I was looking for a solution to share some of my files in my Ubuntu server to others and while thinking of “cloud computing” at that time, I am thinking if i can try to share my files by linking my box to my existing dropbox account or not. Thus, i give a try and it seem it works. Here are the steps how to do it.
Step 1. Download and extract the dropbox client
Step 2. Extract the file
Step 3. Run the dropbox client deamon wiht the following command:
Step 4. Since the server is not link to any dropbox account yet, so you will see the following message keep showing every few second:
This client is not linked to any account…
Please visit https://www.dropbox.com/cli_link?host_id=ed2986f99681f0a7b0bf1cd36c79d3e9&cl=en_US to link this machine.
This client is not linked to any account…
Please visit https://www.dropbox.com/cli_link?host_id=ed2986f99681f0a7b0bf1cd36c79d3e9&cl=en_US to link this machine.
Step 5. You may now copy & paste the link to any browser by using any computer so that it will start to link this machine to your dropbox account. You will be asking to provide your username & password in order to link this to your dropbox account.
Step 6. Once it’s successful, you will see the the following message in your Ubuntu linux machine:
Step 7. Now you may press CTRL + C to terminate the deamon process now.
Step 8. You can manually start the service by running the following command:
Step 9. You may start to snyc and copy any file to your dropbox folder now.

The Ubuntu team is very pleased to announce the release of Ubuntu 12.04 LTS (Long-Term Support) for Desktop, Server, Cloud, and Core products.
Codenamed “Precise Pangolin”, 12.04 continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing a few new features and improving quality control.
To be a bit more precise about what we’re releasing today…
There are 54 product images and 2 cloud images being shipped with this 12.04 LTS release, with translations available in 41 languages. The Ubuntu project’s 12.04 archive currently has 39,226 binary packages in it, built from 19,179 source packages, so lots of good starting points for your imagination!
For PC users, Ubuntu 12.04 supports laptops, desktops, and netbooks with a unified look and feel based on an updated version of the desktop shell called “Unity”, which introduces “Head-Up Display” search capabilities.
Finding and installing software using the Ubuntu Software Centre is now easier thanks to improvements in speed, search and usability.
Ubuntu Server 12.04 has made it much easier to provision, deploy, host, manage, and orchestrate enterprise data centre infrastructure services with the introduction of new technologies such as “Metal as a Service” (MAAS), the Juju Charm Store, and the latest OpenStack version, codenamed Essex. These technologies further position Ubuntu Server as the best OS for scale-out computing.
Read more about the new features of Ubuntu 12.04 in the following press releases:
Long term support maintenance updates will be provided for Ubuntu 12.04 for five years, through April 2017. For those working on the ARM architecture, an 18 month supported release is also provided for the ARM server using the ARM Hard Float (HF) architecture.
Thanks to the efforts of the global translation community, Ubuntu is now available in 41 languages. For a list of available languages and detailed translation statistics for these and other languages, see:

GIMP 2.8 RC1 was released on April 8, 2012. The details of this new release are on the official site. Here in this article I’ll show how to install GIMP 2.8 on Ubuntu 12.04.

and you’re done. GIMP 2.8 RC1 has been successfully installed on your Ubuntu 12.04.
Now you can install Ubuntu on your Android phone. Canonical has announced Ubuntu for Android which will provide a full Ubuntu desktop experience on the Android phones. It will work in the same way it works on your PC. Your Android phone will work same as other Android phones but when you connect it to a dock with a monitor, you can see the Ubuntu desktop on the attached monitor.
The user interface is same (Unity) and several free applications are available to access easily. The important thing and the main feature is the consistency of data and other services between Ubuntu and Android environments which includes unified contacts, messages and call through the desktop, synchronized calendars and social media integration.
Since both operating systems share the same kernel so there will be no such issues like “an Ubuntu application running atop Android or vice versa”. Both applications will run at the same time on the same device which gives a great performance.
Mark Shuttleworth said:
The desktop is the killer-app for quad-core phones in 2012. Ubuntu for Android transforms your high-end phone into your productive desktop, whenever you need it.
He also said that they are aiming about 200 Million Users in 4 years.
If you want to install Ubuntu on your Android phone then your Android must have at least 1 GHz processor, dual-core CPU, 2 GB free space, shared kernel driver, X driver, HDMI support and 2 GB RAM.
VLC is an open-source media player whose latest version VLC 2.0 was released some days ago.

Ubuntu 12.04 LTS (Precise Pangolin) is going to be the next long term support release after Ubuntu 10.04. Its final release is scheduled on April 26th.
Ubuntu 12.04 LTS (Precise Pangolin) is going to be the next LTS (Long Term Support) release after the version 10.04. The previous LTS releases were supported for 3 years for the desktop version and 5 years for the server version but Ubuntu 12.04 will be supported for 5 years on both desktop and server version.
On February 16th of this month Ubuntu development team hit Feature Freeze. Feature Freeze is a point where the developers stop introducing new features, packages, APIs. From this point they start concentrating on fixing bugs in the development release to solidify the included features and making the development release more stable and secure.
At the Ubuntu Developer Summit in November 2011 Canonical announced that the default download for Ubuntu 12.04 will be 64-bit (32-bit version will also be available as a user choice though).
Note: The Ubuntu 12.04 ISO image size is 750 MB, that means it cannot be burned on a CD (which can carry only 700 MB) hence you will have to go for either a DVD or USB drive.
1. Much faster start up time for Ubuntu Software Center
2. Refinements in Unity
3. Replacement of Banshee with Rhythmbox
4. Tomboy note-taking application will be removed
5. Mono framework will also be removed
6. HUD feature
The main feature of Ubuntu 12.04 will be the HUD (Head-Up Display). By this HUD feature application menu items can be accessed right from your keyboard, without the need for using the mouse (hotkey searching).
Adding to the HUD feature Shuttleworth said:
HUD will ultimately replace menus in Unity applications but for Ubuntu 12.04 at least the menus will remain.
MyUnity is an independent configurator for Unity, a small system utility for Ubuntu, that can handle the customization of the Unity Launcher, Dash and Panel. Canonical accepted the MyUnity project in their default software repositories and it will be available to all users starting with the Ubuntu 12.04 LTS (Precise Pangolin).
Mark Shuttleworth announced on 31 October 2011 that by Ubuntu 14.04, Ubuntu will support smartphones, tablets, TVs and smart screens. Yay!
Ubuntu 12.04 LTS (Precise Pangolin) released! (This section of the article was updated on April 26, 2012)
CentOS and Ubuntu both are Linux distros. Below are some major differences between them.
1. CentOS is based on RHEL (Red Hat Enterprise Linux), while Ubuntu has its roots in Debian.
2. On an Ubuntu system the root password is randomly generated which is not known to the administrator. You will have to use ‘sudo command’ to get root-privileges.
3. Repositories of Ubuntu contain fresher packages than CentOS, it tends to be less conservative than CentOS, whereas CentOS packages focuses only on security patches.
4. CentOS uses YUM package manager with RPM packages whereas Ubuntu uses apt with DEB packages.
5. Ubuntu cleanly upgrades between major versions, CentOS is not so good to do that (needs a reinstall often). [via: Liz Quilty]
Know some more differences? Please put them in the comment box, I will add them in the post.

When the dash starts, the focus is on search box. When search results are in, arrow keys can be used to do usual and Enter launches the choice. It also has its own version of “I’m feeling lucky”. When the search is still going on, tapping Enter twice will invoke the first search result.
To open application lens: Super + A

Recently Linux Mint’s developer team released Cinnamon for Linux Mint 13 which is the new desktop environment, it follows the layout of traditional desktops. If you want to try out Cinnamon but you don’t have Linux Mint installed on your system and you are using Ubuntu instead, then you can use the method given below to install it on your Ubuntu machine.
Cinnamon is available in a PPA (personal package archive) for Ubuntu. First of all open the terminal and run the following command:
Press Enter when it prompts you. After that update the available packages list by running the command given below:
Now you can install Cinnamon with this command:
Press Y and Enter when it prompts you.
If you are not using Ubuntu then you can go to Cinnamon’s official page to find instructions on how to install cinnamon on your distribution.
Installing Cinnamon will not replace your default Ubuntu desktop environment. It will just add an option of Cinnamon at your login screen. To enable Cinnamon log out from your current session and from the login screen select Cinnamon and log back in.
What you see now is Cinnamon. Start playing with it and check out its features.
If autologin is enabled in your system then every time the system gets rebooted it will come up with unity by default, then you will have to logout each time you want to switch back to Cinnamon. It will be better to make Cinnamon your default desktop environment, here’s how to do that.
You will see Ubuntu’s global menu bar is still there (at the top of the screen). If you want to remove it then run the command given below, log out and log back in:
If you want to get it back then use the same command by replacing “remove” with “install”
