Inheritance in sample array multitree division
A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision. |

Capturing and replaying application sessions using resource files
A capture and replay system identifies images displayed during an application session. A parser may generate Hypertext Markup Language (HTML) code from an application resource file or from the JSON post made by the application. A replay engine may use the HTML code to recreate at least some of the screens displayed during the application session.

Key resource prefetching using front-end optimization (FEO) configuration
Front-end optimization (FEO) configuration information is leveraged to identify “key” resources required to load other pages on a site, and to automatically cause key resources to be prefetched to a server, and to the browser. In this approach, an FEO analyzer uses knowledge of configured optimization templates to determine the key resources required to load pages for each template. The key resources for pages belonging to other optimization templates are then selectively prefetched by other pages. In a preferred approach, the FEO analyzer provides an edge server cache process a list of key resources and instructions to prefetch the key resources, as well as instructions to rewrite the HTML of the page to include instructions for the browser to prefetech the key resources. On the client, key resources are prefetched if missing from a cache on the browser. Key resources preferably are stored in the browser's HTML5 local storage cache. |

System and method for service discovery in a large network
Service discovery is accomplished across a network with reduced traffic. Network devices often receive multicast discovery requests for various protocols and/or services, which increase network traffic and degrade network performance. Here, though, a server maintains a membership list for a particular protocol. The server populates the membership list with subnet devices that confirm the particular protocol. Whenever the server receives a discovery request associated with the protocol, the server need not clog its subnet with multicast requests. Instead, the server need only retrieve the membership list that is associated with the protocol. The membership list contains the subnet addresses assigned to the subnet devices that confirm the particular protocol. |

The anchor master may adjust the synchronization parameters to avoid conflict with another hierarchy. Each device issues beacons (e.g., heartbeats, discovery beacons) that identify the number of devices synchronized with the reporting device, which allows the anchor master to calculate the total number of cluster members. Devices may also report details of a neighboring cluster (e.g., its synchronization parameters) via a beacon or some other communication. |

Protection for computing systems from revoked system updates
A computing system may be protected from revoked system updates. A computing system receives an object and scans it for revocation updates to a security structure of the computing system. The security structure is a monotonically nondecreasing collection of segments containing data on whether a system update is revoked and a system update's status as revoked signifies the revoked system update can no longer be used by the computing system. Based upon scanning the object, the computing system identifies and validates a revocation update. The computing system resolves the revocation update by applying the revocation update to the security structure, by adding or changing one or more segments of the security structure identified by the revocation update, in response to determining that the revocation update is valid, or by denying application of the revocation update to the security structure in response to determining that the revocation update is invalid. |

Secure permissioning of access to user accounts, including secure deauthorization of access to user accounts
A permissions management system is disclosed for enabling a user to securely authorize a third-party system to access user account data and initiate transactions related to a user account, without disclosing to the third-party system account credentials. The system enables the user to also securely de-authorize the third-party system.

Behavior-based filters for signaling system number 7 networks
Concepts and technologies disclosed herein are directed to behavior-based filters for signaling system number 7 (“SS7”) networks. According to one embodiment disclosed herein, a behavior-based SS7 filter executed by a processor can receive SS7 traffic. The behavior-based SS7 filter can determine a behavioral characteristic from the SS7 traffic and can compare a behavior of the SS7 traffic, based upon the behavior characteristic, to a behavior profile. The behavior-based SS7 filter also can determine whether the behavior of the SS7 traffic fits within a tolerance threshold of the behavior profile. If the SS7 traffic fits within the tolerance threshold, the behavior-based SS7 filter can instruct a signal transfer point (“STP”) to which the SS7 traffic is directed to allow routing of the SS7 traffic. If, however, the SS7 traffic does not fit within the tolerance threshold, the behavior-based SS7 filter can instruct the STP to deny routing of the SS7 traffic. |

Optimizing shading process for mixed order-sensitive and order-insensitive shader operations
A graphics processing unit (GPU) includes programmable shader hardware and grouping hardware. The grouping hardware receives pixels collected from a set of primitives, wherein pixel locations of each primitive have been obtained through rasterization of a set of vertices of the primitive. The grouping hardware also groups the pixels into a set of groups having a sequential order. None of the pixels in each group overlapped with each other in a display and overlapped pixels belong to different groups. The programmable shader hardware performs order-insensitive shader operations on the groups according to a first subset of an instruction set defined for a programmable shader, with two or more of the groups processed in parallel. The programmable shader hardware also performs order-sensitive shader operations on each of the groups in the sequential order according to a second subset of the instruction set defined for the programmable shader. |
