PyCon India 2019 Experience

What an experience it was! This was my second time attending PyCon India and third time attending a Python Conference. I have been a part of the organising team of PyConf Hyderabad 2017 and PyCon India 2018 (Hyderabad). Each time it has been a fulfilling experience and numerous takeaways and new bonds of friendship made. I haven’t blogged about my experiences in past conferences. So this will be my first blog post regarding my Conference experience.

The last 2 times I had attended Conferences close to where I was presently living. This time PyCon India was held in its 11th Edition at Chennai. Being organiser in past Conferences I knew about the wonderful experiences that I was involved, so I decided to be part of the Volunteering team for this year’s PyCon. I was eagerly waiting for the event from when it was announced. PyCon had become a mandatory event for me now, where I get to meet old friends and make new ones.

Day 0

I reached Chennai on 11th Oct night, before the Conference to help out with volunteer activities. I went straight to the Conference venue at Chennai Trade Centre where many volunteers had gathered for helping out with Pre Conference activities and goodie bag packing. This is like a fun event where we introduce ourselves and assign tasks for the upcoming days. I met HydPy folks – Ram, Murthy, Gokul; Dgplug friends – Rayan, Devesh, Chandan, Bhavin and many more friends whom I met at last PyCon. Chandan was co-ordinating the Volunteer team. I also met Vijay, Naren and folks from Chennaipy who were the organisers this year. After Dinner we started packing the goodies bags and sorting Attendee ID cards and getting prepared for the big day. It was almost 2 am when we left the venue to our hotel. Unfortunately my Oyo booking was cancelled, thanks to Murthy who shared his accommodation for the night.

Day 1

It was the first day of the Conference. I reached the venue around 8 am, there were already people coming in for registration. So I sat at the Registration Desk to help with Registration. I met with Kuntal (@hellozee) from Dgplug and Rayan who helped with the Registrations. Within no time there was a big queue of people. After sometime when the crowd lessened I went for Breakfast where I met Chirag, who came for the day. We discussed regarding the Upcoming PyConf Hyderabad 2019 event. After that I met all folks from HydPy who had come up for the conference. Here’s our group photo

After that I went to attend Pradyun‘s talk on Python Packaging . It was a really insightful talk explaining the pip ecosystem. Soon after the talk I started going around Sponsor booths to know more about their business and also to solve the puzzles they were gibing out to get some goodies 🙂 This year PyCon India had a long list of Sponsors – 41 of them ! Kudos to PyCon India team!

Post lunch there was Poster Presentation Scheduled where I was going to talk about HydPy Community. Also as I was a volunteer helped in setting up for Poster sessions as well. Folks from HydPy were also there, we also talked about our upcoming conference – PyConf Hyderabad on Dec 7-8. The day got over with ASL Devi‘s Keynote regarding Bridging gender gap in tech. It was an eye opening talk on different gender stereotypes and the unconscious biases that we have in our mind and how we can overcome this together. After that we had Volunteer’s meet to retrospect and discuss feedback regarding the day. The day ended with the Volunteer and Speakers dinner.

Day 2

My Day started again in the registration desk where I sat down to help with Lightning Talk registration and giving out ID cards to the attendees who missed taking it last day. Shortly after I went to the First Keynote of the day by Ines Montani . The Talk was titled Let Them Write Code . The Talk covered some best practices in development and coding, her Lessons from Open Source and much more. We had the Dgplug Staircase Meeting today which is a customary meeting that we have in PyCon India each other where we meet and greet people of Dgplug Community whom we have always seen in #dgplug IRC channel. It’s the time when we actually meet and talk to these people we see online. Kushal‘s absence was felt this time. Sayan was hosting this meeting and he discussed some important concerns regarding the community and the need for people interacting more in the IRC channel. After that he distributed Dgplug T-shirts which we had ordered before the Conference. We had the mandatory Dgplug group photo after that 🙂

I was helping out at the Helpdesk mostly rest of the day and interacting with people whom I met. There was the PyLadies booth just beside the Helpdesk where I talked to women from PyLadies Chennai community. They had a PyLadies Lunch last day and a Speed Mentoring Session to invite more Women in Tech. Finally we were up to the Final Keynote of the day by David Beazley . The Talk was titled – A Talk Near the Future of Python. After he started his Live Coding session in the Keynote the audience was simply going ga ga over his performance. He Live coded a Stack Machine which he later turnd into a Web Assembly compiler which played a Rocket Game at the end. He showed Python has a bright future by demonstrating the power of Python + Webassembly. This was The best Talk I have ever attended till date. He already published the screencast. Do have a look and amaze yourself. The thing that most impressed me most was his fearless stunt in front of 1200+ attendees and calmly handling the intermittent crashes and debugging them.

Finally PyCon India ended with Vijay‘s closing Address who was the Chair for this year’s PyCon. It was the end of the Conference after which we there was Workshop + Devsprints for next 2 days. At the end we had group photo with all the attendees.

PyCon India has been successful for the large pool of people who volunteer at the event and come from all parts of the country for the love for the Community. It has been a pleasure to work and interact with these amazing people. I met Noah this year who came all the way from Taiwan and volunteered from Day 0 for the event. It really amazes me to see the enthusiasm of the people for the Community.

Day 3

Oct 14-15 were Workshop + Devsprint Days. The venue was IIT Madras Research Park. I was also leaving tonight so I packed my bags and went to the venue in the morning. I started helping with the registrations for Workshops and Devsprints and guiding people to the respective rooms. Then I went to the Devsprint room to work on the Python Packaging Sprint which was hosted by Pradyun. I was eagerly waiting for that. I started with the setup and then working on a issue. After Lunch I found David Beazley in the venue so I quickly joined for a quick conversation with him. I asked the secret behind his Live coding stunt last day. He said he did roughly 15 iterations of the run, even spent 45 mins to debug an issue in one iteration. But yeah the fluency came over his 35 years of experience ! Also as he frequently took classes with group of students where he used to live code during his classes. It was a real pleasure to talk to him. After Lunch I continued to work on another issue from pip till the end of the day.

Finally it was time to say goodbye to friends and the awesome 3 days taking back lots of memories and experiences. PyCon India has become an event close to my heart now and it’s an event I don’t want to miss. See everyone again in next year 🙂


PyCon India has let me meet and communicate with people from all parts of world and domain. There is something to learn in each of these events. It’s An event by the Community. For the Community. My takeway this year was – Work, Interact and Share your experiences. You can always be a good at coding and be an excellent programmer, but unless you interact with more people and share your learning you cannot be a good person. Also Volunteer and give back to the Community. Volunteering requires time and effort, but its a gesture to give back to the Community and meeting people who are doing amazing work for the Community. The entire Open Source world largely revolves around people volunteering their time for the good of the Community. So even a small effort towards that can make a big change.

That’s all about my PyCon India 2019 experience . Do leave your comments ! And if this excites you do come next year to PyCon India 🙂

First BangPypers Meetup

BangPypers , the Bangalore Python User Group is one of the largest and oldest Python User Group in India. It has been running successfully for more than 10+ years. Most of the known faces in Indian Python Community have been a part of this meetup group at sometime or other.

After I moved to Bangalore I have been on the look out to attend the meetups but I missed it in the first 2 months since some work used to come by on the meetup days. Last Saturday, 21st September, I finally made time to attend my first BangPypers meetup.

The meetup was schedule at 10.30 am at Visa Technology Centre, Bagmane Tech Park. I decided to go by Cycling since I was also looking for a long ride in my Cycle for a while. But alas it took longer than expected owing to a wrong turn in my way.

The theme of this week was Design Thinking and it had 3 Talks scheduled. I reached around 11.15 am almost missing the first Talk which was a Design Patterns 101 Talk. The Speaker was almost in his closing notes. Nevertheless I found a place to seat in the almost full room.

I took out my phone to take notes and waited for the next talk which was on Design Pattern for distributed Architecture . The Talk covered various points on best practices related to distributed systems and tools and techniques to achieve them. Discussion revolved around Horizontal Scalability, Responsiveness, Security, Failure Handling, Centralised Logging, Metrics, Request Tracing, Health Checks, Configuration and Discovery. Since I never dealt with production level Python applications or Distributed systems the terms were quite new to me, few of them I encountered in past but didn’t quite fiddle in depth. I made a note of the discussion for future reference.

The last talk of the day was Organize your bookshelf using Micropython by Vinay Keerthi who was one of the Hosts at Visa, which is also a PyCon India 2019 accepted Talk. He made a LED book shelf organiser which would tell him the position of a book in the shelf by lighting LED array. He used Micropython on a NodeMcu in which he built a simple Flask app which would fetch data from a Postgresql database and store it in a queue which would send signals to the LED. I really liked the idea and it was a really hacky way to find a book. After his presentation I talked to him to get some pointers on starting my first Micropython project which I plan to do in the upcoming days.

After the session I talked to the organisers Anirudha and Abhiram with whom I shared my experiences at Hyderabad Python Community and also how they conduct BangPypers meetups. Visa had arranged lunch for the attendees so the discussion continued at the Lunch table where I got to talk with other attendees and interacted about the work they were doing. Bangalore has a vibrant developer community and there are many more communities like PyData, PyLadies which conduct regular meetups. PyLadies Bangalore are going to have a meetup on coming Saturday, September 28. Here is the announcment about the same.

At the end Vinay shared some more stories of his Hacks and experiences with tinkering with Micropython. And yeah here are some photos of the meetup I took

The thing that made the meetup nice was the great Venue and the Topics of the Talks. With the boom of ML/AI in Python Land having Talks that are unlike those, but most fundamental topics is good. Hope to attend future meetups as well!

Lastly I rode back home completing my first 20km streak in Cycle 😛

I also tweeted about the meetup after I returned home that day.

Takeways from the Meetup

  • Design Patterns in Python – Spend more time learning these.
  • Got to know about best practices in distributed system – Keep notes for futute projects.
  • Micropython getting started – Order some NodeMcu and get the hands dirty. TO DO: Read blogs regarding starter projects.

DevConf India 2019 experience

One month ago I attended DevConf India 2019. It was held from August 2-3 at Christ University, Bangalore. It was quite a while since I attended a conference, the last one being PyCon India 2018 . Due to my laziness in writing I have altogether missed writing my Conference experiences till now. This will be in fact my first Conference blog post. Now on I will make sure to write about each of the conferences I go.

I came to know about DevConf India last year when it was first held, from people in my developer circle. DevConf India is organised by Red Hat and has similar events in US and Czech Republic. Since I was in Bangalore this year I made sure I attend it after I saw the dates in Twitter. I registered as soon as I came to know about it.

Day 1

I mostly planned on meeting up with people and attend a few talks. I started at 8.30 am from my place and unfortunately missed the Keynote owing to a bad experience with a Bike Taxi service. I reached the Venue around 10 am and collected my Attendee badge and T-shirt. Then I headed towards the Keynote Session Hall where I met Naren from Chennaipy. I earlier met him at PyCon India 2018. It was nice catching up with him.

After having breakfast at the venue I headed to the Booth area where I met Chandan . I started visiting the booths asking questions about various projects like Fedora, Debian, CentOS. Shortly after I met up with some more familiar faces from DgplugSayan, Rayan , all of them I met during PyCon India last year. I expected a Dgplug staircase meeting at DevConf but unlike last year there were less attendees this time. After that we went for lunch at the Cafeteria where I met Ramki , Praveen and pjp . Few days earlier I was reading pjp’s tutorial regarding gcc and gdb from dpglug irc logs . It was nice to catch up with him in person. I was discussing with Sayan and Praveen about the initial days of dgplug at my college at NIT Durgapur, attending their first talk in 2013 when I had just joined my college.

After Lunch I decided to attend few talks. I attended a talk regarding Evolution of Containers – there I came across terms like Chroot, Cgroups, Namespaces , how the whole container ecosystem was born. I have been always been inquisitive about containers and though I haven’t really worked on containers before this talk really fascinated me to dive into the world of containers.

Then I attended a talk on What hurts people in Open Source Community . The talk helped to set my expectations right regarding contribution to a Open source project and Community.

After that I went to the Closing Keynote of the day shortly after which we went for evening snacks where we had more discussions over Coffee and Dosa – we noticed a item mentioning ‘Open Dosa’ over which we laughed a lot 😛 . And it was finally close of the day.

Day 2

I reached a little late to the venue and went straight to the talk that I didn’t want to miss. It was a Documentation BoF where speakers were discussing how to create effective documentation and tools for creating collaborative documentation. I came across User Story based documentation and tools of the trade like asciidoc and asciidoctor . I met Ladar Levison there during that session and talked with him regarding better project organisation. He gave me his business Card which mentioned Lavabit . Little did I know about him until I read this article which explained more about Lavabit and his role in Snowden’s secure email communication. But that was after this conference and I wished I could talk more about Privacy and Lavabit projects.

After that I went for lunch with Sayan, Chandan and Rayan where we chatted on lot of different stuff on open source, food and conferences. After Lunch I went to attend Sinny‘s talk on Fedora CoreOS whom Sayan introduced last day.

Finally it was nearing the end of the day. I went to attend the closing keynote by Jered Floyd and sat beside Christian Heimes from Red Hat who was sharing anecdotes from his travel experiences.

Notes from the Conference

I made few notes that I would like to share from my experience at the Conference and also as a note to me for future Conferences

  • Try to search about people you meet so that you can know more about them. You may not know everything about the person you are talking with. But actually the person can be a mine of knowledge. Ask for the person’s email/Twitter so that you can follow up on email or Twitter after the conference.
  • It’s always good to prepare some questions if you are likely to meet a person you met/knew online. You have the opportunity to talk face to face and ask about the projects the person works on. You can even do that within the conference when you are free.
  • When you attend a Talk ask good questions that can start a conversation. Usually people take a interest in following up after the Talk with you and you get to talk to more people.
  • It’s always good to be Speaker at the Conference. That way there is higher chances that you can start a conversation with people you don’t know and meeting for the first time. This is something that I really need to work on and hopefully I will be able to submit a talk in the next Conference I attend.
  • When going for Lunch tag along with a group so that you get meet more people. If you are an introvert this really works well as you can meet friends of friends and you can interact much easily!

And yes don’t forget to take pictures 🙂 It really bring memories. It may sound weird but this is something I really forget every time I meet up with people and later wait for Conference photos.

Modified Views for – Expanded Q & A Project

The end of the eleventh week in GSoC 2016 and when I look back I am amazed to see the amount of contribution that I made to plots2. For the last couple of weeks I  have been working on designing the interface for some pages, mainly the changes due to the Q & A system. Here are what I have been working on till now

  1. Add a Recently Answered tab in questions landing page that lists out the recently answered questions
  2. Add Q & A to user Profile that would list the questions asked and answered by any user
  3. Create a a distinct sidebar for questions
  4. Add a tag based sort functionality for questions. This would enable filtering questions based on tags
  5. Add a separate question tab in tags page. Tags page contained research notes, wiki and maps earlier
  6. Make it easier to search and ask questions from the questions page by improving the Search/Ask question field that I made earlier.
  7. Finally add links for Questions page in the website header and also put links to Question page and Ask question page in various pages like the dashboard, tags page etc.

This is going to be long PR and I am still working on it; it is nearly completed. Just some little design changes and modifications are needed.

Apart from these there were some important issues that I had to take care while making these changes. I had to distinguish between research notes and questions since questions in plots2 were actually notes marked with a question:topic power tag. So I had to list out research note and questions separately. I made two methods .research_notes() and .questions() in the DrupalNode model that would extract research_notes and questions separately.

Apart from these there were many small design changes that I had to make alongside. Here are some of the screenshots of the pages. They are likely to  be changed in future.

Here is how the questions page looks now when you go to the /questions url


Here is how the content of the questions section in profile page would look. You can see this in the /profile/:username url


And here is how the questions will be listed in the /tags/:tagname url

Cloud9 Deployment

Well it’s been a week while the GSoC 2016 application deadline is over and waiting for results is frustrating. So let me share some awesome facts I got to know while I contributed to plots2.

Cloud9 IDE

Cloud9 is an awesome online IDE that comes preloaded with many build packs and supports over 100 languages and frameworks. It comes with a built-in terminal and debian based package manager. Basically it has Ubuntu installed at its root. So if you wan’t to avoid the hassle of installing many frameworks in your machine Cloud9 is your best choice. It also has support for many git hosting websites like Github and Bitbucket so you can directly sync in your code repository from Github in your Cloud9 workspace.The code editor has a look of Sublime text.

Deploying your Project on Cloud9

Deploying your Project on Cloud9 is as simple as anything. If you are working on any web based application (like Ruby on Rails) you can also directly see your application running in a temporary url provided by cloud9. I am telling how I deployed it for plots2 repository.

  1. Visit Cloud9 and login with the Github Button provided you have a Github account.
  2. Create a new workspace by Clicking Create Workspace button. Name your workspace and give it a description or optionally (as I did)  if you have a Github repository enter the URL in the “Clone from Git or Mercurial URL” field, and it will clone it from your Github repository. Then click Create Workspace.
  3. In the terminal at the bottom of the page, type . ./
    and press enter
  4. Enter your username when prompted, and run rails s -b $IP -p $PORT
  5. Yay! You have the app running! Go to the URL shown.

They did a clever task by writing all the pre running commands on a installation script. That’s what the file does. It makes it easier for beginners to deploy it very easily. You can also write a installation script yourself by writing the commands for installing or setting up any dependencies for your project.That gives it a much cleaner look.Here is my  Cloud9 deployment of plots2.

So you see how simple it is! Hope you enjoyed!


Beginning My Journey as an Open Source Developer

Open source and Open learning has fascinated me since I came to know about it. The feeling of being part of a big software by contributing even a single line for it inspires me to become a Open Source developer some day. So learning of Git became indispensable and there has been a lot of people in my College preaching Open Source  so I had quite some idea on where to start from. So the easiest step for me was to open a Github account and learn Git at the earliest. Soon it was clear to me that learning  Git was just the beginning. Contributing to Open Source was way beyond that. You had to read the code, understand it, understand the bugs and issues and the biggest part “Attempt to solve it!”. And as the saying goes

Try and try until you succeed!

Soon I developed fascination for Ruby on Rails while working for a CAT Forum for my College Club in the last Summer. It is an web application framework based on MVC model. It was the very first time I practically worked using Git and contributed to Open Source in Github. Though I had just scratched the surface and it is quite a long way before I could actually become an Open Source developer.

My next step towards achieving this is Google Summer of Code 2016 which is the most prestigious worldwide internship Program organised by Google for supporting Open Source.Recently I have been contributing to on its plots2 Repository on Github. I had my very first PR merged in and I am really excited to work on it further. Hoping to see this as my  GSoC Project.
