GNU Classpath - Mother of most of the VM

  •        3695

GNU Classpath provides core class libraries for use with virtual machines and compilers for the java programming language. GNU Classpath 1.0 will be fully compatible with the 1.1 and 1.2 API specifications, in addition to having significant compatibility with the 1.3, 1.4, 1.5 and 1.6 APIs.

It is the mother of most of the JVMs. Check out the list of other Virtual Machine products using GNU Classpath as its base. Intel and IBM are using GNU Classpath in their research

DataScienceVM - Tools and Docs on the Azure Data Science Virtual Machine (http://aka.ms/dsvm)


The Data Science Virtual Machine (DSVM) is a customized VM image on Microsoft’s Azure cloud built specifically for doing data science. It has many popular data science and other tools pre-installed and pre-configured to jump-start building intelligent applications for advanced analytics. It is available on Windows Server 2016, Windows Server 2012, and on Linux. We offer Linux edition of the DSVM in either Ubuntu 16.04 LTS or on OpenLogic 7.2 CentOS-based Linux distributions. You can try the Data Science VM for free for 30 days (with $200 credits) with a free Azure Trial. The Linux (Ubuntu-based) DSVM also provides a test drive through a button on the product page. The Test Drive will provide full access to you own instance of the VM with just a free Microsoft account (No Azure subscription or CC needed).On this repo, we will feature tools, tips and extensions (see below) to the Data Science VM. We invite the DSVM user community to contribute any useful tools or scripts, extensions you may have written to enhance the user experience on the DSVM.
