"Out of the mouths of babes and sucklings…" [Psalms 8:2] I congratulate Jane in presenting us with the heart of a precious FAQ list which ought to figure prominently in Jwiki (…but doesn't *). Ditto prominently displayed in Wikipedia (…but isn't). Brief but authoritative answers to Jane's Seven Questions would not only dispel the fog of many introductions to APL and J (…most of the many??), but cut straight to the bone of both languages. I personally can't do justice to Jane's questions without writing a book – and it will be a most interesting book to write. And maybe to read. ** But both APL and J are notorious for their one-liners. I challenge the community to furnish one-line answers to Jane's seven questions –J7Q (you're allowed a modest-length comment). I have mine ready to-go, but I want to see someone else's first. Footnotes (*) – searching Jwiki on "FAQ" gets you: http://code.jsoftware.com/wiki/Guides/General_FAQ http://code.jsoftware.com/wiki/Guides/Language_FAQ …Both are stubs. It seems to me J's Frequently Asked Questions are not Asked Anywhere Near Frequently Enough !:/! (**) – Hats Off to Bob Bernecky for a superb impromptu paper on the industrial archaeology of the APLs (Array-Processing Languages) One gets the feeling he might have heard it all before :-) On Thu, May 17, 2018 at 10:02 PM, Roger Hui <[email protected]> wrote: > I remember the paper well: The Prime Factorization of 1, by Jeffrey > Shallit, now professor of mathematics at the University of Waterloo. n = > */ q: n, therefore: > > */ q: 1 > 1 > q: 1 > > (i.0) -: q: 1 > 1 > > > > On Thu, May 17, 2018 at 1:56 PM, Nollaig MacKenzie < > [email protected]> wrote: > > > > > On 2018.05.17 13:14:26, you, > > the extraordinary Roger Hui, spake thus: > > > > <...> > > > > > > One way to think about index origin, is to consider the question > whether > > 1 > > > is a prime. http://www.jsoftware.com/papers/APLDesignExercises1.htm#14 > > > > > > > Aeons ago, in _Quote Quad_, there was a paper, "The Prime Factors of 1". > > Answer: i.0 > > > > > > -- > > Nollaig MacKenzie > > ftp://ftp.nollaig.ca/pub/pap/ > > pgp key C6E9845A > > ---------------------------------------------------------------------- > > For information about J forums see http://www.jsoftware.com/forums.htm > > > ---------------------------------------------------------------------- > For information about J forums see http://www.jsoftware.com/forums.htm > ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
