NumPy is heavily influenced by APL, as are the math parts of Ada, Common LISP, FORTRAN 90 and beyond, and all functional programming languages. > Therefore, J, APL'S successor in ASCII, makes sense in this regard. > > J has a small footprint and is brilliantly programmed by Roger Hui et al. I have a copy of their published source code from several versions back. It is amazing how Roger used the C preprocessor so that he could write much of J in APL style, essentially giving an object definition for nested arrays containing data of any mixture of types. > Further, Ken Iverson was a teacher until his last breath*. With constant insistence that the right way to learn is by exploration. Try to invent tests that tell you what a function is and does before you read the definition. > The J IDE makes a great environment for teacher and student experimentation. +1 from me, of course. The big question is whether Eric and Roger would be willing to GPL some version of J. The computational core would do nicely for many purposes, although I would far rather have the complete system, including object-oriented programming, graphics, and GUI development. Both Alan Graham and Arthur Whitney are working on enhanced APLs under a Free license, and have offered them for the XO. > Regards, Gerry (Lowry) > > Best wishes to all for a healthy, happy, and safe holiday season. > > > References: > > http://sugarlabs.org/go/Creating_textbooks > > http://en.wikipedia.org/wiki/OLPC_XO-1 > > * http://objectmix.com/apl/152815-ken-iverson-dead-83-a.html > > __________________________________________________________________________ > Gerry Lowry, Principal > Ability Business Computer Services ~~ Because it's your Business, our > Experience Counts! > 68 John W.
