JavaScript is single threaded, so understanding the async patterns available in the language is critical to creating maintainable NodeJS applications with good performance. In order to master “thinking in async”, we’ll explore the async patterns available in node and JavaScript including standard callbacks, promises, thunks/tasks, the new async/await, the upcoming asynchronous iteration features, streams, CSP and ES Observables.

Explaining ES6: JavaScript History and What is to ComeCory Forsyth
An overview of some of the history of JavaScript, how it became ECMAScript (and what Ecma is), as well as highlights of the new features and syntax in ES6 aka ES2015.
Originally presented to the New York Public Library on June 4 2015.
In this talk I presented three important topics in Kotlin Standard Library: Scope Functions (let, apply, also, run and with); Annotations (Deprecated, Experimental, Jvm*, DslMarker); and Delegates (lazy, vetoable, observable)
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!
A brief look at the new features coming in Javascript ES6:
- Scope and control
- Iterators and Generators
- Collections
- Typed objects
- Direct proxies
- Template strings
- API improvements
- Modularity
Reactive Programming Patterns with RxSwiftFlorent Pillet
In this introduction to reactive programming and RxSwift you'll learn how common problems are solved in a reactive way to improve your architecture and write more reliable code.

Callbacks, Promises, and Coroutines (oh my!): Asynchronous Programming Patter...Domenic Denicola
This talk takes a deep dive into asynchronous programming patterns and practices, with an emphasis on the promise pattern.
We go through the basics of the event loop, highlighting the drawbacks of asynchronous programming in a naive callback style. Fortunately, we can use the magic of promises to escape from callback hell with a powerful and unified interface for async APIs. Finally, we take a quick look at the possibilities for using coroutines both in current and future (ECMAScript Harmony) JavaScript.
The next version of JavaScript, ES6, is starting to arrive. Many of its features are simple enhancements to the language we already have: things like arrow functions, class syntax, and destructuring. But other features will change the way we program JavaScript, fundamentally expanding the capabilities of the language and reshaping our future codebases. In this talk we'll focus on two of these, discovering the the myriad possibilities of generators and the many tricks you can pull of with template strings.

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.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
