Arc v' Objects and the Web

Trying to re-use a message board is not a good example of component architecture. Being able to trust small, tough, and smart components is.

Linking to David Heinemeier's weblog and assorted thoughts about agile web development.

There are some places where traditional transactional systems have caused problems for some of our applications. I'm finally starting to come to grips with the world of asynchronous messaging, and how it might help us in the future.

This post on the wdf-dom mailing list, which covers both large projects and large issues with JavaScript/DOM development, is fascinating to me. Also a very very quick look at Nevow's LivePage technology.

Joel Spolsky has a very interesting article about How Microsoft Lost the API War

Python is an excellent "solution building" language, great for building applications out of various services and components. But it can ably produce those too.

Considering process heavy domain models versus process heavy service layers, I still don't know the best place for so-called "business logic."

Making a Page Messenger service to simplify sending and retrieving messages for web visitors opens up some interesting new possibilities.

A [seemingly] Struts influenced new Python web app server/framework, using mod_python and Zope's Page Templates.

Very quick thoughts about rule based rapid application development.

Review of a review of "Extreme Programming Refactored," which is primarily some personal thoughts about XP, its good and bad points, and why "throw-away prototyping" seldom works.

As storage interaction mechanisms are becoming more abstract in my projects, a Schema Validator pattern has started to emerge as a means of ensuring what I store is in the format desired.

A look at yet another "death of classes" post. I don't think classes are dying, but they have been terribly abused over the past decade. The tide is finally turning to smaller hierarchies and collaborating objects. I share some recent experiences with applying Zope 3 component style patterns to Zope 2 projects.

This week, I apply my RDBMS abstraction patterns to LDAP for delightfully rapid results.

A long post documenting a transition from chasing pure object-relational mapping to componentizing the data manipulation sequence and freeing myself of many headaches in the process.

A surprise series of events leads to a long-desired leap in architecture on a pair of Zope projects. One of the catalysts was a "From CMF to Zope 3" slide from Tres Seaver stating "Pluggable components are good; configurable components are better." The other catalyst was an application of a massive speedup to a critical piece of business logic in one application that had to be placed in another, only to realize how much the two code bases had forked - all in an area of customer-specific data requirements/configurations. In the course of a few hours, a configurable component solution steps into play to wean us off of the software configuration management difficulties presented by keeping important code in ZODB placed scripts. All this was done by using some common sense component design techniques, a bit of refactoring afforded by moving large scripts into classes, and use of Formulator to describe component configuration schemas.
