This is the Rochester LoCo Meeting Event Event for the Ubuntu New York Local Community Team starting at 7:00 PM and finishing at 9:00 PM. Details:70-1400 RIT Campus room: 70-1400 Dr. Peter Anderson, Professor Emeritus RIT, will give a presentation on J. J is Ken Iverson's APL in disguise. Unlike APL, programs are written in ASCII; like APL it is a superb "array processing language" -- Iverson called it an executable mathematical notation. J is a functional language: functions are first class object, easy to define and manipulate. It is interactive, like Python, Perl, etc. J reminds me a lot of the Unix shells with lots of well thought out elementary components and the glue to stick them together (i.e., pipes, redirection, etc.). J supplies the primitives for dealing with arrays (lists, table, report) and the glue, several types of function composition, to make a superbly useful system. See http://jsoftware.com/(approve sites) for a copy of the software as well as lots of free books and articles. All Activity Pages have been copied and adjusted from their original home on the New York State Team Wiki as time permits. Due to format considerations there may be differences between them. |
