“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


Okay, if a torus with a single patch of empty space on its surface is two holes, then this is three holes. But now I’m confused, because I don’t know if that’s true topologically. Otherwise, it’s just a two-torus with a perforation on its 2-surface.
Edit: I’ve been informed by a topologist friend that this has two holes and that the lip of the mug is just a boundary.


I’m hoping that we can skip spleens.
No. Do cool spleen facts. Link to medical research on the spleen. I want to learn more about the spleen; I want an expleenation.
But I’m hoping Dean Pelton stays a while.
(Also, OP, that is= URL parameter is just there for tracking.)
Mm, yeah, you’re right. I think tomorrow sounds like a good time to start.


We’d ask that you didn’t try. Directing your energy toward improving OSM in your area and moving people away from the corporations kowtowing to Trump and other fascists is what makes an actual difference.


OpenHistoricalMap tracks that sort of thing. OpenStreetMap is strictly for what’s currently (and at least semi-permanently) there. For businesses that just closed, it’s a good idea to put a note saying something like “Formerly Dairy Emporium” (along with potentially, say, when it closed if known). This not only potentially helps confused users, but it also helps other contributors who might try to “correct” what seems like a mistake.
Editing and changing the info is ideal, because it preserves the edit history. A deleted object is a lot harder to find the edit history of.


something something ask me literally anything about using or contributing to OpenStreetMap or about what it is/the state of it. get hyperspecific; see if I give a fuck.
Source: reasonably long-time user and contributor
When you wake up and realize you’ve ruined your life not in a way that’s acute, bombastic, and irreversible but in a way that’s chronic, corrosive, and less reversible by the day.


FYI, you can change what quests appear on StreetComplete (and their priority) at Settings > Quest selection and display order. As for contributing to hiking/biking trails and water sources, what you’re able to do is going to be pretty limited on StreetComplete. StreetComplete is there to fill in some data to existing objects.
That said, if there’s a type of quest that would fit StreetComplete but isn’t on there yet, they welcome requests.
Edit: I see the first part was already addressed in another comment. ^_^
Don’t go talkin’ ‘bout that dang ol’ orgy, man, tell you hwat, dang ol’ g-gross, man.


It’s fine to question it within the thread; the Wikipedia resource is a reference, not Gospel. The problem was that they were a) seemingly just spamming it, b) asserting “fake news”, and c) putting responsibility on OP to “verify” for no real reason.


I believe it was:
I agree that’s approximately what you replied to my comment. (Voyager won’t let me see it for some reason.) You also made two other top-level comments at basically the same time which were, IIRC, “This is fake news”
And yeah, acccessing deleted comments on Lemmy is annoying. I wish the user who posted it could still view it; it’d make appeals easier.


Hi, I’m sorry for the accidental permaban. I meant for it to be two days to get you to stop spamming “fake news” on that post. You can see I undid that when I noticed, which is why I put Rule 0 in the comm to encourage appeals (the “mod is a dumbass” rule).


According to its documentation, the app Go Map!! can pull from “quests” (small questions, like “are this store’s hours still up-to-date”) used by the beginner-friendly Android app StreetComplete.
IIRC it does this via an overlay. Keep in mind that Go Map!! is normally a fairly robust editor and kind of does this as a side hustle.


🎵 Well I’m a peanut bar, and I’m here to say 🎵


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.


Well in that case, it’s cool to see Fairphone using /e/OS!
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.
