Great to hear that you’re looking to get into PostmarketOS development! I recommend taking a phone that’s already supported, using it and then figure out how improve support the device.

Porting/Mainlining a new device is also possible but that can be demotivating if it doesn’t work and it’s generally harder to get started with.

If you have any questions or need help you can dm me and I can help.

Ich möchte gerade einen Treiber für einen controller schreiben, bei dem die register map nicht im Datenblatt steht. Das heißt ich darf den Android treiber für diesen chip reverse-engineeren und probieren rauszufinden wie es funktioniert.

I went all-in on proton a few years ago but I dislike the direction in which they are going now. Does anybody have tips on how (and where) to switch smoothly. I could self host email but I’ve heard that it’s a big hassle

Why? Do you live in america or something where bus infrastructure is bad?

Only after the last tree has been cut down
Only after the last river has been poisoned
Only after the last fish has been caught
Then will you find that money cannot be eaten.

I think it should be possible with a reverse proxy. I don’t see why not

School food ruined so many things for me. I used to hate rice and gyros but they are really tasty if prepared well

Android definitely has encrypion, but it is just the user data not the programs. It you ever run mount on an android device you will see that it has lots of different partitions for that sort of stuff

What does wayland support mean in the context of vim? Like wayland clipboard or what?

I actually did this. It did not end up being any faster than the brute-force solution since it seems to only catch the easy cases

You’re using the meme wrong. The “at home” needs to be worse than the “mom can we get?”

Weiß ja nicht. Alles was ich von Staiy mitbekommen habe ist, dass er sich oft über dinge aufregt. Aber das kann sich ja auch geändert haben

Rust

Pretty happy with my solution today. I took my time today as it was a bit of a slow day and did it in Rust instead of python. Having proper Vec2 types is very nice.

use std::{collections::HashMap, error::Error, io::Read};

use glam::{IVec2, Vec2};

fn permutations_of_size_two(antennas: &[Vec2]) -> Vec<[&Vec2; 2]> {
    let mut permutations = vec![];
    for (i, antenna) in antennas.iter().enumerate() {
        for j in 0..antennas.len() {
            if i == j {
                continue;
            }
            permutations.push([antenna, &antennas[j]])
        }
    }
    permutations
}

fn main() -> Result<(), Box<dyn Error>> {
    let mut input = String::new();
    std::io::stdin().read_to_string(&mut input)?;

    let height = input.lines().count() as i32;
    let width = input.lines().next().unwrap().len() as i32;

    let antenna_positions = input
        .lines()
        .enumerate()
        .flat_map(|(y, l)| 
            l.chars().enumerate().map(move |(x, c)| (Vec2::new(x as f32, y as f32), c))
        )
        .filter(|(_v, c)| *c != '.')
        .fold(HashMap::new(), |mut acc: HashMap<char, Vec<_>> , current| {
            acc.entry(current.1).or_default().push(current.0);
            acc
        });

    let mut antinodes = vec![];
    for (_c, antennas) in antenna_positions {
        let perms = permutations_of_size_two(&antennas);
        for [first, second] in perms {
            let mut i = 1.;
            loop {
                let antinode = (first + (second-first) * i).round();
                if (0..height).contains(&(antinode.x as i32)) &&
                    (0..width).contains(&(antinode.y as i32)) {
                        antinodes.push(antinode);
                } else {
                    break;
                }
                i += 1.;
            }
        }
    }

    let mut antinode_count = 0;
    let map = input
        .lines()
        .enumerate()
        .map(|(y, l)| 
            l.chars().enumerate().map(|(x, c)| {
                if antinodes.contains(&Vec2::new(x as f32, y as f32)) {
                    println!("({x},{y})");
                    antinode_count += 1;
                    return '#';
                }
                c
            }).collect::<String>()
        )
        .collect::<Vec<_>>()
        .join("\n");

    println!("{map}");
    println!("{antinode_count}");

    Ok(())
}

My initial comment was a bit harsh, I’m sorry for that. It was meant to be a bit of a joke. Anyway here’s my code. Do note that I don’t do the challenges timed so I have a bit more time to name my variables accordingly. Takes 35 seconds to run on a pc with a AMD Ryzen 5 5600

import sys
from tqdm import tqdm


input = sys.stdin.read()

def all_operator_permutations(operator_count):
    if operator_count == 0:
        return [[]]

    smaller_permutations = all_operator_permutations(operator_count-1)
    return [
            *[['+', *ops] for ops in smaller_permutations],
            *[['*', *ops] for ops in smaller_permutations],
            *[['||', *ops] for ops in smaller_permutations],
            ]

def test_operators(ops, values):
    res = values.pop(0)
    for op in ops:
        match op:
            case '*':
                res *= values.pop(0)
            case '+':
                res += values.pop(0)
            case '||':
                res = int(f"{res}{values.pop(0)}")
    return res


total_calibration_result = 0

for line in tqdm(input.splitlines()[:]):
    target, *tail = line.split(':')
    target = int(target)
    values = [int(val) for val in tail[0].split()]

    all_perms = all_operator_permutations(len(values) - 1)
    ops = all_perms.pop()
    while True:
        res = test_operators(ops, values.copy())
        if res == target:
            total_calibration_result += target
            break
        if not all_perms:
            break
        ops = all_perms.pop()

print(total_calibration_result)

What a horrible way to name variables
