here are filter gels you can put over any illumination source -- they show a spectral curve for transmission for each of the filter gels The idea is to block the range around 450-500nm, the blue-green, that affects the receptors controlling melatonin.
Craig at LEDMuseum used his spectrometer on his fluorescent-backlit screen; here’s the results;
f.lux removes enough to change the color balance, but doesn’t zero out the band that affects melatonin (in fact doesn’t reduce it anywhere near as much as the “low blue light” compact fluorescents he tested for me years ago– that spectrum is also on his site, listed in the other info I’ve posted).
I’ll keep using f.lux — because it makes the screen less bright. I do like having that happen at night! but I’m keeping the yellow Rosco film for night use as well.

[QUOTE=The_LED_Museum]Good afternoon Hank,
I was able to shield the spectrometer from ambient radiation, and have obtained the following spectra:
[img]http://ledmuseum.candlepower.us/30/asusfw.gif[/img] Without F.Lux. Color temperature 6500K.
[img]http://ledmuseum.candlepower.us/30/asusflux.gif[/img] With F.Lux (color temperature set to coolest temperature {least blue display}). Color temperature 3400K.
As you can see, F.Lux doesn’t get rid of all the blue wavelengths — it only removes some of them. But this is on an Asus VW246H 24 LCD flat-panel monitor, which I believe uses a fluorescent backlightother monitors may “lose” more of their blue light component when this program is used on them.
for covering existing lights, you can use the yellow polycarbonate drinking water bottles from Walgreen’s, etc (don’t let them overheat, though).
For covering lights AND computer screens (and flashlights) you can get Rosco theatrical gel filters at any good photo or theater lighting supplier, for about $7 for a 20×24 piece. Deal!
This is “Daffodil”

That blocks most light below about 470nm (though you’d want to add their ultraviolet blocking filter as well, for any fluorescent light)

Yep. I use a tool for the Palm OS 5 PDAs that does brightness control excellently, down to a bare glow entirely adequate for reading with dark-adapted eyes.
Combined that with Mobipocket Reader's ability to choose a dark background and a yellow font -- and lo, no sleep problems at all.
Of course those aren't currently available, they're history.
Because you won't keep buying crap if you start falling asleep over the screen now will you?
Wake up! Click icons! Spend money! Choose any walled garden you like, just make sure you're inside the walls.
"'General Purpose Computer" sounds so militaristic, doesn't it? You wouldn't want civilians to get their hands on those. Might be dangerous to the economy.
I am really hoping that once Voyager gets outside the local sun's bubble, it picks up a dial tone.
After all, what makes more sense than modulating the background, and talking only to species smart enough to pick it up, by getting outside their local bubble?
My guess is most species would have been a little slower to send a probe out that far, and grown up a bit more in the meantime.

So what can targeted ads do that good search indexing and online catalogs and reviews can't do? They're for pushing stuff to people -- so they'll see stuff that they didn't decide to go look for or a search engine didn't show them from its own search results. How much value is there -- and who gets that value -- from doing targeted ads -- more than the value of providing on request good opt-in advertising? Tell us what it's worth?

Yup.
When general purpose computers are outlawed, business as usual can get back to normal.

But maybe.
It's been done before, accidentally:

Yep, that's right. Slashdot was refusing to post -- "nonstandard characters" that I couldn't find, so I ended up deleting the detail about the AR4.
