Gnomes are stealing articles from my watchlist [1]. If you respond to me on a discussion page there is a chance I won't see it, since they ate that particular article and it is not on my watchlist anymore. So if I don't respond, put a note on my talk page.
Is it just me, or is it getting more vandalous in here? It is hard to keep track of all these anons...
I love Wikipedia.
I am an electronics/DSP engineer working in the field of pro audio equipment. I also enjoy music; listening (experimental electronic, metal, indie rock or whatever), creation (computer synthesis/recording, homemade electric violin), and performing. Articles I contribute to will probably be related to these things.
I am also working on the Electronics wikibook, if slowly.
I read an article somewhere that convinced me that most Latin or foreign phrases really have no use in English, and just alienate certain classes of people, and I have been casually changing them into English equivalents when I run across them. I wish I could find the article...
The rest of this page is just notes to myself, basically.
Don't defend your beliefs. Test them.

Electronics diagrams
I have been making electronics diagrams using klunky schematic editor, and modifying and annotating the screen shots in paint shop. I convert them to 2-color (they are originally JPEGs with several shades of white) and save them as PNG, with transparent backgrounds. They tend to be very small (~1 KB). I have been using Arial size 10 for labels, bolded for titles, but I may switch to Tahoma since it has a nicer I and is a bit easier to read. I welcome requests and suggestions.
See Omegatron/Gallery.
Modified version of Klunky
I have made a modified version of Klunky, reducing the file sizes of the images and adding a bunch more images, such as batteries and voltmeters, etc. Also it just runs a lot faster if you have it on your own machine. It is available for download from http://mysite.verizon.net/negatron/klunky.zip Just unzip to a directory and open klunky.html. The author of the original said effectively that it was open-source, though I wasn't able to actually get a reply from him about the modification. If you know javascript and want to make it work in more browsers, that would be helpful...
Forced PNG rendering
I figured out a way to force PNG rendering of TeX markup, as it was needed on the resistor page. It is possible to force the formula to render as PNG, without affecting the display of the formula, by adding \, (small space) at the end of the formula (where it is not rendered). This will force PNG if the user is in "HTML if simple" mode, but not for "HTML if possible" mode (math rendering settings in Preferences).
You can also use \,\! (small space and negative space, which cancel out) anywhere inside the math tags. This does force PNG in "HTML if possible" mode, unlike \,.
This could be useful to keep the rendering of formulae in a proof consistent, for example, or to fix formulae that render incorrectly in HTML (at one time, a^{2+2} rendered with an extra underscore), or to demonstrate how something is rendered when it would normally show up as HTML.
For instance:
| Syntax | How it looks rendered |
|---|---|
| a^{2+2} | <math>a^{2+2}<math> |
| a^{2\,\!+2} renders the same | <math>a^{2\,\!+2}<math> |
| a^{2+2} \, renders the same | <math>a^{2+2} \,<math> |
| a^{2\,+2} is bad | <math>a^{2\,+2}<math> |
| \int_{-N}^{N} e^x\, dx | <math>\int_{-N}^{N} e^x\, dx<math> |
| \int_{-N}^{N} e^x\, dx \, | <math>\int_{-N}^{N} e^x\, dx \,<math> |
| \int_{-N}^{N} e^x\, dx \,\! | <math>\int_{-N}^{N} e^x\, dx \,\!<math> |
| \,\!\int_{-\,\!\,\!\,\!N}^{N} \,\!\,\!\,\!e\,\!^x\,\!\, dx \,\! | <math> \,\!\int_{-\,\!\,\!\,\!N}^{N} \,\!\,\!\,\!e\,\!^x\,\!\, dx \,\! <math> |
You might want to include a comment in the HTML so people don't "correct" the formula by removing it:
- <!-- The \,\! is to keep the formula rendered as PNG instead of HTML. Please don't remove it.-->
Spell checker
I've experimentally started spell checking entire articles occasionally with the Spellbound extension in Firefox. I have both the American English and British English dictionaries, and if there are words from both I use whichever is the majority for consistency. ("Note that the English form of Wikipedia has no preference for American, British or other forms of English so long as this is consistent for the whole page.") Occasionally it "corrects" a word wrongly and I miss it. Sorry.
