The OpenBSD 4.0 Crash Course Available

I've spent the last several weeks writing, revising, and editing a project called The OpenBSD 4.0 Crash Course for O'Reilly Media. It is designed to quickly teach you the basics of how to install, configure, use, and upgrade the OpenBSD operating system as a desktop or server. It's specific to version 4.0, and I plan on writing a new version for each future OpenBSD release. If you've wanted to learn OpenBSD or are anxious to get into the BSDs in general, this is your best starting point. I decided to pitch it as an electronic guide because it doesn't need to be particularly long, it's possible to copy-and-paste commands from it to your terminal window, and you can print out a hard copy if you want. It's now available for download for U.S. $9.99 from O'Reilly, and I plan on donating a portion of my royalties to the OpenBSD Project so that it can continue to produce great software. Each section is designed to be like my how-to articles -- concise and easy to understand. There are no preambles or politics; just good information. Below is a sample from the book to show you what you can expect from it.

Why Everyone should know vimVim is an improved version of Vi, a known text editor available by default in UNIX distributions. Another alternative for modal editors is Emacs but they’re so different that I kind of feel they serve different purposes. Both are great, regardless.
I don’t feel vim is necessarily a geeky kind of taste or not. Vim introduced modal editing to me and that has changed my life, really. If you have ever tried vim, you may have noticed you have to press “I” or “A” (lower case) to start writing (note: I’m aware there are more ways to start editing but the purpose is not to cover Vim’s functionalities.). The fun part starts once you realize you can associate Insert and Append commands to something. And then editing text is like thinking of what you want the computer to show on the computer instead of struggling where you at before writing. The same goes for other commands which are easily converted to mnemonics and this is what helped getting comfortable with Vim. Note that Emacs does not have this kind of keybindings but they do have a Vim-like mode - Evil (Extensive Vi Layer). More often than not, I just need to think of what I want to accomplish and type the first letters. Like Replace, Visual, Delete, and so on. It is a modal editor after all, meaning it has modes for everything. This is also what increases my productivity when writing files. I just think of my intentions and Vim does the things for me.
