If you insert it correctly, you can make people think their keyboard is wrong

@MarsUltor What does that do?

Leaky Nun

Pinging does not work?

Did you receive my ping

Mars Ultor

@Bálint replace a character with character + one or more zero-width space

@LeakyNun ?

@MarsUltor That's evil

Eᴀsᴛᴇʀʟʏ Iʀᴋ

2:01 PM

Bálint

Evil on a whole new level

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@LeakyNun NO STEALTH PING

Leaky Nun

It doesn't work?

‌‌

Bálint

@EᴀsᴛᴇʀʟʏIʀᴋ Stealth pinging was corrected

Some time ago

Leaky Nun

How about this

http://testing.com/@EᴀsᴛᴇʀʟʏIʀᴋ

Eᴀsᴛᴇʀʟʏ Iʀᴋ

2:02 PM

that pings, but isn't stealth

@Bálint yeah

Leaky Nun

which one pings?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

but still disallowed to annoyingly ping.

Bálint

The other really really evil thing is to change spaces to hard spaces in some languages, wich doesn't support it

Zgarb

Chat mini-challenge: You're given a string consisting of the characters -<>. The pairs --, -<, ><, >-, <> are linked, and the remaining pairs ->, >>, <-, << are not. Your task is to split the string at the middle of each non-linked pair. For example, "-<>>->--<>-<<>--<" gives output "-<>", ">-", ">--<>-<", "<>--<".

Martin Büttner

@Zgarb This sounds quite fun for a proper challenge. :)

Pure evilness

Anybody willing to give a Meta.SE bounty?

for at least 100 rep.

Bálint

@LeakyNun how do you use it?

Leaky Nun

1. Click "Run Program! (Ctrl-Enter)"
2. Copy the result.
3. Paste it in some text editor.
4. Try to delete it by backspace.
5. ???
6. Profit!

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Bálint

1000 zws-s?

Leaky Nun

2:08 PM

yep

Eᴀsᴛᴇʀʟʏ Iʀᴋ

you can't send the message

Martin Büttner

@Zgarb Retina, 29 but I think it should be possible in less...

Eᴀsᴛᴇʀʟʏ Iʀᴋ

500 char is the limit

Zgarb

@MartinBüttner Maybe... I thought it would be very simple with reasonable regex tools.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

yeah, doesn't ping anymore

Bálint

2:10 PM

What is the best IDE for HTML, CSS and web languages?

Angelfire

Retina, 25

@MartinBüttner 22

@LeakyNun I was just about to post retina.tryitonline.net/…

Leaky Nun

It keeps getting better...

Martin Büttner

2:16 PM

hm wait

that wasn't quite correct

oh but this is for 13: retina.tryitonline.net/…

Eᴀsᴛᴇʀʟʏ Iʀᴋ

damn, that's short

Downgoat

@Bálint vim

Poke

@Bálint some people seem to like WebStorm

sublimetext is a decent all purpose editor

Bálint

@Poke I don't have a credit card to actually pay for it (yet).

Downgoat

@Bálint or brackets

Zgarb

2:19 PM

@MartinBüttner How does that work?

TimmyD

@Bálint notepad.exe

Nathan Merrill

@Bálint WebStorm

Bálint

@TimmyD I'm not stupid, nor masichist

@NathanMerrill I don't have a credit card to actually pay for it (yet).

Nathan Merrill

are you in school?

El'endia Starman

I dunno about the best, but I use Notepad++.

Bálint

2:20 PM

@NathanMerrill No, but I can't have one until I'm 16 and I can work

So, until tomorrow pretty much...

Martin Büttner

@Zgarb Well, a valid chain can only consist of matched <> or hyphens, because everything else breaks it. The only unmatched > or < can be at the start or end respectively. So I'm just matching that form directly instead of checking for all pairs character by character.

2

Nathan Merrill

wait, you aren't 16, and you aren't in school?

TimmyD

Martin Büttner

I've basically converted the problem to an NFA and converted that NFA to a regex (very informally)

Bálint

@El'endiaStarman I use it too, but I want to look for a better one

@NathanMerrill It's 4 PM here

Martin Büttner

2:21 PM

@NathanMerrill time zones...

Zgarb

@MartinBüttner Ahh, that's clever.

Martin Büttner

thanks :)

Nathan Merrill

@Bálint lol, I mean are you attending a school :) JetBrains has a educational license

Bálint

@NathanMerrill Isn't that for university students?

Poke

you could use eclipse :]

>.<

Downgoat

2:23 PM

@Bálint my school doesn't sanatize their inputs either .-.

Zgarb

And !` means "remove matching prefixes greedily, printing one per line"?

Martin Büttner

@Zgarb it just means "print all matches" (one per line)

Bálint

@Poke Eclipse is for java mainly, and I hate eclipse

Poke

eclipse is like emacs

just a nice ocean of plugins

you can do everything with it

Martin Büttner

@Zgarb if you would put a ; in the input, then it would break the chain but not appear in the output at all

Zgarb

2:24 PM

@MartinBüttner Oh right, because matches will naturally be a partition of the input.

Martin Büttner

yes

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I'm thinking of doing a challenge that requires printing the decimal expansion of 1/49...9 to K digits, like, given n = 3 and K = 6, print the first 6 digits of 1/4999

Eᴀsᴛᴇʀʟʏ Iʀᴋ

okay?

Martin Büttner

@CᴏɴᴏʀO'Bʀɪᴇɴ I think we've had that for 99998 iirc

Eᴀsᴛᴇʀʟʏ Iʀᴋ

oh

Bálint

2:25 PM

> Sublime Text may be downloaded and evaluated for free, however a license must be purchased for continued use. There is currently no enforced time limit for the evaluation.

That's like winrar

Nathan Merrill

@Bálint not necessarily, but you will need an edu address or an ISIC card, or for your high school to get a Classroom License

Leaky Nun

@CᴏɴᴏʀO'Bʀɪᴇɴ Related

Martin Büttner

maybe not though... can't find it

Bálint

@NathanMerrill I can guarantee, I have none of those, because I have no idea what those are

El'endia Starman

@Bálint Yes, though I think Sublime looks for stuff like how often you save a file, or how much text you type, that sort of thing. So it's a usage limit, not a time limit.

Nathan Merrill

2:26 PM

the first is an email address, the second you can obtain for $25

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@LeakyNun kinda not really

TimmyD

@CᴏɴᴏʀO'Bʀɪᴇɴ Related

Nathan Merrill

petitioning your school for a classroom license is free, though not guaranteed :)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@TimmyD true, but this would probably be better solved using a different approach

Katenkyo

Hum, the obfuscating challenge has been putted on hold while I was finishing my clean code D:

I'm sad now :'(

Nathan Merrill

2:31 PM

even if it wasn't off topic, it would be a duplicate of this challenge:

95

Q: Obfuscated Hello World

Create the shortest possible obfuscated program that displays the text "Hello World". In order to be considered an obfuscated program, it must meet at least two of the following requirements: Does not contain the characters: "h", "l", "w" and "d" in any case Does not contain the characters...

which should be closed IMO

Katenkyo

I don't see how it is a duplicate, and also it isn't closed as off-topic, but too broad ;)

Leaky Nun

@Zgarb Any J challenge?

Nathan Merrill

er yeah, I mean too broad

I think I voted it too broad anyways

Zgarb

@LeakyNun Are you learning J?

Leaky Nun

@Zgarb Yep.

Nathan Merrill

2:35 PM

they are duplicates because the core of the challenge "obfuscate" is essentially the same

the different task is irrelevant

Katenkyo

@NathanMerrill that's the same as saying two string processing challenges are the same because you have to string-process in both...

Nathan Merrill

and the additional restrictions (that the particular letters can't appear in your source code) could be grounds for differentiation, but it isn't big enough IMO

no, its not. Obfuscating is the task, not the type of task

where as string processing is the type

otherwise, we could take every challenge on our site and make it an obfuscation challenge

Leaky Nun

Chat mini-challenge: four-square conjecture (I know it's a duplicate so what)

Zgarb

@LeakyNun Alright. Task: given a 2D array of integers (of size at least 2x2), find the 2x2 sub-array whose sum is maximal.

Katenkyo

@NathanMerrill Obfuscation is the criteria which defines the voting guide line (the "quality" of each submissions) in a popcon, it isn't a task

Leaky Nun

2:37 PM

@Zgarb testcase?

Nathan Merrill

what is the "core" of the challenge?

people aren't trying to figure out how to write a hello world, they are trying to figure out how to obfuscate

Katenkyo

@NathanMerrill I agree that the core of the challenge is the obfucation, but the task is simply comparing an input to your username.

Nathan Merrill

so are you ok with somebody making an obfuscation challenge out of every other challenge on our site?

Katenkyo

@NathanMerrill That could be the same in any other popcon, they don't try to output hello world, they try to output the most beautiful hello world

Zgarb

Input:
3 12  4 4
5  0  1 9
2 10 11 0
Output:
 0  1
10 11

@LeakyNun ^

Nathan Merrill

2:40 PM

@Katenkyo right, and if we had 2 popcons that were both "make the code as beautiful as possible", one would be a duplicate of the other

Katenkyo

@NathanMerrill No, I'm not, obfuscation, as other popcon, must not be something that copycat every other challenges for the sake of a different winning criteria

Poke

i like popcorn

Leaky Nun

@Zgarb thanks

Nathan Merrill

@Katenkyo we allow copying of challenges under a different scoring criteria, as long as answers in the other challenge aren't competitive

Katenkyo

@NathanMerrill popcon judges mostly the output and the algorythm, not the code in itself, so yes, it's the goal

Okay, maybe I'll give you something simpler.
