    Actually, why not add in a way to read back the state of each of the lines going to the xor gates via say an undocumented register. Ship one batch to the manufacturer for authorization, buy it from a vendor, read the code out and you're done.

    Another solution is to wire-bond a very small microcontroller onto the pins that listens for the encryption code and writes it to EEProm memory. Microchip makes some processors that would work nicely for that. All it takes is one of those custom fabricated spychips to record the authorization code. You don't need to change any masks at all.

    The point is, memory bandwidth is NOT the problem if you're trying to transport the same data to multiple places at the same time. You broadcast it on a bus to multiple memory stores.

    Are they doing on the fly level of detail to minimize the amount of data needed for each section of the image?

    If I have this right you could have a 1 meg gaming type model rendered on an array of GPUs each with 256k of local memory (Assuming factor of four as you posted).

    Why do you say it's exaggerated with more execution units? Wouldn't each GPU execution unit have its own memory block? If 1/2 the data is a common to all the GPUs, the amount of data needed to be transferred wouldn't be that bad.

    Napalm bombs on Japan killed even more civilians than atomic weapons in Japan.
    From globalsecurity.org:

    "On 21 March 2000, the Ministry of Foreign Affairs of the Democratic People's Republic of Korea issued a memorandum detailing records of "criminal acts against humanity" committed by United States troops during the three-year Korean War (1950-1953). The DPRK report stated that the United States killed peaceful citizens by indiscriminate bombing and naval bombardment against urban and rural areas in the North. According to the DPRK, from 11 July to 20 August 1951, more than 10,000 United States planes had conducted over 250 air raids on Pyongyang, dropping as many as 4,000 bombs, killing 4,000 civilians and wounding 2,500 more. From 11 to 12 July 1952, 400 United States planes dropped more than 6,000 napalm bombs and time-bombs, killing 8,000 civilians, including women and children. "Town and country were reduced to ashes and several million peaceable inhabitants killed", the Permanent Representative of the Democratic People's Republic of Korea, Li Hyong Chol, said. According to the DPRK report, Napalm and other bombs dropped by United States war planes totaled more than 600,000 tons, which was 3.7 times the 161,425 tons dropped over Japan during the Pacific War."

    Also

    "A single firebomb dropped from an airplane at low-altitude was capable of producing damage to a 2500-yd2 area. In targeted Japanese cities, napalm bombs burned out 40% of the land area. In a Japanese residential neighborhoods with wood and paper houses, there was no way to fight the fires. On March 9 and 10, 1945, US forces dropped more than 1,500 tons of napalm bombs, all produced at Rocky Mountain Arsenal, on Tokyo. The resulting firestorm destroyed enormous sections of the city."

    See also http://www.eyewitnesstohistory.com/tokyo.htm where it states:

    "Estimates of the number killed range between 80,000 and 200,000, a higher death toll than that produced by the dropping of the Atomic Bomb on Hiroshima or Nagasaki six months later."

    It took not one but two atomic bombs to convince the Japanese to surrender, and this was AFTER the horrendous firebombing.

    Firebombing cities accomplished its purpose. From http://www.spartacus.schoolnet.co.uk/2WWfirestorm.htm :
    "A wave of terror radiated from the suffering city and spread through Germany. Appalling details of the great fire was recounted. A stream of haggard, terrified refugees flowed into the neighbouring provinces. In every large town people said: "What happened to Hamburg yesterday can happen to us tomorrow". After Hamburg in the wide circle of the political and the military command could be heard the words: "The war is lost"."

    So I ask, who are the terrorists?

    The expansionistic prisoner of war torturing invaders, the ones dropping the napalm bombs on the invaders' civilian population, the ones ordering the dropping of napalm bombs, or the ones that voted into power the people that ordered the dropping of napalm bombs?

    At some point citizens ARE responsible for the actions of their leaders. And yes, War is Hell.

  23. Re:Ray Tracing is *not* DOA on Intel Researchers Consider Ray-Tracing for Mobile Devices · · Score: 1

    None of the "enhancements" you're talking about gives ray tracing a leg up on conventional rendering. I didn't say that ray tracing would ever be faster than dirty hacks that do not accurately model the real world.

    Speed of conventional rendering, in good designs, is limited by how fast you can feed the chip geometry. YOU MUST ACCESS EVERY SINGLE PIECE OF VISIBLE GEOMETRY EVERY FRAME. There is no way to avoid it with any rendering strategy, it's just not possible. I was saying that accessing the geometry is not a bottleneck. All that is needed is more cpu and more broadcast updated ram, which (see below)

    Moore's law is working against ray tracing, not FOR it. ... which Moore's law is working absolute wonders by making available more CPU power (in this case more GPU power) and ram. I was suggesting that instead of having 1 copy of the geometry, you have N copies of the geometry, all loaded at the same time from the master copy of the geometry. Memory bandwidth ceases to become an issue, it's a matter of how much ram you can squeeze onto each GPU core.
    Broadcast is MUCH faster than either peer-to-peer or unicast.

    Or did you miss the point where you have a massively parallel GPU setup? 64 GPU cores ought to be enough for anyone :p

    - I wasn't saying that all children can be quieted all of the time. You're right, it is very nearly impossible to quiet a baby.

    Here's an idea: Create a "storm simulator" to replicate the conditions of an airplane flying in a storm: Lightning flashes, thunder booms, lurching, swaying seat, lower air pressure, and then if the child or baby continues making noise for more than 1 minute afterwards then they won't be allowed on non "family-friendly" flights. When it's not being used for testing children it can be used (with appropriate video and or gaming controls) to kill time before a flight by adults.
