Abstract: Allocating free space in a database table. Statistics associated with records in a database are received, including an average record byte size for records stored in the database table. A primary free space byte size for record updates is determined, including comparing a preliminary free space byte size to the average record byte size and a byte size of a record subjected to a database operation. Based on the primary free space byte size, free space at the page level of the database table is allocated.

Abstract: Embodiments for server port virtualization for guest logical unit number (LUN) masking in a host direct attach configuration using a storage adapter in a computing environment by a processor. An F switch port is simulated by an N storage port to enable either N-port virtualization (NPV) or N-port identification (ID) virtualization (NPIV) in the host direct attach configuration by directly attaching the N server port to the N storage port. A domain name system (DNS) operation is performed to cause each virtualized N-port ID to be mapped to fiber channel (FC) IDs in domain format of domain, area, port.

Abstract: The system includes a plurality of storage volumes, a data synchronization module, a space-efficient storage module, and a heat data module. A second storage volume of the plurality of storage volumes includes a backup storage location for a first storage volume. The data synchronization module, coupled to the first storage volume and the second storage volume, provides a backup by synchronizing information from the first storage volume to the second storage volume during a synchronization event. The information includes data chunks, heat map data, and first metadata. The space-efficient storage module receives the information from the data synchronization module and allocates the information to the second storage volume in accordance with a space-efficient storage model. The heat data module reads the first metadata and the heat map data and adjusts a location of the data chunks in the second storage volume based on the heat map data.

Abstract: A method of measuring the distance of two points of an object by processing the image of the object taken from the mobile phone. The image taken by the mobile phone should contain the object and a piece of a rectangular paper marked with a point on each corner. For example, the object (e.g., a human foot) stands on a piece of the rectangular paper which has a mark on each corner. The image taken by a mobile phone should contain the foot and at least three of the four marks. Likewise, a human standing against the wall aside with the marked paper and a hand pressing on the marked paper are all applicable to the method of measuring any two points in the image of the. The resulted distance of any two points can be used to obtain a correct size of foot or the like.

Abstract: An approach for index B-tree page creation associated with linear sequential insertions in database management systems (DBMS). A linear pre-splitter receives a current index leaf page for linear sequential insertion. The linear pre-splitter asynchronously creates index leaf pages where the current index leaf page is in a predetermined position at least one page away from a last index leaf page. The linear pre-splitter updates index leaf page position identifiers associated with the index leaf pages where the index leaf page position identifiers link the index leaf pages and the last index leaf page and the linear pre-splitter inserts index leaf page identifiers and index key metadata associated with each of the index leaf pages into index non-leaf pages.

Abstract: A structural improvement of a liquid level sensor includes a pair of terminals, a body, and a reed switch. Each of the terminals has a clamping end, a guiding and connecting end, an extending portion, and a welding end. The body covers outer sides of extending portions. The pair of terminals are disposed at an interval inside the body. The body has a notch and a counterbore. The reed switch is clamped on the clamping ends and located at the notch. The clamping ends are respectively disposed on two sides of the notch and protrude from the body. The welding ends are exposed in the counterbore. The guiding and connecting ends extend outward from a side of the body. In this way, positioning of a reed switch is more accurate, production efficiency can be improved, and manufacturing and assembly costs can be lowered.
