There’s an old story about that. Possibly apocryphal, but here goes:
IBM mainframes used to come with documentation in ring binders. Some pages might indeed be marked “This page intentionally blank”. And they would from time to time send out update packages to their customers, with instructions to replace pages so-and-so with the included replacements. On the replacement pages, text that had been altered would be marked with a change bar in the margin.
Lo and behold, one day an update package was received, replacing one completely blank page with one bearing the text “This page intentionally blank”. Complete with a change bar in the margin.
You can't know. However, it is a consequence of the axiom of choice (AC). You can't know if AC is true either; but mathematics without it is really really hard, so it usually assumed.
Heh. To borrow an idea from xkcd (measuring gas consumption as area): The kWh measures energy, right? And energy is force times distance. So energy divided by distance is force!
Let’s all start measuring EV consumption in newtons, folks.
It even makes intuitive sense: It correlates well with how hard you need to push the car to get it going at the usual travel speed. But it sucks if you need to figure out how far you can travel on a given charge.
Even worse with just two digits for the year! 01/02/03 could be 1 Feb 2003, or 2 Jan 2003, or 3 Feb 2001. Let’s just be thankful no one ever uses any of remaining three permutations.
This. At highway speeds, air resistance dominates the energy consumption. It is roughly proportional to air density, which in turn is inversely proportional to temperature. Compare a nice summer day at 300 K, say, to a really cold day at 240 K. That’s a ratio of 5:4, pretty close to the 20% figure mentioned.
The interior of Finnmark in northern Norway can get very cold indeed. Temperatures approaching -40 degrees are not unheard of there. The coast is much warmer most of the time as you say.
Huh. I owned a Citroen Ami back in the seventies. It was a gas car (two cylinder air cooled engine), much like the 2CV but made to look a bit more like a conventional car. Interesting that they decided to reuse the name.
Swiping on the search field works (I had already forgotten that), but when you have a lot of pages, as I do, the feedback is much worse, as it does not expand the field to accomodate all the dots. It’s amazing what difference such small details make.
Edit: The feedback is unimportant if all you want is to swipe to one end, if course; which is what prompted this subthread.
> Doesn’t help if you have pages of apps and have to swipe five or six times to get to the App Library
There’s another hidden feature: swiping on the row of dots near the bottom of the screen lets you scroll through the pages at speed.
Om iOS 16, you have to turn off the search field on the home page, since it replaces the dots. Fortunately, you can still swipe down to reveal the old search field.
I wonder if the Air gets the chips with one faulty GPU core? They could just disable the faulty one and use the remaining seven. </idle-speculation>
Edit: Whoops, I see I was not alone thinking that thought.
The barcode on paperbacks is usually UPC, not ISBN (unless it has changed in recent years). And therein lies a big problem: UPCs get recycled. I was bitten by this when I scanned a bunch of old Sci-Fi books, only to discover that totally different titles got assigned to those UPCs later.
