Could you explain why more than three primary colors are necessary to fill the whole human perceptual color space? Since our eyes only have receptors for three different wavelengths, it seems that we ought to be able to replicate any color with appropriate intensities at each of those three wavelengths.
Is the problem with current displays that they don't have exactly the right wavelengths, or is it something else?
Even worse is that in some markets, a station will be switching its DTV broadcasts to a channel that is currently in use for analog broadcasts by another station.
For example, in Detroit, Fox uses 2 for analog broadcasts, 58 for pre-transition digital, and will use 7 for post-transition digital. But ABC uses 7 for analog. So Fox can't switch unless ABC does so first.
Maybe channels that cutoff analog transmissions early should broadcast a DTV transition message on their analog channel for a week or two so people will know what's going on.
The 1,000 years isn't time from broadcasting to die-off. It is time from broadcasting to narrowcasting (using lasers or some other communications method that directly targets the intended receiver). Once narrowcasting is in use, we wouldn't expect to hear them unless they know we are here and are specifically targetting us.
I know you're joking, but apparently all that is needed for the Social Security agency to declare you dead is for a coroner to mistakenly type your SS#. From there it will get to your credit reports and pretty soon all your accounts will be frozen.
Here's someone who had it happen recently.
To be honest, I tend to worry a lot less about energy conservation in my home in the winter, since I've got a big machine in my basement dedicated to burning methane for the sole purpose of producing heat.

It's because we all disapprove of Congressional action in the abstract. Apparently most of us are quite satisfied with our own Senators and Representatives (just not all the others).:(
Cell phones, wi-fi, and cordless phones all work because they are heavily regulated. They follow FCC regulations about broadcast power, interference, etc.
If the radio spectrum were completely unregulated, Sprint could try to snatch AT&T's customers by setting up huge jamming stations in major cities. The broadcaster with the most power would win.
How did this get modded +5 insightful? If the publishers Google settled with had given Google the books and asked Google to scan them and put them online, then sued and gotten this settlement it would set that precedent. Somehow I doubt google would have settled with them in that case, though.
Re:Non-Tech Percent of Web Traffic from Chrome

On my non-techy website Logic Games Online, usage yesterday was 0.91% of traffic (and didn't start until 3:54pm EDT), and today it is 2.4% so far.
A good way to complement spam source filtering thru greylisting is to block home/dynamic IPs, ranges where mail servers arent supposed to be, but where are the majority of personal pcs (that gets owned by botnets). Spamhaus PBL i.e. have this particular target (or zen that combines this one with other known sources of spam)
Please don't. There is no reason that mail servers shouldn't exist on home/dynamic IP addresses. This is one area where I'm actually happy with my AT&T DSL service - they block outbound port 25 connections by default, but allow you to opt out of the blocking if you want to run your own mail server.
Savvy traders shun such stocks, but they are exactly what investors want. The stocks are in the indices precisely because they are relatively stable, established companies. Their movements reflect the broader movement of the market as a whole. If you want to make or lose a lot of money quickly, they are not what you want. On the other hand, if you want a consistent long-term return, you want stable, established, profitable businesses.
Well, if you could make a screen or paint that only reflects light at the frequencies of the RGB LEDs (for this projector) or lasers (for the PicoP) projector, you could get pretty decent contrast with not very many lumens.
But my doctor is licensed by the state. In fact, so are dentists, social workers, teachers, electricians, etc. Because of this, they need to uphold my trust, or they risk losing their licenses which means they are out of work.
I agree that global warming is often overhyped, but I think you may be overly discounting the negative possibilities / overly emphasizing the positive ones.
Global warming caused shoreline changes don't depend on how much temperature increases - they depend on how much land borne ice (as in much of Antarctica and all of Greenland) slides into the ocean. Note that the ice doesn't need to melt - ice melting in the top layer and the water subsequently melting through the glaciers to the land/ice boundary can lubricate a glacier and make it slide into the ocean, at which point it is causing water levels to rise, melted or not.
And, while increased CO2 will probably result in crops growing faster, I wouldn't be too confident about the benefits of increased rains. For one, much of that increased rain water gets into the atmosphere because evapotranspiration increases with temperature, so the soil and plants are constantly losing more water, and therefore needing more. In addition, increased rainfall likely means more heavy precipitation events, not many more gentle rains that crops like.
This is stated right on the registration page, "Not only will you be in your glory of coding, but there are prizes for it too! It's more than just $155,000 but a chance to work for the hottest tech company, Google."
Also, Google offered a series of interviews to all the finalists this year.
... but I don't think it brings anything much to the programming/computer science world.
I think it does bring something to the programming/computer science world, and that thing is press. If programming is shown in a fun and exciting light, it will encourage more people to pursue it.
My theory on why Poland has such a relatively high number of top programmers in these contests is that they get so much press in Poland. When a Polish programmer wins such a contest, there are front page articles in the newspapers. When Poland passed the US briefly in the TopCoder country rankings, there was an article about it in the Polish edition of PC World. All of this press gets other students to consider going into computer science.
It is mostly highschool aged students pushed by their respective schools so the school can get some local press.
First, you need to be at least 18 to compete.
Second, in this year's Google Code Jam, about half the finalists are students (grad or undergrad, though - not high school), and the other half are professional programmers.
There were 3 competitors from the US in the top 10 (4th, 5th, and 8th). Also, there were more coders from the US in the finals than from any other country.
I believe that Poland had the second largest contingent. Poland has been doing quite well in programming competitions, as the competitors there get press more like sports players do in the US, which attracts other talented people to the field.

Why this link is't published to start with is beyond me.
I think it is pretty obvious why the ad-filled link was published. Note that the article is from ComputerWorld, and the submitter was bsk_cw.If just the police were commonly trusted.
And any sufficiently advanced malice is indistinguishable from incompetence.
Verizon didn't need to keep bidding - they could have let Google have it at their last bid price.
Wouldn't the nano-scale features in the metal wear off the first time it goes through a carwash?
