JSFoo 2012

It’s like kung fu with JavaScript and objects! All about building full size apps in JavaScript.

About JSFoo

JSFoo is India’s only national JavaScript conference series, with editions in Bangalore, Pune and Chennai. This year’s Bangalore edition is a flagship two day event.

Event theme

The theme for this second edition in Bangalore is JavaScript everywhere. Tell us how you’re pushing the limits of what can be done with JavaScript on the server, in embedded devices, and in its original home in the browser. If you have built something that is popular (even if proprietary), tell us the story of how you did it. Got graying hair? Help us younger folk attain the zen of JS. Tell us about best practices in code and in working style, of how to organize our files and how to assemble crack JS teams.

Commitment to open source

HasGeek believes in open source as the binding force of our community. If you are describing a piece of technology, we’d like it to be available under a permissive open source license.

If your software is commercially licensed or available under a combination of commercial and restrictive open source licenses (such as the various forms of the GPL), please consider picking up a sponsorship. We recognize that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a sponsored session.

Speaking submissions

You can submit a proposal to speak at JSFoo via the submission funnel below. Please describe your proposal in as much detail as possible. Detail is important if you’d like to be voted up into the schedule. In particular, we want to hear why you are the best person to be delivering a talk on your proposed topic.

Your submission will be up for public voting for up to a month before the event. For the final tally, we will only consider votes from ticket holders, as a way to ensure participants get exactly what they pay for.

This event also has a Program Committee of selected individuals from the community whose votes have additional weight, and whose charge is to help you refine your proposal and prepare it for the event. The Program Committee is responsible for ensuring that the final schedule meets the high quality standards that participants expect.

Making a funnel submission does not guarantee final selection. Selected speakers will get a free ticket to both days of the event (limited to one speaker per proposal). Proposers whose talks are not on the final schedule will be able to purchase tickets at the prevailing rate for the day on which they made their proposal.

Building massive horizontally scalable and fault tolerant system in Node.js - By Pavan Mishra & Akshay Surve

Submitted Aug 4, 2012

  • Thinking in Ad-ops scale
  • Building Node.js app with an expectation that it will fail on you
  • Eliminating SOFs and other commonly expected notions of server-side apps
  • Leveraging the AWS stack end-to-end - Route53 / ELB / EC2 / EBS / S3 / Cloudfront for horizontal scale
  • Performance hacks for Node.js app


Node.js is simply a breeze to work with but it’s also easy to go wrong with. We want to share our key learnings working on a massive horizontally scalable click and conversion tracking system powering our ad-tech startup DeltaX.

Apart from making Node.js work for you, we would also like to share the architecture and learnings from our system which leverages the cloud from end-to-end - Route53 / ELB / EC2 / EBS / S3 / Cloudfront.

Speaker bio

Pavan Mishra is a Python purist at heart and occasionally dabbles into other technologies. Node.js is not like love at first sight for him but he has grown fonder of it over a period of time. Is this what is called true love?

Akshay Surve has closely worked and consulted with startups ranging from social ventures (socialsync.org / ads4good.org) to consumer startups (ideeli.com). He is currently leading the development at DeltaX.com an advertising technology platform.
