Systems and methods for providing data replication and/or synchronization across multiple processor-based devices. Data objects (e.g., image files, video files, audio files) may exist in a plurality of forms (e.g., original, preview, thumbnail). The systems and methods utilize object device links (ODLs) and needs/has flags which are replicated to multiple processor-based devices to provide partial or full object replication between multiple processor-based devices. Some implementations provide complete replica backups of objects. Some implementations provide temporary protection of original forms of objects, for example, when a user is traveling. Some implementations provide for relaying and shuttling of objects across multiple devices via one or more networks and/or via peer-to-peer wired or wireless communications also allowing for offsite and remote location backup of objects. Some implementations provide support for container and individual object replication policies with inheritance. Some implementations can provide load balancing storage of objects. Some implementations can provide for efficient space management of objects on storage-constrained devices.

Object replication using object device links and flags

A method is provided for network identification based on high entropy data on a network which are not easily guessed or obtained outside the network, which can prevent an attacker from 'spoofing' the network. A component in a client computer connected to a network may obtain over the network a network data block including device identification information of a device controlling the network. Upon parsing the network data block, such high entropy data as unique device identifiers may be obtained from the device identification information. Depending on availability of the unique device identifiers and authentication history of the client computer, different combinations of the unique device identifiers and/or other identification information may be used to generate a unique network identifier such as a network signature. The component may provide the network signature to applications within the client computer.

Secure identification of intranet network

A system and method for facilitating simulation of a computer program. A program representation is generated from a computer program. A simulation of the program is performed. Simulation may include applying heuristics to determine program flow for selected instructions, such as a branch instruction or a loop instruction. Simulation may also include creating imaginary objects as surrogates for real objects, when program code to create real objects is restricted, or fields of the objects are unavailable or uncertain, or for other reasons. Data descriptive of the simulation is inserted into the program representation. A visualizer may retrieve the program representation and generate a visualization that shows sequence flows resulting from the simulation.

Program code simulator

A condition detected by a virtual routine may be treated by setting an error code or raising an exception, depending on circumstances. Enhanced vtable layouts promote availability of both error-ID-based and exception-based virtual routines, while maintaining compatibility. Compilers treat virtual routines based on their circumstances. One enhanced vtable includes error-ID-based routine pointers in a COM-layout-compatible portion and exception-based routine pointers in an extension. For a virtual routine not overridden by a derived class, a compiler generates a direct call. For an object instance of a specific type, the compiler generates a direct exception-based call for the object's routine. For a factory-sourced object's routine, the compiler generates a virtual exception-based call. When the virtual routine belongs to a component having an enhanced vtable, the compiler may generate a virtual call using the exception-based routine pointer. Code wrappers between COM and native format may also be used.

Error-code and exception-based function dispatch tables

Some embodiments of the invention are directed to increasing security and lowering risk of attack in connecting automatically to networks by enabling client devices to verify the identity of the networks by, for example, confirming the identity of networks and network components such as wireless access points. In some embodiments, a client device may maintain a data store of characteristics of a network&#x2014;including, for example, characteristics of a wireless access point or other portion of the network and/or characteristics of a connection previously established with the wireless access point and/or network. Stored characteristics may include characteristics other than those minimally necessary to identify a wireless access point and/or wireless network. The stored characteristics may be compared to known good characteristics of a network (including characteristics of a wireless access point or other portion of the wireless network) prior to connection to the network to determine whether the characteristics match.

History-based downgraded network identification

A network and connection provisioning framework for configuring and provisioning multiple aspects of network connectivity (e.g., multiple networks, media types, and/or connections). The framework may comprise a unified configuration interface that enables an administrator to configure multiple different types of network connectivity. A single configuration file comprising settings for multiple aspects of network connectivity may be generated based on preferences entered by a system administrator, or by exporting current settings from a particular computing device. Global configuration policies or other configuration settings that span multiple types of network connectivity may be also created and stored in one or more configuration files. Stand-alone media managers and/or plug-in modules may implement one or more standardized application programming interface functions so that they may interoperate with the network and connection provisioning framework. The standardized API may be used to ensure that configuration information is handled and stored in a standardized manner by different media managers and/or plug-in modules.

Creating cross-technology configuration settings

Methods and systems which identify and interact with network interfaces based on the network to which they provide access. A computing device operating in accordance with one or more of the principles described herein may examine available network interfaces and identify the network to which the network interfaces provide access, and perform networking tasks on interfaces based on the network identified. For example, a user may instruct a computing device to connect to a specified network, and the computing device will select a particular network interface by which to connect from the one or more available network interfaces that are able to connect to that network. Alternatively, a user may manage policies (e.g., security, connection, and application policies) based on the network to which a network interface provides access and thereby manage a network regardless of which of multiple network interfaces is used to access the network.

Various technologies and techniques are disclosed for using heuristics to determine source code ownership. A request is received to identify at least one owner of a particular source code unit. Initial ownership totals are calculated for the source code unit based upon a code contribution heuristic. The code contribution heuristic counts lines of code that were added and that were modified in the totals for contributing users. The initial ownership totals of the particular source code unit are adjusted based upon at least one other heuristic. The at least one owner of the particular source code unit is then output to an output device. The at least one owner is determined by selecting a contributing user that has a highest ranking total after adjusting the initial ownership totals. For example, there can be a primary owner and a backup owner selected based on the ranking of the ownership totals.

Heuristics for determining source code ownership

A method and user interface for informing a user of the status of a network connection are provided. Conventionally, the 'connected' icon in the system tray only informs the user that the computer is linked to a network medium, such as an Ethernet or wireless access point. This icon does not indicate whether a routable IP address has been obtained. In this invention, an icon is used to inform the user that the network connection is disabled, connecting, connected (routable IP address obtained), or in a warning state. The warning state indicates that a non-routable IP address (e.g. autonet address) has been obtained, which will likely be unsatisfactory to the user. However, when connected to an 802.11 ad-hoc network, or when IP status checking is disabled, a non-routable IP address is deemed acceptable, and thus the 'connected' icon is displayed.

System, method and user interface for network status reporting

A networked computer with a networking framework that can operate in accordance with a standard protocol or may be configured to perform one or more functions that alter or extend processing according to the standard. The framework includes extensibility points and a mechanism to receive plug-ins that may perform extensibility functions. Network profile information indicates configuration of the extensibility points, including specific extensibility functions to be executed at the extensibility points. This information may be used to configure the extensibility points so that, as the computer operates, the extensibility functions are selectively executed instead of or in addition to standard functions.
