huge security risk if you site hosts pdf files
huge security risk if your site hosts pdf files apparently.

Did anyone took a look at this stuff here? http://llvm.org/
Looks like a generic VM approach usable for all kind of languages.

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 ....

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!

Maxim - so suggest Carl to give us that functionality with WildMan 
:-)

you know what ... I just realized that I had a brain split  :~/  
  the above are functionalities of QNX  !
Tao is a Java based VM.

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.

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 ;-)

Maybe Tao Group moved away from Elate and now consentrate on the 
"intent" part of it!?

hum looking up Tao... to refresh my mind... its been sooo long.

Elate seem to be called intent-RTOS now.

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)

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)

hehe seems a bit like my AWE concept I shared with Ammon a while 
back... Adaptive Work Environment.

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.

i guess they assume people use a separate headset...
though, basically all cell phones I have used today are bricks.

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.

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.

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 !

: ) No worries.  Good point, one could always have a Whole car Tesla 
Coil LOL

Would that still be a car ? I think the nature of the car would have 
changed if you did that.

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

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.

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")

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.)

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.
