First you need youtube-dl tool or ‘cclive’ to download the Youtube .FLV file.
Then, download the Youtube stream.
python youtube-dl http://www.youtube.com/watch?v=lee7a55401e
Alternatively, you can use ‘cclive’ to download the youtube stream.
cclive http://www.youtube.com/watch?v=lee7a55401e
After that, use ffmpeg to extract the audio and encode it to MP3
ffmpeg -i lee7a55401e.flv vn -acodec libmp3lame -ab 128000 -ar 44100 lee7a55401e.mp3
Note: You need to install the restricted codecs in order to extract MP3 audio files.

RouterPasswords.com is a website that list a collection of default router passwords from popular vendor.
This is handy should you lose the instruction manual or forgotten the default password.
MySQL service port are not meant to be accessible to the outside world as it would become a security concern to the administrator.
Although MySQL server (mysqld) by itself has a built-in mechanism to deny access from unauthorized ip-address, it still does not protect it from being overwhelmed by multiple malicious requests or buffer overflow attack directed to the server.
One of the solution is to limit the MySQL port access to trusted network using iptables
This assume your trusted network has the address within the range of 192.168.1.1-192.168.1.254
iptables -A INPUT -i eth0 -p tcp -s 192.168.1.0/24 --dport 3306 -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -o eth0 -p tcp --sport 3306 -m state --state ESTABLISHED -j ACCEPT
MySQL server (mysqld) uses port 3306.
Note: Always assume the internet as the untrusted network!
The upcoming Ubuntu 11.10 release (Oneiric Ocelot) will drop Synaptic Package Manager from default installation in favor of Ubuntu Software Center.
This has been foreseen since Canonical has spend their effort in developing and improving Ubuntu Software Center as a convenience one-stop center to install free and paid software alike.
Personal Thoughts
Personally, I still prefer to use Synaptic Package Manager over Ubuntu Software Center as it is still doesn’t offer the same number of options that I used to get from Synaptic (ability to search by name, description, ability to test the fastest mirror).
But I believe the changes that Canonical and Ubuntu community made might make it easier to streamline the looks and functionality of package manager into desktop environment (Unity) regardless of the computing platform.
sudo is probably the most used command in Ubuntu.
In this post, I will show you how to make ‘sudo’ display funny and humorous error messages in Ubuntu Linux.
To do that, you would only need to edit the /etc/sudoers :
sudo nano /etc/sudoers
Then find the line that starts with Defaults env_reset, add insults at the end of the line so it would look like this:
# See the man page for details on how to write a sudoers file
#
Defaults env_reset, insults
Save the file, and you are done! You can test the results by running the sudo command and entering the wrong password.
