From Wikipedia, the free encyclopedia

Hi, and welcome to the Wikipedia! If you haven't seen it already, there's some useful information at the welcome page, as well as plenty of stuff to answer any questions you might have in the Help section. And if you get stuck or have some questions feel free to add a question to the Village Pump.

Addendum to the standard greeting: I see you've alread done a great job on Metapost, so most of the above new-user-welcome information is probably unnecessary. --Delirium 09:38, Aug 4, 2003 (UTC)

You should add yourself to Wikipedia:Wikipedians/Australia. By the way, our naming convention for cities and towns is as follows: US and Canada uses [[Place, State]], everywhere else uses [[Place]] if the name is unique, or [[Place, Country]] if it is used elsewhere. See Talk:Gosford. -- Tim Starling 03:49, Aug 7, 2003 (UTC)


Thanks for your help. --David Blandford 04:02, 16 Jun 2005 (UTC)

Hey :) I've removed the silly comment at Golden mean base. It's not really encyclopedic making jokes inline in articles, is it? :)

Good job in editing the page though. Keep it up! :) Dysprosia 01:40, 19 Sep 2003 (UTC)

Pontryagin duality reads fine, but I wondered why you created this instead of adding to and/or rewriting dual group.

Im not the author of that one. Michael Hardy 01:57, 17 Nov 2003 (UTC)

[edit] License ?

Hi, you had uploaded the pic Image:Metapost ex.png without giving the license. We use it on french wp and I'd like to know wether it is GFDL or Public Domain ... Thanks in advance. Tipiac 12:26, 13 Jul 2004 (UTC)

[edit] Polyhedrons

Made a program for drawing flat polyhedrons, doesn't work out 3d coordinates, though. No promises, but it might be possible to get it to guess the 3d coordinates. I don't know if you know C, but since you can use POV-ray, there's a chance of you knowing C, too. See image:makepolys.c

Output of the program (so far):
tetrahedron. (redrawn in SVG)
hexahedron. (redrawn in SVG)
octahedron. (redrawn in SVG)
dodecahedron. (redrawn in SVG)
icosahedron. (redrawn in SVG)
pentagonal pyramid. (redrawn in SVG)
square orthobicupola. (redrawn in SVG)

(Feel free to remove the above, if it looks cluttered.)
Maybe the program could be useful or interesting...

If possible, it might look better if the white border of the 3d Johnson solids was cropped, so they could be bigger in less space.

P.S. Unfortunately, it isn't possible to upload non-image files any more. (The .c program is saved in an image description page for an image which doesn't exist.) Κσυπ Cyp   2004年11月5日 (金) 00:30 (UTC)

Fair enough. I have done similar things in Metapost previously. The built in drawing, colouring, paths, transformations make this sort of thing easy - far easier than C. By the way, I have povrayed the Snub disphenoid the first one not based on any archimedian. A simple optimisation algorithm within povray did the trick, but I have yet to try it on a non-deltahedron. Keeping triangles planar is easier than keeping other polygons planar! Andrew Kepert 01:19, 5 Nov 2004 (UTC)
PS and I know about the framing problem. The problem is that your Poly.pov code frames the bounding sphere, which doesn't work so well for odd-shaped polyhedra. An autobalance() [AGK's macro] on the vertices before finding faces helps. I was going to modify Poly.pov to find an optimal frame just before the final camera declaration.

[edit] Sydney Maps

Hi AndrewK,

I'm a little late in replying. :) But I'm back on Wikipedia now. I can send you the base maps if you want. I hand-vectored them in Photoshop from a preexisting map because I have no GIS software. Randwicked 10:14, 22 Nov 2004 (UTC)

[edit] Article Licensing

Hi, I've started a drive to get users to multi-license all of their contributions that they've made to either (1) all U.S. state, county, and city articles or (2) all articles, using the Creative Commons Attribution-Share Alike (CC-by-sa) v1.0 and v2.0 Licenses or into the public domain if they prefer. The CC-by-sa license is a true free documentation license that is similar to Wikipedia's license, the GFDL, but it allows other projects, such as WikiTravel, to use our articles. Since you are among the top 2000 Wikipedians by edits, I was wondering if you would be willing to multi-license all of your contributions or at minimum those on the geographic articles. Over 90% of people asked have agreed. For More Information:

To allow us to track those users who muli-license their contributions, many users copy and paste the "{{DualLicenseWithCC-BySA-Dual}}" template into their user page, but there are other options at Template messages/User namespace. The following examples could also copied and pasted into your user page:

Option 1
I agree to [[Wikipedia:Multi-licensing|multi-license]] all my contributions, with the exception of my user pages, as described below:
{{DualLicenseWithCC-BySA-Dual}}

OR

Option 2
I agree to [[Wikipedia:Multi-licensing|multi-license]] all my contributions to any [[U.S. state]], county, or city article as described below:
{{DualLicenseWithCC-BySA-Dual}}

Or if you wanted to place your work into the public domain, you could replace "{{DualLicenseWithCC-BySA-Dual}}" with "{{MultiLicensePD}}". If you only prefer using the GFDL, I would like to know that too. Please let me know what you think at my talk page. It's important to know either way so no one keeps asking. -- Ram-Man (comment| talk)

[edit] Double bass picture?

Hi Andrew,

I noticed you uploaded Image:AGK bass bow grip.jpg, and then replaced it with a lower-resolution version. But neither version is very high-res. I was just wondering, do you still have the original, camera-resolution version lying around somewhere? If so, could you upload it please? Higher resolution is always better!

Thanks, dbenbenn | talk 03:48, 26 Jan 2005 (UTC)

P.S. Same goes for Image:AGK bass bow.jpg. dbenbenn | talk

[edit] Topological vector spaces

Hi,

I have found your name on a few topological vector space articles. I am currently working on some of those articles but I would not call myself an expert on the material. It would be nice you could check for any obivious errors on my part (for example locally convex space). Comments are always welcome.

Thanks. MathMartin 19:47, 10 Apr 2005 (UTC)

[edit] E

I think I fixed your flippant edit with a flippant remark, so apologies for that. There are indeed rather a lot of 10 digit primes but proportionally very few, but I'm sure you know that. Thanks for all your hard work! Agentsoo 12:45, 20 Jun 2005 (UTC)

[edit] MetaPost edit

Oops! You're right, I was using a script to automatically fix up some common typos/misspellings. It was under human supervision (ie mine), but I guess this one slipped under the radar. Sorry!

PS: Interesting articles, keep up the good work. Cmdrjameson 01:04, 25 November 2005 (UTC)

[edit] Metapost image

Hi! I was translating the article about Metapost programming language to Spanish and I needed your picture about the examples. Since I found it under the public domain I uploaded to Wikimedia Commons. Of course, I wrote your name as the author of the work.

I hope you don't mind.

Thanks, anyway, for your picture.

[edit] SVGs after your PNGs

Hi! I'm just letting you know that I'm creating SVG files (with Inkscape) after your PNG files made with makepolys.c. Here's an example. Ciao! – Tintazul msg 12:48, 13 October 2006 (UTC)

[edit] Request for e-mail

Andrew Kepert, please send me an e-mail at xxxxxx@teacher.com. I have a question to ask you regarding polyhedra, but I can't post the question here. I tried to e-mail you from your user page, but that didn't work, as you had no e-mail address stored on Wikipedia. Thanks.... RobertAustin 16:38, 12 November 2006 (UTC)

[edit] Double bass copyright email

Any response from your e-mail? -- ßottesiηi (talk) 20:17, 21 November 2006 (UTC)

Yeah, it doesn't really bother me all that much. I take the GFDL almost as public domain anyways, I'm not a big copyright fan. Wikipedia:Standard GFDL violation letter is a useful source. -- ßottesiηi (talk) 00:28, 23 November 2006 (UTC)

Hi, thanks for your posting, but sorry I don't understand all of your numerous ACRONYMS! Can you explain those? Badagnani 20:32, 22 November 2006 (UTC)

[edit] Polyhedra images

Hello! In the past, you did some nice images of polyhedra which I'm using for the article de:Spielwürfel (Dice) in the German Wikipedia. When you scroll through the article (I don't know whether you can read German, but it's just about the pictures ;)) you will see that for some of the more obscure dice there are no schematics. Could you be bothered to create them? I hope to get the article featured in the German Wikipedia (and maybe translate it later to replace the inferior English one) and completeness in images would be very useful in achieving this goal. If you are willing to help, I could supply an English list of the missing polyhedra, of course. Traitor de 18:07, 25 December 2006 (UTC)

In reply to

Hi Traitor,

WRT en:User_talk:AndrewKepert#Polyhedra images for the dice pages -- sorry, I don't really have time. The povray code for the images (a version of which is available via my user page) was originally written by en:User:Cyp and relied on polyhedra having only one edge-length -- it uses these to detect edges and then faces, if I recall. So it worked for archimedean and Johnson solids. (Oh and archimedean duals via a dual transformation.) So it would be nontrivial for me to hack it up to handle the dice on your page. Maybe you could get a version of it to work where you explicitly provided the vertices, edges and faces. Otherwise you could try Cyp.

Cheers, 134.148.4.20 04:47, 2. Jan. 2007 (CET)

Thanks for your answer. I guess I have to wait and hope that Cyp will be active again. Traitor de 00:07, 6 January 2007 (UTC)
