Thanks for the information about this American business phrase. The implication on an invitation is that who invites is trying to sell you something (there is no free lunch in business).
I would find interesting something related. Creating a platform for defining the next stage of an idea and how to code it in software. A collaborative remote project.
Maxima provides: Symbolic computation, blas and laplack integration for numeric algebra, 500 pages manual in several languages, a complete library for statistics, differential equation, calculus, series. Graphics with matplotllib. Also maxima language is not much complicate that python:
for i in range(10):print ii versus
for i:0 thru 9 do print ii;
[i2 for i in range(10)] versus makelist(i*2,i,0,9)
But Matlab libraries are greater than python and maxima.
