On Design Engineering: I think I might be a design engineer... An Article by Trys Mudford www.trysmudford.com Design engineering is the name for the discipline that finesses the overlap between design and engineering to speed delivery and idea validation. From prototyping to production-ready code, this function fast-tracks design decisions, mitigates risk, and establishes UI code quality. The design engineer’s work encapsulates the systems, workflows, and technology that empower designers and engineers to collaborate most effectively to optimise product development and innovation. — Natalya Shelburne softwareux
Wang tiles Wang tiles (Hao Wang, 1961) are a class of formal systems. They are modelled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them. The basic question about a set of Wang tiles is whether it can tile the plane or not, i.e., whether an entire infinite plane can be filled this way. The next question is whether this can be done in a periodic pattern. In 1966, Wang's student Robert Berger solved the problem in the negative. He proved that no algorithm for the problem can exist, by showing how to translate any Turing machine into a set of Wang tiles that tiles the plane if and only if the Turing machine does not halt. The undecidability of the halting problem then implies the undecidability of Wang's tiling problem.
