    Abstract: In various embodiments, a perceptual quality application determines an absolute quality score for encoded video content viewed on a target viewing device. In operation, the perceptual quality application determines a baseline absolute quality score for the encoded video content viewed on a baseline viewing device. Subsequently, the perceptual quality application determines that a target value for a type of the target viewing device does not match a base value for the type of the baseline viewing device. The perceptual quality application computes an absolute quality score for the encoded video content viewed on the target viewing device based on the baseline absolute quality score and the target value. Because the absolute quality score is independent of the viewing device, the absolute quality score accurately reflects the perceived quality of a wide range of encoded video content when decoded and viewed on a viewing device.

    Abstract: A method and system for discovering and testing security assets is provided. Based on source definition data describing sources to monitor on the one or more computer networks, an example system scans the sources to identify security assets. The system analyses the security assets to identify characteristics of the server-based applications. The system stores database records describing the security assets and the identified characteristics. The system queries the database records to select, based at least on the identified characteristics, one or more target assets, from the security assets, on which to conduct one or more security tests. Responsive to selecting the one or more target assets, the system conducts the one or more security tests on the one or more target assets. The system identifies one or more security vulnerabilities at the one or more target assets based on the conducted one or more security tests.

    Abstract: A certificate orchestration system for digital certificate and encryption key management is provided herein along with associated methods. The system includes a certificate orchestration server having a processing device in communication with a coupled storage system that is coupled to the certificate orchestration server. The system further includes an interface provided by the certificate orchestration server to a client device; and a database to store digital certificates and keys. The certificate orchestration server is configured to receive a request from the client device to generate a public key, receive the public key from a third-party certificate authority system over an external network, store the public key in the coupled storage system. The coupled storage system is not directly connected to the client device.

    Abstract: In various embodiments, a benchmarking engine automatically tests a data store to assess functionality and/or performance of the data store. The benchmarking engine generates data store operations based on dynamically adjustable configuration data. As the benchmarking engine generates the data store operations, the data store operations execute on the data store. In a complementary fashion, as the data store operations execute on the data store, the benchmarking engine generates statistics based on the results of the executed data store operations. Advantageously, because the benchmarking engine adjusts the number and/or type of data store operations that the benchmarking engine generates based on any changes to the configuration data, the workload that executes on the data store may be fine-tuned as the benchmarking engine executes.

    Abstract: Embodiments provide techniques for testing a plurality of variations of a user experience on a subscription-based online site, where each of the plurality of variations is distinct from other variations in the plurality of variations. Each of a plurality of users is assigned to one of the plurality of variations. For each of a plurality of user requests received during a predetermined window of time, embodiments determine one of the plurality of variations for use in processing the user request, based on a user associated with the user request, and process the respective user request using the determined variation. Long-term user metric information relating to subscription services for the subscription-based online site is determined, with respect to the plurality of users. Embodiments then rate at least one of the plurality of variations, based on the determined long-term user metric information.

    Abstract: One embodiment of the present invention sets forth a technique for correcting color values. The technique includes downsampling first color space values to generate downsampled color space values and upsampling the downsampled color space values via a first upsampling filter type to generate second color space values. The technique further includes modifying at least one component value included in the downsampled color space values based on a first component value included in the first color space values, a second component value included in the second color space values, and an approximation of a nonlinear transfer function. The technique further includes at least one of (i) storing an indication of the first upsampling filter type in conjunction with a video bitstream associated with the at least one component value, and (ii) transmitting the indication of the first upsampling filter type to a receiving device in conjunction with the video bitstream.
