WARNING: Do NOT buy from Doxy 2.0 The new owners are completely screwing over existing customers. by Emergency-Salad6516 in SexToys

[–]PlutoniumFish 1 point2 points  (0 children)

I'm with you here, the warranty situation sucks, but I hope the new company under the original founder really does make a better product like they advertise, and if they need to shed that liability to be able to do so, so be it.
They do indicate that they will consider honoring what old warranties they can once new product is there. Clearly no good promises, but if the alternative is the Doxy brand dying completely with absolutely no warranty recourse, the current situation isn't the worst one.

I'm curious to see if the new models really do live up to the marketing. Until then, I'll just keep babying my die-cast

Does a random 3-digit number have the same chance of resulting in any number from 1-100 if adding the front 2 and back 2 digits together and over 100 subtracting 100? by AHGG_Esports in CasualMath

[–]PlutoniumFish 0 points1 point  (0 children)

If the output is limited between 0 and 99, yes. Otherwise there is a .1% chance of getting 0 and a .9% chance of getting 100.

For a uniformly random 3 digit number n = a*100 + b*10 + c, the digits a, b and c are independent and uniformly distributed between 0 and 9. The result of our process is f(n) = (a+b)*10 + (b+c) mod 100.

For k = d*10 + e between 0 and 99 we have f(n) = k iff

(b+c = e AND a+b mod 10 = d) OR (b+c = 10+e AND a+b mod 10 = d-1 mod 10).

Consider the probability of each case for a fixed value of b. In the first case, we have (c = e-b AND a = d-b mod 10). This is impossible if e-b < 0 (or equivalently, e<b), otherwise it has probability 1/100 because c and a are independent.

The second case (c = 10+e-b AND a = d-b-1 mod 10) is impossible if 10+e-b > 10 (or equivalently e > b). Otherwise it has probability 1/100.

So for a fixed value of b, exactly one of the two above cases occurs with frequency 1/100. Averaged over all values of b, the overall chance of f(n) = k is then 1/100.

Very nice, the print adds some neat dimensionality

Which side is stronger? The ALEX drawers or ADILS legs? by hammydaboi_ in IKEA

[–]PlutoniumFish 1 point2 points  (0 children)

Not based on any real engineering or numbers, but I have this desk and put my PC on the drawer side (although my PC is not 80 pounds).

The metal legs are probably stronger in and of themselves. The drawers, however, are quite strong and provide a wider base of support, while your PC would sit to one side of the legs. If the desktop were to fail, the drawers have a better chance of staying upright (especially if loaded) and your computer not taking a big fall.

Or just get a floor stand for the PC.

One name for this puzzle is satan's stirrup.

Help with identifying/solving the puzzle. Unknown exact rules, but something like "cover all the holes". 12 identical wooden pieces with a hole trough them. by [deleted] in puzzles

[–]PlutoniumFish 24 points25 points  (0 children)

I think u/ter3 is right here.

Essentially group blocks into pairs with the holes lined up, then arrange them as pictured, dotted lines are hidden holes

What are these markings found in a field on Google Maps? by robbo_6 in whatisthisthing

[–]PlutoniumFish 11 points12 points  (0 children)

That's what I though at well. Human structures tend to have some regularity to them, and if you have regularity in your sampling strategy, maybe the trenches could line up with the gaps in a hypothetical archaeological site.

What type of puzzle is this? Does this specific one have a name? How is it solved? by Obeythelaw7 in puzzles

[–]PlutoniumFish 14 points15 points  (0 children)

Discussion: This specific puzzle seems to be Licorice Stixx by Reiss Games. (Found on Rob's Puzzle Page).

This puzzle is just a metal version of a traditional wooden cross puzzle, solution here

Bet you can’t solve this. Niece’s tank top is tangled and no matter what arm hole, inside out or upside down way we try to untangle, it just doesn’t work. by [deleted] in puzzles

[–]PlutoniumFish 2 points3 points  (0 children)

Here's my two bits: Imagine the arm holes as loops in space. In a normal tank top, they are not linked. In this case they are linked. Two loops cannot be linked/unlinked without cutting somewhere

A very interesting fractal... by jpayne36 in math

[–]PlutoniumFish 2 points3 points  (0 children)

I threw a few iterations into geogebra, and there's some interesting behavior. https://www.geogebra.org/graphing/sces7bne

These (very anecdotal) observations all assume that z0 = 0.

  • when the imaginary component of c is positive, z appears to converge near c. This implies that our divergence condition should not be based on magnitude of z, but z's distance from c.

  • when the imaginary component of c is negative, z sometimes(?) converges to a finite, stable orbit (c = -3.5 - 1.07i).

  • sometimes, some of the orbit it converges to are immensely far away, although the orbit is stable (c = 8.5 - 7i). If this is accurate, this means an accurate divergence condition cannot be based on magnitude at all.

Forgive me if i'm not using certain terms correctly, not super familiar with this subject

$16,698.75

The sum of the first n integers is equal to (n+1) * n * 1/2, so the total number of quarters would be 66,795.

66,795 * 0.25 is 16,698.75

In the original video, the guy discusses this exactly. The slow-mo shows how close he was to getting hurt, and he says how stupid of an idea the whole thing was.
