Performance advocates spend a lot of time telling developers how to build fast and reliable experiences on the web. Every website is built differently, however. Instead of just listing a number of progressive enhancements and techniques, this talk will try to take a different approach. We’ll first explore who needs to consider improving their site in the first place and see if their is a messaging problem between advocates and developers in the community. We’ll then address concerns that can arise when performance is being worked on and discuss some real and practical solutions. https://2019.jsconf.eu/houssein-djirdeh/performance-empathy.html

“Queers hate techies,” the slogan proudly proclaimed in a window in San Francisco. Being a queer techie, I was immediately conflicted. The tech industry provides a safe haven for many queer folks, myself included. It offers stable employement to us more willingly than other industries. These benefits don’t extend to all queer folks though, and these benefits are often revoked as soon as we step out of line. Queer folks are a model minority in an industry who’s products often negatively impact our community. This talk will dive into these complications and how we can improve the tech industry to make it a truly welcoming place for queer folks. https://2019.jsconf.eu/bryan-hughes/the-contentious-relationship-between-the-lgbtq-community-and-tech.html

Many would argue there are only two hard problems in software: naming and cache invalidation. I’d argue there’s a third problem - abstractions. Whether you’re implementing an API for devs outside of your organization or creating a reusable library for devs on your team, creating the right level of abstraction is difficult. You have to balance flexibility with the ease-of-use. The correct choice is often a function of time constraints, compromise, and trial & error. I’ll talk about how to navigate these issues more efficiently. https://2019.jsconf.eu/johnny-austin/finding-your-abstraction-sweet-spot.html

Until 1992, the web was largely textual, reserved almost exclusively to academia, with the charm of searching for library books via card catalogs. The sea change came when a browser allowed for both text and images to now be displayed in the viewport. Despite some vehement opposition, this was described as the “gateway to the riches of the internet”. This was a technological advancement that some had wagered would further fuel more advacement. We now have seen technologies like APIs, PWAs, DevTools and many more. “The Shape Of The Web” is about both accomplishments and challenges that lay in past, present and future of the web - from its technologies employed and its employed technologists. https://2019.jsconf.eu/henri-helvetica/shape-of-the-web.html

There’s a divisive movement around the world which has arguable impacted the software development community. How can we remain open-minded and respectful when talking about different programming paradigms or languages? In this talk, I will be talking about empathy, how we can have divergent views and still have meaningful conversations. https://2019.jsconf.eu/chidinma-kalu/why-cant-we-all-just-get-along.html

Remember loving to read comics on a Sunday afternoon when you were a kid? Maybe you don’t. In the past, traditional print comics have made it impossible for blind and visually-impaired readers to experience their heroes’ adventures first-hand. Today an increasing number of initiatives like comic book stores for the blind aim to overcome this challenge. What if I told you that the web platform empowers us to even create comics for literally everyone? Alongside a demo application, you see how accessibility best practices enable you to craft an immersive webcomic experience that is not only engaging for the sighted but accessible for everyone. https://2019.jsconf.eu/jessica-jordan/crafting-comics-for-literally-everyone.html

Not long ago, it seemed like JavaScript devices were going to free JS developers from the constraints of the browser and let us control every aspect of our lives as easily as we once controlled hover menus. Though nodebots were captivating, many of us were anxious for the JS device revolution to reach a more mundane destination: our phones. And yet today the constraints of the mobile landscape look not much different from several years ago. We have the same two operating systems, the same two app stores, and same option to write a native app or push people to save what is still mostly a bookmark. How did we cover so little distance, given the enthusiasm, resources, and potential that appeared to exist, and more importantly, how close can we come to a JavaScript phone today? https://2019.jsconf.eu/garann-means/what-happened-to-my-javascript-phone.html

Javascript runs on nearly any platform. Most languages can compile to Javascript. It’s well-positioned to become the lingua franca of programmers, with one problem: Like most programming languages, Javascript is based on English. 89% of the world’s population doesn’t speak any English. Many of those people can’t even read the Latin script. If we want Javascript to be a lingua franca, we need to ensure it is accessible to all people, regardless of their native language. Let’s look at the barriers that non-native speakers face when contributing to OSS Javascript projects and what it would take to remove them entirely, so that two developers could collaborate without speaking the same language. We will see what techniques Javascript can borrow from other languages by taking a look at করো (koro), a project which adds Bengali support to the Go compiler. And, we will learn enough about compilers and character encoding to answer the eternal question: “Could we do this in Javascript?” https://2019.jsconf.eu/aditya-mukerjee/translating-code-to-other-human-languages-and-back-again.html

Original title: Block, unblock, block! How ad blockers are being circumvented, and how they are fighting back. As usage of ad blocking software has risen over the years, an entire micro-industry has popped up catering to publishers - promising to get around the ad blocker and show ads to users of ad blocking software. Some of these techniques rely on browser bugs, or limitations of browser extensions and some are just extremely creative ways to get around ad-blockers. This has forced ad blockers to come up with their own ingenious ways to counter and block the circumvented ads. In this talk, we’ll go over some of the techniques used in this cat and mouse game between ad blocking extensions and the people who want to circumvent them. It’s a fascinating peek into a world very few people seem to know. https://2019.jsconf.eu/shwetank-dixit/block-unblock-block-how-ad-blockers-are-being-circumvented-and-how-they-are-fighting-back.html
