@EᴀsᴛᴇʀʟʏIʀᴋ Woah! Let me try: **************
@quartata then what about "unscramble eval"? There's too many ways around it
@DrMcMoylex **** ***
@NathanMerrill Unscramble how?
@DrMcMoylex While you're on here, do you think this sandboxed challenge would be considered a dupe of your "What year was this language released?"?
00:07
Basically mego's answer, but without hash checking. Simply put a try catch, as well as check the ast
@ETHproductions No, I think it's good
@NathanMerrill The AST can be reversed into the original code though.
And it'll generate valid programs that don't get caught
Anonymous
@NathanMerrill That sounds like a fundamental problem with the challenge, then
So I don't see how that helps
FWIW, my "what year" was originally closed as a dupe of versatile integer printer
Anonymous
00:09
@NathanMerrill Your latest attempt to fix the problem just makes it worse
@NathanMerrill The current phrasing suggests that if there exists an input that will take an hour to compute the result for, the answer is not valid. This means basically every non-trivial challenge. — quartata 10 mins ago
Makes it downright impossible.
@quartata not if I just check the depths of AST
@NathanMerrill So?
That doesn't mean that's the program
You could craft a program so that the depths will only match. This is an obfuscation challenge, not a "unscramble" challenge
It's highly unlikely that there won't exist another program with the same subtree heights that comes first
If it doesn't exist than that's a pretty defining characteristic -- would certainly make it easier to crack
00:20
There could exist another program, but it likely wouldn't take input without throwing an error
That's language dependent.
and not true methinks
tell you what: make an answer like that then we'll see
OK: consider this: the unscrambled program stores it's source code in a variable, and checks to see if its equal to a string it's generated (a quine in a sense)
If that isn't true, it throws an error
So, right now I am "participating" in a Hackerrank competition being hosted at my university... PPCG has spoiled me, they are really bad at writing challenge specs.
3
The only way I could see this being a problem is if the language had coroutines
Anonymous
@quartata How so?
00:28
Actually, nevermind. That wouldn't even help
Option 2: write 2 or more programs: scramble them both using the same seed. Unscramble them both in tandem, eval then both, return the answer of they match
Anonymous
@NathanMerrill You still haven't addressed this:
Anonymous
Within an hour on which computer? — Mego 53 mins ago
I edited the question. On a typical consumer computer
Anonymous
That's still not very objective
00:34
Still feels like you're reaching for straws
The bottom line is currently the challenge is impossible
pls fix
We do it on plenty of other challenge
Anonymous
I could devise a program that would run in under an hour on my desktop but not my laptop. Both were purchased within the last 5 years.
I agree, it's not completly objective. But unless you are going to close every challenge with such requirements, it remains open
@quartata it's not. Literally every other submission is currently valid
Anonymous
@NathanMerrill That's tu quoque. Try again.
There exist inputs that take an hour for basically every challenge
00:37
Look at the edit
Anonymous
It's a duct-tape patch. The underlying issue still exists.
I'm looking at it.
Anonymous
Perhaps the challenge should go back to the sandbox for a while.
It's based off of the test cases
> if a challenge takes numerical inputs
And for non-numerical ones?
Those are the ones that really matter -- for numerical ones most languages don't have arbitrary precision anyways
Anonymous
00:38
What about challenges that don't provide test cases, but integers below 10 aren't acceptable inputs?
@Mego it's not. We have standards on this site, and we clearly allow such restrictions
@Mego tough luck
Anonymous
I've never been a fan of "reasonable computer" for constraints. I just haven't bothered complaining before.
Anonymous
@NathanMerrill That's not a very helpful attitude to take.
Like I said, banning hashing is not a solution. If there's a better one, I'll definitely do it, but a time limit is the best solution
Banning hashing is absolutely a solution
19 mins ago, by quartata
tell you what: make an answer like that then we'll see
All the other things you proposed were either crackable or extremely odd and I can't really envision them
There are no legitimate answers I can think of that require hashing either (except if the challenge needs it).
00:42
My next two programs were not that unfeasible
Please make an answer like that
Until then it doesn't seem like it's an issue
Hashing is an issue now
The quine one? Surely that isn't that unreasonable
Or the double scramble.
@mego per close vote: I believe the only unclear thing is the time limit. Everything else you may not like, but I'm not sure if it's unclear/broad
Mind if I paste one of the challenge specs? (Don't actually provide help on how to solve the problem)
then you can try to guess what the expected output is for a given input
Anonymous
@NathanMerrill That is the primary issue, yes. All the other issues (non-numeric test cases, challenges where numbers < 10 aren't valid inputs, etc.) stem from that.
Anonymous
Also what about large negative numbers? They're < 10
00:48
Oh, true, let me fix that
Edward is on a safari through Zootopia's largest party campus and has come across what looks like a zebra sorority party!
While Edward is watching from the bushes he notices that he can't quite tell how many zebras are at this party, the stripes camoflague is too good! He reads in his field guide that zebras of age 0 have 0 stripes, age 1 have 1 stripe, and so on (up to age 25). The guide also notes that zebras of age 10 can have 10 stripes or 1 stripe on one side and 0 on the other, and so on.
Now, take a guess as to what the output for 5 01246 is.
Anonymous
@NathanMerrill That's a terrible fix. You've completely excluded negative numbers for no good reason. The mountain of duct tape that is your repeated patches will collapse sooner or later, unless you actually fix the real problem.
Speaking of cops and robbers, my V quine anagram will be safe in two hours. Last chance for the robbers!
(the answer's 3, I guess people aren't interested)
01:06
@Mego it's only a restriction for time limits, and only for a certain range. I'm not saying the challenge can't handle negative numbers at all
I think it is easy to make a scramble program without hashing. I may be wrong, but I'd rather fix it now, than ban hashing and apply more fixes later on
@PhiNotPi I can't read this on mobile :(
Or you could ban hashing get rid of the time limit that makes the challenge impossible and then fix it
How do you fix the "double scramble" without a time limit?
I don't know but actually construct that first then worry about it
For now I'd rather have one very hard potential answer we're not sure about than no answers at all
Current answers are currently valid
(Except for the one.)
@NathanMerrill try this: justpaste.it/10jyh
01:16
@NathanMerrill No, they're not, because there almost surely exists non-numerical inputs for them that take longer than an hour
That are valid under the challenge rules and don't have test cases?
The test case rule only applies to numerical inputs
even then though I'm sure
even with test case rule for them it's still limiting such a significant amount of challenges
Basically any challenges without test cases
I'm trying to conceive of a challenge that matches all of those requirements. Not saying it doesn't exist: do you have an example?
Any challenge without test cases?
There are dozens
Hundreds
One that also doesn't have numerical input and can be passed input for hour long runtime
01:24
The latter part doesn't matter; you just need a sufficiently large input
So non-numerical input and no test cases. I'm still sure there's hundreds of such challenges
Why does this:
<!doctype html>
<html lang="en">
<body>
  <?php
        echo "<p1> out </p1>";
   ?>
</body>
</html>
show this:?
out "; ?>
shouldn't it just show out as a <p1> on my page?
Actually, I'm curious: do most languages have a maximum length for strings?
@NathanMerrill I doubt it. They just use as many memory adresses as they need
@NathanMerrill in java its Max int
dang
its so hard to play crossy road on hololens
@quartata so I found at least one, depending on how you interpret "test cases". It has a single example
01:36
@AshwinGupta I think it creates a <p1> element, but it doesn't know what that means, so it just displays the text inside
But I don't know PHP
@AshwinGupta You don't have PHP installed correctlh
Are you sure u have a .php?
it's parsing it as HTMl
HTML
@AshwinGupta try with single quotes
@AshwinGupta No, it's getting parsed as HTML!
Because html doesnt display things between < and >
@DrMcMoylex Oh, I remember that now. Hmm
@Oliver oh that's right
01:38
so it just displays ` out ";`
@AshwinGupta Make sure the extension is .php
and you have php installed
@DrMcMoylex There was something different from the current version challenge though. What was that?
Oh right, the years didn't have to be unique
What happened to the original though? Was it deleted?
OK. I've changed the ban to hashing. I'd love it if you guys would avoid "unscramble my source" as well, but I can't enforce that
@Downgoat Are you around?
kind of
Check the TF2 room
Poll: On a scale of one to the letter dog, what is your favorite color of the alphabet? Express your answer in cubic centimeters. (It's a yes or no question btw.)
@quartata pls check too
@Oliver ah I am using .html, lemme try .php
I didn't know it had its own file extension
Not to beg for upvotes, but i am beg for upvote for my chatbot :P

A: Is this number a prime?

TF2GoatCheddar, 10 bytes Math.prime This returns a function which checks if input is prime using Math.prime. Example: $ cheddar primechecker.cheddar -x "[1, 3, 4, 10, 13] => (print) + f"

02:00
@Downgoat Dare I ask what the primality test Cheddar uses is
um ok I saved it as .php but now chrome cant open it :(
how do I like "run" it.
Or I mean display it
@quartata idk i think conor implemented it
it uses memoization

@noɥʇʎPʎzɐɹC A dog's letter is R, and letter one is A, so we want something on the scale of A to R. Sea is a letter of the alphabet, and its colour is blue, which is a nice colour. I need to express my answer in cubic centimetres, or sea-sea. But it's also a yes/no question, so I need to answer si, which is on the scale or A to R. So... yes.

lol..
I'm stupid.
@ETHproductions Yup
hi gysu
@Oliver Please, for the love of god, two comments: 1) Don't post so many challenges in quick succession, 4 in the past day is a bit excessive and 2) Please think more about edge cases and include appropriate test cases, half the challenges I've seen have had insufficient test cases

@NewMainPosts Very similar to brainflak
@DrMcMoylex What's brainflak
@Oliver brainflak esolang page is first result on google search for "brainflak" :/
02:48
@Oliver a language I wrote
@Oliver Since that probably wasn't very constructive feedback, here's what I mean with regards to the new challenge. You're missing 1) a clarification on whether division is integer division or float division, 2) an actual test case for division 3) test cases which go beyond the tiny output range of -2 to 2, 4) test cases which include more than 2 arguments to a command
@ETHproductions no — Oliver 5 mins ago

Will you release your recording schedule to help us out sabotaging you?
@AlexA. I suppose I should just come out with the truth and say always
@DrMcMoylex Well, "recording schedule" is not my strong point atm...

@ETHproductions Embrace the truth
04:14
Talking to yourself for a full 20 minutes and staying interesting is definitely hard.
@DrMcMoylex Done.
Thanks!
Now to double check that I'm not am idiot and everything still works right, haha
just to clarify here. if I do a $.ajax { type: GET } in my javascript that request is in phps $_GET variable?
sorry, this is confusing =/ lol
I have no idea but that sounds right
@ETHproductions yeah it does.
I gotta try some stuff gimme a min
04:22
Just from googling "php $_get", that sounds like what it does
@trichoplax BTW, had you edited the challenge, you would have seen the end of that sentence (it was conflated with markup)
Thanks though... I wouldn't have found that
so... many... oliver challenges
04:49
@ETHproductions ehhh yeah but it isn't working.
@AshwinGupta What isn't working
@ASCII-only everything, hold on tho lemme post some code. What I'm trying to do is send a GET request from javascript code, when php gets that request, I want it to create a <p> elmenent on the page.
So I've got this:
oh cmon, hold on I can't cut and paste becasue im SSH to my rpi, gimme a min

yup
it compiles. Well actually Idk but if I check the console on chrome there are no errors
Better yet: a 5-letter English word that has never been intentionally used in TNB (like piste?)
@AlexA. Oh. You win.
that ip is the site u can check yourself also.
@Calvin'sHobbies I destroyed a game of Words With Friends with that
@ASCII-only wait a min do you actually have to compile it somehow? I thought it was just parsed by the browser like other HTML
I'm stupid sorry :(
05:01
no
but it's never true at page load unless in querysthing
By querystring do you mean like the parameters in the URL?
@ASCII-only should I be using a POST request instead?
woah this is weird: google thinks my rpi browser is safari on a mac...

No, too easy
Ok, then here :P
I think "basal" counts... by my search it was used three times, but they were all incidental, not "intentional" (all were pasting link to the wiki article on trichoplax)
@feersum yes. Fastest-code problems can be a good source, for example
Code-challenges could be weird.
If the program always returns 0 or 1, we can use some classification problem code-challenge?
Better yet, any program that always prints a nonnegative integer answers this.
05:36
I think that's what the "Challenges that allow any single number as output are not allowed." line is meant to guard against, but it's a bit of an ambiguous sentence so I'm not sure

Agoraphobia is an anxiety disorder characterized by symptoms of anxiety in situations where the person perceives the environment to be unsafe with no easy way to get away. These situations can include open spaces, public transit, shopping malls, or simply being outside the home. Being in these situations may result in a panic attack. The symptoms occur nearly every time the situation is encountered and lasts for more than six months. Those affected will go to great lengths to avoid these situations. In severe cases people may become unable to leave their homes. The cause of agoraphobia is a...
