i'm not a homo but i was going to say "no because i'm a homo" for keks
i then realized
do you think when homos are forced into straightish situations they have the same feelings about it as straights do when the situation turns too gay
like
"ew that's fucking gay"
except they're the homo instead
so it's like
"ew that's fucking straight"
like
hot girl showing too much tit

Here's my kode from another thread. Guess what it does.

procedure convert(n, r)
    res := 0
    reverse(n) ? while res +:= r ^ (&pos - 1) * move(1)
    return res
end

It looks like the only thing you need is something in download_files() to raise an exception upon a cancel event.

How do you guys handle switching back and forth between languages? I occasionally move between python, lua, javascript and c#

for example, in some languages a boolean statement is 'True', while in others it's 'true'.

Some doesn't use semicolons to end statements. Some use :, or 'then', etc.

Do you just spend 10 minutes refreshing on basic syntax? its pretty annoying

>>62189366
Gonna try to find other solution. I don't want to make my downloader dependent on GUI or thread class. But I'm going to take your suggestion into account I don't find other solution. Thank you.

>>62189410
I do it by not having sub-average intelligence

>>62189410
There are languages with syntax derived from C and languages with syntax derived from BASIC. Everything else is weird shit you won't be using very often anyway (don't even mention lisp meme). Most simple mistakes are automatically fixed by good IDEs anyway.

>>62189444
I expected a bait response but i suppose I was wrong for having a little faith in some /g/tard.

I have set of letters and numbers. I need to exit this loop when it encounters a number.

do {
            scanf(" %c", &record);
            printf("%c", record);
        } while (record == 'H' || record == 'O' || record == 'w' || record == 'S' || record == 'P');

I feel like I tried putting everything in while condition but this loop just prints everything, even numbers and then stuck printing last letter.

>>62189519
It's not a bait response.
Most languages are fundamentally the same, their only difference is cosmetic.
If you actually get thrown off by the fact that some languages force semicolons and others don't it means you memorized a language and not how to program.

>>62189531

do {
            scanf("%c", &record);
            printf("%c", record);
} while (!isdigit(record));

Something like this should work just fine. isdigit() is in ctype.h iirc.

>>62189509
>Everything else is weird shit you won't be using very often anyway
The problem is when I actually do need to use it for something simple

>Most simple mistakes are automatically fixed by good IDEs anyway.
True, but I usually only have my IDE set to the main language I'm using C#.

I use notepad++ for everything else. I should proper get a proper IDE for them.

thanks for the non-bait reponse

it's easy to write an interpreter for such a notation AND to compile it
so it's useful to understand not just for lisp

(print_num (fibs_iter 10)))


@(function fibs (n) () 
(if (< n 2) 
    n 
    (+ (fibs (- n 1)) (fibs (- n 2)))))

SO BASICALLY THERE IS NO WAY TO GRACEFULLY AND EASILY CANCEL DOWNLOAD IN FUCKING PYTHON
GOOD JOB GUIDO VAN ROSSUM

are all languages retarded like this? or is it just python?

>>62189867
use curl

>>62189867
see this is what happens when everyone relies on hobbyist modules and nobody wants to write any new code or at least some bindings for curl.

>>62189867
we warned you about python anon

reminder that guido wanted to remove lambdas from python

>>62189867
im sure it's your code's fault
what, you cant end a thread using an if branch inside the execution of the thread itself

thread runs a function
inside function
if bad shit is happening:
.....return

lol

>>62189867
I thought you were gonna try checking for bCancelDownload?
Why wouldn't this work?

>>62189867
we told you not to do multithreading in python bro

>>62189867
ok, instead of launching a thread
launch a brand new process
that process can be anything you want
for example a bash script that downloads the file with curl or another python script that downloads the file
if you want to cancel, just kill the entire second process
now you have true multithreading with python

>>62189962
I tried. But thread MUST complete its task before it yields control to main thread, or joins with it. I could go as another anon suggested putting an 'if' statement in my download_files() function for cancel signal, but that would make my code spaggeti.

>>62189867
There are several ways you can accomplish this.
That guy alone listed several possibilities.

>>62190090
>just add an if branch inside the thread
he doesn't want to do that for some reason

>>62190090
the magic "if statement" solution doesnt work. the downloading thread is blocked waiting for the download to finish. there's no place for an if statement.

Give me a fucking break you insufferable autist. Spinning off a separate process for his download is perfectly fine.

>>62190264
>in the amount of time it takes to get involved you could have just made something yourself.
What does that even mean?

>>62190230
I have. But as I said, it would make Downloader class dependend on GUI. But I guess I could instantiate it with self.downloading = True, and if the cancel button is pressed that it could set self.downloading = False (and then raise an exception as another anon suggested). But, I'd have to pass an instance of Downaloder class to both thread and the cancel button. You may be right, it doesn't sound like much of a spagetti code after all.

>>62190285

I'm learning C as my first real attempt at programming, and I was wondering if someone could point me in the right direction on a project that I am working on.

I ended up copying it because I didn't know enough, but I want to do it for real this time. Here's the issue:

I want to initialize three doors, one has a car, the other two have goats. They need to be random, but always one car and two goats. Does anyone have any ways I could go about making this in C? I haven't finished my first C book yet, so I'm sorry if this just pissed you off.

Actual gay man here. I do this. And my reasoning is because using "gay" in such a way usually is a replacement for the words stupid or retarded.
It's offensive. I don't go on a rage though like some SJW. I just replace Gay with Straight as kind of a "fuck you. I can do it too. How does that feel" kind of thing.
Completely passive aggressive, but it usually gets the point across.
Being gay is not a negative thing to be shamed for.

We can. There's just a lot more red tape involved and a lot more cost. No gay couple has an "oops" child. Every child a gay couple has, whether biological or not because red tape, is wanted. Look up surrogate mothers.

Yep with some Perl interspersed. It flattens out a C-style function that's been manually wrapped like so:

It can be made slightly more readable by moving the second expression into a subroutine but that's much to boring.

I'm new if you can't tell by my question, and I'm getting started with python. Anyway, why can you append integers but not extend lists with them? I'm trying to get results to go into a list and if I append, it works but it prints a bunch of lists ([1] , then [1, 2] , then [1,2,3] etc).
I want to add them all in one go and the notation where you define the list as list = [x for x in...] is not working, for some reason.

>>62192727

Thank you guys. Does the author of the book phrase it that way, because in a way, you are "expanding the number" of characters used? For example, 1 tab, into 8 spaces?

Yeah. What ever amount of spaces a tab character represents.

>>62192783

Because the definition of a tab is completely up to the editor and user configuration. If you want consistent indentation, use spaces.

Brainlet here, going through K&R. I am having difficulties understanding this program. Here is the assignment

Exercise 1-22
Write a program to "fold" long input lines into two or more shorter lines after
the last nonblank character that occurs before then-th column of input. Make
sure your program does something intelligent with very long lines, and if there
are no blanks or tabs before the specified column. 

What exactly does the author mean by "folding"? Where should I "fold"? Also, I was reviewing the answer, and I didn't really understand it as well. I would like to post it, but for some reason I am getting a "connection error". Any way to bypass that?

>>62193508
It means that if a line exceeds a certain length (column) you find the next whitespace and split the line so that the other half is on the next line. e.g.

the is my long line

After using the program on it you get

this is my
long line

>>62193629
>>62193508
>you find the next whitespace
Change that to the white space before the n-th column

What do you call the operation where you generate all length combinations of a multiset (list)?

Say you have the multiset (or list): [1, 2, 3, 4]
I would generate:
[1]
[2]
[3]
[1, 2]
[1, 3]
[1, 4]
[2, 3]
...
[1, 3, 4]
[2, 3, 4]
[1, 2, 3, 4]

What would that operation be called?

It is essentially picking the first partition of all the 2-partitions of the multiset (or list).

I hit a brick wall with my C program. Any experts here that could help?

Basically I have an array of a strings

char *filenames[] = { "aaaa", "bb", "ccccc" };

I want this to be part of a struct. Because the number of strings inside the array can vary, I can't just define a fixed size array in the struct. So I tried a pointer to it.

struct load_data {
    char **img;
};
const char **ptr_images = filenames;
struct load_data data = { ptr_images } 

this gives me these errors and warnings:

warning: initialization from incompatible pointer type [-Wincompatible-pointer-types] char **ptr_images = filenames;
note: (near initialization for ‘data.img’)

can anyone tell me the glaring error I'm making and what the right apporach would look like?

which means its a pointer to a space in ur code which cant be edited.
if u memcpy it then it stops being a const ptr and becomes a regular piece of memory u can edit.

flexible arrays bring on their own set of rules u need to learn before using. specifically how to alloc, access and declare.
