Just trying to head off another useless, off-topic source licensing 
flamewar :(

at first I did understand what you meant, I started a reply and then 
realized that you where explaining what I meant by closed... so I 
further expanded hehehe... no chance for mis-comprehension now  ;-)

did=didn't

did=didn't
 - LOL, yeah, no chance for mis-comprehension :)

;-)

I have the Reichart chat disorder...  In my case, I litterally see 
and read the word in my mind... not on the screen... so when I post, 
I often don't even realize words are missing or totally wrong... 
;-)

...I have considered moving to "!did" as in "NOT DID" to fix that 
problem.  I really hate that polar words are not MORE different. 
 

For example even better than !did would be "did" and pop" for example. 
 Where "pop" is the negative of "did".

we should all dump all languages and just learn latin... stop the 
language madness  ;-)

to me, latin is to language what math is to physics.  logic, order 
and structure... applied to chaos and randomness  :-)

d;accordus

hehe

I remember writing a program many years ago on my Amiga, that would 
change the input to what I choosed using a simple lookup table. I 
used it to write fast in e.g. IRC, where I would make a table with 
the 3 first letters of many english words. When I wrote 3 letters 
and pressed space, it would write the full word. Could be used to 
change things like !did to didn't. The good thing with the Amiga 
was, I connected to the console device (or what it was called), so 
the program worked everwhere with all other programs using the OS. 
Could also be used to e.g. program fast using shortcuts for command 
words.

Max, makes more sense to switch to mandarin as it is the language 
spoken by the most people

3 letters like asm op codes?

Geo,   I did the EXACT same thing... I had ALL of language E mapped 
in the commodities with some control key being required for the few 
letter words to be converted to  language E equivalent  :-) 


coding was like ctrl+i var=1 ctrl+t ctrl+p "value = 1" ctrl+e   (if 
var=1 then print "value=1" endif   :-)

I meant all languages... AFAIK asians also use language  ;-)

If you used basic .. you only needed the first couple of chars anyway

GEomol and henrick OR YOU CAN STOP USING PAST CENTURY COMPUTERS THAT'S 
GOOD TOO !!! 


>> x: now/time a: 1. b: 2. loop 10000000 [a + b * a / b] now/time 
- x
== 0:00:03
Take that baby

it's R2 on my brand new Intel Core i5 750 / 4go DDR3 1333  Mhz   
with UD3  memory card

gemol if you want i can sell you minutes of use of on my computer 
:P

Take this:


>> x: now/time a: 1. b: 2. loop 10000000 [a + b * a / b] now/time 
- x
== 0:00:03

Heh, my test was about R2 and R3 performance, not to test how fast 
(or slow) one of my computers are. I could have run the code on my 
multi-GHz intel box.

it would be nice for R3 to support LLVM natively..... brian?

but where is LLVM preinstalled? What is the advantage in having R3 
LLVM backend, if I can't find LLVM on my Vista machine? :-)

llvm is a compiler.  its not an OS service.

but its a compiler which can be easily embeded into any application.

mesa3D is using it in their driver engine to convert graphic calls 
to any GPU instructions... on the fly.  implementing a driver becomes 
just a question of providing LLVM instruction maps... although not 
trivial... still much simpler than having to go from HW to OS in 
a single driver  ;-D

we could add JIT compilation to rebol, we could have REBOL based 
extensions which are JIT compiled in real-time, for example  :-)

although we could all of this ourself... LLVM is a nice framework 
to make all of that easier.

so it is not a compiler, it is a virtual machine environment, no? 
What is the advantage here? REBOL is its own VM - if we get it to 
every platform, why would we need LLVM? How big is actually LLVM?

LLVM is a compiler, which you can control in real-time and easily 
embed.

Or you, as a dev. simply use LLVM to create REBOL executable? And 
as you have ti LLVM abstracted, you basically code to one host environment? 
I probably don't understand the model correctly ...

it would make for a powerfull extension, where we could simply run 
a rebol dialect like Rebolek's REBOL syntaxed-C and compile it in 
real time through an extension which serves as a jump vector manager.

so you code in a language similar to REBOL, but end-up with compiled 
code which is linked dynamically in the host...

how big is that runtime?

souce code is 7MB, but probably includes a lot of stuff we can trim 
for our specific purpose. the binaries are big wrt rebol, so it can't 
part of the host code(unless brian can build a very slim version 
of it), but it would make for a very nice extension.

shake, one of the most high-end visual effects software in the world, 
uses a system just like LLVM within their software and it made it 
much faster than all the competition because of it.

if some compiler adds more than 100KB to REBOL, then it is a no go 
:-)

sure, its not for the host, but its still not huge, and makes for 
a nice feature I'd add in any of my speed-critical applications, 
if I had access to it.

for elixir, for example, this would be extremely beneficial.

AFAIK, much of OSX is moving to LLVM.

btw it looks as though I might get some funding to build Elixir  
:-D

also FreeBSD, it seems

Shake is not good because of LLVM-like low level imo, but because 
of properly Graph based GUI. Now allow us something like that for 
View, and you get-me-interested :-) http://www.apple.hu/hun/mac/shake/shake/shake.html

Maybe I'm missing something but you can do graph-based processing 
even with R2.  There is really no special needs at the low-level.

pekr... wrt shake... and what do you think the graph does ?  ;-) 
 


the graph is compiled in real-time everytime you change its structure. 
 you can create your own nodes and add them to the engine, using 
the graph itself as a visual development platform.


 as I said, I worked for those guys... I have an intricate knowledge 
 of how it works.  I also implemented a REBOL implementation of shake 
 callings its rendering engine and intepreting its (C) Header files 
 to integrate all the nodes.  :-)

yes, in R2, globs is such an engine, and it works very well.

Regarding JIT/VMs: Recently I spent some time looking into this area. 
After the short investigation I believe JIT compiler which can be 
really useful(and fast enough) for Rebol can be written in kilobytes 
of code not megabytes.
