Methods and systems for providing an emergency incident response are described. Data is received from a plurality of heterogeneous data feeds each having a native format and including one or more publically-available data feeds. Event data is extracted from the received data, the event data representing one or more events from one or more of the plurality of heterogeneous data feeds, and the event data is translated from the native format into a standardized analysis format. Further, an existence and a priority level of at least one emergency incident contemporaneous with the event data and based at least in part on the event data is determined, the priority level being selected from among a plurality of predefined priority levels, and a graphical user interface including a message describing the at least one determined emergency incident is displayed.

Methods and systems for determining public events are described. Data is received from a plurality of heterogeneous data feeds each having a native format. Event data objects are generated based on the received data, the event data objects each including at least a human readable message, an event time, and an event location. The human readable message of each of the event data objects is parsed into keywords, and the event data objects are grouped into one or more public events based on the keywords, time, location, and a sentiment based on the keywords. The public events are filtered based on a filter score, and the event data objects are clustered based on sentiment, location, and time. A density of the clustered event data objects is determined, and the validity of the public events is determined by a comparison of the density to a predetermined density threshold.

Methods and systems for periodically generating and managing passwords for one or more websites of users are disclosed. The users are provided with the ability to automatically replace their old passwords with new passwords for their one or more website accounts. The users can set a pre-determined frequency at which their passwords are to be updated and replaced with new passwords. The users can further define additional one or more rules based on which their passwords are updated. The methods and systems are further configured to auto log into user's website accounts with the updated passwords.

Methods and systems for managing reset of a physical function of an I/O device in a computing system are disclosed, where the physical function is included in a single-root PCI manager. One method includes maintaining a count of active virtual functions associated with the physical function included in the single-root PCI manager, and, upon determining that no active virtual functions are associated with the physical function, allowing the physical function to be reset within the single-root PCI manager. The method further includes while resetting the physical function, persisting a configuration memory space associated with the physical function, and associating the persisted configuration memory space with the physical function after the physical function is reset.

Methods and systems for allocating, one or more virtual functions of a plurality of virtual functions associated with physical functions of I/O interface devices of a computing device are described. One method includes managing one or more physical functions of an I/O interface device within an interconnect partition of a multi-partition virtualization system implemented at least in part on the computing device. The method further includes, during a boot process of a second partition on the computing device, parsing a file to determine an assignment of one or more virtual functions to the second partition and associate each of the one or more virtual functions to corresponding physical functions.

Methods and systems for containing data errors in a computing system are disclosed. One method includes receiving data from an endpoint at the communication interface in response to a data request. The method also includes detecting an error in the data. The method further includes ignoring subsequent data received from the endpoint.

Uncorrectable data error containment systems and methods

Methods and apparatus for allocating access to a buffer of a host device to buffer data transferred between a controller of the host device and one or more remote devices are disclosed. The host device is configured to couple to each of the one or more remote devices through one or more corresponding dedicated lanes. Buffer access is allocated by determining, for each of one or more remote devices coupled to the host device, a number of dedicated lanes between the host device and each of the one or more remote devices and allocating access to the buffer of the host device for each of the one or more remote devices responsive to the determined number of dedicated lanes.

Variable compensation for part to part skew of components in a substrate-mounted circuit is described. The variability may be provided through a computer software program acting on a programmable delay buffer such that compensation for a skewed signal may be continuously checked against a reference signal or through other methods. The skewed signal may be delayed until the signal matches, within a predetermined margin of error, the reference.

Apparatus is provided for transferring user defined data from a parallel storage medium to a serial link driver in an I/O channel subsystem of a processor or I/O device controller. The serial link driver transmits a frame of user defined data over a serial data transfer medium. A data buffer receives and stores user defined data from the parallel storage medium. A control data facility that is distinct from the data buffer forms and transmits control data from the sender of the frame to the recipient of the frame via a path that does not include the data buffer. The control data facility includes respectively different dedicated logic for asynchronously generating each of the following: special character sequences, frame delimiters, headers, and cyclic redundancy checksums. A switching facility receives the user defined data from the data buffer. The switching facility also receives control data from the control data facility. The switching facility provides either the user defined data or the control data to the serial link driver. A data path control mechanism signals the switching facility to alternately provide the control data and the user defined data to the serial link driver, thereby forming frames.

Serial I/O channel having dependent and synchronous sources of control

An Input/Output (I/O) subsystem is provided for transferring frames containing frame control data from a serial data transfer medium to a parallel storage medium. The subsystem includes independent components for processing different portions of the received character stream. The subsystem includes a sequence recognition mechanism for receiving and identifying any of a plurality of digital data bit sequences. The sequences represent channel status information from the data transfer medium. The sequence recognition mechanism provides an interrupt signal derived from the sequences. A frame recognition mechanism responds to the interrupt signal. The frame recognition mechanism receives and identifies a start-of-frame delimiter or an end-of-frame delimiter from the data transfer medium. The frame recognition mechanism provides a frame status signal. A frame receiving mechanism responds to the frame status signal. The frame receiving mechanism receives and identifies a frame header from the data transfer medium. The frame receiving mechanism also verifies link and device level I/O protocol compliance asynchronously while any user defined data included in the frame are being received. The frame receiving mechanism also stores the user defined data in the parallel storage medium concurrently with the verification, if any user defined data are included.

Apparatus is provided for use in an Input/Output (I/O) subsystem. The I/O subsystem is coupled to a serial data transfer medium that transmits data from a sender to a recipient. The I/O subsystem processes a frame comprising user defined data and frame control data. The frame is received over the serial data transfer medium. The apparatus includes a mechanism for receiving and validating the frame from the serial data transfer medium. The receiving mechanism transmits the user defined data to a first-in, first-out (FIFO) buffer. A mechanism is provided for forming a block header. The block header comprises control data that are used by the recipient of the user defined data. The block header forming mechanism is distinct from the FIFO buffer. A switching mechanism is coupled to receive the block header and a subset of the user defined data. The recipient has a parallel storage medium. The switching mechanism transmits either the block header or the subset of the user defined data to the parallel storage medium. A control mechanism provides signals to configure the switching mechanism to alternately transmit the block header and the subset of the user defined data to the parallel storage medium. By alternating the block header and data, a data block is formed having a size that equals the native sector size of the recipient.
