AWS Lambda@Edge 서비스를 이용하면, AWS의 콘텐트 배포 네트워크(CDN)의 엣지네트워크에서 별도의 자바스크립트 코드를 통해 원하는 애플리케이션 기능을 수행할 수 있습니다. 본 세션에서는 AWS의 콘텐츠 배포 네트워크 활용 방법과 아울러 활용 방법 및 간단한 데모를 통해 엣지 컴퓨팅 서비스를 만들 수 있는 방법을 소개합니다.
ElasticES-Hadoop: Bridging the world of Hadoop and ElasticsearchMapR Technologies
In this talk, we will provide an overview of Elasticsearch for Apache Hadoop (ES-Hadoop), which includes integrations between the various Hadoop libraries, whether batch (Map/Reduce, Pig, Hive) or stream oriented (such as Apache Spark). We will also cover the YARN support and the HDFS snapshot/restore plugin available as part of ES-Hadoop. We will talk about the upcoming ES-Hadoop 2.1 GA release and near-term roadmap.
A status update on JRuby, covering compatibility, Rails, and next-gen performance numbers. JRuby is currently the fastest way to run Rails apps, and we're doing work to make it even faster in the future.
If you don’t test it, how do you know it works? Over the past few years, we have been compelled to write unit and integration tests for our applications--code that validates code--and it is these tests that change a one-off tool into a well-architected, robust, business-ready application. Yet, every new framework requires a new testing framework, so in this session, we will discuss testing frameworks for node.js. You will walk away with a solid understanding of how to write tests against your node.js applications and modules, leading to confidence that your work is business-ready.

Android & Kotlin - The code awakens #03Omar Miatello
A series of 3 events for building apps with Kotlin on Android.
Introduction to Kotlin, a modern language, developed by JetBrains (those who developed the IDE on which is based Android Studio) that compared to Java is more concise, versatile and with better error handling. The code is 100% interoperable with Java, and can be used to write native Android apps or small component.
Powerful JavaScript Tips and Best PracticesDragos Ionita

Actors testing is different from what you are used to. First, you have messages instead of calls, second, you have to deal with concurrency and all the consequences that it brings with it:
* Thread.sleeps in tests;
* Flakiness;
* Green on laptop / red on jenkins;
* Missed test cases.
Fortunately Akka provides a TestKit which helps to avoid all these things when used properly. Let's take out and inspect tools from this kit and learn couple of useful patterns.
API first with Swagger and Scala by Slava SchmidtJavaDayUA
How does one scale the development of a service landscape in a corporate enterprise environment utilizing Typesafe's Play and Akka software stack? How does one achieve API uniformity and coherence accross dozens of development teams, getting them and their subsequently developed subsystems to play together nicely? At Zalando we believe firmly in an API first approach, founded an API guild that ratifies and supports the development of APIs, and define them in a formal manner employing the Swagger API representation language.
This was a talk given at HTML5DevConf SF in 2015.
Ever wanted to write your own Browserify or Babel? Maybe have an idea for something new? This talk will get you started understanding how to use a JavaScript AST to transform and generate new code.
Lets look at writing a new Struts 2 application from square one, using the Yahoo User Interface (YUI) Library on the front end, and Struts 2 on the backend. YUI provides the glitz and the glamour, and Struts 2 provides the dreary business logic, input validation, and text formatting.
Ajax is the web's hottest user interface. Struts is Java's most popular web framework. What happens when we put Ajax on Struts?
In this session, we look at writing a new Struts 2 application from square one, using the Yahoo User Interface (YUI) Library on the front end, and Struts 2 on the backend. YUI provides the glitz and the glamour, and Struts 2 provides the dreary business logic, input validation, and text formatting.
During the session, we will cover
* How to integrate an Ajax UI with Struts 2
* Basics of the Yahoo User Interface (YUI) Library
* Business services Struts can provide to an Ajax UI
Who should attend: Ajax developers who would like to utilize Struts as a back-end, and Struts developers who would like to utilize Ajax as a front-end.
To get the most from this session, some familiarity with an Ajax library, like YUI or Dojo, is helpful.

Accelerate your Kubernetes clusters with Varnish CachingThijs Feryn
A presentation about the usage and availability of Varnish on Kubernetes. This talk explores the capabilities of Varnish caching and shows how to use the Varnish Helm chart to deploy it to Kubernetes.
This presentation was delivered at K8SUG Singapore. See https://feryn.eu/presentations/accelerate-your-kubernetes-clusters-with-varnish-caching-k8sug-singapore-28-2024 for more details.
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.

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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
