How to know you are running a 32-bit or 64-bit Ubuntu?

If you have forgot what bit version of Ubuntu you are running.

There is a nice and simple command line program called uname that tells the current bit version


Open Terminal.






Type 
uname -m 
in terminal and hit enter.





  • If the response is i686, you have a 32-bit version of Linux.
  • If the response is x86_64, you have a 64-bit version of Linux.

If you want to know more details like Kernel version, Time stamp etc..

Try  
uname -a

Fix a 'installation of packages from not authenticated sources' error in Ubuntu 11 10

The first thing i did after i bought my first laptop was changing it to dual-boot with windows 7 and Ubuntu. I installed Ubuntu 11 10. Now within hours i updated my Ubuntu with few software's likes vlc, shotwell,wine. Later on that week i found few updates for my ubuntu. It had updates for chrome, ffmeg, some updates on system utility too.

But when i try to install updates it show up message

"the action would require the installation of packages from not authenticated sources in ubuntu 11.10"
I searched few Ubuntu forums and blogs, and found this simple solution. Which i share with my readers below.


In Ubuntu panel, click activities > applications> update manager


2) Look for the settings in bottom of update manager, Click.
3)On the Software Sources window, click on the Ubuntu Software tab.


4)Under Downloadable from the Internet, put a check on  Source code.



5)  Close the window and the changes will be applied.

6) On Update Manager, click on Install Updates.



After checking 'Source code' (which was not checked in my case) The error did not show up again.


Hope this works for you too. 


Let me know, it worked for you or suggest me any other method.

Mozilla to Develop OS based on android!







Mozilla, who are renowned for their successful internet browser, are entering the mobile race, developing a new web-centric OS that will directly compete with Google, Apple and Microsoft.

If the name Mozilla rings any bells it's because they're the tech boffins who put together Internet Explorer, the browser that Windows defaults to. Mozilla took the leviathan computing company on with its Firefox browser, and today it stands as the second most popular browser worldwide.

Now the company who was underdog to Microsoft looks to be playing the same role, but this time against internet mogul Google.

Announced on the Mozilla discussion forum, Mozilla have begun coding for phones and tablets. The BBC revealed the mobile operating system will draw on Android code, with Mozilla writing as much fresh code as possible. The hybrid-like operating system will be named Boot To Gecko. 

It is an unusual name for an OS, until you remember Gecko is the rendering engine employed by the Firefox browser that interprets web page coding and displays it in a screen-friendly format, a homage to its origins.

Even though Android coding will form the operating system's foundations, Mozilla hope to add a much more open wrapper around it than Google currently do, making it more versatile as an operating system.

Its shared foundations will also make Boot To Gecko compatible with the same phones as Android, competing as a direct alternative to Google.

Often, when you select a link from an application native to the Android or iOS market, the operating system will have to open a new webpage in the browser. Boot To Gecko aims to limit this by making applications much more web-centric.

If the venture proves successful, Mozilla will be waging war against industry giants, with Google, Apple and Microsoft dominating many facets of the technological world. 



Mozilla have acknowledged the project is in infancy and have chosen to make the development public in hope it will attract talented enthusiast coders who will contribute to the Boot To Gecko's cause.

According to their project team, all of the code development will be completed and shared with the public as soon as it is written.

Researcher Andreas Gal, who announced the development, admits the company has set a high target, but wants to do it "the way we think open source should be done.

Gal says his ultimate goal is to break "the stranglehold of proprietary technologies over the mobile device world," implicitly referring to the practices of Apple, Windows Phone and Google.
