Every now and then on BT Sport (though I think other channels) there will be a number put in the corner of the screen for a few minutes.




What is it?

Who do shops insist on putting all their products with the best dates at the back of the display?
Seriously?

Because they want to sell the older stuff before it goes out of date and most* shoppers take from the front.

It's called "stock rotation"

(* - although some are wise to it, as you have observed)

The BBC program from Sainsburys was on the other night, they had some stock removed from the shelves because the date was too far in the future, so that customers would buy the shorter-dated ones in the front of the display. Then the shift changed and someone helpfully came and put the long-dated ones out again, which didn't go down too well.

No they don’t, they use a three code number. Thursday on caulis was 312 and a quick glance at the other stock showed it was the highest number and thus the freshest. This goes up to about 330 and then resets and goes back to 300.
Well I've just looked at something bought from Tesco and in the date box it says 19311, which looks like a Julian date to me.

But let's take that you are right and the date is some number between 300 and 330. What use is that to a member of public? With respect, stuff all use as it's not been communicated.

Then consider that I've found stuff on Tesco shelves not only out of date but rotting, only to get a response that as soon as they started to check things "this section used to be a lot better when I was on it but....rolleyes " Seems like staff don't understand it or don't care.

Equally seen Sainsbury's bringing milk out with later date than that already on sale. Which gets back to the point that obfuscating the date issue by using unexplained codes is only for the benefit of the store and no one else. Nobody seems to be denying that.

It's a unique identifier from your box, so that if you share / stream it, it can be traced back to you.

Sky do the same.

Often done on live sporting events, like Sky F1 or whatever.

Here's one for the physics experts- if I put a given amount of water on the Gas to boil and use the lowest setting, it will boil eventually. If I put it on the highest setting it will boil faster obviously. My question is; have I used more gas on the lower setting?

I would guess yes due to heat loss to the surroundings for a longer period.

It would depend on the size of the pan.
You have to weigh up the losses that are greater over time with the burner low - and the losses from burning so fiercely that the flames shoot out the side of the pan/kettle base, and don't actually heat the pan.
Buy an electric kettle ( and put a smart socket on the wall if you need to time the boiling for your arrival/return biggrin )

Thanks. That's pretty much what I thought.

I'd like to know that too. One of the French car companies had a Diesel Hybrid a few years ago, I'm sure it was 200bhp and offered something really high like 80mpg.

Why did it take 40 years to change from Exx to Fxx BMW model codes, then only 7 years to go from Fxx to Gxx codes?
Have they really produced 5x as many variants to use all the numbers up?

Some sort of lower capacity limit below which diesels aren't efficient, maybe? Heavier than an equivalent petrol engine too.

Works Units Only.

There's many slip roads off motorways - some signposted as above, some not sign posted at all that, looking at maps and applying a little local knowledge, simply take you back onto the opposite carriage way, under the motorway or above it.

Question is, are these illegal for other motorists to use?

I was stuck in a horrendous jam a few months back on the M11 southbound just past J9 and there's a little service road (unsigned - looks like a driveway to a house) that takes you back the other way. I nearly used it but bottled it.

When I was growing up, all the locals round my grandma's way used to come off the motorway at the Services and then go down the service road at the back of the car park that staff / deliveries / etc. used, despite it having a No Entry sign with "Access Only" beneath it, which would take you onto local roads and straight to the village where she lived. It was a really worthwhile shortcut as the next proper junction was miles further on and then you needed to double back by the same distance.

A while back I tried that at my local services, due to a huge traffic jam on the motorway, but these days with CCTV and ANPR and the like, there was a huge sign threatening dire consequences if you did similarly, saying your numberplate would be recorded, and fed through ANPR, and missile-enabled attack drones would be despatched to terminate you with extreme prejudice (ok, I made that bit up) and I likewise bottled it. There may even have been a barrier - I honestly can't remember.

So, the answer is, I don't know. But with CCTV and ANPR fairly cheap and commonplace these days, you are less likely to get away with it than you were in my grandma's day.

Something to do with the fact that if you do that, you haven't exited the motorway properly? I didn't quite understand the rules on that, given that when you enter the services you frequently drive pas the "chopsticks" sign marking the end of motorway regulations anyway.

I was with a group of mates in 2007 when there was widespread flooding and we had been stuck on the M40 for hours with no sign of really getting far. My mate drove half a mile down the hard shoulder to the services, and after lunch he did the "go out the back" route and ended up on some local roads, despite a couple of us suggesting that if the motorway was flooded, what were the local roads going to be like? (they were more flooded than the M40 and we were stuck much, much longer than necessary)

How did them Nazi cyanide suicide capsules work ?

I believe they were a permanent fixture, fitted in a tooth cavity and when you thought your time was up you bit down hard on them
and the angels came.

I'm thinking there must have been a risk of accidental suicide when you fancied a bit of hard toffee or blackpool rock.

I don't think they were 'permanent'.

But they could be smuggled inside the mouth, and if push-came-to-shove, then used to kill yourself to protect the information inside your head.
