Simple solution to Fast duplicate key press problem on keyboard in Ubuntu10.10


In my Ubuntu10.10 suddenly got some problem. The problem is that —

When i was pressing duplicate key very fast then it accepts only the fast key and escape the other duplicate keys. Such as if i type “http://” then it write “htp:/”, “teen” becomes “ten” etc.

To solve this problem go to

System->Preferences->Keybord
Then go to “accessibility” tab and uncheck the “Ignore fast duplicate keypresses” under “Bounce Keys” section.

Simple steps to setting up virtual host host on Ubuntu Server


Virtual host is a virtual environment over the top of your current web server to simulate a separate hosting environment. Using virtual host you can enable site specific features and keep your development environment totally separate from another one.

For tutorial you need to mod_rewrite enabled.

Step 1: setup hosts file

open /etc/hosts and add a virtual domain with a specific local IP.

Lets assume that our virtual domain name is “ruzdi.com” and It will listen to the ip “127.0.0.2″

so on /etc/hosts file we will add

127.0.0.2 ruzdi.com

now whenever you browse http://ruzdi.com your browser will actually hit http://127.0.0.2

Step2: configure virtual host with apache
Now goto /etc/apache2/sites-available and create a file named “ruzdi.com

sudo touch ruzdi
sudo gedit /etc/apache2/sites-available/ruzdi

write the following contents inside. but please note to create the appropriate directory before linking your virtual host with that, for example we’ve create a folder named “/var/opt/ruzdi” and linked that directory as my document root in the following configuration file.



<VirtualHost 127.0.0.2:80>
        ServerName  ruzdi.com
        ServerAlias  ruzdi.com
        ServerAdmin admin@ruzdi.com
        DocumentRoot /opt/ruzdi
        <Directory /opt/ruzdi/>
                Options FollowSymLinks
                AllowOverride All
        </Directory>

</VirtualHost>

now create a symbolic link of this file to /etc/apache2/sites-enabled directory as “ruzdi.com

sudo ln -s /etc/apache2/sites-available/ruzdi /etc/apache2/sites-enabled/ruzdi

**** here look directory location is /opt/ruzdi so you must create a directory named “ruzdi” on /opt location

Step 3: restart apache

simple, either one of the followings

sudo a2ensite ruzdi

And

sudo /etc/init.d/apache2 restart

now on your browser to http:// ruzdi.com

***This is post is similar Hasin Hyder blog post I just change a little. In my case on the hosts file port was not working so I removed it and I got everything all right.

Setting up zend framework on ubuntu server


Now i am going to install the Zend Framework. Download the most recent version from the Zend Framework website and extract it to the /opt folder.

To enable us to easily switch out different versions, we will create a symbolic link to this folder (just right click and select the ‘Make link’ option and name it ‘zend’ and place it to your favourite location in my case I placed it to /var/www/ )

Next, we will tell php to include the zend framework in the include_path.


sudo gedit /etc/php5/apache2/php.ini

Add/Change the include_path in to :


include_path = ".:/var/www/zend/library"

Note that I used the symbolic link in the include path.. This way, when there is a new version of ZF, we can just switch out the symlink without having to edit the ini file!

In order to use the zend framework command line tool (/var/www/zend/bin/zf.sh), we need to install the php command line interface (php5-cli).


sudo apt-get install php5-cli

Note that the CLI uses a different version of the php.ini file (NOT the one in the apache2 folder but in the cli folder!). We need to tell CLI also where the zend framework directory is located.


sudo gedit /etc/php5/cli/php.ini

and set:


include_path = ".:/var/www/zend/library"

The final step is to include the path to /opt/Zend/bin in the unix PATH variable (this way, you can use zf.sh instead of /var/www/ zend/bin/zf.sh). use the following command .

sudo gedit ~/.bashrc

Add the following line at the end:


PATH=/var/www/zend/bin:”${PATH}”

The Zend Framework relies on the apache “rewrite” module. So, go ahead and enable the “rewrite” module using the following command:


sudo a2enmod rewrite

Restart apache..


sudo /etc/init.d/apache2 restart

and you should be all set
