We have some sad news about Facebook. It has returned to the internet after six-hour mega outage

"It also confirmed an accidental configuration change ultimately caused the loss in connectivity"
It did no such thing. It just said "configuration changes".
To paraphrase:-
"These aren't accidents, they're throwing themselves into the outage! Throwing themselves into the outage gladly to escape all this hideousness."

You look for the largest objects in the universe and two come along at once: Astroboffins spot mega radio galaxies dwarfing Milky Way
Wednesday 20th January 2021 12:20 GMT 
"A large team of researchers []..] said they managed to find not one but two huge radio galaxies over a small patch of sky. [..] Based on our current knowledge of the density of giant radio galaxies in the sky, the probability of finding two of them in this region is less than 0.0003 per cent."
Maybe there's a black hole or something very massive between us and the giant radio galaxies, and the two galaxies are the same one? Gravitational lensing and all that, like the twin peaks of Mount Kilimanjaro.

Re: Fluorescents...
If you have an old fluorescent fitting, make sure you change the ballast from magnetic (basically an inductor and a bi-metallic strip) to electronic.
https://www.lampshoponline.com/advice/ballasts-explained-the-complete-guide#_Swapping_magnetic_ballasts
There's a myriad benefits. Faster turn on time, even when it's cold. More efficient. Less EMI. No flicker. Longer lamp life. No hum. Etc...
p.s. Disadvantages. "There is a risk of electrocution when changing a ballast so if you’re unsure ask an electrician to do the job for you." :-)
Dratted 'housekeeping', eh? 150k+ records deleted off UK’s Police National Computer database

Re: the loss relates to individuals who were arrested and then released with no further action
Plod has to delete the data after 3 years anyway. What's more, keeping a backup after this time would mean the data wasn't deleted, which would be illegal. To be honest, I'd be more worried if they _were_ able to restore a backup after this cock up...

Re: Sodium Sulfur
Well, vanadium is the 20th most common element in the crust, and you're correct that world production is low. But that's because no-one needs any more than is already produced. For example, chromium is the 21st most common element. World production is 26,000,000 tonnes per annum. So, if demand increased, it wouldn't be hard to produce some more. It turns out that we release about 110,000 tonnes of vanadium into the environment each year through burning fossil fuels, which is more than actual production.

Writing it down on a piece of paper isn't so bad. It's secure from online attacks, especially if you don't reuse passwords. If someone's prepared to break into your office to get the password, they're probably prepared to threaten you with a claw hammer or bribe you to get the password. But just use a password safe. Then you just remember one password. Try this:-
