Peter once told me that in 1973, the only two organizations permitted to do telecommunications were the Post Office and the Ministry of Defense. So to legally connect UCL to the ARPAnet, he needed an exception clause. Somehow he got both the Post Office and the Ministry of Defense to sign off that they were not interested in computer-to-computer communications, in perpetuity, so that UCL could do so instead. He said he never tried to hold them to it later.

I was also in one of those basement labs in the Pearson building in 1988. Not exactly the nicest place to work, but some great equipment. I particularly remember that year coding a graphical application in NeWS (Sun's original network window system, long before it became X/NeWS) on a Sun Workstation there, which was an amazing piece of kit for its time. Also remember the DecStation 3100s we had down there that would periodically catch fire.

UCL was on both the JAnet X.25 network and the Internet when I joined in 1985, and provided a relay service between the two for email and for telnet. Maybe others - not sure. Relaying email required translating the address order as the UK used big-endian "foo@uk.ac.ucl.cs" and the rest of the world used little-endian "foo@cs.ucl.ac.uk". There were a whole set of heuristics to figure out which order the destination should be, which worked fine up until Czechoslovakia joined with their .cs domain. I think it was probably in the early 90s when JAnet fully deployed IP-over-X.25, and all UK universities became IP-reachable, but some would have been reachable before then.

Peter was also responsible for the UK using .uk instead of the ISO country code "gb" which it should have been according to "the rules". But Peter insisted on .uk, as the official name of the country was "The United Kingdom of Great Britain and Northern Ireland", and he thought GB was not properly inclusive of Northern Ireland. It took until 2021 for UK to replace GB on car number plates (and stickers for travelling abroad).


There was an FTP relay as well.

I worked for Peter Kirstein for many years - he always had wonderful stories to tell.

In the article Peter talks about the temporary import license for the original ARPAnet equipment. The delayed VAT and duty bill for this gear prevented anyone else taking over the UK internet in the early days because the bill would have then become due. But he didn't mention that eventually if the original ARPAnet equipment was ever scrapped, the bill would also become due.

When I was first at UCL in the mid 1980s until well into the 90s, all that equipment was stored disused in the mens toilets in the basement. Eventually Peter decided someone had to do something about it, but he couldn't afford the budget to ship all this gear back to the US. Peter always seemed to delight in finding loopholes, so he pulled some strings. Peter was always very well connected - UCL even ran the .int and nato.int domains for a long time. So, at some point someone from UCL drove a truck full of obsolete ARPAnet gear to some American Air Force base in East Anglia that was technically US territory. Someone from the US air force gave them a receipt, and the gear was officially exported. And there it was left, in the US Air Force garbage. Shame it didn't end up in a museum, but that would have required paying the VAT bill.


If only it could have disappeared into a vault until now... the bill could have been inflated away!

I'm British, but had never heard of it until I spent New Year with my wife's family in Denmark a few years ago. Indeed it does seem to be compulsory viewing there, and no-one could believe I didn't know it.

How does that work for identical twins?

The same way as it does now. The face is checked against the identity claim, not against the global lookup, which can't reliably work anyway.

So there's no non-repudiation making it no different than a paper document.

Sorry I can’t really parse the comment, but I do agree it’s no different from a paper document, because why would it?

It's hard to think of any scheme that fully works for that, unless you mandate distinctive body modification like tattoos or scars.

The Polestar 2 is pretty good in this regard. All the most important things are on the steering wheel stalks, steering wheel buttons, and a few buttons for things like demist, play/pause and volume control on the centre console. There's still a lot on the touchscreen, including climate control, but it seems to hit a pretty good balance for me (and I'm not a fan on car touchscreens).

I love my Polestar 2. But there's gotta be a better way to do touchscreen climate controls. I've had mine for 8 months now, and had to google in order to figure out that the car had dual-climate zones—it's really hard to tell from the swipe-up page, so I just assumed it didn't have that feature for a while. Plus, I don't feel comfortable changing the climate settings while driving, because I might hit the wrong touchscreen button when I'm not looking at the screen.

But hey, maybe if I wait around another 5-10 years, there'll be more than 3 mainstream electric sedan options available for the US market and I'll be able to find the perfect car.


Recently drove a Dodge Hornet rental and it had a slew of physical climate buttons, most of which didn’t make sense or didn’t control what I wanted. In the course of trying to just turn on the defrost from the touchscreen, I turned on the heated steering wheel, stopped the airflow to the cabin, adjusted the driver side temperature way higher than I wanted, and probably subscribed to Disney+

Here's a pretty complete list of UK brands: https://moralfibres.co.uk/the-teabags-without-plastic/


Unfortunately the best of them is 1080p.
