>>32580 (OP)
I haven't read it, but from what I know it covers K&R C rather than ANSI C89 (or ISO C90, which most compilers implement and call C89 or something). If you don't know or understand C very well, it may be worth the read.

Otherwise I'd recommend reading The Art of Computer Programming by Donald Knuth, specifically the first volume. It teaches you the fundamentals of trees and useful manipulations you can apply to them. It teaches these concepts in an ancient hypothetical punch-card programming language called MIX. You are provided nothing but the absolute bare-minimum. The assembly language still provides a great deal of meta-programming through homogeneity of instructions and data, but this concept isn't as useful as it once was. Still a very interesting and insightful read.

Newer volumes of the book should come with instructions in MIXAL instead of MIX, which is far closer to modern systems running AMD64/AARCH64.

Why would you want to learn an outdated and frankly inferior iteration of C? Who the fuck would want to write K&R parameter lists or put up with the retarded compiler constraints of that era?

That was my point. Learning K&R C when no compilers exist for it is kind of pointless.

i just switched from the google search engine to duckduckgo and so far i liked it, it does not have the gorillions of ai slop google has to offer, the search is okayish and i can work with it. unlike google, they dont force the ai shit onto you, even by default, but what are the cons to this search engine apart from the maybe occasional worse searches?

If your issue is privacy, your search engine matters less than how you browse.

You cannot trust anyone tracks you less than say, Google; you have no access to verify server side code. Therefore, privacy burdens remain on you

I feel like the stack is so mystified because the professors teaching it don't understand it or anything low level themselves. I say this as I am just beginning to learn C
<tech space
When a function is called, a section of memory is "reserved" on top of what is called the stack. This section of memory is the function's stackframe. The stackframe contains all of the variables allocated by the function. The stack is made up of stack frames.
<tech space
After you understand this, the rest is easy. If you want to remove a variable from a stackframe, it has to be both a variable from the frame on the top of the stack and the variable on top of that stackframe.
<tech space
Pushing something to the stack is just adding something to the top, and popping is just removing the top item. You can't push or pop any random item. The top of the stack is just a pointer in a CPU register. Popping simply decrements the top stack pointer and pushing simply increments it and stores a value at said address. The list of elements in them are entirely defined by those registers. There is no such thing as removing a value within these bounds. You can write it to be zero, but you can't just remove it.
<tech space
I think the plate analogy is almost a misnomer because it's easy to visualize but it's easy to forget this fact. You can't remove something from the middle and have the stack collapse on itself.

i understood all of that before.

and if i am right in functions local variables are stored on the stack as well so that they can be modified via popping them to registers or moving something to %rbp + offset (which is a multiple of 4 or 8 depending on the system)

also
the reason why you don't return a pointer from function is because after it's stack frame is done and %rbp and %rsp are reset the address stored in the pointer will now point to the undefined region in memory (evendoe the data in it may still persist for a brief moment) which will make the os throw a segfault. very interesting stuff really about the scopes and variable lifetimes, be careful when returning a pointer.

>>32599 (OP)
It is wild that most programmers fundamentally don't understand the machine they are working with. If you don't understand the stack, heap, fragmentation, pointers, and the primitive data structures constructed of only the previously mentioned things (especially trees, lists, and arenas), you are NGMI.

It is as if we went from having mathematicians to replacing them with people who can use calculators, and calling themselves mathematicians.

Chud 05/30/26 (Sat) 00:54:02 №32636

bump, let's talk about the heap

Chud 06/01/26 (Mon) 06:44:17 №32777

So garbage collection is just going back through the stack and reassembling based on what is still in context? So what happens with manual memory allocation and deallocation? I do infra work and Elixir I never got into C but intend to once I start on my Z80 build

Chud 06/01/26 (Mon) 06:59:44 №32778

>>32777
I think garbage collection mostly has to do with the heap

Chud 06/01/26 (Mon) 11:21:56 №32791

>>32777
when function call ends, stack frame "clears" automatically, we go back to previous %rbp. The data is still there, but it will be overwritten by other stack frames.
Garbage collection refers to automatically deallocating allocated memory on the heap. In C, there is no garbage collection, instead you have to call malloc() and then free() to free the memory. If you don't call free(), there may be a situation where your program repeatedly calls malloc(), causing it to allocate memory more and more, never disposing of it, swiftly devouring your RAM. This is called a memory leak. In languages like Java the dynamically allocated memory will be disposed automatically by a garbage collector. In V language there is memory deallocation at compilation time, or something like that, I think it automatically injects free() where is needed, o algo.

BSD 'teens Chud 05/30/26 (Sat) 14:48:05 №32660 [Reply]

Are there actually any 'teens out there that actively use any of the BSD oses? (FreeBSD, NetBSD, OpenBSD)

I know the wiki likes to sing it's praises but I've hardly seen discussion about it on here.

Honestly, I don't really see much reason in using BSD when Linux exist but maybe you guys can convince me otherwise

Chud 05/30/26 (Sat) 17:27:09 №32662

There's no reason to use BSD unless you were already using it for some reason, or you're a corporation who's scared of the GPL.

The advantages of FreeBSD that people claim (ZFS, jails) already exist on Linux in the form of OpenZFS w/ DKMS and containers.

Some people will say OpenBSD is "more secure", but the thing is, attackers attack your applications, NOT your OS. The same Postgres/PHP/nginx exploit will work the same on every operating system no matter how souped up the security of your BSD is.

MAYBE NetBSD has a very niche use case if you're running it on some ancient SPARC/MIPS/whatever toaster from the 90's that isn't supported by modern Linux.

An attacker would need RCE to exploit this vuln anyway. And if an attacker has RCE then you’re toast anyway.
That is unless you have a strict, enforcing SELinux policy. Which BSDs don’t really have any equivalent to. In OpenBSD pledge exists to limit syscalls. But the application has to be patched to support it, which no one bothers with (even for the most popular software), so it might as well not exist.
