Techniques described herein describe a proxy used in an instant messaging system. The proxy, upon receiving an instant message (IM) from a first mobile device and addressed to a second mobile device, dynamically determines whether, and for how long to store the IM on a local proxy. Otherwise the IM is forwarded to a server.

This disclosure provides techniques for dynamic content caching and retrieval. For example, a computing device includes cache memory dedicated to temporarily caching data of one or more applications of the computing device. The computing device also includes storage memory to store data in response to requests by the applications. The storage memory may also temporarily cache data. Further, the computing device includes system software to represent to the applications of the computing device that the portions of the storage memory utilized to cache content are available to store data of the applications. In addition, the computing device includes application programming interfaces to provide content to a requesting application from a cache of the computing device and/or from a remote content source.

Inline pattern matching and policy enforcement may be implemented by a memory storage device. In an example embodiment, a device-implemented method includes acts of receiving, intercepting, and performing and conditional acts of invoking or permitting. A request from a host to perform a memory access operation is received at a memory storage device. Data flowing between an I/O channel and physical storage of the memory storage device is intercepted. A pattern matching procedure is performed on the data with reference to multiple target patterns in real-time while the data is being intercepted. If a pattern match is detected between the data and a target pattern, a policy enforcement mechanism is invoked. If a pattern match is not detected between the data and the multiple target patterns, the request from the host to perform the memory access operation is permitted.

The described implementations relate to verifiable advertisement (Ad) presentation in a computing realm, such as a web-based computing realm. In one case verifiable advertisement presentation (VAP) tools can receive advertising (Ad) content to be presented on the computing device. The Ad content can include device-specific data that is uniquely associated with the computing device. The Ad content can be presented on the computing device. The VAP tools can validate that the Ad content was presented on the computing device. In some cases, the validation can include performing a validation function on at least one portion of the Ad content. Performing the function can serve to identify whether the presented content matches sent Ad content.

Described is a technology by which files that are hardware protected on a storage device, such as a USB flash drive, are managed on a host, including by integration with an existing file system. Each file maintained on a storage device is associated with a protection attribute that corresponds to that file's device hardware protection level. Requests directed towards accessing metadata or actual file data are processed based upon the protection attribute and a state of authentication, e.g., to allow or deny access, show file icons along with their level of protection, change levels, and so forth. Also described is splitting a file system file table into multiple file tables, one file table for each level of protection. Entries in the split file tables are maintained based on each file's current level; space allocation tracking entries are also maintained to track the space used by other split tables.

A method and a storage device may be provided. The storage device may include physical storage subdivided into a number of regions. The regions may start and end based on logical block addresses specified in a region table. At least one of the regions may be mapped to a logical drive letter. One or more others of the regions may be mapped to a subfolder with respect to the logical drive letter. The storage device may include an access control table. Each entry of the access control table may correspond to a respective region of the physical storage. Each of the entries of the access control table may indicate whether the respective region is protected and whether at least one entity is permitted protected access to the respective region after being successfully authenticated.

A method of managing software issues includes receiving issue data from a remote host, where the issue data is related to an issue associated with a software application installed on the remote host. The method identifies a potential solution for the issue and sends solution data to the remote host, where the solution data is related to the identified potential solution. Feedback data may be received from the remote host, where the feedback data is indicative of a degree to which the identified potential solution was effective in resolving the issue.

Described is a technology by which a single physical storage device such as a USB flash memory device is able to boot different computing devices via corresponding different operating systems. The storage device includes a selection mechanism that determines which virtual disk (corresponding to a LUN) is seen by the host as the currently active LUN having sector 0, and therefore is the boot disk. The selection mechanism also may select which (if any) other LUNs are visible to the host. The selection mechanism and accompanying indicator may be operated when the storage device is disconnected, e.g., via manual switches and/or LEDs, buttons and/or a display (e.g., via internal power). Also described is allowing each LUN to have a user-friendly name.
