I'll take a guess and say because you're pushing

, which is of type

, into is_aiv when you need to push an object of type

into is_aiv.

It's me all the way down.

Doing a java project.
I have some code that might be shared my some classes, some of this code are general purpose algos.
I don't want to put it in some class that i then have to extend because i feel like this methods should be private if put into those classes and testing is going to be a pain in the ass.
Should i just make a myproject.Util package and stuff that code into various single purpose classes? Seems the cleaner method for testing.

I'm fairly surprised the code with a lookup table is faster by an inch than the "unrolled", more imperative version. And really surprised the version with cached size and memcpy is twice as slow as either of the others.

You're clearly new here if you think that isn't par for the course.

>>58867256
Thanks, I'll look into that.

The GNU extended inline assembly documentation is, how you say, a bit garbage.

>>58866724
Make your common functions public static. Of course, you'll have to deal with the fact that you must include them in a class, but you don't have to instantiate the class to access these methods, so I guess that fits your case.

>>58867688
Either will work. I usually prefer to create a single unique identifier, but as long as your composite key is unique, you will be fine. It is just a matter of preference.

Though not creating a new single ID would reduce the amount of data you need to store, so there is that to consider.

>>58867688
You ought to have a Channel ID key. You can make it an auto-incrementing identity column.

The issue is that these are behind private corporate firewalls and so are unable to be shown on any of these reports that only look at public webhost servers.

#include <stdio.h>
#include <stdlib.h>

int evil_code(void)

    return 0;
}

int read_req()
{
    char buf[16];
    gets(buf);
    int i = atoi(buf);
    return i;
}

int main(void)
{
    int x = read_req();
    printf("x=%d\n", x);
    return 0;
}

How do I use this buffer overflow to overwrite the return address of read_req and jump to evil_code instead of back to main?

Just came across this one. Write a solution to each of the following problems:
1. Read a string and output all combinations of it's characters.
2. The "8 queens" problem. Print all the chess configurations where eight queens can be placed on a board without attacking each other.
3. Given N, list all the prime numbers up to N.
4. Write a subroutine to multiply two arbitrary-sized matrices together.

In each of the following languages:

this applies to any person who hasn't seen every anime is existence, which is virtually impossible.

there is no such thing. the very fact that you know you should avoid it means you have watched at least some of it. you can't tell for sure otherwise.
there can only be "anime you should avoid continuing" but the phrase itself implies that you have started watching.

Why even ask what to watch then.

I've been learning Java for about 3 weeks and decided to mess around outside of the exercises in the course I'm using. I'm trying to use a method to grab the first entry in a list, if it were in alphabetical order, but for some reason I can't even get it to output using .get(0) without the method.

I'm sure there's a better way to go about it, but what I'm concerned with is why this doesn't work. Excuse the messiness and experimentation in it.

import java.util.Scanner;
import java.util.ArrayList;
import java.util.Collections;


public static String listAlpha1(ArrayList<String> list) {
        Collections.sort(list);
        return list.get(0);
    }    

    public static void main(String[] args) {
        Scanner reader = new Scanner(System.in);

        System.out.println(""); //Prints a line break
        ArrayList<String> bodyParts = new ArrayList<String>();
        System.out.println("Let's make a list of body parts.");
        System.out.println("When you're done, just hit 'Enter'.");        
        while (true) {
            System.out.print("Enter a body part: ");
            String part = reader.nextLine();
            bodyParts.add(part);
            if (part.isEmpty()) {
                System.out.print(bodyParts.get(0)); //This is the only time .get() works
                break;
            }
            
        }
        String alphaFirst = listAlpha1(bodyParts);
        System.out.println(""); //Prints a line break
        System.out.println("Excellent. We have our list.");
        System.out.println("The first part alphabetically would be: " + alphaFirst); //Only prints the line in ""'sort
        System.out.print(bodyParts.get(0)); //Does nothing
        System.out.println("Let's check that against the list. Just to be sure.");
        
        for (String partprint : bodyParts) {
            System.out.println(partprint);
        }

Does .get() not work outside of the brackets where you first add the entries?

What's the best way to merge multiple sorted lists into a single sorted list?

>>58869423
>How do I use this buffer overflow to overwrite the return address of read_req and jump to evil_code instead of back to main?

buf is allocated on the stack, as well is i. Use a disassembler to find the address of the evil_code function. Then pipe 4 + 16 + sizeof(address) + the address to the program. This overwrites the return address that's also on the stack.

>>58866724
Keep your classes and methods small. Say you have a function that parses a tab separated string to an array of ints, just put that one function into a class called StringToArrayParser (or something like that).
Put that class into a util namespace if you like. Make the function internal and you're good.

Check up on SOLID, if you don't know the principles already. (Especially the S, but the rest is important too)

>>58866502
Is it really possible to keep more than one keyboarding style in your head at once?

>>58870189
Not really the case in my situation from the benchmarking I'm doing so far.

I have several hundred lists of several million values each, and the values in each list span approximately the same interval, meaning I end up with a situation where when I'm joining list A with list B and the resulting sorted list would tends to have elements from A and B alternating throughout, every other element being from a different list. Merge sort does better if the lists more continuously span different intervals which makes them easier to merge.

At the moment I make a red-black tree directly out of the first list and then insert all the others and it trumps all sorting functions I've tried.

>>58870235
Is it considered good to be a 'hard worker' were you're from?

>>58870303
>when I'm joining list A with list B and the resulting sorted list would tends to have elements from A and B alternating throughout
This is the scenario where merge sort is ideal, so I don't understand your problem.

>At the moment I make a red-black tree directly out of the first list and then insert all the others and it trumps all sorting functions I've tried.
Are you fucking insane? Giving a sorted list as input to a (balanced) binary tree leads to fucking worst-case behaviour.

Isn't this everywhere?

Easier to work hard.

Muscles create less errors than compiler. Maybe programming isnt for me.

>>58868018
The stats they published are nice and flashy but don't actually have any value.

You could interpret it as working people being active during weekdays and students being active on weekends.

You could also interpret it as technologies used at certain days.

Their whole article being about programming languages used is also pretty vague, since they list math, algorithm, pointers, opengl, recursion, etc as tags in their data.

Also, did they actually take local time zones into account? There can be up to 26 hours difference between two time zones, basically 'delaying' the weekend for more than a day.

>>58870340
>Isn't this everywhere?
No.

In Japan people stay late at their job just for show, often they do no actual work or they sleep there, just to look like they 'work hard'.

In some other countries people spend days doing menial tasks that could be automated in a matter of hours and then time wouldn't be wasted on it ever again.

But now some people realize that working hard has nothing to do with being a good worker, and they value producing a lot of things over taking a lot of time.

I don't know prolog, but you could use a list / array IF that's available to you.

If you have a 10x10 field the array would have 100 entries (0 - 99), you can 'translate' between the index and your x/y coordinates using this formula:
<code>
x = i % 10
y = round(i / 10)

i = y * 10 + x
</code>
