Re:shouldn't be legal
It is not borderline entrapment.
Entrapment in this sense is defined as: a defense that claims the defendant would not have broken the law if not tricked into doing it by law enforcement officials
This guy had *already broken the law*, he did not break any laws by going to a fake job interview. He just wasn't very smart.

Re:Homeostasis
Yes. That is my reading of TFA too. Any improvements made asa result of this homeostatic mechanism can only affect evolution if they directly and appropriately change the coding for the electron transport proteins, in mitochondrial or nuclear genes. I don't see any mention of this in the article.
Also the the io0.com and princeton.edu
articles seem to interpret Wallace's Steam Engine regulator metaphor differently The latter seems to refer more directly to what they actually found.There seems to be confusion between phenotypic expression (what gets manifested in the organism's body) and genetic information (what's actually in the genes).

Re:It think that is more about their strategies.
Secondly, the press did cover Biden's "gaffes".
They did cover gaffes — socially awkward or tactless acts. But not the "gaffes" — stupidities and outright lunacies smoothed-over as mere gaffes. For example, if it were anyone from the opposing ticket, claiming:
When we kicked -- along with France, we kicked Hezbollah out of Lebanon, I said and Barack said, "Move NATO forces in there. Fill the vacuum, because if you don't know -- if you don't, Hezbollah will control it."
MSNBC would've had a "Lebanon History Special" at prime time to show the entire nation, just how pathetically wrong that statement was — and on how many levels!
But it was Biden and up until very recently even a well-meaning slashdotter (not some Joe Carpenter) didn't realize, just how far from this Universe the man, chosen by Obama for his "foreign policy credentials," really lives.
McCain chose Palin. That was part of his strategy to energize the Religious Right AND an attempt to get the female vote.
And Obama chose Biden. That was part of his strategy to alleviate the concerns of his own foreign policy inexperience and reduce the impact of racial prejudices. That one strategy worked and the other didn't is works of the press and their now-documented bias towards Obama. The media — dishonestly — claimed, that Palin's inexperience trumps Obama's (as if they ran for the same post!), while looking the other way as Joe Biden mounted one lunacy over another.
Now that Obama has won, we might see more penance from the reporters and editors. We may even get some buyer's remorse from the voters. But they'll be justified, claiming, the papers misled them. This will be studied in journalism courses as a great example, of how not to write...

Re:"Propaganda"
Slavery - work done under harsh conditions for little or no pay. Source of definition
So how is this
1) work done under harsh conditions
2) work done for little or no pay -
The meaning of "gaffe" (Re:Sigh! Incorrect)
What he said doesn't make sense. It was a gaffe.
You know, the word "gaffe" has already been made more famous by Obama/Biden in 2 months, than the word "snafu" — by Clintons in 8 years. But this was not a gaffe, a term defined (thank you, WordNet) as: a socially awkward or tactless act. A gaffe — such as Biden's statement, that Hillary would've been a better choice than him — is still factually correct, it is just "awkward or tactless".
What Biden said — and what I quoted was only one of the pearls — was not a gaffe, and no amount of spin can help that...
We all know Biden has plenty of foreign policy experience. Experts in foreign affairs say he does.
Oh, well, you should've started with that! Of course, if you say, that the experts say, it is true, then it must be true. It is just that somewhere higher in this thread a plea was made to concentrate on "people's actual articulated positions", rather than "hearsay"...
I only listened to Biden once — he never came to my state, which Democrats take for granted. I was quite astounded, that his "actual articulated positions" were so factually wrong. And a few days later, Ann Coulter has summarized it rather well — and added one, that I didn't notice myself. You can discount her for a partisan hack she is, but she didn't invent any of his words...
We also know he is also prone to some gaffes.
I'm sorry, but, as already stated, this was not a "gaffe". Bush had gaffes: "Don't misunderstimate," — that's a gaffe or, perhaps, a misstatement, for the intended meaning is clear and obvious. Biden — as quoted — was either lying trying to burnish his and Obama's credentials, or simply having a senior moment on national TV.
Much was made of the Bush's funky "nukular", even though, it was still perfectly clear, what he meant. But when Biden is going to be needed as a foreign policy expert, who can possibly rely on his advice?

Re:Andrew Appel.

This is a common sentiment. It's also false.
Half of the 9/11 bombers had engineering degrees.
Osama bin Laden is a billionaire heir to a construction fortune. His major monetary backers are Saudi Arabian princes.
Of the 7/11 bombers (London bus bombings), Shehzad Tanweer's father is considered a prominent local businessman. He owns a successful fish-and-chop shop, the kind of entrepreneurial success that Americans would classify as prototypically middle class. Shehzad Tanweer himself was a college student.
Studies of killed Hezbollah fighters describe them as marginally less poor and more educated than Lebanese men generally. http://www.krueger.princeton.edu/terrorism2.pdf Suicide bombers in Israel/Palestine are, similarly, more likely to be high school or college educated than your garden variety Palestinian.
When you survey Palestinians, support for terrorism abstractly and blowing up Jews in particular both increase with economic and educational achievement.
William Ayers (hey, why not throw in a white guy) was the college-educated son of the president of Commonwealth Edison (the Illinois power monopoly -- i.e. a very rich and politically connected man). He "grew up" to become a respected professor of education at the University of Chicago and something of a local celebrity who launched the career of the man likely to be the next president of the United States.
Can you point out where the actual freaking EVIDENCE is for "poverty causes terrorism" is? The data suggest that, if anything, college education causes terrorism. (We'll ignore the religion angle for the moment because the numbers are too depressing and, hey, if you look hard enough you can usually find a token white guy to throw in.)

Re:[citation needed]
OK, honestly, why is this guy modded as flamebait? Sure, he said "propaganda", which has a negative connotation, but the definition that I'm reading is "information that is spread for the purpose of promoting some cause", (notice that it doesn't say anything about the veracity of the information being spread) so it seems legitimately used in this case. Please correct me if I'm wrong, but are there really that many Democrats out there who have the intention of banning all guns? It seems like the majority of mainstream democratic candidates out there just want to let the local law decide what is appropriate for their area.
For the record, I think banning guns would be really stupid at this point in our history, and I'm a registered democrat.

Re:True of all "social sciences"
This is one of the things that makes Krugman in particular so insufferable about his profession. He places far too much importance on it in relation to it's actual value. Like all social sciences... sociology, psychology, political science... economics is not a hard science.
Question: do you know anything at all about Paul Krugman's research? Have you read anything at all of his popular writings?
Here, let me help you out a little:
And just for the hell of it, you might peek at the answer key, an article Krugman wrote about his own approach: How I Work
Most young economists today enter the field from the technical end. Originally intending a career in hard science or engineering, they slip down the scale into the most rigorous of the social sciences. The advantages of entering economics from that direction are obvious: one arrives already well trained in mathematics, one finds the concept of formal modeling natural. It is not, however, where I come from. My first love was history; I studied little math, picking up what I needed as I went along.
[...]
I was, of course, only saying something that critics of conventional theory had been saying for decades. Yet my point was not part of the mainstream of international economics. Why? Because it had never been expressed in nice models. The new monopolistic competition models gave me a tool to open cleanly what had previously been regarded as a can of worms. More important, however, I suddenly realized the remarkable extent to which the methodology of economics creates blind spots. We just don't see what we can't formalize. And the biggest blind spot of all has involved increasing returns. So there, right at hand, was my mission: to look at things from a slightly different angle, and in so doing to reveal the obvious, things that had been right under our noses all the time.

Re:The other side.....
Krugman's site at Princeton has a rather interesting semi-bio titled How I work that gives a pretty good breakdown of his use of models and simplifications, most of which I think can be boiled down to "Simplified Models are great, but don't confuse the map for the terrain".

Re:Seems like a very cool guy
I had a real respect for him when he mentioned he was inspired by Asimov.
For more geek cred: while at Princeton in 1978, Krugman wrote a tongue-in-cheek paper titled The Theory of Interstellar Trade (PDF) (see Slashdot article on it).

Re:RAM-based hard drive
This would make swapping (and temp stuff) extremely fast to access, and more importantly, it would eliminate the need to encrypt your swap and/or temp partitions, as the data would simply disappear when power is removed.

Re:Wait ....
Ah, good to see yet another person who Has Never Been To Texas.
Actually I have been to Texas
:)However I base my comments on national statistics. Take a look at this data map. Unfortunately it only traces population density at the county level, so it is less than perfect at tracking tighter urban concentrations inside otherwise low population counties. It is easy to see that the tall higher population density counties are much bluer than the super-red low population counties. Yes, even in Texas. Note that the red-vs-blue is tracking Democratic-vs-Republican votes in the last presidential election, but I think we can all agree that that is a reasonable proxy for the "socially liberal attitudes" that I am talking about.

Re:Do many companies really do EFM recovery?Although the drive has to be in a living system and not on the shelf, it's worth noting the cold boot attack: http://citp.princeton.edu/memory/
Q. What encryption software is vulnerable to these attacks?
A. We have demonstrated practical attacks against several popular disk encryption systems: BitLocker (a feature of Windows Vista), FileVault (a feature of Mac OS X), dm-crypt (a feature of Linux), and TrueCrypt (a third-party application for Windows, Linux, and Mac OS X). Since these problems result from common design limitations of these systems rather than specific bugs, most similar disk encryption applications, including many running on servers, are probably also vulnerable. -
Re:Privacy hinders law enforcement
Did Bill Ayers ever try to kill anyone? I thought all he did was help blow up a statue?
WordNet defines "terrorism" as (emphasis mine::
The noun terrorism has 1 sense (no senses from tagged texts) 1. terrorism, act of terrorism, terrorist act -- (the calculated use of violence (or the threat of violence) against civilians in order to attain goals that are political or religious or ideological in nature; this is done through intimidation or coercion or instilling fear)
Belonging to a terrorist organization makes one a terrorist too, even if one is not (unlike Ayers) directly involved in any actual terrorism — take Hassan Nasrallah, for example.
Although per the definition above, simply threatening violence to attain certain goals is terrorism, Ayers' organization were planning to blow up an Army NCO club next. Fortunately for most concerned, they blew themselves up instead — the organization changed strategy to try to avoid casualties after this incident... But were also armed robberies (with fatalities) — a revolution always needs cash... (Interestingly, Joseph Stalin's first job in the Communist Party was to "rob the robbers" — what do the owners of "Democracy Now!" have in store for us?).
Just take Ayers' own words, spoken not during an interrogation, and not decades ago, but to the media this year: "I don't regret setting bombs, I feel we didn't do enough."
Whether he actually killed anyone is not relevant to his being a terrorist — only to an additional charge of murder, which, according to his "memoir" he may also have committed, but nobody knows for sure: "''Is this, then, the truth?,'' he writes. ''Not exactly. Although it feels entirely honest to me.''"
But his organization's ideology, as summarized by him back then was: "Kill all the rich people. Break up their cars and apartments. Bring the revolution home, kill your parents, that's where it's really at."
Back to my original point — although the scumbag's guilt is undeniable (and, indeed, not denied), he avoided any punishment, because of government misconduct in collecting evidence against them...
So, yes, Ayers was a member of a terrorist and otherwise criminal organization, and a terrorist himself — committed to this day to terrorism...

Re:Crows, for one
Even secular humanists believe that human beings have a certain dignity or quality not found in most or possibly any other Earth species. So unless someone is a true, hard-core atheist -- note that when pressed, most self-described 'atheists' aren't really atheists, they're really anything from agnostics to secular humanists in terms of philosophy -- then generally they will believe that humans are special.
Any chance you could describe the difference between "secular humanist" and "atheist" in your definitions? I am most DEFINITELY an atheist (in fact, I generally consider religion to be a mental disorder - and, like most mental disorders is tolerable in small amounts, but in extreme cases is VERY scary), but also consider myself to loosely follow the guidelines of secular humanism (although, don't really pay that much attention to any particular philosophical guidelines - I just follow "what feels right" for me and it just happens to match secular humanism relatively closely).
Actually, I would have thought that by its very definition, secular humanism is a philosophy that would generally only be followed by atheists.
Atheism is a lack of religion, and says nothing about philosophy. Secular humanism is a philosophy, not a religion (although, as stated, I think by having the world "secular" in it, it implies a lack of religion IN the philosophy).Definitions:
Secular (adj): Of or relating to the doctrine that rejects religion and religious considerations. Source
Atheist (n): a lack of belief in the existence of God or gods. SourceSo, I think a secular humanist would in general be an atheist. It would be possible, but VERY odd for a religious person to be a secular humanist (belief in a higher power, but rejecting the philosophy of it to follow a secular philosophy). It is certainly NOT possible to say what you said with, "...aren't really atheists, they're really anything from agnostics to secular humanists..." as one does not logically preclude the other.
Now, also just to clarify on topic here: No, I don't believe humans are anything "special", I generally prefer humans to other species (roughly the order of priority to me is: "humans I know and like", "other creatures I know and like", "humans I don't know", "other creatures I don't know", "humans I know and don't like", "other creatures I know and don't like" (yes, I would rather save the life of my pet cat than some random stranger (human or otherwise) that I've never met)) however as other posters have pointed out, that's quite natural and requires no "special status" (just as a cat generally prefers other cats to any other species).

Re:Question
Emulation == OS on top of other OS.
You are _emulating_ an _Operating_ System while it is in fact _not_ operating your computer.
Wine != even an OS so there is no emulation because it's natively run.
This means that Wine is not an OS and it's running native so no emulation here.
Only in strict interpretations of specific terms relating to a specific industry. Of course other definitions vary.
If you emulate a nuclear explosion then is there coming fire, pressure and radiation out of the server park?
Actualy, your confusing simulation with emulation. And yes, in an emilation, there would be fire and radiation.
I made the post because of the fuzzy definitions that seem to alter and become more precise depending on the institution or field of study and who you are currently speaking to. In biology, emulation would mean becoming equal to. In computer science, it means having the same capabilities. When Wine was created, if referenced the way emulation was handled at the time and attempted to create a definition from there. And all of this causes confusion.
See why you are insanely wrong now?

Also various organizations with three letters have been doing research on this for decades now.

Re:Pathetic
You have a point if this is a game where skill and wit is required.
However, I fail to see how this holds in a typical MMO hack 'n slash game where the automation is routine and requires no thought at all, especially when you're just using this to acquire certain items (among other huge differences between chess and MMOs) from a monster's random item drop. Hence the younger sibling and trained monkey used in place, not a genius or experienced player.
A concrete example in Diablo 2 would be using a bot for say, running Pindleskin, Eldricht and Shenk for their item drops, at the relevant difficulty. With most high level characters you build during the game, it is completely mindless and takes no effort to do, other than a few mouse clicks. I am sure similar examples exist in World of Warcraft. That's the crux of the matter I'm bringing up. Namely, what is the difference between a computer issuing the mouse and keyboard commands compared to a person for routine tasks, assuming they have the same knowledge of the game world without breaking the internal rules? I see none whatsoever for these tasks, thus this shouldn't be an issue.
Thus, the scenario WoW bots is not at all equivalent to deciding the next move in a game of chess. If there were bots that could intelligently play the game for you the whole time, making more intelligent decisions than a person would, this would be a different story. However, other than one done for Rogue, not many other bots exist. There are some in Nethack as well, but they are very much so a work in progress.

Re:Pop-Sci but well worth it...
Oh, I forgot - I wanted to comment on the rest of those books and add a couple.
Re: Griffiths books - they are both really good as intros to these topics (both are amongst my favorite "pleasure" reading physics books), but in the field they are often considered too elementary to be "serious," for better or worse. It's not that they are wrong, just that they are a little too user-friendly, which to me is a good thing.
If you can manage to wade through the extreme density that is that Shankar book, that should rectify things for QM - I have to say, though, I did not particularly enjoy that book, which surprised me since I adored his "Basic Training in Mathematics" book (likely too basic for a math major, I'd guess) and found him to be a fascinating lecturer (I never took one of his classes, but I occasionally slipped in and watched while between other classes). I think it's just too difficult to be so brutally thorough and remain interesting throughout an entire tome like that.
Jackson's E+M book is really the gold standard for classical E+M, though I'd really recommend hitting the literature if you're into stuff like self-action and all that.
Actually, I just noticed that the Griffith's recommendation was for his particles book, not QM, so scratch my QM comments - though if you find Shankar's book too weighty, pick up Griffith's QM book as a start, like most of his books it's very digestible (should take just a couple days to get through). If you find Griffith's particles book too light, which you hopefully will after a couple reads, you'll want some real field theory. The "standard" here is the Peskin/Schroeder book. That can be a little tough if you don't already know something about it; as a slightly more basic step in that direction, check out Zee's Quantum Field Theory in a Nutshell, which I was very pleasantly surprised with.
You'd also be remiss not to pick up something that Feynman has written on field theory, as I don't know that anyone else has understood it in as straightforward a manner as he has - there's always his various QED papers, which you MUST read all of, but as an astrophysicist, your thoughts will likely turn to gravity, in which case the often overlooked Feynman Lectures on Gravitation are definitely worth your time. Take the later chapters with a grain of salt, as some of the claims about stars are wrong; that said, his approach is quite interesting, and his approach to the Einstein equations is freaking amazing (he starts with a "bare" spin-2 theory, figures out how it's "wrong," and "fixes it up" until it "works," and lo and behold, Einstein's equations pop out of nowhere; those quotation marks hide all of the hard work required to get there, of course!).
Er, and also, I kind of hate to dump another 1000+ page monster of a book on your list, but as an astrophysicist you probably ought to read Misner/Thorne/Wheeler's Gravitation. It's great, though I can't promise it's just a few days work. The Wheeler stuff at the end is too speculative and flowery for my tastes, but the rest is pretty useful, and it's definitely worth keeping in your bookcase to intimidate anyone that might enter!
Robert Wald also has a great General Relativity book that might be less threatening; IMO, you should definitely own Wald and MTW. I'd suggest you avoid anything written by either Einstein or Dirac on the subject like the f***ing plague.

Re:More than one conclusion.
I'm with you on that. Evolution has more than one input or constraint. Even in the non-speaking animal world, communication occurs regularly. I find it difficult to surmise that because there is no record, it probably didn't happen. The development of many varied languages does not wholly support a sudden explosion of language, but a long history of developing communication methods. If it had started and caught on like some meme, it would look more or less alike all over the world despite local variations. It just doesn't seem to make sense that language could have arrived any other way than slowly with local variations vastly different from one another.. such as we see in the many languages spoken on the planet now. We see this even in the written word.
When the world was much larger (so to speak) assimilation of other cultures did not happen often or on the scales we see now, creating pockets of population that developed on their own-ish. This causes different needs for communication, and eventually different languages.
From http://www.trueorigin.org/language01.asp
By age four, most humans have developed an ability to communicate through oral language. By age six or seven, most humans can comprehend, as well as express, written thoughts.
In one short sentence, if the ability to speak/hear is innate in the human brain, then to say language only began abruptly 50,000 years ago is to say that the modern human brain really only developed abruptly 50,000 years ago. Forget the 10,000 year barrier some believe. Evolution is capable of many things, but I believe that the modern human brain was basically intact as we know it today before 50,000 years ago.
The paper at ftp://ftp.princeton.edu/pub/harnad/BBS/.WWW/bbs.donald.html also suggests that it's possible that what we think we know may not be true as there seems no direct evidence to support explosive changes in hominids at that 45,000-50,000 point, only fossil evidence of physical changes. It's a good guess, but still a guess. Communication happened from day one, when spoken language we might recognize as such began is nothing but a guess without some evidence of the actual brain structure or perhaps a nice wall painting of someone giving a speech?

Re:Security Concerns
You know I've posted this on
/. like three or four times now and you'd think it'd be more common knowledge by now... but getting encryption keys from RAM is pretty trivial. It's called a cold boot attack.
http://citp.princeton.edu/memory/
http://en.wikipedia.org/wiki/Cold_boot_attack
This attack was sort of one that was under the hat of pentesters and hobbyists until a few months ago when it was rather a do-it-yourself thing, but then McGrew Security made a followup PoC - http://mcgrewsecurity.com/projects/msramdmp/ to the Princeton paper. I played with it right after it came out, and then awhile later threw up a tutorial on remote-exploit. Now, Mati Aharoni's a really smart guy and most assuredly knew about the PoC before I did, but shortly after the tutorial and some discussion on IRC, it's now in BackTrack 3 (http://www.remote-exploit.org/backtrack.html) as a syslinux boot option putting the attack within the reach of everyone.
http://tourian.jchost.net/shadow/liveusb/boot.png
Getting the encryption keys out of the ram dump isn't a point and click operation, but the code's out there and it compiles. People are walking around right now with this on their USB key, and it's the sort of attack that is a real problem that physical access and untrusted users present now. Even without the encryption keys, you've still got the contents of previous webpages, cookies, IM conversations, unencrypted files, and everything else in RAM. Disabling boot from USB doesn't matter much because you can just use a grub CD, and carry around a laptop drive and do dumps on multiple machines. Hell, if you felt like dealing with it you could make it a PXE image... even disabling both boot from USB and CD, most cases in public places(think Dell) can be quickly popped open with the power still on and the BIOS jumper tripped.
Things like this should make you really nervous if you were freaking out about Microsoft's little COFEE ( http://tech.slashdot.org/article.pl?sid=08/04/29/1441215&from=rss ) toy, since it's no more impressive than a customized "Gonzor's Payload" U3 USB Drive ( http://wiki.gonzor228.com/index.php/SBConfig ) with a Microsoft Sticker and this is quite a bit more, well, dirty. -

Re:Interersing trend...
Except that oil consumption by refiners is largely inelastic. They can't just flip speculators the bird and tell them to take delivery of the oil themselves, because the price on the futures market is actually higher.
That's half of the equation--and a very important one. Demand for that oil is highly inelastic. But what is the elasticity of the supply? Assuming that your model of a speculator is one who cannot take delivery of the oil, then once you reach the spot market point where the contracts come due, the speculators' supply curve should be completely vertical. They have to dump the contracts at any price the equilibrium quantity dictates, and what's the quantity? The physical quantity of oil.
I wish I could draw graphs here, but I can't, so I'll try to describe what I'm thinking as best I can. Since we have a few outstanding posts in with each other, I'll put the relevant response here:
With a simple market direct from the producer to the consumer, you'll have your standard supply / demand curve pair making a nice X with an equilibrium quantity that results in all of the oil that was pumped being burned. If you take that supply curve and replace it with the vertical supply curve that a bunch of speculators generate on the spot market, you'll end up with an equilibrium that's dictated by the fact that Q stays the same. The only way to bump that price up is if Q is reduced.
I'm not sure what Krugman is getting on about with comparing the futures market to betting. He's right when he says placing a bet doesn't affect supply and demand, but the market isn't just betting.
His point has to do with that supply curve going vertical on the spot market. It's the discovery point at which all speculation is reconciled with reality--the fact that Q is fixed by physical reality and the demand curve hasn't moved. There's no question that the price of futures can jump all over the place as long as the people supplying those futures on the market have the option not to sell them.
The supply curve in that case can change shape and shift back and forth and drive P and Q all over the place without any change in demand. Once you get down to the spot market, those facts change if the suppliers are speculators. Once that happens, Q is no longer "number of oil futures" but rather "barrels of oil" and barring a shift in the demand curve, the only way to change the equilibrium price on the spot market is to change the amount of physical oil moving through the system.
Unless my analysis on that front is broken somehow, Krugman's model described here seems to be a good description of what happens.
I see what you're saying, and it makes intuitive sense, but I can't get the quantities to work out in a sensible model. I keep coming back to what seems obvious: Unless demand shifts, the only way to change the price is to change the supply curve and the equilibrium Q. How do you do that without changing the amount of oil pumped out of the ground or hoarded by the few entities that can afford to do so? -

Re:solved within 7hrs...
The date on the fax actually seems significant... TFA suggests that this was received by Fermilab just over a year ago, which was not long after the (very well publicized) Fermilab-manufactured quadropole triplet failure at the CERN Large Hadron Collider.
According to a 2006 Princeton Physics News article (page three of the PDF), Frank Shoemaker was a pioneer in using quadopole doublets to focus particle beams ... coincidence?
The timing seems suspect to me. -
