The average galaxy experiences a supernova roughly once every hundred years. Yes, we have seen some; there was one in a neighboring galaxy in 1987. What's really whack is that there are about 100 billion galaxies in the observable universe. Using the estimate of one supernova per galaxy per century, this works out to like thirty supernova every second! Shit's blowin' up like crazy!

So they're wasting time on configuration options that I can (and do) change myself, instead of getting back on track toward their stated goal of producing a distro that "just works." Warty was a major breakthrough in usability, but it's only been downhill from there.

Comment tetrachromaticity (Score 1) 511

When people have less than three sensitivity peaks in their photoreceptors, we call them "color-blind" – a condition that disproportionately affects males. When they have more than three sensitivity peaks, we call them tetrachromats. Though not proven to exist, experimental evidence suggests they do. And the theory explaining their existence requires that they be female.

My understanding is that the RGB standard is the best compromise for the largest number of viewers. Sure, a fourth channel would probably improve the image for some viewers, but not all viewers. And it's not even clear that the same fourth channel would be the optimal improvement for any large subset of viewers capable of perceiving it.

Comment Re:It works for printers (Score 1) 511

The additional cartridges in photo printers are not different colors; they're different densities. Fine variations in print density can be achieved with the "thinner" inks, and the "thicker" inks can be applied for high density without saturating the paper (in the wetness sense, not the color sense).

Comment What the shuttle can do that Orion can't... (Score 2, Interesting) 234

The reason the shuttle is strapped onto the side of its launch stack is because it carries its payload internally. There are only two justifications for the engineering difficulties and operational hazards of this design. One is to have the expensive SSMEs attached to a recoverable part of the vehicle. The other is to give the vehicle the ability to recover payloads from orbit (read: steal enemy spy satellites.) With the end of the shuttle program looming, I'm guessing the Air Force is interested in maintaining that capability. And who knows... maybe they'll be nice and bring back Hubble, too.
