Arc v' Python

Writing some basic view objects for the simple Zope 3 todo list.

Some complain that there are too many web frameworks" for Python. I don't.

Getting back to the exploring the todo list application for Zope 3, with a nod to its inspiration.

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

Another unit test success story to remind myself the merits of testing in the future when I feel too rushed to set up that initial harness.

I took a quick look at a SQL Object Support package for Zope 3 today, and was impressed by seeing Zope 3's adaptation principles in action.

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

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

Have objects failed? One paper (which I still need to read) apparently says yes. I say, I don't think so. They've just been abused and misunderstood. But there's new hope.

A quick glance at various Form / Schema and Validation frameworks and libraries for Python and various Python web frameworks.

Another Python / Ruby comparison. Ruby's OO purity keeps the language simple on one level, but punctuation and multple ways of writing expressions bog it down. Python keeps expressiveness and symbology to a minimum.

Sometimes, our brains will just think in reverse of the code and tools we use, and there seems to...

A look at using Python's pprint module with a logging system (zLOG is used in this example) to dump readable data structures to program logs.

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.

Oh the anguish and time that can be lost to a missing brace in Javascript!

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.

In the context that "one should read and analyze source code written by great programmers to become a better...

I'm still slogging away on multiple projects, trying to bring a big mess of scripts under some more component-like control...

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. Read on for more details...
