Or, how I learned the history of the computing industry and Unix by looking at the cover of a book.

Here’s the deal. For reasons best left unexplained, I have every edition of the Unix System Administration Handbook by Evi Nemeth, et al. I even have the Linux System Administration Handbook. Since every book’s edition is a different color, my daughter likes to play with them. The other day, while putting them back on the shelf, I noticed that the cover of the book reflects the history of the computer industry, the history of Unix, and a little history about Evi. So without further ado, here’s my explanation of what it all means. You’ll have to excuse the quality of the images, but I don’t have a scanner so I took digital pictures.

Unix System Administration Handbook, 1st Edition

Unix System Administrator’s Handbook 1st Edition
Unix System Administrator’s Handbook 1st Edition

This book was published in 1989. We see that UNIX system administration is a difficult topic. There is a Unix system administrator driving his car towards a cliff. I don’t know what the reference to cranberry bogs is about, but let’s focus on the colorful characters.

Starting rom the left, we have a dog named biff, which is a reference to the biff(1) command in Unix that prints a message to your terminal when you have new mail. In the center is a daemon, a Unix process that runs in the background. Since the daemon is showing us his watch, maybe it’s the NTP daemon? At the right of the daemon, you can see the finger(1) command, used to find information about a user and made famous by the Great Worm of ’88. I don’t know what the other two characters (the owl, and the cat, or is it perhaps a lady daemon?) are about. If anyone knows, or has a guess, let me know.

Unix System Administration Handbook, 2nd Edition

In the second edition, published in 1995, biff is dead (you can see the gravestone that says “R.I.P biff R.I.P”), probably replaced by POP. The cross behind reads “USL” and is a reference to the Unix System Laboratory at AT&T, the group responsible for System V, which had been sold to Novell in 1993.

In the front of biff’s grave, it says “Here lies the entire Berkeley CSRG”. That means the Computer Science Research Group, which was responsible for the development of the Berkeley version of Unix, called BSD, at the University of California and was disbanded in 1994.

The first edition of the book is being held by the paw of a cat. We can tell it’s the first version because it’s yellow, and it says “USAH”, short for Unix System Administration Handbook.

The dog, Biff, is now gone from the front row. He’s dead, remember? And has been substituted by a Monkey, a spider, and a Web. I don’t know what the monkey has to do with anything, but the web is clearly a reference to the World Wide Web, which was invented in 1993. The spider is clearly a reference to the web spiders, or bots that search engines use to index web sites. We can still see the daemon, the finger, and a new character, Dr. SNTPd, a reference to the Simple Network Management Protocol.

Note that the car is more modern, and it has the word “Unix” written on the front. Also the System Administrator behind the wheel appears to be a woman. Could this be a reference to more women in system administration?

Unix System Administration Handbook, 3rd Edition

The third edition, published in 2001, has many of the same symbols as the second edition. In this edition, however, there’s a new tomb. The Unix to Unix Copy Protocol, or UUCP, has died because most people use PPP by now. We can also see the second edition coming out of the grave being held by a tentacle.

Two more things should be noted. First, this is the first edition of the book to cover Linux, a newcomer to the Unix world, and you can see the Penguin in the co-pilot seat of the car. Also, the spider now has handcuffs, which might be a metaphor for the restrictions many sites started putting in place to prevent search engines from finding them.

Linux System Administration Handbook

This book came out in 2002, and was made specifically for Linux, which had by then surpassed in popularity all of the other Unix distributions. You can see the Linux Penguin driving now, and the sys admin as the co-pillot.

The spider’s handcuffs have been replaced by a shackle, meaning the restrictions on spiders are greater now. The other books are gone, as Linux has been declared the only winner.

You can also see that the sign that used to read “Beware! Vendor Gratuitous Changes Ahead!” has been replaced by one that has Unix somewhat deviated, but still going up, Linux going straight up, and XP (a reference to Windows XP) going down. The helicopter that is crashing also has XP written on it. The authors have no love for Microsoft’s Operating System.

There is also a penguin skiing on the mountain. I have no idea what that means.

The last interesting bit is that there is a sailboat in the back. Let’s take a closer look at that sailboat.

See the name on the boat? It’s the name of the main author of all the books, Evi Nemeth, who is now retired and sailing across the world.

Cool, isn’t it? Robert Langdon isn’t the only one that can find hidden symbols everywhere.

These are really good books by the way. You should probably get a copy of the Linux version.
