Abstract: The disclosure relates to technology for predicting file access patterns by identifying one or more files stored in a first cache and one or more pages associated with each of the one or more files in a second cache. The one or more files in the first cache are evicted based on a first eviction policy and, for each of the one or more files, the one or more pages in the second cache are evicted based on a second eviction policy. Access patterns of the one or more files based on the first and second eviction policies may then be predicted.

Abstract: A wireless interface system includes a wireless network interface, with a virtual Ethernet interface, that is configured to transmit and receive signals over a wireless channel using a predetermined wireless technology protocol. A method for abstracting a wireless interface protocol to an Ethernet protocol includes detecting, with a wireless network interface, access by a wireless device using the wireless interface protocol. A virtual Ethernet interface is created having an associated Ethernet interface ID. The wireless device ID is associated with the Ethernet interface ID in a table in memory. A payload from the wireless device is transmitted over the wireless technology protocol. The payload is transmitted to the virtual Ethernet interface using the Ethernet protocol.

Abstract: A method comprising receiving, by a processing thread executing on a host server, a container request to create a container on the host server by employing a container engine, wherein the container request indicates a first resource constraint and a second resource constraint for executing an application within the container, directing, by the processing thread, the container engine to create an operating environment for the container according to the first resource constraint and to execute the container on the host server, reserving, by the processing thread, a first resource from an operating system (OS) of the host server according to the second resource constraint of the container request, and updating dynamically, by the processing thread, the operating environment of the container to enable the container to directly utilize the reserved first resource for execution of the application to meet the second resource constraint of the container request.
