I'd love to see what an LLM chatbot would give as answers to such time-elated questions.

Much like when I asked one about constrained cabin bag sizing, it hallucinated a reasonable sounding result that was completely wrong and would have cost me money.

I expect the Ministry of Apologetics and Ministry of Vague Explanations will be very busy in future when people mistake it for viable technology.

That's, um, "insufficiently proactive"

It is not a rare problem & is solved multiple times a year by real people.
The obvious answer is to use UTC, but for ordinary folk as distinct from computers, hams, comms people & the military, it is normally solved by knowing about time zones & the iniquitous practice of Daylight Saving.

I don't normally reply to myself, but I was thinking------ ( I know, it's dangerous! ) .

In the example, "next week" is a fairly broad time interval. If he is "currently in Perth" he could drive back to Eucla, using up the remaining one day of EADT, & most of the next day, then everything would be back to normal.
In the real world, his ISP would probably have assumed he was on WAST all the time, anyway, so in Perth or Eucla would assume the same time.
Indeed an error, but a workable one.

An interesting example is buying on line from Coles (for non-Oz folk, a major shopping group).

On their website,on the page showing delivery times, they warn that after 9pm you can't book deliveries for the next day & will have to do it for the day after that.
So far, everything on the website gives the impression of having made the time zone correction for wherever you are in "this wide brown land", but when at 6:05 pm WAST I tardily selected the delivery time for "tomorrow", I realised that their "tomorrow" was my "day after tomorrow", as it was now 9:05pm EADT!

Now this is an excellent post because it shows exactly what the humans who deal with it think about the problem and that is always disparate to the logic applied from afar.

Our approach to solving this was to send someone from the UK who knows nothing about it and assumes that we are the centre of the temporal universe (well we are) to Sydney for 2 weeks and work it out with two people there who have never left Sydney.

You can imagine how that went.

They probably have left Sydney but the concept of time zones didn't "stick"----it's a Sydney thing!
That's one situation where the much-maligned hams have an advantage, as they learn about time zones as part of their hobby.

Indeed.

Possible positive outcome: companies learn not to attempt to blame the victim for the company's crap technology.

Possible negative outcome: companies design mechanisms so they can (more or less plausibly) shift the blame onto victims[1].

That was flying a kite. I can't see why it should be any different to any other company endorsed source of information. And as for checking what it said against other parts of the website.........

There used to be a general store like that in my village; not electronics, just hardware and anything else that caught the brothers' eyes.

Simple example: I wanted a chuck key for a not-very-old Black and Decker drill, so I went to the local Big Shed. They had one, which didn't fit. Go to the local shop, one of the brothers says he thinks they have some, clambers over the floor, then uses a step ladder to reach a shoe box. Has 6 different types.

Unfortunately they died, the shop and their house behind was torn down because it was unsafe.

I remember back when I was in my late teens we used to have an old car showroom that was being used as a Army and Navy surplus store and they had all kinds of odd ball stuff in there ranging from spanners etc right the way through ex military radios etc. That place was always heaving with buyers and rapidly became a regular haunt for me, you would never know just what they get in from one day to the next. Sadly those places don't seem to exist anymore.

An excellent video. Subtitles required and yes it is actually worth sitting through the whole thing which is a rarity.

In Perth, right in the city, we had "Anderson's Salvage", with a very large shop, full of weird stuff like throttle levers for various multi engine aircraft, Avro Anson engines, 800 Hz power transformers, Hupmobile headlights, Edison Splitdorf aircraft sparkplugs, & multiple other less identifiable objects.

They also had a smaller shop,crammed full of surplus electronics, where I used to go to drool at No. 19 & 22 transceivers, but couldn't afford them, so ended up with a No. 11.
That was a mistake, as they were designed for battery use & had directly heated filament tubes.
Easy enough these days to provide clean low voltage DC, but a nightmare back then.

There was another largish place, "O W Strang Surplus" in Victoria Park, just outside the CBD, which had an eclectic mix of surplus stuff, including a Rolls- Royce Merlin engine occupying pride of place in the window.

There were several smaller shops, with mainly surplus electronics.

Over time, the big places disappeared, & the small ones morphed into hangouts for those who liked to wear army surplus clothes & collect, (often fake) militaria, with a sideline of camping gear.

That was back in the day when people did real things in the central city-----now it's just "big glass boxes" full of "suits".
They appear in the morning, disappear into the glass boxes, come out for a while midday, then back inside again till home time.
A flurry of activity, then all is quiet.

I think they screwed up the punctuation.
"Dell Technologies takes the privacy and confidentiality of your information seriously" should read
"Dell Technologies takes the privacy and confidentiality of your information. Seriously".

I presume you are going to ask them to pay for a year's credit report monitoring.

What's the alternative? All companies have layers upon layers of unknown/unknowable crap sucked into frameworks and mixed with libraries. Then one malefactor manages to redirect one component's update to a server in Waziristan/Illyria/NKorea, and the relevant maintainer in Nebraska is on holiday for the next month.

Whimpers, not bangs.

The apologetics department will be out in force. Not much I can do. I very much doubt it'll translate into a real issue for me but I will never buy another Dell product again.

As for cloudy, it's not here. I have the Z50 waiting patiently with a 28mm f/2.8 lens for the photo opportunities. Hopefully London ambient light won't kill it.

Somewhere I have an 8" floppy containing illegally exported munitions. Naturally I need a drive for that; no idea whether either bit of hardware works

Move over obfuscated C, there's competition in town.

This is a proof by construction that the Intel MMU's fault handling mechanism is Turing complete. We have constructed an assembler that translates 'Move, Branch if Zero, Decrement' instructions to C source that sets up various processor control tables. After this code has executed, the CPU computes by attempting to fault without ever executing a single instruction.
