LIMBO ADMIN - blank pages PHP-Remove all Blank lines

The reason we were getting a blank page in browser after logging into the administrator page was with having some blank lines at the end of class_auth.php file in classes directory. At the end of php script ?> remove any remaining blank lines.

This problem was found in mambo configuration file as well,

http://forum.mamboserver.com/archive/index.php/t-32414.html

http://forum.mamboserver.com/showthread.php?t=9482&page=2

a diff between revision 1 and revision 3 revealed it.

In the administrator page there are two logouts, one among the toolbar and other at the right end. the logout in the right end closes the window and the logout in the toolbar goes back to the index page with user as "admin".

Limbo Update

The problem with display in Limbo was, in the config.php file we have to set the URL as https:// instead of http://
the reason being, after index.php is loaded, the requests for certain images to be displayed will be sent to pubcookie server and since Pubcookie requires authentication these requests will not be valid and gets rejected.

also in your .htaccess files you have to add

PubcookieAppID username or anyname

pubcookie application ID is used to give a common cookie name which changes with the directory path.
for more information refer http://pubcookie.org

In the registerExtAuth() function $conn->Execute("INSERT INTO #__users (name,username,email,password,registerDate) VALUES('".dbencode($username)."','".dbencode($username)."','','','$time')" );

identity providers and bookmarking

| |

[phpwiki]
Came across [a nice analysis of connetea bookmarking software|http://www.dlib.org/dlib/april05/lund/04lund.html] off a link at
del.icio.us. [Connetea|http://www.connotea.org/] seems like the right
bookmarking tool to play with
in myVocs. The [code is open|http://www.connotea.org/code] and they are
following del.icio.us ideas but
extending them in useful ways. This wouldn't elliminate del.icio.us use
but would give us a way of seemless identity integration with a
bookmarking tool.

I also took a look at the [facebook.com|http://facebook.com] site
referenced in [jim's blog|http://arch.doit.wisc.edu/jim/index.php/2005/10/04/internet2-collaboration-tools-phone-call-4-october-2005/].
This
is one of the best examples of how a [vo-core like myVocs|http://myvocs.org] should look
and work. It's got excellent methods of connecting groups to groups. It
builds excitement for the user.
Granted, this could also act as an identity provider, but could
just as easily leverage an existing idp infrastructure or be the "local
account" idp for the vo system environement.

CMS Choices

There is a plethora of CMS available, I found phpCMS, Guppy and CathDesign CMS to be ideal for our requirements,

http://www.phpcms.de/index.en.html

http://www.freeguppy.org/

http://cms.cathdesign.nl/

here is a link comparing the above three CMS

http://www.opensourcecms.com/index.php?option=com_wrapper&Itemid=139

Based on comparisons Guppy or phpCMS looks good to test (actually guppy has more security features)
but unfortunately guppy is not available in english, it is available in spanish, german, russian, italian languages !!

I will try phpCMS to begin with...

Thanks,

myVOCS usage

I have listed down some "things to be done" and my experience with myVOCS usage,

1) for a new user the first question will be " What are VO's ? how will it be useful ? " ...something which has to be made clear so that it will be used.
The link "What is this tool" is a link to yubnub, rather this can be customized explaining the concept of myVOCS (yubnub relationship) and giving some more examples.

2) Once a user gets into any VO (say cms), there should be some link to get back to myVOCS page or see the list of subscribed VO's to jump into.

3) There should be a create command on myVOCS page and a small list of created commands and a brief description of the same.

A demo of myVocs

i2fmm demo update

| | | | | | | |

the myVocs demo went well and along with Jim's work, seems to make a very nice system environment. struck again how clearly bogger.com, technocati's and del.icio.us have the potential to become the major new applications of you desktop with these technologies. amazing to see the type of system experience that can be defined with so many interfaces available. interesting trend graphs to namespace creation and management.

am working on getting the demo in an on-line followable version and will add a link when I ha
