True story.
I used to be a resident advisor at UAH. One morning I woke up and tried to log on to Everquest. No workie. That's OK I thought, maybe an unscheduled patch... so I went to check some other stuff. It didn't work. AIM didn't work. This is all sounding a little fishy so I check my voicemail and sure enough, a bunch of my friends note that every game, filesharing and otherwise service is down, with exception of POP3 email and WWW. Couldn't even IMAP or FTP off-campus.
I brought this to the attention to the housing director, who knew nothing of any plans to alter the network. I knew one of the higher-ups in the network ladder, I talked to him but he was out of the loop. He set up a meeting with the appropriate people. I got there, along with the head of the housing department. Remember, we were represening a bunch of very pissed off college kids living on-campus. The guy blew us off, saying "school is about education" and "If my daughter lived on campus I wouldn't want her playing video games and downloading music." I countered by saying some of us come from thousands of miles away, and this is home, and we need to relax on the weekends when we aren't studying.
Long story short, we ran a petition drive, appealed to the president of the university, and after a few weeks of hard work and lobbying got ports back on a case-by-case basis, but they put in a load-balancing system and metered the filesharing ports to the point of being unusable.
From talking with colleagues from other schools, this seems to be a typical mindset of a University administrator. Good luck, Dell. It sounds like a good idea, but I think it will be a hard sale to make.

Now, well the terrorists are playing right into the hands of George Bush!
You mean... it shows he's right? There is a terrorist threat? He's not just a crazy republican? *sigh*
I think you will be suprised. G8 will do what its supposed to do. There will be some interruption - this is a major event - but I think overall a lot will be done. Don't discredit them over a single terrorist act.
Regardless of your opinions on the situation...
With the recent "discovery" of a statement where Bram "encourages" piracy. Coupled with the Grokster ruling. Coupled with how we all know the court systems can work... just imagine what happens if the courts go kung fu on BitTorrent's ass in the near future, and Opera has all these "BitTorrent clients" floating around the internet. Could get messy.

Also breaking the OEM and MSFT monopoly would have been a nice idea. So you would have to buy the 'expensive' software off the shelf. That might have made people think twice about buying it.
That'd kinda be like selling appliances without power cords. Make people decide what source of power they want. I mean people could choose - wall sockets, solar power, nuclear reactor in their basement, hampster wheel, whatever. But you'd probably wind up with a lot of people who'd fry themselves trying to attach the default power method anyways, just like you would probably wind up with a bunch of people buying Microsoft products anyways. It's just not worth the trouble.

But yea, IMO, the whole thing is rotten. The reason Go flopped wasnt because of MS, it was because pen-based computing wasn't popular back then. It really isn't all that popular now. I mean yea we have Palm Pilots and what not; but it looked like Go was aiming at the comptuer market anyways and not necessarily the portable market...

Because if he would have RTFA he would have realised the money generated from the auction was going not to line the pockets of George Lucas, but rather to preserve the rest of the props and other pieces of memoribilia from the original Star Wars movies. It's an independant project and they need funding to get it going.
And how the f*ck is an auction with a few props going to "rob you blind"? Don't go and don't bid if you aren't interested. That's why he's modded troll (And for once... good job mods)

His information isn't his. He ripped it from various forums like howardforums.com. I applied this method to my phone back in.... april. He should have at least acknowleged the source he got it from (the only links he provides are to places to get *software*).
Second off be careful: I would suggest researching this on Howardforums or another reputable cell site before doing it. See the process is derived from the v710 hack, and you want to make sure you are applying the right hack to your phone lest you break your phone. Messing up the seem is bad.

Think about it from the frame of reference of the sun. The earth is orbiting the earth. Now this little copper thing the size of an oil barrel (the impactor) and the satellite leave earth orbit **just barely** by increasing its velocity beyond the velocity of the earth. That is, escaping earth's gravitational well. From the point of view of the sun, the impactor and satellite are still orbiting it. It doesnt matter if it did complete an orbit. Unimpeded it would have.
Second point of view: the velocity of the impactor was less than the escape velocity required to escape orbit from the sun. Therefore it had to be orbiting the sun.
Not to mention, astrophysicists and rocket scientists will routinely refer to hyperbolic orbits as orbits, even though they will never complete a revolution. In fact, at infinite time they will approach 180 degrees. But it is perfectly acceptable to consider this an orbit. (consult Brown, "Elements of Spacecraft Design" or any orbital mechanics text)
Who gives a rip about answers.com... ask a real rocket scientist or astrophysicist. That's the problem with you whipersnappers nowadays...;)
...and don't watch it. Find your local comic book/Anime store and rent the series uncut. The amount of editing Cartoon Network would have to do for a daytime broadcast would not do the series justice.
Evangelion is truly one of those series that people either love or hate with a passion. (I happen to be in the love camp...)
You have to look at it the same way the rocket industry was built. Simplifying and omitting a lot, in the 1930's-40's the Germans built a series of short-range suborbital rockets with the intent of hitting London and other targets. America and Russia both get their hands on rocket scientists and hardware. America then plays with this technology for damn near 15 years before they send a human being up. That's quite a development cycle. Roughly 25 years. And there were people who experimented with rockets before then: Tsiolkovsky in Russia laid down the foundation for H2-O2 rockets in the early 1900's (the rocket science institute in Russia followed up on these ideas before the Germans); Hermann Oberth in Germany did work in parallel. Robert Goddard was experimenting in America. So a 25 year development cycle on a technology that had existed in smaller scale forms for a good 15-20 years in physical form and even longer on paper.
A new technology would presumably need a similar development cycle. Laser propulsion, space tethers, I'm not sure what you have in mind... needs to be tested on paper (in computer simulation) with realistic, feasible materials, then implemented on a non-human test scale, and then tested on a human scale with "test pilots." Then development of a commercial version can begin. Remember... we've been spacefaring for over 40 years now, and we still haven't commercialized it yet.
I am very sceptical that funding **every** X-project would get us any closer. A lot of X projects were funded. Most of them have to do with experimenting with aerodynamics and propulsion: that doesn't change the fact that we are still bound by the chemical energy available to us.
Nuclear propulsion is ready as soon as society says it is acceptable. Project Orion in the 1960's developed it, and was cancelled. There exist designs (indeed; Pratt and Whitney is ready to make a tri-mode nuclear engine called the Triton with Isp ranging from 300-900).
The difference is... Big Dumb Rockets exist, they work, and they get the job done. Everything else is speculation until they can prove that they too can get the job done. Designing a new space program around technology that is nothing more than speculation, is nothing more than stupid.
The problem with chemical propulsion is we are just on the cusp of being able to work it to get to space. If it were just a little less efficient, it wouldn't get us there no matter how much fuel you put in. If efficiency increased, our rockets would get much much smaller... but chemical energy is one of those things that are locked in to the nature of the chemical.
delta-V = 7600 m/s for LEO (a little more for space station)
g = 9.8 m/s^2 (gravity)
Isp = 295-450 1/s (Specific Impulse, basically a thrust rating of a propellant. 295 for a solid in a vacuum, 450 for a SSME in a vacuum. Lower on the surface of the earth)
m0 = takeoff mass
m1 = mass on orbit
Play around with the numbers. You will find out quickly that single stage to orbit with any significant amount of payload is... hard. And this doesn't include mass requirements for coming home: retro-rockets, wings and landing gear or parachutes and more rockets, etc.
Until some material advances are made (mass ratio, m1/m0 can be imrpoved) or nuclear propulsion can be considered an acceptable option (The technology exists: Isp = 800-900) single stage to orbit with any more than 1-3 human beings will be a difficult feat.
Staging alleviates the problem. Check out Sutton's Rocket Propulsion Elements or Hill & Peterson's Mechanics and Thermodynamics of Propulsion.
Re-using existing technology is the quickest, cheapest, easiest way to get back in business. I think it's a pretty good idea.
The vehicles being proposed do not at all resemble the shuttle. The shuttle itself is being scrapped. The solid rocket boosters, a modified external tank, and the Space Shuttle Main Engines (SSME's)
The key difference between the new models and the existing shuttle is serial architecture versus parallel architecture. The Space Shuttle is an example of parallel architecture - all of the stages firing together. The new proposals operate in serial, one stage at a time. That's a lot safer: abort modes are easier to implement. A first stage failure is not immediately a fatal incident. Also notice they are implementing the CEV for the crew module, not a shuttle.
And although the spaceref article and pretty pictures are new, the ideas/rumors have been floating around the Aerospace community for quite some time now.
But in all seriousness I think ESR has a point. Let me spin it from my point of view: RMS is very caught up in himself. RMS claims the GPL to be his own literary work. I don't see the same thing beind said about any other license. He has such a big head he should start selling real estate to astronomers or something. Maybe then SETI would find ET.
