Byte Buddy is a code generation and manipulation library for creating and modifying Java classes during the runtime of a Java application and without the help of a compiler. Other than the code generation utilities that ship with the Java Class Library, Byte Buddy allows the creation of arbitrary classes and is not limited to implementing interfaces for the creation of runtime proxies. Furthermore, Byte Buddy offers a convenient API for changing classes either manually, using a Java agent or during a build. In order to use Byte Buddy, one does not require an understanding of Java byte code or the class file format. In contrast, Byte Buddy's API aims for code that is concise and easy to understand for everybody. Nevertheless, Byte Buddy remains fully customizable down to the possibility of defining custom byte code. Furthermore, the API was designed to be as non-intrusive as possible and as a result, Byte Buddy does not leave any trace in the classes that were created by it.

JPPM is a packager manager for JPHP like npm or composer. JPPM will help you to build and run jphp applications or write new packages. JPHP is a new implementation for PHP which uses the Java VM. It supports many features of the PHP language (7.1+). How does it work? JPHP is a compiler like javac, it compiles PHP sources to JVM bytecode and then can execute the result on the Java VM. We develop a new IDE for beginners like Game Maker or Scirra Construct. It's based on JPHP, JavaFX, Java 8, and Gradle, and allows to creation of desktop games and apps for Linux, Windows, and Mac (maybe Android and other platforms in the future). JPHP is not a replacement for the Zend PHP engine or Facebook HHVM. We don’t plan to implement the zend runtime libraries (e.g. Curl, PRCE, etc.) for JPHP. PHP 7.1+ (and many language features from PHP 7.2, 7.3, 7.4). JIT (~2.5x faster PHP 5.6, ~1.1x faster PHP 7.0, ~13% slower than PHP 7.4, bench). Using java libraries and classes in PHP code.

A Java Virtual Machine for OpenJDK that's optimized for small footprint, fast start-up, and high throughput. Builds on Eclipse OMR and combines with the Extensions for OpenJDK for OpenJ9 repo. We're not sure which route you might have taken on your way here, but we're really pleased to see you! If you came directly from our website, you've probably already learned a lot about Eclipse OpenJ9 and how it fits into the OpenJDK ecosystem. Eclipse OpenJ9 is an independent implementation of a Java Virtual Machine. "Independent implementation" means it was built using the Java Virtual Machine specification without using any code from any other Java Virtual Machine. The OpenJ9 JVM combines with the Java Class libraries from OpenJDK to create a complete JDK tuned for footprint, performance, and reliability that is well suited for cloud deployments. The original source contribution to OpenJ9 came from the IBM "J9" JVM which has been used in production by thousands of Java applications.

This is an x86 emulator written in pure Java based on the Dosbox project. It currently supports running Dosbox's built in DOS and well as booting into Windows 95/98/NT4.

JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.

VMware Tools Client allow you to execute scripts and transfert files on vSphere Virtual Machines through VMware Tools. http://pierrelx.com/vmware-tools-client Main features: - Commands / Scripts execution - Scripts stored in exportable ".db" file - Download file from virtual machines - Upload file to virtual machines - Ping test - Communicates with Virtual Machines only with VMware tools - Read only on vCenter API to discover inventory (will not scan the entire vCenter, it is live discovery) - vCenter URL/Login and Virtual Machine credentials stored in separeted and exportable ".db" file - Linux / Windows support - Multi VM view - JavaFX user interface

Execute Java code like java.exe 1. support service to start/stop 2. support console command to execute java

A open source java card virtual machine implementation. And also some part of the VM code can be used as part of kinds of tools such as javacard bytecode disassembler.

raw2vmdk is an OS independent Java utility that allows you to mount raw disk images, like images created by "dd", using VMware, VirtualBox or any other virtualization platform supporting the VMDK disk format.

X10 is a class-based, strongly-typed, garbage-collected, object-oriented language. To support concurrency and distribution, X10 uses the Asynchronous Partitioned Global Address Space programming model (APGAS). This model introduces two key concepts -- places and asynchronous tasks -- and a few mechanisms for coordination. With these, APGAS can express both regular and irregular parallelism, message-passing-style and active-message-style computations, fork-join and bulk-synchronous parallelism. Both its modern, type-safe sequential core and simple programming model for concurrency and distribution contribute to making X10 a high-productivity language in the HPC and Big Data spaces. User productivity is further enhanced by providing tools such as an Eclipse-based IDE (X10DT). Implementations of X10 are available for a wide variety of hardware and software platforms ranging from laptops, to commodity clusters, to supercomputers.

Fully graphical mips simulator, with a simple text editor. The aim is to not only have the entire mips isa implemented and simulated, but to have a mips ide. The text highlighting for the mips instructions set is currently underway. Version 3 Available.

Emulator of the ancient 8 bit microprocessor ISP-8A 500D/600D or more common "SC/MP" from National Semiconductor. The download contains all sources plus an executable Java Jar file to start right away. Some SC/MP hex dump examples are provided in directory "/etc" as well. The download also contains unit tests and some helping documentation (also in /etc). You may slow down the CPU operations, displaying the CPUs status register as LEDs, to watch the CPU working with its registers. The emulator also contains a VDU (video display unit) output / ASCII input simulation. There are some demos in /etc. And have a look to the NIBL / TINY BASIC interpreter in the TINYBASIC folder, most of the code is over 40 years old. Have fun, Theo Heinrichs
