@Geobits I think its due to the font. Chrome/Chromium/IE/FF all render the same for me.

so maybe linux has a different font which limits something

Q: Create an executable

Challenge Write a program, which creates a standalone executable file which takes a Fourier program (file extension .4) and compiles it to an executable. Source Your source code must contain only the following characters: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz@#%&-+()*"':;!?,_/.][>

ah, I was focusing on the 2nd part

@aditsu Well, to join forces, one of us has to incorporate bits of the other answer, and since you're currently ahead, it's only fair if it's you.

That's what I meant.

I'll think about it :p let me try to golf a bit more first

@CᴏɴᴏʀO'Bʀɪᴇɴ Does Simplex have wraparound capability?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@VoteToClose ish. I have a command that I've never used, it's called the mirror: |.

That little bugger reverses the command flow.

I'm removing it because it makes my life writing an interpreter hell.

@CᴏɴᴏʀO'Bʀɪᴇɴ See: Shakespeare

@CᴏɴᴏʀO'Bʀɪᴇɴ If you're writing in JavaScript, you can practically steal my method for this. :D

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@VoteToClose You wrote your interpreter in javascript too? :D :D :D :D

7:24 PM

No, Java - but they're mildly readable between. I just used arrays to define the position of things.

mildly

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Right XD

I'm mainly talking about the interaction of bracketed expressions.

Oh! So, like, loops with instruction pointer directional-specific functions?

If you were using brackets, [ starts while when coming from the left, ends from the right, no?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Yeah, that's right

I know I could add some functionality to do it, but its not worth it for a single command.

That mirror mocks me every day I see it in my docs. |

It was a Lennipede

No

"Lennipede" is intended to be a portmanteau of "Lenny" and "centipede."

@AlexA. btw, your gf watches one piece ?

@VoteToClose VTC as unclear. Define "Alex's method"

@VoteToClose My method of Lennipede generation was to find it on a really odd website dedicated to the Lenny face and copy/paste it here.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@VoteToClose It wouldn't work the way I've written it.

I got a 503 from disapprovallook.com: Exceeded the maximum global requests per minute for crawlers or humans. What is my life.

@CᴏɴᴏʀO'Bʀɪᴇɴ Before you do that, try to guess if I approve of that statement.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

<Geobits Bot> I disapprove.

8:06 PM

soo, "I approve this statement" vs "I approve of this statement" - which is correct?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I wrote the bot in English.

Ok, sounds like this bot may have at least partial success.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Optimizer Both!

Yes.

either i'm getting better at brainfuck or i'm getting better at finding challenges that won't be hard in brainfuck

Without the 'of' it's more of a personal approval of the sentiment expressed. With 'of', it can simply be approving it without agreement. Or at least that's the way I read it.

> won't be hard in brainfuck

Isn't everything hard in Brainfuck?

undergroundmonorail

there's a challenge on this site that ,[>.+<-] would be a valid answer to

my answer is a lot longer because i chose to work with decimal digits instead of inputting and outputting byte values

undergroundmonorail

8:10 PM

literally any file is a valid brainfuck program

Yes, but ; is a noop

So it will output a null byte

that centipede thing reminds me of an interview with Sarah Silverman :p

8:11 PM

fun fact about the ,[>.+<-] program: it uses every instruction in the language exactly once

saw? no, that's a different movie

On a more relevant note, something should really be done about the logic tag. The tag excerpt (sp?) is literally a joke. And I'm not sure it provides any meaningful context to a challenge as is. Might be better as boolean-logic or similar. Thoughts?

@AlexA. Vulcans?

Or Yoda, perhaps?

thinking about giving a link... better not ^_^

at least 3 users here are aware of what goes on in 4chan

it's not about 4chan

@aditsu its not, but the starrers got the reference

I suppose it's fairly popular there, but I visit very rarely

4chan is not popular anywhere in general

undergroundmonorail

popular among 4chan users

maybe among terrorists .. (from recent news)

8:16 PM

I was talking about that concept being popular on 4chan

oh! I assume every such concept is popular on some sub 4chan

9:09 PM

Half rhyme or slant rhyme, sometimes called near-rhyme or lazy rhyme, is a type of rhyme formed by words with similar but not identical sounds. In most instances, either the vowel segments are different while the consonants are identical, or vice versa. This type of rhyme is also called approximate rhyme, inexact rhyme, imperfect rhyme (in contrast to perfect rhyme), off rhyme, analyzed rhyme, or suspended rhyme. == Use in hip hop/rapEdit == Half rhyme is often used, along with assonance, in rap music. This can be used to avoid rhyming clichés (e.g. rhyming "knowledge" with "college") or obvious...

@Rainbolt Um, really?? I have astigmatism too, but I don't want to squeeze my eyeballs to test it. I know squinting improves short sight just by restricting the field of view (so the blurring is less). You can get surprisingly good distance vision if you're short sighted by looking through a pin hole in a piece of card

> I don't want to squeeze my eyeballs

3

why not

um.. does everybody have astigmatism? do I?

Huh ... in my head, I always pronounced it pɪθ, as in "pithy"

@aditsu I've always said πþ.

9:11 PM

Despite past experience, I don't want to assume everything Rainbolt says is good advice

4

I don't think restricting your field of view magically makes the view you can still see less blurry. I think that's in your head. What makes it less fuzzy is you actually changing the shape of your eyeball when you squint and apply pressure to your eyeball using your eyelids.

@VoteToClose that depends on how you pronounce those 2 symbols :p

@Rainbolt No restricting the field of view has a definite explainable effect. I'll see if I can find a picture

Quick fix for bad eyesight: turn on the camera on your phone and hold it up to your face

@Rainbolt In searching for a picture I found this:

Pinhole glasses

Pinhole glasses, also known as stenopeic glasses, are eyeglasses with a series of pinhole-sized perforations filling an opaque sheet of plastic in place of each lens. Similar to the workings of a pinhole camera, each perforation allows only a very narrow beam of light to enter the eye which reduces the size of the circle of confusion on the retina and increases depth of field. In eyes with refractive error, the result is claimed to be a sharper image. However, a second effect may appear at the common bridge between each two adjacent holes, whereby two different rays of light coming from the same...

@Rainbolt I can't find a useful picture now, but the explanation in words is that being short sighted means a point in the image you are looking at is focused to a small circle on the retina, instead of a point. The pinhole reduces the size of these circles, improving the clarity of the image. For me, it doesn't just make it feel better, it allows me to read things I couldn't without glasses otherwise.

9:23 PM

^ This

My right eye is very shortsighted; I can't read any of the words on this screen by squinting through it.

On the other hand, making a small hole by curling my finger allows me to read the text perfectly

@Justin The trouble is that we have two conflicting hypotheses - Rainbolt's being that the shape of the eyeball is changed by squinting.

Anonymous

@NewSandboxedPosts This is a perfect task for Python generators :)

@Justin Ah - that does seem more conclusive since the eyeball isn't being squashed

@trichoplax My point is that squinting doesn't allow me to see, but making a small hole does.

Yes

@Rainbolt maybe try this? ^

9:27 PM

myopia.org/pinholes.htm

(No idea how valid this is)

Umm that page suggests pinhole glasses as a substitute for prescription ones. I do not recommend obeying that suggestion.

Circle of confusion

In optics, a circle of confusion is an optical spot caused by a cone of light rays from a lens not coming to a perfect focus when imaging a point source. It is also known as disk of confusion, circle of indistinctness, blur circle, or blur spot. In photography, the circle of confusion (CoC) is used to determine the depth of field, the part of an image that is acceptably sharp. A standard value of CoC is often associated with each image format, but the most appropriate value depends on visual acuity, viewing conditions, and the amount of enlargement. Properly, this is the maximum permissible circle...
