On 10.6.x you do the following:

1. Setup your base level domain in Server Admin (usually www)
2. Open Applications > Utilities > Terminal
3. Type – cd /var/named/zones
4. This get you to the folder with DNS configuration files
5. Type – ls -al
6. Find the db file that is similar to your domain (i.e. db.my.website.zone.apple)
7. Open the file in a text editor by typing – nano db.my.website.zone.apple (use your file name)
8. Ctrl-V (or scroll) to the bottom of the document
9. Add wildcard entry by typing – * IN CNAME website.com.
10. Close the document with Ctrl-x and then type – y to save.
11. Go back to Server Admin and restart the DNS service.
12. * should now appear.

If you are running a network it is easy enough to force a function across the site by dropping a script in the mu-plugins folder.

Basically, I grabbed the code from http://netweblogic.com/other/adding-removing-allowed-filetypes-wordpress-media-library/ . I added all of the default MIME types and then added the additional ones I needed at the bottom (Notebook by Smart).

Drop the file in the mu-plugins folder, add the MIME types to your whitelist in the Network>Settings, and test with an upload of the appropriate file type.

The nice thing is that you can add new MIME types with out hacking core or limiting it to an individual blog template.

Here is the file that I used in my install.

It just keeps getting better!

To accomplish this task we are going to need to learn about a few things:

1. Server Virtualization
2. DNS basics
3. Linux LAMP
4. WordPress and Buddypress

Server Virtualization

Basically virtualization is software/hardware that allows you to run a complete operating system on an existing machine as through it is a different physical machine. This allows a systems resources to be maximized and for an end user to interact with an operating system independent of the underlying hardware.

We are going to use Virtualbox by Oracle an open-source virtualization tool for this session. It is quit easy and can be used on Windows, OS X, and just about any variety of Linux.

1. Install following the directions in the user manual.
2. Configure Example VM settings
   1. Copy Example.VDI folder to your VMMachine Directory
   2. Adjust VM settings to suit your machine
   3. Start it up.

VM Setup after install:

1. Update Current Modules
   sudo apt-get update
2. Upgrade your server to latest software and patches
   sudo apt-get upgrade
3. Install openSSH server so that you can use a terminal to control server
   sudo apt-get install openssh-server
4. Open terminal session your platform of choice and ssh into the box
   ssh bpadmin@<your-ip-address>
   (You’ll be prompted to add the RSA Key, type “yes” and then input your password.)
5. Setup Webmin on your server using APT repositories
   1. Add Webmin APT repository to server APT sources
      sudo nano /etc/apt/sources.list
   2. Add Comment and Webmin URLs
      ##Webmin Repositories for web-based server administration
deb http://download.webmin.com/download/repository sarge contrib
deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib
   3. Fetch and install my GPG key with which the repository is signed
      cd /root
wget http://www.webmin.com/jcameron-key.asc
sudo apt-key add jcameron-key.asc
   4. Update your repositories and install webmin
      sudo apt-get update
sudo apt-get install webmin
   5. Test your webmin install by navigating to https://<your-ip-address>:10000
   6. Your get an untrusted certificate warning (This is normal unless you purchased a 3rd party certificate, which is totally unnecessary.)
   7. Accept it.
   8. Login using admin user info.
6. Configure local DNS using Hosts file
   1. Server DNS
      1. Set up an entry for host server in the /etc/hosts file
         sudo nano /etc/hosts
      2. Add line with server reference to end
         <your-ip-address> buddypress
      3. Check your DNS by pinging your URL, it should have the IP in the response.
      4. Save
   2. Client DNS
      1. Setup an entry on your client machine, this various depending on the flavor of your OS.
      2. Check your DNS by pinging your URL, it should have the same IP as the server
7. Begin our LAMP (Linux, Apache, MSQL, and PHP) server setup (Adapted from HowtoForge.com)
   1. Install MySQL database server
      sudo apt-get install mysql-server mysql-client 
      1. Set up a strong root password
      2. Check MySQL in command-line
         mysql -u root -p
         (enter password)
      3. We’ll check the status of the server with a sql command (the semi-colon is critical)
         show status;
      4. Exit MySQL Shell
         exit;
   2. Install Apache2 server
      sudo apt-get install apache2 
      1. Open your web-browser and check your apache server at both IP address and buddypress URL. Both should work.
      2. Configure apache2 settings and modules in webmin
         1. Log into Webmin @ https://<server-ip-address>:10000
         2. Click Servers
         3. Click Apache Webserver
         4. Click Global Configuration Tab
         5. Click Configure Apache Modules icon
         6. Make sure rewrite is enabled and save
         7. Stop and start the apache server using the hyperlink in the top right corner
   3. Install PHP5 to use with Apache2
      sudo apt-get install php-5 php5-suhosin 
      1. Restart Apache
         sudo /etc/init.d/apache2 restart
      2. Create a phpinfo file to verify PHP settings
         1. sudo nano /var/www/info.php
         2. Add the phpinfo function to file
            <?php phpinfo(); ?>
         3. Save
      3. In your web-browser navigate to http://<your-ip-address>/info.php
      4. Verify PHP settings.
   4. Add additional useful PHP extensions
      sudo apt-get install php5-mysql php5-gd php5-imagick php5-curl
   5. Your webserver is now ready to rock!

Setting Up WordPress with SVN

1. Install SVN client for linux
   sudo apt-get install subversion
2. Change to web directory
   cd /var/www
3. Use the guide provided by WordPress.org
   sudo svn co http://core.svn.wordpress.org/tags/3.1 .
   
4. Now prepare a database for wordpress install using Webmin

Looking at plans to create a national digital library:

With the Internet and e-readers, the question might arise “Why do we even need a digital public library?” David Rothman, founder of TeleRead and long-time proponent of such a project, makes the case ably in a November essay in The Atlantic.

“Knowledge is the common property of mankind.” Thomas Jefferson
“(T)here is one thing I currently cannot do with my Kindle despite all the sizzle in the commercials–read public library books. Local libraries do not use the Kindle format for their electronic collections, relying instead on rival standards used by Sony Readers and certain other devices.”

Love the ending quote. As an educator I can relate, but I think about teachers. To many believe information is expertise, and knowledge is wisdom.

A professor of mine once complained about his latest crop of students. “There has never been a generation more capable of finding data nor less capable of understanding it.” Whether that’s true or not this is: Books provide the context for making sense of data. A digital public library would extend the reading of books to most people in all places in the U.S

I can’t wait to get a test server setup and report back.

Check out the video:

Why are public schools in the U.S.–especially in Texas, where we are facing $18-$20 billion dollar deficit with at least 10% cuts to education funding–persisting in buying expensive licensing for tools like MS Office when OpenOffice, Googleapps for Education are available at no recurring license fee or initial entry point? The support costs (e.g. training) are less expensive over the long-haul than the old tools.

The reason is simply that our comfort level as educators, as technology support is for the old, expensive tools that give us the illusion of “the best.” It’s time we re-defined what we consider the best tools for education and learn the tools that are most available to our students.

I totally agree with the second paragraph. There is such an odd imbalance to most districts IT. Some how we’ve got to bring the focus back to what we are doing with the tool, not that we have the coolest fanciest tool.

I think the tools are something that is easy to achieve, you just need money. An institution that is actually creating critically thinking and collaborating students is a rarity.

Originally, we looked into using Elgg. However, we have been using WordPress for the last few years with great results.

Buddypress was a natural choice to explore.

The ingredients consist of:

• WordPress 3.0 install
• Directions on creating a multi-site WP3.0 install
• Add LDAP integration so that you can control (It is a bit buggy but works good enough.)
• Install BuddyPress
• Use the following plugins to dial-in the install:
  • BP Group Management (Allows you to manage Groups from backend.)
  • Profile Redirect (Automatically redirects users to their profile at login.)
  • BP Like (Similar to Facebook liking.)
  • Restrict Group Creation (Allows admin to restrict who can create groups and prevents students from creating private or hidden groups)
  • Disable User Gravatar (Prevents a students outside gravatar from being pulled into the school install.)
  • BuddyPress Moderation (Allows students to report or flag inappropriate content, posts, or members.)
    (These plugins can be installed from with in WordPress)

We’ll see how it goes….

In the mean time I’m hoping that a release version of the Album+ and Group Documents plugin will be released soon.

I realized that it would be easy enough to edit the file that creates new accounts to automatically insert an email address if the new email field is blank.

1. Navigate to <moodle_root>/lib/moodlelib.php

2. Edit the file by adding the logic below:

/**Removed (not) from line below and commented out text to automatically create a valid email address**/
 if (empty($newuser->email)) {
 /*if (email_is_not_allowed($newuser->email)) {
 unset($newuser->email);
 }*/
 //This automatically creates email address based upon your domain.
 $newuser->email = $username . "@your.domain";
 }

3. Now when users login and don’t have email, they are automatically assigned an email. This same trick can be used if your students don’t have true email accounts.

I can’t remember which line you begin editing but you can find it by searching for “if (!empty($newuser->email)) {“.
