Thank...has my password been cracked or are they means to post in 
name of someone else?

(tweet deleted)

I've changed my password just in case.

Can someone tell me why for example in https://github.com/dockimbel/Red/blob/v0.3.0/red-system/utils/profiler.r
to use 

set 'make-profitable func [][] instead of make-profitable: func [][] 

because the second kind of declaration is also use in this script 
and I do not see why both are being used; you have a preference for 
one over the other so you use one, not both?

set 'make-profitable func [][] instead of make-profitable: func [][] 
the link overwrites this line in my version of AltMe sorry!

This also was meant for Rebol-school. Closing down AltMe and restart.....

Arnold - that's the old altme url bug. In order to be able to read 
such lines, just change the size of text for a while (aA button above 
the text field)

Arnold - 'set example is one trick you can use in REBOL. Normally, 
when you enclose the function in the object/context, it is accessible 
via a path notation, e.g. context/make-profitable. When you use 'set 
aproach, it lives inside the context, but is exposed to the global 
context, so you can call it directly, or something like that :-)

Thank you Pekr. It is a little to subtile for my mind and current 
REBOL knowledge, I will have to live with this ;-)

It's "make-profilable", not "profitable"...well at least, not yet. 
;-)

LoL! I was totally unaware I changed that. :D

:-)

@Arnold: I've pushed an update to profiler and I've made nested functions 
exposition to global context more elegant. ;-)

Maybe it is more profitable now :D

Good point, I'll see how Doctor Manhattan renders in red shades. 
;-)

This is huge: http://www.pythontutor.com

We need to write Red documentation that way too!

Cool! (for FB group and pythontutor.com)

Really nice - I thought the examples were canned at first, and I 
was thinking how tedious it must've been to set these up, but I see 
that it's all generated on the fly.

I would've thought that trying to show so many things (program listing, 
output, data structures) in that amount of space would make it hard 
to follow - it's surprisingly clear, though.

Well my patience is being tested. No red-lang mailing list for me 
for a week or more. Account disabled. (Red-terrorist :) )

Ah, Unicode plan posted, should be announed here :-)

http://www.red-lang.org/2012/09/plan-for-unicode-support.html

Any particular plan for error handling?

Nothing in particular, I will implement it the same way as in REBOL. 
If you have suggestion about improvements, it's still time.

Error handling will come fast, probably next week, but in a basic 
version as we still don't have something like system/standard/*

Pekr: I guess that all people here interested in Red have subscribed 
to red-lang.org feed. ;-)

yes, but? :-) You posted about FB group above ... which is part of 
the Twitter feed too :-)

what I liked about R3 errors was addition of 'why function, which 
pointed you to the docs :-)

Pekr, yes, exactly one thing I'm missing about the current error 
system. Also currently user error strings are difficult to localize 
unless you use your own scheme, when displaying the error.

You can certainly carry this data in the arg1, arg2 and arg3 words, 
but it's a bit awkward.

About error, maybe some indication of the line number. Not prominent 
but as a hint at least, however using find most of the time finds 
the right place where the error is, sometimes it is not so clear.

Henrik: you're are passing REBOL errors to end users?

Line numbers: there are complicated and costly to handle in a REBOL-like 
language at runtime. The experimentation I did in Red/System confirms 
it. I'm not sure I will add them to Red unless we can come up with 
an efficient solution.

*they

Dockimbel, well, maybe it's bad design, but what I do generally is 
make error! in the deepest part of the code. When such a user error 
happens (which is generated by a plain make error! "something failed"), 
I disarm it and display arg1 in a dialog in the higher level code, 
if that makes sense. This way, errors are easy to identify and I 
don't have to make up schemes for return values. When a REBOL error 
happens at the same level, I let the program crash.

Arnold, in R3 there is a stack trace shown at the error message, 
which lets you find errors much quicker than in R2. Line numbers 
aren't really practical with REBOL.

Is there any "tedious" task (not involving manuals, docs or graphics) 
that could be done by some volunteer to speed up Red development 
?

question about compiler.r 
while		[intrinsic! [cond  [block!] body [block!]]]
until		[intrinsic! [body  [block!]]]
no condition needed for until?

(I know it is the value of the last line if it is a condition in 
rebol but shouldn't it be specified?)

Nope. There is only one argument, the body.

Those are just argument specs. They don't specify behavior eyond 
that.

Marco: besides coding in Red/System, I don't see what you could do 
currently to speed it up. Here are some ideas for the additional 
coding that will need to be done:


You can write in Red/System some of the non-trivial natives, like 
e.g. set natives: sort, union, intersect, unique, difference. Other 
natives or support code we will need are codecs for:

- compression supporting these algorithms: deflate, lzo

- cryptography: MD5, SHA-1, AES, ...(all the required ones for SSH 
and SSL support)


You can port C code to Red/System, there are tons of available C 
source code, you just have to make it right (crypto requires accurate 
coding, implementations need to be deeply tested for flaws).

Alternatively, you can try to find a good existing open-source SSH/SSL 
lib that is BSD-compatible, so far, I haven't found  any. All the 
robust open source ones that I could found are under GPL.

ok, just like in REBOL of course. Still it looks strange because 
I expect it to be there because there always is in other languages 
and it is a loop until a condition is met. So somewhere that condition 
must be tested to be true or false but indeed this part is more the 
definition of how the statement as a whole should be formatted in 
a Red program. I'm back on track, thanks!

cryptography: maybe I can handle ROT13. :-)

Marco, maybe you could do a syntax coloring scheme for one of the 
popular editors out there

I guess this would be more straighforward for Red/System as opposed 
to Red because of the more limited syntax. I would think a regex 
based approach would work for that
