If you are one of those people who just don’t get the usefulness of the D Programming Language, it would be helpful to subscribe to the blog of Bartosz Milewski. Not all of his posts are related to D, but a number of them are. And give the depth with which he discusses complex topics, I’ve not seen a post I didn’t find interesting since I subscribed to his feed.
His latest post is on const transitivity. He first discusses the reality of transitivity in C++, before moving on to the goals for transitivity in D. If you go through his blog, you’ll find other posts on const, and a number of posts on multithreaded development. For the D skeptics, I recommend the D Programming Language category for a little bit of education.
