sudo apt-get update
sudo apt-get install ukuu

remove ukuu:
sudo apt-get purge ukuu


Ukuu (short for Ubuntu Kernel Update Utility) makes updating your Ubuntu kernel much easier to perform. It downloads newer kernels from the internet, and changes your system to let it use them. All you really have to do is choose which kernel you’d like and reboot into it.

The kernel is basically an important piece of software found in every operating system. It acts as a mediator between the software you run every day (e.g. web browsers), and the hardware that it’s running on. Essentially, without a kernel, other programs cannot function since they can’t access your computer’s resources.

MySQL 5.5 has created a lot of hype and its not just hype, there are major performance enhancements not only in the MySQL server itself but in the newer InnoDB plugin shipped with MySQL 5.5. That’s exactly the reason why I have myself upgraded to MySQL 5.5 (The server running this blog run MySQL 5.5). Now since I haven’t come across a guide to help in upgrading to MySQL 5.5, I thought why not make one myself. So here goes nothing!

$ cd /root/ $ wget $ mv index.html mysql-5.5.8-linux2.6-i686.tar.gz

Backup the MySQL configuration

$ mkdir /root/mysql-5.1-conf $ cp -R /etc/mysql/ /root/mysql-5.1-conf

In the last few weeks we ran a poll on our site, asking our readers to point out what is Windows Vista's biggest problem. Due to the fact that our site does not have high traffic we managed the gather only 534 votes. However the results are pretty conclusive.
Our readers pointed out that, after approximately 6 months, Windows Vista has two main problems: the lack of proper drivers (36% of votes) and lots of application compatibility issues (36% of votes).

We have been using Windows Vista since it was launched and, based on our experience, we agree with our readers.

Driver problems

Since Windows Vista's launch, the drivers have been a big issue. Lots of hardware components (old and new) had no drivers for Windows Vista or, even if they had, their quality was very poor. One of the most prominent examples is Nvidia. When the GeForce 8800 graphic cards were launched, they were labeled as "Designed for Windows Vista". It is only natural that many people...
