What's the smallest radius sphere you can pack 3 unit cubes into?

Themoonisacheese

07:20

@Ginger i need to buy a new processor for it but i have a server in my living room that i don't use fully

if you want a VM on it i can get you one in like, a week

@Simd a sphere of radius 1 has 4.18879020479 area, but it can’t possibly fit 3 cubes so it’s the lower bound

And radius 3 would be the upper bound

att

not necessarily

The Empty String Photographer

@Simd I’m thinking 2.5 + something

att

radius sqrt3 fits 8 cubes

The Empty String Photographer

Wait that’s the radius

I was thinking diameter

so 1.25 + something

att

where's this number from

The Empty String Photographer

08:00

Where something is the thing to make the circle slice that is 0.5 above the centre have a radius of 1.25

att

1.5 works with the cubes joined on an edge

probably can do a little smaller since that works for 4 too

@TheEmptyStringPhotographer what's 1.25 from

The Empty String Photographer

@att making a desmos graph

I’ll show yoy

emanresu A

I think sqrt(7.25)/2 is possible?

(about 1.34)

att

what's the arrangement for that

im not thinking of anything better than a grid triangle

emanresu A

att

08:09

tho maybe it can be wiggled a little

emanresu A

Then the longest diagonal is sqrt(1^2 + 2^2 + 1.5^2)?

att

but the longest diagonal isn't necessarily 2*radius

those diagonals don't cross at their midpoints

emanresu A

Ah true

att

i think optimal radius for that configuration is sqrt489/16 ~ 1.38

The Empty String Photographer

@att here

att

08:18

look up a couple lines

The Empty String Photographer

Yes I know

I was working on it while you guys were chatting

Themoonisacheese

y'all are getting awfully close to optimal square packing problems and i don't like it

The Empty String Photographer

It’s cube packing, actually

It’s harder than square packing

Now for another, even more difficult puzzle 😈

What’s the minimum side length of a cube to pack 3 unit spheres in?

(Sphere with radius 1)

att

seems like wiggling doesn't make it any smaller

The Empty String Photographer

I think upper bound is sqrt(12) = 3.464 for my problem

att

08:40

how do you get much better than 4

I can get 3.414 with a triangle of spheres at an angle in the cube

att

oh right

Seems optimal

Fun prank: pump carbon monoxide into a room where people are writing essays for an exam

Inspired by:

> I took a midterm in Doherty 2315 over the summer. It was very warm for some reason, and I fell asleep several times. I had a cheat sheet, which was very useful for waking me up when it fell on the floor. I kept waking up to nonsense written on my paper -- at one point I looked down and I'd been writing a paragraph about the Legend of Korra, a show I've never watched.

I may have found one of the steam tunnel doors, though it's more likely to be a hoax one

I've heard that any doors marked "hard hats required" are steam tunnels, and I found one in the B-level basement of one of the buildings that I know has one on its B-level basement, but someone had written "upper steam tunnel" in pen on the door and I doubt that'd be there (in an easily accessible hallway) if it really was one

I'm gonna try exploring another building today that I know has a steam tunnel connection

Ginger

@Themoonisacheese that would be nice, but a lot of my stuff is on Rydwolf's server and I don't have copies of it elsewhere, which is why I need that one specifically :p

I would appreciate it tho for the things I do have copies of

@Ginger i have 2 Tb on redudant ZFS, you can use it as a backup server if you want too

if you have discord ping me @Themoonisacheese and i'll tell you when the server is ready

it's gonna be at least until monday, the CPU in it is bad and it keeps hard crashing, i recieve the new one then

@RydwolfPrograms are steam tunnels still in use today? i thouight they were a relic of the past?

@mousetail they're already going insane with alzheimer's, no need to add to it

@lyxal do mods perchance have a tool for finding a chat user's network account that isn't checking the parent site

I need to do that for this userscript :p

There's a stackapp for that

script users chat

although it does user parent though

doubt there's anything outside of that

given the lack of a chat api

and the disconnect between chat id and site id

Ginger

that uses the SE API

which ig is what I'll have to do as well

Themoonisacheese

stackexchange.com/users/current ?

nevermind it just stays on the current site?

lyxal

using the API is better

Themoonisacheese

well yeah, if you can

@Bbrk24 ...Come to think of it, is it safe to use the built-in trimmer on an electric razor, or do I need a dedicated setup with guard attachments and whatnot?

Almost went through with this today until I realized how time-consuming it might be (when I have something else I'm kind of in the middle of even though I also just took a walk and am showering)

Rydwolf Programs

@Themoonisacheese District heating is still a thing, steam tunnels per se don't get built much anymore in favor of direct burial

Like, most of CMU's original buildings are (NOT) connected by steam tunnels (which don't exist and I have no interest in exploring them), but the newer ones use direct-buried pipes

I have a great idea for a site to troll hackers. It has every major vulnerability but all of them are just barely not exploitable

XSS but only on the "You have successfully logged out" page

SQL injection, limited to 4 characters at the end of a query

Buffer Overflow that could RCE except the program exits immediately afterwards

@192927376337929292283737373773 I have cooked up a userscript that lets two users voice call each other

Ooh.

and people like staff are going to be dressed in formal-ish clothes that you don't want getting sweaty in hot weather, while students do not have enough places to hang up winter coats in cold weather

And underground tunnels are easier to retrofit to existing buildings than above-ground climate controlled sky bridges

Which, incidentally, my university does have one of between a very new building and a very old building

So I have no idea what the problem is

hyper-neutrino

it's nice for all of the seasons except autumn when it's not really needed — winter because canada so sometimes you can get frostbite from 30 seconds of exposure, spring because the fucking geese, and summer because canada so also it gets really hot sometimes

Ginger

17:22

ideally what I would do would be use finallys to clean up each resource that gets opened

but of course, JS being JS, there's lots of callbacks and non-synchronous stuff involved

192927376337929292283737373773

Isn't the term for that asynchronous?

Which literally means but synchronous?
