HeliumHydrideon How do I deal with memory leaks? (2022)

auto_ptr was effectively split into std::unique_ptr and std::shared_ptr. The problem was that before C++11, there wasn't a way to distinguish between copy assignment and move assignment.

"Listen, regardless of which Byzantine fault tolerance protocol you pick, Twitter will still have fewer than two nines of availability. As it turns out, Ted the Poorly Paid Datacenter Operator will not send 15 cryptographically signed messages before he accidentally spills coffee on the air conditioning unit."

HeliumHydrideon All 23-Bit Still Lifes Are Glider Constructible

You can make a Turing machine that contains self-destruct circuitry which destroys all moving parts upon halting. The resulting pattern will be a (pseudo) still life.

I don't know much about lighting, but looking at the source code of the shaders might give a clue. https://modrinth.com/discover/shaders has a lot of shaders that change the lighting. In other parts of the rendering pipeline, there are some very impressive mods utilizing GPU magic. One of them is Voxy (https://modrinth.com/mod/voxy), one that massively increases render distance with mesh shaders and level-of-detail based rendering.

HeliumHydrideon Branch Privilege Injection: Exploiting branch predictor race conditions

https://scholar.harvard.edu/files/mickens/files/theslowwinte...

"Unfortunately for John, the branches made a pact with Satan and quantum mechanics [...] In exchange for their last remaining bits of entropy, the branches cast evil spells on future generations of processors. Those evil spells had names like “scaling-induced voltage leaks” and “increasing levels of waste heat” [...] the branches, those vanquished foes from long ago, would have the last laugh."

HeliumHydrideon Hacktical C: practical hacker's guide to the C programming language

With GNU extensions, you can make a simpler coroutine macro without switch/case abuse:

    #define CO_BEGIN static void* cr_state_ = &&cr_st_0; goto *cr_state_; cr_st_0:
    #define CO_RETURN(x) ({ __label__ resume; cr_state_ = &&resume; return (x); resume:; })

HeliumHydrideon Make C string literals const?

They're not const because of backwards compatibility. Const correctness in C is a lot weaker than the way C++ enforces it, letting you implicitly cast it away in a lot of cases.
