    Second way to secure the system is via a firewall. Now, that is not really a preferred way, but good for cases when you cannot secure your services. XP SP2 onwards has an ok firewall. Linux has a good firewall called iptables (look for iptables HOWTO via google for information on that).

  5. Re:Why only extrapolate bad news? on Antarctic Ozone Hole Shrinks 30 Percent · · Score: 1

    I'm still waiting for people to explain how taxing carbon dioxide will actually remove it from the atmosphere


    Very easily. Carbon is removed ALL the time from the atmosphere. It is also continuously added. Currently, we (the humans, for emphasis) are adding LOTS of carbon. The rate of new carbon addition has increased significantly. The rate at which carbon has been removed from the atmosphere has also increased. The problem is that the + rate is > than the - rate. So, we need to just stop adding new carbon to the atmosphere and the levels will start to decline. Not by much, but eventually, over few decades it will get down to somewhat the same as in the mid-1900s. Then few centuries later, maybe to levels in mid-1800s (almost pre-industrial)

    Now, the answer as to how taxing CO2 removes it from the atmosphere should be self-evident. You stop adding it, the natural processes will eventually remove what is there until a new equilibrium is reached. Think rates of change not absolute volumes.

    It is the same as if gov't taxed lead paint more than non-leaded paint. The result is that lead paint will be more expensive than non-lead paint even if lead-paint is cheaper to make. This will drive lead-paint from the marketplace. Similarly with carbon technologies. If you have to pay 50% more for gas to heat your house, then maybe electrical power can be used to heat your house (eg. geothermal heat pump, 300% efficiency -- cheaper than gas without carbon tax, higher up-front cost)

    The bottom line, a carbon tax is nothing more than a customer-side subsidy towards alternatives. And it works because it is a free market economy.

    Regardless, GW Bush is right, partially. Technology is the answer and Hydrogen based economy is the future. But to help the transition, CO2 must be taxed as it is a waste product. If it is not taxed, then CO2 emitters get a free ride and everyone on the planet ends up paying the CO2 "tax" in form of changed climate. Tax the CO2 emitters and use the money to subsidize H2 technologies and other alternatives, be it the solar pipe-dream or nuclear. Think of a coal power plant and a nuclear power plant. The former gets subsidized by everyone because it does not have to deal with its waste. Imagine if nuclear power plant operators just set fire to their waste piles to get rid of them - that is what coal plants are doing. You can't even fish in many lakes anymore because of mercury contamination from coal. Heck, tuna in the *oceans* is contaminated from coal power plants. The coal industry is not paying now - we all are. It is time to level the playing field with non-carbon technologies.

    Great, the ozone layer is going down, and I can check the measurements, but don't tell me that you can't form a guess as to why, because, you can. There's always enough data to guess and always enough science to check any guess.


    Science != pseudoscience. You do not get results by guessing. You get results by reviewing the data. Because the ozone layer fluctuates so much it is NOT possible to determine if the ozone layer is repairing itself or CFCs are slowing down in degrading it. The only thing that is measured is *maximum* extend of the hole each year. Some years it is a lot less than other years. Recent years it was near maximum size or set new records. One year blip of 30% reduction doesn't even mean there is 30% more O3 (ozone). It just means that the "hole" is smaller - why? Because there is more ozone and/or wind shifted and/or ozone moved from somewhere else to antarctic and/or .... IF the holes stops setting records in next decade and starts to shirk every year (or at least is stable) then there is some news. Currently, there is just news "hey, it is not record size this year - maybe that is a good sign". Nothing more.

    Of course, news media wants their headlines.

  9. The facts about ozone holes and warmining (some :) on Antarctic Ozone Hole Shrinks 30 Percent · · Score: 1

    Sun rays create and destroy ozone at a given, constant rates. That results in some constant level of ozone in the upper atmosphere. It is a simple, differential equation here. Now, what CFCs and similar chemicals do is cause the ozone destruction rate to go up which is proportional to their concentration in the upper atmosphere. So, the result is that the constant solution of amount of ozone in the upper atmosphere will decrease.

    The ozone hole is NOT created by CFCs, it is created by upper atmosphere dynamics. Ozone gets moved around (it is in the air there). But then without the ozone holes at the poles (ozone moves people), we would have less ozone near the tropics and people would need SFP 1000. Essentially, in a state state, pre-man solution, it is very likely that there was some thinning of ozone at the poles.

    Finally, global warming. Ozone hole does not create or add to global warming. BUT, it is thought that global warming may contribute ozone depletion by affecting atmosphere dynamics.

    You forgot one thing - hydrogen does not only form water. It is also part of your DNA and other parts of cells. The dangerous part depends on where the tritium ends up, your urine or somewhere more vital. If in water, the "half-life" of tritium is about 14 days when in your body (ie. half leaves in 14 days). If in fats, well, years? more? Until tritium breaks down and screws up your fat cells?

    Finally, tritium is not really a naturally occurring element because it is unstable and because it has such a low half-life. Short half-life elements are also referred to as "hot" elements. For example, Uranium or Plutonium is not hot. Tritium and Iodine-128 are.

    In summary, tritium is not really safe for batteries. And no, Strontium is MUCH worse (Strontium-90 tends to gets accumulated in bone, like Calcium and has a nice 27 year half-life, so not good at all)

    Tritium is only good for future fusion reactions. For other applications, there are safer materials to be used. More inconvenient, yes, but safer.

    PS. I'm starting to think that Slashdot crowd treats hazardous materials like Tritium as people in 1800s treated mercury. Tritium is dangerous. It is safer to have your laptop powered by some cyanide cocktail. Beta radiation is dangerous - just because it doesn't penetrate skin doesn't mean it doesn't wrecks havoc if you ingest it - and you will if it is in any products. Alphas are even more dangerous.

True that Microsoft currently has a near-monopoly, but one may argue exactly the same in retail sector and Walmart. Therefore you pay Walmart tax?

    Regarding Dell and HP, they are getting cheaper parts because they do not pay middleman for handling or shipping. They buy huge orders from factories and these volumes make it possible for Dell or HP to get discounts. Someone like Asus when selling to end-user, they know that a percentage of the boards will NEVER sell. The consumer has to pay for these otherwise Asus has loss. So the price is higher. Of course, I still buy in parts and will continue to do so. That is the only way to have 100% control over parts, even if I pay for the parts to be put together (eg. custom order of few boxes at local distributor). That is the only way to know that I can get replacement parts at normal prices after warranty expires.
