  1. Re:What balance? on Greenspan Examines the Economics of IP · · Score: 2, Insightful

    What balance? Doesn't rewarding innovators with a patent naturally inhibit follow-on innovators?

    The balance Greenspan is speaking about is "the incentive to innovate" vs. "Prohibition of innovation". Things must be protected to provide incentive, but not overly protected to prohibit follow-on innovation.

    AIDS victims often advocate that AIDS drugs should be free or have their patents nationalized or invalidated so that all of those who suffer from AIDS could afford medication. The big problem with this is that if the profit motive is remove from creating AIDS drugs, companies won't risk hundreds of millions required to develop the drugs. If private companies don't pursue these drugs, AIDS victims will have to rely on new medications being created by government grant research only. This is often much slower that having several private companies competing to develop the best drug.

    The balance is adequately rewarding each innovation so that people remain motivated, yet not protecting IP so much so that it effectively locks all future innovation in that area.

  2. Age increases chance of genetic change. on More Evidence of Increase in Profound Autism · · Score: 1

    As a person ages, the likelihood of RNA creating genetic misspelling in DNA increases. Locations where DNA is being replicated often is the most likely area for RNA misspellings during DNA production. This means that sperm you produce today is less like you than sperm you produced when you were 15. As you age and misspellings compound, useful genes may be modified (vs. junk DNA which is more like a personal serial number than something that changes your existence).

    These "misspellings" of useful DNA aren't bad or good, but simply different. The differences could give your child a genetic advantage just as easily as a genetic disadvantage. If Autism is, in fact, genetically related, the misspelling could create the gene recipe for Autism in your offspring, or it could create a gene recipe that is further away from Autism than you currently are.

  3. Re:Locked in by a blackout? on Reconfigurable, Modular Dream Home · · Score: 3, Informative

    As someone who currently lives in a house with electric locks on all doors it still works fine in a california blackout. Here are our basic design criteria:

    * All doors that don't need to open in an emergency are fail secure. This means that with extended power loss or critical failure the doors stay locked.

    * All doors that must allow egress during an emergency or critical failure should release bolts under failure (fail safe) and allow the door strike to function like a normal door (latch the unlatched strike). This unbolts the door, but also causes the standard positive latch to fall into the strike. This provides a secure door with manual egress

    * garage door won't function anyway.

    We have batteries that keep each door alive for about 2 hours. The front door has enough battery for about 6hrs. After that entry becomes a bit more complicated. After critical failure or extended blackout, entry requires a physical key in the one door that has a keyed knob. That door's bolts are fail safe so it should be unbolted, but key-latched if the system fails.

    Normal entry is via proximity access control with a standard HID card.

  4. NEC 50MP2 can't support Native rate over DVI! on High Resolution DVI Support for Plasma Displays? · · Score: 1

    I'm late to this discussion, but hopefully this will get modded up before someone spends $9K for this display. Nobody has pointed out the most critical bit. The NEC 50MP2 will not support native rate over DVI. There is no way to get a 1:1 pixel mapping via DVI on the NEC 50MP2!

    I had a similar application and decided to go with the Pioneer 503CMX because of the native rate support. The 503CMX is one of the only 50" displays that won't mess with the native rate image and directly display each pixel.

    NEC specs say they will support the native resolution, but they actually use the internal scaler before the image is displayed. This prevents 1366x768 images from being directly mapped to pixels. Instead you get something "close" to what you want.

    There is very long threads on the difficulty of getting most Plasmas to do native rate over DVI at AVS Forum.

    Search for "Native rate dvi nec 50mp2" at http://www.avsforum.com for all the threads on this problem with this display.

  5. Because fuel processors cost $$$ and space. on Fuel-Cell Backup Power Under Your Desk · · Score: 1

    A fuel processor is needed to strip the hydrogen from propane or natural gas. These fuel processors are expensive and take additional floor space.

    Propane and natural gas are much more functional solution for a data center fuel cells, where they can be located in a fixed place and make use of city natural gas lines or large propane storage tanks.

    This particular fuel cell seems to target a different market. The under desk, or portable power generation market probably can't have the space or weight required to include a fuel processor and additional BBQ stryle propane tank.

    There are a couple on Ebay. You can always buy the replacement there.

  7. Build a 1 TeraOp machine for $100! on A $1000 Supercomputer? · · Score: 1

    A quick look at an old Xilinx databook shows that you can build 1,600 4-bit adders in an old (1997) XC4085XL. The switching characteristics show a 1.6ns delay for each adder.

    If you don't include innerconnect delay, you can build your own 1 TegaOp supercomputer for about $100.

    (1/1.6e^-9 * 1600 adders)

    Xilinx has come a long way since 1997. They now claim to have 1 Million gate FPGAs, that run quite faster than the old XC4085XL-09.

    But if you really want to really go for the TeraOps record, I'd suggest Xilinx's latest Virtex parts, and a benchmark doing 2-bit binary NAND operations.

    It may take some additional work to get such a chip to emulate WinNT, but think of the press coverage your benchmark will get.

  9. We work with you to define the goals on NT faster than Linux in tests · · Score: 2

    "We work with you to define the goals you want to achieve via testing."

    As their main web page states, they define the goals before they test. The only goal was to say NT runs faster than Linux. I've never heard of this company before. I now know why.
