XRuby is a Ruby to Java compiler that compiles Ruby source code to Java bytecode. It allows Ruby code to run on the Java Virtual Machine for improved performance over interpretation. The XRuby compiler consists of a parser that converts Ruby code to an AST, and a code generator that produces Java bytecode. It provides dynamic language support structures to handle Ruby classes and methods in Java. XRuby is still in early development but allows most Ruby code to run faster on the JVM and provides tools for contributors to help advance the project.

JRuby: What's Different (RORO Melbourne October 2011)Charles Nutter

JRuby runs Ruby code on the Java Virtual Machine. This allows Ruby programs to access Java libraries and tools like Swing, and take advantage of features like the JVM's garbage collection and just-in-time compilation. JRuby is compatible with Ruby 1.8.7 and 1.9.2 and runs on multiple platforms. While it has some missing or disabled features compared to MRI Ruby, JRuby programs typically see improved performance due to the JVM. JRuby also enables building scalable, concurrent server applications using Java servers and tools.

Inside the JVMJim Jagielski

The document discusses the Java virtual machine (JVM) memory layout and garbage collection. It explains that the JVM manages memory within a process heap. The Java heap stores Java objects and is configured using -Xmx and -Xms. Objects are initially allocated to the young generation and may be promoted to the old generation if they survive garbage collection. The JVM process heap also includes memory for permanent generation, threads, sockets, native code, and garbage collection itself. Out of memory errors can occur if any of these areas fill up. The document provides tips on tuning garbage collection and avoiding memory issues.

Python while loops (menard maranan)Menard Maranan

A while loop in Python is a type of loop that repeatedly executes a block of code as long as a given condition is true. It allows programmers to write code once that gets executed multiple times to save time, rather than writing the same code over and over. A while loop continues running its code block until the condition set for it becomes false, relying on boolean values of true or false to determine when to stop iterating.

Concurrency in rubyMarco Borromeo

This document summarizes Marco Borromeo's presentation on concurrency in Ruby. It discusses various approaches to achieving concurrency like multiple processes/forking, threads, and fibers. However, it notes that the global interpreter lock (GIL) prevents true concurrency in Ruby with threads and fibers. EventMachine and the reactor pattern provide an asynchronous approach using blocking I/O. EM-Syncrony and Sinatra::Synchrony build on this to provide a synchronous style of programming with concurrency.

The Dark Side Of Lambda Expressions in Java 8Takipi

This document discusses the "dark side" of Lambda expressions in Java 8. It notes that while Lambda expressions allow for more concise code, they can make debugging more difficult since the bytecode generated no longer closely matches the source code written. This is due to the JVM remaining oblivious to Lambda expressions. The distance between source code and bytecode is even greater for languages like Scala, JavaScript, and Nashorn, leading to longer, harder to understand call stacks when exceptions occur.

JRuby allows Java developers to use Ruby and benefit from Java libraries and platforms. It implements Ruby in Java, making Ruby code compatible with Java and allowing use of Java from Ruby. Ruby on Rails is a popular web framework for Ruby that emphasizes convention over configuration for high productivity web development with less code. JRuby enables using Rails with Java's deployment and library benefits and was demonstrated in a Netbeans IDE. More Ruby information can be found online at sites like JRuby.codehaus.org and rubyonrails.org.

Remote Method InvocationSonali Parab

Remote Method Invocation (RMI) allows objects running in one Java virtual machine to invoke methods on objects running in another Java virtual machine. RMI uses object serialization to marshal and unmarshal parameters and supports true object-oriented polymorphism. RMI is implemented using three layers - stub, remote reference, and transport connection layers. The stub and skeleton hide the underlying network implementation details and allow remote objects to be called similar to local objects. Security is an important consideration in RMI and a security manager must be installed and permissions configured to control access to remote objects and classes.

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

1. XRuby Enjoy Ruby on JVM Ye Zheng http://dreamhead.blogbus.com

2. Agenda What is XRuby XRuby Architecture XRuby Jump Start More on XRuby

3. Agenda What is XRuby XRuby Architecture XRuby Jump Start More on XRuby

4. What is XRuby XRuby is the first Ruby to Java compiler which compiles Ruby source code (.rb) to Java bytecode (.class). XRuby .rb .class

5. XRuby current status The latest version is 0.3.0. test::unit works. XRuby debugger provided Java to Ruby binding annotation. Runs most benchmark faster than ruby 1.8.6.

6. Two Ways to JVM(I) Interpretation current C Ruby way easy to port needs interpretation engine slow Ruby Script Parser AST

7. Two Ways to JVM(II) Compilation needs more explorations uses JVM as execution engine protects source code fast Ruby Script Compiler .class

8. Why Compilation is Faster Compilation is faster than interpretation JVM JVM Interpretation Engine Ruby Script Ruby Script Interpretation Compilation

9. Misunderstandings It erases dynamic language features. Dynamic structure written in Java is developed to support dynamic language features It maps Ruby class to Java class directly. Ruby class is a dynamic language structure, and it is different from Java class which is a static structure
