Abstract:
Customers can utilize resources of a multi-tenant environment to provide one or more services available to various users. In order to simplify the process for these customers, the multi-tenant environment can include an infrastructure wherein a portion of the resources provide an authentication and/or authorization service that can be leveraged by the customer services. These resources can logically sit in front of the resources used to provide the customer services, such that a user request must pass through the authorization and authentication service before being directed to the customer service. Such resources can provide other functionality as well, such as load balancing and metering.
Abstract:
An attachment received from a webclient for a message in composition can be saved by an HTTP server in a storage system. Location information for the attachment can be stored in a database in a record associated with the webclient. If the HTTP server is unexpectedly unavailable, a backup HTTP server can locate the attachment using the record in the database and provide the attachment to a messaging server when the user is ready to send the message.
Abstract:
Techniques described herein include a platform for generating customized media content to a user. In some embodiments, a service provider may receive attribute data related to an environment in which a media file is to be presented. In some embodiments, the service provider may receive a user configuration setting indicating one or more preferences for media presentation. The service provider may store media content as separate components, with each component being separately adjustable. Upon receiving a request for particular media content, the service provider may generate a media file from the stored media content in accordance with the user configuration settings and/or environment attribute data.
Abstract:
Architectures and techniques are described to provide a number of options to exchange information related to deals via a plurality of channels. Each of the communication channels may be utilized to exchange communications about different aspects of acquiring and redeeming deals. The channel options may be related to categories of computing devices, operating systems executed by computing devices, one or more sites, various forms of communication, client device applications, etc. A service provider that offers deals on behalf of merchants may determine one or more options for each communication channel with respect to merchants offering deals and with respect individuals that may participate in deals offered by the service provider. After determining the channel options for a deal offered by a particular merchant and for individuals designated to receive information about the deal, communications with respect to the deal may be exchanged over the channels via certain channel options.
Abstract:
A wearable device may compress the skin of a user when worn, which may affect values determined using sensors of the device. To determine the effect of skin compression on the values, a time-of-flight signal, images, or frames of video data that depict a portion of the body having indentations from wearing the device may be acquired. Characteristics of the images, such as shadows associated with the indentations, may be processed using a machine learning algorithm or mathematical function to determine a depth of various portions of the indentations. Depth data from the time of flight signal may be used to refine or modify these determined depths. The amount of skin compression associated with the indentations may be used to modify signals acquired using sensors, or output a recommendation for a band or other method for securing the device.
Abstract:
A gift privacy module receives a request to display an order history associated with a user account. In response to the request, the gift privacy module displays the order history associated with the user account, while hiding at least a portion of order details associated with at least one entry identified as private in the order history.
Abstract:
Provided are systems and methods for reliable, out-of-order transmission of packets. In some implementations, provided is an apparatus configured to communicate with a network and a host device. The apparatus may receive messages from the host device at a send queue, where each message includes destination information. The apparatus may further determine, using the destination information and an identify of the send queue, a transport context associated with a destination on the network. The apparatus may further, for each message and using the transport context, generate a packet including the message and transmit the packet over the network. The apparatus may further monitor status for each transmitted packet.
Abstract:
A service allowing for obfuscation of identifiers such that the obfuscated identifier values are within a set of valid identifier values. The service allows for resources to be associated with an obfuscated identifier, and for clients to request information regarding obfuscated identifiers and resources associated to obfuscated identifiers.
Abstract:
Techniques described and suggested herein include systems and methods for precomputing regeneration information for data archives (“archives”) that have been processed and stored using redundancy coding techniques. For example, regeneration information, such as redundancy code-related matrices (such as inverted matrices based on, e.g., a generator matrix for the selected redundancy code) corresponding to subsets of the shards, is computed for each subset and, in some embodiments, stored for use in the event that one or more shards becomes unavailable, e.g., so as to more efficiently and/or quickly regenerate a replacement shard.
Abstract:
Satellites communicate with user terminals (UTs) based on accurate timing. A UT clock provides a pulse per second (PPS) signal to coordinate operation of the UT, such as transmitting data on an uplink at specified times. The clock may be disciplined by an external source that provides accurate and precise true time, such as a global navigation satellite system. The external source may sometimes be unavailable. The UT uses information about its location, satellite location, the ephemeris of the satellite, and timing data transmitted by the satellite, to calculate an estimated delay due to propagation, scintillation, and so forth. The timing data and estimated delay are used to determine a time correction. The time correction is applied to the timing data and used to determine estimated true time, that is then used to generate an alternate PPS signal. The estimated true time is used until the external source is available.
