The maximum safe voltage for this particular CPU is 1.4V I believe.

I wouldn't recommend it for cpu's that aren't unlocked.
I have i7 4770 (not the K version) and whenever I overclock it, at some point during the day Win' freezed.
Then it had some strange "fading away" effect that Win' kept freezing the next days or two (after I stopped overclocking) and then it turned back normal.

A friend of mine who helped me with overclocking asked me whether my CPU had that K-label or not and just told me to not do anything about the CPU since it didn't have one. I can't touch anything to do with the CPU in MSI Afterburner anyways but I'm sure there's workarounds like Kaperstone mentioned with his case.

You're right - just because your CPU doesn't have a "k" in it's name doesn't mean it's not overclockable.

The "k" chips are made with overclocking in mind, whereas the non-k chips aren't (theyre meant to run at factory freqs). There are a lot of steps you can perform for safely overclocking a non-k chip, as long as you don't exceed max voltage your only worry should be heat. Doing a delid and or investing in a AIO cooler will do wonders. Reading up past user experiences helps a whole lot too - chances are someone probably tried overclocking it before, like Vince stated.

You should also only OC in the motherboard, not using a software. The motherboard is a safer environment than a third party program, you will probably see your clocks behave very differently if you boot into it through the motherboard instead of applying it through the program.

Also that monitor resolution issue happens frequently for people with dual monitor setups. I'm not too sure why myself but I imagine GeForce Experience frequently uploads/stores presets when updating drivers, even if you don't press optimize.

TIL.

TIL you don't actually need a space between a number and the next symbol token. It somewhat makes sense since symbols can't start with numerals, I just never tried skipping the space entirely. There is also rarely a case other than macros when symbols can actually legitimately follow numbers without any operator in between.

I did some tests, and these all work amazingly:

PHP код:



#include <a_samp>


#define eXX

#define _XX

#define xXX

#define bXX


main()

{

    printf("",

        0eXX,

        0bXX,

        0xXX,

        0_XX);

}

More worryingly, guess the output:

PHP код:



#include <a_samp>


#define xFF


main()

{

    new a = 0xFF;

    printf("a = %d", a);

}

If pawn had octal this would be even more fun:

PHP код:



#include <a_samp>


#define xFF 255


main()

{

    new a = 0xFF;

    printf("a = %d", a);

}

But it doesn't...

OK... Do you have anything to say about the content itself? That would be far more useful TBH.

The content itself is helpful but the method of explanation needs like ages to be understood by the new people in scripting.. just like Eminem in RapGod song takes time to understand what's he saying for natives and other people..

PHP код:



#undef tabsize

#pragma tabsize 0

Hack right back at you! (tested)

What is "%00%0\10;%0" for?

PHP код:



#define tabsize _DUMMY_do_not_use_tabsize_0

works just as fine for me (Russian compiler)

No clue - you aren't really meant to redefine pragmas, so I think the compiler is getting confused, processing the word "tabsize" (hence advancing the pointer 7 characters), then doing the replacement, then thinking there's a new symbol starting from that point on.

Well obviously. But I doubt anyone with the knowledge to do that will be using "tabsize 0" in the first place.

Yes, but that will break ANY "tabsize" use, even good ones like "tabsize 4". The extra code checks that there is a "0" between the end of "tabsize" and the end of the line ("\10;"). So strictly speaking this will also ban "#pragma tabsize 10", but in many years I've never seen indentations other than 0, 1, 2, 3, 4, and 8 (and that's including all languages, not just pawn), so I think we're good.

Given that, you can also bypass it with:

PHP код:



#define ZERO 0

#pragma tabsize ZERO

Maybe not really learned as I knew about named parameters, but finally used for something useful:

pawn Код:

#include <a_samp>

main() {}

public OnGameModeInit() {
    new a, b, c;

    Test(.foo = a, .biz = c);
    printf("%d %d %d", a, b, c); // 15 0 45
}

Test(&foo = 0, &bar = 0, &biz = 2)
{
    foo = 15;
    bar = 25;
    biz = 45;
}

99% of the time you don't need floatsqroot. Yes, if you want the exact distance you need it, but most people just want to know if something is in range of something else. To check the range you do "if (distance < range)". However, getting the distance requires a square root. Instead, you can square the distance and square the range: "if (distance * distance < range * range)". Since a square root followed by a square is equivalent to nothing, this is the much faster: "if (partial_distance_calculation < range * range)".

TIL how tags work in pawn, mainly the float tag that is implemented with operator overloading. See float.inc.
