good news boys, only took me 3 hours but i got java up and working with notepad and command prompt. turns out you just need to save as "filename.java" and add a new environment variable called PATH with the location of jdk's bin. now i can be nice and comfy all semester without having to fuck with learning how to use an IDE

>>52391889
impressive, how did you go about doing it?

>>52391946
I basically just manually took an RGB value from each block type that exists in pi edition, and then I went through the image pixel by pixel, and compared the pixel's RGB value to each available block's RGB to get the closest color match.

I tried to ask in a /sqt/ but got no answer, so I'll try here.

I bought SICP and want to write code and test ideas as I read through it. Is it reasonable to do this with C/C++, or will it be a nightmare unless I do it with LISP? I'm a professional PHP webdev so I can code and setup an environment for whatever, but I wanna up my game and potentially shift to software deving.

>>52391746
THAT'S NOT MAKI

>>52391996
some of the information may be okay to translate, but it will definitely be a challenge trying to do it with C/C++. I'd follow along with a Lisp or at least something about as high-level as Lisp.

>>52391996

I think you'd need LISP, as C/C++ doesn't expose it's AST directly. You'd have to disassemble a compiler to see what the high level symbols resolve to.

>>52392033
>>52392035
Thanks. Will Lisp be a good language to get under my belt for professional purposes? I'm reading the book to get some serious core ideas into my head, but I'm not sure there's much market for Lisp developers. Basically; should I focus on Lisp heavily or just enough to understand the topics and examples in the book?

Haskell's core feature is laziness. Every other design decision is a consequence of lazy evaluation.

>>52392106
LISP is completely irrelevant.

>>52392122

Why?

>>52392106
will you get a job working with Lisp daily? probably not, but there's a lot you can learn from it and apply your knowledge to. working with Lisp helps you with pretty much anything involving domain specific languages or metaprogramming (meaning macros, preprocessors, etc.) just reading SICP will help you pick up on a lot of that knowledge, so even if you don't work your ass off to learn Lisp and use it everywhere you can still get most of the good stuff out of it.
>>52392107
maybe, but the rest of the language could be made strict without much consequence (although I'm not sure whether that means that Haskell would have been very similar had it originally been made as a strict language (with similar ideas in all other aspects) ).

is the compiler playing tricks on me? like how multidimensional arrays are actually just one contiguous array in memory? speaking of multidimensional arrays:

int fug[5][10];

how does the compiler know where fug[4][x] is in memory? does it calculate the size of the array's data type and increment the index (4 * x) * sizeof(int)?

am i even asking the right questions?

>>52392769
lel, don't arrays start from 0?

>>52392830
I have it set so the array on the C side just contains a number ID, and a function keeps track of available numbers (starting from 1).

That way, C has lua call entity[ID].

>>52392893
Welcome to the fold.

I haven't begun refining/sorting it yet to make it look nicer, but here is 1 individual object in the lua script

objTest = { 
    ID, 
    offset = { 
        x, 
        y
    }, 
    physics = { 
        xs, 
        ys 
    }, 
    hitbox = { 
        x, 
        y, 
        w, 
        h 
    }, 
    grounded    = false, 
    dir            = 1 
} 

function objTest:new() 
    self.hitbox.x = self.offset.x; 
    self.hitbox.y = self.offset.y; 
    self.hitbox.w = 16; 
    self.hitbox.h = 16; 
end 

function objTest:update( dt ) 
    
end 

function objTest:draw() 
    SCR_DrawRect ( self.hitbox ); 
end 

C calls these functions to run the object

function EntityAdd ( objtype, ID, x, y ) 
    if _G[objtype] then
        entity[#entity+1] = entityMT:import( objtype ); 
        
        entity[#entity].ID = ID; 
        entity[#entity].offset.x = x; 
        entity[#entity].offset.y = y; 
        
        if entity[#entity].new then
            entity[#entity]:new(); 
        end 
    end
end

function EntityUpdate ( ID, dt ) 
    if entity[ID].update then 
        entity[ID]:update( dt ); 
    end 
end 

function EntityDraw ( ID, dt ) 
    if entity[ID].draw then 
        entity[ID]:draw(); 
    end 
end 

with the entity structure being

function table.shallow_copy(t) 
    local t2 = {}; 
    for k,v in pairs(t) do 
        t2[k] = v; 
    end 
    return t2; 
end 

entity = {}

entityMT = {}
entityMT.__index = entityMT

function entityMT:import( objtype ) 
    local newObj = table.shallow_copy( _G[objtype] ); 
    self.__index = self; 
    return setmetatable(newObj, self); 
end 

What am I doing wrong on the lua end? I do not believe it is the C end that is messing up. Also, can't I just put the entity functions in the table itself?

>>52392714
Python is not a good "stepping stone" language. If you want to actually learn programming and not just python, you need to learn with a language that does not hide everything from the user like python does. The abstraction in python is horrible for new programmers because they are not learning anything about programming, they do not know how their code works or what it does. It also encourages heavy usage of 3rd party libraries, which is bad for a similar reason. "Copy and paste this and then type 5 lines of your own" is not teaching a new programmer anything. If you want to just learn python to make cool meme programs like generic 4chan image scraper #54255328 without actually understanding what your code does or how it works, then go ahead. If you want to learn to program you do not start with python, period. Encouraging new programmers to start with python is stupid.

>>52393091

but jumping straight into low-level programming leads to an endless procession of questions like this >>52392809

i'm hoping eventually i will come out of it with a better understanding than if i had just jumped into python, but the journey seems a bit harder -- which i guess probably isn't necessarily even a bad thing

>>52393123
You're going to find it harder trying to learn something like a C language coming from python than you would learning it from scratch, because you not only have to learn the new language from scratch (Your python knowledge will be 99% inapplicable), you're also going to have to unlearn bad habits that python has taught you. Python is its own thing, you don't learn stuff that helps you program in other languages in python.

>>52393150

>>52393163

how many people who are python programmers will ever realistically need to learn a lower-level language though? unloaded question, by the way. curious

>>52392809
your calculation is wrong but otherwise you are correct. (it should be (10*4+x)*sizeof(int)) there are 50 ints in total, grouped by 10. fug[4] begins from 40.

i forgot to quote you in it >>52393000

>>52393209
Well, that's the thing. Like I said, if you just want to learn python then that's fine, but python doesn't teach you how to program - it just teaches you how to python. If you want to really learn how to program then you should be learning a lower level language.

>>52393163
Can you give a specific example of code or a coding style in Python that is not supported to C?

>>52392809
> why does this work?
The compiler overlooks the fact that you forgot the braces.

> how does the compiler know where fug[4][x] is in memory?
(char*)fug + (4 * 10 + x) * sizeof(int);

Given
> T a[N]
&a[i] is
> (char*)a + i*sizeof(T);

"Multi-dimensional" arrays are just arrays of arrays, i.e. T is an array. Indexing a multi-dimensional array means that "a" is itself an array-subscript expression, so the compiler just applies the rules recursively.

>>52391746
>picture

Oh shit, emacs open PDFs

>>52393229
That's nonsense. Programming in any language teaches you how to program. Some of them are more likely to make you learn certain concepts than others, but that's really not that significant.

>>52393236
Well, all of it's "possible" if you don't mind writing a large chunk of what's basically a Python runtime first.

But most idiomatic Python is a long way from idiomatic C. E.g. in C you tend to go to some effort to calculate array sizes up front so that you don't have to keep resizing as you go, have the caller create an array which the callee populates, etc.

Java a shit

>>52393316

It would be a pretty shitty operating system if it couldn't open PDFs.

>>52393249
>(char*)fug + (4 * 10 + x) * sizeof(int);

the compiler casts the array index to a char pointer? that's pretty cool, didn't even know you could do that.

>>52393365
fug is an int pointer. int* + x actually compiles to value of pointer + x * sizeof int. he casted it to char* so it 'x' wont get multiplied

>>52393209
> how many people who are python programmers will ever realistically need to learn a lower-level language though?
It depends upon your threshold for "Python programmer".

If you include everyone who did a ten-hour Programming 101 course at their local college, then not many.

If you mean people who're likely to actually do significant work in Python, then a large chunk already know C or C++ and a large chunk of those who don't will eventually learn it for some reason or another (the main exception being web devs; unless you're employed or contracted by the web host rather than the client, you typically don't get to use languages which compile to native code).

>>52393365
The cast to char* is just so that everything is in raw (byte) addresses.

>>52393249
>The compiler overlooks the fact that you forgot the braces.

looks like i was overcomplicating everything. for some reason i assumed that the array initialization was somehow skipping over the struct referencing(dereferencing?) and directly initializing the struct's members contiguously in memory, if that makes any sense. i think it was because the syntax was the same as you would use to initialize a normal array of a basic data type. doesn't make shit for sense in retrospect. anyway, thanks

>>52393323
No, it's not, you don't learn any useful programming concepts in python except the very core fundamentals which even a 6 year old could learn to do in C. Accept that you made a shitty choice, cut your losses and start learning C.

>>52393606
You not liking a language doesn't make it bad, nor does it mean that it won't teach you programming.

I don't consider forcing you to learn how to implement your own basic container types (because the language doesn't have any) to be a positive aspect.

If you *want* to learn how to implement data structures, it's entirely possible to do that in any language (I learned most of it in Basic, and I mean something not very far removed from the original Dartmouth dialect, not VB).

i agree that python shouldn't be a beginner's only language, but you wouldnt say that java is a useless language to start learning with if it has all of the shit in the standard libraries, no?

>>52394001
In roughly the same way that learning to drive is easier if you don't have to first build the car from a pile of iron ore.

Figuring out a path to a goal is easier the closer to the goal you are. You can't teach a beginner "this is how you add/subtract/multiply values, here's how to use an array, now use that knowledge to write a first-person shooter".

If you take a complete beginner and start with "this is how you manipulate a linked list", "this is how you manipulate a btree", etc, their response (either internally or vocally) is going to be "what's the point?".

It's more effective to demonstrate how to perform concrete tasks with higher-level building blocks, then move to the lower levels once there's some understanding of how programs work.

When I started, the first lesson revolved around READ and PRINT[1] so you could immediately make the program actually do something tangible. Once that's understood, you can start dealing with calculations, storing data in arrays, etc.

[1] PRINT *literally* printed stuff; this was on an ASR-33.

>>52394249
Writing C++ without OOP is among the best ways to write code if you care about performance (which is why you write C++ and not in some other more convenient language, right?).

If you want to be more efficient in some way do some metaprogramming. We don't have good performance oriented languages right now, that's why you don't feel right about things I think.

>>52394887
especially while(1) loops. Those things slow it to a crawl

>>52394944
speaking of, what's the deal with those?

There's always a break or return on condition, unless you actually want an infinite loop, so shouldn't they be considered bad practice?

Are there design philosophy differences in having void functions with pass-by-references as opposed to having many separate char/int/double functions that return one value?

>>52395033
Infinite loops aren't exactly rare

>>52395045
There's not much point in splitting up a function unless it can justifiably be said to be doing more than one action.

For example, if your function is more than a page long, then that function is obviously doing a lot more than its name describes and should be refactored.

The build files being in xml doesn't help.

Travis CI is a service for continious integration. Basically the simple thing you can do is for Travis CI to automatically test any new code commited to a repo and report any failures. You can configure it to do things like use different compilers or versions of software and to run tests to make sure things still work.

To deploy software generally means to run and configure the software on some computer. For example you deploy your web application to the production server. With tools like Travis CI you can automate the entire deployment so that once it completes successful testing it can deploy it.

I got sick of working on my music player, adding more and more features is just a lot of treading the same ground, I found a nice dictionary and made a password generator and a typing speed tester.

Now what? I'm not all that competent and I feel like I'm limited with C# because all my applications are UI driven.

Any ideas?

>>52396583
Learn C. Write some openGL code. Maybe a hardware-accelerated UI framework.

>>52396609
>Learn C

I'd like to get done learning C# really, I can barely string things together, I'm nowhere near ready to learn another language yet.

>>52396617
Learning C will help you understand C# much better. I promise.

>>52396638
I think the leap from barely understanding one language to trying to write a framework using hardware acceleration and a different language is far too great.

Even if I understood the language, I don't know how I'd even begin writing a framework, let alone one that interacts with complex concepts like hardware acceleration.

What's something I that would take less than a month to develop and be something I can put on my github and portfolio?

>>52396662

Guy who actually knows C# here
>>52396638
this guy's yanking your chain.

C# has almost nothing to do with C/C++
In fact its roots are as an improved Java tied to the .NET Framework.

The only real relation C# has to idiomatic C++, is that certain language constructs are the same. In other words, it has pointers, albeit you have to use them in unsafe{} scope.

C# in turn has almost no relation to idiomatic C.

>>52396748
To annoy you.

>>52396734
Do you know C? Learning C will help you understand any C-style language better. This includes Java and C# obviously (and even Javascript), because they inherit a lot of syntax and cruft from C.

Learning C peels away a lot of the abstractions you take for granted and forces you to figure out how they really work, which, again, makes you a better programmer in general and aids your understanding of other languages.

Learning C will help you understand why Strings are so shit in C#, for instance.

>>52396617
>I'm nowhere near ready to learn another language yet.
That's exactly why you need to learn another one. Only by having used multiple languages of different kinds makes it possible to understand the advantages and disadvantages of each one and thus getting more proficient in the general "programming" category.

>>52396734
Can you recommend a decent project that would give me a moderate challenge and get me to cover a lot of very useful topics?

>>52396736
I'd just like to interject. What you're referring to as a panorama is in actually a series of images put together in a slideshow, or as I've taken to calling it, std::vector<Picture>, or "Turntable".
There really is a panorama, and people are using it, but panoramas are in actuality a series of shots stitched together to produce a wide angle image.

>>52396781
Have you already tried LINQ?
If you haven't, then you probably want to start integrating your music player with a real database, and then begin creating search queries using LINQ.
You can also try dicking around by extending IEnumerable or other built-in .NET data structures with extension methods.
This is where the real power of C# comes in that separates it from the crowd.

If you want to brush up on your software engineering chops, I suggest you look up WPF and MVVM, also called MVCVM by those who don't want people to forget about the controller.

Admittedly I don't understand idiomatic C too well--I often get stuck because I hate learning about I/O in any language, and C has it the worst.

You're correct in that everything is much more manual in C, but the problem is that idiomatic C does not translate to idiomatic C++, because of OOP.

At best, I believe that what you will learn from C is how to appreciate managing resources (memory), and the usefulness of pointers and references.

Possibly also a healthy hate of I/O.

>AI Coding

Think from the perspective of the thing you're trying to give AI to.

I don't know a great deal about it generally, but I know that if you want to emulate a certain behaviour it's much easier to walk through that behaviour in your head and think of each logical step you'd need to take in order to achieve the desired outcome.

>>52396853
If you program some extension methods for the IEnumerable interface using lazy evaluation, then you will understand how LINQ works.

If query expressions are too confusing (they're designed to resemble SQL and relational database queries), you should try the regular notation, also called dot notation.
Dot notation is designed to resemble classical programming.
Treat it as if you're writing a pipe and filter application and that you're simply chaining functions together.

>>52396866
I want to take a shot at the Turing test.

>>52396869
As an example for an extension method, try implementing Python's Zip function in C#.
https://docs.python.org/2/library/functions.html#zip

For reference, C#'s IEnumerable Zip function is not similar to Python's Zip function.

I'm having a hard time motivating myself to do projects. This slump is horrible and I want it over. I want to do some lover level programming because for the pas year its been mostly web development. Any ideas of nice projects that will invigorate me? I like C but I guess C++ is fine as well.

>>52396853
>>52396819
Woops, for some reason I forgot to write the second half of my post.

I'm already using WPF, and I'm competent enough at databinding. From what I understand MVVM is a concept that describes the idea of having your UI reflect your current data and having the changes on the UI directly modify the data, without the middle man.

That's all I really took from my time on Google, because most of what I saw in actual code was a giant mess of almost indecipherable nonsense.

Sorry for the late response, I just took a fat ogre shit in my swamp.

Your understanding of MVVM is flawed.
MVVM is something called a design pattern (proven solution style to a known problem), and its primary duty is to separate the front-end logic from the back-end logic.
This is done using the View and the Model.
The View holds all the front-end logic--the XAML you've hopefully been writing by hand.
The Model holds all of the data and logic related to modifying and producing the data,

The controller still exists in MVVM, and is often called the "glue". It's the logic that the View binds to. It safely separates the View from the Model so that the View does not need to tailor itself to the model, and the model does not need to tailor itself to the front-end.

In design-patterns, this is called a bridge.

The ViewModel is also a part of that bridge, and what it does is translate between the View and the Model.
The controller being the glue is what allows the View and the ViewModel to communicate and update each other. This process is called binding, and simply refers to message sending between the front-end XAML and back-end C#.

>>52397169
Extension methods are a special kind of function in C#. They allow you to populate an existing namespace outside of your own source code.
In this case it would be IEnumerable.
So for example, if you wanted to run a function like

dynamic foo = new List<Integer>() {1, 2, 3 , 4, 5};
foo.Transpose();//rotates list 90 degrees clockwise

Transpose() is not a function available in IEnumerable's list of function prototypes.
So to add it, you would create an extension method.
In this case the extension method would be something like

public static class Extensions {
      public static IEnumerable<IEnumerable<T>> Transpose(this IEnumerable<T> data) {
        foreach(T item in data) {
            yield return item;
        }
    }
}

It does what it says on the tin. The key thing to note here is the parameter "this IEnumerable<T> data".
The "this" keyword denotes that it's a function that pulls data from its own object, and that "data" is used to refer to that object. Useful because you can't ordinarily access it outside of the namespace.
The "static" function specifier and "static" class specifier denote that the function should always be publically accessible, which makes sense for extension methods, and so it's a requirement.

>>52397272
actually that first block would be

List<Integer> foo = new List<Integer>() {1, 2, 3 , 4, 5};
List<List<Integer>>bar = foo.Transpose();//rotates list 90 degrees clockwise

note the difference--functions used in IEnumerable always return something, and IEnumerable goes hand-in-hand with LINQ.

I can also see the basic problem you're having.
It seems the main problem with the way you're learning C# is that you only know syntax.

You're pretty much code-monkey tier right now and don't understand OOP really at all.

Unfortunately I don't have anything for you regarding that. I can explain things to people who already have a strong foundation in imperative programming paradigms but I can't teach anyone the basics of anything.

>>52393163
This is total bullshit.

Having learned 8 programming languages including Python, I can safely say that at least 95% of the concepts are shared by all of them. The differences come down to syntax and individual language features. Almost all of programming simply involves being able to break down problems into smaller sub problems which can be solved one at a time. This skill doesn't depend on whatever language you're using.

Is there a dynamic way to create an object with N parameters in java?

I have this situation where i must create an object to supply the values for a query. The query is dynamic and the amount of parameters varies.
Let's say i have

 SELECT * FROM table WHERE field = ? AND field2 = ? AND field3 = ?

This is created in a way that field 2 and 3 might not exist, and so the object i create cannot have them at all, not even as null.
So,

queryObject = new Object[]{"field1", "field2", null};

doesn't work when i don't have the field 3 parameter, because null is still accepted as an input, and the query fails.

How would you guys go about it? My solution is bothering me to the bone.

    if(dataInicial != null && !dataInicial.toString().equals("") && dataFinal != null 
        && !dataFinal.toString().equals("") &&  almoxarifadoId != null && !almoxarifadoId.equals("") 
        && tipoMovimento != null && !tipoMovimento.equals(""))
        queryObject = new Object[]{new Integer(999009), dataInicial, dataFinal, almoxarifadoId, tipoMovimento};
    else if(dataInicial != null && !dataInicial.toString().equals("") && dataFinal != null 
        && !dataFinal.toString().equals("") &&  almoxarifadoId != null && !almoxarifadoId.equals("") 
        && (tipoMovimento == null || tipoMovimento.equals("")))
        queryObject = new Object[]{new Integer(999009), dataInicial, dataFinal, almoxarifadoId};
    else if(dataInicial != null && !dataInicial.toString().equals("") && dataFinal != null 
        && !dataFinal.toString().equals("") &&  (almoxarifadoId == null || almoxarifadoId.equals(""))
        && (tipoMovimento == null || tipoMovimento.equals("")))
        queryObject = new Object[]{new Integer(999009), dataInicial, dataFinal};

On and on for 9 else-if blocks.

>>52397594
Stuff like that is relatively easy to understand, if you change a method over to static you can no longer access non-static variables and shit, so you can grasp the function of something relatively quickly when it makes a difference that you can see immediately.

Trying to piece together what all the different syntax means from a code snippet online is quite a challenge when you have no frame of reference for what those words mean generally.

What does merge do in Git? Does it just add all the commits from your branch to the master?

>>52396926
OpenGL extensions are for very specific things and often get added to later versions of OpenGL
For 2D you don't need to concern yourself with them

put that shit into assertions and catch the assertion error

and before posting anything that disgusting ever again format it on separate lines for each condition

revolting

>>52398080
Merges can happen between any branches, and it applies the changes from one branch to another. Usually people merge stuff onto master, though.

Most commits have a single parent (the commit that came before it), but "merge commits" are special in that they have multiple parents.

Sometimes both branches make changes to the same spot in the same file, so git can't merge it automatically using its algorithms. In that case, it's called a "merge conflict" and you generally have to manually resolve it (but usually it's easy once you get the hang of it).

Hope this helps, anon.

Maybe compared to something like Coq or Idris, but it has a better type system than 90% of languages out there

The error happens when the query is being executed on postgres, i can't catch it because it's not an error per se.

Plenty of people use Unity for simple applications unrelated to gaming for it's cross-platform capabilities combined with easy GUI design.

I have a list of unsorted integers with repetitions. How can I make this into a list of integers with no repeat? I'm using C#. I know there are many ways to do this, but I want to know the fastest way because my program is computation intensive.

example:
13  13  5  13  5  3  2  1  2  8  1

output:
1  2  3  5  8  13

>>52398559
Put 'em in a set.

Do it with all the ways you know, measure execution time, post here

How to decompose a float:

let exponent x =
  let rec div accu x =
    if x >= 2. then
      div (succ accu) (x /. 2.)
    else
      accu, x in
  let rec mult accu x =
    if x < 1. then
      mult (succ accu) (2. *. x)
    else
      -accu, x in
  if x >= 2. then
    div 0 x
  else if x < 1. then
    mult 0 x
  else
    0, x
;;

let mantisse x =
  let rec loop accu x =
    if x = 0. then
      List.rev accu
    else
      let accu, x =
        if x >= 1. then
          1 :: accu, x -. 1.
        else
          0 :: accu, x in
      loop accu (2. *. x) in
  loop [] x
;;

let split x =
  let exp, x = exponent x in
  let mantisse = mantisse x in
  mantisse, exp
;;

>>52398559
For small list like that brute force should be fastest
Otherwise maybe HashSet

>>52398461
What experience in the field qualifies you to make these assertions?

I mean, I don't like Unity, but I can't deny that plenty of people use it for valid reasons. I know a bunch of script kiddies do too, but that's irrelevant to the former group.

Is it worth investing time learning ASP.NET MVC? Seems like the old WebForms blows it out of the water productivity wise.

>>52398774
For the CV, yes. For yourself, no, it's shit.

>>52398774
I got ass cancer last time I delved into MVC, but apparently it's pretty valued in the 'stry.

>>52398807
Shit. I've been seeing more and more people requiring it. I've given it a try, it just seems like I have to jump through a lot of hoops to get the same things done.

>>52398866
Don't forget. To be hire you need to have done things, not to be capable of doing things.

I'm already experienced in WebForms. It's what we use where I work and I have a few projects under my belt.

The problem as I see is that all that experience is going to be wasted. I could start working using MVC on small projects, but it would be hard getting other devs on board with the idea.

I basically had to force them to learn EntityFramework and Linq in general.

That has nothing to do with "muh design patterns". Read SICP.

>>52398715
You're going to have to go into more detail if you want help. You are probably going to need some way to backtrack, because it is possible to end up in a corner. Look at the following sequence

A B C
H I D
G F E

after I you won't be able to place J, so you will need to backtrack and try a different sequence.

Fix this before anything else

Jack and Jill have decided to separate and divide their property equally. Each of their N mansions has a value between 1,000,000 and 40,000,000 dollars. Jack will receive some of the mansions; Jill will receive some of the mansions; the remaining mansions will be sold, and the proceeds split equally.
Neither Jack nor Jill can tolerate the other receiving property with higher total value.
The sum of the values of the mansions Jack receives must be equal to the sum of the values of the mansions Jill receives. So long as the value that each receives is equal, Jack and Jill would like each to receive property of the highest possible value.Given the values of N mansions, compute the value of the mansions that must be sold so that the rest may be divided so as to satisfy Jack and Jill.
Is it possible to code something like this ? is there a specific algoritm for this kind of problem /dpt/ ?
