Methods, apparatus, computer program products Geohash-based traffic management are provided. The method comprises receiving, by one or more processing units, respective operating status data of one or more vehicles travelling within a Geohash cell; generating, by one or more processing units, one or more service messages based on the received respective operating status data according to one or more service specifications; and providing, by one or more processing units, at least one of the one or more service messages responsive to a request from a vehicle travelling within the Geohash cell.

Geohash-based traffic management

According to one embodiment, a method, computer system, and computer program product for webpage replay is provided. The embodiment may include acquiring one or more commands each indicating changes of at least one virtual Document Object Model (DOM) node of a virtual DOM of a webpage corresponding to a timestamp for a session. The embodiment may include determining one or more virtual DOM differentials corresponding to respective timestamps for the session based on the one or more commands and a first data dictionary. The first data dictionary is created based on a base virtual DOM of the webpage including a plurality of virtual DOM nodes. The embodiment may include generating one or more patched virtual DOMs of the webpage corresponding to respective timestamps for the session. The embodiment may include replaying the webpage for the session based on the base virtual DOM and the patched virtual DOMs.

Replaying a webpage based on virtual document object model

A method includes receiving, by a device, a request to input information through a virtual canvas, the device includes a projector and a camera, the virtual canvas providing an input space to a user of the device, the virtual canvas includes a region of a blank surface illuminated by the projector, based on the received request, enabling the projector and the camera, detecting a distance between the device and the virtual canvas, based on the detected distance, adjusting the projector and the camera to focus on the virtual canvas, capturing a movement made by an object on the virtual canvas, the movement is associated with the information being input, converting the movement into a plurality of frames, each frame is associated with the movement, processing the plurality of frames to obtain the input information, and projecting the input information on the virtual canvas.

Inputting information using a virtual canvas

Embodiments of the present invention provide a method, system, and computer program product for allocating storage extents. Extent input/output information pertaining to an extent on a storage device is received, by a computer, where the extant input/output information includes an access rate of data stored on the extent. The computer determines one or more periods of time where the input/output information exceeds a preconfigured threshold. The computer generates one or more of a first policy and a second policy based on the determined one or more periods where the first policy includes allocating the extent to a high performance disk within a tier storage system when data is stored during the determined periods and the second policy includes reallocating the extent from a low performance disk within the tier storage system to a high performance storage device within the tier storage system during the one or more determined periods.

Allocating storage extents in a storage system

Embodiments of the present invention allow a data segment stored in a compressed format to be directly staged into a cache allowing access to the data segment. In operation, a request to access a data segment is received. In response, whether the data segment is stored in a compressed format is determined. If the data segment is stored in the compressed format, the data segment is staged directly into a cache.
