It's like 0.9999... = 1.

Yes, you can prove it because 1/3 = 0.333..., 2/3 = 0.666..., and 1/3 + 2/3 = 0.999..., but there's something awfully disturbing about it.

Thankfully, we can just use fractions though, but then some arsehole discovered numbers that can't even be represented as fractions.

You being too thick to understand it doesn't mean there's anything "off".

That is all.

Irrational numbers are rational because after an infinite number of digits the pattern repeats.

>>52591497
> can I really just use void*? almost all of those functions need to know about the type
The only thing they need to know about the type is its size.

But beyond that, doing this sort of shit with macros is a fairly big clue that it's time to stop using the feature-limited trial version of C++ and use the real thing instead.

>>52591587

Meh. If you want to do game dev on a restrictive architecture, it's best to do it on an existing classical game console, which at least has some documentation floating around for how to do hard tasks. Or, since many of them were done in assembly anyways, can be disassembled.

Doing shit the C and SDL way though, is probably more satisfying.

makefoo(&f, bar);

>>52591382
Also to the anon that can't understand it. If there is an infinite anything to a number, it has defined a domain all to itself. A domain all to itself is called a realm and of a realm that is self-referential throughout is an identity, often cited as the number 1. This can also be regarded as a single dimension. Multiplying this number by itself creates a "squared" area and introduces the idea of a second dimension commencing beyond this numbers realm, which is essentially the start of the second dimension presented as 2 in a mostly abstract and unfettered sense.

So to be more clear, it does not equal 2, it represents 1 in a sequence that has reached the limits of its identity. So a 2. Maybe.

He once said that Haskel should be great for games, and garbage collection pauses should not be a problem since you can just call the GC on every frame. Like... GC events still have significant overhead. That shit wouldn't be feasible for any kind of AAA title. Not to mention all the other obvious reasons not to use haskell for games.

Went on about racket a lot and how powerful it is. But fuck all developers know it. It would be a 10x better at least just to use a language that developers know like C++, Java, C# or even JS for UI. Why make them learn and entirely new language with a different paradigm to what most people know just for a UI library? If VR really takes off, chances are Carmacs work here will be hardly ever used and people will just use some shitty open source UI lib written in python or some shit that everyone can figure out how to use in 2 minutes.

There's a reason most successful development platforms don't indulge in meme languages. They use what their target developers market knows.

Guys I have panel class with buttons, text fields and stuff.
Button has action listener which starts tetris game.
I'm working with java awt/swing. Is this possible to update tetris playground view which has to be printed in A class (buttons, textfields etc), when new threads is running in B class (playground, blocks, game stats etc).
How to do it right way?

>I never got used to lambda, they seem a little complex
Not at all m8, I'm fairly used to them myself. A lambda expression is just a function that describes how to do something. Reduce takes a function with 2 arguments and a list, executes the function on the first 2 items and with the result, repeats with the next item. So for factorial, if you use reduce and a function x*y on a list containing 1, 2, 3, 4, 5 (if num is 5), it will do

list is [1, 2, 3, 4, 5], use first 2 items for function
1 * 2 = 2
list is [3, 3, 4, 5] continue
2 * 3 = 6
list is [6, 4, 5] continue
6 * 4 = 24
list is [24, 5] continue
24 * 5 = 120
list is [120] only 1 result so finish and return it

Except I'm pretty sure it doesn't actually add the item to the beginning of the list, it just passes it to the function again, but it's done like this here to help illustrate

does every file have an EOF character?

 for (i = 0; (x[i] = getchar(fp)) != EOF; i++); 

this is throwing a segfault and i can't understand why input works as intended up to the end of the file, where it tries to go beyond and gets stuffed by the compiler.

sweet defs

>>52597790

fuck me. wouldn't that throw a different error though? the problem is the program trying to access protected memory and failing, not trying to stuff too much data into a char and failing.

>>52597720
EOF isnt a character, it is a special return value of getchar. Thus, there is no way to craft a file on which getchar wouldnt do the right thing.

As for your segfault, assuming x is a char [...], I think the assignment inside the parenthesis forcefully converts the return value of getchar from int to char, and then evaluates to the value it effectively assigned to x [i], which is not EOF anymore. Please try assigning to a temporary int variable in the for(), which you then assign to x[i] in the body.

>>52597807

or, maybe the EOF is getting truncated and thus not setting off the for loop's conditional? does that sound right?

>>52597807
assigning EOF to a char doesn't give an error, it just typecasts and probably truncates. it becomes != EOF at that point

>>52591285
Is there a way to write the output of

urandom(length) 

to a file and then later read that file to get the data back? The problem is that urandom can output non-printable characters as well. So encoding with Unicode is not a viable solution. I was thinking about encoding the output in hex or base64 for example, then store the data as such, then retrieve it and decode, to get the original data back but it is not working either. I'm pretty much running out of ideas. I'm using Python 2.7.

Unless you operating system is old as shit, it should probably support binary files. But right, they are architecture dependent and whatnot. Base64 is a very good solution, the only thing I can ask you is: in what way didn't it work?

The encoding part works (I tried encoding with base64) but when I try to decode it doesn't do anything. printing the variable returns the encoded base64 even tho I decoded it prior printing it. That's weird.

>>52597928

it's hardly a smile, it's more of a grimace. which actually pretty well encapsulates my reaction when you make accidental eye contact with a stranger

What gives? What should the decoding process produce, and how does that compare to what it actually produce? Show some code, since the basic idea is right, the problem probably lies in the implementation. What happens if you try

 base64 -d your_file 

, assuming that you are writing the encoded data into a file?

>>52598025
Basically the decoded data should be exactly identical to the encoded data. That's the hard part. Unless I'm being pretty retarded. Take a look:

data = raw_input('Enter data to be encrypted: ')
print('data:', data)

key = genkey(len(data))
print(key.encode("base64"), file = keyfile)

cipher = xor(data, key)
print(cipher.encode("base64"), file = cipherfile)
print('decrypted:', xor(cipher, key))

cipherfile.close()
keyfile.close()

# verify
cipherfile = open("Cipher.xor", "r")
x = cipherfile.read()

keyfile = open("Key.xor", "r")
y = keyfile.read()

x.decode("base64")
y.decode("base64")

print(x)
print(y)

The

genkey()

function simply uses urandom.
The Key.xor and Cipher.xor files are opened as write only earlier in the program, that's why I closed them before I open them as read only. (Yeah I know this part could be better implemented, but right now this isn't a priority). Finally, the xor() function XORs the data + randomly generated data together to created a Ciphertext that is then encoded to Base64 and put in a Cipher.xor file. Same thing for the key. Now, I need to retrieve both the Cipher and Key in order to decrypt them. To do so I simply read the files and retrieve the base64 output. Then I need to decode it (non-working part) so I can throw the result to the XOR function to decrypt the data.

In VHDL you don't just clamp things together and it just werks™, you have to actually understand the details.
The actual processor parts are all piss easy, anyone can XOR some bits.
The tricky part is hooking everything up, watching for overflow flags, making sure temp registers are the right size depending on the operation.

Nothing is implied, all casts are explicit. Please tell me more about how modifying a keymapper in a highlevel language is so difficult.
