World: r3wp

Ladislav: I get different results from you. I'm running A49 on Mac 
OS X:

>> fastest [t/(x)] [pick t x]

The first code took 0:00:00.003794

The second code took 0:00:00.004753

>> fastest [t/:x] [pick t x]

The first code took 0:00:00.002759

The second code took 0:00:00.004285

What OS did you run your tests under?

By the way, it is probably far too early to come to any conclusions 
about the relative speeds of different functions in R3 as I believe 
the code has not been optimised yet.

Brian: then my memory is that R3's value slots are not fixed size 
any more, because they will be bigger on 64bit systems, but the current 
version is still 16 bytes per slot. so, you can't trust it being 
that way across versions, but i don't think there are versions that 
use more memory yet.

my OS: Windows XP Prof SP3

Didec, i have the same results than Peter with the A49.
And what you're saying is not the problem i pointed.

See, there something strange with the number of evaluations done.

>> dp [loop 1000000 [pick t x + 1]]
== make object! [
    timer: 517292
    evals: 4000011
    eval-natives: 2000004

>> dp [loop 1000000 [t/(x + 1)]]
== make object! [
    timer: 350263
    evals: 3000011
    eval-natives: 1000004


So the conclusion is that evaluating a path don't  follow the same 
scheme than a block evaluation.

actually resolving a path is faster than calling a native function, 
it was not the case in the past

my Linux results (Mepis 6) show the same pattern as Windows XP

aha, you are using A49, sorry

A49 yields:

>> time-block [t/:x] 0,05
== 1.23858451843262e-007

>> time-block [t/(x)] 0,05
== 1.9371509552002e-007

>> time-block [pick t x] 0,05
== 4.35829162597656e-007

So why is 'pick so much slower?

It may be caused by the change in function algorithm passing, which 
is more complicated, due to multithreading support

algorithm - sorry, I mean argument

It would be good to probably ask Carl on Chat, no?

Gabriele, thanks, I trust your memory better than mine about this. 
This is definitely a good reason why Carl is trying to do Rebin before 
he releases the host code - reducing direct access to internal data 
structures.

So why is 'pick so much slower?

 It might be because of the overhead of looking up the word 'pick 
 to get the function :pick every time, same as in R2. It's not that 
 PICK is slower, it's that path decoding is drastically faster in 
 R3 than it is in R2.

Is REBOL3 going to integrate into the browser at some point?

It seems that was always promised but I don't see where that is becoming 
a reality.

Remember that you asked that question before you ever complain about 
how we've been working on security lately instead of (pet bug). We've 
been catching a lot of flack lately for working on changes to the 
security model, changes that are necessary to make a browser plugin 
that won't get marked as malware. This was the original reason why 
R3 was started :)

Ladislav, I'd like to make your article on Identity into a cookbook 
recipe, so it gets an official listing in the cookbooks list, so 
people can find it. Where do you think it would fit on this page:

http://www.rebol.net/cookbooks/

arg yeah rebol plugin is important and it's a bad thing if people 
considers it as a malware T__T

Recent Flash releases are the thing to beat. If we aren't at least 
as secure as Flash, consider R3 to be malware.

impossible cause rebol is nice like a puppy :P

Remember what puppies can be trained to do :(

well ... if you want to screw Pcs why using rebol anything else is 
 already enought to screw a poor PC

I mean Vb script for example lol ... well ...

Not my PC :)

Mine neithere i removed VB from my windows :P

i have the same XP since 2002 ... T___T Microsoft is borring

Running a vbscript is not the same thing as running a vbscript in 
a browser. Browsers are for running malware, hopefully without getting 
caught by it. Hence the sandboxing, security restrictions, etc.

brianH the solution is to create our own kick ass browser in rebol 
 :P

It's on my todo list, no html though.

this way no need of having to maintain 3 x3 rebol plugins ... lot 
of saved  time for Carl i will say

I think ReBrowse will become more important than a browser plugin.

There's no point to creating a web browser, even a kick-ass one. 
Look at Chrome: It is better in almost every way, but it only has 
< 2% market share (when last I checked). If you create a new browser, 
people will still use their old, crappy IE or Firefox.

That's why ReBrowse won't be a web (html) browser.

Henrik: rebrowse vs plugin.... entirely different targets.

BrianH ... when what screw the fucking browser statistics is the 
fact 95%  of computers are wndows based and 100% of them comes with 
IE ...

but that doesn't means I use it (I use chrome, opera and firefox)

and unless the web gets replaced by rebol, the plugin will always 
be more important to "the industry" I mean, to get others to use 
rebol in THEIR environment.  which is the biggest weak spot of rebol. 
 it is Hermetic.

Maxim web replaced by rebol yeah that's the idea brillant  ^^

you can't tell a company that invested several years to start over 
from scratch.  it has to be able to migrate without changing the 
habits... rebol has to sink into the other model first, then slowly, 
if it worth it, people will start putting rebol in the center and 
eventually, something like rebrowse can replace the current framework 
or maybe even live besides it while the migration takes place.

I've suffered of trying to get rebol INTO companies and it never 
works.  there is too much ground work to do, it costs a lot of money.

a few throw-away utilities isn't the same as building the company 
IT over rebol.  its an entirely different ball-game.

yes we can :P YES WE CAN :P and i'm sure all of them will really 
like to do it ;P

the whole IT industry -> But damn but how but ... buuuuuuuuut so 
many years spent doing borring things now that we discovered rebol 
our world have changed !

R3, will allow us (finally) to merge rebol INTO other stuff, so it 
can become the controler for lower logic, but when that starts, people 
will usually start writting everything in rebol... cause its just 
plain productive.

like Lua .... but ppl will say but Lua already do it and it's better 
damn people ...

Ever tried to use rebol in a company that has only .net, python, 
or java code?  good luck.  it takes weeks before you can use most 
of the DB stuff they have built up, because there are sooo many modules 
out there, and they have huge frameworks, which actually DO more 
stuff than rebol .  rebuilding those libs is not even always possible....

ex  integrating DirectX/OpenGL into view... nope.  loading dll classes... 
nope... etc, etc, etc.

but R3 will change all that  :-)
