unfortunately not quite so easy, as there is more that the video card needs to do other than rasterisation (ie, drawing scanlines). There are many other tasks including edge clipping, face culling, etc which are slightly more difficult to split the load between graphics cards.
I'm not sure exactly how well this is achieved in SLI but I'm sure there isn't a perfect 50/50 split, and there won't be a doubling of performance. I'm sure it's close though
no need to give them local access to your system, they can easily read it if you have an ssh server set up for example. And no it doesn't display the root password, but it displays a username/password combination which has access to sudo. So just as bad.
Well done for Opera passing the ACID2 test, although it's no longer a useful test for browser standards adherance. The best test was how versions of each browser released BEFORE the ACID2 test rendered it, so this race for "ACID2 Adherence" is useless. Who passes first isn't important, as they're only fixing a tiny subset of the entire standard. It no longer shows who is more standards compliant.
as an analogy, if you surveyed 100 employees of Google and found they were being paid less than 100 employees of Microsoft, and Google countered by giving those 100 employees a raise, it wouldn't change the original issue. The ACID2 test is simply a "survey" of web standards.
well that's ok, because the study was about Electromagnetic fields, not magnetic fields, which are two different things. As far as I am aware, there is absolutely no danger to humans from a magnetic field.
that is completely different. There's an issue if you want to keep your kid away from black people but there's no issue if you want to keep your kid away from racists. Honestly, your argument is ridiculous. Parents have a right to look after their kids. If they don't want them to play games in an environment where profanity is usual then fine. Hopefully then we will end up with less people who can't say a sentence without the word "fuck".
if you don't want your kids growing up with black people then you have some racial issues. Just because the same argument can be made about black people doesn't mean that the guy is being unreasonable about parents wanting to keep their kids away from cussing
us Aussies are professionals at disowning people who embarrass us. Russel Crowe (Kiwi) Mel Gibson (Does anyone want him?). I'm sure this guy will be next.
I'm on the Hurstbridge line and we get some great graffiti too (our trains also smell like piss). it's always such a shame when someone puts a giant tag over a nice piece of artwork. I see signs everywhere saying "Tagging is illegal" but I don't see anywhere "Graffiti is illegal". Interesting.
I actually like the fact that they spend time cleaning the walls that are covered in graffiti. I take the train every day and it gives me some fresh graffiti to look at. And clears of the ugly black tags.
Although Connex could certainly do with spending their money elsewhere.
That's what special about geosynchronous orbit. Orbital velocity is slow enough that I can use the Earth's rotation to supply it.
it appears to me that you hold the belief that if you go straight up from the Earth, you'll keep rotating in line with the point you launched from on the surface.
This is wrong. Ever hear of the Coriolis effect? You must have heard of it. Basically if you throw a ball vertially up high enough, it will end up landing west of where you threw it from, because the Earth rotates underneath the ball. It doesn't "keep in step with the Earth" as you seem to think. Therefore we cannot simply launch a sattelite straight up and assume that the Earth's rotation will give it the velocity it needs in order to get into a geostationary object. It still needs to be accellerated quite a bit (460m/s to 3 km/s), because it's further out and needs to travel further.
99.99999% of the atmosphere is below the highest X-15 plane flight on August 22, 1963 which reached an altitude of 354,300 ft or 108 km.
big difference to 62,000 km. however, I will concede that you did say "pretty much" do that. However, they cannot completely leave the atmosphere, as rockets can
simply by building our velocity high enough to escape velocity while in the atmosphere and letting inertia take us out.
Ignoring that whole "air resistance" and "speed of sound" thing.
if you get high enough in our atmosphere, there's less air to resist. The idea of escape velocity is if you reach 11.3km/s on the surface of the Earth you will keep going forever, provided that there is no retarding force (ie. ignoring Air Resistance). however, taking air resistance into account, you can STILL escape with a single push, you just need to go a lot faster (and have a very streamlined aircraft). This is of course simpler when you're higher upThat was the point I was trying to make.
I get velocity from the Earth all the time. It's called standing on the ground.
Funnily enough, this is NOT a geosynchronous orbit, which is what I was talking about.
That's what special about geosynchronous orbit. Orbital velocity is slow enough that I can use the Earth's rotation to supply it.
At Geosynchronous orbit you need to get about 36,000 km above the surface of the earth at a velocity of about 3 km/s. On the surface we revolve at about 0.46 km/s. I don't know what velocity you are getting from where, but it takes quite a lot of work to get a sattelite up to geosynchronous orbit and also accellerate it to the point of having it stay in orbit.
the ONLY special thing about a geosynchronous orbit is the geostationary orbit, whereby you can have an object in geosynchronous orbit above the equator, and it will stay in the same position relative to an observer on the Earth's surface.
It's not "negligible" - it's two thousand miles an hour (curiously, roughly 1 km/s). It's just neglible in the rotating frame of the Earth
ok, my apologies. I used the wrong word here. At this height, you have a lower escape velocity, you also have a much lower accelleration due to gravity. The escape velocity doesn't matter, in this case, because you don't really have much force pulling you back, you only need a small force to accellerate away from the Earth. This makes space travel very cheap from 62,000 miles
ermmm... here in Australia we all know about cane toads. It's pretty much common knowledge that the cane toads brought in were a complete failure, they never even ate the damn beetles they were supposed to. They've been causing issues for decades, and we all know what a problem this has caused, probably since about five years after they were introduced. I'm pretty sure this is common knowledge in America too (after all, it was in a Simpsons episode).
The article submitter and the moderator must know absolutely nothing about Australia to have come up with such a terrible summary. I almost laughed at Yahoo news for posting this until I read the parent post
Also, the cane toads were brought in from South America, not Hawaii
wow, I've never seen a score 5 post with so many completely wrong comments in it.
Planes and Balloons can't get above the atmosphere, because they both need an atmosphere in order to work. Jet engines need some sort of air around them in order to generate push and lift. Balloons rely on the air inside them being lighter than the air outside them. No air outside means no lift. We use rockets because they are the only way of truly leaving Earth's atmosphere. They are also the only way we can get out of the influence of Earth's gravity. If our atmosphere extended much higher, in theory, we could take a plane to the moon, simply by building our velocity high enough to escape velocity while in the atmosphere and letting inertia take us out. However, the jet plane is bounded by the atmosphere, because it needs atmosphere to move.
Geosynchronous orbit means that it orbits with a period of exactly 24 hours. There's nothing "special" about Geosynchronous orbit which means you can "get the velocity from the Earth". You DO have velocity. From an observer on Earth, it would look like you're standing still, but it still takes a lot of energy to get there. Once in orbit, of course, it doesn't require energy, but NOTHING in orbit requires energy
The idea of a long cable is not to get us out of the atmosphere, but to get us far away from the pull of Earth's gravity. If you climbed all the way to the end of the cable and let go, given you had escape velocity, you would get past anywhere. The idea is at that height, escape velocity is negligable. The idea is it takes little effort to leave Earth's Gravity at that height
I'm getting sick of this comment. have you actually tested it or are you just regurgitating what all the other people are saying?
Try using Firefox 1.5.0.1 and load up a whole bunch of tabs, and then close them. Watch the memory usage drop.It doesn't drop all the way back to where it was, but it gets most of the way there
oh no! you mean that a company based OUTSIDE the US can now become successful internationaly? STOP EVERYTHING! This law is stopping the US stranglehold on the world's market! We can't have a chinese startup becoming a big player in Search, they have to be AMERICAN companies!

for those people there will always be the blu-ray release of The Matrix: Reloaded
thankyou for giving me a slightly more understandable version of events.
however, I don't think we're passing through Earth's magnetic field at faster than 0.2c, so surely this doesn't make a difference?
yeah, I could spout a bunch of made up drivel here too to support what I said.
look, if you can't write something that makes sense or link to a site that does, I'm not interested.
well that's ok, because the study was about Electromagnetic fields, not magnetic fields, which are two different things. As far as I am aware, there is absolutely no danger to humans from a magnetic field.
Ahhh whoops sorry, I forgot I was posting on /. here. I'd better get back in line with the geek stereotype.

that's "there's no giant pole for geosynchronous orbits"
ok, now I'm confused. I thought we were talking about geosyncronous orbits, not the space elevator. There's no giant pole for the space elevator.
Anyway, as far as I understood, it was a giant Ribbon, not a giant pole. I am quite sure a pole 62,000 miles long would be quite bendy
It's ok, you can keep him
funny, isn't the Nintendo DS outselling the Sony PSP?
But the PSP is more powerful! The graphics look better! and all nintendo has is a puppy sim!
You're right, my girlfriend is being annoying and reading over my shoulder and asked 'what is a rootkit?'
