@Riker For future use: function upload_stack(url) { $.post("/upload/image", {"upload-url": url}).done(result=>console.log(result.match(/http[^']+/)[0])); } 1:30 AM Is C's FILE* stdout not in libc?: Undefined symbols for architecture x86_64: "_stdout", referenced from: _main in .vsl-temp2c713c08.o 0 (The text asks how many boxes there are in the picture) Now you are required to generate such a problem and its answer.

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' 0 The TI series of calculators. I've put a lot of hours in writing TI-BASIC programs.

(yes?) @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"?

@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

Yeah

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

huh

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.

: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

I have a link in my profile, advertising a Stack Exchange question of mine (which I believe is acceptable use of the profile page). The link works fine on my individual profile pages. For example, my CG profile and my PPCG profile. However, on my network profile the links do not show. The link i...

Thought so

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...

@Mr.Xcoder Yeah, because it's sponsored :P

yeah ik

y'all got the email right

No email though

Lol Riker's the #1 on QC

ofc
I was the first by like 5 minutes
(there's a deleted #2 that's not visible)

I get the feeling Riker might become a another mod :P

vote riker for mod

doubtful

tbh I have very little experience in this area
@Mr.Xcoder that guy posted #2
@Mr.Xcoder no repro
you zoomed out/in?

Nope

Annoyingly, I want to ask a question, but I don't have anything to ask, and joined the proposal mainly because I find it interesting, but not something I'd ask about :/

> If you've been cleared for graduation but don't yet have a design, someone from the community team will be posting on your meta site in April to get some input so we can get your site themed based on your answers. We will start enabling the new design across the network in May.

@Christopher No, I rolled it back. The title is supposed to be like that, and you misspelt Formatter

I promise not to do anything but invite you

(Pretty sure I stuck it in tnb at one point or the other)

6:08 PM
@Pavel you really think I will search for it :P

But yeah, one sec

Q: Can we reject the new design?
And if so, should we?

I joined QC without being signing up for the private beta

O_O

@cairdcoinheringaahing I don't know about can, but I'd guess the answer is no. Follow up question, why would we?

6:11 PM
@cairdcoinheringaahing What design?

31

Ch-ch-ch-changes are coming. As you've hopefully read in our various posts on Teams, we are in the midst of some major work. We're introducing a new product, Teams (née channels), and doing the requisite research and design thinking to get it right. In addition, early on we realized that we have ...

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

@Christopher Done

@Pavel Invited :)

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

6:12 PM
Thanks!

@Mr.Xcoder Close enough :P

@DJMcMayhem Ew, left nav.

Imagine how much of a let down it would be, after all those years of hoping, that we end up with a design like this. I, for one, would just not use it, and stick with the Gradscript

We better be getting that Cadillac treatment

Dreams...

6:16 PM
@Mr.Xcoder people think that asking if quantum pairs can be used to QC is off tompic?

In other words, the only customisation will be colours. Not even fonts!

@Christopher I do too (though I didn't DV).

@Pavel bringing in the Official MS Knowledge™ (lol I see yer comment)

ಠ_ಠ I'm going through the old Add++ interpreters, and am thinking to myself Did I really think that recursion was the best way to loop?

Recursion is the best way to loop.

@cairdcoinheringaahing Recursion is evil.

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)

Can we at least select our fonts? I think the fonts give much of the feeling to a site, and may even affect usability.

Pro Tempore mods are announced after a while.

@Pavel until public beta

@Christopher Been there, done that.

@Pavel The CMs moderate until ProTem mods are annouced

@J.Sallé throwing myself under the bus for a meme is worth

Is everyone essentially considered an infinite-rep user permisions-wise until then

@Pavel nice meta

@J.Sallé hahah

@Pavel little before private beta ends, we get mods

Ah, ok

6:40 PM
@Pavel no, much lower thresholds tho (350 is all review queues iric)

@Riker Ah. I just cast a close vote with 101 rep and was wondering about that.

holy heck I just posted a very brief "Yes" to @Pavel's question and it got 2 updoots in 10s

One of them was me because I totally agree

I want to ask questions about Q#. I'm afraid they'll get lost on SO, since very few people know Q#, but I don't want to post to QC and get it closed and told to post on SO.

@Mr.Xcoder THB?

The h bar. The physics chatroom
(comes from $\hbar$, for those of us who have MathJax)

I'm pretty sure that that's not the case
I'm pretty sure that "h bar" has been around longer than tex.

Yeah of course, I was talking about what $\hbar$ represents, not the symbol itself.

His English is even worse than mine though (slightly) :P

7:36 PM

@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.

7:45 PM

@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
