You don't learn that in theory classes moron. You experience and learn from that in project based classes.

> The vast majority of modules should include decent-sized projects
Wow. Anon you should really start your own university since every university disagrees with your shit opinion. There is no point in practical uses if you aren't sure that practical use is going to be relevant after your degree. Theory based knowledge last for a lifetime while practical based knowledge for a specific language doesn't.

Still working on this bubble sort meme.

    void bubbleSort(int arr[][8], int size)
{
        bool sorted = false;

        for (int i = 0; (i < size) && !sorted; i++)
            for (int j = 0; j < (size - i - 1); j++)
                if (arr[j][7] > arr[j + 1][7])
                    swap(arr[j][7], arr[j + 1][7]);
                else
                    sorted = true;
}

I'm trying to sort rows of a two-dimensional int array by descending value order of a single column, arr[][7]

I feel like a big dumb cuck, here.

>>59378057
I'd stick to VIM. All emacs has going for it is that it uses lisp for it's configuration. This enables far more powerful plugins that are easier to implement, because it uses an arguably real language compared to vimscript, which is a nightmare, but actually editing text blows dick, especially compared to VIM. There's just no comparison to VIM's modal editing. Emacs can emulate vi's bindings, but the power of vi extends far beyond it's bindings.

I spent five hours setting up a build system with CMake, and by the end I was kind of enjoying it. Was success just fucking with me, or am I actually sick?

Why do we have config files for programs? Shouldn't they be considered harmful?

Why not a referentially transparent approach where everything is available as a command-line parameter, and users can save "settings" through shell aliases?

Then we wouldn't have to juggle any hidden files. Everything would be in your .shell_config

Honestly, that's fucking stupid desu. "Let's take all of the cleanly seperated easily findable files and just fucking stick them into a single gigantic abomination of a shell config!"
Not to mention how you would maintain something like that. And what if a program had something special about its config? Would two systems have to exist side-by-side?

>>59378307
You'd better ban pajeets, they're disgusting.

>>59378311
You sound like a brainlet desu

/program-name

in vim. bam instant access to "settings"

Much better than having to worry about the program's state being modified in some other file, + introducing the mess of config file defaults and hierarchies

Want setting X? Call

program --x

. It makes perfect sense.

Anyway it doesn't matter what you think. I already write all my own software to be configless in this manner. Once other people realize how good it is, I think it will eventually catch on

>>59378387
Now what if a program that isn't your shell wants to call another program?
How would sensitive information like passwords be handled?

>>59378408
Neither of those are actual arguments

>>59378425
Why the hell not?
Programs calling other programs is an extremely common thing to do.
So that means that the programs now need to have access to your "shell aliases"/"global config" file, and within that file, it then has access to everything about every other program, including passwords.
Now how about setuid programs? Does it even get to have access to files that only root is supposed to have access to?

>>59378387

It has a high learning curve.
It is immensely useful once you have gotten over it.

Vim is easier to start with but doesn't have as much stuff it can do for you. On the other hand, it isn't meant to. It shells out to other program. Emacs integrates them.

Which you prefer is a matter of your personality.

Notepad++ and its ilk are all in the utter plebeian tier.

I like Lisp as a language, but I fear it's a meme language that cannot have anything productive done in it. Please prove me wrong.

>>59378175
And? Emacs can edit files over SSH. (It integrates your standard openssh client and talks to the other computer using that.) So it doesn't need to be installed on other systems.

Why bloat your servers with unnecessary stuff?
(also, ed is the STANDARD editor.)

We only do the highest quality fizzbuzz implementations on /g/.

"Useful" is for faggots.

>>59378603
It's not a "meme" language since no language can possibly be a "meme". Lisp is fucking garbage though. That's not to say that you can't "have something productive done in it".

I don't mean to say it's impossible - it just seems impractical. When I asked someone about GUI libraries, I shit you not, they recommended I write a fucking web server to be hosted locally and just do the UI in HTML and CSS. Sure, you can use macros to convert S-Expressions into HTML easily, but Lisp doesn't even have something like Electron to make it one seamless application making it APPEAR to not be a dodgy hack.

A programming language with no I/O.

>>59378829
It's pretty useful actually.

>>59378845
No. Kill yourself, you literal autist.

>>59378845
It has about 0.000000000000000000000000000...1% the usefulness of Haskell, which in turn has 0.000000000000000000000000000...1% the usefulness of a proper programming language.
And even the former statement is probably way overestimated. I'd say that a programming language with no I/O actually has 0 uses, because whatever you do in that language is equivalent to doing nothing in terms of effects, which is the only thing that matters, effects.

>inb4 it's useful because I can compute stuff!
Computing stuff is only useful if you output the result.
If you compute something and do nothing with the result, then it was a useless computation and a waste of resources.

>>59378680
But C do have objects, in the form of compilation units (source including all headers and with all macros expanded). What it doesn't have are classes.

Yes, according to your subjective judgement. But I'm not your friend or your family, I couldn't care less.
>I'd say that a programming language with no I/O actually has 0 uses
This is blatantly false and even you know it as you have demonstrated in your first sentence.
>which is the only thing that matters, effects.
You can have all the effects you want. It can literally be assembly-level if you wish.
>Computing stuff is only useful if you output the result.
So computing "1 + 1" written on a piece of paper is only useful if you write "2" on the same paper? What sort of retardation is this?
>If you compute something and do nothing with the result
The result is passed to something else which accepts the resulting type.

>>59378935

All programming languages that are Turing complete has the ability to use system functions and output something. Whether or not it requires you to break the stack

Basic Question, but what's the easiest way to put 2 numbers between brackets (I.E. [3,2] ) Into their own variables in C++?
I can't figure out for the life of me how to do it.

>>59378975
The ability? Definitely. But I/O isn't a requirement for Turing completeness. If you think it is, then your education has failed you.

>>59378977

>>59378964
>So computing "1 + 1" written on a piece of paper is only useful if you write "2" on the same paper? What sort of retardation is this?
If the whole point of your program was to compute 1 + 1 then yes, not outputting the result would be a waste of computation. Why did you compute it?

>The result is passed to something else which accepts the resulting type.
Yes, and then at the end of your big chain of computations, you output a result in some form.
A language with no I/O will perform all those computations and never output any kind of result at the end of it.
That is by definition a useless computation that is the equivalent of doing nothing.

>>59378975
That's not an I/Oless language then.

What good is an effect if you can't observe them? You can imagine your happy little programming world all you want, but it's completely useless if you can't see inside.
>So computing "1 + 1" written on a piece of paper is only useful if you write "2" on the same paper?
At some point, it's going to have to be evaluated and output somewhere.
Do you even intend for a computer to actually execute your stupid language?
>The result is passed to something else which accepts the resulting type.
Does that have I/O?
If it doesn't, it's equally as useless.

>>59378990
>But I/O isn't a requirement for Turing completeness
Being able to see what's on the tape afterwards is the only thing which makes a turing machine even remotely useful.

>>59379031
You stupid fucking wetback nigger. By system functions I meant the underlying functions that programs use to read/write text. So all Turing complete languages can just scroll over to those functions and run. Therefore they all have input/output

>>59379026
no, you just need a few GB of RAM

>>59377924
First, you got the algorithm wrong. As you wrote it, it stops whenever two consecutive elements are in order. You have to consider the column as sorted at the beginning of each turn and consider it unsorted as soon as two elements are swapped.

Second, your swap function only swap the elements of the column, not the entire rows themselves (if that's what you want).

>Why did you compute it?
To compute the value and use it later.

>Yes, and then at the end of your big chain of computations, you output a result in some form.
So? You can have a "halt" function which accepts the last thing passed in a sequence and terminates the program.
>A language with no I/O will perform all those computations and never output any kind of result at the end of it.
Correct. Your point being?
>That is by definition a useless computation that is the equivalent of doing nothing.
No. A useless thing is by definition something which has no use. Being passed as an argument to a function is a use, therefore it isn't a useless computation.

You technically can observe them in some sense. The OS does I/O so you can see the resource usage go up.
>At some point, it's going to have to be evaluated and output somewhere.
Evaluated? Yes. Output? Nope.
>Do you even intend for a computer to actually execute your stupid language?
Yes, I'll be using LLVM to generate machine code. Although I've heard it reduces non-IO programs to single ret instruction so I will have to deal with that somehow.
>Does that have I/O?
Nope. I/O is simply isn't a thing in my language.
>Being able to see what's on the tape afterwards is the only thing which makes a turing machine even remotely useful.
You have shown yourself to be retarded beyond any reasonable doubt. If you think being able to look ahead is somehow "I/O" then I can only feel sorry for you.

>>59379067

>>59379035

>If it doesn't, it's equally as useless.
No language is objectively useless. For you that might be the case, but please specify this kind of bullshit with "useless for me".

>>59379063
I changed it to this.

void bubbleSort(int arr[][8], int size)
{
    bool sorted = false;
    for (int i = 0; (i < size) && !sorted; i++)
        for (int j = 0; j < (size - i - 1); j++)
            if (arr[j][7] > arr[j + 1][7])
                for (int k = 0; k < 8; k++)
                {
                    swap(arr[j][k], arr[j + 1][k]);
                    sorted = false;
                }
            else
                sorted = true;
}

Now it will actually sort, but in ascending order instead of descending order.
Tried changing

if (arr[j][7] > arr[j + 1][7])

to

if (arr[j][7] < arr[j + 1][7])

But that just broke it.

The fact that you set sorted to true when two consecutive elements are in order means that if the two last elements are in order, you consider your array sorted, even if the previous elements may still be not sorted.

Who the fuck mentioned lookahead?
There are many ways to define a Turing Machine, but the way I learned it, a Turing Machines input is what's on the tape in the beginning, and the output is what's on the tape when the machine has terminated the head is parked.
Your Turing Machine would start with a blank tape, and finish with a blank tape, which is completely useless. You would see if it halts or not, but that's undecidable.

>And therefore, the computation was useless.
See the line above. You really should learn to differentiate between the objective meaning of "useful" and your preferences.
>Uh no. You discard the value.
Only at the end. Everything else is technically a bunch of functions calling other functions.
>Why does it accept a parameter if it doesn't do anything with the parameter?
Because it's a function. A function is by definition something which takes arguments.
>The whole program is useless and does nothing.
See the second sentence.
>Such as an I/Oless programming language.
So in your warped mind something can have a use and still be useless? You easily make it into the top 5 most retarded people I've talked to here, and that's quite an achievement.
>Only if it gets used*
Using something is a use. This is obviously true.
Therefore using something as an argument to a function is also a use. Meaning that it isn't useless.
>It is if the function does nothing with the parameter.

But this would be false. Unless he adds a "for me" here this sentence is blatantly false provided you believe "something which has a use is useful" to be a true statement, which any non-mentally ill person should.

I never said otherwise. I'm fully aware that lambda calculus is an equivalent type of computation.
By having no "I/O", that means that your lambda calculus expression has no "arguments" and evaluates to nothing. Again: completely useless. I don't even think you can write such an expression.

Using the CPU and not using the CPU for the sake of using/not using the CPU and nothing else has no use.
Hence why decent compilers transform those kinds of programs into equivalent programs that use no CPU since it's the same program but lighter on resources.

If your compiler optimized something out, it means that code was useless and redundant.
This is proven by the fact that the program, when run, still achieves the same thing. Just like how an I/Oless program when optimized still achieves the same thing with lighter resource use: nothing.

Not so obvious it seems. In the giant scheme of the universe, your statement stands true. But in the context of your program state, not so much. If it is independent of timing, the program don't care about whether CPU is used or not, the CPU can be abstracted from computation.

Also, talking about lack of I/O, I'll state something even more inane: if a sign has no use, it has no meaning. But that doesn't mean you can't give meaning to a sign a posteriori, yet it may be a clue about the redundancy of your sign.

It doesn't matter if you use the CPU or not. That's just a minor detail.
What matters is if the program does something useful, which a non I/O language by definition cannot possibly do anything useful.

For you. It doesn't somehow negate the possibility of it being useful.

>>59379634
It is. It shows that you can think about functions in a lot of different ways. Someone who has been crippled by I/O will obviously tend to think in terms of it. This doesn't somehow mean that the non-retarded ones have to do the same.

Actually, you don't. How can I tell? Because you're not interested in the result. Therefore you're not interested in computing anything.
Because the sole purpose of computing something is looking at the result. There is just simply no other use for computing something no matter how you look at it.

>For you
Not just for me. It is objectively useless. There's no subjectivity anywhere here.
It is useless for you and for me. It's just that you, you retard, don't yet realize that it's useless for you.

"2 + 2" is a valid expression in language x.
'compile' is a function which maps valid source code of language x to a program.

>>59379926
The difference is that your source code that you want to compile has to be hardcoded into the compiler itself, and the output program is not even outputted, which means if you want to run your outputted program, you then have to implement a virtual machine in your compiler if you want to avoid I/O.

The problem is that because your source code is hard coded, you have to recompile your compiler every single time you write a program. Which means you'll never ever be able to ditch your first compiler.

Usually what sane programmers do is they compile the compiler once and keep the compiled program around on disk and call it (which does I/O) to compile further programs.

>>59380913
sed and awk are excellent tools for manipulating text in shell scripts.
You're doing yourself a disservice by not knowing them.

>>59381086
why not just use python or perl?

>>59381098
Because awk and sed are more useful for the things they're good at: one liners and shell scripts. They aren't for making "proper" programs.
I've written many bash scripts, most of which are just gluing calls to sed, awk, grep, curl, and a few other more obscure utilities (like jq) together, and they get the job done very concisely.

>not knowing how to traverse a LinkedList
You must be a newbie to programming, I'm guessing.

Depends on if your list is singly or doubly linked. If your list is singly linked, start at the head. For as long as you're not at a null node, loop over the following:
>test the data in the node you're at against the value you're searching for
>if they match, return the value
>else, move on to the next node

If your list is doubly linked, the procedure should be basically the same, except you can optionally start at the tail node instead. Frankly, if your list is doubly linked, you can start anywhere. This benefits the efficiency of the search algorithm if you have a node pointer static to the function, instead of instantiated each time the function is called, and you just leave it where you found the last value and pick it back up wherever you left it--since, in the case of a sequential data structure like that, new requests are likely to be for values close to the previous requests.

>>59381419
>binary except your 0 key is broken
just use alt + 48 instead
or the literal hundreds of other workarounds for this

>>59381449
that's not a proper test since you're loading a whole language interpreter (that takes a little bit of time)

just check out tests where perl shows weaknesses but it's not regex speed

I don't know what language you're using or what your LinkedList declaration looks like, but let's suppose you're in C and you have code that looks like this:

struct LinkedList {
   int first;
   struct LinkedList* rest;
};

Then here's how you would do the loop:

struct LinkedList* LinkedList_Search(int value, LinkedList* list) {
   for (; list; list = list->rest) if (list->first == value) return list;
   return (void*)0;
}

The result of (list) in Lisp is an empty list. That's not at all comparable to what my snippet does.

A more accurate Lisp equivalent would be as follows:

(defun linkedlist-search (value list-var)
   (cond
      [(not list-var) nil]
      [(eq value (car list-var))]
      [1 (linkedlist-search value (cdr list-var))]))

>>59377805
>What are you working on /g/?
An operating system without I/O.

To prevent nitpicking, I/O shall be defined in this context as:
* peripherals like keyboards, mice, printers
* networking
* graphics, sound
* anything a human user could read or manipulate

God says:
* preemptive scheduling
* scheduler maintains an idle process that uses 100% CPU to prevent programmers from using CPU temperature as a form of I/O (you could drip liquid nitrogen on the CPU to input data, or output data by heating it)
* 1920x1080 VESA graphics (filled with a single color that never changes)
* peripheral I/O ports emit pseudo-random noise all the time (this require real-time functionality in the kernel to prevent side-channel attacks)

The language is still undecided. It should be something like Coq, that can be proven formally, because there is no way to debug or even test programs.

q.

So I need to calculate some 3D histograms in Python and I'm wondering if I can use OpenCV's calcHist() function for that. Allow me to explain.

In 1D, things are simple. Say I have an image img, I can calculate the histogram of, say, the first channel:

cv2.calcHist([img], [0], None, [64], [0, 256]

where 0 is the channel index, None could be replaced with a binary mask if I only want the histogram inside a certain area, 64 is the number of bins and [0, 256] is the range of values to include in the histogram. I can then plot this as "element count over value of channel 0". Symbolically speaking, the histogram might look like this:

value count
    0     0
    1     0
    2     0
...
   10     3
   11    20
   12    23
...
  253    10
  254   112
  255    90

Now I want a histogram with four axes, one of which is again the element count, and three of which are for the values of one channel each. The Histogram would be something like:

[  0,   0,   0]   0
[  0,   0,   1]   2
[  0,   0,   2]   1
...
[  0,   0, 254] 12
[  0,   0, 255] 2
[  0,   1,   0]   3
[  0,   1,   1]   2

and so on. Basically a histogram which keeps count of full colors, not just individual channel values.

I could write that in "vanilla" Python but it'd be slow as shit, hence me wondering whether I can adapt cv2.calcHist() to this. Simply passing a tuple of ints for the channel indices or an array of channel indices does not work:

cv2.calcHist([img], [0, 1, 2], None, [64], [0, 256])
cv2.calcHist([img], [(0, 1, 2)], None, [64], [0, 256])

(samefag) Crud that's wrong. Correction:

(defun linkedlist-search (value list-var)
   (cond
      [(not list-var) nil]
      [(eq value (car list-var)) list-var]
      [1 (linkedlist-search value (cdr list-var))]))
