We just released our first R3 based tool. See: http://www.saphirion.com/development/heat-map/


The tool gives you an editor to build hierarchical structures / layouts 
where you than can map given information criterias (Skills, Performance, 
...) into visual recognizable values (color, line width, ...).


We use this tool to visualize complex situations on one page. The 
values could be feed from a database or other source in real-time 
and the visualization will update immediatly.

Saphirion's Host-kit has been updated:
-added PNG encoder
-added Core extension module for generic additional commands
-reworked compile/build process
-fixed security flaw in Encap
-fixed bug caused non-functional networking
-improved console output handling logic
-patched ENCODE to not crash on png
-updated LOAD-GUI with currentspahirion link
-recompiled r3.exe, r3core.exe, r3encap.exe and r3ogl.exe

Update on the web-page will be available on the weekend.

Is there a new %test-demo.r3 file? The old one doesn't work anymore.

My REBOL book is going to be published in July. I've almost done 
the writing. The publisher is BroadView (in China). The first edition 
will be 10K copies. has designed the book cover, and layout some 
of the content

The book is for the people who would love to try programming and 
don't care about which language was used.

It's in Simplified Chinese. Also, The traditional Chinese edition 
will be published in this summer.

Hi! Placed my mirror game (with the slow code still) to be found 
at http://arnoldvanhofwegen.com/stuff/mirror.rebolBecause I have 
my apache thinking .r files are to be processed I renamed it to .rebol. 
Just download and rename to .r and play with REBOL/View.

is the game supposed to tell us when me make an error at some point? 
cause I can place 7 mirrors, but the end result is currently not 
valid... (it doesn't tell me which tiles aren't bouncing light at 
their counterpart)

Thank you, I found it a fun puzzle too when I found some of them 
in a summer logic puzzle book. I then found a puzzle collection with 
most of the puzzle games (Simon Tatham's portable puzzle collection) 
except this one so I built one myself using Java. One of the first 
puzzles I had to solve I solved with 6 mirrors but you have to solve 
it using 7. It was quite a puzzle to me thought I made an error somewhere 
but luckily I solved it!

No it tells you if you solved the puzzle (green) and when you solved 
it but not with all 7 mirrors.

got the yellow... almost

Those are the hardest ones! Sometimes you have to break down what 
you built up first.

I thought about that too, label font color can be set, but I was 
afraid it would slow down the app. That is why I chose to build the 
extra mirrors as a seperate layer to show on top of the grid-layer 
and the unchangeble mirror-layer.

There is a small problem. I test if the solution is found, the moment 
it is found to be not the case, evaluating stops. I can rebuild the 
working.

I can rebuild the working.
   is there a word missing there?  not sure I get it.

New version of the mirror game placed on same spot. Only on first 
screen the coloring doesn't work. See what happens if you comment 
the line before the last. Bold did not work for me either, could 
be the mac and font arial.

Hello I have a new version 1.05 'ready'. Added languages and a preferences 
panel. Only the save option to save preferences I did not fill in 
this one, because  first  of all location of this file and secondly 
I had doubts if it is needed. http://www.arnoldvanhofwegen.com/stuff/mirror.zip
It contains 3 files.

Warning: new discussion possible!

Well this was hard! 1.06 ready on zip space but because I have 0.0 
trust in Macs zippabilities I also placed all files in http://arnoldvanhofwegen.com/stuff/mirror/

The files are Windows Latin 1 format for all special characters to 
display ok, except in REBOL itself where they are a mess ):

My REBOL book has started forward sale today here http://product.dangdang.com/product.aspx?product_id=22807051
. The first 1'000 readers will get the book before the end of July.

Hello everybody: I'm working on rebol2.blogspot.com (take a look!). 
If you want to write an article on Rebol, send me an in email with 
the article and I'll publish it. If you want to see a topic discussed, 
send me an email with a request, and I'll try to write about it. 
My email is [maxint-:-tiscali-:-it]

Look also at this page: http://www.maxvessi.net/rebsite/wr/if 
 your site is about Rebol and isn't the list on the left, please 
send me your link; if you know some site about Rebol and it isn't 
in the list, please send me a link.

A new version of the mirror game is available as a zipped file at 
http://www.arnoldvanhofwegen.com/stuff/mirror.zip

This time it is version 1.07. I put a beam in. Click on a label and 
a beam will show up,right click the label or just click the box for 
a new mirror and it disappears again. (It is also becoming a showcase 
for different REBOL techniques applied, though maybe not the best 
(: ) 
Have fun with this version!

*Rebol source code is to be released very soon. However there will 
be conditions precedent to the release.

After one week of the foreward sale, 300 customers have paid for 
my REBOL book. It's not so bad. I think 1'000 is an achieveable target 
for this month. Let's consider 1'000 REBOLers coming to our camp. 
:-)

So what's this all about?!?!?  From whom does the notice about open 
source come?

I released my first game for the Android platform.

www.tree-mapper.com 	First releas of the web-page for our new product. 
Done with R3. We will add more and more over time.

I have put my example script for CGI forms with validation and refilling 
previously filled fields online on the rebol.org site. http://www.rebol.org/view-script.r?script=cgi-form-val-example.r
Maybe somebody with more (CGI security) expertise can look at it 
and comment on safety issues please.

It is far from perfect yet, the code needs a lot of cleaning up but 
I would not wait much longer for you all to have a look at my REBOL 
solution to make a small chessboard application that gives all the 
possible legal moves so you can play a game according to the rules 
of chess. You need the 2 files http://www.rebol.org/view-script.r?script=cbh.r
and http://www.rebol.org/view-script.r?script=chessmoves.rto make 
it work. 

Hope you like it and the REBOL solutions I chose to accomplish this.

Oh by the way it is NOT a chess computerprogram! It does not compute 
any best move of any kind! It just is possible to move the pieces 
playing a game according to the rules of the game.

Oh and you need the chessimages.r file I just uploaded too.

As you might know, I wrote a R3 book in Chinese, trying to attract 
more people to the REBOL camp. It sells very well so far. But I would 
like to attract more than Just Chinese. So I decide to translate 
it into English and make the English Version free. It's a slide with 
320 Pages. This slide is colorful, beautiful, and easy to understand. 
I would like you guys to help me correct my English before I put 
it to the public. I would also like this gesture to make Carl feel 
the support and love from the community.

Today I fixed one issue with the chessboard with respect to the bookkeeping 
of the kings positions. This was the last remaining piece of this 
part of the puzzle. I am curious for remarks.

Jerry, I would like to help with the English editing. Please let 
me know the next step.

Hello, I'm writing a new version of Rebolide, with color syntax higlithing, 
using another rebol script (area-tc) with perfect syntax higlithing. 
I put the new rebolide on github: https://gist.github.com/3635812
, since github works great with Rebol.

However I'm not good as you and I can't understand how make this 
new rebolide similar to the old one, see  the old one on: http://www.rebol.org/view-script.r?script=rebolide.r

My main concern at the moment is to create button to insert code 
in the main area, cut and copy works, but the functions button like 
the old one no.
May you help me?

OK, that link was just a gist,  the repository is https://github.com/angerangel/rebolide

Carl, 9-Sep-2012 15:46:54: "I need to apologize all of you for the 
lack of response to your comments. This was due to a funny incident 
that happened on my ranch.


Last week, a few heffalumps burst into my basement and turned over 
the last barrel of 1999 Châtemateloo. Unfortunately, the precious 
liquid flooded telecommunication cables and I lost network connection.

You know me, this is not a reason to give up.


Using a microwave oven, amateur radio, and 4 lines of code in REBOL 
I was able to construct a modem and here I am.


Well, I read very carefully your comments (the first two lines of 
each comment) and I noticed that most of them contain the phrase 
"Hi Carl". I was hoping that I'll find out from them what further 
steps should be taken to save the future of REBOL, but it seems that 
as usual I have to come up with a solution myself.

So, here it is.

I decided to open source REBOL.


Choice of license is very difficult because there are many kinds 
of them. I examined the majority of them, and none meets my needs. 
They are overloaded and too complicated. The only thing I can do 
in this situation is to write my own license. I name it ... Rebolense.

Creating a license is not an easy task, but is necessary.

I'll be working on it soon, so stay tuned. "

There's a growing consenus, Max, that that blog post may be better 
suited for the Humour group.

Probably a real blog post is the only way to know for sure.

Here's the Sherman REBOL compiler:

To add to the idiocy, there's now a message from the real Carl, stating 
he agrees with the fake one

Hi, I have added two scripts today on rebol.org. one is how I plan 
using the mysql driver from Nenad, the other one is reproducing the 
php script on http://www.alistapart.com/articles/succeed/to get 
well formed URL/URI 's and get rid of the ?id=99&stuff='idea' kind 
of links. 

It is not yet really finished for I haven't tested/thought about 
how this works with requesting the indexfile in subdirectories. Also 
if there are ideas how to store and reproduce articles from a database 
using one two or more keywords feel free to put them up.

A first pass at accessing the Etsy API: http://reb4.me/r/etsy


Works similarly to my Twitter API script (a few OAuth differences 
here and there). You can download it, or run it in place (do/args 
... [...Settings...]). As with Twitter, you start with etsy/as and 
go through the authorization process.  It has a few example methods, 
and an open method - etsy/api-call - that can call (as far as I can 
tell) every api function. Will try to document at some point.

Normally I do not announce my upload to rebol.org but this time is 
different. I have uploaded an upgraded version of  my interface to 
opengl: http://www.rebol.org/view-script.r?script=opengl-glu-glut-h.r
and I am asking you to insert "GLX_DOUBLEBUFFER" in the block of 
the line: "attrList-def: reduce [GLX_USE_GL GLX_RGBA  GLX_DEPTH_SIZE 
16 GLX_RED_SIZE 4 GLX_GREEN_SIZE 4 GLX_BLUE_SIZE 4 0]"  to see if 
doublebuffer works since in my virtual machine it is not working 
(an empty window is opened and no gl rendering occurs)

Not sure what to do about the lack of metadata support ...which is 
only really used when updating tables

http://comments.gmane.org/gmane.comp.db.opendbx.devel/417

dunno what the answer that Norbert gives means

I guess the odbc driver does this automatically

yes, ODBC does it. But I think it doesn't use INFORMATION_SCHEMA, 
the ODBC driver itself gets those information from db server.

Need to put this into the port abstraction then :(

Endo, ADO is a layer over ODBC. ODBC is closer to the db. People 
used ADO because it had an object-oriented API, useful for ActiveX 
languages. ODBC has a lower-level API that was more awkward for OO 
programs to use directly, so they used it through ADO.

OLEDB was sometimes as close to the db as ODBC, or was a layer over 
ODBC. Now, it's deprecated by MS, which is recommending that you 
use the faster, more standard ODBC instead.

For us, it's ODBC all the way. And we need to improve the ODBC drivers 
for REBOL.

Carl did offer us the sources but no one took him up on that

Fortunately we can improve ChristianE's R3 driver. Since I use it 
a lot at work, I need to. I'm just waiting until I have the time 
to spare, which hasn't happened in several months.

OpenDBX: Where are the REBOL drivers? The link on their site doesn't 
work.

OLEDB vs. ODBC; from Microsoft: "You are strongly encouraged to use 
one of the native OLE DB Providers

instead of the Microsoft Open Database Connectivity (ODBC) Provider. 
Native

OLE DB Providers provide better application stability and performance."

at least for it was for SQL Server. But as you said OLEDB is now 
obsolete..

Like the nchar and nvarchar types. OpenDBX converts those types to 
ASCII, then R3 would need to convert them back to Unicode.

A lot of the OpenDBX references to SQL Server don't seem to take 
SQL Server 2008 into account, so it's at least 3 versions behind 
now. Comparable to R2 I guess.

It makes a lot more sense to have OpenDBX bindings for R2 though, 
since the lack of Unicode support won't matter there.

If you knew C, then you could add the nchar, and nvchar support

Knowing C, it would be better to add it to the ODBC API, at least 
for someone who already knows SQL. That way you can get wider database 
support, since most SQL database vendors support ODBC. Heck, even 
Microsoft is making a free unixodbc driver for MSSQL.

it sets up a tcp listener but I can't find the documentation of their 
line protocol

So, Brian, want to ping Carl and ask for the ODBC sources for R2?

Wait, how would you update the R2 protocol?

make the changes, send back to Carl, he releases new version

Ah. Well, I'd prefer to make the changes to the R3 version first, 
since we can use that right away. The internal code could be backported 
to the R2 version when Carl resurfaces.

ChristianE's odbc driver for R3 is already a little more useful than 
the R2 one, but needs a bit of work. Being open source, we can do 
the work.

But if we can leverage the work for red ....

There may need to be some tweaks for Red's ports due to the different 
language model though. Don't know for sure yet.

What's missing in the R3 port documentation is best practices examples 
for different usage models. The port model is so flexible you can 
almost use it as a way to create user-defined data types, but we're 
missing complex examples of the most efficient way to use the model. 
That's another reason I wanted to make a real R3-like odbc:// scheme, 
to learn the model better.

Oh, found that announcement about the end of OLEDB: http://blogs.msdn.com/b/sqlnativeclient/archive/2011/08/29/microsoft-is-aligning-with-odbc-for-native-relational-data-access.aspx

using rebol's ODBC interface, is there a way to get the names of 
the columns in the last select query?  sometimes, we do not provide 
the columns (select * from table) , so relying on assumptions to 
match return values and their columns is quite dangerous.

another example is retrieving the db metadata.  it would be nice 
to be able to know what columns do what from the returned data directly 
instead of assuming their order (which can change from one db version 
and provider to another)

With ChristianE's R3 ODBC, the initial insert dbport returns a header 
list translated to REBOL naming conventions, though it doesn't work 
right with unlabeled columns. Not sure with R2.

If you want to get the column metadata about a table, use the 'columns 
command:
- For R2: http://www.rebol.com/docs/database.html#section-27

- For R3: http://www.diefettenjahresindvorbei.de/odbc/odbc-docs.html#section-3.8
 though there's an error in the docs, so use 'columns instead of 
'tables

ok, so what do the columns returned by the [columns]  query mean? 
 (without docs, remember I'm not assuming the docs are up to date 
or even apply to Firebirds interface)


I tried to list the RDB$FIELDS metadata table, but it clearly doesn't 
match the columns output.

The docs for what the 'columns command returns are at the link for 
the R2 docs above.

except that SQL actualy does return the column headers, its a pity 
R2's ODBC interface doesn't seem to keep/read it.

The ODBC docs are up to date. Remember, the main problem with R2's 
ODBC support is that it hasn't changed at all in 11-12 years, though 
ODBC itself has. That does mean that the docs there are up to date.

ChristianE's R3 interface returns the column headers, though that 
does need some work.

Back in 2001 I created an intranet site for a local celebrity by 
making the database tables, then having R2 use the 'columns command 
to generate column lists that were used to autogenerate the server-side 
pages for the intranet. All it took was one function call per table 
to generate the whole site. Restyling the site just meant editing 
the HTML template in the function (this was before CSS was practical).

I may find some time to tweak the R3 ODBC-API a bit if you could 
supply a prioritized list of things that need work. Regarding problems 
with certain SQL types one easy workaround could be to just allow 
all types without direct support by rebol to read them as strings, 
you then could do anything you like withthem. Regarding "R3's documentation 
for its port model is a bit lacking" - I surely won't have any time 
to find out why the port model I used feels alien to R3 without the 
better R3 beeing documented anywhere.

We weren't requesting an update of the port model to you, Christian. 
That can wait until we have a better idea of what it should be.

Here is the code I use to load your ODBC extension, which patches 
it after load:

; Load and patch the ODBC extension
odbc: import/no-user %odbc.dll
unless 'case = pick body-of :system/schemes/odbc/actor/open 10 [

system/schemes/odbc/actor/open: func [port [port!] /local result] 
bind [
	port/state: context [access: 'write commit: 'auto] 

 result: open-connection port/locals: make database-prototype [] case 
 [
		string? select port/spec 'host [ajoin ["dsn=" port/spec/host]]
		string? select port/spec 'target [port/spec/target]
		'else [cause-error 'access 'invalid-spec port/spec]
	]

 all [block? result lit-word? first result apply :cause-error result] 
	port
] odbc
]

There was a bug in open with certain kinds of odbc port specs. The 
above code fixes that.

You can't do an R2-style hot-patch of a function in R3, but you can 
replace the entire function with a new, fixed one.

I'm interested in creating a rebol associative db. Terry, I know, 
was talking about one such back in May last year (i think he called 
it rocketdb) - but apart from the altme logs and something on a redis 
google group, i cannot find anything. Does anyone know whether he 
released something or how i could contact him?

...this needs correction of course, to handle s p o combinations, 
but the basic idea is exactly as Terry had worked out

An associative database would be fun to have in REBOL. The 'map data 
structure in R3 replaces 'hash, and is supposed to be better.

There have been some linkups between REBOL and the relavance associative 
database, but nothing much has come of it.

Thanks Sunanda - have seen those... have not been able to find the 
video of Ron Everett's talk though. Would be good to see it - would 
you happen to have a link?

I think this would be the start of something superb. If we can build 
a SPARQL like query interface on top of an associative db in rebol, 
we could simply point it to any of the open data initiatives and 
then go on the ride of a lifetime!

need a logon to the website. Someone else here will be able to advise

I want to change some data in a mysql database from a REBOL (2) program 
using DocKimbel's mysql-portocol.r When I use a .r script from my 
website I can connect to the database. I figured that when I ran 
a script from a console I would be able to quickly test my script 
but somehow I am stopped because the script cannot connect. This 
is the error:
** Access Error: Cannot connect to mysql-01.yourname.nl
** Where: open-proto
** Near:
Any ideas?

Arnold, make sure you GRANT privileges to the mysql user before I 
could see it remotely. Make sure you use the '%' parameter or you 
won't see past the localhost. See mysql reference manual for help. 
Also make sure you open the port (3306)

I have the database on my host/provider's site, maybe that is only 
accepting requests by scripts on it's own local address. Could be.

The % parameter? I have http://softinnov.org/rebol/mysql-usage.html#sect12.
for my documentation.

Arnold, I just know enough to get myself connected so these instructions 
might not be too good. As Endo and I are suggesting, perhaps you 
can only accept connections from 127.0.0.1 (localhost). So, you have 
to Grant privileges to the user from your IP. 

Go to http://whatismyipaddress.comand then click on "IP details." 
You will find "Hostname." It is that hostname that you will grant 
privileges to along with the user such as  [user'-:-'hostname]. I imagine 
right now it only accepts [user'-:-'localhost]

I guess my hosting provider is not supporting the GRANT options in 
database user screens and their supplied phpmyadmin. I think I have 
a trick on my sleeve though with a self installed phpmyadmin. No. 
More luck maybe tomorrow....

Hi I found something in the config.inc.php  file and documentation 
that says "$cfg['Servers'][$i]['AllowDeny']['order'] string
If your rule order is empty, then IP authorization is disabled."

Most of the time the support of my provider is really good, I'll 
ask them too.
