What are you working on, /g/?

first for my wife's son java books
Delete that slut and make a new thread with 2D immediately.
I have a quick C++ question. New to modern standard and confused, don't know how to google this properly.
I have an object of type A with 5 data members. Object B has a member of type A. I want a function to pass a new A to B to refresh that member in the most efficient manner possible. Here's what I have:inline void B::refreshA(const A& _a) {
a = _a;
}
and wrote the copy assignment operator of A as:inline A& A::operator=(const A& rhs) {
m1 = rhs.m1;
...
m5 = rhs.m5;
return *this;
}
I don't know:
1) If I should be returning an A in the operator= or A&.
2) If I should be using moves somehow, not copies.
3) If I should be doing copies if I even need to write this copy assignment operator as I'm pretty sure I just wrote the default generated one.
Am I the only one who read <stdio.h> as studio and not standard input output for years?
>>53847663

>>53848122
Nah. Matz and his brethren really are nice.
>>53847663
No, but for the first year or so of knowing C++, I thought cout was pronounced "koot", and cin was pronounced "sin". Then I heard someone pronounce it "see-out" and everything made sense.
>>53848367
oh yeah koot
Babby-tier question, but is doing something like valid/good practice?#define COLOR_CORNFLOWERBLUE 0x64, 0x95, 0xED, 0xFF
...
SDL_SetRenderDrawColor(myRenderer, COLOR_CORNFLOWERBLUE);
>>53847642a = _a;
Calls the assignment operatorm1 = rhs.m1;
Either calls assignment operators for m1 or deletes the old m1 and calls the copy constructor for the new one.
Typically if you wanted to move things you would write a move assignment constructorA& A::operator= (A&& rhs) {
And you would call this withvoid B::refreshA (A&& _a) {
a = std::move(_a);
}
which would take all the memory resources out of _a and move it into a.
You don't need to move things if the members are just primitives like int/bool. It's nice to move std::vector<>s or std::strings if you want to conserve memory but C++ is pretty fast so if the data structures are small then copying is fine.
Recently I've been writing my methods likevoid foo (A a) { // fuck references
...
}
int main () {
A a1 = ...;
foo(std::move(a1));
// a1 no longer usable
A a2 = ...;
foo(a2); // implicit copy
// a2 still usable
}
This way the caller gets to decide if the memory is moved or copied. This gets annoying in some cases where it can't decide overloads, I can explain if you'd like.
>>53848367
>koot
Are you fucking daft?
Cow-t
>>53848571
Probably not. The "correct" way would be to have a helper method that you pass a single data type into.static void setRenderDrawColor (void* r, uint32_t color, uint8_t alpha) {
SDL_SetRenderDrawColor(r,
color >> 16,
(color >> 8) & 0xff,
color & 0xff,
alpha);
}
setRenderDrawColor(myRenderer, 0x6495ed, 0xff);
>>53848571
Seems limited. Might be better to wrap the functions in other ones so you can pass around 'Color' structs.

a girl from my operating systems class just convinced me to email her my entire program's source code. when she asked i said no because the professor gives you 0 if he finds you cheated, and that i would just send her the resources i used instead, but then she said she was just going to use it to see what we were supposed to do and how it worked. so i felt like an asshole. i feel so taken advantage of. i spent like 3 days working on that program.

>>53848581
>This gets annoying in some cases where it can't decide overloads
I know what you're referring to, I need to review that but know where I can find the info.
here's my thing:
A has four floats and a scoped enum as members.
My old C style wants to just model it as a C array of size 5 and then I could just pass the pointer.void B::refreshA (float* _a) {
a = _a;
}
Thats the kind of efficiency I'm looking for but then I'm modelling my enum as a float and its gonna get weird after that. If I usevoid B::refreshA(A _a) {
a = _a;
}
int main() {
A a1 = ....;
b.refreshA(std::move(a1));
}
Is that the same thing behind the scenes or is it going to do member wise move for each member of a?
This code is being used in a critical part of a loop in some performance intensive code that I'm trying to refine.

Anybody work with reading directly from URLs before? I was reading it up on Java Tutorials, but the example is confusing as hell.
I browsed the java.io API to see useful classes for reading HTML files to filter out strings that begin from one HTML tag and end at another.
For example, a text string beginning from: <div id="thread-53847372" class="thread"> and and ending at </div>.

Yeah. I think I can find the content between the tags by using a glob pattern, either with the dot (.) or (*) wildcards.
The example Oracle provides just doesn't make sense to me, though. They use this BufferedReader constructor to read the URL's contents after creating the URL object.

Please don't tell me you want to parse HTML with regular expressions. Please.
>>53852287
What's wrong with that? What's a better alternative?
>>53852301
HTML is not a regular language. If you want to extract one very specific thing you can probably get by but don't parse full on HTML with regex, it's impossible.
Try a HTML parser library if you need that
>>53852287
>Please don't tell me you want to parse HTML with regular expressions.
If it's a small bit of HTML that will likely remain the same, it's probably not a big deal.
>>53852301
You can't parse [X]HTML with regex. Because HTML can't be parsed by regex. Regex is not a tool that can be used to correctly parse HTML. As I have answered in HTML-and-regex questions here so many times before, the use of regex will not allow you to consume HTML. Regular expressions are a tool that is insufficiently sophisticated to understand the constructs employed by HTML. HTML is not a regular language and hence cannot be parsed by regular expressions. Regex queries are not equipped to break down HTML into its meaningful parts. so many times but it is not getting to me. Even enhanced irregular regular expressions as used by Perl are not up to the task of parsing HTML. You will never make me crack. HTML is a language of sufficient complexity that it cannot be parsed by regular expressions. Even Jon Skeet cannot parse HTML using regular expressions. Every time you attempt to parse HTML with regular expressions, the unholy child weeps the blood of virgins, and Russian hackers pwn your webapp. Parsing HTML with regex summons tainted souls into the realm of the living. HTML and regex go together like love, marriage, and ritual infanticide. The <center> cannot hold it is too late.
...
>>53852196
>mind blown
does that work if you want a non-const iterator too?
...
The force of regex and HTML together in the same conceptual space will destroy your mind like so much watery putty. If you parse HTML with regex you are giving in to Them and their blasphemous ways which doom us all to inhuman toil for the One whose Name cannot be expressed in the Basic Multilingual Plane, he comes. HTML-plus-regexp will liquify the nerves of the sentient whilst you observe, your psyche withering in the onslaught of horror. Rege̿̔̉x-based HTML parsers are the cancer that is killing StackOverflow it is too late it is too late we cannot be saved the trangession of a chi͡ld ensures regex will consume all living tissue (except for HTML which it cannot, as previously prophesied)

Still fucking around with vulkan, now I have to figure out how to draw vulkan shit in a win32 window.
So I took a class that taught all about the basics of OOP and used Java.
Where can I go from here?
I tried practicing some coding with C++ but apart from some basic syntax differences it feels almost the same. What's the big difference here?
What's the best option to take on from here?
Can I extend my knowledge of Java to using Android Studio and create Android apps now?
Or should I focus more on C++ and try web development through Visual Studio (and learn vb.net)?
What's the typical "next" step for someone learning to program who might hopefully use these skills in the workforce?
Any help would be appreciated.

get a good C++ book and read it from cover to cover then read the C++11/14 docs to see what they added then get a good book explaining all the C++11/14 nuances, like Scott Meyers latest book.
You fucked up learning java first, all you really know is object oriented concepts and potentially basic OOP design.

I've been reading some computer vision papers that tend to devolve into intense math equations and weird terms that make little sense. Other data science papers have the same trend.

>>53853268
I mean, I just learned it that way because it was the way my university teaches it, and we've made a lot of interesting programs with Java.
So learn C++. What, then, should I do with it? Is web development the best option?
What about Android App development? Knowing Java should enable me to make the leap to Android App development, yes?
>>53852941
C++ has things like template metaprogramming, RAII + smart pointers, move semantics, lambda expressions, etc., all of which give C++ a powerful suite of abstractions that don't significantly penalize performance.
>>53853350
function calls destroy the notion of C++ free abstraction
When will I get good at Unity? i've been doing the tutorials several times but it takes so long. I only grasp some of the basics. Are there better ways to learn Unity? Or am I being a weakling?
>>53853364
My wording was careful. I said
>don't significantly penalize performance
Yes, there is often a small performance hit for these abstractions, but the gain in convenience is almost always worth it. Besides, you can spend the extra development time you save to micro-optimize and get faster code than had you used, say, C. qsort is an example of how these abstractions can result in faster code.
Once I know C++ and Java, what should I do with it?
Is web development a good path to go down for C++ programming?
And for Java, I can move on to Android App development, yes?
>>53853319
>what do I do with it
whatever you want.
The big thing about C/C++ is the memory management is up to you. That is you have to control when physical memory (RAM) is taken and freed by your program. Recent to not so recent standardized features in the language can make this a lot easier but it's one of those things where if you don't start from square one getting to square n will be a lot harder and confusing.
If you're a student its good to use this time to learn a variety of languages and try doing different shit with them. Don't expect every project you make to make you the next Zuckerberg, focus on learning and do what you want to do.
Android App dev is done in Java, yes.
>>53853378
You need to actually build on the tutorials yourself and play around with the documentation to figure out stuff
>>53853400
Come up with some projects and make them.
What else would you do?
>>53853400
web dev and C++?
boy
>>53853399
C++ doesn't just need a guaranteed inline specifier for functions, it needs one for structs and classes too - and it should be available at the call site AND the callee.
>>53853400
App development is one path. C++ is increasingly being used for mobile apps because both iOS and Android have an C++ SDK, meaning that you can write the core of your app in C++ and it'll be portable between the two OSs, and leave the GUI stuff to Swift and Java respectively. If your app is performance critical (like a graphically intensive game) you'll also want to use C++.
Web development is another possible route. C++ is used in high performant servers (Google for example makes extensive use of C++).
Both are very versatile languages that won't limit your career path.
>>53853445
by inlining a struct/class I mean this:
template <typename T>
inline struct pair {
T first, second;
pair(T a, T b) : first(a), second(b) {}
}
pair<float> x (3, 4);
->
float x_first (3.f), x_second (4.f);
(some mangling for . / _)
>>53853445
>it needs one for structs and classes too - and it should be available at the call site AND the callee.
I don't understand. If you inline your constructor, doesn't that accomplish the same thing?
>>53853470
not necessarily & inline in C++ is just a hint
I mean inline the whole thing
C++ really just needs a proper macro system with strong CTFE

Not really. Assuming there is a minimum IQ to programming irrespective of gender, there are less men capable of learning it.
How do I get started in AI? It's what I've wanted to do for a while.
I know C, Python ish, C++ ish, whatever. Where do I begin from scratch in AI? Norvig?
>>53853488
are you actually looking at what your compiler generated to support your "its just a hint" meme?
I've never had issues with reasonable functions not being inlined and using modern g++ you can see functions that weren't explicitly inlined actually get optimized to be inlined.

well inlining is necessarily implementation dependent so you have to trust your compiler. you're bitching about something thats not really an issue.

> best way to model dates in C++?
> Will just be doing basic subtraction and comparisons with them.
In which case, you want to store linear time (i.e. a number representing the amount of time elapsed since some epoch) and convert to/from calendar time (year, month, day, hour, minute, second) as needed.
For linear time, you can use <ctime>, <chrono> or boost.date_time. For calendar time, <ctime> or boost::date_time.
The conversion between linear time and calendar time is complicated by time zones, leap seconds, and synchronisation ("system" time may be slightly faster or slower than real time in order to synchronise with an external time reference, which is why <chrono> has system_clock and steady_clock).
>>53853673

> I mean inline the whole thing
You mean make every member function automatically inline?
It's not like you can "inline" data.
>>53853728
I mean act as if there were never any struct in the first place
>>53853728
>>53853741
Like, put declarations directly into the scope with a mangled name like
x_m1 (for x with member m1)
the syntax would be the same, x.m1
all calls to functions would be replaced with the inlined body referring explicitly to in scope variables
>>53853755
There's no difference. x.m1 does not involve any indirection, so it is the same as reading the value of a variable.
>>53853800
inlining the struct would make all the member functions forcibly inline
>>53853686
>started writing my own basic calendar time wrapper to support my basic functions after my post.
>realize all this would be 1000% easier if we didn't have months and added leap years to the beginning of the year or the end of the year
Working with dates is way too complicated for how simple they are. Why the fuck do we use a 2000 year old system that has only been modified once by a dude who unironically wears pic related.
>>53853806
You don't necessarily want that. Your compiler knows better than you whether a function should be inlined.
>>53853838
Not always, and it'd be nice if we could make the compiler put the functions together first and then decide how to split them up, especially with function composition
>>53852032
Just do it in python with beautifulsoup or c++ with rapidxml

Mainly working on a Python IRC client and ignoring my Java schoolwork.
I have to use JSF for a project at work. I swear that JSF is the dumbest framework I've ever used. It's "component based" rather than using request-response. The idea is to try to make it easier to manage state over a session. The problem is that JSF's lifecycle model is so fucking complex with so many little intricacies that it actually ends up being harder to understand and use. I think the only person in the world who truly understands it is BalusC (every JSF programmer will recognize that name). The second problem is that you have no idea what kind of HTML will actually get generated. Want to create a simple hyperlink? Here's some Javascript to go along with that. Want to output a message? Guess what, it's getting wrapped in a table tag even though you never specified that. Oh, I see you put "myelement" for an id. Let me just change that to "j_124" so that your CSS and Javascript break.
Everything in JSF feels like an ugly hack. Want to validate user input for a form field? No problem. Want to do validation that requires examining two fields (example: checking if the confirmed password field matches the password field). Sorry, JSF can't do that without resorting to ugly, convoluted hacks to work around it. The way JSF works reminds me of Maven in that the base cases work okay, but if you want to do anything slightly outside its domain of acceptable functionality (even things that are considered quite common), then you have a fucking mess on your hands trying to get it to work.
Don't even get me started on the verbosity of JSF. Look, I'm a Java programmer. I'm used to verbosity. But JSF makes other Java code look downright fucking concise. Whenever you see a call to "FacesContext", you know that you'll be reading a short novel's worth of method chaining just to access something trivial. OmniFaces can make it a little more tolerable, but not by much.
