Aspects of the invention include receiving, by a processor, source code for a software program written in a first programming language. The received source code is converted into abstracted source code that is in a generic format that is different than a format of the first programming language. The abstracted source code is compared to known source code patterns. Based on determining that at least a subset of the abstracted source code matches a pattern in the known source code patterns, sending an alert to the user indicating that the received source code matches the pattern.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving, by one or more non-real-time processors, data defining a light illumination pattern for a robotic device. Generating, by the one or more non-real-time processors and based on the data, a spline that represents the light illumination pattern, where a knot vector of the spline defines a timing profile of the light illumination pattern. Providing the spline to one or more real-time processors of the robotic system. Calculating, by the one or more real-time processors, an illumination value from the spline at each of a plurality of time steps. Controlling, by the one or more real-time processors, illumination of a lighting display of the robotic system in accordance with the illumination value of the spline at each respective time step.

Code search is used to support various features. Code segments may be indexed using a code structure representation of the code segment. Code segments may be compared for similarity to identify a match with an input code segment using a comparison of logic trees generated for the input code segment and a stored code segment in an entry with a matching index value.

A method, system, and software for adding to, extending or otherwise modifying a pre-existing computer program, written in a scripting language, with a new source code, written in a scripting language, without the need to sham underlying source code of the pre-existing computer program or the newly modified source code.

A process includes receiving a table data set that represents mappings between a plurality of operand patterns indicating types of operands possibly included in a first instruction used in a first assembly language and a plurality of second instructions used in a second assembly language or a machine language corresponding to the second assembly language. The table data set maps two or more of the second instructions to each of the operand patterns. The process also includes generating, based on the table data set, a translation program used to translate first code written in the first assembly language into second code written in the second assembly language or the machine language. The translation program defines a process of determining an operand pattern of an instruction included in the first code and outputting two or more instructions of the second code according to the determined operand pattern.
