The tables maybe the same quality and much cheaper but on the eve of leaving the EU we should be buying British to secure jobs and. G D P .

As a staunch Remainer, I agree totally Trish. Keep snooker balls British! That's what I say. Otherwise, next thing you know is we'll be seeing a Chinese snooker player knocking the Great Ronnie O'Sullivan out of the world championships!

  Gd_pst                  I'll take that as a YES then, wve

I bet also that Siasl never poo'ed himself in morbid fear every time a mother-of-pearl cloud drifted by.

Ant, I know this article was in the Daily Mail but, but, but...It is a load of airy fairy cobblers! Mother-of-pearl skies are not rare!
I used to see them routinely many times in winters in Norway and I used to live about a 20 minute walk from where Munch lived and worked - so we shared exactly the same skies.
I promise you Ant, and everybody else, that I was never, not once, scared by a mother-of-pearl sky. Quite the reverse in fact. I was entranced by their serene beauty, yes. I was impressed at God showing off his catalogue of visual effects, yes.
But mother-of-pearl skies were not manic or deranged.
Little old ladies and people of a nervous disposition just looked up at them and smiled. Even little Norske kids were totally blasť about them.
Mother of pearl skies are simply paler, static versions of the Northern Lights and just as breathtakingly beautiful. I suppose Munch was terrified of the Northern Lights too? Knickers to that.
It seems to me that the art researchers behind the Daily Mail article are either sadly misguided folk - or they are desperately bending very common atmospheric effects in a frantic effort to make them fit in with their own flimsy art theories until they get something worth publishing so they can get their 15 minutes of fame.
It is true that, as the sun sets in Norwegian winter, the mother-of-pearl skies do get a nice shiny pinky-red tinge - but nothing to scare even the most highly-strung demented art researcher.
Edvard Munch was a painter for gawd's sake!
And as such he always used artistic licence to create exactly the precise moods he wanted to convey - fear in the case of the Screamer on the bridge.
Can you imagine how much less powerful the Scream painting would be with a nice clear summer blue sky background? No. It wouldn't work, would it? So it's no wonder Munch decided to add such dramatic swirling bilious art nouveau clouds.
I suppose next the art theorists will move on to high-falutingly deciphering Van Gogh's tormented whirlpool skies?

Technology / Re: Why is it so slow to 'rewind' on Netflix?

It may well depend on your Brisbane bandwidth, but what is trying to do is fetch a still image from a video stream as you search. Video codecs are complicated beasts and this information will not all be available at one point in time in the video, so it has to download more than one frame of footage.

Technology / Re: How much horsepower can a horse actually generate?
« Last post by P-Kasso2 on 24 April, 2017, 02:38:36 PM »
The horsepower was defined by one James Watt, as being 1 hp(I) = 745.699872 W

He was trying to sell steam engines to mine owners who were used to small horses and pit ponies, and it was to his advantage to make it sound like his engines could do lots of work, so he deliberately chose small horses.  Hence one horsepower is actually a bit less than the power developed by a average horse.

There is also the "brake horsepower".  This was originally an American way of measuring engine power, and conveniently ignores drivetrain losses i.e. it's measured at the engine flywheel and usually a few percent higher than if measured at the driving wheels.

So, Anon, one horsepower is actually one extremely small and weedy horse plodding along! What a shyster that James Watt was! But it obviously worked though.

And thank you too for the explanation of brake horsepower.Unfortunately I am notoriously famous for being about the most un-technical person you could meet. Spanners I have heard of. Screwdrivers I have even used once or twice. And I have actually once seen what I think was a flywheel - but the rest of your explanation is sadly a perfect blur to me.

Technology / Why is it so slow to 'rewind' on Netflix?

I use a host of devices to access Netflix, and whilst it is great for most things, fast forwarding and rewinding are a bit pants all round.  Why is this?
