Methods and systems for selecting content for a computing device are described. In some embodiments, the method comprises: receiving, by one or more processors of a data processing system, from a client computing device, location data of the client computing device; identifying, by the data processing system, an entity around a location of the client computing device; identifying, by the data processing system, a radius threshold corresponding to the entity based on a performance metric criterion; determining, by the data processing system, that a distance between the client computing device and the entity is less than the radius threshold corresponding to the entity; and transmitting, by the data processing system, responsive to the determination, to the client computing device, a content item associated with the entity.

Dynamic radius threshold selection

The disclosure relates to dynamically selecting a radius threshold for a device. The system identifies, based on sensor data detected by a sensor of the device, a location of the device. The system generates a feature representation for each of a plurality of features based on a query input into the device, the location of the device, and a plurality of entity locations corresponding to the query. The system accesses a data structure storing optimum radii correlated with a presence of the plurality of features and a corresponding performance metric based on network activity. The system determines the radius threshold based on the optimum radii and the plurality of features. The system identifies an eligible entity location having a distance from the device that is within the radius threshold. The system selects, for display on the device, a content item for the eligible entity location.

In a cloud computing environment, a production server virtualization stack is minimized to present fewer security vulnerabilities to malicious software running within a guest virtual machine. The minimal virtualization stack includes support for those virtual devices necessary for the operation of a guest operating system, with the code base of those virtual devices further reduced. Further, a dedicated, isolated boot server provides functionality to securely boot a guest operating system. The boot server is isolated through use of an attestation protocol, by which the boot server presents a secret to a network switch to attest that the boot server is operating in a clean mode. The attestation protocol may further employ a secure co-processor to seal the secret, so that it is only accessible when the boot server is operating in the clean mode.

Attestation protocol for securely booting a guest operating system

A method, system and program product comprise receiving spectrum data from one or more WiFi communication devices being configured to be operable as observers of transmissions within a frequency band associated with a WiFi communication system. The spectrum data at least comprises signal levels and timing information for WiFi communication signals and non-WiFi signals observed within the frequency band. WiFi interferers are distinguished using at least the signal levels and timing information for the non-WiFi signals. A real-time interference impact on the observed WiFi communication signals for each of the distinguished WIFi interferers is determined.

Embodiments of the claimed subject matter provide an approach to managing the power state of wireless network devices in a wireless network. Embodiments include a process for modifying the scheduling of data distribution device by referencing the data buffer in an access point for data intended for a wireless network client operating under a power-saving mode, and re-arranging the distribution queue of the access point to be granted priority for a time which coincides with the delivery of a polling beacon to the power-saving wireless client. Other embodiments include a method to create virtual access points for a particular usage, and to leverage access points in a wireless network for particular usages of devices in range.

Network assisted power management

A computer-implemented method for scheduling a packet for transmission in a wireless local area network can be used to account for hidden and/or exposed terminals. The method includes determining whether the packet is to be transmitted to a computing device through a wireless access point that is in conflict with at least one other computing device associated with a different access point. The method further includes determining whether there is a conflicting packet scheduled to be transmitted for any conflicting computing devices associated with a different access points and scheduling the packet for transmission based on any conflicting packets. The method yet further includes forwarding the packet to a wireless access point at the scheduled time.
