  1. Both? on Wiring A New House? · · Score: 2

    Fiber breaks fairly easily - its a big problem. You might put it in there, and have it work fine for a long time, and then something breaks SOMEWHERE and you don't know where, but you do know that you've lost your connection. Copper is far more durable. If you put in the fiber and the CAT5, you could use the cable as a backup.

    Having said that, 100Mb per second is pretty fast for games, X-clients/servers and harddrive reads and writes, unless you really want all the computers to act like one computer. Maybe that's what you want. I don't really care myself. If I want to work on another computer, I walk over to the other one and sit down. So even in the future, I'll probably always be happy with CAT5.

  2. How fuel cells work on Fuel-Cell Backup Power Under Your Desk · · Score: 3, Informative

    Hydrogen, being the lightest element, doesn't go liquid until close to absolute zero at standard pressure. Even if you make the pressure dangerously high, the refrigeration will still keep it from being worth it to force it into the liquid state. An oxygen molecule is 16 times the size, but it still takes some work to make liquid oxygen, and the pressure would once again be dangerous.

    How do they not take up too much space, as you said? Fuel cells are extremely efficient because rather than producing pneumatic energy from combustion which is then converted to electrical energy, they essentially make a battery out of them that fuses hydrogen and oxygen to produce electricity. But they still don't usually store hydrogen or oxygen.

    Fuel cells usually have a liquid forms - these are produced by dissolving or chemically combining hydrogen with less electropositive and negative elements (making an acid and a base), and then removing the hydrogen from this right before it is needed. Typically, the hydrogen is removed from an alcohol. Oxygen is just taken straight out of the air.

    Here is a good summary of fuel cells, if you want to know more.

  4. Some more insight on Earthlink Buys OmniSky · · Score: 2

    Apparently not a lot of history buffs (and by that I mean people who remember taking it at all) among the moderators, judging by the fact that my previous post has been labeled an offtopic troll. The Standard Oil Company, led by the Rockefellers, was pictured exactly as this because they kept buying up companies that had roughly anything to do with oil to become a verticle AND horizontal monopoly. In fact, it was known by its opposition as "The Octopus."

    This seems to be happening again...and again...and again in the software industry. Different kinds of software are being bought, and big companies are growing both vertically and horizontally. The example shown of Earthlink IS such an example.

  6. Re:The main problem on Building a Cheap Oscilloscope Using Your PC? · · Score: 1

    Sorry, I made a mistake. Soundcards sampling capabilities makes them only capable of detecting frequencies above and below the range of human hearing. And actually, most soundcards can do variable sampling rates, but not between samples.

    I say this not because they can sample better; for the purpose of having an oscilliscope an oscilliscope is better. But an oscilliscope can't do all the things to a signal that a PC can do. This is the beauty of the acquisition card.

  7. The main problem on Building a Cheap Oscilloscope Using Your PC? · · Score: 2

    An oscilliscope just samples input voltages and displays their amplitude. That's REAL tough computations (NOT!). And a frequency analyzer (often used for a similar purpose) just takes a fourier transform of the signal (this is a mere O(n log(n)) complexity problem). The software is trivial!

    The main problem is the sampling rate of the hardware. Soundcards are made with a sampling rate that is only slightly above and below the range of human hearing, which means that for many circuit frequencies, they are unacceptable. If this will work for you, the coding is rather simple since its the well known I/O operations that have been used in PCs forever. Just learn a little bit about SOME sound API and output the wave output from the soundcard in real time. I'm sure others have done this before, too. Its a 4 hour job.

    If you need better accuracy than that, you need to buy a data acquisition card, but it will cost you a pretty penny for them. Here is a list of some of these cards.

    There are some up sides of having a card such as this that can capture high quantities of data, the biggest being that if you know C, and you get specs on ANY kind of input signal, you can often write a driver for it - NTSC signals, radio signals, digital video signals...pretty much anything.

    If you really want to do this quickly, get something like the matlab and use the data acquisition toolbox.

    In my opinion, a data acquisition device on the computer beats the pants off of an oscilliscope any day.

    That's exactly what I use Windows 95 for.

    I put a copy on my Dad's old P-133 laptop so that he could do word processing for his job (he's not quite Linux ready, and neither is the laptop). It runs. And so do the programs I installed on it.

    I know what you might be thinking: "that's old stuff, and old stuff is as supported as it gets on 95." Well...
    there are still a lot of products out there that use simple Pentium chips and small memories that keep coming out that could use a good Windows API every now and then.

    So what is our recourse for "Lite" systems, if not older versions of the software if Windows is required?

    30 years ago, science fiction was kid's stuff - only children wanted to watch it, only children liked it, etc.

    30 years have passed, and the children have grown up. Now Sci-fi is a complex medium intended for the use of adults - it grew up with its fans.

    15 years ago video games started getting to be more than just 'Pong,' and the children started to play them. Now games are complex, and getting more so. Today, games are still for the young - but not just for kids.

    A mere 10 years ago the net started to become a popular means of [everything the wired article talks about]. It has powerfully transformed the world BEFORE a generation has come to power. That is truly amazing, but you can't expect all of the changes that are on the way to happen overnight.

    In 20 years, after the internet has had as much time as Sci-Fi to become commonplace, we will be an internet generation. Then all the people who are using this as their media outlet will have it, and just like the stock market, it will become a chaotic tyranny of the majority's decisions swayed by the charisma of those who write well.

  13. Re:Fate of the Universe . . . on "Dark Matter" Observed · · Score: 1

    No its not. At least not under the current model. Its been proven that since gravity is not strong enough to keep the universe from expanding NOW its not going to be strong enough to keep it expanding later due to the conservation of mass (since there is roughly the same amount of mass in the universe always, there is a roughly a constant amount of gravitons, while the necessary force to stop the universe from moving keeps increasing).

    Of course, with our microscopic view our theories don't hold a lot of water. If we could visit a couple million planets and get viewpoints from all of those, I expect that a lot of our theories about the Universe would change.

    Perhaps the Universe isn't even expanding now, and space is simply a closed hyperparaboloid.

    It seems that perhaps the moderator who posted my comment as "offtopic" has a little difficulty with the whole "reading" thing. Those examples that I gave were to illustrate the point, not to just spout stuff.

    Let me explain my message. I gave some examples of reviews that weren't worth making, specifically picking things that don't have very many features. For example, a shoe, for the most part, is a shoe. There isn't a lot to say about it - its only features are comfort, durability and style. Also, there are LOTS of shoes.

    So...my point was that when the only features are harddrive size, PC interface, and cost, what's the point of making a review? Its about the same as reviewing shoes, or hamburgers, or laptops brands (not actually the laptops themselves).

    McDonalds makes hamburgers. They taste good, but the ones from Steak & Shake taste better. However, they are more expensive.

  20. EXTREMELY Useful on Waste Heat to Electricity? · · Score: 3, Informative

    When dealing with vehicles of any kind, the primary problem is that the energy source has to be portable. Therefore, you need a source with a high energy density. In other words, something that you can get a lot of energy from while it takes a small amount of space. Even more importantly, you want the energy in a form that you're going to use it in, or as close as possible to such a form, because conversion of energy causes a loss of energy.

    To date, combustion based systems have the highest energy density of any portable energy source (barring fission reactions). Therefore, there will always be a use for it.

    Perhaps automobiles won't necessarily need them - we can afford to carry additional weight - the fuel/weight ratio for automobiles is evidence of this - you can carry a LOT with a small amount of fuel for a car - and you can then drive for a long time.

    But what about flying vehicles? Fuel/weight ratio is EXTREMELY important. The more efficiency that we can get the better. The best part about this is that it might remove the need for an alternator, which drains the power and adds weight to any flying device (which is significant for the small vehicles, such as the automonous surveyor helicopters used by the U.S. military). Improvements in fuel usage can mean a big deal for the aircraft industry.

    Of course that's not the only industry that will benefit. Heat-differential technology is used as a power source for some areas...have you heard of geothermal and solar power plants? Know how those work? What if they could double their output? That would be significant.

    This, like many innovations, is just another step. Handsprings are slightly more modular than other forms of PDAs, while still having the minimal power consumption associated with palm pilots.

    Many people, including myself, believe that the next frontier of technology is small, portable devices that communicate with each other wirelessly, though each device has a specialized function.

    In order to make that happen, we need to start with devices such as handhelds - which CAN be easily specialized through software, and which have readily available wireless capability.

    Its true that its "Just another handheld," similar to all of the other handhelds, but its more functional. Its not like another model car, which is exactly like the previous model, except that its "new and improved" (i.e. new and the current fashion); this is another piece of the puzzle.

    And IT DOES MATTER that its slightly more functional. The advent of the 386 chipset allowed a whole new class of problems to be solvable that where previously too slow to do research - I know that this is the case for my field, which is computer vision. As time progresses, even more problems are being researched.

    I'm looking forward to using technology such as this -perhaps even this model - in the near future (when it becomes pretty inexpensive - perhaps two or three years from now) as a module for home automation - it would be just about perfect for the purpose.
