Q: Regular users can indirectly delete feed bot messages

Once more, The Nineteenth Byte has uncovered an exceptionally obscure chat bug. We noticed that, apparently, a regular user managed to delete one of the feed messages in our chatroom. I think that link only works for mods, so here is a screenshot: It turns out that he didn't actually delete th...

quartata

@MartinBüttner Wow, that's really... strange...

> I suppose you could ask why anyone would edit a feed message to reply to another user in the first place, but at least in our chatroom that actually happens quite often, when an impatient user posts the same onebox as the bot a few minutes earlier. In that case, the mods usually delete or edit the bot post to remove the clutter from chat.

Q: Count Up Together

The goal of each answer is to output the integer that is one more than the previous answer's output. For example, if the previous answer's output was 5, your answer's output should be 6. Sounds simple, right? Here's the catch: you must output the next integer N, using at most N bytes of code. Th...

Testcases:

1, 2, 5

quartata

@NewMainPosts This seems too easy because of the number of languages with straight up number literals

Maybe if it was exactly that number of bytes

So 5 would have to be done in 5 bytes

Cyoce

Did you have King Arthur make your test cases again?

Martin Büttner

@quartata padding code is usually trivial too

quartata

@MartinBüttner Fair point :/

We'd have to do some code-bowling rule stuff

Martin Büttner

I don't know of any code bowling rules that actually work.

xnor

11:13 PM

Rule: Don't do code bowling.

J Atkin

@Cyoce Yep

He was really nice

And fast

Martin Büttner

@JAtkin I find the use of the Unicode character a bit unnecessary, when a simple underscore would suffice.

SuperJedi224

J Atkin

It looks a little ugly with just an underscore

That char is basically a wide hyphen

SuperJedi224

@MartinBüttner The unicode standard name is "LOW LINE".

Although I think underscore sounds better

J Atkin

11:17 PM

Just to clarify, you are saying it is too easy, right?

Martin Büttner

uhhh, am I?

quartata

> A single user may not post more than one submission in 8 hours.

Why?

@Mego pls

Martin Büttner

@quartata so that Mauris can't use up all the languages that exist in 20 minutes

quartata

@MartinBüttner He disallows back-to-back answers already..

This seems highly unnecessary.

Also, I'm very tempted to hammer this as too broad. There's millions of languages that can do this trivially.

@MartinBüttner I was thinking of @quartata

Martin Büttner

@quartata well then Mauris and jimmy could do that together...

quartata

@MartinBüttner I don't think Jimmy's around too much anymore, thankfully.

I'm more worried about you + Mauris

Martin Büttner

"thankfully" :(

jimmy's answers are amazing.

@quartata I considered posting an answer, but I really don't see the point.

El'endia Starman

Awww, almost had another not-mine post in Minkolang... :P

quartata

No, but I mean if he WAS around this challenge would be done by now

@El'endiaStarman Sorry :/

@MartinBüttner There really isn't. I know at least 20 languages that can do this in one/two bytes, and once you've gotten past the 20 byte mark you can basically use any language

> Too many possible answers

This is almost a textbook too broad, in my mind.

Also @El'endiaStarman you better let @Dennis know that the Minkolang interpreter on TIO is borked

My program wouldn't work on it :/

No output

minkolang.tryitonline.net/#code=NE4u&input=

El'endia Starman

11:23 PM

Well, I don't use the TIO interpreter, so I won't notice such issues.

Hrm. That is a problem.

quartata

I love how the Pyth answer gets an upvote just for being Pyth

I'm tempted to downvote it just to fix that

Martin Büttner

@quartata never counter-vote.

quartata

A jest

But I still don't understand why it got an upvote....

Martin Büttner

also the explanation is plain wrong

quartata

That too

Pyth doesn't have a stack...

Martin Büttner

11:29 PM

quartata

darn I got ninja'd to it

xnor

And I thought there would be no way to mess up explaining the program "4"

quartata

@MartinBüttner Link to the original sandbox post for this?

Martin Büttner

@ codegolf.stackexchange.com/questions/67438/… it does if you're willing to listen to it.

quartata

I honestly don't remember ever seen this

Martin Büttner

11:31 PM

it's at the top of the sandbox

(deleted though)

xnor

i missed it too

quartata

Apparently I had upvoted it...

Martin Büttner

:D

quartata

....I'm guessing I was drunk...? wat

ok

..

Anyways.

xnor

you know, i've often seen the situation where people post something that got sandboxed with negative comments, thinking it's fine

i think there's a communication gap where the poster reads it as a suggestion and the commenter is pointing out a serious problem

quartata

11:33 PM

I think it kinda stems from issues that are not worthy of a downvote but of a comment

xnor

and others upvote so it seems good to go overall

quartata

Then the poster sees the score and thinks "Oh this has no downvotes so it's good"

@xnor Yeah, exactly.

Maybe if we had a side-vote...

Martin Büttner

this is why I don't wait for or listen to upvotes on the sandbox posts, but actually wait for several people to see it and tell me it's good to go... (either in chat or via comments)

Anonymous

Hi guys

Martin Büttner

I guess there's also the thing where you value certain people's opinion more than others'

quartata

11:35 PM

@Mego I don't know if you saw, but pl did 2spooky4me in 12 bytes.

I think that's as low as it goes (hopefully)

xnor

maybe we should be more proactive with sandbox downvotes, using them for any significant problem, even if fixable, and removing it on edit

quartata

@xnor Possibly.

But the issue is that oftentimes people don't browse the Sandbox every day and forget to remove the downvote

Anonymous

No comments for 5 days after I fixed the issues that people pointed out and I agreed were issues implied (to me) that the challenge was good to go. I have a few ideas for how it can be fixed; I'm going to make edits.

quartata

Which makes things discouraging especially to new users

Anonymous

@xnor That's not how other people use sandbox downvotes?

xnor

11:37 PM

@quartata I was thinking the poster would ping the downvoter, which also helps with the problem "but I thought I fixed all the sandbox comments"

@Mego I haven't been. I just point out the issues, which looking back might not work that well.

Anonymous

Honestly I wish I could remove my upvote on the "yes" answer on the "Is the Sandbox useful" meta thread, because I've seen issues with it since I originally voted

Martin Büttner

@Mego I tend to use downvotes for proposals which I don't think are salvageable, which I really don't want to see on main, or which are underhanded

Anonymous

@MartinBüttner I really don't want to see poorly-spec'd challenges on main, so I downvote Sandbox posts that have issues, and comment on them (or upvote existing comments). When they're fixed, I go back and change my vote.

Martin Büttner

@Mego also, no offence, but I don't see how you addressed my comment or Peter's (and I admit that I didn't check back on your edits to see if the proposal had improved)

xnor

How often can someone think through a sandbox challenge and vouch for it "I believe this has no issues and is good to go"?

Anonymous

11:43 PM

@MartinBüttner None taken. Looking back, I should have added (and now will add) a scoring system, so that part of your comment was neglected by me. I still believe the main challenge for large N will be finding a language that hasn't already been used. As for Peter's comments, I disallowed newer languages like he suggested, but I don't want to open the can of worms by trying to precisely define an "integer literal".

xnor

(why are discussions about SSD's flagged offensive all of the sudden?!)

quartata

?

Martin Büttner

I think "finding a language that hasn't been used" is trivial if the task is trivial.

xnor

@quartata I just got 13 chat flag review popups for benign-looking messages about hard drive reads

Anonymous

@MartinBüttner Well, finding a language that hasn't been used that can answer in less than or equal to N bytes.

Martin Büttner

11:45 PM

@Mego right, but I don't think that's going to be an issue before you already have 200 bytes at your disposal.

quartata

Anyone know SEDE?

El'endia Starman

I've written a couple queries in SEDE.

Dec 15 at 1:46, by El'endia Starman

There's this too, written by a fellow SE mod: http://home.jtan.com/~cellio/sede/tutorial.html

Anonymous

@MartinBüttner Perhaps, but I think the most interesting part of this challenge is that the list of languages that can be used for an answer both grows and shrinks as N increases, rather than just strictly shrinking, like other answer-chaining challenges.

quartata

I want to make a query that returns all answers that don't have a line with # and byte or char

But I don't know if SEDE has regex :P

@El'endiaStarman Ah thanks I was looking for that

El'endia Starman

Well, SEDE uses SQL, so...

quartata

11:49 PM

:P

'Twas a joke.

Does the body of the answer have the Markdown source or HTML?

Anonymous

@quartata You can do it in pure SQL easily enough. Assuming table ANSWERS and column BODY, SELECT * FROM ANSWERS WHERE BODY LIKE "#%byte%";

But thanks

Anonymous

@quartata I can't read and type at the same time :P

quartata

I need to figure out if the "body" gotten from the query is in HTML or Markdown

El'endia Starman

@quartata I'm not sure, actually. I'd bet on the latter, though.

quartata

11:51 PM

Hmm

@El'endiaStarman Figures :P

Anonymous

^^^

El'endia Starman

Well, there exist queries that use content length, so you could probably use that trick to figure out whether bodies are HTML or Markdown.

Anonymous

Hmm... The 8-hour rule on my challenge... I included it so that a small group of users couldn't just cycle through the group and dominate the challenge, making it harder for other users to post answers.

quartata

> Invalid column name '#%byte%'.

Huh

Anonymous

I am open to shortening the time, though; I'm just not sure what would be better. 1 hour? 2?

quartata

11:55 PM

select * from posts where body like "<h%byte%"

What did I do wrong :/

And before you ask why I didn't uppercase the keywords

I'm lazy
