Working on my path tracer. Got Multiple Importance Sampling working today (pic related. MIS reduces the variance for points close to a light source introduced, which was introduced by next event estimation, since that doesn't take into account the light encountered in a random walk for diffuse materials).
Also implemented a quick tone mapping algorithm so my HDR environment maps give something presentable.
Next up is coming up with a decent stratification scheme to further reduce variance.

Not sure if this is the place to post this, but I'm working on some hacking techniques for a class. We're supposed to hack a class-prepared website. I've tried sql injection, cross site scripting, and remote file inclusion, but neither of these seem to work (remote file inclusion isn't working because there isn't anywhere in the POST request where I could put it). Does anyone have any ideas on what else I could try?

What does an AST for a type/struct deceleration typically look like?

https://www.google.co.uk/images?q=AST+type+declaration
/dpt/ I have a micro optimization question. I see conflicting reports on the performance of int32 and int64 on x86 and x64 systems, some people say an int32 will work best on both, some say the int32 will be slower. Regardless of those 2 types though I'm wondering about even smaller ones, would using an int8 or int16 be worse than using the native int type?
I am sending data over a network and figured using the smallest possible type for my needs would be best so I'm stuck with it regardless but I want to know for future reference if it actually makes a difference. I figured a smaller type than the native would be fine, only bigger would be problematic but I don't actually know.
>>54090106
Unless I'm missing something, none of those show what I'm asking for.
>>54089840
It's true.
I only post in here when the OP pic is hime.
Hi dpt, should I pick up a book on Lisp/Scheme to go along with reading SICP?
Is there some XOR predicate-wise in prolog?
The if-statement looks really ugly, since the 'else' clause is just a repeat of the conditional, but I assume prolog needs it to ensure determinism in unifying X.
Otherwise i would simply have written(fizzy(N,X) -> true; atom_number(X,N))
instead.
Might seem like a trivial problem, even though I deem myself fairly advanced in Prolog.
>>54090266
Are you doing any computing using the int or simply sending it over the internet?
>>54090570
In this specific case it's just a handle which gets used as an index later, the only computation done on it is -1 and +1 to shift it to/from 0 base index to 1 base. I have it as a uint8 because there should never be that many at one time (it's limited to below the max range elsewhere). I'm trying to make the data passed around as small as possible.
I'm wondering in the general case though, if there was a lot of computation on it then would it make more sense to just use int for performance over size?
VS 2015 i thought Crystal Reports were included? DId i fuck up somehow?
>>54090711
In the general case I would always go for the default integer, cause that's what other developers expect. Choosing size of int is more of a concern when you are vectorizing your code which shouldn't be related to the size of int you are sending over the internet.
You mentioned that you want data that is passed around as small as possible, have you looked into how the packets are defragmented and that stuff?
>>54090822
Got it, thanks for the input.
>have you looked into how the packets are defragmented and that stuff?
Not yet, currently I'm letting something else manage the packets and socket while I work out the protocol, data types, dispatching, and procedures. I plan on looking at the lower end of things once everything else works well.
This is my first time doing anything over the internet so I'm pretty clueless to be honest, everything is working but I'm curious if I'm doing something egregious somewhere. I feel like it's important to do my first network program as correct as possible so I can look back on it later as a reference of what to and what not to do.
>>54090925
>I feel like it's important to do my first network program as correct as possible so I can look back on it later as a reference of what to and what not to do.
Haven't we all? But yet again months later we look back and realize what kind of shitty code we wrote.
I do that a lot atleast, with Haskell nowadays.
Focus on a structured protocol, error handling and in the case of unordered messages and the pure structure of the program. Try not to tie your code down to the sockets themself, use Object-serializing classes (proxy design pattern) as a middle man between your models and the protocol-classes.
Newbie here, I'm working on a simple python script which sends arbitrary stuff between Twitter and IRC. Right now I've got the Twitter bot working separately from the IRC bot, but I'm not sure how to combine the two.stream_listener = CustomStreamListener()
stream = tweepy.Stream(auth, stream_listener)
stream.userstream()ircbot = IRCBot("#somechannel", rand_name(), "irc.freenode.net")
ircbot.start()
These two code snippets work independently from one another, but they block one another I just run them as-is. Can anyone tell me how to combine both and run them together as a module (or whatever)?
>>54091019
If these calls are blocking then start them in separate threads?

>>54090999
Thanks for the advice. Everything was pretty simple up until the error handling part, it's not very complicated but it sure is a lot of handling just to abort things in a more granular manner.
Constantly slimming things down and reworking it to be more general is kind of fun but takes some thinking and time.

You're supposed to pass the functions to the run_parallel function, not call them and pass the return value (which won't "arrive" since they block).
So try that instead:run_parallel(stream.userstream, ircbot.start)
Although I don't know if you can do that like that with object instances, if that doesn't work, try to look for whatever is Python's alternative to C++'s std::bind.

It's a monte carlo path tracer, of course it's slow.
Could be improved by using a better acceleration structure for ray/scene intersection though. My current BVH isn't that high quality (simple binned BVH with SAH heuristic). By far most of the time is spent traversing it, so that's where most of the gains are.
And yes, there is noise, I only let it render for a couple of minutes. Eventually it should converge to a photo-realistic image. I still have to implement stratification, which will increase convergence further.
>>54090367
Iirc the sicp intro said lisp is intuitive enough that you don't need to separately learn it. Also they teach you the basics in the first few chapters
>>54089983
Cute. If I were you I'd pre-allocate the done and e_pot arrays instead of using append. You're already using enumerate so append isn't really clearer than just accessing the nth element, not to mention that it's wasteful. Also I don't really get the changing the axis parameters all the time. I mean, it only tracks two of them either way (in the default example the most boring ones) so it doesn't really make sense to waste cycles on it imo. I liked the animation.

My final project for a software design class is to make a board game, and we're doing Risk. However, I'm pretty much clueless on how to get the front-end GUI stuff working, other than a bunch of shitty buttons all over the screen.

How do I reference my ircbot object from within the on_status method here (see arrow)? I know this is wrong (it doesn't work and throws an error) but I don't know how to fix it.

def on_status(self, status):
if status.user.screen_name == bot_screen_name:
return
if status_text[0] == "\"" and status_text[-1] == "\"":
print "debug: quote text"
ircbot.pubmsg("testing") #### <----------
def main():
stream_listener = CustomStreamListener()
stream = tweepy.Stream(auth, stream_listener)
stream.userstream(async=True)
ircbot = IRCBot("#test", rand_name(), "irc.freenode.net")

A method in the IRCBot class creates a connection object called c. Connections have a method called pubmsg which simply sends a message to an IRC channel.

I've been doing pretty well in C++ class, since mostly so far we've been in the "C with classes" portion of the course and I had a great instructor for C last semester. But we just hit all the inheritance/polymorphism and derived/subclass stuff and I'm completely lost, plus my current instructor can't string a comprehensible sentence together to explain the concepts clearly enough to me.
Are there any resources you'd recommend? I prefer video lectures rather than reading if I can find them as I absorb concepts faster from an actual person than a book, but youtube is just full of Indians with atrocious accents that are about as unskilled as my instructor at actually explaining stuff.
Reading material is fine too, as long as it gets the concepts across concisely. I'm an EE, not a CS/SoftEng major, so while I appreciate the theory, I'd rather skip straight to understanding how and when to apply this stuff right now so I can finish my assignments.

or if you want equal probability of all entries being displayed without collisions, flatten your hashmap into a flat array andrand() % NUMBER_OF_ENTRIES

This is my GET request function in C being used,you can just call it and it does everythingint bufsize = lazyKB(16);
char buffer[bufsize];

I think society could still function without everyone going along with charity. The system would be able to support a certain percentage of 'freeloaders' (those who are unable or refuse to participate). Some would want to help others just because. Things would balance out. Maybe it's wishful thinking. It works on the small scale though.

is nice, I use it everywhere more generally anytime you have something likemytemplatetype<othertype> a;

mytemplatetype<othertype> c = a; //this
It's an automatic typedef, use it as such. Don't turn your code into some messy Python bullshit.
>>54094744
>It's basically a preprocessor that the compiler figures out later
>Basically a weakly typed feature
you seem to be confusing dynamic typing and weak typing. C is weakly typed but also statically typed, while Scheme is strongly typed but dynamically typed. on the other ends of the spectrum, Javascript is both weak and dynamic and Haskell is strong and static.
>more obfuscation, less readability
readability should not be focused on the internal parts of a function. in fact, if you have to open up abcdef.cpp in someone's code base and skip to line 3291, chances are that code is absolute dog shit (regardless of whether auto is used). putting types in explicitly is not a part of readability, especially when it comes to huge template types that "obfuscate" your code even more.
>>54094988
type inference has nothing to do with dynamic typing other than surface syntax. in C++,whateverhas a type that it is type-checked against at compile-time. in javascript, the variable just takes whatever value makes sense in the context and never gets type-checked ahead of time
how would you sort a list inside a list. for example if you had a list of odd numbers 1, 3, 5, 7 and a list of evens 2, 4, 6, 8
List<Integer> odd;
List<Integer> even;
numbers.add(odd);
numbers.add(even);
Collections.sort(numbers);
so that the sorted list is 1, 2, 3, 4, etc. but what if you want to sort even numbers within the sorted list so that the result can be something like 1, 8, 3, 6, 5, 4, 7, 2. how would you do this efficiently
can someone explain vTables to me? to my understand (correct if im wrong) but it's a table that a base class will have if it has member methods marked virtual, and derived classes will have it they then overwrite that parent member method. the vTable then basically contains a pointer to the derived class's new, overriding member method?
>>54095081
>Messages come back through a wrapper implementation class.
Okay, I think I understand your problem better now. So if I'm correct, you're connecting to this stock API through this wrapper, and you want your UI thread to reflect these changes when that occurs.
Are you using WPF? You can use INotifyPropertyChanged to implement this behavior with data binding. You might want to look at the MVVM pattern if you're not doing so already.

Seeing if I can prove that philosophy is horse shit using a markov text generator. I had it read philosophy books and made a few weighing functions to determine what the optimal output is. See if you can determine which is a quote from German philosopher Immanuel Kant, and which is the robot which learned to speak by reading Immanuel Kant's works, without googling either quote. Then check yourself to see if you were right:
>[...] apply a priori to objects, the transcendental deduction of conceptions, and I distinguish it from the empirical deduction, which indicates the mode in which conception is obtained through experience and reflection thereon; consequently, does not concern itself with the right, but only with the fact of our obtaining conceptions in [...]
>[...] and dry, as the brain; and that everything which the understanding estimates distance, it thus happens that in both cases the quantity reference throughout to the limitations of its own free will. The close connection of the concept-spheres in order to pass over to thought, [...]

subclasses have a table of pointers to their implementations of virtual functions
objects of that subclass have a pointer to that table

>>54095304
you really don't need to know how vTables work. basic knowledge can help make sense of vTable errors I suppose, which is probably why you're asking, but solving enough of those errors and/or reading on how to do things the correct way will accomplish the same feat.

I have 3 nested lists that all have two elements in each minor list, like this:a = [[1,0],[2,1],[4,1]...
a is an Ax2 matrix, b is Bx2 and c is Cx2. In most cases A=B=C but not always. any sn4kelyfers on that know a nice way to write this to a file so the out put looks something like:a00,a01-b00,b01-c00,c01
a10,a11-b10,b11-c10,c11

the "-" isn't necessary, it can all be commas or whatever.

I think I may have made a mistake becoming a programmer.
I'd rather write stories than maintain servers and shit like that. Game dev would be an option if it weren't for the fact that I can't get job in the industry without making a game of my own first. Naturally I blew the one opportunity I had by making a collaborative code editor instead that doesn't work and now I'm going to have to devote my life to something I have no passion for
>>54095842
dude, are you serious?
assuming you're using a language with dynamic-length strings, this is pretty damn easystr = "";
max = max(A, B, C);
//an IxJ matrix only goes up to I-1 and J-1
for (i = 0; i < max; i++) {
if (i < A) str += ai0 + "," + ai1 + "-";
else str += ",-";
if (i < B) str += bi0 + "," + bi1 + "-";
else str += ",-";
if (i < C) str += ci0 + "," + ci1 + "-";
else str += ",\n";

Of course macros in other languages are more powerful, but what I find great about C macros is that you can "expand" the language far more than you thought. Lisps are expected to do all sorts of crazy things, C, not so much. (in this scenario)
