anyways its scraping the harry potter wikia in its entirety (finished), converting to an appropriate tabulated format, converting to .opf (xml-style format), then converting to .mobi (dictionary-style format for kindles)
should take another 3 or 4 days but in the end you should have a dictionary for when you're reading on-the go (so you could click any word that says worms and get the definition in the harry potter universe)
it'll be great
can be ported easily enough to other wikis too
cool, right?
how is this:
>var facts [10001]*big.Int
facts[0] = big.NewInt(1)
big_i := new(big.Int)
not infinitely worse than:
>BigInteger[] facts = new BigInteger[10001];
facts[0] = new BigInteger(1);
BigInteger bigI;

New to programming here. Why would something like n % 3 = 0 mean something is divisible by three when 6 % 3 = 2, etc.
>>54972401
oh now
what type could this be eh?var facts [10001]*big.Int
big int since that is the value you are assigning it!
compare that toBigInteger[] facts = new BigInteger[10001];
hmm... why do I need to write the type both times?
>>54972425
the java syntax is by far more consistent and readable you complete moron

consistent. readable.

oh pajeet
in good languages you can't declare Null variables
so you are left with thisFoo foo = new Foo();

var foo Foo = Foo()
or

hello pajeet,
inheritance, like java with it no type inference, is outdated
interfaces are the proper way to do object oriented code, alan kay didn't think of java with his OO definition
>>54972599
disgusting as shit, with the new operator it's more readable because you know that you're constructing a new object, and 'Foo' at the start of the line conveys a shit ton more information than 'var'

>mpz_fac_ui
sorry, I hadn't seen this post.
mpz_fac_ui is much faster (at least 5x) than both versions, C+mpz_mul_ui and the Go code I posted.
mpz_fac_ui would be equivalent to facts.MulRange(1, 10000) in Go, which takes ~ 2x the time mpz_fac_ui takes (including printing):package main
import (
"fmt"
"math/big"
)
func main() {
facts := big.NewInt(1)
fmt.Println(facts.MulRange(1, 10000).Text(10))
}

I don't know about Go in particular, but type inference is a done deal. Seriously, it's a "solved" problem. HM type inference (and derived systems) is very simple, reliable and robust.

Nice GC and memory usage, retards.
This is just me repeatedly opening and closing a windows form in C#.
>70mb
How do you find this acceptable for a simple forms application? And the GC is completely useless too, didn't free fucking anything, even though all the forms resources go out of scope when it's closed, it still hangs around even after a GC pass.
>>54975011
Maybe it's too smart and decided not to free stuff you'd be opening a second later
>>54975011
doesn't seem too weird, open up firefox or someshit it's like 500 MB or something for a single blank page
>>54975027
Except even after I leave it sitting for a few minutes, it doesn't make any more GC passes until I start opening forms again, and no memory ever gets freed.
>>54975051
Well, that's what you get for using literally any language other than C or C++
>>54975037
Yeah, but Firefox does a shit ton in the background.
I'm not doing much at all in the background.
>>54975065
I know, it's not like I had a choice, we have to use C# and Java (kill me) in the course I'm taking.
I use C and C++ at home.
>>54975051
it's supposed to avoid doing GC passes until it's absolutely necessary
>>54975077
At least neither Java nor C# have unions in, which as we've been taught earlier by the Java cleric, are literally the devil, are retarded and are completely unnecessary in a language
>>54975078
Yeah and when it does, it frees nothing.
See pic in >>54975011, those yellow marks are GC passes.
>>54975120
a GC pass clears the heap but you still have the memory allocated for the heap
>>54975140
No I don't, all resources used by the form are inside that instance, when I close it they shouldn't be allocated anymore, and the GC should be collecting them.
I don't keep references to the form instance after the function the button calls returns.
>>54975187
yes you do, the program works the same as when you have a custom allocator in C/C++, you have a chunk of memory allocated and just because you free some objects doesn't mean you deallocate the chunk of memory
>>54975286
You're talking about something completely different.
Get out and stop changing the subject.
Can anyone here answer >>>/sci/8130752 ?
>>54975011
Just use the unsafe keyword and manage your own memory.
Use a memory profiler. I guarantee you're sitting on uncollected event handlers.
Also, just because you close a form, doesn't mean it is disposed. The object can still be in scope.
>>54975382
It's declarative programming, sounds like a rule based system
>>54972346
Solves sudokus. Simple case of value evaluation. Basically fizzbuzz.
>>54975388
How to properly cleanup the form?
>>54975435
I have no idea what your code base looks like.
I cannot help you with your issue without the entire repository.
Even still, this anon:
>>54975286
>>54975140
is right.
C# (and Windows in general) will allow the application to maintain allocation of memory, even if that memory isn't being used.
As for scoping issues, a basic example:var form = new CustomWinForm();
form.Show();
form.Close();
GC.Collect();
GC.WaitForPendingFinalizers();
The GC does nothing here, because the object is still in scope, even though it is 'closed'.
This goes for any other event handlers or objects you may have given global scope within a class.
>>54975507
My form goes out of scope when the event handler returns though.
>>54975561
It's nice that you think that, but without your code I cannot show you where you are making a mistake.
There are plenty of questions on SO dealing with your exact issue: making a basic form, opening and closing it, and seeing the memory just keep going up.
It's almost always an issue with instantiating a new form object and never actually leaving the scope, or having the event handlers still within scope.
>>54974361
Sure thing faggot.

>>54975589private void btn_stats_Click(object sender, EventArgs e)

I'm not sure what you mean by global event handlers, is that some C# thing? as far as I know when any object local to that one function go out of scope they are to be garbage collected.
>>54975627
>enum class

also can't do this:
>>54974375

>>54975688

>>54975699

>also can't do this:

Also
>currency
>floats
I really hope it's not doing what I think it does.
>>54975693
are you not listening to me? GC firing has nothing to do if it decides to free or not. A GC does not imply itll clean up evwrything immediately, most GC algorithms are free to delay until needes as to not hammer you with freeing constantly.

yeah
>>54974650
lmaoing my ass off
>>54975762
well first of all you should probably read up on TCP and build on top of it like HTTP does rather than making a protocol that works directly to IP. Then its just a matter of defining a spec as far as requests that will be expected and their answers dependent upon the application.

I'm working on the very last steps of a multithreaded C server and signal handling is kicking my ass.
I'm trying to randomly select from two outcomes when you kill a monster. I can only make the first one appear. I know I'm missing something obvious.
code in pythonchoice = random.randint(0, 1)
if choice <= 1:
message('The ' + monster.name + ' is dead! You gain ' + str(monster.fighter.xp) + ' experience points.', libtcod.orange)
monster.char = '%'
monster.color = libtcod.dark_red
monster.blocks = False
monster.fighter = None
monster.ai = None
monster.name = 'remains of ' + monster.name
monster.send_to_back()
elif choice > 1:
message('The ' + monster.name +' has surrendered!')
monster.char = '*'
monster.color = libtcod.dark_red
monster.blocks = False
monster.fighter = None
monster.ai = None
monster.name = 'A surrendering ' + monster.name
monster.send_to_back()
>>54972280
Interested in this.
>>54976157
No shit. You can get a 0 or a 1 as result, and the first option happens every time you have anything equal to or lesser than 1.

I'm gonna go ahead and ask.
Let's say I have a bunch of threads all trying to handle connections from a list while inside a while(condition) loop.
Condition is a static volatile sig_atomic_t.
Now on receiving a certain SIGCSTM I use sigaction to run a one line method which flips condition to 0, and thus the threads should all exit the while loop after finishing up their current connection and rejoin main, then killing the server quietly.
Though when I throw the signal, nothing happens. The server just hangs as if waiting for more connections.
I'm handling the signal by doingstruct sigaction s;
memset(&s, 0, sizeof(s));
s.sa_handler = shutDown;
sigaction(SIGCSTM, &s, NULL);
while the method isvoid shutDown(){
overlord = 0;
}
Anything glaringly wrong here?
>>54976300
Yeah don't run thread per connection, that's insanely retarded.
>>54976331
I don't run a new thread for each connection, the server starts with a thread pool of size specified by the user, and each thread in the pool looks inside a shared list which a specific dispatcher thread fills with accepted sockets.
If they find a socket ready to be read on that list they take it out of the list and work with it until the client on that socket disconnects, then go back to looking at the list.
It's in the program's specifications, I can't really work around them.
let foo = Foo::new();
all other languages btfo
>>54976433
HON HON HON
>>54976389
Hmm, maybe try adding:s.sa_flags = 0;
sigemptyset(&s.sa_mask);
Also could it be that the call to accept is simply blocking waiting for a new connection and thus the thread does not see that it should terminate?
>>54976225
he got it much faster here than he would have in /sqt/
>>54976565
He didn't even get the image he was requesting, moron.
There's a longer one specifically with the mixture.
>>54976433
'Foo' is more interesting to know at the start of the line than 'let'
>>54976457
I think I found my problem. My dispatcher stops on the accept function, and my workers stop on the conditional variable the dispatcher uses to warn them a new element has been put into the socket list.
So I'm gonna try implementing a select call before my accept on the dispatcher and see where that goes.

Is there an easier way to do this? Like a way to turn a directory tree into a block device or something?

What should I read to learn more about multithreading in C#? I want to improve the performance of my puzzle solver by having the solutions checked on multiple threads simultaneously and then have a background thread read valid solutions found off a stack and write them to the console window. The msdn example is pretty confusing.
can someone explain data-driven programming vs message passing programming to me?
>>54977481
>What should I read to learn more about multithreading in C#?
Firefox source code. You should implement each thread as a separate process.
>>54977481
This video is pretty good and gives concise examples using LINQ:
https://channel9.msdn.com/blogs/bruceky/how-to-parallelize-your-application-part-3-using-tasks
It goes over the difference between just throwing a thread at each iteration, and utilizing a thread pool of workers that complete tasks as they can.
>>54977481
>>54977903
Oh, and that's part 3 where they actually go over the code. The first two parts are good if you want to understand the entire concept and when to use it.

This is plain wrong. The bottleneck is printing the number out. If you eliminate that, C is faster than Go.

not that it matters, but how come C is slower than memelangs at doing console I/O?
Idea: message board that allows you to "attach" a file to a post. Instead of uploading the file to the server, the server just mediates a WebRTC file transfer. The "attached" file is removed when the uploader's session ends (since no one is able to receive the file if the uploader isn't online).
>>54978328
Yeah, let me just upload a popular image and have millions of computers nuke my connection.
>>54978280
No clue. Here are the numbers to back up my claim btw:./facts-c 0.03s user 0.05s system 98% cpu 0.088 total
./facts-go 0.11s user 0.06s system 108% cpu 0.157 total
I changed it to 13000! to make the numbers a bit bigger. I'd post the gist with all the code + makefiles but fucking spam filter
>>54978358
The website could handle queuing, but still, good point.
I'm not sure if it is straightforward with the APIs that exist, but you could load balance downloads among all active sessions that have downloaded the file. Else, you could do full on bittorrent-over-WebRTC.
>>54978395
Could set up some kind of p2p, so that people who have downloaded the image also start uploading (wow, I just invented torrents!)
Your idea also already exists, but I can't find the link right now. It's just a small demo that lets you share files p2p with webrtc
