I think any compiler would be smart enough to know that it only aliases what you casted from.int fill(int *restrict x, float *restrict y) {
*x = 1;
*y = 0.5;
return *(char *) x;
}
The char * couldn't possibly alias y.
>>54750848
it's different when you use restrict, otherwise it's not allowed to assume that it doesn't alias anything besides what you casted from

the rule as mandated by the C standard is that char* can alias any object. therefore it is not valid in the code example to simply return the first byte of the int since the char* might alias the float*

The whole point of the discussion is that the char* doesn't even matter! By the time the dereference through the char* is made, *x and *y were already accessed and those accesses can be reordered because x and y can't alias! That's where the undefined behavior is!

I think what I'm doing wrong is that when a new player joins, I create a new Player object. In his game, he creates an "enemy" object instead. Would it make sense to have a separate class that looks and acts almost exactly like a player, except it's not called a player?
>>54753536
What I think should be happening is that as soon as there's a second player in the server / connection, a new player object should be created and rendered. If that doesn't happen either the second player isn't being created or there's an issue in rendering / network code

I feel enlightened. I understand why Π-types are functions and why Σ types are pairs.
>>54757484
explain?
>>54757484
>why Σ types are pairs
no. Î -types are functions, hence pair is a special case.
Is it autistic to use unicode greek symbols as variable names?
>>54757558
The type represents the number of objects of that type. For instance it is possible to have the unit type denoted as "1" (the unit being the single object of the type), the boolean type denoted as "2" (true and false), and the bottom type denoted as "0" (no objects, meaning no proofs).
This makes a lot of sense when we do things like represent the non-dependent pair as multiplication (A x B) and dispoint union as addition (A + B).
We can really understand why A x B is multiplication by organizing all of the elements of A x B into a grid and shown to the left (1000 hours in ms paint).color coding:
a1, a2, ... : A
b1, b2, ... : B
(a1,b1), (a2,b1), .. : A x B
Thus it's pretty clear that the total number of elements is equal to elements in A times elements in B.

>>54757797
Lemme finish.
Product means pair. Sigma means dependent pair.
>>54757761
Now to understand why on earth Σ (repeated addition) represents a pair, even though pair is usually product, see the next drawing.
Since the type of the second element of the pair B(a) depends on the first element of the pair a, that means that the number of objects in that type B(a) also depends on the object a. So therefore instead of an easy rectangle like we had in the previous post, we have a series of rows (for each a in A), with a variable number of collumns (variable, dependent on a). Thus the number of elements in the dependent pair can be found by summing all of the collumns in the rows.

if we see generic type list as a function from a type to another type
list (x) = 1 + x * list (x)
ie list is empty (1) or (+) a head and a tail (x * list x)
so
list(x)-x*list(x)=1
so
list(x)=1/(1-x)
so
list(x)=1+x+x^2+x^3...
so
a list is
an empty list(1) or (+) a list of size 1 (x) or a list of size 2 (x^2)...
if we differentiate
list(x)=1+x*list(x)
list'(x)=x'*list(x)+x*list'(x)
list'(x)=list(x)+x*list'(x)

Dependent types are first class objects, and objects are first class types.
>>54757986
Wow, differentiating dependent types. That's really rad.
>>54758007
https://en.wikipedia.org/wiki/Dependent_type#Dependent_pair_type
Also, if you think about it mathematically, summing a constant = multiplication, therefor sigma is a product, when the summed elements are not dependent.
e.g. Σ (n=1 → 5) 3 = 3 + 3 + 3 + 3 + 3 = 3(5) = 15
>>54757901
>>54757920
So time to talk about functions. Starting with non dependent functions first, we all learned from algebra in highschool that you can draw a function like a line on a graph. This is of course because every x value corresponds to a y value from the equation y = f(x).
Now in type theory let's stick to distinct objects rather than a continuous line. Our function f : A → B maps objects a : A to other objects b : B. Every a maps to some b.
Thus we can draw this out as a grid, with the rows denoting inputs a1, a2, ... and the collumns denoting possible outputs b1, b2, ...
The filled in squares represent the output of the function, in this case f is orange and g is green.
f(a1) = b1
g(a1) = b3
f(a2) = b2
g(a2) = b3
etc.
Now remember earlier that the type represents the number of objects in the type. So using probability we can determine that there are B^A combinations of functions of type A → B
>>54758245
Dependent typing is a specific kind of first class typing, from what i've seen
>>54758245
Now understanding dependent functions as Π(repeated multiplication, a less common operator than Σ), we do the same thing as with Σ-type. Instead of an obvious rectangle, we have rows with variable number of collumns. The number of possible functions (h) of this type can be found by multiplying the length of each row.
>>54757761
>Everything is a special case of the dependent function but that's not the point.
Only if you've got an impredicative theory. Try Church-encoding sigma in CIC, for example.
>>54758261
Not really. First-class types make me think of reflection, whereas dependent types are where the type checker can use values as types. So they're orthogonal. If your universe type has an eliminator, you've got reflection, and therefore both.

Dependent product ~ Cartesian power (function)
Dependent sum ~ Cartesian product (pair)
Cartesian sum (union) doesn't have a dependent analogue, but can be easily encoded using a dependent sum. In the same way, a Cartesian product can be easily encoded using a dependent product. A dependent sum can only be encoded as a dependent product if you have impredicativity.

OOP as a whole is pretty much useless. If it's the only way (in your language) to get certain features, like encapsulation or dynamic dispatch, then yeah, you're kind of stuck with it.
>>54758870
starting with something like C++ you'll just feel like it takes so much shit to do anything and end up being demotivated to keep going, start with something simple and when you feel comfortable with the basics move on to some other language
why can't I read from a .csv file with a while (in.hasNextLine()) on java?
from my point of view it should work, and the .csv is pretty simple and clean, so I don't know
this should be a list of country and population, like
Taiwan,25 155 655
so I triedFile inputFile = new File("paises.csv");
Scanner in = new Scanner(inputFile);
while (in.hasNextLine()) {
String[] line = in.nextLine().split(",");
System.out.println(line);
}
but it's like the while doesn't work, if I put a system.out just to check if it got there, nothing happens, as if there was not next line
>>54759229
what does the debugger say about hasNextLine()?
>>54759029
kek
>>54759267
what do you mean? it actually compiles and runs without a problem, I'm on blueJ and the debugger shows nothing, which is worse I guess
the problem is something related to dealing with a .csv, if I make a txt with just names in each line it reads fine, but a .csv with names and numbers separated by commas messes it up for some reason
I needed to read each line and test to save the bigger population on a variable, then the smaller, and that was the only way I thought about it

Or at least probably won't be by C++17:
Trigraphs were proposed for deprecation in C++0x, which was released as C++11.[5] This was opposed by IBM, speaking on behalf of itself and other users of C++,[6] and as a result trigraphs were retained in C++0x. Trigraphs were then proposed again for removal (not only deprecation) in C++17.[7] This passed a committee vote, and trigraphs are expected to be removed from C++17 despite the opposition from IBM and others.[8] Existing code that uses trigraphs can be supported by translating from the source files (parsing trigraphs) to the basic source character set that does not include trigraphs.[7]

>We graduate two times more Americans with STEM degrees each year than find STEM jobs, yet as much as two-thirds of entry-level hiring for IT jobs is accomplished through the H-1B program. More than half of H-1B visas are issued for the program's lowest allowable wage level, and more than eighty percent for its bottom two.
>Raising the prevailing wage paid to H-1Bs will force companies to give these coveted entry-level jobs to the existing domestic pool of unemployed native and immigrant workers in the U.S., instead of flying in cheaper workers from overseas. This will improve the number of black, Hispanic and female workers in Silicon Valley who have been passed over in favor of the H-1B program.

if icc is correct why don't you tell the gcc people to change it back to how it was
>>54759403
Your code is okay. Something else must be wrong. Maybe the file can't be opened. Maybe the file can't be read. Maybe the file can't be found. Java 8 requires throws FileNotFoundException surrounding the Scanner(File) constructor. Maybe you accidentally dismiss the exception.
I recreated your code 1:1 on my computer and it works. No memes.

I don't think the video did a very good job at explaining it. Does anyone here think they could make some sense of the code?

The server code is in another .exe, it returns a number (the "type" variable) depending on the action it needs to take (a person connects, player moves, etc.)
Line 63 is what really confuses me. It gets called every single frame. He's adding a new object every single tick.
>>54759782
>change it back to how it was
do you understand the concept of undefined behavior?
hey /dpt/, is this a good idea or a waste of time?
I'm thinking of taking of just taking a huge bunch of coding problems and solving them, then writing them out in every language I want to market myself as knowing, and finally including a bash script that runs all the other programs on the spot.
Good idea, or worthless?
>the aliasing argument is still ongoing
Holy shit.
what would you do?
If your favorite language has a code of conduct in its official website, it's shit tier

do projects with different languages
>>54759839
>Line 63 is what really confuses me. It gets called every single frame. He's adding a new object every single tick.
Have you confirmed it's actually doing that or is that what you think it's doing? If I'm reading it right, it will only create the new object if the ID doesn't exist already.
BTW that code is shit and needs to be refactored. At the very least you should have a function to get the object using its ID.

how is it undefined behavior and if it's undefined behavior what's stopping gcc from outputting the same as icc with -fstrict-aliasing like older versions of gcc

Unfortunately, the """argument""" goes like this:int add(int x, int y)
{
return x + y;
}>add(INT_MAX, 1) is undefined behavior
>no, it's 0, these 3 compilers generate x86 code that agrees with me!

>if it's undefined behavior what's stopping gcc
These """programmers""" don't understand the concept of undefined behavior but are eager to talk about it.
>>54760156

Working on a new personal startpage

>>54759839
Also, that if on line 56if (gameObjects[i]->getID() == ID){
int x = gameObjects[i]->Position()->X();
int y = gameObjects[i]->Position()->Y();
sscanf(data, "1, %d %d %d \n", &ID, &x, &y);
break;
}
Is that supposed to move the object to the position in the message? Because x and y are just local variables there. Did you mean to use references?
>>54760171
it's not undefined behavior, it's perfectly valid for char* to alias any object pointer

the way they currently compile the first function in >>54753222 is less efficient than the second function, and it's probably because of how the standard is written

>>54760119
Yeah, you're right, only 1 item is getting added, my mistake.
Another thing is that I can't get it to update the player that's connected from the internet. Both players can move on their own copies of the game, but only the one that was originally made on that copy is shown as moving, the other stays still. I'm not sure where it is that he's getting the new x/y position, I'm pretty sure it's at line 59, but when I set the GameObject's position to those values, it doesn't move.
And I apologize if you can't understand what I'm saying. My brain is totally fried right now so I'm having trouble putting my thoughts into words.
