  1. Not worth the electricity needed to run them. on Obsolete Hardware Piling Up · · Score: 2

    Sure you can make a server or firewall out of pre-pentium computer. But how many people need those? (Ans: Only a few geeks would bother) And can you really do anything else with them? (Ans: No)

    In my experience, a 486 (or 68040) or below isn't worth the energy it takes to run them (especially considering today's energy situation), or the space to keep them around.

  2. Levying Environmental Cost on Obsolete Hardware Piling Up · · Score: 2

    I completely agree. In fact, I think this policy should apply to ALL products, not just computers, here in America. Perhaps the best single method to make our lifestyle less wasteful is to include the full environmental cost of cleaning up after it in the price of every item. And SHOW that price on the item, so they know just how much it is. It would encourage both producers and consumers to be more mindful in order to save money, and on top of that could actually reduce taxes by creating less cleanup jobs for the government.

    Environmental cost may be difficult to determine (and you can bet the companies will try to get away with all they can), and preventing exploitation of the system by the garbage companies (which are in at least one large city run by the mafia) might be tricky, but it beats spotty here-and-there legislation.

    These direct recycling programs for electronic appliances are a great start, and are easy to implement since you don't even have to determine cost. Expanding the system to include all electronic appliances would be simple, and could really jump-start the 3rd-party recycling industry.

  5. Bet it would break in no time on Compaq's Laptop/Desktop Concepts · · Score: 2

    It may look good, but I seriously doubt you could bring the durability up to spec. First of all, all those detachable parts (particularly the touchpad) are just begging to be lost, and since they are proprietary designs you won't be able to replace them easily.

    More importantly, the way the monitor/base part of the unit is designed looks inherently fragile. There are way too many opportunities and ways to break those two sets of hinges -

    1) If they break on their own due to heavy use. Since the hinges flex in opposite directions, it would be too easy to push them the wrong direction.
    2) If you push down on top of the screen while it's in desktop mode, you'll put way too much stress on the hinges. Of course, gravity will be doing this all the time.
    4) It looks like all it would take is a very small push near the top to knock this expensive piece of hardware over (forwards or backwards), which would be bad enough except that the three parts then have plenty of opportunity to bang against each other. And since the screen, electronics, and drives are all in that unit they could be easily damaged.

    Take it from me, broken hinges suck. They shouldn't push their luck.

  6. Farscape is way better anyways. on Voyager Eulogy · · Score: 3

    Seriously, when Star Trek was started people were overly idealistic and special effects were limited. Those two things have been bogging the franchise down ever since. And frankly, I thought DS9 was the best of the bunch, simply because it actually had a plot and characters that went somewhere, even if the station did not.

    In any case, Farscape is by far the best SF on TV yet in all ways, much better than trek, and consistently so. (The only things that came close were Alien Nation, which was very subtle and thoughtful, and Babylon 5, which was epic and diverse).

    Unfortunately I doubt if it would be easy to get the ball rolling on region elimination here in the US that easily, simply because it affects us the least. Sure, there are a lot of snipey anime fans and foreign film buffs, but they don't have much clout. Those folks also know where to find multiregion players (although I challenge you to find one current DVD-equipped laptop that can be safely modified) And as evidenced by the fact that the MPAA managed to push through a feature that really only served them (region coding) on a foreign company (Sony) whose entertainment choices weren't even protected by the regions (anyone in europe can get them if they don't mind Japanese), it will be an uphill battle.

  9. Iam Walmsley responds to my question on Light-Based Computers Using Quantum Principles · · Score: 1

    The following was in response to a question similar to my previous statement, which I received very promptly from Iam Walmsley:

    You are correct in the statement that the scalability of our experiment is no better than that of a classical system. (I don't think the UR News Release claimed otherwise, did it? If so, I'd better check with our PR people!) The point is really a different one:

    First, we have shown formally that any information processing system based on quantum interference alone (e.g. a single Rydberg atom, or a single photon) can be implemented with equal efficiency with an all-optical interferometer. The important physics here is to realize that with a quantum computer the information in the register has no reality until you read it out, and so you must account for the readout resources in determining the efficiency of the computer.

    Second, we implemented an all optical version of Bucksbaum's Rydberg atom Grover search to show that our hypothesis is correct. The resource scaling in both is slightly better than that of Grover's second search algorithm, since we do not need the inversion-about-the-mean operation he proposed. Instead, we use part of the input as a reference beam and make use of interference to do the phase-to-amplitude conversion.

    This might leave one with the impression that all interference based schemes, including those based on quantum interference alone, can never do better than a classical machine. But recent articles by D. Meyer (PRL, 2000) and E. Knill et al (Nature, 2001) show that interference without entanglement can be used to advantage over classical computers. Therefore we are now seeking to implement the algorithms they analyze optically, and to provide a measure for evaluating the resources needed for them.

    Hope this helps - rest assured we are certainly not claiming that we can do everything full-blown quantum computers can, only those that are based on single-particle interference alone.

    Parenthetically, one can look for a single marked element in a database of 2^50 items using our method quite easily, provided the database is binary encoded to begin with. But such encoding schemes are also available in classical machines. For unary encoding we are limited to 50-element databases. Perhaps this is what you meant in your second paragraph.

  11. Re:Parallel data retrieval... dear god... on Light-Based Computers Using Quantum Principles · · Score: 1

    The recombinant beam isn't compared to the original beam. When you recombine the two beams you create interference. Depending on how you set it up, the interference could be constructive or destructive for the target or background frequencies. In other words, you can rig it so that only the correct frequency will make it through, and either a)detect frequency directly to determine which value is correct or b)use a prism to spread the beam again and project it against a wide detector and see which frequencies are appearing/not appearing, and thus which is correct.

    While this is a neat trick, it isn't readily scalable and thus will be of limited use compared to a quantum computer. It is working in parallel, but with only 50 values. You could expand that number by using multiple units, but based on the capabilities quoted in the article the system can only be scaled linearly, while a quantum computer can scale exponentially.

    Now if the can/do have a way to use those 50+ bits exponentially, that's a whole other story. All of this depends on how the data is stored within the tellurium dioxide and thus how it affects the light traveling through it representing the database. Although the method indicated is a linear search the article seems to indicate that it has much more potential.

    In any case, either the article overstated things or did not report the technique correctly.

    No, the elevator would be stationary with regard to the earth's surface, not necessarily the magnetic field.

And if nothing else, fluctuations in the field would also have unpredictable effects, and likely cause all manner of stress and strain. This is another good FAQ.

  16. Uh, no on Stepping Closer To The Space Elevator · · Score: 4

    Actually, nanotubes are NOT cohesive enough. In fact in nanotube composite materials, the tubes are so smooth and so non interactive that they slip around each other and any binding matrix. So I'm afraid we'll be needing that nanotube polymerase or polymerizing reaction or nanomachine constructor. Potentially some slight modifications may need to be made - if it's twice as strong as it needs to be, maybe we could compromise that strength a little by cross-linking them. If they were somewhat longer, weaving might also be an option. Perhaps carbon nanofibers (VGCF) would be easier to produce. How would they perform?

    But there are other problems too. Nanotubes will degrade under certain high-energy conditions. Therefore they might not work so well in space. And finally, one of the forms of nanotubes is conducting. If you have an electrical conductor (the elevator wire) sweeping through a magnetic field (the earth's) you'll generate an electrical current in the conductor (high voltage, potentially useful) as well as mechanical force perpendicular to the magnetic field and the conductor (BIG problem). It wouldn't take long for that to be dragged down to earth. I'm not sure how the semiconductor form would hold up. Carbon nanofibers are very conductive too.

  20. Sorenson sucks, but 3ivx and On2's VP3 & VP4 DON'T on Can Open Source Escape The Apple Horizon? · · Score: 2

    The point about sorenson video not being licensed is tragic, but in case you didn't know, Sorenson doesn't even measure up to DivX. Despite its popularity, DivX is not a very good codec, playing it on macs is barely possible due to microsoft crippling, and there is no encoding option.

    Fortunately, besides the new Sorenson 3 codec which should be improved, and an MPEG4 codec which should become available sometime soon for QT5, there are also several 3rd party codecs coming out which have much better performance. On2's VP3 codec is already available for multiple platforms, and there VP4 codec is due soon. VP3 is an excellent codec. Better yet, the folks who made the mac DivX player are now working on their own codec called 3ivx, which so far is already more advanced than many commercial codecs. They even are working on the OpenQuicktime project, which is meant for all *nix environments, and are developing the codec for as many platforms as they can, even the PS2! Beyond that there is also Project Mayo's open source OpenDivX, FastVDO's Allstream technology, and probably dozens of others.

    Quicktime is the best multimedia file architecture which unfortunately has been hampered by slow codecs and a late start to streaming media. But don't assume sorenson is the only codec out there.
