11:00 PM

I wanted to keep people from deleting all the items

Pavel

Is there some context I'm missing?

ATaco

Why is the auth token just stored in an input..?

wat

@Pavel There is an item list which has accessible delete buttons

@ATaco huh?

where"

ATaco

wat

ATaco

11:01 PM

Never trust a user, I unhid the input

wat

That's the hidden authenticity_token input

ATaco

There's also a tick.

wat

It's there to verify that the user is not a bot. It changes with every request.

Q: Renaming CSV files being imported in Python

I have a Python program which automatically goes to a specific website and downloads a CSV file automatically using a package called Selenium after it downloads the file it imports it into the program and outputs a graph. Problem: Everytime it downloads a file it is saved with a custom/unique n...

python

wat

The controller compares it with the internal value. If it's not there or has a different value, it raises an error.

@NewMainPosts No

Also, I will remove it in a few seconds by changing the input type to get.

@LuisMendo Once you boil down the fluff, it's literally just asking for the minimum of a list, with the first number /=3 beforehand.

Lolwut, how did I get the Announcer badge?

wat

BTW @ATaco No more auth token field.

Also the form now uses the method "get"

ATaco

Code like the world is actively trying to break everything you write.

wat

@AdmBorkBork What was your username before you changed it?

AdmBorkBork

TimmyD

wat

@ATaco I usually do that. The field is just a verification feature anyway, it's there for security not as a session token or anything

@AdmBorkBork Thanks

Congrats to @mbomb007 for being the second person to get the copy editor badge yesterday!

Riker

@flawr this shall go down in reddit history

Pavel

@Riker What is it? Can't reddit rn.

Riker

a guy promised to eat 1 habenero pepper per 100 upvotes

he's at 11.2k

rip

Pavel

This happens all the time tho

Riker

first time it's hit this many upvotes tho

wat

11:24 PM

upvotes changed

they now do not filter them to around 5K max

they are now unrestricted

@LuisMendo After removing the fluff, the challenge is "given [a, b, c, d], output the minimum of [a/3, b, c, d]". That's not sufficiently different from the list statistics challenge (in which one of the subchallenges is to output the minimum of the input list).

ATaco

That was probably for the best.

Anonymous

@ATaco This goes for you, too

Luis Mendo

@Mego They have a strong intersection, but each challenge has things the other doesn't, so maybe not dupe. Anyway, I agree it was not a very interesting challenge

Anonymous

11:30 PM

@LuisMendo There's also a meta discussion about splitting up the list statistics challenge into multiple challenges, in which case the minimum of a list challenge would be the dupe target.

Luis Mendo

Except for the "divide first by 3" :-) Not saying that's a very significant difference, but...

Anyway, I was just curious

muddyfish

It was easier for me to look at the other answers to understand what was going on than to read the actual spec

Pavel

Divide the first element by three could triple the length of a Jelly solution.

muddyfish

@Pavel I'd be surprised if it was only tripled

Anonymous

@LuisMendo Exactly - it's a trivial modification for many of the answers, thus dupe

Pavel

11:34 PM

@muddyfish Divide by 3 is two bytes, minimum is one byte, if I understood right.

Would it be correct to say that the worst-case complexity of Bogo Sort is infinity?

Anonymous

@Pavel But dividing by 3 would vectorize across the entire list, so you'd have to either head-divide-cons-min or input each argument individually, divide the first by 3, cons, then take the minimum

@Pavel Yes

pop 3 / push min

So... 4 bytes?

Not a very complicated action

Pavel

11:37 PM

I want to calculate the average time complexity of Bogo Sort, but I'm not really sure where to start >_>

DJMcMayhem

CMC: Return the minimum of a list where each item is divided by it's index in the list, one indexed

Anonymous

@DJMcMayhem That's not gonna work

DJMcMayhem

Why not?

Anonymous

Divide by zero

ATaco

1 indexed.

Pavel

11:40 PM

a->a.map(i->i/a.indexOf(a)+1) Almost works, but with the number of holes in it it would be easier to write a more naive approach.

Actually, I'm not sure. It could work.

DJMcMayhem

[1, 3, 5] --> 5, [2, 2, 2] --> 2

Pavel

@DJMcMayhem Java, 35 bytes: a->a.map(i->i/a.indexOf(a)+1).min(). Untested, might not work.

Anonymous

Actually, 9 bytes for 1-indexing: ñ`iu@/`Mm

Pavel

@Mego Explanation, please?

ATaco

RProgN, 15 Bytes ~10={01+`0=0/}R

Do I get points for using 0 as an incrementor?

Anonymous

11:44 PM

@Pavel Enumerate, for each { flatten, increment index, swap, divide value by index }, take minimum

Pavel

How do you set those bounds for the for-each in the program?

Anonymous

`stuff` pushes a function whose body is stuff

Anonymous

M maps a function over a list

Pavel

Oic

I din't notice the second `

Anonymous

So `iu@/` pushes flatten, increment, swap, divide as a function, and M maps that over the result of ñ

Pavel

11:46 PM

@ATaco Taking inspiration from Forte?

ATaco

I did it first. ;-;

Pavel

@ATaco Forte is from 2006

ATaco

I did not do it first.

But I did it independently.

Pavel

I think FORTRAN did it first.

ATaco

The 0 as an incrementor is just the function 0, 0x0 still pushes the value 0

~]L1\▬/ 9 bytes should theoretically work, but doesn't.

Pavel

11:49 PM

So, I just checked out your TIO link, it doesn't quite do what it's supposed to?

It returned a list.

ATaco

~{01+`0=0/}R min should actually work

Pavel

... Why, in a golfing language, is the builtin for minimum three bytes?

ATaco

min was one of the functions I created first.

RProgN is not a golfing lang.

Actually, I think I have a one byte builtin.

Pavel

Oh, I thought it was.

ATaco

Nope, I don't

Pavel

11:53 PM

So, it's very short, but nor a golfing lang. What you're telling me is that you made Perl?

ATaco

It's a language I wrote that I stuck golf functionality to.

The ZSS functionality might as well be called the golf function.

DJMcMayhem

MATL, 10 bytes: ttn:/tX>=)

Pavel

My Java solution is only around three times longer than the golfing langs ^-^

ATaco

`i 0 asoc function i 1 + `i asoc i / end replace min

That's the verbose equivalent.

Well, it should be, but for some reason it's erroring.

Googly Prettify makes this very pretty.

DJMcMayhem

Woah, that's gorgeous

Too bad it probably wouldn't work on mobile

Anonymous

11:57 PM

That actually looks pretty terrible

Anonymous

But I'm colorblind so I might be missing something

ATaco

Syntax Highlighting is its own beauty.
