Question at[edit]

Wikipedia:Files_for_deletion/2012_September_2#File:Into_The_Vietnamese_Kitchen_p10.jpg .Thanks In ictu oculi (talk) 03:26, 3 September 2012 (UTC)

I've replied there. —Bkell (talk) 03:39, 3 September 2012 (UTC)

Is there a tool for that?[edit]

This was very helpful, and I wonder how you figured it out. I've done this by looking at the "prev" diffs that pop up on mouseover in the page history, or use the radio buttons to do diffs for blocks of time to narrow it down, but I can imagine a tool might exist to make this easier - that attempts to determine the diff and editor associated with content on the page. Do you use such a tool? -- Scray (talk) 11:42, 3 September 2012 (UTC)

I wish I knew of such a tool. I just opened the history of the page and manually did a binary search on the previous versions, seeking the edit at which the word "soundiferancic" first appeared. It's like the game where someone thinks of a number and you try to guess it, and after each of your guesses you are told "too high" or "too low." So, for example, I looked at the last edit from 2011, which did not contain the word, so I knew it had been inserted this year; then I looked at the first edit from May; then I looked at an edit from 14 June; and so on.
If you're tracking down vandalism in this way, it helps to realize that you can ignore edits which were immediately reverted, because they don't change anything. Also, a lot of vandalism is done by anonymous editors, so when you get close you can start focusing on the anonymous edits. Even so, it's a bit of a tedious process. —Bkell (talk) 15:44, 3 September 2012 (UTC)
Yes, seems we approach this in just the same (tedious) way - the binary search method is the right term for what I was referring to when I mentioned use of the radio buttons. Years ago I saw editors refer to a (defunct) tool called "who wrote that" or somesuch. Certainly, such a tool could not be perfect, but in many cases it should be tractable. Once I find that person, searching their contributions around the same time sometimes yields strange vandalism sprees. -- Scray (talk) 16:11, 3 September 2012 (UTC)
Just ran across the blamer tool, which seems like it could be quite useful. Cheers! -- Scray (talk) 05:33, 19 September 2012 (UTC)

Johnny Torrio Image[edit]

If the image I uploaded has to be deleted, then so be it. I will not lodge any protests. Thanks for letting me know. And003 (talk) 21:44, 4 September 2012 (UTC)

Harmonic Maths[edit]

I forwarded the permission from the author. Pkeets (talk) 19:27, 30 September 2012 (UTC)

Okay. I've added {{OTRS pending}} to the file description page. —Bkell (talk) 19:38, 30 September 2012 (UTC)

Pegrema photo[edit]

Hi Bkell! You have left me a message at my Talk page stating that the file [File:Karelija Pegrema.jpg] I uploaded a while ago lacks a copyright verification. Unfortunately it looks like since the file was uploaded, the site where I took it from (http://www.nordfoto.ru/) ceased to exist. Therefore, I'm not sure how to verify the license tag. Thank you. Khakhalin (talk) 21:26, 30 September 2012 (UTC)

Right, I saw that too. I checked the Internet Archive at http://www.archive.org/ before I left the message on your talk page. I found an archived copy of their photo gallery of Medvezhyegorsky District, Медвежьегорский район, but unfortunately there is no archived copy of the subgallery for Pegrema (Деревня Пегрема) where I imagine you found the photo you uploaded as File:Karelija Pegrema.jpg. In any case, at the bottom of the galleries that are archived, there is a copyright notice that says "Copyright © 2002, Валерий Гуляев", but I do not see any mention of the GFDL. So I don't see any evidence to support the {{GFDL}} tag that is currently on the File:Karelija Pegrema.jpg file description page. —Bkell (talk) 00:24, 1 October 2012 (UTC)

So God Made a Farmer[edit]

I understand your point on the "speech became famous" comment. I was mostly basing it on the Atlantic comment "Here's the text of his speech, made newly famous during the Super Bowl". Is there a way you think that information can be incorporated? Ryan Vesey 13:45, 4 February 2013 (UTC)

The statement that the speech is now famous is an opinion at this point, not a fact. I suppose you could say something like, "The speech has been described as 'newly famous,'" with a reference to the Atlantic, which is a verifiable fact; but that statement doesn't really convey any meaningful data (and how does the Atlantic know it's now famous, anyway, and not just a flash in the pan?). I think you should leave this claim out of the article. See Wikipedia:Let the dust settle#Notability requires more than 15 minutes of fame. The word "famous" is an example of a class of words commonly called "peacock terms" on Wikipedia; such words "make unprovable proclamations about a subject's importance" and should be avoided. See also WP:ASF. —Bkell (talk) 14:17, 4 February 2013 (UTC)

Good call[edit]

File:Windows Setup.jpg[edit]

Hi.

I hope I am not bothering you, but I thought it is important to drop you a note about your edit in File:Windows Setup.jpg. I think it is good thing that the image isn't PNG. JPEG screenshots are smaller and the lost fidelity (due to artifacts) is actually a plus for WP:NFCC#3b compliance.

Best regards,
Codename Lisa (talk) 22:21, 7 March 2013 (UTC)

Hmm. It is not generally true that JPEG screenshots have a smaller file size; PNG files are usually smaller for images that have large blocks of solid colors, which includes most screenshots of computer programs. However, a JPEG might be smaller in this case because of the gradients around the edges.
I do not interpret WP:NFCC#3b as promoting a loss of fidelity in images via means such as blurring, garbling, or introducing compression artifacts. Instead, I think it refers to using low-resolution images and low-fidelity sound samples. I have always thought that, within the low-resolution requirement for images, we should have the most accurate representation of the image that we can get. —Bkell (talk) 22:32, 7 March 2013 (UTC)
Hello again. I see that I may have been wrong about my interpretation of "fidelity". I now remember that "fidelity" is used as a counterpart of "resolution" in audio, since "resolution" has its own meaning in that domain. (My way of thinking might have been in part influenced by FleetCommand's practice of reducing image color depth and putting distinction between "resolution" and "dimension".) Since you have a valid counterargument, I cede my position. But would you say that in general, I should avoid JPEG screenshots in favor PNG whenever possible? Best regards, Codename Lisa (talk) 00:08, 8 March 2013 (UTC)
Well, it depends on the content of the screenshot. If it's a screenshot of a video game, for example, so that the image is essentially photographic in its nature, then a JPEG might be best; the JPEG format was designed to work well with photographs. On the other hand, if it's a screenshot of a typical window with text, large areas of flat color, and sharp edges, then a PNG is usually a better choice than a JPEG. —Bkell (talk) 00:12, 8 March 2013 (UTC)

Mathematical coincidence & Almost integer[edit]

removed a bunch of random stuff that had neither references nor connections to things in other Wikipedia articles


Well... I'm glad you did. It feels really refreshing and motivating to have someone pissing all over your work...

Anyway... you said that the "random stuff" in question had "no connections to things in other Wikipedia articles": this isn't exactly true: a few of the approximations -or coincidences- that you chose to remove were based on (or related to) other similar or equivalent relations from the related article almost integer. These are:

  • 2 \pi + e \approx 9
  • \pi^2 - \frac{e}{\pi} \approx 9
  • \pi^9 - e^8 - \pi \approx 26825e \approx \pi\sqrt[8]{\pi\over10}
  • 2\ \ln^3\pi \approx 3\pi \approx e^{\sqrt[3]{3\over2}}

Also, the fact -or coincidence- that the value of the Euler-Mascheroni constant \gamma is so close to the value of 1\over\sqrt3 is explained by applying the Gaussian quadrature for 2 points to the integral definition of the constant. So perhaps next time it would be better to check your facts first before taking such rash and swift decisions. And here's another outrageous idea: how about actually trying to contribute yourself with links, references, and connections, instead of simply hacking away the information ? P.S.: I've sometimes felt a bit guilty for not contributing (financially) to Wikipedia... thanks for clearing my conscience once and for all. — 79.113.230.39 (talk) 05:46, 9 March 2013 (UTC)

I'm sorry I upset you. What I am trying to avoid is an article that is just a miscellaneous collection of facts that editors happen to discover and find interesting. The mathematical coincidence article was really bad about four years ago—hardly any of the things listed in the article had references to justify their inclusion in the article as notable coincidences that have been observed and covered by reliable sources outside Wikipedia. Since then it has gotten a lot better, but we need to make sure we include references to reliable sources to demonstrate that the facts in the article are not original research.
Frankly, the almost integer article is awful. It's just a huge unreadable mess of random trivia, with no citations to outside references that show that the facts are anything other than interesting discoveries made by Wikipedia editors. That is not what a good Wikipedia article should be. Wikipedia is not an indiscriminate collection of information. The mathematical coincidence article looked a lot like that in 2009, but it has improved a lot. How did that improvement come about? Part of the improvement was made by finding references for various claims, and part of the improvement was made by deleting claims for which no meaningful references could be found.
You seem to believe that deletion is not contribution. I respectfully disagree. Wikipedia articles need a certain amount of pruning as they develop.
Now, let's see if we can come to a satisfactory solution about the items I removed from the mathematical coincidence article earlier. Can you find reliable sources that discuss those particular coincidences? If so, I fully support their inclusion in the article, with references to those sources. —Bkell (talk) 06:42, 9 March 2013 (UTC)
The properties of \phi, Heegner numbers, and Ramanujan's constant are neither random, nor the discoveries of Wikipedia editors. There is a mathematical reason or explanation for them. The property of Gelfond's constant is random, however, it is not the the discovery of Wikipedia editors. And the square root of 10 and cube root of 31 have been historic approximations for \pi, albeit perhaps less famous than others. Then again, these entries are not the ones you've deleted, so perhaps you already knew all this. And I never said that deleting meaningless junk is not an acceptable way of contributing to Wikipedia... I just thought that these particular entries did not necessarily belong into that category. — 79.113.196.61 (talk) 07:27, 10 March 2013 (UTC)
Okay. Let's suppose, just for the sake of discussion, that I don't believe you when you claim that the properties of these various numbers are not the discoveries of Wikipedia editors. Can you prove to me, by providing references to external sources, that these things have been discussed in a scholarly context outside of Wikipedia? —Bkell (talk) 21:46, 10 March 2013 (UTC)
Theoretically, yes. Practically, no. I personally don't have the (re)sources to do that. Not unless one considers my memory a (re)source. :-) — 79.113.227.82 (talk) 11:24, 12 March 2013 (UTC)

Proportions question on math ref desk[edit]

Thank you so much for a perfect answer to my question about why the pencil measure trick works when setting up proportions. Manytexts (talk) 08:13, 9 March 2013 (UTC)

You're welcome! —Bkell (talk) 08:26, 9 March 2013 (UTC)

Ping....[edit]

Hi Bkell, I left you a response here. All the best -- CassiantoTalk 21:19, 13 March 2013 (UTC)

log n and lg n are not same thing[edit]

I think lg n and log n are not same thing. For the former base is 2 but for the later base is 10. This is in context of Binary Search Tree. — Preceding unsigned comment added by 199.67.140.45 (talk) 12:58, 22 March 2013 (UTC)

True, but O(log n) and O(lg n) are the same thing, because log n and lg n differ by only a constant factor (by the change-of-base formula for logarithms). —Bkell (talk) 15:46, 22 March 2013 (UTC)


Also, 199, beware of assuming that unadorned "log" always means base 10. In mathematical writing, it will ordinarily mean the natural log (base e). Yes, "ln" exists, but not everyone uses it. --Trovatore (talk) 17:10, 22 March 2013 (UTC)
