Reading other peoples code
Someone else's code. Even worse, thousands of lines, maybe hundreds of files of other peoples code. Is there a way to methodically read and understand other peoples work, build their mental models? In this talk I will go through techniques I have developed throughout 18 years of programming. Hopefully you will walk away with a plan on how to approach a new code base. But even more I hope you walk away with a feeling of curiosity, wanting to get to know your fellow programmers through their code.

There has been many talks about what WebAssembly (WASM) is, its relation to compilers and how bright our collective future is with WASM in our toolbox. However most talks treat WebAssembly as a semi-opaque box, and mostly as something you can compile higher level languages into. This is a pity! WebAssembly is a fun language to learn, and allows one to write code often less than a magnitude slower than C!
In this talk I will show how to write WAT (WebAssembly Text-format), how to reason about algorithms when all you have is one large slab of memory, how to convert high level constructs such as loops into elementary instructions and how to have fun at the same time! We will convert a number of progressively harder algorithms, each revealing a challenging aspect of working with no abstractions.
Even if you will not write WASM at work, learning at the lowest level of computer tears away the enchantment that abstractions cause, and reveals the magical machine that is the computer.

What the v...DOM?
A deep dive into the vDOM and its core mechanisms. How does the different vDOM implementations differ and are they really that different? And what about lit-html or hyperHTML? How does they differ or do they really?
A testing story in 3 acts
Testing is a solved problem they say. You probably saw talks about it: About the good old dogs and the new kid on the block.
But does it apply to your project? How to test if you deliver a third party component used in many workloads with different integration strategies?

For this we’ll use Mozilla’s A-Frame library, which makes it easy and fun to get into WebXR. We will have a look at how to compose scenes with HTML-like syntax from a range of components and how to modify them in the in-browser editor.

In this talk we learn about the basics of real time 3D graphics and what we need in order to produce realistic looking 3D graphics in the browser by building a very simple ray tracing render engine. Seeing how a seemingly complex concept such as ray tracing can be broken down to simpler concepts will inspire web developers to get creative and enhance their web products with 3D and webVR. We will look at practical techniques and performance tips for browser-based 3D and overcome the obstacle on how to get started.

Cracking JWT tokens: a tale of magic, Node.JS and parallel computing
JWT tokens are powerful artifacts that magicians from all over the World are using to secure modern apps and APIs. But as any other magic tool, those powerful tokens need to be used with caution and mastery, otherwise, they might become dangerous exploitable vulnerabilities. In this talk, I will demonstrate how evil magicians can cast a JWT brute force spell to take control of poorly constructed JWT tokens.
Building High Performance React Applications
React is built with performance in mind. But when is React slow? In this talk we’ll discuss common bottlenecks in React and when you might be making your program work harder than it should. We will discuss how Best Buy builds components that stay fast, even during the enormous stress of Black Friday traffic. You will learn practical ways to speed up your real world React applications today.

Using New Web APIs For Your Own Pleasure – How I Wrote New Features For My Vibrator using the Web Bluetooth API and the Web Audio API
When I first heard about the Web Bluetooth API I was so curious, that I could not wait to try it out. So I asked myself: Which Bluetooth device should I buy? Especially if I do not want to through it away after I was finished experimenting with the API. So obviously a Bluetooth enabled vibrator was a perfect fit. And it came with a serious use case, too: The slogan of the vibrator was "Let him control you", which I found very limiting, so I used the Web Bluetooth API to connect it to the browser, and the Web Audio API, to establish my own slogan: "Let a video control you". In my talk you will learn how to use the Web Bluetooth API to connect a Bluetooth enabled device to the browser. Also you will see what is possible with the Web Audio API, especially when it comes to analyzing spoken words.

Micro Frontends - Think Smaller, Avoid the Monolith, Love the Backend
Microservices are the backend answer to handling complexity and work efficiently with multiple teams. Many frontend apps are also reaching the size where development gets harder and changing fundamental things is too risky. The software does not fit in one frontend developers head any more. Micro Frontends is a way of cutting your software into pieces that can live on their own and are each operated by an end-to-end team. It’s not microservices for frontend people. Think of it as full stack microservices that come with database and user interface. This solves many issues. One of them is briding the gap between frontend and backend developers.
Integrating the UI of multiple applications in the browser, so that the user still gets a seamless and coherent experience comes with a few challenges. This talk explains the Micro Frontends idea, when this concept is useful and what problems it tries to solve. It’ll also highlight topics that you should think about when you build applications this way.

Service Worker: taking the best from the past experience for the bright future of PWAs
There is no doubt that 2018 is the year when Progressive Web Apps will get the really broad adoption and recognition by all the involved parties: browser vendors (finally, all the major ones), developers, users. And the speed and smoothness of this process heavily depend on how correctly we, developers, use the power of new APIs. The main one in PWA concept is Service Worker API, which is responsible for all offline magic, network optimizations and push notifications.
In my session based on accumulated experience of developing and maintaining PWAs we - go through the list of advanced tips & tricks, - showcase best practices, - learn how to avoid common pitfalls, - have a look at the latest browser support and known limitations, - share lots of useful insights.
