The Real Relationship Test: Centering A Div

Ah, JavaScript's type coercion explained with toilet paper. Pure genius. Non-zero value: Has toilet paper. Works as expected. 0: Empty roll but still there. Technically exists but utterly useless. null: Just the holder. Someone deliberately removed the toilet paper. undefined: No toilet paper holder at all. Whoever built this bathroom forgot a critical component. And yet somehow all of these evaluate to false in an if statement. JavaScript, where the rules are made up and the types don't matter.

Content Ijust wanted to add to this discussion that I am just compiling on VS and GCC, and used to use include guards. I have now switched to pragma once, and the only reason for me is not 199 performance or portability or standard as I don't really care what is standard as long as VS and GCC support it, and that is that: pragma once reduces possibilities for bugs. It is all too easy to copy and paste a header file to another header file, modify it to suit ones needs, and forget to change the name of the include guard. Once both are included, it takes you a while to track down the error, as the error messages arent necessarily clear.

Forget performance--we should use pragma once because it's less error prone. It occurs to me that if compilers are already tracking include guards, they're already doing most of the work necessary to issue warnings when they see different files using the same macro name. - rieux Jun 13, 2019 at 6:36 Add a comment pragma once has unfixable bugs. It should never be used. 169 If your include search path is sufficiently complicated, the compiler may be unable to tell the difference between two headers with the same basename (e.g. afoo.h and bfoo.h), so a pragma once in one of them will suppress both. It may also be unable to tell that two different relative includes (e.g. include "foo.h" and include "..afoo.h" refer to the same file, so pragma once will fail to suppress a redundant include when it should have. lanc arca attocic tho commorc amia

Content o) SUNDAY Hi, M , the website looks great! But just one thing, since my store is about cosmetics, could you please add the image of a mirror for the background? That way when customers go to the website they will be able to see themselves and this might help them make a better choice. It would be more interesting. Thank you! 15:28

Ah, the eternal cycle of library addiction! You find that shiny new package that solves all your problems (or so you think), and suddenly you're evangelizing it like you've discovered fire. Meanwhile, your codebase is already a digital hoarder's paradise with 1000 dependencies, and your coworkers are plotting your "accidental" deletion from the Git contributors list. The best part? Next week you'll be doing it all over again with another library because clearly, the solution to dependency hell is... more dependencies!
