I want to start working on actual projects instead of short scripts. Which should I do first? Contribute to existing free software projects or start my own?
I'm not that experienced at programming but wouldn't consider myself a noob either.

>>51606893
Find something you wish existed and make it happen.
In order to contribute to existing projects, you need to read the source code and gain a good understanding of how it's structured before you go pull requesting any changes.

I'm really enjoying Processing.
What are some libraries that are just fun as fuck at what they do?

>>51606945

isn't that that liberal arts psuedo-programming language designed to trick liberal arts majors into thinking they actually learned something at their $50,000 a year day cares?

>>51606945
ew

>>51606922
Anything that I wish existed is probably too large of a project for me to start with.

I know I need to understand how existing projects work first. The problem is finding a project that's small enough that I can make a reasonable impact on AND large enough that it's actually useful software.

Any tips for the Java OCA exam?

>>51607176
so you're just gonna keep living a lie then?

Java pleb here, working with GUIs and timer for the first time. I have a simple program that moves an image/label at a certain period of time everytime a button is clicked (jrb1 and jrb2)

But I don't understand. If I click jrb2 (makes the image goes faster) and then click jrb1 (makes the image goes slower), the timers add up (probably because a new timer object is made each time?)

Any good advices /g/? Is this a bad approach for a program that moves images around in a frame?

 public void actionPerformed(ActionEvent ae)

                 {

                      // Move the object randomly, subtract 75, so that the

                      // object should not meet the edges

                      lb.setLocation(r.nextInt(getWidth() - 75), r

                               .nextInt(getHeight() - 75));

                 }

             }).start();

         }

         if (jrb2.isSelected())

         {

             // Create Random object

             r = new Random();

             // Create a timer and call it for every k seconds

             new Timer(750, new ActionListener()

             {

                 public void actionPerformed(ActionEvent ae)

                 {

                      // Move the object randomly, subtract 75, so that the

                      // object should not meet the edges

                      lb.setLocation(r.nextInt(getWidth() - 75), r

                               .nextInt(getHeight() - 75));

Sure, tarball coming up.

In C#, imagine I have two tightly classes coupled together. Say, a flowchart block, and a slot for flowchart block that allows to collect blocks together.

As I expand functionality, I always have to, after observer compiler errors, come back to fields I added to these classes and put "public" in front of them.

One of the solutions I learned for avoiding this is to put one of classes inside another.
Is it the only one, or are there better?

Stupid question, but I'm new to C++.
If I want to read text from a file and save it to three different variables how would I do that?
Say I have a text file like this,

DICKS (2, 1)

How do I get C++ to read that line and dump "DICKS" into a string, and the two numbers into separate integers?

I'm trying

string key = "";
            int x = 1;
            int y = 0;
            [spoiler][/spoiler]
            ifile >> key >> x >> y;

but it doesn't seem to work. The output is only ever,

DICKS (0, 0)

>>51609535
No idea how that spoiler tag got there, ignore.

>>51609535
write a tokenizer, it doesn't work because you're trying to save space and ( to the integers probably

>>51609535
Not sure if C++ would be too different, but in C I'd tokenize the line with strtok(). Use " ()," as the delim and then NULL for each call after the first; strdup() for DICKS, atoi() when the strings that are to be integers.

>>51609995
It does require something different. Classes are for objects, structures are not. It doesn't matter if structures have capability to act like classes. They are different things made for different stuff. BTW, the reason you can use structs as classes is because of compatibility with C(I think).

/dpt/ I'm working on a visual novel section of my game, and I'm having trouble thinking of a good implementation as the states are event based so the whole 'one big function with wait for input' option isn't ideal.

What I need is a way to store segments of the story (add/remove characters from scene, write to text box, etc) which can then be iterated through after pressing enter/space.

So far I can only think of making a small callback like struct, hardcoding each segment and then adding them all in order to vector/list and iterating through on input, but it seems clunky.

Anyone have any suggestions?

Python sound's like it should appeal to the 7 year old 'who we have to teach programming!' Ruby too desu

>>51610102
Make a n-linked list so you have a series of structs(possibly from a external file, or hardcoded) and they are linked together by pointers for the options.

I have a java interview tomorrow,i had to do a function that takes a string ,does some calculations with it and returns a new string and also add unit tests.
I've done the requirement but heres the problem.
I've done the main function(the one that takes the string) and some auxiliary functions for each step of the problem and added them to the main function.
All my variables are in the functions,so i have no fields.
What is the best practice?
For example:Lets say you have to make a function that takes a car name as String ,does some calculations and then returns the result as String.
For me,i put all the steps of the function in auxiliary functions who i then call in my function in order to process the String and return the processed String.

There really is nothing redeeming about Java these days. If you actively choose to use Java in personal projects, then you simply don't know many languages. This is invariable.

auxiliary function2(){

Result = auxiliary function2(s);

return result;

Something like that.
The main function definition is given by them,i just gotta implement it to return the requirement.
All the work is done in the auxiliary functions that at their own turn have 1 or 2 auxiliary functions to further divide the problem for readability purpose.

If you are using them very often, then you are an idiot.

Also, check the benchmarks.

>>51610675
>why are you not posting actual code
This is the structure of it.
I cant obviously post code as they will search for it.
Its 1 mainfunction and 2 or 3 auxiliary functions who split the problem and that process the given string(and some of them call other auxiliary functions too) .
Its an algorithmic problem.(not like open some binary file ,read first lines and output the result).

>>51610701
>others don't.
I recall Oracle suing the shit out of Google for using Java API's.

I don't recall MS ever doing anything to Xamarin who make millions off selling their mono driven iOS and Android dev tools and runtime. Or anyone else for that matter. They also made a legally binding promise that they will never do so to any company that does the same thing.

I also recall Oracle threatening to sue companies who reported security issues in the JVM.

You put some nodes on the windows, the system passes objects between them, at the end of all this you get a 2d map you can export to disk in some some format you choose.

>raw pointers
Whenever I want to use a native library in my C# code. Which is every now and again. Incredibly useful feature to have. The best part is, is that native library wrappers are a cinch to write in C# compared to Java. So they are very easy to come by for most things. There's two 100% complete API wrappers for DirectX for example. And at least one for OpenGL.

>unsafe arrays
I've used these a couple of times for messing around with image manipulation. Something Java is really not suited to at all.

>>51610741
how often do you write Java code that does that?
oh right - you don't
because java can't.

features that allow you to get the best performance out of a language are quite critical when you have a large project in that language, as you don't need to write a specific module in a different language only to get that performance, leading to lowered maintainability.

>If you are using them very often, then you are an idiot.
agree with you on this, if you need high performance mission critical code, then you'll probably be writing it in C, or even lower. C# has great C interoperability though, so that's perfectly ok.

>>51610791
>Where is the extinguish?
they are only alive today because of other open source ventures saving them, e.g. apache for openoffice.
everyone knowledgeable has dropped mysql for mariadb (literally, as mariadb is a drop-in replacement) because of Oracle.
Oracle makes Oracle Database, the proprietary db. Since they also govern mysql, you can see they have a conflict of interest.
Making mysql faster than OracleDB would cause them to lose money, so nothing extreme can be done to the project. MariaDB has no limitations.

C# is better than Java just because of the sane type system. Forget about boxing. Generics done without hacks. Etc. And extension methods, oh my god, why no other language provides it.

>>51610799
I don't write them in Java, because I don't need to. There are enough large projects out there that use only garbage collectors and safe arrays to prove that those are not required features for most of the projects. At least for the projects Java targets. Hell, if the performance is so critical that you are gonna care about array bound checking, why would you use a language that runs on a VM?

>>51610848
There is still the fact that no extinguish happened.

And also what's more important is that EEE works to destroy standards, not products. So the situation you're describing with Mysql not only not happened, it also is not EEE.

>>51610864

I *LOVE* both of them. Java is wonderful, and C# is wonderful too (except for potentially being a trap). Both Java and C# have amazing IDEs.
I also kind of like C++ with Qt extensions. C++ by itself, is, well, I used to hate it (ever since I discovered C), but I grew to accept it.
I also love Perl. Everything small that needs to be written quickly, I do in Perl.

You love everything, Bob. Have you been smoking weed lately?

>>51610895
If your question is, is writing functions like that acceptable, then the answer is yes it is.

If auxiliaryfunction1 and auxiliaryfunction2 are not used anywhere else in the project, creating them might be a bit counter-initiative, the way I see it, because the person who's going to be maintaining your code will have to jump around for no reason. The only reason to have them, in this situation, is, I think, when their names very well reflect what they do, so the person who's reading them won't even have to read them.

So this would probably be good:

function findUppercaseWords(text){
    var words=splitTextToWords(text);
    var result=retrieveUppercaseWords(words);
    return result;
}

And this wouldn't:

function findUppercaseWords(text){
    var x=aux1(text);
    var y=aux2(x);
    return y;
}

>>51610940
Why is it impossible to like both?

>you act like java doesn't have opengl wrappers.
I'm not acting like that at all. That would be you desperately looking for ways to defend java. I'm well aware Java has OpenGL wrappers. My point is that kind of shit is much harder to created. Even more so with the lack of pointers, structs and fucking unsigned integers, that would make native interop much more intuitive.

>JNI is very easy to use with jnigen
.NET has wrapper generators too. They just don't need to be so complicated as Java ones, and you don't need to use them as much just to pull in a simple function from a native library.

>>51611042
Does C# have the ability to pull functions out of Linux's .so libraries?

>>51611006
yes,all the auxiliary functions are only called once but their names reflect what they do.
So i have a mainProcessingFunction which takes a string to process and that which just calls the 2 auxiliaryFunctions on that string i have and returns the result.
But one of the auxiliary functions has 2 algorithms inside it,first one that puts the received string in the proper form first and 1 that processes it.

Well, that invalidates your point a bit, doesn't it? All the stuff that's so easy to use in C#, turns out only to be only easy on Windows, making it increasingly more difficult to use a different operating system, and those are exactly the concerns I expressed when I was mentioning EEE.

>All the stuff that's so easy to use in C#, turns out only to be only easy on Windows
I'm not really sure what you're talking about. I'm not sure how GTK# imports the GTK native libs, but that doesn't suddenly mean it must be difficult to do.

importing .so files is easy. see: http://www.mono-project.com/docs/advanced/pinvoke/

I'm not sure why i can't see it in GTK# though. Maybe they so something else I'm not familiar with.

>>51611430
one possibility is that DLLImport is not needed for mono on linux, since GTK# is a core library there and the mono runtime can pull in those libraries behind the scenes.

>>51611459
I'm not going to learn java first, I want to learn C first.

>>51611430
So this essentially means that any program that uses DllImport to get native Windows stuff is not going to work anywhere but on Windows. You see this as an advantage, but in my eyes, Java makes it less easy to become dependent on operating system, and C# makes it very easy, and that definitely is not an advantage.

>>51611468
I'm not saying it's easy. I'm just saying it exists.

>>51611489
>So this essentially means that any program that uses DllImport to get native Windows stuff is not going to work anywhere but on Windows.
That's not in any way correct.

>Java makes it less easy to become dependent on operating system, and C# makes it very easy, and that definitely is not an advantage.
I think it is in fact an advantage m80. Native interop a hugely useful feature. Making it needlessly painful to do it is stupid. Note that it IS possible to do it in Java, it's just 10x more work. So doing a cross platform wrapper for a native lib for Java is 10x more difficult than in C#. Also in any event, the programmer get's to choose the trade off of how cross platform his application is. Obviously it's easiest and most encouraged to avoid DLLImport unless you really need it. If you really need it then you know you'll have to do it for each platform you run on. It's up to you if this is worth the time and effort or not. You have this problem in both Java and C#, but in C# it's much easier to do both platforms.

that's what you think. one of these days, you're getting kicked out like rage comics got kicked out.

Imagine you're writing a libary called ABCD.
All your objects are defined within an ABCD namespace right?
What if you then create a subsystem called EFG?
Should objects within EFG be accessed with ABCD::EFG:: or just EFG::?
ABCD::EFG is too long, and just EFG implies EFG is not a part of ABCD.

>>51612171
Is EFG nested inside ABCD? If so, if you're outside of the ABCD namespace, you can access the members of EFG only with the full path ABCD::EFG::

>>51612321
>Is EFG nested inside ABCD?
That's what i'm asking.
EFG and ABCD both need eachother.
Outside of ABCD yeah you can use ABCD::EFG but that's a bit too long.
I also just remembered the user can just create a namespace alias so that's no longer a problem.

>>51610639

I'd say this should be handled by the consumer of your library; it is their choice.
most languages have a 'using' keyword which allows you to choose the shorter version or fully qualified version.
