So... apparently Rust's "panic!" macro generates a ud2 instruction on x86-64 (literally an undefined/illegal instruction). It also generates a function called _ZN10sys_common6unwind12begin_unwind21h17424040669044986343E that it does not even call.

Hello, Anon. Sorry I cannot stay, but I have to be up in less than six hours.
And yeah, whoever is managing the creation of this language does indeed have a few screws loose. Try compiling a static library with it. Just one use of panic! makes it throw in everything plus the kitchen sink. And yes, that includes the networking libraries. Why? Because why the hell not?
I may just end up defining my own error function that will just print what I want and call exit().
>>52304885
I hate to defend Meme++ in any way, but whoever wrote that should just use a macro and it would make it look very clean.
>>52304889
Just use C then you fuck. Rust is like that for very specific reasons (which you should know since you're learning it)
>>52304899
I did, and as much as I'd like to I think I'd lose marks for it
It's for coursework
I'd do a neat version doing something like a fold or a map or something, but then it wouldn't have the same performance (even though it theoretically could)
>>52304926
>I think I'd lose marks for it
What? Why on earth would you lose marks for not making your code stupidly long?
/dpt/ what's the dumbest thing you've ever done while debugging, I'll go first with what I just fucking did.
I added a pause state for my game that, believe it or not, would pause the game when you pressed the Pause key.
Long story short, it worked fine, then suddenly after handling some other semi-unrelated code, my pause state wouldn't stick, it seemed to pause and then unpause straight away, like a stutter.
It only seemed to work when I held it down, but after releasing the game would look like time passed instead, like the game kept updating through the pausestate which was supposed to be impossible.
About 20 minutes later I release I was pressing the print screen key instead of the pause key.
Of all the fucking keys on the keyboard that could give a buggy looking pause state error, it would be that key.
Any one else have any stories? This was so dumb I had to share it, maybe someone else wants to share a similar experience?
>>52304540

A lot of C++ people and OO people and 'idiomatic code' people don't like macros
Module leader is a fan of idiomatic c++ OO code
Will check though
>>52304966
That's literally what it does though
Compilation can be faster (depends on the compiler) because anything outside of the function doesn't need to check the local symbols
Locality is obviously good for the same reason local variables are good
>>52304915
For very dumb reasons! A language designed on the principles of "you don't pay for what you don't use" should not add in so much junk to an executable that can be guaranteed to never be reached. And no language, under any circumstances, should generate an illegal instruction, especially as a way to terminate a user process. I can see some uses for the instruction in kernel level code as Linux uses it (Linux uses ud2 in inline assembly where there's a bug to completely shut down the kernel), but in userland code, it has no place.

So in C# in VS on a WPF Canvas, how do you detect collison between two rectangles?
I am trying to make a game of snake and I was able to detect collision on the border of the window, but I cannot figure out how to detect collision between my snake and a rectangle.
Anyone help me out?
>>52305102
why won't he write a vector class that isn't total shit then?
>>52304966
not him but all it does is read from file real quick and add it to the dependency list...unless the function is called hundreds of times and there are synchronization issues, the code will run fine.
I can't immediately come up with any bad habits one might pick up from this besides issues with buffers and perhaps making for dips in performance where performance is key, like in games.
>>52305103
>WPF Canvas,
> how do you detect collison between two rectangles?
Probably manually, since you're using a canvas, right?
Not that I know anything about WPF, but generally the "canvas" idea is just to give you, effectively, the direct ability to draw in an area, pixel-by-pixel.
Someone make a new thread quick, the trap boogeymen are gonna beat us!
>>52305137

We need a /prog/ board tbqh desu
>>52305210

we need a /phi/ board

(that includes programming)
>>52305148
Why are you using WPF for a game? You've got XNA, or even Unity which has built in collision detection.
>>52305103
by manually he means check for an intersection between x1, y1 and x2, y2.[0][0][0][0]
[0][0][1][1][0][0]
[0][0][1][1][0][0]
Here there are two rectangles a 4x3 and a 2x4 and they intersect at the points marked with [1].
To check this manually you would take a point at any of the corners and check if it shares an x and a y with the other rectangle.
if it shares an x it could just be below or above but if it shares both an x and a y it is over-lapping at some point. If you need to find the rectangle/square of intersection, you would just need to find all points that share x and y across the top most row and then repeat the process on any column rows that happen to also share a y, with special consideration to x values that were shown to be overlapping.
so you go across from the the point that shares an x and y and note the number of points across from that point
apply the same process over time and increase y at each time interval
>>52305223
I think they've made it so that philosophy falls under the humanities banner and that board exists after a tyrade on the science boards. lol.
>>52305148
>How would you do it in a regular window then?
I have no idea what you're asking. WPF is a framework for building business applications, not games.
> Also what do you mean by manually?
I mean you're using a canvas. It's roughly equivalent to working directly with video memory. You don't have any libraries to support what you're trying to do.
You should either use some babby gaming library or start reading books on advanced concepts like efficient collision detection.
>>52305271
errr the x1 y1 x2 y2 deal might be off, heh
I meant to infer that one of the corners belongs to an object 1 and the other corner belongs to object 2. Sorry if this was more confusing than helpful.

I don't think that works at all.
Also, X, Y, Right, Bottom are horrible names.
Either x1,y1,x2,y2, or a.x,a.y,b.x,b.y, or left, top, right, bottom, or left, top, width, height.
>>52305391

It's the built in rectangle of XNA.
>>52305309
Well, unfortunately for me, this assignment is due in 5 hours and we have to use WPF application in Visual studio to do it.
>>52305423
I considered doing that but I'm not sure if it would be optimised very well
If the performance is good (I don't need amazing performance, it's a simple project) I'll do that
>>52305394
It works and I think x, y, right and bottom work well for what the particular utility calls for. That is to say that a rectangle does not account for intersections, some kind of event handler would, and in handling events it specifically looks for a certain set of circumstances to occur. If it can be sure that only the right and bottom are necessary for placing the one rectangle in reference to the other's draw point then the handler need not be so "informed". What would it do with all that superfluous info? It'd be wasting space.
>>52305429
So it has X, Y, and Left, Top? WTF?
Anyway, make it readable. Be consistent.
>>52305461
The first line makes no sense.
If (rec.Bottom < other.Y)
which I assume is equivalent to (rec.Bottom < other.Top).
Maybe your coordinates are all fucky, but that logic is bad.
You're going to have to be doing comparisons to, for example, X + width. You can't test for collision by looking only at each X, Y, right, left.
>>52305394
And I'm pretty sure it does work senpai.
>>52305523
they clearly aren't colliding
the smaller one is clearly in front of the larger one
>>52305523
NOW TRY AND MAKE THE SMALL BOX BOUNCE OFF THE BIG BOX WITHOUT LOOKING UP HOW TO DO IT PROPERLY THEN POST CODE
>>52305518
Right is a property that calculates X + Width, you'e just embarrassing yourself.
>>52305518
Look at it for yourself.
Also, please note that drawing to screen implies that 0, 0 starts at the top left hand corner and not be the bottom left hand corner like on a cartesian grid.

don't forget to allow it to exit on close. Aside from that, I dont' really know what you're trying to do with it so I can't say much more beyond exit on close.
If it's a program for pracitcing using swing gui tools, why not make one that swaps out panels using the layered pane?
>>52305800
It's fairly unlikely that they'll be exactly equal, unless they have an offset that's a multiple of their step (i.e. if they move by 3 each time, be 3K apart)
>>52305785
Nothing is at the right place.
Even the NORTH, EAST thing I used does nothing since when I change the size of the window everything is just side by side.
>>52305775
Like I said I don't have any choice. And I like Java anyway.
>>52305821
Funny you say that since the left does moves by += 3 and -= 3. So if they aren't exact, how do I go about doing this?
>>52305812
Well I just have to reproduce exactly the picture I posted.
Here's what I have when I run it (I change the size of the window and didn't add al the buttons but it's already a mess).
>>52305800
It could be that maybe your snake takes steps that set it over the tile offset, it could be that your code implies that simply landing on a tile in the same column row would mean it has eaten even though it would have to land on the same point to do so...
Really, there's a lot of things it could be.

Hello guys, I have a short problem, i'm programming in Python and I'm using a forLoop but it don't works correctly, or maybe I'm doing wrong.
I have a list with True or False values, my loop is looking on the list and it has to tell me if the value is True or False, it's okay with "i" but "i-1" always tell me it's False, here is this part of the program :
for i in range(len(quadrillage)):
voisines = 0
if i!=0:
#To not read the last entry of the list
if quadrillage[i]:
voisines=voisines+1
Then i return voisines and it always return 0 instead of 1 if i-1 == True.

if it helps to use your hands, do it. For example:
the largest item goes in my left hand.
I pick up the first item in this arbitrary array. As it is, this item is the largest.
I check if the next item is larger than the item in my left hand. If it is then I drop the item in my left and using my right I put the new largest item in my left hand. Else I continue traversing through the array.
Now go back and replace left hand for a variable called largest and right hand for arr[i ].
Most sorting algorithms can be figured out using two hands in this way. You are over-complicating it for yourself. Fuck the rules. Just make money, smoke trees and don't worry about fucking bitches. .

i did it thanks brosvar nums = [56, 34, 67, 435, 74, 654, 45353, 38];
var largest = nums[0];
for (x = 0; x <= nums.length; x++) {
if (nums[x] >= largest) {
largest = nums[x];
}
}
console.log(largest)
I want to extract some loud and sudden noises from very long audio recordings. I don't want to do it manually because it would take too much time and because those noises aren't easy to find by just looking for them in Audacity.
Is there any Python framework that I could use to somehow analyze and manipulate the audio? Like OpenCV but for audio.

Just so you know, the radio buttons, textfield, label, combo box and enregister button are all on North. The text area is in center. The other two buttons are also in center.
I think so anyway.
Try not extending the JFrame class and instead just create a JFrame variable and modifying that to fit your needs. It does what you need it to do that way and then allows you to call the SwingUtilities.invokeLater() function to allow it to redraw correctly.
Where can I learn functional programming?
also why should I learn functional programming? I'm told I should, but not why?
>>52306227
C++, C#, Javascript
In a pinch I can do C, but it's not great quality code
>>52306441
cause then you can do things as you would explain them to another person, without the "need" for serious abstraction.
So, after you've implemented your functions you can simply say
Subtract( these two numbers )
Take the result of subtract( these two numbers ) and multiply( subtract( these two numbers ) by 7 )
calculateWeeks( multiply( subtract( num, num ), 7 ) )
It basically allows you to omit certain convolutions you'd find in procedural code by allowing to split the processes at points more in tune with natural language over the abstracted version presented by the "blank slate" of the memory map.
>>52306537
err...calculateWeeks is more informational.
It might look more like
calculateWeeks( num, num )
and then apply num, num as it was in the function declaration.

Reading raw PCM data isn't that hard. Use a library that will load a WAV file into memory, and you can just go through the samples.
libsndfile is one for C, so there is probably a python wrapper for it or some other library you can use.
You may want to do some sort of Fourier Transform on it though, because the amplitude at different frequencies will appear louder to humans. e.g, The same amplitude will sound a lot louder at 2KHz than it does at 20KHz.

Pie = frosting;
Okay now why the fuck do we set pie equal to frosting. Why not just use pie throughout the code? Explain to me /dpt/

Vector handles everything for you, you don't need to manually resize and copy. Primitive types are treated no different than Objects. Objects are just pointers after all.

Not sure what you're asking. Pie is global and can be used throughout the class and possibly outside it.

>>52308508
"Pie is Global"
Hello new t-shirt idea.
>>52308508
Lol. Well its for java oop apprently we have the uninitialized variable outside the constructors and then witin the constructor were setting it equal to another variable.
In short im asking why would you do this? Benefits?

That's called a setter and is used to control what changes variables. The alternative is a getter. Basically you create a class for others to use and so this helps you control how they use it. It could also be because your class is initialize by a user given variable and don't want to make the user pass it in to every function so they give it once and you save it within the class.
I want to integrate some kind of real time communication into my program, preferable I'd like peers to be able to detect each other locally through something like mDNS but also over the internet somehow, I'd like to avoid a server and have peers detect themselves through other means, maybe peers in a group share their peerlist or peers try to mutually find each other, I'm not sure yet, either way it wouldn't be conventional client/server, I'd like it to be decentralized or distributed so there's no need for the users to worry about the state of a server or addresses etc.
Does XMPP seem like something I should read up on and use for this, is there a better alternative or should I consider rolling my own methods and protocol for this kind of thing?
The intent is just to have something easier for the users in the end, I just want them to be able to connect to each other no matter what the circumstances (no reliance on servers, NAT problems, WAN connection, etc.).
>>52308508
Pie is not global, it has package visibility, but it won't be inherited.
>>52308448
This example doesn't make much sense, but it's useful in more complex classes. It allows you to maintain consistent state within your classes members, without having to remember to manually update related members. A classic example is a temperature class.public class Temperature {
private int celsius;
private int farenheit;
public setCelsius(int tempC) {
celsius = tempC;
farenheit = convertCToF(tempC);
}
public setFarenheit(int tempF) {
celsius = convertFToC(tempF);
farenheit = tempF;
}
}

Just realized I am an idiot, pls ignore.
That shit method is a constructor. When you create a new object in Java using new, you call a constructor of your class, which has the same name. This means that when you create a new object of type shit, you can customize the value of it's pie variable during creation time, rather than manually altering it later, which would be bad form. You can also have multiple constructors with different argument types, which are useful for objects you can initialize in different ways.
