GraalVM can be used as a drop-in replacement for the JDK to run Java programs. It includes the Graal just-in-time compiler which can provide better performance than the default HotSpot compiler. GraalVM also includes the native-image tool which can compile Java bytecode ahead-of-time to native executables without dependencies, improving startup time significantly. This enables using Java for more dynamic workloads like microservices that require fast startup. Reflection and dynamic proxies require additional configuration for native images. Docker images can also be built from native executables to distribute applications.
This document summarizes Clay Smith's talk on JavaScript development workflows and build tools. It discusses the many competing JavaScript frameworks, build tools, programming languages, and dependency managers. It also describes challenges with managing dependencies and build artifacts across platforms like mobile, and proposes using GitHub's Release API to store compiled build artifacts as a solution to avoid checking transformed code into version control.
How and why GraalVM is quickly becoming relevant for you (DOAG 2020)Lucas Jellema
Starting a Java application as fast as any executable with a memory footprint rivaling the most lightweight runtime engines is quickly becoming a reality, through Graal VM and ahead of time compilation. This in turn is a major boost for using Java for microservice and serverless scenarios. The second major pillar of GraalVM is its polyglot capability: it can run code in several languages - JVM and non-JVM such as JavaScript/ES, Python, Ruby, R or even your own DSL. More importantly: GraalVM enables code running in one language to interoperate with code in another language. GraalVM supports many and increasingly more forms of interoperability. This session introduces GraalVM, its main capabilities and its practical applicability - now and in the near future. There are demonstrations of ahead of time compilation and runtime interoperability of various non-JVM languages with Java.
- Java was originally developed by Sun Microsystems in the early 1990s and was designed to be a simple, object-oriented, robust, secure, portable, high-performance, multithreaded and dynamic language.
- Key features include being platform independent via bytecode, having a robust runtime environment in the Java Virtual Machine, and being object-oriented which makes Java code reusable and extensible.
- Java tools include a JDK for development and a JRE for running programs, with the JRE containing the Java Virtual Machine to interpret bytecode and class libraries.
Micronaut is a framework for building microservices that uses compile-time dependency injection and supports reactive programming and cloud native features. It can be used with GraalVM, an open source project that compiles Java applications ahead-of-time to native images for faster startup times and reduced memory usage. Together, Micronaut and GraalVM provide a lightweight and high-performance solution for building microservices that is well-suited for cloud environments.
Efficient DevOps Tooling with Java and GraalVMQAware GmbH
The document discusses using Java and GraalVM to build efficient DevOps tooling.

HOW TO CREATE AWESOME POLYGLOT APPLICATIONS USING GRAALVMOwais Zahid
Key to creating world-class solutions lies in the effectivity of cross-team collaboration and lead time. When multiple teams involved in a project, it is critical to take cross-platform and cross-language aspects into account. Introducing GraalVM, a universal virtual machine created to address an issue of teams struggling to collaborate because of varying preference of programming languages.
In this session, we will look at how you can use GraalVM to create polyglot applications with ease. It is a hands-on live coding session where we will look at Ruby, NodeJS & Java interoperability.
1) There are two main options for cross-platform mobile development: developing native apps separately for each platform or using a cross-platform development environment.
2) Cross-platform environments allow developing once and running on multiple platforms but have limitations including slower performance and inability to fully match native user interfaces.
3) For business apps, cross-platform may be suitable for simpler apps but has challenges supporting interface trends and speed. Games have fewer interface requirements and compilation can help speed but performance still lags native.
How fast can you onboard a new team member with VAGRANT ?Vivek Parihar
As the number of developers on a project, the number of projects in an Organization, or the complexity of a single project increases, it also becomes increasingly difficult to keep our development environments operational. From changing dependencies and differing server versions to running completely different operating systems specially windows machines of FrontEnd team, keeping the process of getting a running development environment sane and repeatable is non-trivial.
Getting the development environments identically setup can be a huge undertaking. On top of that, some people use Mac while others Use Linux or Windows. Before you know it, developers will be throwing computers through walls exhausted from constantly configuring and configuring. Windows machine devs yelling WTF is this Imagemagick , people using Mac asking which is better macports vs homebrew vs fink.
Vagrant solves all of this by introducing a common configuration format and workflow for describing and building development environments repeatably across Mac OS X, Windows, or Linux.
Java was created by James Gosling and his team at Sun Microsystems in 1991. It was originally designed for television but later shifted focus to use on the Internet when released in 1996. Java applications are compiled to bytecode that can run on any Java Virtual Machine, making code portable across platforms. Key features of Java include its simplicity, object-oriented design, security, and ability to write code once and run it anywhere. It differs from C/C++ in its removal of pointers and inclusion of automatic memory management through garbage collection.
Java has become popular due to its design features that allow programs to run on any platform. It is simple, object-oriented, distributed, interpreted, robust, secure, architecture-neutral, portable, high-performance, multithreaded, and dynamic. Java simplifies programming by eliminating pointers and multiple inheritance found in C++. It is inherently object-oriented and focuses on creating, manipulating, and connecting objects. Java also makes distributed computing easy by integrating networking capabilities.

This document provides an overview of 11 programming trends that are changing how developers work:
1. The Java Virtual Machine (JVM) is being used by many languages beyond just Java through cross-compilation, like Ruby, Scala, and Groovy.
2. Similarly, JavaScript is being used beyond just JavaScript through languages that cross-compile to JavaScript like Google Web Toolkit (GWT) and CoffeeScript.
3. There is a rise in "walled gardens" or tightly controlled development platforms like Apple's App Store and Facebook apps that limit developers' freedom.
4. Code is increasingly being developed as modules or snippets that integrate into frameworks rather than standalone programs, challenging traditional notions of ownership
GraalVM is a universal virtual machine that allows applications written in Java and other languages like JavaScript, Python, Ruby, and R to be compiled into self-contained binaries. This improves performance by reducing startup time and memory usage compared to the traditional JVM. The main features of GraalVM include a modern compiler that converts bytecode into native images, polyglot interoperability between multiple languages, and the ability to implement custom languages. While Scala Native is a competitor that focuses on optimizing Scala code ahead of time, GraalVM supports a wider range of languages and has a larger community behind it.
This document discusses how hackers can break CI/CD infrastructure by exploiting vulnerabilities at different stages of the software development process. It outlines attacks such as inserting malware in source code or libraries, exploiting privileged access in build pipelines to achieve remote code execution, deploying zip bombs or memory bombs to crash systems, and compromising shared infrastructure between development and production environments. The document emphasizes the importance of limiting permissions, isolating networks, monitoring for anomalies, and hardening CI/CD systems with the same care as production servers.
This document discusses security concerns related to continuous integration and continuous delivery (CI/CD) pipelines.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
