I mentally merged those into "relationships are hard, that's why I wrote this algorithm..."

Someone

01:27

so I was asking on TGC about how the hecc to do this thing and michael homer went "bruh just use polymorphism"

and then I realized I knew literally nothing about c++ polymorphism

CMC Solve some NPC for n=10000 popularity-contest Notice that 3-SAT with first n^0.01 rules is an answer, so this is not pure code-golf

Seggan

@RydwolfPrograms even after reading this, i did the same thing

@RydwolfPrograms yeah thats why i dont do this stuff (as in i have feelings towards people but i prefer not acting upon them)

(for now at least)

l4m2

02:41

Round towards negative is ⌊⌋, is there symbol round towards 0?

Bubbler

@l4m2 modern SAT solvers are really fast. benchmarks from SAT competition include testcases with 10000+ variables and 10^6+ clauses

l4m2

@Bubbler Fast for average input, slow for constructed ones

Bubbler

well sure, there is adversary input for any solver

but the testcases are from real world scenarios and being fast on them is practically important

Rydwolf Programs

03:04

@l4m2 Wikipedia doesn't have anything

trunc/truncate is probably the best you'll get

l4m2

If used a lot, defining as ├.┤ seems reasonable

Rydwolf Programs

I've seen ⌊⌉ used for rounding to the nearest integer, if it's in a context where you're not ever going to use that it seems like it would be sensible to use it or its inverse for truncation

(I say its inverse since it would sort of communicate "lower numbers [to the left] get rounded up while higher numbers [to the right] get rounded down")

Seggan

@lyxal apparently "australia doesnt exist" is a real, non-joke conspiracy theory. can you confirm that for me?

Rydwolf Programs

03:23

It is

You probably wouldn't encounter it in Australia tho I would guess lol

Seggan

I mean can you confirm Australia does or does not exist for me lol

Rydwolf Programs

ohhh lol

lyxal

@Seggan Australia exists

Duh

Why would we have a whole fake country to distract people from all the other secret experiments the government does?

Why would we spend billions convincing people of a lie to protect investors interests?

Why would we go and smuggle a country into every atlas, globe and other world map and burn all the old maps (except for one or two that you definitely can't find on the second floor of the non-existent Australia doesn't exist hq)

That would be preposterous

Silly, even.

Having said that, I do notice they're getting a bit greedy on the acting contract

Might have to do some blackmailing

See if I can't get a pay raise

ATaco

Ooooh, I should write a language that transpiles to C
Because all I want is C with fake classes. They don't need to be real, just functions being called from the provided type information

The hard part is it also needs to support C so I can parse C headers...

But really it should just be a C extension

Neil

... that's how C++ started...

ATaco

C++ is evil

I need no mess of Smart pointers nor inflated standard libary

modern C++ is so far removed from C it's sad

Bubbler

I guess you can do this

ATaco

06:24

There are dozens of hacks one can do
But a lil' ol' writing a language never hurt anyone

Adám

06:42

@ATaco Lil

Neil

06:52

looks like something called Comeau was the last C++ compiler that actually bothered transpiling to C

l4m2

I use C with class with template with stl, what in C++ not covered?

Q: How can I reduce the characters in the following python code?

The following code is 47 characters. print(("Ekki v","V")["COV"in input()]+"eikur!") How can it be reduced to 46 or less? I have even been brainstorming bitwise tricks but can not think of any way to do this. I am starting to think it is not possible to reduce this any further.

zoomlogo

@Bubbler is there a way to implicitly pass the this parameter

of the sum function

emanresu A

07:53

Love to see an answer golfed 10 years after being posted

Bubbler

@zoomlogo not in vanilla C, but I meant a transpiler can insert that for you

mousetail

@NewPosts The comments feel suspiciously AI generated, though that wouldn't really make sense

mousetail

They unfriended me soon after this

#define while(cond) for(;cond;)

Someone

11:56

idk if this is impostor syndrome or what, but I don't think real programmers freeze like deer in headlights when someone tells them to use polymorphism

is “Learning J” down? the table of contents works but on the individual chapters i’m getting “Safari can’t open this page because it couldn’t connect to the server.”

RubenVerg

13:07

@Someone who cares about being a "real programmer" anyways? as long as you get to code what you want to code it doesn't matter if you're considered real or not (:

3

and of course you can't expect to know how to do everything

i guess a "real programmer" is one who is open to learning new stuff

Ginger

13:26

real programmers are able to be represented by a possibly infinite decimal expansion

lyxal

13:46

can represent me, for example

mousetail

13:57

@Ginger So programmers are uncountably infinite? (And somehow still not been able to solve P vs NP)

Ginger

apparently :p

Rydwolf Programs

@Someone Tbf I didn't know what that word meant until like a year ago and I've been doing this like 8 years

You're a "real programmer" as soon as you program, and if you're in TNB, you're probably a better programmer than a lot of people

RubenVerg

@Ginger oooh do i get to pick mine?

mousetail

Polymorphism is pretty abstract and a bit hard to apply in real situations. But generally it's advised to use polymorphism over conditionals whenever possible, even in functional programing

Ginger

@RubenVerg sure, you've got plenty of options

Rydwolf Programs

14:03

@mousetail Not necessarily, the set of real programmers can be a finite or countably infinite subset of the reals (which makes sense, otherwise we'd get real housewives and Real Donald Trump in that set)

mousetail

I would watch a series with a uncountably infinite number of characters. (@netflix please hire me)

Rydwolf Programs

Welcome back to season sqrt(3)

Ginger

the Real Housewives of Hilbert Hotel

Rydwolf Programs

Only a subset of the real programmers out there are rational

Ginger

hang on I just remembered a message from, like, a year ago that I could make a joke about

RubenVerg

14:07

@Ginger i would like to be the dottie number please (the solution to $\cos(x) = x$)

Ginger

something something scala programmers

mousetail

@RydwolfPrograms An infinitesimal small proportion of them

Ginger

@RydwolfPrograms he was only a year and a half early :p

I think that took longer to send than normal

Rydwolf Programs

Maybe it had to do a DB lookup for a late reply and something slowed that down

Ginger

cache miss?

Rydwolf Programs

14:10

Oh yeah maybe they use an in-RAM memory store for most of recent history? But late replies are still usually faster

And I don't think chat's that smart :p

Ginger

might be a default config thing

and it wasn't super slow, maybe half a second longer than normal

Rydwolf Programs

Yeah, who knows. Chat's probably like one of those mazes on the backend anyway, where the more you think you know about how it works the more it shifts and changes when you're not looking

New bugs appear and disappear out of the chaos, in equal and opposite pairs. They usually get sucked back in relatively quickly, past the event horizon, but sometimes one will escape while the other falls in

Ginger

~~The Nineteenth House Of Leaves~~

it's really interesting to me that the new image uploader doesn't touch text chunks... cursed out-of-band signalling, anyone? :p

Rydwolf Programs

That's probably better to do via ordinary steganographic techniques tho tbh

Ginger

wait, hang on

Rydwolf Programs

14:15

Did I ever tell y'all about my totally awesome LLM-based steganography technique?

Ginger

no way, APNG works!

Rydwolf Programs

NB: Steganography is not to be confused with Stegganography, the study of hiveminds

@Ginger Whoa neat

Ginger

ok wait hang on

aw, it doesn't work for profile pictures :(

the resize parameter breaks it

Rydwolf Programs

sad

Seggan

@RydwolfPrograms I never did fully realize just how bad most programmers are

Ginger

14:20

CM(ega)C: make a PNG quine, i.e. a PNG image which displays a hexadecimal representation of itself

3

Rydwolf Programs

I think that's deserving of CMegaC :p

Ginger

unfortunately, gifs don't animate in pfps either

Rydwolf Programs

14:43

Lmao I hit the top of the APStudents subreddit by complaining about College Board's janky printing

Ginger

@Ginger a good place to start for this would be with a zlib quine for the image data

you'll probably have to brute-force the CRC32, though :p

Rydwolf Programs

Whoa we have five pins rn

Ginger

or come up with some other way to manipulate it

it'll actually have to be a meta-quine lmao

Rydwolf Programs

This is like when you've just gotten out of a prolonged fight with a skeleton

Someone

@RydwolfPrograms nah, I'm just here because it's vaguely code-related

you don't need a lot of rep to be in a chatroom

and I've answered—what, two challenges? and made absolute failures of challenges of my own?

noodle man

15:18

@Someone nothing stopping you from doing more :)

Someone

ah yes, pollute the question space

also, I keep getting sniped by people—most of the time when I find a challenge at my level, all the langs I'm good at were already consumed

Rydwolf Programs

15:47

240% on an assignment lol

My teacher just puts all the extra credit on the same assignment so it's piled up so much xD

noodle man

@Someone yeah i don’t really have advice for that..i just use more obscure languages so i have less chance of collision

you can always post your solution even if somebody else has a shorter one in the same language. you can compre yours to theirs and learn from what you missed

Rydwolf Programs

Whoa I only need a 73 in environmental science this 6-week grading period to average out to a 90 for the semester lol

Someone

16:56

@RydwolfPrograms L O L

Seggan

19:13

@Ginger impossible, probably due to needing more data to display an area than what the area displays

Unrelated String

png supports deflate compression

Ginger

19:37

yup, in fact it's required

I'll believe it's impossible when you show me a proof :p

Q: Golfing the complexity with subtraction

The Mahler-Popken complexity, \$C(N)\$, of a positive integer, \$N\$, is the smallest number of ones (\$1\$) that can be used to form \$N\$ in a mathematical expression using only the integer* \$1\$ along with multiplication, addition, and parentheses. Here are some expressions for \$N=6\$, \$N=1...
