What I find most surprising is that they report over a billion stars with an image containing 150 billion pixels. That's a much higher density that I would have expected.
I guess that my intuition in such things isn't very good, which, not being an astronomer, isn't surprising.
Any device that can do DMA can be used to gain access to anything on the system. This includes eSATA, Firewire, PCMCIA, and probably other ports. USB does not support DMA, though that may have changed in 3.0.
It would be possible for the OS to disable most of these when the system is locked, which should be a feature of any secure OS, though it would annoy users, so don't expect it to be the default setting.
DARPA was funding research into something like this recently. The idea is that for forward military bases, such as in Afghanistan, you can install a small nuclear reactor for electrical power (much like the navy's reactors), but you have a huge logistical issue with supplying adequate fuel for trucks and planes. So the solution is to synthesize the fuel from the excess electricity, greatly reducing the resupply needs of the bases.
Apparently European countries like France that generate a lot of nuclear power are also interested because nuclear reactors don't scale their power generation with dynamic demand, so there is often excess power. If there are enough non-nuclear plants that can be idled when demand drops, that's great, but if not, then being able to produce diesel fuel for free with the excess is a good option.
I wonder if this was funded as part of that DARPA program?
Storms and weather on the sun should be expected. We are quite familiar with storms on Jupiter, so just scale that up, and you should expect the same on the sun. We just can't observe them as easily.
I would expect that they'll find that there are storms that persist for hundreds of years, if not longer.
No, you are making the mistake. The conversion in units needs to take into account the precision of the original number to determine where it should be rounded. I doubt the determination of the top speed is within 4,000mph, so the 190K number is better than the 186K number. 200K might even be more fair, but it depends on the original data. Unfortunately, the units conversions are typically done by people who don't understand the concept of significant digits, let alone have any information about how precise the original number really is.
This sounds a lot like fraud in the wine business, where a relatively cheap wine is relabeled as an expensive wine.
Both in the fish market, and in the wine market, taste tests show that consumers generally can't tell the difference. If consumers were smart, they would have chosen the cheaper product in the first place. However, consumers are often more concerned about the image of the product than the product itself, so they buy the effectively identical more expensive product.
Yes, the fraud is wrong, but I can't say I feel that horrible about it, as the consumer is still effectively getting what they pay for--something expensive that tastes just like something cheap. Perhaps the resources would be better spent worrying about crimes with real victims.
I remember seeing what was obviously a nuclear convoy in Wyoming in 1992. There were four or five slightly oversized 18-wheelers with SAC license plates. In front and behind and between each of them were armored cars with police lights and machine guns. Overhead there was a helicopter. They were just pulling on, and I ended up cutting into the middle of the convoy briefly so that one of the armored cars could move up to the front.
They were traveling somewhat slowly, probably 50mph, so I lost sight of them fairly quickly, but a ways on ahead was another armored car, and I noticed another helicopter scouting ahead. Further on ahead I saw a tow truck removing a disabled car.
I'm not a legal historian, but I think the case that convinced the Supreme Court to take a broad view of the Commerce Clause was a civil rights law that required equal access to hotels and restaurants, regardless of race.
My understanding is that the jury's job is to decide any facts that are in dispute, such as whether someone did something. A judge decides matters of law, such as whether that something is illegal. I suspect in this case that the judge determined that the jury's verdict included matters of law, and therefore were outside the jury's scope.
The books were written by an eyewitness many years after the events. The movie script is based on records from other eyewitnesses, so it's not surprising that they would remember events differently (or even correct mistakes from the books). Of course, the books are one source for the movie script, but by no means the only one.
I believe they recovered scenes from a lot of lost episodes from Australia. What happened is that the censors were quite strict in Australia, but as part of censoring episodes, they kept the clips that they cut.
All the lost episodes have fan-made recreations, using the original soundtracks (people recorded them when they broadcast), still photos taken during the filming, and recovered scenes. Some of them are pretty good, though most are painful to watch.
If you want X to be provided as a tax-supported service, as rubbish removal is for residents in much of the USA, then it is completely appropriate for the government to regulate the use of X.
This can be done in a variety of ways, ranging from strict requirements to creating financial incentives (such as where you have to pay for each bag of trash, but not for recycling or composting, which is how it works in my town).
If it's a City service, then the costs are shared among the taxpayers, so the associated responsibilities are also shared. If you pay for your trash service independently, then you have a point.
In my town, you pay a base fee to cover the trucks coming around, and you also have to buy special town-issued trash bags (which are expensive), which covers the cost of processing the trash. Recycling is free. If you want to throw away your recyclables, then at least in my town, you do pay for it yourself. With the old tax-supported system, when you didn't recycle, I paid for it.
Yes, RFID would be better, but something like Bluetooth or even turning on WiFi on a cell phone in the car could be sufficient, and it could eliminate the need to purchase equipment that isn't already on-hand. It also has a nice hack spirit if it works, in using something in ways beyond what it was designed for.
How quickly can Bluetooth establish a connection? Use the optical beams to determine the time that a car passes a point, and give each driver a Bluetooth headset that has been paired with laptops used to record the timing.
You can test the range to make sure it will work--you should only need a few meters. You can get cheap headsets for somewhere around $50, probably less.
I have no idea if this would actually work, but it should be possible to do a test run with parts you probably already have.
Am I correct that FLAC is not supported by the iPod, but ALAC is? If we're free to convert between the two now, what advantage is there in using FLAC instead of ALAC?
I'm surprised it took this long, but I guess this is when the contract expired. Once Dell tried to buy 3Par, it was obvious that they viewed EMC as a short-term partner to get their foot in the storage door, not a long-term partner. Considering the amount of money people pay for storage, I'm not surprised. We went through the same thing when HP dropped EMC back in the late 90s.
(Note: I'm an EMC employee, but I have no involvement with contracts. I did notice that we switched PC brands from Compaq to Dell when the deal was first announced, and we recently switched away from Dell--we don't like buying from competitors, it seems.)
A color 7" Android-based tablet from a major book seller? This sounds exactly like the Nook. Why is everyone comparing it to the iPad instead of the Nook?
Brazil has the worst tariffs on imports. If Apple has decided that the Brazil market for iPads is large enough, it makes sense to move production there to avoid the tariffs.
"Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed."
It's been recognized for generations that people won't rebel against a government for light reasons. As long as people have food and jobs to keep them busy, they'll tolerate quite a bit of oppression.
Yes, but the point is that it is unlikely that a man-in-the-middle attack would catch both your direct connection and a connection routed through TOR. And if the certificates don't match, you know you have a big problem.
Deciding on what to do if you detect a problem is another matter. Perhaps try a wide assortment of TOR exit nodes to get a better world-wide view.
One way to improve security is to use TOR to get the certificate as well as getting it directly. This way, if you have a man-in-the-middle attack, you will likely detect it.
This doesn't do anything against someone who is hijacking the entire web site (though DNS hacks, for example), but it does help catch one category of possible attacks.
Of course, browsers should also cache certificates and notice when they change, so you would only need to use multiple paths to get certificates when they change or when visiting a site for the first time.
The energy in subway trains is dwarfed by the energy used and lost on runways for jetliners. Imagine a system where, when a plane touches down, the energy is absorbed by a ground-based system that is then used to assist in takeoff for the next plane.
I suppose the natural first use of this would be on aircraft carriers. They already use systems to assist the takeoff, and they use hooks and cables in landing. They just need to efficiently store all that energy for reuse. (Then, again, when you have your own private nuclear reactor, energy for the catapult system may not be such a big deal.)

Just run a separate forum that requires a login and terms of service that give the producers the rights to any ideas you post.

Yup. The New Deal was the first expansion of the Commerce Clause, and after the civil rights law was upheld, it was pretty much all over.
WRONG! OSS software is most certainly copyrighted. It is the copyright law that makes the license relevant.
