Cyberspace as a global dump If we think that cyberspace is a public space, then let's think of the oceans. They used to be as much of a world resource as anybody could think of but didn't belong to anybody. So everybody put their garbage into them. The potential of cyberspace as a global dump is quite substantial. Ursula M. Franklin, Every Tool Shapes the Task naturetrash
The Poop Press Project (In the run-up to the law, I myself had undertaken the “Poop Press Project,” which had entailed fixing a star-shaped cookie mold to the end of a stick to transform the noisome waste into street art, an attempt only intermittently effective.)

The mirror-image economy When we enter the world of refuse and waste, we cross over into a mirror-image economy. In the "normal" world, we pay to acquire things; on the other side of the looking glass, we pay to get rid of them. Junk isn't merely worthless; it has negative value. A chemical engineer once told me about a recent improvement in a manufacturing process; by fine-tuning a chemical synthesis he had increased the yield of a certain commodity from 98 percent to 99 percent. I congratulated him, but I couldn't help remarking that this seemed like a rather paltry improvement. "Ah, you miss the important point," he said. "The amount of waste goes from 2 percent down to 1 percent. It's cut in half. We save tremendously on disposal costs."

NIMBY, BANANA, NOPE Waste-disposal facilities of all kinds—landfills, incinerators, even transfer stations—are sure bets for generating the NIMBY response: not in my backyard. In its most cynical form, NIMBY is the attitude of citizens who acknowledge the need for a facility, somewhere, but who oppose a plan for building it simply because the selected site is too close to their own property. But opposition to landfills and many other kinds of development goes well beyond cynical NIMBY. Another catch phrase for this phenomenon is BANANA: build absolutely nothing anywhere near anybody. Or else it's NOPE: not on planet earth. Brian Hayes, Infrastructure: A Guide to the Industrial Landscape urbanismcommunitytrash
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.
