What are you working on, /g/?

Previous thread: >>105530074

good morning sirs

!!! PSA !!!
/dpt/ is infested with homeless schizophrenics and the governance (jannies) are useless as per usual.
Please resist the urge to engage with the feral spammers. It is unsafe and you risk contract their diseases. In order to identify them, look for:
1. malloc/mmap sperging
2. registry dumping sperging
3. bitch replying without quoting (passive-aggressive effeminate activity)
4. screeching at the thought of someone doing something for fun

Thank you! Please use /dpt/ to engage in actual programming discussion

AVX is now banned from my projects just to make this tranny seethe.

While getting filtered by OOP usually results in code being static and procedural (ie. an "avoid OOP at all cost" approach to writing code while using an OO language), it's even worse when someone gets "half-filtered" by OOP and starts applying inheritance haphazardly, especially to cases where it has no place.

>>105570819
Inheritance has no place in programming at all.
>See this shitty code written 20 years ago?
>Yeah, all new code should inherit this slop.

>>105570829
It does, but not everywhere.

Code age has nothing to do with it. I work with an enterprise application that has literally 20+ year old APIs and patterns, but they were written by smart white people so it's all excellently solid and stable - you can completely ignore how they work internally and just focus on providing them parameters with the right inherited interfaces.

Threadly reminder.

>>105570886
Yes it does, code written 20 years ago, unchanged, is likely obsolete.

>I deliberately make my code suck just to make other people mad
Who gives you money to survive?

>>105570902
What drives you to such a conclusion?
Have you ever worked with a well-designed codebase?

>>105570986
The fact that software that's relevant, gets updated.

>>105570991
The software I work on is very actively updated, if that's what you're trying to hit. The point was that the interfaces are very well designed and don't need to change, even if the implementation does.
Surely you have picked up on this and aren't another one filtered by OOP or software architecture.

>>105571044
>the interfaces are very well designed

Good afternoon, Ada chads.
Reminder that soilangs don't have a LOLITA.

>>105571044
Software written 20 years ago was designed for computers that don't have SIMD.

>>105571153
Utilizing SIMD is a low-level implementation detail

>>105571200
Retard.

>>105571200
Which doesn't happen automatically. My naive substring search outperforms strstr by 300%

>>105571220
And when using your substring search, do you need to provide SIMD-related details, or is that all "under the hood" and you just call it with a string to search through and a phrase to search for?

>>105571311
>do you need to provide SIMD-related details
Yes.

>>105571311
Yes, I need to call my own function and not strstr, that function must be somewhere in my code.

#include
#include

int
main(void)
{
char user_input[128];

printf("Enter string: ");
fgets(user_input, sizeof(user_input), stdin);

size_t len = strlen(user_input);

for (int i = 0; i <= len; ++i){
if (user_input[i] >= 'a' && user_input[i] <= 'z'){
user_input[i] -= 32;
}
}

printf("%s", user_input);

return (0);
}

Christ, /dpt/ is yet again filled with incompetent autismos.

>>105571449
Clearly you don't understand if you are pointing out checking char for char as an error when you have to in order to check for not char ascii values before attempting to subtract 32 from them as an error in that code.

But, like I said, I accept your concession.

>>105571526
Just making sure, but when you talk about triple digit IQ, you don't believe that you're part of that set, do you?

>humiliated
Back to projection again, Ivan? But then again incompetent autismos are not capable of feeling shame, so at least your behavior makes sense.

>>105571741
Spend like 30 minutes cloning the source code.
Change one trivial line of code.
Spend the next 12 hours compiling it (this isn't as much of an exaggeration as you'd think it is)

So ez, just annoying.

Well, I wrote the code, it works, and I'm laughing at you - so, yes, I AM part of that set, and you can do naught but cope and seethe about it.

I accept your concessions.

>>105571819
what use do you have for extra time? you don't do anything.

>>105571835
Considering your response to my post, your brain also doesn't do anything, including existing.

>>105571845
I accept your concession :(

>>105571809
Yours works by having to iterate through the string (the strlen, which has a good chance of loading your string into AVX registers) once, so that you can iterate through the string again (but this time character for character). If you were smart you would load each part into an AVX register, perform conversion and NUL-byte check, and write the data out again without any further memory references.

>>105571853
Do the math of 5ms times billion once the science foundation that you donated your brain to before you were done using it decides to give it back to you, and you MIGHT get the joke, retarded spastic.

>>105571859
For someone supposedly so intelligent, you sure ignored the option of not using fgets and using something that makes finding the total string length in bytes trivial.

>>105571859
By smart you of course mean learned.
You should probably start making this distinction at some point in your life.

>>105571867
>long sentence

>>105571885
Well sure, you have to get your brain back first.

>>105571873
Doesn't really matter because generating the mask and counting trailing zeroes is trivial to do in the AVX domain.

>>105571876
You already had the chance to *learn* it by looking at >>105571427. The fact you didn't means you're not *smart*. QED.

>>105571934
You should have learned electrical engineering before touching ASM, but you didn't, why?

He will either leave programming entirely (which is good), or he will have learned to avoid memory references (which is also good).

Are those

in the room with us now? Or are you just being an incompetent autismo again?

>>105571953
Because litography has nothing to do with that, computers are toddler grade circuits that can be assembled by anyone (except redditors like you who put the CPU into the socket backwards and bend the pins I guess).

Next step, port queue code to Rust generics. Port printf code to use Rust macros.
Can't stand reading my own C code and more and don't want to deal with C++.

>>105572211
if rust does the programming for you you arent really a programmer

is it normal when you're first learning; to type so many comments that you can read the cunt like a book?


otherwise I go back the next day and completely forget what the fuck I've written

>>105572050
Lithography is a combination of various disciplines you fucking retard.

>>105573730
its ok i guess

>>105572211
You should be using Hare.

>>105573730
Does it matter? Whatever helps you learn and retain you should be doing.

>>105573768
I just never see verbose comments on code it's always jut a vague description 'this function returns a string for something else' and then a bunch of random shit.
Just wondering if there was a reason for that or if it's just autists forgetting that other people can't read their thoughts.

>std::forward(args)...
holy fucking bloat. imagine passing a bunch of parameters without having to chant some unholy incantations.

did some factorial in java, now its on to htdp

>>105573795
OpenBSD requires both grammatically correct and verbose commenting in it's official binaries.
That's why it's the home of the white man.
But yeah, I'm sure your comments will increasingly become less verbose as you progress and the people reading them will be at the same or higher knowledge level, so it won't matter to them either.

When you're learning commenting is good. Both for the reason you stated, it helps with remembering, but also the act of abstracting what you're doing in concise language helps with retention.

ok just checking because I thought I might just be a retard and unable to remember more than a few days into the past.

string hello="hello"
//this code is declaring a string, which is a sequence of characters in the english language, unless you're russian or smth idk. anyway back to the story, its stored in a variable of string type and like, its called 'hello'. that's set equal to the actual words and shit you need to store in the 'hello' box. in this case that thing what needs to be stored and that is called "hello". Hope you had a nice day.

>>105573730
comments that rich mean someone is struggling to even look at code

>>105573795
verbosity aside, good comments should explain purpose (the 'why', not the 'how')
the 'how' is described by the code. the comments should complement, not duplicate code

>>105574215
Sometimes I write some shit and then look at it and go 'why is the syntax like that'

so im using the comments to drill in that this is what each thing in the line does. so hopefully it goes into my brain.

I just started learning last week, so it's not like this is going to a dev team to maintain

>>105574215
>>105574255
I want to add that I'm not good at following code through visual studio or recognising what the fuck anything is.
so I'm using comments to annotate it like a diagram.

>>105570523 (OP)
>try to learn rust, "Requires visual studio C++"
Is the Visual studio C++ thing just for windows?
this language is for shitty codes who need guard rails and are unable to learn C++ so they learn this language.
>>105572211
>don't want to deal with C++
exactly what I am talking about. What is it you don't like about C++ the pointers? Its just a memory address? The Arrow for streams? If you learn C++ every other language becomes EASY. Don't give up on that.

This Rust vs C++ war is garbage. It uses C++ on windows. idk about Linux, It looks cool but I have to jump through so many hoops just to debug. Learning C++ std lib, and windows.h is a bigger payoff. Even script kiddies use windows.h

In light of the whole xserver shitshow, is it still a good idea to write your own x11 window manager

>>105574537
You can't just fork open source software chud

>>105574692
I'm just worried people might call me a "chud" if I make a window manager using "le old and outdated and now problematic" x11
Granted, I'm not using the autistic fork that's been causing controversy cause imo x11 is good as is

That is code cuckoldry.

Who cares, as long as jeets aren't getting paid either for stealing your code? Or what, does being a BSD-license cuck suddenly put food on the table?

Sounds good to me. We've regressed in the last thirty years.

>>105575405

dunno shit about qt, but i would guess it has something similar to Tk's textvariable option to bind a widget to another object and changes will flow back to it. ie. you change a string variable and all the labels bound to it will update without you mucking about with their paths.

On the other hand it's not like alignment is really needed since most memset implementations don't even try to store the values with NT hints ... but still, VPXOR and VMOVNTDQ are trival to implement, yet sepples STILL believe their nonsense is superior to C.

Rust learner here. I have written some baby CLI projects and talked about Rust in /dpt/ before. Also, I am about to start chapter 17 on the web version of The Book. It's the Fundamentals of Asynchronous Programming chapter.
This chapter is not in my physical copy of the book, so I guess it was considered important to update the web book to include it right after chapter 16.
I will finish this chapter today because it for sure seems to be important, but I was wondering if, after finishing this chapter, I can jump to the final project and then drop the book?

How important are the contents of chapters 18 - 20?

But there's no rule that you can't jump into the project right now. If anything it's probably a good thing to start working on it as you work through the book. Any gaps means you can revisit that section, or even learn it from somewhere else. Some books are good at teaching one thing but bad at teaching another.

Of course, as one of you said, especially on books like programming books, lots of times I just skim through contents and come back to earlier chapters if needed. It is not like reading a novel or something like that. But I still at least try to read from back to back.

How do OpenSSL manages to sign RSA in 0.006s?

Standard C library has 0 useful functions and half of C's features are worthless on top of being overly obtuse, of course C's creators are morons. And you are a moron too.
Just look at this faggot, his C code is slower than Python that just imports OpenSSL. This is how bad C is without discarding 99.99% of what constitutes C, and writing half of your code in assembly.

It's got a few useful ones, like memcpy(), but that doesn't mean it has a lot for doing RSA signatures.
The most useful thing for that tasl is a bignum lib.

My fellow code monkeys. Performacelet here. I've built a little program that draws some particles n sheet. It's all nice and multi threaded and works pretty well but I was wondering if anyone could answer why allowing Go to use all my cores generally gives me a bit lower but more consistent frame rate than limiting it to 3/6 cpu cores, which generally gives a bit higher average frame rate but has spikes up to frame rates that are like 50fps higher (sometimes holding there) than using all 12 (6 + 6 hyperthreading)? All the reading I've done the advice generally seems to 'just play with it' to get the desired result with very little concrete reasons to why it is like this?

>>105585751
>like memcpy()
Lol no, it's interface is way too generic: >>105579224

>>105585767

Found the issue.

On a lower level: synchronization and context switches.

>>105585803
Sweet, thanks for the resource. Go's performance has surprised me a little. I did a single threaded version before this one and it was around 90% of the speed I got out of C. A C skill issue yes, but still kinda surprising given it was basically the same line for line and a language with a GC + Runtime could get so close.

>>105585833
It depends on what your program is limited by. If most of your time is spent in the kernel, and you don't or can't optimize that out, then naturally both languages are going to perform similarly.

>>105586479
size_t is just a typedef for an unsigned integer that is large enough to represent the max size something can be.
Or more practically, 32-bit on 32-bit systems, 64-bit on 64-bit systems.
It also gets used for array indicies because the max possible array index is the same thing as above.

You have to define "C", because majority of "C" code is slower than JavaScript due to v8 devs actually giving a fuck about performance unlike cniles who think that writing a plain char by char for loop is enough in 2025 because "muh C is faster than Javascript" (self evidently isn't when you're retarded).
Cniles, when encumbered with JSON, write their own or download slowest parser they can find.
JavaScript programmers benefit from Daniel Lemire's parsing gigabytes of JSON per second, without thinking about cniles or how difficult JSON is to parse.
You clearly aren't competent enough to write fast code, stick to JavaScript, that way your code won't be slowed down by your retardation, because it was designed with retards in mind.

To add to that, Node.js 18 moved to pic related, and remember, cniles tout libcurl as holy grail.
>parses json faster than cniles by calling one javascript function

Why don't you show us what libcurl function they use, and then I'll show you where it fucked up?

>>105588427
Surprising that a hyper autistic url-parser is faster at parsing urls than a swiss army knife.
Nobody associated with C could have predicted that tools which do one thing well are really good.

>>105588456
Why don't you clone curl repo and figure it out yourself because I don't give a fuck about your schizophrenic opinion.
>>105588452
Yes it is, now post your own parser and tell me what pic related would look like if we added your Dunning-Kruger code benchmarks to it (I am not hopeful at all, don't sweat ever responding at all, retard).

>>105588477
I can sleep fine knowing that the benchmark is false and that the Ada people are lying. Can you?

>>105588477
Why would I write my own JSON parser when I can just use yy for free, you absolute inbred. PLEASE take your medicine.

>>105588473
That hyper autistic parser is used by Node.js, making generic JavaScriot faster than anything that uses libcurl. Think about that for a moment, hopeless midwit.

I have gone to a forbidden wonderland in memory? It just keeps going.

template
void foo(T t) {}

f(5);
}

int main()
{
// bar(foo); // doesn't work, fails to deduce template at call site
bar([](auto a){ foo(a); }); // work, deduction deferred to bar
}

Any way to avoid using lambda at call site? Calling bar(foo) is not an option as the real code is more complex and uses multiple types.

fetch window property with XGetWindowProperty.
if it's some special struct property, you can cast it or use a convenience function
if the property has an 8 bit format, it gives you a nul-terminated char*
if the property has a 32 bit format, it returns an array of 64-bit elements with random garbage stuffed in the high 4 bytes.
