I'm far from an expert in baking systems, and I've learned not look down on domain knowledge — building a system that can actually be used always requires much more effort com...

The typical conversation here: === 1 === - Hi all! - Hi! === 2 === - I'm new to this, what should I do? - [a stackoverflow URL of good quality, which can be easily obtained ...

Q: Is it a bug? A: Yes, it can be categorized as buffer overflow vulnerability. Q: Why doesn't it crash? A: Dereferencing wild pointer is like opening a box of chocolate, yo...

Well, that's a little hard😂 #include <stdio.h> #include <stdlib.h> #define L(x) long x #define M main #define R return #define A atoi #define C char #define P(x) printf("%c",...

Build system? My experience is limited to a few traditional systems: * Autoconf: very powerful, but the scripting system easily gets you into trouble * Make: crude. Suitable...

Which compiler? AFAIK, GCC and Clang write their own parser from scratch. What PLs official implementation use parser generator? IIRC Bash, PHP. Either old-fashioned or home-m...

As what I written before. If you can help, do it by guidance (just like my screenshot). If you can't, no matter for what reason, just keep silent. Except you are the person wh...

Anybody know groups without beginner questions? Kinda tired of "how to learn X" / "A or B better" / "which IDE" / "won't compile". I can find gems, but most of the discussion...

i remember there's a heavily optimized industrial-grade data structure library, which claims being faster than skip lists in most situation. the strategy is switching to tens ...

BTW, after browsing the problem list, I find this problem especially interesting. https://www.codechef.com/ISCC2017/problems/SEQUA I consider using group theory, and in thi...

What if the check is only used for friendly user interface? In this scenario, the password is actually used for decrypting data. (Consider TrueCrypt and p7zip for example)

What's this? Much better than GDB

Have you observed that SUM(i^i) mod M = SUM(((i mod M) ^ i)) mod M ? it's periodic!

I don't think CFG allows you print hello world — it's a formal representation of a class of sentences, anyway. Are you attaching actions to the parsing process?

If a language uses "#" for line comments, and the other syntax elements are identical to C++, would you call it C++?😂

very eye-opening! how did you know such thing? is there a portal for related topics?

What about the Java way -- making getFoobar() virtual?

For the compatibility of some weird platforms?

Don't know🙈 Could you point it out?

Could you share which channel they are?
