IBM is developing a just-in-time (JIT) compiler called Testarossa based on its Open Runtime (OMR) toolkit. The goal is to integrate the JIT compiler into MRI Ruby to improve performance without changing how MRI works. So far, the JIT supports most opcodes and can run Rails applications, but performance gains are modest. IBM hopes to collaborate with the Ruby community to further optimize Ruby and help make it faster.College Project - Java Disassembler - Description

JSR 292 introduces a new Java bytecode instruction, invokedynamic, and a new dynamic method linkage mechanism using method handles to better support dynamically typed languages on the JVM. The invokedynamic instruction and method handles allow linking of method calls without specifying the target type at compile time. A bootstrap method is called during linking to choose an appropriate method handle for each invokedynamic call site. This new approach addresses issues dynamically typed languages faced in meeting the static typing requirements of regular JVM bytecode instructions. Future enhancements may include structured ways to modify classes at runtime through interface injection.NDK Primer (Wearable DevCon 2014)

The document discusses caching and synchronization of server data across multiple views and users in Flex applications. It proposes storing all fetched entities from the server in a single cache, binding views to the cache, and updating views when the server sends a notice that an entity has changed. When an entity is requested but not in the cache, a wrapper object is returned and the entity is queued to be fetched. The approach requires unique entity keys, abilities to get entities by key or keys, and support for versioned entities on the server-side.Visage Android Hands-on Lab (OSCON)

You suck at Memory AnalysisFrancisco Ribeiro
油
From the current offensive and defensive technique arsenal, memory analysis applied to volatile memory is far from being the most explored channel. It is more likely to hear about input validation attacks or attacks against the protocol & cryptography while keys, passphrases, credit card numbers and other precious artifacts are kept unsafely in memory. This analysis arises as a mine waiting to be explored since it is sustained by one of the most vulnerable and unavoidable resource to systems, memory. From Java to Stuxnex, as well as Windows but without forgetting the Cloud, I will try to show some scenarios where these techniques can be applied, its impact as a threat and bring an important and fun subject not just to those who work in forensics but also to penetration testers as myself. Finally, I will also try to show how can this be used for defensive technologies as tools for monitoring and protection in networks with systems in production.Method Handles in Java
Method Handles in Javahendersk
油
This document discusses method handles and lambda expressions in Java 8. It explains that method handles are references to methods that can be executed and are obtained through reflection. Method handles improve on reflection by caching access at lookup rather than invocation time. Lambda expressions allow anonymous blocks of code and are implemented using invokedynamic and method handles. When the compiler encounters a lambda expression, it is "desugared" into a private method and an invokedynamic instruction generates an instance of a functional interface to reference the lambda expression.Inside the JVM - Follow the white rabbit! / Breizh JUG

How do we go from your Java code to the CPU assembly that actually runs it? Using high level constructs has made us forget what happens behind the scenes, which is however key to write efficient code.
Starting from a few lines of Java, we explore the different layers that constribute to running your code: JRE, byte code, structure of the OpenJDK virtual machine, HotSpot, intrinsic methds, benchmarking.
An introductory presentation to these low-level concerns, based on the practical use case of optimizing 6 lines of code, so that hopefully you to want to explore further!

JRuby allows running Ruby code on the Java Virtual Machine. It has the advantages of accessing Java libraries from Ruby and embedding Ruby in Java applications. Gems mostly work the same in JRuby as Ruby MRI, though some with native extensions may need alternatives. ActiveRecord can use JDBC drivers in JRuby to connect to databases. Converting Rails apps may require updating gems to specify platforms. JRuby is well-suited for deployment on Java application servers using WAR files generated by the Warbler gem.jRuby: The best of both worlds

Ruby's method_missing method allows developers to override Ruby's default method lookup behavior when a method is not found. This is commonly used to create domain-specific languages in Ruby. When Ruby cannot find a method, it will call method_missing as a last resort. Developers can define method_missing to customize what happens in this case.The Breakthroughs

Cloud Computing is rapidly evolving the hosting marketplace with the big vendors seemingly eating into the supply chain setting up their own data centers and selling Cloud services direct to the customer. Yet dig beneath the surface and the Channel still has enormous value to add, it's just different to before. Cloud Aggregation represents the fastest single growing segment according to the latest Gartner research- so partnering with ISV's represents a massive potential growth area. Adding and bundling Cloud services can transform low margin capital intensive businesses into much more profitable ones. But not all Clouds are created equal, with organizations having Security, Data Protection, Proximity and Sovereignty concerns; Hosters have a massive opportunity to offer differentiated services and need not compete on price. Anders Trolle-Schultz and Justin Pirie, SaaS and Cloud Experts, will set the scene and take you through the journey of the new Cloud ecosystem and the roles the traditional Hoster can take in the emerging Cloud marketplace.College Parents Humor: From Acceptance through Move-In

This document provides 45 short lessons on life. Some of the key lessons include: have a positive attitude as life isn't always fair but it's still good; take things one small step at a time when in doubt; and don't waste time hating others as life is too short. Additional lessons advise paying off credit cards each month, making peace with the past so it doesn't affect the present, and choosing to be happy as that is under your control rather than comparing yourself to others. The overall message is that having the right attitude can help one better deal with life's ups and downs.Similar to Intro to J Ruby (20)

The document discusses JRuby, which is a Java implementation of the Ruby programming language. JRuby allows Ruby code to leverage Java libraries and infrastructure and run on the Java Virtual Machine. It provides benefits like running the same code on all platforms and leveraging existing Java skills and tools. However, it also has drawbacks like a larger memory footprint compared to other Ruby implementations. The document provides examples of using JRuby for web applications, system integration projects, and describes some organizations that use JRuby in production.Monkeybars in the Manor

JRuby is an implementation of the Ruby language that runs on the Java Virtual Machine. It allows Ruby code to access Java libraries and APIs and Java code to call Ruby methods. Some benefits of JRuby include access to mature and stable Java platforms, libraries, and tools as well as improved performance from features like garbage collection. JRuby also allows Java shops to introduce scripting and Ruby skills.JRuby Basics
