    Guess I’m a bit late on day one. Wound up doing mine in go, but maybe if I’m motivated I’ll use something cooler later. Those elixir solutions are rad!

    part 1 
    func main() {
	b, err := os.ReadFile("input.txt")
	if err != nil {
		log.Fatalln(err)
	}

	d, err := distance(string(b))
	if err != nil {
		log.Fatalln(err)
	}
	fmt.Println(d)
}

func distance(input string) (int, error) {
	var left []int
	var right []int
	for _, line := range strings.Split(input, "\n") {
		fields := strings.Fields(line)
		if len(fields) != 2 {
			continue
		}

		l, err := strconv.Atoi(fields[0])
		if err != nil {
			return 0, err
		}
		left = append(left, l)

		r, err := strconv.Atoi(fields[1])
		if err != nil {
			return 0, err
		}
		right = append(right, r)
	}

	slices.Sort(left)
	slices.Sort(right)

	var total int
	for i := 0; i < len(left); i++ {
		total += int(math.Abs(float64(left[i] - right[i])))
	}

	return total, nil
}
    part 2 
    func main() {
	b, err := os.ReadFile("input.txt")
	if err != nil {
		log.Fatalln(err)
	}

	s, err := similarity(string(b))
	if err != nil {
		log.Fatalln(err)
	}
	fmt.Println(s)
}

func similarity(input string) (int, error) {
	collisions := make(map[int]int)
	var left []int
	var right []int
	for _, line := range strings.Split(input, "\n") {
		fields := strings.Fields(line)
		if len(fields) != 2 {
			continue
		}

		l, err := strconv.Atoi(fields[0])
		if err != nil {
			return 0, err
		}
		left = append(left, l)
		collisions[l] = 0

		r, err := strconv.Atoi(fields[1])
		if err != nil {
			return 0, err
		}
		right = append(right, r)
	}

	for _, r := range right {
		c := collisions[r]
		collisions[r] = c + 1
	}

	var total int
	for _, l := range left {
		v := collisions[l]
		total += l * v
	}

	return total, nil
}

    Reasonably okay (but maybe don’t get the absolute newest model), but not as good as the others which are all excellent. I mostly put them in the list because they’ve got excellent build quality, good keyboard, trackpad, etc, and a very nice screen. Basically if you want a macbook with linux (for cheaper than a macbook with linux https://asahilinux.org/) they’re pretty reasonable. They also support openbsd which is neat https://jcs.org/2021/08/20/matebook

    The laptops I listed are in order of preference imo. Framework is definitely in a class of itself, but if they don’t ship to your country or something then getting an xps with linux pre-installed is great and then finally as a backup either a thinkpad or matebook.

    Framework for sure, specifically the 13 with the new higher res screen. It’s a perfect 2x scale which is really nice.

    The older screen is fine, but some older x11 programs will be scaled wrong.

    There are other nice laptops of course: dell xps, thinkpad x1c, huawei matebooks, but imo the framework laptops are better in most regards and as a bonus you can upgrade the ram, cpu, and motherboard without needing to buy a new computer. You also can buy them without a windows license which usually makes them cheaper than the others for similar specs (unless you’re going for used of course).
