Meet our speaker lineup

  • I studied business engineering; after finishing college I started working as a financial analyst for 3 years. In my first year working as a financial analyst I started having some interest in coding, so was there when I decided to spend all my free nights and weekends to study by myself until I decided to quit my, so I can code more and make it my first job. This is my first year as a full-time developer, in this year I had contributed to Node.js, Next.js, and Express.js. Also, I had created multiple npm packages including easygraphql-mock, validate data schema on express.js, mongodb plugin that encrypts the data just before saving it to the database and more.

    Juan Guillermo Murillo Castillo

  • Well, I think the most important thing I can say about myself is that I love learning and I really love creating things. And, as I can't stay away from writing the best code I'm able to, you can find me almost every day on [GitHub](https://github.com/lucasfcosta), contributing to open-source projects and also helping to translate and produce content for other developers. I have already spoken at countless meetups and major events in Brazil such as Front In Poa, JSDay Recife, and The Developer's Conference Florianópolis and at international events such as Voxxed Days Bristol, O'Reilly's 2017 FluentConf and NebraskaJS 2017. Now that I've moved to the United Kingdom I expect to do even more talks all around the world :) I've been one of [Chai.js](https://github.com/chaijs/chai) core maintainers since 2015. Chai is one of the most downloaded NodeJS modules and the most famous assertion-focused library around, with outstanding [4.2 million monthly downloads and lots of dependents](http://npm-stat.com/charts.html?package=chai). Being part of such a huge project has not only helped me to learn how to manage an Open Source community but also made me understand difficulties other people had when trying to test their software and then think of ways I could help them to solve their problem. I am also a core maintainer of [Sinon.js](https://www.npmjs.com/package/sinon), which is another very popular project among JavaScript developers and uses lots of meta-programming magic to accomplish its tasks. Now, as a Software Engineer, I still find my experience very useful to write code that has fewer bugs in less time, and I hope I can teach you a trick or two which may save the whole world (or just your job) one day!

Alexandra Cárdenas and Olivia Jack

Live coding performance by Alexandra Cárdenas and Olivia Jack, using JavaScript to generate electronic music and visuals in real time. The code is written and modified throughout the performance, and projected so that the audience can see the algorithms as they unfold. The practice of sharing code with the viewers treats code not only as a tool for creating applications, but as a live, creative material that can be heard and experienced.

10KB or Bust: The Delicate Power of Webpack and Babel

Brian Holt

Your app is bigger and slower than it needs to be.

Without rewriting app code we can squeeze more performance out of your code by tweaking Webpack and Babel. These tools are immensely powerful but it’s a delicate dance to get them to play nice. This talk is full of tips and tricks to get you there.

After three years of tooling around with Webpack and Babel at Netflix, LinkedIn, and Reddit I’ve gotten some battle-won knowledge that I’d like to share with you all. Some non-intuitive tricks that lead to smaller bundles, faster parse times, browser-engine opts and de-opts, and faster-perceived load times. While these examples will use Preact to make examples this applies to any application that uses these two phenomenal tools. You’ll be surprised at what you can do just turning a few knobs.

Shipyard: summarize, navigate and explore multidimensional data without coding

Juan Guillermo Murillo Castillo

First, I will make a brief introduction to visualization and the most important things about it. Later, I will explain which is one of the most important problems in visualizing multi-dimensional datasets. Finally, I will show Shipyard, a visualization tool that I developed with my thesis advisor to ease the navigation, exploration and summarization of large multidimensional datasets. This web application allows the user to load a dataset, preprocess, navigate, explore, summarize, filter, visualize and export the filtered data or the visualization generated.

Creating Your Own Image Format in the Browser

Trent Willis

JavaScript and the web platform have evolved a lot in the past couple of years. In particular, Service Workers have given modern web applications tremendous power. They allow our apps to deliver content offline, send push notifications, and...create their own image formats? It’s a bit outlandish, but yes!

In this talk, we’ll go on a journey that starts with a dream and a Service Worker and ends with us having created our very own image format that works in the browser. Along the way, we’ll learn about some fantastic new web technologies, such as Streams and Web Assembly, that are shipping in browsers today.

El error en dar un error por hecho

Gabrielle von Koss

Ésta plática es motivada por las palabras que elegimos. El objetivo es observar una comparación entre el lenguaje usado para escribir mensajes de error y el que usamos para comunicarnos en persona, destacando así el espacio que existe para mejorar estos conceptos dentro de la comunidad tecnológica.

El poder de las palabras que usamos puede fácilmente pasar desapercibido en nuestro día a día. Sin embargo, no sirve suponer que existe cierto conocimiento, usar acrónimos o que seamos vagos, ya que la persona que usa nuestro código existe dentro de un espectro infinito de experiencias y comprensión. Similarmente, hay falacia en dar por hecho que la persona con quien nos comunicamos entiende todo nuestro modo de pensar, y que sea familiar con las referencias que damos al hablar — es muy fácil olvidarnos que otros no saben lo que nosotros sabemos.

Por medio de esta plática, vamos a examinar algunas maneras por las cuales nos comunicamos, entender cómo esto puede afectar nuestro público y cómo nos podemos hacer más conscientes de nuestros estilos comunicativos.

Linear Algebra for FE Developers

Elizabeth Ramírez

In Linear Algebra, not only the data that comes from the discretization of continuous systems can be represented in matrix (or tensor) structures, but also the operations performed on this data. Such operations can be linearly composed to produce more complex results and find better representations of this datasets.
For example, in Computer Graphics, imagery or imagery time series are represented with sets of values arranged in n-dimensional matrices, being suitable to be manipulated with functions of matrices.
This presentation will be focused in matrix functions and their numerical implementation for datasets represented in matrix form, as well as the computation cost of these operations, covering (but not limited to) the following topics:

- Coordinate Systems
- Transformations: Rotation, Projection, Stretching, Squeezing, Sheering, Reflection
- Polynomial Interpolation

Finding and debugging memory leaks in Node.js

Giovanny Gongora

Performance metrics? Response time higher? Memory leak? We would walk through different memory leak situations to identify and analyze patterns that produce an increase of memory, CPU usage, and the load average over time, without any apparent reason. We'll start talking about taking the time to set up a proper test environment to repeat the exact same conditions as in production. Then we'll discuss how to access Node.js memory using V8 Inspector & Chrome Dev Tools, create a dump of the heap memory for the inspected application, with a lot of details about the memory usage, watching memory allocation in real time and finally a compilation of best practices about how we could end fixing the memory leak. In the end, we'll be able to use the right tools to monitor, understand, and debug the memory consumption of a Node.js application on time.

Migrating Pinterest profiles to React

Imad Elyafi

We all have been in situation when we were in one platform and had to move to another. While it’s relatively easy to build a new web app in React, migrating a service that’s constantly changing and used by millions of people is a much more complicated challenge. It’s like changing the engines of an airplane while mid-flight.
Some of the problems are: rendering Javascript on the server, measuring the impact, debugging issues, dealing with old resource library and rendering React components inside of the existing JS Framework.
The talk is about techniques we tried and challenges we faced while migrating to React at Pinterest. Also, we’ll share our performance and engagement gains after migrating Pinterest’s profiles to React.

Una historia de amor entre JavaScript y C++

Fredy Andrade

El desarrollo de experiencias interactivas con buen performance es importante! JavaScript es un lenguaje fácil en algunas casos y un mal uso del mismo, puede llevarnos a construir experiencias interactivas lentas y no muy amigables con el usuario.

En esta charla exploraremos la delegación de responsabilidades en las que JavaScript -o Node.js- puede ser fuerte y otras en las que C++ puede tener un mayor performance en la Generación de Niveles Procedimental para videojuegos.

Ven y conoce esta historia de amor 😊

Teaching Programming to Kids - by a 13 year old

Jason Straughan

Teaching programming to children is hard. Computer Science topics can be difficult to grasp using standard programming languages and tools. Using MIT’s Scratch programming platform, creating games and working software is simple and fun thanks to their drag and drop interface.

Creating loops, controls structures, variables, and other common programming tasks allow users of all ages to build fully functioning games and applications. In this session, we will be creating an entire game from scratch in Scratch.

To prove that this is as simple as it sounds, this session will be led by a 13-year-old. What better way to learn how to teach kids how to code than by learning from a kid?

If you have a kid, are related to a kid, know a kid, or think you may know a kid in the future, then this session is for you.

This will be a dual speaker session lead by Michael and assisted by his father, Jason. There will be live coding, good content, and bad jokes.

The Lost Art of MIDI – Bringing < bgsound> Back to the Web

Feross Aboukhadijeh

In the days of Geocities and Angelfire, a quirky HTML tag called < bgsound> enabled sound files to play in the background of webpages. Usually, these files were in the MIDI format. What a glorious era that was! Sadly, < bgsound> has been removed from browsers and MIDI is obscure and hard to play back. In this talk, we'll bring MIDI and < bgsound> back from the dead using WebAssembly, Emscripten, Web Audio, and Web Components. When we're finished, you'll be able to give your webpages the 90's treatment in a modern, standards-compliant way!

Muses Code JS or How Communities Change People

Tanya Butenko

When I decided to change my career one of the important factors was JavaScript community - a welcoming place with people who had similar interests. For me, it was surprising that everyone was so eager to share knowledge for free, unlike many other professions. Then I decided to be involved. After 2 years I started Muses Code JS (former NodeGirls) and it changed my life and lives of other people. Now I want to share lessons I've learned, how leading countrywide community changed my perception of some things and how we managed to change the lives of some women and opinion of some men.

More details:

How communities change lives:
- what I've learnt by running and organising different types of very successful events, why it is important
- why it is important to give back to the community and why even bother
- how to build inclusive and diverse community
- success stories with lessons learned

In few words, Muses Code JS (former NodeGirls) is a non-profit organisation that supports women and other gender minorities in IT and helps to show opportunities in IT and teaches on how to code. We run free workshops, events and internship programs around Australia and outside of it. We have few thousands of followers and grow.
It is not the only community I support, it is many others and all of them teach you something new. My motto that I always share with others - if you want to learn more about the topic - organize the event!

My talk is highly inspirational with examples of real people's lives change. Did it on NodeSummit 2018 and got lots of positive feedback. If you have any questions, please, contact me for any additional information.

There is a Bluebird in my talk that wants to get out

Lucas da Costa

This is not your usual functional programming talk. In it, I'll explain lambda calculus itself and show how exciting it can be to derive combinators from the most elegant ideas in computability theory.

In it, we'll explore functional programming from a different angle. Instead of talking about functors, bifunctors, profunctors, monads, comonads and other popular concepts we'll take a step back and learn Lambda calculus itself.

How does lambda calculus express computation? How can we represent concepts such as `true` or `false` or, even better, how can we express boolean logic? How can we do arithmetic operations without using any numbers? What about loops? These are a few of the questions we're going to answer and we're gonna do that with small incremental steps.

During all this process we'll also identify some unique and exquisite creatures: birds (or combinators, as some other people call them). These are patterns that will emerge naturally from the process of rediscovering lambda calculus and are guaranteed to blow everyone's mind by their simplicity and elegance.

Rediscovering lambda calculus feels like rediscovering math and finally understanding what is behind functional programming.

We'll finally let our Bluebird out. We won't be too tough for him.

Preprocessors, Components, and CSS in JS or: How I Learned to Stop Worrying and Love the Website

Jackie Balzer

Behance’s codebase has existed in various states for 8 continuous years - which includes multiple major redesigns, brand overhauls, backend framework changes, JavaScript frameworks, CSS preprocessors, templating languages, feature births and deaths, product integrations, and more.

And now, we are working on our latest project: moving our JavaScript and Sass to Vue.js and CSS Modules.

This talk explores our journey over the years, from how we choose which technologies to implement, how we piecemeal large rewrites while maintaining developer sanity and website integrity (and how to cut corners gracefully), how we manage technical debt, and perhaps most importantly: how to be at peace with the reality of a fragmented codebase.

De 2D a 3D: cómo diseñar interfaces de usuario en Realidad Virtual

Fabio Cortés

El auge de la realidad virtual ha modificado la forma en que diseñamos y desarrollamos experiencias de usuario. Similar al descubrimiento de las técnicas de la perspectiva en la pintura, propias del Renacimiento, las interfaces de usuario se han volcado al desarrollo de ambientes en tres dimensiones; antes que propiciar interfaces planas, en las que las animaciones eran el principal móvil de la interacción con el usuario. Lo anterior, se ha convertido en un reto para todos los programadores y diseñadores, dado que las múltiples posibilidades que dicho cambio trajo consigo aún no han sido del todo exploradas: sonidos holofónicos, pistas ambientales, ciclos día/noche, simulaciones climáticas e interfaces digitales antropomorfas, son tan sólo algunas de las posibilidades que la perspectiva en tres dimensiones han surgido en el diseño de interfaces.

En esta charla, exploraremos algunas de estas posibilidades; en especial, tres de los patrones de diseño más comunes: 1) inputs e interacciones; 2) espacio y escala; 3) diseño de ambientes en tres dimensiones. La explicación de dichos patrones se dará en el marco de su aplicación en los dos ''frameworks'' más populares para desarrollar realidad virtual, que son A-Frame y React 360.

Tracing Node. The Open Source Edition

Daniel Khan

Node alone doesn’t guarantee flawless code execution with stellar performance and finding problems in distributed systems is hard.

Tracing gives you both visibility into distributed code execution and the data you need to optimize performance and remove flaws in your code.

Join my talk where I cover

- the key performance metrics and how to collect them from Node.js
- challenges of asynchronous tracing and content propagation
- the different Open Source approaches and their use cases
- an end-to-end live sample that shows you how to get started with tracing your apps today

Automated Testing for the Modern Web

Jennifer Shehane

End-to-end tests are a crucial part of the testing pyramid, yet they are often overlooked entirely. They are notorious for being hard to set up, flaky when they run, and slow to debug.

Why is running end-to-end tests so unreliable? Is there a way to write useful end-to-end tests quickly without the hair-pulling frustration?

In this talk we’ll look at the architecture behind automated testing tools built on top of WebDriver. We’ll explore the communication flow between WebDriver and the browser to uncover why end-to-end testing for the web has been so temperamental.

Then we’ll delve into Cypress.io - a new, refreshing approach to testing web applications. We’ll examine Cypress’ anatomy and show how its non-reliance on WebDriver makes it a better fit for testing the modern web. Using this new tool, your tests can react to your application’s events in real time, read or alter web traffic on the fly, and programmatically interact and control your application while testing. You’ll walk away with the means to have your tests reliably run and quickly execute, giving you the ability to test your applications while you develop for the first time.

How I ended up automating my curtains and shouting at my laptop

Luke Bonaccorsi

A few years ago I set about building a simple JavaScript chatbot that then quickly grew into a chat based automation system that I use every day. The experience was, and still is, a fantastic learning opportunity and in this talk I’ll share my progress, my reasons for doing it and what I’d like to do in the future whilst also hoping to inspire you to build something weird.

"To see what others can not... You must climb the mountain" - A Introduction to Load Testing

Nathan White

Load Testing can be fun and exciting when done with the right tools. In this talk we will explore the various aspect of load testing (load, endurance, stress and peak) to increase stability and scalability of our applications, ultimately making us better developers. Specifically, we will be looking at `k6.io` to automate and write tests in ES6 javascript! Bonus content! Looking into dynamic test generation via JavaScript.

5:20 pm

Speed, Speed, Speed: JavaScript vs C++ vs WebAssembly

Franziska Hinkelmann

In Node.js, we can use WebAssembly modules and native C++ addons. If your app has performance critical parts, should you stay in JavaScript? Or write a native C++ addon? Or use WebAssembly? We’ll look at how these options compare performance wise and which one is best for different workloads. So the next time you need to optimize for speed, you know your options.
