1. Template Manager
2. Options
3. Preview Module Positions -> Disabled or Enabled

 This is another feature which took me a few years to notice in Joomla.  If you've ever installed a template for Joomla and spent hours working out where or how you are going to put what where, try adding ?tp=1 after your index.php url (ie. http://www.yourdomain.com/?tp=1)

If this doesn't work for you try this:

1. Log in to the backend of your website (into the Joomla Admin Panel)
2. Go to Extensions > Template Manager > select your template
3. Click on the big Preview button in the top right
4. Click on the link 'Show in New Window'
5. Bookmark the web address of the new window

The bookmark/favorite that you have just made can be refreshed when you change things on your site and should reflect exactly how your website is overlayed with the module positions.  You will need to repeat the process when you select a different template but otherwise the bookmark will last as long as you keep that template.

This took me a whole afternoon and involved a lot of hope as I browsed the Internet and no one seemed to have done this before.  Fortunately, MediaWiki extensions are easier to write than Joomla CMS ones :c)

This article shows you how to get your MediaWiki system to display your Camtasia Studio SWF files in it's articles.

Why Camtasia when there are other free options?

We tried lots of FLV players that were usually branded or not free.  These were awkward to configure a full screen button on the controls and do basic customization.  Our screen recorder was also not displaying the captions of the video unless it was an AVI file that we converted to FLV.  The quality was horrible.  Then we moved to Camtasia Studio where their videos were displaying in good quality but as SWF files.  This extension includes the default settings for "ExpressShow" in Camtasia Studio.

	SELECT
		p.page_id AS PageID,
		CONVERT(p.page_title USING latin1) AS PageTitle,
		CONVERT(t.old_text USING latin1) AS PageContent,
		(SELECT GROUP_CONCAT(CONVERT(wikimedia_categorylinks.cl_to USING latin1)) FROM wikimedia_categorylinks WHERE wikimedia_categorylinks.cl_from=p.page_id) AS PageCategory
	FROM
		wikimedia_page p
	LEFT JOIN wikimedia_revision r ON p.page_latest=r.rev_id
	LEFT JOIN wikimedia_text t ON r.rev_text_id=t.old_id
	WHERE
		p.page_namespace=0
		AND t.old_text=''
		AND p.page_is_redirect=0

• We have an internal wiki knowledge base using MediaWiki version 1.14.
• Some articles are available for public, some are restricted to staff and different localgroups.
• When users click on the 'Login' link, we want the system to automatically prompt them for their username/password. (Kerberos authenticated, as opposed to NTLM authenticated).
• Note: This article is displaying how to change the link and not how to setup these authentication methods.

In this particular case, I'm comparing my Live and Dev versions of the same MediaWiki site. I want to add the SQL queries I used to this article but I'm in the middle of carrying out this process and it's due in two hours.

Checking both MediaWiki have the same article content:
1. Print Special:AllPages from both sites and do an eye-check (I basically highlighted articles found in one but not the other - we had over 2000 articles... I guess I'm a bit geekly like that)
2. This doesn't show modified date and content size differences but I can run this SQL query to show me these.

 By adding the following line to your LocalSettings.php file, you will be able to log everything that WikiMedia does:

$wgDebugLogFile = '/home/username/public_html/wikidir/logfile';

IMPORTANT NOTE: The path above should be the exact full path to the wiki directory under your account.

Old Server

mysqldump -u root -p wikidb > wikidb.sql
tar -cvf wiki.tar wiki   ;this is the wiki folder on document root

New Server:

create database wikidb;  this is inside mysql, Note that both mysql versions should be same.
grant create, select, insert, update, delete, lock tables on wikidb.* to wiki@localhost identified by 'YourPassword' ;

MediaWiki Upgrade

copy all the new files to wiki folder and then run php update.php from maintenance folder after updating AdminSettings.php
