where are websockets?

shadow scroll Dec 3, 2022, 7:55 PM

#

^

#

why are you math in asm/

hasty condor Dec 3, 2022, 7:55 PM

#

its asm math or something lmao

high sequoia Dec 3, 2022, 7:55 PM

#

looks like it's using discord++

hasty condor Dec 3, 2022, 7:56 PM

#

oh

high sequoia Dec 3, 2022, 7:57 PM

#

ah yet another library with a confusingly similar name

hasty condor Dec 3, 2022, 7:57 PM

#

great name guys

shadow scroll Dec 3, 2022, 7:58 PM

#

:/ not always

#

Your compiler does many optimizations

high sequoia Dec 3, 2022, 7:59 PM

#

not necessarily

hasty condor Dec 3, 2022, 7:59 PM

#

i would say " hand written assembly is rarely better than C/C++ code "

high sequoia Dec 3, 2022, 8:01 PM

#

casually does not tell the compiler to optimize

hasty condor Dec 3, 2022, 8:01 PM

https://godbolt.org/z/9c3GeTfc1

Compiler Explorer - C++ (x86-64 clang 15.0.0)

uint64_t factorial(uint64_t n) {
uint64_t res = 1L;
for(uint64_t i = 1L; i <= n; i++) {
res *= i;
}
return res;
}

shadow scroll Dec 3, 2022, 8:01 PM

#

I thought the rust take was bad but this is worse

hasty condor Dec 3, 2022, 8:02 PM

#

but clang made code thats a lot faster

shadow scroll Dec 3, 2022, 8:02 PM

#

and some of the code assumes longer life

hasty condor Dec 3, 2022, 8:02 PM

#

does it matter

shadow scroll Dec 3, 2022, 8:03 PM

#

^ also better to interpret

hasty condor Dec 3, 2022, 8:03 PM

#

no

shadow scroll Dec 3, 2022, 8:03 PM

#

?

sharp iris Dec 3, 2022, 9:07 PM

#

doesn't mean shit, 3 instructions can run faster than a single one

average compiler when SSE exists

faint marten Dec 4, 2022, 9:24 AM

#

wrong

#

wrong

hasty condor Dec 4, 2022, 9:25 AM

#

not on -O3

faint marten Dec 4, 2022, 9:26 AM

#

and in addition, have you measured a significant enough slowdown to warrant you writing your own factorial and fibonacci function?

#

and did it improve after you switched to assembly?

#

ok, so it seems you only ever use factorial as a command used by the user to calculate the factorial

#

and fibonacci is never used

#

so how the hell would this benefit anything?

#

even on -O0, it would make zero difference

desert niche Dec 4, 2022, 9:41 AM

#

the link i posted is the reason why everyone should use x86-64-v3

faint marten Dec 4, 2022, 9:45 AM

#

what if my CPU doesn't support that?

desert niche Dec 4, 2022, 9:46 AM

#

it does

faint marten Dec 4, 2022, 9:46 AM

#

my laptop's CPU doesn't

#

but looking at this code, holy hell

deep oriole Dec 4, 2022, 9:50 AM

#

how old is your laptop

faint marten Dec 4, 2022, 9:51 AM

#

10 years

#

model is from 2007

#

has a 32-bit Intel Atom CPU

hasty condor Dec 4, 2022, 9:53 AM

#

my laptops cpu doesnt support it either

#

and neither does my phones cpu

deep oriole Dec 4, 2022, 10:04 AM

#

well my phone doesnt support it either

desert niche Dec 4, 2022, 10:15 AM

#

ur all poor

faint marten Dec 4, 2022, 10:21 AM

#

Mint billionaire confirmed?

desert niche Dec 4, 2022, 10:21 AM

#

it's called investing in intel

#

💅

faint marten Dec 4, 2022, 10:25 AM

#

you mean shorting Intel?

desert niche Dec 4, 2022, 10:30 AM

#

xd original jok

high sequoia Dec 4, 2022, 2:57 PM

#

sounds like a bad impl of fibonacci then

faint marten Dec 4, 2022, 2:59 PM

#

or a bad impl for the command

faint marten Dec 4, 2022, 7:02 PM

#

that still sounds like bad implementation

hasty condor Dec 4, 2022, 7:09 PM

#

*very bad

#

me: my bot crashes because my aes impl isnt quite working

#

mcauc78: bot crashes with big numbers

hasty condor Dec 4, 2022, 7:10 PM

#

hasty condor me: my bot crashes because my aes impl isnt quite working

(yet)

faint marten Dec 4, 2022, 7:12 PM

#

well, what if you pass it rdi 0, 1, or 2?

#

but to come back to the original point, there must be reason it crashes for large numbers

#

that reason may be outside of the fibonacci function

#

but that doesn't matter

#

which is wrong for zero

#

?

quartz ember Dec 4, 2022, 10:12 PM

#

English please

#

“well, let's make n < 2 equal to n” according to Google Translate

faint marten Dec 4, 2022, 10:15 PM

#

please don't randomly speak an language other than English in on-topic channels, in the middle of a conversation
not only does that disrupt the conversation, it is a violation of Rule 7

#

you say "I know"

#

but if you knew, you wouldn't have done it, right?

#

unless you are intentionally breaking the rules

so you want to get banned?

#

look, if you continue acting like this
i.e. seemingly not understanding/taking seriously the warning
you leave me no choice

#

are you going to do this again?

high sequoia Dec 4, 2022, 10:41 PM

#

desert niche the link i posted is the reason why everyone should use x86-64-v3

it's called gentoo with -march=native

quartz ember Dec 4, 2022, 10:49 PM

#

It won’t work

faint marten Dec 4, 2022, 10:50 PM

#

64-bit OSes only work on 64-bit CPUs

shadow scroll Dec 4, 2022, 10:59 PM

#

i smell a hammer

faint marten Dec 4, 2022, 10:59 PM

#

well, your smell might be correct

desert niche Dec 5, 2022, 6:57 AM

#

high sequoia it's called gentoo with -march=native

yes but no thanks

#

not because i am opposed to the compile times, but because portage sucks massive cock

quartz ember Dec 5, 2022, 6:58 AM

#

~~just get good~~

desert niche Dec 5, 2022, 7:00 AM

#

yes portage should get good indeed

quartz ember Dec 5, 2022, 7:00 AM

#

Writing your own package manager from scratch is obviously the better choice

desert niche Dec 5, 2022, 7:02 AM

#

id rather do that than use portage

quartz ember Dec 5, 2022, 7:03 AM

#

Lol

desert niche Dec 5, 2022, 7:06 AM

u russian?

desert niche Dec 5, 2022, 3:56 PM
