I'd think that you would want a vehicle about the size of the space shuttle orbiter (109,000 kg loaded). so given:
E = 1/2 MV^2 The kinetic energy of something that massive moving at 10,000 m/s is 5,450,000,000,000 Joules. That would be a lot of juice. However, you wouldn't need it all at once since the acceleration would occur over about 69 seconds. Since 1 joule per second = 1 watt. 5,450,000,000,000 / 69 = 789,855,072,463 watts (790 gigawatts)
The largest power-plant in the world is the Three Gorges Damn in China with an estimated maximum output of around 22Gw.
The High Magnetic Field Laboratory Dresden at the Rossendorf Research Center has the worlds largest capacitor array which can store 50 megajoules and cost 10 million Euros .
So, unless we scale up nuclear power plants or create a capacitor array capable of storing 5.5 terawatts or reduce the size of the vehicle we're at least an order of magnitude off. But it still seems like it could work.
"Atmospheric and gravity drag associated with launch typically adds 1,500-2,000 m/s to the Delta-V launch vehicle required to reach normal LEO orbital velocity of around 7,800 m/s (17,448 mph)."
So lets assume 10,000 m/s because the atmosphere is so much denser near sea level. The sled would probably need more but that could be overcome with rockets on the sled itself which kick in after it leaves the track.
using v^2 = 2ax
yields a track length of 300.12km
I'm no rocket scientist but that seems possible to me.
To me, it looks like the robot is focused on keeping the acceleration due to gravity between the skis. I know it must be considering the centripetal force, Yet it does not seem capable of 'hanging it out there', in a turn steep enough to support an acc due to gravity that doesn't point between the skis. I think this is part of what's holding it back, and if so it would mean a snowboarding robot wouldn't work as well with the same tech.
oh man, what about looking at people on their webcam and using the text to speech tool to speak to them over their speakers. ahh the day's of windows 98.
all hardware will deffinetly have linux drivers. This alone alieviates so much trouble from when you have to patch the kernel and do wierd shit to get all your buttons working. don't even get me started on trying to get everything to work on my tablet.
hardware manufacturers who do bussiness with dell now have a valid bussiness-wise reason to make linux drivers.
other manufactureres are following suit and also offering home PC's and Laptops with Distributions.
I plan on getting one of the first laptops to ship with an Nvidia 8600 go chipset. I will probibly buy one of the desktops as well, just because I support what Dell is doing and I really want this to succeed.
I was under the impression that both analogies were pertaining to open-source development models.
the Cathedral represented the model where there were a just a few "wizards" who did the critical work. only open sourcing it after codifying developmental stages have been reached. an example of this model is how Novell built XGL. Keeping it under wraps then blowing everyone out of the water with it. Codifying the release to prevent premature forking.
Debian would be the best example of the Bazaar method. unfortunately the Debian bazaar is becoming more and more gridlocked.
you don't even have to claim it if you make less than $2000 off of it. And don't even try to come up with a retort because my brother works for the IRS.
yes but what they say and what they enforce are two different things. they make the laws out of catholic guilt. they can always look at playboy because they will be forgiven for it anyway.
sorry I have to agree here. debian is debian is debian. what you get for free is the best version of debian there is. with fedora or suse the users are broken up into first and second class citizens. I personally can't bear to install a "second class" OS.
indeed, I and many friends use slackware. slackware isn't as dependant on a community because most users don't bother with the package system. this way when you have a problem installing a tar, you can go straight to the project forum to figure out what's wrong and missing rather than dealing with a distro forum who probibly doesn't know jack about the software you're trying to install anyway.
I'm not terribly worried about piracy. most companys and bussinesses are too scared of getting in trouble to pirate software. and most of the people who pirate entertainment software woulden't buy them otherwise. besides in most games like quake the more people that have the game and the more open it is, the better the game gets through user created modifications, more people to play against, better competition. the list goes on and on. the bottom line in my opinion is people should try to find more creative ways to pay for the game. Like everquest, sure tons of people bought the game but the bulk of profit deffinetly came from the subscriptions. and just think of how many more people would have played the game if they gave it out for free.
I believe we should try to start a movement to use slowly transfer over to the myan calander. it is much more accurate and way more bad ass. this would also separate church and state that much more. (a problem where I am from (utah)).
I am a freshman studing computer science at the university of utah. I am planning on making games for linux once get out of collgege. would the indremea be a good start for me to practise making games on before I enter the real market? how difficult is programing for the indremia versus programing for a normal pc? will there be tutorials to help me program for it?

Right. But if you make the 'track' sufficiently long like I mentioned you could do it with 12gs.
I added to it on my post on reddit:

Looks right to me. This got me thinking about how long a 'track' would have to be to launch someone into space.
According to Wikipedia's article on g-force:
"Early experiments showed that untrained humans were able to tolerate 17 g eyeballs-in "
http://en.wikipedia.org/wiki/G-force
Eyeballs in means perpendicular to the spine such that the force pushes your eyes into your head.
and their article on Low Earth Orbit:
"Atmospheric and gravity drag associated with launch typically adds 1,500-2,000 m/s to the Delta-V launch vehicle required to reach normal LEO orbital velocity of around 7,800 m/s (17,448 mph)."
http://en.wikipedia.org/wiki/Low_Earth_orbit
So lets assume 10,000 m/s because the atmosphere is so much denser near sea level. The sled would probably need more but that could be overcome with rockets on the sled itself which kick in after it leaves the track.

you completely missed the point.

you guys are both being stupid.

3.9"?? that mobo couldn't satisfy even the geekiest nightelf.

where o where id my moderator points go. there should have gone here.

man you would have been so pwned right now if this were digg. -10,000 for fluffy karma fantasy-land

games and bitchin hardware are only useful until you get hooked on forums.

rather than paying that much for bandwidth I would rather just stay in my dorm with my flat 50 bucks a semester internet fee and get 10mbit+ a sec =]
