Abstract: The present disclosure provides a packet modification method and apparatus, a computer device, and a storage medium. The method includes: dividing a field to be modified that is related to packet encapsulation information into M containers; performing instruction extraction on a very long instruction word executing a modification command, to obtain N groups of initial instructions, where 2?N?M; processing the N groups of initial instructions to obtain N groups of source operands and N groups of modification field configuration information; determining, according to the N groups of modification field configuration information, N containers matched with the N groups of source operands, respectively; and modifying, according to the N groups of source operands, the N matched containers, respectively.

Abstract: The present disclosure provides a writing method, including: writing writing-table data into a corresponding main storage module; performing a calculation on writing-table data in each target main storage module by using a first predetermined algorithm to obtain an auxiliary value, for any target main storage module, the first predetermined algorithm being used for performing a calculation on writing-table data stored in the target main storage module and corresponding writing-table data stored in at least one main storage module other than the target main storage module, an inverse operation of the first predetermined algorithm being used for performing a calculation on any auxiliary value to obtain writing-table data participating in the calculation of the auxiliary value; and storing the auxiliary value into a corresponding auxiliary storage module. The present disclosure further provides a reading method, a computer readable storage medium, a processor chip and an electronic device.

Abstract: An apparatus and method for generating an application container are provided. The method includes selecting a target application from among a plurality of applications included in an electronic device, acquiring a policy file corresponding to the target application, determining whether the policy file includes a category of the target application, and executing the application container which includes the target application.

Abstract: An apparatus and method to authorize Application Programming Interface (API) or method level access in system and application services are provided. The method includes receiving a request for access to a service from another service or an application via an interface accessible by the other service or the application, and determining whether to authorize the request based at least in part on a specified policy.

Abstract: A matrix assisted laser desorption and ionization system is provided. The system includes a mass spectrometer for analyzing at least one sample. The mass spectrometer includes a sample receiving chamber for receiving a sample under a vacuum. A UV laser is provided for producing a UV beam along a first beam path that does not intersect with the sample. A beam expander is provided in optical communication with the UV laser beam to expand the diameter of the beam. A focusing system is provided in optical communication with the beam expander to focus the laser beam propagating from the beam expander to a predetermined minimum spot size. The focusing system is located along the path of the beam propagating from the beam expander so that the beam strikes the approximate optical center of the focusing system. A high reflecting mirror is provided in optical communication with the focused beam propagating from the focusing system to direct the focused beam to strike the sample at a preselected strike point.
