Go

Part 1, just find the regex groups, parse to int, and done.

func part1() {
	file, _ := os.Open("input.txt")
	defer file.Close()
	scanner := bufio.NewScanner(file)

	re := regexp.MustCompile(`mul\(([0-9]{1,3}),([0-9]{1,3})\)`)
	product := 0

	for scanner.Scan() {
		line := scanner.Text()
		submatches := re.FindAllStringSubmatch(line, -1)

		for _, s := range submatches {
			a, _ := strconv.Atoi(s[1])
			b, _ := strconv.Atoi(s[2])
			product += (a * b)
		}
	}

	fmt.Println(product)
}

Part 2, not so simple. Ended up doing some weird hack with a map to check if the multiplication was enabled or not. Also instead of finding regex groups I had to find the indices, and then interpret what those mean... Not very readable code I'm afraid

func part2() {
	file, _ := os.Open("input.txt")
	defer file.Close()
	scanner := bufio.NewScanner(file)

	mulRE := regexp.MustCompile(`mul\(([0-9]{1,3}),([0-9]{1,3})\)`)
	doRE := regexp.MustCompile(`do\(\)`)
	dontRE := regexp.MustCompile(`don't\(\)`)
	product := 0
	enabled := true

	for scanner.Scan() {
		line := scanner.Text()
		doIndices := doRE.FindAllStringIndex(line, -1)
		dontIndices := dontRE.FindAllStringIndex(line, -1)
		mulSubIndices := mulRE.FindAllStringSubmatchIndex(line, -1)

		mapIndices := make(map[int]string)
		for _, do := range doIndices {
			mapIndices[do[0]] = "do"
		}
		for _, dont := range dontIndices {
			mapIndices[dont[0]] = "dont"
		}
		for _, mul := range mulSubIndices {
			mapIndices[mul[0]] = "mul"
		}

		nextMatch := 0

		for i := 0; i < len(line); i++ {
			val, ok := mapIndices[i]
			if ok && val == "do" {
				enabled = true
			} else if ok && val == "dont" {
				enabled = false
			} else if ok && val == "mul" {
				if enabled {
					match := mulSubIndices[nextMatch]
					a, _ := strconv.Atoi(string(line[match[2]:match[3]]))
					b, _ := strconv.Atoi(string(line[match[4]:match[5]]))
					product += (a * b)
				}
				nextMatch++
			}
		}
	}

	fmt.Println(product)
}

Really cool trick. I did a bunch of regex matching that I'm sure I won't remember how it works few weeks from now, this is so much readable

Go. I actually I haven't written a single line of Go since last year's AoC so it's a good excuse to go again (pun intended).

I liked Digital Minimalism by Cal Newport. I found myself reaching for my phone more often than I would few years back, and doomscrolling at nights, and I got some good tips from this book.

I wouldn't say it solved all of my issues and I will be taking a look at the other books recommended here. But it did help me reduce screen time and focus more on tasks without feeling that I have to look at my phone every 5 minutes.

Dragon Ball characters, named Bibidi, Babidi and Boo, respectively.

(Ok the last one is called Majin Boo but he's referred as Boo too)

Good

Tbh these don't even look that bad. Even many times you peel one of these and they are totally fine on the inside

Cosmo and Wanda don't fool anyone nowadays

I feel you. And I work in tech (maybe you do too, idk). Point is, I'd need a bicycle AND a career change...

Oh whaat, hell yeah! Definitely gonna be having a look at this, thanks for sharing.

Still want that remake tho haha

I want a remake of the original Harry Potter 1 and 2 games from the PS1. Not asking much, anything that looks nicer than this would do

Taringa, it was the go-to place for everything, especially content in spanish
