Apache
Yesterday, Tjerk bought the Wrox book 'Professional Apache' » "You will learn from the author's real-world knowledge of Apache's intracacies and quirks, including undocumented information gleaned from the Apache source-code and his administration experience. With this book, you will avoid the pitfalls and do it right first time."
I've flipped through it last night, and I must say, it looks pretty cool. I'll have to have a closer look this weekend. Also I'll try and post some of the pictures I've made with our new camera.
