First for Null-terminated Byte Arrays

I looked at a bunch of assemblers like MASM and FASM and GASM and they include lots of macro facilities that resemble C, like syntactic sugar for loops and functions and stuff.

Does that mean C is a macroassembler?

First for Ada

Assembly languages usually have same kind of simple macro system as C.
You define macro token and it expands into something.

3D arrays
>>60334610
>>60334624

business idea: instead of creating arrays within an array for a 2 dimensional n * m matrix, instead have a single array of length n * m where first n blocks are in column m = 1, blocks 2n to 3n-1 are in column m = 2, etc

radical enough that it might work?

From last thread:

I've been programming on and off for a couple of years now, and it's only been in Lisp with a functional style. It's great and I love it, but I want to try a new language. I'm having a lot of trouble trying to decide between C++ and C# though. I want a language that's cross-platform. I want a language with high-level features. I want a language with a lot of ready-to-go libraries available and documented (Scheme-inspired minimalism is great but a huge pressure point when I work on larger projects and have to roll things entirely by hand). I don't want to spend time allocating memory if I don't have to.

I was going to go with C#, but it feels like there's a lot of turmoil going on with .NET/.NET Core/.NET Standard/Mono and all of these frameworks don't seem to inter-operate smoothly. I really don't want to deal with that. Then I was thinking of C++ but I know it as a very clunky language with a lot of manual memory management and I don't want to deal with it. However, it's been around for ages and so has a shit-ton of libraries for a lot of things and is very stable even when standards are updating. However, I've heard that "modern C++" or C++14 and 17 actually reduce the memory and pointer management you need to do by a lot and even have lambdas and so on. One person mentioned that they rarely had to manage memory at all and felt that contemporary C++ was like having a high-performing scripting language. That sounds hyperbolic, but I'm more open to trying it

What should I do, /dpt/?

>>60335030
I mostly used Scheme languages, where pretty much everything is functional by convention. However, I don't think there's going to be much of a difference besides syntax/style and libraries if you go from there to Common Lisp. They both heavily leverage return-by-default, values, higher-order procedures, etc. Just pick a project with a lot of stars on GitHub in a Scheme language and then translate it to Common Lisp if you want some practice.

My media database thing is coming along well. The media viewer zooming/panning is now nice and smooth and I got libvlc all figured out, so it can play all sorts of video/audio files, render subtitles etc. So now basically any media type aside from PSD/RAW images and other stuff like that can be viewed. I need to add a better way to categorize things on top of tags though, like AoT doesn't have v# in the filename so it can't be searched by volumes.

Do you know how large a pointer is, and how much overhead there is with tiny heap allocations? UTF-32 would be significantly more efficient, especially when you consider pointer dereferencing overhead like TLB misses.

I've crashed Matlab 3 times doing basically nothing. How do they get away with charging small fortunes for it?

Did you ever consider that string indexing isn't even that important of an operation? Most of the time you just iterate over ever character in the string.
I highly doubt your stupid memory hungry UTF32 is going to help much. You're making it so you can fit FAR less shit into the cache, which might even cost as much as just iterating over the fucking string.

>>60336041
This, also consider that a pointer is likely to be 64 bits.

What does /g/ thinks about "Think Python" book?

Should I use it?

>>60336094
I agree, but you have to admit that Rust not having O(1) character indexing in strings makes for a great meme

Does Rust have dependent types yet? If not then there's absolutely no point in using it.

>>60336094
array indexing in rust would let me write a trivial solution that seeks out the Nth UTF-8 character in a utf-8 string by returning a pointer to it's starting point.

>>60336147
>seeks out the Nth UTF-8 character in a utf-8 string
This is not a common requirement. Easy unicode and i18n is much more important for most applications.

>8 arrays
I really don't follow. And the problem with searching is keeping track of indices and false-candidates, e.g P(1,n), P(2,n), P(3,n) could be cyclic, but so can P(1,n), P(2, n), P(3,n + 4), so you need to save the path. Or a set can all be cyclic save for the last element with the first. Anyway, I figured it out, but it took over 10 hours of rewriting code and questioning my sanity, and also feeling like an incompetent imbecile.

>>60334661
UTF-8 is only ``good" in comparison to other encodings of Unicode (which despite having ``code" in the name, is NOT an encoding but rather a character set).

>>60334726
Even on a 32-bit system, that's going to nearly QUINTUPLE the space needed, when you add it to the space needed by the string itself. On 64-bit systems, that's going to amount to an average of nine bytes per character. You're better off just using UTF-32, as that gives constant-time access with less than half the space.

>>60335045
It probably means you forgot to specify the type of one of the arguments to one of your functions. Although I'm not sure why it's referring to a whole source file as a "function".

>>60335089
No, every non-static method had an implicit "this" parameter that refers to the object it is being called on. That's standard OOP technique, the only mainstream language I can think of where you need to explicitly define a "self" or "this" parameter for member functions is Python.

>>60336251

Is there a way to translate Matlab scripts to C/C++?

>>60336280
That's one of the reasons I was also looking into C++, C# doesn't seem to have anything here except something called

dynamic

, partial classes, and editor-based code generation. However, the truth is that I don't often use macros while programming lisp but when I do use them they are very convenient. I'm more interested in how much memory/pointer management I can avoid doing. It seems like C# is a much more high level language than C++, but I've heard this has been changing recently but I have no idea what that means from a relative and practical point of view.

>>60337205
Neither, they're both really bad first languages regardless of how you feel about them as "industry" languages. Go is opinionated in a way that's specifically intended to hinder programmer flexibility. C++ is a massive language with compilers supporting different standards that happens to have a C-like appearance despite not actually functioning like C at all when following best practices. Many tutorials are written for certain standards and unless you're familiar with the major differences in best practices it can be hard to tell whether the tutorial you're following is going to be wrong or outdated.

Learn a language that's more consistent and flexible instead, Python is a commonly recommended one and Racket Lisp is another good one. Both are easy to pick up and scale well with the person learning them as they expand past "hello world" style projects.

This code makes the gradient shown with a size of k*k.
It's very slow.
How do I do this faster?

k = 16384
    
id = np.zeros((k,k,3),dtype=np.uint16)

for y in range(0,k):
    for x in range (0,k):
        id[y][x][0] = x * (65536/k)
        id[x][y][1] = 65535 - x * (65536/k)

What are the odds that I watch that gif while I'm listening to some guy's discography, and shortly after decide to go check out the movie that the current song is from, and see this.

SPOILERS REEEEEEE

So just trying to figure out data binding in winforms.

public partial class Form1 : Form {
        List<string> list;
        BindingList<string> bindingList;
        public Form1() {
            InitializeComponent();
            string[] array = new string[] { "A", "B", "C" };
            list = new List<string>();
            bindingList = new BindingList<string>(list);
            listBox1.DataSource = bindingList;
            listBox1.SelectedIndex = -1;
        }

That displays a listbox with a, b, c in it. Having a button to remove the selected one from bindinglist will remove them from the listbox.

My problem is, lets say I have another class

class Parcel {
        private string trackingNumber;
        private int length;
        private int width;
        private int height;
        private double weight;
        private double volume;

        public Parcel(string trackingNumber, int length, int width, int height, double weight) {
            this.trackingNumber = trackingNumber;
            this.length = length;
            this.width = width;
            this.height = height;
            this.weight = weight;
        }

        public double getVolume() {
            return height * length * width;
        }

        public double getWeight() {
            return weight;
        }

        public string getTrackingNumber() {
            return trackingNumber;
        }

So lets say I create 4 parcel objects and add them to a List<Parcel> list then

BindingList<Parcel> bindinglist = new BindList<Parcel>(list);

How do I get the listbox to display getTrackingNumber() from each of the parcel objects

If I get singles, I will finish that programming book I was reading.
If I get dubs I will finish off that program I was writing.
If I get trips, shit post on /g/ more

That's what I did all day. It fucking sucks.

Trying to learn ASM. I compiled the following function:

int add (int x, int y) {
    return x + y;
}

with -static -fpic -O0 and it gave me the following code:

push   %rbp
mov    %rsp,%rbp
lea    -0x1040(%rsp),%rsp
                          
orq    $0x0,(%rsp)
lea    0x1020(%rsp),%rsp
                          
mov    %edi,-0x14(%rbp)
mov    %esi,-0x18(%rbp)
mov    %fs:0x28,%rax
                          
mov    %rax,-0x8(%rbp)
xor    %eax,%eax
mov    -0x14(%rbp),%edx
mov    -0x18(%rbp),%eax
add    %edx,%eax
mov    -0x8(%rbp),%rcx
xor    %fs:0x28,%rcx
                          
je     4a <add2+0x4a>
callq  4a <add2+0x4a>
leaveq 
retq

I think I figured what most of it does but I'm having a hard time understanding what the two 'lea' and the 'orq' are supposed to do. Can somebody explain that to me?
Also, is there a concise resource that explains what each instruction does? Intel's manuals are very large.

So I got this code that's supposed to make my scene scale with the window size (framebuffer width/height) by using a transformation matrix, but for some reason my transformation matrix is only scaling the textures on objects and not the objects themselves, so when the framebuffer becomes large enough the textures just fall off the edge of the geometry they are attached to.
What do?

    GLint transform_location;
    GLfloat ndc_scalex = pow(window->framebuffer_width, -1);
    GLfloat ndc_scaley = pow(window->framebuffer_height, -1);
    GLfloat ndc_translatex = ndc_scalex, ndc_translatey = ndc_scaley;

    while (!glfwWindowShouldClose(window->main_window))
    {
        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
        glUseProgram(shader_program);
        glBindVertexArray(vertices_vbo);
        glDrawArrays(GL_TRIANGLE_STRIP, 0, 4);
        glfwSwapBuffers(window->main_window);
        glfwPollEvents();

        glfwGetFramebufferSize(
                window->main_window,
                &window->framebuffer_width,
                &window->framebuffer_height);

        transform_location = glGetUniformLocation(shader_program, "transform");

        GLfloat transform[] = {
            1.0f, 0.0f, 0.0f, 0.0f,
            0.0f, 1.0f, 0.0f, 0.0f,
            0.0f, 0.0f, 1.0f, 0.0f,
            0.0f, 0.0f, 0.0f, 1.0f
        };

        transform[0] = ndc_scalex * window->framebuffer_width;
        transform[12] = -1.0f + ndc_translatex * window->framebuffer_width;
        transform[5] = ndc_scaley * window->framebuffer_height;
        transform[13] = -1.0f + ndc_translatey * window->framebuffer_height;

        glUniformMatrix4fv(transform_location, 1, GL_FALSE, transform);
    }

1. Disassemble with the -M intel switch, AT&T is eye cancer
2. orq is just bitwise or, q indicates it's working on a quadword (64-bit). lea is "Load Effective Address", chapter 9 of Assembly Language Step-by-Step has a great explanation of it
3. Look at volume 2 of the Intel dev manuals, the explanations there are pretty good. There's also a few reference guides online that pull directly from it.

Thanks for the tip, -M intel is indeed better.
I meant what are their purpose? I understand we're saving the stack pointer before doing the first lea and grabbing arguments after the second lea but I don't get what the two lea and the or are meant to do.
Thanks for the book recommendation.

>>60339902
It's a roundabout way to reserve 32 bytes on the stack, no idea why it does it though. Really there's all sorts of instructions there it doesn't really need, they might go away on a higher optimization level though

Nvm I just watched it and it wasn't really a spoiler

I want to make my code more pretty. Not really sure how.
For example :
I have a function which creates a kind of zipped container. Within this 50lines function, there are around 10 lines of creating the name, path and giving out some progress information.
Should I create a second function which handles this shit? Or just leave it in the createfile function?

>>60339738
Compile with -O3 so you don't get garbage. It will honestly help.

I would like to point out that openCV seems to assume there that the image plane is orthogonal to the xy-plane, which does not necessarily apply. In fact, it only applies if the camera is pointed exactly parallel to the ground, which IRL obviously doesn't happen that often, and it's the reason why I constructed all that fancy bullshit.
Also it's 3D, and I need to remember to account for the person NOT standing in line with the camera and its "lookat" point.

It's resource-intensive. It's a way more difficult operation than adding numbers.

>>60340937
C defines a pointer to character as a string.

I wanted to work today but can't. Goddammit.

>>60341036
>resource-intensive
Adding float and int requires conversion of the int to float, then addition of two numbers that you can't simply bitwise-XOR to add them.
Adding a char to a string is as simple as requesting the appropriate amount of memory, then copying both variables.

It's not simple in the slightest!
Converting int<->float is trivial, your processor does that in one instruction.

Are buffer overflows just a feature of C/C++ now? Every single program the world relies on has had security bugs related to buffer overflows in critical sections.

Oh come on, there are better editors than that.

As I claimed earlier, both python and C (and many C based) languages enable shitty programmers into the industry.

C has created generators upon generations of shitty programmers with their misinformed programming practices. C and python creates an illusion of "productivity" while _ignoring_ the underlying structures of their own programs.

"Weak-typed languages" and "type inference" are considered a norm now. Such a shame.

>>60341338
Yet the language pajeet is most known for is C# and Java and everyone knows the shittest programmers are Pajeets.

>>60341284
IntegerOverflowException isn't a workable solution in the context of C, so what are we supposed to do? truncating works 99% of the time and it has the least overhead. Do the overflow check yourself if you need it and you know what to do instead of truncating. Yes C is a DIY lang and it's intended as such.

You confuse it with C++, in C people usually realize underlying structures on their own.

Yes and no.

Let's say there have always been a lot of "bad programmers", because programming (on a higher level) is pretty difficult and takes a long time to master.

But Java doesn't give you so many options to shoot yourself in the foot. So we could say "C needs more experience than Java".

Something like Python.. well it was planned as replacement for bash, doing quickfixing and scripts. But people decided that often you don't need to get a deep understanding of "underlying structures" to make a "just werks app". I don't think this is bad thing, why does programmign has to be some arcane dark art? It's difficult enough when you use abstractions and libraries.

Of course it's important to get the details, theory and knowledge about datastructures and all those fancy algorithms when you get better, but for an entry level programmer / code monkey? Not really.

>>60334716
Just roll a dice and pick one, doesn't fucking matter. You can change in a week or six if you'd like. Probably you should learn C and memory management at some point anyway,just saying.

Yes. It is literally that, a good tool. Just because you personally are incapable of using it doesn't make it a bad one.

Learning Lisp-1 before Lisp-2 was a mistake.

>>60341446
Why? I haven't done lisp

>>60341004
It was me.
You can have multiple coordinate frames and just rotate and translate it as you want.
Say you have a point p in frame a, called p_a.
A matrix can be made which rotates the point to frame b, called a_R_b.

You can find the point in frame b as p_b = p_a * a_R_b.
And if there is a translation as well, you make the transformation matrix as [R|t]

This is the same as you are doing with the camera.
You need to project a point in 3d onto the 2d plane of the image and then multiply the transformation matrix to find the position in relation to your base world coordinate frames.

>>60341445
Wouldn't be the same thing if someone said:
"Yes. It is literally that, a good tool. Just because you personally are incapable of using notepad doesn't make it a bad one."

            System.out.print("Enter "+(i+1)+". element: ");
            T e = scanner.next();
            list .add(e);

[R|t] is only dependent on the camera position and orientation, correct?

>>60341179
You should go to C++ if you want manual transmission.
There we have a whole range of type casting you can do.
We also overload operators so we can control how they are handled.

>>60341468
What are YOU going to mean by misquoting?

>>60341203
Of course C wouldn't be something nonexistent.

>>60341500
Does C++ have type suffixes like 11i32 or 9.1f32?

>>60334716

Learn Java.

An experienced Java dev can be productive in C# within a few days and vice versa. Both languages are super similar. C# has cooler features than Java, it's basically "Java with benefits" (for example LINQ). But Java has way more jobs and is just better when it comes to cross-plattform.

And since you mentioned LISP:
You might take a look at Ruby. It's the smoothest "just werks" langauge ever adn you can do a lot of things you can do in LISP, way more than in Python. For example you can use continuations (like in Scheme) Ruby "fakes" macros pretty good with it'S meta programming abilities.

It is a rotation and translation of one frame to another.
Say your origin is (0,0,0)t and your camera is at (0,0,z)t, calculating everything as if the camera origin is (0,0,0) is fine, you just have to add z to the position.
In a matrix, this means having the number in a row, if that confuses you, see how matrix multiplication works.

It doesn't in the slightest, and it degrades preformance a bit. C++ has auto, it's not exactly the same, but it doesn't have downside of degrading performance.

>>60341626
What a pointless shitposting.

>>60341725
`auto` in C++ is nothing like `dynamic` in C#, the C# equivalent of `auto` is `var`.

>>60341741
Well, I clearly did say it's not the same.

>>60341746
You said 'it's not exactly the same', implying there are some similarities.

>>60341771
There are similarities.

>>60341779
No, there aren't.

>>60341806
Disagree with you on that one, buddy.

>>60341808
Then name similarities other than "you don't have to define a variable type" which is a non argument because the literal whole point of dynamic is that it has no variable type while auto just means the compiler/IDE knows which type.

Yeah, well, it might do different things, but if you instead of writing variable type would write dynamic, your program will still work, so you can do that with dynamic.

1. Game "programming" (as you put it) is one of the most difficult fields in programming with applications of things like higher math and artificial interlligence.

2. You usually don't programm games with Java or C#, but rather with with C or C++.

3. This may be a surprise for you, but "web "development"" is not just about writing shitty websites for the grocery story next door. It can be pretty complex. Please try to make a real-time dashboard with logging, messaging system and custom data analytics on a buisiness server of your choice with a website interface and THEN come back again and tell me about that funky "lele, web '''programmers'''" meme.

How do you think the computer makes all those move in a game? Of course there are a lot of "simpler" ways (like decision trees or A* algorithm), but if you want a "smart" oponent that adapts to your behaviour, you want some sort of intelligence higher than yours, anon.
