Demystifying WebGL

The modern web is tearing down the borders of the browser window and allows us to create so much more than just another website.

This talk is a beginner-friendly introduction into how to leverage WebGL to build 2D and 3D applications that make optimal use of the GPU to produce visual effects and interactive 3D spaces right in the browser - no plugins needed.

The talk covers the basics of the GPU pipeline, what Shaders are and how to program the GPU with GLSL as well as giving a walkthrough to a full WebGL application using Three.js.

Angular 2, Demystified

Angular 2 aims to be the next major frontend framework, attempting to improve where the original AngularJS failed while retaining the parts that were great. But is it production-ready yet? And why should you use this over, say, React with Redux? At NPR, we were early adopters of Angular 2, building and launching a production app while the framework was still in beta, so we took a big risk but we think it’s paid off. Come find out what we love about it, what gave us the most trouble when we were getting started, and why we think you should consider using it for your next project.

Modern Websites for the Modern Web

It seems like new APIs for the web are released every week. It would be cool to be able to use them, but if you need to make websites for the average user, you won’t be able to use them for years - right? Wrong. I will go over how creating feature rich and super fast front end applications, integrating over a dozen cutting edge web features, all while supporting even the oldest of web clients. If you want to see a 100% client side offline enabled application work in every browser to Mosiac, and even be ported to a command line GUI (yes GUI), come check it out!

Parashuram is a front end developer and web performance enthusiast and author of tools like browser-perf. He has created the Web Worker based render for ReactJS and runs “science-like” experiments to explore ways to make web applications faster.

He is also an open source contributor, a committer in the Apache Cordova project and works as a Program Manager in Microsoft

He wrote the ReactJS implementation of Webworkers. He also runs performance analysis of common web frameworks like Angular and React, and has been running experiments showing how web workers always increase the perf of existing frameworks.

Rise of the Web Workers

Modern web applications are awesome. And complicated. The Javascript libraries that power them today do a lot of work to abstract out the hard parts. Whether using constructs like Virtual DOM, or fancy change detection algorithms, the amount of work that the Javascript library does is only increasing.

Unfortunately, all this work now competes for the same resources that the browser needs, to do things like render a page, or apply styles. In many cases, this makes the browser slow, preventing the web application from attaining its full, smooth experience.

Web workers have been in the browser for a while, but they have mostly been used for engaging demos like adding mustaches in a cat video :)

In this talk, we will explore how mainstream Javascript libraries like React or Angular use Web Workers to get great performance. We will look at quantitative numbers from hundreds of test runs that conclusively show how Web Workers can make apps faster. Finally, we will also look at practical examples to convert existing examples, and the potential limitations of this approach.

"fifty points at random"

When does process become art? When do tools become collaborators? Let’s explore the world of procedural art – both analog and digital – through the wall drawing of Sol LeWitt. This talk teaches how to make art in the style of LeWitt’s wall drawings with CSS and JavaScript, and along the way provides some insight into the history of procedural art, the nature of randomness, and how tools and algorithms for creating art lead to new forms of collaboration.

Mike North is the CTO of Levanto Financial, and before I started working here, I was the UI Architect of Yahoo’s Ads and Data division. While there, I was the driving force to get the company off of antiquated frameworks like YUI (and a generally fragmented ecosystem), onto modern technologies like Ember.js and React. I’m an avid open source contributor in the JavaScript community, and am cracking into the Elixir community more and more. Earlier this year, my in-depth video course on Ember.js course went live on

Delightful UX for Distributed Systems

Long-running processes, concurrent editing, operations requiring user intervention, and integration with unreliable external services present new challenges to building web UIs. Building a pleasurable, robust and reliable user experience is more far more challenging when critical pieces of your workflow are out of your direct control.

We’ll begin by describing what a distributed system is, and highlight the new challenges that it presents, compared to a simple traditional system (i.e., background tasks, mobile web or offline use, hard dependencies on third-party services, etc…). Then, we’ll talk about some UI and system architecture patterns, using an Ember.js/Phoenix system as a case study.

Where possible and appropriate, I’ll show parts of a real-time distributed system (ember/phoenix), contrasting what the “non-distributed system” approach would have felt like to users against the “distributed system” approach.

As we go, we’ll begin to build a framework of questions that developers can ask themselves in order to address the challenges of high latency, loss of connectivity, the loss of access to a critical third-party service, and other problems often encountered when working with distributed systems.

Webpack: The Core Concepts

I had the opportunity to be introduced to using Webpack working at React shop, however as an AngularJS Fanboy and Apologist, I longed to bring the same brain-melting, experience to my ngApp. Problem was that I used, webpack, but never understood it. From automatically managing Bower, AMD, and NPM dependencies to code-splitting, minification, and source-mapping, I realized Webpack automagically handles all the hurdles I had ever encountered in my previous web projects. Together we will break down the core concepts and demystify this amazing tool.

My hope for you is that by the time we’re done, you’ll have set fire to every Gulpfile and Gruntfile you’ve ever written, destroy all those extra style and script tags in your browser, and give you the tools needed to make the best modern web apps, without sacrificing developer experience. Join me while we webpack ALL the things.

Redux, ngRedux, and Sagas: A Gentle Introduction for Angular Developers

You either have heard of Redux from the React crowd, or perhaps have learned a little functional programming, and are looking how to incorporate it into your Angular applications. Jesse will cover what Redux is, why it's helpful, how it's different from Flux/MobX, and how it's used in an Angular application. He'll also cover to use of Sagas, and how they make dealing with complicated asynchronous actions a lot easier to code if you're used to imperative/OOP languages, as well as testing them. Finally, he'll cover some of the pain points you can run into, refactoring strategies, and tooling setup needed.
