With JEP 271, GC logging has been re-implemented to use the Unified JVM Logging Framework introduced with JEP 158. Unified JVM logging introduced a new JVM option -Xlog, and also defined the category tags for all the different components of the JVM. With 'gc' tag specified for the GC logging, -Xlog:gc option along with the other granular tag-sets, levels and decorations can be used to enable the GC logging for different parts of the GC system at various levels of detail. This talk discusses the GC logging JVM options that are going to be removed in Java 9, and covers in detail the parameters that can be used with Xlog:gc option to get the GC logging equivalent to what we could produce with the now removed JVM options. This session will also take a deep dive into looking at the sample GC logs generated with the new logging mechanism, and will throw light on how those logs can be read and interpreted.

There are several formats for garbage collection logs. Depending on the Java vendor (Oracle, IBM, HP, ...), the Java version (5, 6, 7, 8, 9), the GC algorithm (serial, parallel, CMS, G1), and JVM options (-X..), the garbage collection log format varies. Analyzing all these formats is not trivial. In this session, you will learn not only how to analyze several different GC log formats but also how to spot problems in them instantly.

Simon Ritter, Deputy CTO, Azul Systems The significant change in JDK 9 was the Java Platform Module System (also known as Project Jigsaw). With the encapsulation of internal APIs such as sun.misc.Unsafe, migrating applications to JDK 9 (or JDK 10 or JDK 11) will potentially require more work than moving between releases used to. This session looks at the areas of JDK 9, 10, and 11 that may affect application migration. It covers all aspects: Java language syntax, class libraries, and JVM options (a significant number of which have changed in these releases). Starting with JDK 9, features that were previously deprecated are now actually being removed from the JDK. The presentation discusses these changes in terms of backward compatibility.

Apache Spark is one of the most popular big data projects, offering greatly improved performance over traditional MapReduce models. Much of Apache Spark’s power comes from lazy evaluation along with intelligent pipelining, which can make debugging more challenging. Holden Karau and Joey Echeverria explore how to debug Apache Spark applications, the different options for logging in Spark’s variety of supported languages, and some common errors and how to detect them. Spark’s own internal logging can often be quite verbose. Holden and Joey demonstrate how to effectively search logs from Apache Spark to spot common problems and discuss options for logging from within your program itself. Spark’s accumulators have gotten a bad rap because of how they interact in the event of cache misses or partial recomputes, but Holden and Joey look at how to effectively use Spark’s current accumulators for debugging before gazing into the future to see the data property type accumulators that may be coming to Spark in future versions.

Each service is running in its own process and communicate using lightweight mechanisms, such as HTTP API. These services are built around business capabilities or functional decomposition. Microservice also enables true polyglot architecture – both in terms of language and data. It truly allows you to employ the right tool for the right job. Each service is independently deployable and lends very well to fully automated deployment machinery. Can you take an existing Java EE application and decompose it into microservices? What tools are required to enable CI/CD? How does it enable polyglot? What are different design patterns for microservices? What options are available for Service Discovery, distributed logging, load balancing? What tools do you need to manage such services? Is the complexity being pushed around from service implementation to orchestration? This session will explain how to refactor an existing monolith into microservices and the complexities and benefits it introduces.

What are Hooks in Cucumber? || JUnit Cucumber Tutorial - Scenario Hooks Cucumber supports hooks, which are blocks of code that run before or after each scenario. You can define them anywhere in your project or step definition layers, using the methods @Before and @After. Cucumber Hooks allows us to better manage the code workflow and helps us to reduce the code redundancy. We can say that it is an unseen step, which allows us to perform our scenarios or tests. Why Cucumber Hooks? In the world of testing, you must have encountered the situations where you need to perform the prerequisite steps before testing any test scenario. This prerequisite can be anything from: Starting a webdriver Setting up DB connections Setting up test data Setting up browser cookies Navigating to certain page or anything before the test In the same way there are always after steps as well of the tests like: Killing the webdriver Closing DB connections Clearing the test data Clearing browser cookies Logging out from the application Printing reports or logs Taking screenshots on error or anything after the test To handle these kind of situations, cucumber hooks are the best choice to use. Unlike TestNG Annotaions, cucumber supports only two hooks (Before & After) which works at the start and the end of the test scenario. As the name suggests, @before hook gets executed well before any other test scenario, and @after hook gets executed after executing the scenario. ================================================ Full Cucumber BDD Framework Series Playlist: https://www.youtube.com/watch?v=vHzMJuc9Zuk&list=PLFGoYjJG_fqoBFPevCDZDCufDX5h-o3yO ================================================ Cucumber BDD Framework Code Base GIT URL: https://github.com/naveenanimation20/CucumberSeleniumFramework Note: Please update the latest Cucumber Dependencies before using Examples feature: https://github.com/naveenanimation20/CucumberSeleniumFramework/blob/master/pom.xml ==================================================== ***Subscribe to this channel, and press bell icon to get some interesting videos on Selenium and Automation: https://www.youtube.com/c/Naveen%20AutomationLabs?sub_confirmation=1 ***Follow me on my Facebook Page: https://www.facebook.com/groups/naveenqtpexpert/ Let's join our Automation community for some amazing knowledge sharing and group discussion: https://t.me/joinchat/COJqZQ4enmEt4JACKLNLUg -~-~~-~~~-~~-~- Follow my Site/Blog: http://www.naveenautomationlabs.com ======================================================== Please watch: "Selenium & Automation Interview Preparation - By Naveen AutomationLabs" https://www.youtube.com/watch?v=Og-9P5RwCMM -~-~~-~~~-~~-~-

Speakers: As a major revision of the core Spring Framework, 5.0 comes with a Java 8+ baseline and many infrastructure refinements: e.g. our own Commons Logging bridge autodetecting Log4j 2, SLF4J, JUL by default; streamlined use of Servlet 3.1+; and support for JUnit 5.0! Rest assured that the reactive focus does not impact the existing Spring MVC model; these options live alongside each other. Work continues on the traditional servlet-based Spring MVC stack; there are many further refinements across the framework. Join Juergen Hoeller, Rossen Stoyanchev, Stephane Maldini and the Spring Team to learn about: * Reactive programming: Spring WebFlux framework built on Reactor 3.1, with support for RxJava 2.1 and running on Tomcat, Jetty, Netty or Undertow. * Functional style with Java 8 & Kotlin: several API refinements and Kotlin extensions across the framework, in particular for bean registration and functional web endpoints. * Integration with Java EE 8 APIs: support for Servlet 4.0, Bean Validation 2.0, JPA 2.2, as well as the JSON Binding API (as an alternative to Jackson/Gson in Spring MVC). * JDK 9 support: fully aligned with JDK 9 at runtime, on the classpath as well as the module path (on the latter: as filename-based “automatic modules” for the time being). Attendees will also learn about the role of Project Reactor and its Reactive Streams foundation as the core reactive engine not only for Spring Framework, but increasingly across the Spring ecosystem. Spring Framework 5.0 adopters will benefit from an in-depth understanding of Project Reactor as they start using the 5.0 release.

During Java development, it’s common to restart your application with (almost) every class change you make. For some applications it is not a problem at all, for others - it can be disastrous. In this session, we will look at the options available to us to reload Java classes, from HotSwap to Java agents. There are plenty of tools that you can use to achieve class reloading. You might choose to rely on the standard JVM HotSwap, redesign your application to rely on dynamic class loaders, or integrate a reloading agent into your Java runtime. Every option has its own benefits and drawbacks, so join me for a deep dive on all your choices. Finally, we will cover some of the conceptual challenges in reloading Java classes like state, static initialisers, super class changes and much more. Attend this session to gain a better understanding of class reloading technologies and to become a more productive Java developer.

These days time to value is critical. We all need to develop better software and to get it to customers faster. The quicker the software gets to customers, the more iterations and feedback then the more value we create. Continuous Delivery of Containerized Microservices is the best approach today for developing better software and iterating fast. However without a Microservices Platform it can be challenging creating, building, deploying and managing many independent microservices. In this talk we'll introduce the Fabric8 Microservices Platform which is open source, Apache Licensed and built on top of the shoulders of giants; Docker, Kubernetes and Jenkins. We'll demonstrate how to create microservices easily, have them automatically built, tested and staged with Continuous Delivery and deal with the issues of building microservices architectures like service discovery, high availability, auto scaling, rolling upgrades, circuit breakers, tracing, logging and metrics. After this talk you should be ready to embark on your microservices journey; armed with lots of great open source tools to automate every step of the way - but the writing code part ;)!

Spring I/O 2016 - 19 -20 May Barcelona The world at large seems sold on microservices as a way to build large, quality systems at the speed needed to compete in today's market. However, microservices are not without their downsides, one of which is the difficulty of reasoning about and optimising the performance of mircoservices working in tandem. In this session, attendees will learn the key concepts needed to measure the performance of their services, identify potential bottlenecks and take corrective action to ensure services perform as needed. Before we can reason about the performance of connected services, we must understand how to reason about services in isolation. The first half of the session is dedicated to discussing how to measure service performance correctly, what metrics matter and how to compare the performance of a service over time. In the second half of the session, we take our single-service knowledge and expand it out to reason about a set of services working together to provide some aggregate function. We'll see how the performance of each service affects the performance of the whole, and learn how to identify where to focus our optimisation efforts.

This is a simple developers log to keep me and my friend motivated. I've started a Java SE project to entartain myself and I figured I can make a simple, small game. I want to start with little steps to avoid any frustration. And I actualy want to have fun during the development. This is the current progress after few hours of programming/chatting/laughing. Workflow: 1. create a game engine 2. print a dot 3. antialiasing 4. move the dot (4 directions) 5. doublebuffering 6. add background so the dot doesn't leave a trail 7. diagonal movement 8. avoid key repeat delay Music: Battle of Kings, Infected Euphoria, Olympos (in that order) License: CC v3, https://machinimasound.com/license/ Author: https://machinimasound.com/

See http://javarevisited.blogspot.com/2011/07/java-debugging-tutorial-example-tips.html for more debugging tips on Eclipse IDE Ability to debug a java program is a great arsenal in a java developer's hand and an ultimate solution of any java problem. if you can debug your program remotely or locally you will be more confident about the changes you make in code. debugging is the process of analyzing the execution of the program on a step by step manner and identifying the bug or issue. Java provides lots of debugging options e.g. Java debugger also called JDB and Java IDE like Eclipse and Netbeans are simply great. I use Eclipse because of its seamless remote debugging feature which allows you to debug java program running on remote Linux machine.

The possibilities and advantages of non-blocking IO are great. But as you have to hassle with callbacks all over the place you have to think differently. Sometimes simple constructs we are used to are getting ugly or really hard to realize. A little bit of Groovy-magic can help out to simplify life and make your code more look like you are used to. This session whats to show experiences creating a vert.x-based application and the solutions we used to smooth up our code.

Eugene Platonov - Tracking with Writer Monad. ScalaUA2018 This talk will tell the story of one team at eBay which used to do data tracking in a healthy side-effecting manner. Until the Team realized that it’s not that healthy. Solution was found in a Writer Monad (residing in cats library) as well as in the fact that Writer Monad can stay in shades. Some people, especially whey they are new to typed FP, don’t like/feel comfortable to see words like Semigroup, Traversable, Writer and such in their domain code. The talk will show how those “scary” parts can be “hidden” by domain specific extension methods. Eugene Platonov - https://github.com/jozic Next ScalaUA Conference - March 29-30, 2019 in Kyiv, Ukraine. The Scala-Community-driven conference for developers https://scalaua.com Webinar.ScalaUA https://webinar.scalaua.com is a training platform for improving participants’ skills in Scala and JVM.
