  1. Re:A telling sign that a mac isn't made for hacker on The Cathedral And The Bizarre · · Score: 1

    Well the logic board wasn't that hard to tinker with. Just look at the SE series and all the hacks made to it.

    As far as shocks you should realize that anytime you open a powersupply or CRT case to be careful of stored charge.

    And suprise, suprise, its possible to hack code without worrying about the hardware. The OS has two sides, the one that deals with the hardware, and the one a programmer works with.

  2. Free mac compilers on The Cathedral And The Bizarre · · Score: 2

    You might want to take a look at http://developer.apple.com/tools/. A complete development available for free download has been available for awhile and the Metrowerks compilers were playing catch up to them until just recently.

  3. Re:Wow, an actual use for plasma physics? on Plasma Propulsion Could Cut Time To Mars in Half · · Score: 1

    Most likely they'll need to take a fission reator with them. I doubt the Pu thermal sources used in probes would provide enough power density.

    What I'm wondering is why they don't start up a fusion reaction in the plasma. While current mirror reactors, which are essentially what they are using, leak too much to hit an appreaciable fraction of the break even point they still produce energy. Have them put H-2 in the plasma and maybe some He-3. Those reactions have a low output of neutrons so most of the energy is retained in the plasma.

    My guess is that the power levels are too high for current designs. But I hope rev 2 of the engines incorporates it.

  4. Re:growing or shrinking? on Black Holes' Growth Measured · · Score: 1

    Blackholes are theorized to have a temperature of a few kelvin. But the universe has a background temperature in the 10s of kelvin. As long as the background temp is greater than the blackhole's temp they won't shrink.

  5. How about LabView on Best Way to Get Kids Started in Programming? · · Score: 1

    Take a look at LabView's G language. Its a completely GUI based language. While the compiler is $3000 there is a student version that is nearly fully functional available for ~$80. The latest version even has several internet protocols builtin. Plus it has an excellent math library and data analysis package that would do very well for any science classes they take.

  6. Wrong on Add-On Shows DVD As It Should Be · · Score: 1
    Bob Auger of Electric Switch, a DVD production company, says: "This is the first time DVD is being seen as it is meant to be seen."

    A PowerMac G4 with the Apple Cinema Display is completely digital from the DVD drive to the display. In fact they had a demo with A Bugs Life at the Cinema Display's release.

  7. Re:Who will own the 3 seperate companies ? on Will The DOJ Split Microsoft In Three? · · Score: 1

    Minor stake holders will just have their shares divided into shares for each company. Major stake holders like Gates will be forced out of all but one company. Of course the means of doing so without collapsing the price is questionable. The way I see it is that the minor holders will get a good return but Gates and company will lose quite a bit since the stock will likely be depressed in value when he has to sell.

  8. Re:Duopoly on Government Gives Microsoft Offer Thumbs Down · · Score: 1

    A specific mention in the breakup agreement that prevents coventures/cooperation of any kind. I would like to see it enforced with criminal punishments for the individual violators but more likely they'll put a hefty price tag on any cooperation.

  9. Re:Just in time for mac OS X... on Rumors Of MP PowerMac G4 Flying! · · Score: 1

    Depends on what you are doing. MP on linux is pretty much useless when you only have one hefty process. The MP support in the current MacOS is really based on the pthread model. Even on linux you have to specifically code for true parallel processing in the same task.

  10. Dragon's Egg on Physicists Find More Precise Gravity Number · · Score: 2

    There's already been a very good book written on this called the Dragon's Egg by Robert Forward. A manned mission is sent to a drifting neutron star that passes near the solar system. The natives evolve from 'plants' to an intelligent species in the time the mission takes to reach the star and they go from 'stone age' sun worshipers to space travelers more advanced then us in a matter of days. Communication is established with a gamma ray based mapping device that some of the natives can see.

  11. "Oh Shit" on Apple Announces Darwin 1.0 · · Score: 1

    Actually this reaction caused only two things, the rest are secondary. First Carbon was invented. For those who don't know Carbon is a library that sits on top of Darwin to implement nearly all the recent MacOS API's - very similar to WINE. The second action was a delay in release due to creating/adding/debugging Carbon. Everything else; new mach kernel, new display engine, etc are incremental improvements that would have occurred anyways.

    The primary reason for the new display engine was cost. With DisplayPS they were paying a license fee to Adobe for every copy of OS X. As a result they created the new display system and blazed the trail into vector based displays.

  12. Re:RFC: Gravity and Magnetism are related. on Anti-Gravity Research Confirmed · · Score: 1

    There are 4 forces in the current universe that we know about:

    1. ElectroMagnetic
    2. Gravitational
    3. Nuclear-weak
    4. Nuclear-strong

    So far the weak nuclear and Electromagnetic can be mathematically united and the strong nuclear force appears possible with a lot more work. Gravity is still the lone man out.

    I think part of the reason is that we don't have any extreme fields to work with to see how the force behaves. The suns field is the best we have to work with now. Unfortunately where it gets really interesting in its space time warping the radiation fields get really intense ;-). Even with these obstacles there was a very interesting article in Science a few months ago about gravitational harmonics in the plaentary orbits.

  13. Re:Our brains... on First 7-qubit Quantum Computer Developed · · Score: 1

    Actually I read an article a while ago that implied there was a very high probability that the molecular ion channels in the axons can have quantum resonances. Proving that any such resonance has an effect on the neruo transmitters would be a huge breakthrough. Who knows, perhaps our brains are already quantum computers.

  14. Good Science Fiction doesn't break the rules on Review: "Mission To Mars" · · Score: 2

    You're crossing the border into the Fantasy genre when you break the rules of known science. Science Fiction has always been an attempt to predict future technology in the present reference frame and optionaly social norms.

    The only time you're really allowed to break a currently known physical law is when its central to the plot. I think that was one reason that Star Trek had such a stronger impact in its original version. The created tech had more room to be plausable. Now that science has caught up so much, the Trek franchise is caught in the dilema of abandoning its previous 'tech' or start breaking rules that current science is beginning to establish.

    Again, transgressions against science in science fiction are ONLY okay if its central to the theme. This just really irks me as a scientist myself because people don't seem to realize that unlike other laws the laws of physics can't be broken.

    The best science fiction manages to blend plausable science and its influence on social structures. Of course I may be impartial on this since Asimov is my favorite SF author and that was one of his central themes.

  15. Re:*I* can find primes fast! on SSH v. SRP · · Score: 1

    But who cares about primes 2^32. Especially for cryptography purposes. Write a program that will find all the 1024 bit primes quickly and we'll talk.

  16. Re:What about IEEE 1394 on Western Digital Pulling Out Of SCSI HD Business · · Score: 1

    Yup, Fantom, FirePower, LaCie, ProMax, and others all have current products.

  17. What about IEEE 1394 on Western Digital Pulling Out Of SCSI HD Business · · Score: 1

    Does anyone know if the current 1394 drives that are essentially IDE with a bridge to 1394 have the same CPU time consumming properties of IDE?

    I really don't see what the big fuss is about SCSI starting to fade out when there is a superior standard in place. What really needs to happen is for true IEEE 1394 based drives to come out. The IDE bridge chips are starting to become the speed bottleneck, giving the bad impression that the 1394 drives can't perform.

  18. Never read Contact? on Distributed.net CSC Success · · Score: 1

    I take it that you've never read Contact. While the movie only had a simple message for her to bring back and a few hours of static on her video recorder there was a much better message in the book.

    --Spoiler for the book--

    Essentially the beings at the end of the wormhole express ride had discovered the true Bible, aka word of the creator. While the scientists were there visiting the core the beings pointed them to where the works were recorded, inside transcendental numbers.

    When they got back she set her supercomputers to use the SETI pattern recognition routines on Pi. After a few billion digits or so the computers found something.

  19. Message from the Watchdogs on Full Lunar Eclipse for North America · · Score: 3

    Dear God:

    This is to notify you that your program entitled 'full-moon screen saver' has a rather severe cosmetic Y2K bug in it. As a result, on January 20'th of your year 2000, the full moon will experience color and brightness difficulties that significantly deviate from the published standard. Our analysts believe there is even a chance it may turn red, a widely touted feature of your 'shutdown/halt' program, possibly causing confusion among your users.

    We strongly encourage you to correct this problem at your earliest convenience.

  20. Re:Health concerns? on New Body Scanners Installed In Airports · · Score: 1

    They've been used in CA prisons and the dose is from 5-10 micro-rem for each side. Since the dose is so low it is actually hard to measure. For comparison, just from the background radon levels we get >500 micro-rem a day (http://www.umich.edu/~radinfo/introduction/radrus .html)so I wouldn't worry about walking through this type of scan at all, at least for radiologocal reasons.

  21. Its Java on top of quicktime, not QT on Java on Apple Posts Darwin / Open Source News · · Score: 1

    All the 'plugin' gives is the ability for java apps to make calls to quicktime, it doesn't try to implement quicktime on top of java. You still need a native quicktime library available for the java-quicktime calls to work.

    So why go to Mars then. Set up a base on the moon, get some then jump to the asteroid belt. I seem to recall that Mars was rather poor in the minerals.

  23. Clarification on Five Possible Life-Bearing Planets Found · · Score: 1

    It wasn't light reflected off the planet but a huge coincidence in orbits that put the planet directly between earth and its star. The star dimmed noticably and the spectra changed as the starlight passed through the planets atmosphere.

    The best part is that it looks to be a highly reproducable phenomenom so a lot of different telescopes can back up the original observation.

  24. The regulation has gone missing on Alien Contact Illegal in US · · Score: 2

    I just checked out the Code of Federal regulations and that subsection they specify as containing this law doesn't exist. Take a look here for Title 14. It lists all the regs governing NASA.

  25. Apache Plugin needed? on Teen Sued for /Linking/ to MP3s · · Score: 1

    This sounds like it could easily be fixed. Create a plugin that checks the referring page from the URL request. If its valid/local let the download occur.

    Essentially just leaving things open like this is equivalent to leaving a pile of money on the sidewalk in front of the shop and complaining when people steal it. A good lawyer could argue that there was the impression that the material was free for all use unless specifically marked otherwise. Its toeing the line but possible, especially when there is a way to restrict the downloads transparently.
