My now mantra
is :
WwW is doing what BillGates was never
able to do - - drag me out of CoSy .
I continue to be alone in virtually all business meetings I
attend in actually using my
notebook to take notes . The core of it`s continual utility
is its open linguistic
foundation .

HUEMAN :
For nons , just noet mie eforts toward universal fonetik speling (
tending toward Italian - Eestern Uroepyan noetaeshon ) .
MACHINE : Certain computer languages are
radically more powerful than the common ones used by the masses of
programmers .
I have been living in and co-evolving my CoSy NoteComputer based in one
of these , APL , since 1984 . Some of the algorithms date back to the
mid `70s when I learned A_Programming_Language to help understand the
matrix algebra foundational to my pursuit of an understanding of
psykofiziks .

PERSONAL HISTORY OF APL
Always
Remembering Ken
Iverson , father of APL
| The main English language publication
about APL these days is Vector.org.UK .
I think the best downloadable trial APL is
at : IBM APL2
The best commercial APL is Dyalog
.
A somewhat less expensive APL is
MicroAPL
Arthur Whitney's APL derivatives at Kx.com
are world competitive large scale time series analytical database
systems . It will be a while before I will be migrating my accounting
from K.CoSy
.
SmartArrays by my friend Jim
Brown , who was the chief architect of IBM's APL2 , and James Wheeler
who wrote what is now APL2000 , now
APLnext , I believe will give K a run for the
money in many large scale applications , especially non time-series .
E.g.: : DoD inventory systems .
Ken Iverson's very abstract and
mathematically oriented final notation is J
developed with Roger Hui .

ArthurWhitney `s language : K , which I
consider to be the most conceptually advanced language in its
abstraction of the essential structures of data and algorithms . The
size of his fully working demo executable is just 128KB .
His syntax , tho , has a number of idiosyncracies and , most
egregiously does not allow creation of infix functions . Instead
multiple arguments must be listed in ' [ ; ; ;
] ' list notation .
Thus | ( A f B ) g C h D |
becomes | g[ f[ A ; B ] ; h[ C ; D ] ]
| ( corrected 20070604 . was : |
g [ f [ A ; B ] ; h [ C ; D ] ] | )
.

k is faster (sum of times)

k is shorter (lines of code)
k(9) awk(66) perl(96) tcl(105) scheme(170) vb(200) java(350)
we really are different ...
the benchmark is loops, text-processing and stdio.
we do vectors, data-processing and mmap.

\COSY\COSY!/Job/ArthurWhitney`s:K An e-mail I picked up
from comp.lang.apl archives .
( 960722 | Incidentally , I stayed in NYC THU.JUN,960620 to see Arthur
give a demo of K at UBS . In a demonstration of disorganization
unconscionable for a bank with global pretensions , the projector for
the Sun hi-res monitor could not be found . Perhaps 2 out of the much -
beyond - the - ordinary SigAPL crowd could see any of Arthur`s actual
conversation with his machine . It makes it not worth my uploading my
notes .
To understand the value of this region of ComputerLinguistic space ,
note that UBS is the only user of ( and , in fact , thru `97 06 , has
proprietary control of ) " K " . Apparently 4 individuals , most or all
ex- MorganStanley , support K full time .
Conclusion : UBS spends around %2 M $ on the language each year . )

( Thanks to Carl Distefano , XyWriter . )
The algorithm , while much more illuminating than "Hello World" , is
still far too simple to differentiate deeper structural aspects of the
languages ( altho many of the examples display the overhead required
for those structures ) .
Many other examples , perhaps out of boredom , elaborate or obfuscate
the basic problem rendering them incommensurable . The APL2 example ,
for example , essentially creates all verses in parallel , and thus is
a good example of APL's intrinsic parallelism , but is not the
sequential algo intended .
The K example is such a fugue I think it must have been written by
Steve Apter .
