There’s a standard for paper sizes called the ISO 216 international standard, aka A-series paper sizes. You may be familiar with it outside of the American 8.5”x11” letter size. The simplicity, for example, where an A3 sheet is exactly twice the area of A4. One A3 sheet folded in half becomes two A4 sheets. This is intentional: when you fold or divide an A-series sheet exactly in half, the resulting sheets have the s…

I always forget the US doesn't use A4 etc. (or do you?)

Curious to see all the new interaction paradigms people come up with now that we have something physical that can sense degrees of freedom. A dumb one off the top of my head: When reading a book with both screens open, have the outer display show the cover of the book, and closing and opening the screens together causes a page turn. (Unfortunately also a great way to rapidly wear out the hinge mechanism.)

There are some amusing apps which read the MacBook's lid angle sensor. I remember one of them played a creaking noise through the speakers when you open or close it... Somehow I doubt App Store review will let that in for the Duo, but we can always hope.

We keep putting more powerful chips into phones, and giving them bigger screens, but we never turn them into useful computers. Why is this?

Why do they insist on every new phone being bigger than the phones before them? I don't mind folding. I think it's cool, and a nice way to get a useful space. But I have big hands, and I can't use my iphone 17 now without two hands. This is even wider before unfolding. Who wants bigger phones? Who is like, "damn I wish I had a tablet that I could fold up and still barely fit in my pocket"? I want smaller phones. The…

That's why I prefer the flip format, over fold. Typing this on a Flip 3 I've had since 2021, very happy with it.
