A method for estimating movement of a mobile device includes: obtaining images from a camera communicatively coupled to a processor of the mobile device; identifying a stationary light source using at least one image of the images; calculating a displacement of the stationary light source based on a first location of the stationary light source in a first image of the images and a second location of the stationary light source in a second image of the images, the first image and the second image being captured at different times; and estimating movement of the mobile device based on the displacement.

A mechanism is provided for increasing the efficiency of block-level processes. Responsive to detecting an I/O write to a storage volume, a determination is made as to whether the I/O write matches one or more suspicious I/O reads in a plurality of suspicious I/O reads previously recorded in a memory. Responsive to the I/O write matching one or more suspicious I/O reads in the plurality of suspicious I/O reads, an identification is made that there is a data relocation associated with the sector associated with the I/O write. A data relocation application is informed of the data relocation of the sector associated with the one or more suspicious I/O reads associated with the sector indicated by the I/O write. Each sector associated with the one or more suspicious I/O reads is then released in a file system for reuse.

Provided are a computer program product, method, and system for backing-up a volume of blocks of data in a storage system. Selection is received of selected files in a volume indicating files to backup. A determination is made from the selected files blocks in the files to backup. A volume backup map is generated indicating the determined blocks to backup. A file list of the selected files to backup and the volume backup map are stored in backup information for the backup. The blocks indicated to backup in the volume backup map are copied to a backup file on a block-by-block basis.

Selecting files to backup in a block level backup

A method for computing includes running a desktop sharing program on a local computer so as to permit a remote user to view, on a remote computer, which is connected to communicate with the local computer via a network, an image of an entire area of a display screen of the local computer and to operate the local computer by remote input via the remote computer. A local window is defined within the display screen of the local computer for running an application under control of a local user. Local inputs made via a local input device of the local computer by the local user are intercepted so that the local inputs do not interfere with operation of the local computer by the remote user. The intercepted inputs are directed to the local window so as to permit the local user to interact with the application independently of the operation of the local computer by the remote user.

Simultaneous remote and local control of computer desktop

Methods, devices, and systems for detecting return-oriented programming (ROP) exploits are disclosed. A system includes a processor, a main memory, and a cache memory. A cache monitor develops an instruction loading profile by monitoring accesses to cached instructions found in the cache memory and misses to instructions not currently in the cache memory. A remedial action unit terminates execution of one or more of the valid code sequences if the instruction loading profile is indicative of execution of an ROP exploit involving one or more valid code sequences. The instruction loading profile may be a hit/miss ratio derived from monitoring cache hits relative to cache misses. The ROP exploits may include code snippets that each include an executable instruction and a return instruction from valid code sequences.
