When doing boardDl, sometimes images or threads will fail to download, so at the end of the program, it will give you a script you can copy to re-download them. If you keep doing that and one thread just doesn't download, check if it was deleted.

>In computer programming, a function may be considered a pure function if both of the following statements about the function hold:
>* The function always evaluates the same result value given the same argument value(s). The function result value cannot depend on any hidden information or state that may change while program execution proceeds or between different executions of the program, nor can it depend on any external input from I/O devices (usually—see below).
>* Evaluation of the result does not cause any semantically observable side effect or output, such as mutation of mutable objects or output to I/O devices (usually—see below).
>A function can perform input or output and still be pure if
>* the sequence of operations on the relevant I/O devices is modeled explicitly as both an argument and a result, and
>* I/O operations are taken to fail when the input sequence does not describe the operations actually taken since the program began execution.
>The second point ensures that the only sequence usable as an argument must change with each I/O action; the first allows different calls to an I/O-performing function to return different results on account of the sequence arguments having changed.

The haskell library ecosystem is composed almost exclusively of small, toy-like, low-quality libraries while everyone else's language's library ecosystem is composed for the most part with large, multi-manyear libraries, as well as a healthy amount of medium and small-sized libraries; almost all of which are usually well-tested and well-tuned for best performance using the language.

removing side effects does not make a language pure, all 'pure' functional programming languages have an environment, this environment is mutable because it is assigned values. you can continue to assign values in this environment using the same name as old values because this environment maintains an immutable record, the actually names that values hold means nothing and is just syntactic sugar. you could create a Haskell program where every variable has the same name, this does not affect the underlying environment. the only programming language that is truely pure is the lambda calculus because the lambda calculus has no environment and even the concept of a number has to be implemented as function calls

>>52179480
No, because there's a recursive fibonacci that uses O(1) space like the iterative one. Every iterative solution has an equivalent recursive solution. Always. They're identical in power, it's just that one may be more appropriate than the other.

The shittyness is caused by pythons numeric weak typing.

Yes? It's not inside a function, if that's what you're complaining about, but it's valid C syntax if you replace all the \\ with //

Then you need to actually try doing floating-point arithmetic in other languages before you claim it happens only in Python, you dumbshit

that explains why you're advocating using 46 year old technology. Here in 2016, we've got more advanced technology. Don't worry, American universities will donate all our old textbooks to you in a decade or so, once we've translated them to your 3rd world pig latin
>>52180037
Thanks. And by the looks of it, it should be enough for an experienced programmer to get into this language basics. But that's just how I like to learn.

>no, just shitty python.
Maybe you should learn your english, but you see were it says that the innaccuracy (which still prints accurately) is only for floating-point arithmetic? When you said, no only in shitty python, it means you think it isn't a property of floating-point arithmetic, but just the way python works. I'm so sorry Python is more popular than your meme language
Someone mentioned project euler a bit back
are you supposed to solve these problems with unlimited processor time or such that you can execute your program and compute the answer from scratch in a few seconds?
Finally did that circle of life
won't post code since i'm honestly ashamed of it, it's shit
>>52180238
Project Euler guy says somewhere it should all be possible in under a minute, if it takes longer, consider altering your algorithm
I mostly work on back end web-dev, but as part of my thesis for Uni my project includes doing a lot of front end work. So I thought I should make some mockups of the website in Photoshop. but I've never really used Photoshop before. how hard is it to create a PSD of a website in photoshop? are there easier ways? I was consider just drawing the fucking thing and scanning it to put into my thesis.

They're challenges, not demands.

You're not supposed to brute force it, no.
Here's one:
(((((7)^7)^7)^7)...)^7
etc., where there are 1000 exponents. What is the final digit of the resultant number?
>>> from decimal import Decimal
>>> i = Decimal('0.1')
>>> n = Decimal('0.2')
>>> i + n
Decimal('0.3')
>>> float(i + n) == 0.3
True

why is Java the retarded step brother of C++?
does it have any redeeming factors to make it useful in the workplace?
I'm a senior in Highschool, and in my third year of our CompSci course, and all we've learned is Java. I've dabbled in C++ and PHP in my free time, but as I use Java every day in class, I am much better at it.

It's accurate without anyway. The temporary innacuracy is a remnant of C programming>>> 0.1 + 0.2
0.30000000000000004
>>> print _
0.3
>>>
>>52180234
>but you see were it says that the accuracy
I never said it was not accurate, it's just annoyingly long. And while python does this because it's shitty, it's not the only shitty language out there. My apologies if I led you to think this.
Honestly it's a little subjective, but I feel by default huge print outs like that showing tiny rounding errors should not be default.
>I'm so sorry Python is more popular than your meme language
LOL. The best thing about python you can think of to make me feel jealous is that it's popular. I'll grant you that, that is by far the best thing about python.

Typical American answer. I'd like you to check which of our currencies is more valuable. Google that. Have fun confirming your own stupidity.
> 46 year old technology
Weird how this 46 years old tech does things faster than your "advanced technology" adapted for teenagers to work with.
Again typical Amerifat defending with senseless shitposting. What's next? Youre going to appeal to the "m-muh freedoms" meme? Good to have a laugh at.
So apparently Rust is very bitchy about what it does and does not allow for "return statement without explicit return keyword". I have thus decided that if I am to further explore this language, I will just use an explicit return statement for everything, just as I would in C.fn average(a: i32, b: i32) -> i32 {
// If a and b are not the same sign, we can safely add without overflow.
if (a < 0) != (b < 0) {
return (a + b) / 2;
}
// Otherwise, we take advantage of a particularly useful mathematical
// property: (a + b) / 2 is the same as (a/2) + (b/2). We will use a
// modulus to account for averaging two odd numbers.
return (a/2) + (b/2) + (((a%2) + (b%2)) / 2);
}
fn main() {
for i in -10..11 {
for j in -10..11 {
println!("Average of {} and {} is {}", i, j, average(i, j));
}
}
}
>>52180304
Actually, the reason why python prints like that is because it uses a limited precision + rounding in the print routine whereas it shows the actual value in the repl print.
>>52180283
it's much faster and easier to develop a program using java than C++
>>52180304
print rounds it>>> 0.1 + 0.2
0.30000000000000004
>>> print 0.1 + 0.2
0.3
>>> print 0.1 + 0.2 == 0.3

if you're wondering what's wrong with it, it has no caching. Basically it works by drawing a hexagon and for each point drawing a circle then adding it to a list. I then go through the list and for each point, draw another hexagon, draw the circles for that. These hexagons are invisible of course.
Problem is it goes through the list each time. So for a 2 deep hexagon it takes 36 + 6 tries (6^2, 6 being the sides in a hexagon). Next time its 6 + 36 + 36*6 tries... etc. Should be simple enough to make it not loop though, speeding it up loads

C is generally retarded as it's hugely unproductive for the vast majority of programming problems today. For embedded stuff and high performance drivers etc, it's good. but not much else.

>>52178963
That misses the point of C. C is supposed to be a high level version of assembly where you get the power of assembly, such as memory management, whilst allowing you to write programs in an abstract way such that you can compile the same C code on many different CPU architectures without having to rewrite the whole code.
