mozilla 15th Birthday celebrated at Durgapur

Today is the march 31st, 2013 i.e. Sunday and mozilla has become a 15th year ever fresh organization with a mission to promote openness, innovation and opportunity on the web. To celebrate this auspicious day, i , Biraj Karmakar, Umesh Agarwal, Amit Kumar Thakur, Gaurav Kumar, Mrityunjay Kumar Singh, Subhendu Ghosh, Sayantan Datta, Jeet Biswas and others gathered at 01:00 P:M near Bidhan nagar, Durgapur and cut the cake to celebrate mozilla 15th Birthday.

Firefox-Hindi-Localization-Sprint:- A live contribution

Everybody wants to be a contributor of a big emerging Mozilla community. But by using an application like “Mozilla Firefox”, he is already a contributor. But as time changes, ideas comes up, people wants to do more. So, persons wants to add something in the application. So that if anybody is using that application, he goes there and say “following things are added by me.” and by saying that he makes himself and community proud.

By thinking upon this, I shahid Ali Farooqui and Rajesh Ranjan came up with an idea to organize an virtual event named “Localization Sprint” where people can directly come, participate, learn and contribute to an application with a common goal in a team.

For that we have targeted “Firefoxos” and organized “Firfox-os-Hindi-Localization-Sprint” on 24th February, 2013. The event was successful by making a submission of 4000 words and we have got new contributors to Mozilla Hindi Localization team.

From the success of first sprint, Vineel has gave me an idea to provide prizes to the contributor who has translated maximum number of strings. This will encourage contributors to do their best.

And after that I and Rajesh Ranjan organized another “localization sprint” targeting for “Mozilla Firefox” named “Firefox-Hindi-Localization-Sprint” on 03rd March, 2013 by using #india channel on server and #indlinux channel on server by using Mozilla pootle server. The event was more successful than previous one by mading a submission of more than 8000 words (Firefox-2900 +webparts -5500) by 11 participants.

The 11 participants who had made this sprint successful are:- Amit Kumar Thakur, Keshav Kumar, Sayan Chowdhury, Chandan Kumar, Gaurav Kumar, Rajesh Ranjan, Saurav Agarwal, Komal Gandhi, Abhishek Potnis, Suraj Kawade and Neeraj Kumar.

The maximum submission are made by Amit kumar Thakur and followed by Keshav Kumar.

Their Contribution and statistics are given on etherpad:

The event page for the sprint is:

I would like to a special thanks to Mozilla community for creating the pootle interface for Mozilla software localization. Without it this type of sprint is not possible earlier.

I would like to thanks all the community members for making this event successful.

#dgplug!! Now 8 year’s old.

Today #dgplug (Durgapur Linux user Group) completed 8 years.
On the same day i.e. on 8th september, 2004 some young genious minds like Kushal Das had taken a golden step for the promotion of Free and open source Software(FOSS) where students can come, learn, share their knowledge and contribute to FOSS and founded a Community named Durgapur Linux User Group which is further popularised as a dgplug. Later on Soumya joined together.

When i was in 2nd semester first year at Dr.B.C.Roy Engineering College, Durgapur, had met kushal Das Who had visited our college to give a talk on Python Programming. There i came to know about Open source software and interacted with a group of people like: Rtnpro, Kishan who were contributing to FOSS already. Kishan along with sayan and koustawa helped me in learning fedora Installation. After that under the guidance of kushal and rtnpro, i had learnt fedora RPM packaging and Python programming. Later i had attained dgplug summer training in 2011 and learnt a lot of things related to programming languages and shell scripting. Mbuf tuaght us Communication guidlines that had helped me in irc chats.

But my contribution to open source begins, when Rtnpro and Bamacharan inspired me through violent kicks. They taught me to try my hands on localization of open source Software on transifex. With the support of rtnprokushal and Rajesh ranjan, now i am a open Source technical translator for various projects.

As the 3 years of my college life passed, i started inspring out the college students and to share my skill and knowledge with them. The first achievement i have gained when my name got published in the author lists of VlC media Player 2.0.3. Now, lots of students are coming and joining this community  and is growing day by day and getting bigger and stronger. A day will come when dgplug will cross its sky limits.

This group has given a greater height to my carreer and arouse the interest of programming. I am really thankful to all who helped me in this journey.

[root@chandankumar chandankumar]#

When i shown this error on #fedora-channel they told that yum has broken.

The reason of breaking of yum is the plugins that i have installed to increase yum downloading speed.

To overcome this error, i have tried the following commands related to you.

#yum clean all

#yum repolist enabled

#yum –disableplugin=presto makecache

# yum –disablerepo=\* –enablerepo=fedora makecache

#yum –disableplugin=axelget makecache

But nothing has happened.

i have queried for the repo’s list by using the command #rpm -qa, to see that my rpm list is working smoothly and yum is not working.

At last i have thought to remove that package from yum plugin. Go to /usr/lib/yum-plugins/ directory and list that package and remove that yum  plugin that causing yum to be broken by using rm command. After that everything is working fine.

i have done the following things.

  1. [root@chandankumar yum-plugins]# ls
  2.   fastestmirror.pyo  langpacks.pyc   presto.pyo             refresh-packagekit.pyc

Magahi locale created

Magahi (mag), one of the ancient language spoken from the age of Buddha has now got its own locale for localization in open source. It belongs to devanagari script and spoken by 13 million people in the region of Bihar, Jharkhand and some parts of West Bengal. It is similar to maithali language. So, we with the help of fuel community started localization of open source through magahi language.

What is Locale?

In computing, Locale is a set of parameters that defines the user,s language, country and special variant preferences that the user wants to see in their user’s interface. It consists of a language identifier and a region identifier.

Create a locale file for a language:

Download a general locale file of any previous language having its locale like magahi locale file from here  (as i have done.). Fill all the required information and convert it into UTF-8 encoding with using the command in python interpreter by using the command “>>> w = “प्रविण” >>>w.decode(“utf8”) “.

For compiling the locale file visit here:

How to create a locale for a new language?

Since that new language has no locale in the different operating system. So, it is a bug.

So, we have to file a bug report either in redhat Bugzilla or Sourceware Bugzilla. Following are the steps given for filing a bug for a locale of a new language.

  1. Go to  Redhat Bugzilla or Source Bugzilla Home page.
  2. Create your own user account.
  3. Now log in into your account.
  4. Now go to “file a bug” link.
  5. File it under “localedata” component.
  6. select product “glibc”.
  7. Write Summary of the bug as “Adding a new language locale”.
  8. Attach the Locale text file for that language.
  9. In comments write about that language like about its origin, total speakers and why to create locale for this language?

After that locale will be created when bug will be can view this bug here:

In this way i have created the locale for magahi language with the help of rajesh ranjan, jassy, pravin satpute. Thanks a lot to all of them.

Contribution to GNOME 3.4 through hindi translation

The day i remember when Rajesh Ranjan told me to join hindi language translation team of gnome was one month ago from today. I joined the gnome hindi language translation by registering myself as a translator on l10 site. From that day i have translated the following projects under gnome community listed below:

gnome-terminal, yelp, vino, totemnautilus, ligbdatagucharmap, gtk+-properties, gnome-user-share, gnome-system-monitor, gnome-setting-daemon, gnome-power-manager, gnome-packagekit, gnome-bluetooth, gnome-control-center, evolution, empathy, brasero, evince, cheese and many more..

For all these  translations all credits goes to Rajesh Ranjan and Karunakar.

A special thanks to rtnpro for warm push ups. 

dgplug meeting at bcrec

For the first time, I sayan, gaurav, biraj and koustava all together organised the dgplug weekly meeting at college library in Dr.B.C.Roy Engineering College, Durgapur during evening at 5:30 p:m. We met 20 students for the first time after the python workshop taken by kushal in february. We had asked about the queries related to python and open source from them. We told them about the irc and #dgplug channel at freenode through X-chat and also showed them to talk on irc by talking with rtnpro and biraj . We have also told them to register their name at dgplug mailing lists. After that we have fixed the next meeting on monday to do fedora installation and face the issues related to fedora installation.

Finally the meeting ends with a happy smile. Thanks to all dgplug members at bcrec.
