Abstract: A social networking system selects a set of groups for presentation to a user of the social networking system. To select groups, the social networking system determining scores for various groups representing a likelihood of the user interacting with the groups. When determining a score for a group, the social networking system accounts for a likelihood of the user providing content to the group as well as the user accessing or viewing content associated with the group. Based on the scores, one or more groups are selected and presented to the user. Additionally, the social networking system may apply one or more diversity rules so that the selected groups have a variety of characteristics.

Abstract: A network-accessible computer comprises a network-communications interface configured to receive player-position data via a computer network. The player-position data indicates a multi-dimensional position for each of a plurality of players participating a sporting event. The network-accessible computer further comprises a logic machine configured to derive auxiliary information from at least the player-position data, the auxiliary information not included in the player-position data and indicating specific attributes for one or more of the plurality of players during a period of game activity in the sporting event. The logic machine packages the auxiliary information with the player-position data into a client-readable data package usable by a client computing device to construct a user interface visualizing at least the player-position data and auxiliary information. The logic machine sends the client-readable data package to the client computing device via the network-communications interface.

Abstract: An altimeter system is provided. The altimeter system includes a receiver mixer including an antenna-input and a local-oscillator-input; a transceiver circulator communicatively coupled to an antenna via a transmission line having a selected length and communicatively coupled to the antenna-input of the receiver mixer; and a transmitter configured to output a transmitter signal to the antenna via the transceiver circulator. The transmitter signal is frequency modulated with a linear ramp. The transmitter is communicatively coupled to the receiver mixer to input a local oscillator signal at the local-oscillator-input of the receiver mixer. The receiver mixer is communicatively coupled to input a target-reflected signal from the antenna at the antenna-input of the receiver mixer. The selected length of the transmission line is set so that a composite-leakage signal at the antenna-input of the receiver mixer has a linear phase across a sweep bandwidth.

Abstract: A social networking system displays information about a user via a timeline included in a profile page. Narrative data about a user stored in a social networking system, including data about the user and social network activities related to the user is accessed. Timeline units summarizing information about the user are generated from the narrative data. When a viewing user requests a profile page, timeline units are displayed based information related to the viewing user and interactions with the profile page by other users connected to the viewing user. Users that administer the profile page are presented with additional information when viewing the profile page, allowing the administering users to modify appearance of the timeline or to identify actions for an administering user to take to increase interaction with the profile page.

Abstract: Exemplary methods, apparatuses, and systems receive data describing a first software component used by a software product and vulnerability data describing a vulnerability in the first software component. A vulnerability score is calculated for the software product based upon the vulnerability data for the first software component. The vulnerability score is recalculated for the software product based upon receiving an updated status of the vulnerability in the first software component from bug tracking software, a waiver of the vulnerability of a software component, the addition of another software component, or another update to the software product or component(s). The task of remediation of the vulnerability in the first software component can be assigned to a user and tracked. A user interface is provided to enable users to monitor the vulnerabilities of software products or components.

The devices can be designed to provide synchronization (time value, frequency, and phase) among a network of routers, with signal paths of several meters, thereby providing an accurate time base suitable for exacting audiovisual applications.

Abstract: Methods and apparatus for dynamically adjusting the amount of power (or current) distributed to one or more connected devices via electrical interfaces. In one embodiment, the apparatus comprises a first module adapted to detect current drawn by a first set of ports, and a second module adapted to adjust the current provided to a second set of ports based on the detected current. The second module is also optionally adapted to distribute unreserved current among the devices according to an allocation protocol. In the exemplary context of a plurality of interconnected serial bus devices, the invention enables a device to draw more current than that required to be reserved for that device (such as to comply with a specification such as USB), yet without increasing the total amount of power which must be dedicated to the serial ports as a whole. Power supply efficiency may also be advantageously optimized.
