Urbit
An operating function
Urbit is a personal server stack built from scratch. It has an identity layer (Azimuth), virtual machine (Vere), and operating system (Arvo). A running Urbit "ship" is designed to operate with other ships peer-to-peer. Urbit is a general-purpose, peer-to-peer computer and network. Urbit is for everyone, but sometimes it is easy to get lost in this universe. It solves the hard problems of implementing a peer-to-peer network (including identity, NAT traversal, and exactly-once delivery) in the kernel so app developers can focus on business logic. ... -

VirtualBox
Virtualization software for x86_64 hardware
VirtualBox is a powerful open-source full virtualization software that allows a user to run one or more “guest” operating systems simultaneously inside “virtual machines” on a single physical “host” machine. It supports a wide variety of host platforms (Linux, Windows, macOS, Solaris, etc.) and guest OSes, enabling, for example, running Linux on a Windows PC, running Windows Server on a Linux host, or even legacy OSes in a controlled environment. This flexibility makes VirtualBox ideal for developers, testers, sysadmins, or hobbyists who need different OS environments, want to test software across systems, or need isolation for development, sandboxing, or security experiments. ... -

stress-ng
This is the stress-ng upstream project git repository.
This is the stress-ng upstream project git repository. stress-ng will stress test a computer system in various selectable ways. It was designed to exercise various physical subsystems of a computer as well as the various operating system kernel interfaces. stress-ng was originally intended to make a machine work hard and trip hardware issues such as thermal overruns as well as operating system bugs that only occur when a system is being thrashed hard. Use stress-ng with caution as some of the tests can make a system run hot on poorly designed hardware and also can cause excessive system thrashing which may be difficult to stop. -

Cosmopolitan
Build-once run-anywhere c library
Cosmopolitan Libc makes C a build-once run-anywhere language, like Java, except it doesn't need an interpreter or virtual machine. Instead, it reconfigures stock GCC and Clang to output a POSIX-approved polyglot format that runs natively on Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS with the best possible performance and the tiniest footprint imaginable. Cosmopolitan can be compiled from source on any Linux distro. GNU make needs to be installed beforehand. ... -

ravynOS
A BSD-based OS project that aims to provide an experience with MacOS
...So we are creating ravynOS, an OS aimed to provide the finesse of macOS with the freedom of FreeBSD. This is a developer preview image that’s mainly intended for helping build the system. We recommend running in a virtual machine, although it should work on any hardware supported by FreeBSD-CURRENT (14.0) with at least 2GB (8GB recommended) RAM. PLEASE NOTE: On 2022-02-14, we decided to abandon the current path of using X11/KDE desktop components and write from scratch a new UI that will align better with our goals. This stepping back will slow the project but ultimately should result in a better outcome. ... -

denuvo
DENUVO (VMProtect 2.6x) VM research tool
This is part of the original source code of DENUVO_Profiler, written by 386 Team in 2014-2017 to investigate the first versions of DENUVO (eq VMProtect 2-3), when there were no lifters and other modern devirtualisation tools. DENUVO_Profiler is a subsequent development of the SecuROM_Profiler utility - the simplest tool for visualising the operation of a virtual machine and effectively controlling the data it uses in the byte-code tape (p-code). DENUVO_Profiler also hunts for Electronic Arts (Origin) licence containers on the current user's machine and can extract their contents, with including the GameToken. # See also: 80_PA SecuROM keygen -
