Given that it's consistently around this time that I start having issues, I suspect the cause of the problem is related to Chrome not being able to get enough memory/CPU time due to some scheduled task or service eating too much

7:16 AM

@TonHospel the timings are quite interesting... this is for n = 22 and m=0..21 in seconds and the total time for 5 iterations. 0.11, 0.61, 0.75, 2.99, 11.05, 47.59, 193.13, 712.70, 3309.94, 1988.28, 304.72, 97.18, 99.31, 6.26, 0.72, 0.20, 0.09, 0.09, 0.06, 0.06, 0.05, 0.04

Hi. I have a question. I posted something on the Cop's thread, and someone cracked it, but with a trivial solution which I failed to avoid when I chose what characters to hide.

Can I repost and show one more character to eliminate that solution? I want to see if someone will figure out my initial solution, which is somewhat strange.

Mars Ultor

@mIllIbyte Post a new answer

mIllIbyte

OK, thank you

Sp3000

You can try, but I'd recommend trying to crack it yourself so that the same thing doesn't happen twice

mIllIbyte

Oh, I see. I will do that, thanks.

Sp3000

That's probably going to take too long, but just thinking about what other people might try, other sequences that might fit, etc...

Katenkyo

8:35 AM

Personnaly, I'd love to see unintended solution when someone cracks my cop post

Also, I think it would be better to just edit and say how you wanted it to be, rather than doing a new answer

Sp3000

Technically they did crack it though :/

mIllIbyte

@Katenkyo Yes but I spent a lot of time on it initially. I'd rather see someone else crack the initial thing.

Katenkyo

@mIllIbyte I know it can be harsh, but posting the same answer with only trivial modification isn't reallywhat we like to do on this site

mIllIbyte

Well, then I will post something new which uses the initial idea.

Rather than just showing one more character.

Since the idea is not really "posted" yet, because it wasn't cracked.

Is that ok?

Katenkyo

Yep, totally ok, and may result in a great post :)

hi all

naive question perhaps but how do you draw in centimetres exactly in common languages?

that is that when you print it it comes out at exactly the right size

Geobits

You need to know/set the printer's dpi, for one.

Lembik

interesting.. you can't just do it as a function of the A4 dimensions for example?

I don't know how postscript/pdf works exactly

but I had assumed they would have a concept of distance independent of dpi

Geobits

I don't know the internals of pdf either, but when you said "common languages", that wasn't what I thought you meant.

I'm sure there's a TeX-y way to do it, for example.

Katenkyo

@Geobits Hum, I think TeX also uses DPI

aditsu

you can use cm in html/css

Katenkyo

12:50 PM

@aditsu They aren't really 'common language' ^^

aditsu

they're quite common actually

have you heard of this thing called the web? :p

Katenkyo

Or at least, not 'common programming language'

@aditsu That thing made by spiders under my desk?

aditsu

the question didn't mention programming, and neither did the followup

Geobits

In English (very common): Take a pencil and ruler. Line the pencil up with a starting point on the ruler, and use the markings on the ruler to achieve the desired length.

Katenkyo

I agree, that's what I'm assuming, because I don't see someone formatting a print in html...

aditsu

12:55 PM

I'm assuming it's something that you print though

html is a fine choice for that; odt or pdf might be better but harder to code

or svg

Katenkyo

1:31 PM

Hum, in code-golfs asking for output in the form of arrays/list/table etc

could I simply modify the input array by using its pointers ?

Geobits

I think by default modifying the input to give as output is allowed. Unless specified otherwise, of course.

Katenkyo

@Geobits I think I've read that to, but I don't really output anything, it felt kinda wrong

Geobits

Oh, I see. Yea, I meant modify and output (however output is done in the language).

Katenkyo

So I have to return it anyway?

Geobits

I'd say if it asks for output, it has to be done in one of the usual ways.

return would work.

That's how I've done it in the past at least.

Katenkyo

1:36 PM

Hum that's sad, for once one of the feature of lua was handy (tables are always passed by pointer, so...)

Geobits

Feel free to get a second opinion :)

Katenkyo

I'm going to dig on meta, it may already have been asked

Geobits

I imagine it might be in the default i/o listing post.
