Currently converting some macros into user changeable settings, as well as just cleaning up the code and adding small features and changes that are too small to do on their own. I have an IRC channel dedicated to this project at #basictv on Freenode, but you can talk about whatever.

Playing with modifying, saving and loading a blocky gameworld in Rust following earlier success with OpenGL 3. Seems very robust if a bit verbose so far, at least I don't have to worry about accidentally streaming out ints when I intended to write u16 or something.

>>58591386
That means you're a newfag

OK, this might be a weird question

I learn c#, and i need to create objects in foreach loop

Since that is not possible, i have found workaround with dictionary, so i tried it somehow like this

Dictionary<int, User> dict = new Dictionary<int, User>();

and in my foreach loop i do something like this

                {
                    //do work
                    dict.Add(numerator, new User(car, price, link));
                    numerator++;
                }

Problem starts in another Method, in which i have to look through items in ObservableCollection MyClients and, if any link from dictionary is different than any item in the ObsCollection i insert it into ObsCollection

if (!MyClients.Any(x => x.Link == **HOW TO ITERATE THROUGH EVERY VALUE _Link_ FROM DICTIONARY** )
            {
                //do stuff
            }

When using smart pointers in C++, I only need to supply a deleter when the object is not dynamically constructed using "new"? Is this correct?

Doesn't the default deleter ("delete[]" if array, "delete" otherwise) pretty much handle this in most cases if your type can be destroyed cleanly by it?

I guess you might want something else if you're using your own allocator, pool mechanism or something, but it should destroy stuff created using "new" and then given to the smart pointer just fine.

>>58591595

>>58589719
In the end I do not know how to do this in a clean way, I'm already using more than one call to substr and I would gladly just use anything else at this point, but I'd have to rewrite the entire method

This is the easiest way I could think of without having to go for intermediate steps

sname*: (post) -> substr(post.file.name,_.match /\d{1,}(?=\,)/g or 0,_.match /\d{1,}(?=\])/g)

that is parameter when

parts[key] = parts[key].replace /%(T?URL|IMG|[sh]?MD5|board|name|%|semi|sname\[\d*(\,\d*)?\])/g, (_, parameter) ->
        type = Sauce.formatters[parameter] post, ext

goes

I don't think sname* would work, I don't know if coffeescript or javascript even let me use wildcards at all, let alone for string contents. Hell, I don't even know if I can even reference the formatter that is passed in there at all
this is all overly complicated for no reason

>>58591794
>am I overestimating the effort required to sort 4000+ songs seemingly instantly by their name/length/album etc.?

I'd guess C# is almost never used for embedded programming.

Visual Studio is probably the best tool for writing C# in. For C I'd recommend vim or emacs if you're already familiar with either of them.

>>58591792
>videogames should be a solitary pursuit
Not really. More players is more fun.
>>58591794
I would start with getting an environment set up with a ton of threads (one dedicated to audio, one for UI, etc). Just add a couple of locks together and you should be set.
>>58591800
Emacs
I've always known of C# to be a Windows programming language (although it has been ported over). I don't know of many prjects that actually use it.
C is the only language for embedded programming (except ASM). C#'s only embedded use case is WinCE, and that shouldn't count as embedded (64MB+ RAM)

>>58591749
Hmm, how would

[paragraph]
text="Test paragraph 1"

[paragraph]
text="Test paragraph 2"

map to a table?

something like

{
  {
    type = 'paragraph',
    text = 'Test paragraph 1'
  },
  {
    type = 'paragraph',
    text = 'Test paragraph 2'
  }
}

right?

I might do it anyways, seems like a fairly trivial task to 'compile' it to a Lua table and then load that, but idk.

Well, some Linux GUI media players do somehow slow down to a crawl or lock up when handling more than a few thousand files. But this probably has more to do with synchronous I/O and/or bad toolkit usage (I think one was creating a full layout of GTK+ widgets for every song available, whether it was visible or not).

How the fuck do i display multiple textures with opengl? I'm doing a completely 2D program so i dont' give a fuck about 3D. I'd use SDL but i'm drawing A LOT of lines (around 14k every frame) and so I needed to use VBOs to speed it up.

I've got that working and i've got ONE texture working but when i go to do the second texture (it's a GUI) it's just black. Do I need a second VAO? Do I need to generate another opengl program with a new shader? Right now i'm trying to reuse the texture shader (I have a separate shader for the lines) and reusing the VBO object, etc. I load the textures with SOIL and they seem to load find, it detects the dimensions, no errors. What sucks is none of the tutorials explain how to manage multiple VBOs/VAOs/Programs/Shaders, etc. They display one fucking texture and TUTORIAL OVER. God dammit it's driving me crazy. This is simple shit, JUST TEXTURES, nothing fancy.

>>58592068
I could propose dropping OpenGL, since you don't need 3D.

>>58592123
did you read the part about the lines? i need lots of those.

15k per frame is like 900k lines per second. SDL can't do that last time i tried. I was using RenderLine though, which is slow. I couldn't figure out any other way to do it as fast as opengl

>>58592068
Just bind the second texture object before drawing?
Does it have mipmaps? If it does not, did you disable mipmapping for it? It's on by default.

Reusing and reconfiguring the VAO doesn't have much of a perf penalty unless you really need to micro-optimize drawing 10k+ objects --- it's just another case where they took some existing global state (the vertex attrib binds) and turned it into a switchable object. Probably less confusing to just use them like that because it's fucking hard to avoid bizarre side effects like accidentally changing a "static" VAO's element array buffer while loading stuff.

>>58592170
Like i said i did BindTexture

It doesn't have mipmaps. It's a single layer PNG

I'm not reusing the VAO, I'm creating a second VAO, sorry if I misspoke. The rest of it i'm trying to reuse

>>58592289
i even tried other PNG files in case the first is bad

the other texture i'm using is a PNG and it displays fine, i can't figure it out, I'M ABOUT TO HULK SMASH MY MONITOR

>>58592289
If it's not broken mipmap configuration I can't really guess what might have gone wrong.

Run the program through apitrace to validate its GL usage?

>>58592068
Use a program like CodeXL to make sure the picture is actually loaded into the texture

It should just be a matter of binding the second texture and running drawarrays/drawelements again with the same VBO, VAO, etc.

>>58592389

yeah i'm using drawarrays

fuck! driving me crazy. ok i'll try codexl, i wasn't aware a program like that exists

>>58592331
>>58592389
>>58592170


In my render loop i really should only have to bindtexture and draw right? everything else goes in initialization? what about if vertices are changing? I just have to bindbuffer to vbo and fill the buffer right? anything i'm forgetting? i need to select the right vao depending on what i'm doing? fuck it's so god damn complicated

this is how I'm thinking doing that simple ui ml

>>58592489
If you're using multiple VAOs you should bind the VAO before drawing. Make sure whatever you do between drawing doesn't break its state. If you only have a single one just see that its attribs are bound to the right buffers and match your shader's vertex inputs.

Are you sure your code that tries to draw something using the second texture works properly? Just make the shader output bright red and if you don't see a bright red shape where the texture ought to be, your drawing setup is fucked.

If you _do_ get a bright red shape where the GUI should be, you're not setting up the texture properly.

Is this allowed in C?

Yes? You're telling it to pick up one float from the input and place it into "gal" but it still returns an int, which is the number of items successfully matched. Probably 1 or 0 in this case.
The guide you linked says the same thing.

It is in black and white because I didn't bother with converting from Y'UV to RGB (it shouldn't be hard, but i'm not working on video for a while).

I recently started a new job and have to maintain a bunch of old software.

How do I fight the urge to just rewrite everything because whoever worked on it before just copy pasted stack overflow answers together without know what the code even did and now nothing works properly and I'm supposed to fix it all.

Protip: Don't get a job doing programming unless you work on your own projects.

>>58592934

The scanf function returns an int, not a float. That int is the number of items successfully matched. If you want to scan a float with scanf, do it like this:

float gal;
scanf(%f", &gal);

With regards to safety in format string functions, just remember a few simple rules:

1. Never scanf with %s and no qualifiers for the length of the string.
2. Always use string literals with all format string functions. If you want to print a user-supplied string, use %s, or the puts/fputs functions. If you want to use a formatted input function with a user-supplied string... don't.
3. Don't use sprintf. Prefer snprintf.

In general, assume all user input strings can be malicious, and will try to overflow data, or read/write arbitrary data with %s or %n.

What do you think about my game?

Would you recommend focusing on .NET and C# development right now?

I got a job with great opportunities to learn this stuff, but I have to really delve into it.

>>58593195
Since you mentioned a separate VAO or buffer or something for the second draw, are the texture coordinates being passed properly? If the second texture contains black pixels, it could be just sampling that particular texel for every pixel because of bad texcoords.

If there is any doubt, make the shader improvise some kind of tex coords from view coords to see if any image data is coming through.

If you're not absolutely sure mipmapping is properly set up or disabled for that particular texture object (failure to do either will return black when sampling), try

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);

to disable mipmap scaling for the bound texture. Just put the call right after you bind the texture for drawing for a quick test.

What's the workflow for embedded development?

Suppose I'm developing on my x86-64 machine for some ARM processor. The fact that my code compiles and runs on my dev machine does not imply that it will compile and run on the target device. Conversely, I might not be able to compile the code on my dev machine because it lacks e.g some specific hardware that the application is supposed to interact with. So how the hell do people do embedded development? Do they use virtual machines and emulators?

How are you passing these? Note that if you're using two VAOs, you need to call glVertexAttribPointer and glEnableVertexAttribArray(was that the name?) for both VAOs, for all attributes you want to pass,

No Ruby. That's not how we do this. You're supposed to be confused, and then I post "doya doya doya doya".

>>58593394
since the ARM ecosystem is so diverse (10 SoC's with same architecture have 10 different MMU and initialization code) yes, they use emulators modified to their purpose (for example qemu has a versatile board and virt board that have completely different peripherals and ways of accessing em).

If you know C enough, you don't "have" to keep working on personal work. The Eudyptula project (Project Euler for Linux kernel development) might be a better fit here. Make sure you also learn how to use mailing lists, Git, patch, and similar tools. I tried the Eudyptula project, but it kept rejecting my code for some reason, so be warned.

Unless you want to do small fixes everywhere and just work on the staging parts, you should get some intense knowledge in some basic protocols (PCIe, USB, I2C, infinitband, etc) for whatever you are doing to help develop.

There's a special HTTP method for that which is HEAD. Use the --head or -I option.

Regarding Go, Rust, etc, do you actually use any of the newer features in your code (i.e. something you wouldn't find in python or C++)? Can you provide some examples?

The problem isn't that I don't understand lambda funcs etc... the problem is I can't really think of how they would be _useful_ in programming.

>>58593943
Step through each character of the string and see if it's 0-9:

if(str[i] < '0' || str[i] > '9') return false; //is not a int
}

return true; //is an int

    puts("Performing interest_rate_calculator.");

    puts("Enter loan: ");
    double loan;
    scanf("%lf", &loan);

    puts("Enter rate: ");
    double rate;
    scanf("%lf", &rate);

    puts("Enter days: ");
    int days;
    scanf("%d", &days);

    int interest = (int)(loan*rate*days/365);

    printf("%s%d\n", "Your interest is: ", interest);

    return 0;
}

>>58594006
The problem is I was using curl for a sanity check as my actual program requests it using HEAD and that's what's pulling the extra junk as well.

"HEAD /file.extension HTTP/1.1\r\nHost: s3.amazon.com\r\n If-None-Match: \"etag\"\r\n\r\n"

>>58594102
The compiler reads the file in order, so it has no point of reference to interest_rate_calculator when it reaches main. You should either put the definition of interest_rate_calculator above it, or put a declartion before main (don't write the function here, just 'int interest_rate_calculator(void);')

>>58594102
C is read from top to bottom.
When the compiler sees "interest_rate_calculator();", it hasn't seen that function yet, so it doesn't know about it yet.
You either need to prototype it, like

int interest_rate_calculator(void);

int main(void) {
    // ...
}

int interest_rate_calculator(void) {
    // ...
}

or re-order the functions

int interest_rate_calculator(void) {
    // ...
}

int main(void) {
    // ...
}

Most programs typically go with the reordering.

>>58594102
Declare the function before main so the compiler knows how it's called. The actual implementation can be anywhere, even in a different source file you link in later. This is how libraries work.

Implicit function declarations are old crap from early C that didn't really check if you were calling the function properly.

int interest_rate_calculator(void);
