Abstract: Techniques described herein are directed to intelligently identifying items for resale based on digital records of past purchases. A computing system of a payment processing service can analyze digital record(s) of a user that are representative of previous purchase(s) of the user. Based at least partly on analyzing the digital record(s), an item previously purchased by the user can be identified as a candidate for resale to another user. The computing system can monitor marketplace(s), and can determine, based at least partly on monitoring the marketplace(s), item information for the item. The computing system can create, based at least partly on the item information, a listing for an ecommerce channel that enables the user to sell the item. The listing can include an actuation mechanism that enables the other user to purchase the item, a transaction for which can be processed by the payment processing service.

Abstract: A layout manager can generate a layout for displaying a plurality of content units in a display area using a layout strategy, with the layout strategy specifying a layout design rule. The generated layout can indicate a position in the display area for the plurality of content units. In some embodiments, the design rule(s) may in effect “codify” traditional graphic design principles. When the layout is generated, the content units can be placed into a display area of a page and then the layout can be checked against at least one design rule and the layout adjusted as needed to meet the design rule. The system can comprise a user interface module that renders the content units in the display area using the generated layout. In some embodiments, content units are placed into a layout on a one-by-one basis according to priority, available display space, and one or more design rules.

Abstract: A layout can identify placement of a plurality of content units of a document across one or more pages with each page representing a display area for displaying the content of the document. A scrollbar definition can be generated so as to identify a plurality of equally-sized segments of a scrollbar track, with each segment corresponding to a respective one of the pages of the document. The definition can identify a scrollbar thumb having a body that fills a segment. A scrollbar can be rendered based on the definition. The scrollbar definition can be updated to identify a different number of segments of the scrollbar based on a new number of pages in a new layout generated in response to a change in the size of the display area.

Abstract: Various embodiments of methods and apparatus for adaptive content authoring are disclosed. A dimensionally-linked authoring interface comprising a dimension control for associating values of a dimension to frames is displayed. A plurality of frames and input associating each of the plurality of frames to a respective value of the dimension are received. A data structure comprising the plurality of frames and associations between the frames and the respective values of the dimension is generated.
