Abstract: Architecture for handling large data selections with small and substantially constant memory footprints. The architecture facilitates the creation of sets of data objects (e.g., rows) of a data source based on selection of the data objects. The set structures can be defined according to a range (span) of data objects selected and a pattern of the objects selected. These set structures are then saved in memory, rather than the data objects, to provide optimized memory usage. In a database implementation, the solution stores the set representation (the structure) in nearly a constant amount of memory, regardless of the number of rows in the grid, and regardless of the number of rows selected. Memory usage can be proportional to the number of discontinuous spans of rows selected by the user. Structures in memory can be consolidated, replaced, or eliminated dynamically as the user changes row selections and pattern criteria.

Abstract: A social network system (or other type of hosting system) is described herein which allows different types of applications to interact with the common resources of the system via respective application-specific channels. Through an application-specific channel, a user may obtain a filtered set of content items (e.g., posts) and notifications that pertain to a particular application with which the user is currently interacting. But the user may also obtain items and notifications that do not necessarily have an affiliation with the particular application. The social network system may maintain a single identity for each user across all application channels hosted by the system.

Abstract: A processing device may include a WYSIWYG tool for designing two-dimensional visual layouts. The processing device may display a visual layout including a first object component and a second object component. The first object component, or an object subcomponent thereof, may be moved or resized, or an object subcomponent of the second object component may be moved or resized. When an edge of the first object component or an edge of the object subcomponent, thereof, is within a snapping distance of an edge of the object subcomponent of the second object component, the processing device may attempt to align the edges and may display an indicator indicating alignment of the edges. The first object component or the object subcomponent, thereof, may be drawn to an aligned position with the object subcomponent of the second object component while the aligned edges are within the snapping distance.
