I know. OK, maybe I need an advice. I was looking into some C code 
educatory example, which contained something like:

char multi[5][10];

decomposed to:

    multi[0] = {'0','1','2','3','4','5','6','7','8','9'}
    multi[1] = {'a','b','c','d','e','f','g','h','i','j'}
    multi[2] = {'A','B','C','D','E','F','G','H','I','J'}
    multi[3] = {'9','8','7','6','5','4','3','2','1','0'}
    multi[4] = {'J','I','H','G','F','E','D','C','B','A'}


which gets stored in a memory block of a "0123456789abcdefghijABCDEFGHIJ9876543210JIHGFEDCBA" 
value.


If I would be supposed (for any reason :-), to interface to such 
a construct, I would simply use a pointer in Red, and would be responsible 
to manually decompose/treat the value of arrays, not to break it 
for the C level code?

Yes. (And there's hardly a breakage you could incur.)

Note that in C, multidimensional arrays are really just a convenience. 
So a `char[5][10]` is actually identical in memory to a `char[50]`.

And, as you know, an array type and a pointer type are (for most 
things) interchangeable, a `char[50]` is the same as a `char*`, therefore 
a `char[5][10]` is also the same as a `char*`.

OK, thanks. So btw - how are REBOL blocks (most probably), implemented 
in the C level? As structs of "arrays", chars?

Andreas: No possibility to be multi[0] and multi[1] are not interleaved? 
I mean, couldn't be 2 different memory blocks instead of continues 
one? Normally it will char[50] but same for all compilers? all memory 
models? small hardwares etc.?

Petr, it is true that typed function arguments can be used to implement 
blocks to some extent

REBOL blocks have larger cells

Endo: it's guaranteed to be a single, contiguous area of memory. 
So yes, that behaviour is the case for all compilers and all memory 
models and all hardware (if they claim compliance with the C standard).

Endo: thanks for avoiding me to repeat myself over and over. :-)

When I will write app in Red, it will compile to Red/System in the 
first pass, and then to the native code from R/S? So that it means, 
that you write Red in R/S? Hmm, if Carl would release R3 sources, 
it would not help you much, as you plan to write Red in R/S, not 
C?

Pekr: "Doc, do I understand it correctly, that lists/arrays are now 
supported via 'typed funcitonality"


No, it can look like "lists", but there are only function calls with 
arguments.

Arrays might be supported in future though, if we really need them 
for implementing Red.

If you make an array of typed structs, you effectively have a block

What is that? :-)

someone's idea of a banner for red supporters

uglyyyyyyyyyyyyyyyyy :-)

do better

I do like work of one Agency here - http://loganamiru.cz/, they 
did my 2zone media :-)

C'mon Graham, I'm not a  graphic designer but people still have some 
common artistry. :-)

I like e.g. part of this one -if you would turn the arrows 90 grades, 
it could imitate REBOL prompt sign >> RED - http://www.logofactory.cz/msys/uploads/logos/48.jpg

we could ask Fork ... if he's still around

A simple vector style of Red Riding Hood's hood, maybe with one twinkling 
eye peeking out, and the tag line "Don't be afraid". :-)

or ...Judy Garland's slippers ... make a wish :)

( Dorothy in Wizard of Oz and sorry they were ruby red slippers )

We can't work like that imo :-) I went thru the process several times. 
We have to define qualities we want to reflect, etc. But RED, red 
is "just" a color. What can represent that? Something red, perhaps 
:-)

symbolism is that your wishes will be granted if you try hard enough, 
and the impossible is possible.  We don't need the wizard of oz to 
help us.

in this case, the wizard is Carl :)

And if anyone finds red, it's a perfect fit ...

Simple 10 minutes creation ...but I don't like how it turned out 
:-) http://xidys.com/pekr/rebol/red-logo1.jpg

using 2 different fonts ..looks unbalanced

can the ED be bolder?

What about 

>>RED
talk dialects


the >> is a play on the target image used in REBOL where >> is both 
from a console,and also an arrow head?

Still not there :-) http://xidys.com/pekr/rebol/red-logo2.jpg

But having fun :-)

Yes, for >> I can use some pictograms ...

too much text in that one I feel ...

I know - the bottom slogan could be replaced by link to webpage ...

Few more creations, still not there ... but -time to sleep ...

Maybe the Red pill as Doc alludes to. Or let Doc tell us what he 
wants the logo to symbolize.

Interesting selection of designs

Interesting designs indeed, I will try to list my wishes after the 
Devcon this weekend.

Their are nice-looking, but maybe too "corporate"?

They

I like the stylized "R" in the "redlang" logo.

Yes, Redlang is probably the best one, and yes, they are maybe too 
corporate. I am more for a serious stuff, than for a fun ...

Also - I am not a designer, I used one nice tool - http://www.sothink.com/

Those were just tries. Any of the above logo is imo better than what 
Graham originally posted. But I am not satisified either. Here's 
my take, what needs to be considered for the logo to actually "work":


- you should define a brief - namely a description of qualities/characteristics 
of Red. What is Red, what sets it apart, what does it mean to you, 
what should it mean to ppl, what differentiates it from others, etc.


- type of logo - only letters? Letters plus pictogram? Shoul pictogram 
only decorate logo, or is part of the name? Pictograms are often 
related to the business, but I am not sure, if you are easily able 
to relate pictogram to "red", as it is a name of the color. Nor am 
I sure, if pictogram would express a programming language. What I 
would suggest, would be either - pictogram contains "R", which also 
works as a filetype icon. Or pictogram expresses some quality - e.g. 
>> (REBOL/Red prompt), [R] block as one of the main concepts (series)


- color scheme - not much options with something named Red, right? 
:-)


- usability - you should think about the color scheme, and logo in 
various forms - normal, inverse, black&white, icon, letterhead, business 
card, ppt presentation, etc. You can look for inspiration to how 
I aproached 2zone media logo with the agency - http://www.xidys.com/pekr/2zone_media_logotypes/
