    Despite common perception, the IRS is actually pretty reasonable to work with, if you're not trying to cheat them out of their Congress-determined fair cut.

    The difficulty comes in determining exactly what that fair cut is, given all the many ways to get income, and the many more ways to hide that income.

    So in other words, you want your juries to be vigilante posses, who determine guilt not by impartial facts, but by prejudice and bias, simply repeating the verdict handed to them by the Court of Public Opinion. You'd be right, though. With that kind of jury, you don't need to have any legal education to argue a case. You just have to slander the other guy convincingly enough while confirming the jury's prejudice.

    1. Clearly, making a violent video game is worthy of punishment, because all the parents on the jury can see the connection between their teenagers' gaming habits and their recent distant attitudes.
    2. Obviously, this man is not a rapist because the woman accepted his offer of a drink. As all the barflies will affirm, that's a binding social contract.
    3. This white man should go free, because setting a black man on fire is free expression guaranteed by the First Amendment.

    Where exactly do you draw the line regarding which biases are acceptable? Which school of thought regarding "constitutional law" are jurors allowed to know about? After the complete injustice of the Zimmerman trial, would a similar trial have any chance of justice, were it tried on preexisting "knowledge" rather than the facts of the case?

  6. Re:Ponzi scheme on Cryptocurrency Exchange Vircurex To Freeze Customer Accounts · · Score: 3, Interesting

    In a Ponzi Scheme, the founders persuade investors that they’ll profit. Bitcoin does not make such a guarantee. There is no central entity, just individuals building an economy.

    So they're not promising anything, therefore they can't break their promises. This does not affect anything about how the scheme actually works.

    A ponzi scheme is a zero sum game. Early adopters can only profit at the expense of late adopters. Bitcoin has possible win-win outcomes. Early adopters profit from the rise in value. Late adopters, and indeed, society as a whole, benefit from the usefulness of a stable, fast, inexpensive, and widely accepted p2p currency.

    This assumes that the "usefulness" actually exists and is beneficial. So far, Bitcoin hasn't been stable, fast, or widely-accepted, so the win-win scenario they propose isn't actually possible. I can just as easily say that by everyone giving me all of their money, society will benefit because I will donate everybody's money all at once to a charity, reducing the charity's overhead costs.

    The fact that early adopters benefit more doesn't alone make anything a Ponzi scheme. All good investments in successful companies have this quality.

    This is true, because the FAQ writer doesn't seem to understand what a Ponzi scheme is in the first place. In a Ponzi scheme, the investment capital of latecomers is used to pay the returns of the early investors.

    When you invest in a company, your money is pooled with everyone else's to run the company. The company also has a pool of profit, which is often split proportionally for dividends. You can also get a return by selling your stake in the company to someone else who wants to be involved. At no point are investments used to pay out returns to earlier shareholders.

    Bitcoin as a whole fits the Ponzi scheme pattern, because at the exchanges the money used to pay off the early miners comes directly from people now buying coins. Since the Bitcoin market is so much smaller than the price of the Bitcoin supply, the main mechanism that external value comes into the Bitcoin economy is by investors trying to get into the scheme for its high (not-guaranteed) returns.

    The only real distinction between a Ponzi scheme and Bitcoin is that Bitcoin has no single master, that we know of. Ponzi schemes usually have a single person or small group promoting the investment. Bitcoin doesn't have any organized leadership, but rather relies on the self-sustaining marketing buzz of zealots. That makes it a better fit for an economic bubble, rather than an actual Ponzi scheme.

I'm going to assume that the problem in the picture is actually demonstrating an aspect of the transitive property.

I've seen it often in conspiracy theories, where a series of images, statements, and facts are presented without context to outrage the audience, then the author's theory is presented as the only context where everything makes sense, rather than allowing for each item's individual context to be understood first. It's common enough that I feel there must be some literary term for it, but I don't recall any.

It is a mechanism for a purpose, and a thing of importance to be studied.

    Consider similar exercises for other subjects. The first exercise in many programming languages is "Hello, World!", for the purpose of showing a minimal program that doesn't use any special features of the language.

    Once exposed to a concept, the additional time spent coloring or reviewing strengthens the connections to related concepts. When coloring the minute hand, the student remembers that each number the minute hand passes represents five minutes. The Hollywood idea of rapid learning doesn't work too well in reality.

  15. Re:While I expect foul play... on MtGox Finds 200,000 Bitcoins In Old Wallet · · Score: 2

    Never one to assume malice, my guess is that it was a temporary wallet used for short-term transfer of funds. Back when I worked in finance, we fairly often set up accounts for a few days, just to receive an incoming transfer or to send out funds from the right name. Those accounts, by their published nature, became targets for attack. It was always enlightening when a client sent in an emailed request to withdraw money from the temporary account, after we'd just closed the account as planned a few days before.

    Similarly, I'm thinking the wallet was opened, used, then emptied, but stuck around on their servers. It'd make a convenient place to hide stolen coins (regardless of who stole them). Those malleable transactions could be used to skim coins and push them into the wallet. If noticed, any investigation into the wallet would reveal that it was just an internal account, conducting low-volume business as usual. The thieves could then transfer the coins out at their leisure, in small similarly-innocuous amounts.

    Then everything collapses, and the company faces bankruptcy. Step one is to look at every asset the company has, and figure out whatever value it may have. Naturally, that would include explicitly checking each wallet, rather than just relying on what the database says the balance is. Lo and behold, one wallet has coins still in it, and the company might have assets to cover its debts, which is exactly why that search is the first step.

  16. Re:Shortage of people or people with degrees? on The Myth of the Science and Engineering Shortage · · Score: 1

    Consider that to be an engineer requires 4 years of 'work' during high school (unpaid). 5 years of college (also unpaid and requiring taking on debt). 2-3 years work experience. That's probably an investment of 15000-25000 hours. An investment worth 3/4 to a 1.25 million dollars. Certainly a 5-10% return on investment is very reasonable right? Well that's 50-100k per year.

    Checking the math...

    Let's assume 50 40-hour productive work weeks each year. High-school work isn't as good as college, which isn't as good as professional work, so we'll assume wages of $10, $20, and $30, respectively.

    High school is 4 years * 50 weeks/year * 40 hours/week * 10 dollars/hour. That's $80,000. College is 5 years (assuming a 1-year master program) * 50 weeks/year * 40 hours/week * 20 dollars/hour. That's $200,000. A fresh graduate therefore has invested $280,000 in time with no return. Then they enter the workforce, and start getting the return.

    The entry-level position is 3 years * 50 weeks/year * 40 hours/week * 30 dollars/hour. That's $180,000, but the subject is actually being paid for their time, now. Rather than adding that to the investment cost, that's the first three years of returns. We'll extrapolate that out for further insight.

    After a total of five years in the workforce, even without any raises, the investment is fully reimbursed, and any additional returns are profit (reaching 7% ROI in ten years). In contrast, the employee could have simply dropped out of high school, and worked at $10 the whole time. That comes out to $20,000 per year, compared to the college track now earning $60,000 per year, so there's a profit of $40,000 per year for a college education.

    With the initial investment cost of $280,000, the time investment in college is recouped in 7 years. Add a $40,000 investment cost for tuition and other expenses, and the investment is recouped in 8 years, still assuming a constant $60,000 income.

    Of course, then there's taxes. Interestingly, since taxes aren't being paid during schooling, that actually lowers the relative value of the time being invested. Rather than an education costing $280,000 in lost income, it only costs $168,000 in post-tax lost income, assuming a 40% flat tax. Even with the lower take-home pay rate, that cost is recovered in only six years, and after ten years the ROI is 11%.

    Your estimate of $50k to $100k to get a 5% to 10% ROI is close, but extreme. The low end of the salary range puts you in the high end of the return. However, the estimate of $750,000 for an education doesn't seem to make sense. Perhaps that's why a 6-figure salary for every employee seems unreasonable to the political and management folks - they've already done the math.

    Of course, math is only a part of the issue. The costs and profits involved here are assuming that $10/hour is an acceptable baseline for wages. We've assumed that without a high school education, a baseline employee could sustain a $20,000 annual income, but we have not considered whether this is a suitable income for an acceptable standard of living in the modern age. That, however, is a discussion for another time.

    No, no, no, and no.

    The single biggest problem with PHP is the tendency for old code and old programmers to keep their bad habits around when moving to new projects. PHP lacked vital modern features (like static typing and namespaces) for so long, and it's evolved so many workarounds (like magic quotes), that programmers have learned the wrong way to accomplish basic tasks. Now they have a new language, supporting the right way to do these things... but the old and broken ways still work. Sure, there will be a few programmers that will use the new way and be thrilled about the good technique, but then time crunches will set in, and code reviews will be rushed (or nonexistent), and those old ways will creep in, bringing the bugs with them.
