“Falsehood flies, and truth comes limping after it, so that when men come to be undeceived, it is too late; the jest is over, and the tale hath had its effect: […] like a physician, who hath found out an infallible medicine, after the patient is dead.” —Jonathan Swift

  • Topologically, that part is not a hole. The liquid basin not being a hole is where the joke in the OP originates, even: a standard coffee mug with a basin for coffee and a handle is homeomorphic (topologically equivalent) to a torus (a donut). And that’s because the handle is the hole, not the basin.

    In the case of the OP, ignore the handle for a second just to simplify things. That’s a hollowed-out donut (torus) except that you’ve taken a part of that donut’s surface and cut it out. That area that’s been cut out isn’t topologically a hole; instead, you’ve just created a boundary on the 2-manifold (read: flexible surface).

    Topology has rigorous, algebraic definitions under the hood, but that’s what’s going on in this picture topologically: you’ve taken a donut, glued it to another donut, and cut a “hole” (colloquial usage) in the double-donut’s surface, creating a boundary on the surface.

















  • It reminds me of this conspiracy that was circulating a few months back that Apple Maps had “deleted” cities and places in Lebanon to culturally erase it for Israel’s invasion.

    In reality (which you could see by e.g. looking at Reddit posts from a few years ago), Apple Maps’ coverage of Lebanon was absolute unusable dogshit the entire time. There were complaints about how it wasn’t even usable for basic navigation in Beirut. The city of Tyre (which was misspelled “Tyr”) was still there despite being one of the hardest-hit cities by Israel’s invasion.

    Which was, to be fair, staggeringly incompetent, but it was provably true. Apple Maps’ coverage sucked so badly that, at a surface level, it looked like somebody took an erase tool to a competent map.

    I think a lot of people don’t realize how automated corporate maps applications are. Which can be a weakness for crowd-sourced data like OpenStreetMap when there aren’t enough contributors, but that democratization is also a huge benefit that anyone can see and fix issues. The main parts of Google Maps that aren’t automated are points of interest, and those are kept up-to-date thanks to the network effect where e.g. business owners see value in maintaining their information or users feel like they’re helping out (read: doing free labor for a trillion-dollar corporation).


  • So fwiw, the change was made official and updated in GNIS the day it changed on Google Maps, which uses GNIS behind the scenes. That same day, USGS said the name had taken effect in GNIS but that it was waiting for its maps to visually update.

    I think this is a product of Google’s infrastructure being faster to automatically update with GNIS changes. The fact they didn’t step in to override it already shows that they’re willing to go along with this; I don’t think the fact it changed before USGS adds any significance to that bootlicking.

    That is, I don’t assume Google manually intervened to make this happen faster.

    Still, fuck Google Maps. I’m glad people are waking up to how this level of hegemony over maps gives corporations too much power.
