JSFoo 2013

All about being creative with JavaScript

(Skip ahead to session proposals)

About JSFoo

JSFoo is India’s only national JavaScript conference. The first season of JSFoo featured editions in Bangalore, Pune and Chennai between Oct 2011 and Feb 2012. The second edition in Bangalore in Oct 2012 was based on the theme “JavaScript Everywhere” – featuring JavaScript on web servers, embedded in robots, as a cross-platform language for mobile, and in its original home, the browser.

##JSFoo 2013
The theme for JSFoo 2013 is original creations with JavaScript. Showcase innovative work done with JavaScript – if you have created something at work or outside your work commitments, with or without a business model in sight, something you’ve done for the love of seeing it come to life in front of your eyes, JSFoo is the place to talk about it!

Talks which demonstrate innovation at either a technical or “best practice” level will be given preference. Your creation does not necessarily have to be in production, but we will insist on it being something more significant than a cool ten-line function you came up with (unless that function allowed you to control sharks fitted with lasers or something).

We are also accepting high quality talk and workshop proposals on JS frameworks, libraries and tools. These proposals have to provide clear objectives and take-aways for practising JavaScript developers.

JSFoo 2013 is a single-track event. We invite proposals for:

  • full-length 40-minute proposal
  • a crisp 15-minute presentation
  • sponsored sessions, 40 minute duration
  • flash talks of 5 minutes duration. Submissions for flash talks will be opened one week before the event
  • Hands-on sessions ranging from two to six hours on JS libraries, frameworks and tools. These proposals will be categorized as workshops

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 2013 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. Provide links to previous talks and presentations you’ve done. This will help attendees and the programme committee in evaluating your proposal.
Making a funnel submission does not guarantee final selection.

##Selection Process
Voting is open to attendees who have purchased event tickets. If there is a proposal you find notable, please vote for it and leave a comment to initiate discussions. Your vote will be reflected immediately, but will be counted towards selections only if you purchase a ticket. Proposals will also be evaluated by a program committee consisting of:

Proposers must submit presentation drafts as part of the selection process to ensure that the talk is in line with the original proposal, and to help the program committee build a strong line-up for the event.

There is only one speaker per session. Attendance is free for selected speakers. HasGeek will cover your travel to and accommodation in Bangalore from anywhere in the world. As our budget is limited, we will prefer speakers from locations closer home, but will do our best to cover for anyone exceptional. If you are able to raise support for your trip, we will count that as speaker travel sponsorship.

If your proposal is not accepted, you can buy a ticket at the same rate as was available on the day you proposed. We’ll send you a code.

The program committee will announce the first round of selected proposals by 15th August and a second round by 2nd September. We will finalize the schedule by 7th September. The funnel will close on 25th August. The event is on 20th and 21st September 2013.

Who's Talking | Real-time Peer to Peer collaboration with JS and HTML5

Submitted Jul 26, 2013

JavaScript is everywhere

Even in the new HTML5 APIs.

HTML5 has introduced WebRTC and the pioneers of the Web (Mozilla, Google, etc.) are doing a lot of R&D in open-source ventures related to WebRTC in HTML5.

This talk stands out from trivial old HTML5 stuff and focuses on using JavaScript for building real-time collaborative apps with new features, something that really replaces Desktop / Native apps.


HTML5 has been upped with WebRTC features that allow us to create a collaboration environment, enabling Real-time Webcam Video sharing, File-transfers, Screen-sharing, Audio recording, etc.

This talk focuses on ways to use JS, HTML and CSS, with new features to build simple yet cool apps, that can replace other desktop apps and browser plugins which have dominated the communication realm on internet.

Developers need to know the new JavaScript APIs introduced in the browser, before things go too far and you have wrappers around everything enveloping the real-stuff.

Important topics:

  1. What is WebRTC and how it works, the architecture and implementation.
  2. New HTML5 APIs in JavaScript that allow accessing Webcam feeds, establishing Data Channels, etc.
  3. The Signaling, Call offers, Call Answers, Reception, STUN & TURN servers, etc.
  4. Peer to Peer transfers of live video streams, arbitrary data, screen-sharing etc.
  5. Creating GIF Animations from recorded video - something personally attempted.
  6. Duplex Server Client Signaling using socket.io (backend) and HTML5 WebSockets (in Browser).
  7. How this can be converted in a Single browser app, which alone can replace native OS apps like Skype, DropBox, Microsoft Linc, Teamviewer, etc.
  8. Some cool Demos and stuff already brewing on internet.
  9. Ways to contribute to WebRTC project.

Above points are randomly put for an overview - the content will be much well organized from a learning perspective.

Important Useful Links:



  1. Interest in moving the Web forward with HTML5
  2. Respect for Mozilla, Google, Adobe and others who do so.
  3. Selected Browsers (Chrome 30 dev, Chrome 28 stable and Mozilla nightly only). Browse happy (browsehappy.com) won’t suffice.
  4. May be a code editor if you want to follow along. (preferred Sublime Text 2, Adobe Brackets)

Speaker bio

I am a Mathematics and Physics freak who entered the Web realm while the age of old dynamic web-sites was transforming to modern web-apps.
I have built awesome web products while working in companies like Adobe Systems, WalmartLabs and Amazon, using frameworks like Angular JS & Backbone

Having a keen interest in Artificial Intelligence, I get thrilled when AI is used for human interaction - which explains my love for “JavaScript and logic” to create interactive and intuitive UI, data visualizations and presentations, etc.

I naturally get excited when its about JavaScript.
