Like say that you have a quote character and you want to go backwards in a loop to count the backwards slashes prior to it to see whether it holds semantic meaning... impossible, you have to keep state.

Man I'm so mad. I spent a whole bunch of time creating a GUI in Nuklear + X11, but now I cant because there is a bug with how images are clipped in scrollable content. So now I'm learning FLTK and it's such a downgrade for ease of use...

>>103188268
>The way their everything-is-a-string thing works is diametrally opposed to the idea of references
Yes. It's a different value model entirely, where values are immutable and don't have individual identity. This lets the implementation share values a lot more; they're actually references, but with copy-on-write semantics so other uses can't observe the changes you make.
>references are what is needed to have real nested data structures.
No. You just seem to think you need to have ways to reach into a value deep inside a structure and modify it. I've always found that to be a source of subtle bugs.
For the cases you need something that complex, you've got variables and you've got objects. Those are named entities, and mutable.
>>103188278
No. It just doesn't and that's not about to change (because fuck knows how much user code would be broken by that). Most of the time you don't need lexical scoping as you have the ability to run code in parent scopes (and only Perl has Perl's retarded rules for non-my variables). You also don't typically need it for callbacks as you've got coroutines instead, and they're nicer than a nested stack of inherited-scope callbacks (or promises) as you can use genuine control flow for the state machine model.
There's probably cases I've not covered. Don't care right now.

Yes you can have immutable values and data structures but fuck that.
>For the cases you need something that complex, you've got variables and you've got objects. Those are named entities, and mutable.
That doesn't solve the problem of having mutable nested data structures. For example a struct containing a stack and a hash table, among other things.
>Most of the time you don't need lexical scoping as you have the ability to run code in parent scopes
That would be a good response for the inability to pass things by references, but for lexical scoping?
But yes functions have their own scopes of course, I'm not sure what I was getting at it's not fresh in my head. I do remember that there was problem concerning $name(index) and nested data structures.
>Perl's retarded rules for non-my variables
non-my variables are global variable. maybe you're thinking of the keyword local that doesn't change the fact that the variable "local"ized is global. global variables have their use but in most cases it's a bad idea to use them anyway, as you should know already.

Because compilers are retarded and you simply shouldn't trust them for performance critical stuff.
>>103184583
I don't understand what you mean by "keep state" or why this is hard at all. You can literally just AND the most sig bits of utf8 bytes to check what kind of byte you're in. You can count backwards slashes easily, you're just over-complicating things in your own mind.

>>103190030
This. Work on things that are actually useful.

>>103190394
i thought that the top bits signaled only when the encoding length would stop though?
Like, the second byte could be 110..... and be a two byte encoding or it could be 111..... or 000..... or whatever and keep going, thus making it impossible to move backwards, i might be wrong, i havent tested shit yet though utf8 is supposed to support 1 million+ characters off of that 4.3 million 4 bytes offer so removing 1+3+4+5 bits from the equation completely instead of only one of each's states seems strange

This is why normalfags mock people who are unemployed, they don't care what you do or what you can do or what you like doing, all they care is social ststus, the more money you earn, the better you are, that's why rich successful people who never worked a day in their life are highly regarded, whereas a humble NEET who spends less per year than the faggot wagie berating him per year is kicked down further on the spot, nothing else matters.

Are there idiot proof spring security guides that help you secure certain endpoints behind user auth and authorization? The more I look into the matter the more confused I get.

>>103194021

The idea presented by the paper "Trees that Grow" seemed like a great way develop a language from an initial syntax tree. I'm trying it out right now.

You can do this with normal labels in C as well, they're scoped to the function they're in, e.g. break func::label will set a breakpoint on the label label in func
Useful especially with gdb python scripting

You don't put those inside other arrays, and there's never been a supported way of doing it. (It actually was possible to do so at one time, but that was a bug and the only syntax for doing it was gross.) "Arrays" are defined to be associative maps from string keys to simple variables.
Most of the time, using some sort of structured value as the key works well enough. When you want something more nested, you've got dictionaries (which are insertion-ordered maps) that were new in 8.4 (which is now two decades old so "new" lol) where you can use any value at all as a key and stack them up inside each other as much as you like. (The test suite takes that to stupid levels of nesting; you don't need to.) The only real restriction is that you can't put a value inside itself, either directly or indirectly; if you try, you end up putting a copy inside instead.

The main option for doing a GUI in C right now is GTK, from the people who reject features for not having a use case they can comprehend.
Tcl/Tk 9.0 should be buildable into a single DLL/shared library without external support files. Bind your operations as commands and your globals as linked variables and you can use a very thin layer of Tcl code to hook up your application code to Tk. Direct binding's possible, but major annoying and not worth it; much easier to have a little extra binding layer.

I feel like I should be avoiding switch statements but I can't explain why...I just feel like I shouldn't.

Little by little, writing my own 6502 Assembler in Standard ML (will rewrite it in C++ for my 6502 simulator). Got the first pass down, updating the symbol table and getting the right bytes for them. Since a lot of instructions have they addressing mode, I'm using a deque for addressing modes on first pass so that on second pass I don't need to waste time finding out what are the addressing modes again.
I have been putting this project away for a long time so I'm happy I'm finally doing and almost finishing it.

there is no secret, you just have to chose something to build and build it. Then at some point while you're building it you realise you made the most retarded choice in the world when designing your code and either restart (unlikely) or just abandon ship and maybe revisit in a few years. If you want to go faster read how others did it, you learn a lot that way but NO TUTORIALS. Just think about how you'd do it and if you don't want to rollback 5h of coding check online see of the thing you're doing is done.
Each time you'll find that the LOC before you hit the wall get larger and larger and don't hit the walls as hard, you refactor more quickly (tests help a lot for this, particularly for dynamically typed langs).
Btw the walls I'm talking about are things like too much coupling, dogshit interfaces, retarded datastructures, overabstraction, etc...

Because they are not the same. I only care about the state of the CPU register and some memory "connected" to after running a program for 6502 ASM study. Thing cycles, etc are not important. Since I'm not trying to emulate the CPU, it's a simulator for analysis and study.

like 99% of people including those who have been formally taught the language struggle with the concepts behind C++ dependency resolution and build systems
it's probably the number one question people ask
for some reason explaining you need to add flags for the include directory, library directories, and individual library file is never enough
i'm not typing it out again, pic related is the quick rundown

build systems help manage that, everyone uses cmake even though it's shit
in cmake you add library directories (same idea as explained in the image) with target_link_directories, include directories with target_include_directories (same idea as explained in the image) and link to libraries with target_link_dependencies
sometimes a library might include a cmake installer which lets you use find_package to load a fake library that sets the other two automatically

Operator overloading for vector/matrix types is too convenient to give up IMO, even if you use nothing else from C++

>>103195716
Your matrix multiplication isn't good, as mentioned. But it's ok as a naive start because you have to start somewhere.
The big picture is that you want to start by breaking your gemm operation up into conformal blocks (look this up).
Once you've got that sorted, you want to optimise these blocks to minimise moving data between the registers and main memory. So you want to pick a size of these blocks which fits in the registers. There are some subtleties here, so it'll require some reading.
The goal should be to recast C += AB into a sequence of rank-1 updates to C. This is good because rank-1 updates can be done as a series of axpy operations. You can then optimise these axpy operations because all they are is going to be FMA operations.
So the trick to really high speed is to optimise these FMAs because you're going to be doing a lot of them. This is the idea of something called a microkernel. Normally you'll even write this in assembly.

>>103195716
>>103201836
https://planetmath.org/conformalpartitioning

>>103201836
Another point worth mentioning: Notice that whether you're storing matrices in row or column-major order (let's say wlog you're storing them in column-major order), when you do C += AB naively like this, you can access A by e.g. columns, but then you're having to access B by rows. This is something else to pay attention to. How would you solve that issue?
(Hint: there's a reason BLAS functions have all those arguments!)

Alright, let's say I have this in model/repository/whatever layer.

def get_post(id, transaction):
    return transaction.query("select content from post where id = ${id}")

def update_post(id, content, transaction):
    return transaction.query("update post set content=${content} where id = ${id}")

Then in my service layer, I want the ability to make a post all lowercase.

def make_post_lowercase(id):
    sql.transaction(def (trans):
        content = get_post(id, trans)
        content = content.lower()
        update_post(id, trans)
    )

But there's a problem- my DB's default isolation level is READ COMMITTED, and I used SELECT not SELECT FOR UPDATE, so there could be a anomaly here.
I could update get_post to use FOR UPDATE, but I also want to use that function without locking for situations where I'm not updating anything.

Do I add a separate get_post_for_update? Do I add an extra parameter to the function and include FOR UPDATE if it's true?
Do I add an update_post_content function which accepts a lambda, does a SELECT FOR UPDATE, calls the lambda with the current content, uses the return value to do an update?

You can write

and it'll be correctly handled (param replaced with a placeholder and sent separately). It's not just string interpolation, although it does feel a bit uncomfortable at first and could lead to errors when switching back to something that doesn't support this.

I am trying to figure out if I should be using singletons in python.

This says they are bad:
https://python-patterns.guide/python/module-globals/

I think the argument falls apart if you are creating something that requires some logic. I am creating a class that will update the db if a value changes. Otherwise it will load once and keep everything in memory. I know python doesn't really have encapsulation. That doesn't mean I want all my CRUD functions loose.

>>103206564
Safety rails. Async requires everything to be to Async. Variables are isolated to prevent deadlock. Nothing is wrong with what you put. It assumes that you will do something stupid.

True singletons? Rarely, and only for things that it's a really nasty programming bug to make several of.
Global constants of various sorts? No problem at all.
Global mutable values (by design)? Be careful, as you can easily get in a mess. Not saying never, but they're a code smell.

if only we had a standard instead of every fucking PLC programmer thinking they are the smart one. I'll curb my rant by saying that safety system buttons should be considered "1" when not pressed and you should be reacting when you don't receive the signal.

Thanks. That fits along what I have been thinking.

I am loading the entire lookup for a piece of information for efficiency. It is already stinky. I am justifying to myself by saying that it will only be modified during setup changes and not during normal operation. That is mostly true, but not completely.

am I supposed to be writing my projects as a collection of libraries, or is that just some dumb corporate thing?

obviously a list of tourist spots nearby. maybe good food places. a "language" section that helps communicate would also be useful (where is the bathroom, directions to such and such place, etc.). educational content about your country would also be interesting. finally, I challenge you to webscrape all cruises from all popular providers so tourists can choose which cruise is theirs and receive reminders about the cruise schedule.

I finally remembered it well enough to make an implementation that works.
Basically, you take data from the rdrand instruction, copy it to rax, do some massaging to it so it's not too small or too big, put the unmolested random number into rdx and then mul. Your new, semi-random number is in rax. All you need to do from here is exchange rax with rdx to regenerate again.
It's not a good regeneration technique. You shouldn't regenerate too much and you should never use it for anything meant to be cryptographically sound or approaching true random, but it is many times faster than basic rdrand and for quick and dirty assembly applications, specifically those where simplicity is king, it's not a terrible option and does the job quite well.

>this is what the registry retard means by "random number regeneration"
OK, so now we can all agree that you are schizophrenic about optimization because it is the only thing you *can* comprehend.

>>103212362
I'm not registry retard.
Also, it's not my fault you only speak your hyper-domain-specific dialect of asbergers instead of English.

Cope, a basketball coach yelling "TURN" has a very different meaning than a railway supervisor doing so has, you might not be a schizo but missing one symptom of mental retardation doesn't excuse you from a positive diagnosis.

>>103212333
Just use an MCG? Rdrand is slow, meant for seeding, not as a quick PRNG

>>103212656
PRNGs have evolved a lot in recent years, now we use xorshift-mul hashes like https://github.com/skeeto/hash-prospector

        char byte_one = ptr[0];
        if (byte_one & 128 == 0){ return 1;}

>optimized away because char is signed
I HATE THE COMMITTEE, CHAR IS USELESS FOR FUCKING CHARACTER PARSING

>>103212900
The whole 'plain char' thing is kind of dumb, but you're still a retard.

>>103212900
what are you even trying to do here

>>103212968
checking the length of a utf8 character

static int utf8_charlen(uint8_t* ptr){
        uint8_t byte_one = ptr[0];
        if (byte_one & 128 == 0){ return 1;}
        else if (byte_one>>5 == 6){ return 2;}
        else if (byte_one>>4 == 14){ return 3;}
        /* else if (byte_one>>3 ==30) We don't bother to check if a stream is wrong. */
        return 4;
}

>>103212900
>>103212926
128 can't be a signed char so I guess that's the problem

>>103213036
here's mine

int utf8_char_size(const uint8_t *c)
{
    const uint8_t    m0x    = 0x80, c0x    = 0x00,
                  m10x    = 0xC0, c10x    = 0x80,

                  m1110x    = 0xF0, c1110x    = 0xE0,
                  m11110x    = 0xF8, c11110x    = 0xF0;

    if ((c[0] & m0x) == c0x)
        return 1;

    if ((c[0] & m110x) == c110x)
    if ((c[1] & m10x) == c10x)
        return 2;

    if ((c[0] & m1110x) == c1110x)
    if ((c[1] & m10x) == c10x)
    if ((c[2] & m10x) == c10x)
        return 3;

    if ((c[2] & m10x) == c10x)
    if ((c[3] & m10x) == c10x)
        return 4;

    if ((c[0] & m10x) == c10x)    // not a first UTF-8 byte
        return 0;

    return -1;            // if c[0] is a first byte but the other bytes don't match

Theres this hydrus clone (not a fork, just a similar, and imho, better, image database program)
called FEMBOY that automatically builds a database and tags images based on deepbooru. the problem I have with it is I want it to run through the deep booru database files multiple times. so for example, a pony, or fetish, or pixel art, WAIT, or even OCR pass could all be done in turn for each image if it could only be programmed to do this. As it is right now it does everything it already needs to do per say, but if you want to use more than one AI database, you are forced to either Rebuild another database with its own set, or abandon the functionality of the deepbooru model you replaced with another.

Ideally this thing could be expanded to tag just about anything, and when I tested it, it ran on pretty outdated hardware pretty respectably. I tried asking around on twg but no one there wants to do commission based work. I really feel like we've been sleeping on this as an entire board. We deserve to have the best image sorting software at our fingertips, and it's honestly halfway built for us, but I am not a programmer, and i dont really have time to do it.

https://github.com/k1rak1ra/FEMBOY

I'd like to commission someone to do that, I'll be releasing the fork under a pretty permissive loisance and i dont really plan to sell it, but I do want to include some anti censorship based license amendments.

>>103213519

>>103213585

i've decided to give up on becoming a programmer for the check.
i just want to make stuff now. can i just focus on just one language (i know C++ kinda from school and C# from unity) or should i learn other ones like python and js in case the situation calls for it? like if I needed to use a library written in python.

modern C++ is as old as the language itself. for example, my copy of picrel is pre-C++11 and uses type lists to achieve what you would use variadic templates for today. the language had evolved, but these concepts were known long before C++11. doesn't matter what you call them: modern, effective or whatever.

In programming, f(x)f(x) is a mathematical notation commonly used to represent a function. Here’s what it generally means:

Function Name and Input:
ff: The name of the function.
xx: The input (or argument) passed to the function.

For example, f(x)f(x) means a function ff takes xx as an input.

Output:
f(x)f(x) returns some value based on the computation defined within the function.

Example in Programming

Here’s how f(x)f(x) translates to code in popular programming languages:
Python

def f(x):
    return x * 2  # Example of a function doubling the input

result = f(5)  # Calling the function with x=5
print(result)  # Output: 10

JavaScript

function f(x) {
    return x * 2; // Example of a function doubling the input
}

console.log(f(5)); // Output: 10

General Purpose:
Encapsulation: Functions like f(x)f(x) encapsulate a block of code, making it reusable.
Abstraction: Helps abstract details by focusing on the input and output relationship.
Mathematical Representation: f(x)f(x) can represent mathematical equations, transformations, or real-world models.

If you have specific contexts in mind, feel free to share, and I can provide a more tailored explanation!

maybe. personally, I would have hard time going back to anything older than C++17 (mostly because of if-constexpr). giving up concepts would be painful too (C++20). when I said modern, I actually meant modern.
