Yes, already
Hi. There's a question at MCQ that I'm worried is going to archive without answer. Can you help or point me to somebody who might? Media copyright questions --Moonriddengirl (talk) 14:48, 8 November 2009 (UTC)
 * Done, hope it helps. :-) Dcoetzee 07:14, 9 November 2009 (UTC)
 * Thank you! And here I am again, cluttering your clean page. It looks like WP:CCI may go live soon. I've got a question about the ContributionSurveyor program at its talk page. Your input, I expect, would be invaluable. :) --Moonriddengirl (talk) 18:58, 9 November 2009 (UTC)
 * Hmm, could you point me to the specific question? I didn't spot it. Maybe you linked to the wrong section? Thanks. :-) Dcoetzee 06:15, 15 November 2009 (UTC)

Article Rescue Squadron invitation
I loved your article Criteria for speedy deletion/Overturned speedy deletions and mentioned it here: Wikipedia talk:Article_Rescue Squadron How did you gather that information from the deletion log? What tools did you use? Please give me as much details as possible, because I would love to mimic your study.

You maybe interested in a project I am a member of.

Copyright problems?
Hi. Interceptor pattern is tagged as a copyvio of, apparently based on the tables. I'm not able to assess the creativity of that material, hence its usability. Can you take a look? On a related note, there is an outstanding section on whether "instruction sets" are copyrightable at WT:CP. Um, ? --Moonriddengirl (talk) 14:13, 14 November 2009 (UTC)
 * Hey. :-) It looks like a clear copyvio to me. Compare page 8 of the slides with the intro paragraph. To a lesser extent page 16 resembles the second paragraph. The example is also clearly lifted directly from the slides - compare pages 23-28 to the code in example section, they're identical. I'll comment on CP. :-) Dcoetzee 06:28, 15 November 2009 (UTC)

Commons deletion debate?
Hi. Has this one been archived without closure, do you think? It's been sitting there for an awfully long time. :/ --Moonriddengirl (talk) 13:40, 23 November 2009 (UTC)
 * Nope. Commons always has a really long deletion backlog. See Commons:Commons:Deletion requests/2009/08/13. I should probably help clean it up sometime. :-) Dcoetzee 18:25, 24 November 2009 (UTC)

WP:CANVASS addition
Hi there. Regarding your addition to WP:CANVASS here, I agree with this addition. Good thinking, and good phrasing. Tan  &#124;   39  02:25, 30 November 2009 (UTC)
 * Thanks! It was just a thought that crossed my mind while reading it and it seemed uncontroversial. Hopefully it'll prove to be so. Dcoetzee 11:13, 30 November 2009 (UTC)

Derivative work?
File:SCPA Historical Marker.PNG? (being all pithy :)) If so, what to do? PUF? --Moonriddengirl (talk) 20:54, 1 December 2009 (UTC)
 * Hey. :-) That's almost certainly unfree. It's created by the state government of Ohio, which does not typically release its work into the public domain. It's in the US, where there is no freedom of panorama, so we're violating the copyright of the designer of the sign. Additionally, the text on the sign is legible and extensive, so we're violating the copyright of the writer (and this would probably apply even in a typical nation with FoP). I'd take it to PUF just because it's sufficiently complicated, but it seems like a sure delete to me. Dcoetzee 01:34, 2 December 2009 (UTC)
 * Thank you. I'll talk to the image uploader first, about potentially G7ing it. We're in communication about some pretty extensive text issues at the moment. --Moonriddengirl (talk) 14:41, 2 December 2009 (UTC)

Yes, another question
I'm trying to figure out PD status of some images that were published in a 1932 book. The initial conversation is at my talk page.

Brief story:
 * The book is an autobiography of Dane Christian Klengenberg, who died in 1931. It was published in London and Toronto in 1932 by Canadian editor Tom MacInnes, who died in 1951. It was also published in the US--unknown if it was within 30 days of original publication. Copyright was never renewed in the US. User:Jayvdb thinks there may be a good case for Canada as place of first publication, given the editor's nationality.


 * The book contains photographs of the subject. No photographer is identified for them.


 * As I understand it, if the book was first published in London and the photographer is unknown, it would be PD in the UK "70 years from end of year taken, or made available to the public if within 70 years of creation", according to, which would miss the 1996 cut off and (I believe) keep the photographs copyrighted in the US under the Uruguay Round Agreements Act. If the book was first published in Canada, I think, given that the photographer is unknown they would be PD either 50 years following publication or 75 years after the photograph was taken, whichever comes first (according to Commons), either of which would make them PD by January 1996.

Would photographs from an unknown photographer published in this book be accepted on Commons? --Moonriddengirl (talk) 14:41, 2 December 2009 (UTC)


 * May not need your input anymore. :) User:Physchim62 weighs in at my talk page with the rebuttable presumption of copyright in the author and also suggests simultaneous publication in UK and Canada, as well as copyright concerns with the Danes. Unless you disagree that the images are unusable, this one may be over. :) --Moonriddengirl (talk) 16:49, 2 December 2009 (UTC)


 * Hey - this is a somewhat difficult case. The relevant tags at Commons would be commons:Template:PD-UK-unknown, commons:Template:PD-Canada, and commons:Template:PD-US-not renewed. I think you can make a good case that all three of these apply in this case, but as you say, the URAA restored copyright in the US. The state of the URAA is an unsettled matter on Commons, see commons:Commons:Licensing. I'd say you could upload this (and tag with commons:Template:Not-PD-US-URAA) but I wouldn't recommend it unless you have some really compelling reason to. Dcoetzee 06:11, 3 December 2009 (UTC)
 * Thanks. I will pass that on. :) --Moonriddengirl (talk) 13:01, 3 December 2009 (UTC)

Commons image question
Hi, and Happy New Year. :) There's a question about an image on Commons at my userpage that you may be better able to address than I. Can you take a look at it and weigh in or take any action that seems necessary? --Moonriddengirl (talk) 17:06, 8 January 2010 (UTC)
 * Well, that one resolved swiftly already. :D So as not to have wasted your time in reading this altogether, might I ask you to take a look at File:Roundel of the Slovenian Air Force.png and File:Roundel of the Slovenian Air Force.svg and determine what if anything should be done with them? The uploader is certainly not the copyright holder, but I do not know Commons' stance on images of that kind. If they need to be retagged or other handled, can you help out? The contributor's other images are listed at Commons:Commons:Deletion requests/Images of Slovenian military-patriot. --Moonriddengirl (talk) 16:33, 9 January 2010 (UTC)
 * Hey, sorry for the slow response! I'll take a look at this now. :-) Dcoetzee 12:01, 12 January 2010 (UTC)
 * The image File:Roundel of the Slovenian Air Force.png is definitely a difficult case. It's unlikely of course that the uploader is the copyright holder (most likely the Slovenian Air Force itself is) but the image may be so simple as to fall under commons:Template:PD-ineligible. Alternatively, works of the Slovenian government may be public domain (I doubt it, but I can't find any information on Slovenian copyright law). There's no harm in nominating it, but it would likely be kept, if only on the PD-ineligible theory. Hope this helps, and hope you're well. :-) Dcoetzee 12:18, 12 January 2010 (UTC)
 * I'm doing fine, and glad to see you. :) I hope you're well also. I did not nominate it with the others because I thought it might be ineligible for copyright protection, but since images are not my main area thought to check with you. Given your response, I'll just leave it be. I've got plenty of others to work on. :D --Moonriddengirl (talk) 12:31, 12 January 2010 (UTC)

CCI image outstanding issue
Hi. Mer-C requests review of a couple of images at Contributor_copyright_investigations (the ones for Blackknight12). Can you take a look and weigh in there? I believe most if not all of them should be clear, but because of my previous interactions with the contributor would prefer somebody else evaluate them. --Moonriddengirl (talk) 14:36, 17 January 2010 (UTC)
 * Done. :-) You're right, I think they are all okay. Hope this helps. Dcoetzee 00:02, 21 January 2010 (UTC)

William Burton and Hollar
I've figured this one out, but it is tricky: see Talk:William Burton. I have just created William Burton (antiquary) but that is the one who the portrait is not of. I can create the correct other antiquary William Burton (antiquary d.1657) any time I see that it is not going to be an orphan. Charles Matthews (talk) 14:43, 5 February 2010 (UTC)
 * Great, thanks for helping sort this out! I certainly never would have guessed there were two antiquaries named William Burton who were contemporaries. Dcoetzee 02:50, 6 February 2010 (UTC)

NPG
So, what happened to that legal issue? Did they give up? Pcap ping  05:49, 19 February 2010 (UTC)
 * No new news as far as I know - WMF may have received direct correspondence from NPG, however. Dcoetzee 05:50, 19 February 2010 (UTC)

Region-based memory allocation
Hi, regarding Special:WhatLinksHere/Region-based_memory_allocation, can you please not create multiple redirects to an article that doesn't exist? Thanks. --Closedmouth (talk) 13:05, 24 February 2010 (UTC)
 * Er, I was in the process of writing that article at the time, which was a taxing process involving a lot of research, so it took a while. Maybe I should have created the redirects afterwards to avoid confusing anyone. Dcoetzee 13:16, 24 February 2010 (UTC)
 * Oops, look like I accidentally slightly changed the name of the final article and forgot to update the redirects. Sorry about that! Dcoetzee 13:17, 24 February 2010 (UTC)
 * Thanks. I'm aware that people like to create redirects to articles they haven't written yet, so I usually leave those for a couple of days, especially if there's more than one. So yeah. I've forgotten what my point was. Bye. --Closedmouth (talk) 13:45, 24 February 2010 (UTC)
 * Thanks for noticing this, I might have forgotten about checking those redirects otherwise. Dcoetzee 14:15, 24 February 2010 (UTC)

Math stuff
Hi. :) There's a math article at CP today, Mesor. I don't have the math background to assess the creativity there. Can you take a look? --Moonriddengirl (talk) 14:35, 17 March 2010 (UTC)
 * Cleaned it. :-) This is really more of a medical analysis thing, but the copyvio was pretty obvious (I'm particularly annoyed at the idea of copying references without reading them from a website that isn't even primarily about the topic of the article...). Dcoetzee 22:45, 17 March 2010 (UTC)

Updates to copyright instructions
Hi. Based on some feedback I've received, I've updated the instructions at WP:SCV and WP:CP. I've left a more indepth explanation at Wikipedia talk:Suspected copyright violations along with a request for feedback. As we try to get more people involved in this work, we want to be sure instructions are clear. Given your work, your input there would be very much appreciated. :) Moonriddengirl (talk) 13:49, 18 March 2010 (UTC)
 * Thank you for clarifying this. :-) It certainly was helpful to me to read. Hopefully it'll help others too. Dcoetzee 04:58, 19 March 2010 (UTC)

Connected Components
Hi Derrick. The definition of a connected component on the following page is incorrect: Connected_component_(graph_theory). It states: "In graph theory, a connected component of an undirected graph is a subgraph in which any two vertices are connected to each other by paths, and to which no more vertices or edges can be added while preserving its connectivity." However, "or edges" part of that sentence needs to be removed, as it is not true. Edges can be added to a connected component, while preserving its connectivity. See the NIST definition that you referred to:  which says: "such that no vertex of D can be added to S and it still be strongly connected". It does not say that edges cannot be added. Connected components of an undirected graph are not necessarily complete subgraphs; therefore edges can be added between nodes of the graph without threatening its status as a connected component. —Preceding unsigned comment added by 204.15.64.187 (talk) 21:02, 22 March 2010 (UTC)
 * You are both correct and also missing the point. Edges can be added to a graph which enlarge the edge set of some connected component. However, a connected component must partition the set of edges in the underlying graph - there cannot be any edge in the full graph which does not belong to a connected component of that graph. This is precisely what is implied by the statement that "no more edges can be added while preserving its connectivity." To consider a hypothetical example, a cycle graph may be divided into two "components" each containing half the cycle, and these two "components" together contain all vertices. They are not valid connected components because there are two edges in the underlying graph which are in neither component (in fact this graph has only one connected component).
 * Part of the confusion here may stem from the fact that the definition is not describing a partitioning of a graph into connected components, but rather defining a single connected component. In any case I've attempted to clarify the article. Dcoetzee 19:24, 24 March 2010 (UTC)

Image question at my talk page
Hi, Derrick. There's an image question at my talk page dealing with possibly copyright expired UK images and the impact on them of the URAA and CTEA. There seems to be some divergence between policy and practice (well, guideline, but I couldn't resist the alliteration) here, and I wanted to check with you to see if you can help answer the question. It's here. I'd be most grateful. :D --Moonriddengirl (talk) 17:24, 7 April 2010 (UTC)

Pestering you, as always
Hi. :D We're trying to figure out how non-admins can note that a CCI is ready to close. Can you determine if the last suggestion at Wikipedia talk:Contributor copyright investigations is plausible? It's been sitting since the 7th, but nobody who knows 'bout such things has happened by. --Moonriddengirl (talk) 19:37, 13 April 2010 (UTC)


 * Could I also draw your attention to Wikipedia talk:Contributor copyright investigations, which seems to have your name on it. Thanks. --Tagishsimon (talk) 16:44, 10 May 2010 (UTC)

You don't get to close afds early. Snow keep is not a policy, and AFD is not a vote. DRV coming your way.- Wolfkeeper 03:43, 2 June 2010 (UTC)
 * Suit yourself. Dcoetzee 16:10, 2 June 2010 (UTC)
 * I would not have phrased it as adversarially as Wolfkeeper, but I agree that WP:SNOW was not applicable in this case. Would you consider reopening the AfD so that we don't have to go through DRV?  Powers T 13:21, 3 June 2010 (UTC)

Commons image?
Hi, Derrick. It's been forever since I've run into you. I keep an eye out, but evidently my timing has been bad. :) In any event, when I got a question about a Commons image on my talk page, it seemed a perfect excuse to drop by and say hi in context of asking your feedback. :D Could you take a look at User talk:Moonriddengirl? The uploader of File:6 commando adour raid 1942.jpg is now concerned that he may have inadvertently licensed it incorrectly, and he is most anxious to do the right thing. Hi! --Moonriddengirl (talk) 17:51, 23 June 2010 (UTC)
 * And since I'm already bothering you, um, what? (No, I mean, what? Really, what?) Does any of that make sense? --Moonriddengirl (talk) 21:34, 23 June 2010 (UTC)
 * Hey, good to hear from you. :-) All of those edits have been reverted. In the first edit, they claimed that they solved a long-standing open problems in computer science and that the source code they're pasting is the solution (in actuality it's not even remotely relevant). In the second edit they pasted a bunch of... what appear to be menu specifications into the general article on codes (which is completely unrelated). In the third they posted the same code as in the first one to a different article - it's still meaningless and irrelevant. They appear to be some crazy troll. :-) Dcoetzee
 * Thank you. :) When I saw that similar edits had been permitted to stand for a day, I wasn't sure if it was because they weren't noticed or because there was something to them. It didn't look constructive to me, but.... Well, what do I know? :) If it says its related to computers, that is. And thanks for your feedback at my talk page question, too. :D --Moonriddengirl (talk) 10:46, 24 June 2010 (UTC)

Request
Hi, Derrick. I know you're a busy fellow, but I'm wondering if you would mind watchlisting User:Pohick2. He is currently indefinitely blocked for copyright infringements (see ANI thread). He has yet to indicate even a desire to be unblocked, but since he may (he has certainly been a dedicated contributor) it would be good to have an experienced copyright admin who can work with him. There have been several conversations with him in the past, but the most extensive I've had is at User talk:Pohick2/Archive/ and subsequent, in case you're wondering what ground has already been covered. I think that having a fresh person to talk to might be beneficial should he decide to consider resuming his account. Our last conversation, I'm afraid, didn't end well. :/ --Moonriddengirl (talk) 01:49, 10 July 2010 (UTC)
 * Done :-) Dcoetzee 07:45, 10 July 2010 (UTC)

Context
Hello. Please look at this edit. I don't think the phrase "In real analysis,..." has the effect of telling the lay reader that mathematics is what the article is about. Michael Hardy (talk) 03:38, 16 July 2010 (UTC)
 * Okay. Dcoetzee 05:27, 16 July 2010 (UTC)

Image origin
Hi. A recently blocked contributor, User:Wiki id2, acknowledged that all of the images he had uploaded under claim of his own authorship were not actually his, except one. Since that one (File:Taha Hussain.PNG) was a clear crop, I suggested he upload the complete picture to help prove that he was the photographer. He has now uploaded File:Taha Hussain.jpg, and requests that we delete it once we are satisfied. Since images are way more your thing, would you mind taking a look? Should that alleviate my concerns about that image? It doesn't have metadata, but looks plausible. Your input would be appreciated. :) --Moonriddengirl (talk) 17:08, 20 July 2010 (UTC)
 * Hey :-) Based on contributions, I have every reason to suspect that Wiki id2 is a Pakistani person in the same age range as Taha Hussain, so may very well have been in a position to take a photograph of him (he's also himself responsible for the article). The resolution is unusual (it's probably a downscale of the original using some kind of standard photo editing tool, as no real camera would produce an image with this resolution), but it seems legit to me. Dcoetzee 20:05, 20 July 2010 (UTC)
 * Thank you kindly. :) I will not pursue this one further, then, but will regard it as plausible based on this and based on his coming clean, eventually, about the other content. --Moonriddengirl (talk) 19:22, 20 July 2010 (UTC)

You need a separate talk page just for my requests
Hi, Derrick.

Adopt-a-user reminder
Hello, I have completed a general cleanup of the adopter information page for the adopt-a-user project, located here. During my cleanup, I have removed several inactive and retired users. In order to provide interested adoptees with an easy location to find adopters, it is essential that the page be up-to-date with the latest information possible. Thus:


 * If you are no longer interested in being an adopter, please remove yourself from the list.
 * If you are still interested, please check the list to see if any information needs to be updated or added - especially your availability. Thank you.


 * You are receiving this message because you are listed as an adopter here.

Repeated links proposal
This is a proposal to change the Repeated links section of the MOS. Please edit &/or comment on the talk page as you see fit.

Feel free to move the proposal/discussion straight to the Wikipedia talk:Manual of Style (linking) if you wish. I just thought we might establish some sort of consensus first, out of the heat and fury over there. --Michael C. Price talk 10:20, 28 September 2010 (UTC)

When making changes to scientific articles you have to understand the subject
You rearranged sections in arithmetic coding. Do you understand that first part is not clear for anyone who try to become familiar with the subject. It does not matter if it is right or wrong, it does not explain anything. The explanation that arithmetic coding narrows interval on every step is right or meaningless. People need to understand where compression comes from. Why narrowing down interval leads to shorter message? Why this shorter message is shortest possible? And how to restore message back from final interval? Besides that, first section does not mention that compression occur by choosing shortest fraction from final interval and not from narrowing down the interval itself. I wrote that sections that you moved down. I actually don't care if you remove them or not because I explained everything on my web site, which shown by Google on the first page even before wiki. Did you write your own arithmetic coder ever? I wrote several coders in open source that are used by people. If you want to arithmetic coding via narrowing interval starting from [0,1) that is fine, but explain how to encode, decode, explain why it is numerically stable and converge and what is the limit to which it converges. It takes two pages of printed text to explain this and reader needs to know high school math to understand it but it requires high level on understanding to be able to explain it. C-processor (talk) 08:25, 3 October 2010 (UTC)

If it is your explanation on the top part of arithmetic coding section I can tell you that even Claude Shannon would not understand it in 1948 if he read it. It may be correct but useless. You know the joke how two guys got lost at see on the boat and met another boat with fisherman. They asked "where are we" and got the answer "you are in the boat". They decided that fisherman was mathematician because the answer was precise but useless, so this is upper part of the article. You can make the whole article useless by removing my section and will have more readers on my site. —Preceding unsigned comment added by C-processor (talk • contribs) 08:45, 3 October 2010 (UTC)
 * I've written many arithmetic coders, as a matter of fact. I appreciate your contributions and the interesting connections they raise but I feel like the new text assumes a lot of background that readers unfamiliar with the subject would not have - just as with basic arithmetic, it's important to understand the basic algorithm and how it is performed before understanding its theoretical basis. This is the value of the introductory examples. Placing this first also allows the remaining content to discuss the theory without expounding upon detailed examples of its own. Additionally, I feel like the examples are more accessible than the theory, and I prefer to present articles in roughly an order of increasing difficulty. It does depend on what audience you're going for though, and maybe it would be better to intermix the algorithm description with the theory somehow. Dcoetzee 07:39, 4 October 2010 (UTC)

Continuous-repayment mortgage
Hmm - the diagram you minimised in Continuous-repayment_mortgage is fairly important in respect of illustrating the characteristic curve of a CRM. But having the diagram and all relevant text viewable at the same time does enhance readability. And of course readers can always click to enlarge the thumbnail.

Any further comments/suggestions you may have would be appreciated - I am trying to deal with another editor's comment about the article being too technical for most readers. Actually IMHO it is not - it is not beyond the level of first year university Maths and there are far more mathematically challenging articles elsewhere on Wikipedia. All the same I'm sure the article would benefit from a rigorous mathematical critique.

Neil Parker (talk) 16:23, 5 October 2010 (UTC)
 * You can feel free to enlarge it by adjusting the size (200px -> 300px or whatever) but the use of frame is discouraged, since it prevents the image from being replaced by a higher-resolution or vector version for print editions. I think the article is okay, but many people who would like to understand this particular topic don't have a first-year university background, so I think it could use a high school level introduction similar to compound interest that discusses in detail how the relevant limit is achieved. Dcoetzee 23:04, 5 October 2010 (UTC)

The CRM balance function can be obtained either by:

1) Using limit theory - see Continuous-repayment_mortgage.

2) Integration of cash flow elements. Briefly mentioned in the introduction

3) Solution of differential equation

I would have thought the first mentioned does more or less what you suggest above. The only slightly advanced concept (ie possibly beyond high school level) mentioned here is the very same limit that is used in determination of the formula for continuous compounding. Perhaps what is needed is an online reference to a derivation of that limit similar to the one given in "Algebra and Trigonometry" (Munem and Foulis) which I have specifically included as an inline reference. Thanks for the feedback all the same.

Copyright issue?
Hi. There are two listed copyright issues at CP today that could use somebody familiar with computers: High-bandwidth Digital Content Protection and AACS encryption key controversy. I, of course, don't even know what a cryptographic key is. :) Is this something you can handle, or should I try to dig up assistance at VPP or something? --Moonriddengirl (talk) 18:57, 5 October 2010 (UTC)
 * Hey, I responded at WP:CP. The gist of it is that it's not a copyright issue, because cryptographic keys are too short to be eligible for copyright protection (for example, the AACS key is 32 characters of text). Any issues with publishing them would fall under the DMCA, not copyright law. Dcoetzee 00:11, 6 October 2010 (UTC)

An update from adopt a user
Hi there ! You may be wondering, what have I done to sound the alarm this time? Nothing. I'm messaging you in regards to the adopt-a-user program, which currently has a backlog of users wishing to be adopted. This doesn't make much sense, as we have a considerable list of users offer adoption, so there shouldn't be any backlog. I've begun to eliminate this backlog myself through a matching program, but I need your help to make it work. Of course, adoptees and adopters don't have to go through there, but I believe it helps eliminate the backlog because someone is actively matching pairs.

On the list of adopters, I have modified the middle column to say "Interests." It's easier working with other users that have similar interests, so if it's not too much to ask, could you add your interests in the middle column? For example, if I was interested in hurricanes, computers, business, and ... reptiles? I would place those in the middle column. Counter-vandalism and the like can also be included (maintenance should be used as the general term). The more interests, the better, since adoptees can learn more about you and choose the one they feel most comfortable working with. The information about when you're most active and other stuff can go into the "Notes" section to the right.

Finally, I've gone around and asked adoptees (and will in the future) to fill in a short survey so adopters can take the initiative and contact users they feel comfortable working with. We all know that most adoptees just place the adopt me template on their user page and leave it - so it's up to us to approach them and offer adoption. So, please take a look at the survey, adopt those that fit your interests, and maybe watchlist it so you can see the interests of adoptees and adopt one that fits your interests in the future.

Once again, thank you for participating in the adopt-a-user program! If you wish to respond to this post, please message me on my talk page.

Pronunciation request
The Pronunciation task force has you listed as a member. Would you be able to make a recording for Albany, New York?  upstate NYer  01:10, 18 October 2010 (UTC)

Question about table copyright
Hi. There's a question at my user talk page with which I could use some assistance. It relates to whether or not some tables created by the user (who asked) would infringe on some figures used in an article. They correspond point per point, but I'm unsure how creative they would be judged to be. Can you take a look at User talk:Moonriddengirl and offer some feedback? I've identified which figure corresponds to which table to hopefully make this less of a chore. :) I'd be gratful. --Moonriddengirl (talk) 13:08, 28 October 2010 (UTC)

File:FIT spotter card.jpg
Hi Derrick, thanks for your comments about this file, I've changed it to being fair use, and the resolution has been lowered, do you think you could take a look at the FUR and let me know if it is ok? Thanks a lot. SmartSE (talk) 12:35, 6 November 2010 (UTC)
 * Looks good to me - the only unclear point is that a portion would not suffice (e.g. I could imagine maybe half of it would illustrate the point) but I think it's fine like it is. It doesn't have to be as low res as you made it, only low enough that it's not good for printing - unless you shrunk it for privacy reasons. Dcoetzee 01:22, 10 November 2010 (UTC)

Hi, Derrick. This file was inadvertently deleted in 2007 as duplicated on Commons, but the original was not attributed. (See ) Since the image on Commons does not have any kind of image source box that I recognize, I'm not sure where to log the attribution. Can you give some input or help out?

Help, o computer person!
Hi. I don't know if you have time or interest in this one, but Responsiveness came up at CP today. It had a few sentences copied from its source. Looking at it, though, I'm thinking that it may be a serious issue of synthesis. I was trying to replace it with sourced comment, but if I do that, I'm just going to wind up with a WP:DICDEF. Can you do something with that? Could anybody? --Moonriddengirl (talk) 16:13, 17 November 2010 (UTC)
 * Hey, took a look at this. I've heard the term responsiveness and I have heard it applied to both process scheduling (as discussed in Responsiveness vs Performance) and to user interfaces (as discussed in Delays). The article requires improvement e.g. I find it a bit too specific and constrained ("The three steps are", "The other three [criteria] are"), and it does represent a combination of concepts from different subfields, but I think they're closely-related enough that it's an acceptable topic for an article. Dcoetzee 01:09, 18 November 2010 (UTC)
 * Okay. That's all alien to me, but if the article seems valid to you, I'll trust that it is. :) --Moonriddengirl (talk) 01:15, 18 November 2010 (UTC)

Contribution team
Greetings! Please excuse this intrusion on your talk page, and allow me to invite you to participate in the newly-formed Wikipedia Contribution Team (WP:CONTRIB for short)! The goal of the team is to attract more and better contributions to the English Wikipedia, as well as to help support the fundraising team in our financial and editing contribution goals. We have lots of stuff to work on, from minor and major page building, to WikiProject outreach, article improvement, donor relations, and more—in fact, part of our mission is to empower team members to make their own projects to support our mission. Some of our projects only take a few minutes to work on, while others can be large, multi-person tasks—whatever your interest level, we're glad to have you.

If this sounds interesting, please visit WP:CONTRIB and sign onto the team. Even if there does not appear to be anything that really speaks out as being work you'd like to do, I'd encourage you to join and follow the project anyway, as the type of work we'll be doing will certainly evolve and change over time. If you have any questions, please don't hesitate to contact me, or ask on the team talk page. Regards, &rArr;   Dan Rosenthal    Wikipedia Contribution Team  22:20, 18 November 2010 (UTC)

Google Art Project, extracting images
Hello Derrick, let me introduce myself, I am David, a student of Art History in Portugal. We (at my university) are planning to create a project that would store high-quality images of paintings, books and other works of art in digital format. The goal would not only be to store human art/culture for preservation, but also to make it available online. That "digital library" would then be available to anyone, in particular students, to facilitate analysis of the works. This is where we would like to request your help, you see, at first we plan to collect material already in digital form, and we are planning to use Google Art Project as one of the initial sources, the problem is that we can't really get decent pictures from there... I noticed you uploaded some paintings from there into wikipedia, so I was wondering if you could provide us with the tools or knowledge you used, if you are OK to share that... Hope you can help. Cheers, David Salvador. —Preceding unsigned comment added by 2.80.234.247 (talk) 20:19, 27 February 2011 (UTC)
 * Hi David, all public domain works from the Google Art Project are available on Wikimedia Commons at commons:Category:Google Art Project at full resolution, except the gigapixel images which are at reduced resolution (I plan on making those available at full resolution at another site, since they require special tools to process). It is a simple matter to download all images from a Commons category automatically using the Mediawiki API (let me know if you need help with this). I cannot of course redistribute the non-free copyrighted images (nor could your site do so without a license). Commons is also home to many other high-quality images of public domain artwork, perhaps hundreds of thousands, and will be a good source in general for your project - commons:Category:PD Art is a good starting point to explore.

Quicksort partition example image
Hi! I've recently made an edit simplifying the inplace version of the quicksort algorithm. It basically always uses the last element as the partitioning pivot.
