Quick Install Memcached and Memcache for PHP on Fedora

Memcached is a high-performance, distributed memory object caching system. In web applications implementation, it is intended to alleviate database load by caching the most requested data for faster retrieval and lessen DB hits.

Installing Memcached on Fedora and adding it as a PHP module is fairly simple using the console.

Step 1: Install Memcached

yum install memcached

Step 2: Install Memcache PECL module for PHP

yum install php-pecl-memcache

Step 3: Restart Apache

service httpd restart

Step 4: Run the Memcached Daemon

service memcached start

Once finished, you should be able to access memcache-related functions and utilities. You can check the memcache entry in the phpinfo() page which verifies that it has been successfully installed as PHP module.

For more information on how to use the Memcache Class provided by the Memcache PECL module, visit the following link: http://www.php.net/manual/en/book.memcache.php

How to use 3G Phone/Modem to connect to the Internet on Fedora 11 (Linux)

Its been awhile since I attempted to connect to the internet via 3g using my phone (SGH-i550). The last time I did was several months ago with the help of wvdial. Now that there is a power outage in our area; and I forgot to install wvdial; and I just upgraded to Fedora 11, now is the perfect time to test the new features of the updated NetworkManager into action.

The following are the set of simple steps I have taken to connect to the internet using SGH-i550 via 3g on Fedora 11. I would assume that these steps will also work with other brands/models and most 3g modems around.

1. Connect 3g phone/modem to the computer


2. Right-Click on the NetworkManager Applet and select "Edit Connections"
   
   
   
   
3. Select "Mobile Broadband" tab
   
   
   
   



4. Select the 3g Device from the drop down list and click "Forward"
   
   
   
   



5. Select the Country and click "Forward"
   
   
   
   



6. Select a Provider and click "Forward"
   
   
   
   



7. Select a Plan and click "Forward"
   
   
   
   



8. Confirm the details and click "Apply"
   
   
   
   



9. Leave the preset defaults and click "Apply"
   
   
   
   



10. Close the Connection Settings Dialogue
    
    
    
    



11. Right-Click on the NetworkManager Applet again and select the newly created connection
    
    
    
    



12. The NetworkManager Applet will change its icon indicating a successful connection has been established
    
    
    
    



13. And you are done.
