lolcraft··on Harvard 1869 entrance exam
Another "proof":

x^n = exp((log x)n). By definition, exp(n+m)=exp(n)exp(m). By definition, a(b+c) = ab + ac (for the log x thing). QED.

By the way, (the infamous calculus book) Baby Rudin has the poor reader show this property holds in exponentiation for reals, starting with integers and via rationals, as an exercise on its first chapter. Insane difficulty for me, even though the author practically holds your hand along the way! Cool read, though.

lolcraft··on Tell HN: Unhappy and I don't know what to do.
CBT is definitely not about getting you to settle. Seriously. I've been there. Go.
lolcraft··on Esther Dyson vs Bill Campbell: 2002 − 2012
There is no such pernicious myth today as the "right-wing pro-business" government.

An example: progress requires, above anything, a rentier class not hell bent on furthering their greed at the expense of everyone else, via shadow banking, obscure contracts and general, short-sighted stupidity. Regulated, if you will.

I don't see many "pro-business" governments doing anything to solve that. I see many of them giving their corporate friends cool, undeserved subsidies under the pretense of "industry being of national interest".

lolcraft··on What being hopelessly single taught me about pitching tech celebs
Things are complicated. Beware of the potential phonyness lurking there. "Instead of making a business offer, pretend to be friends long enough so that the other party will (maybe) want to make business with you."

Cool and all, but sometimes a pitch is just a pitch, and a fuck is just a fuck.

Also: personally I would never start a business with a friend I really cared about. Never. It's just like having a "friend with benefits": it can go perfectly or it can be hell on earth.

lolcraft··on Diamond planets, climate change and the scientific method
That argument reduces to:

* The medieval warm period was warmed than today, which is false; thus * Solar activity might be the cause of large climate changes, which is doubtful, more so because the premise is wrong.

Not enough to explain ocean acidity, why climate change is global, why there's a hole in the Antarctic's atmosphere...

lolcraft··on Wadler's critique of SICP (1987)
I think that's more a libraries thing that a language thing. For example, you can do very cool, HTMLy things using Racket's web-server/servlet and Scheme continuations, which would be incredibly hard to do in C.

But I agree with your suggestion that C should be teached first. If anything, because C's "computational model" is very simple: you know what executes when; it encourages a more common, procedural way of thinking, and it's easy to do side effects in single-threaded C.

lolcraft··on Getting Bin Laden: What happened that night in Abbottabad
It's simple, really.
lolcraft··on I am an HFT Programmer
Time can be exchanged for money. Money can't be exchanged for time.
lolcraft··on Why I will never pursue cheating again
This type of condescending, defensive reply enlightens no one.

I mean, equating anxiety about being accused of something to actual guilt... that's thoughtcrime. Implying that the GP is so stupid that he/she couldn't distinguish racism from bad mood... that's a straight insult.

lolcraft··on Ask HN: What documentaries are worth watching?
Just saw it. Glorious. A two hour guide on how to hack the art market, and a fine piece of film. Do recommend.
lolcraft··on CIA.gov Possibly Down, LulzSec Claims Responsibility
It's still a form of regulation, highly or otherwise.
lolcraft··on Myths About Introverts
Smalltalk is social exploration. Maybe a better word might be social probing. In this stage, you can't go directly to the point, because smalltalk is useful only in evaluating the point of a future conversation with the same partner.

Of course, people that think "no point yet" = "not valuable ever" might want to pursue philosophical nihilism until terminal depression. But I digress.

lolcraft··on Why we are unlikely to ever leave the solar system.
The survival of your species after your death is not a vested interest (a "special interest in protecting or promoting that which is to one's own personal advantage"). It affects you nil, by definition: you will be dead by then.

What affects you is having children before you retire, because then you'll be fed and survive a lot more than otherwise. Evolution is a conclusion of that, not the other way around.

lolcraft··on The brain's 5-million core, 9 Hz computer
Leibniz was an idealist. He lived in peculiar ideological waters: he was Christian. He had to believe that there's the mind, there's reality, and both never touch. If he ever went out the party line, the inquisition would take care of him.

According to Leibniz, neurons can't exist. Exercise does not improve your mood. Brain surgery is useless. Caffeine does not work. Hormones do nothing. Coma is unexplainable by definition. And so on.

Reality killed Leibniz.

lolcraft··on C++ at Google: Here Be Dragons
C++'s typing is fairly weak. Most of the errors shown in the article were weaknesses of the type system. Now Haskell, or even Java...
lolcraft··on A better way to teach math
Are gifted children that much helped by the current system? For all I know, they are just ignored.

Furthermore, where do you read that the objective is "low variance"? I read "higher average".

lolcraft··on Ask HN: Are There Any Compelling Reasons To Continue Using Firefox?
Why do you say that? I am using AdBlock Plus in Chromium. It works fine, as far as I notice.
lolcraft··on Review of Ayn Rand
It is odd to me that people care one iota about Ayn Rand the person.

I'm not convinced that the ethics of any philosopher, a matter of praxis by definition, should be considered strictly apart from the values which that philosopher really acted by (as this article portrays). Not following your own ethics seems as dishonest as openly proclaiming "do what I say, not what I do", as dishonest as an evolutionary biologist advocating creationism in their free time. Because of this, IMO the article does not incur in ad hominem for presenting Rand's life.

lolcraft··on Facebook Admits Censoring Content in Pakistan
A more interesting, if obvious, related question: shouldn't we, through our political representatives, demand that corporations carry a little bit more of social responsibility?

That would be the rational thing for us to demand, since a more liberal Pakistan would make both us and Pakistanis happier. Nowadays it is a matter of corporations' interest rather than law.

lolcraft··on "Playing God" is a meaningless, dangerous cliche
can quite sensibly be used by atheists since it means "assuming powers which should only belong to (hypothetical) gods"

Sorry, but I refuse to call atheist to anyone who believes that an arbitrary, human-made list of values can be "godlike" in any meaningful sense. If anything, should that person use that list of values to base their political or scientific arguments, I would call them theocrats.

lolcraft··on [dead]
Wasn't losing the savings of half a country the consequence of not doing that? See Great Depression, Argentina's corralito, etc.
lolcraft··on Ask HN: What streetsmarts have you learnt?
The term "suffering" in the GP's post should, IMO, be understood as "pain", which is nowadays more tuned-up to the Buddhist/Nietzschian concept of suffering. Maybe we westerners have identified too much the term "suffering" to "sadness", the latter being the worst, most passive way with which one can react to pain.
lolcraft··on For loops help - comp.lang.c
Not really. Almost any numbers would do, since z is an int and integer division "a/b" in C means not exactly a/b, but its floor. For instance, "2/2/2".
lolcraft··on Lambda-style anonymous functions for C++ in less than 500 lines of code
To pull this off, the implementation exploits templates, operator overloading and function pointers (but, remarkably, not a single macro) to construct a type-safe domain-specific embedded language.

Yes, "exploiting" is exactly the word I was looking for. Cool hack, though.

lolcraft··on Hallucinogens Have Doctors Tuning In Again
Alcohol can kill you. Psilocybin can't, but it is at least possible that it can lead to mental illness.

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

"Alcohol is also a common risk of causing psychotic disorders or episodes. Research has shown that alcohol abuse causes an 8-fold increase in psychotic disorders in men and a 3 fold increased risk of psychotic disorders in women. Alcoholic psychosis is sometimes misdiagnosed as a mental illness such as schizophrenia."

The people I'm talking about are the party types who are using these drugs all the time, to the point that drugs are the only things in their lives.

That doesn't seem a very strong argument. I would argue that everything is subject to psychological addiction. Gambling, World of Warcraft, the Internet, sex... it's physical addiction what should be controlled. I could see the point on banning, say, crack. Or alcohol. Or tobacco. But hallucinogens?

lolcraft··on Betraying Salinger
I read somewhere that most content ceases to be profitable at about 10, 15 years past release. I'm sorry, I'm not able to find it now, but if that's true, it would mean that publishers would indeed have an incentive. The benefits from printing new editions of old books wouldn't be much in comparison, being more competition. I do, indeed, think it's true.

I somewhat feel sorry for the authors, but I think they'll manage. Being a writer is already a respected and highly-sought status, even though the pay is poor. Either way, I wouldn't claim copyright durations of ten years. But we can't stay like this eternally.

lolcraft··on Betraying Salinger
In the XVII century, copyright in Spain was a period of ten years long, since the first edition, not renewable. I'm talking of a country notorious for its steep geography and bad communications, at a period of both dangerous colonisation, wars and abject poverty. That century is now known as the Spanish Golden Age of Literature.

History has proven that, past a point, money does not seem to translate into creativeness. Cultures almost always have their most creative periods at times of social and intellectual changes (say, XIX-XX century Germany) and when intellectual work is regarded as prestigious and respected by the public (physics on America post-Einstein/WW2).

lolcraft··on Money can't make me happy, says millionaire giving his riches away
Live? That seems difficult enough to me.
lolcraft··on Ask HN: From what countries do people use HN beside USA?
Spain
lolcraft··on Why the best and brightest students in India choose to be engineers
Europe (Euler, Gödel, Erdos, Hilbert, Einstein) and America (von Neumann, Shannon, Feynman) have comparably long traditions and cultural icons. I don't think lack of them is the cause.
