The new round PN532 NFC readers work nicely, first time. All that work working out exact track length on the square ones and making a spiral track the same length - paid off. Yay!

I am liking the new Environmental Monitors. I just have to finish the UI with the buttons now.

"Never drink whisky that is aged less than yourself", is an expensive hobby :-)

They (HMRC) don’t say what to do if it is a perfectly normal (ie not “unusual”) network set up that assigns public IPs, especially as addresses. Hmmm.

Pissed that UK ICO think an organisation is not required to correct the email address they have record for me!

Door controller looks good with the EL560. Ideal for a domestic installation.

@cadxdr @revk What we think of a NAT today is actually NAPT: Network Address and Port Translation.

1) There are only 65K ports. If you have enough devices to chew through all of these, you need another IPv4 address, which are scarce.

2) Only TCP and UDP have these port numbers. You've now ossified the stack to only these two. Anybody remember SCTP?

3) The client/server model is now fully entrenched. Goodbye end-to-end principle. eg: If I have a RasPi on my network and I want to talk to the RasPi on your network, you now require a middleman that has a public IPv4 address that both devices have to call out to. Did I mention those are scarce?

Every "solution" people throw out there merely delays the inevitable, and usually by a pitiful amount. There are discussions about freeing up 0/8, 127/8, and some of the multicast block. This would extend the pool by, at best, months.

All of this time, effort, and money could be better spent getting #IPv6 fully tested and deployed.
