Articles you might like to edit, from SuggestBot
SuggestBot predicts that you will enjoy editing some of these articles. Have fun!
SuggestBot picks articles in a number of ways based on other articles you've edited, including straight text similarity, following wikilinks, and matching your editing patterns against those of other Wikipedians. It tries to recommend only articles that other Wikipedians have marked as needing work. Your contributions make Wikipedia better -- thanks for helping.
If you have feedback on how to make SuggestBot better, please tell me on SuggestBot's talk page. Thanks from ForteTuba, SuggestBot's caretaker.
P.S. You received these suggestions because your name was listed on the SuggestBot request page. If this was in error, sorry about the confusion. -- SuggestBot 12:44, 8 September 2006 (UTC)[reply]
Sidebar redesign final vote!
It's that special, special time! No, grandma's not coming over. No, not time to clean out the fridge. It's sidebar redesign voting time! Yes, the community has narrowed it down to 3 different options, and a vote for the same old original sidebar is a choice one could vote for as well. Voting for multiple options is allowed, and discussion on the whole shebang is right there on the vote page itself.
Since the editor seemingly very recently acquired a brand new user, perhaps you could try to put a messag to User_talk:Laljag, stating I reverted your edit since it was nonsense, but welcome anyhow in an as friendly manner at possible :-) ? JoergenB 12:41, 6 October 2006 (UTC)[reply]
Right; I should do this more often, but it gets quite tiresome after the hundredth revert. Granted, template messages like Template:Welcome have been created to make the work easier, but finding a template that fits the occasion is almost as much work as writing one.

The images will look the same.
And infoboxes are far more flexible.
Are you familiar with infoboxes?
--Jtir 12:07, 7 October 2006 (UTC)[reply]
You're just introducing unnecessary complexity and inconsistency. Please explain what you are going to use this extra flexibility for. Fredrik Johansson 12:15, 7 October 2006 (UTC)[reply]
Text alignment can be controlled. I have centered some captions and left aligned others. The alignment may need some tweaking. Further, they eliminate clutter -- namely the small resize icon that indicates the image is a thumbnail. In some cases the result has been a smaller box, which saves screen space. Also they support titles above the boxes if editors feel those would be desirable. Have you looked at any of the edits I have made? --Jtir 12:24, 7 October 2006 (UTC)[reply]
If you don't like the size, icon and alignment, you can edit your own stylesheet to that end. I want image boxes in this article to look the way they do in other articles when I view them, thank you. Fredrik Johansson 12:40, 7 October 2006 (UTC)[reply]
Most readers of the encyclopedia probably don't have your ability to edit stylesheets. What differences have you noticed after the changes I have made? --Jtir 12:56, 7 October 2006 (UTC)[reply]
Another advantage to infoboxes is that images and captions can be stacked more densely, as this sandbox example shows. --Jtir 13:21, 7 October 2006 (UTC)[reply]
(founder, actually), I figured I'd drop you a line and see if there was anything you thought should be added/removed/cited on the article before it is sent to FAC. We definitely want it to pass! :)

Another little thing, it will be nice to release another screenshot (of Image:Doom mapformat screen.png) without comment, because it's more easy to translate english image without alterating the picture. 193.248.38.17 17:18, 30 November 2006 (UTC)[reply]
UK Roundabout
An image you are listed as having worked on is up for delisting as a featured picture: Wikipedia:Featured picture candidates/UK Roundabout delist. The image creator is gore from Wikipedia, but you apparently made the most recent version. One of the main criticisms is that the frame rate of the animation is poor and that a higher frame rate at the expense of file size would be beneficial. Would you care to comment, or can you make an improved version? --Dgies 04:41, 4 December 2006 (UTC)[reply]

Thanks for uploading Image:Ron Rivest.jpg. I noticed that the file's description page currently doesn't specify who created the content, so the copyright status is unclear. If you did not create this file yourself, then you will need to specify the owner of the copyright. If you obtained it from a website, then a link to the website from which it was taken, together with a restatement of that website's terms of use of its content, is usually sufficient information. However, if the copyright holder is different from the website's publisher, then their copyright should also be acknowledged.
As well as adding the source, please add a proper copyright licensing tag if the file doesn't have one already. If you created/took the picture, audio, or video then the {{

Image question
Dear Fredrik; you say you currently edit very little, but allow my to post at your talk page. If the deletion backlogs on Commons continue to drag on as they currently are, you should have at least 2 months to deal with the issue.
An image you uploaded and tagged as taken by your dad, never got tagged with a license. I added a license to it -- GFDL-presumed -- but now I demand to get it properly certified or deleted, and have nominated the image for deletion.

Holland Land Company
Hello Fredrik, can you do me a favour and upload the map of the Holland Purchase to Commons, or send me a copy, with all the information you have on the date or the publisher? I wrote an article in the Dutch Wikipedia about Gerrit Boon. I like to use the map, probably also for a lemma on the Holland Land Company.Taksen (talk) 19:45, 18 November 2008 (UTC)[reply]
BBP-like formulas I came up with
Hi,
Few days ago I came up with this three symbol Pi BBP derivative formula
Jon Borwein doesn't think that this result is "interesting" - see below
(though his approach in getting my formula doesn't sound like exact
science to me, since it requires for everyone to do what I did, that is to perform the "trial and error" search for the formula).
BTW, Jesus Guillera is not so *negative* in his formula assessment (see my Google chat with him further below).
From: Jon Borwein
Any rational has a BBP formula.
If a, b have BBP formulas so does a+b.
At the crudest level: find a formula for each number in base b and add
them. Then use simplification tools to remove redundant terms.
12:46 PM me to Jesús Guillera : Nov 30 (2 days ago) Maple
Pi= 2/3 * (-1 + Sum(7/(4*k+1) - 6/(4*k+3) - 1/(4*k+5),k = 0 .. infinity)
Hi Jesus - is above easy to obtain ?
Jesús Guillera to me
1:04 PM Jesús: Hi Alex, there is an easy proof of that formula if you convert it in an integral. For it, observe that...
1:07 PM int_(0,1) x ^ (4n+a) = 1 / (4n+a+1)
1:09 PM me: Thanks !
1:10 PM Is it worth posting or it is so trivial ?
1:16 PM Jesús: The proof is easy but it can be interesting if one does not know the method. The formula converges slowly because there is not a factor like for example 1/16^k.
Also for whatever it is worth,
here is the alternative formula for ln(3) which I derived and which is not listed in
http://www.mathworld.wolfram.com/BBP-TypeFormula.html
ln(3) = 1/4*(1+ Sum((1/(9)^(k+1))*(27/(2*k+1) + 4/(2*k+2) + 1/(2*k+3)), k = 0 .. infinity) )

4^x - x^4
Hi Fredrik. Love the images! How did you create them? (I ask because I work in R and we have a similar functionality, but I never seem to manage to create such zingy graphics).
Cheers, Robinh (talk) 20:19, 6 December 2008 (UTC)[reply]
This was done with matplotlib, using the wrapper function cplot in mpmath.
Nothing particularly fancy about it; just sampling the function across a grid, mapping function values onto RGB, and displaying the image. I guess much of the zinginess (is that a word?) comes from the choice of color function. Fredrik Johansson 20:39, 6 December 2008 (UTC)[reply]
Fair use rationale for File:DEU.png
Thanks for uploading or contributing to
fair use but there is not a suitable explanation or rationale as to why each specific use in Wikipedia constitutes fair use. Please go to the file description page and edit it to include a fair use rationale
.
If you have uploaded other fair use media, consider checking that you have specified the fair use rationale on those pages too. You can find a list of 'file' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "File" from the dropdown box. Note that any non-free media lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you. Ysangkok (talk) 01:31, 11 January 2009 (UTC)[reply]
