摘要： Methods, media, and systems for detecting anomalous program executions are provided. In some embodiments, methods for detecting anomalous program executions are provided, comprising: executing at least a part of a program in an emulator; comparing a function call made in the emulator to a model of function calls for the at least a part of the program; and identifying the function call as anomalous based on the comparison. In some embodiments, methods for detecting anomalous program executions are provided, comprising: modifying a program to include indicators of program-level function calls being made during execution of the program; comparing at least one of the indicators of program-level function calls made in the emulator to a model of function calls for the at least a part of the program; and identifying a function call corresponding to the at least one of the indicators as anomalous based on the comparison.

摘要： A software device to perform math calculations upon numerical or data expressions entries, and capable of coordinating multiple data entries, displays, and storage operations. The package is consisted of dual entry inputs, a single result display, single arithmetic expression display for each entry, and a data spreadsheet matrix which is constantly synchronized with data entries and result contents. The data/arithmetic inputs are entered via the software device control buttons, computer keyboard, software device memory buttons, saved user prior transaction files, the software device entry/result history buttons, or a cut and paste process within the various package displays or external software tools such as Microsoft Office Word and Excel. The software device provides error checking schemes for any type of the above mentioned entry methods in combination with its operation merit monitoring schemes, FIGS. 1 through 21.

摘要： Techniques are provided for redundant execution by a better processor for intensive dynamic profiling after initial execution by a constrained processor. In an embodiment, a system of computer(s) receives a request to profile particular runtime aspects of an original binary executable. Based on the particular runtime aspects and without accessing source logic, the system statically rewrites the original binary executable into a rewritten binary executable that invokes telemetry instrumentation that makes observations of the particular runtime aspects and emits traces of those observations. A first processing core having low power (capacity) performs a first execution of the rewritten binary executable to make first observations and emit first traces of the first observations. Afterwards, a second processing core performs a second (redundant) execution of the original binary executable based on the first traces. The second execution generates a detailed dynamic performance profile based on the second execution.

摘要： A method is provided for operating a memory device. The method includes counting, from among memory cells, a number of first off-cells with respect to a first reading voltage and a number of second off-cells with respect to a second reading voltage, comparing the number of first off-cells and the number of second off-cells, and determining, based on a result of the comparing, whether a programming error exists in a storage region in which the memory cells are included.

摘要： Output is obtained from a remote computer function on a first set of arguments. Responsive to determining that the output exhibits an error, a fixer routine, other than a retry, is applied to the arguments to produce new arguments. Output is obtained from the remote computer function on the new arguments. In a case where the output from the remote computer function on the new arguments is acceptable, the output from the remote computer function on the new arguments is used as a corresponding output from the remote computer function on the first set of arguments. These steps can advantageously be carried out without modifying program code of the remote computer function and without access to the program code of the remote computer function; for example, by a wrapper which black-box wraps the remote computer function.

摘要： Systems and methods for automatically generating failure signatures in a computer system for performing computer system fault diagnosis are provided. The method includes receiving log data, converting each log in the log data into a collection of log pattern sequences including one or more log pattern sequences corresponding to one or more respective failure categories associated with the computer system, generating a collection of seed patterns by computing a global set of patterns from the collection of log pattern sequences, and extracting the collection of seed patterns from the global set of patterns, generating a log pattern grammar representation for each of the one or more log pattern sequences, generating a failure signature for each of the one or more failure categories based on the log pattern grammar representation and the collection of seed patterns, and employing the failure signatures to perform computer system fault diagnosis on new log data.
