The connector portion (16) is positioned substantially centrally with respect to each side portion. The connector portion (16) has a length of not more than 20 mm. The side portions ((12), (14)) are fabricated from a material which is both resilient and thermally conductive. The first side portion (12) is substantially flat and the second side portion (14) is configured such that it is provided with two fixed states: a first state in which the first side portion is convex in shape and bends away from the second plate; and a second fixed state in which the first side portion is concave in shape and folds over to cover both the connector portion and the first side portion.

Abstract: By obtaining metadata for transactions submitted by a service to a log-first distributed database of a provider network, a metrics manager may determine database replica performance for those transactions and notify clients of potential performance issues. When an instance of the service submits a write transaction to the log-first distributed database, the transaction may include a host name and a timestamp for the submission of the transaction. At a later point in time, a write applier may obtain the transaction and apply it to a local database replica, along with an additional timestamp for the application of the transaction to the replica. A metrics manager may obtain the transaction timestamps from the replica and calculate a latency metric for the propagation of the transaction from the particular service instance/instance host to the replica. The latency metric may be stored or transmitted to an endpoint (e.g., a client or administrator).

Abstract: A hair styling device (10) comprises first and second arms ((12), (14)), each arm having a handle portion ((18), (20)) coupled to a clamping portion ((22), (24)). The arms are coupled to each other at a first end adjacent the handle portions, allowing the clamping portions to be moveable relative to each other between an open position and a closed position in which a curl forming apparatus may be held between the clamping portions. The clamping portion (22) of the first arm (12) houses a heater element and includes a concave shaped surface heatable by the heater element. The clamping portion (24) of the second arm (14) includes a convex shaped clamping surface. When the clamping portions are in a closed position, the heatable surface of the first arm and the clamping surface of the second arm are spaced apart by a separation distance.

Abstract: Systems and methods for generating dynamic sparse exponential histograms. The system includes a network-based service and a data compression engine to generate a sparse exponential histogram (SEH) representation of a distribution of a plurality of data values of a performance metric of the network-based service. The data compression engine is configured to, map each data value to a bin of an exponential histogram. Responsive to a determination that the mapped bin is not indicated in the SEH representation and that a bin quantity limit would be exceeded by adding the mapped bin, the data compression engine is configured to increase a bin size parameter by a scaling factor to expand data value ranges of the bins, merge bins indicated in the SEH representation according to the expanded data value ranges to reduce the quantity of bins indicated in the SEH representation, and indicate the scaling factor in the SEH representation.

Abstract: A computing resource service receives a request to retrieve data, wherein fulfillment of the request involves retrieval of representations of the data from a number of datastores maintained by the service. The service transmits requests to individual datastores to retrieve the representations of the data. Before all responses to these requests are received, the service evaluates any received responses to determine whether a quorum has been reached with regard to the representations of the data. If so, the service consolidates the representations of the data and provides the consolidated data to fulfill the request.

Abstract: A first value of a first data type is obtained as input. A second value of a second data type is obtained based at least in part on the first value. The second value is determined to match the first value without losing precision. The second value is determined to be greater than a maximum value for a third data type, and less than or equal to a maximum value for a fourth data type. A marker value is stored in a first storage location, the marker value indicating that a second storage location holds a value of the fourth data type. The second value is stored in the second storage location as the fourth data type.

Abstract: A computing resource monitoring service receives a request to store a measurement for a metric associated with a computing resource. The request includes the measurement itself and metadata for the measurement, which specifies attributes of the measurement. Based at least in part on the metadata, the computing resource monitoring service generates a fully-qualified metric identifier and, using the identifier, selects a logical partition for placement of the measurement. From the logical partition, the computing resource monitoring service transmits the measurement to an aggregator sub-system comprising one or more in-memory datastores. The computing resource monitoring service stores the measurement in an in-memory datastore within the aggregator sub-system.

Abstract: A computing resource monitoring service receives a request to retrieve measurement data for a metric. The computing resource monitoring service determines, based at least in part on information included in the request, one or more in-memory datastores where the measurement data is stored. If the information indicates that the computing resource monitoring service is to provide an authoritative subset of the measurement data, the computing resource monitoring service limits the data provided in response to the request to the authoritative subset of the measurement data. Otherwise, if the information does not specify this indication, the computing resource monitoring service will provide the measurement data that is available.

Abstract: A computing resource monitoring service receives a plurality of measurements for a metric associated with an auto-scale group. Each measurement is associated with metadata for the measurement, which specifies attributes for the measurement. The computing resource monitoring service determines, for each measurement and based at least in part on the metadata, a fully qualified metric identifier for the measurement. The service partitions the plurality of measurements into a plurality of logical partitions associated with one or more in-memory datastores. The service transmits the measurements from the plurality of logical partitions to the one or more datastores for storage of the measurements. These measurements are provided to one or more computing resource managers for the auto-scale group to enable automatic scaling of computing resources of the group based at least in part on the measurements.

Abstract: A web server computer system receives a plurality of measurements for a metric from one or more computing resources associated with the web server computer system. Each measurement includes metadata for the measurement, which specifies attributes of the measurement. The web server computer system determines, for each measurement and based at least in part on the metadata, a fully qualified metric identifier for the measurement. The web server computer system uses the fully qualified metric identifier to partition the plurality of measurements into various partitions. Once completed, the web server computer system transmits a request to one or more aggregator sub-systems of a computing resource monitoring service to store the plurality of measurements.

Abstract: A computing resource monitoring service receives a request to store metrics data. The request includes the metrics data and a fully qualified metric identifier generated based at least in part on metadata included in an earlier request to store other metrics data for the same metric. The service uses the fully qualified metric identifier to identify an aggregator datastore for storing the metrics data. Once the service has identified the aggregator datastore, the service accesses the aggregator datastore to store the metrics data such that the metrics data and the other metrics data can be obtained in response to a request to obtain data for the metric, where the request includes the metadata.
