Truth Happens : Redhat's legendary reply to Microsoft (Remixed)

2012-03-02T02:27:00.001+07:00

Here is the new remixed version of Redhat's legendary reply to the Microsoft's anti Linux campaign 'Get the Facts' in 2002. However later in 2009 Microsoft removed the campaign page from its website replacing it will a simple comparison between Windows and Linux.

The Video gives a walk-through of historical criticism on how throughout the history, new technology has been resisted by those who said it couldn't be done. Yet despite opposition, time and again the impossible is made possible by those with determination and vision.

Now the history has witnessed how open source is a better way, a better way of developing technology and a better way of making it accessible. And while there are those who have ignored open source or claimed it wouldn't work or wouldn't last, but at last truth happens.

The video ends with a quotation from Mahatma Gandhi

"First they ignore you...

Then they laugh at you...

Then they fight you...

Then you win... "

Hope you will enjoy the video :)

Track the trackers using Collusion Add-on for Firefox

2012-03-01T14:08:00.000+07:00

Mozilla has come up with the experimental Collusion add-on for Firefox, which lets users see all the third parties that are tracking your movements across the Web. Creating a new tab, Collusion displays an interconnected graph of sites the user has visited. It also shows the tracking sites which are using third-party cookies to track the user on those sites. Mozilla teamed up with the Ford Foundation to develop the Collusion add-on.

Interested users download the add-on directly from here. This add-on does not require a reboot for Firefox, To get started, click on the Collusion icon in the bottom-right corner of your browser. (You may need to show the Add-on Bar to see the icon.)

Boot to Gecko (B2G) : An Open Web of infinite possibilities for Mobile Devices

2012-03-01T02:52:00.000+07:00

Mozilla Foundation today officially announced the launch of its new Mobile OS platform called Boot to Gecko (B2G). For all those who want to know how B2G is different from other Mobile Operating Systems such as Android or iOS, B2G is the Chrome OS of the mobile world and is ofcourse open source. Mozilla called its new in-house wonder "Web as the Platform for the mobile devices". B2G will be able to run any web application just like Chrome OS, so if you are a web developer and already developing web apps you don't need to do anything new, your app will be ready to run on B2G as soon as B2G is in the market.

Web Developers just need to write a small web app manifest for the app to be installed on your homescreen, just like you do it for Google Chrome Browser and Chrome OS for your web app to be download-able from Google Chrome web store.

Another distinctive feature apart from Web as a Platform is the UX called Gaia. It is so open that a user can have a look at the underlying HTML source code of a web app at the press of a hardware button and hack it for personal customization.

What makes Gaia extra interesting is that it is all developed in HTML5, CSS and JavaScript. Gaia code is available on GitHub and one can just check it right now to test or contribute.

Gaia is designed to demonstrate the functionality, reliability and creative potential of the open web as a mobile platform.

The following is a quick visual tour of Gaia, and what it means

Here is a Video demonstration of B2G prototype.

Mozilla also clarified that it has avoided using any major Android components to duck any future patent trolls or licensing issues. Mozilla also managed to strike an alliance with Telefonica and Qualcomm to deliver very low cost phones to users worldwide.

Looks like Android and iOS gonna face tough competition coming days :)

Free Ebook: The Linux Command Line

2012-02-28T11:03:00.002+07:00

Nowadays, most computer users are only familiar with the Graphical User Interface (GUI) and think that Command Line Interface (CLI) is an old-fashioned way to interact with computer. This is not true, because command line interface is expressive way to interact with computer, just like writing letter or message to our friends. It's been said that:

graphical user interfaces make easy tasks easy, while command line interfaces make difficult tasks possible

So, learning command line interface is important if you want to get the most out of Linux operating system. Linux command line is a great tool because we can perform a lot of tasks there. There are many references to learning command line interface. One of them is an eBook I'll post here.

This book is entitled "The Linux Command Line" written by William E. Shotts. This book contains 522 pages and divided into five parts:
Part 1: Introduction
Tells some story related with command line interface.

Part 2: Learning The Shell
Starts the exploration of the basic language of the command line including such things as the structure of commands, file system navigation, command line editing, and finding help and documentation for commands.

Part 3: Configuration And The Environment
Covers editing configuration files that control the computer's operation from the command line.

Part 4: Common Tasks And Essential Tools
Explores many of the ordinary tasks that are commonly performed from the command line. Unix-like operating systems, such as Linux, contain many “classic” command line programs that are used to perform powerful operations on data.

Part 5: Writing Shell Scripts
Introduces shell programming, an admittedly rudimentary, but easy to learn, technique for automating many common computing tasks. By learning shell programming, you will become familiar with concepts that can be applied to many other programming languages.

Three reasons why Ubuntu for Android would be a big boost for high performance sales teams

2012-02-28T02:41:00.000+07:00

Most of the high performance sales teams today are equipped with both Smart Phones and Laptops for their computing requirements both on the move and at the office. Sometime sales people carry a Tablet to reduce the need for both Smart Phones and a Laptop. But Tablets are more costly and not a complete replacement for both Mobile Phone or a Laptop/Desktop.

For sales teams with lesser budgets on their sides, sales professionals need to depend only on their office desktop or on a smart phone alone, with a small screen and no keyboard for typing long emails and proposals.

Ubuntu for Android is now the answer to all these problems, a full fledged productivity desktop with the power of smart phone. Here are three reasons why Ubuntu for Android would be a big boost for high performance sales teams.

Cost: Sales teams keep traveling from place to place both in the city and outside city. On the move carrying a bulky laptop is always troublesome and not always required, thanks to smart phones most of the office work such as checking and replying email, editing documents is a much easier affair than opening a laptop and finding a proper place to work.

With Ubuntu for Android companies are only required to purchase a Smart Phones for their sales professional instead of both Laptop and a smart phone, or only a Laptop (including the cost of Software and AMCs) complimented by a dumb phone. In the office 4-5 docking terminals would be enough for a team of 10 sales guys. Thus decreasing the overall computing cost substantially.

Portability: As we know, sales teams keep on moving and not all sales professionals are present in the office at the same time. On the move sales professionals can work through smart phones, can dock it to a Multimedia Projector on the client side for presentation and back in the office same phone can be docked as a desktop without any need of data transfer from here and there. Ubuntu for Android will thus provide both physical and data portability.

Enterprise Ready: Ubuntu is already a enterprise proven platform for businesses across the world. And by taking the advantage of desktop virtualization, the same smart phone can be used as a thin client with the familiar desktop applications such as MS Office etc. or the CRM application on the cloud. Reducing the need for trainings to work on Linux desktop.

Ubuntu for Android is surely a game changer for both Hardware and Software domains, with the introduction of Ubuntu for Android in enterprise and consumer market prices of dual core smart phones will decrease substantially as compared to both Laptops and Tablets, and companies would also save millions they spend on software for each hardware they procure. Professionals such as sales people will also work efficiently both on the move and at the office with physical & data portability and familiar enterprise ready applications.

Twidge: Twitter Client for Linux Terminal

2012-02-27T21:30:00.001+07:00

Twidge is a terminal client for microblogging sites such as Twitter and identi.ca.

Twidge is a full command-line client. It is designed to be useful when you’re sitting at a shell prompt. It produces output in well-formed and easily-parsed ways, and has various features for working with piped data.

There are other command line tools for twitter which are also available, but most of them are not updated for the changes in twitter security settings.
Here is how you can install and configure Twidge,

Twidge is available in the oneiric apt repositories, so if you are using Ubuntu 11.10 you just need to install Twidge using the install command.

$ sudo apt-get install twidge

But if you are using any other version of Ubuntu, you need to manually add the repositories for Twidge.

$ sudo gedit /etc/apt/sources.list

Append the following line at the end of the text,

deb http://ftp.de.debian.org/debian squeeze main

Save this repository to your sources.list to be able to download Twidge. In order to install from the command line, run:

$ sudo apt-get update

$ sudo apt-get install twidge

Twidge Setup:

Issue the following command in the terminal

$ twidge setup

Twidge Setup will generate a URL for the authentication (see the below image), copy the URL and paste it into your browser, it will ask you to login with your login credentials, just login and it will generate an authentication code.

Enter the authentication code in the terminal, and you are done and ready tweet the geek way :)

Some useful Twidge commands:

For the detailed description for the twidge commands look inside Twidge man pages.

$ man twidge

Or, you use lscommand to see the full list of commands at glance,

$ twidge lscommands

Here are some quick commands for day to day usage,

Status update:

$ twidge update

And then typing your 140 character update,

Check your @replies:

$ twidge lsreplies

Check most recent updates:

$ twidge lsrecent

Lets tweet the geek style :)

Lightspark: Open Source Alternative to Adobe Flash Player

2012-02-25T20:53:00.000+07:00

Adobe has recently announced its plan to abandon Flash Player for Linux platform (through Netscape API to be specific) and limit it to Pepper API which is only available in Google Chrome. Thus leaving Firefox, Opera and other small browsers in doll drums.

It is a good time to look for Alternates, and Lightspark is one such alternate and is open source.

Lightspark, is an LGPLv3 licensed Flash player and browser plugin written in C++/C that runs on Linux. Lightspark support Adobe’s newer Flash formats and AVM2 virtual machine.

The Lightspark player is completely portable. Lightspark has been successfully built on Ubuntu on PowerPC, x86, ARM and AMD64 architectures.

Installing Lightspark in Ubuntu:

For the latest version of lightspark, use the following PPA for Ubuntu 11.10 and 12.04:

$ sudo add-apt-repository ppa:sparkers/daily

$ sudo apt-get update

$ sudo apt-get install lightspark browser-plugin-lightspark

How to Clear Recent Used Document Log in Ubuntu

2012-02-25T18:23:00.001+07:00

Every Operating System (without no exception for Ubuntu) usually create user activity log that log in at the time, some log that are often found are recent used document, the presence of recently used document log sometimes makes people uncomfortable, they afraid if their friend know what they just did using their computer, it's about privacy.

You can perform many various ways to make Ubuntu does not showing any recently used document, here the easiest and fastest way to do it without installing extra application :

The list of recent used document is save in <home directory> /.local/share/recently-used.xbel, the fastest way to make you untraceable is delete the recently-used.xbel, do as follow :

rm ~/.local/share/recently-used.xbel

Create an empty file to replace the file that you just delete above :

touch ~/.local/share/recently-used.xbel

Make sure that recently-used.xbel can't be modified (immutable), some reference about immutable file can be read in here :

sudo chattr +i ~/.local/share/recently-used.xbel

Chattr is equal to attrib in windows, System or user can't edit, remove, or modify recently-used.xbel. To revoke last action and make the file editable, do as follow :

sudo chattr -i ~/.local/share/recently-used.xbel

Before

After

Clear Recent Used Document using Application

Another ways that you can do to clear recent used document is using a program, there are many program that help you to manage user privacy and log in Ubuntu (we will discuss it later), Some application that may help you to manage user activity log and privacy control are :

BleachBit.
Activity Journal.
Ubuntu Tweak.
Activity Log Manager.

Hopefully this will help :)

Linux Kernel 3.3 Will Let You Boot Into Android

2012-02-22T22:47:00.000+07:00

With the release of Linux Kernel 3.3 you will be able to boot into Android userspace without any modifications (to the kernel) but not with very good power management, The 3.4 kernel release will hopefully have the power management hooks that Android needs in it, along with a few other minor missing infrastructure pieces that didn't make it into the 3.3 kernel release."

Revealed Greg-KH who recently joined The Linux Foundation after quitting from Novell SUSE.

This puts Android right there with Gnome and KDE as just another desktop environment for GNU/Linux.

Ubuntu for Android Is much more than what we thought about it

2012-02-22T15:58:00.000+07:00

In a recently release video demo of Ubuntu for Android from canonical, Ubuntu for Android looks even more promising than a converged Mobile Phone and a Desktop PC.

It can also be transformed to the Ubuntu TV once docked to a TV through HDMI port. So your Smart Phone is not only a full fledged desktop inside your pocket but a Media center too.

Here is the Video demo of the Ubuntu for Android concept.

Mark Shuttleworth also confirmed on his blog that Ubuntu for Android is not the Ubuntu Phone announced last year in October and is a separate project altogether.

Ardesia: Digital Sketchpad for Your Desktop

2012-02-22T11:31:00.001+07:00

Ardesia is a digital sketchpad for your desktop. It enables you to make colored free-hand annotations with digital ink everywhere on your desktop, record them, and share on the network. Ardesia is a easy-to-use, simple, and useful application, especially for those who often make a presentation or lesson to another by showing the computer screen. You can annotate, mark, highlight important objects on your desktop with Ardesia. This make your lesson easier to understand by your audiences.

I have tried this application long time ago when I used Ubuntu Natty (as shown in picture above) and it did well. Recenty, I tried Ardesia on Ubuntu Oneiric and it still worked great!

Install Ardesia on Ubuntu
In fact, Ardesia is available on Ubuntu repository, but it doesn't work on Ubuntu 11.10 Oneiric Ocelot due to a dependency issue when installing. Alternatively, you can download the *.deb package here and run these commands to install Ardesia on your system:

sudo dpkg -i ardesia_1.0-1_i386.deb

sudo apt-get -f install

Replace "ardesia_1.0-1_i386.deb" with your exact file name of Ardesia *.deb package.

For additional information, below is a demo video about Ardesia:

Meet New Ubuntu Start-Up Sound

2012-02-22T11:00:00.001+07:00

Next Ubuntu release will be accompanied with new start-up sound, the sound which have been chosen through this survey will be used as Ubuntu start-up sound replacing the old ubuntu start-up sound which has been used for about 5 years.

The Winner
Canonical design team provide 4 sound candidate to be chosen (from finalist), survey which followed by over 2000 participants voted candidate number 1 as the winner, here the result of the survey :

Ubuntu Start-up Sound Survey Result

The Chosen Candidate
here's the winner, Does this sound feel like Ubuntu ?

Next step, canonical design team will make this sound ‘more human, less synthesised’, lowering the pitch, increasing ‘the warmth of the tone’, and make it available in Ubuntu 12.04.

There is a few question, from previous post that confirmed by Jeremy bischa, for some reason Ubuntu 12.04 will be no sound at startup, does this survey mean that start-up sound will be sounded again in Ubuntu 12.04, is anyone could confirm this ?

Ubuntu for Android: Convergence of Mobile Phone with Desktop PC

2012-02-22T03:06:00.000+07:00

Ubuntu for Android! Well this could be a the next game changer for both Mobile Phones and PC market, latest of the innovations which could change the way we do our computing, at a time when Mobiles and Tablets are out numbering the sales of Desktops and Laptops. And it seems that desktop would be dormant and obsolete in few years fighting and competing with Mobile Phones and Tablets.

Even thought the concept is not much different from Motorola Aetrix 4G docking Phone, but if your smartphone can boot with the Ubuntu on a desktop we can expect much more.

Ubuntu for Android is the beginning of the convergence of Mobile devices and Desktop PCs in a real sense. Something, I would call a Personal Thin Client, though not a thin client in a real sense.

In simple terms Ubuntu for Android is a full Ubuntu desktop, on a docked Android phone. In terms of Hardware requirements, your Android phone should be equipped with a dual core processor.

Ubuntu for Android provides a full desktop experience, including office software, web browsing, email and media applications, on Android phones docked to a screen and keyboard. Thanks to tight integration with the Android service layer, the transition between the two environments is seamless, making it easy to access the phone's services from the desktop when docked.

With Ubuntu on Android you can enjoy full featured Web Browsing with your favorite desktop browser with your smartphone but on a much larger screen real estate. Ubuntu for Android also integrates data access such as contacts, messaging, calender & making calls etc., in both Phone and Desktop modes.

Currently, Ubuntu for Android is only a prototype and Just like recently announced Ubuntu for TV, Manufacturers and interested parties are being encouraged to speak to Canonical if wanting to take advantage/learn more about the technology.

Script: Remove Unused Old Kernel

2012-02-21T16:25:00.001+07:00

Many Ubuntu users who upgraded Linux kernel to newer version might encounter something messy in GRUB menu. The old kernel is still there and appears on GRUB menu although we don't use it because we already have a newer version to boot. So, today I'd like to share my old post on TahuTEK.net about simple script to remove unused old kernel on your system automatically. Although this is an old post, it still works until today. I have been using it since I've moved to XFCE.

As shown in the figure above, there is an older kernel in the GRUB menu (2.6.32-21) although we have installed a newer version of kernel (2.6.32-22). To remove the old kernel, simply create a shell script as follow:

#/bin/bash

ls /boot/ | grep vmlinuz | sed 's@vmlinuz-@linux-image-@g' | grep -v `uname -r` > /tmp/kernelList

for I in `cat /tmp/kernelList`

do

apt-get remove $I

done

rm -f /tmp/kernelList

update-grub

Copy the above script into your favorite text editor and save it. For example, I give "clean.sh" as filename of the script.

Before executing the script you need to add "execute" permission to the file:

chmod +x clean.sh

Now, whenever you want to remove old kernel, simply execute the script with root privileges:

sudo ./clean.sh

For your information, you can also use Ubuntu Tweak to perform such a task. But, in any condition, you don't have Ubuntu Tweak installed on your system, you can use this simple script to remove old kernel.

How to Open .dbf File and Export It To MySQL

2012-02-20T12:23:00.000+07:00

A few days ago I was engage with building web-based application that intended to discover duplicate data in excel files, at first this jobs look simple, but after knowing the amount of data which will processed (35 Million Data) and stored on nearly 70,000 different excel files, hmm .. This work may not seem as easy as imagined.

A little problem appears when I wish to add some data from .dbf (exported from foxpro) to MySQL, it was a new experience for me. The first move that I usually do when I meet some unreadable file format in ubuntu is go to Ubuntu Software Center and search program using keyword file formats that I want to be opened (example : if you want to open dbf format, you can search program using keyword 'dbf'), Yatai .. as usual Ubuntu Software Center never disappoint and always gives a solution.

Find Application in Ubuntu Software Center

Gnumeric Spreadsheet to Open .dbf
First application that I got from Ubuntu Software Center is the Gnumeric Spreadsheet, Gnumeric is a spreadsheet application that interoperates well with other spreadsheets. you can open commonly used spreadsheet file formats like xls, sxc,csv, dif and more, using this application I can see the contents of .dbf but I can't be directly exported it to .sql (MySQL), all action must be done manually and less time consuming. You can just use Gnumeric Spreadsheet as a dbf reader only, to perform other actions such as exporting to sql you might need another application.

dbf2mysql: export .dbf to sql (MySQL)
Second application that I got from Ubuntu Software Center is dbf2mysql, this application is quite small if compared with Gnumeric Spreadsheet, the size is only 29.1 kB, but even small dbf2mysql is quite powerful. dbf2mysql is designed to perform a specific function that is exporting dbf database format into mysql.

Weather Information in Linux Terminal

2012-02-18T02:37:00.000+07:00

Linux Terminal makes life easy for day to day administration on a Linux Desktop. And if you are a Power user and spend most of the time on the command prompt, you might want to have some dynamic information such as Weather condition available each time you open the Terminal.

Here is a way to get Weather Information in the Linux Terminal both in graphic (gnome, KDE, Unity) and text login (Ctrl + Alt + F1 to F7) modes.

First install the weather-util package from apt repositories.

$ sudo apt-get install weather-util

You’ll need your local weather code, which you can get from this website.

For Graphic Login:

Open the .bashrc file

$ sudo vi ~/.bashrc

Press Insert, And append the following lines at the end of the file.

# Weather Information
weather -i CODE

Where CODE is the code of your location, like VIDP is the code of New Delhi in my case.

Press Esc, and :wq to save and exit the vi editor.

Close the Terminal and reopen, it will display the weather information before the bash prompt.

For Text Login:

You first need to create a script in the appropriate location using vi editor.

$ sudo vi /etc/update-motd.d/98-weather

Press Insert and enter the following code, replacing CODE with your local weather code

#!/bin/sh
echo
weather -i CODE
echo

Press Esc, and :wq to save and exit.

Make it executable using chmod

sudo chmod +x /etc/update-motd.d/98-weather

Press Ctrl + Alt + F1 and login to see the script working.

Voila :)
