Abstract: Methods, systems, and products secure access to a file system. A directory is established in a hierarchical file structure having access permission defined by a first owner. A subdirectory is established in the directory. A sub-level subdirectory is established in the subdirectory having access permissions defined by a second owner. The subdirectory is publically accessible to anyone satisfying the access permission defined by the first owner, such that a change directory system call is executed for a user in the subdirectory, even though the user has not authenticated the access permission defined by the second owner.

Abstract: A method of managing a plurality of computing resources including obtaining a first load threshold and a second load threshold, obtaining a first load value and a second load value, comparing the first load threshold and the second load threshold with the first load value and the second load value, and changing an operating mode of a resource of the plurality of computing resources when both the first load threshold and the second load threshold are between the first load value and the second load value.
