i've seen people do this. assigning NULL after freeing the object. is it correct?

int *r;

r = (int*) malloc(sizeof(int) * N);

free(r);

r = NULL; // why this?

you should never cast malloc

>>55243349

Assigning NULL after free is a safety mechanism to keep yourself from accidentally using a pointer you just freed. If you were to later malloc a block that happened to correspond to the same address, the result could be some rather undesirable behavior.

That said, if you know you don't use the pointer afterwards (i.e. you free at the end of a function), there's no point in nulling it.

So currently I have a wget script that downloads a bunch of files. How can I redirect all the files that it downloads to another folder? I'd like to keep the filenames it produces.

>>55243639

-P prefix
--directory-prefix=prefix
           Set directory prefix to prefix.  The directory prefix is the
           directory where all other files and sub-directories will be
           saved to, i.e. the top of the retrieval tree.  The default
           is . (the current directory).

>>55243657
I tried that and it did not work. Now I noticed that I had a typo in the folder name. Thanks anon.

Can anyone recommend some resources for learning Mathematica? I'm fairly competent in C, C++, Java, but I have no idea what this shit is.
Like, I just have to write simple stuff that takes the average, does Fibonacci up to a number n, but all the youtube videos I see people just type in "table, graph" and it's all automatic. Like how do I write a function/method?

I'm about halfway through Dive into Python right now, and it's a really good book, but what are some good beginner/intermediary projects to put my skills to the test.

>>55243675

Oh no still doesn't work. This is how it looks like atm:

From my introductory programming class:
>In this problem you will be creating a game that you play against the computer. Make a class named GuessingGame - when executed, this program should randomly generate a secret integer from 1 to 100, and then instruct the user to try to guess what it is. After each guess the program will tell them if they are too high, too low, or if they got it right - and if they got it right it will congratulate them, tell them how many guesses it took them, and offer to either play again or exit
the program.
>Make a program that reads in text file of fractions with the format:
8/4
2/3
4/6
and so on. Then have the program reduce all the fractions, and find how many instances of each fraction there are. Do not print the same fraction to the screen twice.

I don't know, boring stuff like that. You should just program what you think is cool, otherwise I don't think it'll be very fun for you.

>>55243373
>you should never cast malloc

On the contrary, you should always. Malloc returns void pointers, which should be casted.

>>55244323
There is literally no advantage to casting void pointers.
C guarantees that void pointers will be converted to other pointers automatically, and vice versa.

If you free the memory block r points to and later try to access it via r, that'll be an error -- which of course shouldn't be an issue if you know what you're doing... but I guess assigning NULL to r is a way of allowing to at least test, later on, whether r points somewhere or not.

>>55243349
You should only free pointers if you're going to reuse them immediately or at the end of the function.

Also, I already tested this.
Free'd pointers return NULL automatically.

>>55244886
>Free'd pointers return NULL automatically

How? Is free() a language construct thing rather than a normal function? I mean, the pointer sure does return NULL after being free'd, but how does this happen since the pointer is passed by value? Is it not a compiler thing rather than a language standard thing?

>>55244934
I mean "is it a compiler thing", not "is it not".

Trying to make a function which when the user reaches page 1 and tries to turn the page further, rather than crashing my app (by trying to get page[-1]) it will reset the page number to the last page of the book (i.e. so the pages loop)

This is just a basic version.

let Pages:[String] = ["001", "002", "003"]


Pages[1]

var currentPage:Int = 1


func test() {if currentPage == 0{
       var currentPage = 3
    } else {
        var currentPage2 = currentPage
       currentPage = (currentPage2 - 1)
    
    }
}

Is this a valid method of creating a loop of pages?

Replace with:

       var currentPage = Pages.count()
    } else {
        currentPage--;

Alternatively Pages.length or whatever your language calls it, and currentPage = currentPage - 1;

What language is this anyway?

var currentPage = Pages.count();

JS in Unity has some cleaner syntax for things like coroutines but I still prefer C#.

And screw people who give "ew"s. Sure there are better 3D engines and maybe Unity encourages some less than great habits for its target demo of newbies but as a tool it is quite capable for quickly prototyping behavior.

If you haven't tried it in a while you should, it had quickly gone from cheap 3rd party software to powerful well documented software.

Making stuff.

I think I may have done something amazing /dpt/

My job does a lot of programming, but the whole office is confined to choosing between Groovy, Jython, or Nashorn (basically JS with Java methods). This is because we're writing scripts inside a crappy java environment and don't have access to the server itself

I don't like Java, and most of my coworkers don't like it either, so tonight I wrote a script in Nashorn that just lets them run almost any executable single file from a URL (input doesn't work but doesn't need to, node and rare languages don't either but there's no way around that)

You know the worst thing about automake? The fact that no matter how perfectly your Makefile "just works", someone will come along and make a fucking issue of how you "need" to use autoconf for "muh portability".

>>55246810

Suddenly your code doesn't "just work", instead, your build steps start with "download and install cmake". Bonus points if it requires a specific version of cmake, although that's mostly an autoconf problem.

The last thing I made was a simple filter to remove attributes from HTML tags (leaving just the tag name and brackets) and remove all the extraneous tags I don't need.

>>55247941

Does /g/ ever team up to code anything? Why don't we have open source projects going?

it's basically a meme at this point that /g/ can't do anything together.

When you first start, you decide on a license and /g/ can't even manage that one without fighting over MIT and GPL.

>>55247916

But since you didn't edit the build script, the custom script that needed to be run to generate some other file needed didn't get run, and so the program either failed to build, or had some sort of runtime error. Try again.

YOU DON'T GET TO BE IGNORANT OF YOUR PROGRAM'S BUILD SYSTEM.

Oh yeah, I would absolutely expect it to be a dictatorship. And our dictator would have to be a professional autist wrangler. I just think it would be nice to have a group project to work on.

So if someone wants to host a project just hmu senpai, we'll chat shit and submit pull requests and stuff, it'll be great.

>>55248147

I am not pushing any goal posts, I am merely pointing out edge cases. "Just hit build" doesn't always work. Project requirements may change, and may even be outside the scope of what your IDE has buttons for dealing with. It is of absolute necessity that a programmer understand the build script and how to manipulate it for edge cases where necessary. Some of the things I'm pointing out are not too uncommon. Building for different platforms, for example. I might have some .c and .cpp files dedicated to the Windows UI, some to using GTK on Linux, and some .m files for working on Mac OS X. Now I have to add in an objective C compiler, but only when I'm compiling for Mac OS X. I have to link against GTK, but only when I'm building on a Unix system. And Visual Studio assumes you're probably only going to be developing for Windows.

>>55248204
I'd be willing to join, but it has to be in C.

Also, what kind of project are you thinking of?
It has to be a real goal, not just "whatever".

>>55248121
Then why don't you use a template to generate your makefile, .sln, or whatever depending on your platform, IDE, etc.

>>55248237
That's exactly what Cmake does

>>55248234
The details like what language and what the project would actually entail would be up to the dictator. The problem is finding someone who has a fitting project in mind and is willing to take responsibility for it. I'm sure as hell not going to do it myself because I'm not cool enough, and I don't have enough experience with open-source software development.

>>55248237

That is one option. I have merely yet to find any template systems for doing this that I find easy to work in.

Don't cast in C, static_cast in C++.

>>55247879
>>55247907
You rarely edit .sln files, and you don't need them to build things.

The main reasons to change them are either to add a new project or to add dependencies between projects, and this is easily done in Visual Studio. If for some reason you don't want to do that, you don't have to use .sln files at all.

You only need to know how to write MSBuild scripts, and most build script changes happen to .csproj files which are in this format.

I hand-edit .csproj files all the time, and they're at least as good as GNU makefiles, if not better. They're written with XML rather than a special snowflake language, and it's not cumbersome because all the heavy lifting is done with build tasks that reside in a DLL or inline code.

    | Add(f, g) -> Add(d(f, x), d(g, x))

>>55248758
I can see how it's useful but it doesn't seem that special. If I understood the piece of code you just wrote (I have almost zero Ocaml knowledge so correct me if I'm wrong), a javascript equivalent would be this:

var expr = {
    "Int": typeof(0),
    "Var": typeof(""),
    "Add": (a, b) => a * b,
    "Mul": (a, b) => a * b
}

var d = (f, x) => {
    if (typeof f == expr.Var)
        return 1;
    if (typeof f == expr.Int)
        return 0;
    if (f == expr.Add)
        return expr.Add(d(f, x), d(g, x));
    if (f == expr.Mul)
        return expr.Add(expr.Mul(f, d(g, x)), expr.Mul(g, d(f, x)));
}

Sure, the syntax of your code seems to be lighter, but that really doesn't seem like much.

Honestly from looking into it more, it looks like what I should be doing is make a website where people can post their open source projects, and let devs search through them freely to find ones they are interested in. Maybe using the github API, or just making my own directory entirely.

>>55243754
Sure you want it to be $1? You're already passing in that argument as an url, urls don't make very good folder names. In case it's what you want, do

mkdir -p $1

prior to that, maybe wget doesn't want to create it itself.

>>55249109
Depends on the interviewer. Personally I'd go for the latter.

>>55249220

"Add": (a, b) => a + b,

if (typeof f == expr.Var) {
  if (f == x)
    return 1;
  else
    return 0;
}

ftfy. Apart from that, that's almost as good as the Ocaml version I'd say. (not him) It wouldn't be possible in a memenamically typed language, but whatever. I'd say it lacks a bit of constraint, in that you don't have tags to disambiguate between vars and ints, you just rely on a careful choice of underlying types. Could be fixed while doing it in JS tho. Another thing you have carefully avoided here is the fact that pattern-matching, beyond checking the structure of the value, actually lets you deconstruct it and bind variables to what it contains... Wait wait wait! where is g in

d(g, x)

coming from? you're not storing the operands of Add and Mul in the expression datatype and you should be, redesign this. (Not slamming you, I know it's quick and dirty.) Yeah, pattern matching is more handy and intuitive in this case.

I give you two strings with lowercase letters. You return a string which corresponds to the middle point between them, that is, there must be as many possible strings that fall in lexicographical order between the first string and the middle point, than between the middle point and the last (respectively included and excluded in both cases). I'm convinced it's possible.

Alternate formulation: a random string comprised within the given interval should be as likely to fall in the first half of the interval than in the second. Bonus points for arbitrary alphabets (I think there's a huge catch but I'm not telling you), and fine tuning based on the different probability for each letter to appear. Good luck! I'm doing that too.

Pic related: what I posted yesterday, "how to average two floats in C++". I think you can always go for

x/2 + y/2

, EXCEPT if one or both of x and y is

std::numeric_limits<T>::denorm_min()

, in which case

(x+y)/2

has better chances of success. Agree or disagree?

Not the guy you replied to, but couldn't that be done pretty simply? Example with numbers:
low = 10
high = 20
mid = low + ((high - low) / 2)

The same thing would work for strings, except you need to map characters to numbers first. You could do that in a number of ways, convert to bytes, get ascii or unicode values, a=1 b=2 c=3... etc. whatever you feel like really.

Unless I misunderstood what you meant.

I don't hate Lua though.
It's neat.

>>55250311
Lua is comfy for scripting.

>>55250311

Eh, I've seen mixed opinions on Lua here. I personally dislike it because it's rather weakly typed. On principle, I dislike any language where a string can be implicitly cast to a number of which it is a string. For example, in Lua:

"2" + 1
=> 3

In Javascript:

> "2" - 1
1

And in Perl...

$ perl -e "print('2' + 1);"
3

I hate every one of these languages because this results in a valid result, rather than a runtime type error.

>>55250407
In practice this has never caused me a problem
has it for you?
and if it has not, then what is the issue?

>>55250311
I like Lua a lot, in fact, I've been using it for the past 8 years or so for scripting. It's a simple language with clean syntax that's easily extensible, what's there to not like?

>>55250407
Yes, yes, dynamic typing is shit and all, but for languages that are very small and designed for scripting, it's permissible.

>>55240950

>>55244392
There are multiple .arc formats floating around, you'll need to find the format specific to your application.

>>55250624

It is not a problem with dynamic typing. Ruby and Python give reasonable outputs when you try to do any of that shit.

Ruby:

irb(main):001:0> "2" + 1
TypeError: no implicit conversion of Fixnum into String
    from (irb):1:in `+'
    from (irb):1
    from /usr/bin/irb:11:in `<main>'
irb(main):002:0> "2" - 1
NoMethodError: undefined method `-' for "2":String
Did you mean?  -@
    from (irb):2
    from /usr/bin/irb:11:in `<main>'

Python 3:

>>> "2" + 1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Can't convert 'int' object to str implicitly
>>> "2" - 1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for -: 'str' and 'int'

>>55250447

It's less so much that it's caused me problems, so much as I don't like languages in general that try to produce a result no matter what. In Javascript, you can get a valid result for adding undefined and true. The answer? NaN. Why yes, the result should not be a number, but don't you think you could instead just maybe crash the fucking interpreter instead? Or throw some sort of exception? I can tolerate C's weirdness because you can sort of just say "okay, all pointers are integers" and leave it at that, but if a language is going to be higher level than C, it should at least try to have a respectable type system.

I did a game in Love2D and it taught me why I hate dynamic typing.

It felt liberating to start with but when you run your code and accidentally reference a nil value that would have been caught at compile time instead.

It just costs too much time to do that. I don't have any other major complaints. It's a fairly simple integration in most codebases.

Weird

>>55250864
Actually, I figured it out.
Since lua isn't taking its input from an interactive device (a terminal), it handles things differently, and "2" + 1 isn't a statement, so it doesn't parse.

lua <<< 'print("2" + 1)'

works

I had a strange problem while working in C recently.
OS refused to recognize Interruption Handlers until after a first reboot. Anyone ever experienced anything like that?

I just read some articles about how a LOT of people can't be TAUGHT programming:

https://blog.codinghorror.com/separating-programming-sheep-from-non-programming-goats/

>The test was administered twice; once at the beginning, before any instruction at all, and again after three weeks of class. The striking thing is that there was virtually no movement at all between the groups from the first to second test. Either you had a consistent model in your mind immediately upon first exposure to assignment, the first hurdle in programming – or else you never developed one!

I am not one to believe we are special snowflakes. But does anyone have any input one way or the other?

Ok. Because everyone in my family has a good grasp of programming and we were raised quite differently due to outside circumstances. So assuming we didn't just happen to coincide I'd assume it's the opposite. Though I don't know either obviously. 5 isn't a large sample size.

>>55251364

The problem is "loose" typing, but the loose vs strong argument has somehow confused a lot of people in the dynamic vs static stakes.

This. If you don't write the assembly yourself then you're a shitter that doesn't belong in /dpt/.

cryptopp or botan?

is it true that reading the qu'ran will make you a better programmer

>>55252487
More like write the code as you want it executed.
I wish C++ had force inline.

No. We'd have predominantly middle-eastern cyber-attacks rather than physical attacks.

why would muslims perform cyber attacks lol

what does /dpt/ think of muslims

>>55252630
I oppose practicing religious people. Most Christians I meet aren't really practicing in a practical sense. They have their rituals they perform in churches but don't make decisions based on WWJD for instance.

Same can be said for many Muslims. But sadly the anti-pork reminds me that they're 'different' every day. So I have a primal bias against them i have to fight.
That's my opinion not /dpt/'s.

but why are you islamophobic? muslims are our friends, pork isn't even very tasty and it comes from a dirty animal

is it true that cute boys dressed in hijabs are the best programmers?

int result = 0;
    result=17047*HashMapSize*Coordinate.ChunkX+16937*HashMapSize*Coordinate.ChunkX;
    result=result%HashMapSize;
    assert(result==0);

This assert doesn't fire ever.
Why?
HashMapSize is 50. This just seems too unlikely.

Does your build script define NDEBUG? Are you in release mode?

Can you help me please, /dpt/
Trying to fix the code of someone who wrote a tool to convert Nintendo's downloadable files into a CIA file (that can be installed on a 3DS), getting the following errors. The guy has set =std=c99 in the makefile and someone said that these 2 things would conflict so I'm not sure what to do.

The original code is here https://github.com/Tiger21820/ctr_toolkit/tree/master/make_cdn_cia
Using Ubuntu 16.04 and the usual build tools to compile.

gcc -std=c99 main.c cia.c utils.c -o bin/make_cdn_cia
utils.c: In function ‘GetFileSize_u64’:

  size = ftello(file);
         ^
utils.c: In function ‘TruncateFile_u64’:
utils.c:162:9: warning: implicit declaration of function ‘truncate’ [-Wimplicit-function-declaration]

I decided to replace it with a real hashing algorithm (something which wasn't just made up on the spot). Doesn't matter anymore.
I'm in debug mode.

>>55253025
Dunno if other anon's idea of assert being disabled holds up, but try assert(0) to isolate whether assert is enabled or not. Also are you sure that this path in your code is even taken at all?

>>55253025
okbye

>>55253025
Nope. Nevermind. That doesn't work either.

    int result = 0;
    char data[8];
    ((uint32_t*)data)[0]=Coordinate.X;
    ((uint32_t*)data)[1]=Coordinate.Y;
    result=SuperFastHash(data, 2)%HashMapSize; //http://www.azillionmonkeys.com/qed/hash.html LGPL 2.1 license. http://www.gnu.org/licenses/lgpl-2.1.txt

This always gives me 49
>>55253086
I removed the assert and just inspected the value (I just used the assert because it was always 0 before it seemed so I just wanted to run it for a while and see).
>>55253099
:(

are session beans just a java buzzword for RPC?

>>55253015
Kind of weird... Looks like he doesn't know about feature_test_macros(7) (see the manpage). The glibc nowadays only defines certain recent function if you pass it a preprocessor flag that says you are writing recent code for recent stdlib interfaces. It's good for not breaking old code that defines "truncate", as well as ensuring you're conforming to the least common denominator, I suppose. In your case, add

-D_POSIX_C_SOURCE=200809L

to the compilation flags and you should be fine. Come back to confirm please.

>>55253015
I don't understand why this is happening, unless for some reason ubuntu's glibc doesn't have fseeko, ftello and truncate???

>>55253199
Also you're right on

 -std=c99

not allowing truncate in. It fixes itself if you select

 -std=gnu99

tho (and also with no flag at all). Can you guess why?

Just fyi:

% cat > test.c
#include <unistd.h>
#include <sys/types.h>
int main() {
truncate("something", 42);
return 0;
}
% gcc test.c
% # (no error)

But -std=c99 breaks it, but -std=gnu99 unbreaks it.

Make me. I'm not going to stop posting my thoughts just because they trigger your fat loveless ass.

at least I tried being useful. Why are you still arguing? Really I'd rather be loveless with my gf than helpless like your wreckage of a person. See you in the afterlife, you extremely late abortion.

>>55253453

as did I. I was just completely off the mark, but I was brainstorming for possible reasons (which would probably lead to discovering what was wrong)

because pricks like you ruin /dpt/. we could probably have a bunch more posters if you didn't make the atmosphere unnecessarily hostile, you fucking autist

>>55253317
Can't try on my side because you're not providing your fixed version, but maybe that's not necessary. Try without the

-o bin/make_cdn_cia

part and tell me whether it produces an a.out file and/or a message.

Why ;_;
This makes no sense.
I tried multiplying the X and the Y by fairly large numbers (1/10th INT_MAX) and it just generates the same result regardless. Different from when I didn't multiply but the input didn't matter.

>>55253488

Should have brainstormed this in your brain rather than spout something so obvious. Try again next time.

I'm sorry that my reply hurt you.

Niggah yo rhymes are so deep!

>>55253490
Removed the -o part and it created an a.out file and a file named '-D_POSIX_C_SOURCE=200809L'
Both are 28.1 kb

>>55253515
I'm supposed to use ChunkX..
Sorry for bothering you. Silly error.

>>55253526
>created a file named -D...
Wut? sure this iteration created it? Delete it and rerun please.
Ok, so now I have to go, try this:
move the -D flag before the -std flag (Yeah I'm out of idea)
if that fails, use gnu99 instead of c99 as an std, it should fix your original issue without introducing another (hopefully)

see you.

And, before I forget, screw you >>55253488 bye

>>55253490
Btw, literally all I have done is take the files from that make_cdn_cia from the github I posted

https://github.com/Tiger21820/ctr_toolkit/tree/master/make_cdn_cia

and fix the basic errors I found by cross-referencing against other stuff I googled, but the fseeko errors are where I hit a brick wall

Okay so I did that, and now just the one a.out file got created this time, 28.1 kb again. Not sure if I'm making progress.

I did try gnu99 as it came up in some other google result but it didn't help much, but I'll try it again with the new information, semen demon as thanks.

>>55253633
>now just the one a.out file got created this time, 28.1 kb again.
a.out is an executable file, it's probably exactly what you want: the final program. Rename it to make_cdn_cia and call it a day, and if it gives satisfaction as such there's no reason to look further. I have an idea for the -o thing but whatever. Also I haven't seen any "copy make_cdn_cia into the system directory" so you'll probably have to do it manually.

Thanks for semen deamon. See >>55253488? Eat a dick.

>>55253751
wtf is that neck

>>55253737
That's not the problem. It's the ratio between the fingers, 'her' Achilles tendon, the wrists, the wig (obvious and doesn't make you male, but it's clearly a factor when your sex is in question), the autistic pose chart on the mirror, the plushies along with the two shoeboxes which still have their lables on them, the shoulderblades and how 'she' doesn't know how to tie a bikini.

It's all terrible. 'She' can obviously be a freak of nature and exibit absolutely no female traits but regardless I'd count 'her' as male because all that's missing is the penis (which given how tight those are I could easily pass like that too, have you never folded your penis inside or something?).

You're right friend, that's the program all compiled.
Not sure if using that flag is 'correct practice' or whatever, but as long as it works I'm happy. I have no idea why that guy wrote it that way, guess there's some reasonable explanation out there.
I might actually start using my own github now for the first time in 7 years.

>>55253841
p.s. I wonder how these trannies can put up with it.
I'm not even that sexually active. No doubt a normal man would spot 'her' as a male from a mile away, blindfolded.

Sounds like a good idea. If you're still around try checking out Open Hatch or Code 52.

How does one communicate over serial using C? I have a microcontroller connected to a computer using a usb. Ive tested it by using minicom to trigger the microcontroller which worked. Now I want to write my own code to trigger it on the host computer instead of using minicom. Is there some kind of file I write to or a library I need?
