Subscribed to Linux Hater’s Blog : Funny and hillarious blog

After discovering Linux Hater’s blog from Google Reader and Technorati, I decided to subscribe it as it was a funny and hillarious blog. It make fun of people who are using Linux for the wrong reasons (such as trying to act cool) and how some things in Linux are not better than any other operating system.

Other than that, it contains criticism of the Linux community in general, mainly directed towards fanboys and developers, although one can easily surmise that the author himself is a Linux user who has experience in writing applications, and presumably using a Debian-derived Linux distro.

Well I might be wrong, but Linux Haters Blog is a must read if you are a Linux user yourself because it offer insights of the overall of how GNU/Linux operating system compare to other OS and what would make Linux a better OS

Enable Network Printer Sharing with Ubuntu Linux computers

Having a shared printer within a computer network is a nice thing to have. Since all computers within the network can access a remote printer to print documents. Maintenance cost is much more cheaper and easier since you only need to service only a single printer within a network.

Here’s how to enable Printer sharing with Ubuntu (or other Linux based computers) through GNOME :

At the computer with the printer

Administer Printers Ubuntu
  • First at the Desktop, go to System->Administration->Printing. A dialog will appear
  • Go to Server Settings, and check the “Share published printers connected to this system” checkbox

    Administer Printers Ubuntu

  • You may, optionally select “Allow users to cancel any job”
  • Click Apply, and close the dialog

At the client computer(s)

Network Printer Sharing Ubuntu, using Samba

  • From the Desktop, go to System->Administration->Printing. A dialog will appear
  • Check “Show shared printers from other systems” checkbox. Click Apply
  • Repeat the first step, this time click “Refresh Printer Queues” button. You shall see the list of shared printer from the server computer
  • Repeat this on other computers on the network to share the printer

That is all to it! Now you can print documents across your computer network.

How to Synchronize Current Time in Ubuntu

As some of you might aware, the time kept by computers (or other timepieces such as clocks) are not accurate as there are various factor that causes time drift. Quartz inaccuracy, temperature, quality of the equipment, power from battery, mechanical wear and tear and so on.

These minor drift while might not seems to be significant, it will give you inaccurate measure of time. This might affect your other productivity work as the time kept by your computer is not accurate to the last second. Plus, certain application such as Stellarium and GPredict depends heavily on the time kept on your computer to give accurate result.

How to get accurate time in Ubuntu
You can ensure your computer gets the most accurate time by synchronizing it with an NTP server .

To do this you need to right click the Tray Clock in Ubuntu, and selects “Adjust Date & Time”.

Adjust Date and Time

A dialog will appear, press “Unlock” and enter your Administrator password to enable the menus.

Adjust Date and Time

Answer “yes” to install NTP packages. If your computer is connected to the internet it will be automatically synchronized with an NTP server.

Bonus :You can select the nearest NTP server to your place for faster synchronization, as shown on the picture. The nearest NTP server to Malaysia is maintained by SIRIM – mst.sirim.my.

NTP Time Servers in Ubuntu

Synchronize Time using command-line
Alternatively you can synchronize time by using ntpdate command-line tool, which is covered previously in this blog.

Ubuntu Release, Maintenance and Support Schedule

Mark Shuttleworth has written a good blog post detailing about future Ubuntu release schedule and the length of support for a particular release, whether its a standard release or an LTS (Long Term Support) release.

In his post, he also explains about the point release concept for the LTS, which each Long Term support installation will receive continuous updates up until the next release of LTS. Which is due to be released in two years time. This point release will allow fresh LTS installation to receives new patches and updates without going through the hassle downloading them through the internet.

Standard releases will continue to receive patches and updates for one and a half-year and Server LTS release will continue to receive updates for 5 years.
