What's really interesting about @sys is that it supports a search-path at run-time, so the resolution can walk back through a list of target systems to find an available one.

Very much a misconception; unlike in an ICE, you're not consuming energy idling in traffic, in fact your efficiency tends to go up with the lower speeds in traffic.

Thanks for taking the time to do such a thorough writeup on this - it's fascinating to compare with the install we did a couple of months ago on our house in the UK.

We already installed a Daikin Altherma 3 air-to-water heat pump three years ago, which heats around a thousand meters of underfloor pipework + domestic hot water cylinder, but recently added a Daikin air-to-air heat pump. This is relatively new to the UK, at least in homes, so there aren't many contractors in the market yet.

Making good afterwards is certainly the challenge - I'm still repairing the plasterboard (drywall) holes, which I needed to make for access into the eaves. (I preferred this to having lots of external plastic trunking.)

I'm looking forward to seeing how the air-to-air heat pump helps with our winter humidity.

Thanks, that's really useful. I had always wondered about the possibility of doing something like this with my children's various RF-controlled toys.

Really interesting. What sort of hardware would be needed to use this?

Presumably you're referring to the practice of answering queries for nonexistent records with an A record belonging to an advertisement page? (instead of doing the right thing answering NXDOMAIN, presuming no records of another type also exist for the queried name.)

dnsmasq has a really useful feature for dealing with this: --bogus-nxdomain

It would be really good to see RFC 5233 local-part filtering characters (e.g. '+') being permitted in the validation for email addresses on this list. It's much less of a problem these days, but the number of times a sign up form has flat out refused to accept these as valid - or worse the sign up process accepted it, but the login simply doesn't work!

You need to install linux-headers-rpi to build wireguard on Raspberry Pi OS - should be good then.

As an update to yesterday: After emailing our local Member of Parliament (Rt Hon Dame Cheryl Gillian), and reaching out to Openreach CEO Clive Selley, we've finally been connected!

A member of the Chief Engineer Technical Escalation Team was put on the case, who arranged for a Senior Engineer to visit us today. The engineer arrived early this morning, and immediately set about finishing the copper run from several poles away to us. Before long he was back at our door to handle the internal wiring, which he quickly noted had an unnecessary route bridge (I don't know what this means, but it relates to internal copper wiring), which was degrading the signal. After the fix, he got us up and running at just under 30Mb/s (7Mb/s upload) - not stellar, but this will do until our longer term plans come to fruition (a joint FTTPoD order with many of our neighbours, using the Government's DCMS Gigabit Voucher Scheme to bring us 900Mb/s full-fibre).

My family and I are extremely grateful to Clive Selley and his team for taking a personal interest in our case, and local MP Cheryl Gillian's staff for playing their part. (sadly there was no response from Sky CEO Jeremy Darroch.)

The engineer who ultimately got us connected today told me he was in the process of studying for a masters in Nuclear Engineering, and I wish him the very best in that endeavour!

Sadly you're right. AAISP is very much worth a look, but they're not cheap. We went with Sky because they're good for the low price point - our longer term play is a joint order with the majority of our street for FTTPoD (Fibre to the Premises on Demand) through Cerberus Networks (which will cost quite a bit more, but take time). (this will eventually get us up to 900Mb/s, and the build will be entirely funded by the Governments DCMS Gigabit rural broadband voucher scheme, and built by Openreach.)

All indications are that Cerberus are extremely technical - the sales guys were able to talk BGP happily (not literally).
