Nice. Never heard of that.

Honestly, though, I don't think such a thing is what this website is aiming at. It seems to be more for the established, widely used stuff.

Still nice, though. (It's cute how, for so many of the "heap" data structures, the merge operation is really all you need to give much thought to. See also Binomial Heap, etc.)

> These 6 lines of code provide a heap data structure with amortized logarithmic time for extractmin and constant time insertion and merging (!).

Hmmm ... maybe. We need to be exceptionally careful in our reasoning about time complexity, when the code uses lazy evaluation (perhaps more careful than people know how to be, yet).
I don't consider myself a libertarian by any stretch, but isn't their argument in favor of a completely free market? If so, any government regulations that protect these de facto monopolies would not be supported either, as they are by definition creating a regulated market.
"In" doesn't necessarily lend itself to snappy English phrases like "to" does. It might also be confused with the gerund, especially when spoken - do I go to meet.in or meet.ing? And what's your company/product called?

And are there additional restrictions on Indian domains? Not sure. For example, last time I checked, only Americans could register .us domains.

Now that we're talking about big telescopes I can mention LOFAR: http://en.wikipedia.org/wiki/LOFAR

It's interesting in that it consists of 15.000 small antennas and they are using computers to combine the signals which effectively gives you a 1 square kilometer "dish".

Clear, concise explanations. Good job.

A tip: It would be better if you could expand on the "Real World" section, especially when it comes to specific examples (e.g. dictionaries etc). That way, more students would relate to understanding exactly how those data structures are used in practical applications.

That doesn't sound like any history of the modern university I've read. I don't doubt that some universities grew out of private tutoring from the wealthy, but the bulk of the western university tradition grew out of theology schools, whose students included quite a lot of the middle class.

I mean, Erasmus is one main starting point of the humanist tradition, and it would be difficult to characterize him as a wealthy kid hanging out in fashionable cities attending private seminars.

The wealthy were able to avoid having their kids attend such institutions precisely because they could hire private tutors! Either that, or they would attend only pro-forma, essentially buying a degree.

While I would never have called YC the new grad school myself, I think you have a mistakenly utopian view of the origins of western higher education. The "traditional" idea of a liberal education you're describing is largely a creation of the late eighteenth and nineteenth centuries. Originally higher education was about training priests, lawyers, and doctors.

As learning became more prestigious, rich kids started going to universities as well. They were not there for vocational training. But they were the newcomers. The original model of university student was the one Westfall described in his excellent biography of Newton: "a plodding group, narrowly vocational in outlook, lower-class youths grimly intent on ecclesiastical preferment as the means to advancement."

If anyone wants to learn more about the origins of universities, I'd recommend Haskins's Rise of the Universities.
I suppose they're trying to limit Chinese technological competition, and to delay Iran's getting long-range missiles (to choose two examples).

Legal solutions like ITAR are always coarse-grained, and the whole thing ends up looking silly because parts of it are silly.
I've had a change to play with it for about 2 minutes recently and now, after reading this review, I'd absolutely love to have it. If only I had the cash ... Well I could probably afford it, but then I'd want to upgrade my Bold 9000 too, and that would amount to some serious shortage in my wallet :)

I'm really happy for RIM (as this looks like an awesome product), everybody is "picking" on them and basically putting them into a grave. I really hope PlayBook turns this trend around a little and they return to their former glory.

I pay $15 / year for no-ip (they're a reseller) because they have good service. I'm glad to pay the difference.

Of course, one way they get away with a higher price is that they primarily sell DNS services. So it may be more expensive to pay with them, but it's also more convenient to have them handle both DNS and registration. (though I currently use their free domain service for some of those domains).
Bullshit. I've been right through from my bachelors to ph.d. without paying a single dime. Academia is full of smart kids on full rides.
I think the whole point of this experiment is to try out a new and cool piece of tech that might not be supported across the browser spectrum just yet but it doesn't mean that it won't be ever.

The point isn't so much whether or not Google comes out bad, it's whether you have someone to talk to that can actually fix the problem when something happens.

The theology schools were there first, but understandably they didn't teach much outside of ... theology. Kids with rich parents could do the Grand Tour of the continent and often visited famous thinkers where they lived. Around these sites universities often followed; eventually the idea of the university as an institution rather than happenstance evolved later.

(edit: I'm absolutely hand-waving a lot here, so I am prepared to be corrected)
Fair question.

- Hiding comment scores prevents bias. I get a chance to fairly read at
your contribution as it is without ever being biased by the opinions of
others. If you you're curious about cognitive biases, there's a good
list on wikipedia and you'll see a number of them apply (Herd Effect,
Focusing Effect, ...).

http://en.wikipedia.org/wiki/List_of_cognitive_biases

- Hiding comment scores prevents turning a discussion into a
game of winners and losers. Forcing a discussion into being a
measured win/lose debate encourages competition, animosity and
opposition.

I am perfectly content listening to opinions different than my own, and
I encourage people to voice them. I actually want to know what they
think and why they think as they do. I may or may not ever change my own
mind, but learning and knowing differing views gives one more
perspective. If the discussion was escalated into an adversarial
competition, I might not ever get the chance to hear your side.

- There is really no universal definition of up or down votes. To
the person making the vote, it could be a measure of agreement,
usefulness, appreciation, insight, merit, or many other things. If you
don't know what was intended by the voter, letting their views taint
your own is entirely foolish.

I care far more about being fair to you, than I care about what other
people MIGHT think of you or your opinions.

I personally prefer the transformational model, but for many students that is neither desired nor likely to succeed.

Many students, in all sincerity, do not want to be transformed. They want the job ticket.

I don't think that everyone should be forced to accept a traditional liberal arts notion of university. I think instead that fewer people should go to university, and many universities really ought to be trade schools instead.

It is the signalling value of university education that has caused its dilution; much as the signalling of peacock feathers has rendered the male peacock quite useless.

They recommend Racket as well and that's a good a recommendation as you're likely to get for a current Scheme suitable for the material. Although as said MIT Scheme is just fine.

Preemptive multitasking by itself isn't very interesting. It's useful if you're running a real-time control task (in which case, on MS-DOS, you would hook an interrupt, and fuck the lack of OS) or if you have memory protection, which the Amiga didn't. That's why the mainstream OSes didn't have it for another decade: because it didn't matter. (And concurrency control is much simpler without it.)

The Amiga had lots of other awesome stuff in the late 1980s, stuff that (as others pointed out) still isn't mainstream. But preemptive multitasking without an MMU is mostly a waste of time.
I would change the design to encourage more reporting, and make it harder for bots to crawl.

Thank you for noting that it's a Windows computer virus, not one of those menacing malware viruses the media tells everyone, even Mac and Linux users, are going to destroy their lives.

Note that even though Macs and Linux boxes can certainly get viruses (http://virus.bartolich.at/virus-writing-HOWTO/_html/index.ht...), statistically speaking, they absolutely will not. There's something else going on with Windows (cultural, baroque system interface, something) that allows a flood of malware.

I'm familiar with the Grand Tour, but your chronology seems backwards; the Grand Tour was a 17th-century creation, while the humanist university coalesced by the 15th/16th.

It wasn't limited to theology, though that was some of the original impetus; even the 13th-century universities commonly taught law, philosophy, and medicine. Through the 14th/15th/16th centuries most of the rest of the subjects were added: mathematics, astronomy, literature, etc. Galileo, for example, held a university chair in mathematics a century before the wealthy started sending their kids on the Grand Tour.

Indeed from everything I've read, university students were seen as stereotypically poor up until around the 18th century, living either at the university in vaguely monastery-type conditions with common dining and small quarters, or attempting to rent cheap rooms from townspeople, sometimes leading to tensions as locals felt the influx of poor students was ghettoizing the area (the area around the University of Paris was slightly notorious for centuries).

I don't know if people think about it economically. If they did then you might say:

There is a nuclear reactor near here.

If there is a 9+ magnitude quake with a matching tsunami then the water surge will probably kill you. If you survive that you may have to evacuate for a couple of months while we get the nuclear plant back into a stable configuration. This has never happened in recorded history but it is possible.

Are you sure you want to buy/rent this house and live here?

Hammock your statement "Nuclear accidents on the other hand are something that we can prevent, either by more robust disaster planning, or by not having nuke plants in sensitive areas to begin with." implies that we haven't prevented them, when in fact we have. Japan has had very large earthquakes before and their nuclear facilities have come through unscathed. This particular event will, in all likelyhood, kill no one out right and probably not change the life expectancy in any measurable way for more than a handful of people. So while the statistically amazingingly unusual earthquake + tsunami got through the back up cooling system defenses, the 'worst possible' scenario you might imagine, and no one has been killed? I'm pretty sure most people would take that bet and decide to live there.

They would be even more likely if they realized that just flying on a commercial airliner once a year has a better chance of killing them.

I understand the fear that radiation induces in people, they can't see it, they feel like they can be 'dead' already and not know it, and there really isn't a good way to hide from it (unless perhaps you have a lead lined shelter). But it is more of a phobia than a rational fear. There are many places you can live where there is no risk of a nuclear accident and if a person's phobia is strong, they may choose to live there, just as people who fear of heights may choose to live in single story structures.

There is however an even bigger threat, for which we completely understand the threat and are not doing a damn thing about. Yup, the bad news is that pretty much anywhere on the planet you can be killed by an Asteroid impact [1] which, surprisingly, is about as likely than a 9+ quake and a tsunami [2].

And perhaps more telling, given the inverse square law, you can actually build a shelter that is impervious to any event at any reactor for any given distance, but you can't do that for a space rock.

[2] Paleoseismic evidence shows that great earthquakes or earthquake couplets occur about every 230 years (http://www.gps.caltech.edu/~sieh/publications/a10.html).

From your wikipedia link:

"There is a spectrum of commodification, rather than a binary distinction of "commodity versus differentiable product"."
My understanding is that while students were poor in a sense -- little to no income - they tended to come from wealthy families. Otherwise they simply had to get work or starve to death, which precluded almost everyone from study.

The tradition of the poor rich kid has endured to this day.

Thanks for correcting me on the Grand Tour.
