    • Methods and apparatus, including computer systems and program products, that relate to diversification of computer code. The methods feature a machine-implemented method that includes receiving input computer code, and automatically generating multiple versions of diversified computer code, where each version of the diversified computer code is distinct from but functionally equivalent to the input computer code. The input computer code can include source code or binary code and automatically generating multiple versions of diversified computer code can include automatically generating multiple versions of diversified source and/or binary code. Automatically generating diversified computer code can include applying multiple diversification operations.

    • Methods and apparatuses enable brokering the execution of an application. Rather than setting up a complete application execution environment including hardware and software, an execution broker enables execution of an application in a system that is generated or made available in response to a request to execute the application. Some or all components of the hardware and/or software can be virtualized through resources available in one or more backend systems. The request may include a configuration description of a hardware platform and a software environment on which to execute the application. In one embodiment, the configuration of the hardware and/or the software is derived (e.g., based on minimum system requirements and/or client preferences). In response to receiving the request, a hardware platform and a software environment based on the configuration description are generated, to generate the application execution environment for the requested application.

    • A apparatus and apparatus for compensating for video insertion loss due to transmission over long twisted pair cable lines is presented. Transmission of video over twisted pair cable is advantageous because of its superior cost advantage over coaxial cable. However, twisted pair cables have significant loss characteristics at the higher frequencies (i.e., broadband) compared to coaxial cables. At a transmitter station, the video signal is amplified in the high frequency region for possible skin effect losses thereby brute forcing the high frequency components to the receiving station. At the receiver station, the video signal is further compensated for diffusion line and skin effect losses. The total skin effect compensation applied in both the transmitter and receiver stations is such that the square root of frequency characteristics of skin effect losses is compensated for. Thus, at the receiving station, the high frequency compensation added at the transmitter to brute force the high frequency components to the receiving station may be removed if found excessive. Additionally, compensation is included to adjust for skew that may occur because of irregularities between the various twisted pairs used to transmit the individual video components. Non-minimum phase type filters are used to inject delay into the faster arriving signals so that they may coincide in phase with later arriving signals resulting in a true reproduction of the video.
