An output layer may be created by capturing the at least one layer without capturing unselected layers. The output layer may include output frames captured at an initial frame rate of the local device. A desired output frame rate may be determined for the output layer. The initial frame rate of the output layer may be converted to the desired output frame rate. The output layer may be transmitted at the desired output frame rate to the media hosting service for presentation at a remote device.

Abstract: Functionality is disclosed herein for integrating a program code marketplace and a service provider network. A program code marketplace system is configured to provide a program code marketplace through which developers or other users can list program code for sale. Program code offered through the program code marketplace may have an associated execution environment definition that defines an execution environment for the program code. A request may be received to deploy program code available through the program code marketplace to a service provider network for execution. In response thereto, the execution environment definition may be utilized to create an execution environment in the service provider network. The program code may then be deployed to the execution environment in the service provider network for execution. The program code marketplace may integrate with other systems, such as a payments system, for processing micropayments for program code available through the program code marketplace.

Abstract: Systems and methods for monitoring Web page content associated with processing a resource request are provided. A client computing device generates a sample image corresponding to a set of resources rendered in response to a resource request. A processing component, such as an image analysis component, then compares the sample image with an averaged reference image to identify a compared image. The averaged reference image is determined from averaging a pixel intensity value for each pixel in a first reference image with a pixel intensity value for each pixel in a second reference image. These first and second reference images both correspond to the same set of requested resources. The processing component then weights the compared image to produce a weighted compared image and determines whether a sum of the intensity values for each pixel in the weighted compared image exceeds a threshold. Aspects of systems and methods for generating an alert message if the threshold is exceeded are also provided.

An output layer may be created by capturing the at least one layer without capturing unselected layers. The output layer may include output frames captured at an initial frame rate of the local device. A desired output frame rate may be determined for the output layer. The initial frame rate of the output layer may be converted to the desired output frame rate. The output layer may be transmitted at the desired output frame rate to the media hosting service for presentation at a remote device.

Abstract: An electronic device screencasts media content. The screencasting includes selecting a media content layers to include in an encoded stream. An output layer is created by capturing the selected media content layers without capturing unselected layers (although these unselected layers may still be presented locally by the electronic device). The output layer is encoded into a format compatible with a media hosting service to create the encoded stream, which is transmitted to the media hosting service for presentation at a remote device.

An application and first application metadata are received, and the application is scanned to identify second application metadata. The first and second application metadata are added to a search index corresponding to a plurality of applications offered via an application marketplace system. A search query is received, and a search of the search index is performed for the search query. One or more search results are generated from the search.

Abstract: An exemplary embodiment for translating requests from a client application includes a network server that is directed to receive a request from the client application and provide a customized response to the client application. The client application includes additional headers in the request which are not standard for an application protocol used in transmitting the request in order to transmit additional relevant information to the network server to get the customized response.

Abstract: Systems and methods provide logic facilitating an interaction between a networked server and multiple, unrelated devices. In one implementation, a computer-implemented method enables a user of a device to interact with or control multiple, unrelated devices across a cloud computing environment using a networked server. The method includes receiving, at the networked server, an instruction from the control device. A corresponding instruction understandable by an unrelated controlled device is generated by the networked server, and the corresponding instruction is operable to cause the controlled device to perform the received instruction. The networked server may transmit the corresponding instruction to the controlled device.

Abstract: A server system that hosts an electronic catalog of digital content items uses behavioral data to predictively select digital content items to proactively deliver to mobile devices of users. The digital content items may, for example, include mobile applications, mobile application components or add-ons, e-books, music tracks, and/or videos. An application component that runs on the mobile devices caches the proactively delivered content items in anticipation that they will be requested by the associated users. In some embodiments, the system supports off-line purchases of cached digital content items such that a user can purchase cached digital content items on the mobile device when no network connection is available.

Abstract: Disclosed are various embodiments for taking measurements associated with the execution of an application on one or more client devices. A measurement policy and/or a transmission policy may be defined by a developer with associated with an application. The measurement policy and/or transmission policy may be used by the one or more client devices in taking measurements, aggregating measurements into measurement collections, and/or transmitting measurements. The measurements may be used in the derivation of statistical information.

Abstract: Metrics data is generated and gathered based on users' use of mobile device applications. The metrics data may be cached by a mobile app store client on the users' mobile devices before being transmitted to a network application system which may be associated with an electronic catalog through which users can download mobile applications. The network application system may store user metrics information, aggregate that information, and perform analysis of the information. Resulting data may be displayed to users visiting product detail pages for mobile applications. The system may also generate reports to application developers based on how the users of their applications are interacting with the applications.

Abstract: This disclosure is directed to providing notifications to mobile devices, which may piggy-back on other communications exchanged between a mobile device and one or more servers. By piggy-backing, or otherwise adding small amounts of additional data to routine communications, the mobile device may avoid polling the server for notifications of pending messages for the mobile device or reduce a frequency of polling for the notifications. When polling is used to supplement the piggy-backing, a frequency of the polling may be based on a variable threshold amount of time.
