Abstract: The disclosure describes a proxy server application that supports the dynamic modification of proxy rules implemented by a proxy server. The proxy rules implemented by the proxy server specify network behaviors to be performed at various points during the handling of requests from client applications. A proxy server implements the proxy rules by processing one or more user-generated network traffic filters for managing network traffic. In an embodiment, users generate network traffic filters by creating network traffic filter source code that specify processing steps to be performed by a proxy server relative to network messages the proxy server receives. In an embodiment, user-generated network traffic filters may be added, removed, reordered, or otherwise modified in a proxy server application at runtime in order to respond to current network conditions or to achieve other desired proxy configurations.

Abstract: One embodiment of the present invention sets forth a technique for identifying active streaming connections associated with a particular user account. Each active streaming connection transmits heartbeat packets periodically to a server that tracks the receipt of the heartbeat packets. If, for a particular streaming connection, the server stops receiving heartbeat packets, then the server is able to infer that the streaming connection has been terminated.

Abstract: One embodiment of the present invention sets forth a technique for streaming digital media content with transition effects. Audio data may be modulated and received by the streaming device for an audio fade-in effect. Similarly, video data may be modulated to perform various visual effects. Such a technique allows for fading-in of audio and/or video, fading-out of audio and/or video, and effects that blend audio from different content and video from different content during a transition from one digital media content to a different digital media content or within the same digital media content. The modulated audio and video data to generate the audio or video effect during a transition may be precomputed or computed in real-time and transmitted to the streaming device. The streaming device switches between original unmodulated content streams and effect content streams when transitions are detected.

Abstract: Increasingly, children are consuming digital content on computers, laptops, tablets, and even smartphones. The sheer volume of content available to children can be daunting for parents to manage and filter for their children. Primitive filtering mechanisms based on a target audience age can be used to eliminate some content based on a child's chronological age. However, children develop at different rates so that even children of the same chronological age can have different developmental stages and so have different preferences for content they consume. Systems and methods described herein provide children with access to developmental stage-appropriate content in a developmental stage-appropriate user interface. The developmental stage-appropriate interface includes representations of the content that are developmental stage-appropriate and surrounding elements that are also developmental stage-appropriate. The user interface can include or not include functional elements based on the developmental stage of the user.

Abstract translation: 儿童越来越多地在电脑，笔记本电脑，平板电脑甚至是智能手机上都在使用数字内容。 为儿童提供的绝大多数内容对于家长来说是非常困难的。 基于目标受众年龄的原始过滤机制可以用于根据孩子的年龄来消除一些内容。 然而，孩子们以不同的速度发展，所以即使是同一时代年龄的孩子也可以有不同的发育阶段，所以对消费的内容有不同的偏好。 本文描述的系统和方法使儿童能够在发展阶段适当的用户界面中访问适合发展阶段的内容。 发展阶段适当的界面包括发展阶段适当的内容的表示以及也是发展阶段适当的周围元素。 用户界面可以包括或不包括基于用户的发展阶段的功能元素。

Abstract: In an approach, a target computing device receives a pairing request from a controller computing device, the pairing request including controller credentials that were previously received by the controller computing device from an authentication server computer and encrypted under a service key. The target computing device forwards the pairing request to the authentication server, the authentication server computer being configured to return a pairing response based at least in part on the controller credentials. The target computing device receives the pairing which includes a shared secret encrypted under a target device key and the same shared secret encrypted under a controller key. The target computing device decrypts the shared secret encrypted under the target device key and forwards the shared secret encrypted under the controller key to the controller device. Using the decrypted shared secret, the target computing device establishes a secure connection to the controller computing device.

Abstract: Techniques are disclosed for reclaiming resources within a distributed computing system. A reclamation application searches the distributed computing architecture for unused resources, classifies the unused resources, and determines an expiration period based on the classification. The reclamation application determines a candidate owner of the resource based on one or more characteristics of the resource. The reclamation application then notifies the candidate owner that the resource is to be reclaimed unless claimed by the candidate owner within the expiration period. If the candidate owner claims the resource within the expiration period, then the reclamation application terminates the reclamation of the resource. If the candidate owner does not claim the resource within the expiration period, then the reclamation application reclaims the resource after the duration of the expiration period. Advantageously, reclaiming resources results in more efficient utilization of resources, lower operation and maintenance costs, and improved system security.
