  • Problem with plain Wireguard is if you can’t open ports on some devices to get a direct connection. It should be just fine with hub and spoke model, but NAT Traversal of Tailscale makes a huge difference. I can get a direct connection between 2 devices connected to mobile data and behind CG-NAT.
    And also the config management if you have too many devices.

    Hub and spoke, you just add new devices to Wireguard on the main device, and the new peer. Full mesh, oof.

    But as far as configuring Wireguard goes, that’s pretty simple. And then there’s the weird stuff with MTU and fragmentation… but that’s not something Wireguard-specific.












  • I used to do absolutely everything on my phone, until I got a ThinkPad.

    But yeah, I went from a terrible HP that had SMR HDD and a TN panel where I constantly had to move my head depending on what I wanted to read because it had no contrast to 2-in-1 ThinkPad with pretty nice touchscreen IPS and NVMe SSD that I can charge with the same power bank and wall adapter I use for my phone.

    I am not really joking with that screen. When I wanted to do something beyond text, I’d either connect it to TV, or use a HDMI USB capture card connected to my phone.




  • High pitched noises sometimes. I have an audio spectrum visualizer app installed to confirm these. But they can be pretty weird as they bounce around. You’ll get these heat spots. Unfortunately, I feel like my ears are degrading now.

    Anyway, dimmable LED lights are often a problem due to PWM. Only full brightness is quiet.

    Smell, I don’t even know what the hell that was. There is or was something in the back of one bus. I wouldn’t say it’s smell, but… something. Just a spicy punch that doesn’t quite let me breathe in. I noted down the license plate if I’ll experience it again to confirm it’s the same vehicle, but this wasn’t the first time, though unfortunately I didn’t copy it that first time. Same line though, so possibly same vehicle as well.
    But I am not sure if I was the only one, no one was visibly bothered, but who knows.
