The Story About Ping

Summary: Provokes Young Readers' Imaginations Without Oversimplifying
Review: Like many of the reviewers, this is a book I loved as a child and that I've returned to now that I'm a parent. While it has a moral--that many times, simply accepting an umpleasant consequence is better than trying to avoid it--it's not preachy about it. In fact, what's really nice about the storyis that it's not Ping's fault that he will be the last duck to board the boat (and thus get a whack upon his back). His head was below the water at the time, and he couldn't have heard the boat master's call. I think this is what gave me a thrill as a boy. I knew that the world wasn't fair and that sometimes punishments were unjust. This is what made me identify with Ping.

And the book really taps into a young child's fears. I remember being thrilled that Ping ran away instead of accepting his punishment--what small child hasn't fantasized about running away? And I remember thinking how terrifying to wake up and find that you were totally lost in the wide world--what child's greatest fear isn't that sort of separation?

I think that's the greatest thing about this story. It's not a tidy, pat treatment of issues like children's anxieties or the value of accepting the consequences of your actions. Rather, it's a tale that provokes imagination--that taps into those fears and ideas without simplifying them. And there are too few books that do this well.

Incidentally, in terms of age, I've just begun reading this book to my four year old, and I think that's been a good age for him to start appreciating it. But I can imagine a much older child enjoying it as well.

Summary: Ping! I love that duck!
Review: PING! The magic duck!

Using deft allegory, the authors have provided an insightful and intuitive explanation of one of Unix's most venerable networking utilities. Even more stunning is that they were clearly working with a very early beta of the program, as their book first appeared in 1933, years (decades!) before the operating system and network infrastructure were finalized.

The book describes networking in terms even a child could understand, choosing to anthropomorphize the underlying packet structure. The ping packet is described as a duck, who, with other packets (more ducks), spends a certain period of time on the host machine (the wise-eyed boat). At the same time each day (I suspect this is scheduled under cron), the little packets (ducks) exit the host (boat) by way of a bridge (a bridge). From the bridge, the packets travel onto the internet (here embodied by the Yangtze River).

The title character -- er, packet, is called Ping. Ping meanders around the river before being received by another host (another boat). He spends a brief time on the other boat, but eventually returns to his original host machine (the wise-eyed boat) somewhat the worse for wear.

If you need a good, high-level overview of the ping utility, this is the book. I can't recommend it for most managers, as the technical aspects may be too overwhelming and the basic concepts too daunting.

Problems With This Book

As good as it is, The Story About Ping is not without its faults. There is no index, and though the ping(8) man pages cover the command line options well enough, some review of them seems to be in order. Likewise, in a book solely about Ping, I would have expected a more detailed overview of the ICMP packet structure.

But even with these problems, The Story About Ping has earned a place on my bookshelf, right between Stevens' Advanced Programming in the Unix Environment, and my dog-eared copy of Dante's seminal work on MS Windows, Inferno. Who can read that passage on the Windows API ("Obscure, profound it was, and nebulous, So that by fixing on its depths my sight -- Nothing whatever I discerned therein."), without shaking their head with deep understanding. But I digress.

Summary: A Story About the Importance of Home
Review: This is a delightful little story of the misadventures of a duckling named Ping. Ping hides in the weeds along the banks of the Yangtze River rather than face the spank the last duck to board his houseboat at dusk receives (I have always wondered _why_ the last duck gets spanked). The story is beautifully illustrated, and the poignant scene of Ping looking after his home as it sales away stands out, as does Ping nestled safely with his family and friends on the very last page.

This tale underscores the importance of home, of family and of belonging. It is a good bed-time book with its happy ending after Ping's narrow escape from becoming a meal. Highly recommended.
