Smalltalk-Specific Needs

(This is a slide show. You really won't get 
anything out of it unless you have a graphical web browser with graphics turned 
Satisfy intent, not letter of corporate "in the waynesses":
  • Archive your Smalltalk repository as a whole, rather than adhering tightly to an archive policy that mandates control of each "file".
  • A simple interface to stdin can allow your Smalltalk system to be constructed from within a central make file, if that is a dictate.
  • Synchronize your iterative process with the major milestones of corporate waterfall processes.
    • This will be difficult early, when the traditional process expects reams of requirements/design documents. Satisfy them (in the short term) with reams of automatically generated templates, while continuously improving your internal documentation.
    • This will be trivial later, when your documentation is realistic and synchronized with your code, and when your implementation is far ahead of normal waterfall expectations.
"...but reality dictates that we must evolve a means of interacting successfully with them." [panel 93.3] Isolate legacy systems, by:
  • Minimizing coupling -- make extensive use of lazy caching, so that your system can change independently of the legacy system.
  • Keeping legacy interface narrow and shallow: a minimum number of methods that are relatively independent of specific legacy state.
  • Providing a pluggable "legacy isolation" layer that encapsulates the legacy system and transforms it to the object system.
Maintain accountability of code that you assume is stable. Don't let "cowboy coders" into your base image!
