Markup language documents including server side scripting code using PHP syntax are executed efficiently in response to requests received by a server. The processing of the markup language document results in generation of a transformed markup language document that is returned in response to the request. The server side script code is input to a compiler that generates C++ code (or code in any object-based language based on C language) implementing the functionality of the server side script code. The C++ code is compiled to generated object code which is executed in order to process the markup language document. The generated C++ code includes functionality supported by PHP language including redeclaration of functions, dynamic variables, global variables, and the like. The generated C++ code invokes memory allocation code that allocates and deallocates objects obtained by instantiating the generated C++ classes.

High performance PHP

In one embodiment, the first processors of a mobile device determine an operating condition of the mobile device. These operating conditions are based on a current velocity of the mobile device, and the current time of day. If the operating conditions satisfy an operating criteria for the mobile device, the first processors send a message to second processors of the mobile device, causing one or more of the second processors to wake up from a sleeping state to an active state.

Dynamic duty-cycling of processor of mobile device based on operating condition of mobile device

In one embodiment, a mobile computing device has a first processor and a second processor. The mobile device determines an operating condition of the mobile device, the operating condition being based on at least the current time of day, a current activity of a user associated with the mobile device, or a current proximity of the mobile device to a place connected to the user of the mobile device through an on-line social network. If the operating conditions of the mobile device are satisfied, the first processor of the mobile device sends a message to the second processor of the mobile device, the message causing the second processor to transition from a sleep state to an active state.

Substantially continuous location logging for geographic-positioning capable devices

In one embodiment, a geographic-positioning component records a first location of a mobile device. The geographic-positioning component determines on a periodic basis a current location of the mobile device. The geographic-positioning component determines whether the current location is outside a geographic region defined at least in part by the first location and a radius, the radius being adjusted from a pre-determined value based on a detected velocity of the mobile device; time of day information; a battery level of the mobile device; or an error of the first location measurement or the current location measurement. If the current location is outside the geographic region, the geographic-positioning component causes a client application of the mobile device to send the current location to a remote server.

In one embodiment, a method includes recording a first location of a mobile device; determining, by a geographic-positioning component of the mobile device, on a periodic basis, a trajectory of the mobile device, wherein the trajectory is calculated based on present and past user locations; determining, by the geographic-positioning component, whether the trajectory is outside a geographic region defined at least in part by the first location; and if the trajectory is outside the geographic region, then transmitting, by the processors of the geographic-positioning component, a message to one or more other processors of the mobile device, the message causing one or more of the other processors to transition from a sleep state to an active state.
