  2. Yeah.... on Traffic Control of the Future · · Score: 1

    But giving EVERY car in the nation a foolproof automatic guidance system is that much cheaper. Not to mention the time till every old car is kicked of the road (because even a single car WILL create a huge mess of such a crossing, plus even ONE faulty guidence system will do the same).

    And if 2 cars hit each other and convert a lot of their kinetic energy in waste metal, then NO guidence system can stop the next 50+ cars from wrecking into them. Even the fastest regulation circuit cannot simply make kinetic energy dissapear.

  3. oops, on Traffic Control of the Future · · Score: 1

    ok, the cars are SUPPOSED to nearly crash at the intersection. Sorry, ditnt RTFA...

    But: If this control system would be THAT perfect, you could easily increase traffic saturation by 300% by removing any safty distance between your cars. If its safe to near miss each other at the intersection, it shoulnt be a problem to drive with only 1 or 2 meters to the guy in front of you...

  4. I dont get the simulation.... on Traffic Control of the Future · · Score: 1

    Why do cars drive through each other at the intersection?
    If its just 2 independent lanes, why the cross-layout?

  6. Re:Agreed... on Globalwin Jefi Watercooling Kit Reviewed · · Score: 1

    THe nice thing with watercooling is that you can have a performance system, VERY silent, if you are creative. Those systems with in-tower-radiators (even g5) suck. If the heat is already in the water, why cool the water with hot air from inside your case, or blow the heated ait inside (depending on airflow direction)

    The inside of the case is normaly suffed enough.
    I have a nice big external radiator, which is able to cool my pc sufficiently even in the summer (without AC) without any fan on it at all.

    Because there is no cpu heat inside the tower, my radeon 9500pro is cooled just fine passively by a Zalman cooler.

    My 8 harddisc need a little forced cooling, but a 12cm fan running at 5 Volt is ok (my case has a rack of hot swap bays with airducts to that fan).

    The system may be a little hot, but is rock-stable. How i am able to make this claim?
    Easy: Last summer was the hottest around here, and the system had an uptime >60days at he end of august...

  8. Re:Mach Question.... on X43-A on to Mach 10 · · Score: 1

    So a jet pilot traveling at 10km will produce a sonic boom only at mach 1.4 (or whats it exactly)?

    If thats true then the whole "mach" thing seems rather pointless..

  9. Mach Question.... on X43-A on to Mach 10 · · Score: 2, Interesting

    Are those mach speeds representing the actuall factor at flying altitude or is there a standart altitude?

    Because if its at traveling altitude, your mach 6 35km altitude vehicle would be faster then your mach 7 15km vehicle (speed of sound is presure dependent).
    But if it were otherwise, you could travel at mach 1.1 and still be subsonic if you are high enough, which doesnt make sense either.

    So why dont they just give the speed in km/h (or mph)? Mach may be usefull if you are dodging around the speed of sound, but at mach 2,3 (or 10), who cares?

    I simulated combat scenarios, racing cars, passenger jets, mass troop movement, ect the last few weeks with my computer.
    Simulation IS to be done for a reason. Your computer simulates your oppossing soccer team in fifa2004. Is simulates driving physics in F1 Grand Prix or Colin McRae. It simulates a whole city in simcity (heck, there is even a whole genere called SIMULATION).

    And even if you leave out games, there is stock software, Seti&Folding@home (both simutlating stuff), ect. Put povray and all the other renderers in the pot, because they all simulate a multitiude of physical effects.

  18. Too little too late.... on POV-Ray 3.6 Released · · Score: 3, Informative

    8 Years ago powray was slow, but quality wise better than most commercial renderers.
    Since then not much has changed with povray, but A LOT with the rest.
    Now povray is still slow as hell (the radiosity core is RIDICULOUS. it takes longer per scanline then others per picture while still having artifacts)

    Look here:
    http://www.pointzero.nl/renderers/
    and find at least 10 other open source renderers that were developed in less time than the povray-tram needed for this half-assed update, are 10 times faster (or 100 times if you use some sort of GI) and feature the ability to render stuff other than their own format (e.g. plugins for blender/3ds/ect).

    You signal/noise ratio WILL NEVER be limited in practice by the 112db of your cd. Simply because termal noise in your Transitor-juction regions will be bigger.

    Any box of acceptable quality (so no boom-horns that make your rave loud but have 20%jitter) will yield between 85 and 90, perhaps 95db/m*W (95 is a real upperlimit, only reachable by transmissionline boxes or other stuff).
