Open Source Java Runtimes for Linux

RARS, the RISC-V Assembler, Simulator, and Runtime, will assemble and simulate the execution of RISC-V assembly language programs. Its primary goal is to be an effective development environment for people getting started with RISC-V.

GraalVM is a high-performance multilingual runtime. It is designed to accelerate the execution of applications written in Java and other JVM languages while also providing runtimes for JavaScript, Ruby, Python, etc. Increase application throughput and reduce latency. Compile applications into small self-contained native binaries. Seamlessly use multiple languages and libraries. Advanced optimizing compiler that generates fast lean code which requires fewer compute resources. Native binaries start up instantly and deliver peak performance with no warm up time. Leverage the best features and libraries of popular languages in a single app with no overhead. Debug, monitor, profile, and optimize resource consumption in Java and across multiple languages. Enterprise version provides all Community features along with higher performance and enhanced security. Additional ahead-of-time compilation optimizations and 24/7/365 support from Oracle.

Framework to implement board and card games including some already developed games. Typical game elements are offered by this library, so developers just care on the essential aspects that differ. Games created with tjger are also hosted (Four wins, Oasch, Schnapsen, Trap the Wizard, etc.) and the Tjger Game Pack contains all these games.

PEARL is a high level procedural programming language, which was especially designed for the demanding need to have an expressive and comfortable language for solving multitasking problems when controlling technincal processes. PEARL is an abbreviation for "(P)rocess and (E)xperiment (A)utomation (R)ealtime (L)anguage". It was designed around 1975 at the IRT Institute of the Leibniz University in Hannover with the idea in mind to have an easy to learn programming language for realtime problems. For more, also historical information please visit (http://www.pearl90.de/). In 1998 PEARL-90 was standardized by the Deutsches Institut für Normung e.V. in DIN 66253-2. PEARL provides the standard data types and structures known from other procedural languages like e.g. PASCAL. Additionally PEARL brings special language constructs for managing real-time and multitasking tasks.

QueryObjectFactory (QOF) is a lightweight runtime JDBC byte-code generator providing support for CRUD (create, retrieve, update and delete) operations and stored procedure calls. It uses Java annotations to define mappings and is fully OSGi ready.

Lightweight runtime monitor for AJAX web applications that checks in real time whether XML messages received and sent by the application satisfy a predefined interface specification. Complex message sequences and data values are supported.

Boot is a Clojure build framework and ad-hoc Clojure script evaluator. Boot provides a runtime environment that includes all of the tools needed to build Clojure projects from scripts written in Clojure that run in the context of the project. Build processes for applications always end up being complex things. A simple web application, for instance, may require many integrations–asset pipelines, deployment to different environments, the compilation of multiple artifacts with different compilers, packaging, etc. The more complex the build process becomes, the more flexible the build tool needs to be. Static build specifications become less and less useful as the project moves toward completion. Being Lispers we know what to do: Lambda is the ultimate declarative. Instead of building the project based on a global configuration map, boot provides a runtime environment in which a build script written in Clojure can be evaluated. It is this script.

JSchemePlus is an hack of Jscheme 1.4 by Peter Norvig. It allows to redistribute a script in an executable JAR file of only ~40K and implements all of R4RS with a lot of additional functions, like: (execute command) (random) (sequence from up-to step) (split list element) (string-split string sub-string) (read-all-from-file file) (write-to-file file data) (file-size file) etc... For the complete list read the HELP file or type (help). JSchemePlus needs only the Java Virtual Machine (version 6 or higher) that, in the case, is very easy to download and install.

Speedment is an open-source Java Stream ORM toolkit and runtime. The toolkit analyzes the metadata of an existing SQL database and automatically creates a Java representation of the data model. This powerful ORM enables you to create scalable and efficient Java applications using standard Java streams with no need to type SQL or use any new API. Speedment was originally developed by researchers and engineers based in Palo Alto with the purpose to simplify and streamline the development of Java database applications by leveraging the Java Stream API. Speedment is licensed under the business-friendly Apache 2 license. Contribution from users is encouraged. Please feel free to request new features, suggest improvements and file bug reports. Assuming you have Maven installed and a relational database available, you can start using Speedment in a minute. Automatic Java representation of the latest state of your database eliminates boilerplate code and the need of manually writing Java.

This library allows for the programmer to bind arbitrary properties to types which can be accessed at runtime via reflection. Properties can be declared via annotation and later manipulated through a simple static interface; no special naming conventions are required and the properties can be bound to any method which has the appropriate signature.
