Just report and ignore it. Hopefully the janitors will finally get off their ass and do their (unpaid) job.

Plotting audio input live with PyQTGraph:

This graph stops plotting after a while. The time it takes varies. Does anyone have a clue as to why? No error codes or anything.
Also feel free to point out any retardisms in the code.

Jesus, why did you write your C code in such a retarded way?

What is this supposed to be showing

wrong thread

What's the best language for making a fighting game

2D -> C#
3D thots -> C++

that your compiler loves you

also: HOW do I exit the program properly? I have several identical processes listed in htop after doing ctrl+c and closing the window

turns out compile time is actually pretty important, and sepples mongs have been rediscovering it.

not by default

just force it

it's a two-way relationship, you can't expect it to do all the work

talk is easy. show me better kode.

>HOW do I exit the program properly
import sys
sys.exit()

or just use SIGINT OR SIGTERM

just killall

print("please write "sys.exit()" below!")
cmd = input()
eval(cmd)

cheers

int *tmp = realloc(arr, sizeof *tmp * cap);

arr = tmp;

arr[len++] = n;
}

qsort(arr, len, sizeof *arr, compare);

if (len != 0)
printf("%d\n", arr[0]);

free(arr);

}
If you were really trying to squeeze out performance, I would look at replacing qsort with something hand-rolled.

Not all wagies are idiots, but you seem to be.

np buddy

size_t partition(int*A, size_t p, size_t r) {
size_t i = p - 1, j = p, pivot;
int temp;

pivot = p + rand()%(r-p + 1); //random pivot

temp = A[pivot];
A[pivot] = A[r];
A[r] = temp;

while ( j < r ) {
if(A[j] < A[r]) {
i = i + 1;
temp = A[i];
A[i] = A[j];
A[j] = temp;
}
j = j + 1;
}
temp = A[i + 1];
A[i + 1] = A[r];
A[r] = temp;

return i + 1;
}

void quick_sort(int* A, size_t p, size_t r) {
size_t q;

if ( r > p ) {
q = partition(A, p, r);
quick_sort(A, p, q > 1 ? (q - 1) : p);
quick_sort(A, q + 1, r);
}
}

why is my quick_sort about 4 times slower than my heap and merge sort (who gets almost the same time?)

>//random pivot
That's not a great idea.

I said better not code review-tier garbage

it's the same time with or without it

if(modalWindow.Viewmodel.BoundContent.Datacontext.Viewmodel.BoundContent.Datacontexg.Viewmodel.GetType() == ModalWindowGenerator().GetInstance(ModalWindowTypes.WindowINeed.ToString()).GetType())
God I love OOP

What the FUCK is a microservice

Sounds like a fancy way of saying this binary only handles a crumb of crud

>pop() in C++ is void
Why tho

The "quality" (closeness to the median) of the pivot is vital to quicksort's performance. If you happen to pick the lowest/highest value, the performance will absolutely tank. So often the pivot is picked as a middle of 3 values, so you never hit that worst case.

Also, quicksort actually sucks for small arrays, as the overhead is high. Many "real" implementations will change algorithm when the size of the list is too small or has recursed too far, usually to something like heapsort, which itself becomes a new algorithm called introsort.

>delete this thing and then give it to me
See what is wrong?

Sometimes you don't need the result, there is a returning version as well with a different name

pretty much, crazy how UNIX had it all figured out decades ago.
I really like erlang/elixirs approach though.
You just group child processes under a supervisor. Where I think other languages have to nig-rig their own supervisor structure.

Rate my new move:

If you are inflicted with damage over time effects, or debuffs you clear them, and regardless of your DoT status, you deal damage equal to 1/2 of a standard attack range.

It would be the attacking equivalent to a healing move which removes DoTs and debuffs as well, healing for 1/2 of a standard heal range.

Some damage over time effects in my game can defeat a fighter in three turns, but given the ability to heal the effects off, the battles would often stalemate with the DoT being cast over and over, while the other one cleanses it away. With a damaging version, at least now people have the option to go for a Pyrrhic victory instead of getting stuck.

It was easy to add it, because my code is extensible, all I had to do was add 1 more case to a switch.

>microservice
how would you define microservice?

anyone got an explanation or uses for the liskov substitution principle? what's the point of extending through subtyping if you're ultimately bound by the same requirements defined by the base type? If we have, for example, a File object with a read() method returning the file contents, and subclass it as 'HTML' with the read() method returning its contents converted to html, does that respect the LSP? If so, how? After all, program parts making use of the object might expect the output to not be html.

>liskov substitution principle
is more about data layout than what the object actually does via virtual methods

The derived object can override those methods

Programming is boring

a service that does exactly 1 very small thing.

how do i edit a lisp file while its running?
I tried "sbcl --load file.cl" and edited it in nano and saved but its not working

it's almost like you can't just spend all your time on hackerrank/leetcode or grinding books. And you need to actually apply concepts and make projects.

In theory something small.
In practice systemd

you're boring

*except in C++

yes

what programming?

achieving things is rewarding

is wifi also bad for me?

Yes. Given that it operates at 2.4-2.45 GHz, which is near the maximum dielectric loss of water, where it begins to spin on its axis, that alone should give any sane human being saying it's inert pause. Microwave ovens use this to cook food for a reason. Just because it's below the threshold of ambient thermal noise, doesn't make its basic properties change.

Altered calcium flux and all the rest of it also applies.

>Just because it's below the threshold of ambient thermal noise, doesn't make its basic properties change.
No, but that does mean you could never notice any consequences. It's so miniscule it's virtually not there.

Does C++ have dynamic typechecking?

with std::any sure I guess

It does not mean that. Biological systems are designed for transduction and amplification of a broad range of polarized or periodic signals, and electromagnetic signals are part of that.

Would you kindly fuck off to your own thread and leave dpt?

No actually, they aren't. That's a meme. 100% of signal transduction in humans is chemical.

>How does vision work
It's time to stop memeing.

Motion of charge in the extracellular space->field created->forces put on charge groups comprising calcium channel voltage sensing subunit->channel activation->downstream signalling

This is not a chemical mode of signalling. Cells do this all the time on their own. That's how they work.

Nah I'm done, you don't know enough to even argue with.

Vision involves light, ie, radiation. Which is not "100% chemical transduction".

Also, look further into dark current and the dedicated pathway to the pineal gland. I'd recommend the book "Electromagnetic fields and circadian rhythmicity."

what about this?
sciencealert.com/neuroscientists-say-they-ve-found-an-entirely-new-form-of-neural-communication

>Scientists think they've identified a previously unknown form of neural communication that self-propagates across brain tissue, and can leap wirelessly from neurons in one section of brain tissue to another – even if they've been surgically severed.

>always use events in C#

>switch to weak references

Is there any reason to use the former over the latter?

The skin is a massive mmWave transceiver. Ancient knowledge as well, "the right hand gives, the left hand receives." Indeed. The right hand voltage gradient is positive, the left is negative. This is how healing by hovering or laying of the hands works. Modern day millimeter wave devices are still used medically in Eastern Europe.

How do I get better at programming?

learn Haskell

Haskell is sexy but unfortunately just not worth the investment and overhead.

why did you bother asking if you didn't like the answer
also there's no overhead compared to Java or C#, what you mean is compared to a very small number of languages (C, C++, Rust), and nobody said you'd have to continue programming in Haskell

How would that make me better at programming?

you'll learn things you wouldn't learn doing most other languages

It's not a coincidence genius prodigies prefer Haskell.
