Abstract: Embodiments described herein relate to adjusting performance of a virtualization layer to reduce underutilization of a physical device. The virtualization layer virtualizes access to the device for a VM. When a guest in the VM makes a request to a virtual device, the virtualization layer and the device work together to satisfy the request. Some time is spent by the virtualization layer (software/CPU time), for instance delivering the request from the VM to the physical device, mapping the request from the virtual device to the physical device, etc. Additional time is spent by the device in performing the request (device time). The software/CPU time relative to the device time serves as a basis for deciding whether to increase or decrease processing capacity of the virtualization layer (or a component thereof), thus reducing underutilization of the device and over-provisioning of processing capacity to the virtualization layer.

Abstract: A wireless communication device may wirelessly control an object, such as a physical device, directly or through interaction with a virtual representation (or placeholder) of the object situated at a predefined physical location. In particular, the wireless communication device may identify an intent gesture performed by a user that indicates intent to control the object. For example, the intent gesture may involve pointing or orienting the wireless communication device toward the object, with or without additional input. Then, the wireless communication device may determine the object associated with the intent gesture using wireless ranging and/or device orientation. Moreover, the wireless communication device may interpret sensor data from one or more sensors associated with the wireless communication device to determine an action gesture corresponding to a command or a command value. The wireless communication device may then transmit the command value to control the object.

Abstract: In an approach, when a pluggable database within a container database is transported to a new container database, the pluggable database is replaced with a proxy pluggable database storing forwarding information for the pluggable database. When a command is received that is to be executed on the proxy pluggable database, the database server handling the command uses the forwarding information stored within the proxy pluggable database to forward the command to a second database receiver responsible for the new container database for execution on the pluggable database. The result of executing the command is then returned to the first database server. Thus, application code which references the pluggable database within the original container database does not have to be rewritten to reference the new location and can remain agnostic as to the actual location of the pluggable database.

A file management service initiates operations to provide the move notification upon detecting the move operation to move the file from a source location to a destination location. A stakeholder is identified with an access to the destination location prior to executing the move operation to move the file from the source location to the destination location. After executing the move operation, a move notification is generated to inform the stakeholder of the move operation. The move notification provides information such as a description of the file, the source location, the destination location, and/or an identification of an initiator of the move operation. Furthermore, the move notification is transmitted to the stakeholder.

Abstract: A content delivery network has at least a first tier of servers. A content delivery method includes, at a first server in the first tier of servers, obtaining a request from a client for a resource. If the resource is available at the first server or at a peer of the first server, then the resource is served to the client from the first server. Otherwise, it is determined whether the resource is popular, and if the resource is determined to be popular, then the first server obtains the resource and the first server serves the resource to the client. If the resource is determined not to be popular, the server contacts a second server to obtain the resource, not in the first tier of servers, and the second server provides the resource to the first server. The first server is instructed not to cache the unpopular content.

Abstract: Methods and systems are disclosed for stateful backend drivers for security processing through stateless virtual interfaces within virtual machine (VM) host servers. A security application runs within a hosted VM, and a header is stored for the security application that includes a host backend identifier (BID). The VM sends a security processing request including the header through a stateless virtual interface to a backend driver. The backend driver compares the host BID within the processing request to host BIDs associated with the VM host server. If a match is found, security processing request is performed using one or more security engines within the VM host server. If a match is not found, the VM is identified as a migrated VM, and the header is updated to store a host BID associated with the VM host server. A timestamp for virtual queue creation is preferably used for the host BID.
