W^X
W^X ("Write XOR Execute"; spoken as W xor X) is the name of a security feature present in the OpenBSD operating system. It is a memory protection policy whereby every page in a process' address space is either writable or executable, but not both simultaneously. The name comes from the XOR Boolean operator which outputs 'true' only when either one or the other operand is true, but not both. W^X does not prevent these permissions from being requested by applications, write and executable permissions simply are not used as a matter of policy. The OpenBSD base system has been modified to comply with it. This alleviates some buffer overflow attacks, including the most common stack-based attack: by ensuring that the stack is not executable, arbitrary code injected into it will not execute but instead cause the program to terminate. W^X first appeared in OpenBSD 3.3, released May 2003. Similar features are available for other operating systems, including the PaX and Exec Shield patches for Linux, and NetBSD 4+'s implementation of PaX.
Wendelstein 7-X
The Wendelstein 7-X (W7-X) reactor is an experimental stellarator (nuclear fusion reactor) built in Greifswald, Germany, by the Max Planck Institute of Plasma Physics (IPP), and completed in October 2015. It is a further development of Wendelstein 7-AS. The purpose of Wendelstein 7-X is to evaluate the main components of a future fusion reactor built using stellarator technology, even if Wendelstein 7-X itself is not an economical fusion power plant.
The Wendelstein 7-X reactor is the largest fusion device created using the stellarator concept which was the brainchild of physicist Lyman Spitzer. It is planned to operate with up to 30 minutes of continuous plasma discharge, demonstrating an essential feature of a future power plant: continuous operation.
The name of the project, referring to the mountain Wendelstein in Bavaria, was decided at the end of the 1950s, referencing the preceding project from Princeton University under the name Project Matterhorn.
The research facility is an independent partner project with the University of Greifswald.
