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?

So far, i have this:

ieflat: ["Steeve" "isa" "person" "Steeve" "age" "42" "Tweety" "isa" 
"Canary"  "Tweety" "age" "75" "Chirp" "isa" "Canary"]

i1: make hash! 10 ;index subjects

i2: make hash! 10; index predicates

i3: make hash! 10; index objects

for i 1 length? ieflat 3 [either select i1 ieflat/:i [f: select i1 
ieflat/:i append f :i][append i1 ieflat/:i repend i1 reduce [to-block 
:i]]] ;am sure there is a better way of doing this...

for i 2 length? ieflat 3 [either select i2 ieflat/:i [f: select i2 
ieflat/:i append f (:i - 1)][append i2 ieflat/:i repend i2 reduce 
[to-block (:i - 1)]]]

for i 3 length? ieflat 3 [either select i3 ieflat/:i [f: select i3 
ieflat/:i append f (:i - 2)][append i3 ieflat/:i repend i3 reduce 
[to-block (:i - 2)]]]

rocket: func [s p o it][
    st: now/precise

	while[it > 0][
		s: i1/(:s)
		p: i2/(:p)
		o: i3/(:o)

		res1: intersect s p o
		it: it - 1
	]
	prin join " -> " difference now/precise st
]

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

what would be useful is to build something like a SPARQL dialect 
on top of this

anyone interested?

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!

I wouldn't bet on MAP! very much (yet?). While it's very nice concept, 
lot of functionality is missing and what's implemented is buggy. 
OTOH it's nice and pretty fast.

i'm pretty happy with hash! so far...will try map!

am still on R2
? map tells me:
map!            datatype! hash!
map?            action!   Returns TRUE for hash values.

is map! only truly availale on R3?

in R2 map! is there just for compability. map! = hash! in R2.

x: make map! [a 1 b 2]
series? x ; == true (for R2)
series? x ; == false (for R3)

ah! ok...thanks endo

Sujoy.....Link to Devcon 2007 videos.   Link is below, but you'll 
need a logon to the website. Someone else here will be able to advise 
you on that:

Couldn't find an official script for it in rebol.org though.

thanks for the link Gregg

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)

You mysql server maybe configured to accept connections only from 
127.0.0.1?

I = you

and, try to connect from a remote PC using mysql command-line tool.

If you are using Cpanel, there is a section to Grant, otherwise you 
may have to do it manually.

Or in phpMyAdmin, if you have that.

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.

% means "accept connection from any IP". It is not related to softinnov's 
mysql driver. If you use phpmyadmin or similar tool to configure 
your mysql, you should see it on GRANT options. You can find more 
info on Mysql Administration documents.

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....

try to get support for that, they can easily do that.

Arnold look for "Prvileges" tab in phpMyadmin. BTW, what type of 
control panel do you have?

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."

There is a Plesk control panel where I can create databases and add 
users/passwords (but no GRANT options) and a webadmin which is a 
PHPMyAdmin screen, that is almost identical to my self installed 
phpMyAdmin 2.6.0-pl2

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

Arnold, so you have the same set-up as I do. Plesk as the main control 
panel and phpadmin (via Plesk and self-installed). It's within phpadmin 
that I am able to grant rights to my host's IP as described above. 
Before this, I had some sites that had cPanel and I did the granting 
from there.

James, what phpmydmin version is your self installed phpmyadmin?

I need to upgrade i think.

Upgraded to 3.5, but no privileges for users tab.

Where does open-proto come from in the mysql-protocol.r in the mysql 
driver from softinnov? Word has no value in the version I am using. 
Strange. No complaints when using the script from a location on my 
webspace, trouble when used to connect from my local machine to the 
web MySQL.

I still think that it is because your mysql server does not accept 
connections except localhost.

Did you try to connect your database using mysql command-line tools? 
or MySQL Workbench from a remote PC?

What version of mySQL are you using?

MySQL 5.0.45, Protocol version 10.

Endo, possible, still I expect the open-proto to be defined somewhere.
