You (the gov't) subpoena the content from the service provider? Sure, here's an encrypted copy. We don't have anything else. Need that decryption key? Go see the sender or recipient. We don't have that.
And in the case of properly utilized public/private key encryption, see both the sender and the recipient. You will need both private keys to decrypt the message. And no, the mail transport and storage host should not have either private key.
I sympathize, but then again I do not see large numbers of people moving to Antarctica or Greenland.
I don't see large numbers of people moving to seasteading, which is a much closer analogue to space settlement.
Having said that, I don't think any of the four destinations is any indication at all of the will present to move to such places. All four are very capital-intensive places to live, but with the massive concentration of wealth happening in the US and around the world, very few people with the will also have the capital to do anything about it. With respect to the fourth destination, space, only one person in the entire world has both the will and the capital: Elon Musk.
There may be hundreds of thousands, even millions, who are willing to risk the frontier, but only a handful of them are suicidal about it. They're the ones who signed up for a one way trip to Mars. The rest are aware that it takes a significant amount of money to do such a thing, and they're aware they don't have that kind of money.
A single average-sized car puts out 4.75 metric TONS of carbon every year
Bullshit.
Density of gasoline: 0.73 kg/L Typical gas tank capacity: 57 L Typical number of fillups per year: 52
0.73 * 57 * 52 = 2200 kg/year.
Gasoline contains various different organic molecules starting from hexane and running up through decane. Hexane is C6H14, so the carbon makes up 84% of the mass. Octane is C8H18, so the carbon makes up 80% of the mass. Call it 82%.
A single average-sized car emits 1800 kg of carbon every year. Less than 2 metric tons.
Did the NSA screw up again while tapping in into the TW infrastructure?
Yeah, NSA is busy upgrading all their gear. They took out Charter earlier this week. Today it was Time Warner's turn. They'll get to Comcast in a day or two.
I have no doubt at all that Oracle committed fraud and lied a lot. I have no doubt Oregon's project management failed to give adequate oversight to the project, failed to adequately specify the project, and repeatedly changed what little specification they provided.
Neither matters. I have no doubt this lawsuit will ultimately fail, because the Oregon attorney general doesn't have the technical ability to prove the fraud and lies. The state has already proven they don't understand what they're doing. We're about to get a second demonstration.
Is there no end to the Elon Musk worship on this site? Once again, SpaceX does something perfectly normal and ordinary that's been done for decades and the fawning by corporate shills starts immediately.
What corporate shills? SpaceX is not publicly traded. They're privately held and self-funding from their own profit. What is said about them on random Internet discussion forums has absolutely no affect on their continuing success or failure. They will have to have a satisfactory explanation for the contracts people who have put down heaps of money to buy launches, but none of those conversations will involve random Internet discussion forums.
We're spectators, having a rather short and noncontroversial discussion about a small explosion in the sky. What are you, that you feel obliged to shit on the subject? A corporate shill perhaps? Employed by a SpaceX competitor?
Probably not. You're just a random Internet misanthrope.
The weight of lithium is pretty irrelevant. There are no currently existing battery technologies where Li is more than 10% of the total weight of the battery, and standard battery types are significantly below that.
He was probably referring to the elemental weight, not the weight used.
Some new game changing battery/supercapacitor breakthrough might be just around the corner. If so, all that investment in the battery megafactory could get wiped out. Ditto with investing in lithium mining.
It's not much of a risk. Every single battery chemistry has been played with, at one time or another. And by that I mean rigorously and exhaustively scientifically investigated. In consequence, not only has everything been tried, but we now know what works and why it works. That's why it's science, and not merely engineering.
Lithium will always remain a preferential element because it's the element that is the strongest reducing agent in the periodic table, short of hydrogen, which is too hard to hold on to. The stronger the reducing agent, the higher the voltage a cell can develop and the better a battery can be. At the other end, you want a strong oxidizing agent. Fluorine would be ideal, if it wasn't such a viciously strong oxidizing agent that it eats your whole battery, not just the electrons you want it to. Presumably this situation is what the spokesdroid was referring to, without explaining what the hell he was talking about.
Lithium is the cathode of choice since it's a metal that can be conveniently nailed down while still possessing a very good electrode potential. As an ion, it's nicely compact, being the lightest of metals, so it migrates through a battery most conveniently. What to pair it with is a little more complicated, and the subject of much research. This is where manganese, cobalt, and carbon come in. Various combinations of those elements and their immediate neighbors on the periodic table are used to make anodes. Some work better than others. Some may work better yet depending on how they're assembled.
Rest assured, whatever develops in terms of battery assembly, lithium will remain the cathode, and much of the macroscopic assembly will be the same or close enough to the same that the gigafactory will always be busy. The assembly and packaging to be done is fairly common, regardless of chemistry.
You're probably correct, at least for the prospects of an initial outpost. Except for freezing sewage. I can't imagine they'll ever have excess sewage to freeze. All that water gone to waste. Not to mention valuable nitrogen and readily metabolizable organic material. More likely it will get processed and its constituent parts reused, and fairly quickly. Yes using human waste as feed stock for food plants is a little risky, but the chill and near vacuum conditions allow for industrial processes that could mitigate the risk rather cheaply. It certainly won't be an option to once-through all that material. A closed cycle will be required.
Cubes do seem to be likely, for an extended period, despite the issues with pressurizing them. Ease of precise assembly and speed of assembly will be the watchwords for building pressure vessels.
In any case, it'll be Elon Musk making the real decision. I suspect hexagons will get short shrift.
Notify customers of these big ISPs that within two months they will no longer be providing the full service via that ISP.. sit back and watch the ISPs customers leave in droves.. of course, this is just turning the tables on the ISP net neutrality rules, but when the ISPs are already playing hardball and have their own man in charge of the FCC, then it's time to give them a taste of their own medicine.
You forget who Comcast owns. They wholly own NBC and Universal Studios, two major sources of Netflix content. And they're already screwing with the availability of NBCUniversal content on Netflix. If Netflix tries to play hardball, a whole boatload of shows and movies will just vanish out of their catalog.
A media company that owns the last mile is an abomination, and the FTC should do something about it.
That didn't help the Pretenda Law people, they had a Steele at the helm and they still were forced out of business by the courts over their fraudulent and illegal activities.
It is not illegal for a "drug addict and a pimp" to be engaged in some sort of dispute.
But they soon will be doing something illegal! I mean look at them. They're obvious criminal types. Her clothes and his hat offend the sensibilities of all decent right-thinking people. Obviously they should be locked up.
Call of Duty is nothing like actual war. instead, you should make the kids go camping for 3 days with nothing but ritz crackers, peanut butter and beef jerky....
That was brutal. Worthy of Jon Stewart, except he was the guy standing next to the generator, thinking he was making the jerky taste better.
My mod points expired a couple of hours ago, but I'd have commented anyway. I am in awe.
Nobody has been able to explain what correct usage is, however.
The Chicago Manual of Style has detailed explanations of correct comma usage. So does Strunk and White's Elements of Style. You can also look up individual recommendations. Things like the Serial Comma have Wikipedia articles that quote both of those sources as well as half a dozen more.
Commas to delimit prepositional phrases have only recently been deprecated. I was taught to use them as well.
...and the Falcon 9 Heavy test launch won't happen until that rocket is ready.
And in any case, the US government isn't paying a nickel for Falcon Heavy design or manufacturing or that test launch.[1] So they have absolutely nothing to complain about.
Right now Space X has a bunch of former NASA people working for them...
Has since the very beginning. Elon Musk is no Tony Stark. He doesn't design it all himself. He pays people who know what they're doing to design things, and he decides which option to take if there are several choices, and he uses criteria like reliability, manufacturability, and cost to make his choices, instead of "which lobbyist will give me the best vacation package to Aruba this year."
It also means that Space X is no longer profitable.
Well, he is not going to. We have several ACs running around that obviously work for ULA and are desperate for their jobs. GothMolly is one of those POS that will continue to troll and astroturf.
I haven't seen nearly as much out of those people in the last several threads about SpaceX. Now that Falcon 9 is one of only four rocket families ever developed that have had 11/11 successful launches, the ULA partisans have very little to talk about.
Imagine that -- "They hate our freedom" and yet spared Lady Liberty. This official conspiracy theory is coming apart at the seams. Toto, I get the feeling we are not talking about those terrorists anymore.
You're talking about people who think flying a plane full of people into a target is a good idea. They're not playing with a full deck. In this case, Osama Bin Laden had a particular beef with US banks in general and those housed in the Trade Center in particular. He'd already made one attempt on those towers, with a bomb in the basement. I find the choice of the Towers makes it more credible Osama Bin Laden paid for it, not less. He didn't give a rat's ass about a statue. He hated US banks, who have been using the US federal government to project power worldwide for over a century.
Maybe they weren't crazy. Maybe they correctly identified their true enemy.
I would bet any amount you care to name that you can rent a gasoline generator in Florida. And those rental companies are not treated as public utilities, no matter how long you use it.
Sorry, Virginia. Got distracted by the California vs Florida argument further down the page.
This keeps the property-owners initial costs low while locking them into a long term electricity contract. And it makes the provider a public utility--they build plants and sell electricity to customers--and therefore are unhappy to find themselves categorized and regulated as such under the laws governing public utilities.

Why would they specifically glow in the infrared? I know that the infrared spectrum glow for dyson spheres is popular in science fiction literature, but I never understood the fixation on that particular part of the em spectrum. Why not something colder, like microwave radiation?
That's an interesting theory. At the moment, we don't really have means to extract additional energy from waste heat, so it ultimately radiates off as infrared. But if we're seriously considering building a Dyson sphere, one supposes we've already exhausted every possible efficiency we can come up with, including reducing infrared wavelength all the way down to microwave wavelength, squeezing every last possible watt out of it.
It doesn't seem likely. Black body radiation at room temperature and cooler is almost entirely in the infrared. It's the part of the spectrum to which heat converts most readily at lower temperatures. Efforts to convert that infrared back into something useful have been covered on Slashdot. It's apparently possible. But the result is still infrared, coming off the back of the converter. Just less of it. One supposes it has something to do with the fundamental nature of macroscopic matter.

That would be the MBA who said no we can't afford to buy that much connectivity, cram it all through one connection. 'cause we need more PROFIT! MOAR!
