It could also be fuzzy!

In combinatorial game theory, the star game is fuzzy with zero: not less or greater, but not equal either.

The zero game is (iirc) the game where neither the left nor the right player have any moves, so whoever's turn it is loses.

The star game (*) is iirc the game where both players have the move to move to the zero game, so whoever starts wins.

But the star game is fuzzy with the zero game, less than the 1 game, and more than the -1 game.

Hmm, that's a good point. Oppenheimer had much more to lose with his clearance/position and far more baggage they eventually used against him than Feynman (aside from some extremely personal vendettas against Oppenheimer). Maybe it was plausible after all, since Oppenheimer was known to encourage his colleagues to do what they thought was right.

Guessing if comparing the two, it would hurt Oppenheimer's rep more than someone like Feynman, since they blamed Oppenheimer more than anyone when many of the Manhattan Project scientists refused to work on the H-Bomb project with Edward Teller.

I have always thought that development should be something like this. The only thing you need to resolve is how to handle proprietary source code.

Oh and also what if everyone doesn't want to code in ocaml?

I think we need something similar but built on a type of ontology or description logics or something that represents the program in a common way that is not tied to a particular language representation or model. So I would start with research that does automated program generation in Ocaml and create a semantic model of those concepts.

You want to convert the functions from mirageos into this common knowledge representation in a way that integrates with the program generation ontology.

You then want to create a projectional editing system which allows for different representations including but not limited to ocaml.
Predicting A Future Free Of Dollar Bills
I come from "the low lands" in Europe, and trust me when I say this : it took two major disasters to make people redesign the water infrastructure. This occurred in the Netherlands in 1954, and was what created "Rijkswaterstaat" [2] (this is a Dutch ministry, and they're serious assholes to be frank, but without them ...), and the development of the "Delta works" [3].

Incidentally, apparently they won't even be maintained without a major disaster. It's now 2014 and a project to raise the Delta works was scrapped for the funds, which will go to some bank related measure instead (the dykes that form the Delta works are sinking into the ground due to their weight and should be raised to avoid the risk of water spilling over them : if the conditions of 1954 repeat, currently a disaster of about 1/3 the proportion of the 1954 floods would occur. It gets worse every year, and apparently by 2065 the Delta works will no longer provide any defense at all, meaning yearly flooding disasters will start occurring at that point).

Just providing a data point. Sea level rise is not a significant factor for the delta works (rather the standard deviation in average sea level is. In and around the channel there is an average sea level, and you see sea levels up to 6 meters higher than the average in most locations once per decade. A few centimeters don't really change the calculation. Hell, even a meter wouldn't significantly alter the situation. But the dykes are just barely 5.5 meters high anymore, and will fail entirely if water starts spilling over. Meaning once the water level goes more than 10 centimers or so above the top of the dykes, they will most likely fall over. Average sea level rise creates a problem for ground water, but that won't really affect anyone for quite some time. Btw: go to the page of the delta works linked below. Look at those towers. Just think of how much tonnes of water these guys are keeping out, yet those towers, impressive as they are, will fall over (more likely torn to shreds, but ...) in the next decade or two if nothing is done)

In general, I'd look at the Delta works though as an example of how everything can be fixed, but it comes down to this simple fact, and environmentalists won't like it. Humans need to take direct control of the ground water table, by erecting concrete barriers that make it look like the sea level drops several meters from the perspective of inland water tables. Those barriers can also prevent flooding by providing a large coastal basin of water where levels are maintained much lower than sea level (by opening the dykes at ebb and closing them at flood times), where storm floods can drain into. This will destroy fauna that depends on being exposed to waves (I'm sure they can be maintained in a few locations, like "Het Zwin" [1], but they'll no longer dominate the coastline), and will be replaced by inland river-fauna (frankly, I like that much better, but again, environmentalists will object to what amounts to artificial habitats).

Parents of nerds sometimes get worried like that. Which is also a 'self-determination' type issue just as much as raucous behaviour.
You've got to wonder why global warming is dragged into this. The city cannot possibly hope to do anything about that, even if it wanted to.

Obviously the solution is dykes, and better water infrastructure.

Ironically I'm betting the environmentalists will oppose that.
Instead of calling the 'else' condition of the for loop a 'completion-else', just call it the 'nobreak' condition. Unlike 'completion-else', 'nobreak' immediately describes when it will be executed.
Yeah, the compiler typically assumes it works, and encodes assumptions that it does work into the surrounding code. On some systems you will get SIGFPE. On other systems, the result is something defined like 0. On some systems, the result is whatever happened to be in some register or whatever.
McDonalds had been warned about servig their coffee so hot; they had previously settled suits from hot coffee; they were serving coffee hotter than their rivals.

> Python guesses the system encoding using logic that looks at the locale environment variables

This is not an implementation detail, but means that when Python chooses a different encoding than you thought, your program crashes spectacularly (and not on start, but on some unicode operation further down the line).

The same program will run differently depending on who starts it. This should go on top on all Python 3 tutorials, since it's not obvious at all what happened, especially not for a beginner. Non-conformant environment variables and file names causes all sorts of weird problems.

I can recommend Armin Ronacher's unicode tutorials for Python 3. It is what saved my sanity when I first encountered it.
When I read "cores" I think "on the same chip," so that took some re-reading to parse. Handling the radio is the job of the baseband processor, which has its own RAM and firmware, in a separate package from the CPU. It looks like, as of the iPhone 5s, it's still a separate processor. I think that the vagaries of FCC licensing will keep it separate; otherwise, you'd have to re-test it for interference whenever you rev'ed your CPU or perhaps even firmware. I think most baseband firmware is proprietary and tightly controlled; for the paranoid, it presents an attack surface that's very hard to examine.
You say McDonalds overheated the coffee, but the wiki page you linked to says that is a normal temperature, McDonalds still brews in that range, and Starbucks brews in that range.

Since Liebeck, McDonald's has not reduced the service temperature of its coffee. McDonald's policy today is to serve coffee between 80–90 °C (176–194 °F),[28] relying on more sternly-worded warnings on cups made of rigid foam to avoid future liability, though it continues to face lawsuits over hot coffee.[28][29] The Specialty Coffee Association supports improved packaging methods rather than lowering the temperature at which coffee is served. The association has successfully aided the defense of subsequent coffee burn cases.[30] Similarly, as of 2004, Starbucks sells coffee at 175–185 °F (79–85 °C), and the executive director of the Specialty Coffee Association of America reported that the standard serving temperature is 160–185 °F (71–85 °C). Retailers today sell coffee as hot or hotter than the coffee that burned Stella Liebeck.

The National Coffee Association also suggest 195-205F.

Not even the same ballpark. Releasing the total revenue and costs for a quarter is nothing like releasing the price each client paid.
Take into account that "during school hours" and "on school grounds" is a much bigger chunk of kids' lives in the US than it is in most other countries.

In most countries, school is just the place where you have lessons for a few hours, and all other activities, including even lunch breaks, are part of kids' private lives outside of school and outside of school grounds.

Add to that no school buses and no parents driving their kids to and from school in SUV's, and you get a culture in which kids have a considerably chunk of private life outside of either parental or school control.

The problem imho is giving school administrations so much influence and authority over kids in the first place.
its beautiful, however even the rather static looking "sports" page produces some decent CPU load and makes the fans in my rMBP spin up. Maybe that could be optimized :)
What the article misses, though a few commenters pick it up, is that this discounting is also a form of price discrimination to maximize profits. The institution will charge each customer based on their willingness (ability) to pay. The schools are actually in a great position to do this because of the fine granularity of the grant amounts and the willingness of their customers to divulge their willingness to pay.

A counterbalance to this though is that bright students are as much the product as they are the customers, especially in elite schools, where building up networks is a key driver of demand.
In the very early 90s I put a fake virus on the library computer as a prank. The "virus" was in-memory only and would disappear on reboot. It mimicked the real DOS virus that caused letters to start to drip down from the screen. I was contacted as the resident "computer expert" to come in and fix it. In retrospect I realize two things: 1. This virus was probably the inspirations for the Matrix lettering effect. 2. The school must have known it was me that installed that shit on their computers.
No, this is wrong.

In order to work with infinitesimals in any reasonable way, you have to define how they work. There is a reasonable way to extend the real numbers in a larger field containing infinitesimals. Such a field is non-Archimedean and has very surprising properties: for example, you can construct a geometry in which Euclid's fifth postulate is false, and yet the angles on a triangle still always add up to 180. These fields also allow you to formalize your intuition about the way infinitesimals like "dx" and "dy" in calculus and analysis work: you can take an equation and multiply both sides by dx, for example. This is ordinarily meaningless, since the term dy/dx is ordinarily just notation that does not actually signify a fraction. In non-standard analysis, it IS a fraction. I think it's a shame that analysis classes in college don't use non-Archimedean fields because the proofs are so much simpler.

However, even in these fields which admit infinitesimals, there is no definition for x/0. You can prove it for yourself.

Suppose x = 10/0.

0*x = 10
(0+0)*x = 10
0*x + 0*x = 10
10 + 10 = 10
20 = 10

So this is just an all-around bad idea, because it permits us to say that 10 = 20. And all we had to say that 10/0 had a value... we didn't even say what that value was.

P.S. Although infinitesimals exist, non-standard analysis still does not permit you to, say, plug ∞ into an equation, because there are many different infinite numbers. However, other systems (projective geometry) admit ∞ as a value.
I actually did that on purpose, and then immediately commented on the submission with a link to a page that contains the paper and supplemental data.

The reason I preferred to post the press release was simply because it explains the significance of the study and gives a little history, something that might not be obvious if I simply linked to the paper directly.

Unfortunately, my comment wasn't seen by many :-(. It would've been nice if one could post some supplementary text when submitting a link.
"A higher share of college graduates also yielded higher wages for workers without college degrees, likely because employers have to pay them more to keep them in higher-cost cities:"

I'm wondering if the increase in average wage of non-college degree holders outweighed the higher cost of living in the cities with high concentrations of college degree holders.

If so, not so bad, all boats lifted higher by the tide &c. I suspect that the rise does not outweigh the increased cost of living, especially rents/housing costs. The result is a long commute added onto the day for the people who do not hold college degrees and who work in the chi-chi economy. That process has limits.

Perhaps it needs a generation or two to reach steady-state?
I don't think it's reasonable to assume it was just 80% the seller's fault, however. Dealing with hot liquids can be dangerous, yes. But you need a good portion of bad luck to suffer burns serious enough to require surgery simply because there's just not that much coffee in a cup (indeed, its conceivable she would have healed without surgery, albeit with more scarring).

That's not to say the seller is faultless - but the verdict still strikes me as entirely disproportionate. Then again, that's the norm nowadays, isn't it?

Right, but the linked articles actually state that the main cause in reduced mortality was reduced traffic accidents. Almost all of the things in the NYT article would not have qualified as traffic accidents. On the face of it, this doesn't really surprise me: many things are "dangerous" yet it's not that easy to kill someone (or yourself) in an accident. Heavy machinery changes that equation, and virtually all heavy machinery we come in contact with are motor vehicles.

In other words: the data doesn't immediately suggest that increased caution has lead to reduced mortality outside of traffic. The NYT article is still plausible from this perspective.
How does this qualify as a "clever product hack"?

No, because proof-of-work prevents you from "faking" a blockchain. Let's say we are at block 100 and you would want to fake "the blockchain". You would have to fake a block every 10 minutes, but that requires mining, because you can't just make a block - it has to fit the previous one with the right difficulty.

You could stop sending new blocks, but that would alarm the endpoint because it will be stuck at block 100 (in our example).

The Proof-of-work scheme is pretty innovative.
The blockchain can be pruned.
Without surgery there is a significant risk she would have died.

I understand people get stuck on the 'coffee' aspect, but many acids cause similar levels of tissue damage. There is a huge difference between water at 140f and 190f.

To put things in perspective an autoclave at 134 °C for three minutes is as effective as 121 °C for 15 minutes. Steam at 134 °C can achieve in three minutes the same sterility that hot air at 160 °C can take two hours to achieve. Granted, 249.8F = 121 C, but water can transfer a lot of heat vary quickly.
You can catch exceptions
That would require trust - in the form of the SMS provider. No way to verify that SMS is valid, it could have been forged.
