If we are to have telemedicine, displacement of copper telephone infrastructure, etc., then we do need guaranteed levels of service for some things.
Traffic shaping is not necessarily opposed to net neutrality. I see nothing wrong with prioritizing traffic based on how much a customer paid, or how much bandwidth they've used recently, for instance. An ISP account should come with X gigabytes/month of "first class" service, where you get to decide what to send/receive first class, and the rest is bulk. I have wasted too much time kluging with LARTC. Traffic prioritization needs to be end-to-end, not just at the network layer of one end.
Because the American government has known, probably since Reagan, that its' constituents have genuine grounds for overthrowing it, and that it is therefore reasonably possible that they could someday try...and that they must therefore be prevented from trying at all costs.;)
Bull crap. I will believe that after, and only after, the government has rejected the outcome of an election (or there is massive vote fraud). Unless and until that happens, were are getting exactly what we ask for, good or bad as that may be. When Obama began his campaign I don't believe either party thought he had a prayer of winning.
Have you ever worn a bike helmet that was 3 sizes too large? How effective was it?
You've got it wrong. In a bicycle helmet, the space between the shell and the skull is occupied by foam. That space allows the head time to decelerate more gradually. In the nylon webbing suspension system, that space is filled mostly by air, since the webbing holds the helmet off the head. But the webbing resists the movement of the shell towards the skull, just like the foam in a bike helmet (and also the foam in newer soldier helmets).
Now if they were talking about a grossly mis-adjusted helmet where the helmet is adjusted for somebody with a much larger head, you would have a point.
Any way, the effect you're talking about has nothing to do with the suspected problem of an air pressure wave being focused by a helmet.
with indirect shockwaves (i.e. an IED going off a few meters away) the helmets have been shown to increase the likelihood of a TBI.
Have they? TFA is slashdotted apparently, but the study cited in the blurb isn't nearly that conclusive. What it does show is that, in a computer model, there are some conditions where what you said can happen, though less so in newer helmets than older ones, but there's a tradeoff between this underwash and the shock transmitted by the suspension system itself to the skull. In any case, the results could be very different depending on the angle between the blast and the helmet. Therefore, whether the helmet is more likely to hurt or help in a statistically representative blast (much less help or hurt on average over all battlefield injuries) is not so simple:
We next studied how helmets and their suspension systems influence the blastinduced
mechanical loads in the brain. We considered two common suspension systems
that accommodate the ballistic standard of a 1.3 cm gap between helmet and head (24):
a nylon web system, as formerly used in the Personnel Armor System Ground Troops
[PASGT] infantry helmets, and viscoelastic foam pads like those in Advanced Combat
Helmets [ACH]. The helmet was modeled as a hemi-ellipsoidal Kevlar shell in both
cases.
Figure 4 is from a blast simulation of a helmet with a webbed suspension. The
1.3 cm gap allows the blast wave to wash under the helmet. When this "underwash"
occurs, geometric focusing of the blast wave causes the pressures under the helmet to
exceed those outside the helmet, so the helmet does not prevent the rippling deformation
of the skull and the pressure gradients in the brain. For ACH-style foam-padded
helmets, this underwash effect is mostly prevented, but motion of the helmet is more
strongly coupled to the head. Helmet accelerations and bending deformations are
transferred to the skull more effectively. The simulation results are very sensitive to the
rate-dependent mechanical stiffness of the foam, which is not a well-measured quantity.
Consequently, we varied the foam stiffness from values measured at low-rates to values
three orders of magnitude larger. Foams that were stiffer at high loading rates
transferred greater forces from the helmet to the skull and increased the mechanical
loads in the brain relative to softer foams. But even soft foams only partially reduced the
blast-induced pressures and pressure gradients in the brain, because the helmet does not
cover enough of the head at the back and sides to prevent skull deformation.
But if you or TFA are saying that the helmets have been proven to statistically worsen the outcomes of blasts in the real world, I would appreciate a (non-slashdotted) link.
Game development isn't just about programming anymore. Artwork isn't tightly coupled like code is. OK, you might like all your maps, characters, and music to be in a consistent style, but they don't have to match for the game to run.
Researchers have been sounding this alarm for years, if not decades. But what makes this significant is hearing it from the likes of BusinessWeek. If the Wall Street Journal ever catches on, we might be close to some real change. On the other hand, they are sure to think the solution to tragedy of commons is stronger IP laws rather than more investment in commons.

Virtual Bank Woes

· Score: 2, Insightful
How is the online world coping with the new institutions it must create with the added complexities of fast growing virtual worlds? Will it find a new way of doing things, or just repeat the same mistakes (this looks like repeating the same mistakes that were made a few hundred years ago).
They will evolve more or less the same rules as in the real world, for the same reasons. Then the next of idealistic young libertarians will get frustrated with all the rules, which they don't really understand, and set off to create a freedom utopia, and the cycle will repeat.
This article is really just one guy pointificating about a few anecdotes. Of course he's right that the mass market is in the middle to low end. But what was it not so? Ford outsells Ferrari. This is not news.
Oh, just shut up. You you have no good reason to think this won't work, this is just your biased gut reaction to anything associated with efficiency or alternative energy savings, and nothing more. Lead, follow, or get out of the way.
The two tracks that take 90% of the wear in each lane cover relatively little of the road, and this doesn't have to be cost competitive with non-energy producing roads because energy is valuable! Roads cover vast swaths of space, which is mostly wasted. So I really hope this works out.
China? Why? If they wanted to, they'd put trojans in a few of the millions of laptops that actually are built there every year instead of doing something odd like this.
For that matter, they would make it appear to be an exploitable bug in the ethernet driver (or something) instead of being so obvious. Sheesh, they're not stupid.
I agree, but on the other hand, I don't think grammar matters that much either way. The vastly more significant change brought about by the Internet is that far more people write and receive feedback on a regular basis. Feedback is crucial. As a kid, your mom will glance over your writing and tell you it's wonderful. In a college writing course the professor might bother to read a few pages of your writing throughout the semester, or more likely force a grad student to do it. On slashdot, you get feedback within minutes - and it's unvarnished feedback, too. Very quickly you learn how many ways people can misunderstand what you're saying, and how your foes intentionally misinterpret what you write. And you learn that long-winded writing tends to be ignored completely.
So I don't think grammar is the most significant thing, and I don't think simply giving more people the chance to write and be read is the most important thing (although it is important). The big revolution is feedback.
There's already a "Do not call" mechanism that's ignored.
Junk phone calls are just a small fraction of what they were before the list, I'm surprised how effective it has been. So, I'm all for closing remaining loopholes.
Remember, that's a translation of what Chavez said, rather than what he actually said. From the context, I wouldn't be surprised if the word he actually used has negative connotations similar to "loner," "isolation," and "exile" have to us.
It is utterly meaningless to take the top 5 of the 195 nations on earth and define any of them as "low" because they're low within the top 5. It's blatant cherry-picking.
Here's the company that makes the systems. I doubt they have anything against selling them to Japan, but then they probably have competitors selling them there, too.
Having people stand around counting pills is just stupid. That's what this is, an automated pill-counter hooked up to a database so individualized medicine packets can be packaged at a high rate.
No, it has nothing to do with vending machines where you would presumably put in some money and select a drug. All the people riffing on the intentionally misleading headline are just being sucked in, as usual.
Execution rate inversely proportional to homicide rate? Interesting correlation...
Did you read the above thread at all? The US is near the top worldwide in both execution rate and murder rate. That implies "proportional," not "inversely proportional."
The problem is what is expensive for society is often profitable for some special interest. Please read this article, even though I am about to quote part of it:
[California] spends as much money on corrections as it does on its higher education system....
In three decades, the California Correctional Peace Officers Association has become one of the most powerful political forces in California. The union has contributed millions of dollars to support "three strikes" and other laws that lengthen sentences and increase parole sanctions. It donated $1 million to Wilson after he backed the three strikes law.
And the result for the union has been dramatic. Since the laws went into effect and the inmate population boomed, the union grew from 2,600 officers to 45,000 officers. Salaries jumped: In 1980, the average officer earned $15,000 a year; today, one in every 10 officers makes more than $100,000 a year.
Lance Corcoran, spokesman for the union, says it does what is best for its members. "We have advocated successfully for our members," he said. But he disputes that the union has purposefully tried to increase the prison population...
Campaign records, however, show much of the funding to promote and push for the passage of the laws came from a political action committee the union created. It is run out of a group called Crime Victims United of California. Its director, Harriet Salarno, says the committee is independent from the union. But a review of the PAC's financial records shows the PAC has not received a donation from another group besides the union since 2004.
(Granted, the salary statistic is irresponsible, since they compared the average 1980 salary to the top 10% salary from 2009, without even adjusting for inflation. $15K in 1980 is equivalent to $39K today.)
Anyways, this is the problem of special interests in a nutshell - a few people who have a lot at stake can wield disproportionate influence. It happens all the time in the US, presumably in China also.
That appears to be the entire program cost: "Long term acquisition requirements call for 12 complete systems at an estimated value of $1.6 billion." So, yeah, each one is almost exactly an order of magnitude cheaper than you are thinking.
I know the Pentagon pays quite a bit for stuff, but even the B2 Stealth Bomber are less than a billion per copy.
Come to think of it, I've only had it actually lock up when running VMWare from that ntfs partition. VMWare can be very disk intenstive (snapshots, suspend+resume) and runs largely in kernel mode, maybe it's choking on the delays?
I'd be very curious what you get from the following test - here is my output from running the following command on both ntfs and ext3 filesystems:
time dd if=/dev/zero of=test bs=1024 count=2000000

As you can see, the ntfs-3g write speed is slower by a factor of 8! Moreover mount.ntfs saturates a core under sustained writing. It's just not good enough for running an i/o intensive application on.
At least linux tries. But there is a fundamental shortfall at the moment - lack of support for a common filesystem! Windows only does NTFS, and NTFS-3G in linux grinds to a halt and freezes if you write substantial amounts of data. (This is most often noted by people trying to run VMWare images on an NTFS filesystem from a linux host, since suspending and snapshotting the guest take lots of space). That leaves you with fat32, and 2GB files aren't what they used to be.
Many Polish people may indeed be nationalist, they may be anti-semites, russophobes... but racists? There are just not so many black people in Poland. Microsoft was probably right thinking that having black people in the ads would not connect in a 99.9% white population.
Not identifying with people of other races is exactly what racism means. In fact I don't think I could make up a better definition.
Yes, Virginia, many or most (all?) people are at least a little racist at some level. Subtly altering a candidate to look more like a voter makes that candidate more likely to receive the vote. Most Americans find it easier to associate words with negative connotations with blacks and positive connotations with whites. Yes, racism is almost universal to some degree and probably natural. Does this make you think it's ok or unimportant? To me it makes it all the more problematic.
