RE: Helping the 50g, Prime or Nspire?
I did not realize that the ti nspire was so big. It is massive.

Next step will be the real prime / nspire CX (I'm not sure if it makes sense to buy the Casio families, they seem great but they have always very little ram, less than the 50g/ti89)

The 50g is already big, the nspire is bigger.


update 201706. So I tried the nspuire with lua (to cover the missing parts of newRPL until it is in development) and while the execution of lua on a basic nspire (the first type) is very fast, the utility of the result is abysmal. The lua interface on the nspire is drawing oriented so at the end it is very difficult to manipulate the results. Either one does everything in one go in lua using the math server, or the opportunity cost to program in lua, debug the problems and then handle the result rather than using ti basic (that is still super simple and is 100 times slower than lua, if there is no "server.math" involved, but in absolute terms it is still fast) is not enough.

Really one wants to squeeze the calculators but there is a limit to clumsy setups, otherwise one ends using a computer or a raspi.

So the nspire seems still usable, but one has to use mostly ti basic (also, can be shared with the ti89) , lua is too demanding on the programmer side. Not that it is a difficult language, it is just difficult to handle results that are images for the calculator.

in general the ti basic for the nspire is very tight related to the nspire student software that is given with the calculator itself or can be bought with a subscription but it is valid for one hard drive, so a bit dismal. It means one has to pay a lot or continously TI to get programming abilities on the PC.

The nspire itself could be a nice calculator but without the possibility to develop on the pc with good debug, it is not usable for large tasks.

Update: as discovered Ti basic for the nspire seems usable only on the device if one has no "ti nspire student software" that requires a constant subscription.
This is even more clumsy than lua.

Instead lua, although made for graphics, can export values. See https://inspired-lua.org/index.php/2011/...ssibility/

That then have to be saved in the document as "calculator page" to be mangled. Still clumsy, because based on the device unless one does everything in lua, but better than the situation thought before.

Wikis are great, Contribute :)
