@SuricrasiaOnline I want to start using this term for any unexpected and peculiar emergent phenomenon. "Black swan" was originally a financial term but is used in IT for an outage that cannot be anticipated, and thus is difficult to harden against. "Rogin's bear" could be, e.g., when code is compiled and then opened in a binary editor, displaying a Fibonacci progression when a specific language and specific software versions are used.
The Wandering Shop is a Mastodon instance initially geared for the science fiction and fantasy community but open to anyone. We want our 'local' timeline to have the feel of a coffee shop at a good convention: tables full of friendly conversation on a wide variety of topics. We welcome everyone who wants to participate, so long as you're willing to abide by our code of conduct.
