Crontab with configurable disk space autoprovision, set the room you want to reserve for your backups and rotate them. Full backups may be done with vmkfstools or by means of Rsync and its Delta algorithm (read: https://33hops.com/blog_xsibackup-rsync-considerations.html), to a local datastore or over TCP/IP tunneled through SSH, so any transfer over IP is secure.
Extrasphere is a set of tools for managing VM data in vSphere environments, including VM migration, proxy VMFS and hot mirroring. VM migration. Extrasphere provides unique technology of VM disks and configuration migration without downtime for a standalone VMware ESXi 5.5-6.5 host. Proxy VMFS. Proxy VMFS allows to access a local datastore of one ESXi host from another ESXi host remotely over NFS. This unique technology allows direct interaction with VMFS file system through hypervisor VMkernel, providing best performance. "HotMirror". It's better than VM replication - it's a mirror! The purpose of this feature is to get a mirror (duplicate) virtual machine on the same or different ESXi 5.5-6.5 host for the protected machine. Standalone "ESXi Hypervisor" (free) hosts are also supported.
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.

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.
Innovative and practical general-purpose multi-paradigm language
The Ring is an Innovative and practical general-purpose multi-paradigm language. The supported programming paradigms are Imperative, Procedural, Object-Oriented, Functional, Meta programming, Declarative programming using nested structures, and Natural programming. The language is portable (Windows, Linux, macOS, Android, etc.) and can be used to create Console, GUI, Web, Games and Mobile applications. The language is designed to be Simple, Small, Flexible and Fast.
Serpent is a real-time scripting language inspired by Python but completely reimplemented to support real-time garbage collection and multiple instances of the virtual machines running on independent threads.
Embedded by examples
Building of embedded systems from scratch including their cross-toolchain and using virtual and/or emulated machines as pratical examples.
A BASIC interpreter and compiler with graphics.

Command Script 4 (CSC4) is an "application control" or application extension scripting language / virtual machine / compiler environment. CSC4 supports object member access, object creation and static calls to the underlying .NET Framework 2.0.
Apple IIe emulator for Palm OS. Appalm uses uses certain techniques to improve performance which subvert some of the standard protection mechanisms of Palm OS. Appalm should not be used on machines with important data.
An object-oriented script language to embed in any application
A general purpose, object-oriented script language that compiles into code for a register based virtual machine. The language is quite similar to object-oriented high-level languages like Java and C#. The library is entirely self-sufficient and ANSI C compliant. It's main purpose is to be embedded in any application to allow automation of that application through scripting. An integrated C++ binding code generator allows you to create bindings for your application's classes in seconds. The integrated HTML documentation generator allows you to create documentation for your native bindings in seconds. The project is released under the zlib/libpng license. It has been in development for over 10 years and offers some powerful features. Extensive information, documentation, articles and code examples can be found at the developer blog.
Just emulating PowerPC processor through QEMU.
This is simple PowerPC emulation through QEMU emulator.
A client for administering VirtualBox and it's guests on a server
RemoteBox is a VirtualBox client. In essence, you can remotely administer (ie over the network) an installation of VirtualBox on a server, including its guests and interact with them as if they were running locally. VirtualBox is installed on 'the server' machine and RemoteBox runs on 'the client' machine. RemoteBox provides a complete GTK graphical interface with a look and feel very similar to that of VirtualBox's native GUI. If you're familiar with other virtualization software, such as VMWare ESX, then think of RemoteBox as the "poor man's" VI client.
PPface is vector processor emulator / simulator
PPface is vector processor emulator / simulator (SIMD array processor with 1-bit processing elements). VEPRAN language used to design parallel algorithms and operate data slices. The system allows to visualize algorithm work by viewing vector memory and registers, it supports debugging and animated program execution. To run this app on 64-bit system please install Windows Virtual PC and Windows XP Mode.
Emulator of the ancient 8 bit microprocessor SC/MP 2
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! The C cross-compiler, written in Java, directly compiles C Code into SC/MP machine code. It follows the classical LL(1) recursive-descent approach and makes usage of the emulator math and I/O libraries. Have fun, Theo Heinrichs
