Security has to be some combination of software design and user expertise, not just one or the other. To say it's all the users fault is short sighted. Do you expect every computer user to understand what a firewall is and how it works? That's just not going to happen without spending *massive* resources on educating people who probably don't want to be that educated. Some people just want to use computers not manage them. Should we start requiring a license to use computers to force people to learn?
If a car manufacturer released a car whose brakes randomly stopped working, and as a result lots of accidents started occuring, who's fault is the whole thing? If the manufacturer puts out a recall, but the car owner doesn't respond, and then gets into an accident, who's fault is it? I definitely think it's not one or the other, no matter how you look at it.

There's way too much whining in this thread. I don't like the changes, but honestly its his movie, not yours. It doesn't matter if you had some life changing experience or epiphany when you saw it. You don't own the story. If he wants to release a new version where Jar-Jar makes a cameo during the "I'm your father" scene, then so be it. You still have your movie and your moment. He can't take that away from you. Just enjoy it instead of calling him stupid (or other unoriginal insult) because you disagree with his changes.
The fact that you can still see the original movie if you want is what takes my sympathy away from the whiners. It's not as if Leonardo was painting a mustache on the Mona Lisa. At worst it's like Leonardo using new technology to make a Mona Lisa II with a mustache and then selling it. Who cares. The original is still the original.
If you are that desparate for DVD, find the best available source (laserdisc, old print) and pay for the transfer yourself. Why does he have to subsidize the transfer for you?

Whether you like it or not, it's not very accepted in science to sacrifice human life in anyway. There's a LOT we don't about sending people that far away, and it's risky. To say that we'd leave them there with no way to bring them back is not going to sit well with a lot of people.
You could argue that exploration itself is dangerous, and that explorers take far greater risks to reach farther, but I think that they take them on their own. They aren't billion dollar state sponsored risks. You may be willing to shell out cash to watch a guy live on Mars for 2-3 years and then possibly fall to unknown illness, or even something mundane on earth like the flu, and have no recourse but to watch the person die. I don't think most people are ready for that.
I wonder how great of a project surface this really is. They say it can be projected on from either the inside or outside, meaning that the surface is really reflective. But they say in the article:
"Since the PV-TV screens don't have the luminosity of liquid crystalline or a digital TV screen, they perform best when there are no other competing light sources, according to MSK spokeswoman Aya Tanida."
That means you can only use it in the dark? i.e. nighttime?
Also if it's really reflective, isn't that going to cut down on the electricity production? I'm sure they have thought about all this, but it's hard to tell from the article. Maybe they have a reflective surface in the middle, the solar collection just outside of that, and supporting material sandwiching that.
It seems pretty neat, but I wonder if they could increase the solar efficiency if they dropped this nighttime only projection feature.
The starter motor is just too small, and definitely not designed for continuous operation. If you re-engineered it, so the motor could handle continuous operation, and you put in a bigger battery, then you'd be halfway to hybrid already. In which case you'd go all the way, because the half-breed would be overkill for starting, but not big enough to make a real dent in fuel usage.
The real loss in fuel isn't in standing (when you are at idle and under 1000 rpm) it's when you are accelerating from all the 'go' of stop and go. When you come out of a stop light you are at more throttle than you are going 50 mph, but you are accelerating through the 0-20 mph range and upwards of 2000-3000 rpm. So you are using a bunch of gas, but you aren't going anywhere. You're just using the gas to give the car kinetic energy, which you then dump into the brakes when you need to stop. That's where the hybrid really save fuel - on recovering braking energy. It also allows the engine to operate in its optimal range most of the time, instead of revving up at every stop light.
I'm sure it would be neat to go through and read a lot of these papers, but it's going to be very hard and very slow and you are going to have to have tons of background material at your side just to get the most basic meaning from them. I can't imagine reading papers in my field and getting much meaning from them before I went to college.
IMHO, if your goal is learning, you'd be much better off with some good textbooks. I know a textbook isn't as glamorous as reading the most cited papers in physics, but you'll make way more progress towards learning your area. There are some really good textbooks out there in most fields. And after getting through a few good textbooks you'll be able get through a whole lot more of the glamorous papers.
If you don't know where to start, just find your favorite university's web site and skim syllabi for the classes that interest you. Even better would be to peruse through MIT's Open Courseware, or even registering for classes at a local CC. All of course, if you aren't already headed to an undregraduate degree...

Sea salt has a lot of chloride, not chlorine. Not much oxidation power left in chloride. There are other redox reactions that can happen, especially since a lot of the metal around the computer has some potential already on it. Add in the high activity of concentrated salt solutions and wide variety of ions present, and you get accelerated corrosion.

I have about 31500 miles on my 02 Civic. Sticker said 30 City, 38 Highway Lifetime average of 31.9 I don't think it's reasonable to quote a max or min for a single tank, but for most freeway driving I get something close to 34-35 and for city I get something around 30. I don't know how to assess exactly how much city vs. highway driving I do, but I've averaged 43 miles/day in the time I've had the car. That includes some long trips, and a pretty good amount of city driving.
6. Google search by default takes you to the "I feel lucky" page. What was wrong with the normal search?
Not sure what you are doing here... There's a google search bar to the right of the address bar. If you type something in that and hit enter, it takes you to the search results for that query. If you type your query into the address bar, then it'll take you straight to the I'm feeling lucky result.
I don't think this is a bad way of doing things, but some people prefer the way Mozilla (not Mozilla Firefox) does the search, where you type a query in the address bar, and then hit the down arrow for a "Search Google for 'blah blah'" option. I may be missing something, but it sounds like you are typing your query into the address bar, and not the search bar.
Am I the only one who thinks that "Swedish Pirate Demonstration" would have been a better article title?
My imagination cooked up some confusing stuff in the short times before my eyes made their way down to the description. A game where you are a Swedish pirate raiding Danish ships? A new P2P program written by a Swede? Maybe something involving a Swedish demolition guy?
Anyway, that's pretty neat that there were organized demonstrations. Hopefully it'll get some press (outside of the/. type community).
"poly" changes it completely. Binyl chloride is pretty nasty (much much worse than ethylene glycol), but polyvinyl chloride is PVC and that's all over the place. Generally when you polymerize a monomer you are using up the reactive sites that would normally cause toxicity to form bonds with other monomer molecules. The same thing goes for a whole lot of other monomers.
Polyethylene glycol is actually really bio-friendly. Proteins don't stick to it well so it can be used in the body. You can even eat the stuff. I can't think of specific products, but I know it's on the ingredient label of lots of things we eat.
You either need water moving at a good velocity (kinetic) or some sort of height difference (potential) to generate a reasonable amount of power. (assuming you don't want a enormous paddle) I doubt you'll be able to dam the river in any way yourself without getting some sort of permit, because dams can have serious environmental impacts.
It seems to me you'd need a critical mass of people who are interested in joining a random floating network for it to be of any use at all.
Most people use their wireless to connect to the real internet, so what do they gain over the conventional internet. Some of the ideas listed on the website (which is getting thrashed at the moment) are redirecting conventional.com websites and streaming music. Might be nice in a place where people are already motivated to get together, i.e. a convention.
It's a good idea, but it's basically a cost issue. Capital costs for the type of system you are talking about large. On top of that the system has to be designed specifically for the location you are at. Also all the components of the system (your fridge, PC, air conditioner, any thing that puts out heat) would have to be designed into this larger heat transport system.
Basically unless you are in area where energy requirements are tight (i.e. space shuttle/station) or somewhere with massive energy costs (large factories/buildings), you don't run different heating and cooling lines over the place. It's just not cost effective.
It would be a neat do-it-yourself project, but there's not much drive for development of consumer level systems like this. Not to say there aren't products; I'm sure there are.
A lot of supercapacitor research uses activated carbon, which can have specific surface areas in the range of 50-1500 m^2/g. Activated carbon is basically charcoal heated in the absence of oxygen, which leaves a really porous structure. And it's super cheap. Not sure about carbon aerogels though.

From a practical perspective liquid hydrogen and liquid peroxide *are* pretty dangerous. While it's true technically that 'liquid hydrogen' isn't going to react with gaseous oxygen readily, it sure doesn't take very much to turn liquid hydrogen into gaseous hydrogen (i.e not very much heat). In other words if you hold a burning match over an open container of liquid hydrogen it's probably going to start a serious explosion well before the match gets down to the liquid. Once the vapor above the liquid is combusting, you can guess what's going to happen to the remaining liquid...
The same goes for a spark, which is reason the parent said it wasn't good for an intercooler. Not that there's sparking going on all over the place, but you don't want to have the potential for an explosion if there happened to be a leak and an ignition source near each other.
Has no one else noticed that this approach is: a) fairly invasive? To treat a lot of blood in a short amount of time you need a pretty good flow rate. Which means you need a big hole in a big artery. I don't like big holes in my major arteries, but that's just me. I suppose if you were fitted with some sort of interface/valve it would be fine, but if you started bleeding through that hole later you'd be in serious trouble.
b) very specific? You have to make an antibody/couple for *every* molebule you want to catch.
I think this is more hype than something practical, at least for the time being. It might be different in a while after they've developed it (and done lots and lots more human trials.)
What's to prevent a malicious person from generating a script to 'click through' on ads from random searches? It doesn't cost the malicious person anything, but it costs the advertisers dollars every few clicks. What would google do to separate the real users from the malicous person. Or even worse what would they do if the script became distributed?
Someone might have already addressed this, and I'm sure Google has some plan (hopefully) but does anyone know what they might do?
You don't feel bad for the people who are just as careful as you, but still get RSI related injuries? Trust me, they exist. Your sample size (1 person) is a little small to be making such big statements.
A little google search of 'repetitive stress injuries predisposed' will net a whole bunch of hits. It's not a journal article, but I'm sure you could find one if you looked.
From: here.
"You could also be genetically predisposed to CTS, as some people's tendons are not as slippery as other people's. Folks with other medical conditions such as gout, diabetes, rheumatoid arthritis, and alcoholism seem to be more susceptible to CTS, as are women experiencing hormonal changes. Job stress seems to be another factor."
