GSoC-2016 Journey (In brief)

Three months of coding is about to end.It has officially begun on May 23rd and we are getting near to the final submission deadline on August 15th.

You can checkout my Debian wiki page to know more about myself.

I have worked on improving voice, video and chat communication (Real Time Communication) with free software, one of the RTC project for Debian.

My mentors are Iain.R.Learmonth and Daniel Pocock.Both of them were dedicative and I could learn many new things from them within these three months.I have contacted my mentors through personal mail, Debian outreach mailing lists and IRC(#debian-data and #debian-soc). They were very responsive to my queries. Thank you Iain and Daniel for improving and enlightening me.

My initial task is e-mail mining. I have to allow the client to login to the mail using IMAP, extracts the “To”, “From” and “CC” headers of every email message in the folder and then scan for the phone numbers, SIP addresses, XMPP addresses in the body  of the message.These extracted details should be written in the CSV file also.The extracted phone numbers, SIP addresses,  XMPP addresses and ham call signs should be made into a click able link using Flask.

I have also attended DebConf-16 (conference of Debian developers, contributors and users) in Cape Town in the middle of three months (Form July 2nd to July 9th).I gave a talk on my progressing GSoC project.I have learnt many new things about Debian, their projects and their packages apart form my GSoC project.I have  met Debian developers, contribuors and some of the fellow GSoC students.

I have written previous blog posts related to GSoC-2016 in the following links.

GSoC-Journey till Mid term

Weekly Report for GSoC16-week 1 and week2

Weekly Report for GSoC16-Community bonding period

Weekly reports sent to Debian-outreach list.

Email-Mining is the repository I have created on GitHub to work on my project.

I have divided the tasks and coded individually to combine together.Snippet folder in the file contains the code for each tasks.

Following are the commits I have made in the repository.

My tasks have been extended to add a gravatar on the page listing details for each email address, maintain a counter for each hour of the day in the scraper for each mail, show a list of other people that have been involved in email conversations and make the contact information on the detail pages machine readable.

My mentor suggested me to work on at least three issues before final submission.I have worked on each of them individually in the snippet folder except the last one.I will be working on it after GSoC. script contains the final code which combines all snippets into one.

Three pull requests are to be merged after the confirmation from my mentor.

These are the abstract about what I have done within these three months.

It was an amazing and thrilling coding ride.

Stay tuned for the elaborated blog posts with DebConf experience and many more.



GSoC-Journey till Mid term

Hi readers,

Here comes my journey till the mid-term (June 21st) as a blog to share my experience.

I  have previously worked on some social related projects such as “smart guidance for blind” and “sensor based wireless controller”. I have been selected as a speaker for FOSSASIA-16 (Asia’s premier technological event)to talk on the project “smart guidance for blind”.FOSSASIA speakers. It was a great experience participating in the technological event in Singapore science centre.Got an opportunity to meet open source contributors from all over the world(even though it is an Asian event, participation was all over from the world). There were pre-meetups for FOSSASIA on the day before three-day event.I have attended the one organised by RedHat, Singapore.Discussed on many topics related to open source.

Three days of FOSSASIA event was a great experience.It was the second time as a speaker in an international conference.My talk was on the second day.Sharing is the best way to increase your knowledge. Talks and workshops were brainstorming.Learnt many new things and got the courage to contribute to the open source.Met Daniel Pocock in Debian exhibition table.Meeting awesome people can be the turning point of life.Had a discussion about the Debian projects and it motivated me for open source software.We have discussed about the Real Time Communication and was encouraged to apply for GSoC  (Google Summer of Code). As per our discussion, prepared the project proposal on “improving voice,video and chat communication with free software” and submitted it for GSoC. I have been selected to contribute for Debian with stipend from Google.

This was my first application for GSoC and I have been selected to contribute for open source and free software. I would like to thank Google and Debian for giving this amazing experience.

Learning and coding have begun.Updated my laptop with Jessie, latest version of Debian.Get acquainted with the new platform.Got to learn many things about Real Time Communication.Learnt more about SIP, XMPP, peer-to-peer technology to work on my project.It’s always better to be clear with theory before coding.When it comes to voice and video over IP, most people nowadays are quick to use Skype, Whatsapp, or Viber. My main goals of the project are helping people to avoid using proprietary communications tools like Skype, Viber and WhatsApp and simplifying the setup of free alternatives like Jitsi, Linphone, Ekiga, Tox (qtox), Mumble.Downloaded some of the already available open source VoIP to find the problems behind it and improve it further.Bootstrapping any business relevant network based on these free alternatives is still hard.

Would you like to list the senders, receivers and date of the messages in the inbox  of your mail.Python has a library file IMAP which can be used to connect to an email account, examine every message in every folder and look at the “To”, “From” and “CC” headers of every email message in the folder.

Do you have phone numbers and other contact details in old emails? Would you like a quick way to data-mine your inbox to find them and help migrate them to your address book? Got the help from phonenumbers library for parsing, formatting, and validating international phone numbers.I would like to share how I imported this library file into my coding.Download the given library file and open the file in the terminal.Type

$ python install

to install the library file.Now you can call the functions by importing phonenumbers.

You can go through the code in my GitHub profile here.(Recently started committing my projects in GitHub)

Iain R. Learmonth joined my journey as a mentor.Helped in solving some issues in my coding through GitHub.

It was a wonderful journey till now.Will be working further to improve voice, video and chat communication with free software.Stay connected to know more about my  further journey through GSoC.


Weekly Report for GSoC16-week 1 and week2

After introducing ourselves to the community, we start contributing to the open and free source software. Since this is the first week,  I have went through theories which would help me in coding. Before coding it is always safer to refer to theories so that we don’t need to spare time in debugging.


The following were my week 1-4 plans:

  • Getting familiar with Python and coding for connecting to an email account (using IMAP) and examines every message in every folder.
  • Writing a basic Python script to look at the “To”, “From” and “CC” headers of every email message in the folder. Identifying all the names and email addresses and writing them in a CSV file.
  • Scanning the body of each message looking for phone numbers.(for messages in plain text format)
  • Cleaning up the phone numbers and write them in international format and putting those in the CSV file too.(Telify recognizes phone numbers on web pages or in email messages and converts them into clickable links. This works with many CTI applications, SIP clients, Skype, Netmeeting, snom phones, the AGFEO TK-Suite client, SerVonic IXI-PCS and others. In general, all telephony software, devices or interfaces which can be controlled by using a URL, will most likely enable you to call a phone number directly from your browser or email client.

These two weeks I have completed my first two tasks in the list.I have committed and pushed my works in GitHub.

Successfully logged into the email account using IMAP and examined each folders.Examined inbox to extract  “To”, “From” and “CC” of the last message received.Trying to extract all message details to put in CSV file.

Weekly Report for GSoC16-Community bonding period

April 23rd to May 23rd

The period of introducing ourselves to the Debian community. I have updated my debian wiki page to introduce more about myself to the Debian community.

There was a webRTC session of MiniDebconf through Jitsi on 3oth April to know more about the Debian resources.

During this period  I have updated my PC with the Debian latest version, Jessie and got practised with the new platform.I have also learnt some basic theories on my project such as VoIP and IMAP. I was assigned by my mentor Daniel Pocock  to work on telepathy reSIProcate.

  • Steps to install reSIProcate

System used

  • Debian GNU/Linux 8.3 (jessie)
  • Ubuntu 14.04.4 LTS (trusty)


First you have to configure the telepathy-qt library properly to be able to install reSIProcate. It’s important to notice that you shouldn’t install telepathy-qt from apt-get because in this way it wont have the telepathy-qt4-service shared library.

$ mkdir ~/telepathy-qt-stuff
$ cd ~/telepathy-qt-stuff
$ git clone
$ cd telepathy-qt-debian
$ git checkout jessie-build-all-shared
$ cd ..

Then you should download the tar in the telepathy-qt-stuff folder and continue:

$ tar xzf telepathy-qt_0.9.6.1.orig.tar.gz
$ cd telepathy-qt_0.9.6.1
$ [ -d debian ] && echo "warning: debian/ already exists!"
$ cp -r ../telepathy-qt-debian/debian .
$ dpkg-buildpackage -rfakeroot -i.* -j13 -us -uc
$ cd ..
$ ls *.deb

Now you should see a list of libtelepathy-qt* and telepathy-qt* .deb packages. You just have to install a few more packages:

$ dpkg -i libtelepathy-qt4-2_0.9.6.1-2_amd64.deb libtelepathy-qt4-dev_0.9.6.1-2_amd64.deb libtelepathy-qt4-farstream2_0.9.6.1-2_amd64.deb

After that you have the necessary packages to install reSIProcate.

$ dpkg -l | grep telepathy-qt

Should return you something like this:




Telepathy framework – Qt 4 library




Qt 4 Telepathy library (headers and static library)




Telepathy/Farsight integration – Qt 4 library


After installing telepathy-qt properly you would be able to configure reSIProcate.

Make sure you have added backports to your /etc/apt/sources.list file

$ git clone
$ cd resiprocate
$ apt-get install libpq-dev dh-autoreconf
$ apt-get build-dep resiprocate
$ apt-get install -t jessie-backports libradcli-dev
$ ./build/
$ make

And then you are done!
