A first and a second computing environments are generated on a computer system based on a state of a logical storage unit of the computer system. The computing environments are associated with pieces of storage space located outside the logical storage unit. A write operation addressing the logical storage unit in one computing environment is directed to a piece of storage space associated with that computing environment.

Multiple computing environments on a computer system

Analysis of system information includes retrieving selected snapshots comprising the system information to be analyzed. Further, one or more operations can be performed on the system information to extract resultant information. The resultant information can be provided over a graphical user interface to a user.

Analysis of system information

Examples are directed to detect screen contact using total internal reflection. One example involves detecting contact on a screen, the screen comprising total internal reflection of light; and determining, via at least one processor, a location of the contact on the screen based on a disturbance of the total internal reflection, the disturbance caused by the detected contact.
