  1. Soo... on Battery Materials Made Using Crab Shells · · Score: 4, Informative

    So if I understand this correctly, by increasing the surface area of the electrodes, you increase storage density. We already knew that. The problem is those electrodes corrode over time... ions swap between the two plates, which is why we don't go through the effort of manufacturing them with lots of little pits and twists in them, because they'll just corrode that much faster. No pure metal can resist this, and alloys that can generally make poor foundations to build batteries on. Plus there's manufacturing cost. For something like a car battery... that's important. For something like a cell phone, I can see some merit in making batteries with a higher energy density at the tradeoff of shorter life. Of course, they're already pretty short right now...and expensive. :(

    People who are interested in the material will do well regardless. Saying that those who are self-taught and not "academically-shaped" get more respect is, at best, wishful thinking or egotism.

    You can take that up with Eric S. Raymond, the social anthropologist who studied hacker culture, and wrote this in Appendix D of the Hacker Dictionary, titled Portrait of J. Random Hacker. By all means, go ahead and tell him it was wishful thinking and egotism. Let me know how that goes.

    I think public education itself here is a major problem. Most children are being force fed knowledge and asked to regurgitate it on command. Forced learning like this doesn't stick very well; That's well-established in psychology. Self-directed learning requires more teacher-pupil involvement and support from the parents, but it results in a much more rounded education.

    I'm pretty much self-taught from 5th grade forward on all the primary school subjects; I just needed help with reading and after that I was on my own. I did very poorly in public education, but by the time I was 18, I took my GED and went into college. I can't tell you who the first ten presidents of the United States are, or regurgitate the talking points of War and Peace, but I can tell you why WWII happened, why Hitler had broad public support, show you pictures of him kissing babies, and not just say what happened, but why it happened. I can do basic trigeometry in my head and estimate distances pretty accurately just by looking at objects in real life. I don't just understand science, I practice it in everyday life. I don't just know that "sex is bad" like health class taught you: I volunteer at Planned Parenthood.

    Education that a person is involved in doesn't just lead to a better understanding of the world, but also an innate sense of responsibility for that world. And what does any of this have to do with programming?

    If I'd stuck to the curriculum shoved down my throat in school, I wouldn't have gotten into computers. I discovered it on my own. Then I taught myself programming. And now, professionally, I very often find myself teaching others how to do the same. And programming, more than many other topics, requires self-directed learning. It doesn't work very well under the existing "force fed" public education system... What you get is bored students who hate computers, and can't design anything much more complicated than counting loops that say "this class sucks 1. this class sucks 2. this class sucks 3. if this class sucks, then this class really sucks."

    In the hacker community, the self-taught hacker is often better respected than his academically-shaped peer, and the reason has nothing to do with a disrespect of education, but rather an implicit understanding that you just don't learn as well unless you're interested in the material and follow your own path through it.

    Lots of people turn to raping after making speeches criticizing the primacy of the U.S. dollar, or revealing U.S. top secret documents. Hell, it wouldn't surprise me if Edward Snowden weren't considering raping some poor women right now, or molesting kids, or selling secrets to the Chinese, or kicking puppies.

    In politics that if you can't attack the message, you attack the messenger. The United States has several organizations dedicated to discrediting people who come forward with allegations of impropriety against the government. It is a standard tactic used by many governments; Distributing disinformation is a time-honored military and political strategy.

    And it is very effective. Just look at this thread: Some people have been completely taken in by it and the discussion now revolves not around the correctness of whistle blowing, or whether society benefits from an organization like wikileaks, or if what the government was exposed in having done was right or wrong... the entire discussion now centers largely on Julian.

    There is an example of a purely unregulated market; EVE Online.

    I play EVE. It's not a "very stable market". Goonsquad decided to attack miners in highsec. Mining is one of the main ways raw materials are generated for product generation, and when they did that, key resources to fuel starbases (oxygen isotopes, etc.) shot up massively in price. It would be the realworld equivalent of bombing oil pipelines and refineries.

    As you get farther away from the main trade hubs and out into nullsec, prices can easily triple for commodities. And many alliances have policies to prevent anyone else from getting in on their lucrative cartels of freighter transports bringing needed supplies out.

    But within EVE Online everyone is a professional trader, not some dude/mom/dad who just gambles some money on the stock market from behind his PC like it happens in the real world.

    Like hell they are. Most people avoid serious trading because of the lack of easy access to information on sales volumes, pricing, etc, market volatility, and (unlike the real world) getting your products to one of the main trade hubs is risky. If blowing your ship to hell is cheaper than the cost of losing their ships to the police (concord), they'll blow it up. There's no jail in Eve -- in 15 minutes you're just like every other pilot again... and they'll loot your wreck and be on their merry.

    I suggest that everyone plays EVE Online so that people learn about markets, about logistics, about profit per hour (just profit is for noobs).

    And I'd suggest they play it to understand why government regulation and military protection of traders and merchants leads to vastly lower costs to society, and to see first hand how far the effects of market manipulation can travel.

    And you're leaving out another critical component of Eve that isn't at all like the realworld: You're never sure who you're trading with. Identities can be traded, and because of this, and the interface mechanics, you can be buying supplies from your enemies one day, and selling arms to them the next.

    And all of this "free market" love makes people incredibly distrustful, very manipulative, and economic power equates directly with military power. And what's more interesting... the distribution of wealth looks pretty much like it does in the United States: 1% controls over half the total wealth in the game... and that 1% can be very petty, self-centered, and short-sighted. Kings and kingdoms alike are created and destroyed every day -- there is no stability. In nullsec, you always have an exit strategy... a way to burn your assets and get out quick, because if the enemy doesn't fuck you over, your would-be kings claiming to be on your side will.

    Eve is the wild-wild west, seen through the lens of a hundred spreadsheets. When it's a game, this can be fun. When it's real life... do you really want to go to bed one night and wake up the next with your house on fire and your neighbors looting each other, you, and everything else as the next Great New Power rolls in? Because this is a frequent occurrance in the game.

    HFT isn't a system stability problem as much as it is an access problem. What it does is increase the cost of entry into the market -- those who don't engage in HFT wind up paying for those who do, and so it winds up penalizing people with smaller portfolios and shifting the costs of it onto them. What you need to understand about profit is that it is always at the expense of someone else. And HFT is the sublime example of how to nickle and dime the less fortunate to death. These fractions of a penny here and there add up because it gets compounded by interest rate. Over time, the spread between those who have it and those who don't will grow; As is the trend in any investment-based system.
