I made a python script to print images in Minecraft raspberry pi edition

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) ).
>>52392122
It's good to learn with because it's pure, there's no bloat.

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 scriptobjTest = {
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 objectfunction 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 beingfunction 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

>>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.

>>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.

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).
Who thought this was a good idea?

>>52394001
because there's more to programming than knowing how to define a struct? at an intermediate stage you have to know how to combine different pieces together at the least
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.

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

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.

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.

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

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.

>>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.

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.

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.

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#.

If you don't know if it's lighter or heavier it doesn't work, though, since if it's heavier and you weigh 3 and 3 of the lighter side they would be equal.

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 likedynamic 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 likepublic 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 beList<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 haveSELECT * 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.
