Hi, feel free to leave me a message. Kindly leave messages on new topics at the bottom of this page. Srleffler
Hi Srleffler! I just wanted to stop by and wish you a Merry Christmas. I very much appreciate all you do for Wikipedia, and for the help you've given me alike. You're the first person I think of if I have any question relating to optics, light or lasers, so I thank you for all of your assistance. I hope you have a very good Christmas and may the New Year be filled with joy. (The happiness, not the dish soap.) Zaereth (talk) 02:00, 21 December 2013 (UTC)
Happy new year!
- Thanks. Happy New Year to you too. I replied in that discussion.--Srleffler (talk) 03:09, 3 January 2014 (UTC)
Correct me if I am wrong but simple past tense is used when something either happened in one moment in the past or was true in the past but no longer is. For example: "My father was alive back then" means "he no longer is". Similarly, "The shell of Windows 1.0 was a program known as the MS-DOS Executive" means it no longer is.
Second, "Windows 1.0 no longer exists" needs a source. Well, don't bother; it still exists.
Last but not least, I am surprised how an experienced editor like you does not stick to WP:BRD. You do know that responding a revert with another revert is either edit warring or leads to one, don't you?
- When discussing historical subjects, one typically discusses them in the past tense. Windows 1.0 is no longer in use, anywhere. I don't doubt that there are hobbyists who maintain old hardware on which they can still run it. I don't think that is relevant.
- The mixture of past and present tenses in those sections of the article doesn't scan well. It's cleaner to let history be history and discuss it in the past tense.
- You're correct that my second revert was poor manners. Sorry about that.--Srleffler (talk) 04:47, 2 April 2014 (UTC)
- Hi again.
- Windows 1.0 is not historical yet. 25 years is hardly history. But, embedded devices used in factories still use DOS and Windows 1.0 (or other old version of Windows.) These machines can work for centuries with zero need to update their software, as long as their moving parts are kept in maintenance. I am often asked to add new 64 KB templates to their memory banks for production.
- But we even had a village pump discussion of whether to use past tense or not. The issue of the mixture of tense came up. (I'll hunt the diffs for you. But I distinctly remember using a "married woman" example.) The consensus was that software logic must be written in present tense; and the issue of odd looking mixture is a late warning that article is written badly, so that historic subjects and descriptive prose are separated well. (Against I distinctly remember trying to establish a guideline with others when someone cut me short and said "TL;DR. Guideline: Write well.")
- Hi. Sorry to keep you waiting but retracing my steps have proven to be a little difficult because Editor Interaction Analyzer and Revision History Search are down at this time. (Searching the village pump archive brings up a lot of results.)
- I restored two non-tense related changes that appear to have been swept up in your revert. I don't think they will be controversial.--Srleffler (talk) 04:53, 2 April 2014 (UTC)
Question to your note
Hi Srleffler, at first: thank you for your help at my articles. My second question refers to my article about "fiber optic nano temperature sensor" (https://en.wikipedia.org/wiki/Fiber_optic_nano_temperature_sensor). I'm inexperienced with wikipedia and i understand your problem only partially. Maybe you can help me to solve it? What can i do to avoid a deletion of this article?
- I'm happy to help, but unfortunately the deletion proposal already went through and the article has been deleted. The process works this way: an editor puts a "proposed deletion" tag on an article, with an explanation of why they feel the article should be deleted. Anyone else, including the creator of the article, can dispute the proposal—ideally by fixing the problem. If no one does this within a week, an administrator will delete the article. This is one of several methods of deleting an article on Wikipedia—there is also a more formal process for debating cases where there are different opinions on an article, and a "speedy" process for dealing with obvious problem articles.
- I proposed deletion because it appeared that the article covered a single company's product. That seemed like much too narrow a scope for a Wikipedia article. It also violates some rules. By policy, Wikipedia cannot be used for advertising. We do sometimes write articles about companies and their products, but to include such an article the organization has to be notable. Coverage of all topics on Wikipedia must be neutral. Editors are strongly discouraged from editing articles on which they have a conflict of interest. If you work for a company or otherwise have a financial or personal interest in one, you should not be editing articles about that company or their products.
- If you don't have a conflict of interest on this topic, I recommend you look for a suitable article in which to include a brief mention of this technology—perhaps Fiber optic sensor and/or Thermometer. Keep in mind that coverage of a topic must not be given undue weight. This is not a very important technology within the broader topics of fiber optic sensors or themometry, so it wouldn't merit more than a sentence or two in either of those articles. --Srleffler (talk) 04:50, 8 April 2014 (UTC)
Hi, I noted you've been active on the candela talk page. I noted an example in the article is incorrect, perhaps you'd like to check and verify. https://en.wikipedia.org/wiki/Talk:Candela 22.214.171.124 (talk) 10:13, 27 April 2014 (UTC)
Thank you for the time you give to the Wikipedia. As you probably remember, I have tried twice to put, on Wiki-english, external links towards my programms, which are to be downloaded from a site (a google site: https://sites.google.com/site/elearningclassicalphysics/optique with the comment: Simulations of the main interferometer devices. University Paris XI ). You tell me that there are possible problems with viruses: if not now, in the future. So, I do not understand how an executable (a .jar) could make problems with viruses, but I am not an expert in viruses (I use a Norton antivirus and that is enough for me) and I listen to what you say. But could you tell me how my simulations could be seen, using an external link in Wikipedia, without downloading the program into the reader's hard disk? Formerly the google sites allowed direct executions of programs copied in there, but no longer, as far as I know; I have now to copy the program into the google site, and this copy is the one which is proposed for downloading to the reader of Wikipedia; I have tried another site (not google site), with the same result. My programs are .jar's, this means executables made in Java. The solutions with Applets are not so safe as with jar files, and also not so handy. Also, I have remarked, in the "Michelson Interferometer" page of Wikipedia that the link of University of Porto, namely: http://fisica.fe.up.pt/michelson/index.html resulted into ... a downloding of a program from their site (may be done in another way?). Finally, I have french versions of my .jar's, which I have put on Wiki-french, in the same way as I did with your Wiki-english, without any problem.
Could you please, make to me a suggestion so that I could execute my programs from Wiki-english. Thank you very much in advance and best regards. Truocled.
- The best solution would be to have your code execute as an applet within an HTML page. This is more secure, since web browsers execute applets in a "sandbox", which is supposed to limit the program's access to the client computer. Downloading an executable file is more dangerous. I have less of a problem with the University of Porto page, precisely because it is hosted by the University. I hope that the University exerts some control over the material on their website, and will ensure that it is and remains free of viruses and malware. An independent personal website can never offer any confidence in that regard, since the site and its content can change with the whim of the site's owner, or could become infected with viruses through that individual's negligence.--Srleffler (talk) 19:00, 27 April 2014 (UTC)
Hi, Mr Srleffler. I have looked at the solutions to execute a .jar executable without having to download it. The solution with applets seems difficult, as I found on some forums claims that Java was not always supported by sites, and I would not like much to go into that direction. But I found that it was my navigator (Firefox namely) which constrained me to download the .jar. If I take Chrome, or Internet explorer, I simply put the address of the .jar into the address bar (for instance, https://sites.google.com/site/essaispourapplets/home/applis/en_application_chaine.jar, you might try it) and you may run it without downloading it: for Internet Explorer, a box proposes to download or execute (without downloading), for Chrome, there is a proposition on the bottom left to download, but if you click on the element, you execute it without any download. This procedure might be explained to readers of my site. The only point is that, right now, I do not understand why Firefox does not propose to execute without downloading; I have looked at Java plugins, found one which was "blocked" for "savety reasons", eliminated it and reinstalled Java7, ...., but I did not make any real progress. Another point is that you do not really know who I am, and especially if I am really from the University Paris XI (in fact I retired in 2004). If you ask me, I could produce for you the proofs that I was working in a physics collaboration in Hamburg (Germany), and gave lectures at Orsay, nea Paris. If neccessary, I could ask my former laboratory, the so called "Laboratoire de l'accélérateur linéaire" (LAL) to host my programms. Friendly Truocled (talk) 15:14, 10 May 2014 (UTC)
- I tried the URL above. It doesn't seem to work—nothing there. I assume that Firefox blocks executing your jars because it is not a safe thing to do. It is never possible to execute the code without downloading it. What matters is whether the code is run in a "sandbox" where its access to the computer is limited, or if it runs as an application with free access to the system. I know that applets run in a sandbox. I don't know whether the other options do this, or whether they allow unrestricted access to the user's computer.
- My concern isn't so much about who you are, but about the way the files are hosted. I'm willing to assume that a major university hosting material on its site has the measures in place to ensure that the programs are free of malware, and that they stay that way. Another issue which I should have brought up here is conflict of interest. We generally prefer that people not insert links to their own material into Wikipedia. Put your material up online, and if it is good eventually maybe someone will link to it.--Srleffler (talk) 17:58, 10 May 2014 (UTC)
Apologizes: The link is https://sites.google.com/site/essaispourapplets/home/applis/application_chaine.jar !!! (application_chaine.jar and not en_application_chaine.jar, the "en_" being for "english"). I just verified it.
You say: "It is never possible to execute the code without downloading it". It seems to me that it is not true: take the link above and put it on Internet Explorer, you are asked either to open, either do download. If you choose open, then there is execution, and, at the end of this execution, your file "downloads" is free from "application_chaine.jar"; but may be I do not understand everything. You say: "We generally prefer that people not insert links to their own material into Wikipedia." I understand that for articles, where there are possible discussions and contestations, but not for simulations which are illustrations, "experiments". The fact is that I have prepared simulations which are my "own material". Then I do not see how I could show this simulations through Wikipedia if this was a "conflict of interest"; may be it's impossible? If so, I do not insist.
I do not understand what you mean by "Put your material up online". It should visible on research motors, like the one of Google, is it what you mean? If so, it is "online". But it would be more visited if I could put it on Wikipedia. And simulations are meant to be looked at!
But I understand your concern about possible malware. It would be difficult for me to put my stuff on the site of mu University ParisXI, but it could be possible to join the people of the L.A.L. (laboratoire de l'accélérateur linéaire, Orsay), which is the main French Laboratory of high energy Physics, and to ask to them to host my .jar's. I would prefer not to do it, but if you say it is necessary, I could try. Truocled (talk) 20:18, 10 May 2014 (UTC)
I hope you don't mind me hitting you up for information on this. I know there's lots of info out there and I viewed Richard Feynman's lectures on reflection, but I still can't get into my mind a clear understanding, so I'm trying to take in as much info on the topic from as many sources as I can.
Regarding your note at: https://en.wikipedia.org/wiki/Talk:Specular_reflection#Unclear_information
"If you reflected a single photon off of the surface, I believe you would find that its angle of reflection is random, with probability distribution matching the intensity distribution for the reflection of a beam of light.--Srleffler (talk) 05:26, 2 January 2009 (UTC)
Would you say that this would be the case regardless of the surface. In other words, for either diffuse or specular reflection?
Also, if you have any explanations of your own, and\or other sources to point me to, expanding on how a result of angle of reflection = angle of incident comes about for many photons, though as you describe above for any given single photon, the reflecting angle is random (and there's just a probability that it will reflect at the angle of incident?)
Probability distribution matching intensity distribution: does that mean that the more photons incident at particular angle, the higher likelihood of reflecting at that angle?
- I think you've misunderstood. Yes, what I wrote is true for either diffuse or specular reflection, but for a specular surface the probability distribution is very narrow: if you have a single photon with a well-defined direction before it hits an ideal specular surface, it will reflect in the direction predicted by the Law of Reflection. If such a photon hits a diffuse surface, and you measure its direction afterward, you will find that it has reflected in some random direction, with the probability distribution being proportional to the intensity distribution you get if you shine a beam with many photons on that surface. There is nothing too surprising in this, and the quantum physics doesn't really add anything to the discussion. I mentioned it only because the person I was replying to asked about it.--Srleffler (talk) 05:27, 28 May 2014 (UTC)
Hello Srleffler, can provide a MOS quotation for the guideline you are refering to, please? Petr Matas 23:31, 14 July 2014 (UTC)
