Official release of this feature will be rolling out in the next few days, but if you cannot wait and you are concern about your Dropbox security as I do, here are the steps to enable two-step verification beta.

In some of my sites, I don't want to include Submitted by in each post. Going to content type admin settings, I can disable that line entire line including the timestamp of posting, but that is not my requirement. I only want the author information to be remove or to hide.

Here's how I solve this case:

Edit node.module under modules/node directory. In Drupal 7.15, the section that you need to edit is in line 1469
vi +1469 node.module

In some odd cases like you are troubleshooting network problem or you want to join temporarily a different VLAN or subnet, it is very handy, useful and sometimes really required to change your Ubuntu box IP Address.

Use ifconfig
sudo Ifconfig eth0 192.168.1.88 netmask 255.255.255.0

Add route
sudo route add default gw 192.168.1.254

Where:192.168.1.88 is the IP Address that you want to use.
255.255.255.0 is the subnet mask of the network you want to join
192.168.1.254 is your gateway

Every time I setup a new Ubuntu LAMP (Linux Apache MySQL PHP) Server, I usually install this way:

SSH
sudo apt-get install ssh
Apache2
sudo apt-get install apache2
PHP5
sudo apt-get install php5 libapache2-mod-php5
MySQL Server
sudo apt-get install mysql-server
phpMyAdmin
sudo apt-get install phpmyadmin

This guide is updated and tested to the latest Ubuntu and Linux Mint.

Two ways:

Double the font to open the font preview and select “Install”.
Go to Control Panel --> Appearance and Personalization --> Font.
Then drag the font file and drop it to the Font Control Panel window.

After you identified the interface you want to change, edit the network configuration file:
vi /etc/sysconfig/network-scripts/ifcfg-eth0 if it is eth0;
vi /etc/sysconfig/network-scripts/ifcfg-eth1 if it is eth1.

ifconfig -a | grep eth

Ubuntu 10.10 'Maverick Meerkat' just officially released; with some requests I received today how to upgrade their old server - this is for you guys:

Install update-manager-core:
sudo apt-get install update-manager-core
Edit /etc/update-manager/release-upgrades and set Prompt=normal
Launch the upgrade tool:
sudo do-release-upgrade
Just follow carefully the on-screen instructions.

Using update manager:

sudo apt-get install update-manager

Or simply this:
