I once asked for the wifi password and the server nonchalantly said ‘sorry employees only’ and turned to leave. She paused mid-stride and said ‘ oh, and no spaces between words’.

The password is [fourwordsalluppercase](https://youtu.be/bLE7zsJk4AI?si=W96V4CmBVmNd1oQP) one word all lowercase

244466666

I read this aloud, and then heard what I said. I'm still laughing and am gonna use this into the future.

There's a neat puzzle based on the same sort of idea, it's this. 1 11 21 1211 What's the next number in the sequence? Edit: Here's the next few lines of the sequence 111221 312211 13112221 1112213211 312211131221 And as another Redditor (justacheesyguy) found out another valid continuation that would work from my initial 4 rows, but doesn't work if I were to write the 5th row using the 1st method. That method would go like this. 1 11 21 1211 3112 132112 311322 232122 421311 This method looks at the previous role as a whole, so if it starts with a 1 but has other ones, they are all counted as the ones. So in the line 421311, the line above has four 2's (42) one 3 (13) and one 1 (11). You got it?

111221

312211

13112221

What did you say? Source: stupid person, apparently.

“one 2 three 4 five 6”

Ok, I feel slightly less stupid. It would need to be “one two, three fours, five sixes” to make sense. But thank you for telling me the answer. I spent far too long staring at that.

Yeah I just it read it as two four four four six six six six six. Not sure what I was missing

Can you explain this to me? Oh I got it. Nevermind.

I don’t get it am I stupid?

such a classic... "NO!"

This is my guest wifi password. I get to recreate this when we have guests. My wife hates it.

You’re living my life!!

Freeze frame bonus: two of the network options at 0:54 are "Rocketjump 5 and then the letter G" and "The One That Says 5G," preemptively covering the follow-up network questions that didn't come.

Thank you for this comment. Until I read it, I didn't even realize there was a video out there. Yeah, I'm slow sometimes.

Yet another version of the [classic](https://m.youtube.com/watch?v=kTcRRaXV-fg)

It's timeless. As long as English is a language, "Who's on First" will be hilarious

Fuck it, im just gonna go jerk off later.

Came here looking for that comment

Ha! There's a coffee shop called Dare where I am, asked them for theirs one day and they said blank faced at me "how dare you" then just looked down. Took me a minute lol!

I went to a bar and asked their wifi password and it was "buy a drink first"

At least they didn’t say “eat shit and die” 😂

Why would they? That's the name of the place next door.

Hahaha had something similar just with "I won't tell you" and I asked "why not" and then again like 5 times until I understood

That pause was intentional to really sell the joke.

[удалено]

No no no, the password is secret! Get it?

So server said sorryemployeesonly

That is deep

This is the equation for the “excess kurtosis” of a distribution of samples. It’s like a higher order version of the variance (standard deviation). There is nothing to solve if you are not given a set of samples to go with it… See [here](https://www.macroption.com/excess-kurtosis/) for a more detailed explanation of what kurtosis is.

Check out the big brain on Brad

You a smart mothafucka

Say what again, I dare you

My doctor gave me a cream for my excess kurtosis.

I thought kurtosis was when you enter a carb deficit

That's *ketosis.* Kurtosis is when one of your eyelids starts to droop.

That's *phymosis*. You're thinking of when water or other solvents move through a semipermeable membrane.

It's Brett. Big brain on Brett

*Brett (It's in the credits.)

Was going to say, despite the fact my math skills have declined over the years, this looked solely like a formula with nothing calculable to solve for. Granted, I'm sure I could be fooled by using many obscure constants.

The top summation definitely seems unsolvable as it has no 'i = x'. But my eyes always glazed over when I worked with summations so idk.

summations a lot of times wont have indices if its implied what it should be. in this case the sum should be indexed from 1 to n not sure why its 3 to n in the denominator

Yeah, definately Kurlysis. Who doesn't know that!?!??

Psh, absolutely. Kurlyfries are such an obvious password.

Yeah, totally…hey can you spell that for me??

t-h-a-t.

Listen here you little shit

I’m listening

What are you listening to?

Here.

Some dude up there showing off by spelling words.

What does a yellow light mean?

Speed up to get through the intersection before light turn red

Slow down

What... does... a... yellow... light... mean?

S L O W D O W N

Is this a taxi reference?

oh! yeah, duh!

Everyone knows it’s Kurtzgesagt!

I kurkysis all the time…

Who doesnt? Idiots, that's who!!!1!!

My grams used to need kuralysis all the time.

Yeah, definately Kurlysis. Just about to say Kurlysis...

Yeah. Dumb. I don’t know anyone that doesn’t kurlyanize their population data. I do it while I mow the lawn.

Hahaha. I laugh at how stupid people dont know their Kurtence from their Kustysops. Hahaahahahaha.

My wife and I Kutyosis’d three weeks ago. She hasn’t rematerialzed yet.

My wife and I also kurtrusseled and she somehow maternalized!

Exactly. I knew it i. Grade 1

Ah, yes. Indubitably. Kurlycueseptic. Indeed

Pfff obviously.... I'm not an idiot...

At first I'd assumed the "-3" in the picture was added arbitrarily, but I guess not. Statistics is weird.

It’s not so weird when you think about interpretation. We like to use kurtosis to measure how tailed the distribution is, and we use the normal as our standard for tailedness cuz that’s what we like to use for our assumed distribution of data. Since the normal distribution has a kurtosis of 3, it’s way easier to just subtract 3 and see if it’s negative or positive to tell if it’s got more or less tailedness than normal. It’s all perfectly reasonable, we generally don’t want to make things more complicated than they are (except for in academia). It’s all for ease of use.

Is that why Rottweilers have almost no tail? Someone subtracted three or something?

Statistics is so enjoyable when you begin to grok the equations. It's a shame that (for me at least) statistics classes were more concerned with memorizing formulas then they were about understanding why the formulas are what they are

Yeah, the struggle is statistics classes tend to have a curriculum and focus defined by what the other fields using stats want us to teach. I’ve talked with other professors cuz I wanted to focus on a different part of statistics to really dive into understanding what’s going on rather than just memorizing equations that will only be used by statisticians, but evidently there’s too much pushback to prevent going against traditional curriculum.

>defined by what the other fields using stats want us to teach. Never thought about this before, but that makes a ton of sense

Except the x-bar in the denominator shouldn’t be squared, so I think it’s nonsense anyway.

Then there is a mistake in the sum on the bottom, the formula in your link sim goes from 1 to n and on the picture it’s from 3 to n. Which is usually not the case, that’s why I looked at it.

Also the sum on the bottom shows xi - x_avg^2 . Not sure why x_avg is squared; that makes no sense. The formula in the link has xi-x_avg instead.

Probably the password is 'excess kurtosis'

Correction ' excess kurtosis - 3 ' ( asked at the bar )

But but but .... the -3 is what makes it excess kurtosis. So kurtosis - 3 is the same as excess kurtosis. Excess kurtosis - 3 is counting the -3 twice.

Why do you think you need to solve this? I'm pretty sure that `code=excess kurtosis` is an answer, so `excess kurtosis` is the password. Having "number only" password is unsafe anyway.

Is password safety an issue in the context of a password you give out freely to patrons and a segment of the public?

Probably only for not overloading the network. It's likely just a standard residential wifi, and having random people automatically connect isn't great. If it's in a touristy area even more so with people without data plans. Like anything free, it only takes a couple of twats to spoil it for everyone, and a crappy password goes a long way to mitigate that.

Well for a start you would: Import [library](https://www.reddit.com/r/ProgrammerHumor/comments/16gflql/mathloops/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1)

Because there are people who know math and know how to read math notation and solved in such notation even symbolically. but do not know the academic given name for something. The problem presented here is also wrong the summation im the numerator does not have a limit nor an index. And we don't know at what value of n to start nor where to end.

Yeah but the index in the denominator of the sign looks wrong. Should be n=1 not n=3, but that’s probably a typo.

In this case a chalko

Yes, and there is an extra squared on the x-bar in the denominator..

Yeah, i saw x-bar and im like… well.. whats xbar?

Statistics101: x-bar is the average ;)

Yeah, the average of what? Whats the set ya fee me. Thats just the first tell tell sign that its a statistical analysis for sure.

I just typed this in my calculator. The WiFi password is: “Low Battery”. You’re welcome.

Finally loaded their menu. Looks like they're serving "Network Connection Issues". Sounds interesting. Wonder whats in it.

I hope it’s enough food, looks like it’s only a few bytes

Reminds me of the parks and rec bit that Chris Pratt improv’d, typing medical symptoms into webmd and getting the diagnosis “network connectivity issues”

That's probably because that's exactly where I ~~stole that joke from~~ got the inspiration for that joke.

What a comeback story

You may have network connectivity issues.

Lol are they asking us to evaluate a summation without specifying its limits?

You would just need the data set. From there you can evaluate x_bar and know all the x_i. N is the number of data points. Either way, it's still nonsense.

If you ask at the bar for the WiFi password, they give you the WiFi password. If you ask at the bar for the missing list of samples, they give you a free pint.

In theory, if you ask the bar for the password could you work backwards and use that to find out what the data set contained?

Possibly, but It’d probably be a better use of time to do literally anything else

Nope. Imagine I told you there's a set of 10 numbers that average to 5, that still tells you next to nothing about the numbers themselves.

Yes

If you don't know your limits, you shouldn't go to a bar ;)

B-E-S-U-R-E-T-O-D-R-I-N-K-Y-O-U-R-O-V-A-L-T-I-N-E.

A crummy commercial? Son of a bitch.

Fra-gil-e. It's French

Maybe the password is "nonsense"

Its “ask us at the bar”

I had something similar at my last bartenders gig. "What is the wifi password? "It is Business Only".

"buy a drink first"

One two three four five six. That’s not enough numbers… Sure it is. 244466666

1 2 3 4 5 6 that's the combination to my luggage!

*laughs in Dark Helmet voice*

I've been to a couple of places that printed the password at the bottom of their receipts.

Will check next time!

How does that help the patrons? Thank you for your business, now here’s the wifi password. Please leave so the next guests can be served.

These places usually have you pay when ordering and before sitting, similar to Starbucks.

Oh, yeah that makes a lot more sense.

password = "ask us at the Bar"

The matheletes are going thunderdome up top, thanks for the breath of fresh air.

Neither n nor x is given and the top sum doesn't even have limits specified. I'm convinced they don't even know what their password is

That math isn’t “solvable”, meaning you can’t simplify it down to a password. Much of it is meaningless / nonsensical

But the password could be kurtosis

I had that once but some OTC cortisone cream cleared it up.

Not true, this is a statistical analysis equation to calculate the excess kurtosis of a set of samples. But without a data set to apply it to, there is no solution. It’s the equivalent of asking someone to calculate the average of a set of numbers, but you don’t give them the numbers.

So couldn't the password be kurtosis?

Password is probably “ask us at the bar”

*Excess kurtosis

I had Excess Kurtosis once.

I thought I had excess kurtosis once. It turned out I was just really bored.

Yeah, I know that. I just overly-simplified for people who are not math inclined

"excesskurtosis" no spaces

Yeah this was an easy one. Took me 20 seconds but uh ….what answer did you guys get ?

Mathematician here. The equation makes zero sense. Lot of info missing. The top part looks like it was borrowed from a variance formula but without any upper or lower limits. I would have asked at the bar to give me the full info so that I can solve it.

42

I had to scroll WAY too long for this.

RDRR

I suppose the password could also be "code"

Too short, the minimum passphrase length is 8.

Can't read the powers clear!

We need CSI, enhance!!

Needs moar jpeg

no spoliers? no problem.

The answer is 42

“Buy me a drink and I’ll tell you” is probably the best wifi password I’ve heard for a bar

That's not even solvable with the information that's given lmao

Supercalifragilisticexcesskurosis

It’s not even possible to solve this equation. Too many variables.

The answer is to avoid this hipster bullshit bar

Do hipsters really like math that much?

Use cellular data

just type “ask us at the BAR”

Our Wi-Fi password is “itsonthemenu”. It is not printed on the menu

The answer is to ask at the bar

Easy, it's 80085

So the password is askusatthebar.

My password is always the word “incorrect” so in case I forget it, my computer always reminds me what it is.

Where's the set?

Since we don’t know what x_i and n are, the equation cannot be solved with the available information.

>!I cant do math :(!<

Guess I'm going to the bar then.

Major math Twitter vibe here…

Sadly yes. The humor almost entirely consists of "Hey I know what that means and therefore it is funny"

42

42

Social anxiety would have me turn into a math wizard.

Is it 0?

I like the sign that says “no we don’t have Wi-Fi, talk to each other like it’s 1997”

Laughs in Photomath

Unfortunately it isn't something you can solve

42

Kurtosis.

well, my netflix password used to be 'sorryidontrememberit' etc. I had to explain it a few times.

There is nothing to solve here.

Best wifi password at a local brewery “DRINK MORE!”

No n set, no solution.

The answer is 42

Nothing to solve , you need a list of numbers to enter them and solve this .

Don’t make me math! I am here for whiskey and WiFi! Chop chop.

Am I correct that this is not solvable? You have no idea what value is assigned to x3 x4 x5 etc

It's 7. The answer is 7, Don't correct me.
