Even if it is a few years old, I would still use the book from 
Ali. Most is still valid and maybe, the online version is even 
updated, but I'm not sure on this.

A completely other approach is to try to help fixing bugs. I 
learned a lot about D, when I started doing so.

I don't know, if that is, what you wanted to hear, but I thought, 
it wont hurt telling you. :-)
