Ohhh, but is that cool or what?

posted a bit more about it on my blog.

What about the licensing?

Will users need  a pro type license to access libraries?

How does RT plan on generating revenue?

I don't know much about licensing, but I don't think there will be 
any pro licenses anymore. It doesn't make sense when R3 can talk 
to any library to extend functionality, so it would be easy to get 
around that. Revenue? Ask Carl.

How about cost?

free, I suppose

think and suppose make for lousy answers.

thanks for the critique

These are Rebol Inc questions.

Are we going to see an sctp implementation soon?

well, I won't be making it. :-) I think these questions are better 
suited for later. I need to have a better look at devbase. I suspect 
(sorry, Terry) that it will be a 3rd party job.

actually those questions have been answered already, but some people 
like to pretend they didn't notice. R3 will not be sold. RT makes 
money in other ways. (eg AltMe 3)

<--- small FAQ posted here.

henrik, some bugs in your former blog, it might confuse ppl:


1) "Knowing FOREACH from R2, you can assign a word to each of those 
4 elements " .... while your block shows only [a b c]
2) >> a: [1 2 3 4 5 6 7 8 9]
== [1 2 3 4 5 6]

...is wrong too - you miss 7 8 in the ==[] block returned from console 
...

fixed

What a great faq Henrik. Thanks.

Hey, I was just wondering. How big is Rebol3 now (in MB)? Not that 
it matters to me that much but I am curious.

MB? :-)

rebhost.exe - 360KB, rebol.dll - 298KB

Ohh, sorry : ) Wasn't thinking straight. (I am working on a PC, you 
know)

some things are still outside of the R3 distribution, so it might 
balloon a few more kb.

Still incredible, don't you think? So this thing might really work 
on a cellphone/pda?

easily.

Henrik, you know I am a big PS3 fan. How big of a deal would it be 
to port?

I don't know yet much about the porting process, but so far it looks 
like a "fill in the blanks" process, where you need to provide functionality 
for events, timers, threads, etc. That and the documentation for 
whatever OS runs on the PS3. If Linux can run on it, R3 should work 
fine.

It does so I hope that means my next "Amiga" will be a PS3.

The executable size of all versions of REBOL is absolutely tiny.
But the memory footprint when loaded runs into megabytes.

That used to be a showstopper for memory-limited devices such as 
phones/pdas.

It may no longer be if the minimum hardware has caught up with REBOL's 
memory requirements.

R3 typically uses half the memory of R2 right now. Perhaps much less 
on graphics intensive apps.

The cows demo shows that spectacularly.

That's a very promising statistic!

Sure is.

I don't know how much memory an R2 face takes, but a single empty 
GOB in R3 takes 64 bytes.

Well, the proof will be in the pudding. When we get to the point 
where we can run R3 on a Nokia device, we'll know.

I don't do many benchmarks either right now, because my only windows 
box is a 192 MB Celeron 500 that will only boot in fail safe mode 
without graphics acceleration. However it probably is a good thing, 
since it really shows that graphics are noticably faster. That will 
help lowering the system requirements.

(in a new R3 session)

in R2 I have == 6145092

FlashPlayer has same or bigger memory footprint and is on pdas so 
why not R3

Don't know if this is the right place to ask but.. Will there be 
some easy way to access USB devices in Rebol3?

no ....

But if your USB device supports mass storage - most usefull do, then 
what is the problem? You treat is as simply another drive ...

I suppose you go through the OS for that.

R3 is going to have specific access to usb devices

If you need more, you could use the libusb library on Unixy platforms

I'm on Windows.. I've managed to make a small program that communicates 
with the device (it's a small OLED display on my laptop) in C++, 
but it would be much more fun to write it all in Rebol

if you know what DLLs to use, you probably can.
