  1. Re:it's too fast on More Warnings About High-Frequency Trading · · Score: 1

    Seconded. This came up in a previous discussion, but I've been unable to find any resources on the web discussing the idea.

    I'm advocating a much longer quantum, maybe 5 or 30 minutes. The longer the quantum, the more level the playing field.

    As a point of reference, (some?) electricity markets operate on half-hour trading periods. Everyone pays the same spot price for that period.

    One detail that I'm mulling over is whether market depth (orders entered for the coming period) is made public in real time or not. Putting incoming orders in a 'sealed envelope' until bidding closes seems reasonable. Why shouldn't the market have to keep a few secrets when everyone else (insiders, brokers, etc) has to?

    It makes a difference for corporate actions like capital raising and leveraged acquisitions.

    A high share price is defensive against being bought out.

    A high share price keeps investors happy. Unhappy investors could kick out directors, refuse to participate in capital raisings, etc.

    A high share price directly benefits employees and directors who hold shares or options, and make decisions on behalf of the company.

    The limitation is that provided you hold sufficient shares, you can buy and sell shares with impunity since the shares you buy are deemed to be different from the shares you sell. The shares you sell are always the ones you've held the longest.

    For example, if I hold one million shares in a particular company and trade in lots of 100, I can carry out 10000 buy and sell orders on a given day before I run into the one-day limit.

    If HFT traders don't hold enough shares themselves to circumvent the rule, they can just borrow from (or partner with) someone who does.

    TFA is talking about food riots. People will run out of energy for rioting a long time before they die of starvation.

  5. Re:Still Wrong on Complex Systems Theorists Predict We're About One Year From Global Food Riots · · Score: 1

    Predicting that our food supply will limit our population isn't the same as predicting that vast numbers of people will drop dead of starvation. That'd only happen if the food supply collapsed; it'd take insane population growth rates to have that effect due to a change in demand alone.

    More plausibly, fertility rates decrease as the population approaches equilibrium with food supply over an extended period. That is to say, people don't die of starvation, instead they aren't born in the first place, or die in infancy.

    Or just 'Let the thing run'.

    There's nothing here to indicate that the de-duper referenced in TFA actually failed, and a week or more doesn't sound unreasonable for that amount of data.

    I'm currently going through the same process on my NAS. The first step was to gather a table of filenames and checksums, as suggested in first post. This can take a long, long time.

    The next step, which I'm still tackling, is to do something with the duplicates. If you're actually deleting files (as opposed to replacing duplicates with hardlinks to the same file), this pretty much has to be manually-guided or you risk majorly screwing up your data (hint: some files are duplicates for a good reason).

    I was pretty young at the time, so forgive me if I have this completely back-asswards.

    We (as in, the Labour government of the day) had the balls to stand up to the US on the nuclear issue because it was an easy fight and a popular diversion from the simultaneous caving in to US/global interests on matters of the economy and economic ideology.

    I have all respect for David Lange as a folk hero, but let's face it, his government sold us out.

    As a fellow NZ'er, can I balance that by pointing out that we have one of the best-functioning democracies on the planet.

    We have a fair electoral system in MMP. Nearly everyone's party vote counts. And we're continuing to improve it, with the lowering of the threshold vote from 5% to 4%, and the removal of the awful 'coat-tails' rule.

    We have a low level of corruption. Case in point: National MP Pansy Wong was shamed into resigning after her husband had a business meeting while on a taxpayer-funded overseas trip; it must've been front-page news for weeks!

    We have campaigns that aren't spend wars. The two main parties spent around $2M apiece on the last election, which didn't even test the spending limits that were in place.

    You don't have to be rich to get elected. John Key happens to be wealthy (~$50M net worth), but that's an exception, and doesn't explain why he was elected.

    Now, what we don't have is mainstream media and voting public engaging their critical faculties come election time. And so neither do the politicians. But that's not the system's fault.

    We have to reign in the meddling before 'throwing the baby out with the bathwater' becomes a literal expression.

    I loved watching the Olympics because it teaches that diversity trumps equality. It's refreshing in our PC-mad world (everyone is equal, to differentiate is to discriminate) to see how it plays out.

    Women don't compete with men. Why not? Well, imagine if they'd introduced mixed boxing instead of women's boxing.

    And for once people get it that this doesn't imply men are superior. No one is suggesting that should improve our gene pool by getting rid of women.

    Some sports are dominated by this or that racial grouping, but it's clear that this is about body type specialization, and not due to (some general notion of) racial superiority. The athletes winning the marathon aren't contenders for the dash, and neither group are going to be champion weightlifters in their spare time.

    No matter how much genetic engineering you throw at the problem, the best specialists will always beat the best generalists.
