Visual comparison of convolution, cross-correlation and autocorrelation.[edit]

Hello Cmglee. You seem to have done a lot of work for the world, it's great. I might be wrong however I think I have found an error in your illustration in 'Visual comparison of convolution, cross-correlation and autocorrelation.'.

Based on the definition of cross-correlation in :

(f \star g)[n]\ \stackrel{\mathrm{def}}{=} \sum_{m=-\infty}^{\infty} f^*[m]\ g[m+n].

f is filter and g is the signal which the filter f is applied. As cross-correlation is not commutative (unlike convolution), this interpretation can not be inverted. Therefore I think the symbol f and g in your illustration must be switched. Ttlxjdycj (talk) 13:28, 12 February 2014 (UTC)

Please see File_talk:Comparison_convolution_correlation.svg. Cheers, cmɢʟeeτaʟκ 02:05, 19 September 2014 (UTC)


Fixed Apollo 11 date and added chronological order.

Hello Cmglee. Great image, but there's a typo to do with Apollo 11 landing date. It landed on 20 July 1969 (not 24th). I noticed due to looking up information about today's news of the death of Neil Armstrong. Bryandongray (talk) 23:41, 25 August 2012 (UTC)

Well-spotted, and thanks for bringing it to my attention, Bryandongray. I've fixed the typo and added numbers to indicate chronological order, as on the right. cmɢʟee 20:05, 27 August 2012 (UTC)

Use of a Photo[edit]

Hi Cmglee. I am a freelance photo researcher working on a video for Travel and Leisure magazine about all the new attractions this summer (2012) in London. I would like to use your Wikimedia Commons photo of the outside of the Olympic Aquatics Centre for a short 1-2 second use in this upcoming Travel and Leisure video "London's Coolest Attractions". I will credit you as the author of this photo/Wikimedia Commons. Can you let me know if you have any issue or problems with this use? I can be reached at, thank you so much for posting this image in Wikimedia Commons. (GillenEdits (talk) 17:28, 12 July 2012 (UTC)) (UTC)

Hi Paula/GillenEdits. Sure, I'd be glad to contribute the photo under Wikimedia Commons' terms. Would you be able to post a link to your finished work here, please? cmɢʟee 17:47, 12 July 2012 (UTC)

Template:Dont overwrite (The above was a template, following is by a human.) Sorry to throw this template at you, you did upload a useful impovement at File:Fukushima I NPP 1975 medium crop.jpg, the only problem is the rotation lost all the image notes and changed the appearance of the thumbnails for existing users. I have moved your version to File:Fukushima I NPP 1975 medium crop rotated labeled.jpg so you may ignore the last part of the template above. -84user (talk) 00:25, 16 March 2011 (UTC)

March 2011[edit]

Thank you for your contributions. Please remember to mark your edits, such as your recent edits to Solar System, as "minor" only if they truly are minor edits. In accordance with Help:Minor edit, a minor edit is one that the editor believes requires no review and could never be the subject of a dispute. Minor edits consist of things such as typographical corrections, formatting changes, or rearrangement of text without modification of content. Additionally, the reversion of clear-cut vandalism and test edits may be labeled "minor". Thank you. In addition to not being a MINOR edit, I'm questioning the wisdom of changing formats from JPG to SVG, considering compatibility. — UncleBubba T @ C ) 02:37, 16 March 2011 (UTC)

Hi UncleBubba,
Thanks for your note. My bad for marking it minor; I thought minor is for when no text is changed. Re:
> In addition to not being a MINOR edit, I'm questioning the wisdom of changing formats from JPG to SVG, considering compatibility
I found the labels in the original JPEG too small to view in thumbnail mode though there is plenty of space available.
I've ensured that it renders well on the MediaWiki renderer and several modern browsers. Regardless, most Wikipedia readers will see the automatically rendered JPEG instead of the original unless they choose to view it.
Moreover, shows that it has been translated to several languages. My initiative lets editors easily translate it into their language without needing to fix the background.

Template:Distance from Sun using EasyTimeline[edit]

Hi. I recently came across this template and noticed that Mercury and Eris lead to disambiguation pages. However, try as I might, I could not edit the template successfully so as to disambiguate the links. Perhaps you will better know how to manipulate EasyTimeline to achieve this? It Is Me Here t / c 16:28, 28 April 2011 (UTC)

Hi It Is Me Here. Thanks for pointing it out and trying to fix the links. I've fixed the links using [[Mercury_(planet)|Mercury]] and [[Eris_(dwarf_planet)|Eris]] as EasyTimeline seems to fail on spaces in links.

File: Thin_lens_images.svg[edit]


Hello Cmglee,

I believe this image is incorrect:

The letters on the right side should only be inverted vertically, not horizontally. I could do the calculations, but one way to see it is that if the letters were flipped horizontally it would imply that light from the back of the letter reaches your eye first, which is not the case.

Otherwise, the image is very useful. Keep up the good work!

Well-spotted and thanks, DaedalusInfinity. I've fixed the SVG. Let me know if you find any other errors. cmɢʟeeτaʟκ 12:26, 9 August 2011 (UTC)

Thanks for the SVG fix![edit]

I noticed your edit on the SVG source of this file, and I was really impressed. I could tell from your user page that you extensively create/modify pictures on Wikipedia, including vector graphics. Glad that you improved mine this time, truly appreciate it.

If you don't mind, could you help me with the other 3 SVG graphics? I'm referring to this, this and this. All those graphics were made manually, meaning I was arranging those hexagons, naming them and trimming coordinates in the source, so that file sizes were kept small. I believe there is a way to create this sort of diagrams less painstakingly, just that I haven't come across it.

Could you advise me on representing by-elections clearly in the diagrams? Should texts be added for that matter? Also, what do you think about these pictures being transferred to Commons, with additional 2 sets of translated versions, in Bahasa Melayu and Chinese? Hytar (talk) 08:56, 17 August 2011 (UTC)

Demonstration of suggestions
Thanks for the kind words, Hytar; I try my best :)
I would find labels for the by-elections useful, but do get a second opinion. I prefer multiple layers of information in a single diagram but some Wikipedians find mine too cluttered.
I normally upload my images to Commons, though they have stricter policies e.g. on the corporate logos you've made.
I've done similar changes to the 3 images you linked. I must say I really like your idea of using hexagons for equal-area representation and also using more saturated colours with a border to show changes.
Did you use a script or program to generate the SVG? If not, kudos on your great effort! Here are some suggestions to reduce the work:
  1. Write a script. I use Perl to generate mine.
  2. Use defs blocks and xlink:href to make each hexagon a separate unit which you can place using the transform attribute.
  3. "Cheat" by approximating hexagons with squares with corners cut off, so their coordinates are much simpler.
These techniques are in used in this SVG image.
Let me know if you'd like to collaborate on any new SVG visualisations you have in mind.
cmɢʟeeτaʟκ 12:53, 17 August 2011 (UTC)

>== Re: SVG Check ==

Yes, all sound like good suggestions.

Unfortunately I'm very busy at the moment for various reasons. This means I've worked up a large backlog of "features I'd like to implement" :( (In fairness, this is also because I get new bugs in my inbox most days, and I devote time to fixing them as soon as I know about them.)

If you file a JIRA feature request, then at least your good suggestions won't get lost, even if it takes me a while to get round to doing anything about them (I do apologise for this, I just try to be realistic about these things). To do so, you have to register first (your Wikipedia login details won't "just work" unfortunately), then the "New feature request" button is fairly obvious.

Hello, can I ask you to please undo some of the changes in this edit? It looks like it was a revert of my revert (without explanation), and per WP:BRD, these should be discussed before being repeated. The colour coding is fantastic, but you've changed the column titles and repeated alot of changes that I reverted. Also, why have you removed diacritics from names (even in quotations)? This pushes the reader through redirects...

...Although I've just noticed that I've put "Supportiveive" instead of the "supportive" that was agreed upon on the talk page (a mistake). Thanks, Nightw 14:04, 1 November 2011 (UTC)

Thanks mate. Appreciate it. Nightw 21:11, 1 November 2011 (UTC)
That's quick; I was going to reply after fixing the page. Sorry about the mess-up, Nightw. I didn't realise my text editor corrupts non-ANSI characters and your changes were lost due to the merge conflict.
I've tried to restore the section to the state before I edited it, except the following:
  1. Colour-coding, giving more width to the Further Details column, and removing unused style attributes (my original intentions)
  2. Restoring the headings -- I think "Position" and especially "Rec." are not descriptive enough
  3. Restoring "Support" and "Oppose" -- I think "Supportive" and "Against" are unnecessarily long
  4. Restoring a reference for Bosnia-Herzegovina removed without explanation
Hope that's ok now! cmɢʟee'τaʟκ'maιʟ 21:24, 1 November 2011 (UTC)
After reading the discussion on the Talk page, I've changed Support/Supporting to Supportive and Oppose to Against. cmɢʟee'τaʟκ'maιʟ 21:35, 1 November 2011 (UTC)
Yeah, looks good. Thanks for taking the time to review. And thanks for editing the table as I consider it an improvement. Regarding the headings, I think a key will probably be added to better explain the table (will do so myself as soon as I get a chance), so don't worry about that for now. I deliberately removed the reference for the Bosnian position because it was attributed to the Israeli government (not appropriate given the context). You were right to add that back since I didn't give an explanation in my edit summary. I've tagged it with an explanation, will remove it again tomorrow if nobody objects. Not a big deal. Thanks again, Nightw 21:43, 1 November 2011 (UTC)
Thanks too. I'm done editing the page and shall leave it to you and others to improve it :) Have a good day! cmɢʟee'τaʟκ'maιʟ 21:48, 1 November 2011 (UTC)

Transparent Background[edit]

Hi Cmglee. You do really nice work. I was wondering if the image found here could be uploaded with a transparent background? Bruhow (talk) 23:12, 8 November 2011 (UTC)Bruhow

Thanks, Bruhow. I've made the background transparent and improved the scale on the ground. Incidentally, could you forward me to a document that explains why it should be transparent? Wikipedia:Preparing_images_for_upload does not explain it. I can understand it lets images be used on different backgrounds without unsightly borders, but for graphs (especially colourful ones like this one), wouldn't that make certain parts unreadable? The white background guarantees that this cannot happen. cmɢʟee'τaʟκ'maιʟ 13:05, 9 November 2011 (UTC)

US standard atmosphere[edit]

Hi, the current version of the US standard atmosphere is 1976, not 1962. I think it would be better to use the current data for the articles you just added your 1962 image to. Q Science (talk) 06:10, 12 November 2011 (UTC)

Hi Q Science, I'm aware of that, but could not find any suitable graph of all 4 properties to trace. If you have one, or know the vertices of a piecewise-linear function (or quadratic/cubic Bezier curve), please let me know. Nevertheless, since NASA used it for their Centennial of Flight site, it shows at least some acceptance of the 1962 model. cmɢʟee'τaʟκ'maιʟ 15:57, 12 November 2011 (UTC)

The megametre is a perfectly valid unit in the metric system and is equivalent to 1000 km. I would have used "x000 km" instead, if there had been sufficient space in the diagram. cmɢʟee'τaʟκ'maιʟ 18:35, 29 December 2011 (UTC)

Addition of Comparison angular diameter image to Solar eclipse[edit]

I find this image redundant for the article. The article already has a chart showing the different apparent sizes of the sun and moon as seen from earth and I think the chart is easier to see what is going on than with your graph which seems to me a bit cluttered with all the circles so close together. In short I don't see how it adds to the article what isn't already there, furthermore I don't think it conveys very well, visually, the apparent sizes. Before I remove it, I figure it would be nice to get your feedback on my criticisms. Thanks. --TimL (talk) 01:33, 27 January 2012 (UTC)

Thanks for the note, TimL. I understand that there's a chart showing the apparent sizes (I made it!) but I find it very difficult to distinguish the sizes from the thumbnails; I suppose it's below my threshold of just-noticeable difference, whereas I find the image makes it clearer. Would it be less cluttered if only the sun and moon (and not the planets and ISS) are shown? cmɢʟee 13:05, 28 January 2012 (UTC)
thanks for the reply. In the chart, the moon seems quite visibly diffrent in size, the sun, not at all. So I partly agree with you about the chart. However, if one looks at the chart they can see the Sun's angular diameter varies very little, thus explaining why they look the same size in the chart. The problem I see with your diagram is all the circles are to thin and too close together to easily tell apart. Perhaps you could "zoom in" on part of the "disk" and create a figure showing just an arc (representing part of the full disk of sun and moon rather than the whole disk) whereby the differences in angular diameter could be "magnified" so to speak, leaving it an exercise for the reader to imagine the whole disk if they would like, which I think would be fine. Thoughts? --TimL (talk) 12:47, 1 February 2012 (UTC)

A preserved fruit bat showing how the skeleton fits inside its skin.
A preserved turtle skeleton showing how the carapace connects with the rest of the skeleton.

Thanks, Rock drum for the invitation but sadly I can't make this Sat.

Since you and User:HJ Mitchell are active in GLAM, I wonder if you've come across the Horniman Museum which I wholeheartedly recommend, especially due to their idea of comparing the same class of artifact from different cultures. They pride themselves to be a teaching museum, so may be keener than most to open their doors to Wikimedia. Sadly, I don't have a contact there, but their guides seemed quite open to ideas.

On my last visit, I photographed some specimens with skins/shells cleverly sectioned to show how the underlying skeleton relates to the rest of the animal (something I'd not seen before), as in these examples. Because they were behind glass, there were many reflections, and I could not get better angles. I think these are excellent illustrations of assorted animal anatomy, as I've done for turtle shell and bat#Wings. Under GLAM, the museum may briefly open the cabinets for someone to take better pictures.

I should thank both of you for your devotion to GLAM. Not many people would be willing to spend their time and effort organising such events. Keep up the great work!

Comparison highest mountains graphic[edit]

Very impressive work on this graphic [[1]]. I just saw your additions of it to the mountain lists. Overall I like it, but it could use some improvements. A couple things that jump out:

The use of the question mark really needs to go. It should be another symbol. The question mark being there makes it seems as though the author or someone is questioning the data or indicating that we are unsure about something.

Since Everest/K2 are members of both the 8000ers and the Seven Summits/Seven Second Summits, it would be nice if there was a more prominent way of indicating this fact on the graphic. Maybe with a unique color code or something just for these two peaks.

Just my own initial thoughts for now. Thnx --RacerX11 Talk to meStalk me 00:36, 5 April 2012 (UTC)

Thanks, Racerx11. I struggled to find symbols I could use. Strangely, non-ASCII characters e.g. † (dagger) failed to display in Firefox. Can you suggest some appropriate ASCII symbols? I thought the symbols were sufficient to show which sets each peak belongs to, and used colours to denote continents. How about if I use increased saturation to indicate the Seven Summits/Seven Second Summits? cmɢʟee 12:22, 5 April 2012 (UTC)
How about asterisk * and caret ^ or asterisk * and double **, any of those would be better imo, if they work. I see now that you used the color coding to denote continent. That makes sense so never mind about Everest and K2 with their own color, unless... It occurs to me if you color coded by list, one color for eight-thousanders, one for seven summits and a third for second seven, then it would make sense to have a fourth shade just for Everest and K2 to indicate membership in more than one list. Additionally you could could have different shades for Bass and Messner which would solve the non-ascii symbol problem. --RacerX11 Talk to meStalk me 17:56, 5 April 2012 (UTC)
Sorry, when I wrote the above, I wasn't considering that you were already using * and ^. I was just now trying to work it all out and come up with a scheme that solves everything. My mind started swimming. The more I look at it, the more I realize with what you were trying to do, what you have now is about the best it could have been. Just thinking out loud now. Could you color code for each list, including for Bass and Messner, or use * and ^ if needed, and then simply state the continents by name in text? Would that work?--RacerX11 Talk to meStalk me 15:08, 6 April 2012 (UTC)
I think have something I would prefer: Use just three colors. One for each list. Then use ^ to denote Messner and * to denote Bass for both of the seven summit lists. Simply enter the continents using text below each mountain name. So for example Mount Townsend would be colored using the seven second summits color and the text would look like:
Mount Townsend*
2209 m
Australia*(asterisk optional here)
(with * denoting Bass list)
As for Everest and K2 belonging to more than one list. Make the triangular peak graphic a two-toned image for those two peaks only. For example, one half of K2's triangle would be colored with the eight-thousander color and the other half colored with the seven second summits color. Follow me? Wouldn't that work or am I overlooking something? --RacerX11 Talk to meStalk me 15:37, 6 April 2012 (UTC)
Wow, thanks for putting so much thought into this, RacerX11. I like your 3-colour image idea, except that it might be confusing for Everest and K2 to be half one colour and half another. I could stripe them as in File:Prevailing world religions map.png, but I think I've an idea where it's the labels that are grouped (though requiring Everest and K2 to have repeated labels). Give me about 3 hours to come up with something... cmɢʟee 15:47, 6 April 2012 (UTC)
Great! My suggestions are mostly intended as food-for-thought or maybe something that would strike you as a good idea to improve on. Will wait to see what you come up with. Take as much time as you need. No one is in a hurry over this. --RacerX11 Talk to meStalk me 16:07, 6 April 2012 (UTC)

Thanks for the barnstar[edit]

Hi, thanks for the barnstar. My first ever !

Just a note on the sRGB data for the ColorChecker card, there are a couple of people in the external links on that article [ Bruce Linbloom and Danny Pascale and both seem to know what they are talking about] and from what I can make out they both conclude that the manufacturer's sRGB data isn't particularly accurate.

I wanted to added Bruce Lindbllom's sRGB data to the article but I don't quite know how to justify including his data [is he a keen amateur or a credible source of info on the topic? Or both!] He has links on quite a few Wikipedia articles to do with colorimetry etc. I'd be fairly sure he knows his stuff but I can't quite get my head around citing his data.

Anyway, thanks again for the barnstar.Sun Ladder (talk) 11:41, 21 April 2012 (UTC)

You're welcome, and thanks for the note, Sun Ladder. I've read some articles by Bruce Lindbloom and he indeed seems quite knowledgeable. In this case, I'm unsure what the best approach is, too. I would open the topic to general debate on the ColorChecker talk page by copying what you wrote above there (I can do that for you if you like). If there's no reply in several days and you feel strongly about it, perhaps you could add his data to the ColorChecker article with a reference? Just a thought... cmɢʟee 12:09, 23 April 2012 (UTC)

Comparison angular diameter image for Solar eclipse[edit]

Fixed Sun labels

Hi. Unlike one of the previous commentators, I think this image is a terrific addition to the Solar eclipse article. However ...

The caption stating the maximum and minimum angular diameter of the sun (in actual numerals) cannot be correct because it indicates that the maximum diameter is less than the minimum. I would correct this if I knew how, which I do not.

Furthermore (but less important) the numbers shown do not correspond exactly to what is shown in the table of values within the Solar eclipse article itself, even if they were to be reversed, as apparently they should be. This is a less interesting issue than the reversal, since the discrepancy of the values is small, although I do not know the source of this discrepancy. Paul (talk) 22:19, 28 May 2012 (UTC)

p.s. By the way, you do great work on a variety of images, which have become some of the highlights of Wikipedia. Paul (talk) 22:19, 28 May 2012 (UTC)

Thanks and well-spotted, Paul. I've fixed the labels as on the right. The values in the graphic were from the How long will we continue to be able to see total eclipses of the Sun? answer at NASA, but there is a mistake: "...the Sun's angular diameter varies from 32.7 minutes of arc when the Earth is at its farthest point in its orbit (aphelion), and 31.6 arc minutes when it is at its closest (perihelion)." It should appear smaller when farther, so the values should be swapped. I've updated the table and noted this mistake. cmɢʟee 13:11, 31 May 2012 (UTC)

Thanks for the fix. For a minute there, it appeared that the values in the image caption were still wrong, but in reality I simply needed a judicious dose of "F5" (refresh). And then it was all clarified. Paul (talk) 19:43, 31 May 2012 (UTC)

Panamerican Peaks[edit]

Thanks for the great graphic. In 2009-2010 I embarked on my adventure of a lifetime called Panamerican Peaks: Cycling between Alaska and Patagonia (Panamerican Highway) and Climbing the highest peaks of every country along the way.

Thanks. I've replaced the Eight-thousanders of File:comparison_of_highest_mountains.svg with your list. If you know the Perl programming language, you can extract the Perl code at the bottom of the SVG file and make your own graphic, too. Congratulations, by the way, on your successful climb! cmɢʟee 20:12, 7 June 2012 (UTC)
Hi Cmglee,
Thanks for turning this around so quickly. I see from the svg file that you just had to replace the driver table for your Perl script and some of the color assignments. Pretty nifty script there - have never written Perl myself.
Did you start out with a drawing tool (like Adobe Illustrator), save in .svg and then refine with Perl? Or did you start from scratch with Perl?
On the color assignments, perhaps one could use the green and blue (for North and South American Panamerican Peaks) instead of the yellow. ::Also, the fact that Denali (=McKinley) and Logan are listed multiple times is a bit confusing.
Anyway, I added it to my most recent Blog post at
Thanks again,
Thomas Laussermair
Hi Thomas,
Thanks. I just visualised it on paper and directly wrote the Perl script to plot it. Of course, the design changed quite a bit as I went along.
If you wish to fix the graphic or plot your own mountains, first get a copy of Perl (I recommend ActivePerl) and a Perl tutorial. Knowing how obfuscated Perl can be, I've tried to write it as simply as possible. If all you want to change are the mountains and colour assignments, just edit the string $data_string and hashtable %continents. Each line in $data_string corresponds to one mountain belonging to one of the continents (loosely used to mean "category"). The fields, delimited by "|" are
  1. x-coordinate of centre of mountain and label
  2. y-coordinate of baseline of label
  3. continent code
  4. rank in continent
  5. height in metres
  6. name
They are plotted in the specified order, so earlier ones appear "behind" later ones. The %continents structure should be self-explanatory.
Good luck! cmɢʟee 23:19, 14 June 2012 (UTC)

Seven Second Summits map[edit]

Hello again. The map you have added at Seven Second Summits has a small issue for me. It indicates Puncak Trikora as the second highest point of Australasia/Oceania/New Guinea, (Messner list). The discussion about Puncak Mandala vs Trikora as the true second highest is at Talk:Seven Second Summits#List may be incorrect. The consensus reached from that discussion was that Mandala is higher and we made made all the changes in all related articles based on the best information from reliable sources we could find. We have also left notes on certain articles explaining that the two peaks are very close in height and some sources may list Trikora as higher and/or being a member of the Messner list. The most recent and accurate data does support Mandala being higher (note however, user:Viewfinder does add that this is "not 100% conclusive").

So alas the map is somewhat contradicting what the article currently states. Possible solutions:

  • 1) Edit article to explain or reflect what the map indicates.
  • 2) Replace map with one that instead, displays Mandala as #2.
  • 3) Simply delete the map.

Thoughts? --RacerX11 Talk to meStalk me 01:34, 13 July 2012 (UTC)

You might want to note that there's a public domain flag on the Commons that you might need to address for the image. Images always scare me so I'm not entirely sure what the flag is...

Since you seem to be an image specialist, have you looked at the following script: User:Dapete/ImageMapEdit.js? Imagemaps seem precisely up your alley.

Many thanks for creating the image map and notifying me about the mistake, ResMar. I've fixed Merapi's year, but I'm unsure by what you mean by "root protection" — I create the SVGs by hand in a text editor, so perhaps Inkscape or another graphics editor doesn't like the formatting. Converting a bitmap to SVG is very difficult by hand, so I've to leave the task to someone more familiar with Inkscape etc. Though WIkipedia prefers SVGs, I think the GIF is fine (I can convert it to PNG if needed) especially since the USGS is a public domain source. I'm unfamiliar with image maps, so can you tell me how to use ImageMapEdit.js? cmɢʟee୯ ͡° ̮د ͡° ੭ 03:04, 26 January 2013 (UTC)
It's a tool that loads onto the page whenever you end up at an image. It adds a button below the image that lets you map coordinates, assign links, and etc. for imagemaps. I tuned Template:Volcanic Eruption Map using it, for instance, and I think you would find it handy given that you're a technical graphic contributor. Just looking at your talk page it would be useful for File:Moon landing sites.svg and File:Comparison of highest mountains.svg As for the map, that would explain it, I don't have experience with Inkscape's raw XML editor (or, really, raw XML, yeah, I know).

2013 Lahad Datu standoff.svg

Hi, I think that the map needs to be modified. Mindanao can be regarded as a province in the illustration and Zamboanga is its capital. What I can suggest is we change the font size of Mindanao as well as Zamboanga's, and adding Bongao as the capital in addition with the existing Simunul marker. If I may add, Sipadan is irrelevant to the ongoing conflict in Sabah as this pertains only to the 2000 Kidnapping incident in which Kirams or the Malaysian government is not a part of it. Thanks! adkranz (talk) 02:05, 5 March 2013 (UTC)

Thanks for your feedback, Adkranz.
  1. I'm unsure what you meant by the first part. Do you mean that Zamboanga is incorrectly indicated as the capital of Mindanao? I've updated the markers to show that it is a city but not the capital.
  2. Tawi Tawi is already too crammed to fit a Bongao marker. Besides, it's not mentioned in the article.
  3. I think the 2000 kidnapping is wholly relevant as it's another "terrorist" (for lack of a better term) incident by another militant group in the vicinity. I've made the font smaller to deemphasise it.

State election results template[edit]

  • Regarding the extra column in the Template:Malaysian general election state results, 2013, I don't see it as necessary. We already have the number of seats in Barisan, Pakatan and Independents and their variances, including the totals. Can you explain by what you mean when you say changes in the number of seats for each state? There hasn't been any changes in the number of seats in states for the past 10 years or the introduction of new state seats. This procedure I believe is only done every 10 years due to population changes in the country.Lazybugger13 (talk) 07:41, 11 May 2013 (UTC)
  • Hi Lazybugger13, if you look at the +/- columns for Kedah and Selangor, the sum of all the parties' values is not zero (e.g. Selangor has BN losing 9 and PR gaining 10, implying that one new seat has been created). Since you wrote, "There hasn't been any changes in the number of seats in states for the past 10 years or the introduction of new state seats," does that imply that the numbers in the table are wrong? cmɢʟee୯ ͡° ̮د ͡° ੭ 21:08, 12 May 2013 (UTC)
Hi guys, sorry for interjecting your conversation, but allow me to clarify a few things on this topic. Indeed, there's no change in state assembly seats between 2008 and 2013. However, there could be changes within that period like by-elections and passing of an assemblyman, which is reflected in List of State Seats Representatives in Malaysia (before GE13). If you refer to that article for the changes in seats, you might find that the figures don't add up properly, as in the Selangor example.
Vacant seats should not be considered "missing" in 2008 results and "added back" in 2013. Still, it's not clear whether you want to base the changes on the 2008 elected results, or up to the point before GE13, including by-elections and changes of allegiance. Hytar (talk) 21:51, 12 May 2013 (UTC)
Hi cmglee, actually when I started the summary table I was basing it from the List of State Seats Representatives in Malaysia, whereby for example Selangor has 56 seats. There hasn't been any new seat created in Selangor since the the 2008 general elections. Going through the Selangor list again, BN has 21 seats, DAP has 12 seats, PKR has 14 seats and PAS has 8 seats (this gives PR 34 in total) and one vacant seat(due to the passing of assemblyman Edward Lee from DAP on December 2011). Now BN won 12 seats (meaning they lost 9 seats), PR won 44 seats (meaning they won 10 seats, including the vacant seat). Now regarding Kedah, we got BN at 14 seats, DAP 1 seat, PKR 2 seats, PAS 16 seats(This gives PR 19 seats in total) and 2 independents. The recent election saw BN winning 21 seats (gain of 7 seats, meaning they scooped up both the independent seats too and 4 PR seats) and PR gaining 15 seats (lost of 4 seats). So in a way the table is correct and those need an extra column on seat variances next to the total. As Hytar mentioned we are looking at basing the changes up to the point before the GE13 taking into account, by-elections and changes of allegiances.Lazybugger13 (talk) 08:29, 13 May 2013 (UTC)
My apologies regarding the previous post regarding Kedah. In actual fact let's summarise the Kedah list again. I shouldn't have taken the list at face value without checking it thoroughly. BN has 14 seats, DAP 1 seat, PKR 4 seats, PAS 16 seats (this gives PR 21 seats) and 1 independent This gives us 36 seats in total. Recently BN won 21 seats (a gain of 7 seats) and PR has won 15 seats (a lost of 6 seats) and the independent lost his seat. So in actual fact the table has to be tweaked with new corrections.Lazybugger13 (talk) 08:49, 13 May 2013 (UTC)
Thanks for the detailed analysis, Lazybugger13. In that case, I agree with you that the +/- column in the table is redundant. cmɢʟee୯ ͡° ̮د ͡° ੭ 11:07, 13 May 2013 (UTC)


Do you still have the code you used to generate the 5 way Venn diagram? I would like to know the center of the ellipsis; hence I'm asking. Thank you. Carstensen (talk) 11:00 am, 16 April 2013, Tuesday (1 month, 30 days ago) (UTC+1)

Hi, Carstensen. I've just seen your message as I'm notified when someone edits my user talk page but not my user page, so please drop me a message at my user talk page in the future. To answer your question, the code is in the SVG itself (that's the beauty of SVG). This is the relevant part:
<ellipse id="ellipse" cx="36" cy="-56" rx="160" ry="320" />
i.e. if the centre of rotation is at (0, 0), and ellipse A's major semi-axis is 320 and minor semi-axis is 160, its centre is at (36, -56). Hope that's useful! cmɢʟee୯ ͡° ̮د ͡° ੭ 23:36, 14 June 2013 (UTC)

TemplateData is here[edit]

Hey Cmglee

I'm sending you this because you've made quite a few edits to the template namespace in the past couple of months. If I've got this wrong, or if I haven't but you're not interested in my request, don't worry; this is the only notice I'm sending out on the subject :).

So, as you know (or should know - we sent out a centralnotice and several watchlist notices) we're planning to deploy the VisualEditor on Monday, 1 July, as the default editor. For those of us who prefer markup editing, fear not; we'll still be able to use the markup editor, which isn't going anywhere.

What's important here, though, is that the VisualEditor features an interactive template inspector; you click an icon on a template and it shows you the parameters, the contents of those fields, and human-readable parameter names, along with descriptions of what each parameter does. Personally, I find this pretty awesome, and from Monday it's going to be heavily used, since, as said, the VisualEditor will become the default.

The thing that generates the human-readable names and descriptions is a small JSON data structure, loaded through an extension called TemplateData. I'm reaching out to you in the hopes that you'd be willing and able to put some time into adding TemplateData to high-profile templates. It's pretty easy to understand (heck, if I can write it, anyone can) and you can find a guide here, along with a list of prominent templates, although I suspect we can all hazard a guess as to high-profile templates that would benefit from this. Hopefully you're willing to give it a try; the more TemplateData sections get added, the better the interface can be. If you run into any problems, drop a note on the Feedback page.

Nice graph. When you get the time, would it be possible to add the unit of the "perch" (sq. rod) to the chart? As the acre is defined as 4x40 of these originally, it is a more important unit than the square chain to have a comparison.

Also, the rood, quarter acre is also used for subdivisions that don't simply decimalize acres for sale. In Sri Lanka, Jamaica, and at one time in all countries that used acres for land, deed descriptions were broken down ACRE, ROOD, PERCH.

In any case, this is a great visualization. Thanks for adding it! Surveyor792 (talk) 23:20, 11 August 2013 (UTC)

Million Award[edit]

Hi Cmglee,

In a few days I'm going to be starting a new Wikipedia award that I'm tentatively calling the Million Award. You can read details about it at User:Khazar2/Million, but the basic idea is to reward editors who bring a particularly high traffic article to GA or FA to encourage work on our most-read articles.

The biggest problem I've run into is creating an image. I have zero skill in graphic design, and a "million" is hard to represent in userbox size. I was toying with the idea of adapting your visualization of 1 million in some way--perhaps as simple as this--but it occurred to me that I might ask you for help directly. Would you have any interest in helping with a graphic or graphics for this award?

Since this is for user pages only, it doesn't need anything fancy; anything you'd be willing to slap together would be a huge help. The only trick is that it has to look good at 42px or so in order to go into a userboxes as well as a barnstar, or have some variation that can be reduced to 42px. Eventually, I hope to make separate images for the three different tiers of the award (Quarter Million, Half Million, and Million), but any image will do to get the ball rolling.

What do you think? If there's any way we could work out a labor trade, I'm always up for copyediting, reviewing, etc. In any case, thanks for all your terrific image work--I really enjoyed looking over your userpage, especially the peripheral drift illusion. -- Khazar2 (talk) 05:15, 26 August 2013 (UTC)

Oh, sorry. The correct link is here. You can see a very early draft of how it might look here, though I'm still playing with formatting, colors, etc. Feel free to start from scratch, though, if it's easier--I really appreciate the help. -- Khazar2 (talk) 12:00, 27 August 2013 (UTC)
Thanks. I had a look at your work with Wikipedia and am really impressed with what I saw!

Comparison of pyramids.svg[edit]

Hi! I am interested to know why the Etemenanki is left out of your very nice graphic comparison of pyramids? Is the reason that you only include still existing pyramids? I personally think it could be included because it was big (91 meters high), is a step pyramid comparable to the Mayan ones (like Chichen Itza) and it has a great historical significance (tower of babel). What do you think? ;-)

Greetings -- Weapon X (talk, contribs) Germany 01:43, 30 November 2013 (UTC)

Thanks, Weapon X. To be honest, it was a simply a case of not being aware of Etemenanki before you told me about it. It certainly has a very interesting history. Nevertheless, I'm not sure about including it because:
  • It no longer exists, as you noted.
  • The graphic is already pretty crowded.
Any thoughts? cmɢʟeeτaʟκ 23:38, 1 December 2013 (UTC)
Yes, that it no longer exist is a good reason for not including it! But I personally would much more love to see it included then the three biggest "pyramids" (Ryuyong Hotel, The Shard, Transamerica Pyramid) because they all are just present day skyscrapers who are mimicking a pyramid but aren't exactly one (same counts for the Burj Khalifa which looks like a kind of step pyramid.) On top of that these three biggest pyramids squash the other pyramids in the lower part of the graphic which makes it more difficult to view.
What about one graphic of still existing pyramids (in their nowadays height) and one with historical pyramids with their original height and shape (including Etemenanki and Pyramid of Djedefre)? Just a though... -- Weapon X (talk, contribs) Germany 17:31, 5 December 2013 (UTC)
That's a good idea, Weapon X. Would you be willing to make a start? You can just take my image and remove the modern ones — each has its own SVG group — and add the 2 new ones. Alternatively, if you can draw their silhouettes at a scale of 1 SVG unit/metre and either upload the SVG or paste the code below, I can include them and remove the modern ones this weekend. Cheers, cmɢʟeeτaʟκ 20:12, 5 December 2013 (UTC)
Hi cmglee, sorry it took so long for me to anwer... Unfortunately I am in no way familiar with SVG graphics yet. But it would be an interesting way to get familiar with it (if I ever find the time for it... could take month ;-D). -- Weapon X (talk, contribs) Germany 14:55, 7 January 2014 (UTC)
No worries, Weapon X. Writing raw SVG (like HTML) can be very tedious compared to using a visual editor but one has great control over the output, and one can write scripts in assorted languages (I use Perl mostly) to automate its production, which makes it quite powerful for visualising data e.g. graphs. Let me or editors at the Commons Graphics Village Pump know if you need any help with it! cmɢʟeeτaʟκ 20:19, 7 January 2014 (UTC)

Singing on the River[edit]


I've been editing the Trinity College, Cambridge page to update the 'Masters of the College' section, and noticed that your Singing on the River photo is very dark (especially noticable in the thumbnail). Might it be tweaked to show things more clearly? I've done a quick fix using Preview which you can see at (I've moved it to a different folder; see below for details), which you are welcome to use if you wish (I started with the full size picture to produce this), though you might be able to make a better version with jazzier software. By the way, the conductor is Trinity's Director of Music, Stephen Layton, if you'd like to add that somewhere appropriate. --Brian Josephson (talk) 09:50, 9 March 2014 (UTC)

Thanks for your work on the article and picture. I've brightened it as far as I dared without the noise becoming overwhelming (the picture was taken at high ISO) and uploaded it. I also added your comment about the conductor to the image's description. cmɢʟeeτaʟκ 23:21, 9 March 2014 (UTC)
I see your point about noise, in the reflections of the trees in the river particularly, though that is only apparent with very large image sizes which most people will not use. By increasing the contrast it is possible to make the picture brighter while keeping the tree reflections very dark so the noise becomes less conspicuous. I've made a quick attempt at this, and you can see both in a single folder,, so you can compare the two easily. I must say I prefer it lighter even if that means not making it available at super-high resolution (but then again it might be argued that the darker one better represents the reality), but of course there's no reason why both can't be made available even if only one is linked directly to the article. --Brian Josephson (talk) 10:15, 10 March 2014 (UTC)
Am I right in thinking that not all of the different size versions have been brightened? It looks to me as if only the 3,072 × 2,048 pixels and 1,280 × 853 pixels ones have been reprocessed and the others are still dark. It would be good if you could brighten the 800 × 533 pixels one as well as that's the one that shows by default when you click on the thumbnail. But it looks as if that might not be under your control? --Brian Josephson (talk) 16:42, 11 March 2014 (UTC)
I've no control over the Mediawiki software in this respect: all thumbnails are generated from the same source image. Some thumbnails may appear darker because they are the old versions which it has not yet updated, but they will change in due course.
I'll employ a workaround using the Annotated image template to crop the thumbnail on the page. Let me know what you think. cmɢʟeeτaʟκ 20:52, 11 March 2014 (UTC)
Actually, I think it is better uncropped as with it cropped you don't get so much of a sense of the watching crowd, which adds atmosphere, though a lesser crop could work. Also I don't think it is good having the singers so close to the left side of the frame, but I suppose you don't have much control over that. The darker images are still dark at this time, but in any case the current situation is a lot better than at the start where the thumbnail on the main page was a lot too dark.
Update: it looks like the update robot has now brightened all the images. My feeling now about cropping is that the most aesthetic crop would be to crop the left side so that the illuminated window in the background just fits in. But it's really up to you to decide as it's your photo.
If I went last year (I'm not sure if I did or not), we would have been quite close to you! Perhaps we'll meet at a Cambridge gathering some time -- I hadn't realised such things existed till I stumbled on that page by accident.--Brian Josephson (talk) 21:32, 12 March 2014 (UTC)
Are you still in Cambridge? If so, I'd love to meet you at an upcoming meetup where editors can talk about not only Wikipedia but also other Wikimedia ideas.
As for the picture, I don't mind your editing the page any way you see fit. Feel free to revert my crop. The other thing you could do it's to upload your brightened version (we'll have to fill an OTRS form for me to do itt.), display it as a thumbnail, and make it link to my original when someone clicks on i you upload it,t. If you're unsure of the Wikitext syntax, once tell me and I'll update the article. cmɢʟeeτaʟκ 22:21, 12 March 2014 (UTC)
I don't have time for the complexities of replacing your picture with my adjusted version, but have adjusted the parameters for the thumbnail so as to rebalance the picture.
I am still in Cambridge, but I see the next future meet is last year(!) and I don't possess a time machine ... but I'll watch for it. Perhaps Cambridge can figure out a way to deal with the 'teenage gang' problem (see my compilation The World is Watching) which seriously disrupts some of the pages I've been trying to make better balanced. --Brian Josephson (talk) 10:04, 13 March 2014 (UTC)
I didn't realise you're Professor Josephson; it's an honour to communicate with you, Sir! Sorry, I overlooked how out-of-date that page is; this is a more recent one, but there doesn't seem to be one planned for Cambridge, UK.
I support your views on "teenage gangs". I suppose one of the traits of Wikipedia is its overturning of structures of authority, where supposedly all edits, whether from Nobel laureates or teenage dropouts are given the same amount of importance or respect, and only references from reputable sources matter. However, as with any large human system, a new power structure has emerged, just as in other volunteer-based organisations I've experienced. I just try to stay clear of hotspots and do illustrations on concrete topics which I find less contentious.
Incidentally, if you've any topics in your field you think could be improved with an illustration, please let me know and I'll see if it's within my abilities! cmɢʟeeτaʟκ 23:29, 15 March 2014 (UTC)
I've had another go with the Singing on the River thumbnail as you may have seen. I guess one has to choose between a good view of the singers, or getting the overall atmosphere including the audience, you can't have both in the thumbnail as it is so small (and I reduced the height slightly in my latest to get better framing).
The RS constraint would matter less if the teenage gangs didn't impose their own interpretation (as they do with 'fringe topics', which is more serious; defining something thus legitimises all sorts of damage). When you say 'new power structure', are you referring to the structure I'm familiar with, which empowers the gangs, or is that changing?
Re your query about illustrations, there's a nice picture by Debendetti and Errington, in, of a 15-molecule water cluster obtained by computer simulation (molecules cluster in such a way as to maximise the space they take up) which could illustrate the memory of water page (Debenedetti has sent me a colour version), but there's absolutely no point in making a graphic from that for the water memory page as the cabal would instantly cook up some reason for removing it. But the simulation does nicely refute the common view that liquid water is just separate molecules -- the clusters in the simulation are very specific. --Brian Josephson (talk) 09:59, 16 March 2014 (UTC)
Well done on the thumbnail, Brian. Since we're on this subject, I wonder if you've any opinion on this topic: Talk:Trinity_College,_Cambridge#Singing_on_the_River.
About "gangs", I think it's a broad label that covers people with an agenda (beyond presenting facts as neutrally and truthfully as possible) to push. What constitutes a reputable source is difficult to define, and everyone draws the line differently.
I had a quick look at your paper and it's certainly beyond my knowledge scope to evaluate it. It seems like a different phenomenon from this article. If so, I think it's rather unfortunate that they share the same name, as the latter is not very highly regarded (putting it mildly). cmɢʟeeτaʟκ 13:15, 19 March 2014 (UTC)
I've tracked down the situation re earlier singing on the river, it was the CU Madrigal Society: see the edits on the page. Re the memory of water, the authors did a computer simulation showing that large clusters of water molecules form according to it. This in theory could provide a mechanism for memory, though their simulation doesn't show how long the clusters last. But I suspect a subtler and more global organisation (cf. quasicrystals) is the mechanism for memory.--Brian Josephson (talk) 16:50, 19 March 2014 (UTC)
Thanks for researching and updating the Singing on the River society. By the way, I've just spotted a little coincidence that someone had added a photo I took of the Wren Library to your page! cmɢʟeeτaʟκ 13:31, 24 March 2014 (UTC)

Why constellations are defined the way they are[edit]

I found myself on your user page following a watchlist notification and noted that you were surprised at the fact that constellations are defined by astronomers as regions of the sky rather than the familiar star groupings. The explanation is very simple: it is a way to indicate roughly where in the sky an object such as a comet is at any given time, without the observer needing to have a star atlas handy to get the precise location. So for example if you are told that a certain comet is in Gemini, you look up and find Gemini the star group in the sky, and that will be roughly where the comet is. --Brian Josephson (talk) 11:36, 3 April 2014 (UTC)

Thank you, Brian. That makes sense, as defining it by celestial coordinates rather than stars allows new discoveries to be unambiguously assigned to a constellation. On the other hand, as stars move in the future, the stars which lay-people consider part of a constellation may no longer be in its coordinate-based one. cmɢʟeeτaʟκ 12:11, 4 April 2014 (UTC)
In fact, coordinates change in any case, owing to the precession of the equinoxes. That is a much faster change than that due to the movements of the stars. My first Norton's Star Atlas was 'Epoch 1950' and now I have 'Epoch 2000' -- presumably there was enough change over 50 years for it to be considered good to change the defining epoch. But presumably the constellation boundaries are defined relative to some galactic coordinate system, and are unaffected by precession of the equinoxes, so you will be pleased to know that wikipedia users a century hence will still be able to use your chart! But, as you say, the constellations will look different if we go a million or so years into the future. If you're wondering why astronomers use these funny moving coordinates, by the way, the answer is that they are used to point telescopes in the right direction -- the axis of the earth slowly changes over time, and as telescopes are grounded in the earth corresponding changes have to be made in how they are set.
If I may marginally shift topic, it is often said that the 'year 2000 bug' was overblown. I know of two exceptions to this. One was a telephone service provider that ceased operating early in the year 2000. The evidence pointed to the reason for this being that a year 2000 bug caused them to lose credit card and other customer details so they could no longer bill customers for their phone usage. The other was a computer controlled telescope I had which stopped being able to locate stars after 2000, but could do it correctly if you reset the time to the same date in a previous year. --Brian Josephson (talk) 08:44, 5 April 2014 (UTC)
Thanks for the insights, Brian. I suppose an even smaller effect is plate tectonics! As for the Y2K non-event, I felt at the time that the media response was uncalled for; engineers all around the world including myself spent effort testing and fixing systems so they wouldn't fail. If we hadn't and things went wrong, they would've blamed us for not taking it seriously enough! cmɢʟeeτaʟκ 18:19, 7 April 2014 (UTC)
I remember now the pieces of evidence re Y2K. One was that the company informed customers that they had a system problem and you couldn't do something or other until this was fixed. And then they announced they were ceasing their service. The final bit of evidence for my theory (together with the fact that it was not long after the beginning of 2000) was they never collected the amount owing to them for the phone calls made since the last payment!
But I recall another company that ceased some service and tried to keep the money remaining on one's account. When I complained, they said the T&C said that if an arrangement was terminated there would be no refund if the amount in the account was less than £15. Obviously that applied only if it was the customer who wanted to terminate the agreement not them, and sensing I was an awkward customer they refunded the balance in due course. --Brian Josephson (talk) 18:49, 7 April 2014 (UTC)

(A), (B) and (C) are indications of audience: A is introductory, B is the level of everyday editing on Wikipedia, and C is advanced. X is very advanced (expert). These things are explained on the VLE itself in the basic "General Introduction". Charles Matthews (talk) 19:52, 8 April 2014 (UTC)

Can you do this?[edit]

Please take a look at this suggestion. — Preceding unsigned comment added by UA Victory (talkcontribs) 16:37, 21 April 2014 (UTC)

I'm sorry, UA Victory, but your request is beyond my abilities. I'd suggest just cropping the corresponding area from OpenStreetMap and cite it as appropriate. cmɢʟeeτaʟκ 20:09, 21 April 2014 (UTC)
Well thanks for your reply, but the map from OpenStreetMap won't do it because it reflects the current situation. I want the map that shows the historical situation. --UA Victory (talk) 20:26, 21 April 2014 (UTC)

Lego dimensions[edit]

New version

Hi Cmglee,

If I understand well, you are the author of the dimensions diagram on the Lego page (

I carefully measured dimensions for the purpose of 3D modelling, and arrive at different values for the diameter of the knobs.


as well as

I think the wikipedia image has to be changed. Comments welcome.

Hi Robert,
Excellent work on finding out the dimensions, especially rotating a 1×1 brick 45° to find the stud diameter. While Wikipedia doesn't normally accept original research, I suppose this is the best source I could find, so I'll accept your values.
I don't fully understand why you have 2 sets of outlines: black solid and red dashed ones. Just based on geometry arguments alone, if the stud pitch is 8 mm and stud separation (equal to plate thickness) is 3.2 mm, wouldn't the difference necessarily be 8 - 3.2 = 4.8 mm, unless the stud separation is slightly smaller and they move apart/are compressed when a plate is inserted?

Quayside photos[edit]

Thanks for the Quayside photos, they're good. I added one to the punt article, sometime I'll add a section about punt touts. Edward (talk) 12:23, 18 May 2014 (UTC)

Titanic passenger article[edit]

Looks great! I think probably the only criticism I have for the image itself is that it maybe needs a key? It's hard to see what the little symbols mean. Otherwise, great job! Morhange (talk) 03:55, 28 May 2014 (UTC)

Thanks. I've added a key and made the symbols the same. Better? cmɢʟeeτaʟκ 19:04, 28 May 2014 (UTC)

Comparison of nominal sizes of primary mirrors of some notable optical telescopes (click for detail)

First, I really like the graphic as it shows the size of modern optical telescopes.

I did note one error, the Very Large Telescope (VLT) is not located on Mauna Kea but rather Cerro Paranal in Chile. As a side note, while the Large Binocular Telescope is indeed located in the Pinaleño Mountains, the site is almost always referred to as Mount Graham.

Thanks for your contributions to the community.

Map of the crash of Malaysia Airlines Flight 17[edit]

Recoloured rest of Ukraine

Hi! You wrote:

The map needs labels, especially for the more important dots. I can add them if someone can identify the places (if so, please leave a message on my Talk page).

I can help with it. All the labels are on this map (the crash site map was actually based on an early version of it). Labels are in Russian. If you don't speak Russian, I can help with translation. --Alex1961 (talk) 10:55, 23 July 2014 (UTC)

Thanks, Alex1961. I don't speak Russian, so any help will be appreciated. I think only the major place-names need translation. cmɢʟeeτaʟκ 11:13, 23 July 2014 (UTC)
I've added some labels. Please feel free to make any edits. --Alex1961 (talk) 12:22, 23 July 2014 (UTC)
That's excellent! I've made the colour of the rest of Ukraine light orange to make it more distinguishable from that of Russia. cmɢʟeeτaʟκ 12:45, 23 July 2014 (UTC)

Sequential colour scale[edit]

Hello, do you remember your reuploading of this map? Where you found this colors, and do you help me with this? What's program you used, that generate this sequential color scale. I want use same color scale for another maps, but I don't know what color needed for...em... digit 6. :) I hope you understand me, because I like this color scale. Thanks. ← Alex Great talkrus? 11:48, 31 July 2014 (UTC)

Thanks for the compliment, Alex. I generated the colours by eye and not with a program. A sensible colour for "6" could be #cc00cc. Below is the complete sequence. I've slightly lightened "5" so they can be more easily distinguished. cmɢʟeeτaʟκ 15:34, 31 July 2014 (UTC)
0 1 2 3 4 5 6 7
Well, you have a very good color perception. But what happens when the number of wins of any country exceeds 7 times? ← Alex Great talkrus? 02:48, 3 August 2014 (UTC)
Perhaps I just have a good monitor! "But what happens when the number of wins of any country exceeds 7 times?" is a good point. Guess one will just have to come up with another colour. On the other hand, the number of wins is boundless, so there might be a problem sooner or later. Let's cross that bridge when we come to it. cmɢʟeeτaʟκ 12:01, 4 August 2014 (UTC)
I totally agree. In any case, it is possible to offer any other scale that, for example, be generated automatically (for example, the same function available in the Microsoft Office Excel). ← Alex Great talkrus? 12:39, 4 August 2014 (UTC)
If you haven't seen a method using the golden ratio, please see this page: I've also been reading about Halton sequences, which can be used to pick a point in 2D colourspace (I don't know how optimal that would be, though). cmɢʟeeτaʟκ 18:02, 4 August 2014 (UTC)

Japanese Calendar Image[edit]

Regarding the addition of the Japanese calendar to the Gregorian calendar article, since the Japanese use a modified Gregorian calendar it's a bit odd to find it there. Might it be better suited to the Japanese calendar article? JMJimmy (talk) 22:54, 20 August 2014 (UTC)

Considering the language used in the calendar and the author, the calendar was in no way Japanese, except in style (likely for Victorian exotic tastes). cmɢʟeeτaʟκ 23:01, 20 August 2014 (UTC)
Actually it was Japanese, see stamp, the publisher was known for producing this style of book in a dozen European languages. They had Japanese artists doing the work and hired prominent foreigners transliterate from Japanese tales/poetry. The colophon in the back of this particular one indicates it was the year Meiji 31. The story itself is about a 3day festival that takes place around the end of February in Japan. JMJimmy (talk) 00:45, 21 August 2014 (UTC)

Cambridge meetup 20 September and Wiki Loves Monuments[edit]

The next meetup falls during Wiki Loves Monuments. Do you have some good idea of an event we could run in Cambridge related to WLM? Charles Matthews (talk) 10:04, 2 September 2014 (UTC)

There is an automatically-generated map I have just found. Charles Matthews (talk) 16:06, 2 September 2014 (UTC)\

Thanks for your note, Charles. If the weather is fine, I'll be glad to show or accompany anyone around either by bike or on foot.
I suggest a themed tour e.g. the bridges, churches, museums or even sundials in Cambridge.
More conventionally, we can visit and photograph some Grade I listed buildings in Cambridge, or can take a few people into the colleges (say, up to 5). Punting is another option, though that's more social!
Any thoughts? cmɢʟeeτaʟκ 20:59, 2 September 2014 (UTC)
P.S. Went on this tour last year and loved it. I can follow roughly the same route if people are interested. (People are responsible for their own safety, bringing their own bikes etc.)

Interesting! Could you fit a tour into two hours, so that it ran for example from a 1 pm rendezvous, to a 3 pm finish at CB2? Charles Matthews (talk) 08:35, 3 September 2014 (UTC)

Would you know if the participants
  • Are already familiar with Cambridge, and
  • Have bikes?
I can't think of many interesting sites within a short walk of CB2, perhaps except the ARU campus (which I'm not too familiar with) and Parker's Piece (home of football and Reality Checkpoint). Do you have anything in mind? cmɢʟeeτaʟκ 23:36, 4 September 2014 (UTC)

I can't say who would come - maybe people from London, for example. That would be one reason to have an event before the meetup itself.

I'm quite interested in monuments in Chesterton. There is Chesterton Tower at . It is really the same site as Chesterton Abbey, which is one of the listed monuments. There are two photos of the Tower on Commons at present, one from Geograph. This is up to 30 minutes walk from CB2. Charles Matthews (talk) 08:04, 8 September 2014 (UTC)

That's really interesting, Charles. However, I apologise that I've just realised that London Open House falls on the same day and I'll be in London for it. Would you be willing to lead the group in Cambridge? The group can also see the Riverside Bridge, swift tower and Logan Meadow LNR en route. How about meeting at The Haymakers pub which is served by the Citi 2 bus? cmɢʟeeτaʟκ 13:14, 8 September 2014 (UTC)

OK, I need to research some more. Thanks for the suggestions. Charles Matthews (talk) 08:29, 10 September 2014 (UTC)

Took some photos of Chesterton Tower... cmɢʟeeτaʟκ 23:12, 18 September 2014 (UTC)


Cambridge meetup and walk for 8 November[edit]

I'm thinking about a shorter walk for the Cambridge meetup. The theme would be Eglantyne Jebb: there is a plaque for her, but I had never noticed it. Charles Matthews (talk) 12:18, 3 November 2014 (UTC)

Thanks, Charles. I hadn't heard of Eglantyne Jebb before reading your note. I'd be glad to join your tour if you decide to run it as her biography sounds interesting. As I suggested at the last tour, do you think more people will come if we have it after the meetup? cmɢʟeeτaʟκ 13:59, 3 November 2014 (UTC)

Not in November, I think. I was intending to start at 1.30. Charles Matthews (talk) 16:47, 3 November 2014 (UTC)

Good point. Where does the tour visit, by the way? cmɢʟeeτaʟκ 20:53, 3 November 2014 (UTC)

Unfortunately I haven't had time to do preparation, since I have been working on quizzes over the past few days. The plaque is above Hockey's on Regent Street, and really not very obvious. I'd prefer to do that walk another time, therefore. Charles Matthews (talk) 10:38, 7 November 2014 (UTC)
