of Wikipedia, (b) fetch fresh copies of those (c) use ispell to suggest changes, (d) apply the changes I decide, and (e) upload stuff back to wikipedia. So, I do only the crucial step, deciding if a word is trully misspelled, and what the spelling should be. So, if there is any mistake, it is all my fault, not the bot.
Other questions? :) Oleg Alexandrov 04:23, 30 Mar 2005 (UTC)
Yes, I am glad that you are in the loop.  :-) Have you read through this stuff: User:Omegatron#Spell_checker? - Omegatron 04:31, Mar 30, 2005 (UTC)
I think what the page you pointed to says is that one should be careful with converting British to American English and vice-versa. No, I don't do that, I don't even bother to examine which variant shows up more often in an article. If you have other suggestions, please let me know. Thanks. Oleg Alexandrov 05:11, 30 Mar 2005 (UTC)
Yes, that's all I was pointing out. People get mad if you change one to the other. I'm not sure what ispell is. - Omegatron 05:46, Mar 30, 2005 (UTC)
I use American ispell, but I don't touch British spellings (I do remember from when I learned English, those -ise, -our, and what not). Oleg Alexandrov 05:54, 30 Mar 2005 (UTC)
Yeah that's fine then. - Omegatron 06:17, Mar 30, 2005 (UTC)
Just FYI, memoize was spelled correctly in dynamic programming (this is an eternal source of confusion, believe me). Does this bot do something to detect changes it made that were reverted like some of the others? Deco 05:43, 30 Mar 2005 (UTC)
I have all the pages on my watchlist, so I will see if some reversions happen. So far, you are the only one. And again, ultimately it is me who decides the changes, so the bot is innocent. :) Oleg Alexandrov 05:54, 30 Mar 2005 (UTC)
I changed your edits to discrete Fourier transform as well. :-) - Omegatron 06:17, Mar 30, 2005 (UTC)
Another (partial) revert at Christoffel symbols. However, that's the only mistake I found in the seven pages on my watchlist, so please continue. -- Jitse Niesen 12:44, 30 Mar 2005 (UTC)
Thank you guys. When I spellcheck with the bot, I don't have just the word in front of me, but also a large chunck of contents, so again, it is just as if I spell by hand in an editor, but faster.
About Omegatron's change at discrete Fourier transform, I think my replacement "higher dimensions" looked better than the original "multidimensions" — all in one word. But I agree that the current "more than one dimension" is even better. I will pay more attention at the context. Oleg Alexandrov 16:10, 30 Mar 2005 (UTC)
If its not the bots fault, it is the operator who needs more education in the improper change of "the same 80 kelvin interval" to "the same 80 Kelvin interval" at Equation of state. See SI, kelvin, and many other sources. Gene Nygaard 01:51, 31 Mar 2005 (UTC)
Sorry! I promise to stick to pure grammatical errors. (I thought that since it was Farenheight, and Celcius, then it must be Kelvin. Now I see I am wrong.) Oleg Alexandrov 01:54, 31 Mar 2005 (UTC)
Wow, that's quite subtle. I might have made that mistake also. Learn something new everyday. Deco 04:02, 31 Mar 2005 (UTC)
Found another — practise is actually a legitimate British spelling. I advise you add a bunch of British spellings to your dictionary to avoid trouble — changing British to U.S. will earn you silly accusations of ethnocentrism. Deco 04:20, 31 Mar 2005 (UTC)
fulfil vs fulfill is another UK/US difference. I forgot which is which, but you changed UK spelling in US spelling in equation solving. I couldn't be bothered to revert, even though UK is of course much better ;) Jitse Niesen 11:49, 31 Mar 2005 (UTC)
Noting that fulfil is on the list I gave — really, add them all, I mean it. :-) Deco 17:35, 31 Mar 2005 (UTC)
Yes, yes! I made that change before you told me about the list! I am taking off to today to learn British spellings. :( Oleg Alexandrov 17:38, 31 Mar 2005 (UTC)
Oops, sorry about that. Don't worry, it's not your fault, I'm sure you'll pick them up quickly. :-) I didn't even know about fulfil. Deco 21:26, 31 Mar 2005 (UTC)
That's fine. In case my reply was upset, sorry for that. I will resume my spelling when I manage to improve the results to error ratio. Oleg Alexandrov 23:00, 31 Mar 2005 (UTC)

And thanks for the tip on capitalization. As you can tell, I'm still getting settled in here. Nice to see that someone noticed me =)

## Edit summary

Hello, Oleg! Thanks for your welcome!

I usually do write an edit summary, maybe 85% of the time. I just leave it blank when my contribution is very simple. But I will do my best to always write an edit summary :) Porcher 09:59, 1 Apr 2005 (UTC)

## Proof Techniques

Hi there, thanks for the reminder. This was my first Wikipedia article, and I unfortunately, neglected to fix it (style issues/PNG issues). I'll take care of this soon.

Tygar 00:19, Apr 11, 2005 (UTC)

## Spelling standardization

I use a custom-written computer program that counts British and American spellings. It only considers unambiguous instances. For example, grey and gray are both correct in U.S. English, but in UK English, it's always grey. '-ize' endings are acceptable in UK English and the norm in U.S. English. '-ise' is only used in UK English and so on... SpNeo 16:09, 11 Apr 2005 (UTC)

I've created a British/American Spelling Guide. If you're interested, check it out: User:SpNeo/Spelling Guide SpNeo 16:11, 12 Apr 2005 (UTC)
See my talk page for the answer to your question. SpNeo 07:58, 16 Apr 2005 (UTC)

## Spelling

I must be a really lousy speller..it seems like every ten minutes you pick up another one of my spelling mistakes.--CSTAR 21:10, 11 Apr 2005 (UTC)

That's the whole point of my spelling project, to make certain people feel bad about themselves. :)
I was delighted to see your message. So far (see above), all I've been getting was complaints about how I misjudged something when doing spelling. (But those are getting rare lately :) Oleg Alexandrov 21:35, 11 Apr 2005 (UTC)
Actually I've also noticed you fix dozens of legitimate spelling mistakes, including some of mine. I guess it's a human tendency to make more noise over mistakes than things done right. Sorry about that. Deco 22:33, 11 Apr 2005 (UTC)
That's right Deco, it is you to whom I was thinly alluding above. :) (I should have put more smilies there, as it seems I make too many people feel bad about themselves, for one reason or another. :) Oleg Alexandrov 23:12, 11 Apr 2005 (UTC)

Your name crops up quite often on my watchlist too. But hey, at least I am not the only lousy speller on wikipedia :) MathMartin 21:49, 11 Apr 2005 (UTC)

## Overcapitalization

Hi Oleg, thanks for the style pointer. I've always been an agressive capitalizer--maybe that's why I did so well in high school German. Sympleko 10:07, 12 Apr 2005 (UTC)

## will oblige on categorizing

i see your point now on how better to categorize articles, in particular with the calculus article. regards Mayumashu 01:20, 13 Apr 2005 (UTC)

Sounds good. I should have posted on your talk page rather than reverting your work though. Hope that did not make you too mad. Cheers, Oleg Alexandrov 01:21, 13 Apr 2005 (UTC)

no, you were fine, Oleg (if i may use what is your first name, i presume). i deserved it for the calculus re-edit, which was half rashness and half not having had a morning coffee. i m at work trying to compile an all-inclusive Category:Academic disciplines page and am learning about the categorizing of academia as i go (being rather non-academic myself). my name s Matthew, by the way. took a glance at your page and saw you re in academic math - wicked! all the best with that and in enjoying wiki. Mayumashu 01:38, 13 Apr 2005 (UTC)

Nice to meet you Matthew. Thank you for your warm message. Oleg Alexandrov 01:40, 13 Apr 2005 (UTC)

I doubt the wisdom of inserting the ==Sister projects about the Julia set== heading. I did the same to the Julia page as I did to the Mandelbrot page and that I did because it did not look good having both "wikisource" and "commons" together in the "extarnal links" section. First I just moved the two links above the headline but that did not look good either so I inserted the new headline, (the best idéa I came up with). But if you do not like this? then please try to find a better solution. // Solkoll 18:40, 14 Apr 2005 (UTC)

I don't have any solutions. I am just good at criticizing. :) Oleg Alexandrov 20:02, 14 Apr 2005 (UTC)
I can take that =) // S

## Hell ...

Is Oleg Alexandrov pointing out spelling mistakes --- for all eternity.--CSTAR 02:00, 15 Apr 2005 (UTC)

He - he :) Wait till I correlate the spelling mistakes with their contributors, and make the list of top misspellers of all time. The first three will go ... Oleg Alexandrov 03:23, 15 Apr 2005 (UTC)

## Q-analog article

First, thanks for the link fix on Gaussian binomials. I'm new here and still trying to figure out these little details.

I agree that we need a q-analog article. We could start with the information I added the the q-series article, but there is certainly much more that could and should be said. (Vince Vatter forgot to sign)

Unfortunately I know nothing about q-analogs. You're all welcome to start a new article, and I can help if you have any questions.
BTW, you should have kept that default welcome I put on your page, it has good links, especially the manual of style. Oleg Alexandrov 20:18, 15 Apr 2005 (UTC)

## Changing merge templates

Please see Template talk:mergewith#Merge template changes before changing more merge templates. - Omegatron 12:42, Apr 16, 2005 (UTC)

I changed only those wich are math related (6 or so), and I fixed by hand some style issues. I do not plan to change more. Changing to the new template will be a tricky process, I am not sure a bot can do the job without user supervision and occasional tweaks. I wish the people who changed the templates thought better. Oleg Alexandrov 15:01, 16 Apr 2005 (UTC)

## Certain user-agents excluded

Thanks a lot for the offer of help--it looks like mvs is exactly what I need. FYI, mvs doesn't use "libwww-perl/..." for its User-agent: header; from line 140 of WWW::Mediawiki::Client:

140:    my $agent = 'WWW::Mediawiki::Client/' .$VERSION;


Cheers! Demi T/C 04:54, 2005 Apr 17 (UTC)

I think you are referring to the lines:
   $self->{ua} = LWP::UserAgent->new(); my$agent = 'WWW::Mediawiki::Client/' . \$VERSION;

so you are right, the User-agent is something else. I meant to say that it uses the libwww-perl library one way or another, which follows from the LWP::UserAgent->new(); thing above. Cheers, Oleg Alexandrov 05:58, 17 Apr 2005 (UTC)

Hi Oleg, I am relatively new here, but will try to contribute as much as I can.

Relax, do no more than what is fun. :) Oleg Alexandrov 04:34, 21 Apr 2005 (UTC)

I see you are from Moldova... I am actually from Russia, currently at MSU.

Right. Actually I am ethnically Romanian, with poor Russian. Oleg Alexandrov 04:34, 21 Apr 2005 (UTC)

My twin's name is Oleg. So strange... Igny 03:34, 21 Apr 2005 (UTC)

Coincidences do happen. :) Oleg Alexandrov 04:34, 21 Apr 2005 (UTC)

## Regarding my RfA

Hello Oleg. I was promoted to admin today, and I wanted to thank you for the time yo took to consider my RfA. As a result of your comments, and those of others about my low edit count (and possible inexperience in certain areas of WP), I will proceed with caution when using my privileges. I hope not to disappoint you. Thanks. Phils 20:11, 21 Apr 2005 (UTC)

Congratulations! You have the traits of a good admin. Oleg Alexandrov 20:40, 21 Apr 2005 (UTC)
