Whoa a first user has a non-trash answer

@DJMcMayhem how did you make this chart?

MD XF

Speaking of that question, should I protect it or no?

DJMcMayhem

@MDXF no

Q: When should challenges be protected?

Users with 3,500 rep (or 15,000 if when we get a site-design) can protect challenges. This makes it so that users who have not earned 10 rep on the site can not answer. As a user with this privilege, I have no idea when it would be appropriate to use. This is because the idea of "protecting ques...

Why not, there have been a lot of trashy answers

How can I allow legit output to STDERR (eg. fprintf(stderr, "Hello!"); but exclude interpreter / runtime warnings in this challenge?

MD XF

@programmer5000 Interpreter/compiler warnings are not allowed.

programmer5000

@MDXF is that objective enough?

MD XF

I assume you meant compiler warnings

ais523

@programmer5000 see here for my attempt at creating an error-dependent challenge

I'm still not sure if it's perfect

MD XF

21:57

'cause runtime warnings aren't really as much of a thing

ais523

plenty of languages have runtime warnings

most scripting languages, for example

MD XF

Oh wait yeah

ais523

bash, Perl, PHP…

MD XF

Wait no

those are interpreter warnings

IIRC

ais523

yes, but they still happen at runtime

also many Perl warnings come from Carp

which is a library whose purpose is to handle runtime warnings

rather than from the interpreter itself

programmer5000

21:59

So Interpreter/compiler/runtime errors/warnings are not allowed, but output to STDERR is allowed?

ais523

that's the sort of thing that I consider perfectly clear, but that people insist on maliciously misinterpreting

programmer5000

@ais523 If they do that, I will unleash my SE mod sockpuppets to mass-downvote and deletevote the answer until they have 1 rep or delete it.

ais523

how many sockpuppets do you need to downvote people to 1 rep? :-D

MD XF

@programmer5000 Sounds good

@ais523 About 8000

I have 50 :P

but I forgot the passwords to a lot of them

ais523

and where do they get the rep to afford downvotes?

MD XF

22:03

From posting good answers

For example, Jon Skeet is my sockpuppet

ais523

given the normal methods used to identify sockpuppets, I'd say that if that's the case, you're Jon Skeet's sockpuppet instead

MD XF

Nahh. Jon Skeet doesn't follow the normal rules

programmer5000

Thanks for the help on this!

MD XF

@programmer5000 Needs a better title

People will see that title and DV/VTC without even reading the question

programmer5000

@MDXF what do you suggest?

MD XF

22:07

@programmer5000 I'm rushing to a meeting rn so I can't think of anything, but not that :P

Alliteration, mostly. Also, hi everybody! PPCG seems to be an excellent spot

@MDXF this too

@MDXF oh, I mostly just help idiots

@programmer5000 Most of my SO rep is from "how do I print an integer in C"

Most of my answers are 0 or 1 vote

well not most of my so rep

but the highest voted answer

programmer5000

Woah

MD XF

@programmer5000 me too

programmer5000

My rep from SO today = my rep from PPCG today

MD XF

Oh wait no it's this

A: How does 'if((x) || (y=z))' work?

No. if ((x) || (y = z)) { in C-English is basically: if x is nonzero, evaluate the following code. if x is zero, set y to z. if y is nonzero, evaluate the following code. otherwise, break out of the loop. If x is zero or y is zero, it breaks out of the loop.

At least it's not as awful as the covfefe question

Oh gee thanks to whoever just downvoted that :P

@MDXF I downvoted it

but a few hours ago

MD XF

Why ಠ_ಠ @programmer5000

and actually no it was one minute ago

Potato44

Does anyone here have a recommendation on a trefunge interpreter?

quartata

@Riker I mean, there isn't any particular reason to assume the system's going to be Linux

MD XF

22:23

@Potato44 yeah

quartata

Assuming it's System V is actually fairly safe, more things will be compliant with that

Phoenix

There are still things running on Cobol, so...

@Potato44 tio.run/#befunge is I think what you're looking for.

Potato44

@Phoenix does it actually support trefunge?

Phoenix

I thought you misspelled befunge because I didn't think trefunge was a thing

It does not appear to be on esolangs.org

trichoplax

If it's not on esolangs.org that makes it a production language

Potato44

22:26

@Phoenix its an extensiom of befunge98 that uses form feeds to seperate to the 3rd dimension

Phoenix

@trichoplax Clearly it is not

Potato44

It is referenced on esolangs from the befunge98 page

trichoplax

OK, that settles it then

@Phoenix Clearly :P

programmer5000

Covfefe has 333 score now!

Potato44

Okay, found a trefunge interpreter that at least looks like it might work called stinkhorn

IMO Sp3000 is the most impressive user

He's not completely devoted to this site (like I am) but he has a ton of rep

I mean, he generally gets around 50 rep a day

@MDXF That is incorrect, the most impressive user is Dennis

MD XF

@Phoenix Okay true

this makes me feel much more proud of my 2-d lang

Riker

23:11

@quartata what part of the nethack src controls feature placement, i.e. altars or fountains?

quartata

mklev.c

let me find you the specific line for altars

the function is mkaltar

so just search for that and you'll find something like this:

        if (!rn2(60))
            mkaltar(croom);

change the value in rn2 (random number generator) to adjust the frequency

Riker

thanks

quartata

take a look at the surrounding code to figure out what's going on

fountains are a couple lines up

Doorknob

Ooh, see if you can find the part where it checks to see if I'm the player and drastically decreases altar frequencies if so

5

quartata

hahahaha

Well I mean 1/60 is rare

-ish

Riker

23:19

@quartata yep, found that

quartata

what are you changing?

only time I really had to touch this part was to increase swamp generation

Riker

@quartata pls no

I hate swamps

quartata

They're kind of necessary

otherwise you die of thirst in my fork

Riker

@quartata nothing useful, just messing around with increasing item drops/features

i.e. every room has 1 feature + 1 item guaranteed

quartata

ok so looking at the code

I actually made 1/4 rooms swamps

now

that might be a little too much I think

but amusingly enough in-game it doesn't seem that common

maybe my own fork is giving me bad luck

Oh:

trichoplax

23:27

Is that a surprised face being stabbed with a bad luck fork?

Riker

@trichoplax that... is an interesting interpretation

@quartata yes?

quartata

#ifdef QNETHACK
char* name = getlogin();

if (!strcasecmp(name, "quartata") || !strcasecmp(name, "doorknob")) {
  # haha no swamps for you nerd
} else {
  if (!rn2(4))
    mkroom(SWAMP);
}
#endif

Riker

hahahaha

Doorknob

... interestingly, that will never generate swamps, because strcmp and friends return 0 only on equality.

quartata

gee I was in a rush sue me

it was a lame joke anyways

Riker

23:29

@Doorknob lol

@quartata where's qnethack stored? mind if I peek at the code?

quartata

it's on my hard drive never to see the light of day

and I just noticed I used # for comments

MD XF

@quartata I noticed that and was very confused

Riker

> MON("giant ant", S_ANT, //4
LVL(2, 18, 3, 0, 10), (G_GENO|G_SGROUP|3),

@quartata which number is frequency?

i.e. generation frequency

oh, I'm an idiot, I can check the wiki
