I think you've hinted at the problem. There's little difference (especially now) between a description of an object and the object itself. If I were to design a new brake on paper and then implement that brake with steel and rubber, would I lose my right to patent the device because the transition from CAD to physical realization is obvious? When the patent system was designed the distinction between the abstract and the concrete was fairly obvious. Once we invented devices that could encode ideas and turn them into things we started running into problems.
I appreciate the argument, but it seems like it would invalidate pretty much every patent. (Including drug patents because drugs are designed in silico, so perhaps it's a net positive.
I think there is general agreement that if a person were to encode a program in silicon (i.e., as a custom chip), that invention would be patentable. Now let's relax the physical implementation: Can we patent a program that relies on programmable chips - that reconfigures the hardware on the fly? If not, why is this program any different than the original program? Why must the program be fully hard-coded to be patentable?
Relaxing the implementation details even further: Can we patent a program that relies on general-purpose hardware? If not, why is this program any different than the one that uses programmable chips?
I confess that I am uncomfortable with software patents, but I'm willing to acknowledge that I lack a firm basis for my unease.
AFAIK the term is derived from the Dungeons and Dragons roleplaying game.
In the Dragonlance series of books, the various classes of mage were dressed differently depending on their nature. Good=white, neutral=red, black=evil.
I think that's wishful thinking. It arises from blue-team (us, i.e., the good guys) vs. red-team (us pretending to be them, i.e., the bad guys) military exercises. In other words, a red team is a bunch of good guys pretending to be bad guys against whom the blue team can practice.
The only way state outcomes are non-independent is if one state's polls close earlier and the results are announced before another state's polls close. As far as I know, this influence is not part of Nate Silver's estimate.
This is not correct. As others have noted, two states' outcomes can be non-independent if some common cause is at work. For example, my grass being wet and not being able to see the sun are non-independent, not because wet grass induces darkness, but because there's a common cause (rain-clouds) that can influence both events. Once you account for the common cause the events become conditionally independent. In this case, if one poll is biased against Romney, then it is likely that other polls are also biased (and non-independence holds).
Based on the offers I received upon earning a Masters in Computer Science, I would probably be a little better off financially if I had joined the work force at that point in my educational career. Instead, I chose to earn a PhD (in Computer Science). I do not for a moment regret that decision. The degree affords me a fair amount of intellectual freedom (even though I work for a corporation).
The degree certainly does not guarantee a posh research position at MSR (or a similar lab). But, it does demonstrate an ability to think independently and critically, which are skills still valued in the workforce.
Finally, I would note that every CS PhD that I know is gainfully employed, and only one feels under-employed (although a delay in earning the PhD due to an advisor problem didn't help). So, my advice (FWIW) is to go back to school, provided that you are motivated more by novelty (intellectual freedom) and less by money.
This is largely good advice. However, student loans are not necessarily a bad investment. You are correct, though, that you need to take your education seriously, or it's a waste of money.
Paying off a mortgage quickly may be a bad strategy provided a) your rate is low (say 5%) and b) your employer provides some level of retirement matching (say 10%). Not only do you get to claim the mortgage interest as a tax deduction, but you're getting an automatic return on your retirement investment. So, my advice would be to pay the minimum amount on the mortgage and invest that money in a retirement account.
Paying for things with a credit card is not prudent. But, if you have a no-cost card with some sort of reward program (e.g., I can use points to obtain gift cards for groceries), paying with credit can save you money. The trick is to always pay the card in full. Even one late payment and the strategy fails big time.
Well, we know plants frigging *LOVE* the stuff... so if we don't we can probably anticipate higher crop yields.
Unfortunately, it's not that simple. For example, increased temperatures will stress food crops. More information is here.
They said the oceans would rise by 2009.
But so far, the models created based on the presumption of the association keep breaking down and their predictions don't play out as expected.
Again, this assertion doesn't stand up to scrutiny. Models successfully reproduce global temperatures.
