Web Application Design from a Developer's perspective

Poorly designed web applications fail to serve both the business and the users, leading to a unnecessary costs, and frustrated customers. By keeping the user in mind, and following a few simple guidelines, you can make huge leaps in the way your users interact with your applications.

In this session, we will focus on the enterprise - where the user-base is known and fairly consistent, but typically where user interface and interaction are not the top most priorities. We will discuss some rules for good design, look at a few simple design elements that can make your web apps shine, and your users rejoice.

Creating Websites using Noir

Think Clojure is only for the back-end functional geeks? Think again. Noir is a web application framework written in Clojure.

In this talk we will see how we can create a simple site using Noir, and with Heroku's support for Clojure, deploy and run it in the cloud.

Dive into D3.js

A picture is indeed a thousand words. Often, your users are better served if they are offered a visual representation of data than reams and reams of tables. Most JavaScript graphing libraries offer a DSL to create graphs, but can prove to be constricting if you are attempting to do something outside the original intent. D3.js, instead offers you an API to work with "data documents" - with powerful data manipulation capabilities, and visualization components. Furthermore, it leverages SVG rather than the Canvas element, allowing you to unleash the full power of CSS3 to style your latest creation.

In this session we will take a dive in D3. We will look into how D3 offers no new constructs for visualization, but rather lets you leverage well known web standard technologies such as HTML and CSS. We will see how to "think in joins", and use D3 along with SVG to create a animated bar chart.

Once you understand how D3 works, and how to use D3's APIs to create and manipulate the DOM, along with scales and axes you will be well on your way to creating your first visualization.

On Prototypal Inheritance

You are a JavaScript developer who has gotten past writing one-off scripts on pages and wants to leverage the true power of the language. You have tasted the power of objects, and inheritance in Java, and hope to put the same to work for you in JavaScript.

This talk will aim to explain how inheritance works in JavaScript, albeit in the prototypal world rather than the "class"ical world. We will see how to create your own inheritance trees, and create instances that are born with a predefined set of behaviors.
