Vert.x vs akka

Presented at JAX London 2013 Vert.x is a lightweight, high performance, application platform for the JVM that's designed for modern mobile, web, and enterprise applications. The recent Vert.x 2.0 release marks a coming of age for Vert.x, as it progresses to a fully independent project. We'll dive into the Vert.x 2.0 release and show how the powerful new module system enables a Vert.x ecosystem by allowing modules to be re-used via Maven and Bintray repositories. You'll also learn about how better build tool and IDE integration makes developing applications with Vert.x a breeze.

Vert.x is a new JVM based application framework with an event driven, asynchronous programming model. With APIs available in Java, JavaScript, Ruby, Python and Groovy, developers are given complete freedom to implement their application in the language of their choice. Starting with the core Vert.x concepts, this presentation will walk attendees through the components of a simple vert.x based application. Through this process, attendees will gain an understanding of how Vert.x: - provides for a way to use several different languages in the same application - takes advantage of JVMs excellent multi-core capabilities - uses a module-based framework for packaging and hot-deployment - communicates with other processes via a distributed event bus - exposes an asynchronous programming model with very simple concurrency With this presentation, viewers should gain a deep-enough understanding of Vert.x to be able to evaluate the platform for their own projects.

With the advent of mobile web and IoT (Internet of Things), today's applications need to handle a lot of concurrent requests while staying responsive and easy to scale. Infrastructure plays a role in achieving these goals, but changing your programming style can help too. In this presentation, we will make the case for reactive programming, and introduce RxJava in particular. Then we will guide you through the process of building a real-life web application, based on Vert.x 3 and RxJava, communicating with databases, external services and modern datastores. You will learn how Vert.x integrates with RxJava, and why its simplicity makes it a perfect runtime for reactive applications.

A lot of the cloud discussion centers around which hypervisors are the best, and which management tools will simplify one's life the most. But is it the whole story? While addressing the problems from the lower and higher layers, the middle man -- the guest operating system -- is usually left behind. This talk will introduce OSv — a new from-scratch operating system written by a group of former Linux veterans designed specifically for cloud deployments. We will showcase the operating system architecture and explain the performance and manageability improvements that can be expected

Semelhante a Vert.x introduction

Join the asynchronous web revolution! Because Ajax-based applications are almost becoming the de facto technology for designing web-based applications, it is more and more important that such applications react on the fly, or in real time, to both client and server events. AJAX can be used to allow the browser to request information from the web server, but does not allow a server to push updates to a browser. Comet solves this problem. Comet is a technology that enables web clients and web servers to communicate asynchronously, allowing real-time operations and functions previously unheard of with traditional web applications to approach the capabilities of desktop applications. This session will start to provide an brief introduction to the asynchronous web, AJAX polling, long polling, and Streaming, explaining the Bayeux protocol, Cometd, Grizzly Comet implementation on GlassFish. Different approaches and best practices to develop comet application will also be discussed. You will learn how to develop the chat application, how to implement distance learning slideshow application, how to manage a chat application from the server and how to develop a two-player distributed game application. Attendees will take away the tactics they need in order to add multiuser collaboration, notification and other Comet features to their application, whether they develop with Dojo, jQuery, jMaki, or Prototype and whether they deploy on Jetty, Tomcat, or the GlassFish Application Server.

These slides accompanied a live install of Triton Elastic Container Infrastructure as described in the following blog post: https://www.joyent.com/blog/spin-up-a-docker-dev-test-environment-in-60-minutes-or-less Presentation abstract: Hardware hypervisors were a first generation approach to the challenges of resource and security isolation, but they’re unnecessarily shackling operations and developers with limitations that are no longer relevant to containerized deployments. We need bare metal performance, but how can we get the security isolation and elasticity that we need without VMs? Container -- truly secure, bare metal containers -- offer an alternative that improve performance while reducing costs (and CO2 emissions too!). What are they, how do they work, and how does containerization affect my apps?? These slides were presented at: http://www.meetup.com/austin-devops/events/223284754/ http://www.meetup.com/PhillyDevOps/events/223197735/ http://www.meetup.com/DevOpsandAutomationNJ/events/223432942/

This month we focus in on WebSockets in HTML5 with Brad Drysdale. You're probably aware of the various chat systems around the web (facebook chat for example) but recently there has been more of a desire for other types of interaction using these technologies. Many have requested talks on Node.js, Comet long-polling, or similar technologies. WebSockets are the evolution of these technologies, and a developing standard being progressed by the IETF. The HTML 5 standard specifies new APIs for storage, drawing, drag-and-drop, and other areas that have made web programming painful. Browsers have already begun incorporating parts of HTML 5 (canvas, for example) even though the specification is far from complete. The HTML 5 Communication section includes two additional connectivity features: Server-Sent Events, a standardization of HTTP push, and Web Sockets, a cross-domain safe, full-duplex connection. Server-Sent Events will make real-time updates and notifications easy, and Web Sockets provide the functionality necessary to build chat for the web without the previously required hackery. Come and hear the latest on what this great technology allows! Brad Drysdale is the Technical Director in EMEA for Kaazing. Brad has also worked at Openwave and Netscape Communications in various pre-sales and technical evangelist roles.

Presented on SuperComputing SC17 on Nov 14/2017 by Dmitri Zimine. This talk is a story of bio-tech meeting DevOps to produce genomic computations, economically, and at scale. Genomic computation is growing in demand as it comes to the mainstream practices of bio-technology, agriculture, and personal medicine. It also explodes the demand for compute resources. In fact, with inexpensive next-gen sequencing, some labs sequence over 1,000,000 billion bases per year. Genetic data banks are growing over 10x annually. How to compute the genomic data at massive scale, and do it in a cost-efficient way? In the presentation, we describe and demonstrate a serverless solution built with Docker, Docker Swarm, StackStorm and other tools from the DevOps toolchain on AWS. The solution offers a new take on creating and computing a bio-informatic pipelines that can run at high scale and at optimal cost. http://sc17.supercomputing.org/presentation/?id=exforum106&sess=sess150

REST does not come with an in-built contract compliance mechanism, which in many ways is a great thing. However, while working with microservice-based systems, it often appears that a practical mechanism that would provide help in shaping and describing REST contracts would come in handy. Similarly, creating integration and acceptance tests in such systems presents many challenges. In this talk, I will present Accurest, a Gradle plugin that allows for both: easily shaping REST contracts and verifying if our app adheres to them using automatically generated Spock tests. I will show how, using Accurest, we can quickly generate automatically-tested stubs from simple Groovy DSL scripts. I will talk about the typical usages and script examples, as well as possible problems and ways of handling them.

How many times have you ever heard the term "Full-Stack developer"? In most of the cases it means that you have to be fluent with a backend language, html, javascript, maybe Android or iOS... What if I told you that you can be a Full-Stack developer using only Groovy? In this talk I'll present the technological stack of Polaromatic, the application with I won the Learning Spring Boot contest, and you'll learn that it's possible to write the whole stack with Groovy: Backend, Javascript, HTML, Android, test, build tool,... Isn't that amazing?

Groovy is a dynamic language that provides different types of metaprogramming techniques. In this talk we’ll mainly see runtime metaprogramming. You’ll understand the Groovy Meta-Object-Protocol (MOP), the metaclass, how to intercept method calls, how to deal with method missing and property missing, the use of mixins, traits and categories. All of these topics will be explained with examples in order to understand them. Also, you’ll see a little bit about compile-time metaprogramming with AST Transformations. AST Transformations provide a wonderful way of manipulating code at compile time via modifications of the Abstract Syntax Tree. You’ll see a basic but powerful example of what we can do with AST transformations.

Reuse has been taught in CS classes since the very beginning. But how should you practically do to reuse functionality from one Grails application in other applications? The plugin subsystem in Grails is an awesome machinery that makes it easy to separate functionality into distinct plugins. Plugins that can be used in many applications with similar functionality. Yet have unique features without creating a maintenance hell. In this session you will learn how to think "feature plugins" when you're designing and developing your Grails applications. We will cover topics like inter-plugin communication using application events and how to support different look and feel for each application using "theme plugins". You will also learn how each plugin can be tested and documented separately from the application. After this session "grails create-plugin" will be your best friend.

Nowadays, companies require very short release cycles, especially in lean startup environments. But to release often: deployments should be routine, not terrifying. configuration should require a few clicks, not a thousand-line shell script. problems should be easy to spot, not buried in a log file. You are a developer that need to release every week or every day with a single git commit and zero-downtime? Easily spot release performance or bugs issues? If required, roll back to previous version in few seconds and one click? And you don't want to manage any dedicated repository, monitoring, build, staging, production servers? So this talk is for you! We will explore Lean startup and DevOps concepts and share our experience on how to create a simple and fully automated build pipeline for Grails apps with a live demo, based on SaaS/cloud services: GitHub, Travis CI, NewRelic, AWS (ElasticBeanstalk, CloudFront), etc.

This talk will cover how to get your application running on AWS VPC and related services. We will go over some related services and their current state like RDS, autoscaling, s3, cloudfront, s3fs, ebs, elastic beanstalk, etc and how your Grails application can benefit from using these. The networking can also be confusing with your application so we'll cover the basics here as well. I will share lots of random nuggets of information that I have learned the hard and and recommended practices of configuration of your VPC as well.

Grails is a complete web application framework that runs on the Java JVM. It is a full-stack framework, and handles all layers from the user interface to the persistence layer. Grails is based on known and proven technologies, such as the Spring Framework and Hibernate. It has been around since 2006, and has made considerable progress around the globe in the past few years. This workshop aims to show how to get from 0 to running application with Grails in three hours - so hold on to your hats! We will touch the following points: Grails application structure Domain model and persistence Controllers Services Testing User Interface

Going beyond the basics of how to use Spock this talk will discuss writing expressive, readable & maintainable specifications using the features of Spock and the Groovy language itself. Concrete examples backed up with live coding will cover a range of topics such as how to structure assertions, effective use of the where: block, appropriate use of mocks and stubs, and driving specifications from a database. The focus will always remain on creating tests that are readable, robust and helpful when you need to deal with regressions.

Groovy is a well established player in the JVM since a few years ago. It's increased popularity across the years has spawned several projects that conform the Groovy Ecosystem. You've probably heard of Grails, Gradle, Griffon and Spock. But what about the rest of projects that are just waiting around the corner to be discovered and make your life easier? This talk presents them tools and libraries that use Groovy as the main driving force to get the job done.

Apache Camel is versatile integration library that supports a huge number of components, enterprise integration patterns, and programming languages. In this this talk I first introduce you to Apache Camel and its concepts. Then we move on to see how you can use the Groovy programming language with Camel as a first class Groovy DSL to build integration flows. You will also learn how to build a new Camel and Groovy app from scratch from a live demo. And we also touch how you can use Camel from grails using the grails-camel plugin. I will also show the web console tools that give you insight into your running Apache Camel applications, including visual route diagrams with tracing, debugging, and profiling capabilities. This session will be taught with a 50/50 mix of slides and live demos, and it will conclude with Q&A time.

CRaSH is the open source shell for the JVM. The shell can be accessed by various ways, remotely using network protocols such as SSH, locally by attaching a shell to a running virtual machine or via a web interface. Commands are written Groovy and can be developed live making the extensibility of the shell easy with quick development cycles. Since the version 1.3, the REPL also speaks the Groovy language, allowing Groovy combination of command using pipes. CRaSH comes with commands such as thread management, log management, database access and JMX. The session will begin with an introduction to the shell. The main part of the session will focus on showing CRaSH commands development with few examples, showing how easy and powerful the development is. The audience will learn how to use CRaSH for their own needs: it can be a simple usage or more advanced like developing a command or embedding the shell in their own runtime like a web application or a Grails application.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.
