Abstract: Data symbols in an input signal are detected with a slicer of a DFE of a transceiver device. An output of a feedback filter of the DFE is generated, during a particular clock cycle, based on a first set of one or more data symbols detected during first one or more previous clock cycles and a second set of one or more data symbols detected during second one or more previous clock cycles. The second set is separated from the first set by a third set of one or more data symbols detected during third one or more clock cycles that occur after the first one or more clock cycles and before the second one or more clock cycles, where the output is generated without use of the third set of symbols. The output is subtracted from the input signal to generate an equalized input to the slicer.

Abstract: Available capacity of resources hosted in different networks may be evaluated to select resources for the performance of a query. A query may be received via an interface for one network. The available capacity of the one network and other networks may be evaluated to select resources hosted in another network to perform the query instead of the resources in the one network. The query may then be routed to the resources in the other network and result of the query performed at the resources in the other network provided.

Abstract: Queries may be received and executed by a managed query service. A query directed to data sets that are separately stored in a remote data store may be received. Computing resources to execute the query may be provisioned from a pool of computing resources that are configured to execute queries. The query may be routed to the provisioned computing resources to execute the query. Results may be obtained from the computing resource and provided to a submitter of the query.

Abstract: Techniques and systems for migrating links in documents are described. For example, during a migration process, a first document may be selected to be migrated from a source document database. A determination may be made that the first document includes a link to a second document. The first document may be migrated to a target document database. The second document may be selected to be migrated from the source document database. The second document may be migrated to the target document database. The link in the first document may be finalized to include an address of the second document in the target document database.

Abstract: An Ethernet physical layer (PHY) transceiver includes a transmitter and a receiver. The transmitter is configured to precode a first data stream by summing two or more mutually-delayed replicas of the first data stream, and to transmit the precoded first data stream over a full-duplex wired channel to a peer Ethernet PHY transceiver. The receiver is configured to receive a second data stream from the peer Ethernet PHY transceiver over the full-duplex wired channel, and to decode the received second data stream while the transmitter concurrently is transmitting the precoded first data stream.

Abstract: Query execution status may be tracked to selectively route queries to resources for execution. The completion of queries executing at computing resources obtained from a pool of computing resources configured to execute queries may be detected. Instead of returning the computing resources to the pool, the computing resources may be identified as available in resource management data. When another query is received, the resource management data may be evaluated to select an available computing resource. The query may then be routed to the selected computing resource for execution.

Abstract: Embodiments described herein provide a method for waking a first node in a low power mode. A network comprises at least the first node and a second node in an awake mode where the first and second nodes have respective transceivers coupled via substantially fixed communication pathways. The transceiver of the second node obtains a training signal designed to be transmitted at a pre-defined symbol rate and transmits the training signal at a symbol rate lower than the pre-defined symbol rate to the physical layer of the first node for a predetermined duration of time. The second node, in response to receiving the training signal transitions from the low power mode to an awake state.

Abstract: The configuration of computing resources for executing queries may be selected. A comparison of the configuration of computing resources that executed previous queries may be made to select the configuration of computing resources for a received query. A historical query execution model maybe applied, in some embodiments, to determine a resource configuration for computing resources to execute a query. The computing resources may be selected from available computing resources according to the determined resource configuration.

Abstract: Methods and apparatus for providing consistent data storage in distributed computing systems. A consistent distributed computing file system (consistent DCFS) may be backed by an object storage service that only guarantees eventual consistency, and may leverage a data storage service (e.g., a database service) to store and maintain a file system/directory structure (a consistent DCFS directory) for the consistent DCFS that may be accessed by compute nodes for file/directory information relevant to the data objects in the consistent DCFS, rather than relying on the information maintained by the object storage service. The compute nodes may reference the consistent DCFS directory to, for example, store and retrieve strongly consistent metadata referencing data objects in the consistent DCFS. The compute nodes may, for example, retrieve metadata from consistent DCFS directory to determine whether the object storage service is presenting all of the data that it is supposed to have.

Abstract: A method for communication, including, in a Physical Layer (PHY) transceiver, selecting a transmission bitrate from a plurality of transmission bitrates, for transmitting over a media interface bits received from an external device. The received bits are processed by generating, using a framing and encoding scheme that depends on at least the selected transmission bitrate, frames having a common frame length among the framing and encoding schemes. The frames are encoded to produce code words of a predefined Forward Error Correction Code (FEC) code, using a single FEC encoder that accepts a number of bits for encoding equal to the frame length. Sub-units of the code words are mapped into symbols using one of at least two mapping schemes that employ different voltage amplitude levels to define a transmission symbol, the mapping scheme being selected according to the selected transmission bitrate. The symbols are transmitted over the media interface.

Abstract: An air pre-cleaning assembly includes a motor that has a stator and a rotor shaft assembly configured with a fan. The motor is disposed at the upstream of the fan, and rotation of the fan is configured to yield an air flow passing through the motor. A cyclone separating element on the upstream path of the air flow on the motor includes an air inlet, a separating chamber, a dust collecting chamber, and an air outlet. The separating chamber is communicated with the air inlet. The dust collecting chamber is communicated with the separating chamber and located at its outer periphery. The air outlet is communicated with the separating chamber and located at its inner periphery. The motor is located at the downstream of the air outlet. The cyclone separating element allows clean air filtered by cyclone filtering to pass through the motor via the air outlet.
