As one of the examples, one of the main features is that the setup is small enough that it can live with the camera full-time, and carried around by the user. The legs fold into a very compact size that fit within the footprint of the camera, used for any type camera, e. g. compact point-and-shoot camera, camera phone, or SLR camera. The tripod can then live unnoticed on the bottom of the camera, until a shot requiring a tripod is needed. Then, the legs can be deployed to act as a firm stand. Another one of the main features of this tripod is that all the legs do not share a common end-point or pivot-point. This allows the legs to form a very wide stable platform, even when they are short. In general, for N legs, some legs may have common end-points or pivot-points, but not for all N legs. (N is a positive integer, greater or equal to 3. ) This invention can be applied to any camera (e. g.

Architecture for synchronizing data between business applications according to a multi-master arrangement. Changes to business entities can be snapshot changes, delta changes, and long-running process changes, the latter which can be derived from the first two. The architecture includes automatic error retry logic, such that when synchronization errors occur, the logic can be replayed to resolve the errors, when conditions have changed where the errors can be resolved. This also applies to when one error causes a cascading set of errors. By replaying one error, the other errors will be resolved. Backup and restore of a participating application is also provided such that a new data change in a non-backup-restored application will automatically be synchronized to the recently-restored system.

A service broker for asynchronous execution of software. The broker functions include dynamically loading working modules from a specified directory, publishing the working module commands, receiving service requests from clients, and upon successful authentication and authorization, dispatching the requests to module command queues for scheduling and execution. The modules are invoked in separate domains so that management functions can control the modules independently. A management application facilitates interactive user scheduling of the actions being invoked. This can also be accomplished automatically according to business rules, for example. The management application also facilitates checking the progress on an action that is occurring, displaying errors that occur during the command execution, results of an action can also be displayed, and scheduling of requests.

Anchor tree cross-merge within a distributed storage system. A computer system identifies a data structure that includes (i) a root anchor tree and (ii) an ordered set of anchor trees that are ordered based on their creation, such that a last anchor tree of the ordered set of anchor trees is most-recently created. The data structure stores index data for a set of objects stored in a non-volatile storage. The computer system creates a new anchor tree in the ordered set of anchor trees. The computer system identifies, from a set of delta tables, index data representing one or more objects that are stored on the non-volatile storage. The computer system merges the index data representing the one or more objects into the new anchor tree.

A distributed storage system includes table controllers collectively storing partitions of a logical table having multiple rows. For each of the partitions, a corresponding table controller stores a subset of the rows of the logical table across individual pages. A management controller updates a schema of the logical table from a first to a second schema definition by, for each of the partitions, sending an update command indicating the second schema definition to the corresponding table controller. The first table controller corresponds to a first partition that includes a first subset of the rows. The first table controller, prior to receiving the update command, includes an identifier of the first schema definition within each page of data for the first subset. Subsequent to receiving the update command, the first table controller, when writing each new page of data for the first subset, includes an identifier of the second schema definition.

A distributed storage system includes non-volatile storage storing portions of a first object. The first object encompasses data having a first range of addresses and each portion includes data for a respective range of addresses that is a proper subset of the first range. A first data structure stores, for each portion, data indicating the respective range of addresses and a pointer to where the portion is stored. The first data structure includes a root tree and a set of trees ordered by creation data such that a last tree is most-recently created. The non-volatile storage stores received write data and a write buffer stores index data pointing to storage locations of the received write data. An index management system stores the index data from the write buffer into the last tree and, if the ordered set is empty, creates a tree in the ordered set before the storing.

Embodiments provide a method to collect aggregate information or usage data quickly and efficiently with minimal lag. Additionally, the system can use this aggregate information internally for improved load balancing, better data placement, optimization, and enhanced debugging. The system can quickly look at aggregate information across a huge amount of data and drill down cheaply because the aggregate information is generated using existing processes. Aggregated statistics storage and collection may be built on top of an LSM tree used to store a persistent index for a cloud storage system. The statistics may also represent the result of an operation (e.g., max, min, sum, average) on selected parameter(s) or attribute(s) of stored data. Aggregate statistics values may be efficiently maintained during index merge and garbage collection processes or any other index management. As delta LSM trees are merged into a base LSM tree, the aggregates are updated in delta fashion.
