Happy to report have drilled holes in one wall, one ceiling and one floorboard, fed some cat5e cables through them and successfully crimped four terminators (20 years ago I knew how to make ethernet cables ...) I now have wired ethernet in my study and the difference between wired networking and powerline ethernet is the difference between 10Mb/s and 70Mb/s according to fast.com

A happy side effect for any local radio amateurs/CB users is that my mains wiring is not longer a giant radio aerial https://www.ban-plt.org.uk/

I wanted to relocate my router/wireless AP from the dining room into the living room, because (1) that's where most of the clients are most of the time; (2) makes it easy to run an ethernet cable to the TV area for the Kodi box; (3) eventually I will drop another cable from the floor above so I can have ethernet in the third bedroom (aka study) too. It could have gone simpler, especially the part where my drill bit was too short, the part where the longer drill bit I bought turned out to be very nearly too short too, and the part where it turns out I have no portable devices that have an ethernet socket, making it rather more complicated than it need be to test the cable before plugging the router into it.

Somewhere around the place I have the ethernet adapter for this thinkpad. Can I find it? Hell no.

This is a minimal circuit to get an ATMega328 running solo, without the Arduino board and USB stuff

If you leave out the 16MHz crystal and use the onboard 8MHz clock, you can bring down the power consumption even more, but at lower speed, obviously

The thing to keep in mind that the Arduino pins and the ATMega chip pins aren't the same. There's some mapping translation involved if you're using the Arduino IDE to program one

Turns out the reason I can't ssh into my new VPS from the office is not any of {"because it's down", "because it's firewalled", "because there are weird DNS problems"} but "because I was spelling the hostname wrong".

There is some level of irony here: https://mastodon.social/@telent/100013088526728986

"Most Linux systems" seems like quite s strong claim: the vast majority don't even run pppd, and of those that do, surely they run it only on the network interface corresponding to their uplink port? Are there use cases for running pppd on an Internet-accesible interface?

If you can see this, I moved hosting for terse.telent.net from Bytemark to Mythic Beasts. This is the first of several services that need migrating from my old VM to my new one.

(The zeroth was DNS: now instead of using Bytemark's content dns I am running an actual DNS server with actual zone files, and I cannot tell you how much more pleasant it is for setting up AAAA records than futzing with tinydns format files was)
