    Nobody cares what happened to Rust in the last 3 months of 2019, including Rust 1.39 and Rust 1.40 release notes. All because dates are hard if you don't do ISO8601 🕘 Exhibit one:

    If you are into legacy IPv4, you're out of luck. Most of the good 4 byte emojis start with 0xf0, which means that their IPv4 address lands into reserved 240.0.0.0/4 ☹️

    You can also pack emojis in binary IPv6 representation. In /64 prefix your ISP gives you it's possible to fit up to two emojis 😎 Please excuse me while I rewrite some MACs to get 2604:5500:c2f1:ff01::☕️ assigned to my coffee maker.

    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

    My new internet didn’t have IPv6, so I asked ISP to fix it. The fix included /56 delegation and broke my IPv4 gateway. Let me tell you: it is very lonely on IPv6 only internet. Alexa 500 is only ~16% available (twitter itself is not).
