>>52198528
you can thank the T part of LGBT.

they've been legitimately holding back the LGB community for over 30 years and now they're shitting on crossdressers who simply do it as a fetish

the worst part is they're not even related to LGB
LGB represents sexual orientations between consenting adults
Transexualism is a mental disorder.

i'll stop off topicing now

>>52198567
crossdressing is just dressing/clothes
transvestitism is manner of speech and other shit
transexuality is wanting to be the other sex
transgenderism is thinking you are the other sex

>>52198567
they mean the same thing, a person who dresses as the opposite sex for sexual pleasure (usually)

Life was considered to arise spontaneously, the earth was considered to be flat. Just because homosexuality was once considered a mental disorder does not make it so.

>>52198783
>due to the sheer amount of information it instantly spits at you
There's only a lot of information spilled at you because the project is massive, not because it is verbose. If it were written in F# or ocaml there would be 5-10 times less code, and it would be more readable.

Why would python be harder to read? Python would also be 5-10 times less code.

>>52198764
If your function returns bool, no need for this, conversion will be done automatically.
In case it's C, there's no bool anyway.
In case it's any other language with this syntax, it's shit anyway.

>>52198787
>returns true if condition is something else than true or false
You should throw exception

    for i in range(100):
        if i%3 == 0:

        if i%5 == 0:

>C# is not as verbose
how so

>>52198848
In C99, true and false are macros defined as 1 and 0. The _Bool type and it's alias, bool, don't add anything.

>>52198900
Because C# has operator overloading, LINQ and unsigned integers.

what

>>52198931
>The _Bool type and it's alias, bool, don't add anything.
Yes they do, idiot. Any non-zero value assigned to a _Bool will be changed to 1, and zero assigned to a bool will stay zero.

#include <stdbool.h>
#include <stdio.h>

int main()
{
    printf("%d\n", 10);
    printf("%d\n", (bool)10);
}

>>52198848
>C99

Have fun trying to target MSVC.

>>52198848
nobody uses the _bool type because it restricts your code to C11-compatible compilers and adds literally nothing of value.

>>52198900
Properties

lots of little syntactical sugar things, like ??, ?. You can also put multiple classes in a single file, which often helps a lot.

>more features means less verbosity

>>52198958
>Transsexual women have physically female brains
so they're as mentally weak as women
so they're mentally ill men

>>52198986
hey guess what.
C has been using boolean logic for fucking ever
while(1) is the same as while(true)
all non-zero values evaluate to true and zero evaluates to false in all cases.
hell, you can even use the negation operator to treat a number like a boolean expression

>>52198996
_Bool is C99, not C11. Also, what the hell kind of shitty compiler are you using that isn't GCC or Clang?
>adds literally nothing of value
Sure, C11 isn't a big step up from C99, but it adds a few nice features (static_assert, _Generic, atomic types, multithreading etc.)

>>52198992
They apparently support C99 now.

>>52198951
>LINQ a language feature
>not a library feature

C# is deprecated by F#

>>52199040
does gcc even support threads.h?

>>52198986
The only thing this gives, is that foo == true works always, but no one compares logical values to true/false anyway, since it's not needed in C (and in many C-like languages).

>>52198986

I WOULD be impressed by bool if it only took up one bit of space, but it takes up 8 bits. Seriously, what the fuck is the point. Most people just pass 8 bools in a char as a bitmask.

>>52198205
It's literally one tranny who thinks that if he shitposts constantly then his degenerate lifestyle will become "normal".

>>52198998
>You can also put multiple classes in a single file
Wait, you can't do that in Java?

>>52198992
msvc 2013 have all the relevant C99 features now (variable declarations anywhere, compound literals, designated initializes, and yes, _Bool)

>>52199032
Yes I fucking know, but comparing any bool to 'true' directly isn't a logic error now.

>>52199054
GCC doesn't need to support it, it's glibc's problem. I saw some patches for it on their mailing list a little while ago, but it's not in yet.

>>52199065
Very few architectures are bit-addressable, so you can't have a 1-bit type.

>>52199065
smallest addressable block of memory is 1 byte
any block of memory smaller than 8 bits is being rewritten completely at the byte level every time you modify it, much like how the block size of an SSD is 512bytes and any modification means it needs to copy it to a new sector and delete the old one.

>>52199074
you can nest as many classes as you want to, if that's what he means

>>52199065
>Most people just pass 8 bools in a char as a bitmask

Wouldn't that be LESS efficient since CPU operations are optimized for the word size?

>>52199074
nope. And if i recall the class file name must match the class name.

>>52199138
>>52199074
You can. The file name must match the class name only if you declare the class as public.

>>52199112
>Very few architectures are bit-addressable, so you can't have a 1-bit type.
They could have made bool a[n] a bit array though. As it stands it's a completely useless addition to the language (especially since true/false require a fucking header)

>>52199162

Special cases are stupid.
>As it stands it's a completely useless addition to the language
'bool' is a lot more self-documenting that using int or something. All of the shit like size_t, ptrdiff_t, (u)intN_t, etc, aren't strictly necessary either.

>>52199182
>Java is shit

>>52198358
>implementation is just details

>>52199186
I'm suggesting that you don't even need bitwise operations if your bool is a word size.

>>52199213
>Special cases are stupid.
So just use ints for everything, oh wait...
>All of the shit like size_t, ptrdiff_t,
Those are necessary actually.
They needed distinguished types for them because the total number of addressable objects might different from integer or even pointer sizes.

    Sweetiebelle made remainder of Scootaloo and three.
    Applebloom made remainder of Scootaloo and five.
    Did you know that Fluttershy is right?
    When Sweetiebelle was equal to zero:
      I quickly said "fizz".

Ok, thank you.

In C#, how do I go about defining a root class or interface, set some property accessors, and have classes that inherit form it get those property accessors without having to define them in every class?

I.E. Root class has

string Name { get; set; }

And I have three class that inherit from that.
I don't want to have to write that line of code in those three classes, I just want them to read that it exists in the root class and inherit that property into themselves.

>>52199811
well in a sense, you're not subtracting the negative number meme, you are subtracting the inverse of a number modulo 5. A number raised to 4 will be 1 modulo 5, but the negation inverses it to be 4 modulo 5

It would unnecessarily slow on a 16 bit processor which would have to synthesize 64 bit arithmetic every time it used those functions, even though they never need those extra 48 bits.
That's why a typedef was motivated, so it could be the perfect size.

Subtraction isn't a meme.

You can apply subtraction to real life.

If you have 3 apples you can take away 2 apples to be left with 1.

Negative numbers are a meme though.

If you have 3 apples you can't take away 4 apples, it's just madness.

That's not subtraction you idiot, that's adding a negative amount.

>>52199934
feelio when you thanked me but I'm actually wrong

you are not subtracting a negative number, the negation happens before the modulo

you are subtracting an inversed modulo operator:
1 modulo 5 becomes 4 modulo 5, 2 modulo 5 becomes 3 modulo 5, etc

To break it down

8--i**4%5
8-((-(i**4))%5)
8-((-(last digit 5 if i is multiple of 5, 1 or 6 otherwise))%5)
8-((-above)%5)
8-(0 if multiple of 5, 4 otherwise)
8 or 4

1 or 6 module 5 is 1
-1 or -6 modulo 5 is 4

This is partly homework related question, I'm doing (what I think is more). Since I'm an ESL pleb please excuse my poor wording.

I was supposed to explain why the following code doesn't work and how to fix it.

abstract class Sequence[+A] {
  def append(x: Sequence[A]): Sequence[A]
}

It doesn't work because A is used in contravariant position (Function1 trait dictates that arguments are to be contravariant) so you can fix that by adding a type bound to append like

def append[B >: A](x: Sequence[B]):Sequence[B]

My question is as follows: do I know anything about B's variance? Would saying that B is contravariant to A make sense or saying that one type is co/contra/invariant to other type doesn't make sense in general?

>>52200108
>You can't have a negative number of atoms.
You can't have a positive number of them either.

Numbers are just convenient abstractions, what one mean by "I have have two apples" is a fuzzy notion of a set of things with some statistical distribution of atoms which could be considered "two distinct apples" - is an incredibly complicated concept, and practically impossible to precisely pin down, but that's why "two" is a convenient model for it.
And since it's just an abstraction there's no problem with saying "I have negative two apples", because you can take it to mean "I owe someone two apples".

Thanks

>>52200199
To help break it down even further

First, you apply the power operator **. The last digit will either be 5 if it's a multiple of 5, or 1 or 6 otherwise. Modulo 5, you get 0 if i is a multiple of 5 and 1 otherwise

Second, you negate it, you get 0 modulo 5 still if i is a multiple of 5, and this time you get 4 modulo 5 by negating 1 modulo 5, as -1 (for example) modulo 5 is 4

Third, 8 subtracting the result is 4 if i is not a multiple of 5 (so the end of the slice hits the end of Fizz) and 8 if i is a multiple of 5 (so the end of the slice hits the end of Buzz)

Probably by masking with 0xff, 0xff00 and 0xff0000.

in a way, negative numbers are just the shadows that positive numbers cast on the other side of 0, so negative numbers being real is the same as shadows being real, but shadows are just the absence of light, just as negative numbers are just the absence of positive numbers

my greatest achievement is one star on an old repo by some student with a chinese name, near the start of the school year

shit was so cash, thinking that guy looked through my code and maybe helped him

ECS is typically more attuned to procedural or functional styles. The only place where OOP is still sort of relevant to game programming IMO/E is for implementing different, swappable back ends like D3D/OGL.
I don't really know where it would be useful other than games, frankly.

Personally, I don't have a problem with the concept of OOP. I just don't find it useful enough to be worth the meme about how amazing and fundamental it is; there are plenty of other ways to do things like polymorphism and encapsulation.

yes, of course i know that, but what i'm saying is that "negative" doesn't really exist, it's just an helpful convention

putting - in front of a 3, when you're representing a debt for instance, is the same as writing "i owe" in front of the 3. by your retarded logic, there's an entire subset of numbers called the "i owe" numbers, which are counterparts to the natural numbers

>>52200968
>just means that you owe a POSITIVE amount of money to someone
>double negative is positive
that's how it works you innumerate camel fucker

>>52201004
Yeah. Ultimately if it helps someone or they find it cool that's all that matters. I'm not good enough at anything to produce something that people might use on a mass scale though so all I can hope for is tiny things.

>>52201055
we could also do the same with negative numbers and say that positive number are just negative ones with a minus sign.

>>52201055
charge of -x + charge of +x is 0
Negative charge is literally a thing

>>52201084
your point being?... how does that relate to negative numbers not existing you fuck

>>52201151
and again, the point being? at the end of the day, "negative x" is just a convention to avoid having to write "positive, but different, x"

Anyone else want to suck a trap's feminine dick and see him get embarrassed?

the reason homosex was removed from DSM in the 60s was because faggots were literally crashing psych conferences are running around half-naked and screaming.

> fun fact: this was called "zapping" in the anal-pumper community

they basically promised to keep doing this indefinitely until their classification as mentally abnormal was removed.

since psychologists are pretty lazy and since science overall has continuously diminished integrity, they went along with it.

oh boy you're going to love the complex number meme

fixed:

def fizzbuzz():
    for i in range(1,101):
        x=''
        if i%3 == 0:
            x+="fizz"
        if i%5 == 0:
            x+="buzz"
        if i%5 and i%3:
            x=i
        print(x)
