Abstract: One embodiment receives a request for a screen of a user interface (UI) of a software application from a second computing device, wherein the screen comprises one or more UI components; accesses a set of features of the second computing device; for each UI component contained in the screen, generates first code for rendering and displaying the UI component on the second computing device based on the set of features of the second computing device; and transmits the first code to the second computing device.

Abstract: In particular embodiments, one or more notifications are presented on a screen of a personal computing device while the personal computing device is in a locked state. Entry of one or more user responses may be detected on the personal computing device while still in the locked state. Each user response may be associated with at least one notification. An authorization event associated with the personal computing device may be detected, thereby unlocking the personal computing device. The one or more user responses on the personal computing device may then be presented to the user for confirmation. Once user confirmation is received, confirmed user responses may then be published.

Abstract: In one embodiment, a method includes determining one or more applications on one or more first client computing devices of a first user of a social-networking system; determining one or more second users of the social-networking system that are connected to the first user within the social-networking system; determining one or more applications on one or more second client computing devices of the second users; comparing the applications on the first client computing devices with the applications on the second client computing devices; determining one or more application recommendations for the first user based at least in part on the comparison; and sending the application recommendations to the first user.

Abstract: In one embodiment, receiving, at a first computing device from a second computing device, a request for a view of a user interface of a native application executing on the second computing device, wherein the view includes one or more first user interface components; determining, by the first computing device, a user agent type of the second computing device; selecting, by the first computing device, one or more second user-interface components to be included in the view based on the user agent type of the second computing device; generating, by the first computing device, code implementing a structured document that represents the view, wherein the structured document comprises the one or more first user-interface components and the one or more second user-interface components; and transmitting, from the first computing device to the second computing device, the code.
