Abstract: A block storage service provides block-level storage to a plurality of distinct computing instances for a plurality of distinct users. For each of one or more of the plurality of distinct computing instances, information about data being stored in the block storage service is determined. Based on the information about the data being stored in the block storage service, a block storage transaction enhancement for the data being stored in the block storage service is determined. The block storage service performs the selected block storage transaction enhancement with respect to the data being stored in the block storage service.

Abstract: One or more configuration parameters for an object gateway instance are received at an interface to a provider network, the parameters including an identifier of a first object store of the provider network for which to cache objects in a first object cache of the object gateway instance and an indication of a data transfer mode that controls when objects written to the first object cache are written to the first object store. The one or more configuration parameters are stored in a data store of the provider network and sent to the object gateway instance. A read request that includes the identifier of the first object store and a first object identifier is received from the object gateway instance, and a first object associated with the first object identifier and stored in the first object store is sent to the object gateway instance.

Abstract: A web browser is implemented to receive a document from a server. The document may include one or more embedded Uniform Resource Locator (URL) references. The web browser may display the document on a user interface. A user associated with the web browser may determine one or more of the original embedded URL references should be replaced. In response to user input, the web browser may change at least one of the original embedded URL references to a corresponding replacement embedded URL reference and display the document with the replacement embedded URL reference. The web browser may save an association of the original embedded URL reference with the replacement embedded URL reference and subsequently, when receiving the document with the original embedded URL reference, automatically replace the original embedded URL reference with the corresponding replacement embedded URL reference before displaying the document.

According to one embodiment, a method may include detecting a request to access a given online content source, where the request includes referral information specifying one or more search keywords associated with the given online content source, where the given online content source is one of a plurality of online content sources included within an interest space, and where the interest space is identified dependent upon indications of user navigation activity among the plurality of online content sources. The method may further include extracting the one or more search keywords from the request and creating an association of the one or more search keywords with the interest space.

Abstract: Managing content interest data using peer-to-peer logical mesh networks. Instructions may be processor-executable to implement a given logical node of a logical mesh network that includes a number of such nodes. The given logical node may be configured to store identifying information of its peer nodes. In response to detecting a message-passing event, the given logical node may be configured to generate and convey an outgoing message, which may correspond to respective network-based content and may include indicia of the content, to its peer nodes. The given logical node may not convey the outgoing message to any node that is not a peer. Dependent upon indicia of network-based content included in an incoming message received from a given one of its peer nodes, the given logical node may be further configured to update its identifying information to add or delete a particular node as a peer node.

Abstract: A community search system may utilize the results of previous queries from community members and user feedback associated with those results to provide results for subsequent, similar queries from within the same community. Thus, by modifying and combining query results based, in part, on user feedback regarding previous results for similar queries, the trial and error of the many may improve the results for an individual. Users may be grouped into communities whose members are associated by common interests or characteristics. Feedback from one community member may be used to modify the query results for other community members. By analyzing user feedback with the community regarding query results, negative, incorrect or unnecessary results may be omitted or removed from subsequent results for similar queries.
