Nashorn: JavaScript that doesn’t suck (ILJUG)
View the video (in Hebrew) on Parleys: http://www.parleys.com/play/537f3dade4b0e9793767cd35
Java 8 introduces a new JavaScript engine called Nashorn. This presentation gives an overview of the new engine, provides some historical context and dives into the implementation details.
Originally presented at the Israeli Java User Group (ILJUG) Java 8 launch event on April 28th, 2014.
Server-Side JavaScript with Nashorn
Server-Side JavaScript with Nashorn
Nashorn is a JavaScript engine that runs on the Java Virtual Machine (JVM), allowing for server-side JavaScript. It provides full ECMAScript 5.1 compliance and interoperability with Java libraries and frameworks. Nashorn performance is improving with recent Java updates and will soon reach near-native levels, making the JVM a platform for high-performance dynamic languages like JavaScript on the server-side.
Lagergren jvmls-2013-final
The document discusses challenges in implementing a dynamic language like JavaScript on the Java Virtual Machine (JVM). Some key points:
- Nashorn is a JavaScript runtime written in Java that generates JVM bytecode, aiming to be 2-10x faster than previous solutions like Rhino.
- Compiling JavaScript to JVM bytecode is difficult as JavaScript has dynamic types, runtime changes, and number representations that don't map cleanly to Java's static types.
- Nashorn uses static analysis to infer types where possible and optimize for primitive number representations, but this only goes so far with JavaScript's dynamic nature.
- As JavaScript code changes, Nashorn may need to transition to more dynamic, adaptive and optimistic techniques
GitBucket: The perfect Github clone by Scala
GitBucket is an open-source GitHub clone written in Scala that provides features like public and private repositories, wiki, issues, pull requests, and more. It uses Scala web frameworks like Scalatra and Twirl for the backend and JVM technologies like JGit, H2 database, and Apache MINA for key functions. GitBucket aims to be easy to install, run purely on the JVM, and provide an alternative for those unable to access GitHub due to political restrictions.
Java/Spring과 Node.js의 공존 시즌2
This document discusses strategies for using Node.js alongside Java/Spring applications. It introduces J2V8, which allows running Node.js modules and the V8 JavaScript engine in Java. Examples are given for isomorphic React rendering using Nashorn or Node.js. The document also covers using Nashorn or script templating engines like EJS directly in Spring MVC. Performance benchmarks show J2V8 templating is faster than traditional Java approaches like JSP or Thymeleaf. Source code examples demonstrate setting up J2V8 with Spring Boot for building isomorphic web applications that leverage both Java and JavaScript.

It then discusses Rhino, an early JavaScript engine implemented in Java that compiles JavaScript to Java bytecodes slowly. Nashorn, introduced in Java 8, is 20x faster than Rhino as it compiles JavaScript directly to bytecodes without an intermediate compilation step. Nashorn also improves type handling and has a smaller memory footprint than Rhino. The document demonstrates key features of Rhino and Nashorn like script evaluation, function invocation, and lambda expressions.
Java script at backend nodejs
This document outlines an agenda for discussing JavaScript at the backend using Node.js. The agenda includes explaining what Node.js is, installing Node.js, writing a simple "Hello World" program, running Node.js applications, exploring core Node.js modules like the file system and HTTP modules, and handling HTTP requests. Key points are installing Node.js from its website, using the file system and HTTP modules to interact with files and create an HTTP server, and using a request handler to return different responses based on the URL. The presenter is introduced as an author who works with JavaScript, Node.js, and related technologies.
Introduction to Node js
The document provides an introduction to building a simple web server in Node.js. It discusses organizing the code into modules, including a server module to start the web server, a routes module to route requests, and a request handlers module. It also covers basic concepts like using the http module to create a server, handling requests, and returning responses. The server currently returns the same "Hello World" response for all requests, and next steps involve routing requests to proper handlers to return the appropriate content based on the URL.
NodeJS ecosystem
Node.js is well-suited for applications that require lightweight concurrency and asynchronous I/O. It uses an event-driven, non-blocking model that makes it efficient for real-time applications with high concurrency needs, such as chat, live data feeds, and web site monitoring dashboards. While Node.js performs well for lightweight operations, heavier CPU-intensive tasks may be better suited for Java/J2EE due to its multi-threading capabilities. The Node.js ecosystem is growing rapidly but still less mature than Java/J2EE's established ecosystem.

OCA Java SE 8 Exam Chapter 2 Operators & Statements
Operators in Java include unary, binary, and ternary operators that perform operations on operands. Binary operators like arithmetic, relational, and logical operators follow an order of precedence unless overridden by parentheses. Statements in Java include if-then, if-then-else, switch, while, do-while, for, and more to control program flow. The if-then statement and if-then-else statement evaluate conditions and execute code blocks conditionally. The switch statement compares a value to multiple case labels and executes the corresponding code block.

This document discusses Java 8 concurrency abstractions including asynchronous result processing using CompletableFuture and optimistic locking using StampedLock. It provides an overview and comparison to previous concurrency APIs. The agenda includes exploring CompletableFuture features like asynchronous execution, chaining reactions, and exception handling. It also covers using StampedLock for optimistic reads, comparing it to the previous ReentrantReadWriteLock approach. Examples are shown for common use cases of these new concurrency APIs.
Effective java
The document provides guidelines for implementing common object-oriented methods in Java, such as equals(), hashCode(), and constructors, to ensure they behave properly. Some key points discussed include: when to override equals() and how to ensure it obeys the general contract; how to implement hashCode() whenever equals() is overridden; using static factory methods or builders instead of constructors when there are many parameters; and avoiding finalizers due to performance and reliability issues. Immutable classes, singletons, and non-instantiability are also addressed.
Java static keyword
The document discusses the static keyword in Java. It explains that static members belong to the class rather than objects, and are loaded when the class is loaded. Static variables and methods can be accessed without creating an object. Constructors are used to initialize non-static variables when an object is created. Static blocks run when the class is loaded and can initialize static variables.

Similar to Nashorn
Nashorn
Nashorn is the JavaScript engine that replaced Rhino in Java 8. It provides better performance than Rhino by compiling JavaScript to Java bytecode rather than interpreting it. Nashorn allows embedding JavaScript in Java applications and developing standalone JavaScript apps. It features interoperability between Java and JavaScript, is embeddable in Java without external libraries, and compatible with ECMAScript 5.1 specifications. However, it only supports features up to ECMAScript 5.1 and lacks a browser plug-in API or DOM/CSS support.

Java 8 JavaScript – Nashorn by Miroslav Rešetar
Java 8 donosi podršku za scripting u JavaScriptu. Engine se zove Nashorn (openjdk.java.net/projects/nashorn) i nasljednik je popularnog Rhino engine-a. Za razliku od starijeg Rhino-a, Nashorn koristi invoke dynamic Java 7 mehanizam što mu omogućava puno bolje performanse. Nashorn je moderni engine, usklađen sa ECMAScript 5.1 standardom. To omogućava uporabu popularnih JavaScript biblioteka iz Java programa što otvara neke sasvim nove načine kako implementiramo naša Java rješenja. Prezentacija ima za cilj upoznati Java developera s mogućnostima integracije JavaScript-a u buduća Java 8 rješenja.Top 50 Node.js Interview Questions and Answers | Edureka

Node4J: Running Node.js in a JavaWorld
Node.js and server side JavaScript are powerful technologies, although they do not stand on their own in enterprise environments, where Java has been the reigning force for many years. Bridging Node.js and Java provides a much sought after migration path for many Java developers who are moving to their systems to JavaScript. Last year we opened sourced J2V8, a rich set of bindings for Google's V8 JavaScript runtime, this year we built upon that work to bring Node.js to JVM.
In this talk we will introduce Node4J, our NodeJS bindings for the JVM and demonstrate it in action. We will explore the performance characteristics and highlight tools that will help you develop, debug and deploy NodeJS applications running directly on the JVM. We will explain how we integrated NodeJS, with Java through a JNI bridge, and demonstrate how you can use this technology to bridge the gap between JavaScript and Java.

Kustomize aims to provide a simpler way to customize configurations and can integrate with tools like ArgoCD. Challenges include dealing with incompatible upstream changes and difficulties reviewing pull requests.
Intro to InnerSource
Slides from Daniel Figucio, Field CTO at Github APAC from his talk at Wellington DevOps Group on 6 September, 2022
https://www.meetup.com/wellington-devops-group/events/287973178/
Adopting this modern approach to software development can be transformative—enabling collaboration and fostering the creation of high quality code. But understanding the principles, and potential challenges, is critical to success.
Many companies use the word “innersource” to describe how their engineering teams work together on code. Innersource is a development methodology where engineers build proprietary software using best practices from large-scale open source projects, like Kubernetes or Microsoft’s Visual Studio Code.
Large-scale open source projects require coordination and teamwork across thousands of contributors. The most successful ones are driven by a vision for their future, in addition to day-to-day user needs: speed, reliability, and functionality. The scale at which these operate can teach us a few lessons—and help your business build better software, faster using innersource.

Safelyio Toolbox Talk Softwate & App (How To Digitize Safety Meetings)
Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/
