  • Time to turn your laptop into a router! Let’s say you’ve got 2 network interfaces on your laptop, eth0 and wifi0. wifi0 is joined to your university WiFi as normal. Connect your iPad to your laptop via ethernet (with a USB-C adapter).

    iPad -> usb-c-ethernet -> eth0
    wifi0 -> internet
    

    Rather than setting up a DHCP server or IPv6 stuff, I’d just configure the wired interfaces manually. Let’s use the network 192.168.69.0/24. Laptop will be 192.168.69.1, iPad will be at 192.168.69.2. On the laptop:

    ip addr add 192.168.69.1/24 dev eth0
    

    On your iPad, go to Settings -> Ethernet:

    • address: 192.168.69.2
    • subnet mask: 255.255.255.0
    • router: 192.168.69.1

    Curious to see if that works. We haven’t set up DNS or DHCP or done any sysctl for IP forwarding or any nftables.

    How can we test if it works? We can set up a TCP listener using nc(1) on the laptop that the iPad’s web browser could hit. On the laptop:

    nc -l 8080
    

    On your iPad, open Safari and browse to http://192.168.69.1:8080

    Curious to see if that all works!

  • On reddit and now lemmy, I can engage with other people in both appreciation and discussion on and about things I don’t really get to otherwise, at a depth I don’t really get to otherwise.

    Nicely worded. The microblog format never “clicked” for me the same way these threaded discussions do. Now I have a way to say why - thanks!

    I think if I was born in a different decade I would have enjoyed Usenet or mailing lists.






  • I think IRC is a bit healthier because it is a direct interaction and there is no upvotes or any fake internet points involved.

    Totally see what you mean. The points and “likes” can be tiring. In a Lemmy client I made, I don’t even bother rendering the votes. This helps. But I havent implemented threaded replies (yet?).

    If there was a way to interact with Lemmy more like a mailing list I’d be using that instead.
