JSFoo 2014

JavaScript as the centerpiece of a complex web stack

In 2011, Node.js put JavaScript firmly in the backend, making JavaScript developers productive at both ends of the stack, and making it possible for business logic to finally be moved into JavaScript.

In 2012, AngularJS made us think about moving business logic completely into the client-side as an actually sensible idea. Meteor give that idea two thumbs up.

In 2013, we went wild thinking of all the possibilities. JavaScript phones! Robots!

In 2014, it’s time for some sobering up. The backends we built over a decade in Ruby and Python aren’t going away. New languages like Go and Hack are tantalising us with new possibilities. Our applications are increasingly distributed, often involving third party APIs. In such a scenario, where does your business logic reside?

In 2014, JavaScript is no longer a toothless child or a rebellious teenager that wants to do everything itself. JSFoo 2014 is about working with JavaScript as the centerpiece of a complex web stack.


This year’s edition spans four days, with two days of workshops and two days of conference. All days feature a single track. We invite proposals for:

  • Full-length 40 minute talks
  • A crisp 15-minute presentation
  • Sponsored sessions, 40 minute duration
  • Flash talks of 5 minutes duration. Submissions for flash talks will be accepted during the event
  • Three hour workshops where everybody gets their laptop out and follows along

Criteria to submit

You must be a practising web developer or designer, and must be able to show how your own work has advanced the state of the web in the past year. You are expected to present original work that your peers — this event’s audience — recognise as being notable enough to deserve a stage.

If you are excited about someone’s work and believe it deserves wider recognition, we recommend you contact them and ask them to submit a proposal.

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.

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 editorial panel build a strong line-up for the event.

There is only one speaker per session. Entry is free for selected speakers. HasGeek will cover your travel to and accommodation in Bangalore from anywhere in the world for speakers delivering full sessions (30 minutes or longer). 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.

Commitment to Open Source

HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, 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.

Javascript and mathematical computing across servers and clients

Submitted Aug 5, 2014

The primary objective of this session is to showcase Javascript as a viable language for mathematical and scientific computing. We’re going to explore some of the best libraries out there for symbolic math, statistics, set theory, as well as machine and deep learning, as well as talk about how tools like NaCl and d3.js, can be used for mathematical models that can run in the browser, and on the server.


  1. We’ll first start off with an introduction to why many of the current languages used for math and science, have issues - non-asynchronous natures, server-based, and so on.
  2. We’re going to move on to some really good and extensive libraries, on symbolic computation, statistics, machine and deep learning and set theory. We’ll talk about the problems they’re typically meant for and used in, and we’ll check out some basic examples.
  3. We’re now going to go deeper into the rabbit hole, and discuss how one can run mathematical models and expose them over APIs using Node and Express; how these APIs can then be consumed using d3.js for visualizing results; running mathematical models inside Google’s Native Client, or on embedded hardware using Cylon.js; oh, and we might throw in some WebGL for fun!


Pen and paper, if you like taking notes. Tablets work too.

Speaker bio

I’m Rudraksh, and I specialize in computational math. I’ve got varied experience in using math and data science for journalism, events management as well as ed-tech and social media startups. Currently, I’m working on a startup called MathHarbor, where we’re building a cloud platform and hub for computational math and stats using open-source languages and toolsets.
