WikiProject Computer science[edit]

As you may have noticed, Computer Science articles on Wikipedia are noticeably disorganized and of wildly varying quality, especially when compared to the quality of the mathematics articles. In an effort to address these problems, a couple of us are trying to revitalize the (apparently defunct) Wikipedia:WikiProject Computer science, and see if we can't replicate the success of Wikipedia:WikiProject Mathematics. We could use all the help we can get, so please stop by the project page and sign on as a participant if you are interested in helping out. Note that we're hoping this project will provide a good forum for coordinating the development of (and soliciting help on) articles in areas such as Formal specification, Design by contract, and other aspects of CS that I know you're interested in. We'd definitely like to get your input in these areas. --Allan McInnes 20:53, 26 January 2006 (UTC)[reply]

Algorithm guidelines[edit]

Hi Leland. What you proposed at Wikipedia talk:Manual of Style (mathematics)#Typesetting Algorithms is fine with me. I'm sorry for again assuming that you might not be aware on the ins and outs of Wikipedia, but you shouldn't be concerned with the lack of people yelling "Great idea!". People usually only point out the parts they disagree with. Please go ahead and add a section to the Manual of Style.

Hope to see you around, Jitse Niesen (talk) 15:04, 31 January 2006 (UTC)[reply]

Auckland meetup[edit]

Just to let you know that a meetup is planned in Auckland for the 25th of June (see Wikipedia:Meetup/Auckland for more details), and that you are cordially invited. GeorgeStepanek\^talk 00:21, 30 April 2006 (UTC)[reply]

Sunspot Number Image[edit]

Your Image:Sunspot-number.png is slightly flawed: you don't use the same vertical scale on all three rows. This makes comparisons between rows difficult. Do you think you could fix it? --TimLambert 13:23, 8 June 2006 (UTC)[reply]

I wrote this on the global warming talk page..... I guess I'm more likely to get a response if I write here....? :)Leland, look at the graph you included. Sunspot activity rises before temp and co2. The program discussed whether there was a delay in rising sunspot activity and rising temperatures. There may be a few years before the temp of the earth reacts to the increased activity, they pointed at the oceans taking a long time to warm and cool. Also, if you look at your own graph, temperature rises before CO2 levels rise during the last 40 years or so. Maybe temp rises result in more co2 being released by natural means?

Hi there, could you please update this image (http://en.wikipedia.org/wiki/File:Carbon14-sunspot.svg) with latest data? Thank you, Martin (9-JAN-2010). —Preceding unsigned comment added by 91.127.150.70 (talk) 16:05, 9 January 2010 (UTC)[reply]

grip vs ngrip[edit]

Thanks for some interesting graphs and great that you link the source data. It would be good if you add the value of the offset you applied.

One point you may like to comment on, that stp file you link apparently derives from several physical samples so I'm not sure how accurate your label GRIP is. It also seems to include that NGRIP data to which you compare it.

Oxygen isotope and palaeotemperature records from six Greenland ice-core stations: Camp Century, Dye-3, GRIP, GISP2, Renland and NorthGRIP

Graph on The Great Global Warming Swindle page[edit]

Hi Leland. Thanks for your work on that graph, it's very interesting. Is there any chance you could add the second version of the TGGWS graph to your combined graph? I think it would be helpful to readers' understanding (see TGGWS talk page). Thanks, merlin --Merlinme 21:23, 19 March 2007 (UTC)[reply]

Leland, I wanted to express my thanks for your hard work and valuable contribution with this graph and the others that you have done. This high quality of contribution is what makes Wikipedia a valuable resource for so many. ~ Rameses 14:42, 25 March 2007 (UTC)[reply]

Hi Leland! I wanted to ask whether you object transfering this image to Commons, so that other language versions of Wikipedia can make use of it? If you don't mind, I could do that since I'm working on the German article about TGGWS these days and find your graph very useful. Hardern 12:51, 3 April 2007 (UTC)[reply]

I have no problem with this. -- Leland McInnes 18:40, 3 April 2007 (UTC)[reply]

Carbon14-sunspot.svg[edit]

Image:Carbon14-sunspot.svg is perhaps open to misinterpretatation: Image:Solar variation and global warming.gif appears to make the obvious mistake, and (I think) has shifted the "solar data" by 50 years, though I'm not sure. Can you clarify? It was used on Solar variation but I'm going to remove it William M. Connolley 14:06, 26 March 2007 (UTC)[reply]

Yes, they are using the 14C timescale which, as noted in the description for Image:Carbon14-sunspot.svg, lags 60 years behind changes in solar activity. A further point is that 14C records past 1950 or so are very unreliable because of nuclear testing, thus you should be using direct data (i.e. sunspot number) rather than proxy data for anything covering the secnd half of this century. -- Leland McInnes 15:59, 26 March 2007 (UTC)[reply]

Your blog[edit]

is really interesting and I am going to read it all. I think that you must have read Gödel, Escher, Bach. --Blue Tie 05:23, 15 April 2007 (UTC)[reply]

Thank you for the kind words. I have indeed read Gödel, Escher, Bach, among many other books on similar subjects. My goal is to eventually write my own book on these sorts of topics. -- Leland McInnes 06:40, 15 April 2007 (UTC)[reply]

I like reading such things. Related to our discussion about science, I read a book some years ago from Plenum Press called The Art of Mathematics. I found some errors in it and discussed them with the author and was going to give him a list to fix, but I never got a round2it. But I like some of what he had to say. Among other things he suggested that the paradigm of looking at the math content in a field of study would indicate the degree that it was "scientific", with Theoretical Physics being the most scientific and "Sociology" being the least scientific of the sciences.

If your blog is going to be your book, I guess I wont have to buy it when it comes out. heh heh. --Blue Tie 06:55, 15 April 2007 (UTC)[reply]

Mathematics CotW[edit]

Hey Leland, I am writing you to let you know that the Mathematics Collaboration of the week(soon to "of the month") is getting an overhaul of sorts and I would encourage you to participate in whatever way you can, i.e. nominate an article, contribute to an article, or sign up to be part of the project. Any help would be greatly appreciated, thanks--Cronholm144 23:06, 13 May 2007 (UTC)[reply]

svg[edit]

Hey Leland, do you mind if I svg-ify your cross and triple product images?--Cronholm¹⁴⁴ 15:57, 19 July 2007 (UTC)[reply]

If you can make them render properly, then by all means. The SVG source should be included on the image pages in question. -- Leland McInnes 16:06, 19 July 2007 (UTC)[reply]

Oh... I didn't realize they were already svg based(I just see png and jump)... I have devised a rather inelegant solution to the rendering problem. But it takes time and is rather tedious. I might still convert them, but definitely not today. I will do my homework next time before hopping to a talkpage. Cheers --Cronholm¹⁴⁴ 16:14, 19 July 2007 (UTC)[reply]

HadCrut graph[edit]

Hi Leland! There is some discussion about your version of the temperature plot here. Would you mind commenting? I don't have numpy installed (my setup of Python on the Mac is via the Fink, so the standard distribution is not helpful), so I cannot run your program. But it seems that there is a problem at the extreme boundaries. Thanks! --Stephan Schulz (talk) 15:44, 18 January 2009 (UTC)[reply]

Dating and format of graphs[edit]

Thanks to all who put such time and effort into creating the graphs which add so much visual information to raw data!

If I could make one suggestion however, it would be to make some note on the graph as to the latest date the data covers or has been updated. Naming the origin of a graph with "0" or "Present" soon becomes outdated in rapidly changing situations such as climate. If one element such as CO2 has been updated, then temperature should be updated as well. Might I also suggest making graphs available in PDF format since pdf images can be expanded to nearly any extent that the underlying data will support and any increment in between.--Tobyw (talk) 17:28, 19 March 2009 (UTC)[reply]

Temp-sunspot-co2.svg[edit]

Hi Leland, would you please include the data sources for the image Temp-sunspot-co2.svg you uploaded? (I.e. give credit to who did the measurements and/or data processing.) Thanks. JBatista 08:41, 24 August 2009 (UTC)[reply]

Apparently the data sources got hidden when someone shifted the image to commons; I've reinstated the relevant material. -- Leland McInnes (talk) 20:26, 28 August 2009 (UTC)[reply]

Updated Python script for image on commons[edit]

Hey, I've been learning Python, so I used your image as my first experience fixing something. The image was moved to Wikmedia Commons by a bot, and since the time you made it one of the data pages was taken down so obviously Python's urllib.urlopen was getting a 404. I changed the link and rewrote some more of the script such that it reproduces your graph on my computer. You may want to test and check to see if my changes are kosher. -Theanphibian ^{(talk • contribs)} 00:49, 22 October 2009 (UTC)[reply]

NowCommons: File:Instrumental Temperature Record by R Rhode.svg[edit]

File:Instrumental Temperature Record by R Rhode.svg is now available on Wikimedia Commons as Commons:File:Instrumental Temperature Record by R Rhode.svg. This is a repository of free media that can be used on all Wikimedia wikis. The image will be deleted from Wikipedia, but this doesn't mean it can't be used anymore. You can embed an image uploaded to Commons like you would an image uploaded to Wikipedia, in this case: [[File:Instrumental Temperature Record by R Rhode.svg]]. Note that this is an automated message to inform you about the move. This bot did not copy the image itself. --Erwin85Bot (talk) 08:32, 7 October 2009 (UTC)[reply]

Would like permission for one of your figures to be included in a science journal[edit]

C14 data graph.[edit]

Hi Leland, You got a very interesting GFDL graph, where you plot the historical C14 data against time. I tried to understand how you got to this graph from the source data. Can you comment on this? I plotted the source data and it looks similar but the graph is not even surjective, While your graph is surjective. How do you correct this function? Thanks. — Preceding unsigned comment added by Laurensdelange (talk • contribs) 22:14, 1 April 2011 (UTC)[reply]

Surjective on what range? Which C14 plot? I'll presume this is April fools related and moved on. -- Leland McInnes (talk) 03:04, 3 April 2011 (UTC)[reply]

I am sorry, I made a mistake and plotted the uncalibrated Before Present BP.

This gave me this strange graph.

IPCC radiative forcing diagram typo[edit]

Your excellent diagram, which is used all over wikipedia, has a typo. NO2 should read N2O. I notice that the German version is correct!

I Believe I found another (small) mistake. The unit on the Y axis is (W/m)2. It should be (W/m2). I guess the "2" got caught on the wrong side of the paragraph.

Regards, Jannikkappel (talk) 08:18, 15 September 2011 (UTC)[reply]

I just notices that the two flaws have already been corrected in the graphics if I download them, however the visible one in the articles, eg. http://en.wikipedia.org/wiki/Radiative_forcing contains the flawed graphics. Jannikkappel (talk) 08:27, 15 September 2011 (UTC)[reply]

Hi, pretty graphic. A couple of things:

The source reference (RS) has been deleted (can't be found at ucar.edu) and the official IPCC's working paper summary for policy makers page 16 doesn't talk at all about this data. The closest graph that I can find is the Third Assessment report graph. Can you correct the reference so we know where the data is coming from?
The third and fourth assessments talk about LOSU (Level of Scientific Understanding) regarding each forcing but your graph doesn't include that very important data but the Third Assessment graphic does and without it, it appears to the reader that we're dealing with absolutes, which we are not. I'm happy to update but need to know your sources (third assessment or fourth assessment) so it's consistent.

I'll watch this page for your thoughts. Thank you Just Anonymous 17:05, 9 July 2012 (UTC)[reply]

File:Sunspot-temperature-10000yr.svg[edit]

Hi Leland,

Could you clarify how you produced the temperature line in this graph from the EPICA data? If I plot the data it looks nothing like your graph. I'm probably missing something simple... 217.121.218.160 (talk) 17:19, 6 November 2011 (UTC)[reply]
