Static (ahead-of-time) compilation of code appeared in Oracle JDK 9. We have already discussed why this is necessary, and the scope of the current implementation. Now it makes sense to talk about the technical details. Anyone can easily suffer from some already known problems of current implementation. From the other hand it makes sense to test potential benefits and to try a tiny piece of bright future. But one must realize how to try it right. What information is generated by the AOT and how it is generated, how compiled AOT code interacts with Hotspot. What you can do with AOT code by external tools, and how to infiltrate into the compilation process. And of course, what grips to twist, and what will be the performance with AOT.
Different Java implementations exist. Your code lives multiple lifes inside them and JIT compilers provide performance behind the scenes. Some JVMs have ahead-of-time (AOT) compilation that shortens the path. Statement of the problem is different, as well as solutions. Let's see why do we need pre-compiled code, how it can already be produced and used with Hotspot. How Project Graal lets Java to compile Java to native code and how new Java-Level JVM Compiler Interface incorporates Java to compilation work of JVM.
The document discusses CompletableFuture in Java and provides the following information:
- CompletableFuture allows composing asynchronous operations in a sequential manner without blocking threads. It implements Future and CompletionStage interfaces.
- The API includes methods for creating CompletableFutures, transforming results, error handling, combining results from multiple CompletableFutures, and retrieving final values.
- Benchmarks show CompletableFuture has lower overhead than using raw Future for simple asynchronous operations, especially when work is split across multiple threads.
Introduction to JavaFX on Raspberry PiBruno Borges
The document discusses using JavaFX to build applications on Raspberry Pi. It provides instructions on configuring the Raspberry Pi for JavaFX, including overclocking the CPU, allocating memory, and configuring the framebuffer. It also demonstrates how to create a basic JavaFX application for Raspberry Pi using FXML, properties, bindings, and threads. The document recommends libraries for using JAX-RS to interface with REST services and code examples of doing so.
The document discusses building a "carputer" system using a Raspberry Pi to monitor and display real-time data from a vehicle. It describes connecting various sensors like an accelerometer, GPS, and thermal sensors to measure metrics like acceleration, location, and brake/tire temperatures. The system runs a JavaFX user interface on the Raspberry Pi touchscreen to display live data, graphs, and other screens. The document outlines the hardware architecture and provides code examples for reading sensor data and displaying it in the carputer system.
In this presentation, we (Jonatan and Marco) investigated the new official and hidden features of Java 12.
We collected code examples and stories behind this release. We were happy about some features and disappointed with others.
We hope that with these slides you can learn quickly and with fun what's coming with the new version of Java.
The latest JDK 12 release cycle and the alter support model will exact quicker of previous version and latest features on a regular basis. In great combination with the evolution of previous frameworks.
This document discusses scalable JavaScript applications using Project Nashorn. It covers why JavaScript is useful for servers, benefits of the Java virtual machine, an overview of Nashorn and its capabilities, and how frameworks like Vert.x and Avatar.js allow building scalable architectures. It also includes a benchmark comparison and questions.
Is An Agile Standard Possible For Java?Simon Ritter
This document discusses how Java and the OpenJDK project have moved towards a more agile development process over time. It describes how the JDK Enhancement Proposal process was introduced in JDK 8 to allow for smaller pieces of work than a full Java Specification Request. This has enabled more frequent delivery of new features in point releases like JDK 8 and 9. However, integrating new APIs while maintaining compatibility with the specification and test compatibility kit remains a challenge. The document concludes that while Java has made progress in becoming more agile and open-source driven, challenges around standards and testing remain.

invokedynamic for Mere Mortals [Code One 2019]David Buck
The invokedynamic instruction (part of JSR 292) has been around since JDK7. Despite its importance to most languages that run on the JVM, many developers still do not understand how it is used or implemented. Most resources available about JSR 292 are aimed at language implementers who are experts in compiler theory and language design. This session is different, offering an overview of JSR 292 for people who are curious about how things work but do not necessarily spend all day working on java bytecode. This update of the speaker’s 2015 session on the same topic has been updated to include new uses and related changes since Java 8.
Are you interested into getting deep insight into the new features that Project Jigsaw offers in Java 9 ?
Project Jigsaw is one of the biggest changes introduced in Java since the launch of the Java programming language back in 1995. It has a great impact on the way we architect and develop Java applications.
Project Jigsaw represents a brand new modular system that brings lots of features and empowers developers to build modular applications using Java 9.
In this presentation you will see how the entire JDK was divided into modules and how the source code was reorganized around them.
You will learn all what you need to know in order to start developing reliable, secure and maintainable modular Java applications with Project Jigsaw.
You will see how to define modules and how to compile, package and run a Java application using Jigsaw.
You’ll learn how to take advantage of the new module path and how to create modular run-time images that represent smaller and compacter JREs that consist only of the modules you need.
Having a Java 7 or 8 application and you are intending to migrate it to Java 9? In this talk you’ll learn how to do it using top-down migration and bottom-up migration.
Are you afraid that your application code will break when switching to Java 9? No problem, you’ll see what you should do in order to make your application suitable for Java 9.
The document discusses what's new in Java 9. Key changes include the introduction of a module system that allows modularization of the Java platform and custom configurations. The tools javac, jlink and java now accept options to specify module paths. The JDK itself has been modularized. Most internal APIs are now inaccessible by default. The version string format was simplified. New tools introduced include JShell for REPL functionality and jlink to assemble custom runtime images. Enhancements were made for security, deployment, language features and streams.

Sergey Kuksenko talks about how (and how much) CPU microarchitecture details may have an influence on applications performance. Could it be visible by end-users? How to avoid misjudgment when estimating code performance? CPU is huge (not in size) that is why the talk is limited to those parts which located out of computational core (mostly caches and memory access). Filmed at qconsf.com.
Sergey Kuksenko works as Java Performance Engineer at Oracle. His primary goal is making Oracle JVM faster digging into JVM runtime, JIT compilers, class libraries and etc. His favorite area is an interaction of Java with modern hardware what he is doing since 2005 when he worked at Intel in Apache Harmony Performance team.

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.
When it is all about ERP solutions, companies typically meet their needs with common ERP solutions like SAP, Oracle, and Microsoft Dynamics. These big players have demonstrated that ERP systems can be either simple or highly comprehensive. This remains true today, but there are new factors to consider, including a promising new contender in the market that’s Odoo. This blog compares Odoo ERP with traditional ERP systems and explains why many companies now see Odoo ERP as the best choice.
What are ERP Systems?
An ERP, or Enterprise Resource Planning, system provides your company with valuable information to help you make better decisions and boost your ROI. You should choose an ERP system based on your company’s specific needs. For instance, if you run a manufacturing or retail business, you will need an ERP system that efficiently manages inventory. A consulting firm, on the other hand, would benefit from an ERP system that enhances daily operations. Similarly, eCommerce stores would select an ERP system tailored to their needs.
Because different businesses have different requirements, ERP system functionalities can vary. Among the various ERP systems available, Odoo ERP is considered one of the best in the ERp market with more than 12 million global users today.
Odoo is an open-source ERP system initially designed for small to medium-sized businesses but now suitable for a wide range of companies. Odoo offers a scalable and configurable point-of-sale management solution and allows you to create customised modules for specific industries. Odoo is gaining more popularity because it is built in a way that allows easy customisation, has a user-friendly interface, and is affordable. Here, you will cover the main differences and get to know why Odoo is gaining attention despite the many other ERP systems available in the market.
