Your post number is 75. For the interests of this challenge, post numbers start at 01 and go up to 00, which counts as 100.
75 / 100 = 0.75

He means nobody wants your roller trash

So I'm working on a webpage, and I need to execute a perl script through a web browser to actually build the HTML.
Problem is that I cannot get apache to execute it for the life of me.
I've made sure that perl-mod and cgi-mod are loaded, I've set "options +execcgi" and "addhandler cgi-handler .cgi .pl" for the sites directory in apache2.conf, and I set chmod 755 for the script.
Every time I try to launch it apache just serves the perl script as a regular file, and Firefox downloads it.

What do I need to do?

Friendly reminder that you should return reference to an object iff:
1. The object itself is passed to the scope as a non-const reference
2. If the object is created within the scope, it is static
3. In no other situation

Reminder that you don't also need multi-return functions, create the expected values first and pass them as non-cost references into the function. These are called out params.

So I want to learn python and was looking around and found the O'Reilly books. Are they any good? Or should I learn somewhere else? Does it teach good practices, scaling projects, python standards etc?

I was also looking to properly learn frontend as i college was pretty shit about that. Where can i learn html/css properly and some meme popular framework to go along? I tried django but making the website pretty was no good.

Also, I have experience as a developer.

you forgot about when the object referenced is not (explicitly) passed in as a parameter but still has naturally greater scope/lifetime than the function, like a member function returning a reference to a data member or member array value from the containing object. or a member function returning a reference to the containing object itself, like an operator+= overload returning *this

>>62343591
allman is the only logical style there.

>>62343651
I think you mean K&R

>>62343682
if K&R had you put align the body contents with either the ( or the following char, it'd be okay.
But how it is normally is just ugly, illogical and not very readable.

>>62343707
it's perfectly readable and wastes the least whitespace

>>62343707
if you have e.g.

if (x) {
...
}

you already get the 2 "separators" - one is the if

>>62343720
>wastes the least whitespace
Oh god, how will i survive not having my source files be the max optimized they can be at the expense of readability.
>>62343728
I just think you need a newline or else things are just too scrunched up. Which is why allman is so good.

>>62343707
>>62343682
>>62343651
I used to do allman as I was introduced to programming with C#. However, when I started doing Swift recently, I realised that allman is fucking horrible and wastes so much space. An entire line for a single { when you know where it starts anyway? Stupid. Really bad design. Looks bad once you are used to K&R.

You're wrong, what you're imagining is just getting in the way. The shape you see is hindered by needless detail. The symmetry is indentation symmetry, which ISN'T shared by allman since it means you have two lines at the start and one at the end (on either side of indentation)
The complaint that the different length of the lines is an issue is nonsense.

C can't either which is also a popular language. I don't see your point.

Quick Python style question.
Which one of these would you write:

if not some_condition:
    return None
return something

or

if not some_condition:
    return None
else:
    return something

?

>>62343872
None

>>62343872
I don't speak snek but a way to do this is a ternary

return cond ? something : something_else;

>>62343842
Wtf is this senseless crap, good job getting a good job with that code styling lmfao

>>62343872

if some_condition:
    return None
elif not some_condition:
    return something
else: 
    return 5;

>>62343907
Oh yeah, I forgot about the ternary operator. Not really a fan of it in Python, but it fits for me right now.

>>62343872
if not some_condition is an error condition, the first.
if not some_condition is a "typical" condition, the second.

From the Zen of Python: "flat is better than nested"

Therefore you should try to nest as rarely as possible, so omitting the else branch is the correct choice.

I got into programming because I had an interest in cybersecurity and making videogames, but I know trying to make a living off of making videogames would be suicide.
I'm thinking of also getting involved in research, specifically at my college maybe? Coding in and of itself has always caught my interest but it feels like if I go into a jack-of-all trades and learn everything I won't be "good enough". I keep getting told to specialize, specialize, specialize, but it makes more sense to be flexible and adaptable so I'm not stuck trying to find one job out of hundreds under the degree.

Anon, if you live anywhere in the U.S, go into business. It's a capitalist country.

Everyone here codes for fun. Only a selected few in here probably have a job in programming and that's in Fiver, Upwork or an actual Salary based job.

Truth is, Whatever language you're being taught is probably the most flooded and can be done better than you by others.

Now you said something about Cybersecurity. Same. I'm doing the same thing. Except my dumb ass is currently attending a college that has Cybersecurity under the College of Business. Which means I won't learn Jack shit of programming/networking, except for my final year here.

I know C++, Python, HTML, CSS, learned by myself. If I could do it, holy shit imagine how many others could.

Trying to learn Networking through Cybrary dot it so I can get CompTIA A+ and Networking Certificate.

I have a list of other useful links given to me from an internship with the Department of Homeland Security in case you're interested. Just sit tight.

Go to Github
pick up any Python code
Try to "reverse engineer" and you'll understand how easy it is.

Programming is just "PC, do this if this and this and this and this, except if this and this and this and this, while doing this and this and this and this, also if this and this and this and this, do this and this and this, except if this and this and this."

Follow the code, if you can't understand a variable or function, google it.

Also, Python and other languages work in a way where you can't create everything, so people create libraries so you can get the job faster.

The first few lines of code is just accessing that library. Instead of writing 100 lines of code to create a square, you could just grab a library and create one in 2 lines.

Here's the list of many libraries

where's the beautiful and cleanly designed language? is it behind the C# logo?

Can we just accept that both C# and Java are pajeet languages? There's 1.3 billion poos on this planet and they're bound to end up using all languages. The only non-pajeet languages are NEET meme languages like haskell and lisp.

PHP is undeniably the most pajeet though.

There's no excuse for a modern programming language to be verbose. It doesn't matter if the programming language has a GC or not.

Rust might be good for actual systems programming, but it's too much a hassle for user space software.

When you do pic related does it store values in trans_unit, quarter and trans_amt or just checks them without storing?

>>62347812
It evaluates the function as it would in normal code and sets the "status" to the return value of the function.
The actual storing happens inside the function anyway. It doesn't matter how you call it.

Which of these is worse?

Vec<Rc<RecCell<Box<Trait>>>>

// no generics lol
// this would be even more hellish without void* but let's assume I never want to reuse this code for anything elsea
struct Vector
{
    struct Rc
    {
        struct Box
        {
            void *data; // impls trait;
            struct TraitVtable *vtable; // let's assume this is already defined
        }
        *data;
        int *refcount;
    }
    *data;
    int size, capacity;
};

struct Vector vector;

A good type system costs nothing, but C's type system is trash. Safety is secondary - expressiveness and conciseness is what matters.

>>62347911
I agree with you in principle but the end goal here is horrible. Nobody should ever write code like this. Especially not concerning highly utilized components like vectors and representations of geometric shapes.
And reference counting on top? Lord have mercy.

Literally just C with better standard library, like define the fucking API for threading and and compiler flag for platforms that supports it. Now do it for utf8, directories and file paths, basic data structures.
Maybe smarter compiler like, recursive macros and maybe some kind of modules instead of headers.
Saner types without the _t ending so every faggot doesn't have to rename uint32_t to u32.

That's because you're only seeing the Box part. You still need to have a Vector struct and a Refcount struct

};

struct RefCount
{
    void *data;
    int *refcount;
};

struct Vector my_vector;

// now each time you want to use something
Box box = (((Box*) ((RefCount*) my_vector.data).data);
box.vtable->traitImpl(box.data);

With GC or affine-types, you can prove that your type system ensures that no memory will be corrupt etc. But as soon as you allow pointer arithmetic, all those proofs go out the window and every operation has the capability of being completely undefined.
Its difficult to make a language today with the same level of unsafety as C and be taken seriously, but the problem is that fixing that unsafety causes the aforementioned problems.
e.g., putting the language in a memory safe VM makes the language less efficient, usually removes any chance of an ABI (because the language lives in a VM world that is not the same as the linux C world).
Trying to do without a GC and still maintain memory safety requires introducing a lot of extra things to the type system. Rust actually does a good job of making the borrowing system easy to use; a naive approach that didn't value "ergonomics" would be twice as awkward and three times as unreadable. Then introducing things like generic requires name mangling etc

Alternative: find the plane such that the vector M1->M2 is its normal and M1 is a point on said plane. Project N onto this plane. If the projection has a length close enough to 0, N can be said to be on the line (M1,M2).

Could I just ask why C++ is so ugly?
Why are there so many -> operators?
Why can I violate scope with ::?

#include "Pizza.h"

#include <list>
#include <algorithm>
#include <string>
#include <iterator>

using namespace std;

Pizza::Pizza() {
    ;
}

void Pizza::makeDough(string dough) {
    this->dough = dough;
}

void Pizza::addSauce(string sauce) {
    this->sauce = sauce;
}

void Pizza::addCheese(string cheese) {
    this->cheese = cheese;
}

void Pizza::addTopping(string topping) {
    toppings.push_back(topping);
}

void Pizza::addToppings(string* toppings, int n) {
    for (int i = 0; i < n; i++) {
        this->toppings.push_back(*(toppings + i));
    }
}

void Pizza::print() {
    cout << "A nice-a pizza with ";
    cout << this->dough + " dough, ";
    cout << this->sauce + " sauce, ";
    cout << this->cheese + " cheese, ";
    cout << "with ";
    list<string>::iterator iter;
    for (iter = toppings.begin(); iter != --toppings.end(); iter++) {
        cout << *iter + ", ";
    }
    cout << "and " + *iter;
}

Pizza::~Pizza() {
    ;
}

How ugly/retarded is this?

 
    if (tic_tac[1][1] == 'o' && tic_tac[0][0] == 'o' && tic_tac[0][2] == 'o' && tic_tac[2][0] == 'o' && tic_tac[2][2] == 'o')
        winner = 'o';
    if (tic_tac[1][1] == 'x' && tic_tac[0][0] == 'x' && tic_tac[0][2] == 'x' && tic_tac[2][0] == 'x' && tic_tac[2][2] == 'x')
        winner = 'x';

I couldn't come up with a loop that check diagonals in 3x3 board for a winner in tac tac toe. Rows and columns were easy

>>62349040
>Why are there so many -> operators?
Because that's how pointers work. use references if you don't like it.
>Why can I violate scope with ::?
That's not violating scope, that's just entering a scope.

>>62348839
Horrible.
Hint: use vector colinearity

>>62349045
Examine a three by three board:

[ ][ ][ ]
[ ][ ][ ]
[ ][ ][ ]

With a 2d board, there are only two diagonals; Forward slash and Backslash.
You could model these with this:

for (int i = 0; j = board.length; i < board.length; i++, j--;) {
   board[i][j] == 'x' || board[i][j] == 'o';
}

for (int i = 0; i < board.length; i++) {
   board[i][i] == 'x' || board[i][i] == 'o';
}

Just check if they are similar, then set winner = turn;

Finding a plane alone requires gauss elimination and potentially parametrisation.
Returning the negated bool value of the sum of the length of M1N and M2N would be simpler.

Reminder to define your functions to handle vectors and then add function to handle the single item case.
Instead of first defining function that operates on single item and then making function that calls that single item handler on vector of inputs.

>>62349058
References look almost as bad as ->.
I understand that most of C++ is just definitions over C, and I know that most objects are really just pointers to structs, but my god, it feels like a clusterfuck.

I'm coming to this from two ends: nice and fancy java and the barren wastes of C, and it feels really wrong.

As I said, typical brainletism.

C++ has many faults, but it also has RAII.

>muh reference types
C and to a lesser extent C++ make it easy to see what's a value and what's a reference.

>>62349121
I will study these, thanks

>>62349290
It's not ambiguous in Java. You just need to remember that primitives are values, objects are references, and what the set of primitives is.

Of course this has horrible implications for performance because you can't pass objects by value.

>>62349241
Okay, how would you project it withoutvector multiplication

>>62349326
It's especially shit when it comes to generics, because then you have to start boxing things.

Still, better than C# with its struct bullshit. Or D.

Both are ugly.

>>62349336
>withoutvector multiplication
What do you mean by "vector multiplication"? You can do it with a dot product, if that's what you mean, and I see no problem with that. Not saying it is the best solution, but it's not "horrible".

>>62349158
>>62349637
Implementation of (>>62348839):

n = unit(m2 - m1)
v = p - m1
v2 = v - n * dot(v, n)
return dot(v2, v2) < epsilon

This solution uses only one square root, and it has the advantage that the normal can be reused to test against multiple points.

Wanted to learn functional programming and downloaded Haskell.

Right now, I'm having trying to something trivial like finding the largest 2 of 3 number, but I'm having a hard time structuring the function to do so. There's just something about it that isn't clicking with my brainlet mind.

>>62351343
How would you do it in an imperative programming language? I don't see how it would be much different for this specific task.
