From Software to Hard ware: How Do I Track My Cat with JavaScript.

In the era of Internet of Things, connecting things to the mobile devices and web is becoming ubiquitous. You can control room light using your mobile phone. You can monitor your heart rate and weight on browser. JavaScript engineers like you already have skills to prototype ideas to build software, so why not hardware too.

Tomomi Imura, a front-end engineer with no background in electrical engineering, shares how she got started with hardware hacking with JavaScript, also talks about her recent fun project, KittyCam, a Raspberry Pi camera with cat facial detection to see when her cat is eating while being away from home.

Cutting-Edge Responsive Web Design

With HTTP/2, Service Workers, Responsive Images, Flexbox, SVG, WAI-ARIA roles and Font Loading API now available in browsers, we all are still trying to figure out just the right strategy for designing and building responsive websites efficiently. We want to use all of these technologies and smart processes like atomic design, but how can we use them efficiently, and how do we achieve it within a reasonable amount of time

In this talk, Vitaly Friedman, will be looking into a strategy for crafting fast, resilient and flexible responsive design systems by utilizing all of those wonderful shiny web technologies we have available today. We'll also talk about dealing with legacy browsers and will cover a few dirty little techniques that might ensure that your responsive websites will stay relevant, flexible and accessible in the years to come.

Recreate Masterpieces of Modern Art with Javascript

JavaScript is not just for web apps. This talk looks at JavaScript as an artistic and visual programming language and serves as a primer on generative art. The audience will learn how to recreate one of Damien Hirst’s Spot paintings and one of Piet Mondrian’s Composition paintings in the browser. JavaScript is commonly used to manage interactivity, data, and application states. However, we will use masterpieces of modern art to illustrate JavaScript’s potential to manipulate visual space, color and shape.

In the recent past, creating art for the web - usually in the form of Flash or Java applets - was a completely separate workflow from developing business logic for an app. This talk will show that these workflows can be combined. Also, learning the basics of generative art and how to “draw” for the web is creative and fun!

JavaScript Takes on Genetically Evolving Cellular Automata

Genetically evolving cellular automata -- that's a mouthful. Let's break it down

1. We will be looking at cellular automata. A cellular automata is a set of units governed with very simple rules. These units make up a complex system, or model. 

2. We can train cellular automata to genetically evolve, making themselves better overtime. We can make them adhere to a set of rules that would make the system reach a certain outcome at the end of N generations. We can even use these concepts in the wild.

3. We will be doing it all with JavaScript.

A brief history and mishistory of modularity

"MAKE IT MODULAR," they said. "IT WILL BE BETTER," they said. Modularity is a term so common in today's software industry, that it's easy to uncritically accept it as a fundamental software development principle. but what does "modularity" *actually* mean? Where does this idea come from? Where is it going? This talk will walk us through the technical etymology of "modularity", stepping through the intellectual breakthroughs alongside the fast spread misconceptions. We'll conclude by exploring the implications of modularity's ill-examined history on both its current use today, and where it's heading in the future.

Demystifying Frontend Framework Performance

Developers often consider performance an important factor when choosing frameworks, however it is often not so straightforward when trying to measure the performance of a framework. Micro-benchmarks often cover very narrow use cases and most of the time can lead to wrong assumptions. At the same time high level descriptions of a technology can also lead to biased yet unfounded conclusions. In this talk I will walk the audience through the techniques used in major frontend frameworks - namely dirty checking, virtual-dom diffing and dependency-tracking. I will also compare them in different use case scenarios to give users a balanced idea of how each strategy performs under different circumstances.

Magic of Computer Vision Unraveled

Have you ever wondered how computers "see" images? Do you want to work on an Augmented Reality project or build a NodeBot that can recognize your face? When you work with an image as your data input, sooner or later you'll encounter the magic term "Computer Vision".

It can be intimidating to some. At first, that led me to choose a powerful library that works like magic in an unfamiliar language (C++). It felt like library was a black box and I had no control. I started wonder, what is so magical about computer vision? After all it is just code someone wrote. Can we unravel it? and reconstruct in JavaScript??

The answer is YES. In this talk, we'll start by getting image data from canvas object, then transform the data to alter an appearance of the image. You will get first insight into what data looks like to a browser (hint: it's just an array of numbers !). Finally, we'll go through simple image analysis process to build your own AR app in vanilla JavaScript.

JavaScript as Play

Now that you know enough front end technologies to be dangerous, lets use those skills to make a game. We'll take a look at the open source framework Phaser to learn how to create your own browser based game. Together we'll explore topics such as sprite animation, collision detection, and scoring, by the end we'll have a playable platformer you can tinker with.

The Mad Cousin - Multi-threaded JavaScript

We explore the potential of introducing multithreading to a single-threaded world. Nexus.js is a multi-threaded cousin to Node.js. It introduces a paradigm shift into the world of server-side JavaScript as we know it. In addition to supporting ES6 out of the box, the system introduces promises that run on all CPU cores in parallel. Making it a unique environment to explore the potential of a truly concurrent JavaScript.

The journey begins with the lack of an event-loop. Nexus.js instead implements a cooperative thread-pool scheduler, which allows it to handle tasks in parallel.

We will explore the architecture behind this, how it works, and why this project was launched in the first place. We will also explore the challenges and benefits of scaling in a multi-threaded environment and how it differs from scaling with Node.js on modern hardware.

Nicole Rauch

Software Developer

Nicole is an independent software developer and development coach with a solid background in compiler construction and formal methods.

Event Sourcing a Node.js Application

When it comes to storing application data, a more or less object-relational approach is currently the norm. That means, the current state of the application is stored in the database, and whenever that state changes, the database contents gets overwritten and replaced by the new state. This does not allow us to reason about information we had in the past, e.g. "When did this user change her address?" or "Where did this user live previously?". In other words, we drop data - data that might be important for us in the future. Event sourcing circumvents this amnesia by capturing each and every event that happened throughout the life of the application, and by deriving the current state from the total volume of these events. In this talk, I will show how event sourcing works in general and which peculiarities we need to cater for when applying it to a typical node.js application.

Resilience: Tried and tested approaches to building robust, flexible, and resilient web experiences.

I want to strike a note of caution with JavaScript developers by encouraging them to think in terms of progressive enhancement ...even if that means foregoing the latest and greatest frameworks that rely on client-side JavaScript to render text on a screen.

Pragmatic performance patterns

I'll talk about performance from a pragmatic point of view - give example of patterns I've adapted to make sure I write performant code - without sacrificing readability or code quality. I'll also touch upon how benchmarking can be a part of your workflow from day one and I'll let you all know why premature optimization isn't the root of all evil (and what actually is).
