Abstract: A method involves determining a threshold error rate that will result on data stored on a magnetic disk surface of a disk drive being unrecoverable. The method also involves determining a seek velocity that will overwrite sufficient portions of the data such the data will exhibit at least the threshold error rate. The disk drive performs at least one traversal of the magnetic disk surface with a head of the disk drive that emits an erase field during the at least one traversal at the seek velocity. The at least one traversal sanitizes the data.

Abstract: A method for generating an update package of software. Each installation package of the software includes multiple installation subpackages, and each installation subpackage includes multiple installation files. The method includes: obtaining first feature information and second feature information, the first feature information corresponds to the first installation subpackage, the second feature information corresponds to the second installation subpackage, the first installation subpackage is an installation subpackage in an installation package corresponding to a upgraded software version of the software, and the second installation subpackage is an installation subpackage corresponding to the first installation subpackage in an installation package corresponding to software version of the software before software upgrading; generating the update package for the software according to the first installation subpackage when the first feature information is different from the second feature information.

Abstract: A method for operating a second system application in a first system is provided The method includes: creating an operating environment of the second system application through a loader on a target terminal; generating an application function component of the second system application in the loader; compiling script files of the second system application into dynamic library files by utilizing the compiling environment supported by the target terminal, and encapsulating the dynamic library files into an application package; installing the application package through the loader, and operating the dynamic library files in the application package under the operating environment. According to the aforesaid method, target terminal can directly respond to a system instruction generated during execution of the compiled dynamic library files without the need of parsing and converting the system instruction, thus, a cross-platform operation efficiency of the application program can be improved.
