I decided to give Apache Ivy a try. I was looking at an old Ant build, and I was toying around with the idea of just "adapting" it to a repository manager. I fooled around with Ivy a bit. Had it retrieve some artifacts from an "ibiblio" repository type. Ivy, for some reason, calls the Maven repository format an ibiblio format. This would make sense five years ago, but now it is just an odd anachronism.

The basic performance of Protocol Buffers in a simple, unscientific experiment...

This is something of a coup. For countless years I avoided PHP like it was a disease. I viewed it as a half-language. The implementation technology one would use as a last resort. "You program in PHP?" "Surely, you jest."

I've had a few requests from readers to create PDFs of individual chapters. Maybe you need to bring a team up to speed on a particular component like Commons Lang or Commons BeanUtils and it makes more sense to send people a focused, 20-page chapter on a single topic? Whatever the reason for the request, I decided to change the book's build to add these separate chapter downloads.

The Common Java Cookbook is now available in an ePub format. To download the ePub go to click here. The book is freely available, but you will need to sign up for an account with Discursive before you can download the book.

Happy reading. If you have any feedback about the ePub specific formatting, please send an email to feedback@discursive.com.
