A real computer programmer said things like "DO 10 I=1,10" and "ABEND" (they actually talked in capital letters, you understand), and the rest of the world said things like "computers are too complicated for me" and "I can't relate to computers-- they're so impersonal".

In theory yes, but it's pretty hard to stay entirely self-contained like that.
You're almost going to want to link against libc, and bundling that really isn't the greatest idea. It could also be something large like GPU drivers, which itself is going to link to libc.

So you decide, "fine, I'll just let it resolve the system's libc", but then you've got the whole glibc vs musl vs whatever other alternative which probably aren't going to be binary compatible.
If you have some kind of container, you push the maintenance of that problem onto someone else who's probably already provided a "clean" environment for you.

But I still think containers are a meme most of the time. The real 999 IQ play is to not distribute your software at all, and trick other people into doing it for you, by making it as easy as possible to build.

How do I force myself to code before they fire me? It's COBOL btw.

I'm trying to learn C. I'm wondering whether there is a better way to concatenate a string and int before assigning the value to the member of a struct.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define NAME_MAX_LEN 64

struct cat {
    char name[NAME_MAX_LEN];
};

int main(void)
{
    const int count = 10;
    
    struct cat *cats = calloc(count, sizeof(struct cat));
    
    for(int i = 0; i < count; i++) {
        char cat_name[NAME_MAX_LEN];
        snprintf(cat_name, NAME_MAX_LEN - 1, "Cat %d", (i + 1));
        strncpy(cats[i].name, cat_name, NAME_MAX_LEN - 1);
    }
    
    for(int i = 0; i < count; i++) {
        printf("%s\n", cats[i].name);
    }
    
    free(cats);
    
    return EXIT_SUCCESS;
}

>>101350851
No need to call calloc unless you actively rely on values being zero (which you don't).
No need to call malloc either; the struct array easily fits on the stack (640 bytes ought to be enough for everybody).
And you can snprintf directly into cats[i].name without the temporary store into cat_name.

>>101350891
Thanks, Bill. I've fixed my code as you suggested. Would it be a retarded idea to dynamically allocate the space needed for the names instead of #defining it to be 64 bytes long?

>>101350851
>a better way to concatenate a string and int
Admittedly, I'm not too familiar with C to definitely say: I would've rolled my own implementation instead of using the standard library.
But for what you're trying to do, it looks good.

>>101351102
Depends on your requirements and competency. With a static size you're not only potentially wasting space if the strings are smaller than expected, but you're also limiting yourself to exactly that amount of bytes. On the other hand it never hurts to have a couple extra bytes on standby, and if 64 is the absolute max you will ever need ... why not?

Also, if the strings all have more or less the same lifetime, then you can use an arena rather than mallocing/callocing memory for every single string you store: https://www.rfleury.com/p/untangling-lifetimes-the-arena-allocator
You should avoid malloc/calloc in general: >>101343060

is there a reason I shouldn't just use huge static buffers for everything and let demand paging take care of memory management for me

>>101351368
-using much more memory that you need, or using not enough.
-no control over the allocation in the first place (different page sizes).

Interesting. I would've thought strcpy-ing from a static template would've been the better way to go.
I would've thought, that that'd be equivalent to

name = &"Cat ";

; but testing both out, yours works and mine doesn't.
I (partially) understand, why mine doesn't work; but why is your casting of pointers any different to assigning it an address directly?

>>101346280
It suck just use nim

>>101353074
Nim is too hard for most Pythonbabs

>>101341573
actually read the manual and finished paging
for the third time now

>>101351857
Yours isn't dereferencing either pointer so you are assigning a "derived declarator type" object whose value is an address, rather than the object being pointed to.

*(uint32_t*)name = *(uint32_t*)"Cat ";

"Cat"

evaluates to an object of type pointer to char whose value is an address that the compiler understands to be the location of a char-sized object. Note that the actual type of the string literal is actually char (*)[5] not char*, so this isn't actually correct but I'm simplifying.

(uint32_t*)"Cat "

tells the compiler to ignore what it thinks the type of this value is, and instead to treat it as the location of an object of type uint32_t.

*(uint32_t*)"Cat "

dereferences that pointer to an unsigned 32-bit integer and the expression evaluates to the object it points to.

(uint32_t*)name

does the same thing to the lvalue pointer. "Treat this pointer to char as a pointer to an object of type uint32_t."

*(uint32_t*)name

the complete evaluation of the lvalue tells the compiler that the evaluated rvalue expression, which is a uint32_t, should replace the current uint32_t value stored at (uint32_t*)name.
Also remember that arrays decay to pointers in (almost) every expression, so "name" could be a proper array, but its place in an expression is represented by a pointer to its first element. The array is decaying to a pointer as of being passed as an argument to the function anyway.

name = &"Cat"

would be changing the value of "name", an address, not the value of the object it points to.
Attempting to modify a string literal is undefined behavior in any case. It may work but every time the string literal "Cat " is evaluated it's probably the same address each time to the literal data in .rodata
The autist you're responding to has been going on about compiler string read/write code generation optimizations for weeks now.

Waste of time, it's like asking to read an old construction book that still tells you to use asbestos for insulation, we know better now. If you want to learn old techniques you should go look at things that were actually built in the time period you're interested in to see what people were actually doing, not what peoples opinions were.

>>101354390
I want subclasses to access it, I don't want the whole package to (really just for cleanliness at that point desu).
e.g. I have a class, it's important to set some specific variables if you extend it, those variables aren't known at the start of the constructor so I can't just slap a super(args) and deal with it in the base class constructor, this means either I need an init(args) that's visible to subclasses or I need the variables themselves to be accessible. Obviously I don't want either to be accessible to other classes.
From what I can gather my assumption of packages is wrong, they must expect you to create a package for fucking everything.

>>101354539
you are the only person editing inside the package, just don't access the things you don't want accessed. I know proper encapsulation feels cleaner and better, but... your package is yours man, you don't need to protect you from yourself

prototype it in python, i usually write stuff in Blender so I don't have to mess with rendering libraries
then port it to C++, this step is nice because you can refactor at the same time

>assign the actual uint32_t for the string
Oh, I see it now.
I've just tried using different casts (uint8_t, uint16_t and uint64_t), confused why I sometimes get "C" or "Ca", and I just needed to reread the explanations for it to click.

"Cat ", assuming char is 8 bits, can also be represented as a 32-bit integer (without the null-terminator).
What's being done is, that 32-bit integer's being copied over into the memory space of name.

>Attempting to modify a string literal is undefined behavior in any case. It may work but every time the string literal "Cat " is evaluated it's probably the same address each time to the literal data in .rodata
That was exactly my concern with

*(uint32_t*)name = *(uint32_t*)"Cat ";

, but I see now that, with all that casting and dereferencing, that's avoided.

Anyone have any tips for reverse engineering? I'm trying to build some development tools for a proprietary dbms (similar to Access) but keep getting tripped up by new discoveries. I change one thing and suddenly a rule my code is based on changes, tables are saved in mixed up order for every schema write to the file, etc.

Is there a better way to uncover all these besides stumbling over them?

scriptlet here, i need a bit of help structuring a loop (?)

i have a vertex, it has neighbours. i loop over the array of neighbours, get their positions, average it and that becomes my new position.
i would like to add a depth parameter. if set to 1 it does what i just described. if set to 2 includes the positions of the neighbours for each of the vertices in the neighbour array. if set to 3 it dives another level further.

how do i set it this up?

you want the average of nodes at level <=n (i.e. within n edges) maybe excluding 0

>>101356422
>>101356443
honestly its really simple, just keep a set of visited nodes, recursively go out up to N putting everything you touch in the set to prevent issues with cycles and accumulating total position for things newly added
then divide total position by no. elements in the set

I think you want something like this to start

total = verts[y-1][x-1] + verts[y-1][x] + verts[y-1][x+1] +
        verts[y  ][x-1]         +         verts[y  ][x+1] +
        verts[y+1][x-1] + verts[y+1][x] + verts[y+1][x+1]

and then add the extras like average/depth/etc

You remind me of Trump. You both refuse to acknowledge reality, no matter how many times you're being corrected.

is textbook "I was just pretending to be retarded".

Didn't ask but okay. I hate the guy too but you sound like him more lmao

You hate yourself? Makes sense.

Yeah, I've been fascinated by his total disregard for reality ever since his conviction.

git is retarded, private repository over the internet (aka own servers, own esstablishment) and doing manual backups

>>101358747
self-hosted gitea instance
if you really want to rely on something non-hosted by you, then gitlab
if you want to join the popularity contest or want to have the small chance to be besieged by some minority then github

Does gitlab require fucking money?

>>101358997
Yes

>>101358997
No service should require you to have sex with money.

not really, it's free but unless you require the epic devops features or some limit enhancement it's really not worth it for the average programmer
you can also selfhost gitlab as well for free with the community edition

Tomorrow reading about pci host bus programming in an old intel manual and writing a driver for it, which is probably pointless (mps only mentions apics being standardized in *that* way) but whatever

>>101359355
yes, from what i can tell it shouldn't be that hard overall
especially if you're doing it in a compute language with actual access to the hardware (i.e. CUDA, SYCL, or HIP)
i haven't been feeling well enough to really start start (COVID, everything fucking hurts) but i've been reading NES emulator info for a little bit in prep

>>101359447
that's something else, a monolithic shader that handles a lot of decisions dynamically, that's actually useful and is actually modern best practices as recommended by id
what i want to do is just fucking retarded but there are things i want to test that make it useful for practicing

>>101359652
actually scratch that is is a little bit like what i want to do in that it's handling emulation of the rendering pipeline with that style of shader
i must have skimmed over that bit when i first read that article a while back

>requires WSGI
So the best description I could find on how that works is https://ivory.idyll.org/articles/wsgi-intro/what-is-wsgi.html:
>it's similar to the CGI environment
That couldn't possible be true, right? There's no way that they launch a fucking process every single time a request comes in, right?!

>>101360923
of course not. It's more similar to fast cgi really.

>>101360957
Source?
And even if that's truth: that's still garbage because it requires communication with a backend server.

>two TDS retards arguing over nothing and accusing each other of being orange hitler
When are you guys going to admit you're over-integrating politics into your daily lives? You have a poor grasp of rhetoric and can't convince anyone of anything without trying to shame them. It's cope for having technical beliefs you don't know how to substantiate and, thus, a tenuous grasp on reality itself.

>>101361085
>two TDS retards
Why are you counting yourself into this?

>>101361095
I'm not. You're intentionally misreading what I said so you can continue deluding yourself into thinking your position is the normative one so you can try to shame me. You have to assume samefagging because the perception of ideological popularity is central to why you believe what you believe, and why you think other people should agree with you.

PROGRAMMING
Is there no way to explicitly access or use xmm/ymm registers on bare metal c/c++ without intrinsics and the STL?

>>101361391
I guess.

>>101361380
I'm primarily nocturnal just like a bat or your mother's employment.

>>101361487
You're both bloodsuckers?

>>101361391
>Bare metal
>C/C++
lmao
>without intrinsics
You can do inline assembly but that's probably harder.
You could also link assembly objects you write separately.
There's also Vector extensions in GCC which you might be most interested in.

>>101361525
No, your mother's a whore. I called your mother a whore.
See, this is why you should learn how to read, you'll pick up on more.

>>101361577
So you're both whores?

>>101361612
No, because nocturnal employment specifically is what makes your mother a whore, not merely being nocturnal.
You realize you have the reading comprehension of like a 3rd grader, right?

>>101361649
Sounds like you're a whore too ngl.

>>101361657
You have 80IQ, don't you?

>>101361666
I'm not the one who needs to whore himself out, unlike you.
