It's not just electricity - just getting a ring caught on something and it's quite painful
My mother was in the WAAF during the war, some of the time she was servicing airplanes. Lots of stories to tell - the technicians were "encouraged" to go up in the plane on the first flight after servicing. Winding up the undercarriage on an Avro Anson. Pilots showing off with aerobatics and trying to impress the attractive young woman sitting next to them. But what sticks in the mind most is the scar from a ring that got caught on the fuselage as she got out.
I can still remember, in the early 80's DEC VAX field service engineers removing their wedding ring before working anywhere near the computer's backplane. Apparently the current available from the power supply could heat the ring to red heat in only a short contact.
And I can still remember FIELD / SERVICE and SYSTEST / UETP too. The good old days of insecurity.
I once had an email blocked by one university because it referenced The University of Sussex (or was it Essex?)
I thought the max size of an SPF record was 255 characters / 512 bytes?
Sort of. Note that there are multiple double quote delimited strings in their record.
"TXT records containing multiple strings are useful in constructing records that would exceed the 255-octet maximum length of a character-string within a single TXT record."
OPM have one of the most ridiculous SPF records I've ever seen.

Not North, the book you refer to wasn't published until 1996, twenty years after my schooldays, by which time I'd moved on to other interests, but your post triggered a memory of Alexander Thom. Another part of the "research" we did at school was investigating the precision with which students could pace out a "Megalithic yard".
I do have a copy of Euan MacKie's "The Megalith Builders".
Trekking poles are invaluable for crossing streams in spate, even if they spend the rest of the time strapped to your rucksack.
Also, +1 for Paramo, but even a Paramo "waterproof" jacket and Berghaus overtrousers won't stop you getting soaked to the skin in the worst weather (been there, done that).
Layer up, with a synthetic wicking layer against the skin.
Taking it to the extreme, don't bother with a waterproof top, instead wear a Paramo/Buffalo/Montane smock.
Jackets come in two lengths. The shorter ones may be more fashionable and better when belaying a climber, but they can leave an exposed gap around your midriff above your overtrousers. Paramo do both lengths, I have one of each. I found my short padded Paramo top in a charity shop in Kendal with £5 on the ticket. I gave them a lot more than that for it.
Back in the 70's, when my brother, sister and I were at school in Keswick, we did a project on Castlerigg Stone Circle and "leylines".
The local education authority provided the school with an HP 9830A calculator/ BASIC computer.
The physics master lent us an ex-Canadian Army gunsight - a compact theodolite. We surveyed all the stones, I did the 3D trig to calculate where on the slope of Blencathra the sun would rise on midsummer morning and stayed up overnight to catch it. Helpful teachers and students with driving licenses drove us to other stone circles. My brother wrote a program for the HP 9830A to calculate the "leylines" between them, then created random points and ran the program again to see whether we got a similar result.
We entered the project into two competitions, one run by Computer Weekly and the BBC's "Young Scientists of the Year".
We came second in the CW competition and were donated an ICT (the forerunner of ICL) 1902 computer, and reached the finals of YSotY.
More details at my brother's website.
For my personal, self hosted web site I used to use Blosxom, but it's getting old in the tooth. I recently moved to Nikola, available as a package in Gentoo. It's a Python program that takes as input plain text files with some HTML markup and turns them into more featured HTML. Fortunately importing my old site was pretty easy using the RSS support in Blosxom.
Girl without smartphone unable to join in lesson
A mum has said her 11-year-old daughter returned home from school in tears because she did not have a smartphone to use in class.
Celeste Lewis said she felt guilty after her daughter Ava's school, Whitchurch High in Cardiff, encouraged pupils to use their phones in lessons to do things like look up locations on Google Earth.
Taking a company's source code and preparing it for release to the wild is not a simple process. I've been there, done that for OpenSTA
back in 2001.
IIRC, it involved checking the copyright of everything, removing author's names (some no longer worked for Cyrano, we didn't want people being bothered by support requests) and not least, removing any jokes or bad language from the comments.
It seems to have been like this for a while. discussion at GitHub Community

Critical systems do not fail because a person makes a mistake, but because insufficient controls fail to prevent the mistake. Dr. Johannes Ullrich
Fission is easier, but that doesnt make it better. Burning Coal is even easier and cheaper
Have a read of this article by Otto Frisch On the Feasibility of Coal-Driven Power Stations
The recent discovery of coal (black, fossilized plant remains) in a number of places offers an interesting alternative to the production of power from fission. Some of the places where coal has been found show indeed signs of previous exploitation by prehistoric men, who, however, probably used it for jewels and to blacken their faces at religious ceremonies.
The power potentials depend on the fact that coal can be readily oxidized, with the production of a high temperature and energy of about 0.0000001 megawatt days per gram. That is, of course, very little, but large amounts of coal (perhaps millions of tons) appear to be available.
The chief advantage is that the critical amount is very much smaller for coal than for any fissile material. Fission plants become, as is well known, uneconomical below 50 megawatts, and a coal-driven plant may be competitive for small communities (such as small islands) with small power requirements.

How Many Years Away is Fusion Energy? A Review
Historically, it has been a running quip that ‘fusion is always 30 years away. ... Thus arises the following question: is the age-long sarcasm of “fusion is always 30 years away” still valid in 2023? This paper answers this question through a literature review of researchers' expectations about when fusion energy will be “ready” for over the past 40 years.
Only 5 or 6km from Torpenhow is Aspatria, which has its own problem. The locals pronounce it "Spyat-ree", posh folk "As-spay-tria", but the recoded message on Northern Rail trains says "As-spat-ria".
