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.

A/B Testing Platform and when is the result significant
Submitted Sep 10, 2012
Section:

Technical level:
Beginner
Session type:
Lecture
In this talk I will motivate the need for an experimentation platform. I shall discuss the various modules of an experimentation platform and share how to go about designing or building such a platform. I shall also work on the basic mathematics to develop the intuition (not just share the final formula) of when a result is statistically significant.
Outline
The greatest tool for rapid innovation is rapid experimentation. The true crystal ball for all experiments is the greatest designer of all - the internet. Actions of people on your site tell you what your audience desires or even craves.
In an A/B testing platform we require:
- Cohort-aware bucketing
- Stickiness beyond a session and translated to an user
- Ability to fix the percentage of users who will see an experiment e.g. 1%
- Determining statistical significance of results (Gaussian error and beyond)
- Ability to rapidly deploy the changes to production
In this talk we shall talk about discuss all 5 layers and include basic mathematics to develop the intuition behind the formulae for statistical significance.
I will also discuss how to extend this beyond
Requirements
Basic understanding and knowledge of the Web world
