Promise to test it!

Speaker:

Properly testing a stateful system – like a typical web api – is hard. Doing it in JavaScript is even harder, because semantics easily drown in callback hell. Most folks out there are starting to use promises to solve it, or at least imagining so. Unfortunately very few developers have understood how to leverage this […]

Frameworkless JavaScript with npm and browserify

Speaker:

I don’t tend to use frameworks, as a personal preference I like feature driven, organic code bases. This often leads to questions about structure and organisation. Come along to find out how simple life can be without frameworks, and what the world looks like when you’re not limited by the chains they bring.

You have ruined JS

Speaker:

It’s time to have a conversation about JavaScript. You see, I think you’re ruining it. You with your frameworks and your layers of indirection and directives. You with your angulars and your embers and your backbones and your model view controllers. So we’re going to have this conversation and see if we can’t straighten a […]

Javascript, metaprogramming, and you

Speaker:

We all know that Javascript is powerful but it can be a really terrible language when misused. Moreover, it lacks several advanced features that are taken forgranted in other languages.One technique that is always overlooked is metaprogramming: hystorically only lisp dialects support it properly, and programmers regularly underestimate its power.In the spirit of Coffeescript, Typescript, Clojurescript and other similar projects […]

Flow-Based Programming for JavaScript

Speaker:

NoFlo is a flow-based programming environment for JavaScript. Originally built for Node.js systems automation, it can also be used for developing full-stack applications from the browser to microcontrollers like Arduino. With NoFlo developers build their applications by wiring data streams together between different pre-built or custom components. The NoFlo environment is fully browser-based and can […]

Make your Backbone applications dance!

Speaker:

Building Backbone applications quickly became a de-facto standard, though we can’t really define it as framework but rather just as foundation to create other frameworks. If you like Backbone, you’ll fall in love with Marionette, the best application library to create large scale Javascript applications. Nicholas will explain the framework, show examples and talk about […]

AngularJs for Mobile

Speaker:

You should always think mobile first when you work on web stuff. Your ui should care about touch events, multi-touch and mouse as well. Mobile devices are not powerful as desktop one, you should take care of performance and download time. Maybe is better to have an optimized version for mobile users. How can you […]

Agile CSS development with Compass/SASS

Speaker:

CSS is not a complete language, it misses variables, functions, nesting, partials and math. SASS makes easy to create CSS for complex sites. Compass allows you to do easy spriting, easier debugging, and more. In this speech I’ll show you the main features of SASS, Compass, how to install it, and why you will never […]

Firefox OS: Unicorns and Rainbows

Speaker:

The past years there has been some heavy debate over web vs. native for mobile applications. But to be honest, it has never been a fair game as the web was lacking crucial functionality. No access to sensors, not available offline. Essentially: the mobile web is broken. Luckily if something is broken, we can fix […]

Performance Testing Crash Course

Speaker:

The performance of your application affects your business more than you might think. Top engineering organizations think of performance not as a nice-to-have, but as a crucial feature of their product. Those organizations understand that performance has a direct impact on user experience and, ultimately, their bottom line. Unfortunately, most engineering teams do not regularly […]

MongoDB, Node.js and You

Speaker:

Node.js, MongoDB, Express, AngularJS, how does this all tie together? Mitch walks you through the creation of an example app to demonstrate how to take advantage of Node.js and MongoDB, while leveraging features from AngularJS and Express for rapid prototyping that can survive a production launch.

The strange world of Javascript and all its little asynchronous beasts

Speaker:

Javascript is a wonderland populated by all kinds of exotic beasts. Callbacks, events, promises, functional programming, reactive programming, streams, generators are all part of this incredible asynchronous bestiary. We’re talking of insidious or even ferocious things, a great danger to the unwary programmer. Let’s look at them, learn from them, tame them and finally put […]

The fourth dimension

Speaker:

In the spacetime model, the fourth dimension is time. In this talk I will show how to transform and manipulate events happening in different moments in time the same way that we transform Arrays or normal sequences, by using the power of Functional Reactive Programming. This will allow us to unite synchronous and asynchronous code […]

Monads, Promises, and Reactive Metaprogramming

Speaker:

Prerequisites: having followed Federico Galassi’s or Sergi Mansilla’s talk (either is fine), or just having an idea on what rx.js does. Javascript programmers are often struggling with asynchronous control flows. It does not matter if the sources of time warping are AJAX requests, the nodejs event loop, or a simple flow of events from the DOM: the result regularly […]

React.js – The smart, brute force DOM re-rendering revolution

Speaker:

When data changes, or users interact with our application, we have to update parts of our DOM. Set a class, remove a node, or update the text of an element. This is complicated and needs clever, error-prone code. With React.js the Facebook team introduces a revolutionary brute-force solution to this problem: Simply re-render all your page whenever anything changes. This […]

Further Adventures of Hyperaudio

Algorithms are bioluminescent creatures of the deep sea

Speaker:

Quicksort. Heapsort. Bubblesort. Sorting algorithms are computational processes used to organize elements of a sequence in a certain order. In the last few months I have tried to understand and transform the data left behind sorting algorithms into visual forms that could help highlight the unique characteristics of each algorithm and find hidden patterns. SORTING […]

AngularJS: The Good, The Bad and The Ugly

Speaker:

The popularity of AngularJS has exploded over the past 12 months with over 20.000 starts on their Github page. Its goal to make web application development easy appeals to many developers. Indeed, seeing the demos of two-way data binding are impressive. I have written my own MVC frameworks, worked on custom MVC frameworks and used […]

If You Like It Then You Should Have Put A Test On It: A Comparison of Front-End Acceptance Testing Frameworks

Speaker:

Everyone knows that acceptance testing is important, as ultimately the biggest test of your code is “does it do what its supposed to?”. But few people enjoy writing acceptance tests. Several front-end acceptance testing frameworks (intern, dalek and nightwatch) have emerged in the past year, all designed to help you write clear, expressive, javascript-based tests […]

Out of the sandbox: developing native Desktop apps

Speaker:

We build web apps that runs on browser and server-side apps on Node.JS, but what’s about native Desktop applications? In this talk I will introduce node-webkit: an app runtime based on Chromium + Node.JS, you can use to build Desktop apps with JS and HTML, with no browser’s limitations like file-system calls or running native […]

Automated CSS-testing with JavaScript – Not just a myth
