Deal with 4px extra pixel under image

The problem is that by default the bottom of images are lined up with the baseline of the text — which means the bottom of most letters, but there is still that small space for the bottoms of letters like p and q.

By default vertical-align is set to baseline. All you have to do to fix the problem is set:

a img { vertical-align: bottom; }

Upgrade Redmine 2.0

Step 1. Download Redmine from SVN # svn co http://redmine.rubyforge.org/svn/branches/2.0-stable redmine-2.0 Since Redmine 1.4.0, it is recommend to use Bundler to manage gem dependencies. # gem install bundler Create a symbolic link to /usr/bin # ln -s /var/lib/gems/1.8/bin/bundle /usr/bin/bundle After install Bundler gem, it is required to install a bunch of packages first: # apt-get install libmysqlclient-dev libpq-dev libmagickwand-dev libsqlite3-dev Then you can run the bundle command successfully: # bundle install --without development test

[Draft]Installing Redmine 1.3.1 on Perfect Server Debian 6 (Squeeze) ISPConfig 3

The following is my notes on installing Redmine on Perfect Server Debian 6 with ISPConfig3. If you are ISPConfig3 users and would like to install Redmine, this walk-though maybe helpful. This guide assume you have ISPConfig 3 setup already. ISPConfig is a hosting control panel, you can use it to setup web, email, MySQL database with ease. If you don't know what is ISPConfig, please find the following link: After installed your perfect server and ISPConfig, go ahead to create a client, then a website and database for the new client. Next, download Redmine, extract the archive to /var/lib/redmine, then follow the procedures below. ==Installing Ruby==

Configure firewall on Ubuntu 10.04

Just learned a command line tool ufw for configure the firewall. It seems easy to use, but the server guide didn't teach how to setup rule on specific interface.

Lucky I found the solution, to configure ufw for specific interface, use the following syntax:

sudo ufw allow in on eth0
sudo ufw deny out on eth0
sudo ufw deny in on eth0 to any from any port 80 proto tcp

Installing Ubuntu 10.04 server

I decide to setup my own LAMP environment to host my game portal. I decided to try Ubuntu, although I never have experence with it.

Fortunately, Ubuntu has large user base, it is very easy to find solutions.

After installed Ubuntu Server 10.04, I found only cli available. I prefer to have a GUI environment to get start. It is very easy to install Gnome desktop to a brand new Ubuntu server.

To add gnome desktop, simply run the following instructions.

sudo apt-get install gnome-core gdm indicator-applet-session
sudo apt-get install update-notifier
sudo apt-get install gtk2-engines
sudo apt-get install gnome-themes
sudo apt-get install gnome-network-admin

Because I run Ubuntu inside VirtualBox, I need to install the VirtualBox add-on for better performance.

Installing VirtualBox add-on require linux header and build-essential package:

sudo apt-get install build-essential linux-headers-`uname -r`
cd /media/VBOXADDITIONS_4.1.8_75467/
sudo ./VBoxLinuxAdditions.run

That's all. Next step is setup apache and mysql.
