Maxim 8-Jan-2007 [1533] | QNX can be made to run on printers ;-) |
Geomol 8-Jan-2007 [1534] | Maybe Tao Group moved away from Elate and now consentrate on the "intent" part of it!? |
Maxim 8-Jan-2007 [1535] | hum looking up Tao... to refresh my mind... its been sooo long. |
Geomol 8-Jan-2007 [1536] | Elate seem to be called intent-RTOS now. |
Pekr 8-Jan-2007 [1537x2] | QNX is cool. Maxim - I thought you were talking QNX :-) I saw QNX demo by Dan Dodge in Cologne Amiga show 1998 - it was breath taking - imo the best mikrokernel architecture around ... Kernel just 75KB, everything else runs dynamically in user space ... |
QNX is now owned by Harman International (Kardon) | |
Maxim 8-Jan-2007 [1539x4] | IIRC it can even multithread code with no threads within the source! sort of because of the way it distributes processing. IIRC each operation is a single call and if the kernel detects that it can push a few ops in parralel it sends all of them at once... so single process code can actually run on multiple CPUS with no programing on your part. |
its also the reason you can multithread on several machines so smoothly... it only sends individual opcodes through the wire! | |
that is what I remember of the tech demo a while back. | |
(I wasn't there... just what was explained) | |

Maxim 8-Jan-2007 [1544] | hehe seems a bit like my AWE concept I shared with Ammon a while back... Adaptive Work Environment. |

Chris 10-Jan-2007 [1546x2] | Looks nice all told, 'cept maybe the square shape doesn't lend itself to ear->mouth contours... |
That is to say, as a PDA or iPod variant, it looks great. As a phone, it looks like a brick. | |
Gabriele 10-Jan-2007 [1548x2] | i guess they assume people use a separate headset... |
though, basically all cell phones I have used today are bricks. | |
Maxim 10-Jan-2007 [1550x2] | the flip ups have a better ergonomy in this regard, since they leave both sides at an angle... |
but mordern phones don't really care about proximity... the mix is designed to capture sound linearily within a foot AFAIK. | |
[unknown: 9] 10-Jan-2007 [1552] | I would like wireless headset that recharges from teh phone when put in the phone, the phone recharges when placed anywhere on my center panel of my truck, or my desk. |
Anton 10-Jan-2007 [1553x4] | Aren't there crystal radios which require no batteries ? |
Why couldn't the phone send out a weak radio signal which a crystal radio headset picks up ? | |
duh.. that would be a one way conversation. :) | |
sorry, I didn't think that through ! | |
[unknown: 9] 10-Jan-2007 [1557] | : ) No worries. Good point, one could always have a Whole car Tesla Coil LOL |
Anton 10-Jan-2007 [1558] | Would that still be a car ? I think the nature of the car would have changed if you did that. |
[unknown: 9] 10-Jan-2007 [1559] | No, but it would be heavy, since you would hauling around a giant spool of cooper wire. So it might only get 3MPG, but hey, your headset would not need batteries! |
Anton 10-Jan-2007 [1560x2] | But if you're gonna do that, you might as well take advantage of the huge magnetic field made possible by the coil. Perhaps it could be a form of locomotion.. :) |
Roads should be built of rare earth magnets. | |
[unknown: 9] 10-Jan-2007 [1562x3] | It does not work that way. You would have to have a giant coil in the ground, and the car would be the object (creating a magnetic field). In fact this is the way street lights know when to change. There is a coild of copper in the ground. You might notice octagonal cuts in the ground even in Australia where they place these. |
If the road was made of magnets, then when you dropped your pen knife, you could not pick it back up. The ground would quickly be covered in paperclips and screws. | |
(sorry, I just realized you were writing tongue in cheek). I'm working on a technical paper, and was in "literal mode") | |
Anton 10-Jan-2007 [1565x2] | Sensors could sense the car's magnetic field, then switch on the opposite polarity in the ground magnet, so magnets are only powered when there is a car nearby. |
(only half tongue in cheek.) | |
[unknown: 9] 10-Jan-2007 [1567x3] | That is possible, but so expensive it would be better to have minimin wage works carry you to work and to the market. |
They can fan you too. | |
If you are hot... | |
Anton 10-Jan-2007 [1570x2] | That's so last millenium, though. |
You've got to have floating magnets involved somehow ! | |
[unknown: 9] 10-Jan-2007 [1572x2] | True, but cheapper than magnets...and more fun really. |
The Germans are working on it....I hear it is getting cheaper, but still not cost effective even for a monorail. | |
Anton 10-Jan-2007 [1574] | I wonder about those stories sometimes. |
[unknown: 9] 10-Jan-2007 [1575] | Also, you still have to have a giant power source, and it would not be availble everywhere, so you still need to bring power with you. |
Anton 10-Jan-2007 [1576x2] | Microwave dishes on the top of skyscrapers beam power down to where it's needed on the roads below. |
So that works for the city.... | |
[unknown: 9] 10-Jan-2007 [1578] | Actually that does not work, for a lot (insert misc. dead humans and animals in line of site here) reasons. |
Anton 10-Jan-2007 [1579x2] | Maybe a beam which converges to a focal point under the ground, passing weakly through objects above. |
Never mind the power - surely rare earth magnets can be kept in opposite polarity ? In the ground, in the car. So the car floats above the ground. A fan powered by push-bike pedals moves the car through the air like a hovercraft. | |
Gabriele 11-Jan-2007 [1581] | nah, let's just use antigravity. :P http://www.sciencedaily.com/releases/2006/03/060325232140.htm |
Anton 11-Jan-2007 [1582] | Aha! Looks very interesting :) |
