  1. Re:What is its dynamic range? on Seitz's 160 Megapixel Digital Camera · · Score: 1
    Really? You mean it is possible to take an 8MP image and squeeze it down to 2MP and get 4 times better dynamic range? How? Let us take a saturated pixel in the CCD. And its saturated neighbour. One might have been twice over the saturation threshold and the other four times over. They both register saturation thresholds. By combining these two pixels, how can we get more detail in the washed out portions of the image?

    So you throttle down your aperture to make sure the highest intensity recorded is just the saturation threshold. At that point so little light hits the CCD that the "dark" area pixels are all below sensitivity threshold, or they all register 0 photons. Again combining them is not going to improve the dynamic range.

  2. My guess on Seitz's 160 Megapixel Digital Camera · · Score: 1

    The article is quite skimpy on the technology. By the size of the camera I am guessing all they have done is to split the image optically into some 16 or 20 pieces and are using some 18 or 21 CCD image sensors to capture the image. They read these chips in parallel and load it into an internal buffer. The dynamic range if each CCD sensor is exactly same as what you could get in 5 Megapixel camera.

  3. What is its dynamic range? on Seitz's 160 Megapixel Digital Camera · · Score: 4, Interesting

    What is the big point in churning up the pixel count, if the dynamic range is the same old 1.0e03? Human retina has a dynamic range 1.0e06, three orders of magnitude better. And it has about 2.7 million rod cells and cone cells. One can create amazing speakers with absolutely perfect sound fidelity at 150 KHz, but human ear cant hear it. There could be some applications not involving human hearing/cdplayers/boom boxes. But at that point it is not really a "speaker". Same way at 160e06 pixels or 720e06 pixels it is not a "digital camera". It is some exotic machine with really pathetic dynamic range and huge number of pixels.

  5. MS can do it as fast as these little twerps on Zero-Day Team Launches with Emergency IE Patch · · Score: 2, Insightful
    Of course MSFT can find the bug as fast or faster than these thirdparty do gooders. And if the aim is to stop the exploit they can do that too as fast. Did you notice how fast they fixed the WMP DRM breaking exploit? They can do these things if they want to. Infact they can even make IE as exploit proof as FF if they want to.

    But they dont want to. There are thousands and thousands of sites that have hacked up code to step around the bugs in IE. They all will break if they lost back ward compatibility to these harebrained hacks that depend on the bugs in IE. MSFT considers it a big loss of face if more sites work in FF than in IE. If they fix all their bugs and holes in IE, more sites will work in Opera and FF than in IE. That is a big no no. That is why they tread cautiously making sure they fix the hole, just that hole, and nothing but that hole, and fix it just enough, so that most of the other hacks can continue to work. That is why they are so slow in responding. That is why the fix has to be fixed and fixed again.

  7. Dont p*** off Joe Sixpack on Microsoft DRM To Get Even Tighter · · Score: 4, Insightful
    OK, Joe Sixpack does not know much. Blindly uses the default programs. IE, WMP whatever. Cant even tell where OS ends and applications begin. And MSFT takes him for a ride and locks his content to one PC and does what most monopolies do when they think their control will last forever.

    Isn't that normal? Isn't that what will eventually provide a market correction? Eventually Joe is going to find that 500$ worth of music he has bought over the last two years is locked into a dying PC or a stolen Zune and he has to pay all over again to get his music back. Then his friend Smartli Nuxuser tells him why he would never have that predicament at the watercooler. Happens repeatedly. Gets retold repeatedly. Joe gets mad

    When Joe Sixpacks gets mad, he really gets mad. He sues left right and center. Start class action lawsuits. When CA builds million miles of highways and sues the car makers fo CO2 emissions, why cant Joe Sixpack sue MSFT? It can write all the EULA it wants, but when you get millions of Joe Sixpacks mad, all bets are off.

  9. Re:Scaling down heat engines? on Engine On a Chip May Beat the Battery · · Score: 1
    I mentioned the problem of scaling down steam engines just as an example. Gas turbines are, infact, more difficult to scale down. Once the science got the physics of steamengines right, they have scaled down steam engines to extremely small sizes. You might have seen small steam locomotives just a few feet long. There is a toy maker in Pittsburgh who churns out real working miniature steam locomotives.

    If gas turbines are easy to scale down you should see gas turbines at smaller horse powers. Gas turbines have a higher efficiency than diesel and gasoline engines. (40% vs 30%) and have simpler maintenance due to lack of vibration. IC engines hurl out high mass pistons and whip them back around the crank shaft. Gas turbines run smoothly without vibrations because they are inherantly symmetric. But you dont see gas turbines at smaller than 1000 HP. Even in marine applications, steam turbines dominate the high end and diesels dominate the low end. Only on a narrow range of power ratings gas turbines have an edge, even in marine applications. So many of the back-up diesel generators could be replaced by gas turbines if they could be scaled down. They dont.

  10. The 80-20 Rule on Engine On a Chip May Beat the Battery · · Score: 1
    You will be surprised at the range of issues where the 80-20 rule applies. 80% of all wealth in a society is in the hands of 20% of the population. 80% of the crimes are committed by 20% of the criminals. 80% of the inventions are made by 20% of the scientists. Computer executables spend 80% of the CPU time in 20% of the code. 20% of the hurricanes do 80% of the all damage done by hurricanes. 20% of the programmers cause 80% of the bugs.

    Infact 80-20 split is the lower end of the scale. Most of the time it is skewed even more highly. For executables it is likely to be 95-5 split. I once profiled a complex (as in complex number with real and imaginary parts) matrix solver that spent 90% of the time in complex::operator*() and complex::operator+(). BTW just by correcting the rookie mistake of return result; to return &res; speeded up the code by 20%.

    The last 20% of any project takes 80% of the time. Whether it is hardware of software, getting all components to work in isolation qualifies as 20% completion of the total project. BTW, I dont work on web projects with PHP/java/javascript. I work in Computational Electro Magnetics. Mostly C++, non-graphical, non-event driven hard core simulation of physics.

  11. Scaling down heat engines? on Engine On a Chip May Beat the Battery · · Score: 4, Interesting
    When steam engines were invented and developed in England by Newcomen the science of thermodynamics was lagging the technology. The steam engines work obviously but they could not get scaled down versions of the steam engines to work at all in the lab. Mainly because real engines were made with cast iron but the lab models were made with brass and it conducted away the heat away too quickly. At this time a man named James Watt, an instrumentmaker by profession did lots of work on the lab models and made an improved steam engine by mainly making the steam condense outside the cylinder. Also he invented the Watts Governor to regulate the speed of the machine. The moral of the story is that, heat engines dont scale down as easily as electronics.

    Fluids in general behave much more differently in microscopic quantities than in large bulk quantities. I expect to be lugging large batteries for some time to come.

    Yes there was time more people knew WordStar commands than the entire population of Pakistan, but when WordPerfect out did WordStar, it did it with a better product. When Lotus outdid Visicalc it did it with a better product.

    When Word out did WordPerfect, it was through bundling it with OS, getting steep discounts on the price of OS to the OEM installers if they DONT install or sell WordPerfectb by throttling the revenue stream of WordPerfect by leveraging MSFT's monopoly in the OS space. That is how it won. And what happens after it wins? Just look at IE after it won the war with Netscape. Just look at the price increase in MsOffice while the hardware prices dropped by orders of magnitude. Starting from a pale imitation of a competing software is not the bad part. It is killing a superior product with underhand tactics that hurts us users. All of us.
