    How much can you spend in a year as an individual? Simple; your gross income, plus any new debt you take on.

    How much debt can be issued to the entire economy in a year? Is it limited to savings? Nope. Banks issue loans against the assets you have. And through the magic of double entry book-keeping, the loan creates a deposit. Reserve requirements don't limit new debt, mainly because banks look to fulfil their requirements from the reserve bank one month after the loans have been created.

    How much spending is there in the entire economy? Total income (GDP) plus growth of debt.

    How much growth is there in the economy? Well that would be income growth (velocity of GDP) plus acceleration of debt.

    Unemployment, asset prices, and economic growth all show a very strong correlation to the acceleration of debt. And the correlation is very strong when debt levels are high.

    So why are we in a financial crisis? Well the debt bubble leading up to 2008 slowed down and then reversed. In 2008 there was an absolutely massive deceleration in the level of debt. This triggered an absolutely massive shrink in spending, in the US spending in one year shrank by almost 2 trillion dollars. Since then conditions have improved a bit. The level of debt is still falling, but the acceleration is positive.

    To fix the economy, with the least pain possible, we need to keep the velocity of debt negative. With the acceleration level of debt averaging just below zero for around 10-15 years, until the level of debt has drastically reduced. Any sudden drop in the acceleration of debt will indicate a crisis, any jump in the acceleration will indicate a bubble.

    Or we need to write off the debts now, which would require a massive coordinated effort from governments to restructure the entire economy. A process that would disadvantage one section of the economy more than another no matter how it was done.

    SCTP's a neat protocol. But by itself, it won't help to accelerate HTTP. SDPY is designed to quickly load all of the different resources you'll need to render a web page with a much lower latency. Standard HTTP over SCTP wouldn't have as much of an impact on latency.

  8. Re:Better link on Linaro Tweaks Speed Up Android, By Up To 100 Percent · · Score: 2

    If this demo was waiting for a screen repaint before drawing the next frame (and since there's no flickering it's either doing that or triple buffering). Then if the cpu can paint the screen at 65fps, but your monitor can only do 60fps, then the demo will run at 60fps. However if the cpu can only paint at 55fps, then the demo will actually run at 30fps. eg each frame will be displayed by the monitor for 2 screen refreshes and the demo will take twice as long to run.

    That's the point I was trying to make. That if you are waiting for the monitor to paint each frame, a small difference in rendering speed can cause a large difference in fps.

  9. Re:Better link on Linaro Tweaks Speed Up Android, By Up To 100 Percent · · Score: 1

    30fps vs 60fps? The speed difference could actually be very minor. It could be simply that the google version just misses a screen refresh and waits for the next one, where the linaro version doesn't. Obviously there's no doubt that it is faster, but a single fps number doesn't give you all the details.

  13. Re:Ha! on Hacked Bitcoin Financial Site Had No Backups · · Score: 1

    Just remember that when the money supply shrinks, your debts are worth more.

    Some time around 2008, the rate that new loans were being issued plummeted. And the value of existing loans dropped as well through repayments or bankruptcies.

    This is the real cause of the problem with the economy. Not that the supply of cash (M0 - M3) is rising, but that the supply of credit money, issued by banks, is shrinking *fast*. The US Fed's recent attempts to "print money" are about 20x too small to touch on the credit money that is being destroyed.

    Deflation is nasty, especially when everyone has large debts denominated in that currency. As everyone tries to pay down their debts, the velocity of money shrinks reducing incomes. So in real terms your debt actually increases. The more you pay, the more you owe.

    I've worked on quite a few large-ish database applications (eg 800 - 2000 tables, some with multi-million rows), and I'd say I'm fluent with SQL. But the thing that annoys me most about SQL, from a maintenance perspective, is how much of the database structure ends up strewn around in your code base. SQL is *not* good at encapsulation.

    When a new requirement comes in that should cause you to change some of the primary relationships in your database, you have a look at how much code you'd need to change to do it properly, and end up just hacking in something really ugly instead. Maybe you should be able to use a foreign key, or many-to-many join table relationship, just by using its name (or something like that). Instead, every query must list the entire set of columns involved. And often provide hints to the database engine on which indexes to use first.

    And the problem gets much worse if you build your schema "properly" and heavily normalise the structure of everything. Because then any "simple" query easily involves 7 tables. And you probably need to code it into a stored procedure so you can build the data manually in a temporary table, since the database engine can't choose the right indexes and processing order and ends up scanning through millions of records to find the half dozen you actually wanted.

    Sure you could write a set of classes to build the SQL query strings for you, so you can encapsulate these details in one place. But then you'll probably end up with an ugly inner-platform that only the original designers really understand and your skills with using it wont translate directly into any other application or language.

    I'm not saying the NO-SQL folks have reduced any of the complexity of working with large complicated data sets. But SQL is not the silver bullet you make it out to be either.
