Devices, codecs? Where?

They are there, just not finished and optimal ...

Where?

There are just some traces of them as an internal implementation 
detail. There's nothing you can do with them

There are reasons that you don't see anybody writing extra devices 
and codecs

Kaj - I think  that you are not accurate, and that you even know 
it?. Codecs are useless, and even Carl later introduced the plan,of 
how to reimplement them. But devices? There is list of devices out 
there, no? http://www.rebol.net/wiki/DevicesThe other fact is, that 
those are not usable via extensions, but it does not mean the abstraction 
is not there?

Yes, they're there, as an implementation detail of the internal abstraction 
of R3. The only place where some devices are exported is in the host 
kit, but they're hardwired there. You can port those specific devices 
to other platforms, but other than that, there's nothing you can 
do with the abstraction

Robert, code, including gui's,  created by other code and then executed, 
is a great feature of Rebol.

Robert: here is a proposition for presenting View + VID + REBOL coding:


1) Show this code on a slide, explain briefly what it does and run 
it: 
REBOL []

view layout [
	code: area 300x200
	btn "Run" [view/new layout load code/text]
]


2) Enter some VID code in the textarea, click Run and listen to the 
"wow" in the audience ;-)

You can type, for example:

across
text "Name:" f: field
btn "Say" [alert join "Hello " f/text]

BTW, you might want to patch the 'button VID style to point to 'btn 
for this demo. "button" would be much better for the code demo, but 
the look of "btn" is way nicer (and more modern).

also, go to nick's page to get VERY cool 5-10 line scripts which 
are impressive.

Thx for the input, I'm going to see how to put all aspects into it.

but one thing you need to highlight, is that for all of your needs 
(code, style, layout, server, client, templates, controls, localization, 
etc) you are using a single highly natural language.    This is the 
power of Dialects, (DSL). 


datatypes are also a great differentiator of REBOL... just run code 
and leave an HTML tag in the code, as-is... that is cool.  most languages 
require literal data to be assigned, but in rebol data IS an expression 
so as long as there are no syntax issues, you can just embed data 
within the code (for whatever reason you need it in source managing 
tools).

I have Dialects using VID and Doc's example to show: data is code, 
code is data.

Datatypes is good.

show that you also use the same language for creating style sheets, 
new controls, sending a VID layout over tcp, etc.  just showing how 
small the code snippets are is enough I guess.


Make a little parallel between the web nonsense, and the simplicity 
of doing the same thing in rebol. (5-7 different languages, vs one)

cause even though people think other languages are simple, they still 
have to deal with using several completely incompatible languages.

(in today's "accepted" programming model)

How many standard words does R3 have?

Is it: length? system/contexts/lib

I'd count the alphabetical listing of words in the dictionnary on 
the web.

>> length? unique compose [(words-of system/contexts/lib) (words-of 
system/contexts/sys)]
== 633

well, ignore sys

what's usable from sys is imported into lib anyways

>> length? words-of system/contexts/lib
== 609

(which, for contexts, should be the same as length? system/contexts/lib 
anyway, but i'm sure brian will chime in on this issue later)

Ok, thanks.

I think I will save the last 40s to even include a Q&A section into 
my pecha kucha :-) because  Rebol is just that compact and simple, 
that I don't need 20 slides ;-)

;-)

It's length? system/words/lib right in a fresh console, otherwise 
there might be new words added.

>> length? lib
== 609

That too, since 'lib and 'sys are predefined in the lib and sys contexts 
for convenience.

Wow, there are three languages less popular
 [than REBOL, on Github].


I wouldn't worry about those stats too much at the moment. It seems 
that projects are re-indexed when there is commit activity within 
the project. So some REBOL projects on Github are not yet correctly 
classified and counted.


On the other hand, the same probably holds true for other recently 
added languages.

so you mean,  we should strive to be the last in the list?   ;-)

IMO C is coming back. Simple, matured, works.

hmm

It probably comes back, but I find it too easy to make mistakes in.
Pro is also, it's fast at execution.
Good libraries might help with the mistakes.

Than D2 is a good choice

Big pro for C is also, that it comes in an ANSI version. It runs 
about anywhere.

that is the exact reason I am coding Liquid in C and not in C++. 
 my project will build on anything out there, or can be easily converted 
to any other language.   furthermore, C allows me to do more advanced 
OOP tricks than C++ allows... things like run-time class mutation 
(required for liquid)

Sorry, @maxvessi : works great under Windows 7 Opera and Firefox 
!

Hmmm strange I don't have a plugins directory (firefox + Win 7 x64)

MaxV: Sounds great.  Is this an implementation of a REBOL plug-in 
without resorting to ActiveX?  I thought earlier attempts hit the 
wall on providing a solution that did not pose an unworkable security 
exposure.

@Steeve: me too, I have to create it and it works !

Many thanks nve, it works now.
MaxV: Awesome work, you're the Reboler of the year

Next,  it's for R3

it works under Windows XP, Opera and Firefox
Can the DLLs be installed automaticly ?

@WuJian: I'm not a software expert, just a Rebol enthusiastic user! 
But it should be possible.

@oldes: Facebook started to freeze groups, during tha next week "worthy 
groups" will be updated to the new style/feature, "unworthy groups" 
will be archived. In both cases all users will be deleted and users 
wil have to join again to the group!
P.S. I sent you a message trough Facebook

wow what a fail!  they could have built it as an "update this group" 
button which the group owners have a time lapse to activate or then 
its archived.

It's like that, I'm an administrator, but not the creator, so I ndot' 
see any button! Is a creator push the button, you loose all users, 
BUT you maintain postos, phots and videos... It's stupid! How can 
you invite again thousands of users?

you know.. managing a single dimension array is quite complex for 
programmers coming out of school nowadays.   


where is the iterator class for "update facebook users list" in jquery, 
 .net,  or java?    ;-)
