I believe there is something to that effect. Companies will routinely bring a shredder around and throw in anything they can find, including mundane post-it notes, so they can't be accused of destroying something specific.
What I mean by "nature finds a way" is that individual actors, working in their own self-interest, will find ways to do things that the system expressly forbids, given enough incentive. It's exactly like trying to artificially impose limitations on nature (e.g., use a lot of antibiotics and end up generating antibiotic-resistant bacteria). "Corrupt officials" are just one example of the actors involved.
A lot of Cisco PIX firewalls out there are running 200MHz Pentiums, and they protect massive networks behind them. Layer 4 firewalling does not take much CPU power or memory. If you want application layer firewalling, then yeah, you're going to need a lot more.
They are designed to keep stuff out, e.g. guns, knives, etc. They're just not very good at doing that, even though you might think it's a completely controlled environment. Nature finds a way . . .
If it's limited to no higher than layer 4 stateful firewalling, then its not going to get overloaded. Assuming there's no bugs being exploited by attackers (if there is, you're probably screwed anyway), then an old Pentium could easily handle enough traffic to saturate the link.
If it's going to higher layers, then things get interesting. I'm also skeptical of the utility of doing that for public-facing web sites.
Prices have been coming down as more production of carbon fiber ramped up. For most of the last 10 years, the majority of production went into the aerospace industry. There's now enough production capacity to fulfill general automotive needs, too.
The real problem I see here is that like plastic parts, a break in a carbon fiber part means the whole piece has to be replaced and color matched. Metal parts can often just be banged back out and the paint touched up. In cars of yore, chrome bumpers didn't even need to be painted at all--just bolt the sucker back on. Plastic bumpers these days are a pain.
You can look good without sacrificing aerodynamics. 911s are among the most aerodynamic cars ever built, and lots of people think they're also the most beautiful cars ever built. Porsche figured out an efficient shape for a car in the 1930s, and until very recently, nobody found a better one (that being the "boxfish" design).
The little bit of improvement in drag coefficient that the Prius has over the 911 is mostly due to extra downforce on the 911. The Porsche could easily be as good or better if it wasn't designed for speeds on long back straights.
I would conceivably pay $10 for a cup where I've been shown that everything has been done perfectly from the growing location, to cultivating, to roasting, to grinding, to brewing. The beans would probably be Kona, and the roasting process would have been meticulously tweaked to perfection.
If it's just any old beans with some frothy milk added, then no. These days, a $1 McDonald's coffee is perfectly good for when I forget to buy more beans or I'm too rushed to do it myself.
That said, the donotwant tag on this story is inappropriate. This is the best news urban mischief makers could have had. A few Guy Fawkes masks should be enough to shut down this idea forever.
They have that whole mass-energy conservation bullshit, but both fission and fusion apparently produce tons of energy.
You can always "break" thermodynamics when you limit the scale in either space or time. We consider oil and coal to be energy-positive because we're not counting the energy put into the process to make the stuff in the first place (limiting the time scale). We consider solar photovoltaics to be energy-positive because we're not counting the energy that came out of the sun (limiting the space scale).
Fission/fusion work the same way. They're just releasing many times more energy than you could get from breaking a chemical bond.
Meh. Nuclear reactors of any kind use tiny amounts of fuel for the amount of energy they give out. Transmuting tiny amounts of one element will only give you tiny amounts of another element.
Some fission reactors can produce usable amounts of fuel for other fission reactors, but only because we can't find significant amounts of the output elements in nature.
ITER still makes sense on theoretical grounds; you push the boundaries of Science and something good is bound to come out of it.
The stated reason why these guys were rejected from peer reviewed journals was that they hadn't come up with a viable theory of how it works. Their data shows that it has positive energy output, but they have no idea why. If it does actually work (a big "if"), then some of the data from ITER may end up showing why this thing would work.
The numbers posted in the GP are just to get to LEO. The Saturn V got 119MT to LEO, but only 45MT to the moon. That was enough to send three guys, a buggy, and some porn. And one of the guys had to stay behind in lunar orbit (which I guess is what the porn was for).
If we're going to bother with the moon again, we'd like to do something more than just take a quick look around and scurry back to Earth, so we're going to need a lot more than 119MT to LEO.
I drive a stick. I expect most car jackers today will manage to get maybe three feet away.
More seriously, this really isn't a big deal. Car thieves use much faster and cruder methods, like hammering a screwdriver into the lock, or just break the window. Car alarms are a joke, too. When was the last time you heard somebody's car alarm go off that wasn't due to a big truck running by, or a dog brushing up against it, or kids throwing rocks?
I'm almost certain the joke is older than that, going back to the seven astronauts of the original Mercury program. Some of the early (unmanned) prototype rockets didn't exactly get into space, and these failures were more public than many of the USSR's failures.
There's a movement around the Bible Belt to home school kids to keep them away from textbooks that mention evolution, or as a general protest of government-run education. At some point, it started to become a stereotype in some circles that all home schooled kids fall into this category.
The term "space opera" is already around for that purpose. When George Lucas is giving an interview with a degree of candor, he'll usually use that term to describe Star Wars. Naturally, Lucas doesn't give many interviews with a sense of candor anymore, but I seem to remember him using it in the interview with Leonard Maltin that was in the VHS versions in the '90s.
It was my(admittedly layman's) understanding that a public/private key crypto implementation, assuming it isn't deeply flawed . . .
That last bit right there is the hard part. Making algorithms was a hard task, to be sure. It took eons before humanity had the right mathematics to make RSA possible, but that work is all done now. There isn't all that much work being done in making new crypto algorithms, because we're pretty sure the ones we have will stand up. Even a breakthrough in Quantum Computing or Complexity Theory wouldn't completely destroy everything out there. There is some work to do in hash algorithms (MD5/SHA1), but that's the exception.
However, putting those algorithms into a practical system is hard, and the work has to be more or less started from scratch with each new system. Every single entry point to the system has to be secured, including a lot of non-obvious ones. DeCSS was done because just one software DVD player mishandled the keys, and that toppled everything else.

Better idea: we'll rate Wikipedia articles by the minimum number of clicks it would take you to reach the Crate article.

Took only slightly longer than fuel injectors and overhead cams.

The problem with Lithium batteries is specific to Li-Ion, not Li-Po, which is what most electric cars are getting.
Nickel mining is most certainly damaging to the environment. TANSTAAFL.
It's about the only way to config some old office laser printers.

But it's probably all nonsense, anyway.
Not so much logic as "I learned just enough about thermodynamics to prove that the sun can't work".
They'll start naming them the way sequels get named.
Your own dogfood. Eat it.

And if you look at the other numbers for those 300HP engines, they're often getting better gas mileage than their slower predecessors.
