Ted Leung on the air: Open Source, Java, Python, and ...
From the "I did not know that" department:
PJE introduced me to the Value Model pattern that originated in Smalltalk. In case you didn't know about it, here are two references that you can use to learn about the pattern. When I Googled up the papers and saw that the best reference was the article on the c2 wiki, I was going to grumble about the Smalltalk people inventing something interesting but burying information about it. Then I walked over to my (large) pile of unread books and picked up Pattern Languages of Program Design (Pattern Languages of Program Design) (the first volume of the Patterns conference proceedings), and sure enough, there's the same article that appears on the c2 wiki.
James Robertson, you can stop snickering at all us uneducated people now ;-)
some amusement as they reinvent Smalltalk, release
by release.
On the other hand, Java's standards and community
based approach is something that Smalltalk
really missed, as well as better interoperability
with other environments.
Lastly, Visualworks UI overuses the value model
concept. It is hard to determine where these
dependencies are firing in complex applications.
(That is changing somewhat in the future)
