pfedor··on Myths of Password Security
The problem is, if you actually choose your 4 words randomly out of the full dictionary, you won't get something like "golf kangaroo crispy halitosis" or "correct horse battery staple". It will sound closer to "capaciously endodermal remast amarantite". The set of words as familiar as "golf", "kangaroo", etc. is much smaller than 100k.
pfedor··on 3 In 10 Americans Will Not Knowingly Buy Chinese-Owned Brands
Would you mind if I ask you to elaborate? I can think of two ways to read this

1. If the USA bombs China, and China fights back, that means a global war and global wars accelerate the progress of science and technology, therefore in the long run people in Wisconsin will be better off just like quite possibly they are better off now than they'd be in the alternative universe where World War II never happened (where they might not have satellite TV, GPS navigation, nuclear energy, computers etc.)

2. If the USA continues to trade with China, in a number of years China may become equally as powerful as USA or more and then China may choose to go to war with America and win.

Did you mean any of the two? I'm assuming the long run part is critical since in the short term it's fairly obvious that people in Wisconsin and everywhere would be worse off if the US bombed China.

pfedor··on Why Young Americans Should Work Overseas
I couldn't find reliable figures for China, India, Brazil or other countries, but I'm very certain I'd rather be in the top 10% of those countries than the bottom 10% of America.

You'd be right about Brazil.

I like people in Wisconsin, can't really relate to people in Chengdu

The people in Wisconsin will be better off if they produce something at which their comparative advantage is the highest. You'd harm them, as well yourself and the Chinese people, by shifting the allocation of resources slightly away from optimal for all these parties.

pfedor··on Richer countries are happier than poorer ones. Richer families are happier too
Yeah, they clearly don't realize that, that's why the article says, "Statistical note: This graph is logarithmic. That means doubling your income from $1,000 to $2,000 raises satisfaction by the same amount as doubling your income from $10,000 to $20,000."
pfedor··on Richer countries are happier than poorer ones. Richer families are happier too
It is worth repeating that the original paper, by Kahneman and Deaton--the one everyone likes to cite to support the opinion that happiness doesn't increase with salary above $75k--said nothing of the sort, unless you accept a very peculiar understanding of the word "happiness". The paper introduces two concepts, "Emotional Well Being = the quality of a person’s everyday experience such as joy, fascination, anxiety, sadness, anger, and affection", and "Life Evaluation = a person’s thoughts about his or her life (on a longer time scale)." The first one, K&D found, is only affected by money up to $75k a year. The second is improved with more money at all levels. http://wws.princeton.edu/news/Income_Happiness/Happiness_Mon...

So unless you're going to insist that the word "happiness" only pertains to temporary feelings, as opposed to how you feel about your life overall in the long-term, the claim about $75k and happiness never had any basis in data.

pfedor··on How to eat healthily on £1 a day
I'm guessing he's referring to the fraction of underweight children, 5.1% below the poverty line and 5.7% above 4x the poverty line.

Not sure whether 4x should qualify as "rich", but more importantly, being underweight is pretty low bar. For example, I am underweight.

The actual number as reported by USDA is 1%. The keyword to look for is "very low food security", formerly known as "food insecurity with hunger", which is the lowest range of food security measured by USDA. (The second lowest range, "low food security", formerly "food security without hunger", means poor diet but no reduction in food intake. Note that even among the "very low food security" households less than half reported "lost weight" and less than a third reported "did not eat the whole day".)

One interesting observation: "Typically, households classified as having very low food security experienced the condition in 7 months of the year, for a few days in each of those months." I'll go out on a limb and hypothesize that these few days are the last few days of each month. So one thing to try to reduce that number would be making welfare payments daily, instead of monthly. (I read that welfare these is delivered electronically, you carry a special card which looks like a credit card and a certain amount appears on it the first day of each month. So it shouldn't add any overhead to switch to daily installments.)

Sources:

http://www.ers.usda.gov/publications/err-economic-research-r... for the 1% number.

Haxe did nothing you couldn't do with AS3 and Alchemy.

So, have they fixed this bug in Alchemy: http://forums.adobe.com/thread/487570

It's kind of hard to use C++ when you're not allowed to make a copy of std::string. Last I looked into this in May 2012 this was still not fixed (reported in 2009.) There is a page on stackoverflow where someone explains how to work around this problem by rebuilding a patched version of libstdc++. But after applying that fix you hit other similar problems.

Also, the sztrace() function exists and is documented, but they forgot to add it to the .h file, so if you want to log anything, you have to write:

  extern "C" {
  void sztrace(char*);
  }
pfedor··on Why it is important not to have children
Increasingly smaller fraction of humanity is has a problem getting water or food, from almost everyone not that long ago, through 40% of the world population in the 1980s to less than 20% nowadays. This change is due to economic growth, which in turn is influenced primarily by the technological progress, also by politics, governance, and culture, as you say, but also by the population growth--when there are more people the economy grows faster.

Also note that regardless of what you think in general about the impact the growing number of humans has on the economic growth, it's hardly debatable that if Richard Stallman specifically had decided to have children, his children would have very likely contributed much more than an average human, just like RMS himself has.

So in reality his decision was exactly counterproductive providing parts of humanity with water or food.

To all the parents out there (I am not one): Thank you. You don't know me, but your decision to have a child is as good as if you donated maybe $1e-4 to my 401(k). And everyone else's. If you live in the US, more. If you are a very smart and hard working person, even more. By caring for your own child, you're also feeding some hungry child in Africa 25 years from now. Richard Stallman should be grateful to you.

pfedor··on The world’s top industries would be unprofitable with externalities priced in
Saying the market wouldn't have still gone through the industrial revolution is tantamount to saying that industrial society is not economically efficient!

Isn't that rather like saying that there wouldn't have been a strictly monotonic route from the pre-industrial society maximum to the industrial society maximum? There might have been, or might have not been, but a priori it's not absurd to postulate that with coal tax from day 1 the road to a more efficient final state wouldn't have been blocked.

pfedor··on Taping of Farm Cruelty Is Becoming the Crime
it appears to me that almost the entire US legal and political system is driven by, and for the benefit of, corporate and big business interests

"Corporate and big business interests", i.e., publicly traded companies, are responsible for the majority of wealth creation (source: well it's obvious, but see for example William Bernstein, "The Birth of Plenty".) So what you said can be rephrased as, "The US system works to enable wealth creation", or in other words, "The US system is optimized for providing the best standard of living for its citizens." Which is exactly the case.

pfedor··on Ex-Prime Minister Baroness Thatcher dies, aged 87
helped bankrupt the USSR

Which alone should be reason enough to declare anyone a Saint and then give them the Nobel Peace Prize for twenty years in a row.

pfedor··on Ex-Prime Minister Baroness Thatcher dies, aged 87
Or to put it another way, how could it have been worse?

Easy. The coal mining industry could have continued existing for another thirty years, bringing huge losses each year, subsidized by the taxpayer. Like, say, in Poland, which is where you get your cheap labor from, and not the other way around, and the two facts are not entirely unrelated.

pfedor··on My Code made it to a Hollywood Movie
Yeah artists seem to do it all the time. They also often get indignant at the merest suggestion that they might want to agree for someone to use their work for free.

The difference is, of course, that writing code is joy so no wonder people will gladly do it and give the results away, whereas creating art is unpleasant, tiresome work, so it's an insult to suggest anyone would do it for reasons other than money.

pfedor··on The Disposable Academic: Why doing a PhD is often a waste of time (2010)
The decision to enter a PhD program only makes sense for one of the two reasons: either you think you're going to win a Nobel Prize one day, or, you don't mind spending five years in a way which doesn't advance any goal (literal quote from a conversation I had, "so you had an offer from Google but you decided to do a PhD instead--why??", "Oh, I just want to do nothing for a while longer".)

The two kinds of PhD students may look the same but they're very different. If you belong to the first category, even if you realize you won't get that Nobel Prize, I doubt you're going to regret trying. If you're of the second kind, why yes, you have wasted five years of your life, which is exactly what you signed up for so why do you complain?

pfedor··on Want to Help People? Just Give Them Money
The developed world has an exponentially higher cost of living than sub-Saharan Africa or rural India

Which is irrelevant since the $2 a day figure is adjusted for purchasing power parity.

pfedor··on What it’s like to die
I was curious so I looked up the numbers on wikipedia: http://en.wikipedia.org/wiki/Cardiopulmonary_resuscitation#E...

The survival rates are:

CPR by a bystander: 4%

Cardiocerebral Resuscitation (i.e., chest compressions only without artificial respiration): 6%

No bystander CPR: 2%

So attempting CPR results on average in doubling the survival rate as opposed to just waiting for an ambulance, and chest compressions only are 50% better than chest compressions plus mouth-to-mouth.

pfedor··on Confessions of A Job Destroyer
In the USA as of 2013, everyone already has their basic needs taken care of--or at least what Bertrand Russel would consider the basic needs, of course we have redefined them since to mean things which in his time would have been considered luxuries.
pfedor··on Silicon Valley Poverty Is Getting Much Worse Amidst Insane New Tech Wealth Boom
Their neighbors are slightly worse off, and 20 people have a place to live.

That is what happens when only one landowner chooses "defect". If all of them do it, then 20 people times the number of lots might find a place to live, except it's no longer the kind of place where they want to live.

Or put another way, there is already a lot of places where you can live cheaply, it's just that a lot of people would rather live in Palo Alto than in those places. But if you turn Palo Alto into a housing project, then the reason why they want to live there might stop existing, because all the rich people, who are the reason the rest of us want to be in the Silicon Valley, likely prefer not to live in close vicinity to "bigger buildings filled with tinier apartments."

Of course I don't have a glass ball and cannot know for a fact that's what would happen, but it doesn't seem far fetched and at least personally I find it no less believable than many other tragedy of the commons situations which are posited to justify this regulation or that.

pfedor··on Silicon Valley Poverty Is Getting Much Worse Amidst Insane New Tech Wealth Boom
Zoning laws seem like one example of a regulation that genuinely prevents the tragedy of the commons. If one person built a twenty story house on their property, that person would get rich and all their neighbors would be slightly worse off. If everyone did that, the business owners and VSs would move somewhere with less traffic and fewer neighbors, the software engineers would follow and Palo Alto would become just another slum.

I've never lived in a small town, but if literary accounts are to be believed, it was hell for precisely this reason.
pfedor··on Hacker News Parody Thread
The metric which would be a tad closer to ideal would be some average of u/t where u := the number of users who upvoted a given comment, t := total number of users who saw that comment. Where "saw" can mean either "the comment was already there when the user loaded the comments page", or, if you want to get fancy, "the comment was within the browser's viewport long enough to be read" (which some clever JavaScript can tell you.)

pfedor··on Are You Living in a Fourth Amendment Exclusion Zone?
Let me repeat what has been said in the other Hacker News threads about the same story:

This is neither the law nor the actual practice in the US. It is just something crazy that DHS once said. If they ever actually searched someone 100 miles away from the border, that person could sue and there is no reason to believe that the verdict would be different from Almeida-Sanchez v. United States.

pfedor··on Heroku Fucking Console
Oh, I also can say and hear "fuck" all day long without blinking, because, like you, I am not American and English is not my native language. However, there are words in Polish which could make me cringe, especially when heard unexpectedly. Profanity is like poetry: it only works in your mother tongue.
pfedor··on Uncopyright
Those people would be benefitting from the original pirate's crime. Generally feigning ignorance is not enough to absolve you from the responsibility in such cases. If you buy a stolen car (even not knowing that it was stolen) the police will take it away from you and will not reimburse you, and you may be even looking at jail time.
pfedor··on Uncopyright
The fact that you are not the original author has nothing to do with the author exerting any control, it is a question of fact. Beethoven no longer exerts any control over the Moonlight Sonata and yet it is a fact that he wrote it and not you. Why should it be any different for a more recent work released to the public domain by the author?
pfedor··on Uncopyright
There is significant debate as to whether public domain even exists except through copyright expiry.

Such serious claim requires some serious citation. It is certainly not true as stated, since all original works produced by the government are in the public domain regardless of when they were created (e.g., NASA images and many US coins designs.) The first Google result for [public domain existence debate] is your comment. I haven't come across any evidence that any such debate exists, and plenty of sources to support the fact of the existence of public domain (some given by others in this thread.)
