Goddammit I'm sick of all these fucking segfaults, and gdb's completely useless tracebacks.
Why is this code breaking?int sendString()
{
malloc(100);
char *s;
printf("enter string to send: ");
unsigned buflen;
scanf("%s%n",s,&buflen);
char fs[buflen + 20];
strcat(fs,"./haskell_string ");
strcat(fs,s);
system(fs);
return 0;
}
As you can see I've applied a lot of duct tape to this code but it still segfaults.
Right now it's segfaulting on the strcat but I can't seem to write this in any way to have it actually work. I tried snprintf and that didn't segfault, but it didn't actually do anything either (it was just appending null characters to the string).

-Takes all the command line arguments passed to the program and turns them into a single string
-if the resulting string is empty, it then takes a line of input from the user and sends it as the command line argument to the 'string' program located in the executable's directory
I'm setting it up right now so there's two programs written in two different languages that do the same thing: print a string if given one, and send a string to the other program if not.

Whitespace is syntactic sugar in Haskell, just like Lua.
In fact the compiler gets rid of the indentation itself. You can manually write without relevant whitespace if you really want to:main = do {
args <- fmap unwords getArgs;
case args of [
_ -> do {
putStrLn("Enter string to send: ");
s <- getLine;
let fs = printf("./string %s",s);
callCommand(fs);
}
]
}
>>52492161

Actually for Sepples it's deeper than that. The '}' is arguably the single most important language construct, because in C++ it affords you deterministic resource management.

I'm pretty sure can you directly pipe it, like:main = do

true : (. But that's honestly my favourite thing about F#. You can still write nice code that even normies can read and find appealing.
I'm also hesitant to use functional composition like that because it makes my functions much less flexible. I'll often find I want to add an extra argument later or some shit and need to unwind all the composition stuff.
Sometimes it's sexy as fuck though

But I did read a study years ago that suggested that men and women ranked much more equally in college for classes in learning haskell, compared to learn C or Java.

Java is the second language I'm learning and I hate it already.
>>52492862
I know lots of programming languages, and I like Java. It's not my favorite language, but it's very useful.
It's faster than a scripting language, everything you do is very explicit and readable, and it has a large ecosystem so you can usually import a library to solve your problems. It also ports to most platforms very easily.
>>52492862
>Everyone hates Java
Talk for yourself.
>>52492923
And yet you have stuff like C# that is superior in every way. To know C# is to hate Java. I don't think i've ever met someone who knows both pretty well and prefers Java.
Well I've duct-taped my way back to the start, and I still can't fix these damned segfaults.int sendString()
{
char *s;
printf("Enter sstring to send: ");
scanf("%s",s);
char *fs;
sprintf(fs,"./string %s",s);
system(fs);
return 0;
}

Antagonizing people is basically the best way to get information from them.
>>52492973
I would but most of the Java code I've written is proprietary.
Java code is very readable in my opinion because the language's entire philosophy seems to be safety and explicitness. A line of code will be verbose instead of cryptic and short, and it's hard to write code that does something other than what it says it will do. There's not much ambiguity in the language.

Hey /dpt/, how do I find the entry point of a large open-source program? i.e. the source that includes all the other files and has the main function?
>>52493333
post script my nigga
>>52494021
Use YIN
>>52494019
oh that would be simpler then, rather than using random values, I check the relative y position of the paddle and ball if a collision occurs. At a paddle length of 4, I can store the possibilities in 2 bits. But yeah, pong is still too simple for my tastes
>>52493648
>>52494028
just grep int main
>>52494028
main.cpp
>>52494021
fourier transforms
>>52493907
post code. the answer is either pattern matching or to not do what you're doing.
>>52494060
those look like scary words
and the graphs on the wiki page look even scarier
https://en.wikipedia.org/wiki/Fourier_transform
can you explain it like i'm a retard?
>>52494084
before FT: graph is how the sound looks - how to move the speakers (how computer perceives it)
after FT: graph is pitch on x axis vs loudness (how humans perceive it)

It's part of my program's argument parsing. Basically I want to do `some block of code` if there are arguments, and `other block of code` if there aren't.
I figured the easiest way to do it would be to case the args itself with Nothing and _, but that doesn't work.import System.Process
import System.Environment
import Text.Printf
main :: IO()
sendString :: IO()
writeString :: String -> IO()
sendString = do
print "Enter string to send: "
s <- getLine
let fs = printf "./c_string %s" s
callCommand fs
writeString str = do
print str
main = do
--args <- fmap unwords getArgs
case getArgs of
Nothing -> do sendString
_ -> do
args <- fmap unwords getArgs
writeString args
This code obviously fails.
>>52494084
this probably isn't a good explanation for a retard, and i'm no expert here so i might be wrong, but
the simplest form of a sound wave is a sine wave (pic related). this is formed by the function y = sin(x). hopefully you learned about this function in high school at some point. this can be altered to have higher pitch or whatever by doing things such as y = 2 + sin(x).
sound waves in nature are not always this simple, however. they are formed by many sine waves combining, forming a very complex function that you can't really derive pitch from. fourier transforms basically transform the complex sound wave into its sine wave constituents, allowing you to determine things such as pitch.
>>52494202
are you sure that _ isn't "any value"
try ""
>>52494227
_ is 'any value', but the problem is that (im pretty sure) getArgs wouldn't return anything if there's no args. I'll try "" though.
>>52494202
It's not as simple as that.getArgsreturns a list of byte strings -- you'll have to check against its length and usemaybeReadand so on.
>>52494249
>>52494227
Well shit, that worked!
Thanks anon!

What are you drinking and listening to while programming?

someone who knows more about crypto than me, should i use sha1 or md5 for checksums (or something else entirely?)
>>52494470
md5 is awful, use sha-2

We're sorry Orange Prince
It's the damn scots
>>52494469
Bloody scots
>>52494463
That wont compile because getArgs :: IO [String] . getArgs is a computation that does IO and then returns a string. We need to be talking to the argument string itself. Using <- tells the compiler to sequence the actions, saying "when getArgs is done, do this case statement on the result."

two programs do the same thing
one in haskell, one in c
C source code length: 573 bytes
Haskell source code length: 302 bytes
C binary length: 7872 bytes (7.8KB)
Haskell binary length: 1546712 bytes (1.5MB)
damn do I love haskell, but it really is a meme

Choose one.

Resident cypherpunk here. Neither. Or this >>52494479 anymore because of length-extension and because we have better things now anyway.
You should use BLAKE2b. It's more secure than both of those and SHA-2, and faster than all of them.

There's a convenient fast implementation in libsodium, or on the official site. https://blake2.net/

I assume I should be using udp for connections?
How do I handle handshake/login? Roll my own half-assed stateful connection from udp? How do common firewalls/NAT handle client-initiated udp connections?

i'd use it, but most distros don't even have a package for it yet so using it over something else (right now) would force people to manually compile it and shit. if i ever make a distro with this package manager then i'll include blake2 though

Always share actual text instead of images.
int rightNumber = 42; Assign when you declare, if possible
Check your braces, for the love of god.
>>52494858
While loop is more idiomatic than do-while, prefer it.
Avoid continue if possible.
You increment a twice, avoid code duplication.while (a < 20) {
if (a != 15) {
printf...
}
a++;
}

Not a Haskell programmer, but there must be some kind of static linking going on in the Haskell case to bloat a tiny program like that so much. 1.5MiB is just ridiculous, it must be statically linking the stdlib or something.
>>52494941
Hmm I thought my brace indentation was fine anyways thanks for the feedback

It should be:int main (void) {
while (...) {
if (...) {
do_this();
}
do_that();
}
}
Also consider using a for-loop:for (int a = 10; a<20; a++) {
if (a != 10) {
printf...
}
}
which may read nicer to some people.
Other than that it looks really good - keep at it!
