Global Android Hackathon 2012 – Event Summary – GTUG Chennai

Hello readers,

Last weekend I have organised a Global Android Hackathon in Chennai at CollabNet.

Global … what?

The Global Android Dev Camp is a collection of events that takes place from February 17th to 19th, 2012. Android developers from all over the world come together at more than 30 locations and hack for 48 hours – nonstop!

Ah! okay, what happened that day?

Let me summarize the two days event happened here @ GTUG Chennai.

The event was held at CollabNet Software pvt. limited, Chennai. We had around 55 hackers gathered in training hall scaling from beginners to intermediate in Android development platform. Few already came as a team. The event started at 10.30AM IST.

Day 1 started with a self-intro to make everyone get to know each other and socialize. Following that, we had teams explaining their application prototype. They disclosed their project requirements and interested ones have volunteered to join their teams. We have finalized 13 teams working on 13 different apps.

Following that, we had Patrick, a Google Apps consultant from meghaITConsulting giving a lightning talk covering a glimpse about the hackathon event.

Next, we had Issac Wessley from Technogemsinc volunteering himself to give a talk on Android UI designing and the best practices to be followed with respect to layout and UI designing.

Post lunch, we had Santhosh from Samgha giving a glimpse about Android’s basics explaining the architecture and the best practices to be followed for beginners while coding.

Day 2 – Participants continued hacking throughout the day till 4PM. Then we had a Hangout with Googlers and the rest of Indian GTUGers who organised this DevCamp in their respective places. As we didn’t have much time, we saw a few demonstration from GTUG Bangalore.

Following that, One of the team members representing their team presented their application and demonstrated their application in their emulator.

Sriram from CollabNet and myself as juries, rated the applications based on 4 criteria (Innovation | project completion | originality | design). Out of 11 completed apps, we have picked the apps that scored the highest.

After announcing the winners, we had feedback and group photo session. We got an overall rating of 4.5/5 which is indeed the best score that I have ever thought. Few volunteers agreed to give a video feedback about the event, which will be posted soon.

Had one of the best weekends I have ever had.

How about the event feedback?

We got an extremely satisfying feedback from the participants. Post the event, we had video feedback from attendees

Did you get any sponsor for this event ?

Ofcourse, yes. I thank CollabNet for sponsoring the Venue. Google for bearing food expenses and Symposiumz for popularizing the event online among students. I also thank one and all who were supportive to me behind the scene.

I had one of the best weekends I have ever had with a satisfaction of conducting a grand event successfully. I enjoyed every bit of it. I’m sure every participants have felt it useful.

The only thing I have missed is to update media about this event. I’m sure few of our apps would have got into the local newspapers.. like how an app in the Bangalore event has been featured here. Congrats to the team.


I wish to attend future GTUG events. How will I be notified ?

Planning before the event
Initially, A month before, I formed a team of enthusiastic contributors for organizing this event and started framing the content and topics and segregated those topics to each individuals feels interested and good at it.
Then, We have put up on the site and sent about it to various mailing lists and to the whole college over SMS and thereby willing students registers in online.
After Approval from our college, we have started preparing brochures, posters, ID Cards, Banners, Certificates to publicize the event.
We have also brought chief guest to give away a guest lecture on topics based on Security and Technologies..
  • As we have the habit of organising Summer Camp and winter camp every semester holidays as a routine, we haven’t found it difficult in executing it and thus made this event a grand success too! with a turnout of 110 attendees.
  • Also, we have full support from our College administration and staffs in promoting student activities and in fact, that is the main aspect for success.
  • Myself, being a FOSS Enthusiast, have scheduled collaboratively with Open Source User Group to introduce students to Open Source technologies as well
  • We have collected a registration fees of Rs.150/- (A very meager amount) to provide them few giveaways like resource DVD, Notepad, pen, ID Card, Snacks, Certifs, etc !
  • Most importantly, we have offered participation certificate for all the attendees as a vote of honor and also to encourage them to attend such events and meetings regularly
  • Collected feedbacks in Google spreadsheet at the end of every day to know what every individuals feels and in turn, we got a heavy positive response !
  • The same strength of students were there till the last day of the camp !

Birth of Google Technology User Group Madurai

Hello everyone, Hope you read my previous post “Birth of Open Source User Group in KLNCIT”, if not, read it and come here back as this is actually a part of it  🙂

While searching about user groups and Communities, I suddenly found Google Technology User Group to be catchy and started to read thoroughly with my eyes popping out of anxiety! . . I was seriously longing for some organisation to recognize my activities and I hardly found anything successful . Out of  frustration, I just registered for a chapter in Madurai  for name sake.

It was Jan 9, while thinking to plan for starting up an OSUG in our College , to my surprise I got  a mail from Steph (Google) stating that GTUG Madurai was approved followed by few other Instructions.. , I was Jaw stuck for a moment, I started jumping till I hit the ceiling 😛 . I

Soon I started creating a logo, site for it followed by mailing lists, social network links and started planning for my first event to be a grand one !

I ended up inaugurating GTUG along with OSUG in 17th March 2010 @ our College  and thus my contribution towards Google Technologies begins 😉

I started learning things of my own to meet my needs .

Got to know about hell a lot of  new stuffs about Google’s Developer Technologies and its contribution towards Open Source 🙂

Now, I feel Glad and honoured to have this Manager privilege for my Madurai Chapter. 😉

Will promote whenever I get a chance to speak . . Got so many plans pipelined to do in forthcoming days !
