Good idea. Small notes:

*) In the tip section 'write("Hello\n") and writeln("Hello")' are not
the same. writeln and writefln flush. write doesn't.
*) Not sure if you want to also encourage portable code. "\n" should
be replace with newline which I think it is define in std.string.

Thank you for that.

Everyone is welcome to contribute.  (It can be done faster and better that
way)

I wrote some code a while back that was intended to be portable (between windows and linux anyway). I used 'writef("Hello\n");' a lot, and those always printed correctly on windows. Does writef do something different than write with the '\n' character?

The command line console may deal with it okay but here are many Windows programs that assume that newline is '\r\n'. That is the same problem with '\\' and '/' for path separator. Some tools handle both while others only handle '\\'.

(I can't see Jose Armando Garcia's answer to this question. For some reason it appears empty in my news reader (Pan 0.133).)

As far as I know, "text mode" file access already translates those characters. '\n' always means "new line" to be replaced with each platform's correct code sequence.

I've done some major restructuring to the ebook.  Now, the link to the first
lesson is:
http://en.wikibooks.org/wiki/D_(The_Programming_Language)/d2/Phobos/Lesson_1
There are 7 lessons currently.  Lesson 3 (Functions) and 9 (Slicing) are not
written as of now.
If you contribute, please add yourself to:
http://en.wikibooks.org/wiki/D_(The_Programming_Language)/Contributors

Please, do feel free to add content, tips, and code.  There's no errata;
just fix it, that's all.
Anybody know a good idea for a picture to put in the index page:
http://en.wikibooks.org/wiki/D_(The_Programming_Language) ?

Thanks
Jimmy
