    On Earth (may be different where you are from...:) ) in the northern hemisphere it is SUMMER (the hot time of the year) when the earth is FARTHEST from the sun in its' orbit (The orbit is elipsoidal, not round, and the Earth goes 'round and 'round the sun, mmkay?), and WINTER (that is the cold season here in the northern hemisphere) when the Earth is closest to the sun in its' orbit.

    Amazing what you don't know when you think you know what you are talking about, isn't it! I was going from memory, and my knowledge of NO2 is from the '60s and '70s - NO2 IN CARS, YOU FREAKS!

    From Molecule of the month:

    At room temperature, N2O is quite unreactive with most substances, including alkali metals, halogens, and even ozone. It is therefore widely used as a propellant in aerosol cans in place of the CFCs which can damage the ozone layer. When heated sufficiently, however, N2O decomposes exothermically to N2 and O2. If this reaction occurs in the combustion chamber of an automobile, 3 moles of gas would be produced from 2 moles, providing an extra boost to the piston, as well as liberating more heat. It also has a number of other benefits. The increased oxygen provides more efficient combustion of fuel, the nitrogen buffers the increased cylinder pressure controlling the combustion, and the latent heat of vaporisation of the N2O reduces the intake temperature. (my emphasis) Therefore N2O is occasionally injected into the fuel lines of racing cars to give more power to the engine and to give the car exceptional acceleration.


    >Ever heard of Nitrous Oxide (NO2)? Used in racing to help increase the performance of the vehicle, works by cooling the air (making it denser - more air - therefore more O2 - through the carb) before it enters the carb, does not burn or otherwise directly enhance POWER,

    You are simply replacing some of the hydrocarbons in the fuel supply with hydrogen.

    No, you are supplementing the combustable mixture in the engine. As long as you are not supplying more fuel than can be burned by the available O2, the more fuel burned completely, the better.

    At the expense of a far more complicated fuel system. Since one fuel is a liquid the other is a gas.

    Yeah, but...

    Ever heard of Nitrous Oxide (NO2)? Used in racing to help increase the performance of the vehicle, works by cooling the air (making it denser - more air - therefore more O2 - through the carb) before it enters the carb, does not burn or otherwise directly enhance POWER, just lets the fuel that is used burn more completely, more efficiently. So how about using hydrogen under pressure instead of NO2? The expanding gas would cool the incoming air as the NO2 does, but the hydrogen would ALSO burn, potentially adding to the power produced. However, also possibly using up (enough of) the O2 so the fuel DOSEN'T burn completely, which would INCREASE emissions and could REDUCE power.

    So how about injecting hydrogen AND oxygen? Other than the explosive hazard (H2 and O2 combine nicely and guickly, give the chance) and the fire hazard (hot greasy engine and pure O2 - not a safe combination!), there is the fact that this is an exothermic reaction.

  6. Re:isnt that what I said on Forty Percent of All Email is Spam · · Score: 1

    I agree it doesn't take much bandwidth to send one spam email. But it does take a chunk to send millions of spam email messages.

    Maybe it is possible to limit the metering to SMTP messages - but couldn't the spammers get around this by using a different protocal or a different port number?

    As I said, I see several problems with this possible solution. I don't think I have it figured out, I just think there has to be a technical solution for the problem.

    I agree with you that web servers should not be charged extra if the purpose is to combat spam.

    On the other hand, I can see ISPs going to metered bandwidth as a change to their business plan in an effort to increase their revenues. In that case, running a web server will cost more than my fathers sporadic email reading. But I really think you use more bandwidth and SHOULD pay more than a non-webserver-running user.

    If the ISP is buying X MegaGigaWhatsits from their upstream provider, and you are using 1/500 of that, while I am using 1/10,000, Then YOUR SHARE of the price is different than mine and your payment should also be different than mine.

    They price access based on assumed or average usage, not on actual usage - which is one reason they are putting stuff like "no servers" in their TOC. Spammers don't fit in the average user profile; they way exceed the bandwith usage an average user would use at almost any level of service.

    And that's one of the reasons why spammers pay way more than the average user for service.


    Sorry, but you lost me. Most ISPs I am aware of charge based on the speed of access, not the bandwidth used. Spammers would seem to be using fairly high speed access, but trying to max out the upstream side with as many emails as possible at the speed allowed. Therefore they are paying for the same access speed as others in their service level, but using more BANDWIDTH than their peers at that service level.

    ...but major ISPs charge by bandwidth, and my comment was about major ISPs.

    Gotcha. You are right. I am arguing that the smaller IPSs should also charge by bandwidth (which is how their upstream provider is charging them), which would shift the cost of spam back to the spammer, thus making it unprofitable to send the stuff.

    All the major ISPs are happy to look the other way whenever a high paying customer sends a little spam.

    Yep, uh'huh, and correct. I don't think your solution will work, but your analysis of the problem and the best solution for it is right on the money (pun only sorta intended ;] )

    I think the ONLY way to stop spammers is to hit them in the wallet (a swift kick in the balls only slows them down... "Candy gram for Mongo!"), and the best way to do that is to charge them for the bandwidth they use - probably through a metered access. Just as the Post Office charges by the piece (although some of the CBM - I think - is charged by the pound...), connections to the internet should be charged by the quantity of bandwith used - and outgoing should be at a way higher rate than incoming, possibly after some minimum is passed (i.e., basic access for $19.95/month, anything over X gigabytes OUTGOING charged at $10/Meg/Gig/whatever, anything over Y gigabytes INCOMING charged at $0.50/Meg/Gig/whatever). That way the bulk of the expense of the mailing would be on the spammer.

    I immediately see several problems with this solution, but it is the best I can come up with quickly.

    I hope you are trying to be funny, but I can't tell - you might be serious.

    ISPs sell bandwidth. They price access based on assumed or average usage, not on actual usage - which is one reason they are putting stuff like "no servers" in their TOC. Spammers don't fit in the average user profile; they way exceed the bandwith usage an average user would use at almost any level of service. This screws the ISP because their calculations of how many users they can service with their upstream connection is off when one of the users is sending spam.

    I don't know that they LOSE money (I would guess they do, as they would probably have to ante up anything over X (M/G/T)bytes per month upstream), but their service degrades for the number of users they have, and pissed off users are not pleasant to work with.

    If ISPs had a service level of "SPAMMER" and charged accordingly (or had metered access, where the spammers paid for the actual bandwidth they used), then possibly they could make a profit off spam. Otherwise, no, they don't profit off spam.

    As a side note, resellers are what is saving Microsoft's ass in most states on the monopoly thing. Most states say that only the people that bought directly from Microsoft can sue them if they illegally held the prices high because they were a monopoly.

    Did ANYONE buy their OS _directly_ from Microsoft? (I have not looked, does Microsoft even sell stuff directly, or do they redirect you to a reseller?)

    The companies that bought in the past are hoping to buy again in the future, so are not likely to piss off the seller (Microsoft) by instituting a lawsuit, and anyone else who bought from a third party at a price held artificially high by the monopoly has no legal recourse.

    Yes it is generally true, but why?

    If there are lots of germs/bacteria that are giving your child a sore throat, the total population will be affected by a prescribed antibiotic to varying degrees, almost none being totally resistant - and the immune system can take care of a certain quantity of the bacteria whatever its reaction to the antibiotic.

    In few cases that I can think of does a medication work with only one dose. Almost ALL antibiotic treatment regimens are for a period of time because some of the bacteria can withstand 4-5 days of antibiotic exposure, but are killed with 7-10 days of treatment. In addition, the presence of the antibiotic can interfere with the life cycle of the bacteria, allowing the immune system more time to be effective.

    Your child, for whatever reason, has a sudden increase in the number of bacteria and exhibits a sore throat. You take him/her to the doctor and get a prescription for an antibiotic. You give the first several dosed, and those bacteria most susceptible to the antibiotic are killed, as well as the immune system doing its best to deal with the infecting agent. Because of the decrease in number of bacteria, there are no more symptoms, so you stop giving the antibiotic to your child.

    The bacteria that are left, even if brought back to "normal flora" levels by the immune system, are the ones that were not killed by the levels of antibiotic in the system achieved and sustained in the aborted treatment cycle - i.e., they 'resisted' the antibiotic. Therefore, if the symptoms return, it may well be because the 'resistant' bacteria have increased in number and are much tougher to eradicate with the same antibiotic the second time - the sore throat does not respond as before, because all the susceptible bacteria were killed the first time, and these are descendents of the 'resistant' germs.
