How was the year 2012 for Linux?

2012 has been another year of records for Linux. The operating system is the fastest growing platform across multiple industries and is inspiring new projects every single day. Join us as we review this amazing year and celebrate Linux and its global community of developers, contributors and sponsors.

Ubuntu for phones

Canonical announced the future of Ubuntu for smartphone devices, including Ubuntu for Phone and Ubuntu for Android.

Ubuntu for Android or your phone is the PC !

How would you like a PC that fits in your pocket?

Now multi-core Android phones can be PCs too. Ubuntu for Android enables high-end Android handsets to run Ubuntu, the world’s favourite free PC desktop operating system. So users get the Android they know on the move, but when they connect their phone to a monitor, mouse and keyboard, it becomes a PC.

Simple failover cluster using UCARP on Ubuntu

Lazy Geek -:)

In this tutorial, I’ll show you the steps to create a simple failover cluster on Ubuntu using CARP. To make the things meaningful,we’ll create the cluster for Apache service but you can use it for any other service, which relay on IP.


Here is my Setup:

PrimarySrv: This is the main server, where I configured the apache and which act as Master (IP:
SecondarySrv: 2nd Apache Server where I configured the apache exactly like on PrimarySrv (IP : : Virtual IP address,created using Ucarp.

Ucarp is really simple, it works like this,when the PrimarySrv is up,it will assign the virtual IP to it, in case that PrimarySrv is down then it will assign virtual IP to the SeconadrySrv and when the PrimarySrv will come online, it will assign the virtual IP once again to it.

I assume that you configured…

BackTrack Review by Example

A BackTrack 5 R3 review from Linux Action Show.

We use BackTrack 5 R3 to hack a remote box, and get root access. We cover the high and low points of the security toolbox distribution.
Plus – The outreach from the Linux community helping one of our own receive life saving medical treatments.
Then it’s your feedback…
And so much more!

Compact *.vmdk does not work (for Fedora guestOS) in VmWare Player

I have a Fedora Linux Guest OS in a VmWare Player.
The hard drive on the virtual machine (*.vmdk file) got to big and I was looking for a way to Compact it.
The compact operation from VmWare Player->Virtual Machine->Edit Virtual Machine Settings->Hard Disk->Utilities->Compact did not do the trick.

The solution came from a VmWare forum thread, the 4-th post from the top:

Assuming the VmWare virtual disk is not pre-allocated and the filesystem is ext4 you will have to manually prepare it to be shrunk.

In the VM, in a Terminal become root and then copy and paste the following command, as is, and then press Enter:

dd if=/dev/zero of=wipefile bs=1024x1024; rm wipefile

Wait for the command prompt to return and then shutdown the VM and then from the Virtual Machine Settings for the Hard Disk select the Compact command from the Utilities button.

The solution worked like a charm.

Linus Torvalds: Linux succeeded thanks to selfishness and trust

An interesting interview with Linus Torvalds by BBC.

Linux creator Linus Torvalds will find out later if he has won the Millennium Technology Prize and an accompanying cheque for about 1m euros ($1.3m; £800,000) from the Technology Academy of Finland.

He has been nominated for the award in recognition of his creation of the original Linux operating system and his continued work deciding what modifications should be made to its kernel – the code that lets software and hardware work together.

Today variants of the system power much of the world’s computer servers, set-top boxes, smartphones, tablets, network routers, PCs and supercomputers.

Ahead of the announcement Mr Torvalds gave a rare interview to the BBC.

The interview is available at the link.

Mozilla – Bringing the Open Web to Mobile Devices

Here is an interesting peace of news – Mozilla is thinking of making an open “Open Web as a platform for mobile devices” as they call it, named Boot to Gecko project.

The Mozilla link of the project is http://www.mozilla.org/en-US/b2g/ and the article from Mozilla wiki about this – https://wiki.mozilla.org/B2G

An interesting first look into this project in on lockergnome website – full link : A (Very) Early Look at Mozilla’s Boot2Gecko Mobile OS .

The answer of an question on Mozilla Wiki make me think …

Is B2G based on Android?

No. B2G uses some of the same low-level building blocks used in Android (Linux kernel, libusb, etc) in order to reduce the burden on ODMs/OEMs to bring up B2G on new hardware. However, B2G is not based on Android, and will not be compatible with the Android stack (in particular B2G will not run Android applications).


The highlights of the project, from Mozilla’s side are :

  • New Web Standards – The project will produce an implementation of these new Web standards to free mobile platforms
  • Freedom From Proprietary Mobile Platforms.
  • Opportunities for Developers – Using HTML5 and the new Mozilla-proposed standard APIs, developers everywhere will be able to create amazing experiences and apps.
  • Customization for OEMs & Operators – OEMs and operators will be able to provide content and services across their entire device portfolio, regardless of OS.
  • Consumer Freedom – Consumers who use devices based on the Open Web platform will be able to easily access and download their own content regardless of which OS they use.

This is certainly an interesting project to watch in the future !

BackTrack 5 R2 Linux Officially Released

One interesting piece of news is that BackTrack 5 R2 Linux Officially Released.

After months of development, bug fixes, upgrades, and the addition of 42 new tools, we are happy to announce the full release of BackTrack 5 R2 available for download now. Running our custom-built 3.2.6 kernel with the best wireless support available, this is our fastest and best release of BackTrack yet. In the past few weeks, we have had a flood of submissions to our BackTrack Redmine Tracker with submissions for many new tools and dozens of packages that needed to be updated and this has helped to make this one of the strongest releases we’ve ever had.

The Raspberry Pi Launch

Here is a picture of the Raspberry Pi computer :

Here is more info of the tiny computer from http://www.raspberrypi.org/ website.

Model A or Model B?

All of the first units to be produced are the $35 Raspberry Pi Model B. These are the more fully featured versions of the Raspberry Pi. The main difference from the Model A is that they include an Ethernet port, and 2 USB ports.

We’ve been working hard at cost reduction over the last few months, and we’ve been able to make one significant change to the Raspberry Pi lineup. The $25 Model A has been reworked to include 256MB of RAM – double what we were originally planning to offer – and will be going into production immediately.


We are launching with Model Bs as there has been a much larger demand for them from the community. This first launch is aimed at software and hardware enthusiasts, makers, teachers and others who want to build exciting things with the Raspberry Pi before the official educational launch, which will happen later in 2012.

This means that when we launch into the educational market, there will be an experienced community of people using and making things with the Raspberry Pi. Software will be more mature and free of obvious bugs, and easier for children and educators to use.

And yes, this PC runs Linux !

Ubuntu for Android
