 Dear K.CoSy Charter members and friends of CoSy ,

 If you have visited  http://CoSy.com  recently , you will have seen
 that the period of charter subscriptions at a token cost , they having
 filled their purpose , has passed . It has produced a strong
 understanding of CoSy's powerful advantages over tradition styles of
 interface among a nucleus of individuals who took advantage of the
 charter availability .

 During this year , I have also evolved the mechanisms and usages of
 CoSy so that all my various responsibilities , the timestamped records
 of the relationships , their transaction histories , and the necessary
 tax filings , are current and reduced to a fraction of my time .
 I have also embedded in  CoSy  ( and my own experience ) the life cycle
 - the formation , accounting , and equitable dissolution - of a small
 partnership . I should have been spending my time pruning and shorting
 my portfolio , but trading seemed such a secondary activity compared
 with the potential of direct creation .

 Trading for your family's account , tho , is the ultimate
 responsibility if your family's assets are in the form of securities .
 The server-side support for such activities is , of course , the
 domain  K  rules . ( see   http://island.com  for example . )
 This activity is now sets the value of my time .


 Now that the Charter period is over , CoSy will focus on several
 markets .


  Current  Kx  customers  
 Here the issue of an individual client-side license for the K
 underlying  CoSy  is not an issue . If your corporation already
 is a client of  Kx Systems , we should talk .

CoSy , the  K IDE  
  CoSy is the only  Interactive Development Environment (IDE)
  available for  K . I must admit I am itching for opportunities
  to benchmark its productivity against the  scripting-compiling
  environments commonly used for K programming .
  CoSy is compatible with  Kdb  , and I seek tasks that expand
  the synergy between the two .

Teaching K  with CoSy 
  CoSy , being an interactive notebook , is incomparable for
  teaching  K  in a simple step by step fashion where each line
  can be replicated , dissected , reexecuted  with immediate
  results displayed , all saved with a keystroke .

  Working literally from within the K-tree , the concepts and
  subtilties of  K's  structure and notation  become immensely
  more tangible and therefore learnable . Thru presenting
  CoSy and K to a wide variety of people , I have refined the
  sequence of introduction of concepts to ease the path to
  understanding of Arthur's remarkable creation .

  If you are a client of Kx and have personnel , perhaps including
  yourself , to whom knowledge of , or a deeper knowledge of  K
  would be valuable , we should talk .


Consulting in  K  with CoSy  
  Implicit in the above is that I am seeking consulting tasks in
   K and Kdb  to test the reality of my rhetoric .  I look forward
  to working with the Kdb and large systems experts whose knowledge
  of these environments is so complementary to my own concentration
  within  K  itself .

 All of these uses bundle the necessary CoSy license .


  Potential Kdb server customers  
  If you have leading-edge large scale quantitative database
  serving applications where  Kdb technology is uniquely capable ,
  let  us  pull it all together for you with the added benefit
  of CoSy as an interface for your most sophisticated users .


  Independent Client-side KoSy  
  The highest value use for  CoSy  is clearly as the personal "noteComputer"
  for quantitative individuals who run their own affairs , whether family
  or business . This requires a substantial amount of personal tutoring
  and customization embedded in a top of the line  Sony notebook .
  At this point in time , this can only be supplied with  Kx's free
  download license which , while pointing out a history of 5 years
  availability , Kx reserves the right to revoke at any time .

   We are continuing to work hard to resolve this difficulty , but in
   the nonce , we will be working to demonstrate the value of the
   CoSy interface to K within the Kdb server market .

Charter Subscribers  
 I do plan to continue to aperiodically upload updates to the basic
 CoSy.csd which is on the CoSy Members page .  As Charter subscribers ,
 you will continue to have access until the end of October , or
 anniversary of the date of your subscription , whichever is later .

 If you not a customer of K  but are finding CoSy of significant
 value to you , and can accept the limitations of the current K
 license , let me know .
 In any case , let me know . Your perception of the client-side value
 of the power of  K  , made comfy by CoSy , will build the case for an
 appropriate licensing structure .


Thank you all for your early support .
You have played a role in the creation of
an ultimate built on an ultimate .
