Very blurry indeed. See for example, "Predictable Programs in Barcodes": http://repository.upenn.edu/cis_papers/200/ http://repository.upenn.edu/cis_papers/20

Very blurry indeed. See for example, "Predictable Programs in Barcodes": http://repository.upenn.edu/cis_papers/200/ http://repository.upenn.edu/cis_papers/200/ From the abstract: "...In particular, we consider programs for microwave ovens, which provide a basic open API for controlling cooking times..." The authors were only able to _simulate_ a microwave oven, presumably because the software on real microwave ovens is closed. A reasonable argument could be made that the proprietary nature of microwave oven software has limited innovation in this market.
