Book Reviews: Active Java and Exploring Java
Title: Active Java: Object-Oriented Programming for the World Wide Web
Author: Adam Freeman & Darrel Ince
Title: Exploring Java
Author: Patrick Niemeyer & Joshua Peck
Publisher: O'Reilly & Associates
Reviewer: Danny Yee
Somewhat bemused by the marketing frenzy and in no particular hurry to learn yet another programming language, I have refrained from asking for review copies of any books on Java. Nevertheless, a few turned up on my doorstep anyway, and I found it hard to resist finding out what all the fuss is about.
The first book to arrive, and the only one I read right through, was Active Java. This is an introduction to Java aimed at those having basic programming competence but no experience with an object-oriented language. The book works its way through the elements of the language, explains how to use the awt and net libraries, introduces the Java Development Kit and the basics of writing applets and applications—and then concludes with a chapter on Java internals. The emphasis is on covering important ideas and concepts rather than on providing details. Active Java is easy to follow and clearly laid out, and I recommend it for anyone wanting a broad overview of Java. I think it would also make a good textbook for an undergraduate course, though it lacks exercises and is perhaps not repetitive enough.
As a supplement to Active Java, and a source of more detailed information, I used Exploring Java. This begins with a brief look at internals and security issues and then launches into a basic “Hello Web!” applet. This book contains detailed descriptions of the basic classes and standard libraries and is clearly aimed at experienced programmers who want to learn Java in order to write serious applications.
I have only glanced at the three other books on Java that arrived; Java in a Nutshell (O'Reilly) looks like a reference for the serious Java programmer; On To Java (Addison-Wesley) is a textbook with an unusual layout, using paragraphs numbered sequentially throughout; and Learn Java on the Macintosh (Addison-Wesley) comes with a Mac version of the Java Development Kit on CD-ROM. Anyone looking for a book on Java should search carefully: as even this small sample illustrates, there are books on Java for all sorts of niche markets. I wouldn't be at all surprised to see titles like From Common Lisp To Java For Amiga Users and 101 Implementations of Tetris In Java appearing!
Danny Yee received review copies of the books mentioned from Addison-Wesley and O'Reilly & Associates, but has no stake, financial or otherwise, in their success. He can be reached at firstname.lastname@example.org.
Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
