10:16:48 <fizzie> Heh, that's odd. There's this monitor, even if it's not connected to power at all (all outlets here have physical power switches in them) the computer says it's connected, and can tell the make, model and supported resolutions. I guess it gets enough juice over HDMI to run that much of the logic, and uses the real power supply just to drive the actual display part of it.

13:14:11 <sknebel> basic implementation of DCC is just an I2C memory chip connected to power and I2C line on the connector, doesnt need any connection to the other electronics in the monitor
13:14:52 <sknebel> not sure if mandated, but certainly intended to work that way
13:22:07 <fizzie> I guess it makes sense. Slightly a shame, though: I was hoping I'd get a monitor hotplug event from turning that thing on/off, but of course it just appears connected all the time.
13:34:34 <b_jonas> "I zqs spelling qll zeird qll the time." => the "m" in "time" is wrong

16:30:51 <arseniiv> you know the notion that a space has cardinality equal to sum of 1/N for each orbit where N is the cardinality of that orbit? Could we think of something simple having cardinality, say, 7/2? Can’t pair an odd number of elements, so the simplest approach fails

17:08:20 <Corbin> arseniiv: Have you read Baez & Dolan on this topic? A set with seven elements, quotiented by a set with two elements, will do the trick. We can think of six of seven elements as grouped in pairs, and then the seventh element is mapped to itself.
17:09:11 <Corbin> All of the pairs have two automorphisms (they're ordered), but the seventh element only has one because it's equal to itself; it counts for half. This gives 7/2.
17:10:22 <Corbin> https://arxiv.org/abs/math/0004133 explains this in painful but fun detail, building a weak quotient which has the desired property.

17:22:42 <arseniiv> Corbin: wouldn’t 6 paired elements need to be counted as 3 then?
17:23:27 <Corbin> arseniiv: Yeah, and indeed 3 + 1/2 == 7/2 in traditional arithmetic.
17:26:05 <Corbin> You can look directly at p13 of Baez & Dolan for some helpful diagrams. They use the example of 5/2.
17:26:30 <Corbin> (But you'll have to read the first half of the paper if you want the justification for why it's allowed.)
17:26:53 <arseniiv> I came up with a groupoid with objects in isomorphy classes of 1, 2, …, 33 objects, each one having two isos to each of isomorphic objects, one iso is a “direct” one and one is a “twisting” one, two twisting composing to a direct, and a direct from an object to itself is its id, thus all compositions are defined correctly and that’s indeed a groupoid. Then we have 33 isomorphism classes and each o
17:27:59 <arseniiv> Corbin: oh, thanks for the Tao link, didn’t read him about that
17:28:22 <arseniiv> Corbin: 3 + 1/2 = 7/2 oops I forgot how to calculate
17:28:52 <Corbin> Mm, so you'd have 33 isomorphism classes over a weak quotient of two automorphisms each, for a cardinality of 33/2? I admit that I still don't understand it fully.
17:29:24 <arseniiv> oh I forgot to mention my N was actually 33 and forgot that I simplified it to 7 but did elaborate in ##math afterwards. Lose track of two threads at once
17:30:28 <arseniiv> Corbin: I’ll read Tao and write with which of we wrote that aligns better
17:31:40 <arseniiv> oh a bit of a post got eaten off, it didn’t happen before to my client, it chunked overlong posts before
17:50:57 <arseniiv> Corbin: yeah, Tao indeed starts with weighing 1/|[x]| for each element x but then he shows this troubles uniform sampling and corrects that to 1/(number of isos from x), which is in accordance with counting just auts for a single representative of each isomorphism class

17:57:30 <arseniiv> ah, we could just have {−16, …, +16} acted by {x ↦ +x, x ↦ −x} after all. Then the corresponding groupoid will have two auts for {0} and just one for any representative of {−n, +n} for nonzero n, so overall 16 + 1/2 = 33/2
17:58:11 <arseniiv> now how could I make rot cypher with this…
17:59:01 <arseniiv> I need to treat almost half of the alphabet somewhat interchangeable but not totally interchangeable… eh
18:09:42 <arseniiv> I guess I made it unknowingly! x ↦ −x here is the rot-33/2 I looked for

22:43:06 <zzo38> Do they drag boats by horses?
22:43:51 <keegan> along canals yes https://en.wikipedia.org/wiki/Towpath
22:58:47 <zzo38> I was playing the GURPS earlier today, and that is what they did, or at least what they tried to do. But, the boat was too slow and the horse refused to move due to seeing something unsafe. So, instead we took the sign attached to the horse (we were trying to alert someone on the island) and attached it to the boat to use as a sail; fortunately the wind was correct for doing that.
