    Abstract: A modular network switch is disclosed. In an embodiment, removable interface modules and a switch circuit board (SMB) are housed in a chassis. Each of the interface modules includes a circuit board that is positioned in parallel with other interface modules. The SMB is oriented in a plane perpendicular to orientation planes of the interface modules, and the circuit boards are connected to the switch circuit board. A switch chip is electrically connected to SMB, and configured to switch network traffic between network connections of the interface modules. The chassis may include airflow regions separated by a divider with respective air intake vents. A power supply is housed in one of the regions and the SMB/interface modules are housed in another region. Power supplies provide power to the interface modules via a bus bar and provide power to the switch circuit board via a connection separate from the bus bar.

    Abstract: Low-cost network switches and other computing systems are described herein. A low-cost network switch can operate at a lower ambient temperature (e.g., 55° C.) than conventional switches, thereby enabling the use of lower cost components (e.g., optical components that are not rated for operation at up to 70° C.). The network switch can utilize a power bar pass-through card that provides power from an enclosure bus bar to components of the network switch in lieu of a power supply unit. Additionally, ports of the network switch can operate in a 2×50G mode in which a network switch port capable of communicating at 100 Gbps interfaces with two external ports each capable of communicating at 50 Gbps. Communication in 2×50G mode can be supported by a four-channel Y-cable, in which the four channels are utilized by the network switch port and fan-out to two channels to each of the two external ports.

    Abstract: Modular network switches and other computer systems are described herein. A modular network switch can include a latching device for installing and removing computer modules (e.g., line cards) from an associated cabinet or enclosure. The network switch can also include interconnected computer modules (e.g., line cards, fabric cards, control modules, etc.) that include circuit boards oriented parallel to the flow of cooling air through the cabinet in the absence of a backplane or midplane oriented perpendicular to the air flow. The absence of such backplanes and/or midplanes provides a more direct air flow path through the cabinet, thereby enabling a more efficient flow of cooling air and lower operating temperatures. Additionally, the network switch can include an orthogonal arrangement of data planes, control planes, and/or power planes that can be efficiently interconnected to increase operational speed and further facilitate the flow of cooling air through the computer cabinet.

    Abstract: An online system selects content items for presentation to viewing users of the online system based on a composite score associated with each content item that includes a quality component and a revenue component. The revenue component is based on a monetary amount an advertiser associated with the content item is willing to pay for each interaction with the content item by a prospective viewing user, while the quality component indicates the quality of the content item to the prospective viewing user. The quality component is predicted based on explicit user quality ratings received from viewing users for various content items previously presented to the viewing users, in which the viewing users have at least a threshold measure of similarity to the prospective viewing user and/or the various content items rated by the viewing users have at least a threshold measure of similarity to the content item being scored.
