Abstract: Objects stored in a zip archive may be extracted in random-access fashion (without involving other objects stored in the zip archive) using the addresses of the objects stored in the central directory of the zip archive. However, zip archives often provide insufficient information to enable random access to the data within an object. This capability may be provided by segmenting the object into sections of a section size, and including in the zip archive a block table specifying, for respective sections, the block size of the corresponding block. A zip archive extractor may achieve random access to the object by using the block table to computing the addresses of blocks comprising the selected portion and extracting only those blocks. Backwards compatibility of the zip archive with other zip archive extractors may be preserved by including the block table within a zip extension of the central directory of the zip archive.

Abstract: Techniques to generate mass push notifications are described. In one embodiment, for example, an apparatus may comprise a submission component, a query component, a delivery component, and a record update component. The submission component may be operative to receive a message bundle, the message bundle comprising a message and a query. The query component may be operative to compare the query to a plurality of recipient records to determine a plurality of recipient records matching the query, each of the plurality of recipient records corresponding to a particular installation of a particular application onto a particular device. The delivery component may be operative to broadcast the message to a plurality of installed applications corresponding to the plurality of recipients records matching the query. Other embodiments are described and claimed.
