Abstract: A method, system, and computer readable medium for managing applications on an application execution system are disclosed. On an application server the number of instances of a first application type that are in a busy state is determined. This determination is performed at each respective time interval in a plurality of time intervals. Then, a first running average for the busy state of the first application type is computed based upon the number of instances of the first application type that are in a busy state, at the application server, at each respective time interval. A removal request is sent when the first running average for the busy state meets a first removal criterion. The removal request is a request to remove the application server from a data structure that specifies which of a plurality of application servers accept service requests for the first application type.

Abstract: A method of providing content, performed by a client system is provided in which execution of a mark-all-read command associated with a specified stream to which a user of the client system has subscribed is detected. The specified stream comprises two or more content feeds, and wherein each content feed comprises a set of content items published by a respective publication source. A time of execution of the mark-all-read command is recorded. There is displayed content items associated with the specified stream in accordance with a criterion that content items having associated timestamps dated prior to the recorded time of execution are displayed in a visually distinctive format from content items having associated timestamps dated after the recorded time of execution. The displaying includes determining which content items associated with the specified stream have associated timestamps dated prior to the recorded time of execution.

Abstract: Systems and methods for determining and displaying a count of unread items in content feeds are provided. In some implementations, a method includes determining a count of unread content items available from a media content source and causing the count to be displayed to the user. In some implementations, the determining includes excluding, from the count, regardless of actual read status, content items available from the media content source in accordance with a subscription timestamp. The subscription timestamp specifies a time when the user subscribed to the media content source.

Abstract: A method of providing content, performed by a client system is provided in which execution of a mark-all-read command associated with a specified stream to which a user of the client system has subscribed is detected. The specified stream comprises two or more content feeds, and wherein each content feed comprises a set of content items published by a respective publication source. A time of execution of the mark-all-read command is recorded. There is displayed content items associated with the specified stream in accordance with a criterion that content items having associated timestamps dated prior to the recorded time of execution are displayed in a visually distinctive format from content items having associated timestamps dated after the recorded time of execution. The displaying includes determining which content items associated with the specified stream have associated timestamps dated prior to the recorded time of execution.

Abstract: A method of providing content includes detecting execution of a mark-all-read command associated with a specified stream. The specified stream includes two or more content feeds, wherein each content feed includes a set of content items published by a respective publication source. The method also includes recording a time of execution of the mark-all-read command and displaying content items associated with the specified stream. The displayed content items have associated timestamps, and content items having associated timestamps dated prior to the recorded time of execution are displayed in a visually distinctive format from content items having associated timestamps dated after the recorded time of execution.

Abstract: An application server maintains a first plurality of applications in non-volatile memory. The application server loads into volatile memory a subset of the first plurality of applications. The subset is a second plurality of applications. The application server receives a request to execute an application that is not currently loaded in volatile memory, and in response performs a set of operations: (1) determining that there is inadequate storage space in volatile memory to store the application; (2) identifying at least one application in the second plurality of applications that is designated as exempt from eviction from volatile memory; (3) selecting from among the second plurality of applications an eviction target, where the selection process excludes the designed applications; (4) evicting from volatile memory the eviction target; and (5) loading and executing the application in response to the received request, and returning a result responsive to the received request.

Abstract: Systems and methods for determining and displaying a count of unread items in content feeds are provided. In some implementations, a method includes determining a count of unread content items available from a media content source and causing the count to be displayed to the user. In some implementations, the determining includes excluding, from the count, regardless of actual read status, content items available from the media content source in accordance with a subscription timestamp. The subscription timestamp specifies a time when the user subscribed to the media content source.

Abstract: A server system subscribes a first user of a first client device, in communication with the server system, to a specified stream of content feeds, where the specified stream of content feeds was defined by a second user at a second client device and comprises one or more other streams of content feeds, a respective stream of the one or more other streams of content feeds was defined by a third user at a third client device and comprises two or more content feeds, and each content feed comprises a set of content items published by a respective publication source. Pursuant to the subscription of the first user to the specified stream of content feeds, the server system sends to the first client device for presentation to the first user content items associated with the specified stream of content feeds.

Abstract: A method quantifies unread content items for a stream subscribed to by a user. The stream includes a time-ordered list of content items from two or more content feeds. Each content feed includes a set of content items published by a respective publication source. The method includes determining a count of content items having an unread status in accordance with read state information stored for the user with respect to the stream, and transmitting the count to a client system for display.

Abstract: At a client device, a user subscribes to a specified stream, where the specified stream includes one or more other streams. A respective stream of the one or more other streams includes two or more content feeds, and each content feed includes a set of content items published by a respective publication source. The client devices presents to the user (e.g., on a display of the client device) content items associated with the specified stream. In some embodiments, streams can be recursively defined to include combinations of other streams, and users who subscribe to a recursively defined stream receive content items from the content feeds associated with that stream.
