I'll agree with your bait because I'm too lazy to properly learn the other two.

Okay, I'll bite on this bait and WILL move the goalpost: you are too retarded to have any discussion and therefore I win by default.

>>105764133 (OP)
It's nothing programming related this time but I'm finishing my book about topology and manifolds. I've been writing it since 2023 and It's finally getting ready.

I write it using LaTeX + vscode + git. Diagrams are made using mathcha.io

I'm writing a trading agent and people and slopbots talk about "State pattern". My finite state machine works, but it is based on trasition objects which have to and from states, condition to transit and action to take when transitioning.

Each agent has that list created when it is instantiated.

Apparently it violates the "open closed" principle, and "separation of concerns", but it's pretty much a 1:1 mapping of what a FSM is.

I am getting filtered by this Design pattern stuff.

>>105765219

>>105765537
I think you should detransition before it's too late.

>>105765537
>I'm writing a trading agent
Yeah, I figured that's what you meant when you wanted to make sure your program doesn't crash.

>>105765565
Currently I only do back-testing with it. Its not connected to anything. Do you mean "state pattern" has a tendency to crash?

>>105765589
Aren't you the guy from a couple threads ago who wanted to know in which language he should write a program that wasn't allowed to crash, lest you lost a lot of money?

>>105765608
Not really. I am writing it in common lisp, R and python. Most of the logic is in CL.

>>105765537
>>105765616
(letrec ((s0 (lambda (t)
(case t
('end 'accept)
(0 s0)
(1 s1))))
(s1 (lambda (t)
(case t
('end 'reject)
(0 s2)
(1 s0))))
(s2 (lambda (t)
(case t
('end 'reject)
(0 s1)
(1 s2)))))
...)

>>105765737
yeah, literally this but more complex. Apparently this is not "clean"?

>>105765793
If letrec contains no side effects and s0 is returned as a start state I can't imagine how it could be better encapsulated

>>105765834
>>105765737
I'm referring to design patterns, some people have commented my code is not "clean".
I don't work professionally, so I don't know what that means or why I need to use "patterns".
I've removed the error handlers, and a lot of other things that make it work the way I want:

(defclass event ()
((message :accessor message :initform nil :initarg :message)
(timestamp :accessor timestamp :initform nil :initarg :timestamp)))
;;; Base agent class, must be subclassed
(defclass fsm ()
((state-history :initform nil
:initarg :state-history
:accessor state-history)
(transitions :initform nil
:initarg :transitions
:accessor transitions)
(current-state :initform nil
:initarg :current-state
:accessor current-state)))

(defclass transition ()
((from-state :accessor from-state :initform nil :initarg :from-state)
(to-state :accessor to-state :initform nil :initarg :to-state)
(action :accessor action :initform (lambda () nil) :initarg :action)
(allowed? :accessor allowed? :initform (lambda () nil) :initarg :allowed?)))

(defmethod update ((fsm fsm))
(with-slots (current-state state-history transitions) fsm
(let* ((transition
(loop for tr in transitions
when (and (equal (from-state tr) current-state)
(funcall (allowed? tr)))
return tr)))
(if transition
(progn
(with-slots (action to-state) transition
(funcall action)
(push to-state (state-history fsm))
(setf (current-state fsm) to-state)))
(error 'no-valid-transition)))))

(defmethod consume ((fsm fsm) (event event))
(when (observe? fsm event)
(sense fsm event)
(update fsm)))

>don't use objects or OO
My life is 100% easier with CLOS than juggling lists around for the things I'm doing.

>>105765894
>some people have commented my code is not "clean".
ask them to point out what specifically is not clean
>why I need to use "patterns".
patterns are tried solutions to common problems, if the problem you're having fits exactly to what the pattern fixes
if someone tells you to shoehorn a design pattern when it doesn't make sense for the case, call him a fag and stop listening

not a lispfag so I read your code after copilot translated it to java (good morning sirs) and I don't see anything egregious about the solution
only thing you could possibly change (evaluate yourself if it's worth it) is to add the list of valid transitions to each state object
so you would have:
>state contains its name and a list of valid transitions from itself
>transition contains the target state and transition action
>fsm gets transitions from its current state value rather than a separate parameter, and executes the action for each transition
that way you don't need the extra condition to check if a transition applies to the current state - if the state has it, it is applicable

I have no use for data or "querying" it.

How do I properly architect internals of a library that implements the parsing and the logic for a network protocol (that runs on top of TCP+TLS)? I don't want to end up with some kind of spaghetti code where I have I/O, parsing and logic all mashed together in functions. Any architectural patterns that could help?

This, but unironically.

>>105771085
Had modules been priority 1 since its inception we wouldn't have template hell in headers regenerating and recompiling everything everywhere and Go wouldn't exist.

>>105771249
Modules don't solve this.

>>105771085
Indeed, a treat for both the eyes and the fingers.

>>105771259
The Header-Based Template Problem
Traditionally in C++, templates are defined in headers because the compiler needs to see the full implementation at the point of instantiation. But this means:

Every translation unit that includes that header re-parses and re-instantiates the template.

This leads to longer compile times and redundant code generation.

How C++ Modules Help
C++20 modules tackle this by offering a smarter, more efficient system:

One-time Parsing: When you import a module, the compiler uses a precompiled binary representation of it. So the compiler doesn’t have to re-parse and re-instantiate the template every time.

Template Instantiation in Modules:

If a template is defined in a module interface, it can still be instantiated by importing translation units—but only the instantiations that are actually needed.

If you define and explicitly instantiate templates inside the module implementation, those instantiations can be compiled once and reused across TUs—effectively hiding the implementation details.

Improved Encapsulation: Since implementation details (including templates) can be defined in the module’s private partition, they don’t leak across the entire codebase like headers do.

Gippity says otherwise, chud.

you don't need templates

>>105771368
And I say that you created this hell by using templates everywhere even when you don't actually have to.

>>105771368
Don't fucking post ChatGPT spam here.

>>105771405
This. I never use templates. Shit fucking sucks.

you will use templates

>>105772161
yeah they're pretty good when you're in a good language

you will use x headers

Modules never ever.

My C++ code generates identical assembly to C. I only had to disable exceptions, rtti, and standard library (reminder: libc is just as shitty if not shittier that libc++, it's worthless and I disable it too). I use templates and classes, just works on my machine, nocoders will find a way to have a melty over that though.

Your made-up situation fails because I also found the finally helpful function-pointer instruction "a google search away"
You're eager to assume that I have a strong external locus of control, I wonder why.

in C++ is this an appropriate scenario to use a base / derived class and if not, what would be a better alternative?

IDevice
init
read
write

Device0
Device1
...
DeviceN


99% of Device implementations will implement init, and read, a lot won't implement write, and 1% may not have init or read.

I want to be able to just store them all in a Device array and iterate over and call read / write on them all (if the function is present) and also call init on them when I push to the array (again if present). I don't want to maintain 6 separate arrays and/or 6 separate derived classes for each device-function combos and I want some enforcement on using the same pattern on the functions for all implementations.

>>105784788
why are you even doing this? if you can't understand pointers how do you plan on understanding actually advanced concepts? or when your only documentation is the actual documentation, or even worse, the source code? you clearly have learning disabilities and a victim complex

This is just a hobby for me, my work is math/stats, I have no need to look at source code, sometimes documentation but mostly python/R. I'm not sure what you consider 'actually advanced concepts', but if I can be a little rude in response to your rudeness: it's probably a bit paint by numbers, honestly.

>I spent my whole life optimizing a registry dumper and best it can dump at is 50MB/s and it's worthless
Meanwhile vibecoder spent 2 days using new technology as a gaming console just for lulz and he didn't even need to do anything because LLM did most work for him. I'm sure if you spend another decade on your registrydumping, you might be able to upgrade to 51MB/s dumping, while vibecoders will be programming autonomous asteroid mining bots.

There's no reason to need any languages other than C++23 and Javascript. You can do 99% of everything with those two. Arguably basic bash knowledge if you want do a little scripting, but LLM does that for you now with near 100 percent accurately.

>incompetent autistmo has to make shit up to protect his fragile ego

You needn't worry about your fragile ego. I'd rather worry about your fragile bones. They'll break a lot in your upcoming, yet short future.

Well, at least you'll never be employed in a meaningful position, so that's that.

Although, now that I think about it ... they told me autismos can also barely tell if someone is lying to them, so they usually believe stuff at face value. You probably actually believe that I spent an entire life writing the registry dumper because the incompetent autismo master said so.

That's grim. I mean, ADHD can be fixed with medication, but autism just cripples you.

>>105789205
Can you tell me why you need to be told that a program exists that does just that and writing a script for it is so retarded that LLM assumed that you're just trying to learn about filesystems and not that you're mentally ill enough to use it on your NAS?

Ultimately I want to create a little GUI where I can select from a pair of dropdowns a device and the port I want to add it to, then I can plug in the device and it will just work because the system has configured it on object creation and is read/writing in whatever manor it needs to for that specific device.

Main thing I'm thinking of right now is how to identify each device so that manager can find a specific one again later. Also I don't like the duplication of the listAllowedPorts function on each derived class but I don't know a way around that

I am pretty sure that there is no difference between doing a unity build by hand vs the cmake unity build, other than avoiding cmake (it's a pain but vcpkg or whatever flavor you prefer is worth it since vcpkg will copy all your DLL's to your binary, you can even use it with msys2 but I don't see the point since you are missing out on address sanitizer on msvc, and clangd works on msvc on clion which has a free non commercial license).
I'm still waiting for my project to get big enough for build times to matter.
also precompiled headers are an option.
I believe to use precompiled headers you can just use headers the normal way, and cmake just adds the precompiled header while building.
Also you should include all your headers, if you don't, it breaks clangd because it expects all files to be complete (you can't assume something is included before the file, the file needs to include everything that it uses).

What are some good project ideas to learn kubernetes?

>>105799297
Serverless registry dumper.

>>105799297
there is nothing good about using kubernetes, ever

>>105799317
Can you provide an example?

>>105797039
what do you do when your function encounters an error? there are times when returning a default value and/or throwing an exception are not ideal

>error C1128: number of sections exceeded object file format limit: compile with /bigobj
I think I went too far with metaprogramming bros

>bro why are the only datatypes in this entire shitty language string, number, and table?
A string is a table where key-value pairs represent string indices and characters, a number is a set of tables representing sign, decimal, fraction or exponent as a series of nested tables

>but what about like, idk, lists or dates or whatever
A list is just a table where each value is the index of a key, a date is a table of n rows for each second since 1970-01-01

>you realize it's current year right?
The current year is 1751642088 tables

Sorry, I'm not employed enough to know how to spin up Windows Server 2003 on kubernetes.

>>105799847
You and your suggestion are useless.

>>105799896
So is kubernetes.

>>105799903
People employ it though, unlike you.

>>105799914
The difference is that I am not retarded.
