Just made a thingie that extracts window handle and OpenGL context from SFML and injects QML engine on top of it, pretty satisfied with the results and it could easily work with SDL and GLFW as well.
The only downside is that there's no Qt event loop so you need to manually process events from your framework's event loop and propagate them to the QML proxy so that components can receive them.

How do I learn to write nice and readable code? If I write much code it gets unreadable

Hi guys

/* Question: What is proctecteed access specifier?

#include<iostream>

    public:
        Base() = default;
        Base(int l):prot_mem(l){}

}
int main(){
    Derived d1;
    d1.bar();//OK
    foo(d1);//OK

Why does the compiler complains about foo accessing protected int Base::prot_mem?

Incompetent assholes are trying to gain unfair advantages by riding the SJW/feminist bandwagon.

I need help with my C programming course.

The exercice is asking me to load up a set of data in a matrix of 30x12

Said matrix can be of one data type only but in each element I need to save two variables.

I'm at loss here, I know how to build up the matrix but how else do I make sure it saves two dinstinct variables in one element of a different data type?

I cannot use any record array.

>>60174018
Are the values integral?
If so just use bit packing.
Say the values are in range 0-65k, you can just use 32-bit integer and pack each variable in the lower & higher 16 bits.

bump from yesterday...
does anyone here know anything about x86?
specifically, x86 real mode?
or more specifically, how to disable write-protection on shadow-ram?

>>60174018
Array of structs.

If you can't use structs then use a 32 bit field, with the upper 16 bits for v1 and lower bits for v2.
That's properly autistic though.

>>60174036
Two variables an integer and a float(which is expressed in %).

>>60174049
But I need to save these data in the matrix remember.

Something along the lines of.

void set(uint32_t *val, uint16_t high, uint16_t low)
{
    *val = ((uint32_t)high << 16) | uint16_t low;
}

void get(uint32_t val, uint16_t *high, *uint16_t low)
{
    *high = val >> 16;
    *low = val & 0xFFFF;
}

>>60174113
I forgot to link the post: >>60174018

>>60174103
You can have an array (or matrix) of structs, anon.

A struct is a datatype btw, either you're not telling us something or your exercise is trying to be smart but is poorly worded and you can take advantage of it.

look up grub4dos.

I'm working on a minimalist versatile 2D game framework with C89 and SDL, it will pretty much be a bare bones data-oriented implementation of the ECS paradigm, but with an OOP-like interface, plus some really basic and essential component types like things that can have an animated sprite and a position on the screen and perform a behavior on a schedule, worlds that can be made out of tiles that can have various flags and sometimes be animated, a togglable system for checking collisions, etc. I'll then extend it with RPG elements and create one of those sentimental RPGs that people play for the story and aesthetic (e.g. Off, Lisa, Undertale, Yume Nikki, Mother 3, etc). Except I'll majorly shit it up. Then it'll be like a joke.

That's just sloppy. Anyway, thats an extension to grub. It's not a ""real"" full-blown operating system.

So I'm designing an Entity Component System for a small project in MonoGame and I'm wondering where does the implementation of specific interactions go? Say for instance I have a missle entity with an EffectComponent that makes the blow up effect. If the EffectComponent has a Draw method do I check some sort of EffectType or how do I go about differentiating different component types that are under the same component? Do I implement a MissleEffectComponent as a sub class of the EffectComponent and have it handled there instead?

>>60173814
Other than the algorithm being totally dumb, inefficient and ungeneralizing, you don't want to do this:

int result[4];
printf("%d", result);

that would just print the address of the array and not the array itself (hint: you need a loop for that too).

Also, why not printing the perfect numbers on the fly? You wouldn't even need an array then.

No idea what that is. Is it some kind of IRC server?

>>60175424
It was a long shot, never mind.

>>60175296
You could have the type of effect to produce be an element of the EffectComponent's state, in the same way, for example, that your core component probably has state like where its entities are on the screen.

To create an adjacency matrix graph in Java could I use a two dimensional (nxn) array to store the arraylists that store the edge & vertex objects?

Also how would the method look within an edge class that gets each of the endpoints within graph?

Any help is appreciated?

if anyone is interested

>>60175589
In an adjacency matrix, you don't need arraylists at all. You could have a two dimensional array of size NxN, and each cell would store any data you want to store under the edge between those two vertices, or null if there is no such edge. Then you could have an additional one dimensional array of size N that stores any data you want to store under the vertices themselves.

To find the endpoints of an edge within the graph, just look at the two indices into the two dimensional array you used to get to the edge, and there's your endpoints. In fact, under an adjacency matrix representation, it's generally assumed you use the endpoints to look up edge data, not the other way around.

>>60175589
Why? I don't understand what you are trying to do here senpai

  int[] weights;

  weights = new int[n * n];

  addEdge(i, j, w)
  {
    weights[i * n + j] = w;
  }

next problem, the dos memory chain somehow corrupts immediately after my program terminates. it's fine before the final return instruction, then suddenly the last block's Z is set to M for some reason and it ends up including rom code in the memory chain.
ugh why does this shit have to be so fucking complicated.

Newb here, why does python behave like this:

>>> 0.1+0.2
0.30000000000000004

I understand that small values are added and such. But why 0.1 + 0.2 gives retarded results, and other sums give normal results?

0.1 is a repeating sum in binary. like, how 1/3 in decimal is 0.333333333333333.

.1 in decimal is .000110011001100110011, etc. This stuff is binary, with only a certain amount of floating point precision.

Vices aren't inherently wrong, they're just conducive to wrongs. For example, a gluttonous, greedy slob can still be a good person, it's just harder for him than it would be if he gave up gluttony, greed, and sloth.

Trying to create an algorithm which will convert any undecidable problem into a decidable one.

this is a test post, ignore it

Currently trying to get my instruction fetcher for my processor working...

Instructions are variable length from 1-4 words in length. After all words are read it raises a 'done' signal and a finished instruction tuple is made available (PC, Instruction, Instruction_size, AccessOOB) for the decoder, which transforms the tuple into a much larger tuple of control signals. Every stage of the processor gets one of these 'signal wavefronts' before it goes on the next stage.

If the decoder decodes a branch instruction, the fetcher's currently executing fetch is invalid and it must pause execution.

Currently having issues with it working in the fully pipelined manner I expect (request for instruction word at the next address is fetched as soon as the previous value is made available). It's waiting until the next cycle to send the next request and set the 'done' flag. It's starting to piss me off, Verilog is a nightmare. I know exactly what I want, but the language is so unintuitive and baroque I'm having difficulty realizing the hardware I envision.

Facebook uses OCaml too https://ocaml.org/learn/companies.html

Facebook's spam detection service is powered by their library called Haxl (written in Haskell). Likely there was an existing regex library they built off of which was already verified by Haskell proj as a core library or something. If you do CMU's intro to Func Programming course and read Robert Harper's ML book, one of the first things they have you do is debug a regex library. Functional languages make it dead simple to build highly advanced filters and shit likely why FB uses it.

Haskell is also extensively used in Oil/Gas industry, and genome sequencing type work because of said filters applied to gigantic datasets. It's also used to make DSLs in those industries so they can hire people who don't know Haskell.

Using a vector of vectors isn't much better, because then I end up with initialization code like

I have no idea with respects to that, I find web stuff very boring. You can make a web server that does... uhh...

The whole point of networking is to communicate, whether it be people or other computers, so to me it seems like the whole philosophy and motivation of networking is to serve other people. If you are doing this for yourself you are probably going to have a hard time picking a useful project.

Personally, I'd like a nice free music streaming service I can put on my server. Something that has a well integrated command and control and streaming service. What exists currently usually just has clients as remote sinks and it literally streams the audio instead of the files which is just fucking retarded (local play is more reliable), and gives the user very limited or un-tightly-coupled control. A nicer way to do it is to have an audio player that play partially received files, buffer them, cache them locally to some preset limit (say 250MB). The client should allows the user to setup playlists and should prefetch the audio files, have the user be able to browse a library etc.

Naturally happens when you start getting into security.

First you wonder why everything is literally backdoored to fuck with weak standards, piles of bugs you find almost instantly and even weaker excuses for keeping everything weak. Then you discover it can only be that way by design and everybody thinks your hat is aluminum.

It's like reading DJ Bernstein's posts on the IETF crypto research working group mailing list. He consistently accuses people of trying to cram in sabotaged standards and they (often being direct NSA employees sitting on the groups) try and accuse him of being a tinfoiler but he's right, the shitty standards are by design http://bada55.cr.yp.to/

I have a coworker who, despite being very smart, and even very knowledgeable about software, writes the most horrible code imaginable. Entire programs are stuffed into single functions, artificially stretched thanks to relentless repetition; variable and class names so uninformative as to make grown men weep; basic language features ignored, when they could make everything shorter and more readable; and OOP abuse so sick and twisted that it may be considered a war crime. Of course, being a very smart person who has been programming since before I was born makes him fairly impervious to criticism, so even a simple 'Do you see how much better this function is when written this way?' is hopeless. How can I make him see the light, realize the truth, and be able to tell good code from bad?

And yet you want to copy the entire database to memory.

Either you have everything in a flat file and read it when the program starts, or you query a database. The database might actually be faster here.

You just have to understand that querying the database is the most performant option here.

The problem I have is, that the user, upon running a query, is supposed to select some items and then print them on paper.
I already have the database load into a datagridview upon program start, so the user can select all elements to print.
Based on the selection, elements are drawn so they can be printed. Is there a better solution?

I'm currently reading both K&R and LCTHW, but I don't feel like either are helping me 'think' the way that I need to with C.

How the fuck do I start thinking object oriented? I just type all my code in Main, regardless if I need to retype it later.
My colleague writes in objects that he uses in his own library. Despite that, I very rarely see him use it.
What's the appeal? How do I learn it?

>>60178998
Uhhhhh, I'm not that advanced. No clue whats happening there.

>>60179489
I'm not sure what you mean by that but you made me realize that I meant dynamic languages, interpretation vs compilation isn't my issue, I think it's the manual memory management and the fact that strings are treated like arrays and processed by each character.

>How the fuck do I start thinking object oriented?
If your brain isn't severely damaged already it's nearly impossible.

>>60179564
Right.

std::vector

is the same thing as vector if you have

using namespace std;

at the start of the code file.

So

std::vector<std::string>

is the same thing as

vector<string>

.

The & in

vector<string> &var

makes it so that the entire vector doesn't get copied when the function is called. It works fine without it.

for (auto name : names)

loops over all elements in names where name is the element that we're looping over at the moment.

name.substring(name.size() - 2, 2)

copies two characters beginning two characters from the end of the string, i.e. the last two characters. They are then compared to

"ed"

. If they are the same, count is incremented.

Most of the stuff in my version is just there to either make it a bit faster (&,

std::vector

), or just things that I prefer (

std::vector

instead of vector (btw prefer this in any serious project)).

>>60179663
The whole database is literally one table with one column, it's just that it has a lot of rows, that's why. And it won't grow, apart from rows.
I thought a database would be easier to manage than a txt file.

What database functionality are you even using if you only have one column.

I think a database might have been the wrong choice here, especially if you never add anything to it.

A "dynamically" typed language does not and cannot possibly exist.
>can you recommend any books that could help?
My only recommendation would be something which you said didn't help you. Just try writing a lot of programs, even simple ones. That's really the only way you're going to learn.

>>60179892
>A "dynamically" typed language does not and cannot possibly exist.
What the fuck are you on about.

Dynamic typing is a thing.

>>60179833
The posibility to run queries on it. There might be a second row coming, the program is still in development.
The thing is, I want to be able to easily add, remove or edit the data in the rows. Also to read in .csv files to add several rows at once.

>>60179905
>Dynamic typing is a thing.
How can something which is by definition impossible be "a thing"? It's a self-contradiction.

>>60179798

If you like Lisp, than it's obivous that you'd prefer Clojure.

I've heard that Clojure isn't a Lisp. I don't know why though.

Type-correctness can be checked at runtime, but that doesn't mean that the typing rules themselves are somehow dynamic.

How autistic is ASP.NET? Do I have to make the front end using the wysiwyg / other autismal microsoft tools? I have some C# backend code for a server application, and I'd like to make a website for it too. Trying to figure out whether I should use ASP.NET (since I have a lot of the backend code in C# already, this should be the best option assuming ASP.NET isn't TOO bad) or if it's easier to just re-implement a lot of it in node or something.

>The & in

If you're not using an ancient compiler, the vector will most likely not be copied, but moved to the function (look up move semantics). Passing a reference is perfectly fine (and probably cheaper than moving anyway), but I thought I'd mention that copying is not as much of a hazard as it used to be pre-C++11.

>>60179949
What about using an ORM like entity framework.
Your database will be held in a cached object at fiest run, so as long as your database object (dbContext) is running, your queries will be checked if said query result already exists locally.

I don't know, never used it. In fact this is my first actual project, that I am not doing just for fun. It's supposed to be a barcode printing program in which the user can select data from the database and then it is converted into barcodes, which are then printed to paper.
Care to explain more about the framework, or if there is a simpler way I can write my program?

>>60180216
I'd prefer to use no engine, I want it as vanilla as possible. Do I have to use anything ASP-specific on the frontend to make it communicate nicely with the backend, or is it all just standard HTTP commands?

>>60180232
Oh shit, didn't even consider hosting really. I'll have to double check because some of the backend might be using newer C# features that aren't in core, but that's a good point.

The biggest selling point of Lisp is that all code is just parenthesised lists,

(a b (c d e) f (g h i))

is not only valid syntax, but the only syntax.

Clojure breaks this promise by having

[a b c d]

be valid syntax.

Also a lot of the traditional Lisp functions are either missing or renamed.

So why are you not writing something impressive emojicode yet?

I was thinking about implementing a binary tree sort but the syntax is just so confusing

>>60180329
Not sure you'd have the time to learn the framework or if you'd be willing to use it. It has helped me before in both desktop and web applications and it's secure by default.

But the usage would be straightforward, you'd need to create a dbContext class, a model class which would have the same property names as the columns in your database, then install the provider for your database should be something like "entity framework sqlite" then generate the connection string.

Then finally you'd get the data using linq or raw sql queries for example:

gridView.DataSource = db.someTable.ToList();
//Or
gridView.DataSource = (from x in db.someTable.First(x => x.someColumn == someValue)).ToList();
gridView.DataBind();

or

var query = from x in db.Table
            where x.Column1 == "Value"
            select new TableModel { Column1 = x.Column1, Column2 = x.Column2 };

gridView.DataSource = query.ToList();

or

gridView.DataSource = db.Table.SqlQuery("SELECT * FROM Table").ToList(); 

Where db is a new context of the database set outside the scope of the list functions so it's always present to check for cache.

Just watched Patton and made some rice.

Here are the results of testing

>First clock is a reset state (rst is high)
>next clock initializes the memory read (ready is high)
>next clock data from the memory becomes available (valid is high)
>next cycle (!!!) done goes high and Instruction, PC, etc. are set
>this repeats 4 times
Though you can't see it AccessOOB goes high on the next 'done' because addr > MEMORY_SIZE (16 for testing).

I can't really see why there is the wait; hell when the next clock starts, data_valid is no longer high. If I can get it to work like that, then I can have fully pipelined fetching/decoding. There will later be an executive in charge of setting the invalidate flag to invalidate prefetched ops in the case of a branch.

Kind of as it is completely interoperable with Java but it's so much more. More importantly, it'll be compiling to LLVM soon which means you get native support.
