    Why was this the "birthday" and not when two machines were first connected to eachother?

    Simple. This was not the first time two hosts were connected together via a serial line. If you only cared about that, you'd have to go back a lot farther. Heck, the first modem dates back to 1962. What made the Internet possible was not the notion of having computers that could talk to other computers. The key change that made the Internet possible was the notion of all the computers speaking a single language and having routers that knew how to pass messages on to other routers, eventually to another computer. That was not realized until the first packet was sent on a packet-switched network, which in its most primitive form, occurred on October 29, 1969.

    Another problem with handwritten notes is that many people experience serious hand cramping after writing continuously for an hour. I could type for a week without getting tired; you don't have to tightly grip a keyboard. I stopped writing stuff by hand entirely back in junior high, with the exception of a couple of teachers who didn't like typed stuff. Handwriting is just too physically draining for what you get out of it. Pen and paper are for *short* notes to myself, marking up copy, etc. Everything else is 1s and 0s.

We do this in meetings at work for the same reason. Alternatively, professors who use electronic slides can provide a copy of them electronically, removing the need to waste a lot of the students' time hand-writing copies of the same content unnecessarily.

    Some people might think that. It really means that the jump is very sudden, regardless of how big it is. That said, by definition, most sudden jumps are big, or else we wouldn't perceive them as a jump, so that's not a particularly surprising interpretation.

    Even though we both have similar concepts of what the learning curve is referring to, I think the GP's interpretation is backwards, at least from a user interface design perspective. If the learning curve is steep, that means you learn a lot at the very beginning, which means that you have to learn a lot just to get started. Otherwise, you wouldn't have bothered to learn all that stuff up front. Thus, a steep learning curve means that the UI is relatively hard to learn, even if it doesn't take you a huge amount of time.

    The ideal learning curve for software is actually fairly linear; the amount you learn at the beginning should be minimal because the UI should be discoverable enough and familiar enough (relative to other software) that you don't need to learn anything of substance to start using it at a basic level. As you get into it more, you should continue to discover things that make your life easier.

    There are many exceptions, though. For example, on most freeways speed limits are set based on safety of the rightmost lane. That's the only place they really matter, and only because of exiting and entering traffic. By the fourth lane over, there's no real harm in going faster as long as you aren't going more than about 10-15 MPH faster than the lane to your right (because doing so would mean they might not see you in time to avoid cutting you off while passing another vehicle). Yet they still enforce the same speed limit in every lane. Not to mention that they slow the speed limit down absurdly early in some cases because of rush hour making a mess of things instead of being smart and having time-of-day speed limits for those stretches.

    There's no reason in the world for 237 in Sunnyvale to be marked 55 outside of rush hour except as a speed trap. Well, maybe for a hundred feet in the westbound direction where 101 northbound enters, but even then, only because they are too cheap to make that entrance actually safe. There's similarly no reason for highway 17 in Scotts Valley to be marked 65 instead of 70 like it would be in any other state in the U.S. There's no reason for El Camino to go from 40 to 35, back to 40, then back to 35 again as you cross jurisdictional boundaries (or not). And so on.

    No, some traffic rules are designed to minimize the impact of drivers' mistakes. Others are pretty clearly designed to raise revenue, to force traffic to go slower because neighbors complain about the noise, to make it easier on the people planning the traffic lights, because the city is too cheap to put in a traffic light where one is needed, etc. Like not allowing a left turn on green in most of California merely because there are two turn lanes even if the number of cars coming from the other direction measures in the single digits per day, or not allowing a right turn on red when there's clearly no visual barrier preventing you from seeing vehicles early enough to be safe, or putting "right turn only" signs at nearly every exit to a parking lot, forcing you to go three blocks out of your way every time you try to go from Lowe's to Fry's, putting "emergency vehicle only" left turns into the parking lot instead of putting in a traffic light like they should have, etc.

    I realize that income taxes are tiered. A significant portion of the money, however, comes from taxes on business.

Combine that with the income tax tiered the opposite direction, and it likely balances out to be about the same whether you are rich or moderately poor, assuming that you are at least making enough money to get by.

    BTW, the point at which you are paying approximately the federal budged divided by the population, depending on which of the contradictory 2009 budget numbers I believe, is either $40,000 or $56,500.

  14. Re:Go to your room and no video games! on Internet Probably Couldn't Handle a Flu Pandemic · · Score: 1

    This ties into your second point. You are confusing the "epidemic cycle" timeline with the flu season. Flu season is 5 months long solely due to environmental temperatures - they are the 5 coldest months, which makes the virus easier to transmit via environmental surfaces. That's it. Since we already know that H1N1 has a higher temperature tolerance, there is no reason whatsoever to assume that it will have a 5 month "duration". Given the way it's behaved so far, it's more like 10 months - September to June.

    That environmental explanation for the flu cycle is only a partial explanation. Otherwise, flu season would be 365 days per year in places where the temperature variation is much smaller, e.g. California. Recent studies suggest that infection rate varies also based on humidity. When your sinuses are dry, you are more susceptible to infectious agents like viruses. This has actually been well understood by some of us for decades, but apparently it took until about a year ago for the scientific community to figure it out. *sigh*

    The reason H1N1 started off season is also fairly obvious. It tends to be easier to pick up than the seasonal flu because there are fewer people with immunity. More people to spread it means greater numbers of infections during the off season.

    And although environmental factors do play a role in the flu season dying down, were that the only reason, again, we would have flu season in certain western states all year 'round. We don't. Flu dies out anyway. Why? Because of herd immunity. As the number of people who have been exposed to a particular flu strain exceeds a certain threshold, there are not enough people who are susceptible to the strain to continue propagating it to others during its incubation period (after which people stay home and don't infect others very frequently).

    To determine the epidemic cycle, as you put it, we have to look at the last big H1N1 pandemic in 1918. How long did it last in any given region? About the same as normal flu---four or five months per wave. Yes, there were about three waves over a two year period, but again, that's exactly what normal flu does as it mutates.

    Also, there might be fewer waves in a modern society because rapid movement of people around the globe causes a much more rapid increase in herd immunity globally, reducing the chances of it lasting long enough to mutate sufficiently to trigger a third or fourth wave.

    Oh, and the rate of infection may be vastly overblown. If those numbers are right, then this H1N1 strain was actually affecting fewer people than the seasonal flu was during the first wave. This was, of course, out of season. The Florida data seems suspect, as it reports no seasonal flu activity while every other state reported significant seasonal flu. This might have something to do with higher rates of travel to countries with significant H1N1 rates, though.

    In the U.S., given that the second wave is not significantly mutated from the first bump, I'd expect the second wave to be maybe 1.5x or 2x the damage of a normal seasonal flu, and I'm not expecting much of a third wave at all, if any. I would expect it to die out in December or January. We'll know for sure in a year or so.

    But what if we wound up with the transmissibility of H1N1 and the CFR of H5N1?

    Then we would take appropriate action to reduce the spread of that new strain, which would not be this strain. There are a million "what if" scenarios. What if it recombined with the immunosuppression of AIDS? What if it recombined with the cancer-causing properties of HPV? Those "what if" scenarios mean we need to calmly take actions to prepare for them, not spread panic in the general public ove

    More children have died from it in the last 3 months then die all year from seasonal flu. That's 'off season'

    That's a very disingenuous statement.

    First, it is implying that the H1N1 virus is going to pick up during the flu season. There's no reason whatsoever to believe that this is the case. The flu season typically does follow certain seasonal trends, but that's not true for new strains.

    Second, the flu season normally lasts about five months, so if it dies out on schedule, it will have killed about half again more kids than the normal seasonal flu. And probably far fewer people over 30.

    WHen you consider 32 thousand die from seasonal flu in a vaccinated populaces, you begin to get the picture of how large the risk is.

    That's also disingenuous. The majority of those deaths are typically in the elderly, whereas in this strain, the elderly are showing significant immunity to H1N1. I'm not expecting a staggering death toll from this flu season. It may be elevated, but it certainly is not worthy of the amount of fear it is causing.

    The mortality rate, last I checks was 1% and rising. It's over 2% in India.

    I don't know where you're getting your numbers, and I'm not familiar with the medical situation in India, but in the U.S., the mortality rate is estimated at about 0.1%, not 1%. About one death per thousand cases. For those who aren't familiar, that's actually a little on the low side for seasonal flu. Now admittedly if we get a strong seasonal flu strain on top of that, it'll be a double dose, but for the moment, it's looking like it will probably be a relatively mild flu season, contrary to what you're saying.

    Call me when you see a flu strain with 10x the normal death rate or when it has lasted more than six months without the infection rate dropping. Until then, as far as I'm concerned, this is all just bullshit fear mongering.
