you may look into RebGUI project - consumes less memory (mostly non-issue 
on PC), provides more styles, resizing, more proper behavior to styles, 
try to go thru demo AND look into tour.r source - you will see how 
nicely readable the gui part is - you don't need to go into internals 
too much ...

RebGUI, something new to me. In fact, we probabably just need an 
interface to enter data and start some process and show the results. 
Maybe draw a graph with the results - that would be great. Will look 
into it. Tks.

You may want to take a look at Matt  Licholai's quick plot dialect 
for your students to use to plot results. The details are at http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-display-thread.r?m=rmlQBZK

Scroll down the thread to find the location of the source.


There is an updated version of his ez-plot example in the script 
library at http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=ez-plot.r

Maybe you can use Rebol and  try to implement a curriculum similar 
to HtDP.

My preconception is that adding the graphical layer complicates things 
too much 

 -- A valid concern in many environments, but VID is great, and simple, 
 for simple things.


view layout [button "Show help" [alert "Sorry, I can't help you"]]


No need to manage the event loop, no redraw handlers (until you need 
to get into them of course), just put an action block after a face 
style and it binds to it automatically.

Did that "online school" that was talked about ever get tested? How 
did it work out?

Could not find a free tool that allowed al the features we wanted.
The best we found was TeamSpeak for Voice.
It needs Chat (writte), Talk (Spoken), Video, and several Whiteboards, 
and a way to view somoeone's computer screen.
We use TeamSpeak all the time.
Tell me what is out there, and I will get this started.

Google Desktop has a plugin that makes GTalk able to make a chatroom, 
and another that allows you to share part of your screen with someone 
on your buddy list.  I don't know how well they work, thouhg
though*, as I never found anyone else to test it with*

Reichart, can you list the ones that you tried, but failed your criteria?

Can you tell me specifically what I have to learn (master) in Rebol 
(mainly instructions) to code these projects:
Project 1: Read a web page given a URL, find some data in the page, 
append it to a file on disk. Read the given disk file et show the 
data on screen.

Project 1;  Check http://www.rebol.org/cgi-bin/cgiwrap/rebol/documentation.r?script=weblinks.r

Project 2: Establish a two way connection using tcp/ip and save the 
history on disk.

btiffin, for project 1: very interesting. tks
For project 2, it seems to use View... any suggestion without View?

Also (in general) check
http://rebol.com/docs/core23/rebolcore.html
in particular load and save  and  read  and write commands

I'm looking for a LEARNING MAP that could be used as a fast track 
to learning to build interesting little applications.
There are so many options (modifiers) to Rebol instructions that 
it isn't immediatly clear what core essentials should be learned 
first, or what general structure of Rebol syntax should be learned 
to become effective rapidly.
btiffin
27-May-2007
[377]
Yeah, that is kinda in the progess of being built.  There are some 
awesome resources
but they need to be tracked down sometimes....

The cookbook  http://rebol.net/cookbookbeing one starting point.

rebol.org  has a lot of scripts, but it requires reading code a lot 
of the time....
The REBOL Viewtop  (desktop command at console)
    REBOL Folder ->Tools->Word Browser is not bad for options

I'm sure, as the pros keep saying, that once you have learned Rebol, 
it is very fast to code applications. The problem is that it might 
be that to get to that point takes quite a while
I can read the code. The thing is I have yet to get to a point where 
I can sit down and start thinking code to do things.

REBOL/Core and /View has builtin  help  as well...but it can be terse

I'm looking for a set of basic essentials, of sort, that can be taught 
to a beginner so that he/she can start coding useful stuff in, say, 
3 to 5 hours.

rebol.com has some tutorials...

My skills now are: reading/understanding the code; tweaking code 
to suit my purposes. That's about it.
Read those a couple of times. I teach C++. Know a dozen more languages, 
including Prolog.

If you don't mind reading code...exploring rebol.org is good, but 
can be time consuming.
Follow the links off rebol.org Articles page
to Brett Handley's site...

To come to the point of teaching Rebol, I will have to find some 
structure in the language that permits me to extract the "basic essentials" 
in view to start students to code in a relatively short time.
ok. I will. Tks.

Enjoy...REBOL, being light, is pretty deep wide and somewhat 'hidden' 
 :)

yes, that is a problem as far as learning goes.
Like a Zen koan ;-)

Yep, very much.  But efforts are afoot to alleviate this.  If you 
know french, those books
get good reviews.

The truth is there, in some senseless sentence, but you have to self-destruct 
to get to it.
Yes, I know French. Some day soon I'll dish out the money.
Not sure they offer some "fast track" though
btiffin

I've never read them...only the reviews.  :)
