Path that maximises time would be some kind of space-filling curve. Maybe it does that off panel?

Basically, yes. The path that maximises time goes around the world, so starts by going up off the top of the screen, and re-enters at the bottom.

Technically I think it could be a little longer by spiralling around the world several times, still reaching the target point despite going “in a straight line”. If we ignore the “straight line” restriction, which some of the other paths already do, then the sky’s the limit. Technically actually, the sky isn’t the limit, and the path could criss-cross over the whole planet first, and the air, and the whole galaxy, before reaching the destination as the last feasible space to arrive at. Personally I think that’s too complex for xkcd, if they are going for complex I’m sure they would have come up with something about paths through n-space and black-hole theory that is beyond my pay grade.

Xkcd good ;)

It would have to be a different panel but you could draw it as the whole screen being black except of the character and the destination.

If it’s a space filling curve as Octoperson suggested, it wouldn’t need to be big. Isn’t a space filling curve infinite length if its offset is infinitesimal?

It’s the path that maximises time, not distance. Technically the path that maximises time could look the same as the path that minimises distance, they could just sit down and wait decades until a minute before they die of natural causes and then get up and head to the end, and that’s assuming that they need to arrive alive.

path that maximizes time? just don’t move. at all

Gladaed ,

It’s to do with light paths and diffraction. The time maximising path still hast to be a valid path.

I spent way too long trying to figure out why the guy and the ice cream shop were flying, and how he would move horizontally in he air…

floofloof ,

I couldn’t tell what I was looking at until I searched for an explanation. All I could see was a person falling into some water past a floating ice cream stall. It’s supposed to be a beach:

“we have a beach at home”

the beach in question https://mander.xyz/pictrs/image/dc0fe690-1c7b-4a9f-8337-738f90745bff.jpeg

demlet ,

Yeah, I just thought it was two dudes racing to get ice cream first.

angrystego ,

I was more like: but if he choses the alternative paths, he doesn’t get the ice cream - that doesn’t make sense! Then I understood our priorities differ.

Alt text.

Of course you get an ice cream cone for the swimmer too! You’re not a monster

Now I want to see someone swimming with a cone of ice cream in each hand.

roguetrick ,

You want me to wear my swim trunks or get a bikini.. Warning before your answer: only one body type has the bouyancy to pull it off.

Thisfox ,

As an Aussie, I don’t see why that is unusual. You use your feet. But if it’s only two icecreams, then you hold them both in one hand and swim with the other one. All I can say about this one though is that this is a very flat beach: Waves would ruin the icecream pretty bloody fast.

Viking_Hippie ,

Do people not swim with icecreams in other countries?

Never heard of anyone doing it no, so probably not? 🤷

Thisfox ,

Huh. Stuff I never expected to be unique to Oz.

Swimming with something that can’t get wet is not unheard of here. I sometimes swim a book over to somewhere to read, or a phone to a good place for a photo too.

Viking_Hippie ,

See, that IS completely unheard of here! If it’s not supposed to be wet, we wouldn’t dream of swimming with it!

I don’t know if it’s because you guys are born excellent swimmers like Norwegians are with skiing, but I don’t know ANYONE who wouldn’t assume that swimming with something invariably means getting it wet 😄

WndyLady ,

What’s up with that? I can’t see any of the pictures hosted here.

colforge ,

I’m not positive but it might be due to the steps the Lemm.ee admin is taking to combat the CSAM uploads that have been happening and prevent the server’s administration team from being liable for potentially harmful and illegal images being hosted on their server.

I love that the transcription has the correct labels for those of us who aren't sparkies.

Jakylla OP ,

Not sure that this transcription is useful for person with vision disabilities unfortunately, would need some description of the symbols I think

TWeaK , in xkcd #2818: Circuit Symbols

That is a cool diode.

xuxebiko , in xkcd #2818: Circuit Symbols

This is hilarious.

Contortion , in xkcd #2818: Circuit Symbols

I'm getting the urge to listen to Metallica

omgarm , in xkcd #2818: Circuit Symbols

It’s been a while since I had electronics in Uni but this seems accurate.

Chadus_Maximus ,

Don’t worry, someone will eventually come and tell you that it isn’t.

meatand2veg , (edited )

I could resist the urge… But… Uh… The transcript incorrectly labels the symbol for capacitor, it’s actually the NEMA symbol for a contactor. Had to make sure I wasn’t sobbing my foot in my mouth. Capacitor symbol is extremely similar, but the right side needs to be bent like a parentheses foot it to be a capacitor like -|(-

That took me a couple minutes to actually grasp what is where. I like the idea of NYC being in the Himalayas, and I’d love to see that.

oh hey it me

AI_toothbrush , in XKCD #2819: Pronunciation

I didnt know gyro could be pronunced in multiple ways

stringbeantheory ,

the greek food gyro is kinda pronounced "yee-ro"

Skua ,

There's gyro as in gyroscope, where the Y vowel sound is like the word "eye", and there's gyro as in the Greek sandwich where the Y vowel is more like the vowel sound in "sea". The latter is often seen only as "gyros" because that's what the actual Greek word is, but because that seems like a plural in English the S is sometimes dropped.

AI_toothbrush ,

Ohh gyros as in the food lol

positiveWHAT , in XKCD #2819: Pronunciation

The english language is … missing some litterary updates.
A is pronounced [ei]. E is [ii] and I is [ai]. What’s up with that.

e_t_ Admin ,

I started learning Japanese recently. It's made me realizehow sloppy English is with vowel sounds.

dot20 ,

IIUC the problem is that they updated the pronunciation without updating the spelling: en.wikipedia.org/wiki/Great_Vowel_Shift
