Blogging with Version Control An Article by Will Darwin willdarwin.com I’ve been musing for a while now on the way blog posts are typically presented—in reverse chronological order. This format has never truly made sense and does not reflect the way good writing and thinking happens. ...The main issue with the ‘pile’ system is that this post is eventually buried beneath more recent pieces of writing; there is no incentive for revisiting or updating the work. Even worse, if an author does decide to unearth the piece and make some major changes, those who read the original piece are not made aware of these alterations. The sorting order is static. bloggingwritinginformation

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.
