It's a better way to make a big pipe, but it doesn't do anything for switching and routing.
Of course it does. Data in our current infrastructure is already multiplexed using packets. Sooner or later that multiplexed data is going to go to other locations. This is where your packet switch come to play. Until this time there wasn't a switch fast enough to handle this level of multiplexing. This is because current switches use old fashioned electronics to do the switching. By developing a photon based switch they hope to reduce or eliminate the switching as the bottleneck.
Please note: networks and optics are not my areas of expertise. Please forgive me for any mistakes I have made.
Why not try voting for Bob Barr, instead? Even if he doesn't win but gets over 5% of the vote, the next Libertarian candidate will qualify for Federal funds.
The conspiracy theorist in me noticed the timing of Jesse Jackson's comments about Obama. I'm wondering if it's an attempt to obscure Obama's vote in the media. Bill Clinton was accused of doing the same thing with the Monica Lewinsky scandal and Kosovo. I noticed the Jesse Jackson comment has gotten much more main stream press than Obama's vote.
(takes tinfoil hat off)
I'm still voting for Obama though. Stupid two party system.
Upload and edit photos from your hard drive, camera or MP3 player in 16 different file types, including JPEG, GIF, TIFF and RAW
I know for sure MP3 and JPEG aren't free. However, I believe the free version of Ubuntu ships with JPEG support. It also mentions "your...MP3 player" and not "plays MP3s". I'm not about to spend $20 to find out.
The CD audio standard is technically owned by Phillips. I'm guessing the patents ran out. But I remember having to install some sort of restricted software for CD's back in the day.
P.S. how is pointing out my one error more insightful than my previous comment? I gave up being a moderator on this discussion to make that comment. (the "Post Anonymously" system appears to have issues)
Ubuntu may be free, but MP3, CD, WMA, and MPEG playback aren't. The $20 is likely used to appease the "owners" of those formats. This is probably what they mean by "Complete Edition." We have been spoiled by how easy it is to install restricted software in Ubuntu. Some people may care about having all of their software legit.
this was mostly misreported by news agencies. They made it sound like nobody could build solar power plants, when it only applied to "federally managed land."
I agree. I use 768kbps at home. It's fast enough. I don't really notice a difference between it and the T line at work. But it's miles away from dial-up. I think most of the people in TFA aren't aware that they can get 768kbps for less than dial-up in most areas.
it's hard to argue that they should pay $50 a month for broadband.
Where do you live? Here in Illinois, these users qualify for AT&T's $10 program. I only pay $20 a month for cable internet (bundled with $40 basic cable). Those options are cheaper than some dial-ups.
This makes sense to accountants and CEOs. Believe it or not, when a company purchases a copy Office it goes into the asset pile. The asset pile means that the copy of Office has some sort of value. While it has value to the company, it does not have a market value. This is because that copy of Office cannot be easily sold. It's market value essentially goes to zero immediately after it's bought.
By renting Office, the bean counters can get the copies of Office out of the asset pile and put it into the expense pile. Even better, should the company require cutbacks, it can reduce the number of subscriptions (probably with a reduction of staff), to "save money."
It doesn't actually save money, but to people outside the company, people on Wall Street, it appears that way.
Here they are proposing to capture the compression heat and use it (with an "adiabatic generator"), which should help the efficiency. I'm a bit surprised the energy savings are worth enough to cover the capital costs of tapping such a low grade heat source, especially since this is also excess energy that will also need to be stored for later.
As I understand it, they plan to store the heat energy separately, and as heat. I suppose it would be like a big thermos. When they release the compressed air they heat it with this stored heat before it goes to the engine.
Heating very dense air is more effective at increasing pressure than heating less dense air. The fact that the air is very dense allows them to take advantage of this "low grade heat." It's all ideal gas law stuff. It's also why turbochargers are more effective when they have intercoolers.

How can a first post be modded redundant?
P.S. TFA is Slashdotted
No one could need more than 640 K of Memory
This article (pdf) has a good explanation of what I think they are aiming for. It even explains why it will be error free.

Because of the Nader thing back in 2000.

The paper showed up. Apparently it makes use of the Kerr effect. I'm speculating that it's more specifically kerr-lens modelocking.

professional poker is a psychological game. Unless the computer has the feeling of anxiety it will have an edge.
What I find impressive is the fact it lost in the past. It would also be interesting to see what it can do with some sort of lie detector software.
The hot female EE you speak of is a mythical creature, like bigfoot, or a unicorn.
Oh, they exist, I've seen them with my own eyes. They've just been hunted to the edge of extinction.
Yeah, but those hippie chicks are so fit from eating vegan food and walking everywhere.
I suspect if oil was found on BLM land there would be a cry for getting guvamint(sic) out of the land business.
Yeah, because there's no controversy over drilling on federal land.

My thoughts exactly! AOL is more expensive than most broadband options in my area.
I live in a rural part of VA that will probably not see wired broadband of any type for 20 years.
But only 14% of the respondents noted their rural location as being a factor.
it's hard to argue that they should pay $50 a month for broadband.

if a peer cannot share files with another peer?
People will stop using it once they realize it hogs their bandwidth.

will it still be after you compress the air?
They plan to heat the air before they let it expand. It allows them to extract more energy.
Here they are proposing to capture the compression heat and use it (with an "adiabatic generator"), which should help the efficiency. I'm a bit surprised the energy savings are worth enough to cover the capital costs of tapping such a low grade heat source, especially since this is also excess energy that will also need to be stored for later.
