You’re reading Jeff Watkins’ thoughts about Web application design and development with a little bit of technology ranting thrown in for free.
I just committed change number 290 to the TurboGears subversion repository and it breaks everything!
Well, not really, but it will break every existing system using the default Identity provider (SqlObjectProvider). The reason for this change is that I misread the SQLObject documentation on joins — which is pretty easy to do because they don’t make [...]
It’s so tempting to question the decisions of those who went before you when you’re getting to know a new programming environment. There are numerous things about Python that I’m not comfortable with yet (like line continuation, why not just indent a bit more to indicate a continuation?) but overall I think it’s cool.

It’s also become clear that many people want to extend the default model to include additional fields and capabilities.
So [...]
An important part of any ORM is being able to easily query the objects contained in the database. Not every ORM handles this particularly gracefully.
Probably the most graceful I’ve seen is the Pythonic query in Dejavu where you literally write Python code which gets disassembled and turned into queries under the covers.
One of the least [...]
