CoSy evolves APL in Forth
Forth gets you from the Silicon to the Dictionary
APL > K > CoSy fills the dictionary at the most general level
+ CoSy FACTORS looping . ( Modulo indexing )
`( 'm 'd 'L 'R ./ .\ )` >t0> |
Like the transform between Dirac&Kronecker ` delta and Fourier space .
Between items and objects
convolution vs product
To enable that transformation , Type and Count need to be factored
from the ` verb to the ` noun
`( Type # refCount )`
ec Words ' # 'm ,/
t0 ' :?? 'm
The CoSy vocabulary evolving and building on APL tends to be
geometric and algebraic
eg:
`( # take cut VM MV match con venn )` ' :?? 'm

THE BRILLIANCE OF APOLLO 11
The 1969 Apollo Guidance Computer
https://youtu.be/B1J2RMorJXM
Spent a lot of time digging into Reva Forth exception handling but
don't have it handled yet .
Trivial to write something that blows the system away .
Also the venerable IUP GUI has bugs of its own ( MUST LEARN WEB INTERFACE )
Apollo says , screw it . RESTART at last check point

http://cosy.com/y21/Wed.Mar,20210324.html#4th.CoSy
CoSy's Most Fundamental Use is as a timeStamped Diary.NoteBook.Log
From very early on CoSy has done a ' save before every execution .
0
So it was just a matter of changing the DOS .bat file to loop .
I could have done years ago .
But it makes a radical change

o CoSy is a vocabulary and interface which evolves from http://Kx.com K in open Forth . Thus it provides the expressive power of the former in the simple syntax and unmatched flexibility of the latter in a timestamped notebook/log environment .
o A YouTube , see http://cosy.com/y21/Wed.Mar,20210310.html#4th.CoSy , on the Apollo 11 lunar lander computer & its design principles , particularly the crucial simple brilliance : Restart on Failure , has with a small change in the CoSy DOS BAT , changed what required a tek nerdy visit to DOS into a mere hiccup .
o A quick demo of the use of CoSy for everything from accounting to mail list management will be given .
o CoSy is out to change the interface between the user & their computing assistants from the walled kindergartens of icons & menus to simple yet deep language .

People whose nouns ( data ) have currency symbols associated .
Direct personal support for Owners , Investors , high net worth individuals
in their personal use of CoSy for dealing with their Everyday Business of Life .

but those making decisions controlling the $$ flows .
https://redwirespace.com/about/leadership/
The ` Vision Programming -- Melding Iverson & Whitney & Moore --
is largely complete . Future evolution only now opened up .
My focus must be at the ` Business level --
clients on one side -- development programmers on the other .
Needs expertise in standard systems : sockets webbrowser interface server .
But also w/i CoSy Forth itself .
Enormous number of enhancements & polishing w/i one sentence .
Only most talented programmers useful . CoSy must be able to match SV $$ pay .
Contact me if you see yourself fitting into this ecosystem in any relationship
from the business client , to the teky project .

From recent em> Re: Best wishes for the conference :
A recent email w Dr Happer , tho , may be worth mentioning .
To paraphrase :
The gray body temperature around our orbit is ~ 278.6 +- 2.3 from perihelion
in January to aphelion in July .
If anything is detectable in mean global temperature data , this
~ 4.6 degree peak to peak variation whose phase is known should be
very clearly visible , if anything is , in annual data averaged
over a number of years .
Yet I have never seen a paper or discussion of this most basic effect ,
much larger than the total variation this debacle is about .

WHEN YOU ARE THINKING OF USING PYTHON or other Mass Market Language
THINK OF TRYING CoSy INSTEAD
IT IS OPEN FORTH AND MORE ` POWERFUL
And you will be helping develop an openly Forth environment

Answers :
Q0 : Download & start /\
` \4thCoSy\CoSy\CoSy.csy startJob
Q1 | How do I save all my Notes and Environment ?
. Control s
. F6 saves environment before executing line .
. F11 inserts a timestamp and saves environment .
These make a *.bk copy of the previous save before executing .
. saveTSclone | near the top of ` state Saves Timestamped clone
These save the ` Root dictionary ` R as a ` .csy file .
Q2 | What am I looking at ?
The standard Job environment has 3 windows
`( res text state )`

Q3 | What does the CoSy vocabulary build upon Forth ?
http://cosy.com/y21/Wed.Mar,20210310.html#4th.CoSy
http://cosy.com/y21/ApolloDesignPrinciple1.jpg
Reference Counted Lists with a 3 cell header .
`( Type # Ref# )`
` Ref# | is mainly internal manages dynamic
` Type | allows ` generic verbs to know their meaning wrt arguments
` # | is count , like in a counted string .
Type 0 is general list : list of pointers .
hex `( Type0 TypeC TypeI TypeFl TypeS TypeV TypeA TypeFv )` .. ' See 'm ,L flip decimal
A dictionary is a list of 2 correlated lists `( names values )`
The entire environment is in a ` Root dictionary ` R
R `( Type # Ref# )` >t0> ' Eval 'R >t1>
t0 t1 ,L fmttbl|
R 0 _at >t0> | names of items in Root
R 1 _at #' >t1> |
t0 t1 ,L fmttbl|
Q4 | Important Vocabulary ?
Rich APL > K evolved vocabulary
http://cosy.com/K/html/kref.pdf
s" " Words #
2 quite important words
` | returns the next word as a string . Like s" word"
' | returns the ` xt , the address of next word
| ' is what makes it relatively simple to implement
APL ` operators aka ` adverbs , eg: Iterators
` atomic verbs apply between each item of arguments
i( 1 2 3 )i i( 10 20 30 )i +i
Iterators factor out looping by using #
and Type to know know apropriate algorithm to apply
`( 'm 'd 'L 'R ./ .\ ': f? )` ' :?? 'm
These ` adverbs take 1 or 2 ` nouns and a ` verb and apply the
verb over each item in the noun(s)
: dotProduct *f ' +f ./ ;
f( 2 )f f( 10 20 30 )f *f ' +f ./ | dotProduct
Indexing is modulo .
Generally shorter list is cycled thru to match longer
Main ` help words
`( ?? :?? Help See )` ' :?? 'm
` dup See
Large vocabulary of slicing , dicing & finding words . eg:
` csv>lst :??
| *** Accounting *** | is of special importance |
| All accounting for CoSy the enterprise will be in CoSy the language
(' 20211111.0000 _f ` PSBT ` BH 104.56 _f s" auto " ')

Q5 | What's the future ? Creating a cash flowing ecosystem
. Clients who need to do in minutes was may take hour in raw Forth
or do in days what what would take weeks .
either prototyping or finished system .
. Complex , multidimensional math . eg: voxel model of planet .
. The most Highly Talented Programmers to
polish CoSy , support Clients , evolve CoSy .
REPLACING IUP GUI WITH SOCKETS >< WEB BROWER SERVER INTERFACE
. Extracting portions of vocabulary to implement dynamic objects

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.

Forth vs C NOT Javascript or Python
MUCHLESS CoSy
But CoSy is just an open vocabulary in Forth
Definitions on the scale of ` words , not ` programs

FAR more complicated to go thru virus exception setting and downloading
than actually using and learning CoSy
Thus setting up turn on & tap the CoSy button Computing Box .

Forth -- APL | CoSy opens up a new vista of language evolution |
Factoring out looping itself into a few words taking functions
to be looped over as arguments .
MY IGNORANCE OF ANYTHING OTHER THAN APL>K FORTH CAN'T BE OVERESTIMATED
OPEN FROM THE MATH TO THE CHIP
| PRACTICAL | AMBIENT | IRRITATION DRIVEN DEVELOPEMENT
if can't execute each line as you compose a verb , not competitive .
Forth gains tremendous power by not doing things .
REPL | IDE |
nested ( recursive ) ' { ' } | clean quotations ~ ['] |
Levels of consolidated vocabulary
adicity
! control over TUI ! | Ting & Nelson HTTP interface .
s" ./CoSy/Tui.f" F> | not Functional !
Work thru problems a thought at a time .
