Abstract: Technologies are presented for reducing the network delivery speed of a datacenter deployment within a controlled performance definition while also reducing the overall bandwidth demand on core servers in the datacenter. In some examples, a throttle may be used adjusting (e.g., slowing) data flow that is informed of both network performance and total allowable delay, and a compression/deduplication process. The compression/deduplication process may reduce amounts of stored data by compressing stored data or removing duplicate data and may be a transportable infrastructure process. The compression/deduplication process may also be hardware-assisted with network processors in the datacenter.

Abstract: Technologies are generally described for suppressing discovery of mobile devices in a wireless ubiquitous computing (ubicomp) network, reducing the number of network transmissions by devices in the network and reducing network congestion and prolonging battery life. A mobile device may add supplementary information to introductory beacons transmitted by the device that indicate no response is necessary from other devices participating in the network except for a coordinator of the network. The mobile device may transmit a malformed introductory beacon that will be ignored by other devices in the network except for the coordinator. The coordinator of the wireless network may detect the mobile device moving through the network and transmit a suppression signal to other devices in the network causing the devices to ignore the introductory beacons transmitted by the mobile device.

Abstract: Technologies are provided for shared secret generation between a server and a client using cached data. In some examples, a server may send a number of encrypted secrets to a client that caches a number of data blocks previously provided by the server. Each of the encrypted secrets may be encrypted using a data block that may or may not be cached at the client. The client may then identify the encrypted secrets that correspond to data blocks in its cache and use those data blocks to recover those secrets. The client may then encrypt a message for the server using the recovered secrets. Upon reception of the message, the server may then recover the message using its knowledge of the data blocks cached at the client.

Abstract: Technologies are generally provided for progressive key value store switchover by evaluating a maturity of a migrated data store and allowing piecewise switching of substructure area query servicing from an origin data store to a destination data store. In some examples, abstractions of origin and destination tree structures may be compared to each other in order to generate an evaluation metric at substantially reduced performance evaluation load. The evaluation metric may target performance sampling while assuring a desired performance level with localized query servicing switchover. Piecewise data transfer may also be optionally enabled such that overall storage can be similar to the storage of a single data store copy while reducing an impact on existing data store services.

Abstract: A dynamically alterable cell support may be altered at a large scale to induce mechanical removal of adherent cells in culture without the use of a removal solution. For example, adherent cells may be cultured on an elastic support with one or more textured surface regions and removed by expansion/contraction of the support. Mechanical removal of adherent cells may reduce or minimize damage to cell surface markers, cellular morphology, and/or cellular physiology associated with the detachment and resuspension of cultured adherent cells.

Abstract: Technologies related to mobile device prevention of contactless card attacks are generally described. In some examples, a mobile computing device may monitor for electromagnetic signals at frequencies used for short range communications with contactless cards. Detection of such electromagnetic signals by the mobile computing device may indicate an attack attempt on a proximal contactless card. In response to detection of such electromagnetic signals, the mobile computing device may automatically generate a disruption signal effective to disrupt communications between contactless card readers and any proximal contactless cards, to thereby foil the attack before sensitive contactless card data is stolen.

Abstract: The present technology provides an illustrative apparatus for recycling electric arc furnace (EAF) dust and method of use related to the same. The apparatus has a heat controlling region coupled to a separation volume and includes at least one magnet and a cooling region. The heating controlling region operates at a temperature sufficient to transform at least some of the EAF dust into a mixture of gaseous zinc and one or more additional metals. The magnet separates the iron-rich material from the mixture of gaseous zinc and one or more additional metals and the cooling region condenses the gaseous zinc.

Abstract: Technologies are generally described for a system to establish a secure connection between a wireless device and another device or a recognized service using device network records. According to some examples, the wireless device may send an authentication request to initiate a communication session with another wireless or a recognized service. The authentication request may be encrypted with a first secret, or a hash, synthesized by the device based on the network records associated with the device. The device may be authenticated using the network's copy of the network records. The network may similarly authenticate the identity of the recognized service or other device. The network may synthesize a second secret based on the network records, and may provide the second secret to the recognized service or other device to enable a communication session secured by the second secret.

Abstract: Technologies are generally described for detecting transcoding and adjusting visual content for optimal display on user devices. A content provider may transmit a sample of a visual content to a user device over a service provider network, and may monitor the quality of the sample that the user device receives. The service provider may apply transcoding to the sample during the transmission causing the quality of the sample to be degraded. The content provider may receive a sample as rendered from the user device and may compare the sample as rendered to the visual content to identify a transcoding applied by the service provider network. The content provider may the transcoding to the visual content and may transmit visual content that is transcoded for optimal display over the service provider network to the user device.

Abstract: Technologies are generally described for mitigation of a convergence attack in a network portion that includes multiple nodes interconnected by links in a closed configuration. In some examples, the attack may be detected by a detection module of an attack mitigation system in response to a determination that received average time to live (TTL) values of data packets are substantially decreased over the multiple nodes of the network portion. An identification module of the system may identify one or more potential attack links causing the attack, and generate a list from the potential attack links. The identification module may iterate the list across the potential attack links to gather traffic statistics of the network portion, and determine one or more attack links based on the traffic statistics. User-specific data traffic throttling to the attack links may then be enforced by a throttling module of the system to mitigate the attack.

Abstract: Technologies are generally described to implement loopback simulation of inter-core messages in multicore processors. In some examples, a multicore processor may execute one or more processes, where each process communicates with other processes on or off the processor. Messages originating from processes on the multicore processor and destined for other processes on the multicore processor may be intercepted by a loopback simulator executing on the multicore processor. The loopback simulator may then redirect the intercepted messages to the destination processes on the multicore processor without the messages leaving the multicore processor.

Abstract: Technology is described for user assembly of lightweight user interfaces for games, e.g., massively multiplayer online games. The technology can include a set of pre-selectable action modules; an interface element, a messaging element, and a display element for each pre-selectable action module; and a component configured to enable a user to select a subset from the set of pre-selectable action modules. A first subset of the pre-selectable action modules can provide a different user interface than a second subset of the pre-selectable action modules when at least one pre-selectable action module is in the first subset but not the second subset. Action modules may be capable of communicating using a messaging platform with at least one server computing device and relates to a massively multiplayer online gaming system operating at a server computing device.

Abstract: Systems and methods for modulating dynamic optimizations of a computer program are disclosed. One method includes receiving an intermediate representation (IR) of machine executable instructions, optimizing the received IR to generate a first optimized IR prior to the machine executable instructions being generated by a runtime compiler, optimizing the received IR to generate two or more alternative optimizations for the IR, wherein the two or more alternative optimizations generating two or more optimized IRs are optimized at different optimization points based at least in part on information generated during execution of the first optimized IR in a runtime environment different optimization strategies, and modulating between the two or more alternative optimizations for the IR to use different ones of the alternative optimizations during execution of the machine executable instructions at a frequency based at least in part on a degree of difference between the two or more optimized IRs.

A virtual machine handler may receive a request that includes an instruction. The instruction may include a port and a data block identifier. The virtual machine handler may generate a modified request. The modified request may include the port, a block portion identifier and an identification of a comparator. The virtual machine handler may send values identified by the block portion identifier to the comparator. The virtual machine handler may receive an exit indicator from the comparator that indicates whether the virtual machine should exit the core.

Abstract: Technologies related to dynamic reconfiguration of programmable hardware are generally described. In some examples, coprocessor regions in programmable hardware such as a Field Programmable Gate Array (FPGA) may be dynamically assigned to transition the FPGA from a starting arrangement of coprocessor regions to an efficient arrangement. A placement algorithm may be executed to determine the efficient arrangement, and a path finding algorithm may be executed to determine path finding operations leading from the starting arrangement to the efficient arrangement. The path finding operations may be performed to implement the transition.

Abstract: Technologies related to cache-influenced video games are generally described. In some examples, the content of video game outputs as experienced by players of a video game may be adaptively modified to make more effective use of digital assets that are loaded in a computing system cache. Cache-influenced video games may increase cache use by increasing use, within a video game, of digital assets in a cache relative to assets not in the cache, e.g., assets that are on disk or in database storage. Cached digital assets can be retrieved more efficiently than assets stored elsewhere, and therefore video game performance may be improved.

Abstract: The present disclosure relates to technologies to deter side channel data center attacks. An example method may include receiving an incoming packets destined for a network, grouping, at a gateway, the incoming packets into groups, wherein a size of the groups is based on predetermined statistics, and wrapping the groups into packages of normalized size.

Abstract: Technologies are generally described to implement intrusion detection based on smart power background. In some examples, upon detection of an attempt to access a resource, a power line ambiance may be determined at a location of a device on which the attempt to access the resource is executed. The power line ambiance may be based on a connection of the device and/or one or more other devices at the location to a power line. The captured/received power profiles may identify device signatures enabling generation of a digest of the location. An intrusion detection system (IDS), may receive the digest of the location and compare the digest to previous digests associated with an authorized client of the resource to evaluate an authenticity of the attempt. If the authenticity of the attempt is suspicious, the IDS may elevate security by employing one or more verification levels and/or one or more authentication techniques.

Abstract: Technologies are generally described for controlling a flight path of a UAV based image capture system for solid modeling. Upon determining an initial movement path based on an estimate of a structure to be modeled, images of the structure to be modeled may be captured and surface hypotheses formed for unobserved surfaces based on the captured images. A normal vector and a viewing cone may be computed for each hypothesized surface. A set of desired locations may be determined based on the viewing cones for the entire structure to be modeled and a least impact path for the UAV determined based on the desired locations and desired flight parameters.

Abstract: Technologies are provided for locally installing remotely-served API instances. In some examples, a scale-out service may receive a request to provide an installation of a remotely-served API at a particular datacenter. In response to a determination by the scale-out service that a local instance of the remotely-served API can be installed at that datacenter, the scale-out service may install the local instance and route requests to that API from the datacenter to the local instance instead of the remotely-served API.
