#permutation and combination

they were wild for this

been very nostalgic for w359 lately. i think a huge part of why it has such staying power for me is that you can pick any two of the eight or so main crew members at random and go "oh those guys had a dynamic of all time." cause they did.

How to study math without ripping my hair out

A Math Problem

I spent most of the wedding I was at last night trying to figure this out with my cousin:

I have 3 sets: S, T, N

They can be paired: ST, SN, TN, but not TT, SS, NN.

Each set has 4 members: [S₁ - S₄], [T₁ - T₄], and  [N₁ - N₄]

There are 48 unique combinations (pairs): [S₁T₁, S₁T₂ ... T₄N₃, T₄N₄]

How can these 48 combinations be placed into 8 groups of 6, such that no group has any duplicate members, and each group contains 2 ST, 2 SN, and 2 TN?

Ex. [S₁T₁, S₃T₃, S₂N₂, S₄N₄, T₂N₁, T₄N₃] is a valid group

If the last combination was [T₄N₄] it would no longer be valid, because N₄ was duplicated. (It's also in [S₄N₄].)

If the last combination was [S₂N₃] it would no longer be valid, because there were 3 SN but only one TN, AND S₂ was duplicated.

If done correctly, every group will have one of each member. Every combination will be used once and only once. How do I figure out how to do this?

10/10 the best way to remember otherwise confusing terms in math is to assign blorbos from obsessions to them. Melkor the Morgoth has been helping me remember that order doesn't matter in a combination for about seven months now.

i love dnp doing math--dan was sort of right in saying that phil did 'whatever multiple of 4' combinations to get the final order correct. in reality it's a factorial (you choose 1 of 4 options, then 1 of 3, 1 of 2, 1 of 1) so you get 4 x 3 x 2 x 1 (or also: 4!) technically speaking, it is a mutliple of 4. (4 x 12) phil did a lot of shuffling but he didnt say 24 different permutations 😂

Ultimate Until Dawn Shipping Showdown

There have been millions of polls for favourite ships in Until Dawn already, I know, but the go-to poll format usually means that if you want to vote for a less popular ship your vote kind of gets wasted and the numbers get skewed

I am just the exact type of nerd who desperately wants to see the more detailed stat breakdown of things like this, so I had to take matters into my own hands

I put together a preferential voting poll instead

The way it works is that you order all the ships from favourite to least favourite. When the results are calculated, the ship with the least number of votes will get knocked out of the running, BUT! Instead of throwing away those votes, that person's second choice is counted instead. This keeps going until all the votes have been redistributed enough times to give an ultimate majority vote winner

The poll will be open for a week, I'll post the results then (assuming anyone actually voted)

Is this one of the nerdiest things I've done? Only publicly

VOTE HERE!

always intermittently thought about the magic of like "potluck cooking lesson gatherings at ben's" like, always hand over my heart imagining the one-on-one benston date concepts, winston & ben & tuk stemming off of being work friends....but now even if we never really have a chance to see the actual canon manifestation of [winston & rian taylor's quants duo + ben & tuk duo = Quartet] via like further scenes really, &/or at least that's not about basking in the character dynamic potential there....canon won't tell you this but after Day One of being kind and sharing the desks zone and hitting it off we get that quartet cooking with ben hangout that evening. taylor & philip pull a "oh we wanted to talk about something but yknow what we'll come to you" and join in, bonus

Finally starting to understand the math unit I missed while I was away omg...

A little something for Linguistics Tumblr.

So the Crunchyroll newsroom isn't a "room" so much as a Slack channel. We have news writers all over the US, in Australia, and in Japan. This means we have something akin to 'round-the-clock coverage, but it also means that our schedules respective to each other are skewed. For example, when the East Coast contingent is starting their day, the Japan contingent is shutting down for the evening.

Because of that, we started experimenting with greetings that could apply when Party A was coming in for the morning and Party B was leaving for the night. One person came up with "konbarning": a combination of "good morning" and "konban wa" ("good evening" in Japanese). It stuck.

Over the following months, "konbarning" got shortened to "barning" and other permutations. Now, a year or some later, this is how we announce our arrival:
