>>58962879
D is dead. Nobody uses it.

How many hours should I realistically be putting into learning an OOP language to be successful in a CS degree

>>58962907
POO has nothing to do with computer science.

>>58962879
Pretty good if you don't mind it being completely GC free (yet). I find it much better to use over Java or C++

>>58962833
it's done but i'll publish it only when my dumb website is up.
which may take from half a year to never.

So guys I want to program a little bot to make alts for some japanese autism game. First thought would be that I have to sniff the packets sent and received by the actual game and then analyse what's in there so that I can make my bot send the correct commands and interpret the information the server sends. Thing is: I have no idea how I would go about doing the packet sniffing. Would wireshark or some other comparable tool work just fine? And if yes, anyone have some good site to read up on that stuff?

Of course if my thoughts are stupid I am open to a proper way to get the results I want.

>>58962817
Still working on WPF. It's a nice framework but I think I'll leave the project without much more technology features anymore, just content, it starts doing most of what need, barring some file saving I/O features that are basic technology.
Thinking of doing something multiplatform, for a family business site, it has to do basic things like promotion and booking of services.
I thought of going mobile platforms, but sad thing is the cesspit of the web is probably more optimal for that kind of thing.

Making an algorithm which calculates the root of a number using the babilonian method in python 3.

def babilonian(n):
    guess = (n-0.5)/2
    def method1(k,u):
        h = k/u
        u = (u+h)/2
        print(u)
    while guess**2 != n:
        method1(n,guess)
    return guess

print(babilonian(5))

The problem is after the first attempt of method1, it keeps returning the same number in a infinite loop.
What the fuck am i doing wrong?

I thought Pajeet was an authority on programming.

while guess**2 != n <---- this is always true
        method1(n,guess) <--- thus, this is will run forever

something i just whipped out earlier today re: implementation.

As a straight white male am I pretty much SOL for getting hired in tech now? Everywhere I look people are saying that H1Bs are taking over everything, and if it's not H1Bs, its diversity and gender quotas.
Are these just memes perpetuated by incompetence?

>>58963034
my heart sank when i saw the missing bracket as i had just pressed post

>>58962985
Pattern matching is not a problem.

My problem is that I have never done anything like packet sniffing. Or infact anything related to doing stuff to a running program to the outside (like trying to read the memory allocated by the program and just trying to make sense of the shit in there).

But I take that as "Yeah, wireshark works just fine"

>>58962983
Right, I know it's always true but it shouldn't be, method1 process the number once and returns the same number everytime

>finite automata
what about infinite state automata?

>>58962952
Integers are immutable in python, when you do `u = (u + h)/2`, `u` now references a new object, while guess remains how it was. to get around this return u from the internal function and set guess to that.

def method1(k,u):
        h = k/u
        u = (u+h)/2
        print(u)
        return u
    while guess**2 != n:
        guess = method1(n,guess)

>>58963065
You know method1 doesn't modify it's parameters? Python is call-by-value

>>58963065

def Babylonian(number):
    if(number == 0):
        return 0

    g = number/2.0;
    g2 = g + 1
    while(g != g2):
        n = number/ g;
        g2 = g
        g = (g + n)/2

    return g

>>58963088
Python is pass by referene however the assignment operator always reassigns the label not the value.

What are you doing? The algo is simpler than that.

def bab(n, v):
    x = v
    for i in range(0, n):
        x = 0.5*(x + v/x)
    return x

print(bab(10, 2))

>>58963138
I try to avoid them but there's a time and a place for everything.

>>58963327
Or with a convergence test:

def bab(v, e=0.001):
    x = v
    old_x = v + 2*e
    while abs(old_x - x) > e:
        old_x = x
        x = 0.5*(x + v/x)
    return x

print(bab(2))

Why?

Is there basic programming work available online somewhere? I'm willing to work for less than min wage--I just want to do some light development for a bit of pocket money. So far all I can find is Pajeets doing bad work for a dollar an hour, and if that's all that there is, I'm not interested. I'd appreciate any recommendations or advice.

say I would add 1000 ints to vector.
I would have to call 1000 mallocs and store the pointers to vector.
Or I could have this one malloc for the vector memory and store the 1000 ints there.

If you're not willing to make a sacrifice, yes. Comfy days of easy jobs are over. Now you need "people skills"

>Everywhere I look people are saying that H1Bs are taking over everything
Shit shops like Oracle, yes.

>and if it's not H1Bs, its diversity and gender quotas.
Given the same skillset etc, a recruiter will forward female CVs/resumes ahead of yours, and the company reviewing will generally prefer those over you as well. If you know what you're talking about you're already going to sound better than 90% of applicants.

it's not my own special snowflake integer type it's short hand for standard type.

>>58964156
By just typing unsigned instead.

It's still special snowflake shit. All you're doing is adding extra cognitive load and possibly confusion for other programmers, just to save a few characters.

It's the name of the general purpose register in x86 used for storing return values when they are integers or pointers. It also functions as an accumulator register for certain instructions.

Seems to me like that's what you're doing, you just have to make sure to call this function in main and do something with the returned value.

>>58964456
2nd

>>58964470

int maxGrade = findMaximum(grades);

This takes the variable grades, calls findMaximum and passes it in as an argument.
Then it takes whatever value is RETURNED from findMaximum and stores it into maxGrade.

I don't really understand where your confusion or problem is.

>>58964387
bump, I need advice

>>58964564
exactly so why make your own typedef when size_t does the job (and does it correctly across multiple platforms due to the nature of size_t corresponding with sizeof)

>>58964600
because size_t is offensive and coders should not use it.

>>58964610
Error tells you exactly what's wrong - you're trying to pass an int argument to a function which accepts a pointer-to-int

>>58964592
use google protocol buffers or cap'n proto

or just dump to a file with in a simple binary format

>>58964610

int findMaximum(int grade[])

You're trying to pass in an int. not int[]

>>58964610
The problem is not what you thought it was though, you're passing an integer to your findMaximum function when it expects an array of integers.

i mean you can use sqlite, and probably should.
it depends on your performance requirements.
if you doing it once a minute or so you're ok with sqlite, but if it's a constant hot loop better use a non-textual, binary format.

>>58964614

If size_t is so offensive to you, use it's signed counterpart, ptrdiff_t.

>>58963845
Note: SBCL can detect type errors at compile time. It can also treat macroexpansion errors at compile time. I can't speak for other compilers though.

the c11 rsize_t is the most kosher of all typedefs

Please do not recommend XML over JSON. XML is bloated and obsolete.

the xml spec has weird ideas about whitespace and such and other arcane semi-ambiguities

Why rsize_t over size_t?

>>58964786
>XML is bloated and obsolete.
for you

>>58964808
mostly semantics, it's supposed to be a strongly typed alternative of size_t for object size (scale) in opposed to an index or offset.

Portability. A long on 64 bit Windows is not a long on 64 bit Linux. An "integer big enough to store the size of an object" is also going to be different on different platforms. The base types in C are wholly inadequate for anything specific. You can't even make the assumption that int is 32 bits.

In return, I shall give you the first meme I ever saved on this machine.

It was something simple, like reversing a string without a temporary variable.
The key points were knowing C syntax by heart, and avoiding an off-by-1 error.

I'm just saying practicing to program on paper without any references can have real-life benefits, like for me getting that job.

>a fucking leaf

Any good books on how to think like a programmer/software developer? I am still a beginner, and while I understand the questions/problems, I have a hard time translating my "thoughts" into code. Hope that makes sense. It's kind of like trying to play what you hear in your head in guitar. Thank you in advance. Preferably in C, since is the language I am trying to master at the moment.

kek'd. Thank you based anon.

As boring as it may be, like you should practice your scales, chords and picking technique over and over again,
practice elementary algorithms and design patterns (in a general sense), over and over.

Skill comes 1/3 from learning new information and 2/3 and experience.

That's also why Asperger's have a hard time in social situations because they try to derive it from information and not practice, but socializing is highly irrational. So you need to practice.

Think of it this way: if you practice the programming "vocabulary" and grammar over and over, it will be much easier to formulate sentences.

read an algorithms book and write lots of code read more programming books

i would have a loop going through the string in reverse and storing it in a new string

>>58967730
Thanks a lot for the analogy, fellow anon guitarist. It's makes a ton of sense.

>>58967745
I do, indeed, need to practice a bit more. At least 1 hour every day. Thanks a lot anon.

You had to reverse it in-place using pointers.
They wanted to see the candidate has a basic understanding of pointer arithmetic.

>>58967759
Thanks for the suggestion, anon. Do you recommend me an specific algorithm book? I was thinking on buying "Introduction to Algorithms", but if you know a good one, even better.

>>58967690
I'm a time traveler. Send me your first anime pic and I will get the information from him.

>>58967775
ohh i never used pointers before or know what they are I only program in Java

>>58967778
that book is a pretty good one I would recommend reading it giving it a go

>avoiding an off-by-1 error
that's rich coming from someone who didn't avoid it himself

Would I get bonus points for calling the atomic swap intrinsic?
