Implementing a blog in Common Lisp: Part 2

Velte continues his interesting tutorial.

(defmethod initialize-instance :after ((obj blog-post) &key)
"If :url-part wasn't non-nil when making the instance, generate it automatically."
cond ((eq nil (url-part obj))
(setf (url-part obj) (make-url-part (title obj))))))

The above is an interesting example of "aspect-oriented" programming!! Note the :after keyword and the typng of the argument.

I haven't had time to set this all up and follow along yet, perhaps next weekend will be quieter!!

More on CouchDB

The SimpleDB comparison in this post seems very important

clipped from www.google.co.uk That's a great development. Good for IBM picking it up, too. Not knowing CouchDB too deeply, but the basic gist of it, I wonder how well the approach would translate into a cloud-based system, not too unlike Simple DB?

Damien Katz of CouchDB Joins IBM

clipped from www.google.co.uk Great news! I've accepted a permanent, full-time job with IBM. My primary duties are (drumroll....) CouchDB! So all the stuff I've been doing up until now for free I'll be doing full time and be getting paid for it! Yee Haw!
