Do you really want your missile to fail because it got a BSOD? :P

Ginger Industries

@emanresuA lemme look for it

user

Ooh, a blue missile in the shape of a screen would be so cool, you could name it the Blue Screen of Death :P

Ginger Industries

@emanresuA sorry meant @PyGamer0

@dzaima Is the first an actual use case?

@user i have zero clue

actually, no, removing /dev/ or /bin///usr/bin is gonna be bad in any scenario

A: Sandbox for Proposed Challenges

Von Neumann Probe Battle (king-of-the-hill) This is just an idea for now, placing it here as a draft and to collect feedback. Basically, your goal would be to design a set of machines, including factories and spacecraft, which start on earth and spread outward into the universe. You'd be able to...

Ginger Industries

@SandboxPosts @taRadvylfsriksushilani This feels like the "Tetris in Conway's Game of Life" thing: ~~awesome~~ impractical.

ta Radvylf srik su shilani

I'm thinking it would revolve more around designing physical bots than actually writing code

Ginger Industries

@taRadvylfsriksushilani ...oh no

oh no

WE WERE JOKING WHEN WE SAID END THE WORLD

ta Radvylf srik su shilani

E.g., you'd have rocket boosters, mining drills, storage areas, and other stuff you could chain together

Ginger Industries

22:10

@taRadvylfsriksushilani oh phew I thought you meant physically design and build

that was close

ta Radvylf srik su shilani

So you could optimize your probes for different tasks (some start mining immediately, some collect materials, some handle combat, some build other probes or factories), or you could make them all more general purpose

Ginger Industries

@taRadvylfsriksushilani so what you've got here is what we call a "videogame"

ta Radvylf srik su shilani

Sort of, yeah. This is a KotH, and those are rather close to video games.

Ginger Industries

@taRadvylfsriksushilani well yes but this one specifically is a really cool idea and now I want to make it

ta Radvylf srik su shilani

Good luck :p

Ginger Industries

22:13

@taRadvylfsriksushilani I'll add it to the infinite list of cool ideas that never get made

user

@GingerIndustries We were?

*backs away from red button*

Ginger Industries

@user not again

ta Radvylf srik su shilani

I wonder if, if one day someone told me I would literally never die, if I would finally get around to finishing all of the projects I've come up with, or if I'd just keep coming up with more and more and my backlog would reach infinity

Ginger Industries

@taRadvylfsriksushilani let's test

@taRadvylfsriksushilani You will literally never die.

user

Eventually, you'd finish them even if your backlog just got bigger

Ginger Industries

22:15

and now, we wait.

user

Finish one, think of ten more, finish another, think of ten more

ta Radvylf srik su shilani

@user That's like saying x - 1 will equal 0 someday

Oh, well I guess each individual project you mean

user

Yeah

ta Radvylf srik su shilani

I work on my projects like a stack, not a queue

So not necessarily

user

Alternatively, you might just go crazy one day and neither finish projects nor come up with any new ones :P

Ginger Industries

22:16

so if you have too many
would you experience
STACK OVERFLOW

user

@taRadvylfsriksushilani The amazing human brain

@GingerIndustries Nah, the bottom of the stack kinda just gets forgotten :P

Ginger Industries

RIMSHOT

user

(at least, that's how it works for me)

Ginger Industries

@user idea: esolang that uses a stack where items that haven't been accessed for too long are removed from the stack

ta Radvylf srik su shilani

I feel like my massive inactivity streak on main might be coming to an end

Ginger Industries

A: Sandbox for Proposed Challenges

Who Loses? Task Your task is to take a Dictionary input, and a winner input. You can assume a dictionary where the winner input is the first element. A input: [{"Joe": 800, "Mama": 1000, "Biden": 1200}, "Joe"] Means that the aproxximate score winner is Joe, The next is Mama, Mama is greater than...

Fmbalbuena

@Adám @others Any feedback?

Ginger Industries

@SandboxPosts feels like a dupe

Fmbalbuena

@GingerIndustries why?

ta Radvylf srik su shilani

I have no clue what this challenge is asking you to do

Fmbalbuena

@taRadvylfsriksushilani Give me a example

Ginger Industries

22:26

@taRadvylfsriksushilani find the largest value in a dict and return its key

ta Radvylf srik su shilani

Doesn't seem like it

What's the second input for in that case?

Ginger Industries

@taRadvylfsriksushilani ...looking at it again you're right I'm confused

Fmbalbuena

(input is [dict, string])

ta Radvylf srik su shilani

What do the numbers in the dictionary stand for?

Fmbalbuena

@taRadvylfsriksushilani Means the numbers that he thinks in a number guessing game.

ta Radvylf srik su shilani

22:28

Ohh

Fmbalbuena

@taRadvylfsriksushilani Can you help me to rewrite the challenge?

ta Radvylf srik su shilani

Problem: If A guesses 100, B guesses 200, and C guesses 300, and B wins, who loses?

There's no way to know if A or C was closer

Fmbalbuena

> If there is a tie, lower wins.

ta Radvylf srik su shilani

So, find the farthest guess from the winner, and return its key?

Fmbalbuena

Yes

@taRadvylfsriksushilani Then is there a way to rewrite?

ta Radvylf srik su shilani

22:31

Yes. You need to clarify that it's a number guessing game, and what the parts of the input actually mean.

Fmbalbuena

> Your task is to take a Dictionary input, and a winner input. You can assume a dictionary where the winner input is the first element.

ta Radvylf srik su shilani

But you need to clarify what the dictionary does. That the keys are players, and the values are their guesses.

Fmbalbuena

key?

ta Radvylf srik su shilani

"a" is a key in {"a":4}

Fmbalbuena

^ I don't understand why this is a player

ta Radvylf srik su shilani

22:34

Two different meanings of the word "key"

A dictionary has "keys", that's what the player names are in yours

{ a: 100 }
  ^         key
     ^^^    value

Fmbalbuena

@hyper-neutrino Can you timeout This for 14 days with mod abuse?

ta Radvylf srik su shilani

I kinds want to start working on Hunter-Gatherer KotH again, but I feel like that would be another distraction from RTO

Adám

@Fmbalbuena I don't understand the challenge.

Fmbalbuena

@Adám why?

Adám

The combination of its formulation, with my pre-existing knowledge and intelligence, does not cause me to understand it.

Fmbalbuena

22:47

@Adám @taRadvylfsriksushilani explain, then @Adám Reword

ta Radvylf srik su shilani

It's not really clear what you're asking us to do

Adám

@Fmbalbuena I think you need to understand that commandeering people is not nice.

Fmbalbuena

@Adám ok

user

23:00

@Adám Maybe Fmbalbuena was asking which specific parts of it were unclear so they can fix it?

Adám

The whole thing, then. ⍨

Fmbalbuena

⍨?

user

lol

Adám

I use ⍨ as a frown.

aplcart.info?q=frown

Fmbalbuena

@Adám Do you have any doubt with the challenge?

ta Radvylf srik su shilani

23:02

Adám's likely confused for the same reasons Ginger and I were

You need to clarify that it's a number guessing game

Adám

What exactly defines who loses? Is there significance to the order of the input? What is an "aproxximate score winner"?

Fmbalbuena

@Adám edited

Adám

> You can assume a dictionary where the winner input is the first element.

Dictionaries are usually unordered.

ta Radvylf srik su shilani

How about "Your task is to take a dictionary of guesses as input, along with the name of the winner. You should then return the name of the player whose guess was the farthest from the winner's, or if there are multiple, the lowest."

Adám

So does this mean we can take a list of key-value pairs where the first is the winner, rather than taking the winner key separately?

ta Radvylf srik su shilani

23:07

For the flavortext, "You are playing a number guessing game. You know everyone's guesses, and who won, and want to figure out who was in last place."

Fmbalbuena

@taRadvylfsriksushilani done

Adám

If the challenge indeed that, then all the key stuff is red herring: Given a list of numbers, return the number that has the largest absolute difference from the first element, and the lower of the two if there's a tie.

ta Radvylf srik su shilani

A chameleon challenge

Fmbalbuena

@Adám I don't want to return the number

@taRadvylfsriksushilani why?

ta Radvylf srik su shilani

@Fmbalbuena The name stuff just gets in the way

Adám

23:09

@Fmbalbuena So return the index of the number.

Fmbalbuena

@Adám no, the key

Adám

What would [{"A": 100, "B": 200, "C": 200}, "A"] give?

Fmbalbuena

@Adám "C"

Adám

@Fmbalbuena But the whole key→value and then value→key lookup has nothing to do with the core challenge, which is to find the furthest distanced number.

ta Radvylf srik su shilani

I assumed the guesses are unique, maybe that should be clarified

Adám

23:10

@Fmbalbuena Can you explain why it is C and not B?

Fmbalbuena

@Adám Because C loses

oh wait, this input is invalid

Adám

Why?

Fmbalbuena

@Adám because "B" == "C"

Adám

So? I don't see anything in the spec that rules out such a case.

Adám

What exactly do you mean by "You can assume that input gives non-deterministic output"?

ta Radvylf srik su shilani

Likely a mistake in the wording

Fmbalbuena

@Adám I think i will remove this.

ta Radvylf srik su shilani

"All guesses are guaranteed to be unique" might be closer to what you meant

Adám

I think it is a pretty good challenge IF you remove the whole key-value distraction.

Fmbalbuena

23:17

@Adám how to remove that?

ta Radvylf srik su shilani

Just make it so you take the guesses as input, and return the number

Adám

If the challenge indeed that, then all the key stuff is red herring: Given a list of numbers, return the number that has the largest absolute difference from the first element, and the lower of the two if there's a tie.

Fmbalbuena

Ok, i will rewrite.

Adám

Well, return either the number itself, or its index.

ta Radvylf srik su shilani

So your input would look like [[100, 200, 300], 300], and your output would look like 100 (or 0/1)

Adám

23:18

@taRadvylfsriksushilani Or just let the first number be the winner.

ta Radvylf srik su shilani

Yeah. Went with the same I/O from the sandbox post for clarity

Adám

It originally said the winner would be the "first"(!).

Fmbalbuena

Oh

[[100, 200, 300], 200] gives non-deterministic output

Adám

No, the answer is 100

Fmbalbuena

@Adám But uhh

Adám

23:21

What?

Fmbalbuena

This list [[100, 200, 300], 200] and the number was 240, 100 loses

or

This list [[100, 200, 300], 200] and the number was 160, 300 loses

@lyxal hi

it's 12:22 here

Adám

@Fmbalbuena Not right now. I need to wash dishes.

Fmbalbuena

@lyxal Sorry it's too late to talk me, I have to gtg.

@Adám ok, when you come back, try to rewrite

att

@lyxal wth

lyxal

@mathcat then you should go sleep

@att it is what it is

mathcat

okay g'night

ta Radvylf srik su shilani

23:33

@lyxal That's essentially what any bitcoin mining operation is :p

Or computer, for that matter

lyxal

@taRadvylfsriksushilani but can you use your laptop as a dedicated room heater? I didn't think so.

ta Radvylf srik su shilani

Arguably, you could, it would just be stupid :p

Adám

@lyxal I've used my laptop to keep my hands warm.

lyxal

@Adám that's not the same scale as the bitcoin heater I'm talking about

Adám

True.

But like, in places with cold weather, energy could be saved by using heat from data centres for heating houses.

lyxal

23:39

@taRadvylfsriksushilani good luck getting it to keep an area of 150-170 square feet warm

@Adám yeah, that's basically the same concept as the heater

ta Radvylf srik su shilani

Every bitcoin transaction uses enough electricity to power a lightbulb for 14 years

att

finally something useful

emanresu A

Cryptocurrency-based heat is a clever idea but it doesn't make it any less of an environmental disaster.

ta Radvylf srik su shilani

Well, idk. In theory it's identical to resistive heating.

But there's less direct stuff, like consuming supplies for computer chips, which are in short supply right now, on your space heater

or encouraging more people to use bitcoin (or buy another warehouse of ASICs) in the first place

I seriously think my semi-decentralized system would work considerably better than PoW/PoS fully decentralized stuff

The idea of a blockchain is, IMO, completely idiotic for 99% of applications, including currency

At least Ethereum's probably moving to PoS, so it'll just be idiotic instead of idiotic-and-ice-cap-melting

Adám

PoS? (I keep wanting to read that as something obscene.)

ta Radvylf srik su shilani

23:50

Proof-of-Stake

Adám

Ah. Thanks.

ta Radvylf srik su shilani

Where instead of trying to break hashes, it's based off of the amount of the currency you hold

Adám

I thought PoS was taken in the tech world for Point of Sale.

ta Radvylf srik su shilani

Well, now it'll be in two lists at once: initialisms that have multiple technology-related definitions, and words that bring to mind obscene things

With "Wireless Access Point" having recently been added to the second
