Thank you. I didn’t know about QMK. Interesting. But actually it was the OS kernel keyboard driver I meant.

Personally I’d want just to connect two standard keyboards. One for each hand. But then I’d need a keyboard driver that will let the shifting keys on one keyboard affect key actions on the other keyboard. Is it hard to write my own keyboard

I prefer the iOS app called 42s. Better user interface in my opinion.

> A sequence of commands that leaves the stack non-empty? That’s actually a feature. It’s even fundamental in concatenative programming languages such as FORTH and Factor.

And there is actually no such thing as an empty stack on an RPN calculator. A four register stack, as is common, always holds four numbers.

Algorithms for RPN Calculators by John A. Ball (1978) landed in my mailbox two days ago. It’s each and every detail you can imagine regarding RPN. Very well and thoruogh written. A great pleasure to study it: https://www.amazon

I wonder if it’s possible to do this by scripting macOS Preview?

If pages are numbered, the largest page number is still on last page. Just look there. Or alternatively: The first step of your binary search is to look at the page number on the flip side of page 1 and determine to flip the stack or not.

It’s obviously not meant for stapled. For the advantage see point 2. under Why would you want to do this?

I can’t argue with that. That was not my point.

You could interpret the comment as: Students, our future developers and power users, should not be locked up in their perspective, but be set free to choose the best for their future endeavors.

Oh, it did add something for me. It actually triggered som perspective thoughts I otherwise wouldn’t have had.

In my country I think it is so when the agency will need some kind of financial backing from the government.

The publisher is gambling. I don’t know much about non-fiction, but regarding fiction they actually loose on most books and win big on a few. Would you think it’s better if publishers only published if they were really sure it would sell?

I believe the actual nature of dreams are not as we remember them. When we recall a dream and makes it a conscious thing we interpret it as we interpret other recollections by making a coherent story of the basic memory. So I dont’t think w

I use the standard keyboard. Don’t know what I can compare the look of it with. I’ve never seen or used an Android device. Maybe I can find a keyboard app with an Enter key.

How do you press “the Enter key” on an iPad? My operators are just stacked with Return.

The trick can make any square easier. Take 27 * 27, make it 3 up and 3 down, i.e. 30 * 24 = 720. Then adding the 3 squared you get the answer 729.
