Power Transmission Engineer Lionel Barthold Explains how 3 phase, 6 phase, and 12 phase power works, advantages, disavantages, and hopes for the future. Rotating phases, form an anisotropic tube. He worked on experimental 6 and 12 phase power lines at his company Power Technologies, Inc. before it was sold to Siemens after a long successful career. The experimental polyphase lines were located in Malta, New York, not far from company headquarters in Schenectady.

What is MINIX 3?MINIX 3 is a free open-source operating system that can be used for studying operating systems, as a base for research projects, or for commercial (embedded) systems where microkernel systems dominate the market. Much of the focus on the project is on achieving high reliability through fault tolerance and self-healing techniques.MINIX is based on a small (about 12K lines of code) microkernel that runs in kernel mode. The rest of the operating system runs as a collection of server processes, each one protected by the hardware MMU. These processes include the virtual file system, one or more actual file systems, the memory manager, the process manager, the reincarnation server, and the device drivers, each one running as a separate user-mode process.One consequence of this design is that failures of the system due to bugs or attacks are isolated. For example, a failure or takeover of the audio driver due to a bug or exploit can lead to strange sounds but cannot lead to a full takeover of the operating system. Similarly, crashes of a system component can in many cases be automatically and transparently recovered without human intervention. Few, if any, other operating systems are as self-healing as MINIX 3.

QEMU is a generic and open source machine emulator and virtualizer.When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performance.When used as a virtualizer, QEMU achieves near native performance by executing the guest code directly on the host CPU. QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, server and embedded PowerPC, 64-bit POWER, S390, 32-bit and 64-bit ARM, and MIPS guests.QEMU is a member of Software Freedom Conservancy.QEMU releases can be downloaded here: http://www.qemu.org/download/
