MINIX 3 is a free, open-source, operating system designed to be highly reliable, flexible, and secure. It is based on a tiny microkernel running in kernel mode with the rest of the operating system running as a collection of isolated, protected, processes in user mode.
The Genode operating-system framework provides a uniform API for applications on top of 8 existing microkernels/hypervisors: Linux, L4ka::Pistachio, L4/Fiasco, OKL4, NOVA, Fiasco.OC, Codezero, and a custom kernel for ARM SoCs. For developers, the framework provides an easy way to target multiple different kernels instead of tying the development to a particular kernel technology.
Unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels. Load balancing is done entirely by the operating system kernel. Requests never pile up behind a busy worker process. Does not care if your application is thread-safe or not, workers all run within their own isolated address space and only serve one client at a time for maximum robustness.
Subversion is an open source version control system. Founded in 2000 by CollabNet, Inc., the Subversion project and software have seen incredible success over the past decade. The open source community has used Subversion widely: for example in projects such as Apache Software Foundation, Free Pascal, FreeBSD, GCC, Django, Ruby, Mono, SourceForge, ExtJS, Tigris.org, PHP and MediaWiki. Google Code also provides Subversion hosting for their open source projects.
Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 29000 packages, precompiled software bundled up in a nice format for easy installation on your machine.
The Xen hypervisor is a layer of software running directly on computer hardware replacing the operating system thereby allowing the computer hardware to run multiple guest operating systems concurrently. It suppors x86, x86-64, Itanium, Power PC, and ARM processors allow the Xen hypervisor to run on a wide variety of computing devices.
Tizen is an open source, standards-based software platform for multiple device categories, including smartphones, tablets, netbooks, in-vehicle infotainment devices, smart TVs, and more. Tizen offers an innovative operating system, applications, and a user experience that consumers can take from device to device.
ttyrpld is a multi-OS kernel-level TTY keylogger and screenlogger with (a)synchronous replay support. It runs on Linux, Solaris, FreeBSD, NetBSD and OpenBSD.
Quantix is a microkernel operating system distribution based on the Mach kernel. Quantix uses the X windowing environment for a user interface.
VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. VirtualBox runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems. So, for example, you can run Windows and Linux on your Mac. VirtualBox is a so-called hosted hypervisor. It requires an existing operating system to be installed. It can thus run alongside existing applications on that host.
