    "It's fine that you think that, but can you provide some evidence to me so I can change my mind if I'm wrong?"

    I was disagreeing with your statement, and then I gave the explanation why. It's impossible to give evidence about the sexual practices of humans pre-agrarian. Yes, there are hunter-gathers in the world today, but we cannot say they deal with sex and reproduction in the same way.

    "As long as the nursing mother is exclusively breastfeeding, (nursing frequently day and night with no supplemental feedings), the baby is younger than 6 months of age, and the mother has not started having periods, she is more than 98% protected against pregnancy. This period of exclusive nursing means not only no supplemental feedings of water or formula, but also little or no pacifier use. All of the baby's sucking needs are met at the breast, which means demand feedings around the clock. As long as the mother has had no vaginal bleeding after 56 days postpartum, and the baby receives no supplemental feeds, she has only about a 2% chance of becoming pregnant (this compares to the combined birth control pill, which is about 98%-99% effective if taken every day without missing a dose)."


    And from another source...
    Can I get pregnant while I am breastfeeding?

    The short answer is "Yes." It is possible to get pregnant while breastfeeding. However, breastfeeding can be used as part of your family planning technique. As a matter of fact, if you can answer yes to the following three* questions, your risk of pregnancy is less than two percent.

    1. Is your infant less than six months old?
    2. Are you amenorrheic, that is, are your menstrual periods absent?
    3. Is your baby breastfeeding around the clock without receiving other foods, beverages or pacifiers?


    I also disagree with your statement "They know that caring for children takes a lot of effort, and that more children means less likelihood that any individual child does well." I'm thinking that caring for children in a hunter-gather tribe consists of "Feeding", "Shelter", and "Socialization". Feeding is easy, it's done at the group level. You said it yourself that they only need to work 2-3 hours a day to provide for themselves. Shelter, you have to make some clothes and something to shelter from the elements. Socialization. Teaching the kids may take some effort at the beginning of the family, but the kids will learn from each other, and you can have the older kids take care of the younger kids. So, where's the effort? If it's such an effort, and they have those primitive BC methods, why have more than two or three kids?

    Here's another biological fact, women cannot have a baby if their body fat goes below a certain percentage. One of the problems of the hunter-gatherer societies is that sometimes there's nothing to hunt. They had to migrate just to survive. When you're not getting enough food to build up a fat reserve, birth rates will go down.

    Fact, calories don't come from nowhere. If you're breastfeeding, and you become pregnant, your body will have to support the creation of a new baby plus convert enough calories to support the existing baby. Sometimes you won't get enough calories. You weaken, both babies weaken, survival rates for all involved go down.

    So, lets look at what we have here:
    My facts:
    1. Breast feeding is a natural birth control. It doesn't last forever, (and is unreliable past 9 weeks) but when you add up the time over a mother's life, there will be years in her lifetime where she's not pregnant and infertile.
    2. Hunter-gatherer tribes are completely at the mercy of finding animals to hunt and edible plants to gather. Since they migrate, they can't store food for very long.
    3. When you can't find enough food, humans (And all life I've heard of) have built-in safeties that prevent them from spending calories on creating babies.

    Your facts:
    1. Some guy found a modern hunter-gatherer tribe where the women know how to get guys off without having sex.
    2. Agrarian societies have higher birth rates than hunter-gatherers.

    It's sad how some people romanticize primitive societies.

    Ahh. I had to look it up to be sure. I don't think "Hunter-garther women try to limit the number of children they have to care for."

    The same hormones that make milk suppress the release of reproductive hormones in women. While breastfeeding full-time most mothers do not ovulate and do not have menstrual periods.

    So, farmers have more kids because they bypass the natural inhibitor by feeding their babies alternate foods.

    You still can't make beer out of a dead woodchuck though.

    Hunter-gatherers work about 2-4 hours a day to meet thier needs. Why would someone give that up to work 8-12 hours a day for some payoff in another season?


    Because you can't make beer out of a dead woodchuck.

    On a more serious note, because farming is more dependable, and causes less wear and tear on people, than hunting and gathering.

    You said it yourself, farmers have more children. Do you really think they reproduce more, or that their children have a better survival rate?

    28 days! Pshaw! You're just *inviting* the bad guys into your system if you follow such a lax plan.

    Every day should start out with changing your passwords. You may have to hire a few more people who's job is to reset forgotten passwords, but when you have to do it constantly it shouldn't take more than a minute per person.

    Of course, if the bad guys learn that everyone changes their password in the morning, it wouldn't take much effort to be in the right place at the right time and get unrestricted access to the systems for 24 hours.
    So you'll want to back this up with some sort of bio-identity methods. Fingerprint identification, retina scans, and instant DNA testing.

    Some people say that these aren't secure enough, that someone can get fingerprints, a DNA sample, and a picture of your retina. There is an easy solution to this if you just think about it, the daily random mutation of all your employees before they change their password and give a DNA sample.

    Anything less than the method outlined above simply isn't secure.

    Don't worry about it, when the tests are done, they cure the arthritic mice, put the anti-seizure chip in the epileptic mice, and tiny little bionic eyes in the blind mice.

    Did you look at AMD's earning's statement? They made a profit, but compared to all the income they brought in, it wasn't much in comparison.

    I was also dissapointed at the 800$ 4800X2, but from looking at their statements, it looks like the X2s just cost more to make.

    Intel can price their dual core cheaper because they're using the new 62nm fabs. The cores take up less space on a die and therefor cost less to produce.

    It's interesting that it took a (multi?)billion dollar fab for Intel to catch up to AMD. Once AMD gets their's up and running, their product will smoke anything Intel has out.
