Is there a way to search through the comments posted on a challenge?

wizzwizz4

@seshoumara You could request the comments through the API.

seshoumara

@Mego I think you commented once something about the fact that this is code golf, we're not here to write portable code, or write according to best practices.

I'm trying to find that comment, does anyone remember it?

Anonymous

I could look through my comments

seshoumara

9:04 AM

thanks

wizzwizz4

@seshoumara +1 for technique, but could be golfed more.

It's a really efficient algorithm though.

O(1), if my calculations are correct.

seshoumara

@wizzwizz4 To what are you reffering?

Delegation.

seshoumara

:)

my only hope is if someone remembers it, as I don't know how to search comments

wizzwizz4

@seshoumara You could go though every comment ID. That's not too hard, though it could ~~bring~~ slow down the SE servers if you request them all at once.

seshoumara

9:07 AM

how?

wizzwizz4

@seshoumara Hover over a link to a comment in your inbox.

Look at the URL.

seshoumara

I only know to search using the search bar, and at type there's only is:question or is:answer

wizzwizz4

@seshoumara You'll have to write a custom script; the search bar doesn't do comments. :-/

seshoumara

yeap, exactly my problem, and I don't know any JS or web programming stuff

ASCII-only

We can use SEDE

wizzwizz4

9:10 AM

@ASCII-only Iirc that doesn't do comments... does it?!!

Anonymous

I haven't found that comment through searching back in my comment history through July

seshoumara

it's not that important either, if Mego doesn't find anything, then I leave it be

ok

Anonymous

It's entirely possible it was deleted at some point, either by me or by a mod

ASCII-only

@wizzwizz4 It has a comment DB, brb searching

seshoumara

@Mego I only guessed it was you, not sure actually

My C is rusty, but those calls to sizeof seem like they could be replaced by a magic number. Maybe it wouldn't be as portable, but hey--this is code golf. — DLosc May 6 '15 at 5:57

Yeah, I can't find the exact comment I remember. It must have gotten deleted.

seshoumara

just a fun comment

ASCII-only

@seshoumara just use SEDE

seshoumara

I am now.

wizzwizz4

@BassdropCumberwubwubwub Vote. Every day.

The system requires an action, not just a visit, so remember to vote.

Asking / answering also counts, but it's easiest to vote and ask / answer..

seshoumara

@ASCII-only thanks for that link, I didn't knew of SEDE, I thought one needs to write an independent JS, jQuerry stuff program. I'll remember it for my future search needs.

I ran the script and apparently a lot of users said that comment in one form or another :)

wizzwizz4

9:26 AM

@seshoumara Cite all of teh thingz.

Actually, you might go over the post length limit if you cite all of them.

seshoumara

it's a common thing to say to those new to PPCG and to golfing in particular. I was just about to do that myself, and that's how I remembered of one such comment some time ago.

Here are a few examples:

"Here at codegolf the main objective is not to use best practices, or to write beautiful, maintainable, or platform-independent code."

wizzwizz4

@seshoumara You can one-box them by providing comment links.

Jan Dvorak

Really? I thought beauty was among the goals...

wizzwizz4

@JanDvorak Beauty is subjective.

Jan Dvorak

we have popcons

wizzwizz4

9:30 AM

Some consider Q to be an ugly HQ9++ quine, but others don't.

ATaco

Grapher is online.

Jan Dvorak

According to the latest definition, it's not even a quine

wizzwizz4

@JanDvorak Shush... :-P

seshoumara

@wizzwizz4 that script provides no links to the comments

wizzwizz4

@seshoumara Add AS [comment link].

If that doesn't work, try AS [post link].

Bassdrop Cumberwubwubwub

9:42 AM

@wizzwizz4 Actually I barely ever vote, I lurk more.. I usually look at a few posts, then get back to work, then back to ppcg etc etc. Apparently that's enough for the system to register my activity

wizzwizz4

@BassdropCumberwubwubwub Oh. Perhaps it's just a homepage view that it doesn't count.

seshoumara

@wizzwizz4 and how do I get to the actual comment with the number 6625?

ASCII-only

@wizzwizz4 It counts homepage views for me

wizzwizz4

@ASCII-only Huh. I read somewhere (mSE?) that homepage views didn't count.

-.(o.o).-

If it's a bug, it works in our favour! ;-)

ASCII-only

well at least I think so

wat

Erik the Outgolfer

@JanDvorak That challenges can't be sandboxed, so an increase of bugged challenges that could have been salvaged by posting in the Sandbox first.

i.e. damage on main

ASCII-only

@seshoumara yeah (T-SQL)

Jan Dvorak

9:59 AM

@EriktheOutgolfer I think you're exaggerating.

Erik the Outgolfer

@JanDvorak Exaggeration lowered.

flawr

Did we already have a challenge about heaps?

Jan Dvorak

lowering taken :-)

ASCII-only

@seshoumara btw this works (btw the autolinking isn't part of t-sql :P)

data.stackexchange.com/help

Erik the Outgolfer

@flawr That means that whoever has posted a catalog on main is also a jerk???

flawr

10:08 AM

I'm not sure what to say, because IIRC this includes me XD

ps anyone familiar with heaps?

ASCII-only

@ConorO'Brien D: you forgot about this week's tetralingual tuesday

@flawr nope reads post i'm a bit familiar now :P

it seems like sorting -> turning into a tree would work?

Erik the Outgolfer

I don't think so.

ASCII-only

@EriktheOutgolfer When would it not work

Erik the Outgolfer

Oh wait, I wasn't thinking out of the box.

So, something like this pseudocode would work: (x)->turn_into_tree(sort(x))

Except that if the language isn't called Mathematica it's highly unlikely there would be a turn_into_tree built-in.

Jan Dvorak

so, sort backwards and call it a day?

ASCII-only

10:17 AM

@JanDvorak or forwards

Erik the Outgolfer

I have thought of something.

But it involves exponents. Anyways, here it is:

First, take a list x

Then sort x.

Then, group the elements of x in chunks of consecutive powers of 2 starting from 0, e.g. if sorted x is [1,2,6,7,9,11,50,5000] it would turn into [[1],[2,6],[7,9,11,50],[5000]].

ASCII-only

wait a second, output is a list

Erik the Outgolfer

I didn't finish.

ASCII-only

then wouldn't be any sort command be a valid solution? e.g. sorted in python

Erik the Outgolfer

You join by spaces then newlines, like this:

ASCII-only

10:23 AM

@flawr What format is the output in

Erik the Outgolfer

Of course, a more valid solution would be to really turn into a tree, like this: [1,[2,[7,[5000],9],6,[11,50]]]

flawr

11:53 AM

@ASCII-only ah right, that totally defeats this challenge, thanks=)

@ASCII-only should again be a list.

@EriktheOutgolfer many languages unfortunately do not support that kind of mixed lists

ASCII-only

@flawr Yeah I wasn't sure because it seemed too easy haha

@flawr Many of those that don't support mixed lists support custom datatypes though

flawr

Which add a lot of unnecessary bytes=)

Erik the Outgolfer

^ That's not your problem.

flawr

anyway, I'm trying to come up with a new heap-based challenge

@EriktheOutgolfer but what if I want to participate too? :D

Erik the Outgolfer

That's not in the scope of this discussion rn. We are discussing about the question, as well as language support. We aren't discussing about the answerers.

And yeah, if Jelly's Ṣ is a valid answer, the challenge is pretty much defeated.

ais523

huh, have the oneboxes for posts on Stack Exchange sites changed formatting?

Okx

i think so, yeah

Jan Dvorak

Seems the same to me

ais523

err, I mean posts on the sites

Erik the Outgolfer

@JanDvorak ais523 means that the sandbox formatting has changed.

ASCII-only

12:36 PM

@ais523 No, that's just what happens if SE tries to onebox a deleted post

ais523

@EriktheOutgolfer I checked the flags, it's a "primarily opinion-based" flag

which I guess is technically an accurate description? I don't think we should really be using those flags on Meta though

@ASCII-only oh, in that case we should probably unstar the post

Erik the Outgolfer

@ais523 That case has been already reviewed by me and flawr.

user165474

@ais523 Removed my star.

Jan Dvorak

Nah, if we were to close the sandbox, the best choice is clearly too broad

ais523

well, it's broad, but is it too broad? I think it's exactly broad enough to fulfil its function

Jan Dvorak

12:38 PM

There are far too many possible answers...

Erik the Outgolfer

@ais523 Wait a sec, that post has never been deleted!

ais523

let me onebox something to see how it looks now

codegolf.stackexchange.com/a/116363/62131

wait, did that not onebox at all?

user165474

Nope. >_>

ais523

let me try again

user165474

codegolf.meta.stackexchange.com/a/12048/42649

ais523

12:41 PM

codegolf.stackexchange.com/a/116363

that's not a deleted post though

user165474

It's not oneboxing anything >_>

user165474

But yeah, any final thoughts on this before I post? codegolf.meta.stackexchange.com/a/12048/42649

ais523

maybe oneboxing is just broken right now

Jan Dvorak

\o/

SOCVR is taking over the chat

Erik the Outgolfer

What?

Jan Dvorak

12:45 PM

Seems they have disabled oneboxes

Erik the Outgolfer

And why are we accusing SOCVR?

Jan Dvorak

I think they're the first ones that forbid oneboxes in their room

ais523

you know, I really wouldn't be opposed to a ban on oneboxes

they take up a lot of space, and so if they aren't relevant to the conversation you're interested in, they're really distracting

Jan Dvorak

I'd vote for their ban, actually

ais523

(especially because maybe ~50% of the oneboxes in TNB are somewhat offtopic anyway)

user165474

12:49 PM

What's SOCVR

Geobits

Some are distracting, sure. Amazon, usually Wikipedia, etc. Q/A oneboxes are nice, and usually relevant.

ais523

images are often offtopic, although I guess those aren't technically oneboxes

Geobits

It's a bit odd that it doesn't seem to have been mentioned on Meta (yet) though, if they've actually just turned them off.

Jan Dvorak

@HyperNeutrino ` chat.stackoverflow.com/rooms/41570/so-close-vote-reviewers

user165474

Okay. Thanks.

wizzwizz4

12:50 PM

Not turned off.

ais523

I imagine close vote review involves a very large number of links to posts and/or reviews, and oneboxing all of them would likely be overkill

Geobits

Probably. In a normal chatroom it's better to onebox them imo, since there's no way to know what post it is without clicking through otherwise.

I don't generally memorize post numbers, at least.

ais523

on most (non-SE) chat systems I've been on, it's usual to give a description of a link if you want people to follow it

and SE chat markdown even lets you put a link behind a particular word

Geobits

Yeah. Oneboxing is a nice shortcut imo. They could generally be a bit smaller though.

user165474

It's annoying when a deleted/closed challenge is oneboxed

Geobits

12:54 PM

And wikipedia oneboxes are just way too big.

user165474

Wait, this chatroom has wikipedia oneboxes?

wizzwizz4

@HyperNeutrino Don't try.

Geobits

I think all of them do by default.

(so the chat sandbox would be a good place to chek it out)

user165474

Okay. Thanks.

ais523

when a Wikipedia post is sufficiently relevant to the conversation (i.e. everyone participating would need to look at the article), oneboxing it would arguably make sense; that just doesn't happen very often

user165474

12:58 PM

@ais523 I agree. Is there a way to post a link without it getting oneboxed?

Geobits

Sure, but i still don't think it needs to include the first 6/7 lines of text.

It won't get oneboxed as long as it's not a bare link.

wizzwizz4

@HyperNeutrino Type a description

Or include a bit of text next to it: example.com

user165474

Oh.

user165474

*facepalm*

ais523

@HyperNeutrino just put any non-link text on the line: en.wikipedia.org/wiki/Code_golf; or give a link description: Code golf on Wikipedia

user165474

12:59 PM

Okay

user165474

Yay.

wizzwizz4

@Geobits You can't just delete when you've been ninja'd! :-)

Geobits

Apparently I can ;)

wizzwizz4

@Geobits That's a technicality.

ais523

I picked a link that actually would onebox, as a demonstration, so I'm not sure if it technically counts as being ninja'd

even though all the content was in wizzwizz4's post

wizzwizz4

1:00 PM

@ais523 You could argue that yours doesn't... But Geobits' was definitely one. :-D

Geobits

Well mine was a boxable link too, so there :P

wizzwizz4

@Geobits You have no proof.

user165474

So ais523 was ghost-ninja'd by Geobits

Geobits

@wizzwizz4 Well I can still see the history, so I could screenshot it, but it's definitely not worth that. Besides, you're a mod, and can see it for yourself. If you don't want to look, that's up to you ;)

Erik the Outgolfer

@Geobits wizz often likes to disprove you.

wizzwizz4

1:09 PM

@EriktheOutgolfer I like to try.

But I know when I'm beaten.

user165474

Question: Can mods/chat mods see deleted messages and can they see revision histories for chat messages?

wizzwizz4

@HyperNeutrino Yes and yes.

user165474

Okay. Thanks.

user165474

oh wow I got a rep change on stack overflow for the first time in a few months >_>

Poke

Just had a person contact me asking me to message someone who owns a misbehaving service... They own the service...

user165474

1:13 PM

@Poke Are they aware of that?

Poke

I sure hope so... They drew red lines with mspaint under the requested url

wizzwizz4

@Poke Pretend that you didn't notice.

Poke

Maybe it's the hosting infrastructure... I hope it is anyway

wizzwizz4

Write a formal message to them with their name, etc. describing what the message should.

Poke

@wizzwizz4 Like just tag them on the issue and ignore that it's the same person?

haha

wizzwizz4

1:14 PM

@Poke Yes. See how long it takes them to notice. >:-)

user165474

hah

user165474

wow ^

Poke

That's pretty devious

user165474

Pretend you didn't notice.

wizzwizz4

@Poke Then you've got a paper trail if they complain.

Yes, you did message the person who owned the service.

Here's the relevant log. Evidence.

(Although paper trails are best done on paper.)

user165474

1:18 PM

@wizzwizz4 Really? I thought paper trails were done best on a chalkboard.

wizzwizz4

@HyperNeutrino Some people get an email instruction, do the thing, get sued, then find that the email doesn't hold up as evidence.

ianal, but better safe than sorry.

user165474

I suppose, yeah that's a good point

wizzwizz4

Even worse is people who get a verbal instruction.

user165474

Oh yeah... there's practically no way to prove that.

wizzwizz4

@HyperNeutrino And if you try, you can be sued for unauthorised recording.

(Of course, you shouldn't be recording anyway...)

Geobits

1:30 PM

Wait, you guys don't have a recording of everything that happens at work? Weird.

Erik the Outgolfer

Wait, we are not all Geobits? Weird...

wizzwizz4

@Geobits Iirc in some parts of the US it's illegal.

Poke

@EriktheOutgolfer Not all of us can be robots. Then we'd have no one to learn from

wizzwizz4

@Poke Unsupervised learning?

Anyway, most bot tasks are communicating with humans.

Erik the Outgolfer

At least downvotearchy doesn't ensue...

wizzwizz4

1:34 PM

Humans don't even conform to standards!

Poke

@wizzwizz4 Robots learning from other robots is a recipe for disaster.

wizzwizz4

@Poke That's not what unsupervised learning means.

Erik the Outgolfer

Then what does it mean?

Geobits

@wizzwizz4 Oh I don't mean I'm doing the recording. The Company does it, both video and audio.

wizzwizz4

@Geobits That makes lots of sense.

It's quite sensible, really.

Erik the Outgolfer

1:35 PM

Oh, then the star on my message should be retracted.

wizzwizz4

You know who reprogrammed the bots to like removing things.

Geobits

@wizzwizz4 Especially when you work somewhere that makes/stores explosives and munitions ;)

user165474

Geobits -> Geobots? Maybe a typo? ‮

user165474

hehe i broke the starboard >_>

Erik the Outgolfer

Blame it on Geobits.

Geobits

1:40 PM

Not a typo. It used to be Geobot, singular.

But the bot broke into bits, and here we are.

user165474

Theory confirmed.

Kritixi Lithos

So you're saying that you're old

Geobits

I'm not sure how that follows at all.

Poke

@HyperNeutrino do you have a rtl override character in your name just in case you hit the starboard >.<

Kritixi Lithos

Bot => becomes old => so breaks into bits => Bits

user165474

1:43 PM

@Poke I accidentally pasted an RLO at the end of my message because you know, everyone keeps those on their clipboard for no reason. But no that's not allowed, I tried but it's not allowed :( and if you observe, I have 3 messages on the starboard right now

Geobits

@KritixiLithos No, Gears of War broke it, not age. Before GoW came out I never had an issue using the name. Then all of a sudden it was taken everywhere.

Poke

oh yeah... i'm a dumb

user165474

lol

user165474

yeah you can't have characters that aren't alphanumeric, spaces, or underscores

Erik the Outgolfer

> everyone keeps those on their clipboard for no reason.

Any references?

Geobits

1:47 PM

What sort of reference would convince you? Testimonials? Because I do ;)

user165474

@EriktheOutgolfer No... I don't think normal people do. (sorry @Geobits, you're not a normal person according to me :P))

Poke

i think that was hyperbole

Erik the Outgolfer

@HyperNeutrino It isn't Geobits who had that character on their clipboard though, it was you.

Poke

@HyperNeutrino what about a Nermal person

user165474

@EriktheOutgolfer But he gave a testimonial (i think?)

Poke

1:49 PM

you know the other cat from Garfield

user165474
