That's exactly why you want to do this. When people speak casually or are making jokes, nobody speaks with grammar in mind. Gathering this intuition for the language is exactly what I'm looking for when learning.

You just look for people who are interested to learn your language, any place where people communicate can work. Maybe hit some groups for learning the language you know and try to find people who speak the language you want there.

I personally play VRChat, there are a number of language learning groups there. Though, the culture of the place is certainly not for everyone.

Not really about piracy, but doing language exchanges is a great way to learn a language. You teach someone your language, they teach you theirs. It's free and it gives you more knowledge than any book. Natural languages don't work with strict rules usually, natives speak by feel, the only way to learn that feel is by interacting with people.

I don't like the last part.

While I see the analogy, saying "CachyOS to Arch is like Ubuntu to Debian" with a straight face is not something I can do. If you try to interact with an Ubuntu install like it's Debian, you'll get very frustrated very quickly. If you try to interact with a CachyOS install like it's Arch, you probably won't even notice you are not on Arch, besides a couple of different package names.

They use their own repos, but they don't hold back the packages. The reason for having separate repos is recompiling packages for newer architectures. It gives a little performance boost for most of them. AUR works totally fine.

So, you are telling me I'm free to try and then just return to where I was if something goes wrong?

Wouldn't say I use it often, but this thing resolves a domain name to an IP address:

function resolve() {
  case $1 in
    -4)
      getent ahostsv4 $2 | grep STREAM | head -n 1 | cut -d ' ' -f 1
      ;;
    -6)
      getent ahostsv6 $2 | grep STREAM | head -n 1 | cut -d ' ' -f 1
      ;;
    -p)
      getent hosts $2 | head -n 1 | cut -d ' ' -f 1
      ;;
    *)
      getent ahosts $1 | grep STREAM | cut -d ' ' -f 1 | sort -u      
      ;;
  esac
}

All my aliases are just default arguments for programs or shorthands for my other scripts, most of which are specific for my setup.

This is a very good argument for ffmpeg and ffprobe, by the way:

alias ffmpeg="ffmpeg -hide_banner"
alias ffprobe="ffprobe -hide_banner"

BitTorrent breaks your data in blocks, each block is hashed, their sizes are known. Assuming you got your .torrent file from a legitimate source, it's practically impossible to receive something else, as long as your client does all the checks properly.

In theory, it is possible to write malware that will collide hashes with some other content, but considering you are restricted to the size of the actual content, it's extremely unlikely that out of all the millions of .torrents we created so far we can find even one for which it is possible.

And even if you win this absolutely bizzare lottery, you'll be competing with legitimate peers for serving the blocks. If at least one block that you care about is not served by you, the recepient will just get corrupted content that won't be dangerous in any way. In other words, you need to have so much bandwidth, that you serve everything before anyone else can serve even one significant block. At which point you will probably have to spend a lot more money on that than you'll ever get from whatever malware you are trying to serve.

.for_each(|((_, _, t), (_, _, b))| { ... }

This is actually fairly similar to what C# has.

This is a closure syntax:

| arguments | { calls }

In C#, the closest is lambda expressions, declared like this:

( arguments ) => { calls }

Parentheses are tuple deconstructors. In C# you have exactly the same thing. Imagine you have a method that returns a two element tuple. If you do this:

var (one, two) = MethodThatReturnsATuple();

You'll get your tuple broken down automatically and variables one and two declared for you.

First of all, I'm using .zip() to pair the rows of the picture by two, that returns a tuple, so, I have to deconstruct that. That's what the outer parentheses are for. The pixel enumeration stuff I'm using returns a tuple (u32, u32, &Rgba<u8>) first two values are x and y of the pixel, the third one is a reference to a structure with color data. I deconstruct those and just discard the position of the pixel, you do that with an underscore, same as C#.

I'm not that far into learning myself, but I'm not a textbook learner at all. Poking around opensource projects and wrestling with the compiler prooved to educate me a lot more.

As an extra optimization, if top and bottom colors of a pixel match, you can just output space and only set background color. Implemented correctly, this can save a lot of memory. Didn't want to make the code more complex in fear of people being scared of running it.
