This paper will argue that there is no such thing as miscomputation, contrary to the received view in philosophy of computation and (possibly) computer science. There are just hardware problems on the one hand and programming errors on the other, neither of which constitute a distinct kind of computational malfunction. One upshot of this argument is that philosophical accounts of physical computation should not be assessed on whether they can accommodate miscomputation in the abstract, but rather on whether they can make sense of the range of different phenomenona that are commonly (and misleadingly) described as miscomputations
