Wow, congrats to both of you! :-)

Great

I'll note that the breakthrough was facilitated by the environment 
set up for me by Bo. It would have been hard to do it without that

SUperprogress guys!

I'll wait for the fossil tutorial video ;-)

Congratulations! Good to hear, that these projects are used for something 
real.

1st video nice song and clip.

2nd video Lizzen vewy cawefully, Eye willl zay zhis oonly whonze... 
is distracting me, trying to watch that tomorrow again
3rd video demo? Demo of the symbolic view in Mac finder :)

Fortunately, Respectech has several cloud servers.  I had my system 
administrator create a couple of Windows 8 x64 virtual machines so 
we could simulate a Windows network environment with Solidworks.

guys, is your project the surveilance camera related, or a newe stuff? 
As for the breakthrough - some kind of optimisation, or some important 
functionality, etc?

A new project. The breakthrough is the coming together of the key 
functionality that is the identity of the product

@Arnold: once you finish with the PRNG algorithms, you could have 
a look at Lz4, I would love to have it built in Red! ;-) 

https://code.google.com/p/lz4/

It is like Kaj is performing brain surgery with the lower levels 
of Windows.

Doc also did some of that with Red where he developed a non-Microsoft 
method to interface with the Microsoft kernel.  Microsoft doesn't 
provide complete documentation for doing that sort of thing, but 
he did it anyway.

@Doc, I will take a look at that. It is another thing of magnitude. 
Downloaded the source for starters.

@Bo, you understand why Kaj need to drive the Windows Kernel. M$ 
is not able to do so anymore?

Testing user.reds by Rebolek. 
one-eight: 0.125
testint: 4
myresult: 1.0 ;initialize as float
print [" myresult was: " myresult lf]
myresult: one-eight * int-to-float testint
print [" myresult is : " myresult lf]
myresult: myresult * 2
print [" myresult is : " myresult lf]
Guess the result game..

Results I get: 
 myresult was: 1
 myresult is : 0.5
 myresult is : 1.3563418576693e+243

Ieks!

I seem to remember that floats and integers can't be intermixed yet

As the float functions from the mt19937 source depend on int-to-float 
conversion, this better be tested some more.

that is why int-to-float from user.reds by Rebolek from the contributions 
link was recommended to me earlier.

int-to-float seems OK here, but not * 2: try * 2.0

Or even * int-to-float 2

Ah sure! Good you are here tonight.

How easy it is to make this error!

It would be better if it gave an error

Better so indeed or just compute to what it should be.

Sure, but then something else would be unimplemented instead

This looks much better again.

Now it prints that 0.5 times 2.0 is 1 (note not 1.0)

Yes, that's a bit unexpected

myresult was: 1
 myresult is : 0.5
 myresult is : 1
It did also on the first printed line. Could be a design choice.

int-to-float causes a error. Or does it? I added some prints and 
inbetween steps
	genrand-real2: func [
		return: [float!] 
		/local result [float!] between [float!] intermediate [integer!]
	][  
	    intermediate: genrand-int32
	    print ["intermediate: " intermediate lf]
		;result: int-to-float genrand-int32
		between: int-to-float intermediate
        print ["between: " between lf]
		result: ((1.0 / 4294967296.0) * between) ;; divided by 2^32 
		return result
	]

ON the second value the program errs:
intermediate: -1734706621
between: -1734706560
-0.40389284491539 intermediate: -1052231088

*** Runtime Error 9: float invalid operation
*** at: 00002033h
logout

When I make my testprogram for user.reds tell me why int-to-float 
behaves like this:
intval: -1052231088
floval: int-to-float intval
print ["intval: " intval " lets floval become: " floval lf]
The output is not a runtime error:
intval: -1052231088 lets floval become: -1052231040

But the print line was not executed in my real program? I only have 
one user.reds file in my directory. Suggestions?
