The Nineteenth Byte

Wheat Wizard

3:01 AM

Does anyone program in common lisp a lot? I just got into CL from this answer and I'm having a lot of fun.

user2284570

@ATaco : why not ?

Pavel

@WheatWizard I think @DLosc and @Qwerp-Derp do

Riker

@user2284570 I use *nix and android soooo

and I have a vague idea, but it's best to be specific

user2284570

@Riker : soo you don’t even now it is the format used by all main executables on Linux ?

Pavel

Is *nix unix and linux or are there other things it can stand for.

@Riker Don't you use a Mac?

user2284570

3:07 AM

@Riker : it’s also the same for android since lollipop because of the ahead of time compilation change.

Pavel

Just because Android uses Elf files does not mean you look inside them.

I generally don't go through my phone's binaries.

user2284570

@Pavel : he just asked what it is. And don’t forget they are valid contests on this site with the elf format.

Pavel

You know what, I still think it's incredibly boring, but I can't really say it's unclear, so sure. Reopen vote.

ATaco

Regardless how valid the challenge is, as we've stated a few times now, "Write in this format" isn't a very good challenge.

Pavel

It's not a good challenge, but it doesn't violate any rules or standards.

user2284570

3:13 AM

@Pavel : correct there’s the vote system for that, not the close vote one.

Conor O'Brien

@Pavel I get a incompatible types: Object cannot be converted to Command (command being the class of the variable I tried to perform an assignment)

Pavel

@ConorO'Brien Is that a compiler error or exception

But I think what it wants you to do is make an explicit cast.

Conor O'Brien

compiler

user2284570

@Pavel : thanks, but I maintain it’s harder than it looks.

Pavel

@user2284570 Hard!=Interesting

Centering things vertically in CSS is also hard.

user2284570

3:15 AM

@Pavel : ok.

Conor O'Brien

@Pavel I added an explicit cast, but got unreported exception InstantiationException; must be caught or declared to be thrown

Pavel

@ConorO'Brien That is correct, there are like three exceptions you have to declare or catch.

Riker

@Pavel unix

@user2284570 I didn't mean "i have no clue halp me plz", I meant "you should specify that in the challenge"

I used to dual boot mint fwiw

and I don't know the specifics, but I know what it is, but obviously some people dont

Pavel

Do you have a Windows license?

Riker

me? no

well, yes, but it's not mine, only my dad uses a windows

also, who voted to reopen this?

Q: Shortest ELF for "Hello world\n"?

Is it possible to write (pack) a shorter than 145 bytes version of a program with "Hello world" (plus new line) output if the length of the program is measured as a number of bytes in program's ELF (x86) representation? Reduction technique in mind is described here: http://timelessname.com/elfb...

it's a clear dupe

3:22 AM

@betseg okay, I fixed bug, you can delete repo now

Conor O'Brien

what kind of bug did you--nevermind, I don't wanna know

user2284570

@Riker : I just thought it was as obvious as knowing what is a jpeg file if you have camera.

ATaco

I know how a JPEG File looks under the hood, but that's just because I wanted to export a JPEG using lua.

Pavel

@ATaco There's not a library for that?

ATaco

Probably, but I code with the "libraries are for chumps" motto.

Nathan Merrill

3:28 AM

...lets see how long that lasts :)

Pavel

> Don't reinvent the wheel

ATaco

It's not a very good motto, but I've learnt a lot

Nathan Merrill

oh, for learning purposes, its great.

but if you want to make anything permanent, libraries can surely write it better than you can

ATaco

Generally if I'm doing anything I plan to show others, I use libraries

Helka Homba

@user2284570 People are more intimate with their camera than their elf

@ConorO'Brien it wasn't too bad, just had forgot to update the username field (detailing which user's repos to list)

Conor O'Brien

@Downgoat ohh ok

Helka Homba

MCMC: Given N what is the total area covered by the circles (x, y, r) = (i, i, i) for i from 1 to N.

Pavel

@HelkaHomba MCMC?

Helka Homba

Math-CMC

e.g. if N = 3, what's the area covered in the plane by disks (1, 1, 1), (2, 2, 2), (3, 3, 3)

DJMcMayhem

That will be a lot harder than it seems

Helka Homba

3:43 AM

Yeah, not really so mini

CMC: Solve for N = 1 :p

Wheat Wizard

@HelkaHomba Do you know the solution?

Helka Homba

@WheatWizard no

Wheat Wizard

Ok so its extra fun

DJMcMayhem

@HelkaHomba I'm not great at math, but I'm pretty sure it's seven.

Wheat Wizard

It should tend towards (3π/2+1)(r*r)

Helka Homba

3:50 AM

@WheatWizard wouldn't it be 3/4 pi?

Wheat Wizard

No? I'm not sure why you say that.

perhaps I am misunderstanding the question

Oh yes I see

Helka Homba

r^2 for the bottom left "square" then 0.75 pi*r^2 for the other 3 quadrants of the circle

Wheat Wizard

you are correct

I must have mistyped. I thought you meant the entire thing would be 3/4 π.

Pavel

@HelkaHomba (s=0;For[i=1,i<=#,i++,s+=Area@Circle[{0,0},i]];s)&

Helka Homba

@WheatWizard Ah. No. I mean (3π/4+1)(r*r)

Wheat Wizard

3:53 AM

@Pavel That doesn't work. The circles intersect

@HelkaHomba Yes that is what I originally meant

Helka Homba

Pavel

OH I GET IT NOW

Helka Homba

@Pavel N = 3 looks like that ^^

If you could find the area left out along one axis it might be easy enough

Conor O'Brien

is there a closed form for the area of sector from a given segment?

Wheat Wizard

6 is the first circle to not intersect the first.

Pavel

3:56 AM

I'm trying to find a way to merge geometric objects in mathematica

Conor O'Brien

Wheat Wizard

@ConorO'Brien xarg.org/2016/07/calculate-the-intersection-area-of-two-circles

Its the area of the slice minus the area of the triangle created by the slice

Pavel

WHY IS THE SOURCE CODE NOT PROVIDED

user2284570

@HelkaHomba :)

Concerning posting, how to explain to stack exchange and Google recaptcha that I’m not a robot ?

Helka Homba

The area covered would be (3*pi/4 + 1)*r^2 + pi/4 - 1 - 2*(area of pink stuff) but finding the area of the pink is tricky.

Wheat Wizard

4:02 AM

@ConorO'Brien In short $A=(\theta/2-\cos(\theta/2)\sin(\theta/2))r^2$

(read as LaTeX)

Helka Homba

Pavel

4:09 AM

WHYYYYYYYYYY

Helka Homba

@Pavel Keep calm and ask Martin.

Pavel

Oh right, Marting isn't just a regex guru

@MartinEnder I need help, how do I overlap two geometric regions in Mathematica, into a format I can pass to Area?

I've been a bit (a lot) stuck on this.

Helka Homba

Maybe reference.wolfram.com/language/ref/RegionUnion.html ?

Pavel

*FLIPS TABLE*

WHY IS EVERYONE ELSE'S GOOGLE BETTER THAN MINE

Conor O'Brien

@HelkaHomba certainly has a nice solution...

Helka Homba

4:12 AM

@Pavel I'd cool it with the caps...

Pavel

I'm sorry

(s=0;For[i=1,i<=#,i++,s=RegionUnion[s,Circle[{i,i},i]]];Area@s)&

Helka Homba

Does Geogebra do permalinks?

Pavel

That did not work.

Pavel

@MistahFiggins I tried Bing, and Google, and Yahoo

@HelkaHomba works now ^?

Helka Homba

4:16 AM

Uhh

Doorknob

You could just do Area@RegionUnion@Table[Disk[{n,n},n],{n,#}]

Helka Homba

@Pavel I mean, it should be right from what I understand of the code

MCMC 2: Can the area of the union of two circles with integer centers and radii ever be an integer?

Mistah Figgins

@HelkaHomba besides 0? :P

Helka Homba

@MistahFiggins How would that work? (assuming the radii are positive)

Their intersection could be 0, sure

Mistah Figgins

That's what I mean

Helka Homba

4:30 AM

But I asked for union

Mistah Figgins

oh, gotcha. Thought you meant intersection

Helka Homba

I'm guessing the answer is no since Pi is transcendental, but I'm not certain

Pavel

You could try FindInstance in mathematica

Is jaywalking really legal in the UK? :o

Mistah Figgins

I can understand it being illegal in cities, but on, say, rural streets, it doesn't make much sense to me

Pavel

@HelkaHomba I hear people actually drive sanely there, so maybe it makes sense?

Mistah Figgins

I jaywalk every day, but on a street where there is maybe a 45 second break in traffic

Riker

@HelkaHomba they don't have boston

when you see boston you understand why the us has so many weird traffic laws

DJMcMayhem

@Riker Aww, not 5/7?

Mistah Figgins

5:06 AM

@DJMcMayhem that would be 100%, not 62.5%

Helka Homba

I apparently know 0/5 about Komodo dragons ._. (new Google doodle)

@Riker Is it a matter of complex streets? Because they couldn't be worse than much older british city's

ATaco

I may literally know less about my operating system than we as a species know about the oceans, but at least I know about Komodo Dragons!

@CheckOutTomato remember when I borrowed your .vimrc? How do I toggle the sidebar that shows on my files.

DJMcMayhem

.vimrc rule #1: Don't allow any lines you don't understand.

IMO, copying an entire vimrc over is never a good idea

Pavel

I don't have enough Vim skill for me to notice anything wrong

And when I do get enough Vim skill, this will seem perfectly normal.

betseg

I have no dragon doodles ;_;

What day is it in where you live?

Helka Homba

@Pavel I'm not sure if I get what you mean. I meant that you should write it yourself as you come across settings/mappings you like

betseg

5:41 AM

It's monday here, but I didn't have the doodle yesterday either ;___;

Pavel

@DJMcMayhem But I have all these cool plugins now

DJMcMayhem

Then copy the ones you understand and like

Just out of curiosity, can I see the .vimrc in question? Is it online somewhere?

Pavel

@DJMcMayhem Yeah, somewhere on Wat's website.

5:49 AM

@HelkaHomba Twin peaks, I'm pretty sure

Actually no, I'm positive

Helka Homba

Ah. Yep. Thanks

Pavel

@DJMcMayhem So, anything wrong with it?

DJMcMayhem

np. It was purely a guess from the title, I haven't actually seen twin peaks (but I've heard many good things about it)

@Pavel Not anything in particular. Just that I think it's kinda silly to copy a bunch of settings you don't understand

betseg

@DJMcMayhem I do this with everything related to my computer. I search my problem, find a command that I didn't see before, dive into man pages, find another related program, go to its website, and eventually, wikipedia page of common misconceptions.

Pavel

Well, I've looked through there, it mostly seems to be things I like.

Maybe there's a setting I don't know about that I would want, but I wouldn't have it anyway.

DJMcMayhem

5:54 AM

Hey, can I ask a random question? If you had the choice of playing The Last of Us or Arkham Knight, which would you rather play?

(Assuming you haven't played either)

@Pavel Part of it is that setting each setting yourself is a great way to become more familiar with vim. I've learned a ton from making my .vimrc

(Which is 371 lines ATM)

Pavel

Only?

I expected it to be a monstrosity spanning megabytes.

DJMcMayhem

If you include the plugins, it probably is

betseg

The Last of Us, because a) a friend plays it and says he liked it and b) I don't know anything about the latter

Pavel

Can I look at it, for curiousity's sake?

DJMcMayhem

@Pavel Absolutely

Pavel

5:56 AM

@DJMcMayhem Does that include recieving hardware necessary to play said game?

DJMcMayhem

If you already had the hardware and the games.

Pavel

I'm going to have to with The Last of Us anyway, come to think of it.

DJMcMayhem

Hmm. I'm leaning slightly towards TLU too. It's just hard to decide because of how much I've enjoyed the other arkham games.

@Pavel ^

Pavel

woah

I just realized that the only text editors on my computer that I don't use are Emacs and ed.

betseg

Oh I am dumb

I created another .vimrc for TTYs and aliased vim to use that .vimrc in TTYs without thinking I can check if I'm on a TTY.

You could make the flag go before the filename and ask Dennis to add interpreter flag support. Then you could allow RProgN2 to have proper ARGV support.

@ATaco tio.run/nexus/bash#@5@cWKJgY6Pg6u/…

Pavel

And then you could also have -d instead of --d

ATaco

I could, but as flags aren't an advantage in golfing, I'm neglecting them a little. Also, the describe flag isn't designed to be an auto-explain generator, just say what all the functions do

@MatthewRoh Re: my comment on the question--you may have misunderstood--I'm asking if the word o is a potential input. According to a very literal reading of rule 5, the plural would be os, since there is no consonant before the o.

Matthew Roh

Edited

DLosc

Sorry--I don't see how that edit addresses my question?

Matthew Roh

7:49 AM

btw 'roof' has two plural state thus not being one of the input

DLosc

Will o be one of the inputs?

That's what I'm asking. Is it like "roof," a weird corner case that we don't have to handle?

Or if we do have to handle it, then should the output be os or oes?

Matthew Roh

@DLosc os

<consonant> + `o` => oes
<vowel or blank> + `o` => os

DLosc

O

(Because, FYI...)

Matthew Roh

If thats the case it would not be input

it violates #5

Meta (from the Greek preposition and prefix meta- (μετά-) meaning "after", or "beyond") is a prefix used in English to indicate a concept which is an abstraction behind another concept, used to complete or add to the latter. == Original Greek meaning == In Greek, the prefix meta- is generally less esoteric than in English; Greek meta- is equivalent to the Latin words post- or ad-.

Safirah

Is it possible to alter the Object superclass?

Anonymous

9:09 AM

@Safirah As far as I know, not directly. You could possibly do some reflection shenanigans to load your own custom version of the Object superclass, but that would probably break a lot of things.

Safirah

@Mego please elaborate a little more

Anonymous

@Safirah With Java's reflection utilities (specifically ClassLoader), you can do a lot of stuff that seems cool but will probably get you into trouble. Specifically, you can dynamically load classes at runtime, and with a bit of trickery, you can even reload classes that have already been loaded (this SO question is a good starting point).

Anonymous

However, trying to reload the Object class this way will probably have a lot of unintended consequences, due to the fact that every other loaded class will be affected by the change.

Safirah

@Mego really? Well, let's see what I can do. Thank you for your help

Anonymous

Now that I think about it, simply reloading the Object class by itself probably won't do anything (except affect classes (re)loaded in the future). You'd need to reload every class currently loaded (reloading the Object class might automatically cause that reload cascade, but I don't think it would). Then you'd almost certainly run into trouble.

Anonymous

9:36 AM

Dynamically reloading one class is like playing with matches. Dynamically reloading the Object class is like playing with a flamethrower. And dynamically reloading every class is like playing with a flamethrower while soaked in gasoline and surrounded by a bunch of pyromaniacs with their own flamethrowers.

Then it's unsolvable

Then there's too much unknown in the system

This should be solvable quite easily if you treat the lawn as a simple uniform heap of organic mush that increases by itself over time (dg/dt=C) and that a cow can eat a constant amount over time (dg/dt = D*[cows])

no, the rate at which grass grows = 10/3 * how much each cow eats per day

Jan Dvorak

Which would mean you need 10/3 cows to keep the grass grazed

i think i found it on github

hmm looks like it's 0-indexed

although i suppose Kritixi could have been asking a question with 0-index in mind

the "zero-ith" element is in index zero, after all

@fergusq How do you get the nth char of a string? I am still trying to figure out how to convert a string to an array. print "string" | split("") works, but then I don't know how to get the nth element. Also a = "string" | split("") works, but a is given a string value instead of an array value

fergusq

@KritixiLithos The split function returns the fragments of the string in the stream (like multiple return values). Also the separator must be given as a named argument: split(sep=""). To make an array, put braces around the function call: [push("string") | split(sep="")].

The latest version also includes the / operator that returns an array: "string"/""
