    OpenJ9

    OpenJ9

    A Java Virtual Machine for OpenJDK

    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.

    JPHP

    JPHP

    JPHP - an implementation of PHP on Java VM

    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.

    X10

    Performance and Productivity at Scale

    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.

    Classic BCPL for the ATARI ST

    Classic BCPL for the ATARI ST

    BCPL was designed by Martin Richards at Cambridge University (1966)

    Here you will find a collection of BCPL tools I've gathered from the net, cleaned up and ported to the Atari ST. This involved fixing bugs, reducing stack usage and making the code compile in 16bit via Pure C (Turbo C for the Atari ST). Source credits include: Martin Richards - BCPL Kit http://www.cl.cam.ac.uk/~mr10/ Robert Nordier (Translated interp to C) http://www.nordier.com/ Serge Vakulenko (Translated cg/syn/trn to C) https://github.com/sergev/b I'm sure there are other names, but those are the ones on the source files. The code now compiles clean for the Atari ST, so it should work for anything else.
