A collaborative development service manages a document that can be shared among multiple users. If multiple users are editing the document, the edits may need to have operational transformation rules applied thereon. The collaborative development service provides operational transformation rules to users of mobile devices that do not have copies of the operational transformation rules stored on their devices. When a change to the document is received by the collaborative development service, it is determined that a first user device has operational transformation capability. In response to determining that the first user device has operational transformation capability, the change is transmitted to the first user. The collaborative development service determines that a second user device does not have operational transformation capability and applies an operational transformation to the change to generate a transformed change. The transformed change is transmitted to the second user device.

Systems and methods for collaborative document editing

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for delaying code parsing. In one aspect, a method includes receiving a resource that includes markup language code and executable code embedded within the markup language code, invoking the markup language code without parsing the executable code, extracting the executable code from within the markup language code, and invoking the executable code.

Delayed code parsing for reduced startup latency

A request for a document from a mobile device via a network is received. In response to the request, within the document a non-textual document element unrecognizable to the mobile device is identified. Within the document, at a first location associated with the non-textual document element, a start marker comprising a first code selected from a predetermined Unicode range is inserted. Within the document, at a second location associated with the non-textual document element, an end marker comprising a second code selected from the predetermined Unicode range is inserted. The second code has a predetermined relationship to the first code. The document is transmitted to the mobile device via the network.

System and method for using pre-defined character ranges to denote document features

A system and method for viewing content on a mobile device may include outputting, at a display coupled to a mobile computing device, content viewable at the display, and receiving a first gesture indicative of scroll input having a first velocity. The content may be scrolled at a first effective scroll rate based on the first velocity. A size of the content may be altered by a first zoom factor that is based on the first effective scroll rate.

System and method for viewing content

Techniques are described herein that provide for inter-domain communications with one or more shared worker applications. A parent web application associated with a first domain may create a child web application associated with a second domain different than the first domain. The child web application may determine whether a shared worker associated with the second domain is operating. The shared worker acquires information associated with the second domain in response to one or more requests, and stores acquired information associated with the second domain in a memory of the local computing device. The parent web application may request, via the child web application, information associated with the second domain from the shared worker. In response to the request, the parent web application may receive, from the shared worker, information associated with the second domain stored in the memory of the local computing device.

Cross-domain communications with a shared worker application

A request to update a list of conversations is sent to a server. At least a portion of each conversation in the list of conversations is stored on the client. A plurality of updates is received form the server. The plurality of updates includes messages corresponding to respective conversations in the list of conversations.

Mechanism for message prefetching in an intermittently connected offline-capable mobile web application

Apparent performance delays in a computer application are reduced by scheduling garbage collection during periods when a user cannot modify program data within the application. Garbage collection may be initiated in response to detecting a user interface event that prevents user modification of program data being processed by the computer application. Systems and methods herein reduce the appearance of performance delays associated with garbage collection.

Systems and methods for minimizing the effects of garbage collection

In one example, a method includes outputting, at a first location of a presence-sensitive display of a computing device, a first graphical object and receiving an indication of a first touch gesture detected at a second location of the presence-sensitive display. The method may further include, in response to receiving the indication of the first touch gesture, outputting, at the second location, a second graphical object and receiving an indication of a second touch gesture originating within a predetermined distance of the second location and moving towards the first location. The method may further include outputting movement of the second graphical object into contact with the first graphical object. The method may also include, in response to outputting movement of the second graphical object into contact with the first graphical object, outputting at a third location, the first graphical object that is a determined distance away from the first location.

Visual object manipulation

Techniques are described herein that provide a web application that incorporates one or more shared worker applications. In one example, a shared worker application as described herein may receive a first request for first information for a first web application, acquire the first information in response to the request, and store at least a portion of the first information in a memory of a local communications device. The shared worker may further receive a second request for second information for a second web application. The shared worker may determine whether at least a portion of the first information stored in the memory of the local communications device will satisfy the second request for the second information. The shared worker may provide, from the local memory to the second web application, at least the portion of the first information in response to the second request.

Shared worker application

A system and method for suggesting love interests and friendships based on inferred information to users within a social network is disclosed. Data is retrieved from a database. The database includes data from users that achieved relationships. The data also includes a list of each user's connections, the user's activities on the social network and the user's interests. The data is input into a network and the network is trained to predict a likelihood of a successful connection. Data from unconnected users is retrieved and put into the trained network to predict a possible relationship. A connection suggestion is sent to the two unconnected users.

Disclosed are systems and methods for authenticating web users. In one embodiment, a method includes sending the destination web page to the parent frame of the web browser, where the destination web page when processed by the web browser is operable to perform operations, including determining if the web user is authenticated with the content provider and generating a child frame associated with the parent frame if the web user is not authenticated with the content provider. The destination web page is operable to perform further operations, including requesting, by the child frame, an authentication web page from an authorization provider, receiving, by the child frame, the authentication data from the authorization provider, and receiving, by the parent frame, the authentication data.

A system and method for viewing content on a mobile device may include outputting, at a display coupled to a mobile computing device, content viewable at the display, and receiving a first gesture indicative of scroll input having a first velocity. The content may be scrolled at a first effective scroll rate based on the first velocity. A size of the content may be altered by a first zoom factor that is based on the first effective scroll rate. A second gesture indicative of scroll input may be received while the content has a residual zoom factor, the second gesture having a second velocity. The content may be scrolled at a second effective scroll rate based on the second velocity and the residual zoom factor. A size of the content may be altered by a second zoom factor that is based on the second effective scroll rate.

Disclosed are systems and methods for redirecting a request for a non-canonical web page. In one embodiment, a method includes receiving a request, from a client, for an alias Uniform Resource Locator ('URL') at a web server, where an address for the alias URL is different than an address for a canonical URL, where the alias URL and the canonical URL are associated with the same web resources. The method further includes sending a redirect to the client to request the canonical URL, and sending one or more instructions to the client to request the canonical URL for a subsequent request for the alias URL.
