Matthew interviewed the authors of one of the best books for learning systems administration with Unix or Linux from a large, enterprise perspective.  This book is unusual in another way: it was published by Prentice-Hall and the forward was written by one of their competitors, Tim O'Reilly, the founder and head of O'Reilly Media. That says something. Aside: Matthew has written for both.

The interview with the authors appears on InformIT's website.

Matthew had the privilege of being one of the tech reviewers for Ubuntu Up and Running.

Matthew occasionally writes articles for Talk Morocco. Talk Morocco is a website dedicated to discussions related to Morocco, its people, society and culture.

Matthew has a friend, Scott Appleman, who has started a cool little indie zine called Dove & Snake.

Matthew (gladly) let Scott and the D&S crew reprint a chapter from his most recent self-published, Creative Commons licensed book Nowhere Else to Turn in their most recent edition.

Matthew had the privilege of helping out with one chapter in The Official Ubuntu Server Book--he didn't do enough to earn an author's credit or get a mention on the cover or anything, but Kyle Rankin was kind enough to mention him in the Acknowledgements on page xxiii. Matthew would like to thank Kyle and Mako for the chance to contribute. It truly is a wonderful book.

There are things that happen in the world that are difficult and sometimes impossible to explain. At times, we are confronted with circumstances or situations over which we have no control. How we deal with those situations reveals much about our strongest beliefs, our dreams, and our fears. This collection of short stories explores specific instances of involvement with or belief in the supernatural in one North African country. The tales, all claiming to be true, were collected over several years while the author was living in Morocco.

Matthew has several articles he wrote, and one he co-wrote with a friend, Ryan Troy, in the Ubuntu 8.10 edition of Linux Identity. He also wrote the editorial at the beginning of the issue.

This project started as a language learning experiment. Matthew Helmke was sitting in a cafe with a Moroccan having a discussion in Moroccan Arabic. The friend told a joke and it was quickly discovered that vocabulary alone would not ensure an understanding of humor. This prompted a question, "What did I miss?" In this book, Matthew Helmke explores the hidden aspects of Moroccan culture. These are the things that Moroccans know inherently, without being taught. The result is an intriguing look through the eyes of an American trying to make sense of Moroccan culture.
