    What's It Like Being a Open Source Maintainer Anyway?

    Tags: Open Source, People, Social

    Open Source seems to be the way of the future for most software development, but what does the actual day to day look like for those people who are helping to shepherd projects both big and small. And why would you get involved?

    In this talk, I will walk through my experiences - the ups and the downs - of being involved with a number of open source projects over the previous few years, as a maintainer, advisor and keen observer.

    I will share things I've seen succeed on projects, things that cause projects to fail, and share some thoughts on what the future hold for creating sustainable open source projects might look like.

    Server side rendering in React

    Tags: Back end, ReactJS, Progressive Enhancement

    It can be really difficult to make sure your web app works on every device and every browser. One simple way to ensure great cross platform support is to make your site work even when JavaScript is not enabled.

    In this talk I will cover some of the tips and tricks to successfully render a React application on the server side. I’ll also talk about when you should and when you shouldn’t render on the server.

    Scaling applications using Angular and TypeScript

    Tags: Front end, Angular, Typescript

    The future of web development is components based. Building your application in a modular way using decoupled components gives you the power to reuse code and increase testability - add types and cool things will happen.

    This talk is going to walk you through features in Angular 2 and explain the benefits of using TypeScript when implementing your applications.

    SIM based connectivity solution for IoT

    Tags: Webservices, Messaging, IoT

    Mobile connectivity is becoming more and more a key success factor for many IoT projects.
    But if mobile connectivity is bound to a single network you simply won’t always have the quality of network coverage that you need.
    Therefore, whatever mobile offers the "wherever SIM". The IoT/M2M SIM card dynamically switches to the strongest network – integrating 400+ radio networks in 160+ countries all around the world.

    SIM cards and endpoints can be easily managed in real-time via the intuitive user-interface web-service or directly from the customer’s software application via an easy-to-integrate API.
    The set of advanced security and development features for our web-service will be discussed.

    Debug the web everywhere with Vorlon.js

    Tags: Front end, JavaScript, Debugging

    Debugging has always been a challenge when it comes to remote cases.
    For the web there is F12 tools but what about debugging your website on a phone? On a tablet? On a connected car?

    This talk will be about Vorlon.js, a cross-platform, open source tool to remote debug websites and node.js process.

    Real time front-end alchemy, or: capturing, playing, altering and encoding video and audio streams, without servers or plugins!

    Tags: Video, Encoding, Front end

    As new features are added to the Web platform, the kind of experiences we can build become amazingly interactive and immersive--a huge leap forward from the static document based web of yore!

    Nowadays we can access webcams and play 3D audio and graphics, all in real time and in the browser, but there was a missing piece: capturing and encoding! Most solutions involved either sending data to servers or porting C++ encoders to JavaScript, none of which were particularly efficient or desirable for privacy or performance reasons.

    Thankfully there is a better way: the new and shiny MediaCapture API, and in this talk you will learn all about it. Streams will be no strangers to you anymore, and you might even be tempted to cross a few of them---just for fun!

    Need Robust Software? Make It Fragile

    Tags: Testing, TDD

    In any software project, the goal is to create something stable.
    We don't want it to break in front of a user. We also don't want our website to show an "internal application error" instead of a web page.
    We want our software to work, not fail.

    That's a perfectly valid and logical desire, but in order to achieve that, we have to make our software as fragile as possible. This may sound counter-intuitive, but that's the way it is.
    The more fragile your app is in development, the more robust it is in production.

    I will demonstrate, with practical Java examples, what Fail Fast means and how it helps us make software more stable.

    The Story of Appium: Lessons Learned Creating an Open Source Project, 0 to 100,000 Users

    Tags: Mobile, Hybrid, Cordova

    When I demo’ed what is now called Appium at the Selenium Conference in 2012 I had no idea what I was doing starting an open source project. I knew little about how open source operated and worked behind the scenes.
    Thanks to the help of a great community and the advice of some seasoned open source contributors, Appium has quickly become the most popular open source mobile automation framework.
    Along the way, mistakes were made, lessons were learned, and occasionally we got things right.
    I’ve put together a collection of stories and lessons that I’d like to share with others to help everyone manage, contribute to, and consume open source software projects more effectively.

    Grudging monkeys and microservices

    Tags: Microservices, Devops, Architecture

    Microservices are all the rage, as they promise to lower the complexity of your applications by slimming them down to the bare essentials of one single feature.
    But as you enter the microservices world, there's a whole universe of extra details that you need to take into account.

    This is a story of how to approach microservices from an architect perspective, with a bunch of monkeys.

    Ethical Design

    Tags: Design, Accesibility, Ethics

    Ad networks, analytics, social buttons; these are usually third party scripts. Some of us build them, and almost all of us use them on our sites. But what are these scripts doing? How do they affect our sites and the people who use them? What’s happening with the data they collect?

    As developers, we are the gatekeepers for the web. We need to understand the tools we use and their impact on the people who interact with our work.

    Laura will look at what the web has become, and how we can use the Ethical Design Manifesto to make it better.

    Understanding the CSS Modules Methodology

    Tags: Front end, Tooling, SASS

    CSS is well known for being agressively global. This very behaviour makes it difficult to scale. Style isolation and dead code elimination are only two of the many problems encountered when working with CSS on large and long-lasting codebases.

    That’s why a lot of clever people came up with a lot of clever ideas to make it easier to write locally-scoped, easy-to-test, composable and scalable CSS. Among these ideas, one seems to have gained a lot of traction lately: CSS Modules.

    In this talk, we will see what are CSS Modules, what they intend to solve, and how to use them. I think you’ll be surprised how little difference there is between authoring CSS Modules, and preprocessor-powered stylesheets.

The Workshops

Be part ouf our awesome workshops.

  • Skroutz redesign: how to approach Card Design & SASS content-specific breakpoints

    The workshop is a case study about the methodology, the procedure and the technical solutions that we followed in the recent redesign of

    Specifically, we will demonstrate the challenges and needs we tried to solve through the application of Card design, the solutions suggested and finally how we managed to implement these solutions in HTML & CSS, keeping our codebase clean and maintainable.

    This workshop is about front-end developers and designers who are familiar with basic design & Web UX terms, responsive design, and those able to understand SASS usage.

    Hands-on/interactive, but laptop is not required.

  • Building a workable Chrome Extension in React+Redux

    Written in HTML, JavaScript and CSS, Chrome Extensions are made up of various different pieces, namely the background script, the content script, popups and option dropdowns. In this workshop we will demonstrate a lean paradigm based on Redux to facilitate communication between the different building blocks and we will combine React with shadow DOM gimmicks to accomplish better content script encapsulation.

    This is for everyone.

    Laptop is required.

  • GitHub Patchwork (for the more advanced users)

    Patchwork is a self-directed, hands-on workshop for learning Git and GitHub. The atmosphere is casual and informal; it is not an event full of presented tutorials and copious note-taking. You will be able to go at your own pace, with the help of a community mentor nearby in case you run into any trouble.

    This is for anyone that wants to learn how to use or already uses GitHub. Both beginners and intermediate users.

    Hands-on, self-paced, you need a laptop and some preliminary work a day or two before the workshop.
