Aspects of the disclosure provide for mechanisms for managing containers across operating systems in a computer system. A method of the disclosure includes: causing a first container management agent in a first container to run a user interface in the first container, receiving a user request to create a copy of the first container, creating a second container in view of the first container, receiving, from the user interface running in the first container, a first command to switch from the first container to the second container, and responsive to receiving the first command to switch from the first container to the second container: configuring the second container in view of one or more configurations of the first container, causing a second container management agent in the second container to run the user interface in the second container, and causing execution of the first container to stop.

Managing containers across multiple operating systems

Aspects of the disclosure provide for mechanisms for managing containers across operating systems in a computer system. A method of the disclosure includes: running a first container corresponding to a first operating system, wherein the first container is created in view of a container image; receiving a user request to switch from the first operating system to a second operating system; in response to receiving the user request, switching, by a processing device, from the first container to a second container corresponding to the second operating system, wherein the second container is created in view of the container image, wherein switching from the first container to the second container comprises: configuring the second container in view of a plurality of configurations of the first container; and running the configured second container.

An embodiment relates generally to a method of messaging. The method includes providing a message activation widget on a lock dialog box of a screen saver application and activating the message activation widget. The method also includes displaying a message user interface configured to accept a message and displaying a screen saver image in response to saving an entered message in the message user interface.

Systems, apparatus and methods for a messaging system

Embodiments of the present invention provide a mechanism for an operating system and applications to cooperate in memory management. Applications register with the operating system for cooperative memory management. The operating system monitors the memory and determines a memory 'pressure' related to the amount of demand for the memory. As the memory pressure increases, the operating system provides a memory pressure signal as feedback to the registered applications. The operating system may send this signal to indicate it is about to commence evicting pages from the memory or when it has commenced swapping out application data. In response to the signal, the registered applications may evaluate the memory pressure, determine which data should be freed, if any, and provide this information back to the operating system. The operating system may then free those portions of memory relinquished by the applications. By releasing data the system may thus avoid swapping and increase its performance.
