    Do you ever feel like 15 byte limit for interface names on Linux is annoying? I have a solution for you: use emojis. Hotdog as a word is 6 bytes, but 🌭 is just 4! 👨‍🔬

    Texas is so welcoming, you get stopped by border patrol twice in one night after visiting a national park. As an alien I was supposed to carry my green card in addition to my California DL I fly on 🤷‍♂️ A friendly lady on the first stop even printed us a law
