## Touchgraph

Image:WorldWideWebAroundGoogle.png and Image:WorldWideWebAroundWikipedia.png were created with touchgraph, which itself use the relate function with google. I modified the image to remove some ugly (special char) links, and then took a screenshot. About the copyright: I assumed I have the copyright, since i ceated the images using the touchgraph software, as someone would create an image using gimp. I then released the images under the GFDL license. However, I am no legal expert, and there is a possibility that my assumptions are wrong. -- Chris 73 Talk 20:33, Aug 31, 2004 (UTC)

## I thank you for commenting: minor edits???

im not complaining as such, as the edits tend to be ok, nessisary and of good qulity. HOWEVER deleting/adding/re-wording large chunks of text are NOT minor edits. just a thought. tooto 09:39, 18 Sep 2004 (UTC) oh, personaly i think having your proffile sat to say "Mark all edits minor by default" is an extreemly bad idea, espesialy if you arnt one for doing small spell checking/copy editing

I must ask you to specify which setting "Mark all edits minor by default", Im sure Ive come accross it somewhere, but not bothered with it. I do sometimes make small edits, spellings etc, but prefer to create new pages.

All the best: Faedra 13:53, 18 Sep 2004 (UTC)

Ahh! found it, cheers, but the box you mention is not checked~? Faedra


## The Humungous Image Tagging Project

Hi. You've helped with the Wikipedia:WikiProject Wiki Syntax, so I thought it worth alerting you to the latest and greatest of Wikipedia fixing project, User:Yann/Untagged Images, which is seeking to put copyright tags on all of the untagged images. There are probably, oh, thirty thousand or so to do (he said, reaching into the air for a large figure). But hey: they're images ... you'll get to see lots of random pretty pictures. That must be better than looking for at at and the the, non? You know you'll love it. best wishes --Tagishsimon (talk)

## Image tags

I was wondering about your adding tags to Image:Me-Ow1918.jpeg, previously tagged PD-US, correctly as pre 1923. You added "albumcover", which it certainly is not. Why? Also, I notice you added "PD-70". Do you have a death date for Mel B. Kaufman? If so, could you please tell me, as I don't know it. (Please note that the tag you added is dependant on knowing that information.) Thanks, -- Infrogmation 00:13, 18 Dec 2004 (UTC)

## Image tagging---be careful!

Hi! Thank you for helping out with the Humungous Image Tagging Project. It's a large undertaking, and can use all the help it gets. That said, tagging images as GFDL even when you don't know their license status is bad practice. (I'm referring to Image:Kiribati flag large.png and Image:Kazakhstan flag large.png off the top of my head here, but I haven't gone over any of your other edits.) If you can't determine an image's copyright status, it's better to either tag it {{unverified}} (and preferably leave a comment on the uploader's talk page asking them where it came from) or just leave it alone. This job isn't enough of a rush not to be worth doing properly.

Remember, if a contributor licenses their text contributions under more licenses than just the GFDL (like, for a random example, User:AndrewKepert), you need to include their other licenses in the image's tag-list. For instance, that user licenses under Creative Commons Attribution ShareAlike 1.0 and 2.0. So any image created by that user would be tagged with all of the following copyright tags:

{{GFDL}}
{{cc-by-sa}}
{{cc-by-sa-2.0}}

While, for instance, governmental flags are all {{PD-Flag}}, or {{PD-USGov-CIA-WF}} if you can be absolutely sure they came from the CIA World Factbook. Public domain images are more flexible in their available uses than GFDL images, so this distinction is important.

Don't let this stop you from helping out, but remember that we can never assume that someone else will fix something we leave in a maybe-broken state. This is especially true for copyright tags, which will most likely be used by people who want to (for instance) include Wikipedia with their latest Linux distribution.

Thanks for your contributions; if you have any questions, please don't hesitate to comment on my user page! grendel|khan 08:04, 2004 Dec 27 (UTC)

## BBC 4

I guess you also listen to Radio 4. My first thought was also "I wonder if a wikipedia article has been written on auxetics" :) --Eean 08:33, 21 Mar 2005 (UTC)

## Style tip

Just a note, in math notation variables should be italic, like x or ${\displaystyle x}$, rather than x. And also, an edit summary is good to have. :) Cheers, Oleg Alexandrov (talk) 00:48, 26 April 2006 (UTC)

${\displaystyle r_{1}=atan\left({\frac {\sin 60^{\circ }{}}{{\frac {\sin r_{2}}{\sin i_{1}}}+\cos {60^{\circ }{}}}}\right)}$

## Relationship between Institutional Review Board and Tuskegee Syphilis Study Entries

Thank you for correcting the internal Wikipedia link, which prompted me to improve (I hope) the phrasing of the IRB entry itself. It is an important area to represent with accuracy. TrueC 14:20, 22 June 2006 (UTC)

## Image:Lactose.png listed for deletion

An image or media file that you uploaded or altered, Image:Lactose.png, has been listed at Wikipedia:Images and media for deletion. Please look there to see why this is (you may have to search for the title of the image to find its entry), if you are interested in its not being deleted. Thank you. —Nv8200p talk 16:33, 26 November 2006 (UTC)

## Lanc

Please see Image talk:Lanc.600pix.jpg -- Philip Baird Shearer 12:45, 8 February 2007 (UTC)

Well, It's an old picture upload(by Wikipedia standers), before we had well defined image use guidelines. When people ask if they can use a picture on Wikipedia, they usually said something along the lines of "is it ok to use this picture on Wikipedia", not "is it ok to use this picture on wikipedia, and is it also ok for anyone else to use it if they areusing part of the article where it is found..." (which most people would consider is writing a blank check, so wouldn't allow.
Therefore, unless it has explicitly been put under a computable licence, its considered non-free.
(note that this dosn't stop someone else from asking again for permission to use the image under a licence that is compatible with Wikipedias image use guideline's) --tooto 01:16, 10 February 2007 (UTC)
Thanks for the explanation. Just a thought, as others may ask this question, perhapse a standard comment on the the picture's talk page could save everyone time. --Philip Baird Shearer 09:50, 10 February 2007 (UTC)

## Co-ordinate system transformation

Back to the question... I have chosen to do a worked example of finding the centre of the rectangle, as I wanted to do some maths by hand to convince myself of what is happening!

The setup I have used:

• start X = 0
• start Y = 0
• start width = 200
• start height = 100
• transform = matrix(1,0.5,-0.5,1,25,-20)

The transform matrix can be re-written as:

${\displaystyle {\begin{pmatrix}1&-0.5&25\\0.5&1&-20\\0&0&1\end{pmatrix}}}$

the corner of the retangle was:

${\displaystyle {\begin{pmatrix}0\\0\\1\end{pmatrix}}_{corner}}$

the centre of the rectangle was:

${\displaystyle {\begin{pmatrix}{\tfrac {200}{2}}\\{\tfrac {100}{2}}\\1\end{pmatrix}}_{centre}={\begin{pmatrix}100\\50\\1\end{pmatrix}}_{center}}$

so now multiplying the coordinates of the center of the rectange with the transfromation matrix gives:

${\displaystyle {\begin{pmatrix}x\\y\\1\end{pmatrix}}_{new}={\begin{pmatrix}1&-0.5&25\\0.5&1&-20\\0&0&1\end{pmatrix}}\cdot {\begin{pmatrix}100\\50\\1\end{pmatrix}}_{center}}$

${\displaystyle {\begin{pmatrix}x\\y\\1\end{pmatrix}}_{new}={\begin{pmatrix}100-25+25\\50+50-20\\0+0+1\end{pmatrix}}_{new}={\begin{pmatrix}100\\80\\1\end{pmatrix}}_{new}}$

so the new centre of the rectangle is: x=100, y=80.

These are the coordinates of the rotation centre in Inkscape after applying the transformation matrix.

## ArbCom elections are now open!

Hi,
You appear to be eligible to vote in the current Arbitration Committee election. The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to enact binding solutions for disputes between editors, primarily related to serious behavioural issues that the community has been unable to resolve. This includes the ability to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail. If you wish to participate, you are welcome to review the candidates' statements and submit your choices on the voting page.
