How To Install VirtualBox 3.2 In Ubuntu

VirtualBox 3.2 was released a couple of days back, as Oracle VirtualBox 3.2, with some exciting new features. It has not yet come to the official Ubuntu repository, but you can install it from the VirtualBox Repository. Here is how to do it:

  • Open the Terminal/Konsole. (In GNOME Applications -> Accessories -> Terminal. In KDE, bring up the KRunner with ALT+F2 and type “konsole“.)
  • Open /etc/apt/sources.list for editing with the command:
sudo gedit /etc/apt/sources.list

Note: If you are in KDE, replace gedit with kate in the command above.

  • In the file source.list, add one of the following, whichever is appropriate:

For Lucid (10.04):

deb http://download.virtualbox.org/virtualbox/debian lucid non-free

For Karmic (9.10):

deb http://download.virtualbox.org/virtualbox/debian karmic non-free

Save and exit.

  • Install the GPG key with the command:
wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -
  • Now update the software source and install VirtualBox 3.2 with the commands:
sudo apt-get update && sudo apt-get install virtualbox-3.2
  • Finally install dkms with:
sudo apt-get install dkms

Calculator Application For Ubuntu Maverick Now Faster Than Chromium!

A new version of GCalctool, the default calculator application used in Ubuntu has been released. The new version (5.31.1) has some changes, most notably its speed. It is now faster than Chromium. (Yes the browser. If you do not get it, I suggest you read Jogre Castro’s blog post.)

Here is a list of the changes with GCalctool 5.31.1 :

  • New color scheme, as you have already seen from the picture above.
  • It starts really fast.
  • Keyboard input and accessibility works without any problems.

Although it is supposed to come with Maverick, you can install it from the PPA if you are using Lucid. To do it, open the terminal and execute the following commands:

sudo add-apt-repository ppa:robert-ancell/gcalctool
sudo apt-get update
sudo apt-get install gcalctool

Chromium Now Supports WebM Videos

Google has just released its VP8 video codec it acquired a few days back as WebM. This acquisition came with the acquisition of On2, which was an expert in video compression technology.

As expected, the Chromium browser on Ubuntu now supports this new video codec. To try a WebM video, you will need to install the latest daily build from the Chromium daily build PPA at launchpad. The fastest rising Opera web browser also introduced support for WebM videos recently.

The added advantage in WebM videos, as spotted by d00d @OMG!Ubuntu is that the CPU usage for WebM decoding is minimal compared to Adobe Flash. This would make it ideal for mobile devices as well. He has also provided a link for you to try out some WebM videos on YouTube.

Now that a proper video converter is out with support for WebM videos, we expect to see this video format take over the world of online videos, in the next few months.

Skype Added In Official Ubuntu Repository

Skype is finally coming in the Official Ubuntu 10.04 Partners Repository. The build process has already been finished and is awaiting approval in the NEW queue.

To install it, you have to enable the partner repository. To do this go to System -> Administration -> Synaptic Package Manager. In the Synaptic Package Manager, go to Edit -> Repositories. In the Software Sources windows, go to the tab Other Software and check http://archive.canonical.com/ubuntu lucid partner and close the window.

Then, open the Terminal and execute:

sudo apt-get update
sudo apt-get install skype

Is Arch Linux Faster Than Ubuntu? Not Really!

It is often claimed that Arch Linux is faster than Ubuntu. So, the guys over at Phoronix, decided to test if it is really true.

They put Ubuntu 10.04 against Arch Linux 2010.5 using their Phoronix Test Suite. They did a clean installation of Arch 2010.5 and Ubuntu 10.04. They also tested an Ubuntu 10.04 installation upgraded with the Maverick (10.10) packages.

They found out that both are have almost the identical performance. The only test where the performance of Arch Linux is significantly faster than Ubuntu was with the OpenGL test. However this is just because Arch Linux does not use Compiz by default when an accelerated OpenGL driver is available.

There were also some performance difference in the SQLite and Apache test. However, this is due to the different kernels that the two distros uses.

All in all, this demonstrates that Arch is somewhat faster than Ubuntu but not by much.

You can see the full test result over at Phoronix.

Sheldon Cooper: Ubuntu User

The Big Bang Theory has become my top favorite series from the time it started. The Big Bang Theory starring a group of four friends, all of whom have unusual habits has been a hit with the student and the geek culture.

The humor is something that only geeks get and that makes them feel special and exclusive.

Well, if you are a Linux fan and you have not noticed, Sheldon Cooper, the self-proclaimed genius and truest nerd on The Big Bang Theory has been seen using Ubuntu.

See for yourself in this video.

Ubuntu Is NOT replacing Firefox with Google Chrome. Its Chromium!

Word have been spreading around that Ubuntu is replacing Firefox with Google Chrome for Ubuntu Netbook Edition 10.10 Maverick Meerkat. This “news” seem to have started out with a post at ubergizmo, which TechCrunch picked up and then posted (refering to Ubuntu Netbook Edition with the no-longer-in-use name Ubuntu Netbook Remix). With Neowin too joining in with a post today, it is spreading like wildfire.

However the truth is that it is not Google Chrome which may replace Firefox; it is Chromium. (We wrote about it four days ago.)While Google has released most of the Chrome code to the Chromium Project, Chrome still has some closed-source codes and come packaged with proprietary software (Flash). Anyone with even a slight understanding of the Ubuntu Philosophy (and Licensing) would understand that Ubuntu can never have Google Chrome as a default application.

Two days ago, when this misinformation has just started spreading, Ubuntu Developer Jorge Castro wrote a blog post clarifying that it is not Chrome but Chromium that they are considering as a replacement for Firefox in UNE 10.10. Unfortunately his message did not go through. This is what he wrote:

I’d like to clarify some things about our session on default applications and Chromium.

  • Chrome and Chromium are not the same thing. Chrome is a non-free build of the Chromium project.
  • It is impossible for us to ship Google Chrome as a default web browser without compromising  our beliefs. You can read more about our licensing and how that relates  here.

I hope that clears things up, you’ll be hearing more updates in the usual development channels from the Desktop team as the cycle progresses.

Hopefully, this post in clears things up. :)

New Default Applications For Ubuntu Netbook Edition 10.10

In the UDS-M, it has been decided that there will most likely be some changes in the applications that are installed by default with Ubuntu Netbook Edition 10.10.

Here are the new applications that are being considered for UNE 10.10:

Chromium

It has been decided to have Chromium as the default web browser rather than Firefox. One of the main reasons for choosing Chromium is its speed. However, there are still some concern regarding Chromium’s non-native look and how it  will work with Global Menu. As of now the decision to include Chromium is only till Alpha 3, after which they will take the final decision regarding its inclusion.

Shotwell

F-Spot, currently the default photo management application in UNE, will most likely be Shotwell in UNE 10.10 Maverick Meerkat.

Megoo Media Player/Banshee

A lot of discussion has been going on regarding the media player for UNE 10.10. The focus is on having a Unified Media Player – one which can play both video and audio. Various applications have been looked at. However, Banshee seems to be the front runner as it already has Ubuntu One Music Store Integration and there is no disk space issue as UNE already comes with Mono.

Evolution Express

There were also discussions about the default email client. Instead of opting for a new application, it has been decided to have a version of Evolution optimized for netbook by default. Such a version of Evolution, called Evolution Express, already exist.
