It also depends upon the definition of "first contact". Physical contact with an intelligent alien species that has traveled to earth? Communications with an extraterrestrial species? Discovery of any form of extraterrestrial life? I'd need to know the specifics before I'd put money on either side of that bet...
And regarding SETI@home, the SETI Institute or the staff members thereof, I don't speak for them, although I understand many are environmentally conscious.
Environmental irresponsibility has always been considered a possible solution to the Fermi paradox. I wonder if civilizations have died out because they didn't like the way energy efficient light bulbs looked? Probably not, but when you add in all the other annoyances energy efficiency can cause...
So in a ideal capitalist society, a person would be encouraged to save everyone a million man-hours because if he made something that useful he'd become rich.
No. In an ideal capitalist society someone else would come along and sell a nearly identical solution for less.
We know mercury is bad. The article you referenced assumed people recycle the bulbs.
Go back and read it... The mercury released my a coal fired power plant lighting a 75 watt bulb (for a median CFL lifetime) is more than the mercury contained in a 75 watt equivalent CFL. Even if you throw the CFL bulbs in a landfill, less mercury is released into the environment (and in a less toxic form) than would be for incandescent lighting, even when you consider than only 50% of US power comes from coal.
So I hope you'll excuse me if I return the favor to you. Since you are getting such exceptional lifespans from your light bulbs it would seem you have new wiring and likely a newer home. You've helped contribute to urban sprawl by buying a new house instead of an existing house an performing upgrades as I did. Hence you're likely living on land that was recently in a natural state until it was developed into another cookie cutter suburbia.
I live in a home build in 1956 with no wiring upgrades since then, although I have replaced the ceiling light fixtures in two rooms. It is in suburbia, because I could not afford a home or rent in the urban setting near where I work. Either option would double my housing cost.
I contribute to global warming and air pollution by car pooling to and from work in my Prius four days a week. (20% reduction in fuel use at the price of 10+ hour days). Tell me about your SUV and how safe it is.
We heat with natural gas, but plan to convert to a heat pump system when we can afford it. We also plan to add solar panels to the roof, again when we can afford it.
We've done something more to save the earth for future generations. We didn't have any resource hogging children.
A mass is an energy and vice versa. A wavelength is not a frequency, nor is there a constant relation between them They are not equivalents. There is no analogy to anyone that comprehends math and physics.
Or retards that can't see that 1055 nm doesn't have units compatible with frequency. A change of one word (frequency to wavelength) makes it correct. 0.0009478 nm^-1 could work, but that's not a frequency, it's a wave number.
Just because something is convertible doesn't make it a proper measuring unit for the quantity being stated. If you start giving "frequencies" in eV, m^2 or dyne second/gram (all of which could be converted) people are going to think you're an idiot and, in the sciences, they certainly won't respect your work.
Walk up to someone and tell them how fast your car goes in GHz^2 by dividing the distance traveled in "GHz" (which is equivalent to a distance according to you) by the time it took in nanoseconds. People will think you're a retard for giving them a meaningless number that was calculated incorrectly.
It doesn't matter whether the virtual particle falling into the hole is a particle or an antiparticle. (In fact most will probably be photons which are their own antiparticle). The only thing that matters is that the escaping particle has energy. That energy had to come from somewhere. That somewhere would be the black hole itself.
However, here at most times, 100 watt hours coming from my central (natural gas) furnace is far less expensive than 100 watt hours in electricity to light a light bulb. The only type of central heating that light bulbs are competitive with (in terms of cost) is electrical resistive heating. Oil, gas, wood, heat pump/geothermal are all less expensive. It's also less efficient overall, because of losses between the electrical generating station and the home.
It derives from the right of the governed not to be raped by people who think their 'freedom' includes the 'freedom' to destroy the lives and livelihoods of others in order to make a buck.
What's sad is that the newer incandescents may only use 25% of the energy but the laws are based on the technology- not on the energy consumption and they ignore the mercury poisoning aspects.
Lie repeated often are still lies. The law in this case is based upon watts per lumen. If there were incandescents that used 25% of the energy, they would be legal. Also the mercury released to the environment from an incandescent is worse than the exposure from a CFL.
You've forgotten this is slashdot. A large number of readers here need to turn a light on and off ten times then turn around three times while tapping their head before they can enter or leave a room.
No. I don't think that's true. I think that if saving the planet would inconvenience you or take 30 seconds out of your day, you'd rather someone else did it.
I change a light bulb about every 3 months. I have 25 bulbs in the house, so that's an average lifetime of 75 months or 6.25 years. Since they aren't on continuously that's probably below the advertised lifetime. But I'm OK with that.
And feel free to worry about mercury from CFLs while ignoring the mercury that power plans are pumping into the air.
the current generation of Core2 arch and ix arch from Intel/AMD/IBM are virtually impossible to make into a rad hardened build.
That depends upon where you are going and how much weight you can carry. For a relatively benign environment like low earth orbit which usually has lots of weight margin you can always add shielding. Not that I would choose them for a design... The issue there is that they are more complicated than necessary for what needs to be done. Never use a 16-bit processor when an 8 bit processor will do the job. For an spacecraft onboard computer, I would probably choose ARM, MIPS, or PPC.
I'm pretty sure that zooming the flash along with the lens was already being done on P&S cameras back in the 90s. Is this a case of tagging "on a telephone" to an existing patent?
It sounds like the light they see is monochromatic. Hawking radiation would be blackbody radiation. Unless they have a reason why this blackbody would only have one mode and an incredibly high effective temperature. I'm guessing that they've found an uninteresting fluorescence feature.
Technology review's arXiv blog is so difficult to get any details out of. It's hard to figure out what these people have done. "frequency of 1055 nm"? I guess I'll have to go to the full article.

Judges can order that a corporation be dissolved for misconduct.
And the last time that happened to a large corporation is....
I'd be pretty pissed if I bought a backlight utility and found out it was dialing home. Remind me to never purchase an app from this crew.
Well, developers could put their apps in one of the non-Google operated android markets.
Cumbersome checkout function? Isn't the second purchase one click more than installing a free app? Or are you reentering everything every time?
It would cost me more than $1.99 to figure out how to pirate this app.
I think you've got it backwards. If it were a sure thing it would pay 9000% interest. (A 1 dollar bet pays 100 dollars if aliens land).

I wasn't demeaning your children. It's not like they had a choice in the matter.
Yep, the truth is always a troll. Government enforced monopolies are not a necessary part of capitalism.
