To put it in simple non-technical terms, you can't slow down fast enough. Yes, you can get a good bit of speed up over several months on a more direct trajectory, but you'd end up having to start slowing down once you're only 1/2 way there.
To make it at all reasonable, you'd have to use a few gravity sling-shots to build up speed and possibly dump speed later. Once you're doing that, you might as well go with the old tried and true chemical propellent that gets you up to speed much quicker.
Ion drives are great if you're going to be going in a straight line for a very long time and don't want to stop, ever. The farther you go, the faster you go, so the less reasonable it is to slow down.
I have even read of deep-space solar-powered mission designs that head in inside mercurys orbit, grab loads of power and then head out beyond Jupiter..
Really? Where do they store all this power? If they used an ion drive, they would need constant power for the entire trip. Sounds a little fishy to me...
Great. Illinois, for the record, as the fifth largest state in the union, has a population of over 12M. The unemployment rate seems to be around 6%, which means probably thousands or even tens of thousands of people file for unemployment every month.
So, exactly how many of those out of work and possibly homeless people do you think own computers and pay monthly service fees for internet access? Perhaps the homeless connect through their cell phones?:P

Maybe the U.S. government is afraid of letting intelligent people who think the U.S. government is screwed up be left alone.
There's a difference between being intelligent related to government issues, and being an absolute conspiracy nutjob who people, apparently like you, think is intelligent about government instead of just being an autistic chess wiz who thinks the Jews made up the Holocaust to make money.
Perhaps we shouldn't put him in jail, but we should certainly lock him away somewhere.
The real point of this is to get people to go to the site, realize all the crap they are starting to publicly offer to spammers about you, and force everyone to purchase private registration.
Sounds like a good recipe for getting yourself shot by a police officer. Don't laugh, it almost happened to a friend of mine on Halloween when he pulled his laser tag gun, at night, on what he thought was another party-goer.
Exactly. I don't recall seeing people here up in arms about the still pending judge nominations that the Dems have been blocking for, what, years now... Ah, good old biased slashdot.
How typical of slashdot to make this sound like an Evil Republican Conspiracy(tm). I mean, after all it's all the rage to do that right? Of course, if you read the article you'd notice:
"The bill has powerful backers. Among the bill's co-sponsors are Senate Majority Leader Bill Frist, a Tennessee Republican, Senate Minority Leader Tom Daschle, a South Dakota Democrat and Judiciary Committee ranking Democrat Patrick Leahy from Vermont."
What's that? Democrats support it too?! *GASP*!? How about a little fairness in the submissions once in a while? I know a large portion of the slashdot crowd will just see the submission blurb and go off a vote Democrat, thinging the Democrats are all nice and tech friendly, and little do they know... *sigh*
Factual error: In the scene where Peter is saving the children from the burning building, there is no smoke from the fire. Black smoke would be bellowing out the windows. He wouldn't be able to just stand up and walk through the building.
OMFG A HOLLYWOOD MOVIE HAD AN INACCURATE PORTRAYAL OF A FIRE??? WHO WOULD HAVE EVER SEEN THAT COMING!
No kidding. As a firefighter myself, with how much free burning fire there was in that building there wouldn't be much smoke inside the building. It was all burning too cleanly. Of course, it would have to have been over at least 1200 degrees in there for that kind of fire to occur so he still would have been toast, but not because of evil black smoke(tm).
Or maybe not, apparently someone linked to the wrong company. Radarvision is an Aliens motion tracker, not sure about the device the article was actually mentioning.
The salient point (that you're ignoring) is that Bush remained in the photo-op, reading to the class, for something like ten minutes after he was informed that a massive terrorist attack was taking place in New York.
Give me a break, do you even know what happened that day?! When the first plane hit no one knew what the hell was going on, they thought it was an accident. They didn't know it was a terrorist attack! My god, TEN MINUTES? You mean, shorter than the time between the two planes? About the amount of time it would take a secrect service agent to find out information and decide to get the president the hell out of dodge? Give me a break, if you hate the man, say it, but don't make shit up. *sigh*
- Bush has received millions of dollars from the Saud family, this has resulted in unprecendented access.
I have no comment on this because I don't know if it's true.
- In August of 2001, Bush took a vacation when the threat was building.
Oh my god, a president went on vacation!? String him up! Do you realize that "the threat was building" during the entire Clinton administration? So I guess Clinton never took a vacation, otherwise Moore would have gone after him too, right? Clinton just just got a blow job in the closet, which means he loves America I guess?
- The morning of 9/11, Bush made a photo-op appearance at a school. There is footage showing Bush sitting in shock with a stupid look on his face after he is notified of the attacks.
Um, what? The president was visiting a school. The attacks happened. Cameras were there because they are always there when the president is. How the hell is this some kind of calculated photo op? It isn't, Moore is a moron if that's one of his main accusations. Wait, scratch the end of that sentance and leave it at "Moore is a moron."
- There is a very moving interview with a mother from Flint, Michigan... She talks about opportunities, Flint, America... then later she talks about her feelings following the death of her son in Iraq.
And a sob story to wrap it all up, to make the fake hatred stick. Very classic. After all, "think about the children!!" gets them every time.
Give me a break, your review makes this movie sound like exactly the BS I imagined it would be.
BOINC is a client wrapper for a multi-project system. When you attach to a project it will download an executable for the project which does the actual work. In the preferences for your account, you can specify how many processors on your system you want it to use. This is open-ended, as in you put in a number, so I assume if you somehow have 24 processors it will use all of them if you tell it to. It does this by simply starting a second, third, etc instance of the project executable. You can also assign a percentage to each project to split your time in any fashion you want. It alway runs low priority and you can specify if it should run always, after a certain idle time, or only during certain hours of the day. You can also set up different preferences for home, work and other.
A paintball gun typically fires ar 300 FPS , NOW Lets say they crank it up a bit for the increased payload and no need for a saftey threshold to homans. Ok now if youve ever been hit with a paintball at 450 fps, it hurs and hasforce behind it.
Firing that at a potentially explosive package with the limited range (300 ft) I think Ill just have to passon that one
Well, good thing you're not in charge. You'd rather go up to it and kick it instead?
Furthermore, most explosives don't go off when you hit them, regardless of what you remember from Bugs Bunny. You fire this into a pile of trash on the side of the road to see if there if there are bomb-indicating chemicals in it. Get a clue before commenting.
This is ridiculous. They don't have a 'likely to commit a murder' database.. or a 'likely to rape young women' database.. unless those people have already committed crimes.
Um, yes they do, a Mob family tree is a "likely to commit a murder" list. If you live with a known terrorist, each lunch daily with them at a cafe across from a federal building, take trips to the same cabin in the woods he does, purchase fertilizer at the same farm store he does, and take pilot lessons at the same school don't you think it might make just the littlest bit of sense that you could be a terrorist too? It's hardly ridiculous, it's probably the smartest way to find terrorists. However, the privacy issues make it hard to decide how important it is to track this information.
Furthermore, the article clearly states that this was just used to point out where further investigation was necessary. People were never arrested on this information alone.
If there are 120,000 people on the list, shouldn't there have been more acts of terrorism in the US?
That's moronic and naive. Terrorism doesn't involve a single lone individual commiting a single lone attack. There needs to be funding, safe houses, communications, planning plus multiple people to carry out the acts. Furthermore, the article states nearly all the 9/11 terrorists were on the top of the list, plus further arrests were initially made after more evidence regarding them was found. That means the list worked and prevented the attacks you are looking for.
Look, there is this little thing called "intrinsically safe equipment". It refers to a device that has be well tested and designed to ensure that it cannot cause any type of spark when in normal operation. These devices are used in all kinds of potentially explosive environments such as mines and areas with fuel leaks by cleanup teams. It's a well developed industry, and I've use such equipment all the time. Normal electronics are not so well designed. It's not the act of ringing, nor is it the cell phone signal that can start a fire, it's things like relays and switches and metal on metal contact which are the problem. A flip phone has a switch that can spark when you open it, plain and simple, no argument.
Yes, static electricity is a much more likely cause on average, but don't play armchair fire chief and think you know more about something just because you read slashdot and watch TV. *sigh*
The only reason you eat Fugu is because you could get poisoned, and also due to effects of trace amounts (hopefully!) of the poison. "Safe" Fugu will not have any market value.
Simply go into the store with a metal spike and poke 12 holes in each of the 12 packs until you find one that doesn't leak.
Give me a break, you're not going to do much to cheat the system. You'd have to be lucky enough to be in the right store in the right state in the first place.
Oh, come now. It's much more interesting for the news to show death, destruction and pain. Ongoing success is so boring, which is why news outlets look for, encourage and enjoy failure even in the midst of success.

Why arnt ion drives used more?

If you RTFS, they did a snapshot of the old database back in May.

Yep, and it only makes sense if the rest of the universe is also the center. Cosmology is weird, don't try to apply common sense to it.
