Why delete my effort for more browser compatibilty, the look is the same i have parse errors on firefox and opera browser on linux ubuntu. These are resolved now. I do not understand what you're motives are of deleting my wiki effort? — Preceding unsigned comment added by 184.108.40.206 (talk) 12:28, 7 February 2014 (UTC)
Dear Jitse Niesen,
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 communityHERE, 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 email@example.com (to maintain anonymity) and I will add your name to my offline contact list. If you feel comfortable doing so, you can post your nameHERE instead.
If you have questions or concerns at any time, feel free to email me at firstname.lastname@example.org. I will be more than happy to speak with you.
Thanks in advance for your help. We have a lot to learn from you.
Why did your bot delete my merge request?
- I'm sorry that your work got deleted. As it says at the top of Wikipedia:Pages needing attention/Mathematics, the lists are maintained by the bot and the part between the <!--jngoim:merge--> markers is periodically overwritten. You are welcome to add your text outside the markers if you want; the bot should preserve that. Additionally, there was a problem with the bot which meant that it did not list any pages at all; that is now fixed. -- Jitse Niesen (talk) 22:30, 23 February 2012 (UTC)
- Silly bot! I'll give it a shot.KlappCK (talk) 04:16, 24 February 2012 (UTC)
Invitation to events in June and July: bot, script, template, and Gadget makers wanted
I invite you to the yearly Berlin hackathon, 1-3 June. Registration is now open. If you need financial assistance or help with visa or hotel, then please register by May 1st and mention it in the registration form.
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 other upcoming events where you can learn more about MediaWiki customization and development, how to best use the 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.
Check out the the developers' days preceding Wikimania in July in Washington, DC and our other events.
Best wishes! - Sumana Harihareswara, Wikimedia Foundation's Volunteer Development Coordinator. Please reply on my talk page, here or at mediawiki.org. Sumana Harihareswara, Wikimedia Foundation Volunteer Development Coordinator 00:13, 4 April 2012 (UTC)
predictor corrector method
Thanks for the update to Predictor–corrector_method. At the time I added the euler trapezoidal example, there wasn't much in the article before and I had no references to cite, just writing it based on memory from decades ago. You might want to restore or add some comment about the corrector method being based on trapezoidal method, which is linear and not as accurate as a higher order method. For example, Runge Kutta 4 will usually be more accurate than 1 euler and multiple (3 or more) trapezoidal corrector steps. Rcgldr (talk) 19:30, 11 June 2012 (UTC)

I agree with the move from 2nd Order Interpolation to Second-Order Interpolation. But I noticed you also added that it could be called biquadratic interpolation, as a 2nd degree version of bicubic interpolation? Second-Order interpolation is a different method altogether. Notice that in bicubic interpolation you use information about the http://www.nytimes.com/2010/12/07/science/07first.html?ref=sciencehttp://www.nytimes.com/2010/12/07/science/07first.html?ref=sciencewhich is not the case in second-order interpolation. So in summary I don't believe this method had been discovered before, so let's discuss what should be done with the page.Bpthurston (talk) 22:42, 2 August 2012 (UTC) — Preceding unsigned comment added by Bpthurston (talk • contribs) 22:40, 2 August 2012 (UTC)
It is highly possible you forgot about an edit you made to Talk:Korfball in 2006. I was doing some research on something else, and ran across a relevant cite, which I just added to the Talk page so I'll leave it to you to see if there's anything to be done.--SPhilbrick(Talk) 18:58, 27 October 2012 (UTC

Tridiagonal matrix similar to Hermitian matrix
Dear Jitse Niesen,
I found that in the article Tridiagonal matrix you added condition for the matrix to be similar to Hermitian matrix: ak,k+1 ak+1,k ≥ 0. I found references only for strict inequality. Could you please give the reference(s) on non-strict condition?--Krystofer (talk) 14:44, 14 March 2013 (UTC)
- Dear Krystofer, I'm afraid my text was not very clear: with the non-strict condition, the matrix is not necessarily similar to Hermitian, but it still has real eigenvalues (think of the matrix [1 1;0 1]). I added a reference and tried to clarify the text. -- Jitse Niesen (talk) 15:43, 14 March 2013 (UTC)
Expanding/Adapting Jitse bot
Hello Jitse! I've been looking around for a bot to update clean-up listings and I finally found yours. Many WikiProjects previously used User:WolterBot but the supporting user has left, the bot died and the code has left with him. A slow ToolServer fix has been around, but it doesn't compare to the excellent output of your bot.
I checked out the code, but it didn't appear to be commented. I also noticed the bot has several functions, so I thought it might be easier to ask you how to extend the code to include updated clean-up listings for other projects. I'm familiar with python and could certainly work on the code, and/or learn to create a new bot. Thanks! Scientific29 (talk) 12:42, 19 April 2013 (UTC)
- Hello. I'm quite willing to help you with understanding the code. It is indeed not commented and it has grown over time in a mess that I'm not particularly proud but it (mostly) does its job. One difference with WolterBot (if I remember correctly) is that WolterBot uses a category to find which pages belong to a particular WikiProject, but my bot uses the output of another bot, User:Mathbot, which writes a list with all maths pages.
- At the moment, I'm running the bot on a computer at a university where I used to work, but I'm quite keen to move it to the ToolServer (or whatever it supposed to take its place). As you may have noticed, my Wikipedia activity has dropped considerably, so this may give me the impetus to do some work.
- How shall we continue? Can you tell me in a bit more detail what you want to do? -- Jitse Niesen (talk) 15:53, 25 April 2013 (UTC)
http://www.ma.hw.ac.uk/~jitse/wikipedia/rpim.php seems to have stopped working — indeed http://www.ma.hw.ac.uk/~jitse now gets a 404. Is there any replacement, for instance via your leeds address? —David Eppstein (talk) 06:52, 20 August 2013 (UTC)
- No. I intend to transition it to the toolserver, but probably won't have time for it this week. I removed the link from the Wikipedia:WikiProject Mathematics for now and will put it back when I get it working again. Thanks for letting me know; I hadn't noticed. -- Jitse Niesen (talk) 08:13, 20 August 2013 (UTC)
- It's back. ---- Jitse Niesen (talk) 18:04, 30 August 2013 (UTC)
Thank you for removing the technical and improve banners. I was tempted to remove them myself but I did not want to get into an edit war with the editor who put them there. I believe that many mathematics articles are necessary technical and that the Matrix splitting article was quite clear and no more difficult for the average reader than many other articles about advanced mathematical topics, but that editor maintained that an article should not be technically difficult to understand just because "other stuff exists." I suppose that some situations like this are a "judgment call."
Dear Jitse, I understood your point. The problem is Victor was neither a rock star nor a man of high administrative position at the Saint Petersburg University. Just a man who always told what he thought and thus sometimes not very comfortable to deal with. As you may see from the list of his achievements, he actually retired from the University many years ago and, I am afraid, is quite forgotten by the administration. I asked some people "in position" to post something official, but I am not sure I will succeed, especially due to the fact that since 1999 I leave in Lisbon. I may ask Marina, Victor's daughter, to scan his death certificate, but I am not very comfortable to publish it in the net. Are there some alternatives? Yours, Andrei Utkin, Victor's co-author Outkine (talk) 14:35, 8 December 2013 (UTC)
