    I'm sure that there are bits of code derived from BSD inside of Windows, and legally this is OK under the BSD.
    The BSD license has no copyleft provisions, it's almost a do whatever you want with it. The only important part of the BSD license is that the original source code can NEVER become NON FREE.

  3. Sony DOES own the PSN on Sony's Official Statement Regarding PS3 Hacking · · Score: 1

    So they DO have the right to ban NON-PSx consoles from the network. And a PSx running NON-SONY software isn't a PSx in their eyes, which I would agree with. HOWEVER, if I want to buy a PSx and put my own software on it for my own use (Hey, maybe I can buy a PSx cheaper than a PC with a BD drive) I should be able to do so. Just so long as I understand I no longer have a PSx system anymore and I'm not welcome on the PSN with it. Now if THAT's ALL that Sony is saying, fine. But the camels nose gets no further in the tent than that.

  4. There is another way on Two-way Radio Breakthrough To Double Wi-Fi Speeds · · Score: 2

    It's called time domain multiplexing. If you chop the transmitter on and off at a rate much faster than the data rate you can hear bits in between your chopped up transmissions. Sorta like fast break-in amateur CW where you can hear between the dots and dashes. This would require synching the two stations chop rate. Since the 'chopping' is done above the nyquist sample rate, no data is lost, and you get true full duplex speed.

  9. federal fix?? on Amazon Pulling Out of Texas Over $269 Million Tax Bill · · Score: 1

    Congress has debated how to solve the problem of interstate sales taxes. One idea would be a federal sales tax on consumption (VAT) but that would have to be a replacement for part of the federal income tax and still wouldn't solve the states issues. I think that states should NOT be allowed to collect taxes on inter-state commerce unless ALL states had the SAME rate of sales tax. But do you want a federal department to collect this for the states (you'd have to split the tax between the states where the sale was made and where the goods were delivered)?

    Sales taxes are regressive and hurt the lowest income consumers the most. Income taxes are progressive and bite the highest incomes the most.

  10. Not running out of oil, just cheap oil on Leaked Cables Reveal US Thinks Saudi Oil Reserves May Be Overstated · · Score: 3, Informative

    As others have stated it's not so much as running out of oil, but rather the cheap, easy to extract oil.
    In other parts of the world oil companies have developed technology to drill for deeper and harder to extract sources. Wells that at one time would not have been tried are today being developed. Part of this is due to the rising price of crude that has made the more expensive deeper sources worth going after. However the better technology available today also makes it less expensive than it would have been years ago. Still, there are increased risks and problems with these deeper wells (as BP has found out). If solar, wind, and other renewable energy sources can replace some dependence on oil demand will be lower and price will depend more on the cost of delivery rather than mostly on supply vs demand.

  13. I was there on Computer Industry Mourns DEC Founder Ken Olsen · · Score: 1

    I worked for DEC from 1977 till 1980. I left for warmer pastures (took a job in Florida) it would be a few more years before DEC would hit hard times. I think their biggest mistake was in not building a PC like machine. The Rainbow was just a "me too" machine, and not very well marketed. They could have boxed up their 11/70 on a chip (JAWS) into a killer machine that would have blown the AT away, and later on the VLSI VAX as well, but desktop versions of these super-minis never saw the light of day. Their upper and lower end rotted out from them leaving their networking and storage products as the only crown jewels (which Compaq purchased them for).

    The Mill was a wild place to work. With multiple buildings on a hillside interconnected by bridges you could walk out of the 3rd floor on one building and into the 2nd floor on the next. They were constantly reworking the 100 year old brick structures. One weekend they were sandblasting 100 years of grime from the walls in our building and forgot to tell the lab personal about the plans. If we had known the computers would have been shut down and wrapped in plastic to protect them. We came back on Monday to find the disk drives choked with blasting sand and brick dust with all the heads crashed! It was a good thing everything had just been backed up onto magtape!

    The millpond was referred to as an old computer graveyard. Rumor had it that someone had tossed a PDP8 and an old PDP1 out the window into the pond years ago. Maybe someday the pond will be drained and the old computers will emerge from the mucky bottom.

    Ken Olsen might have been CEO but he never drove a fancy car. He came to work in an old VW Beetle while I was working there. Several times someone got called to the security office for taking Ken's parking spot by accident!

  14. Re:Waste Heat Engine on US Team Seeks To Top Steam-Car Speed Record · · Score: 1

    You can't burn ANY fuel in a Diesel engine. If the certane rating of the fuel is too far off you will destroy the engine (try putting gasoline in a diesel and STAND BACK!). In theory you could make a piston engine that would burn any fuel, but you'd need to dynamicly adjust valve, injection, and ignition (for some fuel modes) timing and have a fuel sensor to figure it all out.

  15. Re:WTF? on Senate Panel Backs Patent Overhaul Bill · · Score: 1

    If if the patent is granted to the first to file (rather than first to invent) I would think the patent would still have to pass the "prior art" test to be valid. In other words if a company 'invents' something and then markets it but DOES NOT apply for a patent the fact that a product based on the principles that could be patented exist would make a patent for anyone else invalid. In other words, you must be first at the patent office to get a patent even if you develop the principles of the patent after someone else does. However, if the developed principles are put to use in a product before you get to the patent office then you lose because of prior art.

    IANAL, but I would think the above would apply.

  16. GPS horror stories on 'Death By GPS' Increasing In America's Wilderness · · Score: 1

    I've got a few stupid GPS stories.
    Like the time it told me to turn right and send me on a 3 mile U turn right back to the place where I turned right to cross the street I had been on.
    I could have just made a LEFT turn and saved 3 miles!

    Or the countless times the destination was on the RIGHT according to the GPS. After not finding it and back tracking, we found it ON THE LEFT!

    I wonder if anybody has sued the GPS makers for defective software that led them astray and into potential danger.

  17. Hybrid space plane? on Neal Stephenson On Rockets and Innovation · · Score: 1

    I've always wondered why to get to space you HAVE to start on earth with rockets. Air breathing engines can get us up to almost 100,000 feet in one or two stages. A large 'first stage' could use a combination of turbine engines to get up to around 50,000 feet at sub-sonic speed, then switch to scram-jets to get to hyper-sonic speed and 100K+ feet. Then a rocket powered second stage would go the rest of the way into space while the first stage glided back to earth (or flew under it's own power if there was still fuel left).

    IIRC the original plans for the space shuttle were along these lines.

  18. death ray? on 19-Year-Old Makes Homemade Solar Death Ray · · Score: 1

    With a focal length of about 3 feet it's not exactly a death ray.
    The reason this works and what the mythbusters tried did not has to do with the F ratio.
    A lens (or mirror) with an F ratio of 1 will concentrate the sun enough to make a very small spot.
    One with an F ratio of about 100 or more, not so much!

    BTW, I wonder how that shed he stored the thing in burned down? Maybe it was facing a window facing the sun about 3 feet from a wall?

  20. Re:Supermassive Black Holes? on What Exactly Is a Galaxy? · · Score: 4, Interesting

    Actually the formation of a black hole in the galaxy center may be the norm for galaxy formation. In fact, it may be a requirement to separate a true galaxy from just a cluster of stars. A true galaxy forms when a huge collection of gas condenses into groups of stars. A young galaxy forms a massive black hole at the center where the collection of gas is the densest. Then the galaxy goes through a Qusar phase where it emits two jets of energy formed by the accretion of matter into the black hole. Once all the nearby matter has been accreted into the black hole the Qusar shuts down.

  21. Re:Plug In Cars on White House Wants 1M Electric Cars By 2015 · · Score: 1

    Part of the problem here is the most electric utilities charge a lower rate for the first KW hours and a much higher rate for the last. The idea is to charge consumers for not conserving energy. As part of the program to promote electric cars the government should mandate that all power utilities would have to charge consumers the lowest rate for all KW hours used to charge electric cars, and that those KW hours do NOT count toward the consumers 'cap' before the higher rate kicks in. This might mean having to have a separate power meter for the car charger, and the government should subsidize the cost of that.

  22. enhancement or eyecandy? on 3D Cinema Doesn't Work and Never Will · · Score: 1

    I saw the Green Hornet and the 3D wasn't too dark (the glasses did darken the field somewhat but over all maybe 1/2 an F stop at most). After a while I didn't notice the 3D effect at all, most of the film didn't try to use it as eye candy and it was simply in the background though flying objects would suddenly flash into and out of view rather than be seen moving across the field of view. The only time that the 3D effect was effectively showcased was during the ending credits (cartoon like).
    The point is that if the editing doesn't try to overdo the depth enhancement the 3D effect is very subdued and you hardly notice it, but it IS there and the added depth looks real and natural. If the editing tries to showcase the 3D effect (things floating in front of your face), it's NOT a real world effect and looks it. That isn't a problem if this is the intent, a good thing at a theme park maybe but not in a drama.

    Trans-iron fusion with ITSELF is not exothermic, but trans-iron with Hydrogen?
    In small amounts this might happen in stars, but by the time a star has anything more than trace amounts of elements up to iron it has exhausted its hydrogen so any fusion of other elements with hydrogen is in the minority and doesn't contribute to the stars energy.

  25. Re:D'Addario on The Companies Who Support Censoring the Internet · · Score: 2

    So in short, you want the government to sue the pirates for you. You do have a legal avenue if fake products are brought INTO this country, but what to do if they are sold online or overseas? Some etailers such as ebay will remove fakes from their sites if presented with proof or a legal claim. Still, I hate to say this, but the burden of protecting YOUR copyrights and trademarks is up to you. You can't expect the government to do this for you. In other times a country might have considered such acts by another an act of war (such as what happened in "the mouse that roared") but the US won't go to war with China (or even block imports of similar products....though we SHOULD do that).
