Once the boilerplate traditionally associated with the Service Locator Pattern is eliminated, one of the key motivations for Dependency Injection is reduced, if not eliminated. This article, the second of a two part series, looks at the pros and cons of each approach to interacting with services.

Traditional implementations of the Service Locator Pattern result in a large amount of boilerplate code. This article, the first of a two part series, shows that this is not a necessary weakness.

Having spent nearly two years "getting everything sorted" ready to write my next book, I've decided enough is enough. It starts TODAY!

Two radically different philosophies to the management of software developers. Which one do you favour?

Just yesterday at work I had a good real-life use case for generic functions which deserved a blog post.

This final installment documents other subtle and somewhat surprising features of Python's super.

The series about the dark corners of the Python builtin super continues. In this installment I discuss an ugly design wart, unbound super objects.

I will be giving a 3-day Java & Python Patterns workshop in Sao Paulo September 15-17, and then the keynote at the PyConBrasil in Rio de Janeiro September 19.

James Ward and I have been working on an introductory Flex book for programmers, which we'll release as soon as we get the legal issues ironed out.

A non-Web-2.0 (TM O'Reilly, Inc.) way of looking at it.

You need coders to write software - its that simple.

super is perhaps the trickiest Python construct: this series aims to unveil its secrets

I describe my publication toolchain for Artima blog posts. I also argue that the absence of features in the Artima blogging platform is its best feature.

In the first part I have discussed the new features of metaclasses in Python 3.0, in particular the usage of the __prepare__ classmethod to intercept the class attributes *before* class creation. In this second part I will show an example of the things you can do with metaclasses, by implementing a clever record system.

This is the English translation of an article I wrote some time ago for Stacktrace: http://stacktrace.it/articoli/2008/01/metaclassi-python-3000/ For convenience, I have split it in two posts.
