Converting JavaScript into a device-independent representation

A mobile phone, comprising:

• a storage mechanism;
• and
• a processor coupled to the storage mechanism and configured to:
• receive, from a first remote system, a source code, wherein the source code is in an interpretable programming language;
• cache the source code;
• establish a wireless connection with a second remote system;
• transmit, through the wireless connection and to the second remote system, the source code as well as information that identifies the first remote system;
• receive, through the wireless connection from the second remote system, at least one of an intermediate representation of the source code and a machine code representation of the source code, wherein:
• the machine code representation of the source code is specific to a hardware configuration of the mobile phone,
• the second remote system is configured to periodically check the first remote system to determine if the source code has changed,
• the second remote system is configured to acquire the changed source code and generate and cache at least one of an intermediate representation of the changed source code and a machine code representation of the changed source code, and
• the machine code representation of the changed source code is specific to the hardware configuration of the mobile phone;
• close the wireless connection with the second remote system;
• store the intermediate representation of the source code or the machine code representation of the source code;
• establish a subsequent wireless connection with the second remote system;
• receive, through the subsequent wireless connection with the second remote system, the intermediate representation of the changed source code or the machine code representation of the changed source code;
• and
• cache the intermediate representation of the changed source code or the machine code representation of the changed source code on the mobile phone.

A non-transitory computer readable storage medium configured to store instructions that, when executed by a processor included in a computing device, cause the computing device to:

• establish a wireless connection with a mobile phone;
• receive, through the wireless connection and from the mobile phone, a source code as well as information that identifies a first remote system, wherein the source code is in an interpretable programming language and received by the mobile phone from the first remote system, and the mobile phone is configured to cache the source code;
• generate and cache at least one of an intermediate representation of the source code and a machine code representation of the source code, wherein the machine code representation of the source code is specific to a hardware configuration of the mobile phone;
• send, through the wireless connection to the mobile phone, the intermediate representation of the source code or the machine code representation of the source code;
• close the wireless connection to the mobile phone,
• wherein the mobile phone is configured to store the intermediate representation of the source code or the machine code representation of the source code;
• periodically check the first remote system to determine if the source code has changed;
• acquire the changed source code;
• generate and cache at least one of an intermediate representation of the changed source code and a machine code representation of the changed source code;
• establish a subsequent wireless connection with the mobile phone;
• and
• send, through the subsequent wireless connection to the mobile phone, the intermediate representation of the changed source code or the machine code representation of the changed source code, wherein the mobile phone is configured to cache the intermediate representation of the changed source code or the machine code representation of the changed source code.

A device, comprising:

• a communication interface configured to provide communication with an external node;
• and
• a processor coupled to the communication interface and configured to:
• establish a wireless connection with a mobile phone;
• receive, through the wireless connection and from the mobile phone, a source code and information that identifies a first remote system, wherein the source code is in an interpretable programming language and received by the mobile phone from the first remote system, and the mobile phone is configured to cache the source code;
• generate and cache at least one of an intermediate representation of the source code and a machine code representation of the source code, wherein the machine code representation of the source code is specific to a hardware configuration of the mobile phone;
• send, through the wireless connection to the mobile phone, the intermediate representation of the source code or the machine code representation of the source code;
• close the wireless connection to the mobile phone,
• wherein the mobile phone is configured to store the intermediate representation of the source code or the machine code representation of the source code;
• periodically check the first remote system to determine if the source code has changed;
• acquire the changed source code;
• generate and cache at least one of an intermediate representation of the changed source code and a machine code representation of the changed source code;
• establish a subsequent wireless connection with the mobile phone;
• and
• send, through the subsequent wireless connection to the mobile phone, the intermediate representation of the changed source code or the machine code representation of the changed source code, wherein the mobile phone is configured to cache the intermediate representation of the changed source code or the machine code representation of the changed source code.
