Hello, everybody.

Not much to report this week. On the book front, I’ve uploaded chapter 5 (previously available only as a series of posts) as a PDF file; it’s on the drafts page with the others.

In other news: like many others all over the world, the Ballabio household is celebrating Christmas.


The schedule of this blog will be affected: I won’t be posting over the holiday. You’ll hear from me again in January. Have a nice holiday, everybody!

Follow me on Twitter if you want to be notified of new posts, or add me to your circles, or subscribe via RSS: the buttons for that are in the footer. Also, make sure to check my Training page.
