Abstract: An online marketplace of digital goods is provided. A digital good proposed to be listed in the marketplace is received, where the source code for the received digital good includes scripting language code. The source code of the received digital good is rewritten to include tracking code to track behavior of the received digital good during execution of the re-written digital good, and the rewritten digital good is executed in a browser run by one or more processors of a computer system. One or more processors of the computer system automatically determine, based on evaluation of results of executing the re-written digital good, whether the digital good violates one or more predetermined conditions. Based on the determination of whether the digital good violates one or more of the predetermined conditions, an automatic determination is made whether to list the received digital good in the marketplace.

Abstract: A digital good offered for downloading from a first computing system to a client computing device for execution by a browser executing on the client is identified. The digital good is received at a third computing system, where source code for the received digital good includes scripting language code. The code is re-written to include tracking code to track behavior of the digital good during execution of the digital good, and the re-written digital good is executed in a browser run by the third computing system. Based on evaluation of results of executing the re-written digital good, it is automatically determined, by the third computer system, whether the digital good violates one or more predetermined conditions, and based on the determination of whether the digital good violates a predetermined conditions, it is automatically determined whether to discourage downloading the digital good to, or executing the digital good by, the client.

Abstract: A program binary file is identified as part of a webpage, where the file can be downloaded from the webpage for execution by a client. A browser-executable web application or browser extension that is installed on a client computing device as a consequence of executing the program binary is identified, where source code for the web application or browser extension includes scripting language code. The source code of the web application or browser extension is re-written to include tracking code to track behavior during execution of the re-written web application or browser extension. It is determined whether execution of the re-written web application or browser extension violates one or more predetermined conditions. Then, it is determined whether to discourage downloading the program binary from the webpage to the client computing device or whether to disable execution of the web application or browser extension on the client.

Abstract: A development tool for optimizing a software program is disclosed herein. The tool may be implemented as machine readable instructions, part of a specially configured computer, or part of a practical application of a specialized process. The tool may comprise: an automation rig for executing the program, a capture tool having a plurality of data recorders, an aggregator for generating cluster data based on code block execution patterns, and a code writer for generating optimized binary programs.

Abstract: In one configuration, a program analyzer for comparing a first and second program is disclosed. The analyzer may be stored on tangible computer readable storage media, and configured to be executed by a processor of a computer. Each program may comprise a plurality of blocks, each block comprising a block identifier. The analyzer may comprise a preparation process, a comparison process, a refinement process, a repetition process, and an output process.

Abstract: Systems and methods for profiling an executable include generating differently instrumented versions of a portion of the program code for the executable. References to the portion of the program code may be replaced with references to a control function that conditionally executes the differently instrumented versions. Different profiling modes may be selected at runtime to control which version is executed. Profiling data may also be generated during execution of the program.
