Q: Generate a heap of boxes

l4m2 (The text asks how many boxes there are in the picture) Now you are required to generate such a problem and its answer. Input an integer n (optionally) random source of two values, in case you don't want to use the default random. Output can be a 3D array A[n][n][n], where A[i][j][k] =>...

Q: Are fixed input allowed if the bytes count?

l4m2E.g. requiring to call by f(4), and add 1 to the byte count Or maybe when inputting a choice, require input f`!#%` or f`&^%`, and add 6 to the byte count? Cuz we allow filename storage as long as its byte counted

 
does anyone know why this would throw:
const stdout: CFile = fdopen(1, `w+`)
also throws with `w` and a descriptor
exits with 'bus error'
 
2:15 AM
@NewMetaPosts someone answer this pls
@Downgoat wat
 
@ASCII-only I would if I could understand it
 
@DJMcMayhem they're basically asking of they can let the user input some variable they need
 
@ASCII-only How could that ever save bytes?
 
@DJMcMayhem IDK >_>
 
2:57 AM
@ASCII-only why 'wat'?
 
@Downgoat I don't understand how this could happen
@Downgoat I think you broke libc
 
No, you're opening STDIN....
Oh wait
My bad, misread the number :p
...are you sure the bus error happens when you open it?
 
3:44 AM
@DJMcMayhem It could certainly happen if you're golfing in brainfuck, for example. There was one submission I started (but never finished) where I appended ! and the alphabet to the program and then specified that the program be run in weave.rb, an interpreter that supports that.
That way I could initialize some memory without having to compute it.
 
@quartata yup
looks like I was opening during llvm.global_ctors
 
4:10 AM
What do you expect for this to print:
let a = 1
lazy let b = a
a += 1
print(b)
I am thinking 1 because integers are everything-by value (pass by value, etc.) so it only makes sense to be capture by value imo
 
@Downgoat I would say 1 as well
My intuition says that the expression b is assigned to isn't evaluated until it's needed, not that it's evaluated symbolically at the time it's needed.
 
@Mr.Xcoder you can boycott classes? What school do you go to :P here boycotting classes is called 'getting suspended'

kind of an odd question: does anyone here have a lifehack for getting correction fluid off of your fingers (especially on the nails :/)
 
@quartata usually scraping off with paper towel works
 
this stuff has been dry for too long
soap helped quite a bit to scrub it off but there's a spot on my fingernail that won't come off
I suppose acetone might work
 
4:43 AM
@quartata is it like the paint-style whiteout or like some other type
 
it's the stuff you put on with a brush yeah
which is why I figured acetone could get it off my nails
not for my skin obvs
ok I just filed it off lol
 
@EsolangingFruit This CMP should've been tagged PTIJ :)
 
5:37 AM
@Downgoat If you boycott more than 20 times without justifying them you get suspended.
So 1 doesn’t really matter anyway
 
oh
for us its 6
which includes sick days :/

Q: Third time the charm

workoverflowYour task, if you wish to accept it, is to write a program that outputs a positive integer (higher than 0). If the source code is duplicated the output must remain the same.

ughhh that maths assignment took longer than I expected
 
Having to pay 5 bytes for $(()) to do math hurts my soul

@user202729 Yes :P
 
3:28 PM
If I run chmod -R +x /proc/self/fd will it make all files created by <(...) executable?
 
@Pavel I doubt it
First, chmod runs as a separate process, so the changes will get lost the moment it's finished
But even then, <(...) creates a new descriptor
 
I wonder if there's any way to get <(echo echo Hello, World!) to work.
 
3:56 PM
@Pavel <(echo $(echo Hello, World!)) maybe? :P
 
@ASCII-only permission error
 
@Pavel What are you even trying to do
 
<() doesn't create executable files
 
@Pavel TIL: You are named after the first person you meet in Neverwinter NIghts
 
@ASCII-only Really hacky metaprogramming
 
3:59 PM
Using PHP right?
 
@Pavel What is the output file supposed to do
@Christopher ...
 
@Christopher That is extremely false
 
@Christopher "you"?
 
what about you?
 
@ASCII-only be executed. The <(...) is the entire command, not an argument to a command.
 
4:00 PM
@ASCII-only PHP=Hacky
or is he hacking ^_^
 
@Christopher that doesn't mean everything hacky is PHP
 
I could do bash <(...), but that's like 5 extra bytes.
 
@ASCII-only are you sure about that
 
Yes
 
4:02 PM
@Pavel do you know what <() is called
 
Nope
 
How is it different from just executing commands
 
@ASCII-only open heart?
 
@Pavel also that's not valid bash
 
What do you mean
Oh, zsh, not bash

But bash has <() too
 
You're getting permission denied right
 
Probably something to do with the virtual console's bash somehow having more priveleges?
@Pavel looks like you have no other choice here
 
4:06 PM
No it's because files aren't executable by default
You have to chmod +x
 
Right, but why does adding bash work :/
Also where does zsh even pipe to if you exclude the command
 
Because it's not executing the file
It's passing it as an argument to bash
 
@Pavel What file
 
@ASCII-only it's not a pipe, and it works in bash too
 
@Pavel Still an input stream though
 
4:09 PM
@ASCII-only <(echo Foo) is a file
 
O_o what
 
@Pavel new update to dot
 
You don't need to tell me that

4:14 PM
Is it just me or are links broken on Network Profiles? Compare e.g. my Judaism profile and PPCG profile with working links to the broken links on my Network Profile.
 
@Adám Have you tried clicking Update profile info?
 
@DJMcMayhem I didn't make a change recently.
 
OK, but it might be like turning it off and on again
 
@DJMcMayhem And it is like this for all profiles with links.
@DJMcMayhem You yourself have links in your profile. They are gone in your network profile.
 
:O You're right
 
4:22 PM
@DJMcMayhem Should I report it on mother meta?
 
If my comments are deleted, does it count against my "comment ban" or something?
(I guess no, unless I get a lot of spam comment flags)
 
@user202729 I don't think so. Comments get deleted all the time, especially on PPCG because of challenge clarification
@Adám I suspect it's intentional, but if you can't find a post about this, then go for it

4:39 PM
In probability theory, one says that an event happens almost surely (sometimes abbreviated as a.s.) if it happens with probability one. In other words, the set of possible exceptions may be non-empty, but it has probability zero. The concept is precisely the same as the concept of "almost everywhere" in measure theory. In probability experiments on a finite sample space, there is no difference between almost surely and surely. However, the distinction becomes important when the sample space is an infinite set, because an infinite set can have non-empty subsets of probability zero. Some examples...

We aren't the standard Q&A site, and if we get a design, I'd rather it was somewhat designed for the site (leaderboards/sort by byte count/etc.) rather than just a generic "Here are some colours so you feel included" design

@cairdcoinheringaahing We sure won't get leaderboards. And I think you meant byte count

6:23 PM
@WheatWizard no goto is only loop
 
tail call recursion is fine tho (That's what QUARK uses. Maybe. It's hard to classify how the interp does it internally, due to the messy shenanigans related to states, and execution depth)

7:36 PM
@Adám I'm guessing you got upvotes to get 200, then 2 downvotes
 
@cairdcoinheringaahing The why do I get to keep the badge?
 
Because you got 200 rep at some point in the day
 
I'm curious... What does it say on the bottom of meta.stackexchange.com/reputation ?
 
> days represented 29
rep cap was reached via rep from upvotes *only* on 0 days
earned at least 200 reputation on 0 days
earned 0 reputation from suggested edits
 
@Mr.Xcoder it was directed at Adam, since he got the Mortarboard, but apparently not 200 rep that day.
@Adám ^^
 
7:45 PM
@Adám the mortarboard description is misleading, it disregards negative reputation changes.
 
@cairdcoinheringaahing Apparently some people are against custom fonts. They have a right to that opinion, though, I'm curious what their reasoning would be.
 
unless you got "bonus" rep from accepted answers or bounties, it just means you hit the rep cap (but if you did then you don't even need to hit the rep cap)
 
@MartinEnder You might know better, but I think Epic / Legendary don't act the same way, right?
 
I think they do, given that Epic is the 'parent' of Mortarboard (in that it's the silver version)
 
@Mr.Xcoder they do, I believe
 
7:50 PM
@Adám Maybe they were from the devs and they'd rather not implement that possibility :P
 
@Adám The mortarboard/epic/legendary counting is wildly inaccurate and super buggy. I once got a point towards epic having only received 170 reputation that day (no downvotes or deleted users or anything).
 
hm, did you put up a bounty that day?
 
No I didn't have any negative reputation changes
 
that's really odd
but yeah, it's confusing either way
 
I did receive a bounty
But my total (with the bounty) didn't hit 200
