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.

Daniel started his career in front of his fathers Sinclair ZX Spectrum. Luckily a brand new thing called \"Word Wide Web\" crossed his path some years later and he built an ugly personal website on GeoCities. Nevertheless he became a go-to-person for websites of all kinds, found out that he needs Perl to send a form by email and MySQL to store things. The rest is history. Perl became PHP, PHP became Node.js and trial and error became craftsmanship. Today, Daniel shares his MacBook with his 4 kids and his knowledge working as mentor, lecturer and lead technology strategist at Dynatrace.

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.

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.
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.
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.
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.
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
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.
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.
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.
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.
Ven y conoce esta historia de amor 😊
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.
La sesión hablara sobre la experiencia de Univision en la migración de esta de una aplicación
monolítica a microservicios y react/node.js como principal motor de las nueva webapp y aplicaciones móviles buscando la
convergencia entre estos dos mundos gracias a las ventajas que nos brindan dichas tecnologías.
Se abordaran temas como la arquitectura actual de univision, el monorepo, shared componentes y styled componentes como ayudan estos a construir componentes reusables en el mundo web y mobile.
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!
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.
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.
Conoceremos un poco sobre los retos y técnicas aplicados en la inteligencia artificial para videojuegos, así como exploraremos algunos ejemplos prácticos en JS enfocados en comportamientos cinemáticos y búsqueda de caminos.
In this talk, I will tell you the story of how I created an open source module mocking a GraphQL
Schema to help developers around the globe to create easy tests for their APIs.
It will describe the story of why and how this was created and the technical review of the module internals
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.
Behance’s codebase has existed in various states for 8 continuous years - which includes multiple
feature births and deaths, product integrations, and more.
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.
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
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.

In this session, I will talk about WebGL, p5.js, and how we can draw and make interactive 2D and 3D graphics within web browsers.
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
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.
