    In theory, life on this planet is an absurd idea.

    Are you saying that in theory, life is unlikely here?

    What theory actually says this?

    Think about it: we're on the fringes of the galaxy, out in the boondocks...one of the emptiest, coldest, and darkest part.

    Well, no, not really. We're pretty close to a reasonably warm star. Given the evidence, if seems that our distance from that star is more important than its distance to other stars.

    If anything, life would be most likely to exist closer to the core.

    Why?

    What theory says that being in an area with higher star density would be more conducive to life?

    I can formulate several theories to explain why being close to the "core" is worse:

    Too much radiation.

    Too much heat.

    Too high a density of "renegade" objects (like comets and meteors), preventing a stable ecosystem from forming on a given planet. ...

    There is no requirement that a corporation make money, or that if it does that the shareholders get paid any of the profits. There is no requirement that the board of directors be composed of shareholders at all, let alone those with large percentages of the voting shares.

    The board of directors and the officers have a fiduciary responsibility to the shareholders. This means that they must use the investment money responsibly, and should actually be trying to earn money for the company and the shareholders. The laws are basically there to prevent someone from starting a company, getting investment money, and then "losing" all of it due to poor decision making (paying themselves all of the investment money as a salary, for example).

    Even if there were a requirement to maximize profits, that is a vague phrase. Maximize over what time scale? A financial quarter? A year, a decade, a century ...? You can't spend any money on research if you're maximizing for the quarter, but it sure helps in the 10-100 year time frame. Spending money on clean-up technology is a bit like paying for insurance. Neither is a good investment until something bad happens.

    Of course none of this prevents shareholders from suing officers and directors, but that's not because they actually have a good reason to.

    The resolution of the machine is irrelevant, it's the tool size that matters. If you have a 1/2" diameter end mill, you cut a 1/2" swath through the material. It makes no difference if you have 0.01 inch resolution or 0.00001 inch resolution, you'll still step over by about 1/2 inch when using that tool.

    So you can see how optimised tool paths, and so on are literally god when it comes to CNC.

    Yep, for production machining, optimized toolpaths are a very good thing. The common limiting factor for small machines though is spindle horsepower. The machine can only remove so much metal per hour, and that's directly proportional to the spindle horsepower. It varies with many factors (cutter material, cutter coating, cutter speed, coolant/lubricant, etc), but it's the thing that limits the depth of cut you can use for a given end mill. There's also no such thing as an "optimal path". There are many factors that determine what may be optimal in a given situation - surface finish (the look of it), surface roughness, tool life, machine rigidity, and more.

    Sure, there are free OS alternatives to the stuff I paid for, but I don't have the time left to live, nor the inclination to pay the electric bill, that using the free OS alternatives requires.

    I sure hope you're talking about non-optimal free CAM, because as it happens, the most capable machine controller available (for less than $5000) happens to be the open source one.

  8. Re:Shouldn't the OS handle this? on IE9 Throws Down the Hardware Acceleration Gauntlet · · Score: 0, Redundant

    It's just the definition of an operating system, that's all.

    The OS is there to provide a standardized (for that OS - not necessarily across OSes) interface to hardware resources. This includes memory, disk space, CPU time, and of course user interface hardware.

    If there were no OSes, everyone would have to include e.g. filesystem software within any program that wanted to use the disk drive. The whole point of Windows was to insulate the programmer from the hardware - you use the same GDI calls whether you have a Diamond, 3dFX, Number Nine, or Matrox card (back in the old days). The driver and OS insulate the application from the specifics of talking to the hardware.

    Video games are a bit of a special case, because they are the most performance-limited applications most people see. For most applications, there should be no need to know anything about the hardware implementation - only its capabilities (resolution, color depth, etc). The OS API should insulate the programmer from having to know the details of the underlying hardware. For specific applications though, where the highest performance is needed, the application needs to just reserve the hardware resources and ask the OS to get out of the way. Databases need this for memory and disk management, and video games need this for graphics hardware. There shouldn't be a need for a browser to get to this level.

    In the case of government run health care the government loses money when it treats people who are sick.

    Fixed that for you.

    Actually, this is the case with private insurance as well.

    In the course of debate, people have talked about how the insurance companies are necessary to keep the cost of medical care low. In fact, it makes no real difference what the actual caregivers receive, it only matters how much the insurance company pays out.

    Profit = income - expenses.

    The insurance companies lower expenses by not approving treatments, as well as contracting lower payments for treatment. There was a recent report (I don't have a link) discussing the effect of low insurance contract rates on the rates for everyone else. The gist of it was that the low rates the insurance companies pay for services are subsidized by the much higher rates others pay. When everyone has insurance the rates will have to increase, because there will no longer be a pool of high-paying uninsured.

    I think what people keep forgetting is that we have a system that rewards companies (hospitals, doctors, insurance) for not making people well. In my view, hospitals shouldn't be for-profit institutions. I'd generalize that actually, any business that isn't necessary in the ideal case should not be for profit. (think fire departments - the best case for a fire department is if they can educate people and prevent fires) There's an incentive to create or prolong problems when your business is based on treating those problems.

  16. Don't use software on Best Open Source Business Tools? · · Score: 1

    A few people have said it already, but I'd like to reiterate:

    Don't expect software to be able to do this for you. Tax laws change every year, both federal and state. Requirements for corporate filings change every year. Payroll requirements change every year (withholding amounts for FICA, FUTA, unemployment, health insurance requirements, etc).

    I have an S-corp, but I don't do any of this myself.

    I have a payroll service that costs $50 or so per month. For that cost, they do direct deposit, tax withholding, and also file quarterly 941 forms and prepare W-2s at the end of the year. All deductions are calculated by them, and their guarantee is that if they make a mistake, they take liability for it - ie, they'll pay any penalties or interest that arise as a result.

    I have a lawyer who charges less than $200/year to prepare corporate filings. Additionally, they provide me with a list of changes to corporate laws over the course of the year. They highlight anything that may be important for me as a small business owner.

    I have a CPA who prepares the corporate tax return. I do the day-to-day accounting (I happen to have Peachtree for Windows, I couldn't find anything open source or Linux based in 2000 when I started this business), but the CPA checks things over and prepares the corporate return and shareholder K-1 forms. This costs about $1000/year.

    Overall, I pay roughly $2000/year for all of these services. I think this is well worth it, since I not only don't have to spend the time actually doing this work, but I also don't have to spend the time learning how I need to do it differently every year. I also get some measure of effective insurance, at least with the payroll company, since they are responsible for any mistakes they might make (they haven't made any yet).

    I note that most of the question was really directed at legal questions. You can certainly get boilerplate contracts from several places. You may want to find a local lawyer and have them write you one. Get a confidentiality agreement, a subcontractor agreement, and a contract for services (that you provide). Once you have those, you can essentially reuse them for future contracts. There aren't a lot of requirements for meeting minutes (though one thing you should watch out for is that you are required to send a notice of shareholder meetings some 30 days before they're scheduled, or you need to have a "waiver of notice" form signed by all the shareholders. Of course this may not be true in your state) - just a list of people present, a very simple list of topics covered (summaries of the conversation are good, but are not necessary), and the dated signatures of the corporate secretary and president, who in my state can't be the same person.

    The bottom line is that there is a lot of expertise needed to do these things right and keep up with all the annual changes. The cost of hiring experts is not that high, so it should be pretty close to a no-brainer.

There will be a flood of Android hardware out soon in addition to the G1 and at least some of it will be hackable or open enough for developers to delve into the stack if they want. For example, you'll be able to improve the hardware drivers, add functionality left out by the original makers because they feared patent infringement, and take advantage of hardware acceleration that didn't make it into the shipping product. Perhaps the only sacrosanct portion kept off limits will be the radio stack itself, which if hacked could invalidate the CE mark, FCC, GCF, PTCRB, etc.

    The following is from a great book by A.K. Dewdney: Yes, We Have no Neutrons.

    For which:
    R* = number of new stars that form in our galaxy each year
    Fp = fraction of stars having planetary systems
    Ne = average number of life-supporting planets per star
    Fl = fraction of those planets on which life develops
    Fi = fraction of life forms that become intelligent
    Fc = fraction of intelligent beings that develop radio
    L = average lifetime of a communicating society

    The formula has appeared in several popular science magazines with the values set to:

    N = 10 x 1 x 1 x 1 x 0.01 x 0.1 x L

    So, N = 0.01 x L

    The only numbers in the formula which anything other than a guess can be made are R* and L. Based on current observations most set R* at 10. Everything else in the formula would be a wild guess, except for L. More is known about L than any other part of the formula, since we are a communication society. Since we receive more and more of our communication from satellites, cable, and the internet, we are broadcasting less and less away from the earth. In the near future we will likely go dark as a significant source of radio/broadcast signals capable of being detected from space. If we say that our source of signals is about 100 years, drop the 100 back into the formula and you get 1. That must be us.

    You have a slight units error in your analysis.

    R* x Fp x Ne results in the number of new life supporting planets *per year*.

    Multiplying the next three terms (Fl x Fi x Fc) gives us the fraction (or probablility) of those planets that will eventually have intelligent life.

    So, to get the number of coexisting societies per galaxy, you can more or less take the number of new societies per year and multiply by the number of years during which those societies will be able to detect each other (L). The number of new detectable societies (with your wildly optimistic probabilities :) ) = 1.

    That's not 1 technological society ever, that's an average of one in existence for any given year, in our galaxy.

    There can be many many civilizations that rise and fall, and never know each other, over the course of billions of years.
