I have been for years an enthousiastic reader of Dr. Dobbs Journal, a software magazine where programmers talk to programmers. DDJ has always been for me a reference, providing accurate and timely information with a practitioner's point of view.
I learned a lot from DDJ about technology itself and the way to apply it. I used to subscribe to the paper edition (probably sent via sail-mail, since it always took about 3 months to reach Paris...), before it became web-only.
This is why I take special pride in having made the headline of Dr. Dobbs Update with Ateji PX in an article by Jon Erickson, DDJ's editor in chief, titled "Think Parallel, Think Java".
