Systems and methods that may be used in instant messaging (IM) environments to allow users in IM environments to share information and render shared information are described herein. In at least one embodiment, a system can receive an indication to publish a geographical location of a client and based on the indication to publish, a system can provide the geographical location of the client and instruction code for rendering an indication of the geographical location of the client within a map. In some embodiments, the geographical location of the client can be presented to one or more users, or contacts, in instant messaging environments.

Self-described rendering of data

An exemplary data package for a network-based instant messaging system includes descriptive data about a user of the instant messaging system and data indicating a network location of a gadget to render the descriptive data, the location accessible by one or more other users of the instant messaging system. Various other exemplary methods, systems, device, etc., are also disclosed.

A strategy is described for constructing bloom filter information and exception information. The bloom filter information is constructed to express a set of items in a lossy compressed form. The exception information reveals occasions in which the bloom filter information erroneously indicates that a candidate item is a member of the set. The strategy can apply the bloom filter information and the exception information to select a representative device among a group of devices on which a user may maintain simultaneous presence.

Strategies for compressing information using bloom filters

Security provisions are described which determine whether or not executable content is likely to perform undesirable actions. The security provisions assess that an executable content item poses an acceptable risk when it conforms to an allow list of predetermined patterns of permissible behavior. The security provisions find exemplary use in the context of an instant messaging environment, where participants can consume and propagate executable content in the course of conducting a communication session. Supplemental rules are described which prevent malicious code from subverting the allow list design paradigm.

Strategies for ensuring that executable content conforms to predetermined patterns of behavior ('inverse virus checking')

Content synchronization in a file sharing environment is described. A node in a circle share maintains a version vector that represents that node's knowledge of file synchronization events. Version vector data may be transmitted between nodes of the circle share via a presence service in the form of short notification messages. The version vector data is compared to identify one or more nodes to be synchronized. A resource-aware overlay representing the circle share is computed, and is used to initiate communication to determine which of the available nodes with which to synchronize will provide the most synchronization value to other nodes in the circle share.

Content synchronization in a file sharing environment

Various embodiments can utilize a distributed solution for scheduling connections between peers in a file sharing environment. In accordance with at least some embodiments, individual nodes in a peer-to-peer system include scheduling software that enables the nodes to make scheduling decisions with regard to how, when and where connections are made with other peers. Scheduling decisions can be based on a number of different parameters. In at least some embodiments, a synchronization negotiation manager is embodied with logic that drives the negotiation and scheduling process. This logic is represented by an innovative state machine that is designed to implement the negotiation and synchronization process.

A method, medium, and computer-program product is provided for tracking memory-usage characteristics of an application. The invention includes a suite of tools to evaluate memory usage of uninstrumented binaries by tracking memory allocations, deallocations, and in-memory-presence attributes at the module level. Memory-manipulation function calls (not limited to allocations and deallocations) are hijacked to code segments that annotate and log then-current memory characteristics. Processing is reverted back to its from-hijacked position and allowed to continue. In-memory presence of allocated memory and labels for certain points at time are tracked as well. The tracked data is logged so that algorithms can be run to extract desired information, which can be presented in various reports.

The invention includes a suite of tools to evaluate memory usage of uninstrumented binaries by tracking memory allocations, de-allocations, and in-memory-presence attributes at the module level. Memory-manipulation function calls (not limited to allocations and deallocations) are hijacked to code segments that annotate and log then-current memory characteristics. Processing is reverted back to its from-hijacked position and allowed to continue. In-memory presence of allocated memory and labels for certain points at time are tracked as well.
