In one sense, this is a small thing. Still, I'm proud to contribute to Wikipedia, monetarily and editorially.
I've contributed to Wikipedia almost 100 times since 2005; I'm RedKnight7 there. Most of my edits are small, but I had fun with a few:
- I added 3400 characters to the Erath, Louisiana page on Henry Hub.
Natural gas prices in the U.S. are largely set at this important junction. I came across it looking into a business I'd like to start. I wondered who "Henry" was. Is it a first name? Last name? Not a name at all? I couldn't find anything on it - nor could anyone except the few who knew, I imagine - so I did internet and email research a few weeks, then shared it with everyone.
It was much more of a write-up than anyone needed, laugh. But it showed I had covered all the bases. You don't know if you have the full story unless you push it until you see that that's about all there is to say or find.
- I snuck in a scan of a telegram announcing my birth to relatives. Historical aid or historic cheekiness? You decide.
- An update on the history of Rabaul, a WW2 Japanese island fortress that the Allies went around and did not fully subdue until long after WW2. Wow, history is so full of amazing things. Update.
- I wonder what acronyms and other things mean; how can you leave obviously-specific names unexplained? Examples:
- What does the "YUV" mean in name of the YUV color-space image model ... yellow and ultraviolet? With the help of a video expert, I contributed:
- As for etymology, Y, Y', U, and V are not abbreviations. The use of the letter Y for luminance can be traced back to the choice of X Y Z primaries. This lends itself naturally to the usage of the same letter in luma (Y'), which approximates a perceptually uniform correlate of luminance. Likewise, U and V were chosen to differentiate the U and V axes from those in other spaces, such as the x and y chromaticity space. See the equations below or compare the historical development of the math. <plus three highly technical citations>
- Here's a fail (which makes it another example of why I wanted my own site):
- I helpfully pointed out that the odd-looking "nginx" (the name of some web server software) is just shorthand for "engine x". But a follow-up editor apparently did not know what i.e. (id est) means so he replaced it with "pronounced", then another objected to having two "pronounced" in one phrase, and wiped it all. And so ended the brief life of my helpful little addition.
- That's some real keystone cop action there, yet typical of public wikis. Sometimes it makes me wonder.
