Color Spaces:
It has been known for some time that colors can be described by three numbers. If I show you light of a certain color and ask you to match it by combining lights of three other colors and varying their intensities, you'll typically be able to find a combination that looks indistinguishable. But the wavelengths you combine might be very different from the wavelengths I showed you. Light of the wavelength corresponding to yellow and light of the right combination of red and green wavelengths will look the same, even though they are physically quite different.

“Uncle Vincenzo,” implored the businessman, Angelo Salvatore, using a term of affection for the alleged head of Sicily’s Gimbellina crime family, 79-year-old Vincenzo Funari. According to a transcript of their wiretapped conversation, Salvatore continued: “For the love of our sons, renewable energy is important. . . .
It’s a business we can live on.”

As if a line like "their house is a museum, when people come to see 'em, they really are a scree-am" (heard, of course, in
the Addams Family theme) wasn't playfully brilliant (and brilliantly playful) enough, the same fellow happened to also have written
the Green Acres theme. If you're an American of a certain age, you'll remember these two songs from their original TV runs during your childhood, or perhaps from reruns if you're a bit younger. Anyway, the composer of these catchy, familiar ditties was one
Vic Mizzy. Hear Vic talk about the Addams Family theme and his degree in advanced finger snapping
here. Thanks Vic!

Apple is abandoning EPEAT Apple’s mobile design direction is in conflict with the intended direction of the standard. Specifically, the standard lays out particular requirements for product “disassemble-ability,” a very important consideration for recycling: “External enclosures, chassis, and electronic subassemblies shall be removable with commonly available tools or by hand.” Electronics recyclers need to take out hazardous components such as batteries before sending computers through their shredders, because batteries can catch fire when punctured.

The most common references you will see about the Green Swizzle, are the recipe that incorporates creme de menthe, or the quote from "The Rummy Affair of Old Biffy". It has been said, many times, that the creme de menthe version is not the original recipe and that the original "has been lost in history" or that "it never existed". These two statements I do not agree with, and I've managed to dig up a number of articles that prove the Green Swizzle did exist, and that the original recipe may be right in front of our eyes.

Solyndra used to make thin-film solar cells, but they could not make any money. The Department of Energy tried to help with a $535 million “Green” loan guarantee but the DOE missed the memo that says
EBITDA needs to be in the black if they expect to keep taxpayers out of the red. Private investors kicked in another
$70 million eventually but only after the DOE
primed itself. As White House economic advisor
Larry Summers noted, “…[government] is
a crappy vc [venture capitalist]…" Thanks to the DOE though, 40 employees and 150 contractors got to keep their jobs for an extra week last year according to the
WaPo.

In 1985, just a few months before its lamentedly-unsuccessful-yet-enduringly-wonderful big screen cousin was released, the
Clue VCR Mystery Game was released on an unsuspecting (and largely unwilling [some might say clueless]) public. The hugely-quotable and charmingly goofy VHS film included as part of the game is viewable in its entirety online in seven parts:
1 2 3 4 5 6 7. (If you must see the butler, Didit, explaining the rules, please use
these links in place of 1 and 2 above.) [Total video time: under one hour] Before you view [more inside] play a round of personal facts, followed by a round of cards.

Around
one year ago we saw some of the recent events in solar power. At that time solar panels topped out at a peak efficiency of around 290W for a 1.99 x 0.99 meter 72-cell module, with a lone rare and expensive
315W module that was used to build team Germany's
solar decathlon winning house. Since then prices have dropped a lot, and China is advancing in commodity tech.
