1. Place all games/programs/scripts in one or more "well known locations"
2. Add all these locations to a variable that you search later, let's call it PATH
3. match user input and exec() the matching program
4. ???
5.

apt-get install bash

So i want to write a console application, it will take a certain input and run a sort of unique program for that input. For example (this is not the thing i wanna do but its similiar to the idea), a console app that would take something like the name of a game e.g. pong, space invaders, and then run the "pong" subprogram. But in my case there will be a lot of subprograms, how would i do this without loading it all into the program at once, is this the type of thing you use multithreading for?

i hate that fucking picture

>>57060454
If each game is a separate program, you can just tell your console app to read the input, parse it and figure out which game the user is talking about, then just start a process for that game.

Apparently I was in the old thread. I've just started coding and I can't seem to figure out how to fix the problem. So for this exercise i have to encrypt a text file. The code has to know how which character there is and if the same character comes after, it has to say the letter+number of occurrences. So banana will stay banana but sleep becomes sle2p. But all it does is put 1-s after every character.

 invoer = open(original, "r") 
    uitvoer = open(doelfile, "w")       
    
    kar = invoer.read(1)
    i = 1
    while kar:
        for line in invoer:
            for kar in line:
                prevkar = kar
                kar = invoer.read(1)
                if kar == prevkar:
                    i += 1
                
                                                           
                if kar != prevkar:
                    i = 1
                
                uitvoer.write(prevkar+str(i))
                kar = invoer.read(1)

>>57061040
(I don't actually speak Dutch)

if kar != prevkar:
    i = 1

If you look at this, i is getting set to 1 when you run into a different character BEFORE you print it out

So if you're using "sleep" as an example, when your code hits that final p character, your i variable is at 2, but gets set to 1 before you print it out, which is why you get sle1p instead of sle2p

>>57061115
well that's even worse than what you described
i'll be more direct than i'd like: i don't see why you call ".read" ever. with the "for" loops you're iterating over the lines and in each line you iterate over the characters. that should be enough to do the job
so my advice is to clean up that logic and then tackle the code inside the loop, which also has problems

>>57061115
Oh, that's another issue. You probably want to move your writes outside the for loop

>>57061147
>>57061158
The exercise states that you have to use .read(1) to read the file character by character to see if you last character is the same as the one its reading to know if it has to be changed.

In C++, is there a better I can find the type of a derived class from a pointer to a base class?

Right now I have something like this:

 
class A 
{
    int id=A;
    enum derived 
    {
        A,
        B, 
        C
    };
}; 

class B : public A 
{
    B()
    { 
        id=B;
    }
};

class C : public A 
{
    C()
    { 
        id=C;
    }
};

A *object = new B; 

switch(object->id)
{
    case A::A:
        break; 
    case A::B: 
        B *poop=dynamic_cast<B*>(object);
        break;
    case A::C:
        C *poop=dynamic_cast<C*>(object);
        break;
}

Use a union. The way you're doing it right now could create alignment problems.

For a class, I am building an iPhone application using Swift to make a native version of a voting/polling web application that another part of my group is making.

Essentially, we have a /log_in, and a dynamic /quiz page. I've never done this kind of stuff in Swift, so I was wondering what kind of stuff I'd need to google/research to learn how to essentially strip the question text, the answers text, and generate a native version. Would it be something related to UIWebView? Or would it be easier to just try and make it 100% native?

TL;DR, need to build iOS native application that essentially strips text from a web page, and sends back user selected answers back to web page. How do

>>57061508
Writing to one member of an union and reading from an other member is undefined behavior.

I'm having trouble with recursion. Are there any good resources to learn recursion out there?

Program opisafaggot;
Uses wincrt;
Var op:string ;
Begin
Op:='faggot';
Write('op is a', op);
End.

Friendly reminder that you can interpret lambda calculus in the internal logic of any topos.

how do I do this in C

nopp jk | jk == "jk" || jk == "kj" = False
nopp hl | hl == "hl" || hl == "lh" = False
nopp _ = True

is there a catch all semantic like _

>>57061569

"default"

>>57061569
Pattern matching?

I'd guess you'd use if/else or switch, depending on what you want to match.

I don't get this mentality.

I'd rather write programs in a fun language than in an tedious and/or ugly language.

That said, I'd still learn to read c++ code.

>>57061250
okay, i was mad enough to go check this
a buffer like this is always fixed at some point. if you open up a file that says "ree" and you read() in a character, then that "r" is no longer visible in the buffer. so, for example, i don't think that character being read at the bottom of the loop is ever going to be seen by the rest of your program

so if you absolutely must use .read() then get rid of all the for loops. at the start of whatever loop that results you want to know the last character and how many times in a row you've seen it. test the simplest examples first. even the last one you gave was too much

>>57061807
>Figured it'd look good on a resume.

That makes sense. But still, I wouldn't want to work with something I consider ugly (just my opinion).

Same reason I wouldn't a job as a java programmer, even though I'm plenty capable of programming in java.

Hey /dpt/, I'm doing a programming assignment for a class at university and I'm really struggling.

This is because the assignment has to be written in SWI Prolog. I understand resolution and clauses etc. But I don't understand how to put things together to make a program. I guess I want to know how to write primitive clauses that don't call other clauses to operate.

Is anyone here familiar with Prolog?

Yes, in general. If you don't know what you don't know, you may be tricked into thinking that you know nearly everything there is to know. The more you learn, the more you realize how much there is that you DON'T know.

We're doing it with constructors, doing multiple external class files, and 2D Arrays. I'm sure you could do it more simply but I assume it's just to get us into those concepts. I have no reference as to how fast/slow that is, I was an art major at community college before getting my shit together and doing CS. but we're working on inheritance, image rendering, and we did array lists.

I mean, a bit chubby it's ok, I prefer a girl who's a bit fatty rather than a spooky skelly stick.

I need a guide on making a basic dropdown menu be able to set a variable using Javascript. For example, you select "Three" from the dropdown list and it makes the number variable equal "3" behind the scenes.

W3 schools didn't have anything about it that I saw and searching kept turning up using dropdown menus to navigate between pages (not what I want).

> What I have so far

Difficulty: <select name=diffselect onchange="diffSet()">
<option id="0">Beginner</option>
<option id="1">Basic</option>
<option id="2">Standard</option>
<option id="3">Expert</option>
<option id="4">Challenge</option>
</select>
<div id="yep"></div><p>

> The JS currently is just a testing block.

function diffSet() {
   document.getElementById("yep").innerHTML = "It worked";
}

>>57064254
There's a difference between "fat" and fucking enormous.

The socially acceptable definition of fat doesn't go above the obesity line.

The password part of the name after the # gets chopped, passed through crypt(3) and it becomes your tripcode.

add an attribute, value hidden or make your own data type, and then get it with getattribute() or use a jquery library that provides more flexibility

<option id="0" value="gedgud">Beginner</option>

var val = document.getElementById("0").getAttribute("value");

That's why I was looking for links to a guide or two. Maybe I put the wrong search term in or something, but I couldn't find it when I know there should be tons.

Thanks for the code, even though it didn't seem to work. It kept returning "0" on all options.

That seems awfully specific, don't you think?
Scanning through a file to find magic numbers for other file-types doesn't seem difficult.

>>57064626
Even 4chan has problems with that. I doubt there's an easy solution. Even if you fix it there are illegal text strings... Making anything that allows people to upload arbitrary things is a huge annoyance because you have to constantly monitor it and deal with lawyers.

>>57064642
You'd be surprised on both accounts. There's a nodejs library to left-pad strings and it took down the whole internet one time... Also cleaning arbitrary data is exceedingly difficult. You can't blacklist stuff, you can't whitelist stuff... Best you could do is scan for signatures as you say but that's easily defeated by any attacker.

Look at what data container/structure you're using and how your using it, most containers have specific pro's and con's in relationship to their use and efficiency so look at what you need then look at what's available (array's, vector's, map's/hash's etc).

To actually git gud you need know that and see just how shit performs, so use something like Valgrind and setup some timers and literally test each chunk you're worried about and make changes to see what works best.

well, being honest about why I got fired seems like a bad move considering I got fired for being a dickhead, but if I remove the job I have a huge gap and lose some of my best experience

Probably because you will have no idea what kind of hardware the tools are going to spit out at the end.
Multipliers and dividers require a fuckload of hardware if you want to do it quickly.

>>57068082
Why does that matter if the synthesizer takes care of it and not us?

>>57068090
I'm really not claiming to be a hardware expert, and all I've really done is a single university course which covers this sort of shit (up to multipliers, it didn't cover dividers).
However, with something that can blow up in terms of hardware, like a multiplier or adder, you probably want to have some control of the characteristics of it. You could take the much smaller option in terms of gates, but is multi-cycle (log2(divisor) cycles), or the much larger option which requires a fuckload of gates but can get it done in 1 cycle, or whatever else you might do.
In terms of simulation though, it's not important.
