NO ROOM FOR BUGS

Summary from the TLDR IT newsletter

Software-correctness tools reduce the space for bugs through three approaches: raising the floor with correct-by-construction features like type systems and memory safety, pushing the walls inward with verification tools like SMT solvers, and detecting remaining bugs through model checking and fuzzing. Tools that rely on separate models risk implementation drift, where the model no longer matches the actual code. Hydro addresses this limitation by running correctness checks directly against deployed code.
