Sure. And for what you described, that works fine.

But now, what if instead of measuring both oreos on the same axis, we measure then on slightly different axes?

In particular, let C(a) be the correlation coefficient between the orientation of the oreo measured along the z axis and its orientation measured at an angle a to the z axis.

You can derive a limit on the correlation that can be seen between any two angles (a and b, assume for simplicity coplanar with the z axis) - assuming the state of each oreo is a function of local variables like its speed and axis of rotation:

|C(a) - C(b)| - C(b - a) <= 1

For example, if you pick a and b both = 0 (measure everything along the positibe z axis, like you do in your comment), then the left hand side is just
|(-1) - (-1)| - (-1) = 1,
i.e. the QM prediction for that is perfectly replicable by tasty, tasty oreos.

But here's the thing: quantum mechanics breaks that limit for some angles. E.g. try it with a = pi/3, b = 2pi/3. Left hand side comes out as 1.5.

Informally, the absolute best correlation between a and b you can get with oreos is perfect linear correlation - what the inequality above is = 1. But with QM, you get a sine wave!

So rotating oreos seem like a good analogy to entanglement at first, but it's misleading. Turns out, neither rotating oreos nor any other classical system of local hidden variables can actually replicate the results of entanglement in QM. That's (a simplified form of) what Bell proved.
You mean we need evidence to know that moving Go to GitHub would be against the interests of the Google Code people, and that they would protest such a move?

Being cautious is one thing, being a sucker for being too cautious is another.

In that spirit, I have a question. How heavy are the solar panels? If their weight is comparable to 40kg then it makes RTG more attractive.
Because it's not important. What is more important is that the First Science Sequence was finished. In a detailed report, you may find that the battery didn't last as much as they thought it did (perhaps because of the double landings Philae had to make, etc.), but a public-facing article is not the place for it.

Also, there are probably N things that didn't happen as they thought it did. It is better to mention the K important things (K << N), than the N unimportant things that they got wrong.

If Philae, for example, didn't land on the comet at all, then they would have announced something like this: "Philae took a drive-by of the comet 67 p, and has done in-air experiments that would be valuable for us".

>> ... in the process of building a new Des Moines, a tech hub in Silicon Prairie...

Every story that comes out about every city has a statement like this. We've had different cities across the country trying to become "the Silicon Valley of XYZ" for the last 15-20 years. Have any of them done it? Considering we're still calling the effort "the Silicon Valley of blah blah blah", I think not.

I used to live in Philadelphia. I now live in Washington D.C. I've spent a lot of time in Baltimore. I wouldn't want any of these places to change from what they are to the "Silicon Valley of the East Coast". They should stay Philadelphia, Baltimore, and DC.

Don't get me wrong, I'm sure the Valley is awesome. I've personally never been there. I hope it has its own culture that the people there are proud of and it's not trying to become "The NYC of California" or something like that. My complaint is that we get bludgeoned over the head with popular press talking about "diversity is good, we need to increase diversity", but it misses the biggest chunks of it when it's right in their face. There is still a lot of good left in local culture.

Hmm. Not really. But privacy still comes into data management and storage. Where you back up to and when and what protocal it uses, when you are recording/taking pictures of whose work in what room. I might be allowed to take all the pictures I like of my work, but I might not have permission to do the same of my co-workers. Or a picture of my coworker eating a sandwich in the wrong place in a lab, might open up a univeristy/lab to a lawsuit.

For example I think not everyone would like anyone in their lab (including vistors) being able to record their work without permission.

Not being able to adapt the code to ensure that these will be followed without people needing to think about it, is a weakness.
It's amazing how people who should know better demand proof of something obvious that's been written about so many times, just like how Fox News demands proof that Obama isn't secretly a Muslim. Or how people demand proof that goto is a Bad Thing™.

Interesting that they were investigating this ultra high speed technology in 2005. That means its likely to be a significant part of PRISM, etc.
Because in 60 years the OS got useless layers of abstractions when used as server OS with programming languages that come with batteries included.

If the programming language has a rich ecosystem with a runtime that is already taking care of hardware abstractions and scheduling, why replicate it a few times in lower layers?

How many schedulers or device drivers are needed to serve network requests?
You claim the second most important reason for using HTTPS is my privacy, yet you share all pages I visit with Google analytics.

As long as 90 percent of all websites keep using analytics, authorities only have to go to one place with their warrant to get more or less your complete surf history. And by adding SSL to your site you make things like Privoxy useless.

I think its strange no one has pointed this out in the SSL hysteria going on right now.
Private prisons? That's a nice touch! Out of curiosity, how does a private prison work? I mean the client is the state or say (if a con has money) I can do his time in private prison with a PS-4, regular medical examinations, internet access (probably monitored), etc.?

Not that it's bad to have civilized prisons, but I'm curious how a private prison operates.

> Now I can have a production-ready Node.js stack after 5 minutes on StackOverflow

The only 5 minute task that is likely to result in an actual "production ready" environment, is making/buying a cup of coffee.

This sums up my beef with what appears to be a reasonably popular interpretation of the term "dev ops".

People always claim that developers should have more hands-on involvement in managing servers.

In theory that's fine, but the problem is, they generally don't tend to appreciate that sysadmin/server management/call-it-what-you-will is not just 2 lines of shell commands copy-pasted from stack overflow.
It seems a case of intense bureaucratic / political pressure to change targets after they aren't met

Why would you need silicon for that? Even if it were the only process we use now (which it isn't. As a simple example, Germanium-based photo diodes do exist), materials research could conceivably produce other materials that work, too.

There are even more exotic examples to think of. Eyes turn light into electricity without (AFAIK) Silicon. Maybe part of that physics/chemistry can be practically used elsewhere?
While being so far that travel to SF is really inconvenient. Sacramento is not really being compared as "near enough to SF to count", but rather "A city in the US that is not SF", and thus is being compared against every other city that falls into that category. Being close enough that an hour and a half drive (assuming no traffic) and the expensive parking necessary to visit SF may be a point in its favor, but I'd imagine not a tremendous one.
Nah, government is the client. See http://en.wikipedia.org/wiki/Private_prison for details.

Of course, this system is very easy to game - in one scandal, judges were bribed by prison operators in order to send kids to jail for stuff like "mocking a principal on myspace". See http://en.wikipedia.org/wiki/Kids_for_cash_scandal for one of these.

Of course, putting kids in jail for stupid myspace comments will make them responsible adults cough...

I travel from Chicago to Des Moines several times a year to visit my parents, and have seen much of what the city has to offer. Restaurants, music, culture are all fantastic. The local craft beer scene is growing like crazy, and most taprooms have prime spots along popular bike trails throughout the city. I'd consider a fantastic city for biking. And between Ragbrai and the HyVee Tri every year I'm reminded of how awesome the bike scene is there.

The tech scene is like many other mid-sized cities in the Midwest: small, growing, but not ever close to the major tech hubs. If you're going to bootstrap a company and want to have a low cost of living it's not a horrible place to do so. Dwolla strikes me as a bit of an anomaly in the city, as most of Des Moines is insurance companies and agribusiness (which is no joke, especially if you like embedded programming and GPS).

You absolutely have to own a car, and in the past few years something resembling bad traffic has started to appear as the sprawl north and west of the city accelerates.

Des Moines is basically a better alternative to the other mid-sized cities like St. Louis, Indy, Columbus, Milwaukee, etc.
Disclaimer : I am an Android developer

The way I see it : nobody knows which technology is going to be prevalent in 5 years.
Android and iOS are now the two mobile platforms of choice and I don't see any of these two weaken significantly in the near term.

They have both kinda the same downside :
-Nobody uses obj-C / Swift outside of Apple bubble.
-Android is pretty much the only place where Java is not boring. Some net giants like Google also do very interesting things with it server side, but outside of these 2 cases, Java is a used to make mediocre software.

I don't think it should be up to your employer to decide for you which technology you should learn, but that's between you and him.

As far as I can tell, neither iOS, nor Android is a bad choice. in the mid/long term, you might want to have a look at the new cools kids on the block, Rust, Dart and Go.
It's more interesting that physical location matters at all in 2014.
If looking for a city sized similarly to Des Moines, check out Grand Rapids, MI. Lots of great art, craft brews (Founders Brewing anyone?), and a small startup scene. You're also a 30 minute drive to Lake Michigan in the summer, which is nice when its warm enough to experience it :)

Yes, the client would be the US government or state. Private prisons hold about 8% of prisoners in the US, during 2013 the number of prisoners in private facilities declined by 3%.

Numbers from here:

http://www.bjs.gov/content/pub/ascii/p13.txt

There are some other problems with perverse incentives in the US incarceration system (businesses are allowed to employ prisoners at low wages), but the "it's all about private prisons" narrative isn't really backed up by the numbers.

If you look at the sort of crimes that people end up getting put into prison for, at least statistically, they aren't Myspace comments.
I think you're quoting me out of context here. I am debating the consistency angle. My argument is that if there is such a drive for consistency (and therefore that's a good reason to keep the braces) then the method syntax wouldn't have changed to drop the braces. So I feel that argument is moot when discussing the reason for keeping the (what I believe to be) ugly syntax of X { get; } = 5;

Your example of the computed properties is not the same. I like the computed properties syntax, but unless the properties can be computed from the constructor parameters then you will still need to either use the ugly property syntax, or readonly fields to get the same immutable guarantees.

Personally I am fine with using readonly fields, I was only commenting on how the C# team have (in my opinion) missed the opportunity to get rid of some of the unnecessary clutter. I know however many people don't like using readonly fields for various reasons: serialisation, data-binding, interface declarations, etc.

The beginning of the Holocene around 11700 BP might serve as a good objective reference point. Nearly every interesting thing that happened in the history of human civilization took place in the Holocene. No more negative years to worry about!

"Present" in "before present" (BP) usually means 1950 AD [1], so this year would be Year 11764 of the Holocene epoch. Brb, gotta find some COBOL programmers to fix that Y10K problem.

But then, the starting date of 11700 BP is also kinda arbitrary. No single short-term event defines the boundary between Pleistocene and Holocene, so we're still left with a sizable margin of error, probably even larger than the error in Jesus' date of birth.

The biggest disadvantage is their performance because it's hard to make them do operations in parallel.
A lot of the usual criticisms don't apply. This code will never be JIT-compiled. Instructions take either 1 or 2 cycles depending on whether memory is accessed, so there's no pipelining or caching concerns.

Actually in this thing the top two elements of the stack are held in registers. So if you wanted to use the ANSI C compiler instead of FORTH, you might just think of it as a two-register machine (there are actually quite a few more) with a few special stack-manipulation instructions.
As Developers Depart, Google Glass Is Ready to Become This Era’s Segway
As a Brit, pretty much all I know of Des Moines is what I've learned from Bill Bryson, the first line of his book "Travels in Small-Town America" is "I come from Des Moines. Somebody had to."
It's disappointing that this is the most upvoted comment in this thread. The mission was a success and will enable the scientists to understand much more about the whole thing. Plus, the orbiter will continue to track the comet and there is a chance the lander will come back from hibernation mode once there is more sunlight available.

I think people in general have come to expect the incredible lifetime of the Mars landers as the norm. It's not.

But since this is HN, I'm sure we all in the IT world are pretty confident in our estimations and our projects are a complete success all the time. Might explain why we are so disappointed with ESA. </sarcasm>

Mostly drug-related stuff, especially victimless crimes such as pure possession without intent to distribute... while Myspace or other cyberbullying can certainly be jail-worthy, a shitload of US prisoners are in for drugs.

imho, the US and every other country in this world should end the "War on Drugs". It has undeniably failed, and costs taxpayers everywhere billions of dollars, in addition to the hundreds of thousands of lives lost alone in Mexico...

Theoretically you can make integrated circuit with any semiconductor, but I don't know if anyone has been brave enough to try it.

The smallest integrated circuit is a diode, it has 1/2 transistors :). OK, a diode is not actually an integrated circuit, but if you can use a material to make a diode, you probably can use the same material to make an integrated circuit with enough money, time and ingenuity.

Some of the diodes are made of germanium. It has a very low band gap, that is useful for "crystal radios" ( http://en.wikipedia.org/wiki/Crystal_radio#Crystal_detector ). Perhaps this can be useful to make very low voltage CI, to reduce the power and heat. But perhaps there is a technical problem that I don't know.

The diodes in the LED have many semiconductors. The band gap of the material is related to the color ( http://en.wikipedia.org/wiki/Light-emitting_diode#Colors_and... ). With this you could make high voltage CI (like 10V?). Perhaps it may reduce the noise ratio??? But perhaps there is a technical problem that I don't know.

[kens: If you are reading this, I'd love to see a technical post about this subject.]

--

Edit: According to Wikipedia, one of the first CI was made of Germanium: http://en.wikipedia.org/wiki/Integrated_circuit#Invention

> Half a year after Kilby, Robert Noyce at Fairchild Semiconductor developed his own idea of an integrated circuit that solved many practical problems Kilby's had not. Noyce's design was made of silicon, whereas Kilby's chip was made of germanium. Noyce credited Kurt Lehovec of Sprague Electric for the principle of p–n junction isolation caused by the action of a biased p–n junction (the diode) as a key concept behind the IC.

Either I am failing to grasp what you are saying or you are completely naive about the humongous risk involved in cutting edge science of any kind.

This ain't some piddly kickstarter trinket. And exactly what was promised that you didn't get your money's worth for?

Speaking as a researcher in the biological sciences, funded by public tax-payer sources only (don't forget, I also pay taxes), the risk of failure is absolutely astronomical with every project I have ever undertaken. The fact that those projects have succeeded the way they did, is, at least in my mind, phenomenal. Even then, none of these projects, or any projects of any other scientist in my field, have ever achieved all their stated goals.

If this rankles you, move to a place without public funding of science and bet your money on trinkets put up on kickstarter. Or if they are not trinkets, but are true attempts at solving hard problems(curing HIV/cancer, landing on a comet), I hereby guarantee that none of them will succeed 100% of their stated targets.

I find it interesting that the interviewer almost calls out on the disappointing fact that the surface smoothness is essentially just "blobized" interpolation: "It doesn't seem very subtle." It's like when a director has run the film through some colorizing filter to give it a desired tone and you can tell to the point of it becoming distracting.

What if we compute the value of a person life at a certain age as the difference between the life expectancy and his age. Then ten very old people could be less valuable than one child? That axiom is sound and your claim doesn't hold.
The weight of solar cells used on the Earth comes from making them protected from the environment, the material that produces the power itself is very thin.

http://sbir.gsfc.nasa.gov/SBIR/successes/ss/3-027text.html

Note "1 kW/kg" specification but it's probably in the Earth's orbit, using the inverse square law, it should be an order of magnitude less where Philae now is. Still, it appears it can remain quite light to have 2 m^2 of cells there.

Anybody has more exact details for the weight of the cells on Philae?

I am from Chicago, but went to school at Grinnell. We used to drive alternately to Des Moines or Iowa City on weekends for something different. I preferred Iowa City, but Des Moines was great too.

Anyway, my point is that the state of Iowa is this beautiful, underrated and amazing place. I have lived in a lot of places since graduating and have lived abroad for the past several years now. But, if I ever did go back State-side, I would probably try to find a job in either Iowa City or Des Moines. They are both lovely cities, for all of the reasons mentioned in this video.
