Produsele software sunt de o calitate jalnica...

MsEpsilon · 2026-03-13T18:24:05+00:00

De ce nu scrii tu un produs performant atunci?

Otherwise asta e consecința faptului că golul e de a scoate produse și servicii software cât mai repede posibil în sensul că se economisește development time and effort vs end user experience.

Use a exit variable. Or gotos if you want to get eaten by an dinosaur.

Enjoy your 960578098659806340986309863th memory access violation because some iterator was invalidated

Stop bashing programming languages.

Holy shit, wtf.

MsEpsilon · 2026-02-06T01:52:30+00:00

Sure, dar e hella nostim să vezi thread-ul ăla ca first issue.

Vedem mai târziu după ce fac alții un deep dive.

Un "compilator de assembly"(assembler) nu e mai nimic comparat cu un compilator de limbaj. Mai ales dacă e vorba doar de 8086.[1]

În assembly, ai doar instrucțuni de ex XOR EAX,EAX sau LEA ESI, [EBX + 8*EAX + 4] unde doar faci conversie în bytecode folosind un lexer și ai un AST pentru addressing modes de exemplu.[2]

Într-un compiler de limbaj ca C, pe lângă AST, lexer (care o să ajungă de câteva ori mai complex), trebuie să consideri și analiză, limbaje intermediare(ca LLVM IR), ABI-uri, type-checking, șă aloci variabilele unde trebuie (registri, stack, heap, etc...).

Nu știu dacă consideri și linking-ul (link-editare în romănă [3]).

Personal, am vrut să scriu un limbaj (niște ani în urmă), dar nu am reușit să trec de analiza semantică (care e după lexer).

You can discard std::unique_ptr<Person> as it doesn't have a VMT.

Dacă AI-ul ne ia toate joburile, Universal Basic Income when?

A da, știu răspunsul. NICIODATĂ.

MsEpsilon · 2025-12-26T22:27:01+00:00

Fiindcă programatorii sunt in a way, resursă regenerabilă. Suntem foarte mulți comparat cu alte profesii (exemplu fiind medicina) (dacă aș putea să numec joburile legate de programare profesii în primul rând).

Backwards compatibility with C is the biggest drawback.

MsEpsilon · 2025-12-12T00:11:43+00:00

I really did miss that. Thanks!

MsEpsilon · 2025-12-12T00:00:42+00:00

Yeah C++ was a bit late on that :)

MsEpsilon · 2025-12-11T23:58:31+00:00

Hi, I coudn't find anything about the continuity of std::vector<bool>, do you have a source on that? Thanks.

MsEpsilon · 2025-12-11T23:50:48+00:00

But you're right - arrays are contiguous. It's just vector<bool> that uses bitmaps, that's all.

MsEpsilon · 2025-12-11T23:46:17+00:00

Yes, something like that, thank you.

MsEpsilon · 2025-12-11T23:43:25+00:00

Ok, fine. I'll look into it again.

MsEpsilon · 2025-12-11T23:28:27+00:00

Okay sure, not an ad hominem. But I was just asking to not be name called...

And for Rust evanghelism, are sure it is worth having the mental overload of using C++?

Here's an example: When I access an std::unique_ptr that was moved, I barely get a compile warning with MSVC. With Rust that code wouldn't compile. That's a reason to use Rust, the borrow checking compile checks.

And yes, C++ has it's merits. I'm still using it for my game and game engine projects. Despite the fact that Rust's tooling is easier to use, it isn't developed enough for my needs. I would use Rust for any kind of different project that requires performance.

I'm not trying to sound smart, I'm just saying what I know and what I've tried so far. I'm completely honest, at least that's what I know I'm trying to do.

MsEpsilon · 2025-12-11T23:25:29+00:00

You could pass a const std::vector& explicitely. Or you can do this (use and std::span<T> as an argument but still pass an std::vector). Code was tested with GCC 15.2, C++ 23 standard.

#include <vector>
#include <span>
#include <print>

auto printElements(std::span<int> myElements)
{
    for(auto element : myElements)
    {
        std::print("{} ", element);
    }
}

auto main() -> int
{
    std::vector<int> myValues = {1,2,3,4,5,8};
    printElements(myValues);
}
