  1. somehow I feel like I'm making fire with flint when cutting cat5 cables, where shouldn't current networking students be learning fiber cables? I'm wondering what possible transmissions speeds could be achieve using spdif cables if such technolgy existed for local networks. The scenario is having 10-20 workstations connect directly to each other using fiber instead of ethernet but the NIC having 10-20 ports for a direct connection to each machine in a workgroup. If it more efficient for an OS to control 20 connections locally (room) or communicate with a DCE device (in the same lab)?
  2. I'm trying to find out if like metal based conductors, silicon based polymers warm up when a current is passed through them. If they produce heat alone or if they release any amount of light. Could silicon or a silicon based polymer be used as a filament.
  3. As per Ryan's post about a lightning propulsion system.. (funny because my name is Ryan too :Glasses: ) I have a question, general, about the concept of an Ion Cannon. While reading the Ashes of Worlds (not lightning weapon as described, they many 'directed energy beam'), the techno garble finally got to me. Lightning from space is a bit beyond silly. At least with my limited understanding of the associated physics. Any large arc of lightning needs a source end and a target end and a channel to pass through. Lightning doesn't occur without a tracer coming up from the ground. Once there's
  4. Well put. You have to think for yourself, or be trained to think for yourself. A current problem does require acknowledging existing wisdom, but the most effective tactic is thinking about all the current aspects of a problem and not just trying to apply some blanket judgment/solution which might not fit this current problem. Having said that isn't it more efficient to try to get a very large group of people behind an established method or solution to a problem, than to try to hash out a unique solution, explain it and sell it in a timely efficient manner?
  5. I like to think that because a person, and then group of people don't NEED anything beyond food and a bare minimum of resources, of course you're going to end up with a spectrum of higher level rules to govern bigger groups of people. Cultures. How they interact is just based on what needs they might have, or think they have within those higher level constructs. A society or nation has needs.. sure. They just don't always apply to smaller groups of people and so remain virtual needs that have to be met by an effort of many people working towards it. The way I see it intellectual sophist
  6. By that time will there be a humanity as such. First you have to expect that humanity can prosper under one banner. Otherwise we'd have to see colonies with samplings of established human cultures which would be prey to large empirialistic states. As we can see economics can work as a focal point to international, interplanetary, and even eventually intersolar trade. But the core of the matter is without trade there is nothing to tie to separate cultures. I have a hard time trying to think of any two cultures that don't trade, one is visibly better off than the other, but they still ge
  7. I was just reading my back posts and reaquainting myself with this community.. I hit an old question about which console would lead this current console generation. I'd pegged Xbox 360 But as time wears on and so does the economy dragging its heels.. comes an update to the Xbox platform in the form of Natal. It's, as far as I can tell, a motion controller and voice recognition system with brains in the device so as to offload the processing of visual and audio recognition. Though there was mention of it having further capabilities that sould like sonar or doppler. Of course not much
  8. If it's a CRT TV (Cathode Ray Tube) it (TV or Signal) might be out of sync. It needs to draw many lines of the picture per second at a certain rate. If the rate of the frames it's drawing and its native drawing rate are out of sync you'll see it as lines in the image (or the image moving vertically up or down the screen). You should have a tuning control in the back on older models of TVs. Otherwise at the moment I couldn't think of anything that would cause it on LCD or any other type of digital TV. Again, if it's a digital TV and Signal, call your provider and explain the entire p
  9. We've all seen them, they are cute... but not wide spread for public consumption. But, what would be immediate limitations to a tiny wvga OLED transparent eyepiece as an attachment to existing bluetooth (3.0) earpieces? I was told the new 4G iPhone is supposed to be cheaper and much faster than the current version. So for the price difference you could buy a little eyepiece. See who's calling, scroll the contact list, etc. lol they could call it the iPatch yukyuk.
  10. revives fossil post -- Thanks CraigD that actually brings to light more fodder :confused: The other reason I was asking was that current space vehicles are small. The bigger they get the more you'd need to move around actively. Where you could argue that regardless of Mir or ISS or a space shuttle being in space or on the ground, a full gee, the passengers just can't move around that much and might not be able to move around enough to be as healthy as a person free to walk around. So in a much bigger microgravity environment, inhabitants would still need to move around. The more they
  11. I've been reading the commonwealth series and wondered about the logistics of a global train service, or at least a train that goes around the world non stop. I want to spend some time specking out the system but need some fodder. The concept is speculative but could become a reality at some point down the line. I'd like to know your opinion of just how realistic or unrealistic it sounds to you. Which route would make the most sense in terms of distance and passing through the most nations along it's circuit route. Having a helium filled tube (to keep it pressurized) running around th
  12. That's partly the point of the question Buffy. Landlubbers may find it funny if that was the cost of adapting to microgravity environments but if it wasn't a bother to the people in orbit, the health as the main concern. It would mean being in orbit for extended periods of time is only problematic if you plan to return to earth. Some of the sci-fi I've been reading, Chris Moriarty, lately talks about adapting to microgravity or low gravity environments. Humans may not be so badly off in space if they grow up there to begin with. If a kid isn't exposed to gravity for most of their life coul
  13. Quick question: What's your opinion on chidlren being trained as astronauts (being sent up into space very early so they have a greater affinity with microgravity) and doing their studies in space. Wouldn't children get used to being in microgravity faster than adults? Living and working in a 3D environment without a gravity bias? Have their been any studies on how quickly/well children adapt to microgravity?
  14. How fast would a mass, say a baseball, have to be travelling before standing water would react like a solid, vaporizing it on impact (perpendicular, gravity not withstanding)?
  15. i'm just slightly more interested in this game again since EA has partially announced that Simcity and The Sims sequels can be expected in the next fiscal year. (yeah right) but otherwise this game still looks Too dumbed down to be fun. i just burned my fingers on Sid Meier's Railroads thinking it would be a serious attempt to revive the old ghost.. no such look. all games these days are built so any idiot can play.. its sad when the die hard fans have to try harder just to make their own fun. -- i'd be more into the intrplanetary commerce.. but something tells me the experience won't
  16. a) 2 xbox consoles (one repaired a few times), and a 360.. buying an MS made toaster wouldn't be a huge stretch, if it meant D3D10 support and VIsta even if it was watered down (dealing with VIsta daily i'm hardly going to be able to part with it once the betas expire, and i'm more comfortable buying hardware with VIsta preinstalled than paying 499$ to continue enjoying WVU) :) The truth about MS hardware is that they were inept. Xbox has tought them more than any prior hardware initiatives. Xbox was virtually perfect (except for the piracy thing). it demonstrates that MS can cobble together a
  17. quick question regarding the bacteria: if in nature these methods of energy conversion evolved so long ago, and apparently work so efficiently, were these most efficient processes the original ones or did the efficiency increase as the bacteria evolved (in that as the bacterial cultures were carried around the planet they encountered and absorbed new chemicals/minerals and adapted them into their metabolisms for increased efficiency)?
  18. so even if you're running only games, and a much watered down OS that unlike for a true VIsta PC isn't going to be the workhorse, expected to have all that functionality.. it would still be too inefficient to bother with? also would it at least theoretically be slower if all of it was Proprietary? because MS already has Xenon in its pocket, the OS, and most of the programs, could they not be tuned to the nth degree for maximum performance? again knowing that gaming performance would be the first priority? and when gaming the OS would virtually shut down to only its barebones essentials t
  19. Can an OS be built that can run on both IBM Power PC based processors and an Intel (or more specifically x86 processor) at once? where it could run on the AMD(+ATI graphics.. a tailored version of Xenos) processor and send processes to the IBM Xenon processor that couldn't be handled by the AMD? context: If MS was to build a Unifying hardware platform for Vista and MCE, such that the hardware could run Games for Windows (with full D3D10 support) and 360 platform games in one unit, nestled between the full Vista PC niche and the cheaper end 360 hardware niche. noting also that the middl
  20. kinda makes you wonder why humans at the top (so we like to think) of our food chain.. manage to live so closely together in such high numbers... if Homo Sapiens were bigger and stronger, self sufficient, would we still be communal?
  21. thats fine i was asking about earth and extrasolar planets that may have escaped their stars or the possibility of a planet forming on its own without a star.. if there is liquid water and radioactive material.. as well as a big enough planet and diversity of composition in the warm part of the curst if life could form and survive without a nearby start to power their metabolisms.
  22. quite so as i was wondering about robbing Venus of atmosphere that would be broken down in transit to Mars. subjectively much more difficult and pointless than bring earth water to mars.. storing Venus atmosphere in tank on Mars until there was enough to release it all at once.. though dramatic and rip-off of Total Recall may be beneficial to a Mars colony as well as Venus colony. clearing up the atmosphere for ground settlements might take centuries who knows.. but space on earth will become a premium and mars will like like prime realestate at some point down the line S.A.R.
  23. based on your post C1ay i'd wonder how much energy that really is. earth radiates energy also, and being so far from the sun Jupiter doesn't recieve quite as much energy as earth does. it might be something like earth outputs 2% versus the amount of energy it receives. with Jupiter putting out 200% versus what it receives its gotta be higher than what earth puts out but still nothing close to what hits the earth that we can convert directly albeit inefficiently to electricity. i.e. circling Jupiter in close orbit with a solar panel pointed down at the planet would be pointless. you'
  24. i thought it had more to do with the size of their overall ecosystem/biomes. where a species, as in a group of animals where invidual creatures interbreed, grows larger because they have more land to roam and live longer, they will become much bigger. i wonder how long sauropod live spans were. given they were reptiles that would point to very long life spans indeed. also on tiny islands you get pigmy creatures yet on massive continents you get super large creatures like the sauropods. no to mention the largest living creatures are ocean borne. because its such a huge ecosystem. i n
