Changed by Boggle bot to use a generator instead of storing discovered words in a list and then entering them.
I have an assignment to implement drop-out into a neural network that the teacher made. He wants drop-out to be implemented as a class, but the idea to me seems like it would be much better to use a function?
e.g. a function that takes as arguments the matrix of entries of the hidden layer and the probability that an entry is reduced to zero.
but the specification calls for a class in particular.
Should I just make it a class with a single method that works like a function?
I've seen very succinct examples of drop-out but he wants a drop-out that applies a 20% drop-out to the initial input and 50% drop-out to all the hidden layers so I can't use those ultra-succinct ones.
I probably sound like a retard but I have never used python before a couple of weeks ago and aside from that only done small assignments in R and java.
I don't really understand "self" and am much more happy with how in java you declare whether things are ints or arrays or what have you.

I'm learning Python, and I just recently started getting into classes. One thing that perplexes me is why would you have to write out each variable when you're assigning them to the class.class Point3D(object):
def __init__(self, x, y, z):
self.x = x
self.y = y
self.z = z
Anyone with decent Python knowledge, is there a way to iterate through x, y, and z without having to type it out like that every single time you create a class? Of course, assuming that self.x = x, self.y = y, etc.

So that site doesn't have a web service, so you can't use the soap generator.
What you CAN do, is autogenerate classes based on a copy/paste of the XML.
For example, open the first XML example. Copy the XML.
In visual studio, create a new class and put your cursor where you want this class to go.
EDIT -> Paste Special -> Paste XML as Classes.
If all goes well, you should end up with multiple classes like pic related.

Working on the foundation for my rhythm game server.
There are three entities: server, group and game. They are stored in a tree structure. On top the server. Below that, groups. The leaves are players.

>>51650970
Actually, now that I'm thinking about it, I'm still confused as to why I'm supposed to AND 80000000 (or in my case XOR).
My sign bit is F for a negative number, 0 for a non-negative (input is 4 decimal digits, and the output never exceeds 8 decimal digits). So wouldn't I want to XOR F0000000 (or FFFFFFFF since another anon suggested -1) instead of 80000000? If so, how would this work since the overflow bit (result of XOR for my CPU) would only be 0 if XOR'd against something exactly F0000000 (or FFFFFFFF)

I don't know what you mean by sample of the code. If you mean the code for the computer, it's been compiled for us since I guess he didn't want us looking at it.
Is it possible to learn a decent amount of programming by looking through existing codes/programs while occasionally looking up certain features of them?
>>51651175
Why not read a book?
>>51651167
I'm talking about the code you're writing.
Are you this dense, in real life ?
got a super easy project idea but its something to do
one of those mind map programs
like you place circles and rectangles
and can have arrows going to and fro
and you can put text on the arrows and shapes
i could probably do it in a day or two if i have enough time
my other option is allocating shrimps
>>51651175
if you're starting from nothing, no
if you have already read a book, yes
>>51651183
>>51651192
Interesting.
>>51651192
I suggest allocating the shrimp.
>>51651162
Yes, I am. I got the .sm parser working in C++, but I wanted to learn Go. So I decided to start working on a client server based rhythm game.
>>51650962
I think he's saying that even if you wanted to purposely make something bad you should use c
>>51651345
Don't speak for me, rude prick.
If I read a programming book will I understand it? I'm worried that I won't. I'm worried that I'll read one and it'll hit me that I can't learn to program like I've always wanted and I think that scares me off from starting one. I even have a few downloaded. I'm 10% or more done with several courses on Codecademy. I don't know what the fuck my problem is.
>>51651184INP opsys
MUL en
STA xn
LDA x0
ADD x1
ADD x2
ADD x3
STA x
Note: This isn't actually what the code looks like, I'm just condensing it so I'm not posting 500 lines of garbage. I'm taking inputs for each digit, x3x2x1x0 of a number (xn is one number), where n is that digit, then multiplying that input by an exponent (10^n).
After that, I add all the calculated inputs together so x = sum(xn*10^n) for n <= 3 and that gives me my number x. If the user wants a negative number (that's a separate input for which I do:)INP opsys
XOR csub
BZE negnumber
Where csub = I 45 (Integer 45, the ASCII value for a dash, or the negative symbol) and BZE branches to the method that calculates a negative number that looks like:LDA c0
SUB x
STA x
c0 is just the number 0 and from looking in the memory, I do get my intended result stored in x, which is F followed by any 7 bits (a negative number).
My question is, how would I tell if a number is negative? (for example if the user inputs a positive number but subtracts a larger positive number) My original idea was >>51650801 since I thought F......./10000000 = F (where . can be any number but I obviously didn't use that in my code, this is just for representation, since decimals get truncated) but as it turned out, it interpreted FFFFFFFF as -1 instead of the hex number FFFFFFFF.

Better to find that out now instead of wasting more time on it, then. Also, don't be a little bitch and never open a book because if so you're guaranteeing you won't get better.

>Wow, anon. Impressive.
No, no. I am NOT bragging. The opposite. I was listing that as something similar to not starting a book. I couldn't even finish a course. I never even necessarily got stuck. Just slowly stopped doing it. When I'd go back it felt like I forgot most of it, but even then it's not like I wasn't able to progress at all if I tried hard enough.
I guess I just want motivation advice, except from people who actually program instead of someone in general.
>>51651422

>>51651363

Im making a board game (go,reversi,checkers,etc. ). Can one instance of an object be placed more than one arrays/lists/datastructures?
Because i want to track the number of tokens a player has with each player having their own tokencollection<Token> while letting the board administer its own array of tokens. So if on cell [0,2] there is a token by player one, that token should also appear in player 1's tokencollection<>.
Or is it bad OOP pattern design to let each player have their tokencollection? Its relatively easy to track them in the board array anway. I can also just give each Token an "owner" membervariable.
Is this redundant what im trying to do with this extra tokencollection<> per player?
its c# by the way
>>51651470
Ah, that's one I've got downloaded. I'll do that then.
>>51651670
>Can one instance of an object be placed more than one arrays/lists/datastructures?
Yes. You'd have to store the reference in the list, not the value.
>>51651670
>Can one instance of an object be placed more than one arrays/lists/datastructures?
Yes, after all you're storing references to the instance, not the instance itself.
Why not add an owner variable to the token object and have the board manage all of them?
Also, is it server-client based or just client based?
>>51649493

This is probably better, due to stuff like in Checkers when you reach the end.

Count the number of each character in a file. C'mon senpai I've had much worse I've figured out.

Read in a file.
Look at each character. For each character, add a 'point' to that character's index in the array.

I'm no C# wizard, but I can give you a Java example. I'm sure it's basically the same.Token blackGuy = new Token();
List<Token> t1 = new ArrayList<>();
List<Token> t2 = new ArrayList<>();
t1.add(blackGuy);
t2.add(blackGuy);
>>51651983
why so many though? why 256? how do i know where to put abc...z etc compared to ctrl-a or whatever?
>>51652056
>How do you store such reference in a list? How do you refer to an instance in c#?
For example, when you pass an object to a method, you're usually passing the value of the object.
Say you have a list full of dicks.
Here's some example methods:public void Ayy(List<dicks> dickslist)
{
dickslist = null;
}
public void Lmao(ref List<dicks> dickslist)
{
dickslist = null;
}
public void Tits(List<dicks> dickslist)
{
dickslist.Sort();
}
If you pass your list of dicks to Ayy(), and then check the value of that object after the method is done, you'll find the object you passed did not change.
If you pass your list of dicks to Lmao(), you'll find that your dicks are now gone, as the object has been modified by passing it in with 'ref'.
If you pass your list of dicks to Tits(), then the dicks will be sorted, as you're performing the action on the variable that is referring to the object.

Because that's how many different byte values there are. 8 bits in a byte 2^8 = 256 combinations.

In C, you can just use character literals, e.g. 'A' is just another way of writing 65. Languages where characters are a distinct type typically have ord() and chr() functions for converting between integers and characters.
It's easier to "prototype" designs in Mathematica, so I'm writing something that converts mathematica output to another language for opengl purposes.

"""word is the singular form.

I haven't owned either ever but I think that cats take equal amount of time when they're still kittens and they'll also take a lot of money (you still need toys, something for the cat to scratch and claw, food and stuff). The dog being dirty probably depends on where you live (but you'd still need to wash either regularly) and cats provide nothing of value either, arguably, they're more useless than dogs because a cat's life resolves around "I sleep and you feed me".

>>51652653
True. Then again, this isn't supposed to be any serious program, it's just the answer to a puzzle. lel
Trying to use an unused IO port as a software interrupt on an AVR controller in C. The ISR is justISR(PCINT0_vect) {
(*isr[PORTE])();
}
with 'isr' being a function pointer table. The generated code is shit. Because the function is indeterminate at compile time it saves ALL the registers. Is there a gcc function attribute to make a function NOT save any registers (save status register maybe) and make a function respect all its registers, even the ones the convention says it will disrespect?
Or should I just write all my interrupts in asm (defeating the point of using C in the first place).
>>51653045
Well, then don't ask other people to read your spaghetti code if you don't take readability seriously.
I'm working on something in VB (Yeah I know, don't bother telling me, I'm very well aware)
Right now I'm stuck on arrays, I want to push a button and have an array be created with the name of a string with any number of other strings stored in it, and then be able to select another string, create another array with any number of other strings contained in it, etc.
I've looked everywhere and tried my hardest but I have no idea, I guess I could create an array which stores the first string and all the other strings after it, and when I want to find a certain array just call on the first string, but then I won't be able to make another one because that array will have already been called.
Any ideas?
>>51653145
Sounds like you just want a two dimensional array
>>51653145
I realise I explained that poorly
Here's an image.
I want to be able to store the association between the single selected string on the left to any number of strings on the right. Then be able to click another on the left, and associate another set from the right.
>>51653214
Do I? How would I make it work with the concept I just described?
Where can I learn how to make good looking GUIs and how to select good colors for my GUI elements which go well together?
>>51653092
I do take it seriously; in fact, I adjusted my coding style to match the kernel's (to some extent). It used to be way worse.
>>51653269
Think of it as an array of arrays. You add an array ("Required", "foo", "bar") to the array. Then you add an array ("I am", "a fucking.bsa", "retard.esp", "send help.bsa"). Now you have
(("Required", "foo", "bar"), ("I am", "a fucking.bsa", "retard.esp", "send help.bsa")). The right box is the first element of each array inside the 2d array, the left box is the 2nd-nth element(s) of the array you select on the right.
>>51653324

Copy the design of another application. Everything has been done before, so there's no need to reinvent the wheel.
>and how to select good colors for my GUI elements which go well together?
Pick a color from the color wheel. This is your primary color. Pick the color directly opposite of the color wheel. This is your secondary color used for accents. If you need another secondary color. Pick a color between the primary and secondary color.
>>51653345
Ah, so a 2D array is exactly as it sounds, it allows you to apply values in a literal 2D fashion. I guess I'll have to create a class with properties and then create an array on load, then when I press the button add the stuff to the created array. Makes sense I hope.
Thanks.

Seems far more convoluted than the simpler option of a 2D array.

with a complementary scheme, that literally describes every single other color
>>51653449

Yes but if you ever want to swap the elements, change their order on the list and such, you will have to swap array elements around, with maps (dictionaries) it will Just Work (tm) since you're doing a basic key lookup.
