Ubuntu is all set to go Mobile: Ubuntu for android

This time ubuntu stunned the mobile world by announcing a future concept of carrying a desktop within your very smart android phone.

A full Ubuntu desktop, on your docked Android phone thats what ubuntu desktop for android. which means ubuntu is ready to launch their solution for android phones, which enables a powerful android phone a desktop when docked. a keyboard and mouse duo can also be associated with this andro ubuntu desktop. why  carry two devices when you can do it all with your dual core android phone.

Canonicals words about the new venture. "we’ve brought Android together with Ubuntu, the world’s favourite free operating system, to give you a full productivity desktop that fits in your pocket. Android for the phone experience, Ubuntu for the desktop, all on one device, running at the same time."

 So forget the office PC. Just dock your corporate phone and enjoy Ubuntu. Anywhere. One address book. One set of bookmarks. One place for your text messages and email. No more typing on a tiny screen when all you want is a keyboard and a mouse. Seamless integration of your desktop and mobile worlds. Brilliant.

Users will want at least one dock, complete with monitor, keyboard and mouse. Many will want two of each - one for the office and one for the home. And mobile users will opt for clamshell devices that give them a laptop experience whenever they need it - on the train, on the plane or in meetings.

Desktop productivity goes well beyond the keyboard, monitor and mouse. Imagine projectors with a phone dock built in, so you can carry less to your presentations. And imagine TVs that become home PCs when you dock your phone: perfect for the emerging market where LTE will be the normal way for new users to connect to the Internet.

How to set up a firewall in ubuntu

To protect your computer against unauthorized access by people on the Internet or your network,you can set up a firewall in your ubuntu. Firewalls block connections to your computer from unknown sources, which helps to prevent security breaches. If you use a router to connect to the Internet, the router may already have a firewall configured which regulates connections from the Internet to your network.

following post briefs the set up procedure of firewalls in ubuntu.

Most users will prefer to use Gufw, which is a graphical user interface program to configure UFW(uncomplicated firewall).

Click the below link to install and enable Gufw:

Install the gufw package.

then the below shown dialogue box appears.

click on launch application and agree to install the package.

Now, to start Gufw, choose System → Administration → Firewall configuration

To enable the firewall, simply check the box next to Enabled under “Actual Status”.

The default configuration is to deny connections. This means that a program attempting to connect to your computer will be denied. Certain programs or services which use the internet may require you to add an exception.

To add an exception:

1. Click Add.
2. You can choose from Preconfigured options for common programs and services, or you can manually add port exceptions in the Simple or Advanced tabs.
3. To find out what type of exception a particular program requires, you should consult the help for that program.
