Abstract: One or more techniques and/or computing devices are provided for inline deduplication. For example, a checksum hash table and/or a block number hash table may be maintained within memory (e.g., a storage controller may maintain the hash tables in-core). The checksum hash table may be utilized for inline deduplication to identify potential donor blocks that may comprise the same data as an incoming storage operation. Data within an in-core buffer cache is eligible as potential donor blocks so that inline deduplication may be performed using data from the in-core buffer cache, which may mitigate disk access to underlying storage for which the in-core buffer cache is used for caching. The block number hash table may be used for updating or removing entries from the hash tables, such as for blocks that are no longer eligible as potential donor blocks (e.g., deleted blocks, blocks evicted from the in-core buffer cache, etc.).

Abstract: Techniques are provided for asynchronous semi-inline deduplication. A multi-tiered storage arrangement comprises a first storage tier, a second storage tier, etc. An in-memory change log of data recently written to the first storage tier is evaluate to identify a fingerprint of a data block recently written to the first storage tier. A donor data store, comprising fingerprints of data blocks already stored within the first storage tier, is queried using the fingerprint. If the fingerprint is found, then deduplication is performed for the data block to create deduplicated data based upon a potential donor data block within the first storage tier. The deduplicated data is moved from the first storage tier to the second storage tier, such as in response to a determination that the deduplicated data has not been recently accessed. The deduplication is performed before cold data is moved from first storage tier to second storage tier.

Abstract: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for ranging procedures performed using antenna switching. In one aspect, a device initiating a ranging procedure may transmit a ranging request, which may include antenna switching capabilities of the initiating device, a request for antenna switching by a responding device during the ranging procedure, or both. Ranging signaling may be communicated between the initiating device and the responding device using different transmit antennas, receive antennas, or both. In some implementations, ranging messages transmitted by the responding device may include transmit antenna indices used for transmission of different ranging messages, and receive antenna indices used for reception of different ranging response messages.

Abstract: A method for real-time analysis of results from a load test performed on a target website includes calculating first-level aggregated test results within each of a plurality of load server instances that generate a load on the target website. The first-level aggregated test results are calculated from data points received by each of the load server instances from the target website. The first-level aggregated test results include a sum of the data points, a count of the number of the data points, a sum of squares of the data points, and an average of the data points. A standard deviation result (STDEV) is calculated and chart is generated on a display via a graphical user interface. The chart provides a visual representation of a performance metric for the load test based on the standard deviation result.

Abstract: A method and apparatus for re-associating a station (STA) to an access point (AP). The STA sends a re-association request to the AP to initiate a re-association process with the AP. The re-association request indicates that a handshake operation is to be bypassed during the re-association process. The STA receives a re-association response from the AP in response to the re-association request and, upon receiving the re-association response, enables data communications with the AP using a set of preexisting cryptographic keys. For example, the set of preexisting cryptographic keys may be negotiated with the AP during at least one of a prior association process or a prior re-association process.

Abstract: A method for real-time capture of analytics from real users of a native mobile application (app) includes storing a custom metric/timer definition for a native mobile application (app) in a configuration file on a server. The custom metric/timer definition includes one or more identifiers of an element or object of the native mobile app selected by touch gesture input via a user interface on a mobile device running the native mobile app in a special mode. The configuration file is downloaded from the server to real users running the native mobile app on associated mobile devices. Immediately thereafter, one or more collector servers receive data beaconed in real-time from the associated mobile devices of the real users. The beaconed data includes custom metric/timer data obtained from the custom metric/timer definition.

Abstract: In a wireless network, a first wireless device may send a first frame instructing a second wireless device to suspend a block acknowledgement session while the first wireless device is facilitating a Bluetooth operation. When the Bluetooth operation is complete, the first wireless device may send a second frame instructing the second wireless device to resume the block acknowledgement session.

Abstract: A technique for data de-duplication is applied to suspend and resume operations for virtual machines (VMs) to reduce the time needed to suspend or resume a virtual machine and store the suspended VMs in a space-efficient and time-efficient manner. A VM's state is serialized and written to disk in the form of key values that are used to retrieve data from a key-data map. The key-data map stores unique data blocks for suspended VM images. The key-data map can be stored in a solid-state drive to further reduce latency and access time.

Abstract: Disclosed is a three layer process for making contact points to a high transition temperature superconductor (HTSC), particularly to (Bi,Pb)2 Sr2 Ca2 CU3019+x with and without silver in the superconductor. The contact structure is a three layer configuration with a perforated silver foil (3) sandwiched between two metal spray gun deposited silver layers (2,5) and subsequent heat treatment in air. The contact has been made on tubes and rods (1). The silver contacts are capable of carrying a continuous current of 200 Amps without adding any substantial heat load to the cryogen used to cool the HTSC. The contact resistance at 4.2 K is in the range of 1.5×10 (hoch?8) to 8.5? 10 (hoch?8) OHM in zero applied filed.
