The following is Burt Kaliski's description of how hard it is to crack this encryption:
Imagine a computer that is the size of a grain of sand that can test keys against some encrypted data. Also imagine that it can test a key in the amount of time it takes light to cross it. Then consider a cluster of these computers, so many that if you covered the earth with them, they would cover the whole planet to the height of 1 meter. The cluster of computers would crack a 128-bit key on average in 1,000 years.
I hope he did the math better when he did the encryption scheme.
My quickie estimate (2mm computers, otherwise as specified by him) says 5 seconds on average, not 1000 years.
I don't get it, all the free market preachers are promising that my energy problems will shortly be solved by the free market but your view is such a fatalistic-don't-even-try-jaded response that you seem to doubt the free market can provide.
No, the "free market preachers" aren't saying that. Because the "free market preachers" know perfectly well that energy production is one of the most heavily regulated industries in the world.
And as long as NIMBY exists, there isn't really an answer to increasing energy production - the people want green, but they pretty much stop wanting that as soon as the price tag is mentioned (yes, going all solar and wind will increase energy costs).
On a related note, saw in the news this AM that the windpower industry is really peeved that Congress hasn't gotten around to renewing their tax credits, and is expecting massive layoffs as a result.
Which reminds me, I really need to get off my duff and get some solar panels on my roof before the tax rebates end - much better to buy while the neighbors are paying for it than to wait until I have to pay for it myself.
The theory is that you are put into a position where you can influence the policies of the teachers below you.
That's the theory.
Can't say as I recall any principal at any school I was ever interested in (either the ones I went to, or the ones my children went to) every having any real influence on their teachers.
False. My sister has consistently been doing more, and as a reward they are paying her for the additional education requested to make her an Assistant Principal, where they want to keep her for a year before making her a full-on Principal of a whole school.
So, the reward for being a great teacher is that they get you out of a classroom and into an office?
I now live in Idaho and make half what I used to. However, my living expenses are about 1/8th of what they used to be. I was paying $2000+ in rent on average when I lived int he bay area. I now pay $300.
If you made $100k in SF and paid $12k per year in living expenses, that leaves $88k for other things.
$2K+ for rent isn't $12K per year in living expenses.
It's closer to $24K just in rent, much less in all those other living expenses.
Environmentally-responsible airplane that can also carry a wicked-heavy bomb....*sigh*
a 450 pound bomb is NOT "wicked heavy". It's more like "too small to bother with".
Note that the Air Force has one bomb size that could be carried by this thing - the "mini".
Note also that "environmentally-responsible" is meaningless when the LH2 is made the old-fashioned way, by steam reforming (yes, manufacturing H2 produces CO2, even when you ignore the energy required, which also produces CO2).
Admittedly, H@ manufacture is just about ideal for CO2 sequestration, but it's not like anyone does that yet.
Zuckerberg still owns more than 50% of the voting rights for Facebook. he doesn't have to care what the other stock holders think. it might as well have never gone IPO it is pretty much still his private company.
Can you say "stockholder lawsuit"? Sure, you can...
It doesn't take a majority of the shares to start a lawsuit against the Board of Directors/CEO.
i'm kinda with the environmentalists here. if texas really is as big as they say it is, could they not have found a chunk of it in the desert?
All other things being equal, you really want water to the east of your launch site (it's so embarrassing when your spacecraft falls into a city). You also want your launch site to be as far south as is practical.
Assuming that you can get away with no water to the east, you still want water access - it's so much easier to move very heavy things by water than by land.
Um, no, The annual deficit may be smaller, but the debt is definitely bigger.
The debt is larger.
In addition, the deficit of the Obama years are all in the Top Five All Time Deficits.
Note also that Obama is the only President in history to never get a Federal Budget from Congress to sign - the Democratic Senate has refused to send a Federal Budget to the President every year....
Not that the latter is Obama's fault (I think, I can't imagine why he would), but it is a clue to the thinking of the Senate - "don't have an Omnibus Budget Bill, and noone will know how much more we're spending than we're taking in"....
Because it's extremely difficult to smuggle a gun in from one of the other 49 states, many of which will give a gun to just about anyone.
Note that it is illegal to buy a firearm of any kind anywhere but in your State of legal residence.
Note further that a background check is required for firearms purchases from a dealer (private sales between individuals do not require background checks), and that having a criminal record prevents one from passing the background check.
Net effect for DC - law-abiding citizens cannot own firearms, criminals can. Which is paradise for a criminal.
Note also that if merely the presence of firearms causes problems, then the problems should be no worse in DC than elsewhere. And yet DC has one of the highest murder/violent crime rates in the nation.
Or that more people became criminals of opportunity as they got their hands on the weapons.
Umm, no.
Florida's Shall Issue Law had NO effect on availability of firearms in general (anyone could, both before and after the law, buy a firearm by passing the usual background check).
What it affected was the possibility of LEGAL carrying of firearms without being obvious about it.
Note that at that time, the only people who could legally carry concealed in Florida were Florida residents, since they were the first State to explicitly license concealed carry. That's changed now, with most States allowing concealed carry, and reciprocity means most anyone American you meet could be carrying.
It should also be noted that the murder rate nationally has been declining pretty steadily during the period that concealed carry became increasingly legal.
Mostly the assumption that there is a large group of people with a desire to do harm that's only been thwarted by the fact their victim's have a firearm. Something I've never seen to be true.
It should be noted that when Florida passed its Shall Issue Law, allowing concealed carry to anyone who wanted to bother, the firearms crime rate went down.
Oddly, the firearms related crime rate with tourists as victims went UP. Note that a tourist, at that time, would have been the only type of person that could be guaranteed not to be carrying.
Which at least implies that the possibility that the victim might be carrying dissuaded some of the criminal community.
"To regulate commerce [...] among the several states" is one such power. Otherwise, how is Medicare legal?
It's not, and never was. Any more than Social Security is.
Alas, if you bribe the voters with their own money (or even better, Other People's Money), then you can always count on votes.
Note, by the way, that back when FDR was busy passing all sorts of unconstitutional laws (like SSA, as an example), the makeup of the Supreme Court was NOT limited to nine Justices. And FDR threatened to just add Justices to the Court till he had a majority that would do what he told it to.
Net result - the Supremes let him get away with pretty much ignoring the Constitution....
If you read my original post, you'll find that I say our governments were actually forced/corrupted into it. The people borrowed money that was wilfully offered to them by the banks.
So, the banks held guns to your head and made you borrow money?
Somehow, I don't think so.
Do remember that the people being bribed with OPM would've screamed to high heaven if your governments had said twenty years ago "sorry, lads, but this is unsustainable - we can't afford it, you can't afford" and then stopped borrowing money.
Funny you don't mention how we were basically paid to ruin our industry and agriculture and become mass importers.
Paid how? By people being willing to lend you money? Noone made your country borrow money it couldn't afford (any more than MY country was forced to borrow money it couldn't afford).
Face it, borrowing money to bribe voters is the favorite hobby of politicians everywhere.
And, in the end, they can point to some evil "other" that made them do it, and get you all riled up at that evil "other".
Which seems to be working really well with you.
So, instead of wasting time being a naysayer, do you have anything valuable to propose?
Depends on what you mean by "valuable". If you mean "suggest ways you can have your cake and eat it too", then no, not a thing.
Alas, in the short run, you're screwed. Your government bribed you into voting for it by giving you something for "nothing", and now the "nothing" turns out to be "something". And you don't like the size of the "something"...
So, the choice you have reduces to emigrate to somewhere outside the First World (the PIIGS are leading the pack, but they're not the only countries headed into ruin - they're just going to get there first).
Which implies a lower standard of living for you for the foreseeable future, since the reason that countries aren't part of the First World is that they generally suck.
OR, you stay at home and suffer your way through the problem. Same lower standard of living, but in the long run, you have at least a chance of getting over it.
Oh, and finally, stop voting in people who offer to bribe you with OPM - it never works in the long run.

Okay, so just substitute newtons for pounds - multiply by 4.45. That'll give you the proper SI unit for weight...
So, 176,370 pounds = 785,000 newtons (approximately, can't understand why TFA gives weight to the nearest pound)
And, 50,706 pounds = 226,000 newtons.

It should be noted that "Jim Crow killings" weren't official government policy, they were the result of individual actions.
Unlike the Kent State thing, which was "official policy" at least to the extent that the Guard was ordered there, armed.

Might want to check your units too. The hour in KWh and in hour cancel, leaving KW.

It's been in there for years.
I read every version of it as it was being debated, and the final version was in there at the end.
Just out of curiosity, have they targeted Mr. Obama himself?
Citation?

So, basically this is a subsidy for theatre owners - they get to cut their costs in half in exchange for a small decrease in revenue?
Leave the Eurozone. Don't recall that anyone actually forced you to give up your native currency.
Don't borrow. Don't recall that anyone actually forced your governments (or your fellow citizens) to borrow more than they could afford.
You had huge pubic debts before your banks had to be bailed out. Don't recall anyone actually forcing your governments to live beyond their means.
Ultimately, you can choose to blame everyone but yourselves for the decisions you made. But that won't fix things, so why bother wasting time with it?
About 120W/ft^2, assuming ~100% efficiency.
With current technology, we're talking maybe 25W/ft^2.
There are better than half a million cancer deaths in the US alone every year. Your ~131 extra annual cancer deaths is a 0.03% increase, at most.
In other words, even if your estimates of premature cancer deaths is correct, the change as a result of the TSA scans will be lost in the noise....
