Starting index at zero












4












$begingroup$


In order to start an index at zero, I found N. Abbasi is quite convenient. For instance,



enter image description here



(Note that in the original code by Abbasi, one of under scores _ in Notation was missing.)



However, with this method, we need to define these notations for each symbol.
I'd like to use any symbols with subscripts, like "a" in the above pic. with the same definition.



Any help is appreciated! Thanks in advance.

          There's no need to use the Notation package to achieve the same behavior. For example:



          SetAttributes[Subscript, HoldFirst];
          
Subscript[a_, i_Integer?NonNegative] := a[[i+1]]


          Then:



          a = {"Alice", "Bob"};
          
Subscript[a, 0]
          
Subscript[a, 1]



          "Alice"



          "Bob"

          ASUS Zenbook UX433/UX333 — Configure Touchpad-embedded numpad on Linux

          Image
          0 1 I have an ASUS Zenbook UX433,on which ASUS decided to innovate by embedding a Numpad inside the touchpad (see picture 1). Toggling between classic touchpad mode and numpad (also turns the touchpad LEDs on) can be done through the golden button in the top-right corner of the touchpad. However, on my Manjaro arch Linux config, this behavior does not work by default and I can only use the touchpad, no numpad. Has anyone been able to configure the numpad to work on Linux, or have any idea how this could be achieved? EDIT1: I have had a look at the official Windows drivers for the UX433FA TouchPad, but was not able to make anything of it. I tried installing them on Linux using tools like NDISWrapper, but they do not detect the TouchPad/Numpad hardware, and my understanding of drivers is too limited.
