111 isn't prime (3×37).

Or I'm misunderstanding the problem, and it is actually stupidly simple.

>>60875057
What happens if you ask for a 13-character string?

>>60875071
she wears the key to your heart on her chest.

>>60875091

That's 11 and 13 concatenated.

>>60875091
That's 11 and 13 you dumb monkey.

>>60875104
But 113 is prime, and still contains 11 and 13 in sequential order, as substrings. I thought it might be something fancy like that, where each substring needs to be prime too.

But it sounds like it is actually just a stupidly simple homework problem.

>>60875140
Are you only pretending to be retarded?

>>60875064
not homework. actually was the equivalent of a fizzbuzz test.

here was my solution:

#create a string n characters long composed of the first prime numbers in order
class PrimeStringSieve():

    #estimate of highest prime number to search for
    SEEMINGLY_MAGIC_CONSTANT=3.1415

    _outString=''

    def __init__(self,StrLengthToGen):
        def sieveSize(str_length):
            return self.SEEMINGLY_MAGIC_CONSTANT * str_length + 1
        def toString(array):
            string=''
            for each in array:
                string+=str(each)
            return string
        def sieve(size):
            array = [True] * size
            for each in xrange(3,int(size**0.5)+1,2):
                if array[each]:
                    array[each*each::2*each]=[False]*((size-each*each-1)/(2*each)+1)
            return [2] + [each for each in xrange(3,size,2) if array[each]]
        self._outString = toString(sieve(int(sieveSize(StrLengthToGen))))

    def fetchString(self):
        return self._outString[:50]

If I use stack it segfaults on very large values.

Make it so that you have to match the string length n exactly, and the primes doesn't have to be sequential, but just in growing order.

 *   Examples: getByte(0x12345678,1) = 0x56

I was messing around and can do:

#include <stdio.h>

int main(void)
{
    int a = 0x12345678;
    int b = 0xFF; // Bit mask.
    int n = 1; // The nth byte of 'a'.
    
    b <<= (n * 8); // Shift the mask into position. 

    a &= b;

    a >>= (n * 8); // Shift the nth byte to be LSB.

    printf("%x\n", a);

    return 0;
}

But multiplication using * isn't an allowed operation. What do, /dpt/?

>>60876725
Think about what << does

>>60876725
Multiplication by 8 is equivalent to left shifting by 3.

Anyone know why the fuck Netbeans is such a piece of bloated trash? I'm trying to work through this MOOC but the entire time it's been constantly freezing up for 10-30 seconds at a time or just completely crashing. I tried turning off some of the 50+ plugins it had, but every time it said it would have to disable the 2-3 plugins that I actually need due to dependency issues or whatever. It's really driving me fucking crazy, I want to do the second part of the course but I can't deal with this shit anymore, it's killing my productivity to have to sit there waiting for it to unfreeze every time I type a bit too fast or run something.

Well, if you consider 2 cat 3 = 23, and is prime, and 23 cat 5= 235 and is not prime, the length is 2 ("23"), or 3 ('235") if starting from first non-prime string. No prime besides 5 has its last digit ending in 5.

I'm doing some coding challenges to teach myself javascript, is this good practice?
If I was doing this in a C-like, I'd just make a simple anonymous struct array and sort it in place, but apparently this isn't possible in JS, it forces you to create a bunch of redundant intermediate arrays.

function order(words)
{
    var find = function(str) {
        for (var i = 0; i < str.length; i++)
            if (str[i] >= '0' && str[i] <= '9')
                return parseInt(str[i] - '0');
        return 0;
    };
    var arr = [], ret = [];
    var sp = words.split(" ");
    for (var i = 0; i < sp.length; i++)
        arr.push({ idx: find(sp[i]), str: sp[i] });
    arr.sort(function(a, b) { return a.idx - b.idx; });
    for (var i in arr)
        ret.push(arr[i].str);

Do you mean that the compiler will optimize? What about for dynamic languages like Python? For example, bitshift right by 1 is faster than "// 2" in Python.

My mom got yelled at by her faculty representative for suggesting she should take a cobol course. She was told she shouldn't waste her time or intellect with languages for morons like cobol.

Right now i'm using vue.js and flask/python

vue.js uses the virtual dom or something, like react and angularjs. Really nice to use, pretty good uptake in the community so tones to copy from.

https://github.com/vue-bulma/vue-admin

django is the most popular web framework for python, flask is the same but barebones w/ lots of community extension (for database/auth/etc anything that would be in django. I like it because it's easier to approach than django, literally just glue between werkzueg and jinja2

http://djangobook.com/tutorials/django-overview/
http://flask.pocoo.org/

other python frameworks (tornado, pyramid) are probably better if you're working on something bigger

http://www.tornadoweb.org/en/stable/
https://trypyramid.com/

I worked on this thing that used web2py, seems ok

i'm kind of learning some nodejs atm. it's okay and really nice only working in javascript. switching back and forth between python andjavascript is inconvienent, and trying to do websockets stuff

https://nodeschool.io/#workshoppers

>>60877468
Who knows. Languages like python have entirely unpredictable performance.
I recall there being a difference between their range functions somehow. Like xrange() being massively faster than range(). Despite being rather similar in usage and intent.

>hardware deal with it
There could be many things she means here. But yes most likely your optimizer will deal with it.
That applies to shifting VS power of two multiplies.
It's only if both the values of the operation are dynamic and can't be value range optimized to determine that its a multiple by a power of two that you may want to choose to shift instead of multiply.
The easiest way to do things is always write wherever you know is the real intent. It's not that important to consider before you have a good reason to. It's a trivial change in any piece of code.

In python2, range() made a list of the numbers in the range, while xrange() was an iterator. So range() took up a fuck ton of memory if the range was large.

Your programs only perform in unintended way if you're retarded. i.e. if you are checking for inclusion of a value in set, use a fucking set, not a list. I've seen a million retards do that.

how can i design a database table ('trust') that has many users connected to it, but only one company associated with it?

e.g.
i have:

(company | company_id, etc ) <--> (trust | trust_id, company_id, user_id)

but in the above current form you can only have 1 user_id per trust -- how would i make it so there can be multiple user_ids associated with the single trust?

>>60875018
No. I cannot.
Do you know why?
Because you just described all programmers.

>>60878133
remove user_id from trust, make a third table that maps
(user_id, trust_id)

I started doing some work on an ai. I never did anything in that direction because I was always the opinion that we dont know enough about us and how we interact with the world on a philosophical level. but now, after watching maps of meaning from Jordan B. Peterson I actually conceptualised an ai that can find its way in a world and have interactions with objects in a primitive way (for example: kick it -> evaluate -> remember the outcome) and acts if it has a body. I intend this to use in a game, if I can make it work.

yes because that's what they're called and anything you can propose as alternative is also a paradigm
>inb4 "for simpletons maybe"
no, for anyone
>inb4 "maybe if by "better" you mean shit"
no I mean better

no, including all of them

The kernel is full of badly implemented OOP, for example http://www.tldp.org/LDP/khg/HyperNews/get/fs/vfstour.html .

>>60881848
>OOP is better than literally any other paradigm.
Only if that other paradigm is POO itself.

All it takes is a chronic shitposter to ruin a thread.

About you. If you aren't a redditor don't act like one.

This is a reddit-free zone as of right now.

Get out of this thread then? Why are you on a general thread if you dislike reddit in the first place?

I'm not a reddit citizen though. And this is officially a zone which any non-redditor can use freely.

Keep going, gate keeper. I actually want /dpt/ to die (just like you).

/dpt/ spreads misinformation, this thead is best dead

Seriously, it's like you guys are actively trying to kill /dpt/.
Please stop.

killing /dpt/ is necessary.
