K.CoSy NoteComputing Newsletter200305
Arthur Whitney's K is by many measures one of the most powerful programming languages .
K.CoSy turns it into an interactive "NoteComputing" environment .

" So well done, CoSy has stimulated me into trying to learn K "
After 17 years living in my CoSy "notecomputing" environment created in STSC's flat APL+PC , I have since Thanksgiving 2000 created a similar working
and programming environment in Arthur Whitney's K language and its tightly coupled GUI . ( See http://Kx.com )

Already K.CoSy provides an extremely productive workspace like
environment previously impossible in K which is itself one of the most expressive and perhaps the fastest language yet created .
Among my uses of K.CoSy is the preprocessing of these web pages with a small vocabulary I have constructed to allow embedding of arbitrary K expressions in my HTML . ( View the source of this page for a couple of examples of embedded K . )
If you have an interest in exploring K , K.CoSy's open definitions , interactivity , and memory of every thing you do , greatly ease the task .
The only silver lining to the horrendous disk crash I suffered mid June is that reconstructing from scratch , the code is much cleaner and more mature .
Caution : K and K.CoSy must be considered eXtreme programming environments .
If that appeals to you , prepare to be amazed . If not , K and K.CoSy may be totally inscrutable to you .

|| Here is what you see when you click "click to start" opening K.CoSy .
Click .CoSy.text to see the whole contents of the variable `text when you first load the current version K.CoSy .
These should give you a flavor of the open nature of K.CoSy and a glimpse of its broad utility .

K.CoSy , being young and developing open code , lends itself to offer by subscription .
SORRY , charter subscriptions have done their job and are a thing of the past . Please contact us directly about integrating CoSy into your business life .
Charter subscriptions are available for just $30 .
Subscription includes access for one year to the source files in the protected MEMBERS directory and the ability to post to the group ( and , of course , to ask me any usage and technical questions . . Current members of the CoSy/Notecomputing group are automatically Charter Subscribers with full access privileges .
To become a member of CoSy and experience its extreme simplicity :
This is all very fresh , please contact me with any questions or suggestions .
- Go to Kx.com and download a copy of K ( or Kdb which includes K ) . Download their docs too ; CoSy assumes you know or want to learn K . CoSy does a lot to tame K , but you will see what a wild mindmeld Arthur has condensed .
- Subscribe to K.CoSy NoteComputing Language Pool .
Drop me an email
or give me a call letting me know you are writing a check .
- I will then add you to our members' mail group , and email you the information to access our members' directories and files including how to download and setup K.CoSy .
