Intro

I really don't know that there is anything important enough to put here, but it's in the user space so I'll do it...but just for the following reason:


My favorite color is blue ...hmmm...doesn't sound like a reason, until you realize that creating this page changes links to my user name from red to blue.


Date of my first edit: 26 NOV 2004


Really, Really Important things I've learned about Wikipedia

These are my notes:

Write to the target audience

    • Audience: A related question, is who should the pages be written for? Most writers are in college or past college. However, there is evidence that most readers are high-school students, or other people who are not familar with a topic. What is obvious and irrelevant to a CS student or grad, may be very unclear and important to a high-school student or someone who is thinking of returning to college. Of course, Wikipedia has yet to define its target audience very well. The lists make it accessible to a much broader audience. excerpted from a comment by an anon who signed his message: The Phantom Avenger for SE


Summary:

    • K.I.S.S. - Keep It Sweet and Simple.
    • Write first for the Educated Layperson (that's hard)...
    • ...then try to do it better and write for the beginner (that's harder)
  • If an educated layperson can't figure it out by following the wikilinks, then it's too hard.
  • Yes, we're experts (more or less) but we're writing for a general audience. We could write a clever, concise, deep sentence to explain something...but it's useless if it isn't easy to understand.
  • Eschew argot, technicality and cant.


Spelling/Grammar checking

'Whenever doing anything but minor editing, copy and paste to a word-processor with real time spelling/grammar checking!

That and that I can't spell. I also can't capitalize, but that's a different matter.

Stub Sorting

I'm part of the stub sorting project. We're trying to sort stub articles into more focused categories so people with special interests can more easily find articles to expand.

My response to being informed (after sorting hundreds of stubs) that there were estimated to be 20,000 stub articles to sort was:

whimper...whimper...whimper...

Fortunately, we seem to have gotten a handle on the number of articles left in category:stubs to be sorted. More will gradually migrate in (as they are edited for other purposes and the category is updated) but at a more-or-less managable rate.

I hope this project proves useful.


Cleanup Projects

We seem to have briefly caught up with stub sorting so I think I'll spend some time working on:

Category:Cleanup by month
Category:All articles needing copy edit --> Wikipedia:WikiProject_League_of_Copyeditors/proofreading#Ready_for_final_proofread
Category:Articles that need to be wikified
Wikipedia:Deadend pages (a lot of these are pretty easy since they are actually stubs that need to be wikify-ed).
category:Category needed (maybe someday, when I catch up...)
Wikipedia:Uncategorized pages
m:Transwiki transwiki instructions
Wikipedia:Peer review

Stubs I should be able to contribute to

Category:Connecticut geography stubs
Category:Computer stubs
Category:Inorganic compound stubs

To Do

I made admin

We all know admin is "no big deal" (in fact the quote is here, Jimbo Wales said it), but it's really nice to be asked.

The vote is/was at Wikipedia:Requests for adminship/RJFJR. (I put this link here so I could watch while I was fretting over whether I'd get it).

here is the admin's reading list that I'm still trying to absorb and will keep handy as a reference.

Spelling

Turns out these need to be done periodically:

  • resevoir -> reservoir
  • tendancy -> tendency
  • seperate -> separate
  • foriegn -> foreign
  • sportscar -> sports car
  • diminuitive -> diminutive

Words I'm suspicious of

I am suspicious of the word whereby. It's a real word, but I want to take a look at articles that use it and make sure they are clearly worded.


Images

Press Releases

This is a question I posted at Village pump (Policy) and the replies. I am placing it here so I don't forget it.

Celesio was begun with press-release. Is it correct that a press release is not copyrighted? RJFJR 15:56, Jun 26, 2005 (UTC)

In the United States, everything is copyrighted. --Carnildo 20:39, 26 Jun 2005 (UTC)
But if it's a press release being sent out to be published, aren't they granting rights to reproduce on it? Or does that just apply to people they directly send it to? RJFJR 20:55, Jun 26, 2005 (UTC)
That may be (or may not be). IANAL. But I assure you, that press release is not under the GFDL. --Carnildo 21:09, 26 Jun 2005 (UTC)
Press releases are definitely copyrighted. They do not grant free rights to reproduction — they license it for reproduction to certain partners under certain conditions, in the same way that a record company licenses its music to the companies that print the CDs and gives people who buy the CDs very limited personal use rights. I am not a lawyer, however. Deco 21:01, 26 Jun 2005 (UTC)
I'm not a lawyer, but I am a journalist. "License" at least implies more formality than exists. Maurreen 21:15, 26 Jun 2005 (UTC)
Thank you, everbody! I have chopped, added an external link to the press release, and marked corp-stub. (I will file this as a reminder. I appreciate it). RJFJR 01:35, Jun 27, 2005 (UTC)






Footnotes

For more details on this topic, see Wikipedia:Footnotes.

A footnote is a note placed at the bottom of a page of a document to comment on a part of the main text, or to provide a reference for it, or both. The connection between the relevant text and its footnote is indicated by a number or symbol which appears both after the relevant text and before the footnote.

  1. Place a <ref> ... </ref> where you want a footnote reference number to appear in an article—type the text of the note between the ref tags.
  2. Place the <references/> tag in a "Notes" or "References" section near the end of the article—the list of notes will be generated here.

Example:

According to scientists, the Sun is pretty big,<ref>Miller, E: "The Sun.", page 23. Academic Press, 2005</ref>
however the moon is not so big.<ref>Smith, R: "Size of the Moon", ''Scientific American'', 46(78):46</ref>

== Notes ==
<references/>

Result:

According to scientists, the Sun is pretty big,[1] however the moon is not so big.[2]

Footnotes come after punctuation

Footnotes at the end of a sentence or phrase are placed immediately after the punctuation. For example: President Bush called for a halt to the violence,[3] and opposed a timetable for withdrawal.[4]

What footnotes are normally used for

  • Some publications use footnotes for both the full citation of a source, and for additional comments or information of interest to the reader.
  • Some publications use Harvard style notation for sources, and use footnotes exclusively for tangential comments or more detailed information. In this case, in other words, footnotes are notes with relevant text that would distract from the main point if embedded in the main text, yet are helpful in explaining a point in greater detail. Such footnotes can be especially helpful for later fact-checkers, to ensure that the article text is well-supported. Thus, using footnotes to provide useful clarifying information outside the main point is fine where this is needed.

Determinining the coefficients

Draft

The following explains how to find the determine the coefficients of the fourier series that corresponds to a function, if the fourier series exists.

To determine the coefficients an and bn one relies on a property of sines and cosines called orthonormality which reduces this to solving an integral that may be simple in many cases.

\int_{-\pi}^{\pi} \sin(nx) \sin(mx)\, dx = 1\text{ if }n=m\text{ and }0\text{ otherwise}
\int_{-\pi}^{\pi} \cos(nx) \cos(mx)\, dx = 1\text{ if }n=m\text{ and }0\text{ otherwise}
\int_{-\pi}^{\pi} \sin(nx) \cos(mx)\, dx = 0

A special case applies when n = 0

\int_{-\pi}^{\pi} \sin(0 \, x) \, dx = 0
\int_{-\pi}^{\pi} \cos(0 \, x) \, dx = 1


Assume there exist coefficients an and bn such that

f(x) = \frac{a_0}{2} +\sum_{n=1}^{\infty}[a_n \cos(nx) + b_n \sin(nx)].

Then

\int_{-\pi}^{\pi} \left( \frac{a_0}{2} +\sum_{n=1}^{\infty}[a_n \cos(nx) + b_n \sin(nx)] \right) \sin(mx)\, dx = \int_{-\pi}^{\pi} \left( \frac{a_0}{2} \sin(nx) +\sum_{n=1}^{\infty}[a_n \cos(nx)\sin(nx) + b_n \sin(nx)\sin(mx)] \right) \, dx = \int_{-\pi}^{\pi} \frac{a_0}{2} \sin(mx) \, dx + \sum_{n=1}^{\infty} \int_{-\pi}^{\pi} a_n \cos(nx)\sin(mx) \, dx + \sum_{n=1}^{\infty} \int_{-\pi}^{\pi} a_n \sin(nx)\sin(mx) \, dx = \int_{-\pi}^{\pi} b_m \sin(mx)\sin(mx) \, dx = b_m.

and

\int_{-\pi}^{\pi} \left( \frac{a_0}{2} +\sum_{n=1}^{\infty}[a_n \cos(nx) + b_n \sin(nx)] \right) \cos(mx)\, dx = \int_{-\pi}^{\pi} \left( \frac{a_0}{2} \cos(nx) +\sum_{n=1}^{\infty}[a_n \cos(nx)\cos(nx) + b_n \sin(nx)\cos(mx)] \right) \, dx = \int_{-\pi}^{\pi} \frac{a_0}{2} \cos(mx) \, dx + \sum_{n=1}^{\infty} \int_{-\pi}^{\pi} a_n \cos(nx)\cos(mx) \, dx + \sum_{n=1}^{\infty} \int_{-\pi}^{\pi} a_n \sin(nx)\cos(mx) \, dx = \int_{-\pi}^{\pi} a_m \cos(mx)\cos(mx) \, dx = a_m.


Since we already assumed they were equal we can substitute ƒ(x) for the fourier sum we are seeking and thus

\int_{-\pi}^{\pi} f(x) \sin(nx)\ dx = b_n
\int_{-\pi}^{\pi} f(x) \cos(nx)\ dx = a_n

provided that the Fourier series converges and thus exists.
