Robert 6-Jan-2007 [1522x2] | Did anyone took a look at this stuff here? http://llvm.org/ |
Looks like a generic VM approach usable for all kind of languages. | |
Pekr 6-Jan-2007 [1524] | I once talked to Carl about porting Rebol to some other VM. E.g. Tao, Java, Net ... and/or Parrot .... some guys here mentioned Parrot especially here in the past few times .... |
Maxim 8-Jan-2007 [1525x2] | Tao is really powerfull. being a real time OS it can do things like guarantee bitrates and synchronise parrallel processes on two different machines! |
you can literally move a process from one machine to another in real time, while both are running, and refreshing half of a window on each monitor for example! | |
Pekr 8-Jan-2007 [1527] | Maxim - so suggest Carl to give us that functionality with WildMan :-) |
Maxim 8-Jan-2007 [1528x2] | you know what ... I just realized that I had a brain split :~/ the above are functionalities of QNX ! |
Tao is a Java based VM. | |
Geomol 8-Jan-2007 [1530] | I'm not so sure about that. I think, you were right the first time, Maxim. Tao Elate is a realtime OS, so is QNX. |
Maxim 8-Jan-2007 [1531x3] | if REBOL would port to QNX, they could easily redistribute to almost any hardware. |
Amiga DE uses Tao and its really just a Java interpreter, but the best one out there. | |
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 ! | |
