if people find
<br>this thread off topic. If they can point me to an appropriate place

<p>Secondly, all I have is my hands-on experience - I'm pretty low on

<br>I'm only going to mention two: 1. patterns, and 2. the prototype
<br>Patterns have been heavily discussed elsewhere. So the key points I
<br>want to raise are: a. they provide a way for "experience or the
<br>defining concepts" to be noted, b. they enrich the vocabulary of the
<br>pattern users and c. the patterns often work in unison.
<br>Patterns crop up everywhere, architecture, object oriented design,
<br>organisational structures (See Jim Coplien). Maybe even stories and
<br>Hollywood Movies if you consider Campbells' "The Hero with a Thousand
<br>Faces" and Vogler's "The Writer's Journey". My last job involved
<br>assessing tons of business plans for a major technology incubator and

<br>(B2B, ASP, RFP, etc)!!!! Patterns seems to be self standing. Perhaps
<br>someone has put in some thought about a pattern language for
<br>So there is a good chance that there are "patterns" for prototypical
<br>structures. I struggled with OO concepts for years which was
<br>confounded by using C++. The GOF Design Patterns book really helped
<br>me to understand OO by the medium of patterns. However, I still get
<br>frustrated by core OO concepts. I helped to design and implement an
<br>OO framework based on a generic opaque object. The interface of the
<br>object followed the Composite and Prototype design patterns. Parent
<br>an child nodes could communicate to each other (ie two way
<br>delegation). This was enough to quickly create different complex
<br>structures for example to mimic inheritance, polymorphism,
<br>encapsulaton (ie metaclasses). This has helped me understand the
<br>inner workings of OO much more. Then I discovered Self and prototype
<br>paradigm which I felt very comfortable with. I now feel pretty stupid
<br>since I realised I was using a prototypical approach to create
<br>traditional OO structures just like how I used C++ as a better C a
<br>long time ago! But then again this may be correct. Perhaps the
<br>problem context is such that the forces to be balance require
<br>class based solution. Therefore, inheritance, polymorphism &
<br>encapsulaton could be prototypical design patterns ???
<p>The GOF book (I think) advocates delegation over inheritance. I'm
<br>confused how to compare delegation to design patterns. Maybe the PHD
<br>is available online ?
<br>Is your own ecodesign model available on a web site somewhere, I'd
<br>love to read it ?

<br>> Dear Bharat:
I am also interested in showing the superiority of
<br>> prototype paradigm to express complex concepts.
<br>> There are many people dealing with prototypes or delegation.
<br>> But no language has reached the level of development of the
<br>> Self language.
<br>> At the right moment based on Günther Kniesel's PHD thesis
<br>> I am trying to figure out why he argues that delegation is
<br>> far better than design patterns.
<br>> Since I am an architect and I was expected to unfold my PHD under
<br>> the advising of Christopher Alexander, the author of the A Pattern
<br>> Language, I would not deny the importance of this trend.
<br>> My contact with Alexander began in 1990 and lasted until 1992.
<br>> at this time computer scientists showed interest in mimicking
<br>> computer science what he did in architecture.
<br>> I have unfolded my own ecodesign model - or the domain dependent
<br>> model entitled THe model of Primary, Secondary and Tertiary Waves
<br>> to plan and design sustainable cities. It is an appplication of
<br>> catastrophe theory, graph theory, semiotics, symmetry groups of
<br>> the plane and the dotless plane. Its hermeneutic nature tunes
<br>> well with the hermeneutic (really musical) Self nature.
<br>> I am trying to unfold a tutorial in Self and so the core of the
<br>> necessarily must deal with your concerns, because it is very complex
<br>> to implement concepts about sustainable cities.
<br>> Alexander agrees it is far more complex and complete than his
<br>> A Pattern Language.
<br>> What I object to A Pattern Language is that Chris had not developed
<br>> a correspondent geometric modeling (even less a computational
<br>> Likewise the Gang of the Four has not focused on developing language
<br>> constructs that would correspond straightforwardly to the design
<br>> I am reading an interesting paper from Jan Bosch that shows how to
<br>> this. Unfortunately he does not use delegation.
<br>> Kniesel in his thesis wants to show the superiority of delegation
<br>> I am still reading through his thesis and the papers I gathered and
<br>> have no conclusion.
<br>> But I would be happy if the researchers joined us in this important
<br>> I've read through the book "Prototype-Based Programming: Concepts,
<br>> Languags and Applications" which provided lots of useful background
<br>> Like OO analysis & design, I'm interested in analysis, modelling
<br>> application design techniques for the object-based prototypical
<br>> paradigm. The implementation would be done in an object-based
<br>> language like Self.
<br>> Can anyone point to any online research material or book reference
<br>> I am exhausted now and recovering...But I hope we can trigger off
<br>> a discussion and I promise to give the references gladly.
