@mınxomaτ You didn't finish listening >_>

What?

zʏᴀʙiɴ101

When the server gets a request, it responds with a status 200 response, with text/plain as the Content-Type and response body Hello, World!

Node.js, 147 bytes:

var h=require("http");h.createServer(function(q,a){a.writeHead(200,{"Content-Type":"text/plain"});a.write("Hello, World!");a.end();}).listen(8932);

mınxomaτ

That's exactly what my bash code does. Also you didn't say anything about the content type.

I have a mini (not really) -challenge: Create a Regular Expression that will only match near-perfect English sentences (i.e. those with completely correct spelling based on the dictionary, follows english syntax, commas in right place, sentences start with capitals and end with periods, etc.)

Leaky Nun

@R.Kap define perfect

@R.Kap This is a very hard challenge. You might want to promote it to an actual challenge and put it in the Sandbox.

Today I discovered

Retina

Discussion about the Retina programming language, including us...

There is a room for Retina? o_O

R. Kap

@zʏᴀʙiɴ101 Seriously? I work for hours on I challenge I posted in sandbox several hours ago, and now a challenge I think of on the spot in less than 5 minutes should be an actual challenge? Okay then...

zʏᴀʙiɴ101

@R.Kap It's a very hard challenge.

There is a reason to promote it.

thepiercingarrow

@LeakyNun Ah I see. Very good you passed all 10 test cases good job!!!!

@LeakyNun You are a GENIUS

Leaky Nun

@thepiercingarrow thanks, lol

R. Kap

@zʏᴀʙiɴ101 I have a feeling that most people won't like that...I made a pretty hard challenge a while ago, and it was not answered much...

@thepiercingarrow Any more challenges?

thepiercingarrow

9:09 AM

@R.Kap Yeah.

Leaky Nun

@thepiercingarrow +1

thepiercingarrow

Another usaco one?

R. Kap

@thepiercingarrow Yeah, sure

Leaky Nun

@thepiercingarrow try to make one yourself ^^

thepiercingarrow

@R.Kap btw yeah I can parse strings with regular expressions

R. Kap

9:11 AM

@zʏᴀʙiɴ101 So you are saying that this regular expression challenge I made up on the spot is better than this one in the sandbox?

zʏᴀʙiɴ101

@R.Kap They are equally good. I didn't mean that the regex challenge is better.

Has there been a problem to generate the smallest string which contains all the permutations of ~~an alphabet~~ a set?

R. Kap

@zʏᴀʙiɴ101 Oh, okay then. What do you think of my challenge in the sandbox by the way?

Leaky Nun

@nhahtdh .p

@R.Kap Good

thepiercingarrow

9:13 AM

Okay here's a fun challenge I made up:

nhahtdh

@LeakyNun No, not really

Leaky Nun

@nhahtdh oh, I think there is

R. Kap

@zʏᴀʙiɴ101 Do you think it should it be a fastest-code challenge or a simple code-golf one?

Leaky Nun

it's got a special name

and the challenge uses that name

thepiercingarrow

There are anti-communist marchers in HK right now (tomorrow is CRC birthday so they are protesting).

Leaky Nun

9:14 AM

but I forgot what the name is

@LeakyNun I see. I'm reading the wikipedia article right now.

@zʏᴀʙiɴ101 Nice. I heard russians are good at everything.

R. Kap

9:18 AM

@zʏᴀʙiɴ101 Ah, I see. That's cool. How's everything going over there?

thepiercingarrow

There are anti-communist marchers in HK right now (tomorrow is CRC birthday so they are protesting). true story. They are loud as hell right outside my window (I'm staying in HK for a month). Literally every policeman in the goddamn city is on duty right now. There are 4 main groups of marchers: the band, the drummers/dancers, poster carriers, and flag holders.

Leaky Nun

@nhahtdh there must be a special name

it starts with B

but I forgot the name

R. Kap

@thepiercingarrow Well, I would not say the best at everything...

Leaky Nun

@thepiercingarrow which part?

R. Kap

Flag holders (F) can march anywhere, but two flag holders cannot march next to each other, unless three or more flag holders are together.

Leaky Nun

@thepiercingarrow what is the challenge?

7 mins ago, by thepiercingarrow

Okay here's a fun challenge I made up:

thepiercingarrow

The band (B), consisting of N people, has to be together, surrounded by flag holders. The poster carriers have to be behind the band (all together, or in two groups).

nhahtdh

Found it codegolf.stackexchange.com/questions/42728/… (via deleted:yes on meta, yay)

thepiercingarrow

There are M total people (the rest are policemen (P)).

@nhahtdh Nice :)

@LeakyNun This is the challenge.

Leaky Nun

oh ok

zʏᴀʙiɴ101

9:23 AM

But the question is?

Leaky Nun

@nhahtdh ahhh... de brujin came to my mind

thepiercingarrow

Given the number of flag holders, poster carriers, band members, and total people, print one line for every possible configuration, organized in alphabetical order.

zʏᴀʙiɴ101

What to do?

Leaky Nun

but I dismissed it as de brujin index

@thepiercingarrow testcase please

R. Kap

@thepiercingarrow Whoa, nice challenge.

thepiercingarrow

9:24 AM

@LeakyNun Making one right now...

@R.Kap thx

R. Kap

+1 imaginary point

thepiercingarrow

Here is the entire thing:

There are protesting marchers marching through a city. There are 4 main groups of marchers: the band, the drummers/dancers, poster carriers, and flag holders. Also, every policeman in the whole city is on duty.
Flag holders (F) can march anywhere, but two flag holders cannot march next to each other, unless three or more flag holders are together.
The band (B) has to be together, surrounded by flag holders. The poster carriers (C) have to be behind the band (all together, or in two groups).

Given the number of flag holders, poster carriers, band members, and total people separated by your …

Hm.. is this problem quality enough to post on the main site?

R. Kap

@thepiercingarrow Wait, how can 3 or more flag holders be together if no more than 2 flag holders can march next to each other?

Leaky Nun

Post a testcase here, lol

thepiercingarrow

@R.Kap That is the excepcion. Two can't march unless there are three or more.

R. Kap

9:27 AM

@thepiercingarrow Did you just come up with this on the spot?

thepiercingarrow

@R.Kap Yup.

@R.Kap generate all permutations, filter for string which do not match B.*C and which do not have 2B when run-length encoded

R. Kap

@LeakyNun But you literally coded it in a matter of minutes...

Leaky Nun

lol

zʏᴀʙiɴ101

It takes a knowledge of Pyth and quick fingers. With these, you don't have to type 100 keystrokes to do it.

R. Kap

@LeakyNun Won't that get incredibly slow as the total number of people increases exponentially?

Katenkyo

9:47 AM

@R.Kap Habits, and a really short language ^^

Leaky Nun

@R.Kap yes

zʏᴀʙiɴ101

Instead, it takes you a few mins to code a challenge.

R. Kap

@LeakyNun Isn't there a better way to do it?

Leaky Nun

@R.Kap sure

Katenkyo

@R.Kap But we only look at the size for codegolf, not the complexity ^^

Even if it would need to run until the dawn of the universe, it's fine as long as we saved 1 more byte

R. Kap

9:49 AM

Well, in that case, this would be a better challenge suited for fastest-code rather than code-golf.

It would definitely add more of a challenge to it.

Katenkyo

@mınxomaτ neat

Would have rekt Jelly if had I recoded everything in Prolog earlier :(

sanchises

@R.Kap I was just writing a comment about it, which may be helpful for you when writing further challenges. I think the main problem was that it was a lot of different challenges packed into one, most of which were a variant on Do X without Y. They are generally not well received - indeed, most challenges strive to have an input and output format as easy as possible.

R. Kap

@sanchises How do you think it can be improved?

Maybe allowing the use of built-in sin/cos functions?

@sanchises It's undeleted now, by the way.

sanchises

@R.Kap Honestly? I think it's just not that great a challenge. But perhaps you can take a single part of your challenge, like this one did. Perhaps make an interesting challenge about graphing trig functions? Although I wouldn't know how one could make that interesting since that would be trivial in some languages with built-in graphing capabilities, and extremely tedious in others.

You could go for a kolmogorov-complexity-like one and require an ASCII output with a sine wave with different symbols based on the line slope (-,|,/,) and an axis system?

thepiercingarrow

10:56 AM

@R.Kap I believe you register online at usaco.org

And either ways make your challenge focused on only one aspect, so don't require complicated parsing and support for all trig functions you know and their inverses and ... etc.

@flawr well, technically main, alright?

flawr

You mean the accounts you use most?

@el'endia I endured my index fingers and Right and + keys in solving problem sixteen.

But I solved it.

now I share 4 problems with 5 friends and 3 with 3 friends.

El'endia Starman

Problem 16, huh? Hah, summing the digits of 2^1000 certainly would've been harder before bignum libraries were a thing.

flawr

Make your own bignum libraries?=)

Endured these again in solving problem twenty.

But I solved it.

flawr

@zʏᴀʙiɴ101 Go for 312!

El'endia Starman

@flawr I remember reading in some forum thread that that actually was the point of those problems.

Fatalize

@El'endiaStarman Is the answer 1366?

El'endia Starman

Of course, technology marches on, and 14 years later, built-in bignum capabilities are a common sight... :P

TimmyD

@zʏᴀʙiɴ101 What do you mean by "endured" in this sentence?

@TimmyD I repeatedly tapped Right then + then Right then +... with my index fingers until I finished the equation.

@zʏᴀʙiɴ101 ...there are so many better ways to do that... :P

zʏᴀʙiɴ101

I didn't find any :P

@zʏᴀʙiɴ101 REGEX! XD

El'endia Starman

>>> for digit in str(2**16): print(digit,"+",)

6 + 5 + 5 + 3 + 6 +

Then copy-paste (without including the last +) and hit enter again.

@TimmyD I don't PowerShell, sorry.

CMC: the sum of the first 10 digits after the decimal point of pi is 1+4+1+5+9+2+6+5+3+5 = 41.

Determine the sum of the first 1000 digits after the decimal point of pi.

TimmyD

@zʏᴀʙiɴ101 You should - it's great and does all things.

zʏᴀʙiɴ101

I can't have PowerShell on my home computer. >_>

It has Vista, and I need an upgrade of the computer to get 10 working on it.

(CMC = ComputerMathChallenge.)

El'endia Starman

I thought it was Chat Mini Challenge...

zʏᴀʙiɴ101

It is, too.

TimmyD

1:50 PM

@zʏᴀʙiɴ101 PowerShell v2 runs on Vista SP1

El'endia Starman

But anyway, what tool or programming language are you using to solve PE problems, @zʏᴀʙiɴ101?

zʏᴀʙiɴ101

@El'endiaStarman Python (see my profile).

If being exact, Python 2.7.10.

El'endia Starman

You definitely could've done PE #16 less arduously. :P

@zʏᴀʙiɴ101 mon, 2.7.12 is out

gotta get those new features, man

@Poke They arise for different reasons, though.

Also, Benford's law applies to continuous data, while Zipf's law applies to categorical data.

Poke

I would accept the argument that my statement about benfords being a corollary to zipfs is false

but they are related for sure

PhiNotPi

I probably overstated when I said "totally unrelated." If you have categorical data (a list of words and counts of their occurrences, PIN counts, a list of cities and their populations), the relationship of word -> count follows Zipf's law, while the values of the counts follows Benford's law.

Q: Borders of overlapping circles

Given the coordinates of several points on a plane, and the radius of a circle surrounding each point, draw polygons representing the circles and the edges where the circles meet. Examples For example, given two points and two radius's, the output might look like this: Add another point and ...

The best data I can find so far is an ordering of all the common PINs. jemore.free.fr/wordpress/?p=73
