More and more tasks like big data
handling (eg archived signal analysis) appear even in the embedded
world. Forth has no answer to this. Either some Forther(s) reinvent
Forth, or it will shrink to about non-existance within its niche.
I replied :
CoSy evolves from Arthur Whitney's http://Kx.comK in open Forth . K is one of the most competitive " Big Data " contenders .
While differences in interests , mine : the ultimate ` individual's
Tool of Thought ; Arthur's : the most billions of transactions per
second .
So very different priorities . Most particularly : all indexing in CoSy is modulo , and simply calls the OS allocate and free .
I think performance on a moderate x86 is remarkable anyway .
There is no reason why , optimized for speed , it should not be competitive .

Quote of the Week: “I don't know what's the matter with people: they don't learn by understanding;
they learn by some other way - by rote, or something.
Their knowledge is so fragile!”
Richard Feynman
I like Robert Heinlein's word grok from Strangers in a Strange Land . Merriam-Webster ( who appear to have survived the transition to the Web ) : to understand profoundly and intuitively .
This
is what Feynman was referring to . Serious thought and
understanding requires the precise abstraction of mathematical notation
. Often the learning starts with qualitative familiarity with a
phenomenon . Then one learns and plays with the equations
abstracted thru the centuries of gurus who devoted their lifes to
understanding some bit of reality .
Many seem to simply memorize or learn to compute the equations so they can pass the tests .
A few really internalize the relationships as universal hard won truths about our reality .
The thrust of APLs , evolving from matrix and tensor algebra , has been to make that notation executable by computers .
For instance gravity .
The equation for Newton's Force of Gravity is , in traditional infix notation :
F = G ( m0 * m1 ) * r ^ -2
and the corresponding Energy , Force's integral :
E = -1 * G * ( m0 * m1 ) * r ^ -1
In CoSy Forth's noun noun verb aka: RPN syntax , these ( which apply directly to entire arrays ) currently become
By Conservation of Energy this energy must be accounted for .
This is high school physics stuff . You should have an asterisk on your degree if you do not understand this .
The heat coming in from the Sun equals the heat being radiated to Outer Space .
Slightly more advanced , 2nd year Calculus , is the Divergence Theorem
which demands that the mean temperature inside must equal the mean
temperature outside unless there is an internal source of energy .
Note that gravitational energy above computes as a negative rising to 0 at infinite r . The adiabatic ( constant total energy ) gradient as one descends thru the mass of the atmosphere ( and on into the interior ) of a planet explains why and by how much the bottom of the atmosphere is greater than the 239 watts % meter ^ 2
Hayden cites . The continuous race to reestablish this gradient given
the uneven heating of our rotating sphere drive all weather .
( Actually Feynman was wrong in positing an
iso-thermal atmosphere , I'm sorry he's no longer alive , and I'm sure
he would be to , to debate it . )
The AlGoreWarming ` trapping of this temperature gradient by the atmosphere's spectral filtering is simplyfalse at the lower undergraduate level . Thus there has never been fundamental testable equations explaining and enabling it .
Footage of petty thief
son Asa flipping off new
surveillance camera before
unplugging it .
The horror story of the Satanist Tenants
unfortunately continues and because of my naiveté in filling out court
forms , I may not be able to get them physically removed for 90 days . It's been
astoundingly difficult to get an attorney , but it , and helpful
friends , have certainly taught me to use the phone rather than think
email will get the job done .
I finally have Herman Lohse to make sure everything is served and filed
correctly , and to get advice on what is legally possible and what is
not . The situation is beyond what a lot of lawyers are willing to get
involved with .
The court says that I must allow these criminals access to the
laundry
and bathroom because there is none in their RVs ( only one of which was
ever in any even verbal agreement ) and cabin for which they are paying
nothing . Monday I finally got a surveillance camera to point down the
hallway to have some protection from them coming past the bathroom .
Their son Asa , now 18 , who never went school since they moved here in
2019 and is a petty thief in the habit of leaving pennies to mark his
territory , promptly gave a finger to the camera and unplugged it . I
plugged it back in , of course .
Perhaps the memento I mind most that Asa stole is a thin stainless
steel pocket knife engraved and presented me by the Manhattan
Libertarian Party when I left there for here .
As this Blog and its support in CoSy evolves , it
is taking on a more significant presence . I have now added it to the CoSy front page . If
you are running CoSy, the Job is
downloadable at http://cosy.com/y21/blog.csy
giving you all the tools for searching , extracting , etc that the CoSy vocabulary
provides .
