A while ago, I was facing the following error when running Facebook Command Line on my Linux:

“PHP Deprecated: Comments starting with ‘#’ are deprecated in /etc/php5/cli/conf.d/mcrypt.ini on line 1 in Unknown on line 0”

To resolve this issue, open mcrypt.ini located at /etc/php5/cli/conf.d

You will see the following code snippet:

# configuration for php MCrypt module
extension=mcrypt.so

Replace the # with ;:

; configuration for php MCrypt module
extension=mcrypt.so

Hope this helps

Firstly, download the latest Ruby Installer for Windows.

Next, install Ruby using the installer. Check the following 2 boxes during the installation:

At the same Ruby Installer download page, download Ruby development kit and install it.

By default, Ruby Installer for Windows includes RubyGems. However, it is not the latest version. Go to RubyGems download page to get the latest RubyGems.

Extract the RubyGem package. Open up Windows command prompt and navigate to the extracted directory. Enter the following command:

ruby setup.rb

To check for gem version, enter the following command in the command prompt:

gem -v

After that, enter the following command to install Ruby on Rails:

gem install rails

To check for rails version, enter the following command in the command prompt:

rails -v

Open up your Terminal and login as root by entering the following command:

sudo -s

Remove MySQL:

apt-get –purge remove mysql-server
apt-get –purge remove mysql-client
apt-get –purge remove mysql-common
 
apt-get autoremove
apt-get autoclean

Check if there are any MySQL dependencies installed:

apt-cache rdepends mysql-server
apt-cache rdepends mysql-client

Delete the preference files:

rm -rf /etc/mysql

Find all files with “mysql” and delete it:

find / -iname ‘mysql*’ -exec rm -rf {} \;

phpMyAdmin in Linux by default does not allow NO Password login.

To fix this issue, sudo open the file in /etc/phpmyadmin/config.inc.php

Uncomment the following line:

$cfg['Servers'][$i]['AllowNoPassword'] = TRUE;

Open up your terminal and login with root access:

sudo -s

Enter the following command to list all the installs of apache2:

dpkg --get-selections | grep apache2

Remove all the installs of apache2:

apt-get remove --purge apache2 XXXXXX  XXXXXX

where XXXX are the installs generated from the previous command.

To install apache2 again, you can execute the following command:

apt-get install apache2

If you encounter a 404 error when accessing localhost/phpmyadmin (after installing apache2, mysql-server, phpmyadmin), you will need to link phpMyadmin-shipped Apache configuration into Apache.

Open up your terminal and enter the following:

sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf.d/phpmyadmin.conf
sudo /etc/init.d/apache2 reload

After this is done, try accessing localhost/phpmyadmin and you should be able to login.

Ubuntu 10.04 LTS is shipped with Mozilla Firefox 3.6 by default. In order to upgrade it to Firefox 8 to support HTML5 and CSS3, we will have to add Mozilla Firefox repository.

First, open up your terminal and enter the following:

gksu add-apt-repository ppa:mozillateam/firefox-stable

Next, update the repositories:

sudo apt-get update

Lastly, install Firefox 8:

sudo apt-get install firefox
