You archived! \o/

First post on a fresh page! Thank you for going against your principles for the good of those on slow connections/computers :-P And thanks for the image, it's lovely... you inspired me to make my own! — Editor at Large^(speak) 18:50, 22 February 2007 (UTC)

Ooo, your image is even prettier. :-) Regarding archiving, I figured a more effective way of protesting wikithreads that wouldn't penalise innocent dial-up users would be to post an essay on the topic and see how I can get involved with efforts to improve them. Thanks for writing. :-) Deco 19:23, 22 February 2007 (UTC)

Explaining the obvious

I like your edit on the Condom page. It's good to make things clear. Especially on this sort of topic, where some people who aren't sure may be embarassed to ask. --Coppertwig 17:35, 25 February 2007 (UTC)

Welcome to VandalProof!

I fixed the approval bug from last night. Betacommand ^{(talk • contribs • Bot)} 15:53, 26 February 2007 (UTC)

Check it out

Check out codecodex. --Ideogram 11:33, 28 February 2007 (UTC)

Thanks for the link. I think a lot of these are going to pop up. I need to come up with a plan to avoid fragmentation of effort. Hmm. Deco 04:13, 1 March 2007 (UTC)

Survey Invitation

Hi there, I am a research student from the National University of Singapore and I wish to invite you to do an online survey about Wikipedia. To compensate you for your time, I am offering a reward of USD$10, either to you or as a donation to the Wikimedia Foundation. For more information, please go to the research home page. Thank you. --WikiInquirer 01:27, 4 March 2007 (UTC)^{talk to me}

P and NP

OK, I see now that I read your edit summary too fast. The statement should still not be there, at least not in that form. ("Trivially easy to crack"? Who found that out?) Even if the wording were repaired, it's unencyclopedic chatter and speculation; doesn't really belong in an encyclopedia article. --Trovatore 02:55, 10 March 2007 (UTC)

Although it might seem odd to put so much attention on a problem not known to be complete, the connection between P=NP and factoring and RSA cryptography is quite frequently mentioned in publications on it, including these lecture notes and Stephen Cook's official description of the Millenium Prize problem. I think it deserves some kind of mention - why not just quote Stephen Cook? No greater authority than that. Deco 06:33, 10 March 2007 (UTC)

Hi Deco,

I've recent had some time to devote to convert some old programs I previously wrote as standalone programs for personal computers to run as distributed programs suitable for utilization by multiple computers via the Internet.

To get started I posted a question on the science desk requesting collaborative assistance to develop a distributed data packet protocol with the result of receiving an excellent response from a user and consequently adapting his modified suggestion as the core payload of the distributed program data packet protocol.

Packet protocol, however, is dynamic at this stage while the program is being converted and even though I can continue seeking program conversion collaboration by posting questions on the science/computing desks I was wondering if you might be interested in helping to fast track the conversion from standalone to distributed in light of the time it would most likely take to explain the algorithm to non or elementary programmers.

If you would be interested please let me know. Diligent 15:51, 10 March 2007 (UTC)

My experience in distributed processing, and particularly massively distributed processing, is quite limited. I'm afraid I couldn't be of assistance, and would have trouble finding the time if I could be. Deco 20:09, 10 March 2007 (UTC)

The project itself seems right up your alley having an interest in P and NP (above) and all that. If you change your mind please let me know. Thanks. Diligent 01:36, 11 March 2007 (UTC)

Hello

Hello, Deco, just decided to leave a message on your talk page.. I must say, looking at your User Page, you appear to be an expert on programming and code :P .. I'm not too good at it, even a bit of wiki-code I cannot understand :P .. Anyway, in our chat in IRC, you said you were a member of many wikipedia languages, so (this is JUST an idea, friendly advice), perhaps you should add like [[es:User:Illyria05]] to the bottom, so people who wander around (like me) on different wikipedias can see what wikipedias you are associated to.. Again, just some friendly advice... :) Leave me a message on my talk page if you want.. Illyria05 (Talk • Contributions) 07:34, 11 March 2007 (UTC)

Hi Illyria05, thanks for writing! Feel free to ask me for help with admin stuff any time. Hmm, interwiki links, that sounds like a great idea. Take care! Deco 07:45, 11 March 2007 (UTC)

Hello, please do not operate bots on HE WP without checking first and obtaining a bot flag. Your bot was blocked and all its edits were reverted, becaude it deleted section names and introduced other errors. Odedee 05:56, 21 March 2007 (UTC)

I'm sorry, I didn't realise the bot was causing problems or that HE requires obtaining a bot flag. Please unblock my username and I won't run automatic processes on HE in the future. Dcoetzee 06:34, 21 March 2007 (UTC)

edits to Wikipedia:Fromowner

Could you remove them? I made sure that the image stay PD precisely so there was no need to credit so all the things like Wikipedia:Fromowner stayed clean and focused on function.Geni 02:19, 25 March 2007 (UTC)

I think it's important for people who want to find more information about the image - it seems reasonable to suppose that at least some people clicking on the image do so with the intention of finding out more about it, rather than about uploading. I can deemphasise it with small tags. Dcoetzee 02:27, 25 March 2007 (UTC)

then they can try visting the talk page. The vast majority will not be and those that will will likely consider the talk page (and Image:Male no free image yet.png isn't original and is on en rather than commons).Geni 02:31, 25 March 2007 (UTC)

I think the proportion of people interested in the image itself is larger than you think. I for one didn't even think of looking at the talk page. And the information I added to the image page is hidden by the redirect and only visible in the wikitext. I don't see any easy way for anyone to find this info right now if that link is missing. Dcoetzee 02:36, 25 March 2007 (UTC)

The talk page contains a link to Wikipedia:Fromowner documentation which covers pretty much everthing.Geni 02:39, 25 March 2007 (UTC)

It's good that there's a page for that, and that it's linked from somewhere, but I honestly don't think people looking for that info will look there. It's not the logical place to look. I didn't look there. I don't think a single link excessively complicates or clutters the interface. If you want to further minimize its visual impact in some way I have no problem with that. Dcoetzee 02:43, 25 March 2007 (UTC)

Fire safety and daylight saving time

The change log for your recent edit to Daylight saving time says "any biannual activity could be used as a reminder". While that's true, it's also true that fire safety officials do use daylight-saving changes to remind citizens. Officials do not use any other semiannual or annual event as far as I know. Residential fires cause about 3,000 deaths per year in the U.S., so a brief mention in the intro of this common use of DST does not seem out of place.

If the previous wording didn't seem quite right, how about adding the following to the intro instead, as a new first sentence in the last paragraph? "Fire safety officials suggest using DST's clock shifts as reminders to replace batteries in smoke detectors and review fire escape plans. However,…" Eubulides 05:17, 26 March 2007 (UTC)

I think this placement makes it sound like it's describing an advantage or disadvantage of Daylight Saving Time, which it really isn't, it's more just related to it. I'd prefer a sentence at the end of the intro, if anything. Dcoetzee 09:17, 27 March 2007 (UTC)

Wavy Lines?

There are questions about the wavy lines in the graph you drew for the Optimal substructure and Dynamic programming articles. It would be great if you could stop by and answer them. -- Mikeblas 09:46, 31 March 2007 (UTC)

Image:Carl Hiaasen.jpg

It's been a while ago you uploaded this image, but I just wanted to inform you I put a {{Replaceable fair use}} tag on it. Garion96 (talk) 19:19, 4 May 2007 (UTC)

That sounds fine. You could probably say the same of the other photos from the same photographer. Fair use wasn't so strictly enforced in those days. Dcoetzee 00:04, 5 May 2007 (UTC)

Ok, I did that. It is too bad really, but perhaps now someone will find a 100 procent free content image. Also, you might want provide a source on Image:DavidAndGoliath.jpg. Otherwise OrhanBot will eventually find it and tag it as having no source. Garion96 (talk) 10:14, 5 May 2007 (UTC)

Possibly unfree Image:Pademelon.jpg

Mathematics CotW

hey Dc, I am writing you to let you know that the Mathematics Collaboration of the week(soon to "of the month") is getting an overhaul of sorts and I would encourage you to participate in whatever way you can, i.e. nominate an article, contribute to an article, or sign up to be part of the project. Any help would be greatly appreciated, thanks--Cronholm144 21:00, 13 May 2007 (UTC)

Fair use rationale for Image:11SSShield.svg

Thanks for uploading Image:11SSShield.svg. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in Wikipedia articles constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image 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 'image' 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 "Image" from the dropdown box. Note that any fair use images uploaded after 4 May, 2006, and 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.

Hi There

I am a British Lit doctoral student with a masters in classics and 18th century politics/history/society. I've recently got into a few scuffles. One was based on a few people taking offense to my user page (I find the page hillarious, and tried only to quote things that are interesting from the wiki project), and over the creation of another page. I originally created a page to deal with the Warhammer 40,000 universe's cross over/cross promotion campaign between its comic series and its miniature war game. The wiki page is here and you can look through it. It seems that people disagreed with my original project and wanted to make it a page just discussing comics (even though the individual comics have their pages discussing such. I have continued working on the original project, and it can be found here. If you would like to look it over, tell where it should be expanded, that would be a great help. Its about 60% done now. If the other individuals are unwilling to let my version become the page, then I will probably chop up the critical review sections, put them in their individual comics section, and then have a page titled "cross over (warhammer 40,000)" or something similar. (I prefered the original name "Graphic Novels (Warhammer 40,000)" because it was clean and too the point, but, if you look over there, that would be impossible to attain now. But yeah. If you could look at my user sandbox version, that would be great. SanchiTachi 03:41, 27 May 2007 (UTC)

David and Goliath image?

Hello, Dcoetzee. I am searching for the source of an image currently existing in the English Wikipedia, Image:DavidAndGoliath.jpg. A copy of this image used to be in Sling (weapon), but that copy has now been removed from the Commons due to lack of proper source information. The person who uploaded it to the Commons, tells me he copied your image. Therefore I am now asking you where you found it. It is listed on your user page under the heading "Not created but uploaded by me" and there is no source information on the image page. So did you upload a digitized photo that you found somewhere? Did you scan it from a magazine or a book? Something else? I would really like to find proper information about this photo, and add it to the image page, so that the image does not vanish again. Thanks! — SWWright^Talk 20:11, 5 June 2007 (UTC)

I just found it on the web somewhere. It was much too long ago to remember where. It really ought to be deleted unless someone can establish its source. Dcoetzee 20:30, 5 June 2007 (UTC)

Uh, yeah, well, that's what I'm trying to do... Guess I'd better save a copy of the image, in case it vanishes again while I'm trying to track it down. — SWWright^Talk 03:39, 6 June 2007 (UTC)

Primorials

saw your comment on this - I have no interest in defending anymore against PrimeHunter but if you have interest, I will post my source/exe hopefully this w/e at my Talk page. You'd have to see the entire discourse - aside from any wiki content, which I have never asked for, my Conjecture works bang-on despite what anyone else says. The pgm is in C++, I code for myself so will try to add some annotation but I do try to be rigorous, in that I wouldn't have submitted the sequence to OEIS until it had proved out. Tried emailing the other fella, he has no interest but email me, visit my wiki page as you see fit. I have a cohort Phil Dempster (invented the BodPod) looking my stuff over, but it is really a self-proving sort of thing - it either works or it doesn't. Thus, I was missing 2 numbers in the sequence, and so was miscategorizing a single prime thru 10^6. Once corrected. all is fine. Of course feel a bit bruised in the only commentary being fairly condescending (sp.), but the proof's in the pudding. Thanks for your time ...--Billymac00 17:57, 9 June 2007 (UTC)

My mistake. I wished to oppose your position, not to support it. Dcoetzee 21:12, 9 June 2007 (UTC)

Non-free use disputed for Image:Zelda_1_Peahat.gif

This file may be deleted.

Thanks for uploading Image:Zelda_1_Peahat.gif. However, there is a concern that the rationale you have provided for using this image under "fair use" may be invalid. Please read carefully the instructions at Wikipedia:Non-free content and then go to the image description page and clarify why you think the image qualifies. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If it is determined that the image does not qualify under fair use, it will be deleted within a couple of days according to our Criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you. ShakespeareFan00 08:44, 23 June 2007 (UTC)

Deterministic algorithm : what's the little story ?

Hello

You seem to have written there about cheating at blackjack by guessing the deck. I put a notice there for citation, because no proof is given, but also because I'd would enjoy reading more about this :). Where did you get this from ? --Zogromalvus 01:19, 1 July 2007 (UTC)

Hi, I'm afraid your mistaken - I wasn't the one who added this particular fact, although I may have edited it. Sorry! Dcoetzee 02:41, 2 July 2007 (UTC)

Ok, I guess from (diff) that you copied it from somewhere else, or I'm reading bad. Could you tell where you got that from, if it's not too old. The trouble is I feel like this particular information may be erroneous, because I saw on TV, and [1] is about it, that people from MIT trained themselves guessing a casino blackjack deck, by using a well designed method, which involved counting the cards and probability, and needed few people to work. But I don't think this is the same as guessing a deck generated by a computer with a random generator number, and I didn't find anything about that, which is rather curious. --Zogromalvus 15:54, 2 July 2007 (UTC)

Hmm, maybe I did write it. I believe the article is accurate but you misunderstood it - real decks aren't shuffled using well-known pseudorandom number generators, but "virtual" decks on online gambling sites certainly are, and because they use a PRNG they can be anticipated in advance (see for example this link, which I will add as a citation). Dcoetzee 20:32, 2 July 2007 (UTC)

I did understand well, but I didn't find any facts about that, and I supposed it could be a confusion with what I knew, that would have gotten worse and worse with copy/paste (Chinese whispers). --Zogromalvus 21:38, 2 July 2007 (UTC)

I certainly didn't mean any insult - this statement needed a citation and now has one and the article is improved. Thanks for bringing it to my attention. :-) Dcoetzee 21:52, 2 July 2007 (UTC)

Unspecified source for Image:Sade-Best_of_Sade.jpg

Thanks for uploading Image:Sade-Best_of_Sade.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 {{GFDL-self}} tag can be used to release it under the GFDL. If you believe the media meets the criteria at Wikipedia:Fair use, use a tag such as {{non-free fair use in|article name}} or one of the other tags listed at Wikipedia:Image copyright tags#Fair use. See Wikipedia:Image copyright tags for the full list of copyright tags that you can use.

If you have uploaded other files, consider checking that you have specified their source and tagged them, too. You can find a list of files you have uploaded by following this link. Unsourced and untagged images may be deleted one week after they have been tagged, as described on criteria for speedy deletion. If the image is copyrighted under a non-free license (per Wikipedia:Fair use) then the image will be deleted 48 hours after 02:25, 8 July 2007 (UTC).

Dynamic Array

Dear Dcoetzee, thank you for expressing interest in the topic of dynamic array. I can explain my reasons for the revert. Whether dynamic array is array or not depends on point of view. I think the best way to contrast fixed sized arrays and dynamic arrays is focus on properties of each data structure. The original overview section started off with some motivational material that demonstrated the reason for dynamic array's existence. Your edit moves that material to a later point in the topic, and jumps into technical discussions before the background is laid out. One final issue deals with the cost of expanding the dynamic array. When n element sized array is expanded to 2n, in principle only n additional memory space need to be allocated, and this is an order n operation. When amortized over the entire range of n additions, the resize operation becomes order 1, which is already described in the 'amortized analysis' section. Best Regards, MegaHasher 04:35, 1 August 2007 (UTC)

You still don't understand the n² thing - that was intended as motivational material. The point is that this is how much it costs to greedily expand the array one element at a time, which motivates resizing it by a larger amount. I wrote the amortized analysis section and already understand it - please don't be pedantic.

I understand your desire to discuss motivation up front, but my goal was to expand on the motivation and make it clearer, not to remove it. I did add too much detail perhaps. I'll try to edit this again, please take another look when I'm done.

I'll ignore the issue of whether it's an array or not as I'm okay with the current wording. Dcoetzee 04:42, 1 August 2007 (UTC)

Please explain Collection classes

hello what is a collection classes and how should i actually code it in my project

do you have a sample code

A collection class is a class that stores some collection of values, such as the numbers 1, 2, 5, and 7, or a set of strings. There are various types of collections for different purposes that allow different operations, many of which are listed at List of data structures. You should generally not code collection classes but use the existing ones supplied by your environment, which should be documented in your language's online documentation.

Wikimania in Atlanta!

Hi! I noticed your involvement on U.S. South-related articles, categories and WikiProjects, and I wanted to let you know about a bid we're formulating to get next year's Wikimania held in Atlanta! If you would like to help, be sure to sign your name to the "In Atlanta" section of the Southeast team portion of the bid if you're in town, or to the "Outside Atlanta" section if you still want to help but don't live in the city or the suburbs. If you would like to contribute more, please write on my talk page, the talk page of the bid, or join us at the #wikimania-atlanta IRC chat on freenode.org. Have a great day!

P.S. While this is a template for maximum efficiency, I would appreciate a note on my talk page so I know you got the message, and what you think. This is time-sensitive, so your urgent cooperation is appreciated. :) Mike H. I did "That's hot" first! 09:36, 31 August 2007 (UTC)

Hi Mike. As you know I no longer live in Atlanta, so I'm not terribly motivated to get it coming there. Sorry. :-) Dcoetzee 22:13, 31 August 2007 (UTC)

Image source problem with Image:Nancy Sinatra-Movin with Nancy Soundtrack.jpg

Image Copyright problem

Thanks for uploading Image:Nancy Sinatra-Movin with Nancy Soundtrack.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, 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, 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 {{GFDL-self}} tag can be used to release it under the GFDL. If you believe the media meets the criteria at Wikipedia:Non-free content, use a tag such as {{non-free fair use in|article name}} or one of the other tags listed at Wikipedia:Image copyright tags#Fair use. See Wikipedia:Image copyright tags for the full list of copyright tags that you can use.

If you have uploaded other files, consider checking that you have specified their source and tagged them, too. You can find a list of files you have uploaded by following this link. Unsourced and untagged images may be deleted one week after they have been tagged, as described on criteria for speedy deletion. If the image is copyrighted under a non-free license (per Wikipedia:Fair use) then the image will be deleted 48 hours after 09:23, 7 October 2007 (UTC). If you have any questions please ask them at the Media copyright questions page. Thank you. —Angr 09:23, 7 October 2007 (UTC)

Replaceable fair use Image:Elaine Paige Tour Programme 2004.jpg

Replaceable fair use

Thanks for uploading Image:Elaine Paige Tour Programme 2004.jpg. I noticed the 'image' page specifies that the image is being used under fair use, but its use in Wikipedia articles fails our first fair use criterion in that it illustrates a subject for which a freely licensed image could reasonably be found or created that provides substantially the same information. If you believe this image is not replaceable, please:

1. Go to the image description page and edit it to add {{di-replaceable fair use disputed}}, without deleting the original Replaceable fair use template.
2. On the image discussion page, write the reason why this image is not replaceable at all.

Alternatively, you can also choose to replace the fair use image by finding a freely licensed image of its subject, requesting that the copyright holder release this (or a similar) image under a free license, or by taking a picture of it yourself.

If you have uploaded other fair use media, consider checking that you have specified how these images fully satisfy our fair use criteria. You can find a list of 'image' pages you have edited by clicking on this link. Note that even if you follow steps 1 and 2 above, fair use images which could be replaced by free-licensed alternatives will be deleted 2 days after this notification (7 days if not used in an article), per our Fair Use policy.

League of Copyeditors roll call

Greetings from the League of Copyeditors. Your name is listed on our members page, but we are unsure how many of the people listed there are still active contributors to the League's activities. If you are still interested in participating in the work of the League, please follow the instructions at the members page to add your name to the active members list. Once you have done that, you might want to familiarise yourself with the new requests system, which has replaced the old /proofreading subpage. As the old system is now deprecated, the main efforts of the League should be to clear the substantial backlog which still exists there. The League's services are in as high demand as ever, as evinced by the increasing backlog on our requests pages, both old and new. While FA and GA reviewers regularly praise the League's contributions to reviewed articles, we remain perennially understaffed. Fulfilling requests to polish the prose of Wikipedia's highest-profile articles is a way that editors can make a very noticeable difference to the appearance of the encyclopedia. On behalf of the League, if you do consider yourself to have left, I hope you will consider rejoining; if you consider yourself inactive, I hope you will consider returning to respond to just one request per week, or as many as you can manage. Merry Christmas and happy editing, The League of Copyeditors.

If you think that this notice was placed here in error, you may contest the deletion by adding {{hangon}} to the top of the page (just below the existing speedy deletion or "db" tag), coupled with adding a note on [[ Talk:Image:Blackboard bold.png|the talk page]] explaining your position, but be aware that once tagged for speedy deletion, if the article meets the criterion it may be deleted without delay.

Comment on your primality certificate article

Hi Deco, thanks for writing this up. This is just a quick note suggesting you source "Although not the first primality proof invented" in Primality certificate. I'd be very interested in seeing anything earlier written about even long proofs of primality.

In hindsight one can say that it is so obvious that any failed computation of a deterministic search for a factor can serve as such a proof that it must surely have at least been a folk theorem that there were exponentially long proofs. However I'm not aware of anyone having accorded that approach to proving primality even that status, let alone an actual written claim to that effect. To the best of my knowledge my primality prover was the first documented primality proof system of any kind. The whole concept of primality proofs simply didn't exist prior to my paper (which I first wrote up in 1973 though I had the result in 1972), though it certainly could have if anyone had thought to bring it up. --Vaughan Pratt (talk) 04:09, 28 March 2008 (UTC)

One other minor point: the original paper, which can be seen at http://boole.stanford.edu/pub/SucCert.pdf, gives an upper bound of O(log³(n)log log n) for the time required to check the proof on a random access machine (with an additional log log log n factor for a Turing machine), based on Schönhage-Strassen, the best available multiplication algorithm in 1975, considerably less than the O(log⁵(n)) in your writeup, which otherwise is spot on. --Vaughan Pratt (talk) 04:43, 28 March 2008 (UTC)

Thank you for your feedback, it's quite an honour to have my article reviewed by Vaughan Pratt himself! I don't know why I claimed "not the first primality proof invented" - proofs requiring exponential time verification aren't all that useful when you might as well take the prime as the certificate and have the verifier perform trial division. I probably just lacked insight about the historical context of the work and I apologise for the error. You're also right that my analysis was terribly imprecise - my original point was just to show that you didn't need any complex algorithms or analysis to achieve polynomial-time verification, but it's also important to describe the best-known bounds, and Schönhage-Strassen can be treated as a black box. I also expanded on the explanation bounding the size of the tree, since I was handwaving that. Thanks again, I really appreciate your feedback. Dcoetzee 20:11, 28 March 2008 (UTC)

While I was at it I added a bit of info on Atkin-Goldwasser-Kilian-Morain certificates. :-) Dcoetzee 22:46, 28 March 2008 (UTC)

The changes look great, thanks for making them. Concerning the difficulty of factoring n−1, this is indeed a drawback of my approach if one wants a method that can reliably generate a certificate for any prime, the problem addressed by AGKM. However if the goal is merely a large supply of certified primes then I'm aware of at least two strategies for efficiently producing Pratt certificates and producers of certified primes may well know of more. The naive one is based on the considerable variability of difficulty in factoring large numbers: simply abandon attempted factorizations that go over some time limit, or alternatively run many in parallel and take whatever proofs turn up. The second strategy is to generate a supply of "somewhat" smaller (say a fifth to half as long as the desired final certified prime) certified primes, and in parallel apply the Strassen-Solovay or Rabin probabilistic test to one plus various products of these and whenever a prime is encountered complete the proof (which is now very easy since it involves no factorization). That said, I consider any number that "looks" prime according to a probabilistic test to be as adequately certified for all practical purposes as one "perfectly" certified by these "ideal" methods (but I don't consider myself an expert in applications of certified primes). --Vaughan Pratt (talk) 00:54, 29 March 2008 (UTC)

Those are actually really interesting ideas - and they seem like they could be applied recursively to construct arbitrarily large primes with proofs. However I wasn't able to find a specific citation for these and it would be original research to add them without one. Could you provide one? Thanks again for your help.

You probably do not remember me. You wrote a C++ version of a sort algorithm which took me a surprising number of years to develop through the process of trying to minimize the Metzner-Shell sort as I recall.

I began thinking in the early sixties of a way for a computer to reach a conclusion about whether God existed or not. The results turned out to be a program which reduces multiple state logical equations to minimum form. Developing the program to the point where it would satisfy proof of concept burned me out and left the program unfinished without a front end. The program can be used without a front end but a front end would make it possible for anyone to create a decision table and form the logical equations but more importantly would hopefully be able to automate construction of the decision table and formulation of equations.

I've completed another program which implements an algorithm to optimize a classification table. Since I repaired refrigeration equipment and computers a natural use for the program is to optimize troubleshooting charts. What I want to do is to apply the program to both medicine and law and these applications also require a front end to convert legal verbiage to logical elements and their characteristics and characteristic states.

Long story short I was wondering if you might be interested in developing front ends to create decision tables for the logical equation reduction program and classification tables for the optimization program. The front ends need do little more than to ask the user to enter values which define characteristics of the elements, whereas an automated version would have to figure this out for itself. The challenge then is creating an intelligent front end. 71.100.13.197 (talk) 08:32, 21 April 2008 (UTC)

Hi, thanks for your note. I'm afraid my obligations don't permit me to get involved in a new project like this right now, but I wish you luck. Dcoetzee 20:34, 21 April 2008 (UTC)

Okay, there is no rush in completing this project on my part, since as I said I am truly burned out and my main goal has been long since satisfied which was only proof of concept. However, since you are an administrator I might also mention to you that both programs can be applied to Wikipedia policy for the benefit of both user and administrator alike, especially in the construction and evolution of the rules. The advantage of their use would be to reduce or eliminate misinterpretation of the rules which seems very common now-a-days with so many new administrators using the rules as virtual excuses to accomplish some personal agenda or goal. Also I might add that most, if not all, parts of both programs can take advantage of a parallel machine. Have a nice day. 71.100.13.197 (talk) 22:12, 21 April 2008 (UTC)

Thanks

Basically what's made me discontent with the project lately is it's vulnerability to vandalism. I've begun to view that what would be best for the project would be for account creation to be required and for an email address to be required as well. This would certainly deter petty vandalism, but I know it is a controversial stance, as Wikipedia (falsely in my opinion) believes that its success is due to anyone being able to edit without registering. But as they are unwilling to even try requiring account creation for a period of time, we'll never know whether requiring account creation is truly responsible for Wikipedia's success or not. I used to be a vandal fighter, but I've given up on that after realizing that it was a waste of my time when Wikipedia could fix vandalism by simply requiring account creation and an email address. Anyway that's what has been making me discontent lately.--Urban Rose 05:06, 10 May 2008 (UTC)

Image source problem with Image:DavidAndGoliath.jpg

Image Copyright problem

Thanks for uploading Image:DavidAndGoliath.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, 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, 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 {{GFDL-self}} tag can be used to release it under the GFDL. If you believe the media meets the criteria at Wikipedia:Non-free content, use a tag such as {{non-free fair use in|article name}} or one of the other tags listed at Wikipedia:Image copyright tags#Fair use. See Wikipedia:Image copyright tags for the full list of copyright tags that you can use.

If you have uploaded other files, consider checking that you have specified their source and tagged them, too. You can find a list of files you have uploaded by following this link. Unsourced and untagged images may be deleted one week after they have been tagged, as described on criteria for speedy deletion. If the image is copyrighted under a non-free license (per Wikipedia:Fair use) then the image will be deleted 48 hours after 22:08, 12 May 2008 (UTC). If you have any questions please ask them at the Media copyright questions page. Thank you. 87.1.118.9 (talk) 22:08, 12 May 2008 (UTC)

Copyedit request

Hello, I am contacting you because you're a member of the League of Copyeditors. Would you be interested in taking a look at Highlander: The Series (season 1) which is currently a Featured List Candidate ? The quality of the prose is the only remaining objection to its promotion and I would really appreciate your help. Have a nice day, Rosenknospe (talk) 12:57, 17 May 2008 (UTC)

No problem. Dcoetzee 02:11, 18 May 2008 (UTC)

Thank you so much for doing it, and so quickly ! And I really like your prose, too. You have greatly improved that list. I'm thinking about reintroducing the paragraph about star billing, but I can't think of a way to do it right now, so I'll give it some time. I'm really grateful and if I can return the favor (no copyediting though ;), please let me know. Have a nice day, Rosenknospe (talk) 15:42, 19 May 2008 (UTC)

Pronunciation task force

Hi! I was meaning to comment when you first put your proposal at WP:SPOKEN, but real-life busy-ness took over. I was going to say: excellent idea, and sounds similar to a mini-project I put together for pronunciations of British place names. It has been moribund since an early flurry of activity; perhaps it could be absorbed into the task force? The link is here: Wikipedia:WikiProject UK geography/Embedded Audio Pronunciations. All of the pronunciations I have added have been uploaded to Commons in a standard naming format.

Anyway, must go now, but I will add my name to the list and take a closer look tonight. As a regular contributor of full spoken articles, I have the facilities and time to provide pronunciation files on just about any topic, so I'm looking forward to being able to help in any way! Hassocks5489 (tickets please!) 07:54, 27 May 2008 (UTC)

Hi, and thanks for your interest! I like your idea of absorbing the UK geography project - they're great existing examples and I'm taking the liberty of adding them to Category:Articles including recorded pronunciations (UK English). Feel free to add Category:Requests for audio pronunciation (UK English) to other UK place names and people (I'm using this category hierarchy as the task force's "to do" list). Thanks for joining and I'll be happy to hear any other feedback you have. Dcoetzee 09:13, 27 May 2008 (UTC)

Spoken pronunciations

Hi. I wanted to ask if you could record a spoken pronunciation of "Newcastle-upon-Tyne" is the way in which it is spoken by Novocastrians (and a good proportion of people elsewhere) i.e. newCASSul. There is a "southern English" pronunciation (NEW-caah-sul) in the article at present, but it would be better to replace this with the "correct" pronunciation, or better still, include both with a note that the second is how (some) people with southern English regional accents pronuounce it. SP-KP (talk) 18:07, 27 May 2008 (UTC)

Hi SP-KP - although I could do this recording, I am myself an American and I feel it would be best for a British person to record this name (preferably one from the city in question). You might contact User:Hassocks5489 with this request. Another thing you can do is modify the text yourself to note the two pronunciations, then add the article to Category:Requests for audio pronunciation (UK English) so that someone will record the other one. Hope this helps! Dcoetzee 22:28, 27 May 2008 (UTC)

(Also copied to SP-KP's talk page) I did the "NEW-caah-sul" version in question. I deliberately didn't attempt the local pronunciation because I thought I couldn't really achieve the accuracy and authenticity required (although I consider myself able to make passable or good attempts at most British accents). Unfortunately, since the conversation we had at the time I uploaded the file, nobody has uploaded a local version. Perhaps if I record two or three versions and upload them, SP-KP may be able to help by identifying the best one or providing guidance for me to get it sounding as accurate as possible? I don't mind making several attempts at getting it right; I would rather have both pronunciations featured on the article than just the RP one we have at the moment. Hassocks5489 (tickets please!) 07:57, 28 May 2008 (UTC)

A toughie for pronunciation

Heres a puzzler for you. While I was filling the request for pronouncing "Dr. Suess", I found there's the Americanized pronunciation we're all familiar with "/ˈsuːs/" (Soose), and the correct German pronunciation "/ˈsɔɪs/" (Soice). I recorded using both "Theodor Soose Geisel OR Theodor Soice Geisel. I'm torn on whether or not to use this, or split into 2 using EN and GE distinctions. What do you think? Reason turns rancid (talk) 13:03, 8 June 2008 (UTC)

Hi Reason, thanks for your contribution. Since IPA are included for both, I think it's likely that both will be useful, add both to the page, and let the page authors decide which they want to keep. Dcoetzee 21:18, 9 June 2008 (UTC)
