  1. Re:Vacuum tubes...guitar amps... on Build Your Own X-Ray Machine · · Score: 1

    A lot of tube amps use 12AX7 for the pre-amp section, 12AX7s are not big tubes. Marshalls mainly use EL-34 tubes for the power sections whereas Fenders use mainly 6L6 tubes. EL-34 and 6L6 are the larger tubes, I've got a 6L6 right here and it's about 12 cm long and about 4 cm diameter.

  2. Re:Doesn't matter your wrong on OpenNaps Targeted; Gnutella "Validated" · · Score: 1

    The vast majority of those 30 million Americans are not determined Napster users. They are just people enjoying donwloading new music. If some Napster/Openap user gets in trouble with the law they will be so scared of getting in trouble themselves that they will stop using Napster.

    Right now I don't really see any real way for Napster/Openap to continue in the same way once people will atart getting arrested/fined etc.

    BTW, I started buying/discovering MORE music after Napster. Although that might not have been so if I had been into chart type music.

  3. Obvious... on Security Through Obscurity - Spam Mimic · · Score: 1

    I think these 'encoded' messages are pretty easy to recognize. From the abundant use of the phrase 'in compliance with senate bill' it shouldn't be too hard to distinguish between real spam and mimicked spam. It seems as if the encoding uses the number after the 'senate bill' part as a sort of key, so decoding a message like this shouldn't be too hard either.

  4. Re:Income? on Speeding To Become Impossible In UK? · · Score: 1

    Someone told me (I can't verify whether it's true or not...) that the fines for speeding are determined in such a way that the revenue from them is be maximized (ie. not too high so that everyone obeys the speed limit and no fines can be given and not too low to keep an acceptable safety standard).

    If they built one of these things in my car I would install a very strong transmitter that mimicks GPS signals: coordinates: somewhere in Germany on an Autobahn....

  5. Re:What do we expect? on Intellectual Property And The AIDS Crisis · · Score: 1

    Research costs money. Whether it is the government paying for it or some company. the only difference is that companies spend their own maoney on the research and try to make a profit later on. The government uses public money and doesn't have a need to make a profit.

    How much should the government spend on health care/drug research etc. ? Here in Europe it's a big debate since most health care is sort of free. Should public money be spent on keeping people tied up to machines that cost thousands of dollars to operate just to extend their life a little bit ? Should we spend thousands of dollars in public money on very expensive anti-AIDS medication jsut to keep AIDS victims alive for a little while longer ? I'm not saying we shouldn't per se but it is something to think about. The money could have been used to vaccinate little kids in Africa instead.

  6. History of privacy ? on U.S. vs. Europe on Online Privacy · · Score: 1

    Does anyone know anthing about the history of privacy ? (links please)

    It seems to me that for the greatest part of history people have been living without the 'right' to privacy. I understand that one can't compare a modern democracy to feudal/autocratic governments but I would be interested in where in history people first began thinking/worrying about privacy.

  8. Re:First question. . . on Kids and Computers · · Score: 1

    computers are just like books; a child can read comics all day or he can read something more serious.

    when I watch my little brother play computer games all day, I'm pretty shure that he doesn't learn a lot from it. Shure, some games require some intelligence, but not a whole lot (otherwise the game wouldn't sell).

    I think that computers can be a very useful tool in learning but kids can learn everything they need/want to know without them too.

  10. Re:Fan Speed on Cooling Hardware With Microfans · · Score: 1

    well, the tip velocity equals the product of the angular velocity and the radius, so to get the same tip velocity on a fan with a smaller radius you need higher angular velocity. So the original poster was right.

    smaller fans tend to be less efficient because (usually) the 'hub' diameter is relatively larger relatively to the fan diameter.

  11. Re:Why not collect that heat? on Cooling Hardware With Microfans · · Score: 1

    Huh ?

    Thermodynamics (first law) says that energy is neither created nor destroyed. So how can the universe 'lose' energy ?

    According to the second law of Thermodynamics heat will flow only in one direction when there is no external work done on it (from hot to cold obviously). Applied to the universe this means that the universe tends to 'even out' temperature differences until an equilibrium is reached.

    The Carnot corollaries to the second law state that the amount of work obtained from a system between 2 thermal reservoirs is bound by a maxiumum efficiency. This efficiency is directly related to the temprature difference

    All in all it means that if you have a certain amount of heat at a high (absolute) temperature the work that can be obtained from it is much higher than work obtained from the same amount of heat at lower temprature. After heat (witout losing it's energy) reaches a certain temprature, it becomes virtually useless because everything in it's surroundings is the same temprature

    The heat from fans is at a relatively (to the surroundings) low temprature (low quality heat) and so the potential for work being done is very small due to the low theoretical maxiumum Carnot efficiency.

  12. Re:Sneakemail on Norway Bans Spam · · Score: 1

    Here's another way of finding out how spammers got your address: When you're filling in your address on some form, capitalize some letters, the mail systems never uncapitalize them. So if you get spam with certain letters in your address capitalized you can trace it.

    I suspect that the way spammers get my address most is by computer-illiterate friends (especially girls) using my address carelessly. Filling my address in forms to send me 'fun' stuff like on-line postcards, personality-tests etc. etc.

  13. Re:Don't believe everything you read on Study Links Cell Phones and Eye Cancer · · Score: 1

    They found a correlation. That's not the same as cause-and-effect. One strong factor that many people overlook is socio-economic effects.

    I agree with this but don't you think that the people carrying out the research thought about it ? The research was done by reputable scientists, I know that doesn't mean that they don't make mistakes but it would surprise me if they overlook stuff like that.

    I'm not extremely worried about cell-phones but I've thought about what would happen if it suddenly appears that they do cause cancer after say 10-20 years of intensive use. Then there would be a huge social problem.

    Afaik almost all the research on the harmful effect of cell-phones has been done or funded by the cell-phone manufacturers themselves. I'm not saying that because of that there has to be something wrong with cell phones, I just don't like that it is that way, I would trust independent research more.

    There is such an incredible amount of money to be made/being made by cell-phone operators and manufacturers and they are so agressive in marketing their stuff that I wonder sometimes if that if there were a health hazard they would be honest about it ?

  14. Re:Is it the only thing? on Study Links Cell Phones and Eye Cancer · · Score: 2

    There's one of those antennas on the top of the 17 floor building I live in. I asked a friend of mine who is doing a Phd. on something to do with cell phones about it once and he said that right below the antenna the radiation is very small. But that's under it, I wouldn't be happy if they put an antenna like that on the same height as my appartment closeby though.

  15. some problems ? on Laser-equipped 747 · · Score: 2

    1. clouds ? - the strength of the laser will decrease as it shoots through a cloud.

    2. aiming the thing; the missile is moving very fast, the plane is moving fast and is not so stable, the missile and the plane are far away from eachother... all in all that makes it very hard to aim correctly.

    3. power of laser ? It takes a very powerful laser to destroy something, this requires some serious power generation. How hard would it be to make missiles resistant against a laser ?

    All in all I wouldn't be surprised if this plan came from a politician that is friendly with Boeing or one of the laser weapon manufacturers.

    Yeah, that's totally right. If there were no comments I wouldn't come to this site. Interesting comments/discussions make this site worth reading imo. People contributing should be valued as a main asset of this site. They share their knowledge for free and that is not to be taken lightly.

    I understand that I'm never gonna get the theoretical maximum for various reasons. The thing is that I get a fraction of my "practically possible" maximum. I think 420KBps is my about my practical maximum but when I connect to most sites (web/ftp etc.) I get speeds of around 50-70KBps, sometimes more and occasionally less. So although my connection can handle higher speeds it's other connections that slow the transfer rate down. I'm on the university fiber-optic network btw.
