User account creation involving a mobile device
Mobile devices may often communicate with network (“cloud”) services that require an account. Because it may be undesirable to require user interaction when creating an account, it may be desirable to create an account associating a mobile device to a network service without requiring a user to explicitly enter authentication information, such as a username and password. In an embodiment, data corresponding to a mobile device is obtained to generate authentication information which is then sent to messaging address of a user. In another embodiment, in response to an event, a mobile device obtains an identifier for a user, sends the identifier to a server, where the server transmits one set of authentication information to a messaging address associated with the user and another set of authentication information to the device. |

Malware removal without virus pattern
Antivirus software detects malware on a computer and the landing time of the malware is determined; a time window around the landing time is determined. Optionally requiring the landing time of the malware to be before the installation time of the antivirus software eliminates false positives. Any files of the computer systems that have a creation time within the time window are suspect. If the prevalence value and the maturity value of the suspect file are below respective thresholds then it is concluded that the file is malware and it is deleted. No virus signature or virus pattern that matches the deleted file need be relied upon or used. The detected malware may be the original mother file or a dropped file. An online prevalence and maturity database is used. The launching time of the malware may be used instead of the landing time. |

System and method for run-time attack prevention
Preventing attacks on a computer at run-time. Content that is configured to access at least one function of a computer is received by the computer. Protections corresponding to the function are added to the content, wherein the protections override the function. The content and the protections are then transmitted to the computer. The function may expose a vulnerability of the computer, and arguments passed to the function may exploit that vulnerability. The protections are executed when the content is executed, and determine whether the arguments the content passed into the function represent a threat. In response to determining that the arguments represent a threat, execution of the content is terminated without executing the function. |

Low-density parity-check decoder disparity preprocessing
Described embodiments provide a media controller that performs error correction on data read from a solid-state media.

Extending flash memory data retension via rewrite refresh
Providing for extended data retention of flash memory devices by program state rewrite is disclosed herein. By way of example, a memory cell or group of memory cells can be evaluated to determine a program state of the cell(s). If the cell(s) is in a program state, as opposed to a natural or non-programmed state, a charge level, voltage level and/or the like can be rewritten to a default level associated with the program state, without erasing the cell(s) first. Accordingly, conventional mechanisms for refreshing cell program state that require rewriting and erasing, typically degrading storage capacity of the memory cell, can be avoided. As a result, data stored in flash memory can be refreshed in a manner that mitigates loss of memory integrity, providing substantial benefits over conventional mechanisms that can degrade memory integrity at a relatively high rate. |

Adaptive power conservation in storage clusters
Each node and volume in a storage cluster makes a decision whether to reduce power consumption based on lack of requests from client applications and nodes over a time period. Node configuration parameters determine how long to wait until idling a node or volume, and how long to wait while idle before performing integrity checks. A bid value is calculated by each node and reflects how much it will cost for that node to write a file, read a file, or keep a copy. A node with the lowest bid wins, and nodes that are idle have a premium added to each bid to ensure that idle nodes are kept idle. In an archive mode, writes bids are reversed, nodes with less capacity submit lower bids, fuller nodes fill up faster and are then idled, while empty or near empty nodes may remain idle before winning a write bid. |

Mechanism for enabling a network address to be shared by multiple labeled containers
A mechanism is disclosed for enabling a network address to be shared by multiple containers.

Low complexity auditory event boundary detection
An auditory event boundary detector employs down-sampling of the input digital audio signal without an anti-aliasing filter, resulting in a narrower bandwidth intermediate signal with aliasing. Spectral changes of that intermediate signal, indicating event boundaries, may be detected using an adaptive filter to track a linear predictive model of the samples of the intermediate signal. Changes in the magnitude or power of the filter error correspond to changes in the spectrum of the input audio signal. The adaptive filter converges at a rate consistent with the duration of auditory events, so filter error magnitude or power changes indicate event boundaries. The detector is much less complex than methods employing time-to-frequency transforms for the full bandwidth of the audio signal. |
