<h2 class="first-section-title"><a name="46"></a><a name="introlev1sec10"></a>Warning</h2><p class="first-para">In this book I provide some rather intricate, and potentially dangerous, source code examples. This is what happens when you go where you are not particularly supposed to be. I recommend that you use an expendable test machine to serve as a laboratory. Also, you might want to consider closing all unnecessary applications before experimenting. If an application dies in the middle of an access to disk, you could be faced with a corrupt file system.</p>
<p class="para">If you keep valuable data on the machine you are going to use, I suggest you implement a disaster recovery plan. During the writing of this book's manuscript, I made a point to perform daily incremental backups and complete weekly backups of my hard drive. I also had a secondary machine that mirrored by primary box. Large corporations, like banks and insurance companies, have truly extensive emergency plans. I toured a production site in Cleveland that had two diesel fuel generators and a thousand gallons of gas to provide backup power.</p>
