Abstract: Organizations may employ private computer networks to enable customers to place a telephone call to customer service agents (CSAs). To maintain high customer service, it may desirable to expand the private computer network's ability to respond to customer calls on-demand. One or more requests for additional telephony resources may be submitted to a telephony resource allocation service in communication with a configurable network service. The telephony resource allocation service may determine telephony resources available for allocation to the private computer network and facilitate communication between the configurable network service and the private computer network. In this manner, additional computer private network extensions executing instances of call distribution services may also be generated and configured.

Abstract: Systems and methods involve receiving a connectivity subscription request for one or more connections, such as a virtual private network (VPN) connection. A connectivity subscription request may be received through an application programming interface (API) call and the connectivity subscription request may indicate that a user associated with a connection wants to receive a notification when a connectivity event occurs. A connectivity event can occur when changes to the connection are detected, such as when the connection becomes active, when the connection becomes inactive, or when one or more tunnel connections related to the connection becomes disconnected. A potential problem associated with the connectivity event may be detected and a potential solution to the problem may be determined. The potential solution can be sent to a user associated with the connectivity event.

Abstract: Embodiments may include a load balancer that receives a request packet sent by a remote client to an original destination address of multiple network addresses serviced by the load balancer, and selects according to a load balancing protocol, a host computer of a plurality of host computers to process the request. The load balancer may, from among a plurality of ports on the selected host computer, select a particular port having a one-to-one association with the original destination address, the association specified by mapping information accessible to the load balancer, and send the request packet to the selected port on the selected host computer. The mapping information accessible to the selected host computer specifies a one-to-one association between the selected port and the original destination address. Sending the request packet to the selected port conveys that address to the selected server without that address being included in that packet.

Abstract: A computer-generated puzzle game can enable any appropriate image (e.g., a still image, video, or animation) to be used as a puzzle image. The puzzle game can utilize a framework including a portion of the puzzle image such that the user can determine where to place the puzzle pieces without having to see a version of the final image, which can save display real estate as well as provide suspense and additional challenge for the user. The puzzle pieces also can include a portion of the image, such that the player can determine where the pieces are to be placed in the framework without having to worry about rotating or properly positioning the pieces, which can be difficult on at least certain computing devices.

Abstract: Techniques are described for providing client computing nodes with enhanced access to data from remote locations, such as by providing and using local capabilities specific to the remote locations. In at least some situations, the access of a client computing node to data from a remote location may be enhanced by automatically performing activities local to the client computing node that improve the efficiency of communications sent between the client computing node and the remote location. As one example, access to data from a remote service may be enhanced by locally performing activities specific to the remote service, such as by using information about the remote service's internal mechanisms to cause the desired data to be provided from internal storage devices of the remote service without passing through front-end or other intermediate devices of the remote service while traveling to the client computing node.

Abstract: A user account may be throttled to restrict access once aberrant behavior is detected. Upon receiving a request to access the user account, a determination of whether the user account is in a throttled state may be made. In some aspects, when the user account is not in a throttled state, user account access may be determined based at least in part on an access credential. Further, in some aspects, when the user account is in a throttled state, user account access may be determined based at least in part on an access credential and other client information associated with the user account.

Abstract: Disclosed are various embodiments for adjusting the encoding of a video signal into a video stream based on user attention. A video signal generated by an interactive application is encoded into a video stream. A temporary lapse of attention by a user of the interactive application is predicted. The encoding of the video signal into the video stream is adjusted from an initial state to a conservation state in response to predicting the temporary lapse of attention by the user. The conservation state is configured to conserve one or more resources used for the video stream relative to the initial state.

Abstract: Virtual firewalls may be established that enforce sets of policies with respect to computing resources maintained by multi-tenant distributed services. Particular subsets of computing resources may be associated with particular tenants of a multi-tenant distributed service. A tenant may establish a firewalling policy set enforced by a virtual firewall for an associated subset of computing resources without affecting other tenants of the multi-tenant distributed service. Virtual firewalls enforcing multiple firewalling policy sets may be maintained by a common firewalling component of the multi-tenant distributed service. Firewalling policy sets may be distributed at multiple locations throughout the multi-tenant distributed service. For a request targeting a particular computing resource, the common firewalling component may identify the associated virtual firewall, and submit the request to the virtual firewall for evaluation in accordance with the corresponding firewalling policy set.

Abstract: A user can emulate touch screen events with motions and gestures that the user performs at a distance from a computing device. A user can utilize specific gestures, such as a pinch gesture, to designate portions of motion that are to be interpreted as input, to differentiate from other portions of the motion. A user can then perform actions such as text input by performing motions with the pinch gesture that correspond to words or other selections recognized by a text input program. A camera-based detection approach can be used to recognize the location of features performing the motions and gestures, such as a hand, finger, and/or thumb of the user.

Abstract: Disclosed are various embodiments for inhibiting or preventing automated data extraction from network pages. A source for a network page having a document structure is obtained. An obfuscated network page is generated from the network page by altering the document structure to inhibit automated extraction of data. The obfuscated network page is configured to have a visual appearance that is the same as that of the network page when rendered by a client for display. The obfuscated network page is sent to the client in response to a request from the client for the network page.

Abstract: Systems and methods for incrementally building tests and test frameworks may enable cost reduction and/or code sharing between teams testing various products (or features thereof) in different domains or of different product types. Test frameworks may be layered into standalone sub-framework packages that build on each other and whose object classes inherit object classes of lower layers. Sub-framework packages may provide generic utilities, domain-specific testing operations, application-specific testing operations, or operations for specific application types (e.g., web services). Test clients may plug into test frameworks at any layer to exercise features of a product under test. Tests may be built from components at multiple levels of abstraction, and may include test operations, test steps that include multiple test operations, and tests that include multiple test steps. Implementation details of products to be tested may only be visible to, and/or exercised by, the lowest-level elements of the tests (e.
