sauce, this is super comfy

its not hard to make a webm you know. Just use ffmpeg with screen as input and unmodified file as output, then slice and format the relevant part of the media into a webm and post it.

link to archive?

Or share your discord scrapper.

Either one.

Writing a program that is a Vigenere Cipher.

The algorithm I found for it is:
Ei = (Pi + Ki) %26 + 'A'

I keep getting the wrong results. Even if I try something simple like

E = (i + b)%26 + 'A' I am expecting to get "J", but am instead getting "V"

What's the correct formula to do this?

Scraper itself is a bit trash and only written for the specific task
basically what I had done was copy & pasted a bunch of images from sancom (and a few other places) into discord, and since I'm on macOS it pasted PNG versions because of course
so the scraper went through and for every filename (which macOS luckily preserved) it used that to look up the pics on sancom by MD5 and download the original
there were a few odd ones where I had to hard-code the MD5 filename, the whole thing is a hack and not very good code
I can still gist it if you want

I'm literally still just calling the generator function manually, pic related is the current state

Newbie about to start self-teaching here, what texts would be good to start learning, primarily Java/C#/C++/JS? I want to at least try and get something when I graduate in 6 months, and I've heard these are the most feasible options for myself who has little programming experience.

Why does it seem like every fucking post in these threads is written by a freshman CS nerd who literally has no idea what they're doing? Where are the people who actually do useful shit?

It's about Game Dev Lolis

define "useful"

Anything that is not a weekend project that you write to learn the very basics of a programming language, no shitty fizzbuzz or chatbots or other retarded shit.
Something that actually has contributions, unit tests, open issues on a github repository, people using the software, etc.
You know, real software development, not first year undergrad stuff.

/dpt/ are largely amateurs/cs students/hobbyists. I don't know where you got an idea otherwise. And then i ask, where's your useful software?

>/dpt/ are largely amateurs/cs students/hobbyists.
Yes, that's what I'm talking about. It's garbage.
>where's your useful software?
Nice whataboutism, unrelated to the conversation.

Deciding between two different architectures for part of a project - one uses SQLite and the other uses PostgreSQL. Also wondering if it might be worth the effort to pillage code and ideas from Fossil or if it would be less awkward to design something native, in-house.

It's not. If you bitch about a lack of X, but have none to contribute to the thread yourself. Then you're just as bad, if not worse.
But enough meta shit.

Maybe I'd contribute to the thread if I were people at my level of knowledge to talk with, rather than a bunch of undergrad students in their basements.

Most of them probably try to avoid people like you.

Cat, improved

Its called catm, im going to add syntax highlighting and stuff

You dont seem to have a super firm grasp on the difference of markov chains and NNs

>18-19
thats fine
>they look like 12yos though
what do you expect from the worlds most perverted people?

aren't you essentially just making a CLI TE at this point?

I work at a gamedev company and I can confirm that my coworkers look exactly like this.

>Cat
>improved
oh no no no no...
*laughs in bloat*

M_i + K_i % 26
Where M_i is the ith chunk of a message and K_i the ith key or cipher. Both i not necessarily equal, just repeating evenly against each other to permit decryption.

Also just implement any cipher and youre kinda done. Ciphers like these are horribly weak against a calculator.

A conCATination tool should not be highlighting fucking anythinv

that's why you should use getopt

Why is C++ IO so much shittier than C IO?

Why do you waste your life doing shit like that?

maybe it's homework

Is programming in Rust the path to becoming a cyber vegan or a data pagan?

I thought you needed to be over 18 to post on this board.

college homework

>Is programming in Rust the path to becoming a cyber vegan or a data pagan?
Yes.

A markov chain is BASICALLY just a single node neural network. Or to be a little less inaccurate, they both rely on probability networks. Markov chains just dont think about the past or future in their probability while a NN might.

Tl;dr im being a pedantic cock

Too much disagreement on an STL implementation, same reason std::string isnt implicitly converted to const char* by the compiler when necessary despite it having an infallible function to do so.

>A markov chain is BASICALLY just a single node neural network. Or to be a little less inaccurate, they both rely on probability networks. Markov chains just dont think about the past or future in their probability while a NN might.
lmao no

I mean I guess you can think about it that way, but most people think of Markov chains as something that uses the last N values to predict a next value, while they think of NNs as magic input->output devices. My description just clarifies how I'm trying to use the NN.

getopt doesn't support non -option if your option have different flag other than -, the only way is by write it yourself

Except Markov chains have literally nothing to do with neural networks whatsoever.

I'm the chatbot guy not

I don't give a shit who you are, this is an anonymous website, not reddit or your tumblr.

ignoring post context won't help you build a good markov chain

listennn I have the most difficult c++ problem

const int *a = {blablabla};
const int *b = {blebleble};

int *c = a;

what kind of hurdles will i run into if i decide to write a disassembler? how could i go about testing a processor emulator in a meaningful way? i'm really interested in writing an emulator for one of the old intel or zilog processors, but i'm not sure what i could *do* with that project once i've completed it

learncpp.com
use it
learn it
complete it

Use for dumb questions.

const int *c = condition ? a : b;

you need a const_cast in there

int const *c;

non const pointer to const data

That's the same as this
const int *c

What it should be is this
[code
int * const c

Been interested in NNs and the like for awhile now, you have any good resources on how to get into it?

sounds like you need a long-term project you're interested in. I'm always thinking about mine and i don't even play that much vidya anymore because of it.

this thread has more posts that are actually related to programming, tankie

not really, I'm basically making this shit up as I go based on my recollections of learning it years ago in a single college course

>>implying a cartoon makes me feel anything
hmm if you have trouble connecting to abstract realizations of humans you might be on the spectrum

because you couldn't keep Jow Forums in Jow Forums

I didn't make that thread, retards.
but again, it only shows your hypocrisy. anime in the OP? no problem. political propaganda you don't like? destroy the thread.

Child sexual abuse is very serious, and a lot of people abused by priests spend years trying to cope with what happened to them. Pretty fucked up that you would use that for cheap point scoring in on an internet anime image board.
