A method of preserving file metadata associated with an edited file, performed on a client device, includes storing in a log information denoting a plurality of create, delete, and rename operations on one or more files in a file system, and determining when two or more operations denoted in the log, including an operation involving a first file and another operation involving a second file, comprise an atomic save of a respective file, the first file comprising a first version of the respective file, and the second file comprising a second version of the respective file, the first file and second file each having associated metadata. The method further includes associating a subset of the metadata of the first file with the second file, such that at least one of a globally unique file identifier and file access permissions associated with the first file become associated with the second file.

Preserving file metadata during atomic save operations

Methods and apparatus for scheduling and controlling power management activities are disclosed. An example method includes detecting, by a computing device, playback of video content at a frame rate that is greater than a predetermined threshold frame rate. The example method further includes, in response to the detection of the playback of video content at the frame rate greater than the threshold frame rate, overriding a screen dimming operation of the computing device.

Conditional power management activities

Methods for returning a computing system to a previous state are provided. In one aspect, a method includes loading a second system state of a second operating system partition, and receiving a request to return to a first system state of a first operating system partition while operating in a second system state of the second operating system partition. The method also includes loading the first system state of the first operating system partition. Systems and machine-readable media are also provided.

User initiated data rollback using operating system partitions

Metadata for a set of files in a file system is stored in a client metadata database. In addition, a subset of content for the set of files in the client metadata database is stored in a client content database. The subset of content does not exceed a cache size that is less than a full size of the content in the set of the files. In response to a request, at least a portion of the content that is not already stored in the client content database is retrieved from a server content database, where the server content database is located remotely from the client device.

On demand access to client cached files

A system and machine-implemented method for providing a software update within a network comprising plural computing devices. A subset of the plural computing devices is identified for installation of the software update. The software update is provided to the computing devices within the subset for installation. After providing the software update, a software version or a connectivity status is obtained for at least one of the computing devices within the subset. A determination is made that the software update is invalid based on the obtained software version or connectivity status.

Providing a software update to computing devices on the same network

In some embodiments, a device for network connection selection may include a network connection selector configured to obtain historical connection information related to previous network connections utilized by a device. The historical connection information may include connectivity disruptions indicating whether connectivity was disrupted for one or more network connections that were previously established by the device. The network connection selector may be configured to select a network connection for the device among a plurality of available network connections based on an evaluation of the historical connection information such that the selected network connection substantially maintains connectivity to a network for a future period of time.

System and method for intelligent network connection selection

According to one general aspect, a method may include monitoring, by a computing device, a user's current behavior in regards to the computing device. The method may also include determining whether to place the computing device in a reduced power mode based upon the user's monitored current behavior and based on a history of user habits in regards to one or more computing devices. In various implementations, the method may further include, if it is determined to place the computing device in the reduced power mode, placing the computing device in the reduced power mode.

Heuristics based on backoff for power modes

Methods and apparatus for scheduling and controlling power management activities are disclosed. An example method includes automatically scheduling a wake-up alarm for a computing device and transitioning the computing device from an active power state to a first low power state. The example method also includes, in response to occurrence of the automatically scheduled wake-up alarm, transitioning the computing device from the first low power state to the active power state and transitioning the computing device from the active power state to a second low power state, where the second low power state is a lower power state than the first low power state.

Computing device power state transitions

A method may include operating a device in a first power mode, setting flag(s), each flag representing an executing task, detecting a request to place the device in a second power mode. The second power mode consumes less system resources than the first power mode, and delaying the transition to the second power mode by placing the device in a third power mode that consumes less system resources than the first power mode but more than the second power mode. While in the third power mode, the method may include estimating an amount of system resources required for each of the task(s), determining if the total estimated amount of system resources to complete each of the task(s) exceeds one or more system resource threshold values, and if the estimated total amount of system resources exceeds the one or more system resource threshold values, ceasing execution of the task(s).

Delaying the initiation of transitioning to a lower power mode by placing a computer system into an intermediate power mode between a normal power mode and the lower power mode

A computer-implemented network node selection method includes identifying a plurality of operable wireless network access points within communication range of a wireless device connected to a mobile computer; identifying which of the operable wireless network access points is arranged to trap a requesting device in a proxy; and affecting a manner in which prospective wireless network access points are presented to a user of the mobile computer based on the identifying of which of the operable wireless network access points is arranged to trap a requesting party in a proxy.

Identifying trapping access points

According to another general aspect, a method for displaying the system resource usage of a computer may include identifying the number of open tabs in one or more tabbed based browsers running on the computer. The method may include determining the system resource usage of each tab. The method may further include displaying the system resource usage of each tab in a system resource meter.

Power monitoring and control in cloud based computer

According to one general aspect, a method of regulating the system resource consumption of an apparatus may include monitoring one or more system resources of the apparatus. The method may also include receiving a request to display, via the apparatus, a requested multi-element document. The method may include retrieving by the apparatus, at least in part, the requested multi-element document. The method may include dynamically editing the requested multi-element document based, at least in part, upon the monitored system resources. The method may also include displaying the dynamically edited multi-element document.

Power metering and control in cloud based computer

According to one general aspect, a method may include operating a computing device in a first power mode. The method may also include executing, by a processor of the computing device, at least one non-interactive task. The method may also include detecting, by a processor of the computing device, a request to place the computing device in a second power mode, wherein the second power mode consumes less system resources than the first power mode. The method may further include delaying the transition of the computing device to the second power mode until either the completion of the non-interactive task or an overriding triggering event.
