  • I don’t agree that you usually would still use NAT with IPv6. I’ve never seen NAT in combination with IPv6 and I’ve seen plenty of deployments at our customers. NAT is not the same as a firewall, so just using public IPv6 addresses does not mean that you are exposing every port by default. I think you should read up on IPv6 and firewalling before making statements like this :)

    Edit: you don’t even have to set up firewalling on each internal device… the router/firewall blocks inbound traffic by default.



  • A fun experiment I did recently was to measure the speed of sound with my oscilloscope. I wired up a speaker and a microphone at a known distance from each other, connected the oscilloscope to both sides and measured how long it took between sound trigger & reception. I came within several meters/second accuracy which I think is a nice result for a basic home lab setup.

    I also track a lot of metrics around the house using Home Assistant. Temperature, humidity, power usage, light levels, heating, but also stuff like total meters of filament used, total objects printed, system metrics. I like statistics and it’s fun to compare months/years and clearly see the results of improved isolation for example.
