Question about returning documents: OP stated these are printouts, so what is the point of returning them if the original owner can just print them out again? Wouldn't returning the documents actually put that person in trouble, because their superior will know this information was misplaced - or is it the point to notify superiors?

Cryptographic hashes are an entire category of hash functions unto themselves. The absolute minimum guarantee that a cryptographic hash makes is that for any polynomial time algorithm, the probability of the algorithm computing a pair (x,y) such that x != y and H(x) = H(y) is "negligible" i.e. is smaller than 1/p(n) for all polynomials p and large enough n; in other words, cryptographic hashes guarantee that collisions are extremely rare. Much like you can create a cipher with security that is reducible to the hardness of some problem (e.g. ElGamal is secure if the Diffie-Hellman problem is hard), it is possible to create collision resistant hashes with such security proofs, e.g. Very Smooth Hash, SWIFFT. In practice, though, we just use hashes that are believed to be security according to heuristic tests; hence the need to periodically update standard hash functions, rather than to just increase parameter sizes.

Also interesting is universal hashing, which has applicability in cryptography (for randomness extraction, among other things):

It would be just too good for developers not to worry during development. We can avoid loading extra scripts and stylesheets just for this. Just a thought and would like to hear comments on this.
>I find memory management a pain without RAII,

That statement is true. But, as you may be aware, it doesn't encompass quite a few use-cases. A lot of usecases require you to have fine control over performance and using RAII will cause random speed-bumps. for e.g. when a ref-counted smart pointer(s) goes out of scope and triggers 'heavy' destructors on held objects to free up resources - at a non-deterministic time.

"Confidence" is not really an economic variable, nor does it magically evaporate. Go through that list of countries; filter out all those where:

- it's a very poor third world country (Angola, Zaire, Zimbabwe etc)

- countries coming out of Communism (all the 1992 events) or other revolution (revolutionary France)

- hyperinflations triggered by war (Germany, Greece etc)

- those predating a 20th century understanding of economics

You're basically left with South America, which is somewhat exceptional and has a strong connection with the tendancy for revolutions, coups, US interference etc to trigger crises there.

US inflation, meanwhile, ticks over at a few percent and is resolutely stable, despite the best efforts of the House to trigger a crisis.
What he doesn't emphasize is the directionality of this phase transition. It's really easy to add one more string, but staring at the resulting button-thread agglomeration it's very difficult to know what string to cut.

Like it or not, the term social science is widely used, understood and accepted in the English language. Everybody knows what it means and understand that it's not the same as physical science.
From my experience code is either 'done properly' or 'shoehorned in'. But really, 'done properly' means 'you have time to organize everything satisfactorily at a high level', typically only when you are writing a new module from scratch.

Everything else is trying to shoehorn something new into an existing framework, and you don't have enough time to get it 'done properly' because your product manager has a heart attack when you tell them how long it'll take to do a proper refactoring job. This is where you will quite happily cut corners, and the chance that you'll inadvertently break existing functionality in the process increases exponentially. This is the mechanism that, in my experience, causes balls-of-mud.

And of course, no matter how good you are at planning every required use-case of your code over its lifetime at the 'done properly' stage, you can never think of it all, so at some point or another you are forced to shoehorn stuff in everywhere anyway.

If the goal is to heat up the reserve tanks as quickly as possible, I would think so, else I guess the plant can simply divert some of the heated oil from the water boiler to the tanks and slowly heat them while the sun is shining.

I don't think the plant needs to warm up that long before it can produce energy, since only the oil between the collectors and steam generators has to be heated.
I believe salt is used for thermal storage, but oil is the heat transfer fluid used to generate steam.

solar -> oil -> steam || salt

Would the security of such algorithms improve dramatically if say 5 years from now we'd live in a world where everyone has a 64-bit device or machine, and the algorithms can be optimized for 64-bit? Are current algorithms limited by 32-bit a lot or not really?
That's true, but I'm unaware of much work being done on the error bounds for small N (for some concept of small). I started on this during my PhD, but rapidly moved onto other problems that seemed more tractable, and never really returned to it. The results of Bollobás, Erdős, Rényi, and others, are mostly asymptotic. They do, however, seem remarkably good even on graphs of small size (under 10^6 vertices).
10 steps is way to long. Also, why are they including nginx? Is it a requirement of the host?

Bitcoin uses a cryptographic hash function, SHA256. There are, at present, no known collisions with SHA256.

This question is about non-cryptographic hash functions, as are commonly used in hash tables[1] which implement associative arrays, or sharding databases based on the hash of the record key.

Non-cryptographic hash functions are simply not in the same league as cryptographic ones; cryptographic hash functions are optimized to make it infeasible for an attacker to generate a different message with the same hash, while a non-cryptographic hash function generally simply has to have uniformly random output over its keyspace.

These are 32-bit hashes. 160-bit hashes with similar characteristics are outrageously less likely to generate collisions. Something like 3.4 X 10^38 less likely if I'm running ColinWright's formula properly.

That difference is computationally extremely significant. It took the SO poster ~9ms to find a collision with, e.g., Murmur. If you mapped those results to the 160-bit hash, finding a collision, even ignoring the added time to compute the larger hash, would take 97 octillion years.

Well, the first problem is its not true, or at least badly out of date. The UAW is close to gaining control of Chrysler aka over 50% ownership. Sounds insane, yet its true. Also I think UAW is a hair under 20% stock ownership of GM at this time. Of course there are innumerable smaller unions who own no stock and pretty much have no assets on the balance sheet, which at least makes them judgment proof if nothing else. Another problems is the concept of the local electricians union owning stock in a sole proprietorship small industry where one union card carrying industrial maint electrician works part time, and spends the rest of this time freelancing at residential small jobs, doesn't even make sense.

The fundamental problem is you really can't have two masters. So you work to optimize your stock profits; or employees? You might have to screw over some employees to boost the stock price to pay for health insurance for the retirees? So you want to move into Toyota plants but honestly, frankly, the best thing you could possibly do financially for your GM stock ownership would be to completely screw up the Toyota plant IF you moved in? Are you a non-diversified mutual fund representing the financial security of retirees, or a labor union representing the desires of the workers, or as a major owner you are by definition management representing the interests of management? If unions start owning lots of stock, who exactly is representing who and when? The game is a lot simpler if each player only has one master.

You could probably make an interesting startup game and/or cardboard eurogame of the whole crazy situation where multiple player factions represent multiple other player factions but you never really know who's representing who at what time as the game progresses.

Agreed. WordPress is hardly difficult to extend or build for.
The length of the digest is 32 bits in the linked example and for Bitcoin is 160 bits. Assuming the hash functions are good, if you only have 32 bits of output you can expect to find a collision after 77,000 hashes; the examples used three times that! With 160 bits, you need to generate many orders of magnitude more hashes before a collision is likely.

"An observational science is a science where it is not possible to construct controlled experiments in the area under study. For example, in astronomy, it is not possible to create or manipulate stars or galaxies in order to observe what happens. Other examples of necessarily observational sciences include geology, paleontology, epidemiology, and much of the social sciences."
Phone polling and telemarketing need to be opt-in over the telephone network, regardless of your connection type (landline, cellular, VoIP). There should also be a class of service where the caller pays for not only their part of the call but the costs the called party incurs when they are called. Then telemarketers and pollsters should be forced to use that method.
Eventually you'll be able to their hosted service, but for now when you register you just get access to a source download for self-hosting and access to their forums.

Yeah, the US has the massive advantage of being the world's reserve currency (for now). As such they can EXPORT inflation. Se the Wall Street Journal: The Latest American Export: Inflation

What do the years 1971, 2003 and 2010 have in common? In each year, low U.S. interest rates and the expectation of dollar depreciation led to massive "hot" money outflows from the U.S. and world-wide inflation. And in all three cases, foreign central banks intervened heavily to buy dollars to prevent their currencies from appreciating.

When central banks issue base money to buy dollars, domestic interest rates are forced down and domestic inflationary pressure is generated. Primary commodity prices go up quickly because speculators can easily bid for long positions in organized commodity futures markets when interest rates are low.

The world saw a surge in the dollar prices of primary commodity prices in 1971-73 following the Nixon shock of 1971 when the U.S. abandoned the gold standard. There was also a commodity price surge during the Greenspan-Bernanke shock of 2003-04, when the federal-funds rate was reduced to an unprecedented low of 1% followed by a falling dollar.

A little bit of the riot happened within a small part of the shopping area of Croydon town centre, constrained to about half a square mile or so, apart from one or two stores in the Purley Way retail park. The Reeves corner store burning down was the "highlight" yes, and a couple of stores had some broken glass.

I walked through the town centre on the days of the riots, and frankly it was mostly quiet and uneventful - the media coverage was massively overblown.

No. To be honest, I was a bit baffled by your question: why would you think that it would take the same time to heat as to cool?

It will heat depending on how quickly you can get energy to it, and it will cool depending on how quickly you can remove energy from it. Have you never seen an electric heater or oven and noticed they heat quickly and take a while to cool down? Or rapidly cooled something by putting it in iced water or a freezer?

From the sounds of the article (paper is blocked) it appears that what's actually being tested is the ability of people to read the thoughts of fictional or portrayed characters.

> For example, folks who were assigned to read highbrow literary works did better on a test called "Reading the Mind in the Eyes," which required them to look at black-and-white photographs of actors' eyes and decide what emotion the actors were expressing.

A running joke in some acting circles is to sit down with a fellow actor and give them emotions to try and "emote". It becomes a joke because the emotions that are thrown out quickly become hard to even understand let alone interpret into a face. "pensive anticipatory surprise!" "respectful despair!"

The problem with this is that it tests for the ability of an audience to "read" a fictional character, but not necessarily a real one.

For example: this http://images.sciencedaily.com/2009/10/091031002319-large.jp... is an actor making an angry face. How many people here know someone real who's face becomes absolutely calm when they are in the heat of rage?

Authors have no greater insight into people's psychologies than anybody else, but they can construct a character that, when well motivated, has a representational psychology that can drive a story.

However, various factors make this hard in many cases as certain, close to real, believable characters really require the author to, in some sense, "be" that character in order to represent that character's thought processes. This frequently falls down in certain cross-representations. For example, cross-gender representations are frequently very flat: women written by women tend to have full and complex inner worlds while their men tend to be flat archetypes and visa-versa.

Really good authors get praise for writing cross-representational characters well and the best authors simply try and avoid it through clever story construction (unfamiliar cross-characters are turned into flat background players, or they're turned into crazy people where their madness creates an unpredictable inner-drive that covers up for the authors lack of knowledge). What was the last book anybody read, written by a White American privileged male author that explored the inner psychology of a Black inner-city French teen girl?

You'll notice that children are also as terribly written as they are painted in Renaissance paintings.

http://uglyrenaissancebabies.tumblr.com/

It's not that the author never lived as a child, but that as children, we don't have the faculty and level of self-awareness to record what it's like to be a child in most cases.

More importantly, emotional display is often very cultural. Can anybody tell me what this emotion is?

In New Jersey it is illegal for you to fill up the gas on your own. It has to be done by the pump attendant. That's the law. Not sure about Boston ;-) It might be that it makes business sense for the owner to have pump attendant at the rate or above of the minimal wage. Which is nice.
Okay so it's like international waters. That doesn't mean that there are no laws there. And the agents -- who work for the US government -- must still obey the laws of the US government, no? And despite it technically not being "regular" US soil the laws of the US still apply don't they?

Otherwise if it's truly a no-man's land I could take a plane trip with another person who I intend to kill, depart the plane and while still in the border control area kill him in cold blood in full sight of everyone there. The US might want to prosecute me, but they technically can't because the law doesn't apply there.
