Forgot to add: if you enable IPv6, be sure to use the browser extension IPvFoo. It shows a small 4 or 6 in your URI bar to let you know what protocol you're connecting to. Once enabled, you'll see just how much stuff out there actually is IPv6.

Started the move about 18 months ago when I decided to get off my lazy ass. My ISP gives out a /56 prefix, so that lets me run 256 /64 subnets/VLANs in the house, currently there are ~10 in use. Everything get a GUA through SLAAC and I use RAs (Router Advertisements) to give ULAs to everything. Any external facing services get their own VLAN and /64 for the system(s) as needed. Firewall blocks all incoming as they usually do by default and I punch a hole for the external-facing systems. They can't reach back into the network, they only answer the phone. All the systems update DNS dynamically if the prefix or full address ever change.

I have an SSH bastion set up. In all this time there has not been a single SSH attempt from the internet. On IPv4 it was constant background noice.
For those legacy IPv4-only systems on the internet, I set up NAT64. I have an IoT VLAN and IoT 2.4 GHz wireless network that are only IPv4 because a lot of IoT network stacks are junk.

I'm still farting around with it, but man oh man, there's no way I'd go back to IPv4. It was one of the best moves I've done in ages.

That's the problem. Luls you into a false sense of security, then when you aren't paying attention it fails and you die.

It's easier to capture the emissions of gas electricity plants. Everything else can be electric.

To an extent, but nobody in Europe is building nuclear at a reasonable cost. It's worse here, but once France is forced to replace its reactors, if it goes for more nuclear I expect we will soon find out how little doing lots of them really helps.

Maybe you don't understand what 95% renewables means. It means that over the course of a year, 95% of electrical energy is generated by renewables.

Interconnects allow us to buy renewable energy from other countries.

The UK's current goal is 95% renewables and nuclear over a year, by 2030. What will probably scupper us is Hinkley Point C, the new nuclear plant, being delayed.

The trains are so reliable, not just the bullet trains, that if they are delayed by more than a few minutes they have a bit of paper you can collect and show to your boss so you don't get into trouble.

The bullet trains operate on a 15 second interval timetable, but the drivers typically try to arrive within 1 second of the advertised time. They have a system where they make up time by accelerating a little harder, so they never need to exceed the speed limit. They do the calculations in their head to figure out how to arrive at exactly the right time.

They have been trialling driverless Shinkansen (bullet trains), and one of the parts they had trouble with was replicating that system in software. The new maglev ones are driven by humans, but because the trains are so fast they can't really see things like signals and speed limit signs, so the communication systems with the train have to be extremely reliable. The stopping distance at 500kph is 6.6km, although even the conventional railed ones need 4km.

Even in the conventional Shinkansen, the human drivers are not allowed to do too much themselves. If there is a fault, they are required to open the fault resolution manual, look it up, and follow the instructions precisely, similar to aircraft pilots. There are very few "memory items" that they are supposed to resolve without consulting the book.

The way it is supposed to work is that it allows the site to do a cryptographic challenge and response. The site can't tell which device was used, or even if the same device is used each time. There is not communication with the government after the initial confirmation of ID.

That is assuming that all the crypto works properly, of course. Hopefully they have some experts involved.

I'll still VPN into a country that doesn't have such laws as a matter of course, but given that most people seem to think this is a good thing, and we live in a democracy, it's probably the best possible outcome. The current situation in the UK, for example, where you need to prove your age to each site individually, and they all get your real ID and then abuse it and it gets stolen, is close to the worst.

I think the government did everything they could to make it happen and support EDF/Chinese Nuclear. It's just insanely expensive. Sizewell C is the largest building site in Europe. It's not just reactors, it's fuel storage, waste storage, processing, maintenance, monitoring, emergency systems, all on site.

They even had a head start, since the site already had the grid connection and other infrastructure like roads and security that were needed for the two old nuclear plants.

I'm not exaggerating when I say nuclear is expensive. SMRs won't make it cheaper either, because the reactor is only a small part of the cost.

It only seems absurd because your premise is absurd - a whole country UPS.

In reality there is always a minimal amount of renewables, we have gas backup plants (that's what the 5% is), and we have interconnects to other countries.

I hope it is a decent upgrade, because I have to say that Shinkansen wifi is pretty terrible. It's slow and frequently drops out. It's bad enough that I don't bother with it and use my phone's own cellular connection.

This is actually tech that is built into the seat headrest, and supposed to be able to block sounds from the same room. So presumably it is not trying to quieten the already very quiet trains, but rather the other passengers.

Sizewell C is being built by EDF and China General Nuclear Power Group.

The problem with microwaves is you usually only use them for a few minutes. Ovens go for longer, but I'm not sure how much more power they actually use after the initial heating up stage.

So years ago I was helping out with a project to build an industrial tablet computer. They had picked Windows CE because the app developers were familiar with Windows. It was supposed to support a Microsoft technology called Silverlight, which was similar to Adobe Flash, for making the UI. Problem is, it just didn't work. Microsoft weren't interesting in fixing it either.

So I found Silvermoon, an open source version of Silverlight. It was a bit buggy, but we eventually got it working. While debugging some memory leaks, we found an interesting bit of code.

const int one = 65536;

To avoid using floating point maths, because back then some ARM chips either didn't have FPUs or they were slow, the code used the old trick of multiplying everything by 65536 (2^16) to create what is effectively fixed floating point maths using only integer instructions.

I just found it amusing that they decided to call the variable "one". It's actually a reasonable solution, and it did work.
