Promises are a popular pattern for asynchronous operations in JavaScript, existing in some form in every client-side framework in widespread use today. We'll give a conceptual and practical intro to promises in general, before moving on to talking about how they fit into Angular. If you've ever wondered what exactly $q was about, this is the place to learn!
Asynchronous PHP and Real-time MessagingSteve Rhoades
With every major browser supporting WebSockets, HTML 5 has changed how we handle client to server communications. The high demand for real time client and server messaging has developers flocking away from PHP to languages such as Node.js. In this session we'll explore the libraries and extensions that make Asynchronous PHP possible and analyze the performance differences with Node.js. In addition we'll identify use cases and walk through examples of how Asynchronous PHP can handle everything from WebSockets and Message Queues to MySQL.

It is believed that the front end is only one part of the job. We need a backend to store data, we need some DevOps. Oh, I also forgot about QA. There are legends about titans from the past who could single-handedly draw a design and launch a website.
But here's the real story: we has the Great Idea, it won't work without a back-end, there are only front-end developers in the team, outsourcing is possible only in design, the deadline is too near. Just smile and wave... Or we will can realised the project uses front-end technologies only, cut comlicated things, dive into devops. Spoiler: we did it, the Bobuk-Bacek formula works, JavaScript is power.
You will find out how I Love Front-end was launched, what was cut off by Occam's razor and why everyone hates the Mona Lisa.
Audience and level.
Full-stack developers and front-end developers who want to learn how to make back-end for front-end. Just curious guys. Level from junior to middle.

Slowly but surely, promises have spread throughout the JavaScript ecosystem, standardized by ES 2015 and embraced by the web platform. But the world of asynchronous programming contains more patterns than the simple single-valued async function call that promises represent. What about things like streams, observables, async iterators—or even just cancelable promises? How do they fit, both in the conceptual landscape and in your day-to-day programming?
For the last year, I've been working to bring an implementation of I/O streams to the browser. Meanwhile, designs for a cancelable promise type (sometimes called "tasks") are starting to form, driven by the needs of web platform APIs. And TC39 has several proposals floating around for more general asynchronous iteration. We'll learn about these efforts and more, as I guide you through the frontiers of popular libraries, language design, and web standards.
Although Web and mobile apps are getting more capable every day, often your application makes the most sense on the desktop. In this talk, we’ll look at some recent technologies that have allowed significant desktop apps — like Barnes & Noble’s NOOK Study e-textbook reader, or Adobe’s Brackets IDE — to be written in HTML5 and JavaScript. Projects like the Chromium Embedded Framework, node-webkit, and AppJS provide an excellent native-to-JS bridge. With them in hand, you can bring the full power of the Node.js and front-end ecosystems to bear, while still gaining the advantages of running as a native app.
From ReactPHP to Facebook Hack's Async implementation and many more, asynchronous programming has been a 'hot' topic lately. But how well does async programming support work in PHP and what can you actually use it for in your projects ? Let's look at some real-world use cases and how they leverage the power of async to do things you didn't know PHP could do.
"As an asynchronous event driven JavaScript runtime, Node is designed to build scalable network applications" così si presenta Node.js, piattaforma tecnologica che - grazie alla sua immediatezza e produttività - ha conquistato dapprima startup e piccole aziende, fino a ritagliarsi uno spazio importante in realtà come IBM, LinkedIn, Netflix e Yahoo. La stessa Microsoft ha riconosciuto le potenzialità della piattaforma, tanto da integrare Node.js in Visual Studio Code e nelle ultime release di Visual Studio, oltre a basarci alcuni dei propri servizi di Azure come "Mobile Services" e "Functions".
In questa sessione vedremo come implementare con Node.js alcuni scenari applicativi comuni nell’ambito dello sviluppo web, analizzando quando la sua adozione può portarci vantaggi nel nostro lavoro quotidiano. In conclusione, faremo una breve panoramica architetturale, descrivendo alcuni scenari di cooperazione tra .NET e Node.js nello stesso sistema.

It's silly to write the same functionality over and over again. Auth is the most often implemented functionality at web projects. Let's check how can we speed up development by using one of auth provider: Amazon Cognito, Google Firebase or Auth0. On code level we will use custom React Hooks.
Event looped, asynchronous programming is possible with PHP! Streams, promises, async IO, web sockets -- you can do it all, with React PHP. Presented by Luke Kysow.

The time of static or dynamically generated sites is long gone. Non-stop interaction with users is the new normal. However, polling with Ajax requests is processor intensive and cumbersome. Websockets allow you to interact with users in real-time without increasing system load. We'll go through the basics and see all the different options, illustrated with live examples of how and when to use it, as well as when not to use it.
Async/await is a new language feature that will ship with Swift 5.5 this year. There’s no doubt it will have a significant impact on how we write asynchronous code.
In this talk, we’re going to look at some use cases for async/await, how we can call existing Swift APIs using this new feature, and why your decision to write your SDK in Objective-C might turn out to have been a very clever move.
We’ll also have a look at the refactoring support Apple is adding to Xcode and how it will help you migrate your existing code base.
[WSO2 Integration Summit Madrid 2019] Integration + BallerinaWSO2

Ballerina is a new programming language designed around this problem. This deck introduces the challenges and background of why Ballerina has been created, as well as demonstrate the core features of the language.
Managing State in React Apps with RxJS by James Wright at FrontCon 2019DevClub_lv
Redux is one of the most popular technologies for the management of shared state across entire React applications, which can be complemented by Redux Observable to describe asynchronous side effects with RxJS. This approach, however, adds cognitive load when balancing the varying concepts across these three libraries. What if we could use RxJS exclusively for managing state in our React apps? This talk will demonstrate this possibility and the benefits it provides.
Serverless computing is becoming increasingly popular in cloud native development. It provides advantages to an organization in terms of cost, scalability, and agility. Ballerina was created to make integrations simple. It also adds agility to the development process. What will happen when Ballerina meets serverless? A couple of serverless platforms have already started supporting Ballerina as a runtime.
This presentation will discuss the advantages of adopting a serverless strategy, the work done in running Ballerina in OpenWhisk and Kubeless, and other efforts going on to support Ballerina in the serverless world.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
