摘要： Methods and apparatus for implementing modes of operation of computing device are disclosed. An example apparatus includes a mode-selection input device having a first state and a second state. The example apparatus also includes firmware operably coupled with the mode-selection input device. In the example apparatus, when the mode-selection input device is in the first state, the firmware is configured to cause the computing device to operate in a first mode of operation, a user mode. In the example apparatus, when the mode-selection input device is in the second state, the firmware is configured to cause the computing device to operate in second mode of operation, a developer mode.

摘要： One embodiment provides a system that facilitates the execution of a web application. During operation, the system allocates a storage space on one or more storage devices for use by the web application. Next, the system creates, for the web application, a private filesystem comprising a private root directory within the storage space. Finally, the system enables access to the private filesystem for the web application through the private root directory in a manner that does not allow access to a host filesystem associated with the one or more storage devices from the web application.

摘要： Some embodiments of the present invention provide a system that renders graphics in a computing system that includes a plugin associated with a web browser in the computing system and a web application configured to execute in the web browser. During operation, the web application specifies a graphics model and provides the graphics model to the plugin. Next, the plugin generates a graphics-processing unit (GPU) command stream from the graphics model. Finally, the plugin sends the GPU command stream to a GPU of the computing system, which renders an image corresponding to the graphics model.

摘要： A system that validates a native code module. During operation, the system receives a native code module comprised of untrusted native program code. The system validates the native code module by: (1) determining that code in the native code module does not include any restricted instructions and/or does not access restricted features of a computing device; and (2) determining that the instructions in the native code module are aligned along byte boundaries such that a specified set of byte boundaries always contain a valid instruction and control flow instructions have valid targets. The system allows successfully-validated native code modules to execute, and rejects native code modules that fail validation. By validating the native code module, the system facilitates safely executing the native code module in the secure runtime environment on the computing device, thereby achieving native code performance for untrusted program binaries without significant risk of unwanted side effects.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for preserving code safety of application code that is received in a portable, instruction-set-neutral format. One aspect of the subject matter described in this specification can be embodied in methods that include the actions of receiving a portable code file that is implemented in an instruction-set-neutral and source code independent format; translating the portable code file into native object code for execution on a particular instruction set architecture; generating a native executable for the particular instruction set architecture using the native object code; and validation the native executable using a trusted validator prior to execution of the native executable.

摘要： One embodiment provides a system that facilitates the execution of a web application. During operation, the system loads a native code module that includes a scenegraph renderer into a secure runtime environment. Next, the system uses the scenegraph renderer to create a scenegraph from a graphics model associated with the web application and generate a set of rendering commands from the scenegraph. The system then writes the rendering commands to a command buffer and reads the rendering commands from the command buffer. Finally, the system uses the rendering commands to render, for the web application, an image corresponding to the graphics model by executing the rendering commands using a graphics-processing unit (GPU).
