A social networking service encourages users to post content to a communication channel with varying levels of accessibility to other users. Users may select how content will be published and control the accessibility of uploaded content using a privacy setting for each content item that the user posts. The privacy setting defines, or identifies, the set of connections who may view the posted content item. The posted content item is placed in a particular communication channel in the social networking service, such as a newsfeed or stream, where the content item can be viewed by those who are permitted to view it according to its associated privacy setting. Varying granularities of privacy settings provide flexibility for content accessibility on a social networking service.

Selective content accessibility in a social network

User login information submitted as part of an attempt to log into a computer system is evaluated for unauthorized or illegitimate use based on indicators of suspicious behavior. Example indicators of suspicious behavior include whether the login information is known to have been compromised, whether the login attempt originates from a network source or a physical source that has previously originated an attempt to log in using login information known to have been compromised, and whether multiple login attempts using the login information from multiple users has originated from the source. A suspicion index can be calculated based on the presence of the indicators of suspicious behavior. The system can require enhanced authentication based on the measurement of suspicious behavior.

Preventing unauthorized account access using compromised login credentials

Disclosed is a method and system for detecting errors in source code of an application without executing the source code. Embodiments of the disclosed technique include detecting an error generating change at a specific location in source code of an application without executing the source code. The detection includes detecting an error in the changed portion of the source code as well dependencies of the changed portion of the source code. After the error detection, an error message containing information of the error is generated and stored in a storage unit. The information on the error includes (a) an indication of the change in source code, (b) the specific location, or (c) reason for the error. The types of error detected can include (i) a data type mismatch error, (ii) a syntax error, and (iii) other errors such as uninitialized variable access, null value or pointer dereference.

Offline type checking in programming languages

Techniques for handshake-free encrypted communication are described. An apparatus may comprise a reception component and a precomputation component. The reception component may be operative to receive a priming message from a client using a stateless network protocol, to establish a communication channel to the client, and to transmit a response to the priming message over the communication channel to the client. The precomputation component may be operative to determine the response in response to the reception of the priming message from the client. Other embodiments are described and claimed.
