Golang is retardedly easy to pick up, and if you want to understand exactly whats going on inside a package its very very easy to read and figure out. You have to intentionally try and be obtuse to produce hard-to-read code in it.
Everything else looks like worthless "web developer bootcamp" material.

>>60853516
Just look at any python code.

>>60853504
I haven't read all of it but you free (delete) your string before you return it. That's probably what's wrong here. You just need to not do that. Let it be the callers responsibility to delete the allocated string.
So remove the line: delete[] binaryTxt;

>>60853516
No, only the result of teaching people python.

>>60853526
okay thanks, so does that mean that when that after the function returns a value, the memory used in that function automatically frees itself?

I'm kinda new to pointers and stuff.

>>60853411
Usually you allocate the array (even if its on the stack) before calling the function. For example:

void
fill_array(int *array, int size)
{
    for (int i = 0; i < size; ++i)
        array[i] = i;
}

...

int array[5];
fill_array(array, 5);

That's static allocation. Usually you don't want to do this, but for example you could also do the following:

void
fill_array
{
    int *array = (int*)malloc(5 * sizeof(int));
    /* Fill the array somehow */
    return array;
}

Obviously in the latter case, you also have to free the allocated array later.

>>60853582
The latter function should've returned an int pointer. Anyway, you get the point.

>>60853582
>>60853595
wait, so you allocate the memory in the scope containing the function and then pass it as an argument into the function? Then after the function has returned a value, you free the memory in the same scope you allocated it?

>>60853554
No it means it doesn't. You need the string outside the function right? In that case you want the string to remain, it shouldn't be deleted.
A pointer just points to something. In this case a std::string. With the 'new' operator you asked the computer to allocate some memory for your pointer to point to so you can store the string. It will remain until you deallocate it (delete it). So it will remain even outside the function. But you don't know where it is unless you return a pointer to it. Which you are doing.

Also you have a problem with your while loop.
You wrote while(cond=True) this assigns cond the value of True and the checks if cond==True
You almost certainly meant while(cond==True), checking if cond is equal to True. Or even shorter: while(cond)

>>60853430
>if I see another keyboard I swear I'm gonna fuckin SHIT
w-what?

>>60853617
Yes, you can do that. Of course if the array is on the stack, you don't need to explicitly free it (as in the first example).

>>60853740
Rust for Karl Marx.

>>60853816
?

>>60853740
Rust introduces a new “box” type with dedicated syntax for heap allocated objects, which are called managed objects.

Rust supports multiple management strategies for boxes, associated to different typing rules.

The default management strategy for boxes ensures that boxes are uniquely owned, so that the compiler knows precisely when the lifetime of a box ends and where it can be safely deallocated without the need for extra machinery like reference counting or garbage collection.

Another strategy is GC, that uses deferred garbage collection: the storage for GC boxes is reclaimed and made available for reuse at some point when the Rust run-time system can determine that they are not needed any more. (This may delay reclamation for an unpredictable amount of time.) References to GC boxes need not be unique, so GC boxes are an appropriate type to build complex data structures with common nodes, like arbitrary graphs.

Unlike C, Rust forbids sharing of managed objects across threads: like in Erlang, objects have a single owner for allocation, and most objects are entirely private to each thread. This eliminates most data races. Also the single thread ownership implies that garbage collection for GC objects does not require inter-thread synchronization, so it is easier to implement and can run faster.

I wonder what people think when they stumble upon one of my codes.

I was writing a program that reads and prints the first nth lines to the stdout:
>>
>> import std.stdio;
>>
>> void main(string[] args)
>> {
>> import std.algorithm, std.range;
>> import std.conv;
>> stdin.byLine.take(args[1].to!ulong).each!writeln;
>> }
>>
>> As far as I understand the stdin.byLine.take(args[1].to!ulong) part reads all the lines written in stdin.
>> What if I want to make byLine read only and only first nth line?


I was actually just looking for ways to read the first n line and then print it ($man head). My current program
1. reads all the lines provided by the stdin (bottleneck)
2. takes the first n lines (bottleneck)
3. prints each line


I want to
1. read all the lines
2. when line number n is reached, stop reading the rest of the input
3. print each line


Sorry, I am new to functional paradigm

There aren't that many features that you would need after 98, unless you want to use the standard library. But then, if you think you need a structure or functionality from the standard library, just search for it on the internet. Templates and the like to my knowledge also exist in 98 anyway, so there's really not much for you to learn there.

>not any better
Not better than what? It's better than the D version because lines() doesn't read anything, it returns a lazy iterator, then take() and map() modify this iterator and it's only via count() the IO actually gets executed. Oh, and the result code is a tight loop without any calls, possible even unrolled.
>>60854512
You have to handle all the possible errors in the code itself, for example with .unwrap_or_default(), or .unwrap_or_else(), or by matching the result manually. Equivalent D/Java/C# code would compile without error handling but then produce exceptions during the runtime, which is not very safe. In rust you can ignore error by unwrap(), but you don't get any surprise crashes, because you wrote than unwrap yourself.

module Tree
   data Tree : * -> *
   empty :: forall a. Tree a
   leaf :: forall a. a -> Tree a
   node :: forall a. Tree a -> Tree a -> Tree a

compute the hash of the key
allocate a buffer the size of the number of elements in the resulting bucket (or use amortized spatial growth if the table is open addressed)

return the buffer (must be freed by caller)

how do I print out the rows in which there are duplicate elements in the first field?
I know how to cut out the first column and run uniq on that, but I struggle to keep the second column intact

I started off with sort -k1,1 to sort by first column, though uniq -D -fN is giving me shit by only allowing me to skip the first N fields, not having an option I can find for using the first N fields

this is all to guide me in finding duplicate files by comparing md5sums (and comparing the md5 sum to the filenames, to see if the alleged md5sum in the filename matches the actual md5sum)

most of the stuff I found has been awk and grep stuff unfortunately, which I suppose might work but then again should it really be necessary when there might be some utility that does it cleanly

the closest thing I have found thus far is reversing so that I can count fields from the end, but unfortunately the later columns contain spaces so unless I manage to replace them somehow, or insert a different field separator, reverse + uniq + unreverse would not work either

and reversing is an incredibly hacky solution desu

You are pretty ignorant. Most of the programs don't run natively, they run on software platform like browser or vm. This creates overhead.

Just checking out C for the day? Just go back to Python, little boy. This area is for grownups, go play with your toys in the toy room.

I created
thisisfun.xyz
An ad free e-hentai archive with usability, free downloads, and almost 18,000 mangas and doujinshi already queued.

Im working on a way to earn more gp on e-hentai so that the archiver can function. Does anyone know an automated way of doing so?

planning for next weeks work, should I report this to CEO of the company as a contractor?

i was brought in to rescue an API which was written with zero tests in place. the language they chose to build it is not something i would have chosen -- for web development, there are far better choices for reaching business goals. unfortunately the technical lead of the company and the guy who worked before me on the APIs neither understand this, and have chosen the current stack purely according to flavor of the month on HN without evaluating what it brings to the table. they have put their own kubernetes system in place, without gathering statistics on what parts of their microservice architecture (code copy-pasting architecture) gather the most hits. they dont know how often their APIs are queried, thus they cant possibly know whether k8 solves anything for them.

AWS spendings are just over 1K a month, but i think they would be better off with a single ass dedicated server rather than paying whatever AWS hosted k8 is charging them for automatically scaling pods.

i wish i had the luxury of not working for clients whose founders do not have technical background. this tech stacks by HN shilling is an utter non-sense.

should i report to the CEO or just do in 100 hours and ask for a raise?

No.

>>60859700

I replaced it with exec a bit later, the manpage said execdir was safer, though maybe that is for cases where you are executing the actual results you find furthermore

How would you go about helping someone with structured text when your only experience with it was extrusion?
