rortian··on Ask HN: Managing my own server.
To start out free, google app engine is a good way to go. It is a little quirky and different from most solutions, but it's great to start paying nothing.
rortian··on GNU HURD: Altered visions and lost promise
I'm semi-intrigued, but I'd like to see a sign of life beyond a page from '98. Not trying to be cruel, just saying that'd I'd like to see what's going on now.
rortian··on GNU HURD: Altered visions and lost promise
Indeed. It'll be interesting to see if people use Maxine VM a lot to run Java stuff on a xen/micro-kernel environment.
rortian··on GNU HURD: Altered visions and lost promise
But not at all as a general computing environment. It makes sense once you have your application finished that you could move it to a kernel that has just what you need. However, it makes no sense when you start development to try to guess what calls you might end up using.

>I am a would be undergrad

>Sociology, Psychology, and women studies do matter, but the way they are currently taught is nothing but intellectual fraud.

At some places but not in general. If you had started reading when you were two you wouldn't be able to categorically make this statement. Chill out on proclamations about things that you couldn't possibly know.

I personally don't have any. Imo, the article doesn't add very much to anything and its title is misleading. If I would suggest a change it would be not submitting in the first place. This is hardly an article that I would flag though.

rortian··on A Neuroscientist Uncovers A Dark Secret
Don't liberals hold...

I really hope you learn that saying things like this points out to people that you are willing to stereotype a huge number of people of whom you are completely ignorant. Also, there wasn't really an issue here. It was a human interest/science story about a scientist learning he is similar to the people that he has studied. Interesting story without an issue being focused on.

On the last question give me a little time to look up a paper. I'll post it. Essential it shows how the strategy of most long-short hedge funds work. I'd have to look again, but one of the major high frequency strategies uses a version of this.

I'd love to read it, but the easiest way to answer your second question is to point you to 'A non random walk down wall street.'

One huge assumption that Black-Scholes makes is that returns are normal distributed. This is not done for empirical reasons rather mathematical ones, namely it is so convenient.

Some meta data and such if you don't feel like going with a pdf:

Cool, definitely get back to me. Kinda random but I am very interested in complex networks as well as some finance stuff.
rortian··on I might be a complete failure (after 8 years of work)
An interesting post. I'd be interested hear what kind of background you've got.

I think your remark on finance professors is quite wrong. It takes quite a lot of dedication to do a Phd. I'm not great respecter of academic prestige, but its a bit insulting to imply that people fail their way into a professorship.

I'd be more than happy to share some pointers on financial papers I've read and such. Just talk about your background and what you know. If you think 'a random walk down Wall Street' is correct, it isn't. Have you seen the derivation of Black-Scholes? Do you know what most high frequency trading is based on?

I'd also be interested to see what type of stuff you like to read.

rortian··on The Sobering Reality of Entrepreneurship in the U.S.
I'd love to see you produce so data for any of these claims. People in Japan get access to MRIs for much cheaper than Americans. How is that a bad thing?

The median real income has been hardly been growing at a fast rate. You'd need it to get growing at an incredible 10% a year for your explanation to be at all credible.

rortian··on The Sobering Reality of Entrepreneurship in the U.S.
>because those systems force the price down below what people would be willing to pay on their own

This is very far from the truth. Worry not, rich people can spend to their hearts content in single payer countries. They still spend less and have better outcomes.

In the abstract maybe we do want to spend a lot of money for health care. However, medical costs have been growing at double digit rates. Hopefully that pattern does not continue for too much longer.

rortian··on Mike Lee on why he can charge $1,000/hr for iPhone development
Bringing murder up to justify a moral scheme that few subscribe to is a bit silly. Everyone finds murder wrong, in most circumstances, hardly everyone finds taxing the rich immoral.

These things are complicated. Wealth can be generated in a variety to ways. The Phoenicians were quite wealthy for their time for establishing a trade network in the Mediterranean.

Apple produces virtually nothing (okay they make software but lets pretend for a minute that we are talking about the hardware. People do rave about the aesthetics of the devices). However, they have plenty of 'wealth' to capture than the manufacturers do for their charging price. They having marketing savvy and they are able to get large numbers of people excited about what they think of.

Facilitating transactions and applying knowledge are not exactly producing but doing these tasks can provide a decent living. If you want to extend 'producing' to mean anything that makes people money, your statement could be a truism but it seems you are using produce in a more traditional sense.

rortian··on The Sobering Reality of Entrepreneurship in the U.S.
Just show me where the US excels, especially on per dollar terms, on health care on any metric relative to any other modern industrial economy.

We spend more on health care in large part because we have way too much surgery going on. There's other stuff going on too, but there's a lot of waste to go with us 'valu[ing] it so much'.

>not capitalists advocating efficient trade, they're Keynesians or something.

Keynesians are capitalists and I've never heard of them being opposed to efficient trade.

One thing that inspires people to spend money is feeling that they won't be laid off. People do not have that feeling right now. Should we just wait for that to happen? Producing while people aren't buying leads to inventory gluts which leads to deflation.

http://www.nybooks.com/articles/archives/2007/feb/15/who-was...

>Milton Friedman played three roles in the intellectual life of the twentieth century. There was Friedman the economist’s economist, who wrote technical, more or less apolitical analyses of consumer behavior and inflation. There was Friedman the policy entrepreneur, who spent decades campaigning on behalf of the policy known as monetarism—finally seeing the Federal Reserve and the Bank of England adopt his doctrine at the end of the 1970s, only to abandon it as unworkable a few years later. Finally, there was Friedman the ideologue, the great popularizer of free-market doctrine.

I'd have to suggest that this statement came from the 3rd Friedman. There is sort of an irony here. Friedman saw monetary policy as a zero sum game. I think that was a fallacy.

>This PG essay is a good refutation of the notion that (progressive or, at least, non-regressive) taxes are a "win" for the poor in a zero sum game:

This is a straw man. I cannot think of anyone (and I'd love to see you find a progressive or anyone) that would say that economics is a zero sum game.

A lot of this community did form around pg's essays. However, it's a little sickening to think that anyone would take them as gospel. Since the early days of reddit and hn these things have been vigorously debated. pg is at his best when talking about start ups and I think the way he conveys how founders should think is good stuff. However, please do not expect, or treat his writing, like he will win a nobel prize in economics.

rortian··on Mike Lee on why he can charge $1,000/hr for iPhone development
I'm down with what you suggest. The problem with the economy now though is that we have excess capacity. I'm down with going around and blow up factories to solve this (only kidding fbi) but I think it would be easier if we could stimulate demand.

>This is also why the Internet creates economic value, because it's able to more efficiently pair producers and consumers.

I would say that is one reason why but I whole heartily agree.

rortian··on Mike Lee on why he can charge $1,000/hr for iPhone development
>Immoral too.

Classic. Moral claims don't get you too far. I could start going on about gentiles eating shellfish, but I'm one of those gentiles.

>They do by producing

Sometimes. These things are complicated. But if you've already got it figured out, no need to discuss it I guess.

rortian··on Mike Lee on why he can charge $1,000/hr for iPhone development
Wow.

Libertarians are here, sure. However, I'd love to see how many people would really march in lockstep with doctrinaire libertarianism.

I'm not ignorant of libertarian views. Nor, am I unused to tantrums such as your own. I'll leave the vocabulary boot camps to you and Richard Stallman. I have that freedom.

rortian··on Mike Lee on why he can charge $1,000/hr for iPhone development
Fascinating definitions but this has more than a whiff of crack pottery. Few things encourage economic activity (and productivity) like a rich person coming with an open wallet.

How are people to work more when there's not money to pay them?

rortian··on Mike Lee on why he can charge $1,000/hr for iPhone development
Marginal tax rates being high is a great idea. I'd be with you if people with high salaries spent all, or virtually all, of their salary. But they don't.

In this economy we need more money being spent. When things are doing well again, you could try to make a case for the rich being richer, but it's a strange cause to take up.

You don't have to search hard to find that everything Apple makes, he will assert that it is the best in the world.

I'd have to look into it further, but I think getting a summary judgment is pretty damning. There are cases that get a summary judgment that do go onto getting overturned by the Supreme Court, but statistically those are, of course, quite rare.
rortian··on Obama Administration Announces New Anti-Piracy Initiative
I'm not so sure this is right. They want a high quality file and hopefully one that is trojan-free etc. Thus, there are several 'name brand' ripping groups.

The bill is in conference committee because they passed two different bills. They have to try to craft a bill that synthesizes the two and (crucially given the filibuster) that can pass both houses.
