Abstract: A method for producing lumber from a tree trunk, where a machining surface is produced on the trunk by removing a slab region, and where, during a feed movement in a feed direction, the trunk moves toward at least two milling tools, which are each feedable along an infeed axis, whereby two waney regions adjacent to the machining surface are milled out and at least one side product board is profiled, and the side product board is separated from the trunk by a saw cut. During feeding and before profiling the side product board, the trunk is brought from a transport to a machining position by moving the trunk around and/or along an adjustment axis, which runs orthogonally to the feed direction, and, as a result, at least one leading region of the trunk is shifted transversely to the feed direction in the direction of at least one milling tool.

Abstract: The subject matter herein provides an automated system and method for software patch management that ranks patches at least in part according to a score indicative of a complexity (e.g., cost) of remediating a vulnerability. This score is sometimes referred to herein as a vulnerability remediation complexity (VRC) score. A VRC score provides an objective measure by which an organization can determine which patches are most likely to be successfully applied, thus enabling implementation of a patching strategy that preferentially applies most critical, but less impact (in terms of remediation cost) patches first to remediate as must risk as possible as quickly as possible. Thus, for example, the approach herein enables the patching to focus on vulnerabilities of highest severity and small remediation cost over those, for example, representing lower severity and higher remediation cost.
